Abstract

A wireless power receiver can include a magnetic substrate and a coil configured to wirelessly receive power. The coil can be formed as a conductive layer on the magnetic substrate. A connecting unit can be disposed in a receiving space of the magnetic substrate and can be connected to the coil unit.

First claim

What is claimed is:

1. A wireless power receiver, comprising:
a magnetic substrate comprising a first receiving space and a second receiving space;
a coil on the magnetic substrate;
a first connection terminal connected to an outer end of the coil;
a second connection terminal connected to an inner end of the coil; and
a connecting unit comprising a third connection terminal connected to the first connection terminal, and a fourth connection terminal connected to the second connection terminal,
wherein the first connection terminal and the third connection terminal overlap the first receiving space in a vertical direction perpendicular to the magnetic substrate,
wherein the second connection terminal and the fourth connection terminal overlap the second receiving space in the vertical direction, and
wherein the connecting unit comprises:
a wiring layer connected to the third connection terminal and the fourth terminal.

2. The wireless power receiver of claim 1 , wherein the first receiving space is positioned outside the coil, and
wherein the second receiving space is positioned inside the coil.

3. The wireless power receiver of claim 1 , wherein the wiring layer is connected to a receiving circuit, and
wherein the receiving circuit is disposed outside the first receiving space and the second receiving space.

4. The wireless power receiver of claim 1 , wherein the connecting unit comprises:
a first region on which the third connection terminal is disposed;
a second region on which the fourth connection terminal is disposed; and
a third region connecting the first region and the second region,
wherein the third region overlaps the coil in the vertical direction.

5. The wireless power receiver of claim 4 , wherein the connecting unit comprises:
a fourth region not overlapping the magnetic substrate in the vertical direction.

6. A wireless power receiver, comprising:
an adhesive layer comprising a receiving space;
a coil on the adhesive layer;
a first connection terminal connected to an outer end of the coil;
a second connection terminal connected to an inner end of the coil; and
a connecting unit overlapping the receiving space in a vertical direction perpendicular to the adhesive layer,
wherein the connecting unit comprises:
a third connection terminal connected to the first connection terminal;
a fourth connection terminal connected to the second connection terminal; and
a wiring layer connected to the third connection terminal and the fourth terminal.

7. The wireless power receiver of claim 6 , wherein the receiving space extends from inside the coil to outside the coil.

8. The wireless power receiver of claim 6 ,
wherein the wiring layer is connected to a receiving circuit, and
wherein the receiving circuit is disposed outside the first receiving space and the second receiving space.

9. The wireless power receiver of claim 6 , wherein the connecting unit comprises:
a first region on which the third connection terminal is disposed;
a second region on which the fourth connection terminal is disposed; and
a third region connecting the first region and the second region,
wherein the third region overlaps the coil in the vertical direction.

10. The wireless power receiver of claim 9 , wherein the connecting unit comprises:
a fourth region not overlapping the adhesive layer in the vertical direction.

11. A wireless power receiver, comprising:
a magnetic substrate comprising a first receiving space and a second receiving space;
a coil on the magnetic substrate;
a first connection terminal connected to one end of the coil;
a second connection terminal connected to an other end of the coil; and
a connecting unit comprising a third connection terminal connected to the first connection terminal, and a fourth connection terminal connected to the second connection terminal,
wherein the first connection terminal and the third connection terminal is disposed corresponding to the first receiving space,
wherein the second connection terminal and the fourth connection terminal is disposed corresponding to the second receiving space,
wherein the connecting unit comprises a wiring layer connected to the third connection terminal and the fourth terminal.

12. The wireless power receiver of claim 11 , wherein the first receiving space is positioned outside the coil, and
wherein the second receiving space is positioned inside the coil.

13. The wireless power receiver of claim 11 , wherein the wiring layer is connected to a receiving circuit, and
wherein the receiving circuit is disposed outside the first receiving space and the second receiving space.

14. The wireless power receiver of claim 11 , wherein the connecting unit comprises:
a first region on which the third connection terminal is disposed;
a second region on which the fourth connection terminal is disposed; and
a third region on the coil.

15. The wireless power receiver of claim 14 , wherein the connecting unit comprises:
a fourth region which is not disposed on the magnetic substrate.

16. A wireless power receiver, comprising:
an adhesive layer comprising a receiving space;
a coil on the adhesive layer;
a first connection terminal connected to one end of the coil;
a second connection terminal connected to an other end of the coil; and
a connecting unit disposed corresponding to the receiving space,
wherein the connecting unit comprises:
a third connection terminal connected to the first connection terminal;
a fourth connection terminal connected to the second connection terminal; and
a wiring layer connected to the third connection terminal and the fourth terminal.

17. The wireless power receiver of claim 16 , wherein the receiving space extends from inside the coil to outside the coil.

18. The wireless power receiver of claim 16 , wherein the wiring layer is connected to a receiving circuit, and
wherein the receiving circuit is disposed outside the first receiving space and the second receiving space.

19. The wireless power receiver of claim 16 , wherein the connecting unit comprises:
a first region on which the third connection terminal is disposed;
a second region on which the fourth connection terminal is disposed; and
a third region on the coil.

20. The wireless power receiver of claim 19 , wherein the connecting unit comprises:
a fourth region which is not disposed on the adhesive layer.
