Magnetic connector for electronic device
First Claim
1. An apparatus for electrically connecting an electronic device to an electrical relation, comprising:
- a first connector having a first magnetic element and having at least one first contact electrically connected to the electronic device; and
a second connector positionable adjacent the first connector, the second connector having a second magnetic element and having at least one second contact electricallyconnected to the electrical relation,wherein the at least one first contact comprises a metallic contact extending from a first face of the first connector and biased relative to the first face,wherein magnetic attraction between the first and second magnetic elements substantially maintains the first and second contacts in an electrically conductive relationship,wherein the first and second connectors each comprise two axes of symmetry such that the first and second connectors couple together in only two orientations relative to one another, andwherein the at least one first and second contacts of the first and second connectors each comprise a pair of first path contacts on the connector for establishing a first path of electrical communication between the device and the relation, wherein the pairs of first path contacts form an electrically conductive relationship with one another regardless of which of the two orientations the connectors are magnetically coupled.

Abstract
An electrical plug and receptacle relying on magnetic force 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 or both of the plug and receptacle can be a magnet, which is preferably a permanent rare earth magnet although electromagnets may also be used. The magnetic element on the plug or receptacle that does not include a magnet is composed of ferromagnetic material. When the plug and receptacle are brought into proximity, the magnetic attraction between the magnet and its complement, whether another magnet or a ferromagnetic material, maintains the contacts in an electrically conductive relationship.
