What are the basic materials of automobile wiring harness

The car wiring harness is the carrier of the connection of various parts of the car circuit. Someone once made a graphic metaphor, the car wiring harness is the blood vessel, the car engine is the heart, the heart is beating because of the blood vessel, the engine is running because of the wiring harness. It can be seen that the car wiring harness is important for the normal stability of the whole car circuit. Therefore, it is necessary to understand the products and technology of car wiring harness.

Wire harness refers to the touch terminals (connectors) made of copper material and wire and cable crimping, plastic pressure insulator or external metal shell, etc., with wire harness bound components of connection circuit. In short, it is connected to the electric wire of the car electrical appliances. The operating conditions and parameters of the car are reflected in the car computer through the wiring harness. On the other hand, the electronic technology content of car wiring harness has become an important objective to review car functions.

Classification of automobile wiring harnesses Car wiring harnesses can be divided into main wiring and small wiring harnesses. The main wiring harness includes engine wiring harness, center wiring box wiring harness, instrument panel wiring harness, cockpit wiring harness, etc. The small wire harness includes door wire harness, battery wire harness, ABS brake wire harness, etc. In addition, according to the difference of voltage, car wiring harness can be divided into high voltage wiring harness and low voltage wiring harness. The biggest characteristic of car high voltage line is high voltage and small current, high insulation function, so the insulation layer is often thicker and the core wire is thinner.

Production process of automobile wiring harness The production process of automobile wiring harness mainly includes opening, crimping, pre-assembly, final assembly, etc. The primary data of wiring harness is heat shrinkage data, which is an important insulation data in automobile wiring harness. Domestic heat shrinkable data for car manufacturing market accounted for a very low, only about 20 percent. It is worth mentioning that 80% of the world's shopping malls are occupied by America's Rykan and Japan's Sumitomo.

The development trend of automobile wiring harness follows the development of car electronization, economy, comfort, reliability and so on will be more and more prominent, and the requirements of wiring harness are abrupt and high. Domestic car wire harness shopping malls will gradually turn from low cost strategic shopping malls to more cost-effective shopping malls with higher technology content. Car wiring harness is also developing in the direction of high pressure, lightweight and standardization.
