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. A connector for a mobile communications device with a housing having a front surface, an end surface and a side surface, the connector comprising:

a recess proximate a corner of said housing;

a magnet coupling received in said recess and operable to form connections for communication with a control unit of the mobile communications device, by magnetic attraction with a plurality of other electronic devices, each adjacent one of said front surface, said end surface and said side surface, such that said magnetic attraction holds said mobile communications device and said plurality of other electronic devices in abutment.

2. The connector of claim 1, wherein said magnet coupling is operable to form a connection with another electronic device adjacent one of said front surface, said end surface and said side surface and maintain said connection during rotation of said another electronic device to a position adjacent a different one of said front surface, said end surface and said side surface.

3. The connector of claim 2, wherein said magnet coupling is operable to form a connection with said another electronic device adjacent said front surface and maintain said connection during rotation of said another electronic device to a position adjacent said side surface.
