Filed:

Jul 12, 2002

Appl. No.:

10/194799

Inventors:

Dennis R. Barringer - Wallkill NY
Gregory H. Richardson - Sumner WA
Harold M. Toffler - Newburgh NY

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H05K 506

US Classification:

361752

Abstract:

A hot docking mechanism enables a PCI type card with an edge connector to be inserted into an enclosure and docked in a card socket on the motherboard without operator access to the enclosure interior. A card holder carries the card and is supported on a card guide for sliding motion into the enclosure to a position at which the edge connector is aligned with the socket secured to the device motherboard. A camming assembly includes a cam lever extending outside the enclosure to convert horizontal or pivoting motion of the cam lever to vertical motion of the card into and out of the socket. The camming assembly, mounted above and proximate the mother board surface, increases mechanical advantage during docking and undocking. The card is supported within the card holder and the camming connection between the card and camming assembly is disposed intermediate the longitudinal ends of the socket to maximize mechanical advantage and minimize misalignment during card docking and undocking.

International Classification:

H05K 718

US Classification:

361801, 361759, 361726, 361754

Abstract:

A handle having a handle body, a latching arm, and a pivot block is provided. The handle body has a release finger and a pivot leg. The latching arm is slideably secured to the handle body. The pivot block is connectable to a device having at least one movable component. The pivot block is also connected to a first portion of the pivot leg so as to allow the handle body to rotate in the pivot block about the first portion between a first position and a second position. The first position is a locked position and the second position is a latched position.

Abstract:

A pluggable cartridge for inserting a circuit card into an enclosure without operator access to the enclosure interior is provided. The cartridge includes a top portion and a first wall configured to secure the circuit card thereon for movement in unison therewith and a second wall. The first and second walls have a bottom edge and a top edge wherein the top edge of the first wall is movably secured to the top portion. The top edge of the second wall is removably secured to the top portion by snap-fit means. The circuit card is housed within and protected by the first and second walls so as to be moveable with respect to the bottom edge of the second wall. A tail stock bezel is removably secured by snap-fit means at one end of the second wall and top portion. A handle is movably connected to the top portion so as to be movable between a first position and a second position. A portion of the handle is operably attached to the first wall by an articulated mechanical linkage such that movement of the handle to the first position causes the printed circuit card secured to the first wall to move to a position proximate the bottom edge.
