Locking Latch for Card Retention

      Disclosed is a locking latch for assisting in overcoming the
insertion and removal forces of circuit card connectors.  The latch
has a central locking beam that locks the latch in place after
insertion of a card.

      As shown in the Figure, latch 1 rotates about axle pin 4, while
pressing against an external ledge (not shown).  This provides
downward force to mate any connectors on circuit card 5.  At the end
of latch rotation, the locking beam 2 cams in the direction of the
arrow, and snaps back to lock a cylindrical boss into hole 3 in the
circuit card.  The locking beam prevents return motion of the main
latch body, effectively locking the circuit card in place.  The latch
is released with finger pressure in the direction of the arrow shown
on the locking beam.
