The utility model discloses a card connector, card connector insulator has the loading end that is used for bearing the electron card, conductive terminal includes that the fixed part reaches certainly the elastic arm that the fixed part extends. Linking arm that the elastic arm has an adjacent setting is with the contact arm and be connected the connecting portion of contact arm and linking arm, the both ends of contact arm all are not higher than said loading end setting, the projection that makes progress in the middle part of the contact arm is formed with and is higher than the loading end for and the contact site that connects relatively of butt joint terminal. Adopt the utility model discloses a card connector can avoid when the plug of electron card conductive terminal to be collapsed by the collision of electron card is crowded to when the extrusion that receives the electron card said conductive terminal's elastic arm can slide to both ends are flexible, and the structure is more stable, effectively improves card connector's life.
