Description
Technical field
The utility model provides the relay contactor that appliance field is used for connecting and disconnecting of the circuit, specifically a kind of electromagnetism, the interactive relay contactor of permanent magnetism.
Background technology
Before the utility model proposes, the structure of relay and A.C. contactor is: be provided with iron core on solenoid, be provided with armature in the iron core upper end, armature is connected with contact.The magnetic field that produces by solenoid energising back drives armature movement, thereby drives being in contact with one another or breaking away from of dynamic and static contact, realizes connecting and disconnecting of the circuit.This electromagnetic type relay and A.C. contactor solenoid when work is in "on" position always, not only power consumption is big, and solenoid scaling loss or aging phenomenon take place easily, and also being subjected to the frequent contact of effect contact or the disconnection of curtage easily, influence is normally used.
Summary of the invention
In order to overcome the shortcoming of existing relay or A.C. contactor, the utility model proposes a kind of electromagnetism, the interactive relay contactor of permanent magnetism.This kind contactor can realize that electromagnetism, the interactive contact that drives of permanent magnetism move.
The technical scheme in the invention for solving the technical problem is: be connected with loam cake by connecting portion on base, in loam cake, movable slider is installed by spring guide pillar, the movable slider upper end is connected with contact, in the movable slider lower end permanent magnet is installed, in base inside solenoid is installed, controller is installed in solenoid, in the controller upper end suction iron is installed, on suction iron, be provided with and inhale the iron film, it is corresponding with the permanent magnet position to inhale the iron installation site, be respectively equipped with binding post at the chassis outer side two ends, pulse generator is housed in controller and is connected with capacitor by lead, be provided with the controller binding post on controller, the lead by pulse generator and capacitor is connected with solenoid and constitutes the work loop.
Good effect: owing to be connected with permanent magnet on the movable slider of the present utility model, and corresponding with it base inner upper end is connected with suction iron, and realize electromagnetism and permanent magnetism interaction by controller, make on the slide block permanent magnet with inhale iron and be in adhesive or repulsion state, thereby drive being in contact with one another or disconnecting of contact.Under the state of adhesive, contact or disconnection by the adhesive maintenance contact between permanent magnet and the suction iron, do not have electric current to pass through in the solenoid this moment, thereby the power consumption of saving solenoid, reduced noise simultaneously, can also prevent that contact is subjected to the influence of curtage and the phenomenon of the frequent break-make that produces takes place.The suitable appliance field of the utility model is used the occasion of relay and A.C. contactor and is used.
Description of drawings
Fig. 1 is the utility model structure chart
Fig. 2 is the utility model circuit connection diagram
Among the figure, 1. base, 2. loam cake, 3. connecting portion, 4. movable slider, 5. spring guide pillar, 6. solenoid is 7. inhaled iron, 8. inhales the iron film, 9. controller, 10. permanent magnet, 11. contacts, 12. binding posts, 13. controller connector lugs, 14. pulse generators, 15. electric capacity.
Embodiment
According to illustrated in figures 1 and 2, on base 1, be connected with loam cake 2 by connecting portion 3, in loam cake, movable slider 4 is installed by spring guide pillar 5, the movable slider upper end is connected with contact 11, in the movable slider lower end permanent magnet 10 is installed, in base inside solenoid 6 is installed, controller 9 is installed in solenoid, in the controller upper end suction iron 7 is installed, on suction iron, be provided with and inhale iron film 8, it is corresponding with the permanent magnet position to inhale the iron installation site, be respectively equipped with binding post 12 at the chassis outer side two ends, pulse generator 14 is housed in controller 9 and is connected with capacitor 15 by lead, be provided with controller binding post 13 on controller, the lead by pulse generator and capacitor is connected with solenoid 6 and constitutes the work loop.
The course of work of the present utility model is: the binding post on being located at base is connected with power line and when having electric current to pass through, electric current is by controller and make pulse generator work, make the capacitor charging simultaneously, behind sufficient charge in the capacitor, connect solenoid, produce magnetic field, act on and inhale on the iron, be subjected to the effect that the magnetic field same sex is repelled each other, there is a natural attraction between the sexes, attraction is installed in the permanent magnet on the movable slider, makes it to contact with inhaling iron phase, moves down thereby drive movable slider, the action of drive contact realizes being switched on or switched off by the circuit of contact.This moment, spring guide pillar was in compressive state.And capacitor is in saturation condition, stops electric current motion in the solenoid, thus consumed power not, and electric current is just kept the operating state of controller.When binding post did not have electric current to pass through, capacitor discharged in solenoid, made solenoid produce the opposing magnetic field, promote permanent magnet to inhale the direction motion that iron deviates from, thereby drive the contact contact or disconnect, realize being switched on or switched off by the circuit of contact.
