What are the principles of automotive wiring harness design?

Automotive wiring harness is the main body of the network of automotive circuits, there is no wiring harness there is no automotive circuit. As people's safety, comfort, economy and emission requirements of automobiles improve, the electrical configuration of the car, the function is also more and more, so the wiring harness connecting the various electrical parts is also more and more complex, and has become a contemporary automobile failures of the frequent links, but also in the automobile design and manufacturing by more and more attention. How to improve the comprehensive performance of the automotive wiring harness has become the focus of attention, increase and automobile OEM joint pre-development has become an inevitable trend. The role of automotive wiring harness in the vehicle is to transfer or exchange power signals or data signals of the electrical system to realize the functions and requirements of the electrical system.

The design process and manufacturing process of automotive wiring harness (1) The function of the electrical system of the whole vehicle, electrical load and related special requirements are provided by the electrical layout engineer. The state of electrical parts, installation location, and the form of wiring harness and electrical parts docking. (2) According to the electrical function and requirements, draw the electrical schematic diagram and wiring diagram of the whole vehicle. (3) According to the electrical principle circle for each electrical subsystem and circuit energy allocation, which includes the power supply of the hitch line, as well as the allocation of grounding points. (4) According to the distribution of the electrical parts of each subsystem, determine the wiring form of the wiring harness, the electrical parts connected to each wiring harness and the direction of the wiring harness in the car; determine the form of the external protection of the wiring harness of the car and the protection of the over-hole; determine the fuse or circuit breaker according to the electrical load; re-color; and according to the connector of the electrical parts themselves to determine the type of the terminals and sheaths on the wiring harness that are connected to them.
