Abstract: A dual-card connector has an insulating housing. The insulating housing has a top surface which defines a first surface and a second surface, the second surface is lower than and adjoins the first surface. A plurality of first and second terminals is respectively mounted to the first and second surface. A shell assembled with the insulating housing has a first cover, a connecting portion extending downwards from an edge of the first cover, and a second cover extending opposite to the first cover from a lower portion of the connecting portion such that the second cover is lower than the first cover. The connecting portion is supported on a place of the first surface adjacent to the second surface; the first and the second cover are respectively disposed above the first and second surface to form a first insertion space and a second insertion space therebetween.
