Description

Technical Field

[0001] This invention relates to the field of electrical connectors, and more particularly to a card cover assembly and a card connector. Background Technology

[0002] Card connectors are used to load SIM cards, memory cards, etc., and are widely used in mobile electronic devices. Initially, card connectors directly inserted SIM cards and TF cards. However, with the miniaturization of electronic cards, card trays were developed to load electronic cards, which were then inserted into the card connector. The evolution of multi-card devices has led to the emergence of multi-in-one electronic cards. Currently, the most common type is the stacked card connector, which loads two electronic cards stacked vertically. For example, the People's Republic of China Patent No. 201710893442.7 discloses a card connector that includes an insulating body, conductive terminals fixed within the insulating body, and a shielding shell covering the insulating body. The insulating body and the shielding shell together form a receiving cavity for inserting an electronic card in the insertion / removal direction. The shielding shell has a top wall and a pair of side walls that bend downwards from both sides of the top wall. The side walls are provided with solder feet for mounting to a circuit board. The conductive terminals and the insulating body are held together on the top wall of the shielding shell. The electronic card connector also includes a card ejection mechanism mounted on the shielding shell and an elastic retaining part bent from the top wall and located inside the card ejection mechanism. The elastic retaining part is used to stabilize the card tray for loading the electronic card. Summary of the Invention

[0003] Therefore, it is necessary to provide a card cover assembly and card connector that can effectively reduce the lateral width of the product.

[0004] To address the aforementioned technical problems, this application provides a card cover assembly, comprising a shielding shell having a plate portion and a first sidewall formed by bending from both sides of the plate portion laterally, a terminal group, an insulating body integrally formed with the terminal group on the inner surface of the plate portion, and a card ejection mechanism. The card ejection mechanism includes an actuator rotatably fixed to the rear end of the plate portion and a push rod installed on the inner side of the sidewall. The first sidewall includes at least two connecting walls formed by bending downward from the edge of the plate portion, a tear between the two connecting walls, a side beam connecting the free ends of the two connecting walls integrally, and a clamping spring arm formed by bending inward from the middle of the side beam. The plate portion is bent at the tear to form a push rod limiting member located above the clamping spring arm. The push rod is inserted between the push rod limiting member and the connecting wall and located above the clamping spring arm.

[0005] Preferably, the push rod limiting member includes a limiting inner wall formed by bending downward from the side edge of the plate body and a limiting bottom wall formed by bending outward from the limiting inner wall toward the side beam. 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.

[0006] Preferably, 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 surface of the plate body, the outer side of the push rod is limited by the connecting wall, the inner side of the push rod is limited by the limiting inner wall, and the rear end of the push rod interferes with the actuator.

[0007] Preferably, there are two push rod limiting members, each located near one of the two connecting walls. The push rod limiting member located on the front side further includes a pressing spring arm extending obliquely backward and upward from the limiting bottom wall to abut against the bottom surface of the push rod.

[0008] Preferably, 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.

[0009] Preferably, 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 portion, 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-rear 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.

[0010] Preferably, the shielding housing further 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 actuator includes a rotating shaft portion rotatably riveted to the riveting hole by a rivet, a push portion and a force-receiving end extending from both ends of the rotating shaft portion, respectively. There is an angle between the 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.

[0011] Preferably, 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 has 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.

[0012] Preferably, after the push rod is inserted into the push rod insertion space from the front end, in the inserted state, the pressing spring abuts against the first limiting protrusion and restricts the push rod from retracting; in the uninserted state, the pressing spring 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. The side beam is formed by bending inward from the lower end of the connecting wall and then extending downward.

[0013] To address the aforementioned technical problems, this application also provides a card connector, including the aforementioned card cover assembly, a printed circuit board with a terminal module mounted on it, and a card tray. The terminal module and the shielding housing define a card insertion space, and the card tray is housed within the card insertion space. The card tray includes a metal middle plate and a frame formed around the metal middle plate. The upper and lower sides of the metal middle plate define a first card-carrying space and a second card-carrying space. 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.

[0014] Preferably, the metal middle plate includes a support plate and a bent insert formed by bending downward from the periphery of the support plate. The bent insert has a plurality of flow holes at the junction with the support plate, and the bent insert extends into the clamped protrusion.

[0015] The card cover assembly and card connector of this application change the defect in the prior art where the clamping spring arm and the push rod are arranged sequentially in the lateral direction and occupy the lateral space of the card cover assembly by placing the push rod of the card ejection mechanism above the clamping spring arm on the side wall. This makes the push rod no longer occupy the width space of the card cover assembly alone, thus reducing the width of the card cover assembly and card connector. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings.

[0029] Please see Figures 1 to 4 As shown, the card cover assembly and card connector of this application are... Figure 1 The X direction is the front end in the vertical direction (i.e., the card insertion direction), the Y direction is the left side in the horizontal direction, and the Z direction is the top in the vertical direction.

