Abstract
The utility model relates to an instantaeous power consumption bistable electromagnetic relay, which is compoed of a common electromagnetic relay. The utility model is characterized in that a piece of permanent magnet is added between an iron core and a yoke; a relay coil is connected with a power supply through a current transmitting and controlling circuit. The utility model has the advantages of simple structure, low cost and convenient maintenance; an old type monostable relay can be conveniently reformed into the bistable relay.
Description
The utility model relates to a kind of relay.
Because the coil of conventional electromagnetic relay must be switched on for a long time, could keep the closure state of normally opened contact, and power consumption equipment is kept operation, therefore, can consume a large amount of electric energy.Though electrical type relay power controlling is little, also exist following shortcoming: self still have power consumption, complex structure, cost an arm and a leg and fragile etc.
The purpose of this utility model is to provide a kind of instantaneous power consumption bistable electro magnetic relay.
The utility model is made up of armature, iron core, coil and the iron yoke of common electrical magnetic relay, it is characterized in that: increase a permanent magnet between iron core and iron yoke, relay coil is connected with power supply by the current conversion control circuit.
Aforesaid current conversion control circuit can be positive and negative pulse generator.
Aforesaid current conversion control circuit can be one group of switching circuit.
The utility model can make various common electrical magnetic relaies into the bistable electro magnetic relay, it only needs a pulse forward or backwards to control the adhesive and the release of armature, therefore, consumed power seldom, have simple in structure, cheap, be convenient to keep in repair and transform the characteristics that old-fashioned monostable relay becomes bistable relay easily.
The drawing explanation:
Accompanying drawing is instantaneous power consumption bistable electro magnetic relay embodiment described in the utility model.
The utility model concrete structure and operation principle are seen accompanying drawing: (1) is armature among the figure, and (2) are iron cores, and (3) are coils, and (4) are permanent magnets, and (5) are the iron yokes, and (6) are the current conversion control switchs, and (7) are DC power supply.Coil (3) is during by a certain directional current, and the magnetic direction that it produced is just in time identical or opposite with the magnetic direction of permanent magnet (4), and when identical, the magnetic field that coil (3) produces and the magnetic field of permanent magnet are superimposed, and armature is by adhesive, the connection normally opened contact.When opposite, the magnetic field that coil (3) produces is opposite with the magnetic field of permanent magnet, and magnetic force is cancelled out each other, and armature is discharged, and opens normally opened contact.After armature is by adhesive, be to keep its attracting state by permanent magnet.The utility model also can be made up of other current converter circuit, as: 555 time-base circuits and operational amplifier etc. can produce the digital circuit of positive and negative pulse.The utility model can adopt electric capacity accumulation of energy form control relay, reaches with the purpose of small power supply power control than high power relay.
Claims (2)
1. instantaneous power consumption bistable electro magnetic relay, it is made up of armature, iron core, coil and the iron yoke of common electrical magnetic relay, it is characterized in that: increase a permanent magnet between iron core and iron yoke, relay coil is connected with power supply by the current conversion control circuit.
2. a kind of instantaneous power consumption bistable electro magnetic relay as claimed in claim 1 is characterized in that: the current conversion control circuit can be positive and negative pulse generator or one group of switching circuit.
