Design of automotive wiring harness
The role of wiring harness in the vehicle is to transfer or exchange the power signal or data signal of the electrical system to achieve the functions and requirements of the electrical system.
Wiring harness design process and manufacturing process
(1) The electrical layout engineer shall provide the function, electrical load and related special requirements of the vehicle electrical system. The status, installation position, and connection form between wiring harness and electrical appliance.
(2) According to the electrical functions and requirements, draw the electrical schematic diagram and circuit diagram of the vehicle.
(3) According to the electrical principle circle for each electrical subsystem and loop energy distribution, including power supply wire, and ground point distribution.
4) According to the distribution of electrical components of each subsystem, determine the wiring form of the wiring harness, the electrical components connected by each wire harness and the direction of the car; Determine the external protection form of the wire harness and the protection of the hole; Determine fuses or circuit breakers according to electrical load; Recolour; Determine the type of terminal and sheath to be connected to the electrical component based on the connector of the electrical component.
