In automotive circuit design, certain principles must be followed. When selecting the wire, select the wire that matches the color to avoid identifying the error. At the same time, to select the appropriate cross-sectional product, and on this basis, it is required that the wires be connected in the shortest way, and the wires should be installed on both sides of the connector for the overall automotive wire harness design. This is the basic principle of wire harness design.
Based on the relevant basic wood principles, the basic design of the automotive wiring harness is carried out. The basic flow of the main process is to first determine the electrical performance of the overall car, after the familiar, draw the electrical schematic diagram, the main design of the automotive wiring harness in the schematic diagram, pay attention to the selection of wires, terminals and connections in the design of automotive wiring harness Selection of pieces.
After the approximate design of the automobile wiring harness, the automobile is checked for reliability and tested. If the inspection is qualified, the wiring harness diagram of the automobile is further drawn, and then the automotive wiring harness process design is carried out according to the wiring harness diagram of the automobile and further put into the production of the automobile wiring harness. If the inspection fails, it is necessary to redesign the automotive wiring harness. After the design is completed, further inspection and testing of reliability will be carried out.
