Tangleproof Coupling

摘要

Along with Marshall Space Flight Center, Phase 2 Automation developed a unique rotary coupling capable of connecting a large number of electrical cables to a turntable without stressing the cables or tangling them. Device accommodates 246 cables and allows the turntable to rotate through an arc of 320 degrees. At extremes of rotation the cables remain loose enough so that they are not pulled taut and overstressed; a halfway rotation, the cables are not so loose that they tangle. The rotary connector was developed to carry electrical signals to and from a telescope platform on the satellite without employing a complex set of slip rings which are electrically noisy and could have caused signal interference.
