Abstract: An apparatus for signal transmission between terminals (6, 8), between which at least one cable (10) is arranged, which is accommodated in an essentially circular cassette (K), to which ongoing cables can be connected at the terminals, and whose length is greater than the distance between the terminals. The cassette (K) comprises a rotor (R), which can rotate about its axis and bears at least one terminal, and a stationary stator (S), which likewise bears at least one terminal. The rotor (R) has a cylindrical hub (17), which runs in the axial direction of the cassette (K) and on which means are provided for fitting an intermediate base (16), which runs parallel to the cover face (18) and the base (19) of the accommodating area (15), is arranged at a distance from them, and divides the accommodating area (15) in a variable manner according to the height or width of the cable (10) to be inserted into the cassette into a smaller area (V) for the cable (10) and an empty area (L).

The cassette (K) comprises a rotor (R), which can rotate about its axis and bears at least one terminal, and a stationary stator (S), which likewise bears at least one terminal. The rotor (R) and stator (S) delimit a circular accommodating area (15) having a rectangular cross section, which serves the purpose of accommodating the cable (10) and has a cover face (18) and a base (19), running parallel thereto.

Abstract: A rotary joint with two housing parts (1, 2) rotatable with respect to each other, which are connected by a flexible flat conductor (10) that extends in spires within an interstice (11) of the housing parts (1, 2) and is attached at its end to a contact element (23), which connects a strand (27) of the flat conductor (10) with a circular conductor (5, 7) and which is arranged in a holder (21) in a housing part (1, 2). The contact element (23) of the rotary joint is a one-piece metal part having a surface (26) to which the strand (27) of the flat conductor (10) is permanently fixed, the contact element is attached to the circular conductor (5, 7) by crimping, and each contact element (23) is fixed within a holder (21) assigned to it.
