MAGNETIC CONNECTOR FOR ELECTRONIC DEVICE
First Claim
1. A first connector comprising:
- a first plurality of electrical contacts, the first plurality of electrical contacts to mate with a second plurality of electrical contacts when the first connector couples to a second connector, wherein the first plurality of electrical contacts consisting of a central contact to convey a signal, two contacts to convey a power supply, one contact on each side of the central contact, and two contacts to provide a return path, one contact on each side of the central contact, wherein when the first connector couples to the second connector, the first and second plurality of electrical contacts define a corresponding plurality of electrical paths; and
a magnetic element, the magnetic element to mate with a plurality of magnets in the second connector that are proximally located and arranged in opposing polarities with respect to each other so that when the first connector is brought in close proximity to the second connector, magnetic field lines travel through the magnetic element 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.

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.

14. A first connector comprising:
-
a plurality of movable first contacts to make electrically conductive paths with a plurality of second contacts in a second connector when the first connector is mated with the second connector, each of the movable first contacts biased by one of a plurality of first springs; and a fixed magnetic element, the fixed magnetic element to mate with a plurality of magnets in the second connector that are proximally located and arranged in opposing polarities with respect to each other so that when the first connector is brought in close proximity to the second connector, magnetic field lines travel through the fixed magnetic element 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, wherein the fixed magnetic element surrounds the plurality of moveable contacts and a recessed face, such that a raised portion on the second connector fits within the fixed magnetic element when the first connector is mated with the second connector. - View Dependent Claims (15, 16, 17, 18, 19, 20)