[0030] This application's card connector includes a printed circuit board 10, a card cover assembly 30 mounted on the printed circuit board 10, and a card tray 20 movable between the card cover assembly 30 and the printed circuit board 10. A card insertion space 40 is formed between the card cover assembly 30 and the printed circuit board 10, and the card tray 20 is inserted and removed within the card insertion space 40. A terminal module (not shown) is also mounted on the printed circuit board 10, the terminal module being used for contact with an electronic card.

[0031] The card holder 20 includes a metal middle plate 21 and a frame 22 formed outside the metal middle plate 21. The metal middle plate 21 includes a flat support plate 211 and a bent insert 212 formed by bending downward from the outer periphery of the support plate 211. The bent insert 212 and the support plate 211 are provided with flow holes 213 at the bending point to make the frame 22 and the metal middle plate 21 more firmly bonded during forming.

[0032] The frame 22 includes a side frame 221 formed around the periphery of the metal middle plate 21, a middle portion 224 extending forward from the side frame 221, and a head 225 formed at the front end of the middle portion 224. The side frame 221 includes clamping protrusions 222 protruding outward from the bottom of both sides of the side frame 221, clearance grooves 227 formed above the clamping protrusions 222, and clamping grooves 223 formed on the clamping protrusions 222. An annular sealing groove 226 is formed on the outer periphery of the middle portion 224 for fitting a sealing ring.

[0033] The metal middle plate 21 has a first card-carrying space 201 and a second card-carrying space 202 formed on its upper and lower sides, respectively. The outer periphery of the first card-carrying space 201 is the side of the side frame 221 corresponding to the clearance groove 227, and the outer periphery of the second card-carrying space 202 is the side of the side frame 221 corresponding to the clamped protrusion 222. A card-holding member 23 is installed on the middle part 224 near the first card-carrying space 201 or the second card-carrying space 202. The card-holding member 23 is elastic. When an electronic card is installed in the first card-carrying space 201 or the second card-carrying space 202, the card-holding member 23 applies pressure to the electronic card so that the electronic card will not fall out when inverted. The end of the bent insert 212 extends into the clamped protrusion 222, thereby increasing the length of the bent insert 212 to increase its firmness.

[0034] Please continue reading Figures 5 to 9 As shown, the card cover assembly 30 of this application includes a shielding housing 31, a terminal group 33, an insulating body 32 integrally formed with the terminal group 33 on the shielding housing 31, and a card ejection mechanism installed on the shielding housing 31.

[0035] The shielding housing 31 includes a plate portion 311, side walls formed by bending downward from both sides of the plate portion 311, a tail wall 315 formed by bending downward from the rear end of the plate portion 311, a tear opening S formed by tearing and bending from the inner side of the side wall of the plate portion 311, and a push rod limiting member 314 provided in the tear opening S.

[0036] A riveting hole 3111 is provided at the rear end of the plate portion 311 near the tail wall 315. A pressing piece 3113 is formed by extending outward from the lateral side edge of the plate portion 311 and located above the tear S. The side wall includes a first side wall 312 and a second side wall 313 formed in front of the first side wall 312. The first side wall 312 includes a connecting wall 3121 formed by bending downward from the lateral side edge of the plate portion 311 on both sides before and after the tear S, a side beam 3122 that extends downward from the connecting wall 3121 and connects the two connecting walls 3121 together, a clamping spring arm 3123 formed by bending from the middle of the side beam 3122 toward the insertion space 40, and a guarding part 3124 formed by bending inward from the bottom of the side beam 3122. The second sidewall 313 includes a vertical inner wall 3131 formed by bending downward from the plate portion 311, a support platform 3132 formed by bending outward from the vertical inner wall 3131, and a welding foot 3133 formed by bending downward from the outside of the support platform 3132.

[0037] The push rod limiting member 314 includes a limiting inner wall 3141 formed by bending downward from the plate portion 311 at both ends of the pressing plate 3113, and a limiting bottom wall 3142 formed by bending outward from the bottom of the limiting inner wall 3141. The rear end of the limiting bottom wall 3142 located on the front side extends obliquely upward and backward to form a pressing spring arm 3143, which is located below the pressing plate 3113. In other embodiments, the pressing spring arm 3143 may also extend obliquely upward and forward from the limiting bottom wall 3142 located on the rear side.

[0038] Viewed from the front and rear, the vertical inner wall 3131 of the second side wall 313 and the limiting inner wall 3141 of the push rod limiting member 314 are on the same plane, and the limiting bottom wall 3142 and the supporting platform 3132 are on the same plane. The vertical inner wall 3131 and the limiting inner wall 3141 are located inside the connecting wall 3121, and a push rod insertion space is defined between them. The clamping spring arm 3123 is located below the push rod insertion space.

[0039] In one embodiment, the side beam 3122 is formed by bending slightly inward from the connecting wall 3121 and then extending downward. Alternatively, the side beam 3122 may be formed by extending vertically downward from the connecting wall 3121.

