Detailed description of the invention
For describing technology contents of the present utility model, structural feature, the effect that realizes in detail, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
As shown in Figure 1 and Figure 2, this utility model electromagnetic relay 100 includes 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 takes the shape of the letter U structure, and described iron core 3 is in vertically and be fixably attached to described pedestal 1；Described electromagnet coil 2 is wound in outside described iron core 3；Described movable iron 4 is in vertical structure, and setting and lower end are movably arranged on described pedestal 1 vertically, the side of described movable iron 4 is in the face of the end face of described iron core 3, the upper end of described movable iron 4 is connected with described moving part 5 clamping, the other end of described moving part 5 is connected with the upper end of described moved end 7, the lower end of described moved end 7 and static terminal 6 is fixedly mounted on described pedestal 1, and described static terminal 6 is between described moved end 7 and described movable iron 4.
Refer to Fig. 2 and Fig. 3 again, the both sides of the edge of the lower end of described movable iron 4 offer opening 41, pressure section 42 is formed between the end face of the lower end of described opening 41 and described movable iron 4, press keeping section 31 is extended in two lateral described movable iron 4 directions of the lower end of described iron core 3, described press keeping section 31 is placed in described opening 41 and presses on described pressure section 42, described press keeping section 31 contacts formation axes O with the front edge of described pressure section 42, and described movable iron 4 swings around described axes O.The lower surface of described pressure section 42 between outside curved 43, with prevent described movable iron 4 when swinging described pressure section 42 interfere with surrounding.
Refer to Fig. 2 and Fig. 3 again, described electromagnetic relay 100 also includes hook shell fragment 8, described hook shell fragment 8 is installed on described pedestal 1, one end of described hook shell fragment 8 upwardly extends formation elastic 81, described elastic 81 flexibly presses on the outside of described movable iron 4, the lower end making described movable iron 4 is close proximity to the end face of the lower end of described iron core 3, and the elastic force of described elastic 81 is less than the restoring force of described moved end 7 self, so that described moved end 7 can separate with described static terminal 6；Described movable iron 4 and described iron core 3 heart press close to the magnetic effect of the electric magnet that can strengthen, so that the upper end of its more easily movable iron 4 described in adhesive.The middle part of described hook shell fragment 8 is bent to form the recess 82 holding described pressure section 42, and described recess 82 is in inverted trapezoidal structure；Described recess 82 can guarantee that the reliability that described pressure section 42 coordinates with described press keeping section 31, so that described movable iron 4 swings stable.The horizontal-extending formation fixed part 83 of the other end of described hook shell fragment 8, described in the pressure holding of described iron core 3, fixed part 83 is on described pedestal 1.By utilizing described fixed part 83, it is possible to make described hook shell fragment 8 be fixed on described pedestal 1, thus ensureing the elastic effective of described elastic 81.
Summary, when described electromagnet coil 2 leads to small area analysis, described iron core 3 produces magnetic field, upper end by movable iron described in magnetic field suction 4, described movable iron 4 swing near and upper end press close to described iron core 3, meanwhile, the upper end of described movable iron 4 drives described moving part 5 to translate, described moving part 5 drives the upper end of described moved end 7 near described static terminal 6, when described moved end 7 is conflicted with described static terminal 6, described static terminal 6 conducts electricity and turning circuit with described moved end 7, and heavy current passes through described static terminal 6 and described moved end 7.
Compared with prior art, owing to this utility model offers opening 41 in the lower end of described movable iron 4, make described opening 41 and described movable iron 4 lower end end face between formed pressure section 42, and press keeping section 31 is set in the lower end of described iron core 3, by described press keeping section 31 is snapped in described opening 41, thus can by the pressure holding of described press keeping section 31 on described pressure section 42, and the contact position of described press keeping section 31 and described pressure section 42 forms axes O, therefore, described movable iron 4 can be made to realize swinging around described axes O, without using the supplementary structures such as york piece, simple and compact for structure, be conducive to production and the assembling of the electromagnetic relay 100 of small size；And by arranging described hook shell fragment 8, it is possible to make the lower end of described movable iron 4 press close to the lower end of described iron core 3, effectively strengthen the magnetic effect of iron core 3 so that it is being easier to movable iron 4 described in adhesive, performance is more stable.
Above disclosed it is only preferred embodiments of the present utility model, certainly can not limit the interest field of this utility model, the equivalent variations therefore made according to this utility model claim with this, still fall within the scope that this utility model is contained.
