Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1-Figure 3 and Figure 5 As shown, the existing wiring harness assembly adopts a single plug-in connection method, which makes the line easy to loosen during use. In order to solve this technical problem, the present embodiment discloses the following technical content; a wiring harness assembly with anti-vibration disconnection, including a male seat 1 and a female seat 2 connected to the wiring harness, and the male seat 1 and the female seat 2 are plug-in connected; a connecting sleeve 3 is fixedly provided on the left end of the female seat 2, and a sliding adjustment seat 4 is slidably installed on the outer side of the female seat 2, and a first spring 5 is fixedly connected between the sliding adjustment seat 4 and the female seat 2, elastic positioning pieces 6 are evenly arranged on the outer side of the end of the female seat 2, and a limit adjustment ring 7 is provided on the outer side of the elastic positioning piece 6, a groove structure is opened on the inner side of the sliding adjustment seat 4, and a movable push block 8 is evenly penetrated and telescopically installed on the inner side of the sliding adjustment seat 4.

[0022] The sliding adjustment seat 4 forms an elastic sliding structure with the mother seat 2 under the elastic force of the first spring 5, and during the sliding process of the sliding adjustment seat 4, the movable push block 8 pushes the limit adjustment ring 7 to slide on the outside of the elastic positioning piece 6, and the outer diameter of the limit adjustment ring 7 gradually increases from right to left.

[0023] In the initial state, the left end of the elastic positioning piece 6 is bent and expanded outward, and the limiting adjustment ring 7 is straightened when sliding along the outer side of the elastic positioning piece 6 .

[0024] A locking limit block 601 is fixedly provided on the inner wall of the left end of the elastic positioning piece 6, and the left end of the straightened elastic positioning piece 6 is attached to the outer wall of the male seat 1, and the limit holes 101 are evenly opened on the outer wall of the right end of the male seat 1, and the locking limit block 601 and the limit hole 101 constitute a snap-fit ​​structure.

[0025] By adopting the above technical scheme, when it is necessary to plug the male seat 1 and the female seat 2, the sliding adjustment seat 4 is manually pulled to make the sliding adjustment seat 4 slide along the outer side of the female seat 2 and compress the first spring 5. At this time, the elastic positioning piece 6 will be elastically deformed under the action of its own elasticity, so that its left end is bent and expanded outward, and push the limit adjustment ring 7 to slide to the right side. At this time, the male seat 1 and the female seat 2 can be aligned and plugged. After the plugging is completed, the sliding adjustment seat 4 is released. At this time, the sliding adjustment seat 4 will slide and reset under the elastic force of the first spring 5, and at the same time, the limit adjustment ring 7 is pushed to slide synchronously through the movable push block 8 on its inner side, so that the limit adjustment ring 7 can slide along the outer side of the elastic positioning piece 6, thereby making the elastic positioning piece 6 elastically deformed again. At this time, the left ends of multiple elastic positioning pieces 6 gradually move closer, so that the end of the elastic positioning piece 6 can fit the outer wall of the male seat 1, and at the same time, the locking limit block 601 is automatically inserted into the limit hole 101 at the corresponding position, thereby realizing the wiring locking of the male seat 1 and the female seat 2.

[0026] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. The existing wiring harness assembly lacks a certain shockproof function, which makes it easy to cause the looseness of the wiring harness assembly joint during the bumpy driving of the vehicle, thereby affecting the driving safety of the vehicle. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 4-Figure 8 As shown; a buffer component used to achieve shockproof is fixedly installed below the sliding adjustment seat 4, and the lower end of the buffer component is provided with a clamping piece fixedly connected to the vehicle body, and the inner side of the connecting sleeve 3 is provided with an adsorption component for improving the stability of the connection during vibration.

[0027] The buffer assembly includes a telescopic guide column 9 fixedly installed below the sliding adjustment seat 4, and the lower end of the telescopic guide column 9 is telescopically mounted on a mounting seat 10, and a second spring 11 is fixedly connected between the sliding adjustment seat 4 and the mounting seat 10, and a clamp is fixedly connected to the lower end of the mounting seat 10.

[0029] When the telescopic guide column 9 and the mounting seat 10 are telescopically adjusted, part of the oil in the oil storage bag 12 is transported to the adjusting oil bag 13. After the adjusting oil bag 13 expands, it pushes the movable push block 8 to telescopically adjust. During the telescopic adjustment process, the movable push block 8 pushes the limit adjustment ring 7 to slide on the outside of the elastic positioning piece 6 again.

[0030] A sliding groove is provided on the elastic positioning piece 6, and the adsorption assembly includes a slider 14 slidably installed in the sliding groove, and the limit adjustment ring 7 pushes the slider 14 to slide along the sliding groove when the movable push block 8 pushes it again.

During the movement of the slider 14, the sealing film 15 is pulled by the pull rope 16 to slide on the inner side of the negative pressure groove 301 to generate a negative pressure adsorption effect.

[0032] By adopting the above technical solution, when the wiring harness is installed, the clamping piece arranged at the bottom of the mounting seat 10 is inserted into the preset hole on the vehicle body component, so as to realize the positioning of the wiring harness assembly. When the vehicle is bumped and vibrated during driving, the telescopic guide column 9 and the mounting seat 10 will be telescopically adjusted, so as to realize the shockproof of the connection between the male seat 1 and the female seat 2. At the same time, the telescopic guide column 9 and the mounting seat 10 will squeeze the oil storage bag 12 during the telescopic process, so that part of the oil in the oil storage bag 12 enters the regulating oil bag 13 through the pipeline, so that the regulating oil bag 13 is deformed and expanded, thereby pushing the movable push block 8 on the inner side of the sliding adjustment seat 4 to be telescopically adjusted. At this time, the movable push block 8 will extend toward the limit adjustment ring 7 during the extension process. The inclined surface applies force, so that the limit adjustment ring 7 uses the vibration force to further slide along the outer side of the elastic positioning plate 6 when vibration occurs, so that the limit adjustment ring 7 will push the slider 14 to slide along the sliding groove of the elastic positioning plate 6, and when the slider 14 slides, it can pull the sealing rubber sheet 15 through the pull rope 16 to slide in the negative pressure groove 301 of the connecting sleeve 3, thereby generating negative pressure between the negative pressure groove 301 and the outer wall of the male seat 1, realizing negative pressure adsorption of the male seat 1 during vibration, and realizing secondary auxiliary locking of the connection between the male seat 1 and the female seat 2, thereby further improving the connection stability of the wiring harness assembly during the bumpy driving of the vehicle, effectively avoiding the phenomenon of vibration disconnection, and ensuring the safety of vehicle driving.
