[0017] Ginseng Figures 1 to 6 As shown, the utility model discloses a card edge connector 100, including a longitudinally extending insulating body 10, a plurality of conductive terminals 20 fixed to the insulating body 10, and a top clamp 30. The insulating body 10 is provided with a slot 11 for inserting an electronic card. The top clamp 30 is connected to one longitudinal end of the insulating body 10. The card edge connector 100 further includes a handle lever 40. A through hole 41 and a flange 31 that are mutually locked and matched are provided between the handle lever 40 and the top clamp 30 to fix the handle lever 40 on the top clamp 30. When the handle lever 40 is pulled, the handle lever 40 drives the top clamp 30 to move, so that the top clamp 30 pushes the electronic card.

[0018] Ginseng Figure 1As shown, the flange 31 and the through hole 41 are both polygonal structures, which can stabilize the handle puller 40 on the top clamp 30. When the user applies force to the handle puller 40, the polygonal structure can generate torque in multiple directions, which not only saves the user's effort, but also achieves a stronger connection force between the handle puller 40 and the top clamp 30. The flange 31 is set on a columnar portion 32, and the direction in which the columnar portion 32 extends is basically consistent with the direction in which the through hole 41 penetrates. Therefore, the through hole 41 can slide in any direction on the columnar portion 32. When not in use, the user can remove the handle puller along the direction in which the through hole penetrates without using external tools.

[0019] Ginseng Figures 1 to 4 As shown, the top clamp 30 is pivotally connected to the insulating body 10. Figure 2 As shown, a fixing platform 12 is integrally extended from one end of the longitudinal direction of the insulating body 10. The fixing platform 12 penetrates in a vertical direction perpendicular to the longitudinal direction and forms a movable groove 13. The top clamp 30 is received in the movable groove 13 and pivots inside. Figure 3 As shown, the top clamp 30 includes a main body 33, a top clamp 34 connected to the main body 33, and a first pressing portion 35 located above the top clamp 34. The top surface of the first pressing portion 35 is provided with a first pressing surface 351, and the first pressing surface 351 is provided with a rib 352 for pressing by a finger, wherein the handle puller 40 is assembled on the first pressing portion 35. The handle puller 40 is made of plastic in one piece, and is provided with a holding portion 42, a handle portion 43 and an operating portion 44 in sequence in a direction away from the first pressing portion 35. The holding portion 42 is connected to the first pressing portion 35, and the handle portion 43 and the operating portion 44 are provided in sequence. The holding portion 42 is connected to the first pressing portion 35, and the handle portion 43 and the operating portion 44 are provided in sequence. Figure 5 As shown in FIG. 4 , the holding portion 42 is attached to one side of the first pressing portion 35. Figure 1 As shown, the holding portion 42 is provided with a through hole 41, and a columnar portion 32 is protruded from one side of the first pressing portion 35. The columnar portion 32 has a polygonal flange 31 around it, which matches the through hole 41, so that the holding portion 42 is sleeved on the first pressing portion 35. Due to the sleeve connection, it is also convenient to remove the handle puller 40 when not in use. In addition, the handle puller 40 is a sleeve-type handle structure, which is longer in size, which is convenient for users to use. Figure 6 It can be seen that the length of the handle wrench 40 is at least half of the longitudinal length of the insulating body 10. The handle portion 43 extends upward from the holding portion 42, and the operating portion 44 extends in a direction away from the electronic card (not shown) and has a second pressing portion 45. The top surface of the second pressing portion 45 is provided with a second pressing surface 451, and the second pressing surface 451 is provided with a rib 452 for pressing. A through groove 46 is provided on one side of the operating portion for applying force and pressing with a tool. The user can apply force and press through the first pressing portion 35 or the second pressing portion 45 or use a tool to rotate the ejection member 30 to eject the electronic card (not shown) as needed.

[0020] Ginseng Figure 6As shown, the insulating body 10 is provided with a guiding inclined surface 14, and the bottom surface of the top clamp 30 can rotate along the guiding inclined surface 14. The top clamp 30 is pivotally connected to the insulating body 10, and a limiting portion 36 is provided at the bottom thereof to limit the rotation angle of the top clamp 30, and finally abuts against the insulating body 10, which can prevent the top clamp 30 from excessive rotation.

[0021] Ginseng Figure 2 As shown, the card edge connector 100 also includes a shielding shell 50, which is provided with a plurality of pins 51. A plurality of protrusions 15 extend outward from the bottom edge of the insulating body 10, and the protrusions 15 are provided with through holes 16 penetrating in a vertical direction perpendicular to the longitudinal direction. The pins 51 are inserted into the through holes 16 to limit the shielding shell 50. In addition, the outer surface of the insulating body 10 is recessed in the direction of the slot 11 to form a limiting groove 17. The shielding shell 50 is torn with a plurality of spring pieces 52, which are bent in the direction of the slot 11 and abut against the inner wall surface of the limiting groove 17 to limit the shielding shell 50, thereby fixing the shielding shell 50 on the insulating body 10.
