Description
Technical field
The utility model relates to a kind of power supply automatic change-over, more specifically relates to a kind of power supply automatic change-over of changing automatically between two different electrical power that is implemented in.
Background technology
Power supply automatic change-over before this is that the driver part of solenoid and mechanical retaining means are separately settled, and like this, the shared space of power supply automatic change-over is just bigger.
Summary of the invention
The utility model is a kind of improvement design to prior art, and a kind of driver part and incorporated power supply automatic change-over of mechanical retaining means with solenoid is provided.The utility model has been realized the purpose of product miniaturization.
For achieving the above object, the utility model has been taked following technical scheme:
The power supply automatic change-over comprises solenoid 1, moving iron core 2, static iron core 3, movable groove 5, spring frame 6; Solenoid 1 is located in the spring frame 6 with movable groove 5, and movable groove 5 is positioned at the top of solenoid 1 and links to each other with spring frame 6 by the spring frame hack lever 7 that is located at movable groove two ends; Moving iron core 2 is located at the top of static iron core 3, has the hole on the moving iron core 2, and links to each other with movable groove 5 by latch 4, and the diameter in hole is greater than the diameter of latch 4.
In technique scheme, the bottom of spring frame 6 is provided with spring 8.Below movable groove 5, be provided with a microswitch 10 of connecting with solenoid 1.
As improvement of the technical scheme, on movable groove 5, be provided with one can with the metal parts 9 of its interlock, the upper end of metal parts 9 is fixed on the movable groove 5 by fixture 11, the lower end is then between microswitch 10.
Another kind as technique scheme improves, and the utility model also is provided with moving contact 14 and fixed contact 15, and moving contact 14 is contained on the moving contact frame 12; The wheel shaft that is positioned at movable groove 5 central shafts directly links to each other with moving contact frame 12, and is connected to realization power supply output on the moving contact 14 by lead 13; The switching of power supply realizes with separating with the closure of moving contact 14 by the fixed contact 15 that the two-way mains side is settled separately.On moving contact frame 12, be equipped with and prevent to rebound screw 16.
Compared with prior art, the utility model becomes one driver part and mechanical holding member, thereby has realized miniaturization.Specifically be the solenoid that is set up in parallel 2 drivings, and place mechanical holding member, and effectively utilized the space in the outside of solenoid.In addition, electromagnetic core has designed the mechanism that can reduce stroke, has realized the solenoid miniaturization, the power consumption when having reduced action simultaneously.

Embodiment
Come the utility model is described further below in conjunction with Figure of description, but the utility model scope required for protection is not limited to the scope that execution mode is described.
Shown in Fig. 1-6: the magnetic force that the utility model is produced when utilizing solenoid 1 energising, moving iron core 2 is attracted by static iron core 3.The moving iron core 2 that has been attracted drives movable groove 5 setting in motions by latch 4.By on the moving iron core 2 greater than the hole of latch 4 diameters, realize that the suction-combining force is in the top in moving iron core 2 holes and the transmission of latch 4.
It is below 2/3 of stroke of movable groove 5 that its result makes the adhesive displacement (STROKE) of iron core 2.Because the space of moving iron core 2 and static iron core 3 is apart from shortening and under the repulsive force effect of spring 8, the magnetic force of required generation reduces during solenoid 1 action, thus the power consumption when having realized reducing solenoid 1 action.
In addition, when switching motion finishes, by the metal parts 9 that links with movable groove 5, microswitch 10 disjunctions of connecting with solenoid 1, the exciting current of solenoid 1 is by disjunction, the suction-combining force is disappeared, but under the repulsive force effect of spring 8, the state after switching motion finishes will keep always.
The wheel shaft that is positioned at movable groove 5 central shafts directly links to each other with moving contact frame 12, by lead 13, is connected to moving contact 14 and realizes power supply output.The switching of power supply realizes with separating with the closure of moving contact 14 by the fixed contact 15 that the two-way mains side is settled separately.Be equipped with on the moving contact frame 12 and prevent to rebound screw 16, in the time of can effectively having prevented excessive inrush current, because the moving contact that electromagnetic induction caused floats.
Compared with prior art, the utility model becomes one driver part and mechanical holding member, thereby has realized miniaturization.Specifically be the solenoid that is set up in parallel 2 drivings, and place mechanical holding member, and effectively utilized the space in the outside of solenoid.In addition, electromagnetic core has designed the mechanism that can reduce stroke, has realized the solenoid miniaturization, the power consumption when having reduced action simultaneously.
