Abstract

The utility model relates to a safety power plug and socket, comprising a plug and a socket. The safety power plug and socket is characterized in that a control circuit is arranged among copper pieces of the socket and an alternating-current power supply, and is internally provided with a magnetron CK and a relay J1 for switching off/on the copper pieces; and the plug is provided with a magnet CT at the position corresponding to the magnetron C. Compared with the prior art, the safety power plug and socket has the beneficial effects that the performance is stable and reliable; when the socket is not used, the copper piece in jacks are not electrified, and the electric shock can not be caused even though iron nails are inserted; only when the plug matched with the socket is inserted, the magnet triggers the control circuit, the socket can be electrified, so that the electric shock on infants is avoided.

Description

Safety-type power supply plugs and sockets
Technical field
The utility model relates to civil electric appliance socket field, particularly a kind of safety-type power supply plugs and sockets.
Background technology
In life at home, supply socket is one of potential safety hazard in the family, and the electric shock accidents that often has the child to disclose to cause into iron nail and so on conductor takes place, and leads to personal injury accident, makes the head of a family on tenterhooks, and is hard to guard against.Anti-electric shock socket to this situation exploitation is also arranged in the market, and its principle is to adopt a kind of shutoff sheet to get lodged in the jack porch, when inserting a certain jack with iron nail; The shutoff sheet does not move, have only when making two jacks simultaneously stressed with plug, the shutoff sheet just can in turn over; Plug is able to insert, and its weak point is that the resistance of shutoff sheet is very big, the adult was also inserted sometimes do not advanced plug; When electrical appliance power was big, the socket heating made the distortion of shutoff sheet, is prone to cause socket to scrap in addition.
Summary of the invention
The purpose of the utility model provides a kind of safety-type power supply plugs and sockets, and when socket did not use, the copper sheet in the jack was not have electricity; Both made the insertion iron nail also can not cause electric shock; When having only the plug that matches with it to insert, socket just has electricity, avoids child's generation of getting an electric shock.
In order to address the above problem, the utility model adopts following technical scheme:
Safety-type power supply plugs and sockets comprises plug and socket, between the copper sheet of socket and AC power, is provided with control circuit, be provided with in the control circuit make copper sheet disconnected/the magnetron CK and the relay J 1 of energising, corresponding magnetron CK place is provided with magnet CT on the said plug.
Power supply L links to each other with the pin 1 of relay J 1 and an end of capacitor C respectively in the said control circuit; The other end of capacitor C links to each other with the anode of rectifier diode D1; The negative electrode of rectifier diode D1 links to each other with the pin 5 of relay J 1 and the negative electrode of voltage stabilizing didoe D2 respectively; The anode of voltage stabilizing didoe D2 links to each other with the pin 3 of power supply N, relay J 1 and the end of magnetron CK respectively; The other end of magnetron CK links to each other with the pin 6 of relay J 1, and the pin 2 of relay J 1, pin 4 link to each other with copper sheet JP1, copper sheet JP2 respectively.
Be provided with normally opened contact one between the pin 1 of said relay J 1 and the pin 2; Be provided with normally opened contact two between the pin 3 of relay J 1 and the pin 4; Be provided with coil between the pin 5 of relay J 1 and the pin 6.
Compared with prior art, the beneficial effect of the utility model is: stable and reliable for performance, when socket does not use; Copper sheet in the jack is not have electricity; Both made the insertion iron nail also can not cause electric shock, when having only the plug that matches with it to insert, the magnet trigger control circuit; Socket just has electricity, thereby avoids child's generation of getting an electric shock.
Description of drawings
Fig. 1 is the utility model example structure sketch map.
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
See Fig. 1; It is the utility model safety-type power supply plugs and sockets example structure sketch map; Comprise plug and socket; Between the copper sheet of socket and AC power, be provided with control circuit, be provided with in the control circuit make copper sheet disconnected/the magnetron CK and the relay J 1 of energising, corresponding magnetron CK place is provided with magnet CT on the plug.
Power supply L links to each other with the pin 1 of relay J 1 and an end of capacitor C respectively in the control circuit; The other end of capacitor C links to each other with the anode of rectifier diode D1; The negative electrode of rectifier diode D1 links to each other with the pin 5 of relay J 1 and the negative electrode of voltage stabilizing didoe D2 respectively; The anode of voltage stabilizing didoe D2 links to each other with the pin 3 of power supply N, relay J 1 and the end of magnetron CK respectively; The other end of magnetron CK links to each other with the pin 6 of relay J 1, the pin 2 of relay J 1, pin 4 respectively with socket on copper sheet JP1, copper sheet JP2 link to each other.
Be provided with normally opened contact one between the pin 1 of relay J 1 and the pin 2; Be provided with normally opened contact two between the pin 3 of relay J 1 and the pin 4; Be provided with coil between the pin 5 of relay J 1 and the pin 6.
Behind plug insertion socket, magnet CT is near magnetron CK, magnetron CK conducting, and relay J 1 coil gets electric, the pin 1 and pin 2 conductings of relay J 1, the pin 3 and pin 4 conductings of relay J 1, copper sheet JP1 and copper sheet JP2 are connected with the 220V power supply respectively, and plug gets;
Pull up plug, magnetron CK breaks off, and copper sheet JP1 on the socket and copper sheet JP2 dead electricity had both made the insertion iron nail also can not cause electric shock, thereby guaranteed safety.
