  • Patent number: 7360659
    Abstract: Components can be received within regions of limited access present in an equipment-supporting rack using an installation fixture including a pair of mounting plates which are pivotally connected to each other by a hinge positioned along lateral edges of the respective mounting plates. One mounting plate includes a bracket for fixed connection to the rack, and the other mounting plate includes a surface for receiving a desired component. Rotation of the mounting plate receiving the component relative to the mounting plate fixed to the rack permits the component to be conveniently accessed when servicing is desired, and returned to the region of limited access during normal system operations. A locking mechanism is preferably provided for securing the component and the mounting plate which receives the component in desired position during normal system operations.
    Type: Grant

  • Patent number: 7296523
    Abstract: Components can be received within regions of limited access present in an equipment-supporting rack using an installation table including a pair of mounting plates which are pivotally connected to each other at a corner of the respective mounting plates. One mounting plate includes a bracket for fixed connection to the rack, and the other mounting plate includes a surface for receiving a desired component. Rotation of the mounting plate receiving the component relative to the mounting plate fixed to the rack permits the component to be conveniently accessed when servicing is desired, and returned to the region of limited access during normal system operations. A channel is preferably provided to guide and limit movement of the mounting plate which receives the component, and a locking mechanism is preferably provided for securing the mounting plate and the component it receives in desired position during normal system operations.

  • Patent number: 6942512
    Abstract: An electrical connector is provided which can releasably engage a circuit card within a slot defined by the electrical connector. A camming mechanism is provided which includes a cover having a series of follower surfaces for cooperating with a corresponding series of camming surfaces and recesses associated with a pin holder. Longitudinal movement of the cover causes the cooperating surfaces to spread open card edge receiving portions of the slot, or to close down over the portions of the circuit card to be engaged. The electrical connector preferably has an opening in one end to allow a circuit card to enter the slot from the side, allowing circuit cards to be removed from or installed in a rack, frame or other chassis from the side.
