[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 3 and Figure 4 As shown, this utility model proposes a quick-connect automotive wiring harness assembly, including a connector 1. One end of the connector 1 is fixedly connected to an insert head 21. A recessed head 22 is fitted onto the outside of the insert head 21. A positioning plug 2 is fixedly connected to the end of the recessed head 22 away from the insert head 21. The connection between the insert head 21 and the recessed head 22 allows communication between the connector 1 and the positioning plug 2. A connecting tube 4 is fixedly connected to the outside of the connector 1 near the insert head 21. A protective tube 3 abuts against the end of the connecting tube 4 away from the connector 1. The end of the protective tube 3 away from the connecting tube 4 is fixedly connected to... At the end of the positioning plug 2 near the recessed head 22, the protective tube 3 and the connecting tube 4 are closed to seal and protect the connection position between the embedded head 21 and the recessed head 22. The protective tube 3 has a positioning groove 7 inside, and there are two sets of positioning grooves 7 arranged symmetrically. An embedded block 6 is embedded in the positioning groove 7. An adjusting rod 5 is fixedly connected to the side of the embedded block 6 away from the positioning groove 7. The adjusting rod 5 drives the embedded block 6 to be embedded into the positioning groove 7. The position of the adjusting rod 5 away from the embedded block 6 is set inside the connecting tube 4. The connection of the adjusting rod 5 can make the connection between the protective tube 3 and the connecting tube 4 more stable.

[0025] like Figures 1-3As shown, a rotating shaft 8 is rotatably connected to the inner side of the connecting pipe 4. The rotating shaft 8 is fixedly connected to the outside of the adjusting rod 5. The rotating shaft 8 allows the adjusting rod 5 to rotate, thereby ensuring that the embedded block 6 is embedded in the positioning groove 7. An adjusting assembly is provided on the outside of the connecting pipe 4 near the adjusting rod 5. The adjusting assembly includes an adjusting groove 13, which is opened on the outside of the connecting pipe 4 and passes through the pushing block 14. When adjusting, the adjusting rod 5 rotates through the through structure of the adjusting groove 13. A sealing sleeve 23 is fixedly connected to the outside of the pushing block 14. 3 is fitted into the outside of the protective tube 3. The sealing sleeve 23 can seal the closed protective tube 3 and the connecting tube 4. One end of the rotating shaft 8 has a rotating groove 9. A connecting block 12 is fixedly connected inside the rotating groove 9. A worm spring 10 is fixedly connected outside the connecting block 12. A rotating rod 11 is fixedly connected to one end of the worm spring 10 near the inside. The worm spring 10 can be wound up and reset outside the recessed head 22 and inside the rotating groove 9. The rotating rod 11 is fixedly connected inside the connecting tube 4. The connecting tube 4 is fixed, so the elasticity of the worm spring 10 can drive the rotating shaft 8 to rotate.

[0026] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a push block 14 is slidably connected inside the adjusting groove 13. One end of the connecting pipe 4 abuts against one side of the adjusting rod 5. The push block 14 slides inside the adjusting rod 5 to control whether the adjusting rod 5 drives the embedded block 6 to disengage from the positioning groove 7, or whether the adjusting rod 5 controls the embedded block 6 to be embedded in the positioning groove 7. A pushing component is provided at the end of the push block 14 away from the adjusting rod 5. The pushing component includes a spring 17, which is fixedly connected to the end of the push block 14 away from the adjusting rod 5. A positioning block 18 is fixedly connected to the end of the spring 17 away from the push block 14. The spring 17 can push the push block 14 to one side of the positioning block 18 to control whether the push block 14 is in contact with the adjusting rod 5. One end of the spring 17 is fixedly connected to a telescopic rod 20, which is slidably connected inside the positioning block 18. The telescopic rod 20 can restrict the movement of the pushing block 14 and the extension and retraction of the spring 17. A rotating ring 15 is provided on the outside of the positioning block 18, and a threaded groove 16 is provided on the outside of the connecting pipe 4. The rotating ring 15 is rotatably connected to the outside of the threaded groove 16. The rotating ring 15 can move outside the threaded groove 16 by relying on the threaded groove 16. A sliding groove 19 is provided near the positioning block 18 of the rotating ring 15, and the positioning block 18 is slidably connected inside the sliding groove 19. The sliding of the positioning block 18 inside the sliding groove 19 ensures the stability of the rotating ring 15 when it moves.

