The energy-saving time-delay electronic switch can be controlled optionally to delay time by users. The utility model is an ideal energy-saving time-delay electronic switch which is suitable for popularization, and the utility model has good social benefit and economic benefit.
Description
A kind of delay electronic switch belongs to the electronic switch field.
The delay electronic switch of market appearance at present, most product is to utilize time-base circuit to make the timing controlled device, cooperating controllable silicon or relay to control power device again carries out energy-conservation, or utilize capacitance-resistance regularly to make controller, its product all coincidentally increases the pair of switches control line and makes to trigger timer work line, thereby make product install produced to correctly distinguish the lead-in wire and be connected complicated problems, the circuit that will comprehensively change especially, it is big that these products exist the option volume, small product size also increases thereupon, a series of shortcomings such as price height.
The purpose of this utility model is in order to overcome the weak point of prior art, energy-conservation delay electronic switch is designed to miniature, low-cost, the easy two terminal device (two ends can be changed arbitrarily with circuit and are connected) of installation, has the advantages that arbitrarily controlled by the user.
The purpose of this utility model can reach by following measure.The utility model comprises a bridge rectifier, it is characterized in that capacitor C and resistance R
1Serial connection, R
1With the anode series of controllable silicon SCR, the base stage b of triode VT is connected on capacitor C and R
1Between, emitter e is in parallel with the negative electrode of the capacitor C other end and controllable silicon SCR, and collector electrode c connects resistance R with the control utmost point of controllable silicon SCR
2Be connected on R
1And between the SCR, the other end is connected between the control utmost point of the collector electrode C of VT and SCR.Described delay electronic switch in order to reach delay effect, is to utilize to strengthen capacitor C and resistance R
1Value, electric capacity is charged at a slow speed, make the capacitor C repid discharge by three loops then, when disconnecting to be implemented in circuit, the pressure drop on the electric capacity reduces rapidly, wherein, capacitor C, R
1, SCR is first loop; Capacitor C, base stage b, collector electrode c, resistance R
2, SCR is second loop; Capacitor C, base stage b, emitter e are tertiary circuit.
The utility model can also reach by following measure.Capacitor C adopts electrochemical capacitor, its positive terminal and resistance R
1Series connection.
Below in conjunction with accompanying drawing principle of the present utility model, installation and operation are described in detail.
Description of drawings is as follows:
Fig. 1 is a circuit diagram of the present utility model.
Fig. 2 is a kind of outline drawing of the present utility model.
Fig. 3 is a tandem connection of the present utility model.
Fig. 4 is a parallel connection of the present utility model.
As shown in Figure 1, electric current flows through the bridge rectifier rectification from the AB end, produces the all-wave pulsating dc voltage at the controllable silicon SCR two ends, and voltage is through R
2Be added to the SCR control utmost point and make the SCR conducting, the voltage drop after the conducting is about 1.5V～2V, and this voltage is through R
1To capacitor C charging, after postponing second through T, the capacitor C terminal voltage reaches the conducting voltage of VT, the VT conducting, and the SCR control utmost point is vised to 0.6V by VT, and SCR disconnects and finishes the function of delay turn-off circuit.To realize that in this circuit outage (circuit loop cut-out) back device has delay feature, its key is that the electric charge in the capacitor C is discharged as early as possible, this circuit is the self discharge that utilizes capacitor C, the b of VT, the electric leakage of the e utmost point, and the electric leakage of SCR (being above-mentioned three loops) discharges, and the velocity of discharge is very fast; Utilize and strengthen capacitor C and resistance R
1Value realize to increase time of charging, utilize simultaneously pulsating voltage be AC rectification and the peculiar null character of crossing carries out release of short duration to the electric charge in the capacitor C, make the voltage of capacitor C be unlikely very fast rising, and obtain the long delay time quantum.In addition, select miniature device and sensitive small-sized SCR for use, make trigger current reduce to minimum,, make power consumption of the present utility model extremely low to obtain best energy-saving effect.The withstand voltage of capacitor C can be low to moderate 0.7 volt, and the capacity of capacitor C can do more a little to obtain longer time of delay like this.
The utility model is quite convenient, flexible in concrete the application, need not increase circuit.The utility model is designated as A, and Fig. 3 is the tandem connection of A.This method can make original K switch
1The pass function keep, and open the control that function will be subjected to A, postpone to open disabler after a period of time.Fig. 4 is the parallel connection of A, and this method can make original K switch
2Function opposite with tandem.
Fig. 3, the 4th installs original family doorway lamp circuit additional the illustration of this switch.Install lamp behind the door as stated above additional, just have the function that delay is turned off the light, it is long bright to reduce gate light, saves energy.Using method after installing is twice Drawing switch in succession, and lamp extinguishes after will lighting a period of time automatically.The time of delay of the time interval may command A of twice Drawing switch, big more at interval, then the time of delay of A is long more.
If rearrange circuit, preferably with K switch
1(or K
2) change button into, adopt parallel connection, can reduce the pulling number of times like this, and only need to push the button, can light gate light, and delay feature is constant, pinned the length of button time time of delay and controlled.
The present invention's compared with prior art have the following advantages (seeing Table)
| Advantage | Volume | Price | Installation difficulty | Time delay | The lead-in wire number | Shape | Other |
| Similar product | Greatly | High | High | Gu the point | Article 4, | Square | Need to change circuit |
| The present invention | Little | Low | Low | 1-2 minute controlled | Article 2, | Various shape | Need not change circuit |
As seen from the above table, the utility model has promotional value.
