Abstract: An electrical card connector for receiving an integrated circuit card comprises an insulative housing having a base, left and right side walls, and a rear wall to commonly define a rectangular receiving space therebetween, an ejecting member disposed adjacent the right side wall and within the receiving space, the ejecting member including a slider defining a locking head engageable with a recess defined on the card, and a driving end proximate to the rear wall; a shell assembled onto the insulative body for covering a top face thereof. A partition wall extends forward with a distance from the rear wall to partly separate the receiving space into a first region for the card, and a second region for the ejecting member. The slider has at least a portion engaging the partition wall to prevent rotation of the slider when the card is locked in an operation position by the slider.
