What are the basic information of automotive wire harness welding

Automotive wiring harness welding

It is the carrier of the communication of the components of the car circuit, someone once made an image metaphor, the car wire harness welding is a blood vessel, the car engine is the heart, the heart beats because of the blood vessel, the engine runs because of the wire harness welding of the car can be seen that the car wire harness is the importance of the normal stability of the car circuit. Therefore, it is necessary to understand the product and process knowledge of car wiring harness.

Wire harness refers to the component of the connection circuit that is bound by wire harness after the touch piece terminal (adapter) made of copper is crimped with the wire and cable, and then molded and pressed the insulator or the metal shell outside. In short, it is the wiring that connects the car electrical appliances, and the operating conditions and parameters of the car are reflected in the car computer through the wiring harness. On the other hand, the electronic technical content of the wiring harness of the car has become an important purpose for evaluating the function of the car.

Car wiring harness welding classification Car wiring harness can be divided into main harness and small harness two kinds. The main harness includes starter harness, center harness, instrument panel harness, cabin harness, etc. The small wiring harness includes door wiring harness, battery wiring harness, ABS brake wire harness and so on. In addition, according to the voltage difference, car wiring harnesses can be divided into high-voltage wiring harnesses and low-voltage wiring harnesses. The characteristics of high voltage lines are high voltage and low current, and the insulation function is high, so the insulation layer is often thicker and the core wire is thinner.
