Description
Technical field
The utility model is related to insert row, and in particular to a kind of adjustable intermittent formula is powered insert row.
Background technology
It is required for setting the lamp flashed now with many occasions such as market, shop and needing the intensive traffic section avoided
Light is attracted much attention, and traditional insert row can only provide 220 volts of alternating currents of specified 50 hertz, when the access of general electric light is inserted
After row, electric light is to continue illuminating state visually observing lower, can not flash it.And the another kind of electric light that can be flashed is general
It is required for controlling it to flash by installing the single-chip microcomputer of programmed additional, production and processing is complicated, cost is higher, and typically can not
The frequency for controlling it to flash.
The content of the invention
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide a kind of intermittent power supply,
And the adjustable intermittent formula of the frequency of intermittent power supply can be adjusted power insert row.
Therefore, the utility model is realized using following scheme：
Adjustable intermittent formula is powered insert row, including insert row housing and external plug, and the surface of insert row housing is inserted provided with power supply
Hole, it is characterised in that：The inside of insert row housing is provided with the electric circuit of control, and the electric circuit of control includes controllable silicon, 3rd resistor and mutually
The feeder ear connection of the rectifier bridge stack of series connection, first resistor, adjustable resistance, second resistance, rectifier bridge stack and power supply, controllable silicon is simultaneously
It is associated in the positive and negative end of rectifier bridge stack, the two ends of adjustable resistance and second resistance are parallel with the first electric capacity, the two of second resistance
End is parallel with the second electric capacity, and 3rd resistor one end is connected to controllable silicon, and the other end is connected between adjustable resistance and second resistance.
The resistance adjustment knob of adjustable resistance is located at the surface of insert row housing.
Using above-mentioned technical proposal, by setting the electric circuit of control inside insert row, the intermittent power supply of insert row is realized, and
Adjustable resistance is set, the frequency of its intermittent power supply can be adjusted, circuit design very simple is easy to production and processing.Using above-mentioned
Technical scheme replaces tradition to control the mode that the electric light flickers using single-chip microcomputer so that general electric light i.e. can be with after access insert row
Flicker is realized, and its flicker frequency can be adjusted.
Brief description of the drawings
The utility model has drawings described below：
Fig. 1 is shape assumption diagram of the present utility model；
Fig. 2 is the electric circuit diagram of control of the present utility model.
Embodiment
Insert row, including insert row housing 1 and external plug as illustrated, adjustable intermittent formula disclosed in the utility model is powered
3, the surface of insert row housing 1 is provided with supply hub 2 and resistance adjustment knob 4, and the inside of insert row housing is provided with the electric circuit of control, control electricity
Circuit includes controllable silicon SCR, 3rd resistor R3 and the rectifier bridge stack 5 being mutually in series, first resistor R1, adjustable resistance W, second
Resistance R2, rectifier bridge stack 5 is connected with the feeder ear of power supply, and controllable silicon SCR is connected in parallel on the positive and negative end of rectifier bridge stack 5, resistance
Resistance of the adjusting knob 4 for adjusting control adjustable resistance W, adjustable resistance W and second resistance R2 two ends are parallel with the first electricity
Hold C1, second resistance R2 two ends are parallel with the second electric capacity C2, and second electric capacity C2 one end and adjustable resistance W and second resistance R2
Between node a connections, 3rd resistor R3 one end is connected with controllable silicon SCR, and the other end is connected with node a.
The electric circuit theory of control of the present utility model is：After 220 volts of alternating currents first flow through the rectification of rectifier bridge stack 5, electric current
From the outflow of the positive pole of rectifier bridge stack 5 flow through first resistor R1, adjustable resistance W, second resistance R2 successively after from rectifier bridge stack 5
Negative pole is flowed out, and while electric current flows through second resistance R2, the second electric capacity C2 for being connected in parallel on second resistance R2 two ends is started to charge up,
Start electric discharge after the second electric capacity C2 is full of, now controllable silicon SCR is influenceed and turned on by the second electric capacity C2 electric discharges so that rectification
The both positive and negative polarity short circuit of bridge heap 5, insert row is stopped power supply, and accesses the lights of insert row, and after the second electric capacity C2 electric discharges terminate, can
Control silicon SCR is again off, and now electric current can flow through first resistor R1, adjustable resistance successively from the positive pole outflow of rectifier bridge stack 5 again
Flowed out after W, second resistance R2 from the negative pole of rectifier bridge stack 5, insert row is powered again, the electric light of access insert row is lighted, and is worked as afterwards
Second electric capacity C2 starts after electric discharge, and electric light extinguishes again, so moves in circles, and realizes the flicker of electric light.In addition, passing through resistance
The adjustment adjustable resistance of adjusting knob 4 W resistance, and then change the second electric capacity C2 charge rate, the frequency that the electric light flickers is adjusted,
When adjusting knob 4 moves clockwise to bottom, insert row provides 220 volts of alternating current, can be used as common insert row, work as knob
After rotating counterclockwise, rotational angle is bigger, and the frequency that the electric light flickers is bigger.
