[ detailed description ] embodiments

Referring to fig. 1 to 6, the card connector 100 of the present invention includes a base 1, a plurality of conductive terminals 2 fixed on the base 1, a shielding shell 3 covering the base 1 to form an insertion space 30 with the base 1, and a card ejecting mechanism 4. The plug space 30 is used for inserting an electronic card (not shown) or a card holder 5 on which the electronic card (not shown) is arranged.

The conductive terminal 2 is integrally formed on the base 1, and the conductive terminal 2 has a contact portion 21 protruding upwards into the insertion space 30. The card ejecting mechanism 4 includes a push rod 41 disposed at a side of the base 1 and a cam rod 42 disposed at a front end of the base 1 and cooperating with the push rod 41 to pivot backward, and the push rod 41 and the cam rod 42 are preferably made of a metal material. The cam rod 42 includes a positioning section 421 positioned on the push rod 41 and an abutting section 422 obliquely arranged with the fixing section 421, and the abutting section 422 has an abutting surface 4221 for abutting against the front end surface 50 of the electronic card or card holder 5. The upper end of the push rod 41 is recessed from the top to the bottom to form a mounting groove 411 adjacent to the front end, the fixing section 421 is mounted on the mounting groove 411 from the top to the bottom to make the cam rod 42 and the push rod 41 linked, and the shielding shell 3 is mounted on the base 1 from the top to the bottom to fix the cam rod 42 on the push rod 41. When the pusher 41 pushes forward, the cam lever 42 pivots backward, thereby pushing back the electronic card (not shown) or the card tray 5. The card connector 100 further includes a metal frame 6 integrally formed on the periphery of the base 1, the upper end surface 11 of the front end of the base 1 protrudes to form a pivot 111, the cam lever 42 is provided with a receiving hole 423 for receiving the pivot 111 therein, the metal frame 6 is provided with a reinforcing part 61 bent upward at a position corresponding to the pivot 111 and formed in the pivot 111, and the reinforcing part 61 is used for increasing the structural strength of the pivot 111 and preventing the pivot 111 from being broken when the cam lever 42 pivots.

In order to increase the distance that the electronic card (not shown) or the card holder 5 is pushed back by the cam rod 42, the abutting surface 4221 is concavely provided with a holding groove 4222, and the front end surface 50 of the electronic card (not shown) or the card holder 5 is convexly provided with a convex block part 51 which is accommodated in the holding groove 4222. When the cam rod 42 is pushed forward by the push rod 41 and pivoted backward, the protruding portion 51 is disengaged from the receiving groove 4222, and the cam rod 42 pushes against the protruding portion 51, so that the distance that the electronic card (not shown) or the card holder 5 is pushed backward by the cam rod 42 can be increased. Specifically, in the present invention, the insertion space 30 is used for inserting the card holder 5, the card holder 5 is preferably made of a metal material, an electronic card (not shown) is carried on the card holder 5, the protruding block 51 protrudes from the front end surface 50 of the card holder 5, and of course, the protruding block 51 may be disposed on the front end surface of the electronic card (not shown) when the card connector is used for inserting only the electronic card (not shown). The accommodation groove 4222 has a guide side surface 4223, and the side surface of the protruding block part 51 is a guide side surface 511 matched with the guide side surface 4223. The guiding side 4223 abuts the free end 424 of the abutting section 422, and the guiding side 4223 is smoothly transited to the abutting surface of the free end 424 of the abutting section 422. When the cam lever 42 is pushed forward by the push rod 41 to pivot backward, the protruding portion 51 is disengaged from the accommodation groove 4222 and is abutted by the free end 423 of the abutting section 422, thereby increasing the distance by which the card holder 5 is abutted backward by the cam lever 42.
