Abstract

An inductor according to one embodiment of the present invention comprises: a core part; a coil part having one or more coils which are wound around the midfoot of the core part and which have two ends; and a base which is arranged beneath the coil part and which supports at least a part of the outer circumferential surface of each of the one or more coils, wherein the base can comprise: a frame having a hollow hole, which is formed at the center thereof so as to include a longer shaft and a shorter shaft; and a support part having a plurality of support members protruding toward the outer circumferential surface, so as to encompass at least a part of the outer circumferential surface.

First claim

The invention claimed is:

1. A magnetic element comprising:
a coil-receiving unit, around which a wire forming a coil is wound and having therein a center hollow hole;
a core provided with a center leg, which passes through the center hollow hole, and a first outer leg and a second outer leg, disposed at a periphery of the center leg and configured to surround at least a portion of an outer side of the coil-receiving unit;
a first support configured to surround at least a portion of an outer side surface of the first outer leg and to be coupled to one side of the coil-receiving unit; and
a second support configured to surround at least a portion of an outer surface of the second outer leg and to be coupled to a remaining side of the coil-receiving unit, the remaining side facing the one side,
wherein each of the first support and the second support comprises:
a support member, extending in a first direction and positioned at a height at which a lower surface thereof is positioned higher than a lower surface of the core.

2. The magnetic element according to claim 1 , wherein the coil- receiving unit comprises:
a top part;
a bottom part; and
a middle part, disposed between the top part and the bottom part in a vertical direction and around an outer circumferential surface of which the wire is wound, and
wherein a lower surface of the top part is parallel to an upper surface of the bottom part.

3. The magnetic element according to claim 2 , wherein a height of the lower surface of the support member is equal to or higher than a height of the upper surface of the bottom part.

4. The magnetic element according to claim 3 , wherein at least a portion of the lower surface of the support member is disposed on an upper surface of an external substrate, having therein a hollow hole.

5. The magnetic element according to claim 2 , wherein the first support further comprises connection parts, which are provided at opposite ends of the support member in the first support and extend in a second direction toward one side of the bottom part, the one side facing an inner side surface of the support member.

6. The magnetic element according to claim 2 , wherein a planar shape of a first hollow hole, defined between the bottom part and an inner side surface of the first support, corresponds to a planar shape of the first outer leg.

7. The magnetic element according to claim 1 , wherein each of the first support and the second support has through holes in opposite ends thereof.

8. The magnetic element according to claim 7 , further comprising a pin disposed in each of the through holes.

9. The magnetic element according to claim 8 , wherein one end of the pin extends in a horizontal direction, and a remaining end of the pin is bent and extends in a vertical direction.
