How Much Do You Know About The Car Wiring Harness?

The car wiring harness is the main body of the car circuit, and there is no car circuit without the wire harness. The wire harness refers to a component that is made of a copper material and is crimped to the wire and cable, and then externally molded with an insulator or a metal casing, and bundled with a wire harness to form a component of the connecting circuit.

Automotive wires are also called low-voltage wires, which are different from ordinary household wires. Ordinary household wires are copper single-core wires with a certain hardness. The car wires are all copper multi-core soft wires, some soft wires are as thin as hair, and several or even dozens of soft copper wires are wrapped in plastic insulating tubes, which are soft and not easy to break.

Due to the particularity of the automotive industry, the manufacturing process of automotive wiring harnesses is also more special than other common wiring harnesses.

Wires in automotive wiring harnesses are commonly used with wires with a nominal cross-sectional area of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0, etc. (the nominal cross-sectional area commonly used in Japanese cars is 0.5, 0.85, 1.25, 2.0). , 2.5, 4.0, 6.0, etc. square millimeters), each of which has a allowable load current value, which is used for wires of different power consumers.

The wire harness is wrapped with a woven thread or a plastic tape. For safety, processing and maintenance, the woven wire package has been eliminated. It is now wrapped with viscous plastic tape. The connection between the harness and the harness, between the harness and the electrical component, using a connector or a wire ear. The connector is made of plastic and has a plug and socket. The wire harness and the wire harness are connected by a plug-in, and the connection between the wire harness and the electrical component is connected by a plug or a wire ear.
