Weak, magnetic flow convertor misoperation, both, in high current environment, coil cold situation lower core also can be automatic for magnetic flow convertor
Outwards eject, can not meet high current application, the defect of opposing high current magnetic field ability, a kind of magnetic flux conversion is provided
Device, thus solve the above problems.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of magnetic flow convertor of the present invention, including the shell that iron core is overall and overall for fixing described iron core, described
Iron core integrally includes upper core and lower core, is connected as entirety by internal and external threads between described upper core and described lower core,
Described upper core top is provided with stage clip, and described stage clip is provided with inner cover, and described stage clip and described inner cover are each attached to outer cover
Inside, described outer cover top is provided with spacing collar, and described stage clip and described upper core are all connected with push rod, and described push rod side sets
It is equipped with lever, described lever is fixedly connected bearing by pin, described bearing is fixed on the pedestal of described shell, described lower core
Connect the yoke of bottom through described pedestal, described yoke is connected with magnet, described yoke bottom connects coil rack, described magnetic
Iron, described yoke and described coil rack are all fixedly installed on described inside the shell.
As a preferred technical solution of the present invention, described lower core is the permeability magnetic material of electromagnetic pure iron, and length is
22mm.
As a preferred technical solution of the present invention, described upper core is copper, the non-magnet material of aluminium alloy, and length is
12.8mm.
As a preferred technical solution of the present invention, described shell is connected outside by lead-out wire.
The beneficial effect that the present invention is reached is: a kind of magnetic flow convertor of the present invention, according to electromagnetic induction principle, energising
Coil produce electric field, in the case of coil electricity, electric field force overcomes magnetic field force, be in compressive state stage clip moment stretch make iron
The overall motion outwards ejecting, driving push rod and lever of core, automatically resets to original state under external force.In order to reduce iron
The overall leakage naked in attracting state of core is subject to the length of magnetic interference outside, and iron core is integrally segmented into upper core and lower core two
Point, lower core is electromagnetic pure iron, and upper core is non-magnet material, such as copper, aluminium alloy etc., because upper core is non-magnet material, outward
Boundary weakens significantly to the interference of magnetic flow convertor internal magnetic field in high current magnetic field, thus solving the problems, such as heavy current magnetic field,
The ability that product resists high current magnetic field greatly enhances, and can be applicable in high current environment.
