Description

A card cover and its card connector

[0001] This application claims priority to Chinese Patent Application No. 202411854167.4, filed on December 16, 2024, entitled "A Card Cover and Card Connector Thereof", the contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to a card cover and its card connector. Background Technology

[0003] For relevant prior art, please refer to Chinese Invention Patent Announcement CN113394581B, which discloses an electronic card connector, including: a terminal module and a metal housing. The metal housing and the terminal module cooperate to define a mating space and form an insertion port at the front end. The mating space is for inserting a module. The terminal module includes an insulating body and a plurality of conductive terminals fixed within the insulating body. The metal housing includes a top plate and two side plates extending downward from both sides of the top plate. At least one of the side plates extends at its lower edge away from the top plate to form a connecting plate. The connecting plate is disposed opposite to the top plate. The connecting plate further extends towards the top plate to form an elastic arm. The elastic arm is used to elastically contact the inserting module in the mating space. A latching lever is provided between the elastic arm and an adjacent side plate. In this card connector structure, because the elastic arm and the latching lever are arranged side by side, the overall width of the card connector is relatively large. When the elastic arm undergoes lateral deformation under force, it is easy to touch the latching lever and rub against it, resulting in poor insertion and removal feel.

[0004] Therefore, it is necessary to design a new card cover and card connector to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this application is to provide a card cover and its card connector, which can achieve a miniaturized design and smooth insertion and removal of the module, improving the insertion and removal feel.

[0022] Along the vertical direction, the operating lever is located above the first curved section.

[0023] Furthermore, it includes: a first stop plate, formed by bending the first side plate from the side away from the top plate in the vertical direction toward the side where the insertion space is located;

[0024] The third stop plate is formed by bending the first side plate from the middle position in the vertical direction toward the side where the insertion space is located;

[0044] The separator is attached to the frame and divides the card-accommodating space into an upper space above the separator and a lower space below the separator in the vertical direction. Each of the upper and lower spaces can accommodate an electronic card.

[0070] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0071] In the description of this application, it should be understood that the terms “comprising” and “having” as used herein, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are expressly listed, but may include other steps or units that are not expressly listed or that are inherent to such process, method, product, or apparatus.

[0072] Furthermore, for the sake of accuracy in the entire description of this application, all directions mentioned in this application shall be referred to Figures 1, 7, 10, and 13. Specifically, the X-axis direction is defined as the insertion and removal direction of the insertion module 200 (as shown in Figures 18 and 19, which is actually the card tray used to carry electronic cards); the Y-axis direction is defined as the up and down direction, with the positive Y-axis direction being up; and the Z-axis direction is defined as the left and right direction.

[0073] Referring to Figures 1 to 6, this application discloses a card connector, which is generally used to assemble onto a mating substrate within electronic devices (such as smartphones, tablets, and smartwatches). The card connector includes a card cover and a terminal assembly 5 that mates with the card cover. The card cover includes a metal housing 1 and a card ejection mechanism 3 assembled onto the metal housing 1. The metal housing 1 is formed by stamping and bending a metal sheet, and includes a top plate 11 and a first side plate 12 and a second side plate 13 extending downwards from both sides of the top plate 11. The top plate 11, the first side plate 12, and the second side plate 13 together form an insertion space 101 and an insertion port 102 at one end.

[0074] The first side plate 12 has a first locking spring 2 formed by stamping and bending. The first locking spring 2 extends into the insertion space 101 from its midpoint along the insertion direction, forming a first curved section 21. Both ends of the first curved section 21 along the insertion direction are integrally connected to the first side plate 12 via first elastic sections 22, and the first locking spring 2 is formed as a fixed beam. The first curved section 21 can elastically deform in the left-right direction, and serves to elastically limit the insertion module (not shown, such as a card tray carrying an electronic card) inserted into the insertion space 101 through the insertion port 102, preventing the insertion module from accidentally dislodging from the insertion space 101. The first locking spring 2 is directly formed on the first side plate 12; preferably, the extension plane of the first elastic section 22 is coplanar with the extension plane of the first side plate 12.

