Abstract

The utility model discloses a power socket with overheating protection. The power socket with overheating protection comprises a shell composed of a front cover and a front cover, and a PCB (printed circuit board) arranged in the shell, wherein a power supply and a socket electric brush are arranged on the PCB, and an electric brush jack is formed in a position corresponding to the socket electric brush, on the front cover. The power socket with overheating protection is characterized in that a normally-open contact relay, an electrifying button, a temperature sensor and a temperature control circuit are further arranged on the PCB. According to the power socket with overheating protection disclosed by the utility model, the relay, the electrifying button, the temperature sensor and the temperature control circuit are arranged on the PCB in the socket; when power is failed or a temperature in the socket exceeds a set value, the power supply of the socket can be automatically switched off; and after power is recovered or the temperature is recovered, the socket electric brush on the socket can be electrified only by manually pressing the electrifying button instead of automatic power supply, so as to prevent a fire caused by the damage and even burn-out of an electric appliance due to sudden electrifying or voltage surge, thus acting a great protection effect on the electric appliance; simultaneously, power source can also be saved; and moreover, the power socket with overheating protection is convenient to use.

Description

Supply socket with overtemperature protection
[technical field]
The utility model relates to a kind of appliance socket, particularly a kind of supply socket with overtemperature protection.
[background technology]
Various supply sockets are arranged now on the market; these sockets have with switching function; can disconnect or plugged; bring a lot of convenience to electricity consumption; but these switches are once must the people manually cut out after connecting; otherwise will be in for a long time on-state; be as good as with the socket that does not have belt switch; it is no problem ground that this socket uses under normal circumstances; but once high-power electric appliance running hours socket occurs fever phenomenon may appear; when excess Temperature, may cause the insulating barrier of cable circuit to damage; may cause socket to burn even cause fire and go out; and often only on high-power socket, just have for overheating protection circuit; be that common power distributor does not all have overheat protective function for wall jack commonly used; this can't distinguish high-power and small-power for a domestic consumer at all, so there is the danger that much causes because circuit is overheated in routine use.
[summary of the invention]
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of supply socket with overtemperature protection with power-off protection and overheat protective function is provided.
The purpose of this utility model is achieved in that it comprises the housing that is comprised of bonnet and protecgulum and is arranged at pcb board in the described housing, be provided with power supply and socket brush on the described pcb board, be provided with the brush jack on the position of described protecgulum respective socket brush, it is characterized in that: on described pcb board, also be provided with normally opened contact relay, power-on button, temperature sensor and temperature-control circuit.
In the 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 the said structure, described temperature sensor is connected with the input of described temperature-control circuit, and the output of described temperature-control circuit is connected with relay.
In the said structure, the brush jack on the described protecgulum forms at least one bipod jack and/or tripod jack.
In the said structure, be equipped with a temperature sensor in the middle of two holes of described each bipod jack, be provided with a temperature sensor in the middle of three holes of each tripod jack.
In the said structure, described power-on button is for often driving button.
In the said structure, the upper end of described push button stretches out in the surface of protecgulum.
Compared with prior art; the beneficial effects of the utility model are: the pcb board in socket is provided with relay; power-on button; temperature sensor and temperature-control circuit; when the temperature in power failure or the socket surpasses set point; but the power supply of automatic disconnection socket; when sending a telegram here again or temperature can automatic power after recovering yet; must people's craft press power-on button and just can make socket brush energising on the socket; prevent from causing fire and going out because suddenly energising or voltge surge cause electrical equipment to damage even burn; electrical appliance is played a very good protection; simultaneously can also save power supply, and easy to use.
[description of drawings]
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, supply socket with overtemperature protection of the present utility model, comprise the housing that is formed by bonnet and protecgulum 2 and be arranged at pcb board 1 in the described housing, be provided with power supply 6 and socket brush 5 on the described pcb board 1, be provided with the brush jack on the position of described protecgulum 2 respective socket brushes 5, 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, power-on button 3, temperature sensor 9 and temperature-control circuit 10, 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 the socket brush 5; Described temperature sensor 9 is connected with the input of described temperature-control circuit 10, and the output of described temperature-control circuit 10 is connected with relay 4 one ends.
Wherein, the quantity of described temperature sensor 9 is the quantity that bipod jack 7 adds tripod jack 8, be provided with a temperature sensor 9 in the middle of two holes of each bipod jack 7, be provided with equally a temperature sensor 9 in the middle of three holes of each tripod jack 8, guarantee to confirm accurately whether the temperature of socket is too high.
The operation principle of its power-off protection is: after with power-off protection socket access civil power of the present utility model, power supply 6 energisings, click power-on button 3,4 adhesives of circuit working relay, socket brush 5 energisings in bipod jack 7 and the 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 the 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 gets 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 the 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 the socket and caused electrical equipment to damage because of suddenly energising or voltge surge even burn and cause fire and go out, electrical appliance has been produced good protective effect.
