What's a wire harness?

Posted On:2018-01-06 9:11:38

Car wire harness is the main body of the network of car circuits. There is no car circuit without wire harness. The wire beam refers to a contact element terminal(connector) made of copper material that is pressed with a wire cable, and the outside is then plasticized to an insulator or an additional metal shell, etc., and is bound by a wire bundle to form a connecting circuit component. The wire beam industry chain includes wire cables, connectors, processing equipment, wire beam manufacturing and downstream application industries. The wire beam application is very extensive and can be used in automobiles, household appliances, computer and communication equipment, various electronic instruments, etc.. The body wire beam connects the entire body., The general shape is H-shaped.
Car wires, also known as low-voltage wires, are not the same as ordinary household wires. Ordinary household wires are copper single-core wires with a certain hardness. The car wires are copper multi-core soft lines, some soft lines such as hair, several or even dozens of soft copper wires wrapped in plastic insulated pipes(polyvinyl chloride), soft and not easily broken. Due to the particularity of the automobile industry, the manufacturing process of automobile wire harness is also more special than other ordinary wire harness.
The system for manufacturing car wire bundles is roughly divided into two categories:
1, divided into European and American countries, including China: use the TS 16949 system to control the manufacturing process.
Mainly Japanese: Toyota, Honda, they have their own system to control the manufacturing process.
With the increase of automotive functions, the universal application of electronic control technology, more and more electrical parts, more and more wires, the more thick the wire beam becomes. Therefore, advanced cars have introduced CAN bus configuration and use a multi-channel transmission system. Compared with the traditional wire beam, the multi-channel transmission device greatly reduces the number of wires and connectors, making the wiring easier.
