Abstract
The utility model relates to an electronic flashing device which is connected with an indicating lamp, a turning switch and an automobile power source in series. The utility model comprises an outer shell multivibrator and a power switch, and the outer shell multivibrator can fetch out two wire connecting terminals. Because the ic and the bg can form a direct coupling, so the feedback of the current and the voltage can be formed, the balance result can make the galvanic potential between the both ends of A, B stabilize in 2V or so, and the working voltage of a turning lamp DZ can decrease to 2V or so; thereby, the service life of turning light can be prolonged. The gaff impulse interference of the automobile circuit is absorbed by capacitance C1, so the reliable work and the stable frequency can be achieved.
Description
Signal control device when the utility model relates to motor turning, reversing.
" contactless flasher " of the patent No. 89211802.4, all in running order when pole changer is open close, consumed energy influences the Der Blink und Abblendschalter life-span.
The purpose of this utility model be invention a kind of Der Blink und Abblendschalter is not in running order when disconnecting pole changer, do not consume, thereby prolonged the Der Blink und Abblendschalter in the life-span of Der Blink und Abblendschalter.
Task of the present utility model is finished by following mode, and it is a kind of Der Blink und Abblendschalter that is cascaded with indicator lamp, pole changer, automobile power source, and by the shell of drawing two connection terminals, multi-vibrator and power switch pipe are formed.One end of shell is connected with automobile power source, and the other end is connected with the pole changer center-point, and when pole changer was connected, Der Blink und Abblendschalter was started working, and multi-vibrator power controlling switching valve is made periodic switch, thereby the control indicator lamp is bright dark.
Fig. 1 is the outside drawing of the utility model all-electronin Der Blink und Abblendschalter.
Fig. 2 is the electronic-circuit diagram of the utility model all-electronin Der Blink und Abblendschalter.
IC time base circuit and R
1, R
2, capacitor C
2Form and make astable multivibrator, the 3 pin output square wave of IC is controlled the conducting of triode BG and is ended.1 pin of IC connects the lead-out terminal B as Der Blink und Abblendschalter with the collecting electrode of triode BG, the connection terminal A of Der Blink und Abblendschalter is connected with car direct current power supply, and connection terminal B is connected with the center-point of motor turning switch E, and IC does not have direct grounding leg.
When pole changer during just in the center, circuit cuts off the power supply fully, does not consume, when pole changer just turned to, during 3 pin output high potential, aerotron BG ended, BG conducting during the output active potential, steering indicating light DZ is bright, at this moment, because the direct coupling of IC and BG, both form electric current---voltage feedback, the result of balance is stabilized in about 2V the current potential between A, the B two ends, and the operating voltage on the steering indicating light DZ reduces about 2V, thereby has prolonged the service life of steering indicating light.
Spine pulse jamming in the automobile circuit is by capacitor C
1Absorb, reach the purpose of reliable operation and stabilized frequency.
