How to solve the problem of weak terminal wiring

Check the quality of the terminal blocks

If you find that the terminal blocks are not securely wired, you should first check the quality of the terminal blocks themselves. Low-quality terminal blocks are often easily damaged, deformed, or lose their elasticity due to excessive use, which can prevent them from being properly tightened on electrical components. If the circuit failure is obvious, you may wish to replace the terminals with a better brand and model.

Check the insertion length of the terminal block

The insertion length of the terminal block may affect the quality and stability of the circuit. If it is not inserted deep enough, the connector can shake or break, but if it is inserted too deep, it may damage the electrical components. Therefore, it is recommended not to insert the terminal too much or too little. After inserting the terminal to the correct depth, you can use a tool to take it out to check the contact quality between it and the electrical components.

Use the right tools

It is also important to use the appropriate tools to place and tighten the terminal blocks connecting electrical components. Using the correct pliers or screwdrivers will ensure the correct grip and can ensure the reliability of the circuit through proper pressure. Also, ensure that the use of The tools is safe to avoid any injuries or accidents.

Clean the dirt on the terminals

During the operation of automobiles or mechanical equipment, some dust and dirt will accumulate on the terminal blocks, which may affect the contact quality of the terminals. Therefore, before installing the terminal blocks, the dirt on the terminals should be cleaned. You can use electrolyte or plug spray. Perform cleaning.

Ensure the contact quality between terminals

In addition to checking the contact quality of each terminal block, you should also ensure the contact quality between the cables and wires connected to the terminal block. The surface of these materials may have grease, oxides and corrosion, which will have a negative impact on the circuit. In order to improve the quality of the contact, the surface of the connection point can be coated with special types of cement, which can help make a good connection between the electrical components and the circuit.

Ensure the contact quality between terminals

In short, solving the problem of weak wiring of terminal blocks requires careful inspection and careful operation. So, how to judge whether the wiring of terminal blocks is strong?

You can refer to the following points:

1. Short circuit

If the plug and socket are not connected correctly or the plug is bent, it may cause poor contact and short circuit, which may cause the circuit to overload, cause the circuit to shut down or even cause a fire. If the short circuit is widespread, it is recommended to check and replace the corresponding wiring immediately. terminal.

2. Poor contact

Due to factors such as the quality, age, cleaning, ink, dust and contact area of the terminal blocks, poor contact may occur. This problem may cause unstable current, insufficient or stopped working power, or overload. If you find this situation, you can try to clean the terminal block or replace the terminal block to ensure that the contact area and contact are good.

3. Determine the faulty node

If there are multiple connection points or interfaces in the circuit, and there is disconnection or poor contact in only one place, you may not be able to independently locate the faulty node. If you do not know where the problem is, it is recommended that the terminal blocks of each connection point be connected. Carry out inspection and testing, but be aware that when checking the terminal blocks, the electrical equipment should have been disassembled and appropriate safety measures should be taken.

4. Silent quality inspection

During the installation of electrical equipment, routine safety checks or emergency preparedness should be carefully carried out, for example, placing equipment according to correct rules and ensuring that all equipment, appliances and materials are properly secured, before testing each terminal block individually, tasks such as installation and maintenance of all work should also be completed first.

Insufficient wiring of terminal blocks may cause circuit failure or damage to electrical components, which must be inspected and maintained immediately. When connecting circuits, special attention should be paid to the quality of the contacts and the quality of the terminal blocks to ensure intact connections.

10 key properties that connectors should have!

With the continuous upgrading of printed circuit boards and electronic components, easy-to-replace electronic connectors are becoming more and more widely used, and the requirements for them are becoming higher and higher, they are moving in the direction of being longer, more compact, and more precise. develop.

10 key properties that connectors should have

The following 10 key performance points that connectors should have

Good dielectric properties For low-frequency electronic connectors, high insulation resistance and high dielectric strength are required. Generally, the insulation resistance between contacts, between contacts and ground should be greater than 1Ω; at a low voltage of 0.44MPa, the test voltage is 500V , arc and breakdown should not occur. For high-frequency electronic connectors, in addition to meeting the above requirements, it is best to require small high-frequency dielectric loss and small dielectric constant.

High heat-resistant temperature. Generally, the heat deformation temperature should be above 200°C to withstand high temperatures during surface mounting technology or welding, and to withstand the normal heating temperature of the connector itself.

Good arc resistance, ensuring that it can resist damage to plastic caused by arcs generated during the plugging and installation process.

Good flame retardancy to prevent the occurrence of fires under abnormal conditions such as short circuits. In order to avoid the harm of toxic gases to the human body, it is best to use halogen-free flame retardant materials.

It has sufficient mechanical properties and good toughness to prevent punching; high bending strength to prevent force deformation; the specific test conditions are under certain vibration and impact conditions (vibration frequency 20~60Hz, acceleration 5g), plugging and unplugging 500 There is no mechanical damage or cracks in plastic parts.

sufficient mechanical properties

Suitable for placing inserts. The linear expansion coefficient should be small so that the connection with the inserts remains firm after temperature changes.

High dimensional stability. During specific use, the creep will be small and will not warp after being stressed, and the expansion will be small after heating. Generally, the dimensional accuracy of the hole spacing between contact parts is required to be maintained at level 6.

