Claim:
A dual usage memory card connector comprising: an electrically insulative housing, said housing comprising a forwardly extended receiving open chamber, which fits a MS (Memory Stick) memory card, a top opening, two spring arms suspended at two opposite lateral sides thereof and movable between a first position for holding a MS Duo memory card in said receiving open chamber and a second position for holding a MS memory card in said receiving open chamber, said spring arms each having a front clamping tip projecting into the receiving open chamber, and two retaining blocks disposed at the two opposite lateral sides in front of said spring arms; a plurality of terminals respectively mounted in said housing and extended to a rear side of said housing; and a metal top cover covered on said housing, said top cover comprising two retaining holes disposed at two opposite lateral sides thereof and respectively coupled to the retaining blocks of said housing, a transversely extended top suspension spring plate, a curved holding down portion forwardly extended from said top suspension spring plate and projecting through said top opening into the inside of said front receiving open chamber for holding down a memory card in said front receiving open chamber, and two limiters respectively formed integral with two distal ends of said top suspension spring plate and adapted to hold said spring arms in said first position; wherein when inserted a MS Duo memory card into said receiving open chamber, said limiters hold said spring arms in said first position, said spring arms and the curved holding down portions of said spring plate of said top cover hold down the inserted MS Duo memory card in contact with said terminals; when inserted a MS memory card into said receiving open chamber, said limiters are forced by the inserted MS memory card to disengage said spring arms from said first position, enabling said spring arms to move to said second position by spring power thereof, and the curved holding down portions of said spring plate of said top cover hold down the inserted MS Duo memory card in contact with said terminals.
