Abstract
The utility model relates to an electromagnet capable of eliminating residual magnetism, which comprises a coil (3) and an iron frame body (4), wherein the iron frame body (4) supports the coil (3), iron cores are arranged in the coil (3), the iron cores consist of a fixed iron core (1) and a movable iron core (5), the fixed iron core (1) is engaged with a conical concave head arranged at the upper end of the movable iron core (5) through a conical convex head arranged at the lower end of the fixed iron core (1), the crossed part of a body and the conical convex head of the fixed iron core (1) is provided with a groove, and a magnetism insulation gasket (2) is arranged in the groove. The magnetism insulation gasket (2) has the thickness of 0.2 to 0.4mm, and is made of a rubber gasket. Through the electromagnet residual magnetism elimination technology provided by the utility model, the electromagnet does not have the residual magnetism phenomenon after power failure, the movable iron core is released immediately after the power failure, and the utility model can be applied to industries with the requirements on residual magnetism at present.
Description
Technical field
The utility model belongs to the electromagnet technical field, particularly relates to a kind of electromagnet of eliminating residual magnetism.
Background technology
Owing to can be magnetized by the short time after the electromagnet core energising, according to original electromagnet mechanism design, outage back movable core also has residual magnetism, still is adsorbed on the secured core, can't normal operation if the pulling force of customer facility, can have influence on the part customer facility less than residual magnetism.
Summary of the invention
Technical problem to be solved in the utility model provides the electromagnet that can eliminate the electromagnet residual magnetism after a kind of electromagnet cuts off the power supply.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electromagnet of eliminating residual magnetism is provided, comprise coil, the chase body of support coils, cored in the described coil, described iron core is divided into secured core and movable core, described secured core agrees with the recessed head of the circular cone of movable core upper end mutually by the circular cone plush copper of its lower end, and the intersection of the body of described secured core and circular cone plush copper has groove, and residual shim is installed in groove.
Described residual shim thickness is 0.2 ~ 0.4mm, and material is a rubber sheet gasket.
Beneficial effect
The elimination electromagnet residual magnetism technology that the utility model provides can make the no residual magnetism phenomenon in electromagnet outage back, and movable core discharges after outage at once, can be applied to the industry that at present residual magnetism is had requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model secured core structural representation.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, 2, the utility model comprises coil 3, the chase body 4 of support coils 3, cored in the coil 3, described iron core is divided into secured core 1 and movable core 5, described secured core 1 agrees with the recessed head of the circular cone of movable core 5 upper ends mutually by the circular cone plush copper of its lower end, and the intersection of the body of described secured core 1 and circular cone plush copper has groove, and residual shim 2 is installed in groove.
Described residual shim 2 thickness are 0.2 ~ 0.4mm, and material is a rubber sheet gasket.
Aly be used for electromagnet on the client electronic lock, major function can be opened for the energising rear lock core, the self-locking of outage rear lock core.Install original design electromagnet, the outage rear lock core can also be opened, and does not have auto-lock function.
New electromagnet is installed, behind the increase elimination residual magnetism pad, just can be satisfied client's functional requirement.
Be residual magnetism and attraction contrast before and after the exploitation below:
| ? | Residual magnetism | Attraction | ? |
| After the exploitation | 5G | 250G | ? |
| Before the exploitation | 100G | 235G | ? |
Claims (2)
1. the electromagnet that can eliminate residual magnetism, comprise coil (3), the chase body (4) of support coils (3), cored in the described coil (3), it is characterized in that: described iron core is divided into secured core (1) and movable core (5), described secured core (1) agrees with the recessed head of the circular cone of movable core (5) upper end mutually by the circular cone plush copper of its lower end, the body of described secured core (1) and the intersection of circular cone plush copper have groove, and residual shim (2) is installed in groove.
