Embodiment
Embodiment 1 (Fig. 1-Fig. 4)
This example is the temperature protective device of remote control socket.
Circuit diagram referring to Fig. 1 remote control socket; J1, J2 end are 220 volts of ac power input ends; The bridge rectifier that J1, J2 form through D1-D4, voltage-stabiliser tube Z1, capacitor C 9, C2 and voltage-stabiliser tube Z2, capacitor C 4, C3, resistance R 6 respectively composition+24V and+the 5V DC power-supply circuit.
Zero line input J2 is electrically connected with remote control socket zero line output J3, and live wire input J1 is electrically connected with the live wire output J4 of remote control socket through the switch contact of relay R L1, by the switch of relay R L1 control remote control socket output circuit.
Remote control circuit is:
The remote-control receiving circuit that antenna L2 and peripheral circuit are formed is used to receive the remote control switch signal;
U1 (H8006) forms decoding circuit with peripheral circuit, and U2 (24C02) is a memory circuit, and remote-control receiving circuit output RF_DATAIN is connected with 7 pin of decoding circuit, and output control terminal 5 pin of decoding circuit are connected with the base stage of switch control valve Q1.
Relay R L1 coil tandem the collector electrode of switching tube Q1 and+24 volts of power supplys between, by the break-make on Q1 control relay coil power supply road road, the contact of relay R L1 is connected in the loop of remote control socket live wire output J4.
This routine temperature protective device is:
In relay 2 (RL1 in the circuit diagram) coil power supply loop, be in series with temperature safety tube 3 (F1 in the circuit diagram), it is K18 that this example adopts the model of temperature safety tube 3;
Referring to Fig. 2; This routine relay 2 is contained on the printed circuit board (PCB) 1; Two contact pins 22 of relay are welded to connect (Fig. 3) with the contact pad 6,7 of circuit board respectively; Two contact pads are electrically connected with live wire input J1 and live wire output J4 respectively, and two contacts of relay are connected with socket live wire output services loop through the contact pad.
