​How to choose car wiring harness

In automotive parts, the role of automotive wiring harnesses is very important. This is the key to driving a car, so buying a good car harness is a must.

How to choose car wiring harness


Wires come in a variety of sizes, and the current values for each type of load vary, for wires used in devices with different power. The wires of the car are basically copper multi-core cords, and the outer layers of the wires are wrapped with plastic insulating tubes, which can effectively ensure that the wires are soft and not easily broken.


The connector is selected to ensure good contact with the electrical components, minimize contact resistance and improve reliability. For example, when designing the connector, different sheath materials can be selected according to different requirements. Flame retardant or reinforcing materials should be added to the plastic according to the actual situation to achieve the purpose of strengthening or flame retarding. In terms of terminal materials, the copper used for the connectors is mainly brass and bronze (the hardness of brass is slightly lower than that of bronze), in which brass accounts for a large proportion. In addition, different coatings can be selected according to different needs.

Wrap tape

The way to wrap the tape is for the convenience of safety, processing and maintenance. Currently, the wire harness is basically wrapped with a plastic tape. The purpose of the wrapping tape is to protect the product with casing and tape, which is resistant to abrasion, high temperature, flame retardant, corrosion, interference, noise reduction and beautification.
