Electrical card connector for different size cards

An electrical card connector to be connected to a first electrical card and a second electrical card, which is thinner and narrower than the first electrical card, first ends of the first and second electrical cards being formed with connection points arranged in the same manner, the electrical card connector comprising:

• 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, wherein:
• a transversal partition baffle is disposed below a front end of the top surface of the upper cover;
• each of two sides of the partition baffle is formed with a longitudinal 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 the first electrical card is inserted into the first slot from the first inserting port, the connection points of the first electrical card are in direct contact with the first terminals;
• and
• when the second electrical card is slantingly inserted from the second inserting port, the connection points of the second electrical card are lowered and thus in direct contact with the first terminals.
