Abstract

The utility model comprises an insulating main body, a plurality of conductive terminals inserted in plug joint portion of the insulating main body, a slide groove disposed on one side of the plug joint portion, a push block disposed in the slide groove and provided with a guide groove for limited slide of a guide rod thereon, and a plurality of elastic components disposed between the push block and slide groove. A positioning elastic sheet is disposed on one side of the push block for engaging and positioning groove of a memory card, and forms an optimal configuration with the guide rod so that the contact acting force between the positioning elastic sheet and the guide rod is smaller than bearing force of the guide rod itself. When the memory card is inversely inserted by mistake, the memory card is pushed into the plug joint portion to make the positioning elastic sheet and the guide rod contact with each other on card withdrawing path. The guide rod is unlikely to deform or detach from the guide groove due to contact compression by the positioning elastic sheet.
