Abstract

The utility model belongs to an improved power safety plug and a socket. Circular arc metal plates from which radial bending parts in the shape of a circular arc extend are uniformly distributed on the cylinder surface of the plug body of the plug. Radial contact reeds in the shape of a circular arc which are contacted and matched with metal inserting plates and are responding to the metal inserting plates are installed in the socket. An elevating block controlled by springs is installed in the opening of the center position, and the contact reeds are symmetrically installed on the center position in the socket. The upper part of the block is accordant with the surface of an upper casing of the socket and is movably matched with an opening of the upper casing of the socket. A flange on the lower part of the block is matched with the border of a through hole on a partition board of the socket. The utility model is safe and reliable in use. The contact is firm and the accidents of poor contact, falling off and electric shock can not occur.

Description

Improved Power supply safety plug and socket

The utility model relates to a kind of attaching plug and socket, particularly improved Power supply safety 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 Power supply safety 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 Power supply safety plug and socket, comprise attaching plug and socket, the uniform circular arc sheet metal that stretches out on the plug body face of cylinder of plug with the bending of circular radial arcuation, be installed with in the socket and the corresponding circular radial arcuation of metal insert contact matching contact spring, in the perforate in the centre of 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.

When the utility model uses, with the elevator on the plug alignment socket, plug and elevator are pressed in the socket together, rotary connector matches the radially circular arc sheet metal of plug and the contact spring of the interior corresponding circular radial arcuation of socket, then power connection; When needing outage, the reverse rotation plug is thrown off the metal insert of plug and the contact spring of 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 outside at socket, therefore electric shock accidents can not take place in any case.Because the arc surface of metal insert rotation back contact with the arc surface of 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 Power supply safety plug and socket, comprise attaching plug and socket, the uniform circular arc sheet metal 2 that stretches out on the plug body face of cylinder of plug 1 with the bending of circular radial arcuation, be installed with in the socket 3 and the corresponding circular radial arcuation of metal insert 2 contact matching contact spring 4, the elevator 6 of spring 7 controls is installed in the perforate in the centre of socket 3, elevator 6 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 the socket dividing plate 8.The quantity of plug 1 circular arc metal insert 2 is 2-4, the quantity of the contact spring 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 5 that extends downwards, the height of safe edge 5 is to be advisable near contact spring 4, preventing that finger from stretching into touches contact spring 4 and gets an electric shock in the perforate, safe edge 5 plays the security protection effect.
