Magnetic component

Abstract

The present invention discloses a magnetic component. The magnetic component comprises a bobbin, a magnetic element and a winding. The bobbin comprises a center portion. The magnetic element is disposed on the bobbin and comprises a plurality of magnetic plates disposed around the center portion. The plurality of magnetic plates are separated to each other. Each magnetic plate comprises a magnetic plate main body, a center part, a first lateral part and a channel. The center part is disposed on one side of the magnetic plate main body adjacent to the center portion. The center part of each magnetic plate and the center part of the other magnetic plate are separated to each other. The first lateral part is disposed on one side of the magnetic plate main body away from the center portion. The channel is formed by a surface of the magnetic plate main body, the center part and the first lateral part collaboratively. The channel is disposed between the center part and the first lateral part. The winding is disposed on the magnetic element and disposed around the channel of each magnetic plate.

Claims

1. A magnetic component comprising: a magnetic sheet holder having a central portion; a magnetic component disposed on the magnetic sheet holder and comprising a plurality of magnetic sheets surrounding the central portion and spaced apart from each other, wherein each magnetic sheet comprises: a magnetic sheet body; a central post located on one side of the magnetic sheet body adjacent to the central portion, wherein the central post of each magnetic sheet is spaced apart from the central post of another magnetic sheet; a first side post located on one side of the magnetic sheet body away from the central portion; a channel formed by a surface of the magnetic sheet body, the central post, and the first side post, and located between the central post and the first side post; and a winding disposed on the magnetic component and wound around the channel of each magnetic sheet.

2. The magnetic component as claimed in claim 1, wherein the magnetic sheet holder further comprises a magnetic sheet holder body and a plurality of through holes, wherein the plurality of through holes are disposed through the magnetic sheet holder body and surrounding the central portion, wherein each magnetic sheet covers the corresponding through hole.

3. The magnetic assembly as claimed in claim 2, wherein the magnetic plate holder further comprises a plurality of protrusions, each protrusion being formed by protruding from a surface of the magnetic plate holder body and extending radially from the center portion toward the magnetic plate holder body and located between corresponding two perforations, and each protrusion comprising a recess with the opening of the recess facing away from the magnetic component, wherein at least a portion of the winding is disposed in the recess such that at least a portion of the winding protrudes through the recess to the outside of the magnetic assembly.

4. The magnetic assembly as claimed in claim 3, wherein the height of each of the protrusions is equal to the height of the magnetic sheet body.

5. The magnetic assembly as claimed in claim 3, wherein the magnetic plate holder further includes a plurality of fixing portions, each fixing portion being disposed on a surface of the magnetic plate holder body, and one end of each fixing portion being connected to the central portion and extending from the central portion toward the magnetic plate holder body in a radial direction.

6. The magnetic assembly as claimed in claim 5, wherein the magnetic plate holder further includes a plurality of second side posts surrounding one side of the magnetic plate holder body, each of the second side posts having a gap with an adjacent second side post, wherein each of the second side posts, the adjacent protrusion, the adjacent fixing portion and a portion of the magnetic plate holder body constitute a magnetic plate holder groove, wherein each magnetic plate is disposed in the corresponding magnetic plate holder groove.

7. The magnetic assembly as claimed in claim 6, wherein the height of each of the second side posts is equal to the thickness of the magnetic sheet body.

8. The magnetic assembly as claimed in claim 1, wherein the first side post of each magnetic sheet surrounds one side of the corresponding magnetic sheet body, and each magnetic sheet further includes a mounting groove located on the side of the corresponding magnetic sheet body and disposed adjacent to the corresponding first side post for mounting at least a portion of the winding, such that at least a portion of the winding protrudes from the outside of the magnetic assembly through the mounting groove.

9. The magnetic assembly as claimed in claim 1, wherein the height of the first side post of each magnetic sheet is equal to the thickness of the winding.

10. The magnetic assembly as claimed in claim 1, wherein the central post of each magnetic sheet is a fan-shaped structure and includes an inner ring portion and an outer ring portion, the inner ring portion being formed by an indentation at one end of the central post adjacent to the center portion, and the outer ring portion being located between the inner ring portion and the first side post.
