Magnetic connector for electronic device
First Claim
1. A connector receptacle comprising:
- a recessed portion having a longer first axis and a shorter second axis, the recessed portion further having a bottom surface and sidewalls substantially orthogonal to the bottom surface;
at least three contact pins located in the recessed portion, extending above the bottom surface of the recessed portion, and not extending above a top of the sidewalls of the recessed portion, the at least three contacts to convey power and a return path, the at least three contacts arranged substantially in a line along the first axis; and
a first magnet positioned under the bottom surface of the recessed portion, and towards a first end of the first axis; and
a second magnet positioned under the bottom surface of the recessed portion, and towards a second end of the first axis, the first magnet and the second magnet having opposing polarities,wherein the recessed portion and the at least three contacts are arranged such that the connector receptacle is at least substantially symmetrical along the first axis and the second axis.

Abstract
An electrical plug and receptacle relying on magnetic force from an electromagnet to maintain contact are disclosed. The plug and receptacle can be used as part of a power adapter for connecting an electronic device, such as a laptop computer, to a power supply. The plug includes electrical contacts, which are preferably biased toward corresponding contacts on the receptacle. The plug and receptacle each have a magnetic element. The magnetic element on one of the plug or receptacle can be a magnet or ferromagnetic material. The magnetic element on the other of the plug or receptacle is an electromagnet. When the plug and receptacle are brought into proximity, the magnetic attraction between the electromagnet magnet and its complement, whether another magnet or a ferromagnetic material, maintains the contacts in an electrically conductive relationship.

9. A connector receptacle comprising:
-
a bottom surface having two opposing straight sides and two opposing curved sides, the two opposing curved sides at a first end and a second end of the connector receptacle; a sidewall surrounding the bottom portion and substantially orthogonal to the bottom portion; three contacts, each extending above the bottom surface and not above a top of the sidewall, the three contacts to form power and ground paths and arranged in a substantially straight line parallel to the two opposing straight sides of the bottom surface;
a first magnet under the bottom surface of the connector receptacle and towards the first end of the connector receptacle; anda second magnet under the bottom surface of the connector receptacle and towards the second end of the connector receptacle, the first magnet and the second magnet having opposing polarities. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A connector receptacle comprising:
-
a recessed portion defined by a bottom surface having two opposing straight sides and two opposing curved sides, the two opposing curved sides at a first end and a second end of the connector receptacle, and a sidewall surrounding the bottom portion and substantially orthogonal to the bottom portion, three contacts, each extending above the bottom surface and not above a top of the sidewall, the three contacts arranged to mate with contacts in a connector insert and to form power and ground paths, the three contacts arranged in a substantially straight line; a first magnet under the bottom surface of the connector receptacle and towards the first end of the connector receptacle; and a second magnet under the bottom surface of the connector receptacle and towards the second end of the connector receptacle, the first magnet and the second magnet having opposing polarities such that when the connector insert is brought in close proximity to the connector receptacle, magnetic field lines travel through a magnetic element of the connector insert from the first magnet in the connector receptacle to the second magnet in the connector receptacle. - View Dependent Claims (17, 18, 19, 20, 21, 22)
