US Patent 7641476 Rotatable magnetic electrical connector

A rotatable quick disconnect electrical connector assembly is provided. The assembly includes a male component and a female component, which have a mating fit together and which have an electrical connection when in mating contact. The connection is further enhanced by magnetic attraction, one of either the male or female components having a magnetic material and the other having a magnet-sensitive material. Each of the male and female components has a generally circular cross-section, to permit relative rotation through unlimited degrees in clockwise and counterclockwise directions. The components may be made separately. A system of such connectors is also provided (e.g. for displays).
