Electrical card connector with improved card locking arm for holding an inserted card

An electrical card connector for insertion of a card with a depression defined on a lateral side thereof, comprising:

• an insulative housing defining a card receiving space and a side wall located at a lateral side of the card receiving space, the side wall comprising a resistance wall and a notch located forward the resistance wall;
• a plurality of contacts with contact portions extending into the card receiving space for mating with the card;
• a slider mounted on the side wall and comprising a first side surface attached to an inner side of the side wall, a second side surface opposite to the first side surface and a through hole extending through the first and the second side surfaces;
• and
• a locking arm fixed on the slider, the locking arm having a hook received in the through hole and an engaging portion moveable in the notch;
• wherein
• with insertion of the card into the card receiving space, the hook is deformable to lock with the depression of the card and the engaging portion is driven by the card to extend beyond the notch to finally abut against the resistance wall for preventing the card from withdrawing from the card receiving space.

An electrical connector comprising:

• an insulative housing;
• a metallic shell cooperating with the housing to define a card receiving cavity;
• a plurality of contacts disposed in the housing with contacting sections extending into the card receiving cavity;
• a side arm located on one lateral side of the card receiving cavity;
• a slider moved along an inner side of the side arm in a front-to-back direction and defining a through hole in a lateral direction, a locking arm attached to the slider and laterally deflectably located in said through hole;
• wherein
• said side arm defines a cutout to allow the locking arm to outwardly deflectably move when an electronic card is inserted into the card receiving cavity;
• wherein
• said slider includes a top face to protectively hide the locking arm thereunder, and the locking arm is allowed to be only laterally assembled to the slider.
