Description
The present invention relates to a kind of improved pulling switch, particularly a kind of system, lower-cost multiduty pulling switch of being simple and easy to.Other electrical appliance power-off protection and the energy-saving safe of reaching that is suitable for illuminating lamp (particularly fluorescent lamp) electric fan, electric furnace.Can also use the function that it possessed in multiple electricity consumption control occasion.
Existing pulling switch, because inside mainly constitutes change over switch by backguy rope, cursor, garden post spring, ratchet, copper spring sheet, binding post etc., finish as change over switch by the backguy rop exercise external circuit on-off is controlled, the GX5-3 that produces of Chongqing plastic molding and processing plant for example, the 4A250V pulling switch is with regard to this function of tool.No matter be that the switch on-off all is that the operation backguy realizes.So under the situation that electricity is arranged, people are normally judged the change over switch state at that time of pulling switch the inside by the reflection of electrical appliance.Only can't judge on-off by the outward appearance of pulling switch.Have a power failure if take place suddenly, and people did not note the state of lamp or electrical appliance at that time, in public, more local especially true of illuminating lamps such as office, classroom, dormitory, the phenomenon that lamp or electrical appliance were worked always when that just took place to send a telegram here after the people walks probably again, having potential safety hazard on the one hand, also is the waste to electric power and illuminating lamp or consuming device on the other hand.
Needs are carried out the occasion that lights are concentrated control, locate as classroom, office block, army's barracks, dormitory, hospital ward etc.Generally take now regularly to draw master on off evening, the way that regularly close master on off morning manages.Because of a variety of causes, the pulling switch in many rooms does not still close after regularly drawing electric brake probably, and many lamps were not opened from bright again when therefore closed master on off morning in second day.Even the bright room electric fan of lamp then door but locked.And it also is disadvantageous to electrical network that the bigger load of this band closes master on off.
In addition, needs are carried out the occasion that lights are concentrated control, regularly draw evening generally will arrive second day morning behind the master on off and just close a floodgate and send electricity, this makes troubles with regard to giving in midnight the people of being badly in need of electricity consumption because of burst accident.
In sum, as seen using existing pulling switch is the effect that can't reach power-off protection, energy-saving safe.And carry out lights at needs and concentrate the occasion of control to use existing pulling switch also can't manage and solve concentrated control and concrete indivedual contradictions of using effectively.
Task of the present invention is to utilize the thyristor control technology that existing pulling switch is improved.The profile size of the pulling switch after the improvement is the same with existing pulling switch, can not change the wiring on the original wall fully, and utilizes the wood screw hole of original pulling switch directly to install, and good interchangeability is arranged.After loading onto this pulling switch, just can realize power-off protection, energy-saving safe to illuminating lamp, electrical appliance.Can also utilize the function that it possesses, use and carry out lights at needs and concentrate in the occasion of control, to accomplish effective management and to solve centralized management and concrete, indivedual contradictions of using.
Task of the present invention is that following mode is finished: this pulling switch is connected in series in AC power and the low-power electrical device circuit commonly used, in this pulling switch, the change over switch in keeping now existing pulling switch, other is provided with moving closing (often an opening) contact switch with the change over switch interlock.Every operation backguy rope once, in change over switch action, also momentary connection is once for the make contact switch.This pulling switch has two binding posts with outer circuit, and one of them binding post is connected to full-wave rectification bridge by change over switch and imports an end, and another binding post then directly is connected to the other end of full-wave rectification bridge input.The full-wave rectification bridge output plus terminal is got back to its negative terminal through thyristor anode and negative electrode, constitutes the main circuit of this pulling switch.Be connected to thyristor anode and control utmost point two ends after being in series by resistance and make contact switch, and capacitor is connected to the thyristor control utmost point and negative electrode two ends, with this pulling switch control circuit of common formation.Under power-off condition not, the change over switch connection makes outer circuit AC power become the direct voltage forward behind full-wave rectification bridge and is added on the thyristor two ends when operating this switch backguy rope, meanwhile control the utmost point because of sending a triggering signal to thyristor after the momentary connection of make contact switch, make the thyristor conducting, thereby this pulling switch is in conducting state.When operating this switch backguy rope once more change over switch is disconnected, though also momentary connection is once for the make contact switch, but because of main circuit is cut off, then this pulling switch is in closed condition, and as seen this pulling switch is as good as the break-make control action of external circuit and now existing pulling switch when not having a power failure.If after having a power failure for some reason again incoming call or people when drawing behind the master on off again reclosing; which kind of state no matter this pulling switch be in originally; cause make contact switch does not wherein move; thyristor control utmost point Triggerless thyristor remain off; make this pulling switch be in closed condition and cut off external circuit automatically, thereby played the effect of power-off protection, energy-saving safe.Have only this moment operation backguy rope that change over switch is connected, just can make this pulling switch be in conducting state under the also connection situation of make contact switch.(with the control lamp is example, if operation backguy rope once makes lamp bright, shows that then the change over switch in the pulling switch disconnects before sending a telegram here again, promptly turns off the light.If operation backguy rope secondary makes lamp bright, forgotten after then being equivalent to point out the user to have a power failure and turned off the light).Because this pulling switch has above power-off protection, energy-saving safe, or else the user must worry to have a power failure the back because of forgetting that closing electrical appliance leaves away and cause the danger and the generation of waste situation that may occur when sending a telegram here again.
