A card connector has a housing with a base and a side rail extending from the base to define a card-insertion cavity. A plurality of conductive terminals are supported by the housing and extend at least partially into the card-insertion cavity for contacting a card inserted into the card-insertion cavity. A push-push style card locking and ejection mechanism retains the card in the card-insertion cavity upon a first push and which ejects an inserted card upon a second push. The mechanism includes a slide member positioned for slidable movement on the side rail and a biasing member contacting the slide member for selectively exerting an ejection force on the slide member. The slide member includes a slide surface that slides along a guide surface of the side rail. A damping material is interposed between the slide member slide surface and the guide rail guide surface for retarding movement of the slide member on the side rail in response to an ejection force from the biasing member.
