Abstract

All computers that use Peripheral Component Interconnect (PCI) and/or Industry Standard Architecture (ISA) adapter cards attach the card to the rear of the computer with a screw through a bracket which is part of the card assembly - the back bracket. However, there is currently no provision for restricting the outward motion of the forward end of the card in any way. Shock experienced during shipping of the computer may unseat the card from its connector on the planar or mother board if outward motion of the forward end of the card is not prevented. This publication describes a method of preventing this outward motion of the card's forward end. A plastic pinching device interacts with a strip of grooves or serrations on the side of the forward card guide to prevent any outward card movement.

Adapter Card Retention Device

      All computers that use Peripheral Component Interconnect (PCI)
and/or Industry Standard Architecture (ISA) adapter cards attach the
card to the rear of the computer with a screw through a bracket which
is part of the card assembly - the back bracket.  However, there is
currently no provision for restricting the outward motion of the
forward end of the card in any way.  Shock experienced during
shipping of the computer may unseat the card from its connector on
the planar or mother board if outward motion of the forward end of
the card is not prevented.  This publication describes a method of
preventing this outward motion of the card's forward end.  A plastic
pinching device interacts with a strip of grooves or serrations on
the side of the forward card guide to prevent any outward card
movement.

      This invention provides a mechanical method of limiting the
outward movement of the forward end of the card in the card guide
groove.  A plastic pinching device interacts with a strip of grooves
or serrations on the top of the card guide to block outward movement
of the card.  This pinching device is placed over the outer end of
the card guide after the card has been fully inserted into the
adapter card  slot.  Any outward motion of the card is blocked by the
locking action  between the groove pattern on the card guide and the
locking pawl on the  pinching device.  The card guide grooves can be
either molded into the  pa...
