Problems solved by technology

[0002] The electromagnet is a common electrical component. The existing electromagnet generally includes a coil skeleton, a static iron core of the coil and a moving iron core. Since the moving iron core is placed in the center hole of the coil frame in a free state, a large impact force is generated at the moment when the moving iron core is attracted, resulting in a large noise, which is not conducive to environmental protection. In addition , this impact force will also cause vibration of other electrical components installed together with the electromagnet, which will easily cause damage to other electrical components

Abstract

The invention discloses a structure of an electromagnet. On the basis of an existing electromagnet structure, the structure provided by the invention is characterized in that a plug and a cushioned cylinder are arranged at the bottom of a movable iron core and in the middle of the bottom, corresponding to the bottom of the fixed iron core, of the movable iron core respectively, and the aim of cushioning can be achieved through the damping effect of the piston entering the cushioned cylinder. The structure disclosed by the invention has the advantages of low noise, slight vibration and long service life.

Description

technical field [0001] The invention relates to a structure of an electromagnet, which belongs to the technical field of electrical components. Background technique [0002] The electromagnet is a common electrical component. The existing electromagnet generally includes a coil skeleton, a static iron core of the coil and a moving iron core. Since the moving iron core is placed in the center hole of the coil frame in a free state, a large impact force is generated at the moment when the moving iron core is attracted, resulting in a large noise, which is not conducive to environmental protection. In addition , This impact force will also cause vibration of other electrical components installed together with the electromagnet, which will easily cause damage to other electrical components. Contents of the invention [0003] The object of the present invention is to provide a novel electromagnet to overcome the above-mentioned defects in the existing electromagnets. [0004]...
