CPU card mounting structure

A CPU card mounting structure comprising an electrical connector installed in a mother board and comprising a card slot, a substantially U-shaped mounting frame mounted on said electrical connector, a CPU card mounted in said U-shaped mounting frame and inserted into the card slot of said electrical connector to be electrically connected to said mother board, and two holding down devices respectively fastened to said U-shaped mounting frame at two opposite sides to hold down said CPU card, wherein:

• said U-shaped mounting frame comprises a horizontal section, and two vertical sections respectively upwardly raised from two opposite ends of said horizontal section at right angles, said horizontal section comprising a connector slot adapted for receiving said electrical connector, and coupling means adapted for coupling to respective coupling means of said electrical connector, each of said vertical sections comprising a longitudinal sliding groove at an inner side, the longitudinal sliding grooves of said vertical sections being respectively connected to two opposite ends of the card slot of said electrical connector at right angles;
• said electrical connector comprises coupling means disposed inside the card slot thereof, and adapted for coupling to the coupling means of said U-shaped mounting frame;
• said CPU card is inserted through the longitudinal sliding grooves of the vertical sections of said U-shaped mounting frame into the card slot of said electrical connector, and held down in the card slot of said electrical connector in a vertical position by said holding down devices;
• said holding down devices are respectively fastened to the vertical sections of said U-shaped mounting frame to hold down said CPU card in said electrical connector.
