    • PROBLEM TO BE SOLVED: To facilitate assembling work, reduce defectives, and reduce costs, by making up a rotor unit out of a rotor shaft and a plurality of conductive rings and insulating spacers, alternately stacked/disposed on the peripheral side thereof in an attachable/detachable manner, and disposing the conductive rings correspondently to slip electrodes. SOLUTION: Because a rotor unit 17 has a plurality of conductive rings 29 and insulating spacers 31 stacked/disposed in an attachable/detachable manner and the conductive rings 29 and the insulating spacers 31 are alternately fitted on the periphery of a rotor shaft 19, when conduction failure or insufficient insulation arises, it is only necessary to replace the conductive ring 29 or insulating spacer 31 in question with a new one. As for plating of the rotor unit, the conductive rings 29 can be previously dip-plated independently in large quantities in a plating tank. Wires of a fixed base unit are not deformed by insert molding. It is neither needed to prepare many kinds of dies. Respective components such as the conductive rings 29 can be put to common use.

    • PURPOSE:To manufacture a slip ring assembly with easy operation of injecting and finishing, by forming each slip ring element from a conducting material to whose inside surface of a lead welded, laminating such slip ring elements insulation rings made of epoxy resin alternately in a die in a cylindrical form, injecting epoxy resin into the laminate, and subjecting to a finishing process. CONSTITUTION:Slip ring elements 12 made of conductive material and insulation rings 13 of epoxy resin are alternately inserted in laminate in a die 10 in the form of a cylinder having the same inside diameter, for example 5.0mm, over the whole length, and into this laminate, epoxy resin is injected. This does not require inclusion molding of insulation rings 13, but merely a shaping process of a supporting shaft 14, so that injection of the epoxy resin can be done easily, and further because the outer surface of the molding is equipped with less surface unevenness, the finish trimming with machining and polishing do not require much labor. The die 10 used therein has no ring groove internally to allow use of a simple structure in the form of a cylinder having the same inside diameter over the whole length, which should suppress the cost for dies.
