Description
Technical field
The utility model relates to a kind of iron core, and more particularly, it relates to a kind of iron core of A.C. contactor.
Background technology
Contactor refers in industrial electro and utilizes coil current flowing to produce magnetic field, makes contact closure, to reach the electrical equipment of control load.Contactor is comprised of electromagnetic system (iron core, static iron core, solenoid) contact system (normally open contact and normally closed interlock) and arc-control device.Its principle is after the solenoid energising of contactor, and the long-living very strong magnetic field of meeting, makes static iron core produce electromagnetic attraction armature, and drives shake-up action, normally closed interlock disconnection, and normally open contact is closed, and both link; When coil blackout, electromagnetic attraction disappears, and armature discharges under the effect of retracting spring, and contact is restored, and normally closed interlock is closed, and normally open contact disconnects.
At present, application number is that 201220053990.1 Chinese patent discloses a kind of < < AC contactor iron core > >, it comprises iron core body, described iron core body comprises that the lamination of some E shape structures laminates setting and forms, each lamination includes a vertical portion and three transverse parts, and the transverse part end face of described intimate body is provided with short-circuited conducting sleeve.This AC contactor iron core, although can make magnetic field more stable, is not provided for the fixedly mechanism of short-circuited conducting sleeve, along with making short-circuited conducting sleeve occur loosening in long-term use procedure, comes off.
Utility model content
The deficiency existing for prior art, the purpose of this utility model be to provide a kind of energy fixedly short-circuited conducting sleeve make the adeciduate AC contactor iron core of short-circuited conducting sleeve.
For achieving the above object, the utility model provides following technical scheme: a kind of AC contactor iron core, comprise iron core body, described iron core body is formed by the silicon steel plate stacking setting of some E shape structures, described iron core body includes three transverse parts and a vertical portion, described three transverse parts are vertically connected on described vertical portion successively, the end face that is placed in two transverse parts of both sides in three transverse parts of described iron core body is equipped with short-circuited conducting sleeve, it is characterized in that: described end face offers groove, described short-circuited conducting sleeve is arranged in the transverse part end face groove of both sides, described groove one side channel mouth place arranges snap ring mechanism.
By adopting technique scheme, snap ring mechanism can be fixed on short-circuited conducting sleeve in groove firmly, and short-circuited conducting sleeve can not dropped in the iron core course of work, further to improve the stability in magnetic field.
The utility model is further set to: described snap ring mechanism is that leg-of-mutton double wedge forms by cross section.
By adopting technique scheme, double wedge in described snap ring mechanism, short-circuited conducting sleeve is made in the mode of punching press, short-circuited conducting sleeve is disposable to be embedded in groove, the structure that cross section is right-angled triangle can be given in punching course a buffering suface is provided, short-circuited conducting sleeve can conveniently be entered in groove, make short-circuited conducting sleeve below double wedge, like this when short-circuited conducting sleeve is loosening, even if mutually clamping effect with iron core groove loses, double wedge can also be limited in short-circuited conducting sleeve in groove and make it not come off, so just reach the effect of blocking short-circuited conducting sleeve, because adopting short-circuited conducting sleeve, it can make produced magnetic field more stable, snap ring mechanism can guarantee that short-circuited conducting sleeve is fixed in end face groove, guaranteed stable magnetic field work.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model AC contactor iron core embodiment;
Fig. 2 is the structure front view of the utility model AC contactor iron core embodiment.
Reference numeral: 1. iron core body; 2. rivet; 3.E shape silicon steel sheet; 4. short-circuited conducting sleeve; 5. middle part transverse part end face; 5.1,5.2 both sides transverse part end faces; 5.11. groove; 5.12. double wedge.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model AC contactor iron core embodiment is described further.
A kind of AC contactor iron core, comprise iron core body 1, described iron core body 1 is formed by the silicon steel plate stacking setting of some E shape structures, and further fixing by rivet 2, described iron core body 1 includes three transverse parts and a vertical portion, described three transverse parts are vertically connected on described vertical portion successively, in 1 three transverse parts of described iron core body, be placed in two transverse parts 5.1 of both sides, 5.2 end faces are equipped with short-circuited conducting sleeve 4, wherein, described short-circuited conducting sleeve 4 is arranged on the transverse part end face 5.1 of both sides, in 5.2 grooves 5.11, described groove 5.11 one side channel mouth places arrange snap ring mechanism.
Described snap ring mechanism is that leg-of-mutton double wedge 5.12 forms by cross section, and as Fig. 2, transverse part 5.1 end faces in left side are not for overlapping short-circuited conducting sleeve 4, and transverse part 5.2 end faces in right side are for putting short-circuited conducting sleeve 4.
By adopting technique scheme, double wedge 5.12 in described snap ring mechanism, short-circuited conducting sleeve 4 is made in the mode of punching press, short-circuited conducting sleeve 4 is disposable to be embedded in groove 5.11, the structure that cross section is right-angled triangle can be given in punching course a buffering suface is provided, short-circuited conducting sleeve 4 can easily be entered in groove 5.11 fast, therefore short-circuited conducting sleeve 4 is just in the below of double wedge 5.12, like this when short-circuited conducting sleeve 4 is loosening, even if mutually clamping effect with iron core groove 5.11 loses, double wedge 5.12 can also be limited in short-circuited conducting sleeve 4 in groove 5.11 and make it not come off, so just reach the effect of blocking short-circuited conducting sleeve 4.
In sum, the short-circuited conducting sleeve 4 of setting can make produced magnetic field more stable, and snap ring mechanism can guarantee that short-circuited conducting sleeve 4 is fixed in end face groove 5.11,5.12, has guaranteed stable magnetic field work.
The above is only preferred implementation of the present utility model, and protection range of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
