Magnetically connectable grip and connector for electronics

Abstract

Finger grip and connector for portable electronics, in particular cell phones. The grip includes a metallic ring. The ring adheres to the back of a cell phone, or case. The grip includes a corresponding ring of magnets for a grip assembly to magnetically attach to the metal ring adhered to the cell phone. The grip design provides infinite rotation of the grip assembly relative to the phone for holding the phone in various positions. The grip provides a support for viewing content on the electronic device at different angles and orientations. The grip provides a means of magnetically attaching a cell phone to metallic surfaces, chargers, mounts, and other devices. The grip can allow for wireless charging, which is optimized and enabled by a relatively large open inner diameter of the metallic ring and corresponding magnets. The grip can retract to be less than 3 millimeters in total thickness.
