Description

Technical Field

[0001] This utility model relates to the field of wire harness fixing technology, and in particular to a bracket for fixing wire harnesses. Background Technology

[0002] With the intelligent development of new energy vehicles, wiring harnesses used in these vehicles are becoming increasingly common, which also places higher demands on their installation. High-voltage wiring harnesses, in particular, are thick and rigid, making assembly relatively difficult. Furthermore, the limited number of fixing points during assembly makes them prone to twisting. In actual production, cable ties or plastic or metal clips are typically used to directly fix the wiring harness to the vehicle body. Alternatively, to prevent wear or twisting caused by vibrations during vehicle operation, rubber rings and brackets are used together. The rubber rings protect and limit the wiring harness, but in practice, workers often need to first assemble the bracket and rubber ring, then use cable ties to secure the wiring harness, and finally use screws to fix the bracket to the vehicle body. The bracket fabrication and wiring harness fixing process is relatively complex, increasing the workload for workers.

[0003] For example, Chinese utility model patent CN 217508169 U, with an authorization announcement date of September 27, 2022, discloses a metal rubber fixing bracket for high-voltage wiring harnesses in electric vehicles. The bracket includes a wiring harness sleeve with a C-shaped groove inside. The opening of the C-shaped groove is inverted V-shape. A fixing frame is placed over the opening of the wiring harness sleeve. The fixing frame and the wiring harness sleeve are fixed together by cable ties. A fixing plate protrudes horizontally from one end of the fixing frame, and mounting holes are provided on the fixing plate. Anti-rotation blocks are provided on the side of the fixing plate. The high-voltage wiring harness is secured by using the wiring harness sleeve to enclose it, then the fixing frame is placed over the opening of the wiring harness sleeve, and finally the wiring harness sleeve and fixing frame are secured with cable ties. The fixing frame is then installed onto the vehicle body through the mounting holes, thus fixing the high-voltage wiring harness. However, the wiring harness fixing process described above is complex. When the wiring harness needs to be moved to a different location, the fixing frame and cable ties must be loosened, involving numerous steps. The wiring harness is not easy to remove, increasing the workload for workers. Utility Model Content

Specifically, the second fixing part 12 is connected with the vehicle body through the fastener passing through the mounting hole 121, in order to avoid that the fixing support 1 rotates relative to the vehicle body after being connected, the second fixing part 12 further abuts against the vehicle body through the anti-misalignment block 122, and the anti-misalignment block 122 can abut against a panel of the vehicle body or be inserted into a metal hole of the vehicle body, as long as the anti-rotation effect can be achieved. Preferably, the mounting hole 121 is a threaded hole or a through hole, when the mounting hole 121 is a threaded hole, the fastener can be a self-locking screw or a bolt, when the mounting hole 121 is a through hole, the fastener is a bolt, and a nut matched with the bolt is used on the other side of the vehicle body. The anti-misalignment block 122 extends in a direction perpendicular to the plane where the mounting hole 121 is located, so that the anti-misalignment block 122 and the mounting hole 121 can be positioned and installed at the same time, and then the second fixing part 12 is installed.
