What are the design processes and manufacturing processes for automotive wiring harnesses?

The role of automotive wiring harness in the whole car is to transfer or exchange power signals or data signals of the electrical system to realize the functions and requirements of the electrical system. It is the main body of the network of the automobile circuit, and there is no automobile circuit without the wiring harness. Automotive wiring harness design process and manufacturing process is more complex, requiring wiring harness engineers careful and meticulous, can not have a little sloppy. If the wiring harness design is not good, can not be combined with the function of each part of the organic, it is possible to make the wiring harness to become the automobile faults of multiple links.

I. What are the design process and manufacturing process of automotive wiring harness?1. Firstly, the electrical layout engineer will provide the function of the electrical system of the whole vehicle, the electrical load and related special requirements. The state of electrical parts, installation location, wiring harness and electrical parts of the form of docking. 2. According to the electrical function and requirements provided by the electrical layout engineer, you can draw the entire vehicle electrical schematic diagram and wiring diagram. 3. 3. According to the electrical schematic circle for each electrical subsystem and circuit energy allocation, including power supply lap wire, and grounding point allocation. 4. According to the distribution of electrical parts of each subsystem, determine the wiring form of the wiring harness, each wiring harness connected to the electrical parts and the direction of the car; to determine the form of external protection of the wiring harness and the protection of the over-hole; according to the electrical load to determine the fuse or circuit breaker; and then according to the amount of fuses or circuit breakers to determine the wire diameter; according to the function of the electrical parts, according to the relevant standards to determine the wire color; according to the electrical parts themselves According to the function of the electrical components to determine the wire color; according to the electrical components of their own connectors to determine the wiring harness with the terminal and the type of sheath. 5. Draw two-dimensional wiring harness diagrams and three-dimensional wiring harness layout. 6. According to the approved three-dimensional wiring harness layout, check the two-dimensional wiring harness diagram, two-dimensional wiring harness diagram is accurate before sending the map, after approval, according to the wiring harness diagram trial production, production.
