In the embodiment of the present invention, referring to fig. 1 and combining with fig. 2, the inductance device includes a magnetic core 1 and two windings 2, wherein the magnetic core 1 is annularly disposed, two magnetic protrusions 11 oppositely disposed are protruded on an inner wall of the magnetic core 1, and the two magnetic protrusions 11 cooperate to form a gap 12; the two windings 2 are respectively wound on two sides of the magnetic core 1, and the two magnetic protrusions 11 and the gap 12 are positioned between the two windings 2.
In the embodiment, the material of the magnetic core 1 is a magnetic metal oxide, such as manganese-zinc ferrite, nickel-zinc ferrite, etc., the magnetic core 1 is disposed in a ring shape, the magnetic core 1 encloses to form a cavity, and the magnetic protrusion 11 is disposed on an inner wall of the cavity. Preferably, the shape of the magnetic core 1 is a square frame shape, so that the magnetic core 1 can be easily molded, and the winding 2 can be easily wound on the frame on any side of the magnetic core 1.
The magnetic protrusions 11 are of a magnetic protrusion structure, the material of the magnetic protrusions 11 is also a magnetic metal oxide, and the magnetic protrusions 11 have the characteristics of high magnetic permeability and high magnetic flux density, so that the magnetic induction intensity of the electrified winding 2 can be effectively increased, magnetic induction lines emitted by the winding 2 relatively and intensively penetrate through the two magnetic protrusions 11, and concentrated magnetic leakage is generated at the gap 12. The cross-sectional shape of the gap 12 may be rectangular, circular, oval, etc., and is not limited thereto.
The two magnetic projections 11 are arranged opposite each other and extend toward each other. The gap 12 is a gap between the two magnetic protrusions 11, and the gap 12 has a strong magnetic resistance, that is, when the magnetic induction lines emitted after the winding 2 is electrified pass through the gap 12, the magnetic induction lines irregularly diverge in each direction at the gap 12, that is, a magnetic leakage phenomenon occurs. The leakage flux is concentrated at the gap 12 and thus has a strong strength and a high density, thereby forming a strong concentrated differential mode inductance with which differential mode interference can be effectively filtered.
The winding 2 is a multi-turn metal conductive coil, the winding 2 is wound on the magnetic core 1 and distributed on two sides of the magnetic protrusions 11, when the winding 2 is electrified, an electromagnetic induction magnetic field is generated, magnetic field lines of the magnetic field penetrate through the two magnetic protrusions 11 and are dispersed at the gap 12, and a magnetic leakage phenomenon occurs.
The scheme of the embodiment is that two oppositely arranged magnetic protrusions 11 are arranged on the annular magnetic core 1, and a gap 12 is formed between the two magnetic protrusions 11, wherein the gap 12 has a large magnetic resistance. When the winding 2 is wound on both sides of the core 1 and current is applied, the magnetic induction lines generated by the winding 2 are diffused in all directions at the gap 12, so that strong and concentrated leakage flux, i.e., strong and concentrated differential mode inductance, is formed. Therefore, the utility model provides an inductance device can promote inductance device to the decay intensity of differential mode interference, realizes excellent electromagnetic interference filter effect.
In an embodiment of the present invention, the two magnetic protrusions 11 and the magnetic core 1 are integrally formed.
In the embodiment, magnetism is protruding 11 and magnetic core 1 is integrated into one piece structure to save this inductance device's manufacturing procedure, be favorable to promoting magnetism protruding 11 and magnetic core 1 complex wholeness and compactness simultaneously, so that the magnetism line of inducting that makes winding 2 send after the circular telegram can directly pass magnetism protruding 11, and can not lead to the magnetic leakage not concentrating because magnetism is protruding 11 and magnetic core 1 is connected inseparably or there is gap or breach to cause the magnetic leakage between magnetism protruding 11 and the magnetic core 1.
By integrally forming the magnetic protrusions 11 and the magnetic core 1, after the winding 2 is electrified, magnetic induction lines emitted by the winding 2 can intensively penetrate the magnetic protrusions 11, and strong and concentrated magnetic leakage is generated at the gap 12, so that strong and concentrated differential mode inductance is formed, and the differential mode interference can be filtered more effectively by the inductance device.
In an embodiment of the present invention, the two magnetic protrusions 11 are both in a column shape, and the cross-sectional shape of the magnetic protrusions 11 is one of a circle, a rectangle, a rhombus and an ellipse.
In the embodiment, the magnetic protrusions 11 are arranged in a column shape, and the cross section of the magnetic protrusions 11 can be one of a circle, a rectangle, a rhombus and an ellipse, so that on one hand, the magnetic protrusions 11 are easy to machine and form; on the other hand, the columnar structure can concentrate and pass through more magnetic induction lines, which is beneficial to improving the density of the magnetic induction lines passing through the magnetic protrusions 11, thereby enhancing the strength and concentration of the magnetic leakage occurring at the gaps 12. Of course, the shape of the magnetic protrusions 11 may also be a plate shape, a strip shape, etc., and the shape of the magnetic protrusions 11 provided in this embodiment is only an alternative embodiment, and is not meant to be the only limitation on the shape of the magnetic protrusions 11.

In this embodiment, the concave surface 111 has a larger magnetic induction line diverging area than the flat surface, and the concave surface 111 converges and concentrates the magnetic induction lines more easily, so that the magnetic leakage at the gap 12 can be more concentrated by the concave surface 111 at the end of the two magnetic protrusions 11 away from the magnetic core 1, which is beneficial to improving the differential mode inductance at the gap 12 and enhancing the attenuation effect of the inductance device on the differential mode interference.
In an embodiment of the present invention, as shown in fig. 1, the width of the gap 12 is defined as L1, L1 is greater than or equal to 1mm and less than or equal to 3 mm.
In this embodiment, the width of the gap 12 affects the intensity and concentration of leakage flux, and when the width L1 of the gap 12 is 1mm or more and 3mm or less, the gap 12 does not cause a small amount of leakage flux due to an excessively small width, and does not cause leakage flux not to be concentrated and leakage flux intensity to be excessively weak for an excessively large width. Therefore, the inductance device can realize the filtering effect of the ideal differential mode inductance.

Secondly, a certain interval is reserved between the winding 2 and the magnetic projection 11, and the magnetic core 1 and the winding 2 are convenient to overhaul. In addition, leakage flux is generated at the gap 12, and it is also necessary to ensure a certain space in the vicinity of the gap 12 for the leakage flux to be emitted outward, and the leakage flux preferably does not adversely affect the magnetic field generated by the winding 2. Therefore, the distance between the winding 2 and the magnetic projection 11 is set to be more than or equal to 2mm, so that the overhaul and the maintenance of the winding 2 and the magnetic core 1 are facilitated, meanwhile, enough divergent space is provided for magnetic leakage, and the further formation of the magnetic leakage is facilitated.

Therefore, after the two windings 2 are electrified, the strength of the magnetic induction lines which penetrate through the magnetic protrusions 11 and are emitted by the two windings 2 is equivalent, so that the density of the magnetic induction lines is relatively uniform, and the uniformity of the density of magnetic leakage is favorably improved.
