Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4 This embodiment provides an automotive wiring harness that is easy to disassemble and repair, comprising a wiring harness body 1 and two automotive mounting panels 2 respectively installed at the upper and lower ends of the wiring harness body 1.

[0025] A protective tube 3 is fitted onto the outer peripheral wall of the wire harness body 1. A fixing component 4 is provided on the protective tube 3. During use, the wire harness body 1 is fixedly connected to the vehicle mounting panel 2 via a plug-in or other installation method. The fixing component 4 then secures the protective tube 3 to the vehicle mounting panel 2. The protective tube 3 thus provides dust protection for the wire harness body 1. The fixing component 4 is a reversible structure; when the wire harness body 1 needs to be disassembled for maintenance, disassembly can be completed quickly without damaging the device. This facilitates reinstallation after maintenance, improving practicality and making it easier to promote and use. A protective component 5 is provided on the outer peripheral wall of the protective tube 3. The protective component 5 ensures the transmission effect of the wire harness body 1 and also increases the anti-collision, flame-retardant, and wear-resistant properties of the protective tube 3, further enhancing the protective effect of the protective tube 3 on the wire harness body 1, resulting in better protection for the wire harness body 1.

[0026] Please see Figure 1-4The fixing component 4 includes two fixing rings 401 respectively fixed to the opposite sides of the two car fixing panels 2. Both the upper and lower ends of the protective tube 3 are fixed with sleeve rings 402. Multiple movable grooves 403 are formed in the peripheral wall of the sleeve ring 402, and an annular groove 406 is formed on the outer peripheral wall of the fixing ring 401. When installing the protective tube 3, after the wiring harness body 1 is installed, the sleeve ring 402 is fitted onto the outer peripheral wall of the fixing ring 401, and the movable grooves 403 on the sleeve ring 402 are aligned with the annular grooves 406 on the fixing ring 401. The groove 406 is flush with the outer peripheral wall of the sleeve ring 402, and a compression ring 407 is threaded onto the outer peripheral wall. Multiple circular holes 404 communicating with the movable groove 403 are provided on both the inner and outer peripheral walls of the sleeve ring 402. A ball bearing 405 is slidably connected within the movable groove 403. The multiple movable grooves 403 are equidistantly distributed along the circumference of the sleeve ring 402. The diameter of the circular holes 404 is smaller than the diameter of the ball bearing 405. The movable groove 403 allows the ball bearing 405 to slide within it along the diametrical direction of the sleeve ring 402. The outer peripheral wall of the connecting ring 402 is provided with an external threaded groove 408, and the inner peripheral wall of the extrusion ring 407 is provided with an internal threaded groove 409 that matches the external threaded groove 408. The inner peripheral wall of the extrusion ring 407, especially the side closest to the vehicle mounting panel 2, is tapered. Furthermore, by rotating the extrusion ring 407, the extrusion ring 407 moves along the outer peripheral wall of the connecting ring 402 through the engagement of the external threaded groove 408 and the internal threaded groove 409. When the extrusion ring 407 moves to the movable groove 403, the inner peripheral wall of the extrusion ring 407 is extruded. Press the ball bearing 405 so that it moves towards the fixed ring 401 inside the movable groove 403, and a small part of the ball bearing 405 passes through the circular hole 404 and gets into the annular groove 406 to achieve the effect of fixing the sleeve ring 402 and the fixed ring 401, thus completing the installation. When it is necessary to disassemble and repair the main body 1 of the wire harness, reverse the compression ring 407 so that it no longer compresses the ball bearing 405. At this time, the ball bearing 405 can move away from the fixed ring 401 inside the movable groove 403 and get out of the annular groove 406, thus completing the disassembly.

[0027] The fixing ring 401, the sleeve ring 402, the annular groove 406, and the compression ring 407 are all located on the same central axis. The fixing ring 401 is inserted into the sleeve ring 402 and is slidably connected to it.

[0028] Please see Figure 5In this embodiment, the protective component 5 includes a shielding layer 501 fixed on the inner peripheral wall of the protective tube 3. The shielding layer 501 can effectively shield the interference of external signals to the internal signals of the wire harness body 1, thereby ensuring the transmission effect of the wire harness body 1. A buffer layer 502 is fixed on the outer peripheral wall of the protective tube 3. The buffer layer 502 can buffer impacts and prevent external impacts from damaging the wire core of the wire harness body 1 and affecting transmission. A flame-retardant layer 503 is fixed on the outer peripheral wall of the buffer layer 502. The flame-retardant layer 503 can improve the flame-retardant characteristics of the protective tube 3, thereby preventing the wire harness body 1 from being burned. A wear-resistant layer 504 is fixed on the outer peripheral wall of the flame-retardant layer 503. The wear-resistant layer 504 can improve the wear resistance of the protective tube 3, thereby increasing the service life of the protective tube 3.

[0029] The shielding layer 501 is a metal wire woven mesh layer. Metal wire woven mesh refers to a metal screen surface made of metal wires woven together to form a mesh. It has the ability to absorb the energy of electromagnetic waves. When electromagnetic waves come into contact with the metal mesh, some of the energy will be absorbed by the metal mesh, converted into heat energy, and prevented from continuing to propagate, thus achieving the effect of shielding external signals. The buffer layer 502 is a honeycomb elastic rubber pad layer. The flame retardant layer 503 is a flame retardant polypropylene coating. The inorganic filler flame retardant polypropylene refers to aluminum hydroxide and magnesium hydroxide, which have flame retardant and smoke-suppressing effects. The wear-resistant layer 504 is an ABS resin coating. ABS plastic has the combined properties of the three components, with excellent comprehensive physical and mechanical properties, good low-temperature impact resistance, dimensional stability, electrical properties, and wear resistance.

[0030] The working principle of the above embodiments is as follows:

[0031] (1) When installing the protective tube 3, after the main body 1 of the wire harness is installed, the sleeve ring 402 is placed on the outer peripheral wall of the fixed ring 401, and the movable groove 403 on the sleeve ring 402 is flush with the annular groove 406 on the fixed ring 401. Then, the compression ring 407 is rotated. The compression ring 407 moves along the outer peripheral wall of the sleeve ring 402 through the cooperation of the external thread groove 408 and the internal thread groove 409. When the compression ring 407 moves to the movable groove 403, the inner peripheral wall of the compression ring 407 compresses the roller. The ball 405 moves inside the movable groove 403 toward the fixed ring 401, and a small part of the ball 405 passes through the circular hole 404 and gets into the annular groove 406 to achieve the effect of fixing the sleeve ring 402 and the fixed ring 401, thus completing the installation. When it is necessary to disassemble and repair the main body 1 of the wire harness, the reverse compression ring 407 is reversed so that it no longer compresses the ball 405. At this time, the ball 405 can move inside the movable groove 403 toward the side away from the fixed ring 401 and get out of the annular groove 406, thus completing the disassembly.

[0032] (2) The shielding layer 501 can effectively shield the interference of external signals to the internal signals of the wire harness body 1, thereby ensuring the transmission effect of the wire harness body 1. The buffer layer 502 can buffer the impact, preventing external impact from damaging the wire core of the wire harness body 1 and affecting the transmission. The flame retardant layer 503 can improve the flame retardant characteristics of the protective tube 3, thereby preventing the wire harness body 1 from being burned. The wear-resistant layer 504 can improve the wear resistance of the protective tube 3, thereby improving the service life of the protective tube 3.
