What is the role of the car wiring harness?- Jijin Industral Co., Ltd.

The function of the automobile wiring harness is to press the contact terminal (connector) made of copper material with the wire and cable, then mold the insulator or metal shell to the outside, and bundle the components connected to the circuit with the Cable tie for automotive wire harness.

Automotive wires, also called low-voltage wires, are different from ordinary household wires. Ordinary household wires are copper single-core wires with a certain hardness. Automobile wires are all copper multi-core flexible wires, some as thin as hair, and several or even dozens of soft copper wires are wrapped in plastic insulating pipes (PVC), which are relatively soft and not easy to break.

With the increase of automobile functions and the wide application of electronic control technology, there are more and more electrical components and wires, and the wiring harness is also becoming thicker and heavier. Therefore, advanced automobiles have introduced CAN bus configuration, using multiplexing systems. Compared to traditional wiring harnesses, the multiplexer greatly reduces the number of wires and connectors, making wiring easier.

The wire specifications commonly used in automotive wiring harnesses include nominal cross-sectional areas of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0 and 6.0 square millimeters (the nominal cross-sectional areas commonly used in Japanese automobiles are 0.5, 0.85, 1.25, 2.0, 2.5, 4.0 and 6.0 mm²) wires
