Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically to a fixing device for automobile wiring harness routing. Background Technology

[0002] Automotive wiring harness fixing is a process that uses components or materials such as clips, cable ties, brackets, and adhesives to orderly fix the vehicle's electrical wiring harness to the body sheet metal, chassis, dashboard, and other locations. Its purpose is to prevent the wiring harness from shifting or being worn due to vehicle vibration and bumps, ensuring the safe and stable operation of the electrical system. At the same time, it optimizes the interior space layout and facilitates maintenance. The fixing method must be selected based on the wiring harness routing, environment, and structural characteristics of the installation location, and must balance reliability and assembly convenience.

[0003] The existing wiring harness routing method usually involves fixing the wires at pre-set points in the frame using cable ties. However, in actual production, this fixing method often fails to allow for the wire length after it is determined. As a result, if there are slight bends in some parts of the wiring harness during routing, the ends may not be able to be connected, which is quite inconvenient. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a fixing device for automotive wiring harness routing. It has the advantages of conveniently and effectively fixing the wiring harness while skipping fine-tuning of the fixing position to ensure normal connection at the rear end. It solves the problem that existing wiring harness routing methods usually use pre-set points in the vehicle frame for fixing with cable ties. However, in actual production, this fixing method usually does not allow for a margin after the wire length is determined. As a result, if there is a slight bend in some parts of the internal wiring harness during the routing process, the end may not be able to be connected, which is quite inconvenient.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A fixing device for automotive wiring harness routing includes a slide rail, a sliding sleeve that can slide along the outside of the slide rail, a gathering strip that is provided outside the sliding sleeve, a gathering hole that can accommodate the gathering strip that is provided inside the sliding sleeve, a slidable limiting member that extends into the gathering hole that is provided inside the sliding sleeve, an elastic member that is provided between the limiting member and the sliding sleeve, the limiting member being provided on the side near the slide rail and having an anti-slip pad that can contact the slide rail under compression, and a gathering tooth groove that can be linked with the limiting member to restrict the gathering strip that is provided outside the gathering strip.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the limiting member includes a limiting block connected to the sliding sleeve and whose width is adapted to the gathering strip. The top of the limiting block is provided with a linkage groove whose width is adapted to the width of the gathering tooth groove. The inner bottom wall of the linkage groove is fixedly provided with a locking tooth extending thereto and capable of engaging with the gathering tooth groove.

[0010] Furthermore, the width of the retaining tooth is smaller than the width of the gathering tooth groove, and gathering tooth grooves are provided on both sides of the gathering strip.

[0011] Furthermore, the elastic element is an elastic sheet and is distributed front to back on both sides of the limiting element, and the anti-slip pad is an elastic rubber anti-slip pad.

[0012] Furthermore, the end of the gathering strip is provided with an inclined chamfer, and the interior of the gathering strip is provided with a breakage-resistant keel.

[0013] Furthermore, the sliding sleeve and the gathering strip are fixed by fasteners. Each sliding sleeve has two fixing points on its exterior for fixing the gathering strip, and gathering holes are provided at the positions of the two fixing points respectively.

[0014] This utility model provides a fixing device for automotive wiring harnesses. By setting a slide rail, during fixing, a sliding sleeve can be slid along the slide rail, and the wiring harness can be placed beside it to simulate a fixing state. At the same time, the sliding sleeve is slid to determine the optimal fixing position, thereby ensuring that there will be no connection abnormalities at the end connection point. After the position is determined, the positions of the wiring harness and the sliding sleeve can be relatively fixed. Then, a gathering strip is wrapped around the wiring harness and inserted into the gathering hole, so that it compresses the limiting member. Thus, with the cooperation of the gathering tooth groove, the position of the gathering strip itself is limited. At the same time, the relative position between the sliding sleeve and the slide rail can be fixed by the anti-slip pad, thereby completing the overall fixing operation of the wiring harness. It has the advantages of convenient and effective fixing of the wiring harness while skipping fine-tuning of the fixing position to ensure normal connection at the rear end.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a fixing device for automotive wiring harness routing, including a slide rail 1, a sliding sleeve 2 that can slide along the outside of the slide rail 1, a gathering strip 3 that is provided on the outside of the sliding sleeve 2, a gathering hole 4 that can accommodate the passage of the gathering strip 3 that is provided inside the sliding sleeve 2, a slidable limiting member 5 that extends into the gathering hole 4 that is provided inside the sliding sleeve 2, an elastic member 6 that is provided between the limiting member 5 and the sliding sleeve 2, the limiting member 5 being provided on the side near the slide rail 1 and having an anti-slip pad 7 that can contact the slide rail 1 under compression, and a gathering tooth groove 8 that can be linked with the limiting member 5 to restrict the gathering strip 3 on the outside.

[0021] Furthermore, the limiting member 5 includes a limiting block 51 connected to the sliding sleeve 2 and whose width is adapted to the gathering strip 3. The top of the limiting block 51 is provided with a linkage groove whose width is adapted to the width of the gathering tooth groove 8. The inner bottom wall of the linkage groove is fixedly provided with a locking tooth 52 extending thereto and capable of engaging with the gathering tooth groove 8.

[0022] With this type of locking tooth 52, when the gathering strip 3 is inserted into the gathering hole 4, it can be restricted by the locking tooth 52, so that it can be used as a pawl to lock the gathering strip 3, thereby ensuring that the gathering strip 3 cannot be loosened after the wire harness is fixed, thus ensuring the fixing effect.

[0023] Furthermore, the width of the locking tooth 52 is smaller than the width of the gathering tooth groove 8, and gathering tooth grooves 8 are provided on both sides of the gathering strip 3.

[0024] The cable harness 3 with this design can be fixed by the cable harness grooves 8 on both sides, thus making the fixing position of the cable harness more flexible.

[0025] Furthermore, the elastic element 6 is an elastic sheet and is distributed front and back on both sides of the limiting element 5, and the anti-slip pad 7 is an elastic rubber anti-slip pad.

[0026] Furthermore, the ends of the gathering strip 3 are provided with inclined chamfers, and the interior of the gathering strip 3 is provided with anti-breakage keel.

[0027] In particular, the cross-sectional size of the gathering strip 3 should be adapted to the size of the gathering hole 4, so as to ensure that the gathering strip 3 will not cause the gathering tooth groove 8 to separate from the limiting member 5 due to the twisting gap after entering the gathering hole 4.

[0028] Furthermore, the sliding sleeve 2 and the gathering strip 3 are fixed by fasteners. The exterior of a single sliding sleeve 2 is provided with two fixing points for fixing the gathering strip 3, and a gathering hole 4 is provided for each of the two fixing points.

[0029] The securing strip 3 of this type of configuration can be freely fixed in any position. When a single sliding sleeve 2 cannot handle a large number of wire harnesses, a new sliding sleeve 2 can be added and connected to the slide rail 1. Then, the two securing strips 3 are connected to the two sliding sleeves 2 in a staggered manner. At this time, the wire harness can be placed between the two sliding sleeves 2, and the two securing strips 3 are inserted into the sliding sleeve 2 on the other side to complete the fixing of the wire harness between the two sliding sleeves 2.
