Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1 is as Fig. 1, and is shown in Figure 2, and relay is by often opening 105, two miniature relays 203 of button and 102, circuit board 200, shell body 100 formations that relevant components and parts (button, resistance, diode etc.) and bottom have plug 101.Miniature relay 203 is twin coil input relaies; Miniature relay 102 is unicoil output relays.These relays all are connected on the circuit board 200 with relevant components and parts; By the upper end of screw at the plug 101 of shell body 100 bottoms, the lower end of plug 101 then is positioned at the outside of shell body 100 bottoms to circuit board 200 by bent plate 204, uses for inserting socket.The visible Fig. 4 of the connection of plug 101 and distribution situation.Have in the outside of relay and often to drive button 105 by electric wire gang socket, two plugs 13,14 with the bottom of shell body 100 connect again, realize that circuit connects.
As shown in Figure 2, the electrical principle of present embodiment is such: relay comprises often leaves button 105, also comprises control circuit.Control circuit comprises by the input relay circuit, output relay circuit and board circuit.The input relay circuit is by input relay 203 (comprising coil L1 and L2), and normally-closed contact L1-1, L2-1 constitute, and link with power supply.Described output relay circuit is by output relay 102 (comprising coil L3), normally-closed contact L3-1, and normally opened contact L3-2 constitutes, and also links with power supply.Described board circuit is by unidirectional thyristor V4, diode V1, V2, V3, resistance R 1, R2, R3 constitutes, and with input relay circuit, the output relay circuit connection that links to each other.
When pressing when often driving button 105, power supply [+] is by the coil L1 in the input relay 203, normally-closed contact L3-1, L2-1 and power supply [-] connection, coil L1 adhesive, so that normally-closed contact L1-1 opens circuit.Simultaneously power supply [+] can be connected with power supply [-] by coil L2, normally-closed contact L1-1 in the input relay 203, resistance R 2, but on the one hand because the step-down of resistance R 2 makes the voltage of coil L2 gained be lower than pick-up voltage, makes the coil L2 can not adhesive; Opening circuit with normally-closed contact L1-1 on the other hand also makes the coil L2 can not adhesive; In addition, power supply [+] also can be by the coil L2 in the input relay 203, normally-closed contact L1-1, diode V3, V2, unidirectional thyristor V4 and power supply [-] are connected, but because unidirectional thyristor V4G end gate pole is subjected to the restriction of resistance R 3 and R2, can not trigger unidirectional thyristor V4 conducting and in loop here, the and then adhesive of coil L1, normally-closed contact L1-1 opens circuit, unidirectional thyristor V4 raises because of the G terminal voltage, electric current increases and the conducting that is triggered, but its trigger current is very little, can not make coil L2 adhesive.If between coil L1 and coil L2, add mechanical interlockedly, guarantee when making coil L1 adhesive that coil L2 can not adhesive; Unidirectional thyristor V4 triggering and conducting, power supply [+] is by input relay 203 coil L1 on the one hand, diode V1, unidirectional thyristor V4 and power supply [-] are connected, and power supply [+] is by output relay 102 coil L3, diode V2 on the other hand, unidirectional thyristor V4 and power supply [-] are connected, cause coil L3 adhesive, normally-closed contact L3-1 opens circuit, normally opened contact L3-2 path.Coil L3 is immediately by closed normally opened contact L3-2, and normally-closed contact L2-1 and power supply [-] are connected, and make coil L3 self-sustaining, and controlled electrical appliance is started working.When unclamping when often driving button 105, the coil L1 dead electricity of input relay 203 discharges, and input relay 203 quits work.
When pressing once more when often driving button 105, power supply [+] is by coil L2, normally-closed contact L1-1 in the input relay 203, diode V3, normally opened contact L3-2 and the normally-closed contact L2-1 and power supply [-] connection of closure, coil L2 adhesive in the input relay 203, normally-closed contact L2-1 opens circuit; Simultaneously the coil L1 in the input relay 203 is because the opening circuit of normally-closed contact L3-1, unidirectional thyristor V4 and diode V2 by and can not adhesive, along with opening circuit of normally-closed contact L2-1, output relay 102 dead electricity are discharged, and then electrical appliance are stopped.Normally-closed contact L3-1 and normally opened contact L3-2 are resetted, and coil L2 opens circuit because of normally-closed contact L2-1's, and the pressure drop of resistance R 2 makes the voltage at coil L2 place be higher than release voltage, so coil L2 still keeps adhesive.Unclamp once more when often driving button 105, coil L2 dead electricity discharges, and relay quits work.If press once more and often drive button 105, relay will operationalize once more, once more control operation is implemented in the start and stop of electrical appliance.
Embodiment 2 is as Fig. 3, and is shown in Figure 4, and relay is by often opening 105, two miniature relays 203 of button and 102, circuit board 200, shell body 100 formations that relevant components and parts (button, resistance, diode etc.) and bottom have plug 101.Miniature relay 203 is twin coil input relaies; Miniature relay 102 is unicoil output relays.These relays all are connected on the circuit board 200 with relevant components and parts; By the upper end of screw in the contact plug 101 of shell body 100 bottoms, the lower end of plug 101 then is positioned at the outside of shell body 100 bottoms to circuit board 200 by bent plate 204, uses for inserting socket.Have in the outside of relay and often to drive button 105 by electric wire gang socket, the plug 101 with the bottom of shell body 100 connects again, realizes that circuit connects.
The electric contact schematic diagram that distribution grid 106 is as shown in Figure 4 arranged on shell body 100 is convenient to terminal block and is used.
Window 104 is arranged on shell body 100, can observe the situation of relay inside, particularly the working condition of output relay 102.Output indicator 202 is arranged on shell body 100, can express the relay working condition, when the coil L3 of output relay 102 self-sustaining, controlled electrical appliance is started working, and output indicator 202 is luminous; And when the release of output relay 102 dead electricity, controlled electrical appliance quits work, and then output indicator 202 extinguishes.Also have self check button 201 on shell body 100, can be used as relay and use from detecting, also can be used as not, frequent operation uses.
This is an application example of this relay for embodiment 3.As shown in Figure 5.With the distribution grid 106 of the bottom plug 101 of the shell body 100 of relay as representative (Fig. 4).By electric contact 13,14 to relay input power supply, click and often drive button 105, enter relay by the signal of telecommunication of often driving button 105 from electric contact 7,11, relay produces action, subsequently by electric contact 4,12 come control contactor 301, and light indicator light 402, and then more powerful electrical appliance of control such as motor etc. are started working.Click once more and often drive button 105, relay quits work and electrical appliances such as contactor 301 and motor is stopped.Indicator light 402 extinguishes.The present embodiment repeat circuit adopts identical power supply with contactor 301.
This is the application example of this relay in dwelling house for embodiment 4.As shown in Figure 6.With the distribution grid 106 of the bottom plug 101 of the shell body 100 of relay as representative (Fig. 4).Often driving button 105 can have a plurality ofly, is separately positioned on front door, the doorway, study, doorways, bedroom etc. are imported power supply by electric contact 13,14 to relay, click any one and often drive button 105, enter relay by the signal of telecommunication of often driving button 105 from electric contact 7,11, relay produces action, subsequently by electric contact 4,12 come control setting in the parlor, and the illuminating lamp 401 on the passage (also can be more than) makes illuminating lamp 401 shinny.Click any one once more and often drive button 105, relay quits work, and illuminating lamp 401 has just extinguished.Adopt two kinds of power supplys in the present embodiment, illuminating lamp 401 adopts the power supply of 220V, and relay then adopts≤the safe voltage power supply of 36V.
