Plug assembly for electric power

Abstract

The invention relates to a plug assembly for electric power. The plug assembly comprises a frame body (8) which is fixedly provided with an external shell (9), and two bolts (4) which are fixedly connected with the frame body (8) and arranged bilaterally symmetrically to each other, wherein the two bolts (4) are inserted into the holes of a socket (3) to be respectively electrically contacted with a contact (31); two ejector rods (7) which are bilaterally symmetrically arranged are fit in the frame body (8) in a sliding manner; and the structures of the two ejector rods (7) are mirror symmetrical, and each ejector rod (7) includes an ejector rod base (72) positioned at the lower end and used for being connected with the socket (3), a wedge-shaped groove (71) formed in the side surface, facing outwards, of the ejector rod (7), an upper stress convex plate (76) and a lower stress convex plate (75) positioned on the side surface, facing inwards, of the ejector rod (7) and a limit end part (77) positioned at the upper end and used for being connected with the external shell (9).

Description

technical field [0001] The invention relates to the field of plugs for electrical sockets, in particular to a plug assembly for electric power. Background technique [0002] When the pin of the plug is in contact with the hole of the socket, in order to ensure good electrical contact and have a stable holding force, the joint between the pin and the contact usually has a strong engagement force or friction force. This tends to require a greater pull-out force when pulling the plug out of the socket; thus, it makes manual pull-out of the plug difficult. [0003] Moreover, when manually pulling out, due to the instability of the force, it is easy to cause sparks with the electrical contacts during the process of pulling out the plug, endangering equipment and personal safety. Contents of the invention [0004] The object of the present invention is to provide a plug assembly for electric power, which can overcome the defects in the prior art. [0005] A plug assembly for e...
