Abstract
An electronic circuit housing primarily applicable to undersea transmission-line repeater equipment includes a pressure-resistant tubular steel shell provided with water-tight end walls and containing a cylindrical assembly of frames having the shape of cylindrical sectors. Each frame is attached at one end to a radial flange of the internal shell wall and at the other end to an expandable collar provided with sliding wedges and locked by expansion in the internal shell wall. The fastening system facilitates mounting and accurate centering of the frames within the tubular shell, thereby guaranteeing a constant thickness and therefore uniform thermal conductivity of the interface between frame and tubular shell.
