Mounting apparatus for expansion cards

A mounting apparatus for securing expansion cards with cover plates to a computer, the mounting comprising:

• a chassis comprising a rear panel, the rear panel comprising a mounting frame and a pair of guiding portions above the mounting frame, each of the guiding portions defining a locating aperture therein;
• and
• a mounting member slidably received in the guiding portions of the rear panel, the mounting member comprising a main portion and a pair of operating members, the main portion comprising a base, and first and second sidewalls extending upwardly from two opposite sides of the base, the operating members pivotally secured between the first and second sidewalls, each of the operating members having a fastening portion, an engaging means disposed at the mounting member for retaining the operating members;
• wherein when the cover plates are attached to the mounting frame of the rear panel of the chassis, the mounting member is driven downwardly toward the cover plates until the base of the mounting member presses the cover plates, and the operating members are rotated until the fastening portions engage in corresponding locating apertures of the guiding portions, and wherein when the operating members are secured by the engaging means, the expansion cards are thereby mounted to the chassis.

A mounting apparatus assembly comprising:

• a plurality of expansion cards with cover plates thereof;
• a chassis comprising a rear panel with a bent portion thereon;
• a bracket mounted on the rear panel above said bent portion;
• and
• a mounting member slidably, in a vertical direction, received in the bracket, the mounting member comprising a main portion and at least one operating member, the main portion comprising a base to which said one operating member is pivotally mounted;
• wherein
• when the cover plates are attached to the rear panel, the mounting member is driven downwardly toward the cover plates until the base of the mounting member contacts the cover plates, and the operating member is rotated until one end of the operating member abuts against one portion of the bracket to result in further downward movement of the mounting member by a reaction force derived from confrontation between the mounting member and the bracket, and such rotation terminates when said operating member reaches a final locking position where said reaction force is maximum, wherein the cover plates are sandwiched between the bent portion and the mounting member in the vertical direction.
