[0044] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0045] Combine the following Figure 1 , describing an embodiment of the utility model.

[0046] According to an embodiment of the utility model, on one hand, a wire harness drag chain fixing device is provided, which is suitable for fixing the wire harness drag chain on a vehicle body, and the wire harness drag chain fixing device includes a vehicle body connecting portion 1 and a drag chain connecting portion 2.

[0047] The vehicle body connecting portion 1 is suitable for being connected to a vehicle body.

[0048] The drag chain connection part 2 is connected to the vehicle body connection part 1, and the drag chain connection part 2 is provided with a fixing hole 3, and the fixing hole 3 is arranged as a long strip structure. The length direction of the fixing hole 3 is consistent with the length direction of the wiring harness drag chain. The drag chain connection part 2 is suitable for being connected to the wiring harness drag chain through a connector inserted in the fixing hole 3, and the position of the connector along the length direction of the fixing hole 3 is adjustable.

[0049] This embodiment is connected to the vehicle body through the vehicle body connection part 1 to achieve the position fixation of the wiring harness drag chain fixing device, and then connected to the wiring harness drag chain through the drag chain connection part 2, and finally achieves the fixed installation of the wiring harness drag chain. Specifically, by opening the fixing hole 3 on the drag chain connection part 2 and setting the fixing hole 3 as a long strip structure, the installation range between the drag chain connection part 2 and the wiring harness drag chain is increased. Since the movement direction of the wiring harness drag chain is the same as its length direction, when the drag chain connection part 2 is installed with the wiring harness drag chain, the length direction of the fixing hole 3 is the same as the length direction of the wiring harness drag chain, which can enhance the flexibility of the wiring harness drag chain when it is installed with the drag chain connection part 2, and avoid the position error caused by the degree of freedom of the wiring harness drag chain itself and the misalignment caused after maintenance affecting the installation.

[0050] Specifically, the harness drag chain fixing device and the harness drag chain can be connected by means of a connector plug-in, making the entire installation process simpler and less costly. In this embodiment, the fixing hole 3 can be set to a long strip structure. When installing the harness drag chain, the installation position of the harness drag chain can be aligned with any position in the length direction of the fixing hole 3 according to its own situation, and then connected by a connector, so that the installation position of the harness drag chain is adjustable, ensuring the convenience of installation and the accuracy of the position. When the harness drag chain is inspected and disassembled, it is only necessary to remove the connector to inspect or replace the harness drag chain, without disassembling other parts. When installing, first connect the vehicle body connection part 1 to the vehicle body, then connect the drag chain connection part 2 to the harness drag chain through the connector, and finally fix the wire harness on the harness drag chain, and cover the drag chain cover to achieve installation.

By ensuring that the length directions of the multiple fixing holes 3 are arranged in parallel, and the length direction of the fixing holes 3 is the same as the length direction of the harness drag chain, the error tolerance rate of the harness drag chain in the length direction can be increased, thereby improving the installation efficiency.

The angle between the vehicle body connection part 1 and the drag chain connection part 2 can adapt to the connection between the harness drag chain connection position and the vehicle body connection position to achieve angle twisting.

[0055] In some embodiments, the vehicle body connection portion 1 and the drag chain connection portion 2 are constructed as an integrated structure.

[0056] In this embodiment, the body connection part 1 and the drag chain connection part 2 of the integrated structure can enhance the connection strength between the body connection part 1 and the drag chain connection part 2, and further enhance the connection strength between the harness drag chain and the body. The body connection part 1 and the drag chain connection part 2 are an integrally formed part, and the harness drag chain does not need to be disassembled when the harness drag chain is inspected and repaired, which not only facilitates the installation process and reduces the cost, but also ensures the accuracy of the installation position.

[0057] In some embodiments, the wire harness drag chain fixing device is configured as an L-shaped sheet metal part.

[0058] In this embodiment, when the vehicle body connection surface and the wiring harness drag chain installation surface are perpendicular to each other, the L-shaped wiring harness drag chain device can achieve the connection between the two.

[0059] In some embodiments, the connecting member includes a bolt and a nut, and the bolt passes through the fixing hole 3 and the wiring harness drag chain is connected to the nut by threads.

[0060] In this embodiment, the end of the bolt abuts against the drag chain connection part 2, the nut abuts against the connection end of the harness drag chain, and the bolt and the nut clamp together to fix the harness drag chain and the drag chain connection part 2. The provided bolt and the nut are connected by threads, which can improve the disassembly and assembly efficiency between the drag chain connection part 2 and the harness drag chain. When the provided bolt is not positioned by the nut, it can slide at any position in the fixing hole 3, which can improve the fault tolerance rate when the drag chain connection part 2 and the harness drag chain are installed.
