As shown in Fig. 2, the magnetic element 2 includes two front and rear plate cores 210, a columnar core 220, at least one winding group 23A, and upper and lower plate cores 240. The columnar core 220 is located between the two plate cores 21A, and the winding group 230 is wound around the column cores 220. Further, the winding group 230 of the present embodiment is electrically connected to the circuit board 3 through its both ends TE1, TE2. Here, some of the components of the magnetic component 200 of FIG. 2 have been assembled, and the plate-shaped magnetic core 240 located above the cylindrical core 220 is illustrated as being decomposed with other components for convenience of explanation. As shown in Fig. 2, each of the plate-like magnetic cores 2, 1 is provided with an opposite surface S1 and a surface S2, wherein the surfaces w, S2 are, for example, the upper and lower surfaces of the plate-like magnetic core 210, respectively. The plate cores 24 are disposed on the surface S1 and the surface S2 of the plate core 210, respectively. In the present embodiment, the width Xb and the thickness χ3 of the upper and lower plate-shaped cores 240 are, for example, 15 mm (mm), 2 mm, and 2.5 mm, respectively, but the creation is not limited thereto. In the present embodiment, the magnetic element 200 is, for example, a choke or an inductor. Further, the magnetic element 2 can be used as a power factor correction (PFC) choke, a transformer M439247 secondary inductance, a differential mode (diff_ce m〇de) inductance or a common mode (common) Mode) Inductance, etc. In addition, the material of the plate cores 21, 240 and the columnar core 220 may be a ferrite material, iron or a low magnetic loss material. Ferrite materials include NiZn ferrite or Mn_Znferrite. Further, the plate cores 21G, 24G and the columnar core 22G can be _ magnetic core magnetic (_ coffee), Ming Shi Xi iron core (_ustc〇re), amorphous magnetic powder core (FAA ) or a curved core, but the creation is not limited to this. 3A is a top plan view of the magnetic element 2 图 of FIG. 2 without the plate-shaped core 24 〇 and the winding group 23 ,, and FIG. 3B is the magnetic element of FIG. 2 · without the plate-shaped magnetic S 24 〇 and winding A front view of the group 23〇. Referring to FIG. 2 and FIG. 3A, the columnar core 220 has opposite side surfaces: and the columnar magnetic anger 220 is connected to the plate-shaped magnetic foot and the 2 〇 through the side surfaces S3 and S4. In the present embodiment, the plate core 210 and the columnar core 22 can be integrated. Further, the side surfaces S3 and S4 of the columnar core 220 are the same two surfaces of the same shape, and the shapes of the side surfaces S3 and S4 may be square (as indicated by the hatched portion of 3B). In addition, the surface S1 of the plate core 21〇 and the surface S2 are substantially perpendicular to the side surface of the columnar core 22〇. Next, referring to Figs. 3A and 3B, it should be noted that the areas of the surfaces S1 and S2 of 2H) are substantially half the area of the columnar core, the surface S3 or S4 of 24 。. That is, the area of the side surface S4 of the target is twice the area of the surface S1 or the surface & For example, the length of the surface of the plate-shaped core 210 of Fig. 3A is 20 mm and 2.5 mm, respectively, with the angle of X 5 , and the length π of the side surface of the column 20 of Fig. 3B is The width χ 8 is, for example, (7) millimeters.

It is worth mentioning that since the shape of the plate core 21G of the present embodiment is symmetrical to the side surfaces S3 and S4 of the columnar magnetic anger 220, the number of magnetic lines of force after the magnetic line 3 passes through the side surface 33 is divided into half. 'And the direction of the magnetic lines B1, B2 is the surface si and § 2 of the plate-shaped core 210. For example, as shown in FIG. 2 and FIG. 2, about half of the magnetic lines of force B1 will sequentially pass through the side surface of the cylindrical core 22G, the surface S1 of the front plate-shaped core 210, and the upper plate-shaped core 24 The surface s 1 of the 板, rear plate-shaped core (4) and the side surface S4 of the columnar core 220 are returned to the cylindrical core 22A. The other-half magnetic field line B2 is sequentially passed through the side surface S3 of the cylindrical core 22, the front plate-shaped magnetic g 21 〇 from the %, the lower plate-shaped magnetic anger 240, and the surface of the rear plate-shaped magnetic core 210. S2 and the side surface S4 of the columnar core 22'' are returned to the columnar core 22'. In other words, the surface S3, S4 of the cylindrical core 22 〇 M439247 and the surface Sb S2 of the slab core correspond to the wear of the magnetic flux ,, and the sum of the magnetic fluxes of the surface 8 S2 is substantially equal to the side surface. The magnetic flux of S3 and S4. It should be noted that in the present embodiment, since the areas of the surfaces S1 and S2 of the plate-like magnetic body 210 are substantially the column core, the side surface S3 of the 240 is half, that is, the surface Si and S2. The area and substantially equal to the side of the dendritic core 240 (four) or to. Therefore, even if the magnetic flux of the surface quality 3 = surface S2) is half of the side surface S3 (or the side surface S4) @, since the area of the surface S1 (or the surface S2) of the plate core, 210 is also columnar, 240 The side surface S3 (or the half surface of the side surface (4), so the whole is the same, the magnetic flux density on the side surfaces S3, S4 and the surfaces S1, S2 are the same. Fig. 3C is the magnetic element 2 of Fig. 2 without the plate shape 2, FIG. 3B and FIG. 3C, the plate core 210 of the present embodiment has two opposite surfaces S5, and each surface S5 is connected to the surface. S1 and surface illusion. In addition, as shown in Fig. 3b, the surface S5 has four curved sides c. In this embodiment, the curved side c can be a quarter-arc material, a circle The center of the arc C1 is the projection point 0 of the vertex of the side surface S3 on the surface S5, and the radius Γ of the circular arc C1 is substantially half the length Χ7 of the side surface S3 of the cylindrical core 240. The length of the side surface S3 For example, the radius Γ7 and the width χ8 are both 1 mm, and the radius Γ of the arc C1 is, for example, 5 mm. In addition, the length Χ9 of the plate-shaped core 210 of Fig. 3C is, for example, 20 mm. The thickness χ6 of the columnar core 22〇 is, for example, 10 mm. In the present embodiment, the circular arc design described above can guide the traveling direction of the magnetic field line b of FIG. 2 in order to make the magnetic lines m and b2 evenly distributed. On the surfaces S1 and S2 of the plate-like magnetic core 21A. In addition, the circular arc-shaped "details" form a recess 212 on the side of the magnetic member 200 to expose the portion of the plate-shaped magnetic core 21G. The wire group 22(), thereby contributing to the heat dissipation of the winding group 22〇, thereby improving the fine stability of the magnetic component 4, the arc-shaped design also facilitates the production of the plate-shaped magnetic core 21〇. Please continue to refer to FIG. It is worth mentioning that the structure of the magnetic component 200 of the present embodiment facilitates winding the winding group top button around the magnetic element 2 位于 between the front and rear plate-shaped cores 210, and then the front and rear plates.
