How to solve the problem of weak terminal wiring? Try these methods!

In automobiles or other mechanical equipment, terminal blocks are key components for connecting electrical components and circuits. If the wiring of terminal blocks is not firm, it may cause circuit failure or damage to electrical components. This article will introduce how to solve the problem of weak wiring of terminal blocks.

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.
