Abstract

An inductor device includes a first and a second inductor. First inductor includes plural first wires and a first connection member. Second inductor includes plural second wires and a second connection member. Part of first wires are winded/located at a first area, and part of first wires are winded/located at a second area. First and second areas are located on two opposite sides of inductor device. First connection member connects first wire located at first area and located at second area. Part of second wires are winded/located at first area, and part of second wires are winded/located at second area. One terminal of second connection member connects a terminal of second wire at an inner side of inductor device, and another terminal of second connection member is disposed outside inductor device. First and second inductors are symmetrical with respect to a center line of inductor device.

First claim

What is claimed is:

1. An inductor device comprising:
a first inductor comprising:
a plurality of first wires, wherein part of the first wires are winded and located at a first area, and part of the first wires are winded and located at a second area, wherein the first area and the second area are located on two opposite sides of the inductor device, respectively; and
a first connection member configured to connect the first wire located at the first area and the first wire located at the second area; and

a second inductor comprising:
a plurality of second wires, wherein part of the second wires are winded and located at the first area, and part of the second wires are winded and located at the second area; and
a second connection member, one terminal of the second connection member being configured to connect a terminal of the second wire located at an inside of the inductor device, and another terminal of the second connection member being disposed outside the inductor device;

wherein both the first inductor and the second inductor are symmetrical with respect to a center line of the inductor device, wherein the first connection member and the one terminal of the second connection member are respectively located at two sides of the inductor device.

2. The inductor device of claim 1 , wherein both the first inductor and the second inductor are mirror images with the center line as an axis.

3. The inductor device of claim 1 , wherein the center line of the inductor device is located between the first area and the second area.

4. The inductor device of claim 1 , wherein the first wires comprise:
a plurality of first sub-wires winded and located at the first area; and
a plurality of second sub-wires winded and located at the second area, wherein the first sub-wires are independent of the second sub-wires, and the first sub-wires and the second sub-wires are connected through the first connection member.

5. The inductor device of claim 1 , wherein the first inductor further comprises a terminal, wherein the terminal of the first inductor and the another terminal of the second connection member are respectively located on two sides of the inductor device.

6. The inductor device of claim 5 , wherein the first connection member and the another terminal of the second connection member are located on a same side.

7. The inductor device of claim 5 , wherein the first connection member and the terminal of the first inductor are located on a same side.

8. The inductor device of claim 1 , wherein the first wires and the second wires are arranged in an alternate manner in the first area or the second area.

9. The inductor device of claim 8 , wherein an arrangement of the first wires and the second wires in the first area or the second area is the first wire, the second wire, the first wire, and the second wire.

10. The inductor device of claim 1 , wherein the second connection member comprises a peripheral connection member, wherein the peripheral connection member is disposed along the first wires and the second wires.

11. The inductor device of claim 10 , wherein the second connection member comprises:
a first terminal configured to connect a terminal of the second wire located at the inside of the inductor device and at the first area; and
a second terminal disposed outside the inductor device.

12. The inductor device of claim 11 , wherein the second inductor further comprises:
a third connection member comprising:
a first terminal configured to connect a terminal of the second wire located at the inside of the inductor device and located at the second area; and
a second terminal disposed outside the inductor device.

13. The inductor device of claim 12 , wherein the second connection member comprises a second peripheral connection member, the third connection member comprises a third peripheral connection member, wherein each of the second peripheral connection member and the third peripheral connection member is disposed along the first wires and the second wires.

14. The inductor device of claim 13 , wherein the second peripheral connection member and the third peripheral connection member span the first wires and the second wires.

15. The inductor device of claim 14 , wherein the second peripheral connection member and the third peripheral connection member are symmetrical to one another with respect to the center line of the inductor device.

16. The inductor device of claim 15 , wherein the second peripheral connection member and the third peripheral connection member are mirror images with the center line as an axis.

17. The inductor device of claim 1 , further comprising:
a central connection member comprising:
a first terminal connected to a center of the first connection member; and
a second terminal disposed outside the inductor device.

18. The inductor device of claim 17 , wherein the central connection member is located on the center line of the inductor device.

19. The inductor device of claim 17 , wherein the center line of the inductor device is located between the first area and the second area.

20. The inductor device of claim 17 , wherein the central connection member spans the first wires and the second wires.
