Abstract

The utility model belongs to an improved power plug and a socket. Horizontal inserting sheets are uniformly distributed on the cylindrical surface the plug body of the plug and extend from the cylindrical surface. Elevating blocks controlled by springs are installed in the opening of the center position of the socket corresponding to the horizontal inserting sheets of the plug where contact reeds are symmetrically arranged. The upper parts of the elevating blocks are accordant with the surface of an upper casing of the socket and are movably matched with the opening of the upper casing of the socket. The flange of the lower part of each elevating block is matched with the border of a through hole on a partition board of the socket. The horizontal bell crank space of each horizontal contact reed in the shape of a bell crank coincides with each horizontal inserting sheet of the plug. The utility model has safe and reliable use, and firm contact, and the accidents of poor contact, falling off and electric shock can not occur.

Description

Improved attaching plug and socket

The utility model relates to a kind of attaching plug and socket, particularly improved attaching plug and socket.

Attaching plug that uses on the existing power consumption equipment and socket are that the inserted sheet of plug directly inserts in the jack of socket.Its weak point is that the inserted sheet of plug does not also insert in the socket fully or when also from socket plug not extracted fully, exposed metal insert outside is charged, when misoperation, the accidental contact of human body can take place also, electric shock accidents occurs.In addition, service time is when longer, and the contact spring in the socket loses elastic force, can produce plug and socket loose contact or use midway that plug comes off.

The purpose of this utility model is to provide a kind of improved attaching plug and socket, it is safe and reliable, and when beginning to pull the plug out of the socket in socket, metal insert is outage fully, when occurring misoperation exactly or accidental contact situation occurring, electric shock accidents can not appear yet.In addition, the inserted sheet of plug contacts firmly reliable with the metal spring leaf of plug, can not come in contact phenomenon bad or that come off.

The utility model is achieved in that a kind of improved attaching plug and socket, comprise attaching plug and socket, uniformly on the plug body face of cylinder of plug stretching out horizontal inserted sheet, the horizontal inserted sheet of corresponding plug is being symmetrical arranged contact spring in the socket upper shell, in the perforate in the centre in the socket spring controlled elevator is installed, elevator top is concordant with socket upper shell surface, and with the perforate of socket upper shell movingly, the rib of its underpart matches with the through hole limit on the socket dividing plate, contact spring leaf be shaped as horizontal crank throw shape, the horizontal crank throw space of scratching on it and the horizontal inserted sheet of plug match.

When the utility model uses, with the elevator on the plug alignment socket, plug and elevator are pressed in the socket rotary connector together, the horizontal crank throw space of scratching on the contact spring of corresponding horizontal crank throw shape in the horizontal inserted sheet of plug and the socket is matched, then power connection; When needing outage, the reverse rotation plug is thrown off the metal insert of plug and the contact spring in the socket, though this moment, plug was not extracted socket, cuts off the power supply, pulls the plug out of the socket, and elevator is return under the effect of spring.The utility model is safe and reliable, does not exist charged metal insert to expose in the socket outside, and therefore any situation electric shock accidents can not take place.Because metal insert relies on the thrust of spring contact with the socket contact spring, contacts reliably, the phenomenon that does not have loose contact or use plug midway to come off.

Below in conjunction with accompanying drawing the utility model is further described, a kind of improved attaching plug and socket comprise attaching plug and socket, uniformly on the plug body face of cylinder of plug 1 are stretching out horizontal inserted sheet 2; The horizontal inserted sheet 2 of corresponding plug 1 is symmetrical arranged contact spring 4 in socket 3 upper shells, the elevator 5 of spring 6 controls is installed in the perforate in the centre in the socket 3, elevator 5 tops are concordant with socket 3 upper shell surfaces, and with the perforate of socket 3 upper shells movingly, the rib of its underpart matches with the through hole limit on socket 3 dividing plates 8, contact spring leaf 4 be shaped as horizontal crank throw shape, the horizontal crank throw space of scratching on it and the horizontal inserted sheet 2 of plug 1 match, the quantity of the horizontal inserted sheet 2 of plug 1 is 2-4, the quantity of the contact spring leaf 4 in the socket 3 is corresponding with the quantity of the horizontal inserted sheet 2 of plug 1, perforate periphery at socket 3 upper casings is being provided with the safe edge 7 that extends downwards, the height of safe edge 7 is to be advisable near spring reed 4, preventing that finger from stretching into touches spring reed 4 and gets an electric shock in the perforate, safe edge 4 plays the security protection effect.
