Patent ID: 8382215

Claim:
A computer enclosure comprising: a computer panel with a slot defined therein and a support piece extending from the computer panel, the support piece is located above the slot; and the computer panel comprising a top flange extending perpendicularly therefrom, and a groove defined in the top flange; an expansion card shield comprising a main piece covering the slot and a resisting tab abutting the support piece; and a retaining member, pivotably attached to the computer panel, comprising a main portion and a clasping portion connecting to the main portion; the main portion comprises a bottom plate and a side plate perpendicularly extending from the bottom plate, the retaining member is pivotably attached to the computer panel via the bottom plate; the clasping portion comprises an extending piece and an operation piece extending perpendicularly from the extending piece, the extending piece is in the same plane with the side plate of the main portion, the operation piece is perpendicular to the side plate and parallel with the bottom plate, at least one bulge located on and protruding downwardly from the operation piece; wherein the retaining member is capable of rotating between a closed position, where the bottom plate abuts on the supporting piece, the side plate abuts on the computer panel, the operation piece is biased and abuts on the top flange of the computer panel, the at least one bulge located in the groove therein, thereby securing the expansion card shield, and an open position where the at least one bulge is disengaged from the groove, thereby disengaging the expansion card shield; wherein the computer panel comprises a flange extending from the support piece and a tab protruding from one end of the flange, a first pivot hole and a second pivot hole are defined in the retaining member, and the tab is pivotably engaged in the first pivot hole, a mounting piece extended downwards from a side edge of the support piece, a circular hole is defined in the mounting piece and aligned with the second pivot hole, and a fastener is engaged into the second pivot hole and the circular hole, thereby pivotably attaching the retaining member to the computer panel.
