Abstract

The utility model provides a novel structure of an MFJ1-series AC electromagnetic armature and a coil. The novel structure of the MFJ1-series AC electromagnetic armature and the coil includes the coil (2), a solenoid (3), the electromagnetic armature (1) and an electromagnetic armature housing (5). The coil (2) is arranged in the upper part in the electromagnetic armature housing (5) and the solenoid (3) is arranged in the lower part. The coil (2) is coiled on the outer side of the wall of the solenoid (3). Opposite positions of the coil (2) and the solenoid (3) are partly overlapping. The novel structure of the MFJ1-series AC electromagnetic armature and the coil is characterized in the a head part (4) of the electromagnetic armature (1) is in clearance fit with the inner wall of the solenoid (3). According to the utility model, the coil moves along the inner wall of the solenoid under an effect of electromagnetic forces after the coil is electrified. That the electromagnetic armature hits or scratches the inner wall of the solenoid does not cause damages of an insulation layer on the surface of the coil or short circuit. Therefore, defects that damages of the insulating surface of the coil caused by crashes and scratches of the armature lead to short circuit and the like are made up.

Description

MFJ1 series exchanges with electromagnet armature and coil new construction

Technical field

The utility model relates to MFJ1 series and exchanges and use electromagnet, especially about the new construction of electromagnet armature and coil position.

Background technology

MFJ1 series exchanges and use electromagnet, be applicable to exchange valve with 50Hz or 60Hz voltage to the control circuit of 380V, cut the usefulness of the machine tool hydraulic control system switching electromagnetically operated valve that disappears as metal.The MFJ1 series AC solenoid for valve coil that market is generally purchased is inboard around iron core, and armature is side shifting in coil.Iron core and armature are magnetized behind coil electricity, become two blocks of relative magnet of polarity, produce electromagnetic attraction between them, and armature and iron core are sucked.Release under the effect of electric armature at reaction force when coil and to return original off-position.

Summary of the invention

Use each parts gap to increase and the vibration increase for overcoming MFJ1 series electromagnet owing to long-term, coil position is subjected to displacement, the purpose of this utility model is to provide a kind of electromagnet armature and coil new construction, around the screwed pipe wall outside with solenoid, electromagnet armature is inboard movable at screwed pipe, has avoided electromagnet armature and electromagnet casing easily collision and scratch coil insulation surface.

The technical solution of the utility model is achieved in the following ways: MFJ1 series exchanges with electromagnet armature and coil new construction, comprise coil, screwed pipe, electromagnet armature and electromagnet casing, the top is provided with coil in the electromagnet casing, the below is provided with screwed pipe, coil winding is in the screwed pipe wall outside, the relative position of coil and screwed pipe overlaps, and it is characterized in that: described electromagnet armature and head are by coil and screwed pipe inwall matched in clearance.

The T-shaped structure of described electromagnet armature, its head are working face, move up and down in the inwall of screwed pipe.

The utility model structure, electromagnet armature moves in the wall of screwed pipe under the effect of electromagnetic force behind the coil electricity, and electromagnet armature collision or scratch screwed pipe inwall can not make the coil surface insulating barrier damage or short circuit.The defectives such as armature collision and the surface short circuit of scratch coil insulation have been avoided.

Description of drawings

Fig. 1 is the structural representation of prior art.

Fig. 2 is structural representation of the present utility model.

Embodiment

Being known by Fig. 1, is the structural representation of prior art.This structure electromagnet armature 1 is side shifting in coil; electromagnet armature 1 and iron core adhesive easily produce vibration when coil 2 energising; long-time electromagnet armature and iron core adhesive, release coil 2 positions are easily mobile; electromagnet armature 1 and electromagnet casing often can collide or abrade coil surface, cause the coil surface insulating barrier to damage or short circuit.

Being known by Fig. 2, is structural representation of the present utility model.Comprise coil 2, screwed pipe 3, electromagnet armature 1 and electromagnet casing 5, coil 2 is wrapped in the interior top that the outer rear flank of screwed pipe 3 walls is arranged on electromagnet casing 5, screwed pipe 3 is located at the bottom of electromagnet casing 5, the relative position of coil 2 and screwed pipe 3 has partial fixing overlapping, described electromagnet armature 1 is arranged on screwed pipe 3 inside fronts and places in the coil 2, and the head 4 of electromagnet armature is in the inwall matched in clearance of screwed pipe 3.Electromagnet armature 1 T-shaped structure, its head 4 is working face, moves up and down in the inwall of screwed pipe 3.

The utility model, be with coil around the screwed pipe wall outside, the position of coil and screwed pipe is relative fixing, coil and electromagnet armature also have guiding with screwed pipe when releasing electricity condition, make current-carrying iron core, coil produce enough electromagnetic forces by calculating.Under the effect of electromagnetic force, electromagnet armature is the electromagnet long-term work only at screwed pipe wall inner surface movement, and each parts gap or vibration increase, electromagnet armature is in the motion of screwed pipe inwall place, and electromagnet armature collision or scratch screwed pipe inwall also are unlikely to make the coil surface insulating barrier to damage or short circuit.
