The automobile Wiring Harness is the network main body of the automobile circuit, and there is no automobile circuit without the wiring harness. Wire Harness refers to the contact terminal (connector) punched from copper material and the wire and cable after being crimped, and then the outside is molded with an insulator or an external metal shell, etc., and the wire harness is bundled to form a component that connects the circuit. The wiring harness industry chain includes wires and cables, Connectors, processing equipment, wiring harness manufacturing and downstream application industries. The wiring harness is widely used and can be used in automobiles, household appliances, computer and communication equipment, various electronic instruments and meters, etc.

The body wiring harness connects the entire body , the general shape is H-shaped.Automobile 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 (polyvinyl chloride), 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.

Common specifications of wires in automobile wiring harnesses include wires with nominal cross-sectional areas of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0 and other square millimeters (the nominal cross-sectional areas commonly used in Japanese cars are 0.5, 0.85, 1.25, 2.0 , 2.5, 4.0, 6.0, etc. square millimeters), each of which has an allowable load current value, and is used for wires of different power electrical equipment. Taking the whole vehicle wiring harness as an example, the 0.5 specification line is suitable for instrument lights, indicator lights, door lights, dome lights, etc.; the 0.75 specification line is suitable for license plate lights, front and rear small lights, brake lights, etc.; Lights, etc.; 1.5 gauge wire is suitable for headlights, horns, etc.; main power lines such as generator armature wire, ground wire, etc. require 2.5 to 4 square millimeters of wire.

This only refers to the general car, the key depends on the maximum current value of the load. For example, the ground wire of the battery and the positive power wire are dedicated car wires used alone. Their wire diameters are relatively large, at least a dozen square millimeters. Above, these "Big Mac" wires will not be woven into the main harness.
