The buckle-proof design of the automotive wiring harness can effectively prevent the wrong direction or position of the wiring harness. The OEM usually designs different sizes, different shapes, different directions, and different fixed installation methods on the automotive sheet metal. Sheet metal holes or slots, etc., There are also obvious differences in the specifications of the clips, buckles, and cable ties on the wiring harness, which can effectively avoid errors in wiring harness loading and installation.
Part of the ceiling wiring harness branches are fixed by adhesive tape, and the blue tape should be used to mark the pasting position on the wiring harness. The OEM loads the wiring harness and the ceiling object according to the marked position to prevent pasting and fixing errors.
There should be no heavy-colored wires in the same sheath. If heavy-colored wires cannot be avoided, different wire diameters should be used. The ground terminal of the common pressure connection at the other end can use wires of the same color and diameter.
If the total length of a wire harness is greater than 1.30m, it is forbidden to add optical fibers in the wire harness. The selection of optical fibers and the relevant technical requirements for protection should take into account various constraints (temperature, erosiveness, bending radius) in the use area, regardless of whether they are connected to the instrument or not. The optical fiber should comply with the technical requirements of STE 9629787199, the average bending radius of the optical fiber should not be less than 25mm, and some pulse generators should be added if necessary.
