Device for transmitting signals between two terminals

Abstract

A device or transmitting signals between two terminals is indicated, where at least one of them is moveable with respect to the other. The terminals are connected by at least one line wound in turns, which is stored in an essentially circular cassette. The turns of the line are divided into an inner winding area and an outer winding area running in different directions, between which an approximately U-shaped reversing area is located. A one-piece ring-shaped guide (14) is located between the two winding areas and surrounds the reversing area of the turns. At least on the inside facing the inner winding area, the guide (14) has protrusions (15) that are distributed around the entire periphery and face radially out toward the center point (M), and which are offset with respect to each other in the peripheral direction. On the inside that faces the winding area, it has convex curved walls (16) between each two protrusions (15), where their minimum distance from the center point (M) of the guide (14) is larger than the minimum distance of the protrusions (15) from the same point. In the transition areas between the walls (16) and the protrusions (15), at least on the side that faces away from the direction of rotation of the guide (14) when the internal winding area increases, at least one nub (17) is located, which has a smaller minimum distance than the pertinent wall (16), but a larger minimum distance than the pertinent protrusion (15), from the center point (M) of the guide (14).
