Abstract: Metal frame constructed from sections of the same structural element. This structural element is obtained by folding a metal strip to define a substantially square or rectangular cross-section first part (14) and an L-shape cross-section second part (16) and a space is formed between an edge (18) of the metal strip and a fold (19) defining the boundary between said first and second parts so as to define a slot (20) enabling insertion of panel mounting means. Application to the manufacture of metal cabinets for industrial electrical or electronic equipment.

Abstract: A circuit card frame comprising one-piece molded panels and sidewalls. The panels have U-shaped tenons adapted to be inserted in openings in the sidewalls and slid into place along locating tongues and ridges disposed in the openings. The panels have elastic tongues adapted to be deflected along ramps disposed between pairs of tenons at the ends of the panels when the panels are slid into place, the free edge of the elastic tongues abutting an end of the ramps to lock the panels on the sidewalls. A mounting clip may be provided for holding a mothercard to a panel.
