Description

A kind of iron sial inductor

Technical field

The present invention relates to inductors technique field, in particular to a kind of iron sial inductor.

Background technique

Inductor is the element that electric energy can be converted into magnetic energy and stored.The structure of inductor is similar to transformation Device, but only one winding.Inductor has certain inductance, it only hinders the variation of electric current.If inductor is in no electricity In the state that stream passes through, it will attempt that electric current is hindered to flow through it when circuit is connected；If inductor is in the state for having electric current to pass through Under, it will attempt to maintain electric current constant when circuit disconnects.Inductor is also known as choke, reactor, dynamic reactor.

Wherein, iron sial inductor is inductor using Fe-Si-Al magnetic core, and doing can eliminate using gap ferrite magnetic Bring unfavorable factor when ring: one, ferritic magnetic flux density is equal to or less than 0.5T, and the value is even less than sendust Half.Thus under equal volume, ferrite energy storage capacity will also be lower than sendust；Two, in addition, ferritic saturation flux Density declines to a great extent under the high temperature conditions, and hot conditions do not make significant difference to iron sial then；Three, Ferrite Material has quick The characteristic of saturation is likely to result in inductance performance and integrally collapses if exceeding safe current value, and iron silica-alumina material has soft saturation Characteristic, the current value that can be born are higher；Four, the air gap diffusion edge loss opened in air gap ferrite inductor is very serious, and This problem is then not present in iron silica-alumina material；Five, sendust core is highly suitable for the energy storage filter inductor in Switching Power Supply. Compared with onesize and magnetic conductivity gap ferrite or ferrocart core, the sendust core of 10500 Gauss saturation degrees is provided more The ability of high storage energy；Six, compared with ferrocart core, the performance of iron sial at high temperature is preferable, in some applications, uses Iron sial is also more smaller than with ferrocart core；Seven, must pass through large-scale alternating voltage, the noise filtered electrical without generating saturation In sensor, it is very suitable to using sendust core.Size in line filter can be reduced using sendust core, since it is desired that Turn ratio is few using ferrite.Iron sial also has the magnetostriction coefficient close to zero, that is to say, that in audible frequency range Noise or in the rough work of line current it is very quiet；Eight, the characteristic of high magnetic flux density and low core loss keeps sendust core non- The often application suitable for circuit of power factor correction and unidirectional drive, such as kickback transformer, pulse transformer.So iron silicon Aluminium inductor using more and more extensive.

Currently, existing iron sial inductor is all iron sial such as Fig. 4 of copper wire winding circular ring shape, and the disadvantage is that: one, body Product is big；Two, production needs manually around copper wire, can not fully-automatic production；Three, thermal diffusivity is bad；Four, energy storage is not good enough.

Summary of the invention

The invention mainly solves the technical problem of providing a kind of iron sial inductor, structure is able to achieve full-automatic life It produces, it is small in size, thermal diffusivity is good, energy storage is good.

To solve the above-mentioned problems, the present invention provides a kind of iron sial inductor, including iron sialic crust, copper wire, iron sial Lid；The iron sialic crust, iron sial lid material be all iron sial；The iron sialic crust is oblateness, is equipped with circular groove, The centre of the circular groove is equipped with cylinder, and the side of the groove (11) is equipped with the first foot slot, crus secunda slot；The cylinder, First foot slot, crus secunda slot are on the same line；The copper wire is coiled into coil, and both ends are set to the first pin, second draw Foot, and the size of coil and cylinder coincide；The coil is on cylinder, and the first pin passes through the first foot slot, second pin Across crus secunda slot, on the iron sial lid Gai Tie sialic crust.

Furtherly, the coil can be single layer, can also be multilayer.

Furtherly, the material of the copper wire is copper.

Furtherly, the iron sial lid can also be equipped with the first lid groove, the second lid groove；The iron sial lid Gai Tie On sialic crust, first pin may further pass through the first lid groove, second pin may further pass through the second lid groove.

The invention discloses a kind of iron sial inductors, including iron sialic crust, copper wire, iron sial lid；The iron sialic crust, The material of iron sial lid is all iron sial；The iron sialic crust is oblateness, circular groove is equipped with, in the circular groove Between be equipped with cylinder, the side of the groove is equipped with the first foot hole, crus secunda hole；The beneficial effects of the present invention are: traditional iron Sial inductor is that annulus winds copper coil, and the design adopts the cylinder among copper coil winding iron sial, and has iron sial lid Son covers；Its structure has been able to achieve automated production, improves production efficiency, saves labour turnover；And volume is smaller, thermal diffusivity and Energy storage is more preferable.
