Abstract

A pinless power plug for receiving wireless power from a pinless power jack is disclosed The pinless power plug comprises at least one secondary coil for inductively coupling with a primary coil. The primary coil is associated with the pinless power jack. The primary coil is shielded behind an insulating layer. The pinless power jack comprises one or more magnetic anchors arranged around the at least one secondary coil in an annular configuration concentric with the at least one secondary coil. The one or more magnetic anchors are configured to magnetically couple with one or more magnetic snags in the pinless power jack. The one or more magnetic anchors are configured to magnetically couple with the one or more magnetic snags and maintain alignment between the at least one secondary coil and the primary coil.

Claims (24)

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, wherein the primary coil is associated with the pinless power jack, and wherein the primary coil is shielded behind an insulating layer; and

at least two magnetic anchors arranged around a perimeter of the at least one secondary coil in an annular configuration concentric and non-overlapping with the at least one secondary coil, wherein the at least two magnetic anchors are configured to magnetically couple with at least two magnetic snags in the pinless power jack.

2. The pinless power plug of claim 1 , wherein the at least two magnetic anchors are configured to magnetically couple with the at least two magnetic snags and maintain alignment between the at least one secondary coil and the primary coil.

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

4. The pinless power plug of claim 1 , wherein the at least two magnetic anchors are identical.

5. The pinless power plug of claim 1 , wherein the at least two magnetic anchors are not identical.

6. The pinless power plug of claim 1 , wherein the at least two magnetic anchors are such that, when magnetically coupled with the at least two magnetic snags, multiple discrete alignment angles are provided.

7. The pinless power plug of claim 1 , wherein the at least two magnetic anchors are such that the pinless power plug maintains alignment with the pinless power jack through 360 degrees of rotation about a central axis.

8. The pinless power plug of claim 1 , wherein the at least two magnetic anchors are arranged to have a configuration such that the at least two magnetic anchors align with the at least two magnetic snags when the pinless power plug is placed on the pinless power jack.

9. The pinless power plug of claim 1 , wherein one or more of the at least two magnetic anchors are permanent magnets.

10. The pinless power plug of claim 1 , wherein one or more of the at least two magnetic anchors are electromagnets.

11. 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; and

at least two magnetic snags arranged around a perimeter of the at least one primary coil in an annular configuration concentric and non-overlapping with the at least one primary coil, wherein the at least two magnetic snags are configured to magnetically couple with at least two magnetic anchors in the pinless power plug.

12. The pinless power jack of claim 11 , wherein the at least two magnetic snags are configured to magnetically couple with the at least two magnetic anchors and maintain alignment between the at least one primary coil and the secondary coil.

13. The pinless power jack of claim 11 , wherein the pinless power jack comprises at least two primary coils.

14. The pinless power jack of claim 11 , wherein the at least two magnetic snags are identical.

15. The pinless power jack of claim 11 , wherein the at least two magnetic snags are not identical.

16. The pinless power jack of claim 11 , wherein the at least two magnetic snags are such that, when magnetically coupled with the at least two magnetic anchors, multiple discrete alignment angles are provided.

17. The pinless power jack of claim 11 , wherein the at least two magnetic snags are such that the pinless power jack maintains alignment with the pinless power plug through 360 degrees of rotation about a central axis.

18. The pinless power jack of claim 11 , wherein the at least two magnetic snags are arranged to have a configuration such that the at least two magnetic snags align with the at least two magnetic anchors when the pinless power plug is placed on the pinless power jack.

19. The pinless power jack of claim 11 , wherein one or more of the at least two magnetic snags are permanent magnets.

20. The pinless power jack of claim 11 , wherein one or more of the at least two magnetic snags are electromagnets.
