Abstract

Disclosed is a safety socket which relates to the improvement of a socket structure. The utility model provides a safety socket which can save electric energy and guarantee that no voltage is outputted when no plug is plugged in the socket. The safety socket comprises a strong magnetic sheet and a socket, and a dry reed tube is arranged inside the socket. One line of a power source of 220V alternating current is connected with an input end of a rectifier bridge through a resistance-capacitance depressurization circuit, the other line is in series connection with a contact point of a relay andan output end of the socket, an output end of the rectifier bridge is connected with an input end of a transformer, and an output end of the transformer is in series connection with a diode, the dry reed tube and a coil of the relay.

Description

A kind of safety socket

Technical field:

The utility model relates to the improvement of socket.

Background technology:

In daily life,, child's family is especially arranged, easier initiation electric shock accidents in the family owing to the electric shock accidents that people's carelessness causes is more common; And wherein, socket exists great potential safety hazard.

Existing anti-electric shock socket adopts and at the jack place of socket the generation that catch prevents electric shock accidents is set.When not having plug to insert, block by the jack of catch with socket; Though this kind anti-electric shock socket can avoid child will point in the jack that inserts socket to a certain extent; But when child inserts the jack of socket with electric conductor, still have voltage output, cause unnecessary loss for people's life, property.

The utility model content:

The utility model is exactly at the problems referred to above, but the safety socket of no-voltage output when providing a kind of saves energy, no plug to insert.

For achieving the above object, the utility model adopts following technical scheme, the utility model comprises strong magnetic piece, socket, in socket, be provided with tongue tube, 220V alternating-current power supply one tunnel links to each other with the input of rectifier bridge through the resistance-capacitance depressurization circuit, the contact of another road and relay, the output of socket are connected in series, and the output of rectifier bridge links to each other with the input of transformer, and the coil of the output of transformer and diode, tongue tube, relay is connected in series.

The beneficial effects of the utility model:

But 1 saves energy:

Because the input at rectifier bridge of the present utility model also is in series with a tongue tube K1; When socket of the present utility model does not have plug to insert, the not conducting of tongue tube K1 in the socket, the not conducting of control circuit in the socket, consumed power has not been saved electric energy;

No-voltage output when 2, no plug inserts:

Because the utility model comprises strong magnetic piece, socket, in socket, be provided with tongue tube, 220V alternating-current power supply one tunnel links to each other with the input of rectifier bridge through the resistance-capacitance depressurization circuit, the contact of another road and relay, the output of socket are connected in series, the output of rectifier bridge links to each other with the input of transformer, and the coil of the output of transformer and diode, tongue tube, relay is connected in series; Just make socket of the present utility model no-voltage output when not having plug to insert, effectively avoided child will point the electric shock accidents that causes in the jack that inserts socket; And when child inserted the jack of socket with electric conductor, still no-voltage was exported, and had guaranteed child's life security.

Description of drawings:

Fig. 1 is circuit theory diagrams of the present utility model.

Embodiment:

The utility model comprises strong magnetic piece, socket, in socket, be provided with tongue tube K2,220V alternating-current power supply one tunnel links to each other with the input of rectifier bridge via the resistance-capacitance depressurization circuit that resistance R 1, capacitor C 1 are formed in parallel, the contact of another road and relay J, the output of socket 1 are connected in series, the output of rectifier bridge links to each other with the input of transformer, and the coil of the output of transformer and diode VD1, tongue tube K2, relay J is connected in series.

For saves energy, also be in series with a tongue tube K1 at the input of rectifier bridge.

The output of the transformer that links to each other with the positive pole of diode VD1 links to each other with the positive pole of light-emitting diode VD2, and the negative pole of light-emitting diode VD2 links to each other with another output of transformer through resistance R 3; Whether light-emitting diode VD2 is used for the reminds people socket voltage output.

During use, earlier strong magnetic piece is installed in the plug of power consumption equipment.When with plug insertion socket, in plug under the effect of strong magnetic piece, tongue tube K1, K2 conducting, relay J gets electric, the contact adhesive of relay J, the output 1 of socket has voltage output, the power consumption equipment operate as normal, light-emitting diode VD2 is luminous.When plug was extracted socket, tongue tube K1, K2 disconnected, the relay J dead electricity, and the contact of relay J disconnects, the output 1 no-voltage output of socket, light-emitting diode VD2 extinguishes, thereby has effectively avoided the generation of electric shock accidents.
