Is there a difference between a regular harness and an automotive harness?

Are there any differences between general wiring harnesses and automotive wiring harnesses? Automotive wiring harness standards also have very severe requirements for data: including their electrical functions, data dispersion, temperature resistance, etc., which are higher than those of ordinary wiring harnesses, especially those involving safety: such as direction control systems and brakes. The wiring harnesses of important components have more severe requirements. Standard technology of automobile wiring harness: The variety of electronic products on automobiles is constantly adding, which has become a problem faced by automobile manufacturing industry. With the continuous improvement of people's requirements for comfort, economy and safety, how to arrange many wiring harnesses more usefully and reasonably in the limited automobile space, so that automobile wiring harnesses can play a greater role.

Commonly used standards for automotive wiring harness standards 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 and other square millimeters), each of which has an allowable load current value and is equipped with wires of electrical equipment with different power. Taking the vehicle wiring harness as an example, the 0.5 standard wire is suitable for exterior lights, indicator lights, door lights, ceiling lights, etc.; The 0.75 standard line is suitable for license plate lights, front and rear small lights, brake lights, etc.; 1.0 standard line is suitable for turn signals, fog lights, etc.; 1.5 Standard line is suitable for headlights, horns, etc.; Main power lines such as generator armature lines, ground lines, etc. require 2.5 to 4 square millimeters of wires. This only refers to general cars. The key depends on the maximum current value of the load. For example, the ground wire and positive power wire of the battery are special automobile wires used alone, and their wire diameters are relatively large, at least more than ten square millimeters. These "Big Mac" wires will not be woven into the main harness. Premier Operations: Wiring Harness, Automotive Wiring Harness, Wiring Harness Processing, Wire Rod Processing, Terminals, Cold Pressed Terminals, Wiring Harness Processing Plant, etc. Automotive wiring harness standard, which is different from ordinary household wires. Generally, household wiring harnesses are copper single-core wires with a certain hardness. Automobile wiring harnesses are all copper multi-cored flexible wires, some of which are as thin as hair, and several or even dozens of soft copper wires are wrapped in plastic insulated pipes (polyvinyl chloride), which are soft and not easy to break. Due to the particularity of automobile work, the manufacturing process of automobile wiring harnesses is more special than other general wiring harnesses.
