Patent number: 7269895Abstract: Method and systems for clamping at least one circuit card within a case are provided. The method includes compressing axially at least one resilient element between a head of a shaft and a nut disposed on the shaft so that the at least one resilient element bulges generally perpendicularly to the axial direction and into engagement with the at least one circuit card, exerting a force on the at least one circuit card using the at least one resilient element and maintaining the force on the at least one circuit card using the at least one resilient element.Type: GrantFiled: April 5, 2005Date of Patent: September 18, 2007Assignee: ADC Telecommunications, Inc.Inventors: Gary Gustine, Charles Ham, Matthew J. Kusz, Michael Sawyer

Patent number: 6992249Abstract: A method for confining circuit cards to different locations within a housing is provided. The housing includes a frame having an array of slots, each containing one of the circuit cards. In one embodiment, the receptacle has a cam that is selectively engageable with the frame for clamping the circuit cards within the frame. In another embodiment, a shaft is rotatably attached to the receptacle. The shaft has a head at one end and a nut opposite the head. A resilient element is disposed on the shaft between the head and the nut. The resilient element is axially compressible between the head and nut to bulge generally perpendicularly to the axial direction into engagement with the frame for clamping the circuit cards within the frame.Type: GrantFiled: April 5, 2005Date of Patent: January 31, 2006Assignee: ADC Telecommunications, Inc.Inventors: Gary Gustine, Charles Ham, Matthew Kusz, Michael Sawyer