The processing fluidity should be good to meet the requirements of increasingly miniaturized electronic connectors.

No corrosive gases are produced

Good solvent resistance: Plastic parts should not be corroded or cracked when exposed to solvents.

No corrosive gases are produced. During the use of plastic parts, gases that are corrosive to the silver plating layer should not be produced to prevent the conductive properties of the contacts from being affected.

Challenges in Miniaturization: Connector Difficulties

In almost any product containing electronic components, miniaturization has become an eternal topic for engineers. Equipment such as automobiles, mobile devices, medical equipment, defense systems, consumer electronics, and home appliances all have one thing in common: they are shrinking in size to meet changes in market demand.

Factors such as market competition, consumer and industrial enterprise preferences, and market demand prompt designers to look for ways to reduce the size of electronic devices, components, wire harnesses, and enclosures.

At the same time, functionality needs to be continuously added to support the latest evolving technologies, but the industry faces significant challenges in meeting all of the above needs. For example, consumers don’t want mobile devices to get bigger.

Automakers need to continue to reduce the size and weight of vehicles to increase the range of traditional gas-powered cars, trucks and electric vehicles. In the medical field, wearable medical devices must become smaller and lighter to improve patient convenience.

Connector Difficulties

Electronic connectors play an important role in design: wire-to-board, wire-to-wire, board-to-board, flexible flat cable (FFC), flexible printed circuit (FPC), input/output (I/O), power and RF ( RF) connectors are part of the electrical cycle, connectors connect power and signals throughout the device and tie all the individual parts together so that they can interact successfully.

As the overall size of products shrinks, whether to simplify equipment or to make room for other critical components, connectors must also shrink. This is a real challenge for designers.

The needs of application scenarios promote the miniaturization of connectors

Mobile devices are expected to remain portable, and as technology evolves, consumers increasingly want more electronic functions. Take 5G as an example. Manufacturers are adding new antenna arrays to support 5G’s advanced features.

Likewise, semiconductors have built-in additional functionality and increased I/O requirements. However, the larger batteries needed to meet power requirements or extend operating times also present significant challenges for designers.

The same challenge arises in the automotive world, where electronic equipment such as digital cockpits and sensing capabilities have proliferated to the point where the entire wiring harness is one of the heaviest and most expensive components.

Medical patients also want smaller, more comfortable wearable devices. Whether in consumer electronics or medical devices, industrial control devices and the Internet of Things are adding more capabilities, becoming independent edge devices that can process and store data until they can transfer it back to cloud processors.

In these critical applications, connectors often become one of the main limiting factors in reducing mechanical size. Connector terminal pitch dimensions (i.e., the distance between the centers of two adjacent contacts) must be reduced to accommodate smaller circuit boards and higher pin densities to support the required I/O expansion.

Need for Innovation

Scaling down to meet user and industry demands is a challenge. However, other design constraints and requirements also exist.

Connectors often perform more than a single task in devices and also carry high-frequency signal transmission, such as 5G or other cellular and Wi-Fi communications, as well as other forms of signals and even power. Shielding becomes complex, pins need to be isolated from each other, and connectors require additional housing.

The small size of pins and contacts leaves less material to make a given connection, imposing tighter limits on the amount of signal and even power they can carry.

Smaller geometries create additional heat, and smaller-sized connections create greater resistance, so the heat must be dissipated. Components are more compactly laid out and have less space around them, which also means less space is available to guide air to cool components and connectors.

Smaller connectors result in reduced signal transmission and may increase signal loss. Selecting the correct connector type and designing it into the appropriate location on the printed circuit board can have a significant positive impact on its form factor and overall signal-to-noise performance.

Challenges facing manufacturing

If electrical design requires creative thinking, so does manufacturing engineering. There are many obstacles to miniaturizing connectors that manufacturers must learn to clear.

Connectors can be very small, which makes it difficult for people to assemble them, especially when the connectors can be as big as a grain of rice. These smaller connectors are also more fragile and can easily break if not handled properly. This makes assembly more complex and time-consuming, whether done by machines or humans.

A little too much force on the factory line can destroy not just the connector, but the entire device, significantly increasing operating costs. These challenges grow exponentially when workers on factory production lines are often required to handle thousands of connectors per day.

In addition to the fragile nature of miniaturized connectors, manufacturers have many other considerations when designing with them.

These include understanding how to repair damaged connectors, applying correct mating forces, and considering the required geometry based on the layout of the component or device. All of these manufacturing challenges make selecting the right connector partner an essential step in the design process.

How to improve the efficiency of connector assembly?

Advanced technology allows companies to design and manufacture products in different locations, promoting global business development. However, these scalability capabilities often create unique challenges that can lead to inefficiencies, especially since feature-rich electronic innovations often rely on a variety of complex wire-to-wire and wire-to-board connections.

As a result, when assembly teams need to accurately match or “mate” a miscellaneous variety of cables and connectors, the risk of costly errors and production delays can rise significantly.

In addition, it is often found that spending too much time on this delicate task can also increase the likelihood of on-the-job repetitive strain injuries and musculoskeletal problems, resulting in additional costs for manufacturers.

