The disclosed invention relates to a computer system, including a crib device and chassis and including a U-shaped actuator and handle with distinct cam surfaces for installing and removing a hard drive to and from the chassis of the system. The drive is securable to the crib device, which has a handle that allows the drive to be carried to and away from the chassis. The crib device and chassis have cams and cam engaging surfaces that cause the crib device and drive to move to effect engagement and disengagement of the electrical connectors of the computer system and drive.

An improved attachment mechanism for attaching the motherboard in a computer system to its chassis is disclosed. The attachment mechanism includes a rail that engages at least two opposing edges of the motherboard and a hook mechanism that engages a catch formed in the chassis. The hook mechanism is secured to a central portion of the motherboard. The rail and hook mechanism cooperate to securely couple the motherboard to the chassis without requiting the use of extensive usable space on the motherboard. The described arrangement permits the motherboard to be quickly and easily installed and released.

A test fixture which holds multiple circuit boards in an edge-to-edge configuration for testing includes a sliding interconnect mechanism which is located between the circuit boards under test. The interconnect mechanism includes an interconnect board on which are mounted pairs of inter-wired frame connectors which mate with the connectors on each of the printed circuit boards to be tested and electrically interconnect the boards. The interconnect mechanism includes guide pins on which the interconnect mechanism slides to accurately align the frame and board connectors and an actuating mechanism to move the interconnect mechanism into position to securely mate the aligned connectors. The actuating mechanism can also be reversed to unmate the connectors and release the boards under test after the tests are completed.

An apparatus for securing a conductor to a circuit board. The conductor is configured for being soldered to the circuit board through a first aperture in the board. The apparatus includes a conductor supporting portion having a second aperture therethrough. The conductor supporting portion is configured for coupling to the circuit board. The second aperture substantially aligns with the first aperture when the conductor supporting portion is coupled to the circuit board to permit the conductor to be inserted through both the first aperture and the second aperture. The apparatus includes a tab portion configured for coupling to the conductor supporting portion. A portion of the conductor is thus held substantially immobile between the conductor supporting portion and a first edge of the tab portion when the tab portion is coupled with the conductor supporting portion, thereby preventing the conductor from being broken at the portion of the conductor when the conductor is flexed.

An insulating guard is mounted over a backplane or motherboard in an electronic system that accepts hot pluggable circuit cards. The insulating guard has openings that expose only the connectors and allow a hot pluggable circuit card to be inserted without the possibility of shorting the backplane. In order to prevent contact between a card being inserted and adjacent cards that have already been connected to the system, the invention provides for insulating card dividers which are connected to the insulating guard and fit between adjacent cards. The card dividers can be attached to the insulating guard by parts which snap together, fasteners or adhesives.

A method and apparatus relating to a support bracket (18) enabling hot-swapping of component trays (16) in component racks (10) is disclosed. A bracket (18) is provided for removably mounting a tray (16) in a component rack (10). The bracket (18) has two guide channels (20) extending substantially from a front end of the bracket (18) through to a back end. The guide channel (20) is adapted for sliding engagement with the component carrying tray (16). In addition, there is at least one stop guide (30) that projects from each of the front and back ends of the bracket (18). This stop guide (30) aids in positioning the bracket (18) during installation. On a backside of the bracket (18), there is a detent (32) that projects outward. The detent (32) serves as an aid in positioning and releasably holding the bracket (18) in place during installation. The configuration of the bracket (18) allows it to be used as either a bottom bracket (18) or a top bracket (18) for mounting a tray (16), without any additional modifications.

A card retention mechanism securely holds a card within a slot on a circuit board. The retention mechanism may include a carrier and a retainer. The carrier mounts to a chassis of the computer system adjacent to the card slot. The retainer may be pivotally mounted to the carrier. When the retainer is in a closed position, at least one surface of the retainer engages an endplate of the card, and the retainer engages the carrier. The engagement of the retainer and the carrier inhibits rotation of the retainer from the closed position to an open position. When the retainer is in the closed position, the retainer securely holds the card to the chassis of the computer system.
摘要:
For a circuit board populated with numerous components having different heights, the need for numerous individual heatsinks to accommodate the circuit board's multilevel surface is eliminated. Instead, heat is transferred to a single integral heatsink via a thermal-conductive material (i.e., a thermal phase change material and/or a resilient gap filling material). A fastener secures the thermal-conductive material between the bottom portion of the heatsink and the multilevel surface, and compresses the thermal-conductive material therein, creating a thermal path sufficient to transfer heat from the multilevel surface to the heatsink so that the circuit board operates within specified design parameters.
