[0024] The following is combined with Figure 1-5 The present invention is described in further detail.
[0025] The embodiment of the present invention discloses a quick plug-in connection structure for an automobile wiring harness. Figure 1-Figure 3 , including a base frame 1, a connecting frame 9 is fixed to the middle of the back wall of the base frame 1, and a movable support plate 2 and a fixed support plate 10 are staggered on the connecting frame 9. A group of support blocks 12 and top blocks 16 are evenly distributed on the inner wall of the end where the movable support plate 2 and the fixed support plate 10 are close to each other, and the inner walls of the support blocks 12 and the top blocks 16 are both provided with arc grooves. The arc grooves on the inner walls of the support blocks 12 and the top blocks 16 on the movable support plate 2 and the fixed support plate 10 precisely fit the contour of the wiring harness, provide initial stable support, and prevent the wiring harness from shaking. A support assembly is provided between the movable support plate 2 and the fixed support plate 10, and the support assembly includes a sliding rod 8 fixed to the edge of the movable support plate 2, a guide frame 6 adapted to the sliding rod 8, and a connecting piece 13 and a connecting piece 2 14. The top of the guide frame 6 is fixed to the edge of the fixed support plate 10, and a guide groove 7 is provided inside the guide frame 6. One end of the sliding rod 8 extends outside the guide groove 7 and is fixed with an anti-slip block 11. The slide rod 8 cooperates with the guide groove 7 of the guide frame 6, allowing the movable support plate 2 to slide relative to the fixed support plate 10. Combined with the limiting design of the anti-slip block 11, it can quickly adapt to the clamping requirements of wire harnesses of different diameters. It can complete the fixation of wire harnesses of multiple specifications without replacing parts, thereby improving the versatility of the production line.
[0026] In this application, connector 2 14 is fixed to the inner wall of movable support plate 2, while connector 1 13 is fixed to the inner wall of fixed support plate 10. Connector 2 14 is sleeved onto the exterior of connector 1 13. A support spring 15 is connected between connector 2 14 and the adjacent inner wall of connector 1 13. Support spring 15 connects connector 1 13 and connector 2 14, allowing movable support plate 2 to automatically adjust its clamping force according to the thickness of the wiring harness, ensuring effective clamping while preventing excessive compression and damage to the wiring harness, thereby improving compatibility and protection.
[0027] like Figure 4 As shown, a support arm 4 is fixed to the front end of the base frame 1, and a group of plug-in support frames 3 are equidistantly provided on the inner wall of the support arm 4. An adjustable shift rod 24 is provided on the plug-in support frame 3, and a plug-in assembly is provided at the bottom of the shift rod 24. The plug-in assembly includes a plug-in block 20 and a limiting protrusion 23. A connecting rod 5 is connected between the base frame 1 and one of the plug-in support frames 3. A damping groove 17 is provided on the inner wall of the support arm 4, and a matching damping slider is slidably installed in the damping groove 17. The plug-in support frame 3 is connected to the damping groove 17 through the sliding connection of the damping slider and the damping groove 17, and the height and position can be freely adjusted. With the structural support of the connecting rod 5, it can flexibly adapt to complex wiring harness layouts, thereby improving installation efficiency and operational convenience.
[0028] like Figure 5 As shown, the damping slider is fixed to the side wall of the plug support frame 3. A group of equally spaced sockets 18 are provided inside the plug support frame 3 to provide space for the plug block 20 to move. A connecting slot 19 is provided between each adjacent socket 18. A group of equally spaced fixed blocks 26 are fixed to the top of the plug support frame 3. A guide rod 27 is fixed to the middle of the top of the fixed block 26. The inner wall of the fixed block 26 is connected to the arc-shaped second clamp 28. The first clamp 25 and the second clamp 28 are respectively fixed to the plug block 20 and the fixed block 26, which can simultaneously clamp the two sides of the wiring harness, forming a double fixation, further reducing the displacement of the wiring harness during plugging and unplugging.
[0029] In the present application, a set of shifting grooves equidistantly arranged inside the shifting rod 24 are slidably adapted to the guide rod 27. The plug-in block 20 is fixed to the inner wall of the shifting rod 24. A contraction cavity 21 is arranged inside the plug-in block 20. A limiting protrusion 23 is movably adapted to the contraction cavity 21. A spring 22 for support is connected between the limiting protrusion 23 and the inner wall of the contraction cavity 21. A clamp 25 is fixed to the inner wall of the top of the plug-in block 20. The shifting rod 24 cooperates with the guiding of the shifting grooves by the guide rod 27 to ensure that the plug-in block 20 moves smoothly to the target socket 18. The slide groove 19 allows the plug-in block 20 to adjust its position laterally and flexibly adapt to the direction of the wiring harness. The combination of the limiting protrusion 23 and the spring 22 automatically pops out and clamps after the plug-in block 20 is inserted into the socket 18, forming a mechanical lock to prevent loosening and ensure the stability of the connection.
[0030] The implementation principle of a quick plug-in connection structure for an automobile wiring harness according to an embodiment of the present invention is as follows:
[0031] When in use, first fix the chassis 1 in a suitable position. When connecting the automotive wiring harness, the movable support plate 2 and the support block 12 and the top block 16 on the fixed support plate 10 can clamp the wiring harness together. The arc groove on its inner wall is adapted to the shape of the wiring harness, providing stable support, and can preliminarily fix the automotive wiring harness. The support spring 15 on the inner wall of the connector 2 14 provides elastic support for the connector 1 13, so that the movable support plate 2 can adaptively adjust the force when clamping the wiring harness to ensure the clamping effect. The movable support plate 2 slides in the guide groove 7 of the guide frame 6 through the slide bar 8 to achieve movement relative to the fixed support plate 10, adapting to the clamping requirements of wiring harnesses of different sizes. The anti-slip block 11 prevents the slide bar 8 from sliding out of the guide groove 7.
[0032] Then, one end of the wiring harness is passed between adjacent plug-in supports 3. Depending on the diameter of the wiring harness, the shift rod 24 can be manually operated to slide toward one side within the plug-in support 3. At this time, the guide rod 27 engages with the shift groove of the shift rod 24, acting as a guide and ensuring smooth movement of the shift rod 24. The plug-in block 20 engages and moves to the appropriate position in the chute 19. When the plug-in block 20 is inserted into the socket 18, the limit protrusion 23 is activated by the spring 22 to pop out of the retraction cavity 21 and engage the socket 18 to limit the position, ensuring a stable plug-in connection. The clamping distance between the clamp 1 25 and the clamp 2 28 is thus positioned, so that the clamp 1 25 and the clamp 2 28 respectively clamp the two sides of the wiring harness, further fixing the wiring harness position and preventing the wiring harness from shaking during plug-in and unplugging. In addition, the plug-in support 3 slides within the damping chute 17 of the support arm 4 via a damping slider, allowing the position and height of the plug-in support 3 to be adjusted to accommodate different wiring harness layouts, greatly improving the flexibility of the automotive wiring harness connection.
