MAGNETIC CONNECTOR FOR ELECTRONIC DEVICE
First Claim
1. A connector insert comprising:
- a plurality of movable first contacts to make electrically conductive paths with a plurality of second contacts in a second connector when the connector insert is mated with the second connector, each of the movable first contacts biased by a corresponding one of a plurality of first springs; and
a magnetic element, the magnetic element made of ferromagnetic material to mate with a magnet in the second connector,wherein the magnetic element is formed around the plurality of movable contacts and the plurality of movable contacts are recessed relative to the magnetic element, such that a raised portion on the second connector fits within the magnetic element when the connector insert is mated with 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.
