A power plug for electrical usage

Abstract

A power plug for electrical usage comprises a frame body (8) fixedly provided with an external housing (9) and two inserted pins (4) fixedly connected to the frame body (8) and arranged bilaterally symmetrically. The two inserted pins (4) are to be inserted to holes of a socket (3) so as to be separately in electrical contact with contacts (31). Two jacking-open column members (7) are arranged symmetrically in the frame body (8) in a sliding and matched mode. The structures of the two jacking-open column members (7) are in mirror symmetry, and each jacking-open column member comprises a jacking-open column foot (72) at the lower end of the jacking-open column member and used for connection with the socket (3), a wedge groove (71) positioned in the side surface, facing towards outside, of the jacking-open column member (7), an upper force bearing protrusive board (76), a lower force bearing protrusive board (75) and a space-limiting end portion (77) at the upper end portion and used for connection with the external housing (9), wherein the upper force bearing protrusive board (76) and lower force bearing protrusive board (75) are positioned on the surface, facing towards the inside, of the jacking-open column member (7).

Description

technical field [0001] The invention relates to the field of plugs for electrical sockets, in particular to a plug 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 for electric power, which can overcome the defects in the prior art. [0005] A plug for electric power according to ...
