Abstract (en)
A slip ring assembly (160) including a slip ring (164) and an electrical contact assembly (166). The slip ring (164) defines a circumference and an electrical contact groove (184) extending around the circumference of the slip ring (164). The electrical contact assembly (166) preferably includes a plurality of electrical contacts (187) spaced around the circumference of the slip ring (164) for engaging the electrical contact groove (184). In addition, an urging mechanism (234) is preferably associated with each of the electrical contacts (187) for urging the electrical contacts (187) toward engagement with the electrical contact groove (184). Finally, a wiper (244) is preferably associated with each of the electrical contacts (187) for extending within the electrical contact groove (184) to inhibit a fluid from passing through the electrical contact groove (184).
