US Patent 7209365 Card retention device

A card retention device includes a latch member pivotally coupled on a side wall which is located in a chassis of a computer and is located corresponding to a distal end of an expansion card. The latch member includes a stem which has a first latch section and a second latch section on two ends. The first latch section is a stub to latch the upper edge of the distal end of the expansion card. The second latch section may be coupled with a third latch section formed on the side wall to enable the latch member to latch the expansion card and prevent the expansion card from becoming disengaging from the expansion slot where it is engaged.
