Abstract

Claims (23)

1. A pinless power plug for receiving wireless power from a pinless power jack, the pinless power plug comprising:

at least one secondary coil for inductively coupling with a primary coil;

a first magnet, having an annular shape, arranged around a perimeter of the at least one secondary coil concentric and non-overlapping with the at least one secondary coil, wherein the first magnet is configured to magnetically couple with a second magnet in the pinless power jack; and

a third magnet spaced away from and outside of the first magnet, wherein the third magnet is configured to magnetically couple with a fourth magnet in the pinless power jack at a particular orientation.

2. The pinless power plug of claim 1 , wherein the third magnet is configured to limit a rotation of the pinless power plug around a central axis of the pinless power jack.

3. The pinless power plug of claim 1 , wherein the first magnet is configured to magnetically couple with the second magnet and maintain alignment between the at least one secondary coil and the primary coil.

4. The pinless power plug of claim 1 , wherein the pinless power plug comprises at least two secondary coils.

5. The pinless power plug of claim 1 , wherein the first magnet is such that, when magnetically coupled with the second magnet, multiple discrete alignment angles are provided.

6. The pinless power plug of claim 1 , wherein the first magnet is such that the pinless power plug maintains alignment with the pinless power jack through 360 degrees of rotation about a central axis.

7. The pinless power plug of claim 1 , wherein the first magnet is arranged to have a configuration such that the first magnet aligns with the second magnet when the pinless power plug is placed on the pinless power jack.

8. The pinless power plug of claim 1 , wherein the first magnet is a permanent magnet or electromagnet.

9. The pinless power plug of claim 1 , wherein the primary coil is shielded behind an insulating layer.

10. A pinless power jack for transmitting wireless power to a pinless power plug, the pinless power jack comprising:

at least one primary coil, shielded on a side of an insulating layer, for inductively coupling with a secondary coil associated with the pinless power plug, wherein the secondary coil is on a different side of the insulating layer;

a first magnet, having an annular shape, arranged around a perimeter of the at least one primary coil concentric and non-overlapping with the at least one primary coil, wherein the first magnet is configured to magnetically couple with a second magnet, having an annular shape, in the pinless power plug; and

a third magnet spaced away from and outside of the first magnet, wherein the third magnet is configured to magnetically couple with a fourth magnet in the pinless power plug at a particular orientation.

11. The pinless power jack of claim 10 , wherein the third magnet is configured to limit a rotation of the pinless power jack around a central axis of the pinless power plug.

12. The pinless power jack of claim 10 , wherein the first magnet is configured to magnetically couple with the second magnet and maintain alignment between the at least one primary coil and the secondary coil.

13. The pinless power jack of claim 10 , wherein the pinless power jack comprises at least two primary coils.

14. The pinless power jack of claim 10 , wherein the first magnet is such that, when magnetically coupled with the second magnet, multiple discrete alignment angles are provided.

15. The pinless power jack of claim 10 , wherein the first magnet is such that the pinless power jack maintains alignment with the pinless power plug through 360 degrees of rotation about a central axis.

16. The pinless power jack of claim 10 , wherein the first magnet is arranged to have a configuration such that the first magnet aligns with the second magnet when the pinless power plug is placed on the pinless power jack.

17. The pinless power jack of claim 10 , wherein the first magnet is a permanent magnet or electromagnet.
