Abstract

One requirement of the Argos card-on-board package is the use of a DC-DC daughter card (1) mounted directly to the Argos board (2). The appropriate connector system (3) used to mate this daughter card with the board offers no additional card retention other than its mating force.

Circuit Card Retainer

      One requirement of the Argos card-on-board package is the use
of a DC-DC daughter card (1) mounted directly to the Argos board (2).
The appropriate connector system (3) used to mate this daughter card
with the board offers no additional card retention other than its
mating force.

      An additional external device is required to insure this card
retention.  The part that was designed to meet this function is
illustrated in the Figure.

      The construction of the retainer (4) is such that it contains
two holes.  The upper hole (A) is meant to be the pivot to allow
rotating the retainer out of the way in order to install or remove
the card.  The 2nd hole (B) houses an off the shelf spring loaded
plunger (5) which acts as a locator for the retainer.

      The V-shaped groove (C) which straddles the card is located
such that it restricts motion of the card in two axes during
operational vibration and its location prevents any of the card's
components to come into contact with the metallic cage (6) sidewall.

      The pivoting feature gives added flexibility to the method of
shipment and further assembly while resident in the DSD processor.
The circuit card is shipped separately from the board/cage/retainer
assembly.  Therefore, the retainer is mounted in its non-functional
position until the card is installed.  The spring loaded plunger is
pulled to retract it from a mating hole in the cage sidewall.  The
retainer is...
