Mechanical Method for Securing Stainless Steel Covers for a PCMCIA
Card Assembly

      This bulletin relates to a mechanical method for attach and
interlock stainless steel covers to a PCMCIA assembly.  It uses the
idea of "stitching" the two covers at regular intervals on the
perimeter
to lock them together for a uniform and non separable assembly.

      The stainless steel covers are U-shaped in cross-section and
consist of an inner and an outer cover.  Each of the covers is
provided with flanges or the like which are sufficiently long to
overlap upon assembly to form a box shape.  The overlap is
established at the flanges for almost full coverage.  Small holes are
added to the flange of the outer cover while larger holes are added
to the flange of the inner cover.  Alignment must be maintained
between them (Fig. 1).  An extrusion pin is forced into the small
hole of the outer cover forming and extruding the metal into the
larger hole of the inner cover (Fig. 2).  This results in a non
separable cover assembly.

      A variant of this method (Figs. 3 and 4) involves the provision
of tabs in the outer cover which are received into corresponding
slots provided in the inner cover.  As shown in Fig. 3(a), the inner
cover is first placed into the outer cover, whose inside wall angle
is approximately 105 degrees so as to facilitate placement of the
inner cover.  In Fig. 3(b), the outer cover wall is bent toward the
inner cover wall, thereby introducing th...
