How to check if the car harness is qualified?

In addition to the normal operation of the various electrical appliances, the qualified automotive wiring harness should also check the following points:

1. The connection between the plug and the electrical appliance should be tight, the terminal is flexible, and it is not loose. The looseness of the plug of the automobile harness directly affects the use of the automobile electrical appliance, and it is easy to connect or disconnect the circuit, which makes the electrical appliance unusable. This situation is most common, for example: The wiring harness plug of the car may affect the following points: The generator can generate electricity. Because the car harness connector is disconnected, the battery cannot be powered, and the turn signal is not bright. Therefore, it is necessary to check that the car harness connector should be fastened.

2. Whether the shrink sleeve of the terminal is tightly wrapped, the shrink sleeve of the unqualified automobile harness terminal is loose, and the loosened wire body is prone to short circuit and the car is on fire.

3. The low-voltage inner wire is made of flame-retardant wire, and the low-voltage wire can withstand the high temperature of 200 degrees Celsius.

4. The automobile wiring harness sheath should be wrapped in place, the automobile wiring harness sheath starts to be insulated, and the function of oil separation is used. Why is the automobile wiring harness capable of starting corrosion resistance, high temperature resistance, aging resistance, etc., all because of the automobile harness sheath The protection is achieved.

5. The wire of a good car harness is made of red copper, so according to the weight of copper than aluminum, the same amount of wire harness is the best. The wire harness made of copper clad aluminum is lighter. of.
