I. What are the requirements for the rational arrangement of the wiring harness of new energy vehicles?

1. according to the actual installation position of the wire harness of new energy vehicle on the vehicle, in order to avoid the suspension and movement of the suspension and movement of the wire harness, taking into account the weight of the wire harness, the fixing method as well as the convenience of the fixing position, the wire harness must have a sufficiently reasonable fixing point and fixing method in order to fix it. 2. according to the direction of the wire harness of new energy vehicle, the specific shape of the body is set as the fixing point, and there is no pivot point between two fixing point distance in a straight line, usually no more than 300mm. in obtuse corners, the position can be arranged as a fixing point; in the right corner of the need to arrange two fixing points; sharp corner points on the harness to be avoided. 3. harness harness arrangement should be along the edges of the slots (aligned slots of the body design). Avoid direct pressure on the harness. Do not expose the wire harness in the cab. In locations where the location of the wire harness can be observed, set up eye-catching attraction points or eye-catching colors, here installed harness does not stand out and eye-catching. Arrange in the direction of projection according to the horizontal and vertical checkerboard grid, avoiding diagonal arrangements. The gap of the piping is even and the gap of the surrounding components is reasonable. 4. Do not directly contact with the sharp edges of the body, one to leave a gap and the other to increase the protection in order to avoid damage to the sharp edges of the human body's wiring harness external insulation, which may lead to a short-circuit accident. When installing on the vibration of moving parts, the length should be reserved according to the actual situation. This reserved length is based on the vibration amplitude of the part and the greater motion stroke of the moving part. Ensure that the reserved length is such that no vibration is transmitted to the harness and no tension is applied to the harness. If vibration or tension is applied to the new energy vehicle wiring for an extended period of time, this may result in a faulty connection between the terminals of the contacts/plugs within the wiring harness.
