Abstract
Description
Technical Field
[0001] The utility model relates to a vehicle wire harness fixing device, belonging to the technical field of wire harness fixing. Background Art
[0002] The application scenarios of dump trucks are complex, the working conditions are harsh, there is a lot of mud and water, the vehicle is severely bumpy during operation, and the wiring harness is prone to wear, so it is necessary to protect it, avoid interference with other parts, and fix it firmly.
[0003] At present, the commonly used wiring harness fixing methods for dump trucks are generally the following two:
[0004] Method 1: Punch holes on the fixed surface and use cable ties with bases to fix them through the holes. First, for this method, different types of cable ties are needed to fix one or multiple wire harnesses, and cable ties are not universal. Secondly, for locations such as welding the frame, punching holes changes the structural stress. In addition, the frame is a square tube as a whole, and the base of the cable tie cannot be used through it, so it is not applicable. Finally, there are often gaps in the base mounting holes. During the bumpy process of the vehicle, the shaking of the wire harness will cause the base to be worn by the edges of the mounting hole, reducing its service life.
[0005] Method 2: Use a welded threaded seat, and assemble a rubber sleeve clamp, a rubber-impregnated clamp, or a fixed seat tie on the threaded seat. This assembly process requires tightening the bolts, which has a high assembly cost. In addition, the clamp size is fixed in a standard, and it is often not tightly fixed, and there is a gap between the wire harness. Different diameter clamps are required to fix wire harnesses of different diameters, and the classification of clamps increases the assembly cost. Moreover, the threaded seat consumes relatively more steel. Summary of the invention
