Description

Automatically closing power saving switch

The utility model relates to a kind of from closing battery-conserving switch, refers in particular to be used for room, corridor lighting pass, electricity consumption electricity-saving control device regularly certainly.

Known lighting switch connecting and disconnecting of the circuit is by the control of the mechanical contact of its inside, and the illumination in corridor, corridor or the aisle walking of feeling about in the dark because of people are reluctant to turn off the light is usually kept burning day and night all night, causes waste of energy.So in order to economize on electricity is to have the time-delay battery-conserving switch to come out.Existing Electronic Control time-delay mechanism, its circuit itself exist at ordinary times can not break away from electrical network fully, long-term power consumption or partly break away from the defective of micro-power consumption.China utility model patent CN2053999U discloses a kind of " the Subminiature electronic formula does not have power consumption time-delay battery-conserving switch ", this device adopts one-way SCR, because of just not being subjected to the control of triggering signal after its conducting, the break trigger signal still can conducting, also must deenergization if will turn-off.It is not terse that other has some other relevant patent to exist circuit in various degree, and debugging is difficult for, and element is many, defectives such as complete machine cost height.

The purpose of this utility model is to avoid the above-mentioned weak point of prior art, and provide switch of a kind of mat simultaneously control load break-make and the path of breaking circuit own, contactless, can not produce and disturb electric wave, easy to use, cost is low, easy making need not be debugged the battery-conserving switch of pass certainly.

Task of the present utility model is finished by following technical measures.

The utility model is made up of capacitor step-down rectifier circuit, filter circuit of pressure-stabilizing, 555 o'clock base circuits for triggering, RC time constant circuit, button switch K and insulation shells, between load and zero line, be connected to SCR bidirectional triode thyristor (see figure 1), bidirectional triode thyristor SCR and load RL series connection, be connected in again between live wire and the zero line, be the line of starting to exchange fire on the load RL, the T of bidirectional triode thyristor SCR ₁Utmost point connecting to neutral line.Control the break-make of 220V circuit,, play the economize on electricity effect to reach regularly switching off load and circuit itself.C ₁, DW, D ₁And C ₂Form the rectifying and voltage-stabilizing filter circuit, time-base circuit 555 is connected into single-shot trigger circuit, and output triggers positive pulse signal, triggers the conducting of SCR bidirectional triode thyristor, lights bulb, R ₂C ₃Time constant circuit is controlled the upset of monostable trigger-action circuit by 1.1 * R.C time, reaches the purpose of time-delay control.

The startup of circuit is connected circuit with one or many button switch K, and lamp is bright, and 555 time-base circuits begin when slow, decontrol switch, circuit is because of bidirectional triode thyristor conducting self-insurance, and delay circuit still, when the 555 time-base circuits upset of delaying time, output low level is turn-offed bidirectional triode thyristor.

Starting switch K is connected in parallel on the T on the bidirectional triode thyristor SCR ₁And T ₂On, playing the startup effect, the break-make of decontroling button circuit is just by bidirectional triode thyristor control, and button switch K is inoperative.

R ₄C ₅Form bidirectional triode thyristor protection networking, physical circuit is with R ₄And C ₅After the series connection, be connected in parallel on the T of bidirectional triode thyristor SCR ₂And T ₁Two ends prevent that the high-frequency pulse voltage that inductive load produces from damaging bidirectional triode thyristor when turn-offing.

The entire circuit element is installed in the insulation shell that plastics or bakelite make.

The utility model compared with prior art has following advantage: the utility model utilizes the break-make of a switch while control load and circuit, reaches purpose of saving.Need not change former illuminating line road and can directly replace the moving switch of used wall slab, it is very convenient to install.Night illumination or the corridor switch that only needs to push the button up and down, illuminating lamp is promptly bright, and after tens of seconds to several minutes, illuminating lamp extinguishes automatically.This installs also automatic disconnection electrical network, circuit itself is consumed power not at ordinary times, be fit to closing automatically of power supplys such as the lighting in places such as room, bedroom, hotel, hostel corridor and electrical equipment, have circuit simple, easily install, need not debug, distinguishing features such as volume is little, cost is low, easy to use, durable in use and economize on electricity.

The explanation of accompanying drawing drawing:

Fig. 1 is a circuit diagram of the present utility model.

Fig. 2 replaces the schematic diagram of former operating switch for the utility model.

Following the utility model will describe in detail embodiment (in conjunction with the accompanying drawings).

The utility model (see figure 1) is made up of capacitor step-down rectifier circuit, filter circuit of pressure-stabilizing, 555 o'clock base circuits for triggering, RC time constant circuit, button switch K and insulation shells, and the SCR bidirectional triode thyristor is connected between load and the zero line, R ₄C ₅Form bidirectional triode thyristor protection networking, the starting switch K of RC timing circuit is connected in parallel on the SCR bidirectional triode thyristor.

Press the button K, power on circuitry, 220V is through C ₁(0.47M/400V) step-down, voltage-stabiliser tube DW(9V) voltage stabilizing, D ₁(1N4007) diode rectification is through C ₂(470M, 16V) filtering is exported a galvanic current and is pressed, supply control circuit, and illuminating lamp RL is luminous simultaneously.Circuit gets electric back 555 time-base circuits output high level, triggers bidirectional triode thyristor SCR conducting; After decontroling button, circuit and illuminating lamp keep electricly with bidirectional triode thyristor SCR conducting, are in on-state; When predetermined delay time then, 6 pin current potentials of 555 time-base circuits reach 2/3 when above of supply voltage, 555 time-base circuit output low levels are turn-offed bidirectional triode thyristor SCR, lamp extinguishes, itself also turn-offs circuit.

The utility model can directly replace the moving switch of used wall slab, need not change circuit.Fig. 2 is seen in the repacking wiring.The tie after dotted line is represented to reequip is taken off former circuit in X shown in Fig. 2 number expression from switch.A represents former operating switch upstairs, and B represents former operating switch downstairs.