This pulling switch can also apply to concentrate the occasion of control to lights (or electrical appliance) except above purposes.After regularly drawing master on off night, be equivalent to artificial power failure, institute's control interval lamp goes out.Estimate in the illumination occasion that the people has left away or dormitory in people are sleeping takes to overlap the master on off mode again and power.At this moment regardless of the occasion lamp switch original state that respectively throws light on, lamp all can be not bright.Because overlap master on off and be fully not on-load, therefore, handling safety does not have influence to electrical network.If indivedual rooms need electricity consumption really in midnight, also can make lamp bright by drag switch, so just can solve the problem that lights concentrate regulatory to exist effectively.
Below with reference to accompanying drawing invention is described in further detail.
Fig. 1 is an arrangements of elements schematic diagram on pulling switch base front surface shape of the present invention and its.
Fig. 2 is the basic circuit diagram of this pulling switch.Electronic component wherein is installed in the vallecular cavity of Fig. 1 base reverse side.
Shape, size and material therefor and existing GX5-3 with reference to the plastic feet 1 of this pulling switch of Fig. 1,4A, (Chongqing plastic molding and processing plant produces 250V type pulling switch, hereinafter to be referred as GX type switch) basic identical, only increased installation fixed contact 5, the perforation of the screw perforation of binding post 10 and binding post 8.The lid of this switch is also identical with existing GX type switch.In addition, the copper spring sheet of installing on the base 2, ratchet 3 and wheel are gone up part, binding post 4, switch backguy rope 6, garden post spring 7, axle 9, the planform of cursor 11 and layout, installation and existing GX type switch on base are identical.Therefore, existing GX type pulling switch interior conversion switch part and function have been kept in this pulling switch.But on base 1, set up a make contact switch etc. in addition, narrated the extension content below in conjunction with Fig. 1.
1, set up the fixed contact 5 of make contact switch.It is one and bends to 90 °, 0.8mm the left and right sides is thick, has certain flexible copper sheet, its one side (vertical with the drawing of Fig. 1) is pressed close to the side of the threading hole slot on the base 1, another side is fixed on the base 1 by screw 12 as shown in Figure 1, and another effect of screw 12 is to pass base front surface as the connecting line of fixed contact 5 with base reverse side circuit.
2, set up binding post 8, with binding post as make contact switch moving contact 13.It is to bend to 90 °, the copper sheet that the 0.3mm left and right sides is thick, and there is the hole, garden in its one side (face vertical with axle 9) central authorities, and rotating shaft 9 is passed from this hole, thereby this copper sheet is fixed on the base 1 by axle 9 and garden post spring 7.The axial break-through base 1 of its another side is inserted into its back side, as the terminals of base reverse side control circuit and make contact switch.
3, set up moving contact 13.It is that a screw rod stage casing has a perforation, the half knob screw of diameter of thread 3mm.Perforation is used for fixing the backguy rope of pulling switch.This screw passes the through wires hole on the existing GX type switch cursor 11, is fixed on the cursor 11 by nut 14.Therefore, when this switch backguy rope (as turn on light or turn off the light) of pulling, the moving contact 13 on the cursor 11 just rotates around axle 9 with cursor 11, till the copper sheet with fixed contact 5 contacts.So half knob screw 13 on fixed contact 5 and the cursor 11 has constituted quiet, the moving contact of make contact switch respectively.When the contact of the dynamic and static contact of make contact switch, the circuit that is installed in base 1 reverse side just passes through binding post 8, garden post spring 7(or axle 9), cursor 11, moving contact 13 is connected once with fixed contact 5.
4, set up binding post 10, be in fact for ease of with circuit on be connected the position that the binding post that joins with copper spring sheet 2 in the existing existing GX type switch is moved to Fig. 1 middle connecting terminal 10, the shape of binding post 10, size and mounting means and binding post 4 are basic identical.Outer circuit is imported an end by binding post 10 with the full-wave rectification bridge in being installed in this pulling switch back side circuit and is connected.
To mainly illustrate that in conjunction with Fig. 2 the circuit of this pulling switch constitutes the installation situation of circuit working principle and electric component below.
