Electrical fire often because short circuit, seriously overload, high temperature, electric spark (electric arc) initiation fire that electric leakage, loose contact etc. are produced, if when above-mentioned fault appears in circuit in time with dump, then can reduce the fire occurrence probability significantly, reduce the generation of electrical fire.Electrical appliance was realized by switch or supply socket with being connected mainly of power supply at present, and the supply socket of nowadays using only is used for energized, need artificially the appliances power source plug to be separated with supply socket during disconnection to realize, and need sometimes electric equipment is controlled constantly, cause waste owing to forgetting to cut off the power supply, even cause fire incident.

The utility model content

Technical problem to be solved in the utility model provides a kind of intelligent and safe supply socket, and it is simple in structure, not only can be regularly, and break down or temperature can auto power off when too high when circuit, avoided the generation of electrical fire.

For solving the problems of the technologies described above; the technical solution of the utility model is: the intelligent and safe supply socket; comprise the jack body that has jack; the conducting strip that power line connects in the jack in described jack body forms socket circuit; be provided with timing device, attemperating unit and current foldback circuit in described jack body, described timing device and described attemperating unit are serially connected with in the described socket circuit.

As a kind of optimized technical scheme, described timing device is a timing switch, and described timing switch is provided with adjusting key and display.

As a kind of optimized technical scheme, described attemperating unit comprises an expansion of metal formula thermostat, described expansion of metal formula thermostat comprises bimetal leaf, moving contact and fixed contact, described moving contact is connected with described bimetal leaf, and described bimetal leaf is connected with the heatproof lead respectively with described fixed contact.

As a kind of optimized technical scheme, described current foldback circuit comprise the mistake flow control switch that is serially connected with in the described socket circuit and over-current detection element, to the output current of described over-current detection element with set electric current and compare the described over-current control circuit of crossing the flow control switch break-make of back output signal control.

As a kind of optimized technical scheme, described flow control switch excessively is a bipolar transistor, and described over-current detection element is a current sensor.

After having adopted technique scheme, the beneficial effects of the utility model are:

1. owing in jack body, be provided with timing device, it specifically can be a timing switch, timing switch is provided with adjusting key and display, therefore can set the time of opening and closing as required, automatically open at the appointed time, can auto power off when arriving setting-up time, not only accomplished making the Based Intelligent Control of electrical appliance, and can electrical energy saving, can avoid the generation of the fire incident that may cause owing to forget deenergization.

2. be provided with attemperating unit in the jack body; when electrical appliance being hindered for some reason or owing to making for a long time the circuit heating make temperature rise to the operating temperature of attemperating unit setting; attemperating unit can move open circuit rapidly; not only protected electrical equipment, and the fire incident that may cause prevention is in rudiment.When protected apparatus failure is removed or line temperature when dropping to the reset temperature value of attemperating unit, the attemperating unit energized that resets, electrical equipment recovers operate as normal.

3. in jack body, also be provided with current foldback circuit; when short circuit and big electric current appear in supply socket itself or external connection electrical apparatus, in time cut off the electricity supply and avoid causing unnecessary loss; after the condition that causes short circuit and big electric current disappeared, the utility model supply socket can be resumed work automatically.
