1. The terminal of the terminal wire is dropped. This situation is just the opposite of the situation of the third party above. The terminal machine is adjusted too loosely when the machine is adjusted, so that the terminal cannot tightly wrap the wire harness.
2. The wiring harness connector is not pierced in place. This situation is mainly manifested in the wiring harness assembly process. The electric vehicle wiring harness is not in place when it is inserted into the connector housing. Under normal conditions, there will be a "click" when it is inserted in place. To ensure that it is in place , You also need to do a pullback action, that is, hold the connector in one hand and pull the wire tightly in the other hand, be careful not to use too much force to avoid breaking the wire harness.
3. The electronic wire harness is soldered. When the wire harness is welded, the wire core cannot be tinned, or when the contact surface of the two wire cores is too small, there will be a virtual welding phenomenon. Since the welding place needs to be covered with an insulating sleeve, the appearance is not visible. If it does not come out, some problems can be found during the quality inspection process. If this kind of wiring harness is installed on the equipment, it will simply fail.
4. There are three reasons for the broken wire core of the electronic wiring harness: First, the quality of the wire harness raw material cable is not good enough, the flexibility is not good, or the wire diameter is lacking; The third is that when the wire harness is crimped to the terminal, the machine is adjusted too tightly, and the lower pressure of the blade is too large, resulting in the cracking of the core wire.
