  • Patent number: 6791841
    Abstract: An electronic system has electronic equipment, and an electronic cabinet which houses the electronic equipment. The electronic cabinet includes a support structure which is configured to carry the electronic equipment, and a door panel which is configured to pivotally mount to the support structure. The door panel and the support structure define an opening through which a set of cables is configured to pass. The electronic cabinet further includes an assembly which is configured to manage the cables. The assembly includes a mounting bracket which is configured to mount to one of the support structure and the door panel at a location which is adjacent the opening, a section of flexible material which defines a set of grooves to hold the set of cables, and a fastener interconnected between the mounting bracket and the section of flexible material to fasten the section of flexible material to the mounting bracket.

  • Patent number: 6325472
    Abstract: A fastening device attaches a printed circuit board, such as a backplane, within a support framework of an electrical cabinet. The fastening device includes two adjacent members of the support framework. A threaded stud is attached to one of the members and extends toward the adjacent member. A captive fastener is attached to the other adjacent member. The captive fastener has a thread that cooperates with the thread of the stud. The fastener is aligned with the stud, the cooperative thread of the fastener is capable of engaging the thread of the stud. The fastening device secures the printed circuit board between the adjacent members of the support framework.

  • Patent number: 6324065
    Abstract: A stiffener supports a printed circuit board during insertion and removal within a slot of a card cage having one or more electrical connectors. The stiffener has a rigid elongated member that defines an elongated channel. The elongated member is adapted to engage an edge of the printed circuit board along the channel. The member has an engagement portion for receiving an applied force, a driver portion for engaging an electrical connecting mechanism, and a translator portion for translating the force from the engagement portion to the driver portion.

  • Patent number: 6323423
    Abstract: A housing receives a printed circuit board and a plurality of daughter boards. The housing has two opposing sidewalls, a floor, and a ceiling. The sidewalls extend from opposing sides of the floor to opposing sides of the ceiling. The opposing sidewalls, the floor and the ceiling defining an opening for receiving a daughter board within slots in the floor and the ceiling. A movable ceiling member attaches to the sidewalls. The ceiling, the movable ceiling member and the sidewalls define an opening for receiving a printed circuit board, such as a backplane, when the movable ceiling member is in an unsecured position. The movable ceiling member is aligned with the ceiling when the movable ceiling member is in a secured position. The movable ceiling member includes a fastener that secures the printed circuit board. The movable ceiling member accommodates printed circuit boards having various thicknesses.

  • Patent number: 6285563
    Abstract: A support bracket, which can be used in a method of reinforcing a printed circuit board, secures the printed circuit board, such as a backplane having a plurality of electrical connectors that engage corresponding electrical connectors of daughter boards. The support bracket includes a cross member attachable to the printed circuit board in a direction substantially transverse to a direction of motion of the daughter boards. The support bracket also includes first and second end support members attached transversely to the cross member at corresponding ends of the cross member. The end support members are fixable to a support surface and are adapted to secure the support bracket in the direction of motion of the daughter boards.

  • Patent number: 5828546
    Abstract: A customer removable storage system peripheral device cover is formed from two symmetrical right and left covers, each having a number of air channel openings spaced to meet finger insertion safety requirements. The covers are fastened together around grooved symmetrical guides hot staked on either side of a drive carrier. Inside the covers, a floating disk adaptor board is included at the rear to electrically connect the drive to the storage system. A ribbon wire cable is placed along the bottom of the interior of the device cover, to connect to an LED panel on the front of the device cover. An ejector pivotally attached to the device cover has locking tabs that grip a shelf of the chassis at the position where the drive is to be inserted, and propel the covered drive inward along rails in the chassis that fit into grooved symmetrical guides to snap the covered drive into its position and connect it to a backplane.

  • Patent number: 5665937
    Abstract: A strain relief bulkhead that provides EMI shielding for data cables being inserted into cabinets, including a conductive vise, slidably mounted on a stationary guide track that is permanently attached to a bracket made of conductive material to which a conductive cover panel is removably fastened. In a preferred embodiment the vise is moved along the guide track by a threaded screw which extends through threaded openings in the guide track. A C-ring holds the end of the screw to the vise. The bracket containing the vise and guide track is fastened to the cabinet which houses the printed circuit boards by screws or other means. The vise is located on the guide track and the guide track is attached to the bracket in such a way as to provide cable openings through which cables can be inserted.

  • Patent number: 5403214
    Abstract: A grounding jack for mechanically and electrically securely coupling a device to be grounded to a ground conducting member includes a generally circular shaped grounding jack having a first end adapted to be inserted into a grounding jack receiver hole in the ground conducting member. The grounding jack receiver hole includes a first predetermined diameter. A second end of the ground conducting jack is adapted for receiving a ground coupling plug from a device to be grounded. A central bore region, into which the ground coupling plug is inserted, extends from the second end to proximate the first end, and is substantially surrounded by a grounding jack wall region.
