In this embodiment, a third protruding point is convexly disposed on the inner periphery of the second gasket 390, a third interference groove 311a corresponding to the third protruding point is disposed on the outer periphery of the second mounting flange 311, and the third protruding point is located in the second interference groove, so that the second gasket 390 and the second mounting flange 311 are positioned in an interference manner. A fourth convex point is convexly arranged on the outer peripheral edge of the second gasket 390, a fourth interference groove corresponding to the fourth convex point is formed in the second mounting flange portion 3125, and the fourth convex point is located in the fourth interference groove, so that the second gasket 390 and the second mounting flange portion 3125 are relatively interfered and positioned, and in addition, the second gasket 390 and the second mounting flange 311 are relatively interfered and positioned, so that the second gasket 390 is more reliably positioned. The second gasket has the same structure as the first gasket. The structure of the second mounting flange portion is the same as that of the first mounting flange portion.

because the plug body 110 is provided with the insertion groove 112 and the open groove 114 which are communicated, the insertion groove 112 is connected with the socket connector 300 in an insertion and extraction manner, when sundries or water fall into the insertion groove 112, the sundries or water can be discharged through the open groove 114, or a user can clean the sundries or water through the open groove 114, so that the problem that the sundries or water in the slot is difficult to clean by the user is solved; even if the user does not notice the sundries or water and does not perform the cleaning operation, the sundries or water are extruded by the insertion of the socket connector 300 and discharged into the open slot 114 during the process of inserting and pulling the inserting slot 112 into and out of the socket connector 300, thereby solving the problem of short service life of the equipment.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention.