[0075] Furthermore, a second locking spring 4 is formed on the second side plate 13 by stamping and bending. The second locking spring 4 extends into the insertion space 101 from the middle position along the insertion direction to form a second curved section 41. The two ends of the second curved section 41 along the insertion direction are integrally connected to the second side plate 13 through second elastic sections 42, and the second locking spring 4 is also in the shape of a fixed beam. The second curved section 41 can elastically deform in the left-right direction. The second curved section 41 is used to elastically limit the insertion module inserted into the insertion space 101 through the insertion port 102, preventing the insertion module from accidentally coming out of the insertion space 101. The second locking spring 4 is directly formed on the second side plate 13. Preferably, the extension plane of the second elastic section 42 is coplanar with the extension plane of the second side plate 13. In this embodiment, the first locking spring 2 and the second locking spring 4 have the same structure. With the central dividing plane between the extended plane of the first side plate 12 and the extended plane of the second side plate 13 as a mirror surface, the first locking spring 2 and the second locking spring 4 are mirror-symmetrically arranged.

[0076] Referring to Figures 4 to 6, the first side plate 12 is bent towards the insertion space 101 from near its center in the vertical direction to form a first stop piece 20. The top plate 11 is bent towards the insertion space 101 from the side adjacent to the first side plate 12 to form multiple second stop pieces 10. The top plate 11, the first stop pieces 20, the second stop pieces 10, and the first side plate 12 together form the operating rod insertion cavity 301. The ejection mechanism 3 includes an ejection rod 31 and an operating rod 32. The ejection rod 31 is rotatably connected to the end of the metal shell 1 away from the insertion port 102 in the insertion / removal direction. Specifically, the middle position of the ejection rod 31 is rotatably riveted to the lower surface of the corresponding position on the top plate 11 by a rivet. The operating rod 32 is inserted and assembled into the operating rod insertion cavity 301 along the insertion / removal direction. The operating rod 32 can slide within the operating rod insertion cavity 301 along the insertion / removal direction. The end of the operating lever 32 away from the insertion port 102 along the insertion and removal direction is connected to one end of the ejector lever 31 (specifically, it can be designed so that one end of the operating lever 32 abuts against one end of the ejector lever 31).

[0077] In this embodiment, the operating lever 32 is located above the first curved section 21 in the vertical direction. The operating lever 32 includes a main body section 321 extending in the insertion / removal direction. The main body section 321 is attached to the inner surface of the first side plate 12. The operating lever 32 overlaps with the projection portion of the first curved section 21 in the vertical direction. This design reduces the space occupied by the first locking spring 2 and the operating lever 32 in the left-right direction, allowing the operating lever 32 and the first locking spring 2 to form a vertical structure design. This reduces the overall width of the card cover in the left-right direction. More importantly, this vertical structure design avoids the risk of the first locking spring 2 colliding with the operating lever 32 during elastic deformation in the left-right direction due to the insertion of the insertion module. It reduces the possibility of plastic deformation of the first locking spring 2, making the insertion and removal of the insertion module smooth. It also improves the feel of inserting and removing the insertion module and avoids other possible adverse situations caused by collisions and friction between the first locking spring 2 and the operating lever 32.

[0078] Furthermore, referring to Figures 2 and 5, in a preferred embodiment, the top plate 11 forms a downwardly extending, cantilevered stop spring 110 directly above the operating rod insertion cavity 301 along the vertical direction. The stop spring 110 elastically abuts against a stop groove 3210 formed on the upper surface of the main body section 321 of the operating rod 32. The stop spring 110 is used to limit excessive displacement of the operating rod 32 along the insertion and removal direction, preventing the operating rod 32 from accidentally dislodging from the operating rod insertion cavity 301.

