a cushion for absorbing the impact caused as an
edge of a circuit card hits a wall of an enclosure in a device which
As shown in
the drawing, a rigid plate 1 is adhered to a
cushion block 2, which may be composed, for example, of an
elastomeric foam. A double-sided adhesive layer (not shown), on the
side of cushion block 2 opposite plate 1, is used to attach the
cushion block to an enclosure wall 3 in a location adjacent to an end
4 of a circuit card 5.
This card 5
is mounted by means (not shown) to extend close
enough to wall 3 that contact between card end 4 and wall 3 may occur
when the device including wall 3 and circuit card 5 is dropped. In
this event, the shock absorbing capability of cushion block 2
prevents damage to enclosure wall 3 and to card 5, while plate 1
spreads the impact force from card end 4 across the end of cushion
block 2, which is therefore not cut by the edges of the card end.
