ELECTROMAGNETIC CONNECTOR FOR ELECTRONIC DEVICE
First Claim
1. A connector comprising:
- a first contact;
an electromagnet positioned on the connector; and
a mechanical switch coupled to the electromagnet to control energization of the electromagnet, wherein the mechanical switch comprises a micro switch actuatable by a user,wherein the electromagnet is energizable to produce magnetic attraction with a magnetic element in a second connector and substantially maintain contact between the first contact and a second contact of the second connector in an electrically conductive relationship.

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.

8. A connector comprising:
-
a first contact; an electromagnet positioned on the connector; and a motion sensor coupled to the electromagnet to control energization of the electromagnet, wherein the electromagnet is energizable to produce magnetic attraction with a magnetic element in a second connector and substantially maintain contact between the first contact and a second contact of the second connector in an electrically conductive relationship, and wherein when the connector and the second connector are being mated, the motion sensor detects movement of the connector and allows the electromagnet to be energized, and a signal is passed via the first contact and the second contact to the motion detector causing the motion sensor to continue to allow the electromagnet to be energized. - View Dependent Claims (9, 10, 11, 12, 13, 14)
