Description

Technical Field

[0001] This utility model relates to the technical field of accessories for wiring harness installation, and in particular to a fastener for fixing automotive wiring harnesses. Background Technology

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network. A wiring harness is an assembly consisting of copper-plated contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and bundled together to form a connected circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. Wire harnesses have a wide range of applications, including automobiles, home appliances, computer and communication equipment, and various electronic instruments.

[0003] During installation, automotive wiring harnesses generally need to be tightened to prevent them from becoming tangled. Chinese Patent No. CN209738988U discloses a fastener for a new energy vehicle wiring harness, including a first connecting plate and a second connecting plate that cooperate with each other. A connecting device is provided at one end of the first connecting plate and the second connecting plate opposite to each other. The connecting device includes two connecting rods symmetrically mounted on the first connecting plate. A connecting groove that cooperates with the connecting rods is opened on the second connecting plate. Limiting blocks can be movably installed on both connecting rods. Limiting grooves that cooperate with the limiting blocks are opened on the inner sidewalls of both connecting grooves. Clamping plates can be movably installed on the inner sidewalls of the opposite sides of the first connecting plate and the second connecting plate.

[0004] The existing automotive wiring harness fastening structure uses two arc-shaped clamps to clamp the wiring harness when it is being limited and fastened. However, this method is prone to the following problems when clamping the automotive wiring harness: when the automotive wiring harness is pulled, it can only rely on the surface friction between the wiring harnesses to offset the pulling force. This method results in poor tensile strength of the automotive wiring harness and has defects. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a fastener for fixing automotive wiring harnesses.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fastener for fixing automotive wiring harnesses includes a base plate, a cover plate rotatably connected to one side of the top of the base plate, the base plate and the cover plate being connected by a quick-release fastener, a plurality of equidistant lower slots being provided on the top of the base plate, the base plate being a hollow structure, an installation opening being provided on the lower slots, an extrusion member being installed in the installation opening, the extrusion member including an elliptical extrusion block located in the installation opening, an insertion hole being provided at an eccentric position on the elliptical extrusion block, and an adjustment rod being provided in the insertion hole.

[0008] As a further embodiment of this utility model, the outer wall of the mounting port is provided with a mounting hole, and a first threaded sleeve is fixed in the mounting hole. A second threaded sleeve is fixed in the inner wall of the mounting port away from the mounting hole. The adjusting rod passes through the first threaded sleeve and the insertion hole. The portion of the adjusting rod corresponding to the first threaded sleeve and the second threaded sleeve is provided with threads.

[0009] As a further embodiment of this utility model, a guide strip is fixed to the outer wall of the adjusting rod, and a guide groove adapted to the guide strip is provided in the insertion hole.

[0010] As a further embodiment of this utility model, an upper groove is provided on the cover plate at the position corresponding to the lower groove.

[0011] As a further embodiment of this invention, a fixing cap is fixed to the outer end of the adjusting rod.

[0012] As a further embodiment of this utility model, the quick fastener includes a buckle fixed to the side of the base plate, and a locking head is fixed on the cover plate at the position corresponding to the buckle. The buckle and the locking head are adapted to each other, and the base plate and the cover plate are locked together by the buckle and the locking head. The quick fastener is existing technology.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes a base plate, cover plate, buckle, clip, lower groove, and extrusion block located within the mounting opening. This extrusion block rotates, allowing the adjusting rod to advance. As the adjusting rod rotates, the elliptical extrusion block deflects counter-clockwise. Based on the shape of the elliptical extrusion block, and because the adjusting rod passes through it at an eccentric position, with the guide strip located within the guide groove, the elliptical extrusion block deflects with the adjusting rod and slides along the guide strip on the adjusting rod. This further extrudes the wire harness, effectively solving the problems raised in the prior art. It allows for wire arrangement and independent extrusion and fixing of each wire. The longer elliptical extrusion block provides a larger extrusion area, avoiding excessive extrusion pressure that could damage the wire harness due to localized small-area extrusion, thus achieving stability and preventing pulling.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Reference Figure 1-4 A fastener for fixing automotive wiring harnesses includes a base plate 1, a cover plate 2 rotatably connected to one side of the top of the base plate 1, the base plate 1 and the cover plate 2 being connected by a quick-release fastener, a plurality of lower slots 5 being equidistantly opened on the top of the base plate 1, the base plate 1 being a hollow structure, an installation port 7 being opened on the lower slots 5, an extrusion member 8 being installed in the installation port 7, the extrusion member 8 including an elliptical extrusion block 11 located in the installation port 7, an insertion hole 15 being opened at an eccentric position on the elliptical extrusion block 11, and an adjustment rod 12 being provided in the insertion hole 15.

[0023] In this embodiment, the outer wall of the mounting port 7 is provided with a mounting hole 9, and a first threaded sleeve 10 is fixed inside the mounting hole 9. A second threaded sleeve 18 is fixed on the inner wall of the mounting port 7 away from the mounting hole 9. The adjusting rod 12 passes through the first threaded sleeve 10 and the insertion hole 15. The portion of the adjusting rod 12 corresponding to the first threaded sleeve 10 and the second threaded sleeve 18 is provided with threads 14.

[0024] In this embodiment, a guide bar 16 is fixed to the outer wall of the adjusting rod 12, and a guide groove 17 adapted to the guide bar 16 is provided in the insertion hole 15.

[0025] In this embodiment, an upper groove 6 is provided on the cover plate 2 at the position corresponding to the lower groove 5.

[0026] In this embodiment, a fixing cap 13 is fixed to the outer end of the adjusting rod 12.

[0027] In this embodiment, the quick fastener includes a buckle 3 fixed to the side of the base plate 1, and a locking head 4 fixed on the cover plate 2 at the position corresponding to the buckle 3. The buckle 3 and the locking head 4 are adapted to each other. The base plate 1 and the cover plate 2 are locked by the buckle 3 and the locking head 4. The quick fastener is the prior art.

[0028] Working principle: This wire harness fastener uses a base plate 1, cover plate 2, buckle 3, clamp 4, lower slot 5, and an extrusion piece 8 located within the mounting opening 7. To use this fastener, open cover plate 2, place each wire in the wire harness into the lower slot 5, close cover plate 2, and lock base plate 1 and cover plate 2 using buckle 3 and clamp 4. To increase wire stability, the fixing cap 13 can be rotated counterclockwise to rotate the adjusting rod 12. Since the first threaded sleeve 10 and the second threaded sleeve 18 are both compatible with the corresponding threads 14, they can rotate, allowing the adjusting rod 12 to advance. It should be noted that when the elliptical extrusion block 11 is not exerting an extrusion effect, the end face of the adjusting rod 12 is flush with the inner wall of the second threaded sleeve 18. There is space for the adjusting rod 12 to move, meaning that the adjusting rod 12 does not reach the inner bottom end of the second threaded sleeve 18. When the adjusting rod 12 rotates and advances, the elliptical extrusion block 11 can deflect counterclockwise. Based on the shape of the elliptical extrusion block 11, and because the adjusting rod 12 passes through and is located at the eccentric position of the elliptical extrusion block 11, and the guide strip 16 is located in the guide groove 17, the elliptical extrusion block 11 deflects with the adjusting rod 12, and the elliptical extrusion block 11 can slide on the guide strip 16 on the adjusting rod 12. The elliptical extrusion block 11 further extrudes the wire harness, effectively solving the problems raised in the background technology, realizing the arrangement of wires, and independently extruding and fixing each wire to achieve stability and prevent pulling.
