Abstract:
1. A retaining device for securing an expansion card, the retaining device comprising: a chassis with a motherboard attached therein, the chassis comprising a side wall and a bent plate, the bent plate integrally extending from a top end of the side wall, a lower positioning section formed on the bent plate; a retaining member comprising a side plane, a support portion formed on the side plane; a riser card secured to the side plane of the retaining member, and interfacing with the motherboard, and a locking member pivotally attached to the wall of the chassis and pivotable with respect to the side wall about an axis which is stationary relative to the side wall, a pressing portion formed on an inner side of the locking member and a complementary positioning section defined in an outer side of the locking member, one of the lower positioning section and the complementary positioning section being deformable in a direction perpendicular to the bent plate; wherein the expansion card interfaces with the riser card and is mounted in the retaining member, the retaining member is then placed into the chassis, and the locking member is rotated downwardly with the pressing portion pressing against the support portion of the retaining member to retain the retaining member in the chassis, the lower positioning section engages with the complementary positioning section of the locking member to prevent the locking member from being rotated upward by accident.
