A power supply device for preventing electric shock

Abstract

The invention discloses an electric shock preventing power supply apparatus. The electric shock preventing power supply apparatus comprises an inserting-connecting part and a socket part arranged at the lower end of the inserting-connecting part; a connecting rod, a power connection sheet and a wire are included in the inserting-connecting part; inclined inserting rods, which are extended downwards, are fixedly arranged on the two sides of the connecting rod respectively; sliding frames are arranged in the upper end of the socket part in a left and right symmetrical and upward extended manner; a limiting block is arranged at the upper end of each sliding frame separately; a lower pressing groove is formed in each sliding frame; a first compression spring is arranged on the bottom surface of each lower pressing groove separately; a conductive sheet is glidingly matched and connected between two lower pressing grooves; the upward extended end of the first compression spring and the bottom surface of the conductive sheet are fixedly connected and are matched in a lower pressing manner; jacks are formed in the corresponding socket part at the lower ends of the inclined inserting rods; sliding grooves which are arranged symmetrically left and right are formed in the socket part among the jacks; a baffle fixedly connected with the socket part is arranged between the sliding grooves; a perforated hole which penetrates through the top wall of the socket part and is connected with the region between the sliding frames is formed in the upper end of each sliding groove; and a conductive pin is arranged in each perforated hole. The electric shock preventing power supply apparatus is simple in structure, can be automatically powered on in inserting and connecting and can be automatically powered off after pulling out, and is relatively high in power supply safety and relatively low in 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...
