Patent number: 5946189Abstract: A combination support and heat sink structure is mounted within a computer housing for pivotal movement between connected and disconnected positions and includes a pair of cooling plates, one air cooled and the other liquid cooled, carried in a spaced apart, parallel opposing relationship. The two cooling plates are movable toward and away from one another and a pair of manually operable spring clip members permit a processor card to be removably sandwiched and clamped between the cooling plates without the use of tools.Type: GrantFiled: October 5, 1998Date of Patent: August 31, 1999Assignee: Compaq Computer CorporationInventors: David J. Koenen, Kenneth A. Jansen

Patent number: 5896268Abstract: A repeater case for high-density subscriber lines includes a repeater base and repeater case housing formed of a fiberglass composite and together forming a sealed enclosure for a pressurized atmosphere. The repeater case housing has a removable cover secured in position by torque bolts, a sealing gasket to sealingly receive the cover, a plurality of high-density subscriber line module slots and a plurality of printed circuit boards mounted to certain of the slots with gaps between adjacent printed circuit boards, the printed circuit boards being adapted to receive respective high-density subscriber line modules. The repeater base has a cable inlet, and each of the plurality of printed circuit boards is provided with a connection to the cable inlet and a connector to electrically receive one of the high-density subscriber line modules. The repeater base also includes an electrically insulating barrier between the cable inlet and the printed circuit boards.Type: GrantFiled: August 11, 1997Date of Patent: April 20, 1999Assignee: Abacon Telecommunications CorporationInventor: Roger L. Beavers

Patent number: 5892658Abstract: A dual-board host or main printed wiring structure of a circuit module with increased component mounting area is made plug-compatible with a backplane to which single-board host or main boards may be attached with connectors of differing dimensions and pin configurations, the center line of which are offset from each other. The connection sides of the two boards are respectively bonded to a heat sink frame structure having a thickness which corresponds to the connector offset on the backplane such that the total thickness of one of the printed wiring boards, the heat sink frame and the two bonding layers with respect to board to center line distances equals the connector offset on a given backplane. Direct connections to both boards of the dual-board structure can thus be made from the backplane to reduce connection length and reliability relating to a mezzanine board mounted on a single-board host.Type: GrantFiled: May 12, 1998Date of Patent: April 6, 1999Assignee: Lockhead Martin CorporationInventors: Eugene J. Urda, Magid Fazel, Jose R. Caceres, Daniel G. Rice

Patent number: 5808236Abstract: An apparatus and method therefore mount an array of different heatsinks to a closely packed array of data processing elements utilized within a data processing system. The apparatus includes a metal frame with multiple apertures in the bottom to allow access to the tops of the devices for which heatsinks will be provided. The metal frame has multiple apertures that allow access to the tops of the data processing elements underneath. The metal frame serves as a containment vehicle for multiple heatsinks, and also provides rigidity to the printed circuit board in the particularly vulnerable vicinity of the corners where the devices are attached to the printed circuit board.Type: GrantFiled: April 10, 1997Date of Patent: September 15, 1998Assignee: International Business Machines CorporationInventors: Johnny Roy Brezina, John Saunders Corbin, Jr., Howard Victor Mahaney, Jr., James Robert Taylor
