In addition, as shown in Figure 5, described reactive torsion spring 5 comprises having the torsion spring 51 of bilateral symmetry setting and be connected in the flexible connecting rod between torsion spring 51 52 described in two, described in two, torsion spring 51 has respectively one for inserting the external part 53 in described gear gap 323, and described flexible connecting rod 52 is preferably and the identical material of described reactive torsion spring 5.During use, two symmetrically arranged described torsion springs 51 are placed in respectively between the described bending projection 121 of described armature 1 and the sidewall pivoting hole 34 of adjacent described armature bracket 3, the bilateral symmetry position of two symmetrical described torsion springs 51 that make described reactive torsion spring 5 in described bearing pin 4, described flexible connecting rod 52 is resisted against the described adhesive plate 12 of described armature 1 towards a side of described yoke 2 directions, and described adhesive plate 12 is subject to the side that described yoke 2 magnetic attractions rotate.So-called against refer to that described flexible connecting rod 52 keeps in touch with described adhesive plate 12 always, can certainly be by described flexible connecting rod 52 side corresponding to described adhesive plate 12 be coupled together, both are kept in touch, but described flexible connecting rod 52 is in described armature 1 turning course, and the reseting elasticity by described reactive torsion spring 5 can a side corresponding to described adhesive plate 12 keep in touch.
In the present embodiment, as shown in Figure 3, described through hole is preferably two that coordinate with described external part 53 positions of torsion spring described in two 51 respectively, and two through holes are all preferably square opening.Corresponding two described shift structures also all preferably have two described levers 322.
In the present embodiment, it is more reliable for described armature 1 is rotated on described armature bracket 3, as depicted in figs. 1 and 2, the symmetric position place that described armature 1 is formed with 121, two described bending projections 121 of two described bending projections along described adhesive plate 12 dual-side bendings respectively two of moulding is suitable for the described pin-and-hole 122 that described bearing pin 4 passes.Described armature bracket 3 two described in sidewall 31 in relevant position, form respectively for described bearing pin 4 through and described pivoting hole 34 that described bearing pin 4 is supported.During installation, described bearing pin 4 is first through two described pin-and-holes 122 in two described bending projections 121 of described armature 1, two described pin-and-holes are stretched out at the two ends of described bearing pin 4, then, by the two ends of described bearing pin 4 respectively through described armature bracket 3 two described in described pivoting hole 34 on sidewall 31, and the axle head that makes described bearing pin 4 clamps and be fixed in described pivoting hole 34, both can not relatively rotate.
Replaceable execution mode as embodiment 1, the difference of the present embodiment and embodiment mono-is: described positive stop lug boss 111 is embedded in described passage 321, and the lower limb of described passage 321 is described position-limited edge, when the disconnected lock of circuit breaker, described armature 1 under the reseting elasticity effect of described reactive torsion spring 5 to revolution, when described armature 1 returns back to by initial position before described yoke 2 adhesives, on described armature 1, the described positive stop lug boss 111 of moulding is resisted against the lower limb of described passage 321, and realization is spacing to described armature 1.
The present embodiment takes full advantage of described passage 321 structures, using the lower limb of described passage 321 as described position-limited edge, this kind takes shape in described shift structure and described position limiting structure the structure of one, process simple and convenient, when the many gears of the reseting elasticity of realizing described reactive torsion spring 5 regulate, simplified as much as possible the structure of the present embodiment electromagnetic release mechanism, and described shift structure and described position limiting structure all take shape in the production material that is conducive to save described armature bracket 3 on the described connecting wall 32 of described armature bracket 3, reduced production cost.
In the present embodiment, because the position of described position-limited edge is different from the position of position-limited edge in embodiment 1, therefore it is also different from the position of the positive stop lug boss 111 on push rod 11 that resets described in embodiment 1 to be molded over the position of the described positive stop lug boss 111 on described reset push rod 11, the described positive stop lug boss 111 of the present embodiment is with respect to the described positive stop lug boss 111 in embodiment 1, position more on the lower, so that described positive stop lug boss 111 is embedded in described passage 321, particularly, in use, when the disconnected lock of circuit breaker, armature 1 under the reseting elasticity effect of reactive torsion spring 5 to revolution, when described armature 1 returns back to by initial position before yoke 2 adhesives, on described armature 1, the described positive stop lug boss 111 of moulding is resisted against the lower limb of described passage 321 just, the location of realization to described armature 1.
Obviously, above-described embodiment is only for example is clearly described, and the not restriction to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And the apparent variation of being extended out thus or change are still among protection range of the present utility model.
