Abstract
A rotary contact-connection assembly for electric cables contains an electrically non-conducting support crossed by a borehole. A first bearing is configured in the borehole and a second bearing is configured radially outside the borehole around the support. The bearings are configured axially relative to each other and to the borehole. Both bearings are radially continuously electrically conducting. An electrically conducting plug is pluggable into an axial bearing passage aperture of the first bearing. A first electrical conductor of a first cable is fixable to an outer race of the first bearing. A second electrical conductor of the first cable is connectable to a hookup muff situated within the second bearing. A first electrical conductor of a second cable is passable through the borehole of the support and is connectable to the plug. A second electrical conductor of the second cable is connectable to an outer race of the second bearing.
