Abstract

Circuits, apparatus, and methods that provide a connector system that can supply both power and data to a mobile computing or other type of device using a single connection. Further examples also provide a power and data adapter that can provide power and data to a mobile computing device using a single cable. Further examples provide an easy disengagement when a cable connected to the connector is pulled. One such example provides a magnetic connector that uncouples without binding when its cord is pulled. Another example prevents power from being provided at a connector insert until the connector insert is placed in a connector receptacle.

First claim

What is claimed is:

1. A connector system comprising:
a first connector comprising:
a ferromagnetic attraction plate forming a raised guide having a first opening forming a recess;
a first pin to provide an electrical connection for a first power supply voltage;
a second pin to provide an electrical connection for a second power supply voltage, where the first pin and the second pin are located in the recess;
a third pin to transmit optical data, the third pin located in a second opening in a first corner of the ferromagnetic attraction plate;
a fourth pin to transmit optical data, the fourth pin located in a third opening in a second corner of the ferromagnetic attraction plate, the second corner diagonally opposite the first corner;
a fifth pin to receive optical data, the fifth pin located in a fourth opening in a third corner of the ferromagnetic attraction plate; and
a sixth pin to receive optical data, the sixth pin located in a fifth opening in a fourth corner of the ferromagnetic attraction plate, the fourth corner diagonally opposite the third corner.

2. The connector system of claim 1 wherein the first power supply voltage is a positive supply voltage and the second power supply voltage is a ground.

3. The connector system of claim 1 further comprising a fourth pin to provide an electrical connection for the first power supply voltage and a fifth pin to provide an electrical connection for the second power supply voltage.

4. The connector system of claim 1 further comprising a shield for the third pin to improve an optical connection.

5. The connector system of claim 1 further comprising a lens for the third pin to improve an optical connection.

6. The connector system of claim 1 further comprising:
a second connector to couple with the first connector, the second connector comprising:
a first pin to provide the electrical connection for the first power supply voltage;
a second pin to provide the electrical connection for the second power supply voltage; and
a third pin to provide an optical connection for optical data.

7. The connector system of claim 6 wherein the second connector comprises a magnet, where the magnet is attracted to the attraction plate such that the second connector is magnetically held to the first connector when the second connector and first connector are coupled.

8. The connector system of claim 7 wherein the second connector comprises a plurality of magnets having opposing polarities relative to each other, such that when the first connector is brought in close proximity to the second connector, magnetic field lines travel through the attraction plate of the first connector from one of the plurality of magnets in the second connector to another one of the plurality of magnets in the second connector, thereby increasing magnetic attraction between the first connector and the second connector.

9. The connector system of claim 1 wherein the first connector is a connector insert.

10. The connector system of claim 1 where the first pin and the second pin are located on a bottom surface of the recess.

11. The connector system of claim 1 wherein the first, second, third, fourth, fifth, and sixth pins are arranged so that a second connector may be mated to the first connector in two different orientations.

12. A connector system comprising:
a first connector comprising:
a raised guide surrounded by a recess;
a first pin to provide an electrical connection for a first power supply voltage;
a second pin to provide an electrical connection for a second power supply voltage, where the first pin and the second pin are located on the raised guide;
a third pin to transmit optical data, the third pin located in the recess;
a fourth pin to transmit optical data, the fourth pin located in the recess;
a fifth pin to receive optical data, the fifth pin located in the recess;
a sixth pin to receive optical data, the sixth pin located in the recess, where the third, fourth, fifth, and sixth pins are arranged to be symmetrical about a major axis and minor axis of the first connector; and
a magnet to be magnetically attracted to a magnetic element in a second connector such that the second connector is magnetically held to the first connector when the second connector and first connector are coupled.

13. The connector system of claim 12 wherein the first power supply voltage is a positive supply voltage and the second power supply voltage is a ground.

14. The connector system of claim 12 further comprising a fourth pin to provide an electrical connection for the first power supply voltage and a fifth pin to provide an electrical connection for the second power supply voltage.

15. The connector system of claim 12 further comprising a shield for the third pin to improve an optical connection.

16. The connector system of claim 12 further comprising a lens for the third pin to improve an optical connection.

17. The connector system of claim 12 further comprising:
a second connector to couple with the first connector, the second connector comprising:
a first pin to provide the electrical connection for the first power supply voltage;
a second pin to provide the electrical connection for the second power supply voltage; and
a third pin to provide an optical connection for optical data.

18. The connector system of claim 17 wherein the magnetic element of the second connector comprises an attraction plate comprising a ferro-magnetic material, where the magnet is attracted to the attraction plate such that the second connector is magnetically held to the first connector when the second connector and first connector are coupled.

19. The connector system of claim 18 wherein the first connector comprises a plurality of magnets having opposing polarities relative to each other, such that when the first connector is brought in close proximity to the second connector, magnetic field lines travel through the attraction plate of the second connector from one of the plurality of magnets in the first connector to another one of the plurality of magnets in the first connector, thereby increasing magnetic attraction between the first connector and the second connector.

20. The connector system of claim 17 wherein the magnetic element of the second connector comprises a second magnet, where the magnet of the first connector is attracted to the second magnet such that the second connector is magnetically held to the first connector when the second connector and first connector are coupled.

21. The connector system of claim 12 wherein the first connector is a connector receptacle.

22. The connector system of claim 12 where the first pin and the second pin are located on a top surface of the raised guide.

23. The connector system of claim 12 wherein the first, second, third, fourth, fifth, and sixth pins are arranged so that the second connector may be mated to the first connector in two different orientations.
