Safety plug device for power supply

Abstract

The invention discloses a safety plug device for power supply, and the device comprises a socket body which is fixedly installed in a wall body, and a plug body which is connected with power equipment through a wire. The socket body is provided with slots in a manner of lateral symmetry, and the outer side end walls of the slots are provided with power supply grooves. The front end walls of the power supply grooves are provided with power supply elastic pieces. The front end face of the socket body is provided with locking stretch-in grooves in a manner of lateral symmetry, and the rear ends of the locking stretch-in grooves are provided with locking grooves which extend towards outer side ends. The rear end face of the plug body is provided with power supply pins in a manner of lateral symmetry, and each power supply pin comprises a lead-in block cooperating with the corresponding slot, and a plug bar which is fixedly disposed on the rear end face of the plug body. Each lead-in block is provided with a longitudinal groove and a lateral groove, wherein the opening of the longitudinal groove faces forwards, and the opening of the lateral groove faces an outer side end. The lateral grooves are communicated with the longitudinal grooves. The plug bars stretch into the longitudinal grooves, and the lateral grooves are slidingly provided with telescoping arms. The inner side end of each telescoping arm is provided with an extruding inclined surface and a jacking surface, wherein each extruding inclined surface stretches out of the corresponding lateral groove, and stretches into the corresponding longitudinal groove to abut against an extruding action surface of the rear end of the plug bar.

Description

technical field [0001] The invention relates to the field of electric power supply, in particular to a safety plug-in device for power supply. Background technique [0002] Generally, electrical equipment needs to be powered on before it can work, and the electrical equipment is powered by the cooperation of the plug body and the socket body. The traditional plug and socket use the friction between the two to achieve The state is locked when it is inserted, but this locking method is extremely unstable. When the plug body is accidentally touched or lifted, it is easy to separate or loosen the plug body and the socket body. The equipment is prone to failure, and in the traditional socket, the electric equipment can be powered when the conductive column of the plug is inserted into the socket, but this structure is not safe enough, for example, in the household socket, some young children who lack safety awareness For children, things such as iron rods and keys can be inserte...

[0002] Generally, electrical equipment needs to be powered on before it can work, and the electrical equipment is powered by the cooperation of the plug body and the socket body. The traditional plug and socket use the friction between the two to achieve The state is locked when it is inserted, but this locking method is extremely unstable. When the plug body is accidentally touched or lifted, it is easy to separate or loosen the plug body and the socket body. The equipment is prone to failure, and in the traditional socket, the conductive column of the plug can be inserted into the socket to supply power to the electrical equipment, but this structure is not safe enough, for example, in household sockets, some young children who lack safety awareness For children, things like iron rods and keys will be inserted into the jack, which will cause casualties to children, and such reports often appear. Therefore, there are great potential safety hazards in traditional power supply sockets
