Abstract

The utility model relates to a waterproof socket comprising a socket body. At least one set of jacks are arranged in the socket body. A conductive assembly in electric connection with the jacks is arranged inside the socket body. The conductive assembly is connected with an external power line through a conductive wire. The socket body is provided with a via hole for the above conductive wire to go through. The waterproof socket is characterized in that a wire protective sleeve which sleeves the conductive wire is arranged between the via hole and the conductive wire in a clamped mode; a cone-shaped protective ring is arranged inside the wire protective sleeve; and a minor-caliber portion of the cone-shaped protective ring is arranged in a mode of facing towards a socket. The arrangement of the cone-shaped protective ring has an effect of blocking water entering the wire protective sleeve to prevent the water from further filtering into the socket, so that the sealing performance of the connection portion between the conductive wire and the socket is raised, and the socket is enabled to have a better waterproof effect.
