Abstract
A downhole tool includes a slip ring assembly deployed radially between a shaft and a housing. The slip ring assembly may be configured as a stand-alone assembly and is further configured to provide a plurality of distinct electrical communication channels between the shaft and housing. These communication channels are suitable for transmitting electrical power and/or electronic data. Electrical connection is made between the housing and the slip ring assembly via a connector block that is fastened to a plurality of stator rings in the slip ring assembly. The connector block extends radially outward from the stator rings and physically engages an opening in the housing thereby rotationally coupling the stator rings to the housing.
