1. A four-in-one memory card insertion port including an upper terminal seat and a lower terminal seat;

  • whereinthe upper terminal seat is made of insulating material;

    a front end surface thereof has a plurality of inserting holes;

    each inserting hole is installed with a first conductive terminal which protrudes to a front and a rear ends of the upper terminal seat;

    a front end of each first conductive terminal has a first top portion for conducting a memory stick (MS) memory card; and

    the lower terminal seat is a rectangular seat and has two alternatively arranged slots;

    each slot is installed with a second conductive terminal which extends to a rear end of the seat and has 22 pins;

    a front end of each conductive terminal has a second top portion;

    thereby, two banks of second top portions resist against a smart media (SMC) memory card having contact points;

    front sides of a plurality of twenty two second conductive terminals are installed with nine slots which extend to the front end thereof;

    a third conductive terminal is installed in a groove, which extends forwards;

    a front end of the third conductive terminal has a third top portion so as to resist against a secure digital(SD) memory card with nine conductive points, while seven conductive points are used to contact a multi-media(MMC) memory card;

    whereby the upper terminal seat and lower terminal seat are welded to a circuit board;

    the third conductive terminals at the front end of the upper terminal seat are installed at a rear upper side of the lower terminal seat so as to form a four-in-one memory card insertion port for being inserted by the memory stick (MS), smart media (SMC), secure digital (SD) and multi-media (MMC) memory card.
