Abstract

A magnetic connector for connecting various cables to a mobile electronic device includes a connector part in the mobile electronic device and a connector part attached to the cable. One of the connector parts includes a permanent magnet and the other connector part includes magnetic material or another magnet. The attractive magnetic force between the permanent magnet or the other magnet and the magnetic material keeps the connector parts into engagement. The magnets may themselves form the electrical contacts. The connector parts can also include magnetically operated switches.

Claims (24)

1. A device comprising a first connector part configured to interact with a second connector part disposed at the end of a cable to be connected to the device, wherein said first connector part includes a magnet that is magnetically attracted to magnetic material disposed on the second connector part and/or wherein magnetic material is disposed on said first connector part which is configured to magnetically attract a magnet disposed on the second connector part such that the magnetic force generated between the magnet and the magnetic material or between the two magnets is utilized for bringing the first connector part and the second connector part into engagement with each other thereby establishing an electrical connection between the cable and the device, and wherein the electrical connection is established by the magnet touching on the magnetic material.

2. The device according to claim 1 , wherein the first connector part includes a magnetically activated switch that is configured to assume one condition when the second connector part is connected to the first connector part and another condition when the second connector part is not connected to the first connector part.

3. The device according to claim 2 , wherein an electrical connection between the device and the cable can only be established in the position that the magnetically activated switch assumes when the first connector part is connected to the second connector part.

4. The device according to claim 1 , wherein said first connector part can connect to a third connector part and when said first and/or said third connector part include a magnet that is magnetically attractive to magnetic material disposed on the other connector part.

5. The device according to claim 4 , wherein a first electric routing is established when said second connector part is connected to said first connector part and wherein a second electric routing different from the first electric routing is established when said second connector part is connected to set third connector part.

6. The device according to claim 5 , wherein said different routing is established by a magnetic switch connected to said second connector part and said magnetic switch assuming the first position when said first connector part is connected to said second connector part and said magnetic switch assuming a second position when said second connector part is connected to set third connector part.

7. The device according to claim 1 wherein the second connector part is connected to a housing of a mobile electronic device.

8. The device according to claim 1 further comprising:

a third connector part arranged on said second connector part; and

a fourth connector part on said first connector part;

wherein said second connector part is arranged to attract said first connector part and to repulse said fourth connector part, and wherein said third connector part is arranged to attract said fourth connector part and to repulse said first connector part.

9. The device according to claim 7 , wherein said device is a mobile phone.

10. The device according to claim 7 , wherein said device is a battery charger.

11. The device according to claim 10 , further comprising a cable, wherein one end of the cable is coupled to said charger and the other end of said cable is attached to said connector part.

12. The device according to claim 1 wherein the first connector part is connected to an electrical conductor of a cable.

13. A method comprising:

providing a first connector part at a portion of a device; and

providing a second connector part disposed at an end of a cable, wherein the cable is configured to be connected to the device, wherein the first connector part is configured to interact with the second connector part, wherein the first connector part includes a magnet that is magnetically attracted to magnetic material disposed on the second connector part and/or wherein magnetic material is disposed on the first connector part which is configured to magnetically attract a magnet disposed on the second connector part such that the magnetic force generated between the magnet and the magnetic material or between the two magnets is utilized for bringing the first connector part and the second connector part into engagement with each other thereby establishing an electrical connection between the cable and the device, and wherein the electrical connection is established by the magnet touching on the magnetic material.

14. The method according to claim 13 further comprising:

providing a magnetically activated switch at the first connector part, wherein the magnetically activated switch is configured to assume one condition when the second connector part is connected to the first connector part and another condition when the second connector part is not connected to the first connector part.

15. The method according to claim 13 further comprising:

providing a third connector part on the second connector part; and

providing a fourth connector part on the first connector part;

wherein the second connector part is configured to attract the first connector part and to repulse the fourth connector part, and wherein the third connector part is configured to attract the fourth connector part and to repulse the first connector part.
