Description

Multifunctional electronic energy-saving switch

The utility model belongs to the lighting lamp switching device.

In order to solve corridor, the corridor, places such as toilet " altar lamp " waste problem, multiple energy-saving electronic switch with delay cut-off function has appearred in recent years, its circuit all is by rectification circuit basically, RC delay circuit, formations such as reverse-blocking tetrode thyristor circuit, this exists bigger contradiction aspect two to these switches in the multi-functional and convenience used, so that be difficult to popularize and promote.Use a switch to realize the delay cut-off function as Chinese patent CN2095515U disclosed " multifunction switch ", be provided with another switch again in order to realize functions such as " having regular tap concurrently ".And for example Chinese patent CN2099844U disclosed " power down switch that can manually close in the time delay " also is to use a switch to realize delay function, uses another switch to realize artificial closing function.Though these two kinds of power down switch functions are more, can adapt to multiple operating position and occasion, but operation is too complicated, do not meet popular use habit, and another kind of switch, as Chinese patent CN2064933U disclosed " time-delay Automatic pull switch " though easy and simple to handle, also meet popular use habit, but have only single delay cut-off function, can not adapt to multiple operating position and occasion.

The purpose of this utility model just provides a kind of and needs switches of control (pulling switch or key switch) just can realize delaying time to cut off the power supply automatically, instant manually outage, and the energy-saving electronic switch of function such as normally-open normally-close, such switch is easy to use, adapt to multiple operating position and occasion, volume is little, cost is low, and is easy for installation, is easy to popularize.

In order to achieve the above object, the technical solution that the utility model adopts is: on common controllable silicon delay switch circuit, increased the trigger impulse detecting circuit, pulse strobe circuit, the on off state testing circuit, controllable silicon discharge circuit and one are the trigger switch K that lockable can not lock again to closure state.The on off state testing circuit can be exported different signals in order to the control impuls gating circuit according to controllable silicon SCR 1 residing conducting or off state, the every closure of K switch once, the pulse detecting circuit will be exported a pulse signal, if at this moment SCR1 is in off state, then the output signal of on off state testing circuit will be in the blocking-up attitude by the control impuls gating circuit, pulse signal can not be amplified by gating circuit, controllable silicon discharge circuit (SCR2) can not obtain enough pulse-triggered electric currents, so SCR2 will be in the pass off-state, thereby controllable silicon delay switch circuit (SCR1, R ₅, C ₂Deng) can realize conducting and time-delay automatic circuit break function.If before the K closure, controllable silicon SCR 1 has been in conducting state, and then the output signal of state detection circuit will be in magnifying state by the control impuls gating circuit, and the pulse signal that produces when making K closed can be amplified by pulse strobe circuit, and be used to control the SCR2 conducting, make delay capacitor C ₂On electric weight discharge, cause SCR1 to turn-off, thereby realized instant closing function.If make K be in the closed-lock attitude, then controllable silicon SCR 1 or SCR2(depend on the preceding residing state of circuit of K closure) just can be in conducting for a long time, promptly realized normally closed function.

The pulse detecting circuit is by R ₁, R ₂, R ₃, C ₁Form R ₁Termination power negative pole E point, another terminating diode D ₅Anodal B point, C ₁A termination B point, the other end and R ₂, R ₃Link to each other R ₂Another termination E point, R ₃The base stage of another termination triode T.Before the trigger switch K closure, B point current potential is identical with the E point, and the A point has positive voltage, so if K is closed, then B point current potential will be undergone mutation, this pulse signal is through R ₁, C ₁After the differential circuit shaping of forming, at R ₂Two ends can obtain a sharp-pointed direct impulse, and such poop signal is through R ₃Suitably after the decay, be transported to the base stage of triode T.

