An electrical card connector (100) includes an insulating housing (2), a metal shield (1) covering the insulating housing for defining a card receiving space therebetween, a printed circuit board (PCB) (5), an insulator (3) assembled on the PCB and a plurality of terminals (4) received in the insulator. The insulating housing defines a cutout (210) at a rear part thereof and the cutout communicates with the card receiving space. The PCB has a smaller size than the insulating housing and is received in the cutout. The PCB is fused with the insulating housing.
