When arranging and fixing high-voltage wire harnesses, avoid severe vibration areas. The high-voltage wire harness should be connected with the high-voltage equipment connected without relative vibration.
If the vibration area cannot be avoided, sufficient high-voltage wire margin should be left according to the vibration amplitude of the wiring harness layout and the maximum motion envelope of the moving parts, so as to avoid the wiring harness from being subjected to tension or tension.
When the vehicle is in a long-term turbulent state, it is easy to cause the position of the fixed point of the high-voltage wire harness to shift and fall off, which will cause the distance between the two fixed points to increase instantaneously, and the pulling of the wire harness will cause the internal nodes to pull off or be virtual. Therefore, the length of the high-voltage wire harness should be controlled reasonably. , the length should not only leave a margin to offset the stress caused by the drag of the movement, but also avoid distortion of the wire harness due to excessive length.
