Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive wiring harness technology, and more specifically, to a wear-resistant automotive wiring harness. Background Technology
[0002] Automotive wiring harnesses are the main network components of automotive circuits. They consist of copper-plated contact terminals (connectors) crimped to wires and cables, then covered with plastic insulation or an outer metal shell, and bundled together to form a circuit connection. Automotive wiring harnesses connect different electrical components together, and their safety directly affects the normal operation of automotive electrical components and driving safety.
[0003] In response, Chinese patent application number CN202420615587.6 discloses a wear-resistant automotive wiring harness, comprising a wiring harness body with connector terminals at both ends. The wiring harness body includes multiple sets of wires, each wire consisting of an outer sheath and a core, with the outer sheath covering the core. Multiple sets of elastic anti-wear protrusions are provided on the outer surface of the outer sheath. A limiting member is provided in the middle of the wiring harness body, with elastic telescopic sleeves at both ends of the limiting member. The multiple sets of elastic anti-wear protrusions of this invention first contact the object, providing a blocking and protective function. When the wires move, the elastic anti-wear protrusions rub against the base surface, preventing friction from directly acting on the outer sheath. Multiple sets of circular slots in the limiting member limit the multiple sets of wires, preventing entanglement and twisting between the wires and reducing friction between them. The multiple sets of wires are placed inside the elastic telescopic sleeves, which protect the wires and improve the wear resistance of the automotive wiring harness.
[0004] The device can protect the wires from the outside by setting up an elastic telescopic sleeve. However, the elastic telescopic sleeve is only fixed to the outside of the connector terminal by an elastic ring. The surface of the connector terminal is smooth. When the elastic telescopic sleeve slides off the connector terminal, it will cause the elastic telescopic sleeve to roll up, thus failing to provide comprehensive protection for the wires, resulting in the wires being damaged by abrasion from foreign objects.
[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a wear-resistant automotive wiring harness. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wear-resistant automotive wiring harness.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A wear-resistant automotive wiring harness includes: a first connector, the surface of which is connected to a second connector via a wire;
[0009] The surfaces of the first connector and the second connector are provided with grooves;
[0010] The first connector and the second connector are equipped with a protective structure on their outer side. The protective structure includes a fixing block, which is fixedly installed on the outer wall of the first connector and the second connector. A connecting block is rotatably connected to the end of the fixing block. A coil spring is provided at the connection between the fixing block and the connecting block. A clamping plate is fixedly connected to the end of the connecting block. A wear-resistant sleeve is provided on the outer side of the wire. Rubber bands are inserted inside both ends of the wear-resistant sleeve.
[0011] Preferably, the surfaces of the first connector and the second connector are respectively provided with two sets of retaining plates, and the two sets of retaining plates are symmetrically installed vertically.
[0012] Preferably, the length of the wear-resistant sleeve is greater than the length of the wire, and the two ends of the wear-resistant sleeve are respectively fitted onto the outside of the first connector and the wire.
[0013] Preferably, the elastic band is placed inside the groove.
[0014] Preferably, the inner wall of the card plate fits against the outer walls of the first connector and the second connector, and covers the outside of the groove.
[0015] Preferably, the inner wall of the card plate is fitted to the outer wall of the end of the wear-resistant sleeve.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] In this invention, grooves are provided on the surfaces of the first and second connectors to provide a stable mounting position for the elastic band. During installation, the wear-resistant sleeve and the elastic band are placed on the outside of the wire. Then, the locking plate is pulled, causing the connecting block to rotate on the fixing block, exposing the inside of the groove. A coil spring is provided between the connecting block and the fixing block, allowing it to elastically deform when the connecting block rotates on the fixing block. Next, the wear-resistant sleeve is pulled, placing both ends of the sleeve on the outside of the first and second connectors respectively, thus securing the elastic band inside the groove. This ensures the wear-resistant sleeve remains stable on the outer walls of the first and second connectors. Finally, the locking plate is released, and it resets under the elastic action of the coil spring, pressing against the outside of the end of the wear-resistant sleeve. This further secures the end of the wear-resistant sleeve to the outer walls of the first and second connectors, ensuring stable installation at both ends. Consequently, the wear-resistant sleeve provides stable protection for the wire from the outside, preventing damage from direct friction with external objects and extending the service life of the device.

