Abstract

The utility model discloses a plug socket, in particular to an anti-drop plug and socket, wherein the plug is composed of a front shell, a back shell, a connecting bolt, a connecting nut, a plugging sheet and a binding screw; the plugging sheet is provided with an anti-drop convex; the socket is composed of a front shell, a back shell, an on-off switch, an insulator, a plugging sheet clamping body, a biding screw, a wire protecting sheath, a wire clamp board, an insulator fixing screw and a socket insertion body stabilizing spring; the plugging sheet clamping body is provided with an anti-drop concave fit with the anti-drop convex on the plugging sheet. When the plug is inserted into the socket, via the anti-drop convex on the plug and the anti-drop concave on the plugging sheet clamping body of the socket, the convex on the plugging sheet is clamped in the concave on the plugging sheet clamping body of the socket, to prevent drop and realize good contact property.

Description

The Anti-disconnecting plug socket

Technical field

The utility model relates to a kind of plugs and sockets, especially a kind of a kind of Anti-disconnecting plug socket that can prevent that in electrician's instrument mobile operating plug from coming off.

Background technology

The plugs and sockets of Chu Shouing in the market, the inserted sheet of its plugs and sockets and inserted sheet chucking body all are that the plane is to the plane, its shortcoming is in electrician's instrument mobile operating, because the pulling of electric wire, its plug comes off especially easily, causes a lot of unnecessary troubles to work, has influenced operating efficiency, the influence that brings to operating efficiency that comes off of the electrician's instrument in the mobile operating of high-altitude particularly, its plug is just more obvious.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of Anti-disconnecting plug socket.

The technical scheme of the utility model technical solution problem is:

A kind of Anti-disconnecting plug is made up of procapsid, back casing, connecting bolt, attaching nut, inserted sheet, terminal screw, and inserted sheet is provided with the anticreep projection, on overhanging section the side of anticreep projection outside stretching out its housing.

As the anticreep projection on the inserted sheet of the preferred version of the utility model plug on the lateral surface of inserted sheet.

As the utility model plug further the anticreep projection on the inserted sheet of preferred version at the middle part of the medial surface of overhanging section of inserted sheet.

As with the supporting anticreep socket of the utility model Anti-disconnecting plug, forms by procapsid, back casing, on-off switch, insulator, inserted sheet chucking body, terminal screw, wire bushing, card line plate, insulator hold-down screw and the firm spring of socket inserted sheet chucking body, inserted sheet chucking body be provided with described inserted sheet on the anticreep pit that mates of anticreep projection.

Anti-disconnecting plug socket described in the utility model is two-pin plug socket or 3-phase plug socket.

The utility model since plug be provided with the anticreep pit that anticreep projection and supporting with it socket are provided with coupling, again because the effect of the resilience force of socket inserted sheet chucking body, after in plug insertion socket, projection on its inserted sheet just in time is stuck in the pit of socket inserted sheet chucking body, anticreep not only, and contact performance is better.
