Card connector for PC cards

摘要

A card connector comprising a U-shape frame of a pair of guide arms of synthetic resin, a metallic bridge connecting the guide arms to each other to form a U-shape, and a connector part fit to the U-shape frame beneath the metallic bridge. A lever and a slider plate of an eject mechanism are mounted on the bridge. One of the guide arms is provided with an ejector button to be slidable thereon. In order to prevent the PC card from inserting into the card connector with a state where the PC card is reversed in front and rear and/or upside down, one of the guide arms is formed with a thin polarity key and the other of the guide arms is formed with a thick polarity key. Both the guide arms are symmetrically constituted except the polarity keys and are replaceable to each other. Further the card connector is provided with ground lugs each of which has a hook for engaging with a printed circuit board and a positioning portion for positioning said card connector at a desired standoff level above the printed circuit board.
