Abstract

All computers that use Peripheral Component Interconnect (PCI) and/or ISA adapter cards attach the card to the rear of the computer with a screw through a bracket which is part of the card assembly - the back bracket. However, there is currently no provision for attaching the forward end of the card in any way and the card is free to slide around within the forward card guide. Lack of a secure mechanical attachment at the front end can allow cards to shift during shipping and partially unplug from the connector on the planar or mother board. This disclosure describes two methods of securing the forward end of the adapter cards. The first (Figs. 1 and 2) uses a "C" shaped metal or plastic bracket to close the upper end of the card guide slot after the card has been installed and secure the card while the second (Figs.

Securing Adapter Card within Card Guide Groove

      All computers that use Peripheral Component Interconnect (PCI)
and/or ISA adapter cards attach the card to the rear of the computer
with a screw through a bracket which is part of the card assembly -
the back bracket.  However, there is currently no provision for
attaching the  forward end of the card in any way and the card is
free to slide around  within the forward card guide.  Lack of a
secure mechanical attachment  at the front end can allow cards to
shift during shipping and partially  unplug from the connector on the
planar or mother board.  This disclosure  describes two methods of
securing the forward end of the adapter cards.  The first (Figs. 1
and 2) uses a "C" shaped metal or plastic bracket to close the upper
end of the card guide slot after the card has been installed and
secure the card while the second (Figs. 3 and 4)  requires a unique
card guide containing an internal thread that accommodates a screw
for card retention.

      Fig. 1 shows one method of securing the forward end of the card
in the card guide groove.  This solution requires that the outer end
of the card guide be designed to accept the addition of a "C" shaped
metal or plastic bracket that is tapped to accommodate a machine
screw. After  the card has been installed, the bracket is slid over
the end of the card  guide and the screw is tightened against the top
edge of either the plastic card extender or the edge of the...
