Work flow of automotive wiring harness
1. The automobile wiring harness is the main body of the automobile circuit network, and there is no automobile circuit without the wiring harness. The wire harness refers to the touch terminal made of copper material. After crimping with the wire and cable, the plastic pressure insulator or metal shell is added to the outside, and the wire harness is bundled to form the components of the connecting circuit.
2. Automobile wiring harness is the wiring of the car interior and the body, the wiring harness planning from the body to the front and rear lights, the wiring harness planning from the engine and the chassis to the respective ECU, and the wiring harness planning from the control panel to the ECU. The repair profession does not have this position, and there is a large-scale car assembly workshop. It is responsible for the planning and equipment of the bus bundle.
3. Automobile wires are also called low-voltage wires, which are different from ordinary household wires. General household wires are copper single-core wires, which have certain hardness. The automobile wires are all copper multi-core cords. Some cords are as thin as hair. Several or even dozens of flexible copper wires are wrapped in a plastic insulating tube (polyvinyl chloride), which is soft and not easy to break.
4. With the addition of automobile functions and the widespread use of electronic control skills, there are more and more electrical parts and more and more wires, and the wiring harness becomes thicker and heavier. Therefore, advanced cars have introduced CAN bus equipment and selected multiple transmission systems. Compared with the traditional wiring harness, the multiplex transmission equipment greatly reduces the number of wires and connectors, making the wiring easier.
5. As people have higher and higher requirements for the safety, comfort and economy of automobiles, there are more and more electrical equipment and functions in automobiles, so the wiring harnesses connecting various electrical equipment are becoming more and more messy. The frequent occurrence of automobile problems in this world has received more and more attention in automobile planning and production.
