The first rubber sealing ring 24 and the second rubber sealing ring 25 are used to abut against each other after the plug 11 and the socket 1 are inserted together, thereby further enhancing the sealing performance of the connector and forming a second waterproof and dustproof barrier to prevent moisture and dust from entering the connector and affecting its use. A protruding ring 21 is fixedly connected to the inner surface of the mounting ring 2. The surface of the second rubber sealing ring 25 is connected to a rubber sealing ring 22. The rubber sealing ring 22 is used to tightly wrap the cable 12 passing through it, forming the first waterproof and dustproof barrier, thereby enhancing the sealing performance of the connector and preventing moisture and dust from entering the connector and affecting its use. The surface of the rubber sealing ring 22 has a groove 23, and the protruding ring 21 is inserted into the groove 23, thereby installing the rubber sealing ring 22 on the mounting ring 2 and enhancing the sealing effect. The surface of the second rubber sealing ring 25 is fixedly connected to a third rubber sealing ring 26, which is used to insert into the first rubber sealing ring 24, thereby improving the sealing effect of the first rubber sealing ring 24 and the second rubber sealing ring 25.

[0028] Furthermore, the guiding mechanism includes a fixing block 3 and a fixing plate 32. The fixing block 3 is fixedly connected to the surface of the socket 1, and the fixing plate 32 is fixedly connected to the surface of the plug 11. The fixing plate 32 is used to fix the guide rod 33 to the plug 11. The surface of the fixing block 3 is provided with a guide groove 31. The fixing block 3 and the guide groove 31 are used to cooperate with the guide rod 33 to achieve the guiding function, ensuring that the socket 1 and the plug 11 are accurately aligned during the insertion process, thereby avoiding the first rubber sealing ring 24 and the second rubber sealing ring 25 from being misaligned and thus reducing the sealing effect. The surface of the fixing plate 32 is fixedly connected with the guide rod 33, which is used to cooperate with the guide groove 31 to achieve the guiding function, ensuring that the socket 1 and the plug 11 are accurately aligned during the insertion process, thereby avoiding the first rubber sealing ring 24 and the second rubber sealing ring 25 from being misaligned and thus reducing the sealing effect.

[0029] Furthermore, the mounting ring 2 is circular in shape and is used to mount the rubber sealing ring 22 onto the plug 11. The convex ring 21 can fit perfectly into the slot 23.

[0030] Furthermore, the rubber sealing ring 22 can slide on the surface of the cable 12. The rubber sealing ring 22 is used to tightly wrap the cable 12 passing through it, forming the first waterproof and dustproof barrier, thereby enhancing the sealing performance of the connector and preventing moisture and dust from entering the connector and affecting its use. The convex ring 21 is inserted into the slot 23, thereby installing the rubber sealing ring 22 on the mounting ring 2, which can also enhance the sealing effect. The second rubber sealing ring 25 is circular. The first rubber sealing ring 24 and the second rubber sealing ring 25 are used to abut against each other after the plug 11 and the socket 1 are plugged together, thereby further enhancing the sealing performance of the connector and forming the second waterproof and dustproof barrier, preventing moisture and dust from entering the connector and affecting its use.

[0031] Furthermore, the third rubber sealing ring 26 can be fitted into the first rubber sealing ring 24. The third rubber sealing ring 26 is annular and is used to insert into the first rubber sealing ring 24, thereby improving the sealing effect of the first rubber sealing ring 24 and the second rubber sealing ring 25.

[0032] Furthermore, the fixing blocks 3 are symmetrically distributed in two sets on the surface of the socket 1, and the guide groove 31 is circular. The fixing blocks 3 and the guide groove 31 are used to cooperate with the guide rod 33 to achieve the guiding function, ensuring that the socket 1 and the plug 11 are accurately aligned during the insertion process, thereby avoiding the misalignment of the first rubber sealing ring 24 and the second rubber sealing ring 25, which would reduce the sealing effect.

[0033] Furthermore, the fixing plates 32 are symmetrically distributed in two sets on the surface of the plug 11. The fixing plates 32 are used to fix the guide rod 33 on the plug 11. The guide rod 33 is round and is used to cooperate with the guide groove 31 to achieve the guiding function, ensuring that the socket 1 and the plug 11 are accurately aligned during the insertion process, thereby avoiding the misalignment of the first rubber sealing ring 24 and the second rubber sealing ring 25, which would reduce the sealing effect.

[0034] Working principle: Pushing the rubber sealing ring 22 causes it to fit into the mounting ring 2, and the convex ring 21 will engage with the slot 23, thus installing the rubber sealing ring 22 on the mounting ring 2. The rubber sealing ring 22 can tightly wrap around the cable 12 passing through it, forming the first waterproof and dustproof barrier, thereby enhancing the sealing performance of the connector and preventing moisture and dust from entering the connector and affecting its use. At the same time, after the plug 11 and the socket 1 are plugged together, the first rubber sealing ring 24 and the second rubber sealing ring 25 will abut against each other, and the third rubber sealing ring 26 will insert into the first rubber sealing ring 24, thereby further enhancing the sealing performance of the connector and forming the second waterproof and dustproof barrier, preventing moisture and dust from entering the connector and affecting its use.

[0035] The guide groove 31 and guide rod 33 can ensure that the socket 1 and plug 11 are accurately aligned during the insertion process, thereby avoiding misalignment of the first rubber sealing ring 24 and the second rubber sealing ring 25, which would reduce the sealing effect.
