How to buy auto connector wiring harness

How to buy auto connector wiring harness

Blog | Jan 28,2022

If you currently need to purchase automotive terminal harness products, or in the future also need to understand the relevant procurement knowledge, let us introduce how to buy for you.

What materials are available

First of all, we need to understand what the material of the car terminal wire harness is, generally aluminium and copper. The difference is that aluminium is lighter but less durable, while copper is heavier but more durable. Depending on the application you need and the appropriate current intensity, some devices may only use terminal wires made of one material.

What materials are available

What types of insulation are available

Automotive terminal wires can often be made of PVC insulation or “crosslinked” insulation because the material is extruded under heat and pressure, changing the molecular structure and allowing it to withstand higher temperatures. Crosslinked insulation is generally more durable, while PVC insulation will be more cost-effective.

Fully understand the electrical wiring used in the equipment. Because cross-linked wires should be used for extremely high-temperature applications such as engine nacelles, PVC insulated wires can be used for general applications.

Which welding method should be selected

Terminals usually have two types of connections, welding and non-welding. The weldless connection quickly disconnects terminals and connectors. This means that for all applications, weldless connections are not too strong, and although weldless connections take longer to complete, they provide a strong connection.

Which welding method should be selected

Cable selection

The longer the wire is required for general applications, the more current needs to flow, the lower the wire specifications. Before purchase, the required terminal cable parameters and specifications should be clear. It is recommended to check the thicker wire side as far as possible to avoid inferior products.
