Abstract

There is disclosed magnetic connectors and electronic devices including such connectors. A connector may include a magnet rotatable about at least one axis of the magnet; wherein the magnet rotates to magnetically engage a magnet of another connector to form an electrical connection between the two magnets. A connector may also include a cylindrical magnet to magnetically engage a magnet of another connector; and a sleeve wrapped around at least part of the magnet, the sleeve comprising a contact for forming an electrical connection with a contact on the other connector. A connector may be adapted for selective connection with other connectors. A connector may be adapted such that a moveable magnet may move between an engaged position proximate a contacting surface of the connector and a disengaged position recessed from a contacting surface, wherein the moveable magnet is biased to the disengaged position.

Claims

1. An electronic device comprising:

a housing having walls defining an outer surface, said housing having a cavity proximate said outer surface;

processing electronics enclosed in an interior of said housing;

a magnet movably received in said cavity for magnetically holding an adjacent electronic device against said housing;

a flexible sleeve comprising a plurality of contacts, with a first end extending from said cavity into said interior of said housing in communication with said processing electronics and a second end wrapped at least partly around said magnet;

wherein said magnet is configured to be urged outwardly by magnetic attraction to an adjacent electronic device, thereby deforming said sleeve and moving said contacts of said sleeve to form connections with corresponding contacts of an adjacent electronic device.

2. The electronic device of claim 1, wherein said sleeve is a flexible flat cable.

3. The electronic device of claim 1, wherein said connections comprise a power connection.

4. The electronic device of claim 1, wherein each of said contacts of said sleeve carries a signal of a USB protocol.

5. The electronic device of claim 1, wherein said magnet is cylindrical.

6. The electronic device of claim 1, further comprising a shim interposed between said magnet and said sleeve for distributing force along said magnet.

7. The electronic device of claim 1, wherein said magnets are electrically isolated from one another by a plurality of insulating pads.

8. The electronic device of claim 1, wherein said magnet is at least partially received in an enclosure, and said enclosure comprises a guide structure, said first end of said flexible sleeve received through said guide structure.

9. A method of connecting a first electronic device with a second electronic device, comprising:

providing a magnetic contact assembly comprising a magnet within an enclosure and a flexible sleeve with a first end extending from the enclosure for electrical communication with processing electronics of the first device and a second end wrapped at least partly around said magnet, said sleeve having a plurality of contacts connected to an internal circuit of said first electronic device;

positioning said first electronic device adjacent said second electronic device and magnetically biasing said magnet against said flexible sleeve, thereby deforming said flexible sleeve and moving said contacts to form connections with corresponding contacts of said second electronic device.

10. The method of claim 9, wherein said forming connections comprises forming a data connection compatible with a universal serial bus (USB) protocol.

11. The method of claim 10, wherein said forming connections comprises forming at least eight connections.

12. The method of claim 10, wherein said forming connections comprises forming a power connection.

13. The method of claim 9, wherein said deforming said sleeve comprises pulling said flexible sleeve in a guide structure.

14. A connector assembly for an electronic device, comprising:

an enclosure for reception in said electronic device proximate an outer surface thereof;

a magnet in said enclosure, for magnetically holding another electronic device thereto;

a flexible sleeve comprising a plurality of contacts, with a first end extending from said enclosure for electrical communication with processing electronics of said electronic device, and a second end wrapped at least partly around said magnet;

wherein said magnet is configured to be urged outwardly by magnetic attraction to an adjacent electronic device, thereby deforming said sleeve and moving said contacts of said sleeve to form connections with corresponding contacts of an adjacent electronic device.

15. The connector of claim 14, wherein said contacts of said sleeve are configured to form a data connection with said another device.

16. The connector of claim 14, wherein each of said contacts of said sleeve carries a signal of a USB protocol.

17. The connector of claim 16, wherein said sleeve comprises at least eight contacts.

18. The connector of claim 14, wherein said contacts of said sleeve are configured to form a power connection with another device.

19. The connector of claim 14, further comprising a shim interposed between said magnet and said sleeve for distributing force along said magnet.

20. The connector of claim 14, wherein said enclosure comprises a guide structure, said first end of said flexible sleeve received through said guide structure.
