Description
Technical field: the utility model relates to a kind of battery saving arrangement, relates in particular to a kind of energy-saving automatic plate.
Background technology: modulator-demodulator and router are the indispensable key equipments of computer network, because its power consumption is less, many users often do not close the modulator-demodulator power supply in order to save trouble later at shut down of computer, and let alone unlatching in 24 hours.Yet along with popularizing of computer network, the usage quantity of modulator-demodulator and router also rises thereupon; Add up according to interrelated data, the power consumption of annual modulator-demodulator of China and router is about 8,000 ten thousand degree at present, the waste that this shows electric power is quite surprising, therefore is badly in need of a kind of device that can cut off modulator-demodulator and router power supply after shut down of computer automatically.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide the energy-saving automatic outage plate that a kind of shut down of computer can cut off later modulator-demodulator and router power supply automatically.
To achieve these goals, the utility model by the following technical solutions: it comprises electric socket and modulator-demodulator; The signal lamp of modulator-demodulator is connected with diode, first resistance, second resistance and photoelectrical coupler successively, and first electric capacity is with signal lamp and diode parallel connection, and second electric capacity is connected in parallel between the signal lamp and first resistance; A low presser feet of photoelectrical coupler is connected with the base stage of triode, another low presser feet is connected with the collector electrode of triode, the emitter of triode is connected with relay, the collector electrode of triode is connected to integrated package of pressure-stabilizing, and the 3rd electric capacity that is connected to reference to the ground end is connected with the collector electrode of triode; The contact switch of relay and the switch in parallel of electric socket.
Compared with the prior art, the utility model is owing to adopted technique scheme, utilize the phenomenon that the signal lamp of modulator-demodulator and router extinguishes after the shut down of computer, also be cut to the wiring board power supply of modulator-demodulator and router power supply automatically by the action of photoelectronic coupler control relay, thereby reach the purpose of electrical energy saving; In addition, the power supply that cuts off modulator-demodulator and router behind the shut down of computer also can prolong the useful life of modulator-demodulator and router.

3One terminate between triode Q collector electrode and the integrated package of pressure-stabilizing 2, the other end is connected to reference to the ground end; The contact switch K of relay 4
2K switch with electric socket 3
1In parallel.
Operation principle: the K switch of pressing electric socket 3 after computer is opened
1, electric socket 3 is to modulator-demodulator power supply, the signal lamp d of modulator-demodulator
1Luminous work, photoelectrical coupler 5 work, triode Q conducting, relay 4 gets electric, contact switch K
2Adhesive; And then click K switch
1, make K switch
1The disconnection of upspringing, this moment, electric socket 3 was by contact switch K
2Still keep conducting and continue and power to modulator-demodulator.After the brain shutdown, signal lamp d
1Extinguish, photoelectrical coupler 5 quits work, and triode Q ends, relay 4 dead electricity, contact switch K
2Disconnect, electric socket 3 open circuits also block the power supply of modulator-demodulator.
