Description

Technical Field

[0001] This utility model relates to the field of wiring harness technology, specifically to an automotive wiring harness that is easy to disassemble and repair. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits, and their role is crucial. They not only supply power to devices such as lights, audio systems, air conditioning, and electronic control systems, but also ensure accurate and stable data transmission between components such as sensors and actuators.

[0003] Existing automotive wiring harnesses often lack proper positioning and insertion of connectors and plugs, leading to misalignment and damage during connection. Furthermore, the connectors and plugs are difficult to separate due to their interlocking connection, potentially causing the wiring harness to detach and become detached. This hinders the disassembly and maintenance of automotive wiring harnesses. Therefore, we propose an automotive wiring harness that facilitates disassembly and maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive wiring harness that is easy to disassemble and repair. It has the advantages of facilitating the positioning and plugging of automotive wiring harness connectors and joints, and also facilitating the disassembly of automotive wiring harnesses, thereby making automotive wiring harness repair easier. It solves the problems in existing automotive wiring harnesses where connectors and joints cannot play a positioning and plugging role during connection, which can easily lead to damage due to misalignment during connection. Furthermore, when disassembling connectors and joints, separation is difficult because they are plugged together, and the wiring harness can easily be pulled and cause the wiring harness on the connectors and joints to fall off, making it inconvenient for the disassembly and repair of automotive wiring harnesses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive wiring harness that is easy to disassemble and repair, comprising a connector and a joint. A fixing plate is installed on the outside of the connector, and a wiring harness A is connected to the outside of the fixing plate. Connecting plates are installed on both the front and rear surfaces of the fixing plate. Sliding strips are provided at opposite ends of the two connecting plates. J-shaped hook plates are connected to the ends of the two connecting plates via a pivot. A plug groove is provided on the inside of the joint. A wiring harness B is connected to the outside of the joint. A protruding plate is provided on both the front and rear surfaces of the joint. A sliding groove is provided at opposite ends of the two protruding plates. A helical spring is provided inside the two sliding grooves. A fixing groove is provided on the outer surface of the two protruding plates near the wiring harness B.

[0006] Preferably, each of the two J-shaped hook plates has a receiving groove on the side of its outer surface near the connector, and each of the two receiving grooves has a V-shaped spring piece installed inside. When wire harness A and wire harness B are disassembled, pressing the connector causes the end of the J-shaped hook plate to separate from the fixing groove. The compressed V-shaped spring piece then acts on the J-shaped hook plate, causing the J-shaped hook plate to rotate and move away from the fixing groove and the protrusion plate.

[0007] Preferably, notches are provided on both the upper and lower surfaces of the connector near the inner side, and rotating plates are installed inside the two notches. After the connector and the plug are connected, the rotating plates rotate into the gap between the fixed plate and the connector, which restricts the movement of the fixed plate, the connecting plate and the J-shaped hook plate, thereby preventing the J-shaped hook plate from slipping out of the fixed groove.

[0008] Preferably, both rotating plates have protruding locking strips on their inner sides, and the fixing plate has locking grooves on its inner side near its upper and lower surfaces. The rotating plates are fixed after the protruding locking strips are inserted into the locking grooves.

[0009] Preferably, a sealing ring is installed on the inner wall of the insertion slot, and a step is provided on the inner side of the fixing plate. After the plug is inserted into the insertion slot, the sealing ring is squeezed by the step and plays a sealing role.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting up wire harness A, a fixing plate, a connector, a connector groove, wire harness B, a protruding plate, a sliding groove, a helical spring, a fixing groove, a connecting plate, a sliding strip, and a J-shaped hook plate, achieves the effect of facilitating the positioning and insertion connection of automotive wire harness connectors and joints, and also facilitates the disassembly of automotive wire harnesses, thereby facilitating the maintenance of automotive wire harnesses. When wire harness A and wire harness B are connected, the two sliding strips are first inserted into the two sliding grooves respectively. As the sliding strips slide into the sliding grooves, the helical spring is compressed, and at the same time, the connector is inserted into the connector groove, thus providing a positioning and insertion function for the connection of the connector and joint. Then, the J-shaped hook plate is rotated to... When the J-shaped hook plate and the connecting plate are flush and the end of the J-shaped hook plate is close to the fixed groove, after releasing the fixed plate, the compressed helical spring is released, and the connecting plate and the J-shaped hook plate are moved by the sliding bar, so that the end of the J-shaped hook plate is inserted into the fixed groove, thus completing the connection between the connector and the plug. When disassembling wire harness A and wire harness B, press the plug to separate the end of the J-shaped hook plate from the fixed groove, then rotate the J-shaped hook plate away from the protrusion plate, the compressed helical spring is released, and the fixed plate is pushed away from the connector by the sliding bar and the connecting plate, so that the plug is moved out of the plug groove, so as to facilitate the disassembly between the plug and the connector.

[0012] 2. This utility model achieves the effect of facilitating the separation of the J-type hook plate and the fixing groove by setting a receiving groove and a V-shaped spring piece. When disassembling wire harness A and wire harness B, pressing the connector separates the end of the J-type hook plate from the fixing groove. The compressed V-shaped spring piece then acts on the J-type hook plate, causing the J-type hook plate to rotate and move away from the fixing groove and the protrusion plate.

