Description
Technical field
The present invention relates to a kind of magnetic-holding electric magnet, relate in particular to a kind of miniature two-way magnetic-holding electric magnet.
Background technology
Chinese patent numbers 89218596.1 is called the direct-push bidirection magnetic maintainer, and principle is made up of yoke, permanent magnet, solenoid and iron core, yoke divide go up in three parts down, intermediate section is furnished with opposite polarity permanent magnet and two coils of two groups of symmetries.Chinese patent number 02206165.7 is called two-way magnetic-holding electric magnet; Principle is that the permanent magnet both sides respectively have independently solenoid, and the magnetic flux that solenoid produces runs through permanent magnet, and the flow direction with permanent magnet is identical all the time; Respectively independently solenoid is switched on successively, armature switching-over motion.Their main weak points are: used two coils, caused to reach littler on the volume, the consistent difficulty of the active force of two-way maintenance increases, the increase of parts simultaneously, and the probability of the fault of generation also can increase.
Present a lot of electronic products on the market are more and more littler; And the purposes of two-way magnetic-holding electric magnet is very extensive; Therefore the volume to two-way magnetic-holding electric magnet had higher requirement, yet two-way magnetic-holding electric magnet had the people to declare about two-way magnetic-holding electric magnet patent until now from 1989; 20 years still can't keep the volume of electromagnet to make bigger improvement to two-way magnetic.
Present magnetic-holding electric magnet can not used in the device at miniature volume on the volume, and the active force of two-way maintenance is also inconsistent, cisco unity malfunction under low temperature and hot environment.
Summary of the invention
The technical problem that the present invention will solve is: adopt twin coil to cause the excessive and permanent magnet of volume to cause the inconsistent problem of confining force easily in the middle of being positioned at two coils in order to solve present two-way magnetic-holding electric magnet; The present invention provides a kind of miniature two-way magnetic-holding electric magnet; Adopt a coil to replace two coils, permanent magnet is positioned at the axial two ends of coil and solves the problems referred to above.
The technical solution adopted for the present invention to solve the technical problems is: a kind of miniature two-way magnetic-holding electric magnet, comprise yoke framework and the base plate that is arranged on yoke framework bottom, and be provided with an insulated tube in the said yoke framework; Be wound with coil on the said insulated tube; The direction of winding of said coil is parallel with base plate, and permanent magnet is equipped with at the axial two ends of said coil respectively, and the one side of said two permanent magnet homopolarities is oppositely arranged; Be provided with moving iron core in the said insulated tube; Said coil is connected with power supply lead wire, and magnetic conductive cover is equipped with in the top of said yoke framework, is connected with the action metallic rod on the said moving iron core; Said action metallic rod is perpendicular to base plate, and said action metallic rod one end stretches out from base plate.
In order to reduce the influence of environment, the material of described base plate is a steel.
For volume is littler, described permanent magnet is a thin rounded flakes.
Further, specifically, said miniature two-way magnetic-holding electric magnet length is 12.5mm-25mm, and width is 8mm-20mm, highly is 6.4mm-15mm.
Further, as preferably, said miniature two-way magnetic-holding electric magnet length is 12.5mm, and width is 8mm, highly is 6.4mm.
As preferably, described action metallic rod is the copper bar.
The invention has the beneficial effects as follows; A kind of miniature two-way magnetic-holding electric magnet of the present invention adopts a coil to replace two traditional coils, makes the volume of two-way magnetic-holding electric magnet reduce greatly; The minimizing of part; Failure rate also can reduce, and monocoil axial two ends are provided with permanent magnet and replace in the middle of two traditional coils permanent magnet being set, and the confining force unanimity is also played a role; The base plate steel design has replaced some traditional plastic constructions simultaneously, makes environment also reduce greatly its influence.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the optimum embodiment of the miniature two-way magnetic-holding electric magnet of the present invention.
Among the figure 1, the yoke framework, 2, base plate, 3, coil, 4, permanent magnet, 5, moving iron core, 6, power supply lead wire, 7, magnetic conductive cover, 8, the action metallic rod.
Embodiment
Combine accompanying drawing that the present invention is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
