Electrical card connector with stop member for preventing card from flying off during ejecting

An electrical card connector comprising:

• an insulative housing defining a card receiving space and a side wall located at a lateral side of the card receiving space;
• a plurality of contacts with contacting portions extending into the card receiving space for mating with a card;
• a push-push mechanism comprising a slider slidably mounted on the side wall, an elastic member for driving the slider along a card insertion/extraction direction and a locking arm fixed to the slider, the slider being slidable simultaneously with the card, the locking arm comprising a hook protruding into the card receiving space for locking the card, an inclined guiding portion extending from the hook for guiding insertion of the card and a support portion bent outwardly and forwardly from the guiding portion;
• and
• a stop member for mating with the locking arm;
• wherein
• (i) the hook locks with a notch of the card when the card is fully inserted into the card receiving space at a card locking position, and the support portion resists against the side wall to prevent the card from withdrawing from the card receiving space if pulling out the card under such card locking position;
• and
• (ii) when the card is further pushed by an external force during ejecting and the external force disappears immediately, the card will be ejected past a release position where the locking arm is restricted by the stop member to prevent releasing the card.

An electrical card connector for use with an electronic card having a notch in one side, comprising:

• an insulative housing;
• a metallic shell assembled to the housing and cooperating with the housing to define a receiving space therebetween in a vertical direction;
• a plurality of contacts disposed in the housing with contacting sections extending into the receiving space;
• an ejection mechanism for ejection of the card, including:
• a slider back and forth moveable along a front-to-back direction with regard to the housing and equipped with a hook thereon for locking into the notch of the electronic card, said slider defining a rear position with regard to the housing where the card is securely locked by the hook and is essentially well mated with the contacts, a release position in front of the rear position, where the card is unmated with the contacts and is slightly locked by the hook while being able to be unlocked via an external withdrawal force applied thereon, and an position in front of the release position, where the card is unmated with the contacts and is securely locked by the hook;
• and
• a spring device providing a forward force and essentially urging the slider back to the release position at least when the slider is moved between the release position and the rear position.
