Abstract
The utility model discloses an iron core, and aims to provide an iron core which can make the magnetic field of an alternating current contactor more stable. The key points of the technical scheme comprise that the iron core of the alternating current contactor comprises an iron core body, the iron core body comprises a plurality of E-shaped iron core sheets and is formed by overlying the E-shaped iron core sheets, each iron core sheet comprises a vertical portion and three transverse portions, and end faces of the transverse portions of the iron core body are provided with short circuit rings. The iron core of the alternating current contactor has a simple structure and is suitable for various alternating current contactors.
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 (Contactor) is meant that utilizing coil to flow through electric current in the industrial electro produces magnetic field, makes contact closure, to reach the electrical equipment of control load.Contactor is made up 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, can produce very strong magnetic field, and make static iron core produce electromagnetic attraction and attract armature, and drive the contact action: normally closed interlock breaks off; 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: normally closed interlock is closed; Normally open contact breaks off.
Produce because the magnetic field of A.C. contactor is the alternating current by coil, and the size and Orientation of alternating current is to do cyclic variation in time that the alternating current that uses at present is that a frequency is 50 hertz a sine wave; So the magnetic field in the iron core equally is a sine wave with alternating current also; Magnetic force is done cyclic variation from just being up to 0 to negative maximum exactly so, and is not enough at 0 left and right sides magnetic force, will unclamp; And then adhesive; Unclamp, move in circles, contactor will be stablized and cisco unity malfunction because magnetic field inadequately like this.
Summary of the invention
To the deficiency that prior art exists, the purpose of the utility model is to provide a kind of magnetic field that can make contactor stable AC contactor iron core more.
For realizing above-mentioned purpose; The utility model provides following technical scheme: a kind of A.C. contactor iron core; Comprise the iron core body; Said iron core body comprises that the lamination of some " E " shape structure laminates setting and forms, and each lamination includes a vertical portion and three transverse parts, and the transverse part end face of said iron core body is provided with short-circuited conducting sleeve.
Through adopting technique scheme, add short-circuited conducting sleeve, induced current is arranged in the short circuit, it can stop this part changes of magnetic field, thereby makes magnetic force stable, and contactor just can operate as normal.
The utility model further is set to: place the end face of the transverse part of both sides to be provided with short-circuited conducting sleeve in said three transverse parts.
Through adopting technique scheme, can either guarantee the stability in contactor magnetic field, also waste material not.
The utility model further is set to: the surface of said iron core body is provided with the tufftride layer.
Through adopting technique scheme, tufftride is carried out on the surface of iron core handle, can effectively improve its useful life.
Description of drawings
Fig. 1 is the structural representation of the utility model A.C. contactor iron core embodiment.
Embodiment
With reference to Fig. 1 the utility model A.C. contactor iron core embodiment is further specified.
A kind of A.C. contactor iron core comprises iron core body 1, and said iron core body 1 comprises a vertical portion 111 and three transverse parts 112; Said vertical portion 111 is " E " shape with transverse part 112 and is provided with; (what need explain is that the described end face that is provided with the transverse part 112 of short-circuited conducting sleeve 113 can be the end face of three transverse parts 112, also can be the end face of a transverse part 112 here to place the end face of the transverse part 112 of both sides to be provided with short-circuited conducting sleeve 113 in the said iron core body 1; For making the stability that can either guarantee contactor magnetic field; Also waste material, present embodiment is preferred, described short-circuited conducting sleeve 113 places three transverse parts 112 to be positioned on the end face of transverse part 112 of both sides).
Through adopting technique scheme, add short-circuited conducting sleeve 113, induced current is arranged in the short circuit, it can stop this part changes of magnetic field, thereby makes magnetic force stable, and contactor just can operate as normal
The surface of said iron core body 1 is provided with tufftride layer 12.
Through adopting technique scheme, tufftride is carried out on the surface of iron core handle, can effectively improve its useful life.