[0040] Key references Figure 6As shown, the card ejection mechanism includes an actuator 34 riveted to the riveting hole 3111 of the shielding housing 31 and a push rod 37 installed in the push rod insertion space in the card insertion direction. The actuator 34 includes a pivot portion 342, a push portion 341 extending from one end of the pivot portion 342 to the rear side of the card insertion space 40, and a force-receiving end 343 extending from the other end of the pivot portion 342 to one side of the push rod 37. The inner side of the riveting hole 3111 on the shielding housing 31 is covered by the insulating body 32. A shaft hole (not labeled) is formed through the pivot portion 342 of the actuator 34. The actuator 34 is riveted to the riveting hole 3111 by a rivet 36 through the shaft hole, and the push portion 341 and the pivot portion 342 are attached to the inner side of the insulating body 32. The inner surface of the plate portion 311 of the shielding housing 31 does not cover the insulating body 32 at the rear end of the push rod 37 to form an exposed area 3112. A bending portion 344 is also formed between the force-receiving end 343 and the rotating shaft portion 342, so that the force-receiving end 343 extends upward beyond the thickness of the insulating body 32 relative to the rotating shaft portion 342 or the locking portion 341 and fits into the exposed area 3112. The push rod insertion space where the push rod 37 is located is above the clamping spring arm 3123, that is, close to the inner surface of the plate portion 311, so that the push rod 37 can be directly facing the force-receiving end 343 in the exposed area 3112. The locking portion 341 and the force-receiving end 343 form an obtuse angle around the rotating shaft portion 342. Pushing the force-receiving end 343 allows the actuator 34 to rotate around the rivet 36, thereby causing the locking portion 341 to move forward and push the clip 20.

[0041] The push rod 37 includes a rod body 371, a pushing end 373 formed at the rear end of the rod body 371, and a pressing end 372 formed at the front end of the rod body 371. The bottom surface of the rod body 371 has at least two support points 374 with lower horizontal positions on the front and rear sides, and the middle part of the bottom surface of the rod body 371 has a first limiting protrusion 375, and a second limiting protrusion 376 is provided on the front side of the first limiting protrusion 375.

[0042] Please refer to this carefully. Figure 8 , Figure 9As shown, the push rod 37 is inserted into the push rod insertion space from the front end of the cover assembly 30. The top surface of the rod body 371 is confined below the inner surface of the pressing sheet 3113 and the plate body 311. The bottom surface of the rod body 371 is supported on the support platform 3132 of the second side wall 313 and the limiting bottom wall 3142 of the push rod limiting member 314. The inner side of the rod body 371 is confined outside the vertical inner wall 3131 of the second side wall 313 and the limiting inner wall 3141 of the push rod limiting member 314. The outer side of the rod body 371 is confined inside the connecting wall 3121 of the first side wall 312. Furthermore, the push rod 37 and the clamping spring arm 3123 are offset in the vertical direction so that the push rod 37 and the clamping spring arm 3123 occupy the same lateral space of the cover assembly 30, thereby reducing the lateral width of the cover assembly 30.

[0043] When the card tray 20 containing the electronic card is inserted into the card insertion space 40, the card pusher 341 is pushed to the rear end and remains in a straight position, and the push rod 37 is pushed outward by the force-receiving end 343. When the card tray 20 is fully inserted, the pressing spring arm 3143 of the push rod limiting member 314 abuts against the first limiting protrusion 375 so that the push rod 37 can no longer slide outward. At this time, the clamping spring arm 3123 is clamped inward in the clamping groove 223 of the card tray 20 to keep the card tray 20 stable. At the same time, the clearance groove 227 on the upper side of the clamped protrusion 222 of the card tray 20 is used to avoid the vertical inner wall 3131 of the second side wall 313 and the limiting inner wall 3141 of the push rod limiting member 314. When the pressing end 372 of the push rod 37 is pressed backward, the pushing end 373 pushes the force-receiving end 343 of the actuator 34 backward and rotates around the pivot 342. When the push rod is fully pushed in, the pressing spring arm 3143 moves forward past the second limiting protrusion 376 on the bottom surface of the rod body 37, temporarily holding the push rod in its current position. The height of the second limiting protrusion 376 is less than that of the first limiting protrusion 375, allowing the pressing spring arm 3143 to easily move forward or backward past the second limiting protrusion 376.

[0044] The cover assembly 30 also includes a detection terminal 35, which includes a moving terminal and a stationary terminal (not labeled) integrally formed within the insulating body 32. The function of the detection terminal is prior art and will not be described further here.

[0045] The card cover assembly and card connector of this application change the defect in the prior art where the clamping spring arm 3123 and the push rod 37 are arranged sequentially in the lateral direction and occupy the lateral space of the card cover assembly by placing the push rod 37 of the card ejection mechanism above the clamping spring arm 3123 on the side wall. This makes the push rod 37 no longer occupy the width space of the card cover assembly 30 alone, and reduces the width of the card cover assembly and card connector.

[0046] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
