摘要

A transformer is built inside a winding cylinder with its primary winding linked to mains voltage and its secondary voltages linked to a diode bridge circuit and strip contacts on a printed circuit board to feed power to a plug socket fixed to rotate in a cable drum (10) with a cable outlet (69), a baseboard (70), a pocket for storing a cable plug (75) and an edge stiffener (88).
