Riser card module and electronic device having the same

摘要

A riser card module includes a frame body, a carrier plate connected to the frame body for abutment against first surfaces of positioning plates of fixing brackets of expansion cards, a riser card disposed on the frame body and having a plurality of expansion slots for insertion therein of the expansion cards, respectively, and a limiting unit rotatable relative to the carrier plate about an axial direction which is perpendicular to a longitudinal direction of the carrier plate for abutment against second surfaces of the positioning plates of the fixing brackets of the expansion cards so as to restrict movement of the expansion cards relative to the riser card.

1. A riser card module for insertion of a plurality of expansion cards, each of the expansion cards including a circuit board and a fixing bracket, the fixing bracket including an elongated body disposed on the circuit board, and a positioning plate protruding from one end of the elongated body, the positioning plate having a first surface and a second surface opposite to the first surface, said riser card module comprising:
a support frame including a frame body, and a carrier plate connected to said frame body and adapted to abut against the first surfaces of the positioning plates of the fixing brackets of the expansion cards; a riser card disposed on said frame body and having a plurality of expansion slots for insertion therein of the expansion cards, respectively; and a limiting unit connected pivotably to said carrier plate, said limiting unit being rotatable relative to said carrier plate about an axial direction which is perpendicular to a longitudinal direction of said carrier plate, and being adapted to abut against the second surfaces of the positioning plates of the fixing brackets of the expansion cards so as to restrict movement of the expansion cards relative to said riser card.
