Description

Technical Field

[0001] The utility model belongs to the technical field of sockets and relates to an electric shock prevention socket. Background Art

[0002] Sockets are generally installed on walls, floors or terminal boards. Currently, most sockets on the market do not have waterproof functions. Once water enters the socket, a short circuit is likely to occur, causing various accidents, especially in places with high water frequency such as bathrooms and kitchens. For this reason, people have begun to develop waterproof sockets. The most common method is to install a waterproof cover above the socket.

[0003] For example, a utility model patent with application number CN200810196618.4 discloses a waterproof socket with no gap between the waterproof ring and the socket body, and between the waterproof ring and the plug in use, comprising: a socket body, at least one pair of pin holes are provided at the bottom of the inner cavity of the socket body, a placement cavity corresponding to the pin holes is provided at the lower part of the socket body, a plug set is provided in each placement cavity, each plug set is composed of a wiring terminal and a plug set spring, and each plug set spring is located below the corresponding pin hole; a waterproof cover is also hinged on the socket body and matched with the waterproof ring provided at the edge of the inner cavity of the socket body; the waterproof ring is arranged together with the socket body by injection molding to form an integrated structure.

[0004] To sum up, although some existing technical solutions have achieved the goal of preventing electric shock for sockets to a certain extent by improving the waterproofness of sockets, the socket holes are always in a conductive state under normal circumstances. Therefore, users may accidentally reach into the socket holes and get electric shocks. Safety cannot be guaranteed, and there is much room for improvement. Summary of the invention
