Abstract
The housing comprises a tubular vessel (1) which is rigid, heat-conducting, and closed in watertight manner at both ends, with electrical circuits being received in receptacles (2) which are rigid, heat-conducting, and pressed against the inside wall of the tubular vessel by annular split springs (8) disposed transversely between the receptacles which surround them and which press against them, and which by reaction are thrust toward the tubular vessel. Thin heat-conducting cushions (5) are inserted between the vessel and the receptacles. The receptacles are hinged on supports which bear against the spring, thereby enabling heat-generating circuits to be disposed in cavities (6) whose bottom lie close to the walls (3) via which the receptacles press against the tubular vessel. The invention is applicable, in particular, to repeater type equipment for undersea communications cables.
