Abstract
The invention discloses a safety socket, which belongs to the technical field of power sockets, and comprises a control circuit which is arranged in a shell and is formed by a power circuit, a light-emitting diode (VD1), a light-operated audion (VT), diodes (VD2) and a relay (KM). The light-emitting diode (VD1) is connected to the output end of the power circuit in parallel; a negative electrode of the light-emitting diode (VD1) is connected with a collector electrode of the light-operated audion (VT); an emitting electrode of the light-operated audion (VT) is connected with a negative output end of the power circuit through the relay (KM); the diodes (VD2) are connected to the two ends of the relay (KM) in parallel; the light-operated audion (VT) is close to the light-emitting diode (VD1); and an adapter connector of the socket is connected with a normally open contact (KM1) of the relay (KM) in series and then is connected to two ends of a 220V alternating current power supply in parallel. The safety socket has the beneficial effects that: since the socket is started through photoelectricity, the insulation performance is good, and the service life of the socket is prolonged.
Description
Technical field
The present invention relates to a kind of supply socket, specifically is a kind of safety socket, belongs to the supply socket technical field.
Background technology
Common socket all is that the contact of socket directly is connected with power supply, after load-carrying plug is plugged socket, and the load work of just can switching on.The weak point that this socket exists is: the load of socket is excessive, and when plugging in a flash, electric current is excessive, and generation easily causes the accident; Because the insulation property of socket are bad, often opening and closing are prone to cause reduce the useful life of socket.
Summary of the invention
To the deficiency that above-mentioned prior art exists, the present invention provides a kind of and starts through photoelectricity, has the safety socket of safeguard protection effect.
To achieve these goals, the technical scheme of the present invention's employing is: a kind of safety socket comprises the control circuit that is installed in enclosure interior; Control circuit is made up of power circuit, light-emitting diode VD1, light-operated triode VT, diode VD2 and relay K M; Light-emitting diode VD1 is connected in parallel on the output of power circuit; The negative pole of light-emitting diode VD1 connects the collector electrode of light-operated triode VT, and the emitter of light-operated triode VT is connected with the negative output terminal of power circuit through relay K M, and relay K M two ends are parallel with diode VD2; Light-operated triode VT is near light-emitting diode VD1; Be connected in parallel on 220V AC power two ends after the normally opened contact KM1 series connection of the joint of socket and relay K M.
Operation principle: when pressing the button SB, this moment, light-emitting diode VD1 connected luminous.Light-operated triode VT is owing to receive the irradiation of light, light-operated triode VT conducting, and relay K M action, contact KM1 is closed, and the logical 220V AC power that goes up of socket S has played the effect of insulation.Wherein work as vD2 and be the protection diode.
The invention has the beneficial effects as follows: start socket through photoelectricity, good insulation preformance has prolonged useful life of socket.
