Abstract

A coil component may include: a base board having an accommodation portion disposed therein and having conductive patterns disposed within the accommodation portion; an annular core disposed in the accommodation portion; and a laminated board laminated on the base board and having conductive patterns disposed on one surface thereof. The conductive patterns of the laminated board are connected to the conductive patterns of the base board to form a coil.

Claims

1. A coil component comprising:

a base board having an accommodation portion and conductive patterns disposed within the accommodation portion;

a core disposed in the accommodation portion, wherein the core has a gap which is a cut portion of the core and the base board includes an insertion protrusion formed within the accommodation portion to fix a position of the core gap; and

a laminated board laminated on the base board and having conductive patterns disposed on one surface thereof,

wherein the conductive patterns of the laminated board are connected to the conductive patterns of the base board to form a coil.

2. A coil component comprising:

a base board having an accommodation portion and conductive patterns disposed within the accommodation portion;

a core disposed in the accommodation portion, wherein the core has a gap which is a cut portion of the core; and

a laminated board laminated on the base board and having conductive patterns disposed on one surface thereof,

wherein the conductive patterns of the laminated board are connected to the conductive patterns of the base board for form a coil, and

wherein the base board includes at least one core guide defining an insertion position of the core within the accommodation portion, and an insertion protrusion protrudes from the core guide and is inserted into the gap of the core.

3. The coil component of claim 2, wherein the core guide is disposed on the corner between a side wall of the accommodation portion and a bottom surface of the accommodation portion.

4. The coil component of claim 3, wherein the core guide has an ‘

L’

shape.

5. The coil component of claim 2, wherein the core guide protrudes from a side wall of the accommodation portion or a bottom surface of the accommodation portion.

6. The coil component of claim 5, wherein the core guide has a shape having a width that reduces towards an upper end thereof.

7. The coil component of claim 2, wherein a plurality of core guides are disposed to be spaced apart from one another at equal intervals.

8. The coil component of claim 2, wherein the core guide protrudes between the conductive patterns radially disposed on the accommodation portion.

9. A coil component comprising:

a base board having an accommodation portion and conductive patterns disposed within the accommodation portion;

a core disposed in the accommodation portion, wherein the core has a gap which is a cut portion of the core;

a barrier inserted into the gap of the core and coupled within the accommodation portion to fix the core to the accommodation portion; and

a laminated board laminated on the base board and having conductive patterns disposed on one surface thereof,

where the conductive patterns of the laminated board are connected to the conductive patterns of the base board to form a coil.

10. The coil component of claim 9, wherein the base board includes an insertion recess within the accommodation portion and allowing the barrier to be coupled thereto.

11. A coil component comprising:

a board assembly having an accommodation portion and conductive patterns disposed on an inner surface of the accommodation portion; and

a core embedded in the accommodation portion,

wherein at least one core guide is disposed within the accommodation portion to secure a space by which the core is separated from the conductive patterns; and

wherein the core has a gap which is a cut portion of the core, and the board assembly includes an insertion protrusion formed within the accommodation portion to fix a position of the core gap.

12. The coil component of claim 11, wherein the board assembly comprises:

a base board having the accommodation portion disposed therein; and

a laminated board laminated on the base board to embed the core therein.

13. The coil component of claim 11, wherein the board assembly includes at least one conductive pattern having a coil shape wound around the core.

14. The coil component of claim 13, wherein the board assembly includes at least one external terminal disposed on any one surface thereof, electrically connected to the conductive patterns and electrically and physically connected to the outside.

15. The coil component of claim 11, wherein the interior of the accommodation portion is filled with an insulating material.
