    • 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).
    • 连接转换装置(300)用于将扩展卡(110)连接到便携式电子产品(20),例如具有安装有电路板(100)和卡插座(120)的个人数字助理 在板上。 扩展卡由M个信号端子(415)实现,并且卡插槽由N个引脚(150)实现,其中,信号端子的数量大于引脚数。 该板上设置有P个接触焊盘(250),其中P等于M减去N.连接转换装置(300)具有与信号端子(415)电接合的M个信号引脚(315) ),与引脚(150)电连接的N个插座端子(335)和与接触焊盘(250)电连接的P个外部接触端子(350)。
