I/O card and connection mechanism thereof

摘要

An I/O card (10) includes an internal PC board (26) attached to the frame means (12, 18) which extend along the edges of the PC board (26). A top panel (60) and a bottom panel (40) sandwich the frame (12, 18) and its associated PC board (26) therebetween. A socket connector (34) is positioned at the rear end of the I/O card (10). Oppositely, a specifically shaped and dimensioned opening (21) extends through the front wall (14) of the frame (12) in a front-to-end direction whereby a projecting section (29) of the PC board (26) extends into the opening (21). Two rows of traces (31) are staggeringly positioned respectively on opposite surfaces of the PC board (26) along the projecting section (29) so that when a card edge cable connector (70) is adapted to be snugly inserted into the opening (21) of the I/O card (10), the projecting section (29) of the PC board (26) is electrically and mechanically engaged within the card edge connector (70) for communication between the computer and the corresponding peripheral.
