Printed Circuit Board Bracket for PS/2 Adapter Cards

      This bracket is designed to hold a PS/2* Micro Channel* adapter
card securely to a printed circuit board.  The bracket is attached to
the printed circuit board so that no external structure is needed to
keep the Micro Channel card in place.

      The bracket shown (Fig. 1) is used to hold PS/2 Micro Channel
adapter cards securely to a printed circuit board without any other
external structure.

      The bracket is mounted on the printed circuit board in line
with the Micro Channel card edge connectors.  The bracket has
alignment pins to position it on the printed circuit board.  It is
held in place with screws that go through the board.  The bracket has
a screw in the same place as the thumb screw in a standard PS/2 case
to hold the Micro Channel card.

      Normally, PS/2 adapter cards are held in place with a thumb
screw attached to the PS/2 case.  The Space Station DMS (Data
Management System) Kit uses a Micro Channel backplane, but in a
19-inch rack mounted case that is not designed to hold PS/2 adapter
cards.  It was found that the card edge connectors that make the
electrical connection to the PS/2 adapter cards were not sufficient
to hold the cards in place during normal use.  What was needed was a
way to hold the cards in place without connecting them to the case.

      A plastic bracket was designed that is mounted on the same
printed circuit board as the PS/2 card edge connec...
