Self-locking plug adapter

Abstract

The invention discloses a self-locking plug, which comprises an outer casing, a plug wafer, a self-locking elastic element and a pressing handle; the self-locking elastic element comprises a self-locking part, a positioning part and a stress deformed part which extend out the outer casing; the self-locking part is provided with the plug wafer side by side, one end away from the outer casing bendstowards the direction at the inner side of the plug wafer, and the basic configuration of the stress deformed part adopts a camber line shape; each pressing handle comprises a pressing part and a roof pressing part, the pressing part extends out the outer casing, and the pressing handle is held against on the stress deformed part of the self-locking elastic part. The invention has the advantages that the structure is simpler, the operation is convenient, and the self locking effect is better.

Description

self-locking plug technical field The invention belongs to the technical field of electric accessories, and in particular relates to a self-locking power plug. Background technique The traditional power plug does not have a self-locking function. After plugging, it is combined by the friction between the plug contact piece and the elastic piece in the socket. The connection of the plug and socket is loose and the connection is not strong, and the stability is poor when contacting. The plug will be separated from the socket if it is slightly pulled by an external force. Chinese patent 87202131 discloses a self-locking plug and socket for electrical power supply. There is a rotator made of insulating material on the socket, and the socket is fixed on it. Self-locking device, after the plug is inserted, open the self-locking device on the rotator, and then rotate a certain angle together with the rotator, so that the socket contact piece on the rotator contacts the electric...

AI Technical Summary

Problems solved by technology

The disadvantages of this self-locking plug and socket are: (1) There are too many components, the structure is relatively complicated, and the processing is inconvenient. Compared with the traditional plug, the cost increase is too high

(2) The self-locking plug and the socket are locked, and it can only be pulled out after rotating it at a certain angle. In addition, the shape of the self-locking plug is similar to that of the traditional plug, which often occurs to users. Accidents that mistook it for a traditional plug and directly pulled out the plug by force according to the traditional method, so that the plug was damaged
