Patent ID: 7209365

Claim:
A card retention device for latching an expansion card firmly in a chassis of a computer, to prevent the expansion card from becoming disengaged from an expansion slot of the computer, which comprises: a latch member including a stem which has a first latch section and a second latch section on two ends thereof, and an axle disposed between the first latch section and the second latch section, the first latch section being a stub extending from one side of the latch member; and a side wall located in the chassis of the computer including a pivot hole and a third latch section; wherein the axle of the latch member is engaged with the pivot hole to pivotally couple the latch member to the side wall, so that the latch member may be swiveled about an axis normal to the side wall relative to the side wall and to a position where the first latch section is latched on one end of the expansion card to urge the expansion card into the expansion slot, and the second latch section and the third latch section are coupled together to anchor the latch member which in turn latches the expansion card; and wherein when the latch member is swiveled away from the position, the second latch section and the third latch section uncouple from each other, and the first latch section is moved away from the one end of the expansion card to allow the expansion card to be removed from the expansion slot.