[0079] Please refer to Figures 7 to 9, which show the second embodiment of the card cover of this application. The main difference between the card cover in the second embodiment and the first embodiment lies in the position of the operating rod implantation cavity 301'. Specifically, in the second embodiment, the first side plate 12 is bent towards the side of the insertion space 101 along the vertical direction away from the top plate 11 to form a first stop piece 20'. The first stop piece 20' is further bent upward along its free end in the horizontal direction to form a second stop piece 30'. The first side plate 12 is bent towards the side of the insertion space 101 along its middle position in the vertical direction to form a third stop piece 10'. In other modified embodiments, the third stop piece 10' is further bent downward along its free end in the horizontal direction to form the second stop piece 30'. The second stop piece 30' and the first side plate 12 are arranged parallel to each other in the horizontal direction. The first side plate 12, the first stop plate 20', the second stop plate 30', and the third stop plate 10' together form an operating rod insertion cavity 301', and the operating rod 32 is inserted and assembled in the operating rod insertion cavity 301' along the insertion and extraction direction. In the vertical direction, the operating rod 32 is located below the first bent section 21. Further, in the second embodiment, the stop spring 110' is formed by bending the lower edge of the first side plate 12 towards the side where the insertion and extraction space is located and extending upwards at an angle along the insertion and extraction direction. The stop spring 110' elastically abuts against the stop groove 3210' formed on the lower surface of the main body section 321 of the operating rod 32.

[0080] Please refer to Figures 10 to 12, which show the third embodiment of the card cover of this application. The main difference between the card cover in the third embodiment and the first embodiment lies in the position of the operating rod implantation cavity 301''. Specifically, the first side plate 12 is bent towards the side of the insertion space 101 along the vertical direction away from the top plate 11 to form a first stop piece 20''. The top plate 11 is bent towards the side of the insertion space 101 along the side of the first side plate 12 to form a second stop piece 10''. In some variations, the second stop piece 10'' can also be formed by bending the free end of the first stop piece 20'' upwards along the horizontal direction. The first side plate 12, the first stop piece 20'', the second stop piece 10'', and the top plate 11 together form the operating rod implantation cavity 301''. The operating rod 32 in the second embodiment is wider in the vertical direction than in the first and second embodiments. The operating rod 32 is implanted and assembled in the operating rod implantation cavity 301'' along the insertion and extraction direction. Furthermore, the operating lever 32 is formed through the clearance notch 40 in the left-right direction, and the first curved segment 21'' passes through the clearance notch 40 and protrudes into the insertion space 101. In the third embodiment, the first curved segment 21'' is a cantilever beam shape with only one end integrally connected to the first side plate 12. Specifically, the first curved segment 21'' extends obliquely from the first side plate 12 into the insertion space 101 and along the insertion direction. Of course, in the third embodiment, the structure of the first curved segment 21'' can also adopt a structure similar to that shown in the first embodiment (Figures 1 to 6). In addition, in the third embodiment, the structural positions of the stop spring 110'' and the stop groove 3210'' are the same as in the second embodiment.

[0081] Please refer to Figures 13 to 15, which show the fourth embodiment of the card cover of this application. The main difference between the card cover in the fourth embodiment and the second embodiment lies in the different formation positions of the structure defining the operating rod implantation cavity 301'''. Specifically: the first side plate 12 is bent towards the side of the insertion space 101 along the vertical direction away from the top plate 11 to form a first stop piece 10'''. The first stop piece 10''' is further bent upward along the free end in the left-right direction to form a second stop piece 20'''. The second stop piece 20''' is further folded back towards the side of the first side plate 12 along the vertical direction to form a third stop piece 30'''. The first side plate 12, the first stop piece 10''', the second stop piece 20''', and the third stop piece 20''' together form the operating rod implantation cavity 301''', and the operating rod 32 is implanted and assembled in the operating rod implantation cavity 301''' along the insertion and extraction direction. Along the vertical direction, the operating lever 32 is located below the first curved section 21. Furthermore, in the fourth embodiment, the structural arrangement of the stop spring 110''' and the stop groove 3210''' is the same as in the second embodiment.

