The invention which is particularly suitable for application in robots, concerns a device for making a preferably electrical connection between a central rotating cylindrical first part 4 with an outer wall 6 and a surrounding fixed second part 5 with an inner wall 7. These walls 6, 7 form a ring-shaped space 10 between them in which a ribbon cable 3 is laid. The cable 3 is attached at one end to the outer wall 6 of the first part 4 and can be wound up on this. In the space 10 the cable is turned through 180 degrees and the other end of the cable 3 is attached to the inner wall 7 of the second part 5. When the central first part 4 is turned the cable 3 is unrolled on the inner wall 7. According to the invention the outer wall 6 of the first part 4 is provided with guides 11 for the cable 3 intended to assist the unrolling of the cable 3 from the first part 4. <IMAGE> |
