The technical solution of the utility model is: include pedestal, be provided with accommodation space in this pedestal, this pedestal one end is provided with the socket that communicates with accommodation space, is installed with the first terminal group, second terminal group and the 3rd terminal group on base bottom surface respectively; Slide block, this slide block is arranged in the accommodation space, and this slide block has the plural groove that can crisscross second terminal group, has rib on each groove simultaneously, the platform dual-side is extended with first contact part and second contact part respectively, being connected mutually between first contact part and pedestal has first flexible member, and there is second flexible member mutual the linking between second contact part and pedestal.

Above-mentioned the first terminal group is provided with for being compatible to xD memory card bank row;

Second terminal group is provided with for being compatible to SD memory card and MMC memory card bank row;

The 3rd terminal group is provided with for being compatible to MS memory card bank row;

Second terminal group includes plural contact site simultaneously, and each contact site is coated on each rib;

First flexible member and second flexible member are spring or elastic board chip;

The level height of slide block is higher than the first terminal group and second terminal group.

Advantage of the present utility model is: can avoid memory card to touch all the other interior terminal group of connector, reduce the wearing and tearing and generation elastic fatigue of memory card and terminal group; Can prevent that terminal group is rubbed by memory card, can carry out the purpose of memory card contact simultaneously to second terminal group, practical.