Matching is important

Assembly quality is one of the critical aspects of connector performance that is often overlooked. Even the most robust connectors made from top-notch materials will degrade in performance if not properly mated or installed. As a result, companies are increasingly focusing on identifying and resolving connector-related assembly issues.

The difficulty encountered with traditional connectors is that they often contain multiple functions and circuits with different purposes, while the connectors themselves are small and similar in appearance. As a result, even the most skilled assembly teams can make the following serious mistakes, especially when working in a hurry:

(1) Cross-mating – The male and female connectors of two different brands are matched or bonded together.

(2) Mismating – The male and female connectors of two connectors of the same brand are incorrectly matched or bonded together.

Cross-mating: a high-risk operation

While connectors from different brands are often very similar, cross-mating them can cause serious or even dangerous problems with intended functionality, reliability, and/or safety. As industry and application demands for power continue to increase, these potential issues must be taken seriously, especially as a wide variety of design materials become available.

There is no one-size-fits-all solution that delivers superior performance in every application, so different connector manufacturers use a wide variety of materials to build their products. Each option has certain advantages in specific situations. For example, the connector body provides mechanical and environmental protection.

A wide variety of plastics or metals can be used as materials for the connector body, depending on the intended application. Therefore, cross-mating connectors may combine two incompatible materials, which may severely impair functionality.

Wrong mating: a costly mistake

Even if the connector is made by the same manufacturer if mated incorrectly it can have a huge detrimental impact on performance, production costs and end-user safety.

Improper mating can result in signal loss, mechanical failure, equipment damage or short circuits, and can require significant time troubleshooting. The risk of assembly errors may be further increased if connector labels are printed in an unfamiliar language or are lost entirely in transit.

Keying technology is the solution

Fortunately, production teams are no longer limited to traditional connector designs. An increasing number of multi-functional connector solutions are being developed to address these significant issues. These products come in two main forms:

Colour-keyed connectors – have a bright appearance or colour-coded graphics that make it easier and faster to visually match coordinated colors and identify errors.

Understand keying and polarization

Mechanically Keyed Connectors – Uniquely shaped to fit only the corresponding connector and can only be inserted one way.

Understand keying and polarization

In addition to preventing mismatching, mechanical keying solutions also reduce the likelihood of polarization errors that can cause problems. Since polarization and keying are two very similar connector characteristics, they are often confused.

Polarization refers to one or more features of a connector pair designed to only allow mating in the correct orientation. For example, one of two connectors may be mated correctly during assembly, but the other may be incorrectly rotated 180 degrees.

Adding mechanical keying functionality physically prevents this error from occurring. Mechanical keying is especially important if the operator cannot see the connector components during assembly (a practice known as “blind mating”).

All in All:

Keying helps assembly operators quickly and accurately match/mate connectors when working with multiple similar-looking connectors. There is no need to stop and look for subtle identification marks, greatly reducing the possibility of cross-mating or mismating.

Polarization helps ensure that correctly matched connectors mate in the correct orientation. The unique shape of mechanically keyed connectors often serves as a polarizing function because the connectors can only be assembled together in one direction.

Promote design flexibility

Given these important dynamics, forward-thinking design engineers can provide significant efficiency benefits by specifying keyed connectors early in the project.

Likewise, engineers who want specific capabilities can proactively support evolving product safety and reliability needs. Keep in mind, when considering incorporating keyed connectors, that the following characteristics often help optimize long-term performance:

① As products become smaller, compact designs save valuable printed circuit board (PCB) space

② The barriers between each mating housing can reduce the arc discharge effect caused by contaminants

③ Polarizable bonds on the shell reinforcement reduce the possibility of electrical short circuits

④ The retainer helps the crimp terminal to be fully inserted to prevent moisture from entering

⑤ Pressure lock housing provides tactile and auditory feedback to help increase assembly speed

⑥Terminal secondary lock (TPA) ensures that the terminal is firmly fixed in the connector jacket to reduce electrical contact problems caused by terminal backout

⑦ Anti-snagging design enables a more efficient process

⑧ Halogen-free materials can withstand high-temperature assembly processing

⑨ Meet European Glow-Wire standards to ensure consumer safety

Support various needs of different industries

As today’s advanced product designs integrate more and more functionality into smaller and smaller spaces, connector keying technology is becoming increasingly common in a variety of industries.

Automotive, appliances, consumer products, healthcare, industrial, telecommunications, defence and many other industries require highly reliable performance, and reliable performance depends on accurate interconnects. Factors such as rough handling and harsh working conditions require proper, secure connector mating.

Additionally, as new generations of smart devices and appliances operate without constant user supervision, correct and precise connector pairing is essential to ensure safe and reliable performance. The video in this article provides an in-depth look at the various ways keyed connectors can improve efficiency in many demanding applications.

Improve efficiency to ensure safety and performance

Today’s fast-moving business environment leaves little room for error, but safe and reliable product performance remains a top priority. Color-keyed connectors and mechanical keying controls help prevent costly mating errors, simplify the assembly process, speed up production, and even improve workplace ergonomics.

When specifying keyed connectors for a specific design, intentionally selecting specific features also often helps improve the long-term functionality of the product. These innovative connection solutions represent in many ways the “key” to increased efficiency, and that’s not empty talk.

What new changes does the development of automotive intelligence bring to connectors?

