Abstract:
1. A power adapter comprising: an adapter housing; a retractable prong coupled to a rotatable shaft within the housing such that the retractable prong can be pivoted from a retracted position in which the retractable prong is positioned adjacent to the housing, to a deployed position in which the retractable prong extends away from the housing, and can be inserted into an electrical outlet; a magnetic drive mechanism positioned within the housing and operatively coupled to rotate the retractable prong between the retracted position and the deployed position, the magnetic drive mechanism including a first and second driver magnet spaced a first axial distance apart, a first and second driven magnet attached to the rotatable shaft and spaced a second axial distance apart; an actuator operatively coupled to the magnetic drive mechanism to axially move the magnetic drive mechanism from a first position in which the first driver magnet is adjacent to the first driven magnet and the second driver magnet is displaced from the second driven magnet, to a second position in which the second driver magnet is adjacent to the second driven magnet and the first driver magnet is displaced from the first driven magnet, wherein when the magnetic drive mechanism moves from the first position to the second position the retractable prong is pivoted to the retracted position and when the magnetic drive mechanism moves from the second position to the first position the retractable prong is pivoted to the deployed position.
