Abstract

A rotary hub unit (U) for a transmission cable (C) includes a stationary hub (10) having a longitudinal axis (12). An angular transition cable portion (14) transmits a signal (16) between a first junction (18) and a second end junction (20). The first junction end (18) is perpendicular to the second junction end (20). A housing (22) is rotatably mounted about the longitudinal axis (12) and has an interior (24) adapted to receive a coiled portion (26) of transmission cable. The coil (26) is wrapped about the longitudinal axis (12), has a first end (28) mated with the angular transition second junction end (20), and an outer end (32) such that the rotary hub unit (U) permits limited movement of the outer end (32) of the coil (26).
