Abstract: An enclosure is provided for containing the logic elements and ancillary components for computing systems. The enclosure is a unitized central electronics enclosure (CEC) wherein the primary structural element is the enclosure for the logic elements. This enclosure or logic cage includes unitary side plates, a double-sided backplane and top and bottom cast guides. The integrated structural and enclosure functions accommodate the structural needs of a CEC, as well as containing and supporting the logic elements and ancillary equipment.

Abstract: A data processing system is shown packaged in an enclosure wherein the system frame or chassis and a cable carrier are separately fabricated and thereafter merged to provide an enclosure with open ends and a central cable carrier that mounts connections for the system components. The system components are slideably received by the enclosure and are self docking as the electrical connections with the system power and signal lines are completed as the components arrive at the fully inserted, latched position. Keying means are also provided to require the user to install the components at both the correct location and with the correct orientation.

Abstract: Interconnection between a large planar electronic printed circuit board and a plurality of relatively smaller electronic printed circuit cards is accomplished by connecting the planar board to an array board by means of elongated interposer connectors. The array board contains a plurality of positions which accommodate the plugging of electronic printed circuit cards and cables. A mechanical ejection system allows the planar board to be removed from the system without disturbing the cards, cables or the interposer connection to the array board.
