Abstract: An expansion board mounting structure that securely fastens expansion cards within the chassis of a computer is provided. A receptacle is positioned on an interior wall of the computer chassis. The receptacle contains vertical slots into which inserts, connected to expansion cards are inserted. The expansion cards are mechanically attached to the computer chassis at the receptacle found in the rear wall of the computer. Electrical connection is made in the board connecting portion found at the bottom of the computer chassis. The final assembly step requires that a cover be placed over the tops of the vertical slots. This requires the cover to be fastened to the receptacle containing the vertical slots. This attachment of the cover to the receptacle is accomplished without the use of screws or threaded fasteners.

Abstract: By placing the riser card comprising connectors for both ISA and IPC expansion cards in a connector arranged on the side of the motherboard of a computer of the AT type rather than in a connector arranged centrally of the motherboard, a large number of advantages are obtained: the routing of PCI signals is shortened; the cooling within the computer housing is improved; the components on the PCI expansion cards come to lie at the top of the card; the case for the computer can be simplified and there is no longer any connector arranged centrally of the motherboard which made the through-connection between components on opposite sides thereof rather difficult.

Abstract: The invention is directed to an electronic docking connector for edge mounting an electronic device, such as a daughter board, to a mother board. The connector comprises a pair of housing members assembled to define an elongated slot planarly aligned with the edge of the mother board.
