Abstract:
1. A card edge connector, used for connecting an electronic card to a printed circuit board and comprising: an insulative housing defining a front face, a mounting surface and a receiving slot running through the front face and extending along a longitudinal direction with a key disposed therein; and a plurality of conductive terminals retained in the insulative housing and each defining a contacting arm extending into the receiving slot along a mating direction perpendicular to the longitudinal direction and a soldering portion extending outside of the insulative housing; wherein the contacting arm of each conductive terminal defines a free end portion located in the receiving slot and with a contacting portion disposed thereon, the thickness of the free end portion in a vertical direction perpendicular to both the longitudinal direction and the mating direction is smaller than the thickness of other parts of the contacting arm; wherein the insulative housing defines a first sidewall and a second sidewall located in opposite sides of the receiving slot and a base portion connecting the first and second sidewalls, the conductive terminals include a plurality of first terminals located in the first sidewall and a plurality of second terminals located in the second sidewall; wherein the first terminal defines a retaining portion fixed in the first sidewall and the soldering portion extending outside of front face of the insulative housing, the second terminal defines a retaining portion fixed in the base portion, the contacting arm of the first terminal extends into the receiving slot from the retaining portion and the soldering portion of the second terminal extends outside of the rear face of the insulative housing; wherein a front edge of an inner surface of the second sidewall is an inclined surface, and a front edge of an inner surface of the first sidewall is an recessed surface; wherein the retaining portion of the second terminal is higher than the contacting arm of the first terminal but lower than the contacting arm of the second terminal in the vertical direction.
