Claim:
A card-in/out device for an electrical connector, the electrical connector having a base composed of a bottom seat and an upper cover covering over the bottom seat, the card-in/out device comprising: a sliding slot structure, which is disposed in the base and has a circulation path, one end of the circulation path being formed with a concave first positioning point, the other end of the circulation path being formed with an initial second positioning point, a bottom surface of the sliding slot structure being formed with a plurality of one-way stoppers such that a one-way circulation from the second positioning point to the first positioning point and then to the second positioning point is formed; a pushing piece, which is disposed in the base and may slide back and forth relative to the upper cover, wherein the pushing piece is formed by pressing and bending a metal plate and comprises: a longitudinal plate extending in an inserting direction of the base and comprises at least one push portion which may be pushed by an inserted electrical element in the inserting direction; a horizontal plate integrally connected with the longitudinal plate, the horizontal plate being bent into a horizontal state from a top of the longitudinal plate toward one side; and a guiding rod having one end connected to the horizontal plate or the longitudinal plate, and the other end engaged with the sliding slot structure of the base such that the guiding rod can slide back and forth along the circulation path; and an elastic member for providing an elastic force for moving the pushing piece, which is moved from an original position into the base, back to the original position.
