Abstract: A card connector is configured for receiving a generally rectangular card therein. The card has contact pads and generally parallel first and second sides with a cut-away portion formed in the first side in proximity to a front end of the card. The cut-away portion includes a short length extending from the front end generally parallel to the first side, and a tapered shoulder part extending from the short length to the first side. The connector includes an insulative housing with first and second spaced apart sidewalls that define a cavity therein for receiving the card in an insertion direction. A tapered surface is provided adjacent the first sidewall to guide an improperly inserted card at an angle to the insertion direction and a second sidewall recess is formed in the second sidewall to permit entrance of a corner part of such improperly inserted card.
