CA 2623692

An electrical plug (510) and receptacle (550) 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 (70), such as a laptop computer, to a power supply. The plug includes electrical contacts (520), which are preferably biased toward corresponding contacts (560) on the receptacle. The plug and receptacle each have a magnetic element (570, 530, 532). 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.

Cette invention concerne une fiche électrique (510) et une prise (550) utilisant la force magnétique d~un électroaimant pour maintenir un contact. La fiche et la prise peuvent servir d~éléments d~un adaptateur de courant destiné à raccorder un dispositif électronique (70), tel qu~un ordinateur portable, à une alimentation. La fiche comprend des contacts électriques (520), qui sont de préférence orientés vers des contacts correspondants (560) de la prise. La fiche et la prise comprennent chacune un élément magnétique (570, 530, 532). L~élément magnétique de la fiche ou la prise peut être un aimant ou un matériau ferromagnétique. L~autre élément magnétique est un électroaimant. Lorsque la fiche et la prise sont rapprochées, l~attraction magnétique entre l~électroaimant et son complément, soit l~aimant soit le matériau ferromagnétique, maintient les contacts en relation de conduction électrique.