[0024] Please see Figures 1-4 This utility model provides an embodiment of a wear-resistant automotive wiring harness:
[0025] The first connector 1, wire 11 and the second connector 12 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.
[0026] A wear-resistant automotive wiring harness includes: a first connector 1, and a second connector 12 connected to the surface of the first connector 1 via a wire 11;
[0027] The surfaces of the first connector 1 and the second connector 12 are provided with grooves 13;
[0028] A protective structure 2 is installed on the outer side of the first connector 1 and the second connector 12. The protective structure 2 includes a fixing block 21, which is fixedly installed on the outer wall of the first connector 1 and the second connector 12. A connecting block 22 is rotatably connected to the end of the fixing block 21. A coil spring 23 is provided at the connection between the fixing block 21 and the connecting block 22. A retaining plate 24 is fixedly connected to the end of the connecting block 22. A wear-resistant sleeve 25 is fitted on the outer side of the wire 11. Rubber bands 26 are inserted inside both ends of the wear-resistant sleeve 25. Grooves 13 are formed on the surface of the first connector 1 and the second connector 12 to provide a position for the stable installation of the rubber bands 26 on the first connector 1 and the second connector 12. During installation, the wear-resistant sleeve 25 and the rubber bands 26 are fitted on the outer side of the wire 11. Then, the retaining plate 24 is pulled, which causes the connecting block 22 to rotate on the fixing block 21, allowing the inner side of the groove 13 to be exposed. A coil spring 23 is provided between the connecting block 22 and the fixing block 21. The coil spring 23 can elastically deform when the connecting block 22 rotates on the fixing block 21. Then, the wear-resistant sleeve 25 is pulled, and the two ends of the wear-resistant sleeve 25 are respectively fitted onto the outside of the first connector 1 and the second connector 12. The rubber band 26 is then clamped on the inside of the groove 13, which can make the wear-resistant sleeve 25 stable on the outer wall of the first connector 1 and the second connector 12. Finally, the locking plate 24 is released, and the locking plate 24 is reset under the elastic action of the coil spring 23. The locking plate 24 can then press on the outside of the end of the wear-resistant sleeve 25, which can further fix the end of the wear-resistant sleeve 25 on the outer wall of the first connector 1 and the second connector 12. This allows the two ends of the wear-resistant sleeve 25 to be stably installed. In this way, the wear-resistant sleeve 25 can stably protect the wire 11 from direct friction with external objects and damage, thus extending the service life of the device.
[0029] Furthermore, the surfaces of the first connector 1 and the second connector 12 are respectively provided with two sets of clamping plates 24. The two sets of clamping plates 24 are installed symmetrically from top to bottom. The two sets of clamping plates 24 can fix the ends of the wear-resistant sleeve 25 to the outside of the first connector 1 and the second connector 12 from the top and bottom sides, thereby enhancing the installation stability of the wear-resistant sleeve 25 and ensuring the protection effect on the wire 11.
[0030] Furthermore, the length of the wear-resistant sleeve 25 is greater than the length of the wire 11. The two ends of the wear-resistant sleeve 25 are respectively fitted on the outside of the first connector 1 and the wire 11. When the wear-resistant sleeve 25 is fitted on the outside of the wire 11, the two ends of the wear-resistant sleeve 25 can be located on the outside of the first connector 1 and the second connector 12, so that the clamping plates 24 on the first connector 1 and the second connector 12 can clamp and fix the wear-resistant sleeve 25.
[0031] Furthermore, the elastic band 26 is clamped inside the groove 13, which provides a connection for the installation of the elastic band 26 on the outside of the first connector 1 and the second connector 12, ensuring the stability of the elastic band 26 in fixing the wear-resistant sleeve 25.
[0032] Furthermore, the inner wall of the clamping plate 24 fits against the outer wall of the first connector 1 and the second connector 12, and covers the outer side of the groove 13. The clamping plate 24 can limit the rubber band 26 in the groove 13 from the outside, further preventing the rubber band 26 from detaching from the groove 13, thereby ensuring the fixing effect of the wear-resistant sleeve 25.
[0033] Furthermore, the inner wall of the clamping plate 24 fits against the outer wall of the end of the wear-resistant sleeve 25. The clamping plate 24 can clamp the wear-resistant sleeve 25 on the outside of the first connector 1 and the second connector 12, so as to make the installation of the wear-resistant sleeve 25 stable and improve the performance of the wear-resistant sleeve 25.
[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
