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.
A housing for electronic circuits including a tubular shell in which are assembled frames each having the shape of a cylindrical sector containing the electronic circuits, wherein said housing is provided with means for fastening the frames within the tubular shell, said means being constituted at one end of said tubular shell by an internal radial flange which is integral with the internal wall of the tubular shell and to which the frames are attached at one end, and at the other end of the tubular shell by an expandable collar which is attached to said frames in such a manner as to produce expansion and locking within said tubular shell.
