Plug device stable in operation

Abstract

The invention provides a plug device stable in operation. The plug device comprises a frame (8) fixedly provided with an outer shell (9) and two bolts (4) which are fixedly connected with the frame (8) and are arranged in a left-right symmetry mode. The two bolts (4) are used for being inserted into holes in a socket (3) so as to make electric contact with contacts (31) respectively. The frame (8) is further provided with two jacking pillar pieces (7) which are arranged in a left-right symmetry mode and slidably matched with each other. The two jacking pillar pieces (7) are structurally in mirror symmetry, each jacking pillar piece (7) comprises a jacking pillar foot (72) located at the lower end and used for being in joint with the socket (3), a wedge-shaped groove (71) formed in the side face, facing outside, of the corresponding jacking pillar piece (7), an upper stressed protruding plate (76) and a lower stressed protruding plate (75) which are located on the side face, facing inside, of the corresponding jacking pillar piece (7) and a limiting end (77) located at the upper end and used for being in joint with the outer shell (9).

Description

technical field [0001] The invention relates to the field of plug devices for electrical sockets, in particular to a plug device with stable operation. 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 device with stable operation, which can overcome the disadvantages of the prior art. [0005] A plug...
