What is the role of automotive wiring harness?

Automotive wiring harness is the basic carrier of automobile internal communication, and automotive wiring harness is the main body of automobile circuit network, which connects automobile electrical and electronic components and makes them play a role. Without wiring harness, there would be no car circuit. Automotive wiring harness is a contact terminal made of copper, which is crimped by wires and cables, and then an insulator or a metal shell is pressed on the outside, which is bundled with the wiring harness to form an assembly for connecting circuits. At present, whether it is a luxury car or an economical ordinary car, the wiring harness is basically the same form, consisting of wires, plug-ins and packaging belts. It is necessary to ensure not only the transmission of electrical signals, but also the reliability of connecting circuits, provide specified current values for electronic and electrical components, prevent electromagnetic interference to surrounding circuits, and eliminate electrical short circuits.