Driven by the market and policies, automobile intelligence is developing rapidly. As one of the largest connector markets, what new changes will the automotive market, whose intelligence process continues to accelerate, bring to the connector industry?

The first half of the automobile “electrification” revolution is being staged fiercely, and the second half of the “intelligent” revolution has also quietly sounded.

The new energy vehicle market has developed strongly in recent years, and car companies have begun to “roll” towards intelligent network development. In early August, Musk announced on social platforms that Tesla is expected to achieve full autonomous driving by the end of the year, that is, L4 and L5 level autonomous driving.

Immediately afterwards, Toyota also announced that it would establish a joint venture with Chinese emerging company Pony AI to enter the field of self-driving taxis, to realize the practical use of self-driving taxis as early as 2024.

As my country’s automobile intelligence enters a new stage of development, favourable policies have also been introduced.

Recently, the Ministry of Industry and Information Technology and the National Standardization Committee jointly revised and issued the “Guidelines for the Construction of the National Internet of Vehicles Industry Standard System (Intelligent Connected Vehicles) (2023 Edition)” (hereinafter referred to as the “Guidelines”), which aims to combine the development status of my country’s intelligent connected automobiles.

Set up a technical logic framework of “two horizontal and three vertical” and build an intelligent and connected vehicle standard system including intelligent connected vehicle foundation, technology, products, test standards, etc.

As the “blood vessel” of the automobile assembly system, the connector plays an important role in connection and transmission. A traditional fuel vehicle requires hundreds to thousands of connectors; electric vehicles require even more connectors due to the addition of battery devices.

As one of the important markets in the connector industry, driven by new standards, the rapidly developing smart car market will usher in a new round of changes, which will undoubtedly bring new trends to connector companies.

Current status of automotive intelligence development: L2 is popularized, but L2+ still needs to leapfrog

The development of automobile intelligence is mainly divided into two aspects: “autonomous driving” and “Internet of Vehicles”. The development of autonomous driving can be divided into six stages: L0, L1, L2, L3, L4 and L5, of which L5 is fully autonomous. driving, and the Internet of Vehicles is mainly the development of “Ethernet”.

The development of autonomous driving and the Internet of Vehicles are closely related and closely connected. Whether they can move beyond L2 to L3, L4 or even L5 will be a watershed in the development of automobile intelligence.

At present, my country’s automobile intelligence is still at the stage of popularizing the application of L2-assisted driving and piloting and promoting L3 and L4-level autonomous driving.

According to data from the Gaogong Intelligent Automotive Research Institute, the number of domestic new cars equipped with forward ADAS (Advanced Driving Assistance System) will be insured for the whole year of 2021. It is 8.0789 million, a year-on-year increase of 29.51% – of which the number of new cars equipped with L2 ADAS is 395.62. million vehicles, an increase of 77.65% year-on-year. At the same time, the annual insurance volume of new L2+ ADAS vehicles has also shown a rapid increase.

New changes in connectors

New changes in connectors: Thinness, thinness and reliability are key

Perception, decision-making, and control are the three development aspects that are the core of the intelligent operation of automobiles. The path to achieving this is to detect data by the sensor system, then use algorithm technology to make decisions on the sensed information, and finally issue instructions through the control system to complete the control of the entire vehicle. control actions.

In the process from perception to control, ultrasonic radar, millimetre wave radar, cameras, GPS and other devices need to be connected, which requires relying on RF connectors and Ethernet connectors in high-speed connectors.

RF connectors mainly include Fakra connectors, Mini-Fakra connectors HSD connectors, etc., which are mainly used for the transmission of RF signals, GPS, vehicle Internet access, etc.; Ethernet connectors mainly help the electronic control units in the car communicate. transmission.

The stability and reliability of signal transmission have a direct impact on the operation of automobile intelligent systems. It can be seen that with the advancement of automobile intelligence, such as RF coaxial connectors, Mini-Fakra, floating board-to-board, and smart cockpits The development space of automotive signal end connectors such as connectors and SPE connectors is promising in the future.

With the integrated development of automation functions, sensing and decision-making functions, etc., the demand for data transmission will continue to increase, placing new requirements on the transmission frequency of RF connectors and the stability of Ethernet connector transmission.

Under the condition that the transmission rate is greatly increased, whether high-speed connectors can have higher reliability and whether they can be immune to electromagnetic influence in an all-electric high-power environment.

Also in the development of intelligent automobiles, can connector manufacturers The key is to break through the “stuck” problem and seize the opportunity.

The development of automobile intelligence means that complex intelligent hardware systems must be installed in a limited vehicle space to achieve more stable perception, decision-making, and control effects. This requires that connectors develop towards thinner, lighter and smaller sizes, while high-speed connectors that were originally large and had low transmission rates may withdraw from the market. This will also be a new round of survival of the fittest.

Just like compared with the Fakra connector, the Mini-Fakra connector has gradually occupied the market with its advantages of high transmission frequency, small size and high integration. As the number of smart car chip applications gradually increases, Ethernet connectors are also expected to replace the new differential connectors in HSD connectors.

New Trend in Connectors

New Trend in Connectors: Domestic Alternative Welcome Machines

The development of smart cars has entered the deep water zone. The country has introduced favourable policies such as the integrated development of “car energy, road and cloud”. Domestic car companies have “jumped on the news” and are planning to move towards new tracks.

