ABSTRACT:
A slip ring wherein electric disconnection which may possibly arise from freezing of drops of condensed water is prevented with a simplified construction. The slip ring is of the type wherein electric connection between a fixed member and a movable member mounted for rotation relative to the fixed member is established by means of an annular conductive plate and a contact element mounted in mutual contact on one and the other of the fixed and movable members. The slip ring comprises an insulating cover mounted for rotation on the conductive plate and covering an annular face of the conductive plate. The cover has an opening formed therein through which the contact element is resiliently contacted with the conductive plate.
