The utility model is characterized in that grooves from top to bottom are symmetrically opened on the outer periphery of the T-shaped armature iron, and the number of the groove is at least two. A groove which is opened on the T-shaped armature iron increases the circulation passage of air, effectively discharges or supplements air in the T-shaped armature iron, and reduces the moving resistance of the T-shaped armature iron, and the bistable actuating mechanism is provided with the tripping spring, thereby guaranteeing an actuating bar to be in a stable and reliable work state. And therefore, the utility model has the advantages of reasonable structure, reliable performance and excellent energy-saving effect.
Description
Technical field
The utility model relates to a kind of contactor, especially relates to a kind of architecture advances of permanent magnetism type contactor operation device, belongs to the appliance switch technical field.
Background technology
Contactor is a kind of widely used electric controling switch device, and traditional common AC and DC contactor mainly is made up of moving contact rack, moving armature, static gag bit and coil etc.Coil must be switched on for a long time during this type of contactor work, not only waste electric energy, and noise is big, useful life short.In addition, the permanent magnetism type contactor that gets up of development in recent years mainly by the outer yoke that constitutes magnetic loop, be installed in wherein coil, be inserted in armature in the coil hole and permanent magnet etc. and form.Though this contactor has economize on electricity, noiseless, magnetic usefulness utilance than advantages such as height, but the gap between its armature and coil and the inner yoke is very little, when armature moves down in coil and inner yoke, because the air between armature top and the outer yoke in the space can't be discharged, air is compressed, and has increased the resistance that armature moves downward, and causes the exciting current that must improve coil, increase electromagnetic force, could guarantee that armature moves into place; When armature moves upward, because the air between armature top and the outer yoke in the space can not get replenishing, cause parital vacuum, stop armature to move upward, need to improve exciting current and could guarantee that the armature disjunction puts in place, stability, reliability when causing using are not ideal enough, also waste electric energy simultaneously.
Summary of the invention
Be to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of electric energy of not only saving, and can reduce the armature motion resistance, guarantees the permanent magnetism type contactor bistable state operating mechanism of reliable and stable work.
To achieve these goals, the utility model is to realize by following technical scheme:
A kind of permanent magnetism type contactor bistable state operating mechanism, comprise the outer yoke that constitutes magnetic loop, be installed in wherein coil, be inserted in T type armature and permanent magnet in the coil hole, between coil upper surface and T type armature lower surface, tripping spring is housed, described permanent magnet is fixed on the bottom surface of outer yoke, the boss shape that become to stretch into coil, can contact with T type armature bottom, the neighboring that it is characterized in that described T type armature has groove from top to bottom symmetrically.
Aforesaid permanent magnetism type contactor bistable state operating mechanism is characterized in that described groove is at least 2.
Aforesaid permanent magnetism type contactor bistable state operating mechanism is characterized in that described outer yoke is constituted by a solid connection with each other by upper magnet yoke, side yoke and lower yoke.
Aforesaid permanent magnetism type contactor bistable state operating mechanism is characterized in that described tripping spring is the turriform spring.
The beneficial effects of the utility model are: the utility model is by slotting on T type armature, increased the circulation path of air, can discharge timely and effectively or the air of additional T type armature bottom, reduce the moving resistance of T type armature, and be equipped with tripping spring, thereby guarantee that the actuating bar is in reliable and stable operating state.Therefore, the utlity model has the advantage of rational in infrastructure, dependable performance, good energy-conserving effect.
Description of drawings
Fig. 1 is a permanent magnetism type contactor bistable state operating mechanism structure cross-sectional schematic of the present utility model;
Fig. 2 is the upward view of the T type armature among Fig. 1;
Fig. 3 is the cutaway view of the T type armature among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a permanent magnetism type contactor bistable state operating mechanism structure cross-sectional schematic of the present utility model; Fig. 2 is the upward view of the T type armature among Fig. 1; Fig. 3 is the cutaway view of the T type armature among Fig. 1.
As shown in the figure, permanent magnetism type contactor bistable state operating mechanism of the present utility model, comprise upper magnet yoke 3, side yoke 5, lower yoke 6, coil 4, T type armature 2, permanent magnet 7 and tripping spring 1 etc., upper magnet yoke 3, side yoke 5 and lower yoke 6 are connected mutually, constitute the outer yoke that forms magnetic loop, coil 4 is installed in the outer yoke, T type armature 2 is inserted in the coil 4, tripping spring 1 is the turriform spring, be sleeved on the neck root position of T type armature 2, its two ends are connected with the downside on T type armature 2 tops and the upper surface of coil 4 respectively.Permanent magnet 7 is suitable with the bottom of T type armature 2, and is fixed on the lower yoke 6, becomes to stretch into the boss shape of coil 4.The neighboring of T type armature 2 has at least 2 grooves 8 (shown in the figure be 2, but be not limited thereto) from top to bottom symmetrically.
Below explanation the utility model is realized disjunction and two conversion of operation state processes of adhesive.
From attracting state to the disjunction state: add the direct impulse electric current to coil 4, making the polarity of the magnetic field of T type armature 2 lower ends is the N utmost point, since with the contacted permanent magnet 7 in its lower end on polarity of the magnetic field also be the N utmost point, therefore both repel mutually, and T type armature 2 is subjected to magnetic force and moved upward by the thrust of tripping spring 1.This moment, the moving contact rack of contactor was in the disjunction position; After pulse current disappeared, 2 supports by tripping spring 1 of T type armature made the moving contact rack of contactor be stabilized in the disjunction position.In this process, form parital vacuum between T type armature 2 bottoms and the lower yoke 6, extraneous air adds between T type armature 2 and the lower yoke 6 by groove 8, and preventing increases the disjunction resistance because of vacuum.
From the disjunction state to attracting state: add the reverse impulse electric current to coil 4, making the polarity of the magnetic field of T type armature 2 lower ends is the S utmost point, because the permanent magnet 7 upper end magnetic poles in its lower end are the N utmost point, therefore both attract each other, the thrust that T type armature 2 is subjected to magneticaction also to overcome separating brake bullet Huang 1 simultaneously moves downward, contact with permanent magnet 7 upper surfaces until the bottom, the air between T type armature 2 bottoms and the lower yoke 6 is discharged by groove 8, and air can not increase the connection resistance because of being compressed.This moment, the moving contact rack of contactor was in the attracted position; The S utmost point by the N utmost point → T type armature 2 → upper magnet yoke 3 → side yoke 5 → lower yoke 6 one permanent magnets 7 of permanent magnet 7 has constituted a closed magnetic circuit, even after pulse current disappears, also can overcome the active force of tripping spring 1, keeps stable attracting state.
The utility model provides the circulation path of air owing to slot 8 on T type armature 2, has effectively reduced the moving resistance of T type armature 2, guarantees the electric switch reliable operation, and stable and reliable working performance has remarkable energy saving effect.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection range of the present utility model.
