[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application herein are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0032] It should also be noted that in the embodiments of this application, the same reference numerals are used to represent the same components or the same parts.

It should be understood that the reference numerals are equally applicable to other identical parts or components.

[0033] Embodiments of this application provide a wire harness fixing device, as Figures 1-2 and Figures 4-5 shown. The wire harness fixing device includes a wire bundling structure 100, a plug-in connector 200, and a locking member 300. The wire bundling structure 100 is used to fix the cable. One end of the plug-in connector 200 is connected to the wire bundling structure 100, and the other end can pass through the mounting hole 11 on the mounting carrier 10 (such as the housing of the device) and be connected to the locking member 300, so that the mounting carrier 10 is clamped between the wire bundling structure 100 and the locking member 300.

[0034] When the wire harness fixing device is specifically used, the cable is fixed by the wire bundling structure 100, and then the end of the plug-in connector 200 away from the wire bundling structure 100 is passed through the mounting hole 11 on the mounting carrier 10 and locked by the locking member 300 on the other side of the mounting carrier 10, so that the mounting carrier 10 is clamped between the wire bundling structure 100 and the locking member 300, thereby realizing the installation and fixation of the entire wire harness fixing device on the mounting carrier 10. It is simple and convenient to use, and the wire bundling is stable and reliable.

[0035] In addition, it can be understood that the wire harness fixing device is mainly composed of three parts: a wire bundling structure 100 for fixing the cable, a plug-in connector 200 with one end connected to the wire bundling structure 100, and a locking member 300 adapted to the plug-in connector 200. The structure is simple and it is convenient to realize miniaturized design.

[0036] In one embodiment, as Figure 2 and Figure 5As shown in the figure, the connector 200 includes a plug rod 210 and a first engaging portion 220 disposed on the outer wall of the plug rod 210 along the length direction of the plug rod 210. The locking member 300 includes a ferrule 310 and a second engaging portion 320 disposed on the inner wall of the ferrule 310. The ferrule 310 can be sleeved on the plug rod 210 and connected to the plug rod 210 through the engagement of the first engaging portion 220 and the second engaging portion 320.

[0037] The connector 200 and the locking member 300 are arranged as above, so that the locking member 300 can be fixedly connected to any position in the length direction of the connector 200. Thus, the distance between the locking member 300 and the wire harness structure 100 can be flexibly adjusted during use, and the wire harness fixing device can be reliably fixed on the mounting carrier 10 for mounting carriers 10 of different thicknesses.

[0038] It can be understood that in order to adapt to different sizes of mounting holes 11 on the mounting carrier 10, the plug rod 210 can be designed in multiple specifications with different thicknesses. Correspondingly, the inner diameter of the ferrule 310 is also designed in multiple specifications with different sizes. As for the outer diameter of the ferrule 310, it only needs to be larger than the mounting hole 11.

[0039] In a specific embodiment, the connector 200 and the locking member 300 are detachably connected.

[0040] With this arrangement, it is convenient to disassemble the wire harness fixing device from the mounting carrier 10, which is convenient for the wire harness fixing device to be reused.

[0041] The wire harness fixing device in the embodiment of the present application can be used as an alternative to traditional cable ties, solving the problem that the one-time use of traditional cable ties is not environmentally friendly.

[0042] It can be imagined that the connector 200 and the locking member 300 can be detachably connected in various ways. In one implementation, as Figure 2 and Figure 3 shown, the first engaging portion 220 includes a plurality of first racks 221 disposed on the outer wall of the plug rod 210 along the axial direction. The plurality of first racks 221 are spaced apart in the circumferential direction of the plug rod 210; the first engaging portion 220 includes a plurality of second racks 321 disposed on the inner wall of the ferrule 310 along the axial direction. The plurality of second racks 321 are spaced apart in the circumferential direction of the ferrule 310. The ferrule 310 sleeved on the plug rod 210 can be rotated to switch the first rack 221 and the second rack 321 between the engaged state and the disengaged state.

[0043] When fixation is required, rotate the ferrule 310 to engage the first rack 221 on the outer wall of the plug rod 210 with the second rack 321 on the inner wall of the ferrule 310; when removal is required, rotate the ferrule 310 until the first rack 221 and the second rack 321 are staggered, and then the ferrule 310 can be removed.

[0044] Preferably, the insertion rod 210 and the plurality of first racks 221 are of an integral structure, and the ferrule 310 and the plurality of second racks 321 are of an integral structure. With this design, it is convenient for processing and manufacturing, and specifically, it can be integrally injection-molded by plastic.

[0045] In another implementation manner, not shown in the figure, the first engaging portion includes an external thread, and the second engaging portion includes an internal thread adapted to the external thread. The connection and disassembly between the ferrule and the insertion rod are realized by means of screw connection, with reliable connection and convenient disassembly. It can be understood that the plug-in member can directly adopt a threaded rod, and the locking member adopts a nut adapted to the threaded rod.

[0046] In some embodiments, as Figures 1-5 shown, the insertion rod 210 is made of a flexible material (including but not limited to nylon material and rubber). With this setting, the insertion rod 210 can be bent to avoid interference between the too-long insertion rod 210 and other components near the installation carrier 10.

[0047] In one embodiment, as Figures 1-2 shown, the wire bundling structure 100 includes a base 110 connected to one end of the plug-in member 200 and a wire bundling band 120 provided on the side of the base 110 facing away from the plug-in member 200. The wire bundling band 120 can adjust the tightness according to the number of cables, improving the stability of cable fixation. It can be understood that the wire bundling band 120 can also be replaced with a binding rope or the like.

[0048] In a specific embodiment, as Figure 1 shown, the wire bundling band 120 includes a band body 121 partially connected to the base 110 and a protrusion 122 provided at one end of the band body 121. A plurality of connection holes 1211 are provided at intervals along the length direction of the band body 121. The protrusion 122 can selectively engage with different connection holes 1211, thereby adjusting the size of the band body 121 wound into a ring shape to better adapt to cables of different diameters and quantities.

[0049] Furthermore, the wire bundling band 120 further includes a collar 123. The collar 123 is sleeved on the band body 121 and is near the protrusion 122. The collar 123 is used for the end of the band body 121 away from the protrusion 122 to pass through, improving the stability of the end of the band body 121.

[0050] In another embodiment, as Figures 4-5As shown, the wire harness structure 100 includes a base 110 connected to one end of the connector 200 and two elastic arms 130 spaced apart on the side of the base 110 facing away from the connector 200. The ends of the two elastic arms 130 away from the base 110 are bent towards each other to form an opening that tapers from the outside to the inside. The wire harness structure 100 is simple. When in use, the cable can be snapped into the accommodating area formed by the two elastic arms 130 and the base 110 through the opening, and the operation is convenient.

[0051] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0052] The above embodiments only represent several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
