What is the auto wire harness? Mar 30, 2023

The auto wire harnesses is the network main body of the automotive circuit, and there is no car circuit without wire harnesses. The cable harness refers to the connection between the contact parts (connectors) and the wire and cable that is made of copper materials, and then plasticine the insulator or the metal connector on the outside to form a component of the connection circuit with a wire bundle. The car wire harness is divided from the function. There are two types of power cables and signal wires of the power cable of the carrier -driven execution component (as the actioner) power. Then find people's continuous improvement of comfort, economy, and safety, the types of electronic products on cars are also increasing, car wire bundles are becoming more and more complicated, and the failure rate of the deadlines also increases accordingly.


Auto wire

Auto wires are also known as low -voltage wires, which are different from ordinary household wires. Ordinary home wires are copper multi -core soft wires. Some soft wires are as thin as hair. Several or even dozens of soft copper wires are wrapped in plastic insulating tubes (polyvinyl chloride), soft but not easy to break. Due to the particularity of the automotive industry, the manufacturing process of automobile wiring is also more special than other ordinary wire assemblies.


Universal Auto Wire

The common specifications of the wires in the car wires are nominal cross -sectional area of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0 and other square millimeters (the named cutting area commonly used in Japanese cars is 0.5, 0.85, 1.25, 2.0 2.0 , 2.5, 4.0, 6.0 and other square millimeters), each of them allows the load current value to be equipped with a wire with different power equipment. Taking the entire car cable as an example, 0.5 specifications are suitable for instrument lights, indicators, door lights, top lights, etc.; 0.75 specification wires are suitable for license plate lights, small lights, brake lights, etc. Wait; 1.5 Specifications are suitable for front headlights, speakers, etc.; Main power cables such as generator electrical hub cables and iron wires require 2.5 to 4 square millimeter wires. This only refers to the general car, the key depends on the maximum current value of the load. For example, the iron wire and the positive and negative polar power cord of the battery are used alone. More than millimeters. These wires will not be incorporated into the main cables.
