[0027] Please see Figures 1 to 4 A sealing device for a vehicle headlight wiring harness in this embodiment includes a wiring harness 1, an mounting ring 6 fixedly fitted on the outer peripheral wall of the wiring harness 1, a connecting chamber 2 fitted on the outer peripheral wall of the wiring harness 1, the connecting chamber 2 and the mounting ring 6 fixedly connected, a positioning ring 9 fixedly fitted on the outer peripheral wall of the wiring harness 1, and a sealing component for sealing the connection between the connecting chamber 2 and the positioning ring 9.

[0028] The sealing assembly includes a connecting ring 8, which is fitted onto the outer peripheral wall of the positioning ring 9. A rubber ring 4 is fixedly connected inside the connecting chamber 2. A rubber ring 3 is fixedly fitted onto the outer peripheral wall of the positioning ring 9. The connecting ring 8 passes through the rubber ring 4 and extends into the interior of the connecting chamber 2. A threaded groove 7 is provided on the outer peripheral wall of the mounting ring 6. A threaded hole 5 is provided on the left side of the connecting ring 8. The threaded groove 7 extends into the interior of the threaded hole 5. Two mounting grooves 17 are provided on the right side of the positioning ring 9.

[0029] Among them, the threaded groove 7 and the threaded hole 5 are threadedly connected, the connecting ring 8 and the rubber ring 4 are fitted together, and the rubber ring 4 and the connecting chamber 2 are fixedly connected.

[0030] Specifically, one end of the wire harness 1 passes through the through hole on the housing. By rotating the connecting ring 8, the connecting ring 8 and the mounting ring 6 are connected through the threaded connection between the threaded groove 7 and the threaded hole 5. The connecting ring 8 and the connecting chamber 2 are fitted together, and the rubber ring 3 and the rubber ring 4 are fitted together to seal the connection between the wire harness 1 and the housing.

[0031] Please see Figures 1 to 4 In this embodiment, the positioning ring 9 is provided with a fixing component for fixing the connecting ring 8. The fixing component includes two telescopic rods 15, which are fixedly connected to the inside of two mounting slots 17 respectively. A movable plate 13 is fixedly connected to the side of each telescopic rod 15 near the connecting ring 8. A spring 14 is fitted on the outer peripheral wall of each telescopic rod 15 and fixedly connected to the movable plate 13 and the mounting slot 17 respectively. A positioning rod 11 is fixedly connected to the side of each movable plate 13 near the connecting ring 8. Two positioning holes 10 are opened on the inner peripheral wall of the connecting ring 8. The two positioning rods 11 extend into the inside of the two positioning holes 10 respectively. A pull plate 12 with one end penetrating the mounting slot 17 and extending to the right side of the positioning ring 9 is fixedly connected to the right side of each movable plate 13.

[0032] The positioning rod 11 and the positioning hole 10 are clearance-fitted, the moving plate 13 and the mounting groove 17 are slidably connected, the telescopic rod 15 is composed of a sleeve and a moving rod, one end of the moving rod passes through and extends into the inside of the sleeve, a limiting block located inside the sleeve is fixedly connected to the outside of the moving rod, and a through hole adapted to the moving rod is opened on one side of the sleeve.

[0033] Specifically, pulling the pull plate 12 causes the moving plate 13 to move, which in turn moves the positioning rod 11, compressing the telescopic rod 15 and the spring 14, causing them to retract. The positioning rod 11 and the positioning hole 10 are then aligned on the same center line. Releasing the pull plate 12 allows the positioning rod 11 to reset under the action of the spring 14, inserting it into the positioning hole 10. The gap between the positioning rod 11 and the positioning hole 10 then secures the connecting ring 8.

[0034] Please see Figures 1 to 4 In this embodiment, the positioning ring 9 is provided with a support component for supporting the fixing component. The support component includes two limiting rods 16, which are fixedly connected to the inside of two mounting slots 17. Limiting holes 18 are opened on the opposite sides of the two moving plates 13. The two limiting rods 16 extend into the inside of the two limiting holes 18. Two positioning slots 19 are opened on the left inner wall of the connecting chamber 2. Two rubber blocks 20 are fixedly connected to the left side of the connecting ring 8, with one end extending into the inside of the two positioning slots 19 respectively.

[0035] Among them, the two limiting rods 16 are respectively fitted with the two limiting holes 18 with clearance. The limiting rods 16 are located on the left side of the telescopic rod 15. The connecting ring 8 and the connecting chamber 2 are attached, and the rubber block 20 and the positioning groove 19 are attached.

[0036] Specifically, the moving plate 13 is supported by the clearance fit between the limiting rod 16 and the limiting hole 18, thereby improving the stability of the moving plate 13. The connecting ring 8 and the connecting chamber 2 are fitted together, and the rubber block 20 is inserted into the positioning groove 19 to restrict the connecting ring 8.

[0037] It should be noted that when the connecting ring 8 and the connecting chamber 2 are in contact, the positioning groove 19 corresponds to the rubber block 20, and the positioning rod 11 corresponds to the positioning hole 10.

[0038] The working principle of the above embodiments is as follows:

[0039] One end of the wire harness 1 passes through the through hole on the housing. Pulling the pull plate 12 causes the pull plate 12 to move the moving plate 13. The moving plate 13 moves the positioning rod 11, which compresses the telescopic rod 15 and the spring 14. The connecting ring 8 is rotated, and the connecting ring 8 and the mounting ring 6 are connected through the threaded connection between the threaded groove 7 and the threaded hole 5. The connecting ring 8 and the connecting chamber 2 are in contact. The rubber block 20 is inserted into the interior of the positioning groove 19 to restrict the connecting ring 8. At this time, the positioning rod 11 and the positioning hole 10 are on the same center line. When the pull plate 12 is released, the positioning rod 11 is pushed back to its original position by the action of the spring 14. The positioning rod 11 is inserted into the interior of the positioning hole 10 to fix the connecting ring 8. The rubber ring 3 and the rubber ring 4 are in contact to seal the connection between the wire harness 1 and the housing.
