Description

A kind of the two poles of the earth electrical socket

The utility model relates to electrical socket, particularly a kind of the two poles of the earth electrical socket.

Sold the two poles of the earth electrical socket that a kind of panel that comprises pedestal, shutter, back-moving spring and the band twin jack of being with sleeve component is formed in the city.This electrical socket is at ordinary times owing to two jacks that have shutter to seal on the panel have safety protection function.During work; the two poles of the earth plug touches shutter; make the back-moving spring pressurized; shutter retreats; the two poles of the earth plug could two jacks on panel enters the sleeve component in the pedestal; thereby finish normal electrical connection, but the two poles of the earth electrical socket of above-mentioned structure can not stop too one pole latch or single foreign matter to insert.When using the electrical socket of above-mentioned structure in the family; child does not note because of curiosity or adult; when having one pole latch or single foreign matter to insert in the electrical socket of described the two poles of the earth, just might cause the generation of electric shock accidents, therefore the safety protection function of the electrical socket of above-mentioned structure when work is incomplete.

The purpose of this utility model is that a kind of improved the two poles of the earth electrical socket will be provided.Two jacks on this socket panel are closed at ordinary times; During work, socket only allows the two poles of the earth plug to insert, do not allow one pole latch or single foreign matter to insert.

Task of the present utility model is finished as follows.

A kind of the two poles of the earth electrical socket; pedestal with band sleeve component; the panel of band groove, slide rail, jack; being provided with in the described groove can be along the shutter of slide rail slip; be embedded with back-moving spring between described shutter and the groove frame; its characteristics are to be respectively equipped with shape about described shutter end face and jack is complementary, position and the corresponding projection of jack; the height of described projection and shutter thickness sum are slightly less than the height of groove frame, and described shutter middle part is provided with the chute that guarantees that shutter can slide again and can stir around slide rail along slide rail.

Can be respectively equipped with 1/2 part or its line part of shape and jack about shutter end face of the present utility model or its curved portion is complementary, position and the corresponding projection of jack.

To exceed the altitude range of shutter end face can be the 0.5-1.0 millimeter to two projectioies on the utility model shutter.

The cross section of shutter of the present utility model middle part chute can be up big and down small trapezoidal, and described trapezoidal width of going to the bottom and slide rail width are complementary.

The utility model is owing to adopted the shutter of band projection and chute structure, therefore shutter can be sealed jack on the panel under the effect of back-moving spring at ordinary times, during work, the two poles of the earth plug can be pushed shutter open along slide rail, and latch enters pedestal by jack and realizes being electrically connected with sleeve component; When one pole latch or single foreign matter enter jack; shutter is stirred around slide rail, and the projection of shutter perk one end is embedded in the corresponding jack, shutter can not be slided along slide rail; shutter still is in the position of closure panel jack, thereby plays the safeguard protection effect.Compared to the prior art, the safeguard protection the during work of the utility model the two poles of the earth electrical socket is complete, the reliability height.Through test, the utility model product meets the GB2099.1-1996 family expenses and the similar applications plugs and sockets first of soon playing enforcement on February 1st, 97 fully; General requirement, i.e. " with a latch of the plug of same system towards the direction perpendicular to the socket front surface, the power that applies 40N (newton) to the shutter of a jack reaches 1min (branch), and shutter does not damage ".Described test shows: this normal pressure be increased to 75N energetically the time, shutter does not damage yet.Under normal charged situation, do to insert life test and do not damage for 6000 times, surpass 5000 standards of national regulation.Therefore the utility model the two poles of the earth electrical socket all meets national standard in increased force will and two tests of operate as normal.

Below with reference to accompanying drawing structure of the present utility model is described in further detail.