In June, Li Auto officially announced that urban NOA (autonomous navigation-assisted driving) will be open for internal testing in Beijing and Shanghai, and the commuting NOA function will be opened within half a year; Xpeng Motors also announced not long ago that urban NGP (intelligent navigation Assisted driving) function has been officially opened in Beijing. At the same time, Cyrus and Avita also announced plans to launch city-level intelligent assisted driving functions.

The rise of terminal manufacturers indicates the strong momentum of my country’s automobile industry in the second half of the intelligence revolution, and indicates that Chinese automobile brands will gradually increase their voice in the second half of the track. On the fast track of smart car development, if connector companies can quickly deploy and implement industrial and technological changes, they can still create a vast world.

The rise of China’s intelligent automobile manufacturing will surely bring new opportunities for domestic substitution in the connector industry.

How to maintain

Current status of connector layout: AVIC Optoelectronics was the first to lay out electrical connection technology with remarkable results

My country’s automotive connectors started late, the market is relatively fragmented, and there is still a large gap compared with large international companies. At present, the core technology of mainstream automotive high-speed connectors is still in the hands of foreign companies.

The top global automotive high-speed connector manufacturers are mainly Japanese and American companies, including Rosenberg, Tyco, Amphenol, JAE, etc. However, domestic automotive connector manufacturers have also been catching up in recent years and achieved considerable results.

In terms of automotive high-speed connectors, the representative ones include AVIC Optoelectronics, Electrical Connection Technology, Yihua Technology, etc.

AVIC Optoelectronics is the earliest connector company involved in the field of new energy vehicles in my country. It covers the main models of domestic mainstream car companies and is committed to realizing the nationalization of vehicle-mounted high-speed connectors.

Yihua Technology also has many years of research and development experience in vehicle-mounted high-speed connectors. The vehicle-mounted high-speed connectors currently developed can meet the requirements for signal transmission of up to 12Gbps ports and are suitable for the needs of L3 electric vehicles.

Electrical Connection Technology is a leading company in micro RF connectors and has reached the same technical level as the world’s first-class connector manufacturers.

The rapid development of automobile intelligence and connectivity is spurring new changes in the connector industry. In the fast lane of automobile intelligence, which connector manufacturers can stand out in the fierce competition and achieve overtaking in corners? We will wait and see.

A brief analysis of the difference between sealed connectors and non-sealed connectors

A connector is a common component in electronic equipment that is used to connect circuits together so that current can be transmitted smoothly and ensure the normal operation of the equipment.

They are widely used in a variety of fields and offer features such as reliability, high-speed transmission, high-density connectivity and durability to support device performance and functionality.

When it comes to electrical connections in automotive and industrial environments, it’s important to understand the differences between sealed and unsealed connectors. This article focuses on the subtle differences between these two types of connectors.

Definition-and-application-scenarios

Definition and application scenarios

Sealed connectors are specially designed for electrical and signal transmission, and have sealing properties such as waterproof, dustproof, and anti-corrosion. They provide reliable connections in harsh environments and protect internal circuitry from the external environment.

Sealed connectors are widely used in automotive, aerospace, shipbuilding, military, industrial equipment, outdoor electronics and other fields. These applications have high requirements for connector sealing and reliability.

Non-sealed connectors have no sealing design, and the connectors are not specially treated to prevent liquid or dust from entering. Non-sealed connectors are usually used for internal slot connections in household appliances, IT equipment, and unimportant line connections inside automobiles. These applications do not require high protection levels and have low working environment requirements.

Functional features

Functional features

Sealing performance: Sealed connectors use special sealing materials, sealing rings or structures to prevent external substances such as water, dust and chemicals from entering the interior. This ensures reliable protection against corrosion and short circuits. Non-sealed connectors have a simpler structure and do not use sealing rings or other sealing devices, so their protective performance is low.

Protection level: Sealed connectors are waterproof, can work underwater or in humid environments, and meet specific waterproof standards, such as IP67 or IP68. Unsealed connectors have a lower level of protection and are not suitable for use in harsh environments, such as outdoors, humid or corrosive environments.

Special design: Sealed connectors usually have special connection and locking mechanisms to ensure a strong and reliable connection, so they cost more. They may contain additional sealing components such as O-rings or sealing threads. Unsealed connectors do not require these additional components and are relatively inexpensive to manufacture.

Dustproof performance: Sealed connectors effectively prevent the entry of tiny particles, dust and other impurities, preventing contamination and electrical problems at contact points. The open connector head of a non-sealed connector helps ventilation and heat dissipation and reduces efficiency reduction caused by temperature rise, so the dustproof performance is lower.

How to maintain

How to maintain?

Whether it is a sealed or unsealed connector, regular maintenance is required to ensure proper operation and extend service life.

Appearance inspection: Regularly inspect the appearance to ensure there is no damage. Sealed connectors require inspection of the condition of the plastic housing, plating, and seals, and unsealed connectors require inspection of the pins, sockets, and housing. If damage is found, repair or replace it in time.

Cleaning: Clean the connector surface regularly to remove dust, dirt, grease, etc. Use a clean cloth or cotton swab; do not use solvent-based cleaners.

