In the application of the whole vehicle, because there are many vibration areas, such as the door hinge area, the engine compartment vibration area, etc., in 2013, a small SUV wiring harness of a certain brand was broken. The plastic skin of the wires at the door hinge of the left front door wiring harness is aged and cracked, and one is broken (the fault is eliminated after the wiring harness is completely connected). The vibration area will undoubtedly affect the performance of the wire harness, especially if it is in a high temperature environment, it may even break; in an extremely low temperature environment, the wire harness will also break due to ice crystal freezing.
For the reliability of 0.13mm2 alloy wire in high temperature environment and vibration area, it is recommended to do vibration experiments and sports car experiments in the prototype stage to verify whether the wire is safe.
