Abstract
An electronic card coupler comprises an insulating body, a plurality of conductive terminals fixedly held on the insulating body and a covering shell connected on the insulating body by buckling. The insulating body comprises an inserting and connecting surface positioned at the front end, housing space and first and second side walls. The housing space is backwards arranged in a concave manner from the inserting and connecting surface and is used for housing electronic cards. The first and second side walls are positioned at the two sides of the housing space and are communicated with the housing space. The first side wall is provided with a metal spring plate. The metal spring plate is provided with a latch part and a first contact surface which is close to the inserting and connecting surface, extends into the housing space in a bent manner and is positioned at one side of the housing space. Therefore, the coupler ensures the smoothness when the electronic cards are inserted in the beginning and ensures stable contact between the electronic cards and the conductive terminals.