Testing: Sealed connectors require regular testing of their sealing performance to ensure the protection is effective. Non-sealed connectors need to test the contact status of the connection to ensure a good connection. Testing tools such as pressure testers or multimeters can be used for these tests.

In addition, please pay attention to the following points when using:

• Proper installation: Follow the correct steps to install the connector to ensure proper operation.
• Avoid overloading: Connectors cannot withstand excessive current or voltage to avoid damage.
• Periodic inspection: Check the connector regularly to ensure normal operation.

In summary, sealed and unsealed connectors have different uses in automotive and industrial applications, with sealed connectors providing environmental protection while unsealed connectors are used in less demanding conditions. Connector selection depends on specific application requirements.

Connector Industry Forecast to 2024

Pandemic-era supply chain disruptions and demand imbalances a year ago continue to weigh on the connector industry. These factors have improved as we enter 2024, but new technology trends and other uncertainties are changing the landscape. Here’s what to expect in the coming months.

Entering the new year, the connector industry is facing a series of challenges and opportunities. Global conflicts are putting pressure on supply chains when it comes to accessing materials and opening shipping lanes.

Labor shortages continue to impact manufacturing, especially in North America and Europe. However, demand is strong in many markets. The implementation of 5G and sustainable energy infrastructure is creating new opportunities.

Investing in chip manufacturing will soon bring new facilities into operation. The continuous development of new technologies is driving innovation in the interconnection field, and in turn, these new connector products are also achieving greater achievements in electronic design.

Connector Industry Forecast to 2024

Impact in 2024 five major trends in connectors

SWaP

It is the top priority for connector design and specification in every industry. Product design has achieved astonishing size reductions and performance leaps in high-speed interconnects, thanks to the contributions of component designers. The widespread use of portable, connected devices is transforming every product category and, over time, the way we live our lives.

In addition to small devices, large products such as cars, spacecraft and aircraft also benefit from this miniaturization trend. Smaller, lighter components not only help reduce payload but also open up the possibility of travelling farther and faster.

Customization

While the long development time and high cost of custom components prompted the emergence of a thousand standardized, superior multi-function COTS components, new processes such as digital modeling, 3D printing and rapid prototyping allow designers to quickly and Get perfect, uniquely designed parts without too much of an expensive burden.

Advanced packaging enables designers to push the limits of Moore’s Law, replacing traditional integrated circuit designs with new strategies that integrate chips, and electrical and mechanical components into a single packaged device. Multi-chip modules, system-in-package (SIP), 3D IC, and other creative packaging designs are enabling huge performance improvements.

New material

Materials science is addressing market-specific needs and industry-wide challenges, including weight reduction, reinforcement and durability; biocompatibility and sterilization requirements, and the need for products that are safer for the environment and human health.

Artificial intelligence AI

AI technology is making a splash in 2023 with the arrival of generative AI models. In 2024, the technology will be applied to component design to optimize performance, increase efficiency, test systems and designs, and explore new formats.

At the same time, the extreme demand for high-speed performance required to facilitate these functions will put greater pressure on the connector industry to create new and more powerful products.

Forecasts for 2024 mixed

Forecasting is always difficult, especially in times of financial and geopolitical uncertainty. Predicting future business conditions in this environment is nearly impossible. The economic market remains unstable after the epidemic.The GDP growth rate of all economies around the world is slowing down, and the problem of labor shortage still exists.

Although shipping and trucking Increased freight capacity has led to significant improvements in global supply chain issues, but we still face some obstacles posed by labor shortages and global conflicts. Even so, the global economy appears to be performing better in 2023 than most economists expected, setting the stage for strong economic development in 2024.

Bishop & Associates expects positive connector growth in 2024. Growth in low to mid-single digits is the historical norm for the connector industry, with demand experiencing a historic rebound after a year of decline.

Report investigation

Asian companies are reporting a very pessimistic outlook. Global connector sales will remain essentially flat in 2023, although a surge in activity toward the end of the year could signal an improvement in 2024. Bookings for November 2023 are up 8.5%, November’s book-to-bill ratio is 1.00, YTD is 0.98, and the industry backlog is 13.4 weeks.

The market-leading this growth was transportation, with year-on-year growth of 17.2%; automotive followed with 14.6%, and industrial with 8.5%. Orders increased year-on-year in four of the six regions, with China experiencing the fastest growth. Even so, all regions continue to post negative results year-to-date.

Bishop’s Connector Industry Forecast 2023-2028 report provides an in-depth look at the connector industry’s performance going back throughout the pandemic recovery period, including a full report in 2022, a preliminary assessment in 2023, and a 2024 through 2028 detailed forecast. You can learn a lot about the electronics industry by looking at connector sales by market, region, and product type.

Observation Display

Europe ranks fourth among the six regions for percentage growth in 2022, but ranks first in 2023, with projected growth of 2.5%.

Sales of electronic connectors vary by market segment. The telecom/datacom market will register the largest percentage growth at 9.4% in 2022, driven by increased internet activity and the continued push for 5G. In 2023, the telecom/datacom market will again show the largest growth, growing by 0.8%, although nowhere near the growth seen in 2022.

