Electric-shock-proof power supply device

Abstract

The invention discloses an electric-shock-proof power supply device which comprises a plug part and a socket part arranged at the bottom of the plug part. The plug part comprises a connecting rod, a power connecting piece, and a wire. Each of the two sides of the connecting rod is fixedly provided with an oblique inserting rod extending downward. Slide frames are arranged in the upper end of the socket part in a bilateral symmetry and upward extending manner. The upper end of each slide frame is provided with a limit block. Each slide frame is provided with a downward pressure slot inside. A first pressure spring is arranged on the bottom of each downward pressure slot. A conductive piece is connected in a sliding fit manner between the two downward pressure slots. The upward extending ends of the first pressure springs are fixedly connected with and are in downward pressure fit with the bottom surface of the conductive piece. The socket part is internally provided with inserting holes in positions corresponding to the lower ends of the oblique inserting rods. The socket part is internally provided with left and right slide slots symmetrically arranged between the inserting holes. A baffle fixedly connected with the socket part is arranged between the slide slots. The upper end of each slide slot is provided with a through hole which passes through the top wall of the socket part and is communicated with the area between the slide frames. A conductive pin is arranged in each through hole. The bottom end of each slide slot is provided with a guide slot. The device has a simple structure. The device is powered on automatically once the plug part is plugged into the socket part and powered off automatically once the plug part is pulled off the socket part. The device is of high power supply safety and low use cost.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a power supply device for preventing electric shock. Background technique [0002] As a frequently used electrical equipment, the safety performance of the power supply device is directly related to the personal safety of various groups of people. In daily work and life, we often encounter the need to use the power supply stand to provide power for the power supply head. However, the power supply stand is still energized when it is not in use. Some conductive sheets in the power supply stand are set relatively outside, so that It is easy to cause the danger of electric shock caused by accidental contact of personnel, and there is a great potential safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric shock-proof power supply device, which can solve the above-mentioned problems in the prior...
