Automotive Wire Harness Industry Survey
Automotive wire harnesses are the network body of automotive circuits. Automotive wire harnesses are mainly composed of wires, terminals, connectors, and sheaths. The specific process is to crimp the contact terminals (connectors) punched from copper material onto the cable, then press the insulation with plastic or add a metal shell, and then bind it with the wire harness to become a part for circuit connection. Automotive wire harness products are customized products, and the design plans and quality standards vary depending on the OEM and model. Automotive wire harnesses are responsible for the energy and various signal transmission of automobiles, and connect the central control components with the automobile control unit, electronic and electrical execution units, and electrical equipment to form the electronic control system of automobiles, which is the blood vessels and nerves. Automotive system.
Classification of automotive wire harness: 1) When classified by function, wire harnesses can be divided into power lines and signal lines. Power lines are thicker and are mainly used to transmit electric current; signal lines are multi-core flexible wires made of copper, mainly used to transmit electrical signals. 2) According to the layout inside the car, wire harnesses can be divided into body assembly wire harness, engine wire harness, instrument panel wire harness, chassis wire harness, ceiling wire harness, door wire harness, etc.