This pulling switch is connected with outer circuit with 10 by binding post 4, is connected to the on-off control circuit of supply and AC both ends of power after formation is in series with low-power electrical device (as daily illuminating lamp, electric fan etc.).Binding post 4 is named with Fig. 2 or Fig. 1 middle connecting terminal 4 and 2 through change over switch A42() be connected to an end of full-wave rectification bridge 15 inputs.Binding post 10 is connected to the other end of full-wave rectification bridge 15 inputs.The output plus terminal of full-wave rectification bridge 15 is got back to the output negative terminal of full-wave rectification bridge 15 through thyristor 16 sun levels and negative electrode, has constituted the main circuit of this pulling switch.Name with fixed contact 5 among Fig. 2 or Fig. 1 and binding post 8 by protective resistance 17 and make contact switch B58() be connected to the anode and the control utmost point two ends of thyristor 16 after being in series; capacitor 18 is connected to the control utmost point and the negative electrode two ends of thyristor 16, and the connected mode of above element just constitutes the control circuit of this pulling switch.Here need to illustrate 2 points; the first is provided with protective resistance 17 and specially the thyristor 16 control utmost points is shielded in circuit; because when if capacitor 18 branch road generation open circuit faults occurring; when opening this pulling switch; make thyristor 16 control utmost point moment overcurrent damage possibly; therefore; when selecting appropriate resistance can play the overcurrent protection effect; but under the normal situation of circuit; because of there being capacitor 18 to be attempted by between the control utmost point and negative electrode of thyristor 16, pressing and to suddenly change opening this pulling switch moment capacitor 18 ends.So we can say, being provided with this pulling switch realized giving of protective resistance 17 decided function aspects and do not played what effect.It two is because in the ordinary course of things, operation backguy rope only makes make contact switch B58 momentary connection once, therefore for guaranteeing that those electrical appliances (such as classes such as fluorescent lamp, electric fans) with retardation starting characteristic can normally start and move, will be according to the concrete condition of electrical appliance and thyristor 16 capacity, the capacitance of selecting capacitor 18 then can be selected more aforementioned much smaller condenser capacity to satisfying the demand for the electrical appliance (such as classes such as incandescent lamp, electric rangettes) of resistive load.
Be that example illustrates its operation principle with this pulling switch control illuminating lamp below:
Under the situation that electricity is being arranged, connect when operation backguy rope makes change over switch A42, this moment make contact switch B58 also momentary connection is once.Full-wave rectification bridge 15 output voltage forwards are added on thyristor 16 two ends, and simultaneously electric current is through protective resistance 17, and make contact switch B58 makes thyristor 16 conducting that is triggered to the thyristor control utmost point, and at this moment lamp is bright.Because of make contact switch B58 only be momentary connection once, so the extremely former circuits for triggering of thyristor 16 controls cut off, thyristor 16 desires blocking-up when thyristor 16 both end voltage zero passages, yet for and be connected in for the capacitor 18 between the thyristor control utmost point and negative electrode, when once giving thyristor 16 trigger impulses also to capacitor 18 instantaneous chargings, the voltage that exists between its control utmost point and negative electrode after thyristor 16 conductings is to the charging effect of capacitor 18 in addition, the magnitude of voltage that capacitor 18 two ends are kept be enough to make thyristor 16 terminal voltage zero passages next half-wave and after, because of its control utmost point still has trigger voltage to continue to keep conducting, promptly the bright state of lamp is constant.Disconnect when operation backguy rope makes change over switch A42, though this moment make contact switch B58 also momentary connection once, because of main circuit is cut off, lamp is then gone out by bright commentaries on classics.
If unexpected or artificial the power failure, thyristor 16 recovers blocking-up at this moment.When sending a telegram here again after if having a power failure, even change over switch A42 connects this moment, and thyristor 16 two ends have been applied in forward voltage, but because of not operating the backguy rope make contact switch B58 are moved again.So thyristor 16 still is not in blocking state because of the control utmost point has control voltage, can not switched on the principle of power-off protection that Here it is by the electrical appliance that this pulling switch is controlled yet.
If because of accidental cause causes full-wave rectification bridge 15 or thyristor 16 puncture shorts, this pulling switch also can be worked as a now existing pulling switch of only using as on-off circuit and be used (referring to Fig. 2).If being damaged, full-wave rectification bridge 15 or thyristor 16 open circuit, at this moment can be easily use (referring to Fig. 2 Fig. 1) being used as now existing pulling switch behind the mounting screw short circuit of binding post 10 and copper spring sheet 2, this adaptive capacity preferably is one of the characteristics of this pulling switch just.
From being simple and easy to system, reduce cost, the good aspects of interchangeability is considered, the electric component of this pulling switch is installed in the back side of base 1.Because of used electric component volume is little, quantity is few, and still there are some locus at the back side of base 1 in addition, and wiring is very convenient again, and does not influence the installation of this pulling switch.Can meet the demands through putting into practice fully.In addition, with during electric component is connected, can utilize the mounting screw afterbody crimping of binding post to draw the method for lead at binding post 2,5,10.
