Abstract
Abstract An undersea communication cable system repeater housing and electronic circuits mounting structure includes a vessel having an electrical insulator covering an inside surface of the vessel. A heat conducting structure for mounting electronic circuits includes separable segments having surface areas contoured to match an inside surface of the electrical insulator. Electronic circuits are mounted on the heat conducting structure. The separable segments of the heat conducting structure are inserted into the vessel as a unit with resilient devices interposed between the segments for pressing the contoured surface areas into intimate contact with the inside surface of the electrical insulator.
