Description
Technical field
The utility model relates to a kind of relay, relates in particular to a kind of minisize electromagnetic relay that is applied to drive in the electronic circuit.
Background technology
The minisize electromagnetic relay is with its reliable in action, with low cost being used widely in electronic circuit; Relay has incomparable advantage as driving element; Minisize electromagnetic relay isolation voltage reaches 5000V, and drive current can reach tens of amperes, but relay is again the bigger components and parts of power consumption; Particularly in the circuit with multichannel driving, how reducing power consumption is the key of research.According to the electromagnetic type relay characteristic; Can use triode, resistance and electric capacity to form energy saving driving circuit fully; The operation voltage of relay generally rated voltage 75% to 120% between, and after its reliable adhesive, keep pick-up voltage to have only 30% to 50% of rated voltage; The utility model utilizes this characteristic of relay exactly, reaches energy-conservation 50% purpose.
The utility model content
The purpose of the utility model is bigger to minisize electromagnetic relay adhesive power consumption, proposes a kind of energy-conservation driving minisize electromagnetic relay circuit, makes it energy-saving effect and reaches more than 50%.
The utility model adopts following technical scheme:
A kind of direct current minisize electromagnetic relay energy saving driving circuit; Comprise that positive supply VCC connects current-limiting resistance R1, resistance R 1 connects capacitor C 1, capacitor C 1 connection relay J 1, diode D1 and relay parallel connection; Relay is connected with triode BG1, and triode BG1 and resistance R 3, R2 form control circuit.Control signal IN connects resistance R 3, and resistance R 3 connects triode BG1, and triode BG1 one end connects power cathode VSS.
The beneficial effect of the utility model is:
Positive supply VCC gives capacitor C 1 charging through resistance R 1, and triode BG1 conducting moment relay voltage is identical with power supply VCC voltage, the relay adhesive; C1 voltage descends then; Resistance R 1 and relay series connection, because resistance series connection metering function, electric current reduces significantly; And relay can keep attracting state, thereby realizes energy-saving effect.Can reduce the midget relay power consumption significantly.
Description of drawings
Fig. 1 is that circuit is formed schematic diagram.
Embodiment
According to embodiment the utility model is done further explain below.
As shown in Figure 1, positive supply VCC connects current-limiting resistance R1, resistance R 1 connects capacitor C 1, capacitor C 1 connection relay J 1, diode D1 and relay parallel connection, and relay is connected with triode BG1, and triode BG1 and resistance R 3, R2 form control circuit.Control signal IN connects R3, and R3 connects triode BG1, and triode BG1 one end connects power cathode VSS; Positive supply VCC gives capacitor C 1 charging through resistance R 1, and triode BG1 conducting moment relay voltage is identical with power supply VCC voltage, the relay adhesive; C1 voltage descends then, and resistance R 1 and relay series connection are because resistance series connection metering function; Electric current reduces significantly, and relay can keep attracting state, thereby realizes energy-saving effect.Can reduce the midget relay power consumption significantly.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the execution mode of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation and changes.Here can't give exhaustive to all execution modes.Conspicuous variation that every technical scheme that belongs to the utility model is amplified out or change still are in the row of the protection range of the utility model.
