Abstract: A high connector density printed circuit board, and high connector density device containing the same, including one or more of the following: a face plate; a plurality of connector ports in the face plate; a tab integral with the face plate label and bent to extend away from the face plate; information printed on the tab; the tab forming a plane at an angle of ninety degrees with respect to the face plate; the tab fabricated from a material having a combination of a thickness and a stiffness minimally able to resist a deformation resulting from a force of gravity; a second tab that is integral with the face plate and bent to extend away from the face plate; and the tabs do not infringe on an adjacent space occupied by another high connector density printed circuit board.

Abstract: A ventilated housing for accommodating one or more components comprises opposed first and second-spaced apart end portions. An air barrier extends at least partially between the first and second end portions for limiting movement of air inside the housing and defining an upper or lower surface of the housing. A first part of the air barrier proximate the first end portion is positioned at a level below the level of a second part of the air barrier proximate the second end portion. An inlet is defined for admitting air into the housing and an outlet is defined for discharging air from the housing. An ventilated housing assembly comprises first and second housings with an angled space between a lower air barrier of the first housing and an upper air barrier of the second housing.

Abstract: An electronic circuit pack having a printed circuit board with a faceplate at a front of the board. The faceplate has two end regions carrying latches for holding the board into a shelf. A front wall of the faceplate has an intermediate part between the end regions, the intermediate part extending forwardly of the end regions and lying at least between the latches. Preferably, the intermediate part of the front wall extends as far as a frontal vertical plane of the shelf which is the foremost position allowable for a shelf and a circuit board combination. The intermediate part of the front wall lying in this forward position provides additional space behind it for extending the electronic circuitry of the circuit pack for a unitary shelf size. This additional space is occupied by the printed circuit board with conductors and electronic components and/or connectors for test purposes and memory cards.
