Automotive wiring harness assembly and manufacturing process
manufacturing process includes
1.Plug the wire into the plug
2.Proceed with the wiring process for the plugged products
3.Wrap the laid thread with the outer material, which is equivalent to the outer shell
4.Put zakadin on the line
5.Test the electrical performance of the product using a conduction bench
6.After the electrical performance test, the appearance and dimensions of the product are inspected
7.Finally, inspect the firewall to ensure that the quality reliability of the wiring harnesses delivered to the vehicle is 100%


Materials for car wiring harnesses
Automotive wiring harnesses are mainly composed of plugs, wires, and casing protective materials.
Aluminum wires are used: Aluminum has excellent electrical and thermal conductivity. The core driving force is lightweight and cost reduction. The density of aluminum is 30% of that of copper, effectively reducing the weight of the wire harness. The price of raw materials is lower than that of copper. The key is that its performance is more stable and its electrical conductivity is also relatively excellent
Insulating sheath material: Made of PVC material, it has strong heat resistance and good corrosion resistance. The working temperature range can reach above 105℃. It can be used in all areas except the engine.
The terminals are made of copper alloy, brass, phosphor bronze, etc., which have excellent wear resistance, electrical conductivity and corrosion resistance, solving the problem of smooth operation of the automotive system
Sealing material: Mainly silicone rubber is used. It can ensure the strength of the seal under extreme conditions and has excellent pressure and temperature resistance.
Why do cars need wiring harnesses?
Wiring harnesses mainly transmit energy and signals to automobiles. They are divided into low-voltage wiring harnesses and high-voltage wiring harnesses. High-voltage wiring harnesses are generally used in engines, where the high-voltage current they transmit is very large. Low-voltage wiring harnesses are typically used in parts such as car doors and headlights where small currents are transmitted. The wiring harness of a car is mainly used to control the power of the entire vehicle, output signals, and ensure the normal operation of the vehicle.