[0027] In this embodiment, during connection, the rotating ring 15 is rotated, allowing the adjusting rod 5 to move along the threaded groove 16, thereby moving the rotating ring 15 to a position close to the sealing sleeve 23. The spring 17 will then push the pushing block 14 on the side of the positioning block 18 to squeeze the adjusting rod 5, so that the adjusting rod 5 can be smoothly inserted into the protective tube 3 along with the connecting tube 4. Then, the protective tube 3 and the connecting tube 4 are aligned, and the protective tube 3 is inserted into the sealing sleeve 23, so that the insert head 21 is also inserted into the recessed head 22. In this way, the connecting plug 1 and the positioning plug 2 are connected.

[0028] After connection, rotate the rotating ring 15 to move away from the sealing sleeve 23. This causes the pushing block 14 to slide along one side of the adjusting rod 5. When the pushing block 14 slides to another position, the adjusting rod 5 will rotate along the rotating shaft 8, causing the adjusting rod 5 to drive the embedding block 6 to embed into the positioning groove 7, thereby reinforcing the connection between the protective tube 3 and the connecting tube 4. When the rotating ring 15 rotates, the pushing block 14 is connected to the positioning block 18 through the telescopic rod 20, allowing the positioning block 18 to slide inside the sliding groove 19, thereby allowing the rotating ring 15 to move stably, and the pushing block 14 will also move accordingly.

[0029] The spring 17 pushes the push block 14, keeping the push block 14 in contact with one side of the adjusting rod 5. This ensures the stability of the adjusting rod 5 driving the embedded block 6 into the positioning groove 7. The worm spring 10 inside the rotating groove 9 also relies on the fixing of the rotating rod 11 and the connecting block 12 to ensure that the rotating shaft 8 drives the adjusting rod 5 to tilt up, so that the embedded block 6 is stably embedded into the positioning groove 7.

[0030] When the insert head 21 and the recessed head 22 are connected, the sealing sleeve 23 can also cover the gap between the protective tube 3 and the connecting tube 4, providing sufficient sealing to ensure that no liquid enters the interior of the protective tube 3 and the connecting tube 4, thus ensuring the stability of the connection between the insert head 21 and the recessed head 22.

[0031] During disassembly, simply rotate the rotating ring 15 to move the pushing block 14 closer to the position of the adjusting rod 5 and the fixed embedding block 6. This will cause the pushing block 14 to press down on the adjusting rod 5, which will then move up and down inside the adjusting groove 13, allowing the embedding block 6 to disengage from the positioning groove 7. This will allow the protective tube 3 to be removed from the sealing sleeve 23, thus separating the embedded head 21 and the recessed head 22 fixed to the connector 1, enabling the line to be inspected and repaired.

[0032] It should be noted that this device uses a push block 14 that slides inside the adjustment groove 13, which allows the push block 14 to adjust the position and angle of the adjustment rod 5 inside the adjustment groove 13. In addition, the worm spring 10 inside the rotation groove 9 can also improve the stability of the adjustment rod 5 driving the embedding block 6 to embed into the positioning groove 7. This avoids the problem of fixing the connecting plug 1 and the positioning plug 2 by embedding the locking block into the groove, which requires a lot of force to separate the connecting plug 1 and the positioning plug 2 during disassembly and maintenance. This improves the convenience of disassembling and assembling the connecting plug 1 and the positioning plug 2.

[0033] The above specific embodiments are merely several optional 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.
