Abstract: A card cage for mounting circuit boards comprises lateral panels and an electrically connecting panel extending between the lateral panels. Opposed sets of two spaced rails span the lateral panels and support extruded grille units substantially transverse to the connector panel and the lateral panels to define a cavity for receiving the circuit boards. A plurality of guides formed integrally with each grille unit receive edges of circuit boards inserted in the cavity. Each set of rails and associated grille units define a grille structure of the card cage. A method for forming a grille structure for use in a card cage comprises the steps of forming a support member and support rails. Forming the support member includes extruding a metal piece with a planar portion and a plurality of elongated, U-shaped members carried by the planar portion, cutting the metal piece transverse to the U-shaped members and forming a connecting surface.

Abstract: A front panel for mounting a printed circuit board in a card cage. A central frame is formed with an integral extrusion from which integral printed circuit board mounting brackets can be formed on one surface of the central frame. Ejector assemblies mount at each end of the central frame and include an extruded mounting bracket that attaches to the central frame, an extruded ejection handle with legs that straddle the mounting frame and a solid handle portion with a pivot that mounts to a solid pin captured in the assembled structure. Rotating the extraction handle causes the legs to bear against the card cage and fully extract the printed circuit board from a back plane. When adjacent printed circuit boards are fully seated, the extraction handles align parallel the central plane and can support identifying labels in a clear and secure fashion.
