The base has a first space for at least one set of terminals to be mounted therein, a second space with the card ejection mechanism mounted therein, and a spring leaf mounted in the second space. The card seat has a tongue. The tongue has a card-holding slot formed in a top of the tongue and mounted inside the first space of the base, and an engagement part formed on a bottom of the tongue and corresponding to the spring leaf of the base. When the card seat is inserted in the base, the engagement part of the tongue engages the spring leaf of the base for the card seat to be securely held by the base. When the card seat is removed from the base, the card ejection mechanism is pressed to squeeze the spring leaf of the base for the engagement part of the tongue to disengage from the spring leaf and the card seat can be ejected from the base. ## Claims ### Claim 1 A card connector comprising: a base having: an opening formed through a front of the base;
