Abstract
The invention relates to an electromagnet. An electromagnetic coil is coiled in an electromagnetic static iron core; casing coupling type moveable iron cores are arranged in central holes of the electromagnetic static iron core; the casing coupling type moveable iron cores are composed of a plurality of moveable sections which are different in diameter size and are coupled with each other; and a spring is arranged between two connected casing coupling type moveable iron cores. According to the invention, the purpose of prolonging an operating distance of the electromagnet is achieved and the electromagnet can meet the use requirements on special occasions.
Description
Technical field
The present invention relates to a kind of electromagnet, belong to the electric elements technical field.
Background technology
At present, the moving iron core of existing electromagnet all is the version of an integral body, because the length of the moving iron core of the structure of this integral body is generally all shorter, so what the iron core of electromagnet can act on is limited in scope, in some special situations, because the sphere of action of moving iron core is too short, can't adapts to some special occasions and use, for example: require can the go directly inside of member of iron core, simultaneously, iron core does not consist of interference to other parts again; For another example: require the iron core of electromagnet can touch the travel switch of distant place, other parts are not brought again the situation of interference simultaneously, so existing electromagnet can't reach above-mentioned requirements.
Summary of the invention
The object of the invention is to: can't satisfy some special occasions for existing electromagnet and use, especially require to have the employed defective of yard of operating distance far away, the invention provides a kind of novel electromagnet.
A kind of electromagnet of the present invention, it comprises electromagnetism static iron core, solenoid, the moving iron core of expansion joint type, spring, it is characterized in that, described electromagnetism static iron core is to have the good material of permeability magnetic material to make, in the electromagnetism static iron core, be wound with solenoid, in the interstitial hole of electromagnetism static iron core, be provided with the moving iron core of casing coupling formula, the moving iron core of described casing coupling formula is comprised of the active section that some the diameter that connect together each other differ, and between the moving iron core of two the casing coupling formulas that link to each other spring is set.
Beneficial effect: the present invention can adapt to the instructions for use of some special occasions owing to after adopting said method, by the moving Telescopic of iron core under spring and electromagnetic force of casing coupling formula, reach the purpose of the operating distance that prolongs electromagnet.
Description of drawings
Accompanying drawing is structure principle chart of the present invention.
Shown in the figure: 1, electromagnetism static iron core; 2, solenoid; 3, the moving iron core of expansion joint type; 4, spring.
