Problems solved by technology

This tends to require a high pull-out force when pulling the plug out of the socket; therefore, it makes manual removal of the plug difficult
[0003] Moreover, when pulling out manually, 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, which endangers equipment and personal safety.

Abstract

Provided is a power plug. The power plug comprises a frame body (8) and two plug pins (4), wherein an outer shell (9) is fixed on the frame body (8), and the two plug pins are fixedly connected with the frame body and are bilaterally and symmetrically arranged. The two plug pins (4) are used for being inserted into holes of sockets (3) and are in electrical contact with contacts (31) respectively. The frame body (8) is further internally slidably matched with two symmetrically and bilaterally arranged top open post pieces (7). The structure images of the two top open post pieces (7) are symmetrical, and each top open post piece (7) comprises a top open post foot (72) arranged at the low end position of the top open post piece and used for being connected with the socket (3), a wedge-shaped groove (71) located on an outward side face of the top open post piece (7), an upper stressed convex board (76) located on an inward side face of the top open post piece (7), a lower stressed convex board (75) and a limit end portion (77) located at the upper end position and used for being connected with the outer shell (9).

Description

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