Snap and Turn Retainer for Book Package Cover and Card Control

      Described is a method of retaining a printed circuit (PC) card
in an enclosure by means of a simple two-piece snap-in plastic part.
The snap-in parts control the location of the card between the covers
as well as preventing the covers from expanding or collapsing inward.

      One of the snap-in plastic parts consists of a segment 3 which
is inserted into a keyed square opening in the cover 2.  When fully
inserted, this segment 3 locks into the cover 2 by a snap action
feature.  The end of this segment 3 rests against the circuit card 1.
The square shape of this segment 3 and its receptacle prevents any
rotational movement of the segment 3 (see Fig. 1).

      The other snap-in plastic part 4 consists of a circular section
with a head diameter larger than the body diameter.  A tab protrudes
from the circular body portion of the part.  A dart-like feature is
positioned with its compression normal to the protruding tab (see
Fig. 1).

      The cover 5 has a feature 6 which is circular with a diameter
which will accept the body diameter of the part 4.  It also has a key
slot which is oriented at thirty degrees in relation to the square
hole in the opposite cover 2.  The key slot will accept the tab on
the part 4 (see Fig. 1).

      The circuit card has a hole which is coaxial to the holes in
the covers 2 and 3.  This part 4 is inserted dart first into the
feature 6 in the cover 5....
