An electrical card connector includes: a plastic base having one row of first terminals and a first slot; and an upper cover, which has a top surface and covers over the plastic base. A partition baffle is disposed below the top surface of the upper cover. Each side of the partition baffle is formed with a side portion. A first inserting port is formed below the partition baffle. A second inserting port is defined and enclosed by the partition baffle, the two side portions and the top surface of the upper cover. When a first card is inserted into the first slot from the first inserting port, connection points of the first card are in direct contact with the first terminals. When a second card is slantingly inserted from the second inserting port, connection points of the second card are lowered and thus in direct contact with the first terminals.
