Referring to the second to third figures, the shielding shell 4 includes a top wall 41 and two side walls 42 extending downward from the top wall 41. The top wall 41 has two resilient portions 412 that extend downwardly into the slot 12. The two side walls 42 are respectively provided with a fastening hole 420 corresponding to the fastening block 113 of the insulative housing 1 and a resisting portion 421 extending inwardly corresponding to the yielding portion 111 of the side portion 11. The top wall 41 is further provided with a flange formed by downwardly vertical punching and an opening 411 formed when the flange is formed. The flange includes a bent portion 4101 and a self-bending portion 4101 connected to the inner edge of the opening 411. a limiting portion 4102 extending downwardly, the limiting portion 4102 is vertically sheet-shaped, parallel to the side wall 42 and spaced apart from the side wall 42, and the two sides of the limiting portion 4102 are barbed, the limit The portion 4102 enters the recess downwardly and presses against the pivot end 331, and the barb interferes with the inner side wall of the recess to restrict the upward movement of the limiting portion 4102. The abutting portion 421 is provided with a chamfered free end 4210, and the free end 4210 is pressed against the sliding end 333 to prevent the guide rod 33 from being ejected.

Referring to the first to sixth figures, when the electronic card connector 100 is assembled, the slider 31 of the card ejecting mechanism 3 is first received in the receiving slot 110, and the spring 32 is sleeved at the side 11 at one end. The other end of the positioning column 1101 is sleeved on the holding column 312 of the slider 31. Secondly, after the sliding end 333 of the guiding rod 33 is installed inside the common rail 314, the sliding end 333 is used as a fulcrum and is rotated downward. The guiding rod 33 is such that the pivoting end 331 of the guiding rod 33 is mounted downward in the receiving groove 1121 and extends from the side of the groove. Finally, the shielding shell 4 is wrapped on the outside of the insulating body 1 on the side wall 42. The latching hole 420 is fastened to the latching block 113 on the outer side of the insulative housing 1 , and the resisting portion 421 is pressed against the guiding rod 33 over the retaining portion 111 on the side portion 11 to prevent the guiding rod 33 from moving outward. The limiting portion 4102 of the flange is downwardly inserted into the recess, the front portion is located in the limiting slot 1122, and the rear portion passes through the receiving slot 1121 and is pressed against the pivoting end 331 in the up and down direction, and the limiting slot 1122 blocks The limiting portion 4102 is swayed in the left-right direction, and the bottom portion of the receiving groove 1121 and the limiting portion 4102 located in the receiving groove 1121 are surrounded by a pivot hole. Pivoting end 331 to limit the pivoting hole is rotated to ensure that the card, the card back smoothly.

When the electronic card is inserted, the rear end of the electronic card abuts against the abutting portion 313 of the slider 31, thereby driving the slider 31 to move along with the electronic card. Accordingly, the sliding end 333 of the guiding rod 33 is gradually sliding from the common rail 314 to the card. The track 3112, during which the abutting portion 421 against the guiding rod 33 is not pushed beyond the outer side of the electronic card connector, and the rear sliding end 333 slides from the feeding card track 3112 into the locking card track 3114. The guide rod 33 and the spring 32 are balanced against the slider 31, and the electronic card is inserted into the correct position. When the card is retracted, the user pushes the electronic card again, so that the sliding end 333 enters the eject track 3113 from the lock card track 3114, and the spring 32 forces the slider 31 to retreat until the sliding end 333 returns to the initial position of the common track 314, and the card is retracted. . During the process of inserting and ejecting the card, when the sliding end 333 of the guiding rod 33 slides in the heart-shaped groove 311, since the heart-shaped groove 311 has a contraction distance, the fitting surface abuts against the guiding rod 33. 315 and the auxiliary surface 316 of the heart-shaped cam 3111 are also synchronously retracted, making a position to enable the guide rod 33 to abut against the first inner wall of the heart-shaped groove 311, and to achieve an integral position inward movement function, thereby When the guide rod 33 slides on the first inner wall, the distance at which the abutting portion 421 is pushed out by the guide rod 33 does not exceed the distance at which the guide rod 33 is pushed up when the second rod is slid. The first inner wall of the common rail 314 is not retracted in the present embodiment, and may be simultaneously retracted in other embodiments. Therefore, it can be ensured that the abutting portion 421 of the abutting guide 33 does not deform outward beyond the outermost side of the side wall 42 of the shielding case 4, thereby not affecting the overall planar layout of the circuit board 5. At the same time, the overall size of the slider 31 is substantially unchanged, and the overall strength is ensured.

In summary, this creation is in line with the new patent requirements, and the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and those who are familiar with the skill of the present invention are equivalent to the equivalent modifications or changes made by the spirit of the present creation.
