Description

Solenoid Automatic Regulation Control device

Technical field

The utility model relates to the Electromagnetic Control field, particularly a kind of solenoid Automatic Regulation Control device.

Background technology

The electromagnetic force that is produced when switching on solenoid in the prior art promote iron core have as the product of actuator many, as A.C. contactor, electromagnet, electromagnetically operated valve etc.The ubiquitous shortcoming of these products is that power consumption is big, the coil temperature rise height, and noise is big.For addressing the above problem, the applicant has designed a kind of automatic voltage-regulating and power-saving module for electromagnetic valve at ZL99104585.8 in 99209250.7 patents.Effect, the effect of the electromagnetically operated valve sensing controler that this patented product and California, USA one company are designed are the same, and certain energy-saving and cost-reducing effect is arranged, and can reduce coil temperature rise.Problem is that circuit more complicated, the volume of these products is big, cost is high, be difficult to be directly installed in the electric iron coil or plug in, thereby limited its application.

Summary of the invention

Task of the present utility model is a kind of power consumption of design and the solenoid temperature rise is low, energy-conservation and noise is little, and especially volume is little of the micro electromagnetic coil Automatic Regulation Control device that can be loaded in solenoid or the plug.

Technical scheme is as follows:

Solenoid Automatic Regulation Control device comprises the power input and the power output end of interchange, is connected with the electronic switching circuit that a pair of triggers the high and low voltage of time-delay output between power input and power output end.

The core devices of described electronic switching circuit is the two flip chips of 6267 type time variant voltage output; First utmost point of described power input joins with the power end of two flip chips after rectifier half-wave or full-wave rectification; The one total head pulse-triggered branch road that is made of resistance and capacitances in series is arranged between the power end of flip chip and total head trigger end; The output of flip chip extremely links to each other with first of described power output end; Second utmost point of described power input directly links to each other with power output end; Cross-over connection has a reverse fly-wheel diode between first and second utmost point the two poles of the earth of power output end; Cross-over connection has a step-down that is made of resistance and electric capacity to trigger branch road between the output of the power end of flip chip and flip chip, and the tie point of this resistance and electric capacity links to each other with the step-down pulse-triggered end of flip chip.

Described two triggering time-delay electronic pressure switching circuit is packaged in one and has in the cylinder blanket of external screw, and its power input and power output end are drawn outside it by lead.

According to such scheme, when the utility model is used to control electromagnetic actuator, can make electromagnetic core overcome its adhesive to the big electric current power supply of solenoid total head when energising just with the gap greatly of solenoid; After its stable (time-delay) adhesive, first triggers electric capacity can not discharge owing to the non-return effect of rectifier diode, thereby make output in time turn-off, two flip chips of second trigger circuit triggers and export the low-voltage (1/3-1/5 of total head) that is enough to keep the iron core attracting state, little electric current meanwhile, thus solenoid is no longer generated heat.Owing to adopted integrated level height, two flip chips (production of U.S. VTD company) of 6267 power output types that volume is little, the utility model has adopted peripheral circuit simple in structure, ingenious, that element is few in addition, thereby make volume of the present utility model very little (outer warp is less than 15mm, long 13mm), can directly be encapsulated in electromagnet, A.C. contactor, electromagnetically operated valve, even in its joint.The utility model economize on electricity can reach 80%, and controlled solenoid does not have temperature rise, with low cost, good reliability substantially, has brilliant market developing prospect.

Embodiment

Micro electromagnetic coil Automatic Regulation Control device is connected with the electronic switching circuit 11 that a pair of triggers the high and low voltage of time-delay output between its power input and power output end.The core devices of this electronic switching circuit is the two flip chips of 6267 type time variant voltage (two kinds of voltage controlled) electronic power output; First utmost point 7 of power input joins with the power end 6 of two flip chips after rectifier D1 halfwave rectifier; The total head pulse-triggered branch road that between the power end 6 of flip chip and total head trigger end 2, constitutes by resistance R 1 and capacitor C 1 series connection; The output 4 of flip chip links to each other with first utmost point 9 of power output end; Second utmost point 8 of power input directly links to each other with power output end 10; Cross-over connection has a reverse sustained diode 2 between first and second

utmost point

9,10 of power output end; Cross-over connection has a step-down that is made of adjustable resistance R2 and capacitor C 2 to trigger branch road between the output 4 of the power end 6 of flip chip and flip chip, and the tie point of this resistance R 2 and capacitor C 2 links to each other with the step-down pulse-triggered end 3 of flip chip.Change the value of resistance R 1, resistance R 2, can change delay time.Between the discharge end 1 of the tie point of the resistance R 1 of total head pulsed triggering circuit and capacitor C 1 and described flip chip, also be provided with a discharge resistance R2.

Whole two triggering time-delay electronic pressure switching circuit is packaged in one and has in the cylinder blanket (12) of external screw, and its power input and power output end are drawn outside it by lead.

Operation principle of the present utility model is:

When circuit was just switched on, under the effect of total head circuits for triggering, it was to solenoid output AC full voltage, thereby the load iron wicking is closed; After the iron core adhesive, the time-delay of the electric capacity of total head circuits for triggering charges to and to a certain degree then makes two flip chips automatically shut down output, and meanwhile, step-down triggers branch road then makes the output of two flip chips be converted to the 1/3-1/5 of total head, and makes iron core keep attracting state.Thus, realized the total head/step-down conversion of power supply output.The effect of discharge resistance R2 is to cut off the power supply the not time spent when the utility model, makes total head trigger capacitor C 2 discharges of branch road, thereby guarantees can reliably trigger when it is switched on once more.
