A connection-converting device (300) is used to connect an expansion card (110) to a portable electronic product (20), for example, a personal digital assistant which has a circuit board (100) and a card socket (120) mounted on the board. The expansion card is implemented with an M number of signal terminals (415), and the card socket is implemented with an N number of pins (150), wherein, the number of signal terminals is greater than the number of pins. The board is provided a P number of contact pads (250) thereon, wherein P is equal to M minus N. The connection-converting device (300) has an M number of signal pins (315) electrically engaging with the signal terminals (415), an N number of receptacle terminals (335) electrically connecting with the pins (150) and a P number of external contact terminals (350) electrically connecting with the contact pads (250).
