Abstract:
A printed circuit board card cage comprising:a first pair of opposing sidewalls, such sidewalls in the first pair thereof being disposed in first and second laterally spaced parallel planes, respectively, to provide a first space between the first pair of opposing sidewallsa second pair of opposing sidewalls, such sidewalls in the second pair thereof being disposed in the first and second laterally spaced parallel planes, respectively, to provide a second space between the second pair of opposing sidewalls;the first pair and second pairs of sidewalls being slideable relative to each other along a direction parallel to the first and second planes to provide a backplane printed circuit board receiving region between the first pair of opposing sidewalls and the second pair of opposing sidewalls when such first and second pair are slid apart into an open position to enable such receiving region to receive a backplane printed circuit board disposed transversely to the first and second planes and to have edges of the first pair of sidewalls engage portions of the backplane printed circuit board and have edges of the second pair of sidewalls engage opposite portions of the backplane printed circuit board when the first and second pair of sidewalls are slid towards each other to close the received backplane printed circuit within the printed circuit board receiving region;the first pair of sidewalls having slots therein to receive edge portions of a set of daughter boards and such first region being configured to receive therein the set of daughter boards and enable such set of daughter boards to be plugged into one side of the backplanea fastening device adapted to urge the second member to slide toward the first member to clamp the printed circuit board in the opening between the first and second sidewalls when the first and second sidewalls are in contact with the printed circuit board to provide the secured position by fixing the backplane within the backplane printed circuit board receiving region, such fastening device comprising:a stud attached to one of the sidewalls of the first pair of sidewalls and extending toward an opposing one of the sidewalls in the second pair of sidewalls, the stud having a threaded portion; anda captive fastener attached to the opposing one of the sidewalls of the second pair of sidewalls, the fastener having a cooperative thread; andwherein the fastener is aligned with the stud, the cooperative thread of the fastener being capable of engaging the threaded portion of the stud, the device being capable of clamping the backplane printed circuit board between the opposing first and second pair of sidewalls when the fastener engages the stud.
