[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1

[0030] Reference Figures 1-4 A type of anti-loosening automotive connector, including

[0031] Female connector 1;

[0032] Protective shell 2 is fitted onto the surface of female connector 1;

[0033] Automotive sub-connector 3 is inserted into the interior of female connector 1;

[0034] Circlip 4 is integrally machined onto the surface of automotive sub-joint 3;

[0035] There are two bayonets 5, both of which are located on the surface of the retaining ring 4.

[0036] The snap-fit ​​assembly includes a rotating shaft 10, a transmission rod 11, a hinge rod 12, a slide bar 13, and a hook 14. Each of the transmission rod 11, hinge rod 12, slide bar 13, and hook 14 has two parts. The two ends of the rotating shaft 10 are respectively connected to the top ends of the two transmission rods 11. The bottom end of the transmission rod 11 is hinged to the right end of the hinge rod 12. The left end of the hinge rod 12 is hinged to the right end of the slide bar 13. The left end of the slide bar 13 is hinged to the right end of the hook 14. The hook at the left end of the hook 14 engages with the snap-fit ​​opening 5 of the snap ring 4.

[0037] Adjustment mechanism, which is connected to rotating shaft 10.

[0038] With the above structure: after the user inserts the car sub-connector 3 into the female connector 1, rotate the hooks 14 on both sides so that the hooks 14 are aligned with the slots 5 of the retaining ring 4. Then, by rotating, the hooks 14 can be driven into the slots 5, and the retaining ring 4 can be firmly fixed to the female connector 1 and the protective shell 2.

[0039] Please see Figure 3 The adjustment mechanism includes a handle 6, a lead screw 7, a rack 8, and a gear ring 9. The hole at the top of the handle 6 is inserted into the right end of the lead screw 7. The surface of the lead screw 7 is threadedly connected to the screw hole of the rack 8. The teeth of the rack 8 mesh with the teeth of the gear ring 9. The gear ring 9 is located at the middle of the surface of the rotating shaft 10. When the handle 6 is inserted into the right end of the lead screw 7 and the lead screw 7 is rotated, the lead screw 7 can drive the rack 8 to move to the right using the thread. The rack 8 can drive the gear ring 9 to rotate, and the gear ring 9 can drive the rotating shaft 10 to rotate.

[0040] Please see Figure 3 Limiting teeth are provided on the hole at the top of the handle 6 and the right end of the surface of the lead screw 7. The handle 6 engages with the lead screw 7 through the limiting teeth. The teeth of the handle 6 and the lead screw 7 keep the handle 6 and the lead screw 7 in contact while the handle 6 can also drive the lead screw 7 to rotate.

[0041] Please see Figure 1 Both ends of the lead screw 7 are rotatably sleeved with the right side of the top of the protective shell 2, and the bottom of the rack 8 is slidably connected with the top of the protective shell 2. The lead screw 7 is rotatably set with the protective shell 2 through the bearing to ensure the smooth rotation of the lead screw 7. The rack 8 is slidably set with the protective shell 2 through the slide rail to guide the rack 8.

[0042] Please see Figure 4 A sealing ring 15 is bonded to the left side of the protective shell 2. The sealing ring 15 is located between the protective shell 2 and the retaining ring 4. The sealing ring 15 can seal the gap between the protective shell 2 and the retaining ring 4 to prevent rainwater and other substances from entering the female connector 1 and the automotive female connector 3.

[0043] Please see Figure 1 Both ends of the surface of the rotating shaft 10 are rotatably sleeved with the top of the protective shell 2. The surface of the slide bar 13 is slidably connected with the surface of the protective shell 2. The rotating shaft 10 is rotatably set with the protective shell 2 through the bearing to ensure the smoothness of the rotation of the rotating shaft 10. The slide bar 13 is slidably set with the protective shell 2 through the slide rail to guide the slide bar 13.

[0044] Example 2

[0045] The difference between this embodiment and Embodiment 1 is that the lead screw 7, rack 8, and gear ring 9 are replaced with a worm and a worm wheel meshing on the worm surface. The worm wheel is keyed to the rotating shaft 10. The worm can drive the worm wheel to rotate, and the worm wheel can drive the rotating shaft 10 to rotate. However, the self-locking effect of the worm and worm wheel is far inferior to that of the lead screw 7 and rack 8, and they are prone to loosening. Therefore, the preferred embodiment in this application is the lead screw 7, rack 8, and gear ring 9.

[0046] The female connector 1 and the automotive sub-connector 3 adopt existing technology and can use the connector structure of the patent with application number 202320548661.2.

[0047] The working principle of this utility model is as follows: After the user inserts the car sub-connector 3 into the female connector 1, rotate the hooks 14 on both sides to align the hooks 14 with the slots 5 of the retaining ring 4. Insert the handle 6 into the right end of the lead screw 7 and rotate the lead screw 7. The lead screw 7 can drive the rack 8 to move to the right using the thread. The rack 8 can drive the gear ring 9 to rotate. The gear ring 9 can drive the rotating shaft 10 to rotate. The rotating shaft 10 can drive the transmission rod 11 to rotate to the right. The transmission rod 11 can drive the hinge rod 12 to move to the right. The hinge rod 12 can drive the slide bar 13 to move to the right. The slide bar 13 can drive the hooks 14 to move. The hooks 14 can engage with the slots 5 of the retaining ring 4. Pull the retaining ring 4 to the right to fit tightly against the protective shell 2 and the female connector 1, thus connecting and fixing the female connector 1 and the car sub-connector 3.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