Pulse strobe circuit is by triode T and R ₄Constitute, wherein the base stage of T and R ₃Join collector electrode and R ₆, C ₃Join emitter and R ₄And the control utmost point of SCR2 joins R ₄The other end link to each other with the E point.Arrive the base stage of T when poop after, if at this moment the collector electrode of T is in electronegative potential, then T does not have the electric current amplifying power, and the electric current that flows out from emitter equals from the electric current of base stage inflow, because R ₃, R ₄Attenuation, the very faint deficiency of electric current that make to flow into the SCR2 control utmost point makes the SCR2 conducting.When if poop arrives the base stage of T, the collector electrode of T is in high potential, then T has the electric current amplifying power, its emitter can be exported the electric current that is far longer than base current, be enough to make the SCR2 conducting, as seen only need the height of control T collector potential, in the time of just can making K closed, SCR2 is in conducting or off state.

The on off state testing circuit is by R ₆, C ₃Constitute R ₆An end link to each other with the collector electrode of T, the other end extremely links to each other C with the control of SCR1 ₃An end link to each other with power cathode E point, the other end links to each other with the collector electrode of T.When SCR1 turn-offed, its control electrode potential was 0, so C ₃On voltage also be 0, so the collector electrode of T is in electronegative potential.When the SCR1 conducting, its control electrode potential will rise to about 1.0V, and this current potential is through R ₆Be delivered to the collector electrode of T, make the collector potential of T also rise C thereupon ₃Play effect aspect two at this: the one, delay the collector potential rate of climb of T, when making K closed if SCR1 by shutoff become conducting then the collector electrode of T can not set up high potential immediately, thereby guaranteed SCR1 conducting reliably; C ₃Another effect be to store enough energy, when next trigger impulse is arrived (K more closed one time time), can provide enough electric currents to the collector electrode of T, make the reliable conducting of SCR2.

The controllable silicon discharge circuit is made of SCR2, its anode and C ₂Positive pole link to each other, negative electrode links to each other with power cathode E point, the control utmost point links to each other with the emitter of T, when it controlled the bigger trigger current of utmost point acquisition one, SCR2 meeting conducting was with C ₃The electric weight of last storage discharges.

One of trigger switch K is terminated at the anodal A point of power supply after the rectification, and the other end is connected to D ₅Anodal B point.

D ₁-D ₄Constitute bridge rectifier, the on-off of dc pulse current after the control rectification is with regard to opening or closing of alternating current on the controllable load, D ₅, C ₂, R ₅, SCR1 constituted the controllable silicon delay switch circuit.If SCR1 was in off state when K was closed, then trigger impulse can not make the SCR2 conducting, and dc pulse current passes through D ₅To C ₂Charging, C ₂Both end voltage rises, and passes through R simultaneously ₅The control utmost point to SCR1 provides electric current , when

Increase to a certain degree back SCR1 conducting.Because controllable silicon exists

Hour conducting needs a breakover voltage, so contain the poop of higher (more than the 10V) in the voltage waveform that A is ordered, this pulse makes C ₂Can obtain the above direct voltage of 10V, this voltage provides

Greater than keeping the required minimum of SCR1 conducting

So if K does not disconnect, then SCR1 can keep conducting, if K disconnection, then C ₂On electric weight pass through R ₅Discharge, after after a while, Be reduced in the time of can not keeping the SCR1 conducting, SCR1 turn-offs, and has promptly realized delay cut-off.If SCR1 had been in conducting state, then trigger impulse may command SCR2 conducting, C when K was closed ₂Last electric weight is discharged rapidly, so SCR1 transfers closed condition to, at this moment as long as do not disconnect K, then SCR2 will keep conducting state, and it is open-minded that circuit still can keep, if disconnect K this moment, then circuit transfers shutoff immediately to, can realize closing immediately.

Control switch K can use and anyly both can lock the switch that also can not lock to closure state, as the key switch of with locking mechanism, or through the pulling switch of repacking.

Above-described each several part circuit and switch element have just constituted the utility model multifunction electronic power down switch, and it has the following advantages:
