Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive wiring harness fixing technology, and in particular to an automotive wiring harness for preventing loosening. Background Technology
[0002] Automotive wiring harnesses are the main network of automotive circuits; without wiring harnesses, there would be no automotive circuits. A wiring harness is an assembly that connects circuits by crimping copper contact terminals (connectors) to wires and cables, then molding an insulator or adding a metal shell, and finally bundling the wires together.
[0003] For example, patent (CN 221102913 U) discloses an automotive wiring harness to prevent loosening, including a male terminal housing, a female terminal housing, and multiple wires fixedly connected between the male and female terminal housings. A binding wire is fixedly connected to the side of the male terminal housing near the wires, and the end of the binding wire away from the male terminal housing is detachably connected to the side wall of the female terminal housing. Compared with the existing technology of using automotive wiring harness troughs, corrugated tubes, or sheaths to gather the wires for easy wiring, this product uses a wound binding wire to achieve the same gathering function. Its structure is simple, easy to operate, and is a low-cost alternative. Depending on the number of windings, it can be applied to automotive wiring harnesses with different numbers of wires. The more wires, the fewer the windings; the fewer the wires, the more the windings.
[0004] When using the above technology, the following technical problems were found in the existing technology: the existing technology is not convenient for tightening and gathering automotive wiring harnesses of different numbers and thicknesses. Therefore, it is necessary to adjust and tighten the harnesses according to the different numbers and thicknesses of automotive wiring harnesses under a fixed-distance binding line. Then, the binding line limits the automotive wiring harnesses and performs secondary clamping and positioning to effectively prevent the stress of the automotive wiring harnesses of different numbers and thicknesses from causing loosening. Therefore, it is necessary to fix and protect the automotive wiring harnesses by binding lines. To this end, we have designed an automotive wiring harness to prevent loosening, providing another technical solution to the above technical problems. Summary of the Invention
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A type of automotive wiring harness for preventing loosening includes two fixing plates. One fixing plate has a fixed shaft internally connected to it, and the other fixing plate has a rotating shaft internally connected to it. The top ends of the fixed shaft and the rotating shaft, which are close to each other, are fixed with L-shaped claws. A binding wire is assembled between the two L-shaped claws. A plurality of meshing teeth are fixed to one end of the outer side of the rotating shaft, and a pawl is rotatably connected to one end of the rotating shaft. One end of the pawl engages with the meshing teeth.
[0007] As a preferred embodiment of the automotive wiring harness provided by this utility model for preventing loosening, a plurality of automotive wiring harnesses are rotatably connected to the inner sides of the fixed shaft and the rotating shaft.
[0008] In a preferred embodiment of the automotive wiring harness provided by this utility model for preventing loosening, both ends of the binding wire are fixed with connecting ends, and the interior of the connecting ends is slidably connected to L-shaped claws.
[0009] As a preferred embodiment of the automotive wiring harness provided by this utility model for preventing loosening, guide grooves are provided at both ends of the inner outer side of the rotating shaft, and guide rings are fixed at both ends of the other fixing piece, with the inner side of the guide rings rotatably connected to the guide grooves.
[0010] In a preferred embodiment of the automotive wiring harness provided by this utility model for preventing loosening, a spring is fixed to the bottom end of the pawl, a limit block is fixed to the bottom end of the spring, and one end of the limit block is fixed to another fixing piece.
[0011] As a preferred embodiment of the automotive wiring harness for preventing loosening provided by this utility model, one end of the rotating shaft is fixed with several hand-operated claws.
[0012] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.
[0013] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:
[0014] This utility model provides a method to prevent loosening of automotive wiring harnesses. By rotating a hand pawl, a rotating shaft and guide ring are connected to rotate. This causes the shaft to rotate one of the L-shaped pawls and one end of the binding wire, tightening the binding wire for different numbers and thicknesses of automotive wiring harnesses. During this process, the pawl slides against the meshing teeth. When tightened to the appropriate position, the pawl effectively engages and positions the meshing teeth, improving the stability of the binding wire for different numbers and thicknesses of automotive wiring harnesses. Since the stress on the binding wire can cause the rotating shaft to reverse, the pawl effectively prevents the rotating shaft and meshing teeth from reversing, avoiding loosening of the binding wire for different numbers and thicknesses of automotive wiring harnesses.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0025] Please refer to Figures 1-4 A method for preventing loosening of automotive wiring harnesses includes two fixing plates 1. One fixing plate 1 has a fixed shaft 2 fixedly connected inside, and several automotive wiring harnesses are rotatably connected to the inner side of the fixed shaft 2 and the rotating shaft 13. The other fixing plate 1 has a rotating shaft 13 rotatably connected inside, and several hand-operated claws 4 are fixed to one end of the rotating shaft 13. An L-shaped pawl 11 is fixed to the top of the fixed shaft 2 and the rotating shaft 13 near each other. A binding wire 3 is assembled between the two L-shaped pawls 11. Both ends of the binding wire 3 are fixed with connecting ends 12. The interior of the connecting ends 12 is slidably connected to the L-shaped pawls 11. Several meshing teeth 8 are fixed to one end of the rotating shaft 13. A pawl 5 is rotatably connected to one end of the rotating shaft 13, and one end of the pawl 5 engages with the meshing teeth 8.
[0026] In use, one end of the automotive wiring harness is passed through the inner sides of the fixed shaft 2 and the rotating shaft 13, and then the binding wire 3 is used to wrap different numbers and thicknesses of automotive wiring harnesses. The connecting ends 12 of the binding wire 3 then engage with the L-shaped claws 11. Rotating the hand claw 4 causes the rotating shaft 13 to rotate and connect with the guide ring 9, causing the rotating shaft 13 to rotate one of the L-shaped claws 11 and one end of the binding wire 3. This allows the binding wire 3 to tighten different numbers and thicknesses of automotive wiring harnesses. When the automotive wiring harnesses of different thicknesses are tightened to a certain extent, the pawl 5 engages with the meshing teeth 8, effectively preventing the shaft 13 from reversing and avoiding the binding wire 3 from becoming loose. The hand-operated pawl 4 drives the shaft 13 and the meshing teeth 8 to tighten the binding wire 3. At this time, the pawl 5 slides with the meshing teeth 8. When the pawl 5 and the meshing teeth 8 slide to the designated position, the pawl 5 effectively limits the meshing teeth 8, so as to improve the stability of the binding wire 3 in binding automotive wiring harnesses of different quantities and thicknesses.
[0027] Guide grooves 10 are provided at both ends of the inner outer side of the rotating shaft 13, and guide rings 9 are fixed at both ends of the other fixing plate 1. The inner side of the guide rings 9 is rotatably connected to the guide grooves 10.
[0028] The guide ring 9 is rotatably connected to the guide groove 10 to improve the stability of the rotation of the rotating shaft 13 and to serve as a guide rail.
[0029] A spring 7 is fixed to the bottom end of the pawl 5, and a limit block 6 is fixed to the bottom end of the spring 7. One end of the limit block 6 is fixed to another fixing piece 1. The elasticity of the spring 7 effectively keeps the pawl 5 in contact with the meshing teeth 8. When the hand pawl 4 is rotated to drive the rotating shaft 13 to tighten the binding wire 3, the pawl 5 slides with the meshing teeth 8. When it is tightened to the appropriate position, the stress of the binding wire 3 will cause the rotating shaft 13 to reverse. The pawl 5 effectively prevents the rotating shaft 13 and the meshing teeth 8 from reversing, avoiding the binding wire 3 from becoming loose for different numbers and thicknesses of automotive wiring harnesses.
