Claim:
1. An electronic card connector provided on a circuit board, the electronic card connector comprising: a metal shell provided on the circuit board, the metal shell cooperating with the circuit board to define a slot, the metal shell having a top plate which is spaced apart from and faces the circuit board, two side plates which are respectively connected to two sides of the top plate and face each other, and two limiting arms which are respectively bent from two end edges of the two side plates adjacent to an entrance of the slot and perpendicular to the top plate and extend toward each other, each limiting arm being spaced apart from the top plate and having a side stopping surface toward the other limiting arm and a front stopping surface toward the outside of the slot; a terminal block provided on the circuit board and positioned in the slot; and a tray inserted into and ejected from the slot via the entrance of the slot along an inserting-ejecting direction and used to carry an electronic card to be received in the slot so as to allow the electronic card and the terminal block to be electrically connected, the tray having an insertion end which first enters the slot and two receiving portions which are respectively parallel to two sides of the inserting-ejecting direction, the two receiving portions respectively corresponding to the two limiting arms, so that when the tray is properly inserted, the tray entering into the slot without blocking of the two limiting arms, the tray further having two interference oblique surfaces respectively parallel to the two sides of the inserting-ejecting direction and adjacent to the insertion end, a distance between the two interference oblique surfaces gradually increasing along a direction away from the insertion end; when the tray is improperly inserted under a state that the tray is turned upside down, each interference oblique surface abutting against a boundary between the side stopping surface and the front stopping surface of the corresponding limiting arm, so that the tray cannot enter into the slot.