In 2023, the telecom data communications market will be followed by the military aerospace market with a growth of 0.6%. The military/aerospace market hasn’t moved beyond key markets like automotive and industrial since 2019, but unfortunately, global turmoil has put military/aerospace spending in the spotlight.

Revealing connector insertion and extraction force: influencing factors and practical tips

The connector serves as a crucial component for transmitting signals and electrical energy, finding extensive applications in electronic devices, household appliances, automobiles, communication systems, and various other domains.

The insertion and withdrawal force stand as pivotal metrics for assessing connector performance. Consequently, it prompts the inquiry: What elements influence the plugging and unplugging forces of the connector?

The connector serves as a crucial component for transmitting signals and electrical energy, finding extensive applications in electronic devices, household appliances, automobiles, communication systems, and various other domains. The insertion and withdrawal force stand as pivotal metrics for assessing connector performance. Consequently, it prompts the inquiry: What elements influence the plugging and unplugging forces of the connector?

Factors affecting connector insertion and extraction force

Material selection

The composition of a connector material plays a substantial role in determining its mating and unmating forces. In broad terms, metal materials tend to exhibit higher hardness and strength, resulting in increased plug-in and pull-out forces for the connector.

Conversely, non-metallic materials like plastics typically have lower hardness, leading to comparatively smaller plug-in and pull-out forces. When choosing materials, a careful balance must be struck, considering specific application scenarios and performance criteria.

Design structure

The structural design of the connector also affects the mating and uniting force. For example, a connector with a threaded connection needs to overcome the friction of the threads when disassembling;

While a snap-on connector needs to overcome the friction between the slots. Structural parameters should be fully considered during design to achieve appropriate insertion and extraction forces.

Contact resistance

During the plugging and unplugging process of the connector, the contact resistance will change, thus affecting the plugging and unplugging force. The greater the contact resistance, the greater the insertion and extraction force.

Therefore, when designing and using connectors, contact resistance should be reduced as much as possible to improve plugging and unplugging performance.

Environmental factors

Environmental factors, such as temperature, humidity, dust, etc., can also affect the plugging and unplugging force of the connector. High temperature will reduce the elasticity of the connector and reduce the plug-in and pull-out force;

In an environment with high humidity, a conductive film may form on the surface of the connector, increasing the contact resistance, and thereby affecting the plug-in and pull-out force.

Number of plugging and unplugging

The number of times a connector is plugged and unplugged has a significant impact on its plugging and unplugging force. As the number of plugs and pulls increases, factors such as material fatigue and contact wear of the connector will cause the plug and pull force to gradually decrease.

Therefore, in practical applications, the number of plugging and unplugging times of the connector should be controlled to extend its service life.

Practical tips for improving connector insertion and extraction force

Choose high-quality materials

Choosing materials with high strength and low friction coefficient can improve the plug-in and pull-out force of the connector. In addition, material surface treatment, such as gold plating, spraying, etc., can be used to reduce contact resistance and improve plugging and unplugging performance.

Optimize design structure

In connector design, structural parameters, such as contact area, thread specifications, etc., should be fully considered to achieve appropriate insertion and extraction force. At the same time, automatic fastening, spring-assisted and other structures can be used to reduce the insertion and extraction force and improve the convenience of use.

Control contact resistance

The contact resistance of the connector directly affects the insertion and extraction force. Therefore, during the design and production process, contact resistance should be strictly controlled to ensure its stability during use.

Pay attention to environmental protection

Connectors should be protected from environmental factors during use. For example, in high-temperature and humid environments, auxiliary equipment such as radiators and moisture-proof covers can be used to reduce the impact of the environment on the connector.

Connector plug-in and pull-out force

Reasonably control the number of plugging and unplugging

To extend the service life of the connector, the number of plugging and unplugging should be reasonably controlled. In practical applications, modular design can be used to reduce the frequency of connector use, thereby reducing the impact of plugging and unplugging forces on the connector.

The connector plug-in and pull-out force are affected by many factors. By selecting high-quality materials, optimizing the design structure, controlling contact resistance, paying attention to environmental protection and rationally controlling the number of plug-in and pull-out times, the plug-in and pull-out performance of the connector can be effectively improved.

 

A brief analysis of the differences between terminal blocks, connectors and connectors

The usage range, functions and application fields of terminal blocks, connectors and connectors are as follows:

What new changes does the development of automotive intelligence bring to connectors?

Driven by the market and policies, automobile intelligence is developing rapidly. As one of the largest markets for connectors, what new changes will the automotive market, whose intelligence process continues to accelerate, bring to the connector industry?

The first half of the automobile “electrification” revolution is being staged fiercely, and the second half of the “intelligent” revolution has also quietly sounded.

In recent years, the new energy vehicle market has developed strongly, and car companies have begun to “roll” towards intelligent network development. In early August, Musk announced on social platforms that Tesla is expected to achieve full autonomous driving by the end of the year, that is, L4 and L5 level autonomous driving. Immediately afterwards, Toyota also announced that it would establish a joint venture with Chinese emerging company Pony AI to enter the field of self-driving taxis, with the goal of realizing the practical use of self-driving taxis as early as 2024.

