Patent attributes
A card edge connector that allows the insertion of an electric card includes an insulating body, a plurality of terminals, and two metallic pieces. Each of the two metallic pieces includes a substrate, an elastic arm connected to the substrate, and a locking portion connected to the upper edge of the free end of the elastic arm. The locking portion has a curved bottom surface and a smooth bottom surface. The smooth bottom surface is adjacent to the curved bottom surface. When locked, the curved bottom surface of the locking portion presses and locks the electric card. When the curved bottom surface loosens due to vibrations of the electric card, the smooth bottom surface of the locking portion presses and locks the electric card firmly. Therefore, the locking effect is increased, and the electric card is prevented from loosening and bounding upwardly.