[0082] Please refer to Figure 16, which shows the fifth embodiment of the card cover of this application. The fifth embodiment is a variation of the fourth embodiment shown in Figures 13 to 15. The main difference is that multiple first stop pieces 10'''', second stop pieces 20'''', and third stop pieces 30'''' are respectively provided, and the width of each one along the insertion / removal direction is narrower than that of the fourth embodiment. A detailed comparison of Figures 16 and 15 can clearly show this.

[0083] Please refer to Figure 17, which shows the sixth embodiment of the card cover of this application. The sixth embodiment is actually a variation of the fifth embodiment shown in Figure 16. The main difference is that the third stop piece 30''''' is formed by bending the first side plate 12 toward the side where the insertion space 101 is located, and the third stop piece 30''''' has a shape that extends along a plane perpendicular to the up and down direction, and also has a shape that extends along a plane perpendicular to the insertion and removal direction.

[0084] By implementing any one of the four embodiments exemplified in this application, the same or similar technical effects can be achieved.

[0085] The card cover of this application also includes a terminal assembly 5 integrally injection molded onto the inner wall of the top plate 11 of the metal housing 1. The terminal assembly 5 includes an insulating body 51 and a plurality of conductive terminals 52 fixed to the insulating body 51. Each conductive terminal 52 includes a terminal fixing section 521 fixed inside the insulating body 51, a terminal docking section 522 extending from the terminal fixing section 521 outside the insulating body 51 for electrical connection with the docking substrate, and a terminal elastic contact section 523 extending further from the terminal fixing section 521 into the insertion space 101 to correspond to the insertion module inserted into the insertion space 101 for signal transmission. Of course, the terminal assembly 5 can also be independently arranged in a block form (see Figure 2) to cooperate with the card cover. Alternatively, the terminal assembly 5 can be integrated on the inner wall of the top plate 11 of the metal housing 1, and used in conjunction with one or more independently arranged block-shaped terminal assemblies 5. Figures 1 to 6 of this application show the terminal assembly 5 integrated on the inner wall of the top plate 11 of the metal housing 1, and used in conjunction with two independently arranged block-shaped terminal assemblies 5.

[0086] Please refer to Figures 18 and 19, which illustrate an insertion module 6 used in conjunction with the card cover or card connector of this application. This insertion module 6 is essentially a card tray used to hold an electronic card (not shown) before inserting it into the insertion space 101. The card tray includes a frame member 61 and a partition member 62. The frame member 61 includes two side frame members 611 spaced apart, a front frame member 612 connecting one end of the two side frame members 611, and a rear frame member 613 connecting the other ends of the two side frame members 611. The two side frame members 611, the front frame member 612, and the rear frame member 613 together form a card receiving space 610. The partition member 62 is attached to the frame member 61 and divides the card receiving space 610 into an upper space above the partition member 62 and a lower space below the partition member 62, each capable of accommodating an electronic card. A notch 601 is formed at the connection between the front frame 612 and one of the side frames 611 of the card tray. The notch 601 is located above or below the plane of the separator 62 (corresponding to a chamfered position of the electronic card, such as a Nano SIM card). Along the vertical direction, the portion of the card tray corresponding to the notch 601 forms an implantation portion 602. When the card tray is fully inserted into the insertion space 101 (until it can no longer be inserted), the notch 601 is used to make way for the card ejection lever 31 (corresponding to the position of the card ejection lever 31 near the operating lever 32). Specifically, the position of the card ejection lever 31 near the operating lever 32 is partially accommodated within the notch 601, and the implantation portion 602 is stacked along the vertical direction with the portion of the card ejection lever 31 near the operating lever 32. This facilitates miniaturization design.
