ABSTRACT:
A rotary transmission device for a plurality of cables between to coaxial, utually restrictedly rotatable structures, especially for space satellites. One of said structures is formed with a cylindrical housing (9) while the other structure is formed with a hollow hub (8) coaxially extending through said housing (9). At least one support band (3) extends in the form of a spiral between the wall (10) of the housing (9) and the hollow hub (8) and is slidably supported at two plates (1, 2) forming the bottom and the cover of said housing (9). A plurality of individual electrical cables (6) are laid along the support band (3) in a slightly wavelike course, the cables (6) being fixed to the support band (3) at every second wave apex are retained at the other wave apices with radical and axial clearances with respect to the spiral.
