Abstract

The invention provides an electronic card connector positioned on a printed circuit, which includes an insulation body, a mask shell installed on the insulation body and a terminal model group detaining a conductive terminal installed below the insulation body. The mask shell and the insulation body form a detaining space for inserting the electronic card. The insulation body is provided with a detaining part which detains the terminal model group. The contact surface between the terminal model group and the printed circuit is provided with a positioning device and the terminal model group is directly positioned and welded on a printed circuit board. The insulation body and the terminal model group are designed separately and the terminal model group can be welded on the printed circuit board in advance. The mask shell and the insulation body are combined and then positioned on the printed circuit board. Therefore, no welding is needed between the insulation body and the printed circuit board and the warping of the insulation body can be effectively avoided thereby.
