Abstract
The utility model relates to a power-supply safety socket. The socket is composed of an existing bottom plate, the copper sheet of a conduct electrode, screws and a face cover. A safety protective valve composed of a valve plate, a spring, a rotation shaft and the support base of the rotation shaft is added in a plug hole on the face cover of the socket. The valve plate rotates around the rotation shaft. The spring is sheathed on the rotation shaft. The support base of the rotation shaft is connected with the face cover in a whole. The plug hole can be sealed through the valve plate. The valve plate is in the state of sealing the plug hole due to spring force. The copper sheet of a conduct electrode on the socket is completely insulated from the outside. When the plug is inserted into the socket, the valve plate is in the state of forced opening. The copper pole (sheet) of a conduct electrode of the plug is contacted with the copper sheet of a conduct electrode of the socket for switching on a power supply. When the plug is pulled out, the state that the plug hole is sealed by the valve plate is restored by means of the spring force.
Description
The utility model be a kind of supply voltage at the appliances power source socket below 500 volts, no matter whether appliance plug insert socket, charged socket is in a safe condition all the time.
At present, known supply socket is: the conductive electrode copper sheet by screw on base plate, be screwed power lead-ining line on the base plate, cover by screw on base plate, cover is provided with plug hole, the plug hole position is corresponding with conductive electrode copper sheet on the base plate, and the conductive electrode copper sheet contacts energized on the copper post (sheet) that relies on conductive electrode on the plug and the socket, and base plate and cover are insulating material.When not plug-in device plug, the conductive electrode copper sheet is by plug hole on the cover on the charged socket, be actually exposed, especially Modern Family, public place and workshop, various electrical equipment are more, the quantity that socket uses is also a lot, and most socket position settings are very low, also some is mobile character, to the movable frequent place of people, especially child, make the people feel there is not the sense of security, in fact, also easily make the people directly or by conductor touch charged copper sheet in the plug hole indirectly, the generation of the phenomenon that causes getting an electric shock.
Whether the purpose of this utility model is: a kind of appliances power source safety socket is provided, and it not only has the function of present common socket, and no matter insert under the socket situation at appliance plug, and charged socket is in a safe condition all the time.
The purpose of this utility model be achieved in that the conductive electrode copper sheet by screw on base plate, base plate is provided with the power lead-ining line hole, be screwed power lead-ining line on the base plate, cover by screw on base plate, cover is provided with plug hole, the plug hole position is corresponding with base plate conductive electrode copper sheet, plug hole is established one or more groups, establish two holes or three holes for every group, every group is used for plug, and each plug hole position is provided with safety protective valve on cover, and safety protective valve is by valve plate, spring, rotating shaft and shaft seating are formed, base plate, cover, valve plate is insulating material, valve plate is provided with the rotating shaft duct, and valve plate can rotate around the axis, and shaft seating is inserted in rotating shaft, shaft seating and cover fuse, spring housing in rotating shaft, spring one end bearing on cover or the shaft seating, the other end is pressed on the valve plate, the valve plate size is of a size of suitablely can sealing surface to cover plug hole, and the elastic force of spring should make valve plate be in normally closed (plug hole is sealed by valve plate) state; But the elastic force of spring can not stop the adult to impose on makes plug conducting utmost point copper post (sheet) enter plug hole on the plug, force valve plate to be in the force open state: under the force open state, if pull the plug out of the socket, conductive electrode copper post (sheet) leaves plug hole on the plug, valve plate relies on the elastic force of spring to recover normally off voluntarily, when reaching charged socket and not inserting plug, the plug mouth is in the safe condition of insulation sealing.
Owing to adopt such scheme, can make the appliances power source socket, not only have the function of present common socket, face and not inserting under the appliance plug situation, the conductive electrode copper sheet is in insulation sealing guard mode on the charged socket, and is as safe as a house, simple in structure.
Accompanying drawing (the one group of socket in two holes) below in conjunction with embodiment further specifies the utility model:
Fig. 1 is the plane graph of the utility model embodiment socket base plate.
Fig. 2 is the plane graph of the utility model embodiment socket cover.
Fig. 3 is the figure that faces upward of the utility model embodiment socket base plate.
Fig. 4 is the I-I profile of the utility model embodiment.
Fig. 5 is the II-II profile of the utility model embodiment.
Fig. 6 is spring two views of safety protective valve on the utility model embodiment.
Among the figure: 1; conductive electrode copper sheet 2 on the socket base plate; socket base plate power on source lead-in terminal screw and copper sheet 3; screw on the fixed socket base plate and screw hole 4; socket power lead-in hole 5; screw that the fixed socket cover is used and screw hole 6; socket cover plug hole place is provided with the valve plate 7 of safety protective valve; spring 8 on the safety protective valve; rotating shaft 9 on the safety protective valve; shaft seating 10 on the safety protective valve; the screw 11 of conductive electrode copper sheet on the fixed socket base plate; plug hole on the cover
In the figure of the utility model embodiment, valve plate 68 rotates and is subjected to spring 7 elastic force effects to force valve plate 6 sealing plug holes 11, conductive electrode copper sheet 1 and external insulation in the socket around the shaft; When plug firmly makes plug conducting utmost point copper post (sheet) when stretching into socket aperture, valve plate 6 is forced to 8 rotate around the shaft, on the plug conductive electrode copper post (sheet) enter in the socket with socket on conductive electrode copper sheet 1 contact energized; When pulling the plug out of the socket, valve plate 6 is subjected to the elastic force effect of spring 7, returns to sealing plug hole state.Valve plate 6 sizes are advisable can seal plug hole 11, valve plate 6 is provided with the duct for wearing rotating shaft 8 usefulness, bearing 9 fuses with cover, valve plate 6 and spring 7 are enclosed within the rotating shaft 8, and rotating shaft 8 is inserted on the shaft seating 9, and an end bearing of spring 7 is on cover, the other end of spring 7 is pressed on the valve plate 6, the shape of copper sheet 1, size are advisable with reliable contact of copper sheet 1 with plug conducting utmost point copper post (sheet) not influence valve plate 6 rotations, and valve plate 6 material therefors are electrical insulating material with socket base plate and cover.
