Description
Technical field
The present invention relates to magnetic core manufacture field, more particularly to a kind of ferrite inductance magnetic core.
Background technology
FERRITE CORE is a kind of high frequency permeability magnetic material, with high magnetic permeability and the characteristics of high magnetic flux density, its
There is rectangle air gap in middle FERRITE CORE, the presence of the air gap can avoid magnetic saturation, reduce remanent magnetism, increases
Plus weber capacity, while magnetic circuit equivalent length can also be increased, and then increase energy storage.But, rectangle air gap
Presence also make FERRITE CORE there are some drawbacks, such as inductive energy storage amount is low, leakage inductance amount is big, electromagnetic noise
Big the problems such as.
The content of the invention

High inductive energy storage, reduction leakage inductance, while electromagnetic noise can also be reduced.
The technical scheme is that what is be achieved in that：
A kind of ferrite inductance magnetic core, including magnetic core, the first air gap and interstice；
First air gap and the interstice are opened in respectively the magnetic core both sides；
First air gap and the interstice are parallelogram air gap, first air gap and described
Interstice is 10 °～80 ° with the magnetic core upper and lower surface angulation.
Preferably, the magnetic core is cube magnetic core.
Preferably, first air gap and the interstice are parallel to each other.
Preferably, first air gap and the interstice with the magnetic core upper and lower surface angulation
For 30 °～60 °.
Preferably, the magnetic core upper and lower ends are respectively arranged with the 3rd air gap and the 4th air gap.
Preferably, the 3rd air gap and the 4th air gap are parallelogram air gap.
Preferably, the magnetic core upper and lower ends are respectively arranged with the 5th air gap and the 6th air gap.
Preferably, the 3rd air gap and the 5th air gap are parallel to each other, the 4th air gap and described
Six air gaps are parallel to each other.
From above-mentioned technical proposal as can be seen that compared with rectangle air gap in prior art, the present invention is by magnetic
Core both sides arrange oblique first air gap and interstice, increased air gap area, air gap are reduced, so as to carry
High inductive energy storage.In addition, ferrite inductance magnetic core disclosed by the invention can reduce leakage inductance amount and electromagnetism is made an uproar
Sound, while so that air gap losses are reduced.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the invention, rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
Property work under the premise of the every other embodiment that obtained, belong to the scope of protection of the invention.
As shown in figure 1, the ferrite inductance magnetic core that the present invention is provided, including magnetic core 1, the first air gap 2 and the
Two air gaps 3.
The magnetic core 1 is used for increasing electromagnetic intensity, and the magnetic core 1 can be cube magnetic core, work as magnetic
When core 1 is FERRITE CORE, ferrite inductance magnetic core has stronger electromagnetic intensity.
First air gap 2 and the interstice 3 are used to increase inductive energy storage, the He of the first air gap 2
The interstice 3 is opened in the both sides of magnetic core 1, and first air gap 2 and the interstice 3 are
Parallelogram air gap, first air gap 2 and the interstice 3 with the upper and lower surface of the magnetic core 1
Angulation is 10 °～80 °；The oblique section air gap of quadrangle by arranging in the both sides of magnetic core 1 of the invention,
Increased air gap area and inductive energy storage.It should be noted that when first air gap 2 and second gas
Gap 3 is parallel to each other, first air gap 2 and the interstice 3 and the upper and lower surface of the magnetic core 1 institute into
Angle be 30 °～60 ° when, inductive energy storage amount is larger.
Additionally, for the distribution of the balanced magnetic line of force, inductive energy storage is improve, while reducing air gap losses and inductance
Noise, the upper and lower ends of the magnetic core 1 are respectively equipped with the 3rd air gap 4 and the 4th air gap 5, the 3rd air gap 4
It is fit clearance with the 4th air gap 5；When the 3rd air gap 4 and the 4th air gap 5 are parallel four
During the shape air gap of side, the effect of magnetic line of force distribution is best.It should be noted that the upper and lower ends of magnetic core 1 can be with
It is respectively equipped with the 5th air gap 6 and the 6th air gap 7；When the 5th air gap 6 is mutually put down with the 3rd air gap 4
OK, when the 6th air gap 7 is parallel to each other with the 4th air gap 5, core inductance energy storage is larger.
In addition it is also necessary to explanation, the 3rd air gap 4, the 4th air gap 5, the 5th air gap 6 and the 6th air gap
7 small air gaps for being 50～100 μm, for small air gap is compared to big air gap, can more improve inductive energy storage, drop
Low air gap losses and noise.
