Abstract: An electronic card connector includes a slider operable between a card-inserting mode and a card-releasing mode, and a positioning mechanism. The positioning mechanism includes a positioning member, a biasing element, and a second engaging element. The positioning member has a first sliding face, a second sliding face cooperating therewith to define a first corner with the first sliding face, and a first engaging element. In the card-inserting mode, operation of the slider results in relative movement between the second engaging element and the positioning member along a first path such that the second engaging element abuts against and slides along the first sliding face by the urging action of the biasing element, and turns around the first corner to engage releasably the first engaging element.
