Abstract

A stackable connector interface with magnetic retention for electronic devices and accessories can allow power and data to be transferred between one or more stacked connectors. Each interconnected stackable connector includes one or more magnetic elements, which magnetic elements have poles arranged to facilitate mating with other stackable connectors. The magnetic elements provide a magnetic retention force that holds mated connectors in contact with each other. In some embodiments, the connectors include connection detection circuitry for determining whether the connectors are mated with other connectors, thereby allowing the connectors to prevent live contacts from being exposed at an unmated surface of the connectors. In some embodiments, routing circuitry is included to determine how signals should be transferred between the interconnected stackable connectors and/or corresponding devices.

First claim

What is claimed is:

1. A connector for wirelessly transferring data to an electronic device, the connector comprising:
a connector body, comprising:
a first magnet configured to align and magnetically couple a contact surface of the connector body with the electronic device in any one of multiple orientations by interacting with a second magnet of the electronic device, and
a transmission coil configured to wirelessly send data to a receiving system of the electronic device, the transmission coil being positioned relative the first magnet so that the interaction between the first and second magnets aligns the transmission coil with the receiving system when the connector body is magnetically coupled with the electronic device; and

circuitry configured to distinguish between at least a first orientation and a second orientation of the connector body with respect to the electronic device and to route a first signal between the connector body and the electronic device when the connector body is in the first orientation and route a second signal different from the first signal between the connector body and the electronic device when the connector body is in the second orientation.

2. The connector of claim 1 , wherein the first magnet is a ring magnet.

3. The connector of claim 2 , wherein the transmission coil is aligned with receiving coils of the receiving system when the connector body is magnetically coupled with the electronic device.

4. The connector of claim 3 , wherein the transmission coil is configured to transfer power inductively to the receiving coils.

5. The connector of claim 2 , wherein the transmission coil further comprises a coil-based repeater electrical system for routing signals to the receiving system.

6. The connector of claim 1 , wherein the connector body is a cylindrical connector body, a contact surface of the cylindrical connector body facilitating alignment of the cylindrical connector body with the electronic device in multiple orientations.

7. The connector of claim 1 , wherein the connector body is configured to wirelessly send both power and data to the receiving system of the electronic device.

8. The connector of claim 1 , wherein the electronic device is a first device and the connector body is a first connector body that includes a third magnet having poles arranged to align and magnetically couple the first connector body with a second connector body associated with a second device by interacting with a fourth magnet disposed within the second connector body.

9. The connector of claim 8 , wherein the first connector body includes another receiving system configured to receive signals wirelessly from a third device electrically coupled to the second connector body.

10. A method for wirelessly transferring data, the method comprising:
magnetically coupling a connector body with an electronic device, wherein interaction between a first magnet disposed within the connector body and a second magnet within the electronic device positions the connector body at a location on the electronic device in any one of multiple orientations in which a transmission coil within the connector body is aligned with a receiving coil within the electronic device; and
wirelessly transferring a first data signal between the connector body and the receiving coil when the connector body is in a first orientation with respect to the electronic device and transferring a second data signal, different from the first data signal, when the connector body is in a second orientation with respect to the electronic device using the transmission coil.

11. The method of claim 10 , further comprising wirelessly receiving data from the electronic device using an optical receiver.

12. The method of claim 11 , wherein magnetically coupling the connector body with the electronic device comprises placing a first surface of the connector body in direct contact with an exterior surface of the electronic device.

13. The method of claim 12 , wherein the connector body is a first connector body and wherein the method further comprises magnetically coupling a second connector body with a second surface of the first connector body, the second surface being opposite the first surface.

14. A peripheral device, comprising:
a connector body enclosing a first magnetic element and a wireless transmission coil, the first magnetic element being configured to interact with a second magnetic element disposed within an electronic device to magnetically couple the connector body to the electronic device in any one of multiple orientations in which the wireless transmission coil is aligned with a receiver coil of the electronic device; and
circuitry configured to distinguish between at least a first orientation and a second orientation of the connector body with respect to the electronic device and to route a first signal between the connector body and the electronic device when the connector body is in the first orientation and route a second signal different from the first signal between the connector body and the electronic device when the connector body is in the second orientation.

15. The peripheral device of claim 14 , further comprising an optical transceiver configured to both send data to and receive data from the electronic device when the wireless transmission coil is aligned with the receiver coil of the electronic device.

16. The peripheral device of claim 14 , further comprising:
a communication chip electrically coupled to the wireless transmission coil,
wherein the communication chip is in communication with the electronic device via the wireless transmission coil of the connector body.

17. The peripheral device of claim 14 , wherein the peripheral device is operable as a power adapter charger.

18. The peripheral device of claim 17 , wherein the connector body is configured to wirelessly transmit power from the transmission coil to the receiver coil by inductive wireless charging.
