Abstract: An electrical card connector for holding a card with a notch defined on a lateral side thereof, includes an insulative housing, a number of contacts and a push-push mechanism. The push-push mechanism includes a slider movable between an initial position and a final locking position along a front-to-back direction, a spring abutting against the slider and an elastic locking arm having a card lock for locking with the notch of the card. The slider further includes a rigid protrusion to engage with the notch of the card. The rigid protrusion not only helps the card lock hold the card when the slider is located at the final locking position, but also helps the card lock prevent the card from flying out of the card receiving space when the slider moves from the final locking position back to the initial position.
