Abstract
The utility model discloses a power-off protection socket. The socket includes a casing which comprises a rear cover and a front cover and a PCB which is arranged in the casing. A power supply and socket electrical brushes are arranged on the PCB. Electrical brush insert holes are arranged on positions of the front cover, corresponding to the socket electrical brushes. Improvements are that a normally-open-contact relay and a power button are also arranged on the PCB. In the power-off protection socket, the relay and the power button are arranged on the PCB so that when the socket is powered off, the power supply can be disconnected automatically. When power is supplied again, the socket electrical brushes on the socket can be powered on only after the power button is pressed manually by a person. Therefore, it is prevented that electrical appliances are damaged or even burned or a fire is caused because of a sudden power-on or voltage surge so that the socket plays a great role in protection of the electrical appliances and at the same time, electrical energy is saved and the socket is convenient to use.
Description
[technical field]
The utility model relates to a kind of appliance socket, particularly a kind of socket with power-off protection function.
[background technology]
Various supply sockets are arranged now on the market, these sockets have with switching function, can disconnect or switch on power, to electricity consumption, a lot of convenience have been brought, but these switches are once must the people manually cut out after connecting, otherwise will be in for a long time on-state, with the socket that there is no belt switch, be as good as, it is no problem ground that this socket is used under normal circumstances, when but after once occur, having a power failure, a period of time sends a telegram here again, just there are a lot of risks, if the power supply failed when using hair dryer, and forgotten afterwards the pass hair dryer, while sending a telegram here again, just may cause fire to go out, or other electrical equipment while after power failure, sending a telegram here again voltge surge also may cause electrical equipment to burn out even to cause fire and go out.
[summary of the invention]
The purpose of this utility model is to overcome deficiency of the prior art; a kind of power-off protection socket with power-off protection function is provided, and it can be had no progeny in Power supply, when incoming call restores electricity again; after power-on button need to manually be pressed resetting, could continue power supply.
The purpose of this utility model is achieved in that it comprises the housing be comprised of bonnet and protecgulum and is arranged at the pcb board in described housing, on described pcb board, be provided with power supply and socket brush, on the position of described protecgulum respective socket brush, be provided with the brush jack, its improvements are: on described pcb board, also be provided with normally opened contact relay and power-on button.
In said structure, described power-on button be series between power supply and relay one end after the normally opened contact of relay is in parallel, the other end of relay is electrically connected on the socket brush.
In said structure, described power-on button is for often driving button.
In said structure, the brush jack on described protecgulum forms at least one bipod jack and/or tripod jack.
In said structure, the upper end of described power-on button stretches out in the surface of protecgulum.
Compared with prior art; the beneficial effects of the utility model are: on the pcb board in housing, be provided with relay and power-on button; but automatic disconnection power supply after socket has a power failure; while sending a telegram here again; must people's craft press power-on button and just can make the socket brush energising on socket, prevent from going out because energising or voltge surge suddenly cause electrical equipment to damage even to burn the initiation fire, and electrical appliance is played a very good protection; simultaneously can also save power supply, and easy to use.
[accompanying drawing explanation]
Fig. 1 is front schematic view of the present utility model;
Fig. 2 is structural representation of the present utility model.
[embodiment]
Below in conjunction with the drawings and the specific embodiments, the utility model is described further:
As depicted in figs. 1 and 2, power-off protection socket of the present utility model, comprise the housing formed by bonnet and protecgulum 2 and be arranged at the pcb board 1 in described housing, on described pcb board 1, be provided with power supply 6 and socket brush 5, on the position of described protecgulum 2 respective socket brushes 5, be provided with the brush jack, described brush jack forms at least one bipod jack 7 and/or tripod jack 8; On described pcb board 1, also be provided with normally opened contact relay 4 and power-on button 3, described power-on button 3 is for often driving button, its upper end stretches out in the surface of protecgulum 2, and be series between power supply 6 and relay 4 one ends after the normally opened contact of relay 4 is in parallel, the other end of relay 4 is electrically connected on socket brush 5.
Its operation principle is: after power-off protection socket of the present utility model is accessed to civil power, power supply 6 energisings, click power-on button 3,4 adhesives of circuit working relay, socket brush 5 energisings in bipod jack 7 and triangle jack 8, click power-on button 3, relay 4 disconnects again, and the power supply of the socket brush 5 in bipod jack 7 and triangle jack 8 disconnects; When power supply 6 nothing electricity; pcb board 1 non-transformer is without work; the normally opened contact of relay 4 is in normally open; after power supply 6 energisings; pcb board 1 obtains electric work; but during not by power-on button 3; relay 4 still is in normally open; socket brush 5 in bipod jack 7 and triangle jack 8 still is in without power supply state; need to press power-on button 3 and just can make 5 energisings of socket brush; avoided being plugged on electrical appliance on socket and because suddenly energising or voltge surge cause electrical equipment to damage, even burnt and cause fire and go out, electrical appliance has been produced to good protective effect.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although in this specification, used some specific terms, these terms just for convenience of description, do not form any restriction to the utility model.
