Abstract: An apparatus is provided for coupling a printed circuit board within a printed circuit board cage. The apparatus includes a baseplate and a latch. The baseplate is mounted to the printed circuit board. The latch is rotatably coupled to the baseplate. The latch includes a pivoting portion, a shaft, and a swell nut. The pivoting portion includes an ejector extending from an end of the pivoting portion. The ejector is engageable with the printed circuit board cage. The shaft is coupled to the pivoting portion. The swell nut is coupled to the shaft and engageable with the printed circuit board cage.

Abstract: In a computer server orthogonally coupled processor and expansion circuit boards are respectively supported on corresponding vertical and horizontal chassis walls of the server. Upper and lower leveraged disconnect structures are respectively associated with the expansion and processor boards and are operative to disconnect either circuit board from the other circuit board without (1) disturbing the other circuit board, (2) using tools of any sort, or (3) damaging the mating circuit board connectors. The lower leveraged disconnect structure is also operative to recouple the disconnected processor circuit board to the undisturbed expansion circuit board.

Abstract: An apparatus is provided for coupling a printed circuit board within a printed circuit board cage. The apparatus includes a baseplate and a latch. The baseplate is mounted to the printed circuit board. The latch is rotably coupled to the baseplate. The latch includes a pivoting portion, a shaft, and a swell nut. The pivoting portion includes an ejector extending from an end of the pivoting portion. The ejector is engageable with the printed circuit board cage. The shaft is coupled to the pivoting portion. The swell nut is coupled to the shaft and engageable with the printed circuit board cage.

Abstract: A modular computer chassis configurable for both rack mounting and free standing use includes a housing with a multiple compartments for receiving computer devices and peripherals therein. The housing further includes side access panels and a top access panel, each being attachable and removable from the frame of the chassis without tools. The frame of the modular computer chassis is configured with slots to receive corresponding tabs on each of the side and top panels which facilitate the quick installation and removal of the side and top panels from the frame of the chassis. Multiple tool-less fasteners are used to further secure side and top covers to the frame of the chassis.

Abstract: An add-in circuit card is secured in an electronic device. A clamp is movably coupled to the electronic device and is configured to releasably engage the card upon movement of the clamp from a card engagement position to a card disengagement position. A switch may control electrical power to the card, the switch operated by the clamp such that movement of the clamp between the engagement and disengagement positions closes and opens the switch.

Abstract: A computer system electromagnetic interference (EMI) shield housing is bolted on a rack for allowing simplified access to modules and circuit boards mounted to a chassis which is slidably mounted to the interior of the housing. EMI gasketing is mounted integral with and extending around the perimeter of a first access opening of the housing and a rear access opening of the housing. A front panel and a rear panel of the chassis provides EMI shielding when the chassis is fully recessed within the housing. The chassis can be extended beyond the housing a distance adequate to allow access to all aspects of computer system modules and to cables at the rear of the chassis. A hinge mounted to the rear of the chassis and to the interior rear of the housing in conjunction with a cable trough and conduits located on the hinge allows power and input/output (I/O) cables to move outwardly and extend with the chassis.

Abstract: A expansion board including a main board, a common board and a system connector. The main board including a cutout and a board connector for receiving the common board. The common board having a data connector at one end and a board connector at the other end. The board connector being mounted perpendicular to the system connector to connectably mate to the common board whether components are mounted on either side of the main board. The main board includes circuitry for one of several expansion buses, the common board contains circuitry independent to any specific expansion bus.

Abstract: A tower unit housing for a computer system including a rectangular box-like chassis which receives a front bezel, a L-shaped hood to cover the top and one side of the chassis and a side member to cover the other side of the chassis. The chassis includes a security tab which is aligned with a hood security tab and a side cover security tab when the hood and side cover are installed on the chassis such that openings in the tabs can receive a single lock to lock the entire unit together. The front bezel includes its own security tab which extends into a pin connection inside of the chassis such that the pin connection between the bezel and the chassis is hidden by the side cover when the side cover and L-shaped hood are installed on the chassis. In this manner, a single lock can secure the front bezel and, the L-shaped hood and the side cover from unauthorized disassembly.

Abstract: An attachment unit interface electrical connector which includes a slide latch which is moveable between open and close positions utilizing a pivotally mounted tab member. The pivotally mounted tab member is mounted onto the slidably mounted latch so that the latch member is accessible even when the attachment unit interface female connector is attached to a male connector in an area of confinement.
