AI Technical Summary
Existing card connectors have the problem of wasted space in the lateral width, especially due to the increased width caused by the sequential arrangement of the clamping spring arms and push rods in the lateral direction.
A card connector was designed in which the push rod of the card ejection mechanism is placed above the clamping spring arm, changing the way the clamping spring arm and the push rod are arranged sequentially in the lateral direction. Through the structural optimization of the push rod limiting component and the clamping spring arm, the lateral space occupied by the push rod in the card cover assembly is reduced.
This effectively reduces the lateral width of the card connector, optimizes space utilization, and improves the product's compactness.

Abstract
Claims
1. A card connector, comprising a terminal module, a card cover assembly disposed above the terminal module, and a card holder that pushes between the card cover assembly and the terminal module, the card cover assembly comprising a shielding housing, a terminal group, an insulating body integrally formed with the terminal group on the shielding housing, and a card ejection mechanism mounted on one side of the shielding housing, characterized in that, The shielding housing includes a plate portion and a first sidewall formed by bending downward from the outer lateral edge of the plate portion. The first sidewall is torn in the middle to form a tear. The first sidewall is bent inward below the tear to form a clamping spring arm. The side edge of the plate portion is bent downward at the tear to form a push rod limiting member. The ejection mechanism includes a push rod inserted between the first sidewall and the push rod limiting member. The push rod is located above the clamping spring arm and the vertical projection of the push rod and the clamping spring arm at least partially overlaps.
2. The card connector of claim 1, wherein The first sidewall includes at least two connecting walls that bend downwards from the edge of the plate and a side beam that connects the free ends of the two connecting walls as a single unit. The clamping spring arm is formed by bending inwards from the middle of the side beam. The tear is located between the two connecting walls. The push rod limiting member includes a limiting inner wall that bends downwards from the side edge of the plate and a limiting bottom wall that bends outwards towards the side beam from the limiting inner wall. The limiting inner wall is located inside the connecting wall. A push rod insertion space is defined between the limiting inner wall, the limiting bottom wall, and the connecting wall. The push rod is inserted into the push rod insertion space from the front.
3. The card connector of Claim 2, wherein The bottom side of the push rod is supported by the limiting bottom wall, the top of the push rod is limited by the inner wall of the plate, the outer side of the push rod is limited by the connecting wall, and the inner side of the push rod is limited by the limiting inner wall. There are two push rod limiting members, which are respectively located near the two connecting walls. The push rod limiting member located on the front side also includes a pressing spring arm that extends obliquely backward and upward from the limiting bottom wall to abut against the bottom surface of the push rod.
4. The card connector of Claim 3, wherein The side edge of the plate portion at the tear location extends outward to form a pressing plate located above the pressing spring arm, and the pressing plate limits the top of the push rod.
5. The card connector of Claim 4, wherein The card holder includes a metal middle plate and a frame formed around the metal middle plate. The metal middle plate defines a first card-carrying space and a second card-carrying space on its upper and lower sides. The bottom of the frame protrudes outward from the position of the clamping spring arm to form a clamping protrusion. The clamping protrusion has a clamping groove for locking the clamping spring arm. The frame has an avoidance groove above the clamping protrusion to avoid the push rod limiting member.
6. The card connector of Claim 5, wherein The front end of the shielding shell is bent downward to form a second sidewall. The second sidewall includes a vertical inner wall bent downward from the side edge of the plate, a support platform bent outward from the vertical inner wall, and a weld foot bent downward from the outside of the support platform. The vertical inner wall and the limiting inner wall are on the same plane in the front-back direction. The support platform and the limiting bottom wall are on the same horizontal plane. The support platform and the limiting bottom wall together support the bottom side of the push rod. The vertical inner wall and the limiting inner wall together limit the inner side of the push rod.
7. The card connector of Claim 6, wherein The shielding housing also includes a tail wall formed by bending downward from the rear end of the plate portion. A riveting hole is formed through the inner side of the tail wall of the plate portion. The inner surface of the plate portion is covered by the insulating body. A portion of the inner surface of the plate portion at the rear end of the push rod is not covered by the insulating body and forms an exposed area. The push rod mechanism also includes an actuator. The actuator includes a rotating shaft portion rotatably riveted to the riveting hole by a rivet, a locking push portion and a force receiving end extending from both ends of the rotating shaft portion, respectively. There is an included angle between the locking push portion and the force receiving end. A bending portion is also included between the force receiving end and the rotating shaft portion so that the force receiving end extends beyond the thickness of the insulating body and fits against the exposed area of the plate portion.
8. The card connector as claimed in claim 7, characterized in that, The push rod includes a rod body, a pushing end formed at the rear end of the rod body to interfere with and link with the force-bearing end of the actuator, and a pressing end formed at the front end of the rod body. The bottom surface of the rod body includes a plurality of support points for supporting the inner wall of the limiting device and the support platform, and a first limiting protrusion and a second limiting protrusion opened at the position of the pressing spring arm.
9. The card connector of Claim 8, wherein After the push rod is inserted into the push rod insertion space from the front end, in the inserted state, the pressing spring arm abuts against the first limiting protrusion and restricts the push rod from exiting. In the uninserted state, the pressing spring arm abuts against the second limiting protrusion to temporarily maintain the position of the push rod. The height of the first limiting protrusion is greater than the height of the second limiting protrusion.
10. The card connector of Claim 2, wherein The side beam is formed by bending inward from the lower end of the connecting wall and then extending downward.
