Description

The sensor-type all-electronin switch of decoration type

The sensor-type all-electronin switch of a kind of decoration type belongs to electronic technology field.

Existing civilian single phase poaer supply switch generally adopts pileup type and button two major types, and its construction of switch mainly is made up of touch spring, mechanical transmission mechanism and spring, with hand pull or with hand by contact being closed or disconnecting, reach the purpose of on-off circuit.Because switch push-key or button place the switch surface, are movable part, therefore can not become totally enclosed type, beautifying and decorating also can't be carried out in the switch surface.The switch surface does not have the on off state indication, and is very inconvenient in the use at night, because not clear on off state causes error sometimes again easily.Induction type touch switch was once arranged on the market, and its circuit is simple, is subjected to the external interference misoperation more, and power is little, versatility is poor, and sensitive surface is also very little, can't the decoration.Goal of the invention of the present utility model is to provide a kind of decoration type sensor-type all-electronin switch, the switch surface is a totally enclosed type, can dust and moisture, can make various beautifying and decoratings again, as long as any part the opening or closing that human body touches the switch surface decoration with regard to the may command circuit.When switch disconnects, the function of low-light indication is arranged on the panel.So can make switch both safe and practical, attractive in appearance again, have artistry.

For realizing such goal of the invention, the inventor is embedded with the decoration of a slice electric conducting material through art up processing on the switch surface, and be equipped with the indicator light loophole, the conduction decoration contacts with elastic contact chip pressure in the switch, and the high value isolation resistance in the connection electronic circuit, the signal of telecommunication of human body contact conduction decoration induction is realized opening or closing of control circuit by specially designed electronic circuit.

Fig. 1 is the sensor-type all-electronin switch panel of a decoration type outline drawing.At positive middle a slice conduction decoration 2 that is embedded with of switch plastic front board 1, the indicator light loophole is left in the upper end.

Fig. 2 is the left view of Fig. 1.Take among the figure and collude 3 in order to connect switch baseplate.

Fig. 3 is that the utility model is installed base plate and switch core constitutional diagram.Two installing holes 7 are arranged on the base plate 5, taking in four hasps 6 and the accompanying drawing 2 colluded 3 and installed and be connected, electronic circuit board is contained in the switch core 10, the surface seals with cover plate 9, indicator light 11 and elastic contact chip 8 are arranged on the cover plate 9, and elastic contact chip 8 and the contact of conduction decoration 2 pressure also are connected with high value isolation resistance in the electronic circuit.Switch core 10 usefulness screws 4 are fixed on the base plate 5.

Fig. 4 is the left view of Fig. 3, has binding post 12 to connect the internal electron circuit at switch core 10 rear sides, and the A hole connects the 220V phase line in the binding post, and outlet of B hole and load one end join, load other end connecting to neutral line.When human body touched conduction decoration 2, because conduction decoration 2 contacts with elastic contact chip B pressure, then the induced signal of human body just was input to control circuit by the high value isolation resistance that is connected with elastic contact chip 8.

Fig. 5 is a profile stereogram of the present utility model.

Fig. 6 is the utility model electronic circuit block diagram.Comprise the rectification electronic switch 13 of holding concurrently in the electronic circuit of the present utility model, electric leakage low pressure source of stable pressure 14, self-locking bistable amplifier 15 and high value isolation resistance more than 16 parts are formed.The input signal of high value isolation resistance is from conduction decoration 2, and hold concurrently two leading-out terminals of electronic switch 13 of rectification are A, B two ends in the binding post 12, A termination 220V phase line, and the B end is connected with load one end lead-out wire, and load other end lead-out wire connects to zero line.

Fig. 7 provides the utility model electronic circuit schematic diagram.

In the electronic circuit, D1-D4 rectifier bridge, controllable silicon SCR 1 and resistance R 3 have been formed the rectification electronic switch part 13 of holding concurrently, electric leakage low pressure source of stable pressure 14 is made up of diode D5, D6 and capacitor C 2 resistance R 4, self-locking bistable amplifier 15 is by integrated circuit Ic, triode BG1, BG2, resistance R 5-R9, capacitor C 5-C8 forms, and resistance R 10, R11 capacitor C 6, C7 are formed high value isolation resistance 16, the signal that comes from 2 inductions of R11 input conduction decoration.

Under the load powering-off state, end when controllable silicon SCR 1, a minimum leakage current is arranged in the load, through the D1-D4 rectification, produce a ultralow pressure power supply through D5, D6, C2 voltage regulation filtering by the R4 step-down, prepare to the power supply of self-locking bistable amplifier.When controllable silicon SCR 1 was ended, it controlled very low level, and integrated circuit Ic3 pin also is a low level, and triode BG1 is in running order, and BG2 is in reverse voltage to be ended.Induce power frequency component when human body touches conduction decoration 2, R10, R11, the C6 in high value isolation resistance delivers to triode BG1 and amplifies, and produces low level on R6, trigger the Ic2 pin, make the upset of Ic internal circuit, making 7 pin and 3 pin is high level, triggers SCR1 conducting load and gets.Because 3 pin are that high level feeds back to the BG1 emitter, are in working inverse voltage BG1 and end, BG2 is in forward operating voltage state.When input signal must amplify by triode BG2 when R10, the R11 in too high value isolation resistance and C7 once more, trigger the Ic6 pin preset, making the Ic7 pin is low level, controllable silicon SCR 1 is ended, the load outage, and 3 pin are that low level feeds back to the BG2 collector electrode, BG2 is in working inverse voltage, BG2 ends, and BG1 is in forward operating voltage state, waits for input signal again.So, as long as human body skin touches the switch surface conductance and decorates any one position once, just can once open or close by decoration sensing control electronic switch.

Resistance R 2 in the circuit, and capacitor C 1 is used to absorb overvoltage, Ru absorption peak voltage, inductance L can delay peak current, and C3, C4 are anti-interference capacitor, and C5, C8 relax voltage capacitor, indicator light when Ez is the switch disconnection is worked as switch connection, and load energising back Ez promptly extinguishes.

The utility model is controlled electronic switch by the human body sensing power frequency component, strong interference immunity, and the voltage adaptation scope is wide.Because, being convenient to various artistry without any movable part, the switch surface decorates.Decoration can be done as required and do for a short time greatly, can make various art patterns.Can be load of a decoration switch control, also the synthetic complete decoration painting of the decoration switch of several mutually insulateds can be controlled several different loads respectively.Adopted enclosed construction can be moistureproof dustproof, non-contact structure can not produce spark, is provided with that show night and on off state is indicated, safe and convenient to use.
