The new energy vehicle wiring harness is mainly composed of "connectors, branches (including terminals), positioning clips, tape winding, etc.". Wiring harnesses play an important role in the composition of automobiles and require high quality. Here we introduce the manufacturing materials of wiring harnesses.

Connector
Tubes
Wires
The connector of the new energy vehicle wiring harness is each connection plug on the wiring harness. The connector is composed of locking tabs, seals, docking locking mechanism, brackets, covers, positioning clips, etc. In addition to the above structure, individual connectors and iron clips, and other auxiliary installation mechanism connectors can be divided into male connectors (plug-in male terminals) and female connectors (plug-in female terminals) according to the shape of the structure. According to the sealing performance can be divided into waterproof connectors (most plug sealing plug terminals, a small part of the plug ordinary terminals) and ordinary connectors: plug without sealing plug ordinary terminals.
Tubes of new energy vehicle wiring harness belong to the coverings on the wire harnesses, which include PVC pipes, PU pipes, corrugated pipes, fiber mesh pipes, foam pipes, rigid pipes, etc., and are divided into open-ended and closed-ended pipes according to the temperature resistance strength. The size of the pipe is indicated by the pipe diameter, the larger the diameter, the thicker the pipe. PVC pipe: the surface is generally smooth, hard in winter, easy to brittle break after a long time. There are open and closed mouth points. PU pipe: smooth surface, soft material, longer service life than PVC pipe. There are openings and closed mouths. The color is mostly black.
Wire of new energy vehicle wiring harness is composed of three parts: wire type, wire diameter, and color. Wire type: usually refers to the temperature resistance level of the wire. According to the automotive standard system in different regions, it can be divided into German standard, Japanese standard, the international standard, American standard, etc. The thickness of the insulation skin may vary between different wire types. Wire diameter: refers to the sum of the cross-sectional area of a single copper wire. Commonly available 0.35, 0.50, 0.75, 0.85, 1.0, 1.25, 2.0, 4.0, 6.0, 10.0, 15.0, 25.0, etc. Different wire diameters have different strands of copper wire and insulation outer diameter. The size of the wire diameter determines the thickness of the wire. Color: refers to the color of the wire insulation skin. The color of the wire is mainly divided into "primary and secondary colors" and "monochrome" two, usually with a number to indicate the color of the wire.
New energy vehicle wiring harness is an important part of the connection between various electrical and electronic equipment, playing a role in the transfer of electrical signals between electronic equipment and electrical appliances, is the carrier of electrical signal control of the car. It can be said that no wire harness does not exist in the car circuit. With modern society's higher and higher requirements for the car, the intelligence of the car is also improved, which puts forward higher requirements for the car wire harness. I believe our company's wire harnesses can meet the requirements of our customers.
