Appl. No.:

10/422259

Inventors:

Surrinder S. Puri - Schaumburg IL
Dennis Strong - Sugar Grove IL
Marc E. Krause - Darien IL

Assignee:

Tellabs Operations, Inc. - Naperville IL

International Classification:

H01R 1362

US Classification:

439157, 439 95

Abstract:

An electrical system comprises an electrical circuit board for mounting electrical components and a circuit board sub-rack. The board includes a pivotally mounted ejector member which pivots to insert and eject the board from the sub-rack. The ejector member carries two grounding contact surfaces for engagement with the ground plane of the board and chassis area of the sub-rack when the ejector member is pivoted to its closed position. The contact surface of the ejector member mates with the board to frictionally hold the board in fully inserted position. The ejector member also includes a retaining arm which mates with the sub-rack for providing an insertion or ejection force to facilitate insertion or ejection of the board relative to the sub-rack.