As my country’s automobile intelligence enters a new stage of development, favourable policies have also been introduced. Recently, the Ministry of Industry and Information Technology and the National Standardization Committee jointly revised and issued the “Guidelines for the Construction of the National Internet of Vehicles Industry Standard System (Intelligent Connected Vehicles) (2023 Edition)” (hereinafter referred to as the “Guidelines”), aiming to combine the development status of my country’s intelligent networked automobiles. Set up a technical logic framework of “two horizontal and three vertical” and build an intelligent and connected vehicle standard system including the basis, technology, products, test standards, etc. of intelligent and connected vehicles.

As the “blood vessel” of the automobile assembly system, the connector plays an important role in connection and transmission. A traditional fuel vehicle requires hundreds to thousands of connectors; electric vehicles require even more connectors due to the addition of battery devices. As one of the important markets in the connector industry, driven by new standards, the rapidly developing smart car market will usher in a new round of changes, which will undoubtedly bring new trends to connector companies.

Current status of automotive intelligence development

L2 is popularized, L2+ still needs to leapfrog

The development of automobile intelligence is mainly divided into two aspects: “autonomous driving” and “Internet of Vehicles”. The development of autonomous driving can be divided into six stages: L0, L1, L2, L3, L4 and L5, of which L5 is truly fully autonomous. driving, and the Internet of Vehicles is mainly the development of “Ethernet”. The development of autonomous driving and the Internet of Vehicles are closely related and closely connected. Whether they can advance from L2 to L3, L4 or even L5 will be a watershed in the development of automobile intelligence.

At present, my country’s automobile intelligence is still at the stage of popularizing the application of L2-assisted driving and piloting and promoting L3 and L4-level autonomous driving. According to data from the Gaogong Intelligent Automobile Research Institute, the number of domestic new cars equipped with forward ADAS (Advanced Driving Assistance System) in 2021 will be 8.0789 million, a year-on-year increase of 29.51% – of which the number of new cars equipped with L2 ADAS will be 395.62 million vehicles, an increase of 77.65% year-on-year. At the same time, the annual insurance volume of new L2+ ADAS vehicles has also shown a rapid increase.

New changes in connectors

New changes in connectors

Thinness, thinness and reliability are key

Perception, decision-making, and control are the three development aspects that are the core of the intelligent operation of automobiles. The path to achieving this is to detect data by the sensor system, then use algorithm technology to make decisions on the sensed information, and finally issue instructions through the control system to complete the control of the entire vehicle. control actions.

In the process from perception to control, ultrasonic radar, millimetre wave radar, cameras, GPS and other devices need to be connected, which requires relying on RF connectors and Ethernet connectors in high-speed connectors. RF connectors mainly include Fakra connectors, Mini-Fakra connectors HSD connectors, etc., which are mainly used for the transmission of RF signals, GPS, vehicle Internet access, etc.; Ethernet connectors mainly help the electronic control units in the car communicate. transmission.

The stability and reliability of signal transmission have a direct impact on the operation of automobile intelligent systems. It can be seen that with the advancement of automobile intelligence, such as RF coaxial connectors, Mini-Fakra, floating board-to-board, and smart cockpits The development space of automotive signal end connectors such as connectors and SPE connectors is promising in the future.

With the integrated development of automation functions, sensing and decision-making functions, etc., the demand for data transmission will continue to increase, placing new requirements on the transmission frequency of RF connectors and the stability of Ethernet connector transmission. Under the condition that the transmission rate is greatly increased, whether high-speed connectors can have higher reliability and whether they can be immune to electromagnetic influence in an all-electric high-power environment. Also in the development of intelligent automobiles, can connector manufacturers The key is to break through the “stuck” problem and seize the opportunity.

The development of automobile intelligence means that complex intelligent hardware systems must be installed in a limited vehicle space to achieve more stable perception, decision-making, and control effects. This requires that connectors must develop towards thinner, lighter and smaller sizes. High-speed connectors that were originally large in size and had low transmission rates may be withdrawn from the market. This will also be a new round of survival of the fittest.

Just like compared with the Fakra connector, the Mini-Fakra connector has gradually occupied the market with its advantages of high transmission frequency, small size and high integration. As the number of smart car chip applications gradually increases, Ethernet connectors are also expected to replace the new differential connectors in HSD connectors.

Car connector industry chain

New Trend in Connectors: Domestic Alternative Welcome Machines

The development of smart cars has entered the deep water zone. The country has introduced favorable policies such as the integrated development of “car energy, road and cloud”. Domestic car companies have “judged the trend” and are planning to move towards new tracks.

In June, Li Auto officially announced that urban NOA (autonomous navigation-assisted driving) will be open for internal testing in Beijing and Shanghai, and the commuting NOA function will be opened within half a year; Xpeng Motors also announced not long ago that urban NGP (intelligent navigation Assisted driving) function has been officially opened in Beijing. At the same time, Cyrus and Avita also announced plans to launch city-level intelligent assisted driving functions.

the connector industry

The rise of terminal manufacturers indicates the strong momentum of my country’s automobile industry in the second half of the intelligent revolution and indicates that Chinese automobile brands will gradually increase their voice in the second half of the track. On the fast lane of smart car development, if connector companies can quickly deploy and implement industrial and technological changes, they can still create a vast world.

The rise of China’s intelligent automobile manufacturing will surely bring new opportunities for domestic substitution in the connector industry.
