A system rack configured to house rack-mount modules comprising a support structure; a rack-mount module slidingly mounted within the support structure; a carrier rail system slidingly supporting the module and comprising a pair of linear slides each secured to the support structure on opposing sides of the module, each linear slide comprising a stationary slide rail fixed to the support structure and one movable slide rail linear translatable relative to the stationary slide rail and fixed to the module; and a user-controllable latching mechanism operatively coupled to the module to releasably restrain the module in at least one position relative to the support structure.

User-controllable latching carrier rail system

A latch is designed to attain and keep full engagement of a sub-assembly in a chassis and to increase the reliability and longevity of connectors by increasing the chances that they remain fully engaged even in the presence of shock and vibration.

An apparatus for adjoining along a mating axis a first and second circuit board to directly mate a first integrated connector of the first board with a second integrated connector of the second board is disclosed. The apparatus comprises an attachment plate to be supported in a substantially horizontal plane; a plurality of extension arms extending downward from the plate to suspendingly restrain the first board away from the plate; at least one stop configured to be secured to the distal end of one of the plurality of extension arms to support the first board in suspension away from the plate; and a plurality of attachment elements to secure the plate to the second circuit board without applying substantial forces to the first circuit board.

Attachment plate for directly mating circuit boards

A computing system includes a circuit board, a first connector portion electrically connected to the circuit board, an electronic component and a plurality of resilient support members. The electronic component includes a first electronic device, a second connector portion electrically coupled to the electronic device and connected to the first connector portion along an axis. The plurality of resilient support members are asymmetrically located about the axis and extend between the device and the circuit board.

An apparatus for adjoining along a mating axis a first and second circuit board to directly mate a first integrated connector of the first board with a second integrated connector of the second board is disclosed. The apparatus comprises an attachment plate to be supported in a substantially horizontal plane; a plurality of extension arms extending downward from the plate to suspendingly restrain the first board away from the plate except to permit the first board to translate along the mating axis toward the plate; an pressure platform extending downward from the plate to apply to the first board a mating-axis force collocated with the first connector; and a plurality of attachment elements to secure the plate to the second circuit board without applying forces to the first circuit board. Forces applied to the plate are transferred to the first board through only the pressure platform.

A circuit board assembly and a method for protecting and covering an interface opening of a connector. The circuit board assembly includes a bulkhead member having a bulkhead aperture, a circuit board having a connector with an interface opening and passing through the bulkhead aperture, and a cover member disposed over the interface opening. A coupling member is provided for coupling the cover member to the connector. The method comprises passing the connector including the interface opening through the bulkhead aperture, and releasably covering the interface opening with a cover member that is coupled to the connector.

A cable connector riser is provided configured to be positioned between a circuit board side of a receiving connector and a circuit board. The cable connector riser has a base portion having a thickness sufficient to provide clearance for a housing of a mating connector on a cable, the housing including a portion projecting downward towards the circuit board from a bottom surface of the mating connector.

The present invention is electromagnetic interference containment apparatus. In one embodiment, a layer of compressible material is disposed between an electromagnetic interference source and a bulkhead coupled to the electromagnetic interference source. The layer of compressible material has a first thickness and a second thickness. A first layer of conductive material is disposed on the back side of the layer of compressible material and is electrically coupled to the electromagnetic interference source. The first layer of conductive material is for absorbing electromagnetic emissions from the electromagnetic interference source. A second layer of conductive material is disposed on the front side of the layer of compressible material and is electrically coupled to the first layer of conductive material. The second layer of conductive material is for electrically contacting the bulkhead and for conducting the electromagnetic emissions to the bulkhead.

A computer system housing for providing an attenuating barrier for electromagnetic interference (EMI) noise. The computer system housing includes a backplane wall having a plurality of connectors for receiving PCB's, and a bulkhead wall coupled to the backplane wall. The bulkhead wall defines a plurality of bulkhead slots through which connector receptacles of printed circuit boards (PCB's) can extend. An EMI bulkhead gasket is positioned on the bulkhead wall. A conductive metal impregnated, elastomer EMI gasket is positioned on a mounting flange of the bulkhead wall. The computer system housing also includes a plurality of bulkhead plates. The bulkhead plates contact the EMI bulkhead gasket and the elastomer EMI gasket along their entire peripheral edges so that EMI noise is conducted through these gaskets to the bulkhead wall. The computer system housing further includes a bulkhead plate alignment and mounting system that does not employ separable fasteners. This allows &ldquo;hot plugging&rdquo; of PCB's to the computer system housing.

The card removal method and system easily removes a PCA card from a powered on computer system while minimizing damage to the computer system and to the individual removing the PCA. The printed circuit assembly card removal system is comprised of: an ejection card including at least a first ejector extending from the surface of the ejection card, the ejector having a first surface for pressing against the edge of the PCA card to be removed, and an ejection card holder for mechanically supporting the ejection card. To remove the PCA, the ejection card is pulled outward causing the ejector to apply a force to the edge of the PCA card to be removed, forcing the card edge fingers of the PCA card out of the PCA connector.

A printed circuit board (PCB) assembly includes a PCB having and a ferrite attenuator. The PCB includes input/output signal paths for carrying signals to and from the PCB, power paths for conducting power to the PCB, and ground paths for connecting the PCB to a ground level. The ferrite attenuator surrounds the input/output signal paths, the power paths, and the ground paths. The PCB assembly is preferably used in a system, such as a computer system, where the ferrite attenuator suppresses electromagnetic interference (EMI) generated in the system.
