Abstract

The utility model relates to a combined structure of a waterproof connector, and the combined structure is used to be fixed on a plate with through holes; the utility model comprises a socket component, a plug component and a waterproof gasket, wherein, the socket component comprises a socket, a screw cap and a waterproof ring. The socket is provided with outer screw thread and a convex ring which is formed at the outer screw thread. The outer screw thread passes through the waterproof ring and a through hole to be connected with the screw thread of the screw cap. The convex ring is formed at the outer side of the plate, and a blocking fixed part is formed on the plate. The plug component comprises a plug and a knob. The plug and the socket are correspondingly inserted and connected. One side of the knob corresponding to the socket is provided with a buckle part which is firmly connected with the blocking fixed part. The waterproof gasket is arranged at the inner side of the convex ring and is clamped between the socket and the plug, so the length of the socket which comes out of the plate can be shortened. In addition, being free from the changes of the thickness of the plate, the socket and the plug can reach good waterproof effect.
