ABSTRACT:
An expansion structure for compact computers to install expansion circuit boards therein is provided. This expansion structure is small in dimension to save space in a compact computer and also allows easy installation of the expansion circuit boards. The expansion structure includes a base board on which an expansion circuit board is mounted, an enclosure having at least one engaging slot for accommodating the base board therein, and a main board which is mounted in the enclosure and formed with an electrical connector. The electrical connector is mounted in a connector receptacle provided on one edge of the engaging slot for the main board to have an electrical connection with the expansion circuit board. In installation the base board is inserted into the engaging slot allowing electrical connection pins on the expansion circuit board to come into contact with the electrical connector. After that securing means is used to secure the expansion circuit board in position in the engaging slot. Since the expansion circuit board is installed above and in parallel with the main board, the overall space taken by the expansion circuit board and the expansion structure is reduced. The expansion structure thus allows for increased expansion capacity for the compact computers.
