A first spring 13 connected to the convex column 11 is arranged on the inner wall of the rotating ring 10, and an auxiliary groove 23 is formed inside the baffle 6.

[0029] A plug - in prevention electrical connector provided by the present utility model includes a socket 1 and a plug 2. A circular ring 3 is arranged on the outer wall of the socket 1, and a plug - in prevention slot 4 is arranged inside the circular ring 3. A plug - in prevention block 5 is arranged on the outer wall of the plug 2, and the plug - in prevention block 5 is inserted into the plug - in prevention slot 4. The plug - in prevention block 5 and the plug - in prevention slot 4 are adapted in specifications. A jack 7 is arranged inside the socket 1, and a baffle 6 is rotatably connected inside the socket 1. A number of through - holes 8 are formed inside the baffle 6, and the diameter of the through - holes 8 is slightly larger than the diameter of the jack 7. A rotating ring 10 is arranged on the outer wall of the baffle 6, and a circular groove 9 is formed inside the socket 1, and the rotating ring 10 is rotatably connected inside the circular groove 9. A convex column 11 is slidably connected inside the rotating ring 10, and a number of fixing grooves 12 are formed inside the circular groove 9. The convex column 11 is snap - fitted into the fixing groove 12.

When the plug - in prevention block 5 and the plug - in prevention slot 4 do not match, the plug 2 cannot be inserted into the socket 1, realizing the function of preventing mis - insertion.

[0030] By setting: Since the plug - in prevention block 5 and the plug - in prevention slot 4 are adapted in specifications, when the plug - in prevention block 5 and the plug - in prevention slot 4 do not match, the plug 2 cannot be inserted into the socket 1, realizing the function of preventing mis - insertion, which can avoid the problem of damage to the conductive rod of the plug 2 caused by mis - insertion. The baffle 6 can rotate inside the socket 1. When the through - holes 8 and the jack 7 do not coincide, the baffle 6 will block outside the jack 7, preventing water and dust from entering the jack 7. The elastic force of the first spring 13 can push the convex column 11 into the fixing groove 12, preventing the baffle 6 from rotating by itself. The auxiliary groove 23 is used to assist in rotating the baffle 6.

[0031] In another embodiment provided by the present utility model, as Figure 1 , 2 and Figure 6 shown, a connecting block 14 is provided on the outer wall of the plug 2, and a through groove 24 is provided inside the ring 3. The connecting block 14 penetrates through the through groove 24. After the connecting block 14 penetrates through the through groove 24, the ring 3 can block the fixing block 16.

[0032] In another embodiment provided by the present utility model, as Figure 6 shown, a sliding plate 15 is slidably connected inside the connecting block 14, and a fixing block 16 is provided on the outer wall of the sliding plate 15. Two elastic springs II 17 are connected to the outer walls of the two sliding plates 15, and the elastic force of the elastic springs II 17 can push the sliding plate 15 and the fixing block 16 to move.

[0033] In another embodiment provided by the present utility model, as Figure 6 shown, the fixing block 16 is blocked on one side of the ring 3, and a movable cavity 22 is provided inside the ring 3. The movable cavity 22 can play a guiding role for the moving block 18.

[0034] In another embodiment provided by the present utility model, as Figure 1 , 2 and Figure 6 shown, a moving block 18 is slidably connected inside the movable cavity 22, and a pushing block 19 is provided on the outer wall of the top of the moving block 18. The pushing block 19 is slidably connected to the outer wall of the ring 3. The moving block 18 and the pushing plate 20 can be pushed through the pushing block 19.

[0035] In another embodiment provided by the present utility model, as Figure 6 shown, a pushing plate 20 is provided on the outer wall of one side of the moving block 18, and an elastic spring III 21 connected to the moving block 18 is provided on the inner wall of the movable cavity 22. The elastic force of the elastic spring III 21 will push the moving block 18 to move.

[0036] In another embodiment provided by the present utility model, as Figure 3 and Figure 6 shown, the pushing plate 20 is located outside the ring 3, and the pushing plate 20 is slidably connected to the outer wall on one side of the ring 3. When the pushing plate 20 moves, it can push the fixing block 16 to move.

[0037] Working principle: Rotate the baffle 6 through the auxiliary groove 23 to align the through hole 8 with the jack 7. After the rotation ends, the elastic force of the first spring 13 will push the convex post 11 to move and be inserted into the inside of the fixing groove 12, which can fix the baffle 6 to prevent the baffle 6 from rotating on its own, so that the anti-misinsertion block 5 is aligned with the anti-misinsertion slot 4. Then insert the plug 2 into the socket 1. Before insertion, the anti-misinsertion block 5 will be inserted into the anti-misinsertion slot 4 first. Because the anti-misinsertion block 5 and the anti-misinsertion slot 4 are set to be adapted in specifications, when the anti-misinsertion block 5 and the anti-misinsertion slot 4 do not match, the plug 2 cannot be inserted into the socket 1, realizing the anti-misinsertion function. As the plug 2 is inserted, the connecting block 14 will penetrate the through groove 24 until the elastic force of the second spring 17 pushes the sliding plate 15 and the fixing block 16 to move, so that the fixing block 16 blocks the rear side of the ring 3, making the connection between the socket 1 and the plug 2 more stable and preventing the socket 1 and the plug 2 from disengaging on their own. When it is necessary to separate the plug 2 from the socket 1, push the push block 19 to drive the moving block 18 and the push plate 20 to move, so that the push plate 20 pushes the fixing block 16 to move, making the fixing block 16 move into the connecting block 14. Pull the plug 2 away from the socket 1 to separate the plug 2 from the socket 1. Then rotate the baffle 6 through the auxiliary groove 23 to make the through hole 8 not coincide with the jack 7. The elastic force of the first spring 13 pushes the convex post 11 to be clamped inside the fixing groove 12. At this time, the baffle 6 will block the outside of the jack 7, which can prevent dust and water from entering the jack 7.

[0038] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