[0013] 3. This utility model achieves the effect of preventing the J-shaped hook plate from slipping out of the fixed groove by setting a rotating plate, notch, protruding locking strip and locking groove. After the connector and plug are connected, the rotating plate rotates into the gap between the fixed plate and the connector, and the rotating plate is fixed by the protruding locking strip and locking groove, which restricts the movement of the fixed plate, connecting plate and J-shaped hook plate, thereby preventing the J-shaped hook plate from slipping out of the fixed groove.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0020] like Figures 1-4As shown, this utility model proposes an automotive wiring harness that is easy to disassemble and maintain, including a connector 3 and a connector 4. A fixing plate 2 is installed on the outside of the connector 3, and a wiring harness A1 is connected to the outside of the fixing plate 2. Connecting plates 7 are installed on both the front and rear surfaces of the fixing plate 2. Sliding strips 10 are provided at opposite ends of the two connecting plates 7. The sliding strips 10 and the connecting plates 7 are integrally formed. J-shaped hook plates 12 are connected to the ends of the two connecting plates 7 through a pivot 11. A plug groove 15 is provided on the inside of the connector 4, and a wiring harness is connected to the outside of the connector 4. B5, both the front and rear surfaces of the connector 4 are provided with raised plates 6, which are integrally formed with the connector 4. Each of the two raised plates 6 has a sliding groove 20 at one end facing away from each other. Both sliding grooves 20 are provided with a helical spring 21 inside. The outer surface of the two raised plates 6 is provided with a fixing groove 22 on the side near the wire harness B5. A sealing ring 16 is installed on the inner wall of the plug groove 15. A step 9 is provided on the inner side of the fixing plate 2. After the plug 3 is inserted into the plug groove 15, the sealing ring 16 is squeezed by the step 9 and plays a sealing role.

[0021] In this embodiment, when wire harness A1 and wire harness B5 are connected, the two sliding bars 10 are first inserted into the two sliding grooves 20 respectively. As the sliding bars 10 slide into the sliding grooves 20, the helical spring 21 is compressed. At the same time, the plug 3 is inserted into the plug slot 15, which plays a role in positioning and plugging the plug 3 and the connector 4. Then, the J-shaped hook plate 12 is rotated so that the J-shaped hook plate 12 is flush with the connecting plate 7, and the end of the J-shaped hook plate 12 is close to the fixed groove 22. After the fixed plate 2 is released, the compressed helical spring 21 is released, and the sliding bars 10 drive the connecting plate 7 and the connector 4 to connect. The J-shaped hook plate 12 moves so that its end is inserted into the fixing groove 22, thus completing the connection between the connector 4 and the plug 3. When disassembling the wiring harness A1 and the wiring harness B5, pressing the plug 3 separates the end of the J-shaped hook plate 12 from the fixing groove 22. Then, the J-shaped hook plate 12 is rotated and moved away from the protrusion plate 6. The compressed coil spring 21 is released and pushed away from the connector 4 by the sliding bar 10 and the connecting plate 7, thus moving the plug 3 out of the plug groove 15. This facilitates the disassembly of the plug 3 and the connector 4, which is convenient for the maintenance of the automotive wiring harness. Example 2

[0022] like Figures 1-4 As shown, the present invention proposes an automotive wiring harness that is easy to disassemble and repair. Compared with the first embodiment, this embodiment also includes two J-shaped hook plates 12 with receiving grooves 14 on the outer surface near the plug 3, and V-shaped spring pieces 13 are installed inside the two receiving grooves 14.

[0023] In this embodiment, when wire harness A1 and wire harness B5 are disassembled, pressing the connector 3 causes the end of the J-shaped hook plate 12 to separate from the fixing groove 22. Then, the compressed V-shaped spring 13 acts on the J-shaped hook plate 12, causing the J-shaped hook plate 12 to rotate and move away from the fixing groove 22 and the protrusion plate 6. Example 3

[0024] like Figures 1-4 As shown, the present invention proposes an automotive wiring harness that is easy to disassemble and repair. Compared with Embodiment 1, this embodiment also includes notches 17 on the upper and lower surfaces of the connector 4 near the inner side. Rotating plates 18 are installed inside the two notches 17. The rotating plates 18 are installed inside the notches 17 via rotating shafts. Protruding retaining strips 19 are provided on the inner side of the two rotating plates 18. Snap-fit ​​grooves 8 are provided on the inner side of the fixing plate 2 near the upper and lower surfaces.

[0025] In this embodiment, after the connector 4 and the plug 3 are connected, the rotating plate 18 rotates into the gap between the fixed plate 2 and the connector 4, and the rotating plate 18 is fixed by the protruding locking strip 19 and the locking groove 8, which restricts the movement of the fixed plate 2, the connecting plate 7 and the J-shaped hook plate 12, thereby preventing the J-shaped hook plate 12 from slipping out of the fixed groove 22.

[0026] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
