Abstract

The utility model relates to a power socket, in particular to a power socket capable of cutting off the power automatically. The power socket capable of cutting off the power automatically is composed of a socket body, a maintaining signal acquisition circuit, a button switch, a voltage-stabilized source circuit, a power-on timing circuit and an execution circuit, wherein the voltage-stabilized source circuit supplies power to a whole control circuit. The maintaining signal acquisition circuit is composed of a mutual inductor, a rectification element and a filter element, when a user presses the button switch, after a computer is started up, the mutual inductor generates induced electromotive force, the induced electromotive force is rectified and filtered, the induced electromotive force is sent to the execution circuit by the maintaining signal acquisition circuit and is absorbed by a relay, and the socket body and the control circuit are powered on. When the system of the computer is turned off, the current on a power line is reduced, the induced electromotive force generated by the mutual inductor decreases, the relay releases the induced electromotive force, and the socket and the control circuit are powered off. Therefore, the automatic power-off function of the socket is achieved after the computer system is turned off, and the problem that standby socket consumes energy is solved. The power socket capable of cutting off the power automatically has the advantages of being safe, saving in energy and capable of prolonging the service life of the computer and the service life of the external devices.

Description

The supply socket that can cut off the power supply automatically

Technical field

The utility model relates to a kind of supply socket, the especially a kind of supply socket that can cut off the power supply automatically.

Background technology

The shutdown of computer has the process of a wait.Normal shutdown just can be cut off the electricity supply after must waiting computer system to close, cumbersome, and forget easily, a lot of users do not wait computer system to close and have just left computer, cause peripheral hardwares such as host computer and display, audio amplifier, printer, scanner to be in holding state for a long time, partial circuit still in work, had both been wasted electric energy, there is potential safety hazard again, also reduces the useful life of computer and peripheral hardware.

Also find at present the socket product that can cut off the power supply automatically, only met the design document of this respect.But the standby energy consumption issues that all have circuit complexity, production cost height, functional reliability is low and the socket itself that cuts off the power supply automatically exists causes not form product.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of simple in structure, easy to use, after computer system is closed, can cut off the supply socket of whole socket and control circuit power supply automatically, solve the standby energy consumption issues of socket own simultaneously.

The technical scheme in the invention for solving the technical problem is: the supply socket that can cut off the power supply automatically comprises socket and control circuit, and control circuit is formed by keeping signal acquisition circuit, push-button switch, voltage-stabilized power supply circuit, the timing circuit that powers on, executive circuit.Voltage-stabilized power supply circuit provides power supply to the The whole control circuit.Keeping signal acquisition circuit is made up of mutual inductor and rectification, filter element, when pressing the button switch, after starting computer, this circuit send executive circuit with the induced electromotive force that mutual inductor produces after rectification, filtering, relay gets electric adhesive, the normally opened contact closure of relay, socket and control circuit get.After computer system is closed, electric current on the power line reduces, the induced electromotive force that mutual inductor produces reduces, relay discharges, the normally opened contact of relay disconnects, the outage of whole socket and control circuit has realized that computer system closes the rear socket purpose of outage automatically, has solved the standby energy consumption issues of socket own.

The utlity model has the beneficial effect in safety, energy savings, prolongation computer and peripheral hardware useful life.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in drawings, the supply socket that can cut off the power supply automatically comprises socket (3) and control circuit, and control circuit is by keeping signal acquisition circuit (1), push-button switch AN(2), voltage-stabilized power supply circuit (4), the timing circuit that powers on (5) and executive circuit (6) form.

Voltage-stabilized power supply circuit (4) provides power supply to the The whole control circuit, and one of its input terminates at push-button switch AN(2) and socket (3) between, be subjected to switch AN(2) and the control of the normally opened contact K of relay J.

Keeping signal acquisition circuit (1) is made up of mutual inductor L, rectifier cell D1, filter element C1 and resistance R 1, phase line in the 220V AC power cord of gang socket body (3) or zero line are connected with socket (3) after passing mutual inductor L, and the signal that mutual inductor L produces send executive circuit (6) after rectification, filtering.

Push-button switch AN(2) with after the normally opened contact K of executive circuit (6) repeat circuit J is in parallel, is serially connected between 220V AC power and the socket (3).

The timing circuit (5) that powers on is made up of inverter F1, F2, capacitor C 4, resistance R 2, and its input links to each other with the output of voltage-stabilized power supply circuit (4), and output links to each other with the input of executive circuit (6) through diode D2.

Before the booting computer, press the button switch AN(2 earlier), control circuit gets electric, the timing circuit that powers on (5) output high level, relay J gets electric adhesive, relay J normally opened contact K closure, socket (3).Release button switch AN(2) after, the time action of timing circuit (5) owing to power on, this state will continue to keep a period of time, finish (to change the value of capacitor C 4 and resistance R 2 up to timing, can change the length of timing, generally can be made as about 5 seconds), being inserted in top host computer and peripheral hardware can start working.

Start computer before timing finishes, the power line that passes mutual inductor L has electric current to flow through, and mutual inductor L produces induced electromotive force, after directly rectification, the filtering, gets a high level, triode V conducting at the input of inverter F3.After this, as long as computer work, triode V will keep conducting.

After computer system is closed, electric current on the power line reduces, the induced electromotive force that mutual inductor L produces reduces, inverter F3 is input as low level, and triode V ends, and relay J discharges, the normally opened contact of relay J disconnects, the outage of whole socket (3) and control circuit has realized that computer system closes the rear socket function of outage automatically, has solved the standby energy consumption issues of socket own.
