Abstract

An inductor includes a base and a cup core. The base, which is able to be adapted to be used with the cup core, includes a plurality of first embedding parts and a plurality of second embedding parts. The first embedding parts and the second embedding parts have different shapes and are disposed around the base by turns. The cup core has at lease two sidewalls connected to each other, and a protruding block is disposed in the corner between two adjacent sidewalls for allowing the second embedding parts of the base to be matched therewith. Besides, a recess is disposed on each sidewall for allowing the first embedding parts of the base to be matched therewith.

Claims

1. An inductor base adapted to be used with a cup core, comprising:

a plurality of first embedding parts disposed around the base; and

a plurality of second embedding parts disposed around the base, wherein each of the first embedding parts and each of the second embedding parts are alternately disposed and shapes of the first embedding parts are different from those of the second embedding parts.

2. The inductor base of claim 1, wherein the cup core has at least two sidewalls connected to each other, a protruding block formed at a corner between each two adjacent sidewalls for allowing the second embedding parts of the inductor base to be matched therewith, and a recess formed on each of the sidewalls for allowing the first embedding parts of the inductor base to be matched therewith.

3. The inductor base of claim 2, wherein a shape of each of the first embedding parts corresponds to that of the corresponding recess.

4. The inductor base of claim 2, wherein each of the recesses is a rectangular concave space.

5. The inductor base of claim 1, wherein the inductor base has an octagonal shape with two opposite horizontal sides, two opposite vertical sides, and four slant sides connecting the horizontal sides and the vertical sides.

6. The inductor base of claim 5, wherein the first embedding parts are disposed at the horizontal sides and the vertical sides, respectively and the second embedding parts are disposed at the slant sides, respectively.

7. The inductor base of claim 1, wherein each of the first embedding parts has a rectangular shape and each of the second embedding parts has a trapezoidal shape.

8. The inductor base of claim 1, further comprising:

a plurality of pins located at the second embedding parts.

9. An inductor, comprising:

a base, which includes a plurality of first embedding parts and a plurality of second embedding parts disposed by turns, wherein a shape of each of the first embedding parts are different from that of each of the second embedding parts; and

a cup core having at least two sidewalls connected to each other, wherein a protruding block is disposed at a corner between each two adjacent sidewalls for allowing the second embedding parts of the base to be matched therewith and a recess is formed on each of the sidewalls for allowing the first embedding parts of the base to be matched therewith.

10. The inductor of claim 9, further comprising a core and a coil wound around the core, wherein the cup core has four sidewalls connected to each other so as to form an accommodation space for allowing the core and the coil to be disposed therein.

11. The inductor of claim 9, wherein the base has an octagonal shape with two opposite horizontal sides, two opposite vertical sides, and four slant sides connecting the horizontal sides and the vertical sides.

12. The inductor of claim 11, wherein the first embedding parts are disposed at the horizontal sides and the vertical sides, respectively and the second embedding parts are disposed at the slant sides, respectively.

13. The inductor of claim 9, wherein the base further comprises a plurality of pins located at the second embedding parts for connecting with terminals of the coil.

14. The inductor of claim 9, wherein a shape of each of the first embedding parts corresponds to that of the corresponding recess.

15. The inductor of claim 9, wherein each of the first embedding parts has a rectangular shape and each of the second embedding parts has a trapezoidal shape.

16. The inductor of claim 9, wherein each of the recesses is a rectangular concave space.
