Easily Reconfigurable Connection

       There is a steady demand from customers to be able to
reconfigure or implement a different mix of interconnects on IBM
products, including personal computers and point of sale (POS)
products.

      This may be difficult on all existing point of sale and PC
equipment.  The connection panel on existing POS products is designed
as part of some larger sub-assembly such as the planar board or power
supply.  Since this prevailing design method fixes the connection
panel to some expensive sub-assembly, there is some reluctance to
modify or upgrade the connection panel.  This article solves the
problem by making an easily replaceable assembly of the connection
panel such that no other part of the machine is affected by the
upgrade.

      Referring to Figs. 1 and 2, the connection panel includes
unique I/O connectors mounted to a printed circuit card, a metal
grounding plate with EMC fingerstock, and a self-aligning power
connector.  The self-aligning power connector is mounted to compliant
spacers and is electrically connected to the printed circuit card
with flexible cable.

      The connectional panel is assembled into the logic unit by
pressing it into the opening in the logic unit chassis.  At the same
time the self-aligning connector is mating with the power and signals
interposer, the EMC fingerstock on the metal panel contacts the
perimeter of the opening in the metal chassis.  Not only does the
connection pan...
