Patent attributes
A power adapter has a cable port disposed on one side and a power conversion circuit to convert an input power from an alternating current (AC) power system to an output power used by a device coupled to the cable port. The power adapter further includes electrical contacts coupled to the power conversion circuit and locking columns disposed within a recessed cylindrical portion of a housing. An interchangeable head having prongs protruding from a surface couples to the electrical contacts of the power adapter to provide the input power to the power conversion circuit. A cylindrical body fits within the cylindrical housing in an assembly position, and includes locking tabs to engage the locking columns when the interchangeable head is rotated in a first direction into a first locking position and in a second direction into a second locking position.
