Abstract
The utility model discloses an iron core, and aims to provide an iron core used on a contactor. The key points of the technical scheme comprise that the novel iron core comprises an iron core body, the iron core body is formed by a plurality of silicon steel sheets in an overlying mode, rust preventive petrolatum is provided between adjacent silicon steel sheets, each silicon steel sheet of the iron core is E-shaped, the iron core is formed by the E-shaped silicon steel sheets, the silicon steel sheets are connected through rivets, and the E shape of each silicon steel sheet is provided with a 0.15mm to 0.2mm demagnetization gap.
Description
Technical field
The utility model relates to a kind of iron core, and more particularly, it relates to the iron core that uses on a kind of 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.
The iron core of contactor generally all gets rusty easily, and influences the useful life of iron core.
Summary of the invention
To the deficiency that prior art exists, the purpose of the utility model is the iron core that provides a kind of longer service life of a specified duration.
For realizing above-mentioned purpose, the utility model provides following technical scheme: the iron core of using on a kind of contactor, comprise the iron core body, and said iron core body is formed by some silicon steel plate stacking settings, is provided with antirust oil between said each silicon steel sheet.
Through adopting technique scheme, can effectively prevent to get rusty between each silicon steel sheet, influence useful life.
The utility model further is set to: each silicon steel sheet of described iron core is the setting of " E " type structure and forms, and riveted joint is connected with rivet between the silicon steel sheet.
Through adopting technique scheme, make that the structure of iron core is compact more, the long perfomance life of iron core.
The utility model further is set to: said " E " shape silicon steel sheet is provided with the magnetic gap of dispelling of 0.15mm-0.2mm.
Through adopting technique scheme; Silicon steel sheet is excessive because of magnetic field magnetic force, can cause iron core not decontrol or discharged and make that slowly contactor can't operate as normal, very easily causes equipment fault and the personal safety accident occurs; So must manage to remove, technique scheme just can effectively address this problem.
Description of drawings
Fig. 1 is the structural representation of the utility model iron core embodiment.
Embodiment
With reference to Fig. 1 the utility model iron core embodiment is further specified.
The iron core of using on a kind of contactor comprises iron core body 1, and said iron core body 1 is laminated to be provided with by some silicon steel sheets 11 and forms, and is provided with antirust oil 13 between said each silicon steel sheet 11.
Through adopting technique scheme, can effectively prevent to get rusty between each silicon steel sheet 11, influence useful life.
Each silicon steel sheet 11 of described iron core is the setting of " E " type structure and forms, and riveted joint is connected with rivet 12 between the silicon steel sheet 11.
Through adopting technique scheme, make that the structure of iron core is compact more, the long perfomance life of iron core.
Said " E " shape silicon steel sheet 11 is provided with the magnetic gap 14 of dispelling of 0.15mm-0.2mm.
Through adopting technique scheme, avoid silicon steel sheet 11 excessive, and cause contactor to work because of magnetic field magnetic force, so just be difficult for causing equipment fault and the personal safety accident occurs.
