The tray 5 is mounted on the insulative housing 1 and slides back and forth in the receiving portion receiving slot 13. The guiding surface 15 is disposed so that the tray 5 can be smoothly inserted into the receiving slot 11, and finally the metal housing 6 is covered on the insulative housing 1. Specifically, a plurality of the latching blocks 16 are respectively inserted into a slot 68, and the protruding portion 412 is slidably mounted in the through hole 65, and the bent portion 661 of the elastic strip 66 abuts against the slot 413. With the position of the positioning pusher 41, the bump 671 of the elastic piece 67 abuts against the sliding block 43 to prevent the sliding block 43 from shaking when sliding along the sliding groove 142. When the card is inserted, the tray 5 is pulled out of the insulative housing 1 , the electronic card 7 is placed in the mating slot 521 of the carrying portion 52 , and then the tray 5 is pushed into the receiving slot 13 , and the contact portion 34 of the conductive terminal 3 passes through the mating slot 521 and The electronic card 7 is in contact to achieve an electrical connection. When the card is ejected, the push-up lever 442 of the pushing member 44 can be pushed back through the connecting hole 5111 to push the push rod 41 backward. The ball 42 slides in the connecting groove 133 by the push rod 41, thereby pushing the sliding block 43 to slide the sliding block 43 forward in the sliding slot 142, and the sliding portion 432 slides forward to abut against the front slot of the long slot 1031. The wall, the chamfer 4331 of the pushing portion 433 contacts the connecting wall 522 of the tray 5 and pushes the tray 5 to move forward, so that the tray 5 is forwarded a certain distance forward, and then the grip portion 51 is pulled out of the insulating body 1 The storage slot 13 is received, and the electronic card 7 is taken out. As described above, the present card connector has a design of the card ejecting mechanism 4 by a push rod 4, a plurality of balls 42, a sliding block 43, and a pushing member 44, thereby greatly reducing the width of the card connector, thereby Conducive to the miniaturization of the card connector.
