Abstract
A kind of inductance manganese-zinc ferrite core, including magnet ring body and permanent magnetic sheet are the utility model is related to, the longitudinal section of the magnet ring body is positive side shape, and cross section is square, and the permanent magnetic sheet is arranged in magnet ring body cross-section；Coil winding is close, safe, and service life length, thermal diffusivity is good, working strength and efficiency high.
Description
Technical field
The utility model belongs to magnetic core field, and in particular to a kind of inductance manganese-zinc ferrite core.
Background technology
Manganese-zinc ferrite is one kind of soft magnetic ferrite.Belong to spinel structure.By iron, manganese, zinc oxide and its salt
Class, it is made of ceramic process.It has high initial permeability.Typically used in 1 kilo hertz to 10 megahertzs of frequency range.
Inductor, transformer, the magnetic core of wave filter, magnetic head and aerial rod can be made.Its material typically has the surface impedance of very little, several
Equivalent to the good conductor of electricity, so such material there must be good insulating barrier to completely cut off coil body, otherwise easily produce
High-voltage breakdown between primary and secondary coil.Its feature is fitted has low power consumption under conditions of high frequency high magnetic flux density.
At present, the using priciple of the magnetic core of inductance is generally, longer magnet ring；More close aperture and the cable passed through
With reference to；More coil turn.The magnet ring used in the prior art, because it is annulus, coiling is caused to have to leave sky
In vain, and add air gap part, it is impossible to coiling, otherwise security can be affected.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of electricity to solve the above problems
Sense manganese-zinc ferrite core.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of inductance manganese-zinc ferrite core, including magnet ring body and permanent magnetic sheet, the longitudinal section of the magnet ring body
For positive side shape, cross section is square, and the permanent magnetic sheet is arranged in magnet ring body cross-section.
As preferable technical scheme, the longitudinal section of the magnet ring body is square, regular hexagon or octagon.
As preferable technical scheme, the quantity of the permanent magnetic sheet is 1-3, and every a line of the magnet ring body is extremely
It is provided with 1 permanent magnetic sheet more.
As preferable technical scheme, the longitudinal section of the magnet ring body is regular hexagon, the quantity of the permanent magnetic sheet
For 2,2 opposite side of magnet ring body are respectively arranged at.
The utility model has following beneficial technique effect relative to prior art：
At present, the using priciple of the magnetic core of inductance is generally, longer magnet ring；More close aperture and the cable passed through
With reference to more coil turn.The magnet ring used in the prior art, because it is annulus, coiling is caused to have to leave sky
In vain, and add air gap part, it is impossible to coiling, otherwise security can be affected.
（1）Using regular hexagon magnetic core, and cross section is arranged to square, enables to coil winding close, does not leave blank
In vain, overall performance is improved.
（2）Air gap is replaced using permanent magnetic sheet, security is improved, extends the service life of magnetic core.
（3）The design of magnet ring, it is possible to increase thermal diffusivity, so as to ensure that the working strength of inductance and efficiency.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model；
Fig. 2 is cross-sectional view of the present utility model；
In figure：1st, magnet ring body；2nd, permanent magnetic sheet.
Embodiment
The utility model will be further described with reference to the accompanying drawings and detailed description and explanation.The utility model
Description in, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width ", " thickness ",
" on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer ", " up time
The orientation or position relationship of the instruction such as pin ", " counterclockwise ", " axial direction ", " radial direction ", " circumference " be based on orientation shown in the drawings or
Position relationship, it is for only for ease of description the utility model and simplifies description, rather than indicates or imply signified device or member
Part must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
As illustrated, a kind of inductance manganese-zinc ferrite core, including magnet ring body 1 and permanent magnetic sheet 2, the magnet ring sheet
The longitudinal section of body 1 is positive side shape, and cross section is square, and the permanent magnetic sheet 2 is arranged on the cross section of magnet ring body 1；Institute
The longitudinal section for stating magnet ring body 1 is square, regular hexagon or octagon；The quantity of the permanent magnetic sheet 2 is 1-3,
Every a line of the magnet ring body 1 is at most provided with 1 permanent magnetic sheet；The longitudinal section of the magnet ring body 1 is regular hexagon, institute
The quantity for stating permanent magnetic sheet 2 is 2, is respectively arranged at 2 opposite side of magnet ring body 1.
Tested through inventor, in the case that control other conditions are consistent, using regular hexagon, 2 permanent magnetic sheets are set
Manganese-zinc ferrite core, properties behave oneself best.
Above-described is specific embodiment of the present utility model, it is impossible to limits protection model of the present utility model with this
Enclose, i.e., the equivalence changes made according to present utility model application the scope of the claims and description and modification, should all belong to this practicality
In the protection domain that new patent is covered.
