Abstract:
An expansion circuit board retainer for adjustably securing expansion circuit boards with various sizes to a main board of a computer system, comprising:a supporting bracket having a vertical rail and a horizontal platform extending in a first horizontal direction and for securing to the main board, wherein the vertical rail defines at least one threaded hole and the platform is fixed to the main board of the computer system; andan adjustable sleeve defining a tunnel for vertically slidably receiving and being mounted to the vertical rail of the supporting bracket, a slot in a wall of the sleeve and communicating with the tunnel for aligning with the threaded hole and providing at least one bolt extending therethrough to fix the sleeve at a position on the rail, said sleeve forming pairs of spaced blocks adapted to guide a side edge of a corresponding expansion circuit board and a retaining head to press the corresponding expansion circuit board downward for securing thereto; whereinthe retaining head extends in a second horizontal direction and defines a groove adapted to engage with a top edge of the corresponding expansion circuit board and press the corresponding expansion circuit board downward to a connector of the main board; whereineach of the pairs of spaced blocks defines a passageway for guiding and receiving the side edge of the corresponding expansion circuit board.
