facing shoulders or surfaces 42b. Cover 16 also has forward and rearward transverse
flanges 44 and 46, respectively, which depend from the top wall of the cover that
defines smooth surface 16. The forward transverse flange 44 is engageable with stop
shoulders 48 (Figure 1) of connector housing 18 to define a fully mounted position of
the cover on the connector housing.
In operation, cover 14 is slidably mounted onto connector housing 18 in the
direction of arrow "A" (Figure 1) until the cover reaches a fully mounted position as
shown in Figures 2 and 5-7. Seto teaches (column 3, line 66, to column 4, line 16) that
[t]he cover is mounted on the connector housing with minimal or substantially
zero mounting forces as upwardly facing shoulders or surfaces 40b and 42b of
the cover easily slide beneath downwardly facing shoulders 28 and 26,
respectively, of the connector housing. However, when the cover is mounted on
the housing, the cover can be used to manipulate the connector as upwardly
facing shoulders 40b and 42b of the cover fully engage or abut against the
downwardly facing shoulders 28 and 26, respectively, of the connector. In
essence, these interengageable shoulders on the cover and the housing define
complementary interengageable releasable retention means that retain the cover
on the housing with substantial force in a direction generally normal to smooth
surface 16 of the cover, but that same means allows the cover to be mounted
onto and removed from the connector housing with minimal or substantially zero
forces laterally of that normal direction (i.e. generally parallel to the smooth
surface in the direction of arrow "A").
In our view Seto does not teach the "frictionally attaching" step of claim 1 (i.e.,
frictionally attaching, along the length of at least two sides of the package, without the
use of an adhesive, a removable and temporary clip to the microelectronic package).
