A safe power supply device

Abstract

The invention discloses a high-power electric power supply device. The device comprises a plug and a socket; the plug comprises an insulator, insertion pins and wires; the socket comprises a socket body and elastic sheets; the socket further comprises a socket core; a guide hole is formed in the socket; the socket core is arranged in the guide hole; the opening of the guide hole is provided with acover plate; insertion holes which are shaped to match the insulator are formed in the cover plate and the socket core; elastic grooves b are formed in the side surface of the socket core; elastic grooves a are formed in the inner wall of the guide hole; elastic units b are arranged in the elastic grooves b; springs and elastic units b are arranged in the elastic grooves a; the springs are arranged at the bottoms of the elastic grooves a; when the socket core is attached to the cover plate, the elastic grooves b are aligned with the elastic grooves a; grooves are formed in the surface of theinsulator; when the insulator is inserted into the bottom of the insertion hole of the socket core, the elastic units a are in the grooves of the insulator, the elastic units a are all in the elasticgrooves b; and the elastic units b are all arranged in the elastic grooves a. The electric power supply device is unlikely to be loosened; the insertion pins of the electric power supply device have little possibility of being damaged; and erroneous insertion connection can be prevented.

Description

technical field [0001] The invention relates to the technical field of electric power supply equipment, in particular to an electric power supply device with high safety. Background technique [0002] In the field of electric power supply, the plug-in device is one of the indispensable accessories of electric equipment, but the pins of the existing plug-in plug are exposed, easily damaged and deformed, resulting in poor contact, and it is difficult to ensure the stability of the electrical connection ;The existing structure is not safe enough for some people with low safety awareness and low cognitive ability, such as children, because they are more curious, exploring, and playful, and it is impossible for parents to watch their children all the time, so , When the parents are not paying attention, they will use metal rods, keys and the like to insert into the jack, and such behavior will cause electric shock accidents, which will cause great harm to the human body and cause...

[0002] In the field of electric power supply, the plug-in device is one of the indispensable accessories of electric equipment, but the pins of the existing plug-in plug are exposed, easily damaged and deformed, resulting in poor contact, and it is difficult to ensure the stability of the electrical connection ;The existing structure is not safe enough for some people with low safety awareness and low cognitive ability, such as children, because they are more curious, exploring, and playful, and it is impossible for parents to watch their children all the time, so , When the parents are not paying attention, they will use metal rods, keys and the like to insert into the jack, and such behavior will cause electric shock accidents, which will cause great harm to the human body and cause death in severe cases. The traditional There is a great potential safety hazard in the plug-in device; the plug has poor stability during use and is easily loosened by dragging and pulling, resulting in poor circuit contact and affecting the normal use of electrical equipment
