Printed Circuit Card/Cassette Insertion Tool

       The device shown and described herein provides a means to
properly insert and seat printed circuit card/cassette assemblies.
This tool can be used on the production line as well as in the field
to eliminate card misplugging due to operator inconsistencies or
improper training.

      Referring to Fig. 1, printed circuit card cassette A is a unit
which utilizes a mechanical spring retention scheme that is used to
lock the cassette into an electronic package.  Printed circuit card/
cassette insertion tool B, is positioned onto the printed circuit
card cassette, and when actuated, reliably guides and seats a printed
circuit card into its mating connector system.

      Fig. 2 is an exploded perspective view of the tool.

      Printed circuit card/cassette insertion tool design features
are:
 1.   Polarization to printed circuit card cassette molded into the
front and back covers 1,4.  The tool can only insert a card when it
is properly orientated to the card's cassette.
      2.   Self alignment to the cassette's handle/retention springs
2. This is accomplished by molded in guides/bevels in the covers.
      3.   Insertion forces applied simultaneously and directly to
the top and bottom of the printed circuit card cassette.  This
provides parallel insertion forces to the top and bottom connectors
located in the electronic package.  This insures proper squareness of
card tabs to the conne...
