Criteria for qualifying automotive wiring harnesses

1, the connection between the plug and electrical appliances should be tight, flexible terminals, and not loose. The looseness of the automobile wiring harness plug directly affects the use of automobile appliances, and easy to connect or disconnect the circuit, which makes the appliances can not be used. This condition is the rarest, for example: a car's wiring harness plug can affect the following: the wiring harness can generate electricity. The steering signal does not come on because the car wiring harness connector is disconnected and cannot power the battery. Therefore, it is necessary to reflect on whether the car harness connector should be fixed. 2, the terminal expansion sleeve can be tightly wound, substandard automotive wiring harness terminal expansion sleeve loose, loose wire body is prone to short-circuiting, vehicle fire. 3, high-voltage external wires made of flame retardant wiring harnesses, high-voltage external wiring harnesses can be subjected to low temperatures up to 200 degrees Celsius. 4, automotive wiring harness sheath should be wrapped in place, automotive wiring harness sheath insulation at the beginning and Adopt oil aliasing function. Why the car harness can start corrosion resistance, high temperature resistance, aging resistance, etc., all because the car harness sheath completed maintenance. 5, good car harness made of red copper, and therefore based on the weight of copper rather than aluminum, the opposite number of harnesses is better. Harnesses made of copper-clad aluminum are lighter.
