The high-voltage wire harness should avoid routing from sharp objects, metal frame edges, welding seams, and fixing holes on the car body, so as to avoid damage to the high-voltage wire harness due to assembly operations, vibration and friction, which may cause damage to the wire harness and cause safety accidents.
If sharp edges cannot be avoided or holes are required, corresponding protective devices (such as rubber parts, rubber rings, etc.) should be added to the sharp edges such as via holes, or protective structures should be added to the surface of the wires to prevent the high-voltage wire harness from being damaged during installation.
Considering the strength of the high-pressure rubber parts, the combination of rubber and plastic is used to ensure the fixed matching of the sheet metal and the tensile strength.
The high-voltage wire harness is generally thick, and the bending stress is relatively large. The high-voltage connector is large in size, and the volume of the rubber part design will be much larger. At the same time, the fixing strength requirements will be high. The structure is relatively complicated, and the material selection requirements will be more demanding. high.
