Automotive Wiring Connectors

Automobile wiring harness is the network main body of automobile circuit. Without wiring harness, there would be no automobile circuit. At present, whether it is a high-end luxury car or an economical ordinary car, the form of wiring harness is basically the same. They all have wires and connections. Consists of inserts and wrapping tape. Car wires, also called low-voltage wires, are different from ordinary household wires. Ordinary household wires are copper single-core wires, which have a certain hardness. Automotive wires are all made of copper polycore soft wires, some of which are as thin as hair. Several or even dozens of soft copper wires are wrapped in plastic insulating tubes (polyethylene), which are soft and not easy to break. Common specifications for 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. Each of them has an allowable load current value and is used for electrical equipment of different powers. of wires.

Take the vehicle wiring harness as an example,

0.5 gauge wire is suitable for instrument lights, indicator lights, door lights, ceiling lights, etc.

0.75 gauge wire is suitable for license plate lights, front and rear small lights, brake lights, etc.:

1.0 specification line is suitable for turn signals, fog lights, etc.;

1.5 gauge wire is suitable for headlights, speakers, etc.:

Main power lines such as generator armature wires, ground wires, etc. require 2.5 to 4 square millimeter wires. This only refers to ordinary cars. The key depends on the maximum current value of the load. For example, the battery's ground wire and positive power wire are specially Most automobile wires are used alone. Their wire diameters are relatively large, at least more than ten square millimeters. These large and thick wires will not be included in the main automobile wiring harness. Can only be used alone.
