Anti-loosening plug and socket apparatus

Abstract

The invention relates to an anti-loosening plug and socket apparatus. The anti-loosening plug and socket apparatus comprises a plug and a socket; the plug comprises a plug body and a convex sheet; thesocket comprises a rack, a socket shell and a locking mounting column; the convex sheet is arranged on the plug body; the socket shell comprises a socket upper cover and a socket base which are in connection; a through hole is formed in the socket upper cover; a gear and a groove plate are fixed at the two ends of the locking mounting column respectively; spaces for mounting the convex sheet areformed in the groove plate and the locking mounting column; the gear is rotationally fixed on the socket base; rack mounting holes are formed in the two opposite side plates of the socket base respectively; first and second extension ends which slide in the two rack mounting holes are arranged at the two ends of the rack respectively; and the gear is meshed with the rack and the convex sheet is provided with positioning blocks. The anti-loosening plug and socket apparatus is compact in structure and reasonable in design; and by virtue of the gear and rack structure arranged in the socket shell, the gear can be driven by pressing the rack extension ends to enable the positioning blocks in the convex sheet in the plug to be locked in the inner wall of the groove plate and to enable the plugto be fastened on the socket, so that falling off of the plug can be prevented effectively.

Description

technical field [0001] The invention relates to the field of electrical devices, in particular to an anti-loosening plug and socket device. Background technique [0002] Whether it is family life or industrial production, plugs and sockets are indispensable devices. Generally speaking, since household electrical appliances such as televisions, computers, microwave ovens, audio systems, etc., or industrial electrical appliances are frequently used, their plugs are often kept plugged into sockets even if they are not used for a long time . [0003] Although there are various types of switches on the market at present, problems such as aging and loosening of the inserts will inevitably occur with the increase in the life of the socket jack, which will cause the plug to fall off easily, have poor contact or even cannot be inserted. In addition, when the wire connected to the plug is placed on the ground, people may accidentally kick the wire and cause the plug to fall off. The...

Problems solved by technology

[0003] Although there are various types of switches on the market at present, with the increase of the service life of the socket jack, problems such as aging and loose inserts will inevitably occur, which will cause the plug to fall off easily, have poor contact or even cannot be inserted.

In addition, when the wire connected to the plug is placed on the ground, people may accidentally kick the wire and cause the plug to fall off, so a protective design is also required to ensure that the plug is tightly connected to the socket
