Preferably, described armature location structure also comprises hook shell fragment, and described hook shell fragment is installed on electromagnetism and continuesOn the pedestal of electrical equipment, one end of described hook shell fragment upwards extends to form elastic portion, and described elastic portion flexiblyPress on the outside of described movable iron, make the lower end of described movable iron be close proximity to the lower end of described iron coreEnd face; Described movable iron and the described iron core heart are pressed close to the magnetic effect of the electromagnet that can strengthen, thereby make it moreThe easily upper end of movable iron described in adhesive.

Particularly, the middle part of described hook shell fragment forms the recess that holds described pressure section, and described recess can be protectedDemonstrate,prove reliable that described pressure section coordinates with described press keeping section, thereby it is stable that described movable iron is swung.

Particularly, the other end horizontal-extending of described hook shell fragment forms fixed part, described in described iron core pressure holdingFixed part is on described pedestal. By utilizing described fixed part, can make described in described hook shell fragment is fixed onOn pedestal, thereby ensure that the elasticity of described elastic portion is effective.

Preferably, described recess is inverted trapezoidal structure.

Preferably, the lower surface of described pressure section is to curved between outside, in case spline interferes when moving.

Detailed description of the invention

For the effect that describes technology contents of the present utility model, structural feature in detail, realizes, below in conjunction withEmbodiment also coordinates accompanying drawing to be explained in detail.

As shown in Figure 1 and Figure 2, the utility model electromagnetic relay 100 comprise pedestal 1, electromagnet coil 2,Iron core 3, movable iron 4, moving part 5, static terminal 6 and moved end 7, described iron core 3 structure that takes the shape of the letter U,Described iron core 3 is vertical and is installed on regularly described pedestal 1; Described electromagnet coil 2 is wound in described ironOutside core 3; Described movable iron 4 is vertical structure, and vertically arrange and lower end be movably arranged in instituteState on pedestal 1, the side of described movable iron 4 is in the face of the end face of described iron core 3, described movable iron 4Upper end hold and be connected with described moving part 5, the other end of described moving part 5 and described moved end 7Upper end connects, and the lower end of described moved end son 7 and static terminal 6 is installed on respectively described pedestal 1 regularly, described inStatic terminal 6 is between described moved end son 7 and described movable iron 4.

Refer to Fig. 2 and Fig. 3, the application's armature location structure comprises described iron core 3 and described movable iron againSheet 4, the both sides of the edge of the lower end of described movable iron 4 offer opening 41, described opening 41 with described canBetween the end face of the lower end of moving iron plate 4, form pressure section 42, can described in two side direction of the lower end of described iron core 3Moving iron plate 4 directions are extended press keeping section 31, and described press keeping section 31 is placed in described opening 41 and presses on instituteState on pressure section 42, described press keeping section 31 contacts with the front edge of described pressure section 42 and forms axes O,Described movable iron 4 swings around described axes O. The lower surface of described pressure section 42 is arc between outsideShape 43, when preventing that described movable iron 4 from swinging described in pressure section 42 with around interfere.

Refer to Fig. 2 and Fig. 3, described armature location structure also comprises hook shell fragment 8, described hook shell fragment again8 are installed on described pedestal 1, and one end of described hook shell fragment 8 upwards extends to form elastic portion 81, described inElastic portion 81 flexibly presses on the outside of described movable iron 4, the lower end that makes described movable iron 4 nearIn the end face of the lower end of described iron core 3, and the elastic force of described elastic portion 81 is less than described moved end 7 selfRestoring force, thereby described moved end 7 can be separated with described static terminal 6; Described movable iron 4 and instituteState iron core 3 hearts and press close to the magnetic effect of the electromagnet that can strengthen, thereby make its more easily movable iron described in adhesiveThe upper end of sheet 4. The middle part of described hook shell fragment 8 is bent to form the recess 82 that holds described pressure section 42, instituteState recess 82 and be inverted trapezoidal structure; Described recess 82 can ensure described pressure section 42 and described press keeping section 31The reliability coordinating, thus make described movable iron 4 swing stable. The other end water of described hook shell fragment 8The flat fixed part 83 that extends to form, fixed part 83 is on described pedestal 1 described in described iron core 3 pressure holdings. By profitWith described fixed part 83, can make described hook shell fragment 8 be fixed on described pedestal 1, thereby described in ensureingThe elasticity of elastic portion 81 is effective.

Comprehensively above-mentioned, in the time of described electromagnet coil 2 logical little electric current, described iron core 3 produces magnetic field, passes throughThe upper end of movable iron 4 described in magnetic field suction, described in described movable iron 4 swings near and upper end presses close toIron core 3, meanwhile, the upper end of described movable iron 4 drives described moving part 5 translations, described moving part5 drive the upper end of described moved end 7 near described static terminal 6, when described moved end son 7 and described static terminal 6When conflict, described static terminal 6 is turning circuit with described moved end son 7 conductions, and heavy current is by described quiet endSon 6 and described moved end 7.

Compared with prior art, because the utility model is offered opening 41 in the lower end of described movable iron 4,Make to form pressure section 42 between the end face of lower end of described opening 41 and described movable iron 4, and at described ironThe lower end of core 3 arranges press keeping section 31, by described press keeping section 31 is snapped in described opening 41, therebyCan be by described press keeping section 31 pressure holdings on described pressure section 42, and described press keeping section 31 and described pressure section 42Contact position form axes O, therefore, can make described movable iron 4 realize and swinging around described axes O,Without using the supplementary structure such as york piece, simple and compact for structure, be conducive to the electromagnetic relay 100 of small sizeProduce and assembling; And by described hook shell fragment 8 is set, can make the lower end of described movable iron 4 press close toThe lower end of described iron core 3, effectively strengthens the magnetic effect of iron core 3, makes movable iron 4 described in its easier adhesive,Performance is more stable.

Above disclosed is only preferred embodiments of the present utility model, certainly can not limit this reality with thisBy novel interest field, the equivalent variations of therefore doing according to the utility model claim, still belongs toThe scope that the utility model is contained.
