Description
Technical field
The soft magnetic core of a kind of novel magnetic circuit of the utility model.
Background technology
The one sintering magnetic metal oxide that magnetic core is made up of various iron oxide mixture, by the magnetic flux density that can strengthen solenoid magnetic circuit in circuit, reduces copper loss, to increase electromagnetic intensity, improves photovoltaic conversion efficiency.All the time, magnetic core, as the important component part of magnetic element, receives much concern always.Particularly in recent years, along with the development of electronic component, also more and more higher to the requirement of magnetic core.But under the prerequisite met the demands, reduce costs, automation, environmental protection, develop new product, explore the development topic that new technology becomes current magnetic core manufacturing.
Traditional soft magnetic core structure is more, and as shown in Figure 1, magnetic core is E E type structure; As shown in Figure 2, magnetic core is EP type structure, also has the isostructural magnetic core of other EER, UF, RM, PQ, PM, Q, T and LP.Although existing magnetic core kind is abundant, and manufacturing process is simply ripe, cost is lower.But size is comparatively large, and more magnetic core center pillar interface is square, and wrapping post is all located at inside, makes troubles to coil winding, causes magnetic flux distribution uneven, magnetic core effectively utilize area little, and be unfavorable for heat radiation.
Summary of the invention
The soft magnetic core that the application provides that a kind of magnetic flux distribution is even, magnetic core effectively utilizes the large and good heat dissipation effect of area.
An a kind of soft magnetic core of novel magnetic circuit is provided in embodiment, comprises:
Base;
And several wrapping posts, wrapping post is cylindrical structure, and several wrapping posts are spaced apart to be vertically set on a face of base, and arrangement is point-blank.
Further, comprise 8 wrapping posts, the spacing between two wrapping posts of centre is greater than the spacing between all the other adjacent wrapping posts, and spacing between all the other adjacent wrapping posts is all equal.
Further, the spacing between two wrapping posts of centre is 1.3 ± 0.1mm, and the spacing between all the other adjacent wrapping posts is 1.0 ± 0.1mm.
Further, base is rectangular structure.
Further, the height of wrapping post is 0.8 ~ 0.9 times of base thickness.
Further, the height of wrapping post is 1.5 ± 0.1mm, and radius is 0.7 ± 0.05mm.
Further, the wrapping post at two ends is equal apart from the spacing at base two ends respectively.
Further, base and wrapping post are pressed one-body molded by NiZn ferrite powder.
According to the soft magnetic core of the novel magnetic circuit of above-described embodiment, due to several, column type wrapping post is spaced apart is vertically set on base, and arrangement point-blank, and wrapping post coiling is evenly distributed, namely make magnetic flux distribution even, what add magnetic core effectively utilizes area.Again because wrapping post is outside exposed, add the area of dissipation of magnetic core, namely improve radiating effect.

Embodiment
By reference to the accompanying drawings the utility model is described in further detail below by embodiment.
As shown in Figure 3, provide a kind of soft magnetic core of novel magnetic circuit in the utility model embodiment, magnetic core comprises base 1 and 8 wrapping posts 2.Base 1 and wrapping post 2 are pressed one-body molded by the NiZn ferrite powder that magnetic permeability is higher.
Base 1 is rectangular structure, is specifically of a size of 19.8mm*3.3mm*2mm.
8 wrapping posts 2 are cylindrical structure and equal and opposite in direction.8 wrapping posts 2 are spaced apart to be arranged on the 19.8mm*3.3mm face of base 1, and 8 wrapping posts 2 arrange point-blank.As shown in Figure 4, spacing L1 between two wrapping posts 2 of centre is greater than the spacing L2 between all the other adjacent wrapping posts 2, concrete, the spacing L1 between two wrapping posts 2 of centre is 1.3 ± 0.1mm, and the spacing L1 between all the other adjacent wrapping posts 2 is 1.0 ± 0.1mm.The height of wrapping post 2 is 0.8 ~ 0.9 times of base 1 thickness, concrete, and the height of wrapping post 2 is 1.5 ± 0.1mm.The wrapping post 2 at two ends is equal apart from the spacing L3 at base 1 two ends respectively, and spacing L3 is 0.65mm.
The soft magnetic core of the novel magnetic circuit that the present embodiment provides, be vertically set on base 1 because 8 column type wrapping posts 2 are spaced apart, and arrangement point-blank, wrapping post 2 coiling is evenly distributed, namely make magnetic flux distribution even, what add magnetic core effectively utilizes area, and namely magnetic core overall structure of the present utility model can be less than the magnetic core of hinge structure, and magnetic core effectively to utilize area and existing magnetic core to preserve consistent or larger, achieve the miniaturization of magnetic core.Again because wrapping post 2 is outside exposed, add the area of dissipation of magnetic core, namely improve radiating effect, reduce magnetic core temperature, thus make core loss lower, decrease the power loss of device.
More than applying specific case to set forth the utility model, just understanding the utility model for helping, not in order to limit the utility model.For the utility model person of ordinary skill in the field, according to thought of the present utility model, some simple deductions, distortion or replacement can also be made.
