Automotive wiring harnesses are the main body of automotive circuits. Automotive wiring harness usually refers to the circuit circuit formed by bushing, bundling, and connection after the contact terminal (connector) made of copper material and the wire and cable are crimped and contacted. Automotive wiring harnesses include wire and cable, connectors, accessories, packaging materials, processing equipment, wire harness manufacturing and downstream application industries in the manufacturing process.

For those who are new to the wiring harness industry, there is a lot of knowledge to understand and master. Take the wires and cables used in wire harness manufacturing, the types, models, standards, specifications, etc. can not be clearly explained for a while. In the automotive wiring harness, we use many kinds of wire diameter, generally when designing the wiring harness, are according to the current to select the specifications and models of the wire, such as light small current car wiring harness generally 0.5 square millimeter or 0.75 square millimeter wire, power windows, controllers, audio, power seats and other car wiring harnesses generally use 1 square millimeter wire, air conditioning, engine and other main control high-current automotive wiring harness, Usually 2 square millimeters, 2.5 square millimeters or even 4 square millimeters of wires are used.

The above is just a simple selection of commonly used automotive wiring harnesses, and we need to pay attention to the fact that different car companies also have different requirements for different automotive wiring harnesses. Specific different models and different electrical systems have different needs, and the design of automotive wiring harnesses will also have different safety performance requirements and standard requirements. In the specific application, should be selected and designed according to the actual needs, Huazhan cable has more than ten years of experience in the development and manufacturing of wiring harnesses, in order to ensure the quality, reliability and safety of automotive wiring harnesses.
