Automotive wiring harness structure

QIDI CN TECHNOLOGY CO.,LTD specializes in the design, research and development, production and sales of the core links of the automotive wiring harness industry chain. It is an innovative technology enterprise that mainly produces automotive wiring harnesses; high-precision mold development, design, manufacturing, sales and technical services; vehicle wiring harness assemblies and other core products.

At present, whether it is a high-end luxury car or an economical ordinary car, the structure of the car wiring harness is basically the same, which is assembled by wires, plug-ins and sheaths.
Automobile wires are also called low-voltage wires. They are different from ordinary household wires. Common household wires are copper single-core wires with a certain degree of hardness. However, automobile wires are copper multi-core wires.
Due to the particularity of the automotive industry, the manufacturing process of automotive wiring harnesses is also more special than other ordinary wiring harnesses.
Automotive wiring harnesses are roughly divided into two categories:
1. Divided by European and American countries, including China: use TS16949 system.
2. Mainly Japan: Toyota and Honda are their own systems.
With the increase of automobile functions and the widespread application of electronic control technology, there are more and more electrical devices and more and more wires, and automobile wiring harnesses become thicker and heavier. Therefore, advanced cars have introduced CAN bus configuration and adopted a multiplex transmission system. Compared with the traditional wiring harness, the multiplex transmission device greatly reduces the number of wires and plug-ins, making the wiring simpler.
usual format
Common specifications for wires in automobile wiring harnesses include 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. square millimeters (the nominal cross-sectional area of ​​Japanese cars is 0.5, 0.85, 1.25, 2.0, 2.5, 4.0, 6.0 and other square millimeter wires), 0.5 specification car wires are suitable for instrument lights, indicator lights, door lights, dome lights; 0.75 specification car wires are suitable for license plate lights, front and rear lights, brake lights; 1.0 specification car wires are suitable Used for turn signals and fog lights; 1.5 specification car wires are suitable for headlights and horns; main power wires, such as generator armature wires and grounding wires, require 2.5~4 square millimeters
