Card edge connectors are widely used electrical connectors in electronically placed devices for mounting additional printed circuit cards to expand the performance of such electronic devices. In recent years, due to the trend of portable products, electronic devices have faced a significant reduction in volume. Therefore, electronic components and connectors mounted in electronic devices must produce a smaller (four) product to meet the needs of small electronic devices. In general, the card edge connector is provided with an exit mechanism 1 to safely remove the card edge connection n to accommodate the (four) brush circuit card. Flash lock/push-up members have been widely used in exit mechanisms for latching and exiting from the card edge connector: the circuit card is swiped. As shown in Figures 1A and 1B, an exemplary challenge/pushing member! A latch 胄12 for exiting the printed circuit card 2, a latch 胄12 for locking the printed circuit card 2, and for pivoting the flash lock/pushing member 1 to exit the printed circuit card 2 one of the actuation units 13. When the brush circuit card 2 is inserted, the leading edge 21 of the printed circuit card 2 is mounted above the upper surface Π1 of the push top 11. Searching for the traditional latching/pushing member i you consist of plastic material. In order to ensure that the push top U has sufficient strength during the exit operation, the push top u must have a sufficient thickness, which would be 4. 4. [S] 201119156 Adding the leading edge 21 of the printed circuit card 2 and the printed circuit board 3 The distance between the upper surfaces, or the mounting height of the printed circuit card 2, hinders the possibility that the final height of the inserted printed circuit card 2 is further lowered. As shown in Fig. 2, U.S. Patent (4) discloses a latching member 4 from a metal blank: pressed and formed. The latch member 4 includes two resilient cantilevers 41. However, the suspensions 41 have sufficient strength to effectively fix-insert printed circuit cards. In addition, placed on the bottom wall (four) joint

Further, each end tower portion 711 may include A strut member 7114, shown in Fig. 8, Fig. and circle 11, is aligned with the card slot 712 to limit movement of the printed circuit card 6 in the longitudinal direction of the insulative housing 71. As shown in Figures 12 and 13, The two side edges are substantially spaced from one another to accommodate the strut member 7114 therebetween. When the printed circuit card 6 is not inserted, the latch/ejector member 73 is in a tilted or unlocked position. At this time, the push top m is located below the card slot 712, waiting to touch the leading edge 611 of the printed circuit card 6. During the process of connecting the printed circuit card (10), the 201119156 s edge 611 pushes the push top 73 downward, and the arcuate edge 73 j j moves against the leading edge 611. If the insertion force is sufficiently large, the stamping is convex. The 卩 739 can pass through the individual bumps 7113. After passing, the door lock/pushing member 73 can continue to rotate until the first edge portion 732 enters the corresponding recess 63 1 to lock the printed circuit card 6. Referring to FIGS. 14 and 15, after the printed circuit card 6 is mounted, the printed circuit card 6 is seated on the push top 731 and is located at the side edge portion 63 between the recess 631 and the J edge 611. A portion is surrounded by the side edge portion 6' of the first edge portion 732 and the push top portion 731. Since the flash lock/eject member 73 is composed of a stamped metal plate, the stretchable strength is much higher than that of the plastic material, so that the thickness of the push top 731 can be greatly reduced. Further, a thin push top 731 can still withstand external forces without permanent deformation. Therefore, the mounting height of the printed circuit card 6 can be greatly reduced by the thickness of the push top 73. In summary, the card edge connector of the present invention includes a latch/pushing member 73 formed of a stamped metal plate and having a thin push top 731 such that the printed circuit card 6 is mounted at a height Can be drastically reduced. Moreover, the joint of the latch/ejector member 73 is not located at the push top i, so the risk of the push top 731 being cracked can be ruled out. The technical contents and technical features of the present invention have been disclosed as above, and those skilled in the art can still make various substitutions and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the present invention should be construed as being limited by the scope of the appended claims. -11- [S] 20ιΠ9156 [Simple description of the drawings] Fig. 1B is a flash lock/pushing member of a conventional technique; Fig. 2 is a latching member of the prior art; Fig. 3 is an embodiment of the present invention FIG. 4 is a schematic diagram showing the connection of a card edge connector, a printed circuit board, and a printed circuit card according to an embodiment of the present invention; Figure 6 is a partial enlarged view of an insulating case according to an embodiment of the present invention; Figure 7 is a partial enlarged view of a latch/ejector member according to an embodiment of the present invention; 8 is a schematic view of an end tower portion according to another embodiment of the present invention; FIG. 9 is a cross-sectional view of the γ_γ cut surface line of FIG. 8; FIG. 10 is a partial enlarged view of a card edge connector according to an embodiment of the present invention; FIG. 13 is a partial enlarged view of a card edge connector according to an embodiment of the present invention; FIG. 13 is a partial enlarged view of a card edge connector according to an embodiment of the present invention; Figure 14 is a card according to an embodiment of the present invention Partial enlarged view of the connector; local lines 15 and the card edge connector of the embodiment of an enlarged view of an embodiment of the present invention.
