Abstract
The utility model relates to a safety plug and socket. The plug comprises an insulator, wherein one end of the insulator is provided with a metal inserted link, and the other end of the insulator is provided with a power lead; the socket comprises a socket body and plug jacks; the end part of the metal inserted link is provided with metal sheets by extending on the periphery; the plug jack comprises inserted link holes and metal sheet holes communicated with each other; the metal sheet holes are matched with the metal sheets in shape; the inserted link holes are matched with the metal inserted links; the aperture of each inserted link hole is less than that of the cross section of each metal sheet; an inner side in the socket body, opposite to the plug jack, is provided with copper sheets electrically connected with the inserted link; and the other side of each copper sheet props against a spring in the socket body to be positioned. The round metal sheets with the aperture which is greater than that of each inserted link hole are arranged on the plug, and the plug is prevented from falling from the plug jacks due to the fact that the aperture of each metal sheet is greater than each inserted link hole when the plug is inserted in the plug jacks and slips to the inserted link holes, so that the use safety and working efficiency are improved.
Description
(1) technical field
The utility model relates to a kind of safety plug-socket, especially a kind ofly when electrician's instrument mobile operating, can prevent the plugs and sockets that plug comes off.
(2) background technology
The plugs and sockets of selling in the market, the inserted link of plug directly inserts in the jack of socket, and its shortcoming is loose contact; Cause electrical equipment to damage easily, the lost of life, even when 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; Influenced operating efficiency, the influence that brings to operating efficiency that comes off of the electric tool in the mobile operating of high-altitude particularly, its plug is just more obvious.
(3) utility model content
The purpose of the utility model is to solve the deficiency that existing plugs and sockets comes off easily, and a kind of safety plug-socket of plug difficult drop-off is provided.
For this reason, the utility model is taked following technical scheme:
A kind of safety plug-socket, said plug comprise an insulator, and an end of insulator is provided with the metal inserted link, and the other end is a power supply lead wire; Said socket includes socket, jack, and the end of said metal inserted link is extended with sheet metal outside all around;
Said jack includes inserted link hole and the metal film perforation that interconnects, said metal film perforation and sheet metal form fit, and said inserted link hole cooperates with the metal inserted link, and the aperture in said inserted link hole is less than the sheet metal cross section;
In the said socket relatively the jack inboard be provided with the copper sheet that electrically connects with inserted link, the interior spring of said copper sheet opposite side and the socket location that offsets.
The corresponding jack position of said socket is provided with slip and inserts lid.
Said slotting lid free end is provided with protruding handle.
Said sheet metal is rounded.
The utility model has the advantages that: 1, on plug, be provided with the circular metal plate of aperture greater than the inserted link hole; After plug inserts jack and slides onto the inserted link hole; Because the sheet metal aperture greater than the inserted link hole, has avoided plug in jack, to come off, and has improved safety in utilization and operating efficiency; 2, the corresponding jack of socket is provided with the slotting lid of slip, covers jack inserting lid in the time of need not using, and avoids getting an electric shock, and uses safer, reliable; 3, simple in structure, low cost of manufacture, result of use are good.
