Abstract
An electrical power coupling includes a pair of power coupling parts, each having a base and a coupling portion that is movable relative to said base. Each coupling portion has first and second electrical contacts that are spaced laterally outboard, by respective first and second distances, from centers of the coupling portions. Magnetic elements attract the respective coupling portions to one another when the coupling portions are positioned closely to one another. Each coupling portion moves relative to its respective base to align the coupling portions with one another and establish electrical connections between the first electrical contacts and between the second electrical contacts. Optionally, at least two electrical contacts are arcuate or circular in shape.
