[0037] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] In the description of this application, it should be understood that the terms "include" and "have" and any variations thereof used herein are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0039] In addition, for the accuracy of the description of the entire application, all directions involved in the entire application should be referred to as Figure 1 , Figure 7 , Fig.10 , Fig.13 For reference, the X-axis direction is specifically defined as the insertion module 200 ( Fig.18 , Fig.19 As shown, it is actually the insertion and removal direction of the card tray for carrying the electronic card; the direction of the Y axis is defined as the up and down direction, where the positive direction of the Y axis is upward; the direction of the Z axis is defined as the left and right direction.

[0040] Please refer to Figures 1 to 6As shown, a card connector disclosed in the present application is generally used to be assembled on a docking substrate in an electronic device (such as a smart phone, a tablet computer, a phone watch, etc.). The card connector of the present application includes a card cover and a terminal assembly 5 used in conjunction with the card cover. Among them, the card cover includes a metal shell 1 and a card ejection mechanism 3 assembled on the metal shell 1. The metal shell 1 is formed by stamping and bending a metal plate, including a top plate 11 and a first side plate 12 and a second side plate 13 formed by extending downward from both sides of the top plate 11. The top plate 11, the first side plate 12 and the second side plate 13 are jointly arranged to form a plug-in space 101 and form an insertion port 102 at one end.

[0041] Among them, a first locking card spring 2 is formed on the first side plate 12 by stamping and bending. The first locking card spring 2 is bent and extended into the plug-in space 101 at the middle position along the plug-in direction to form a first curved section 21. The two ends of the first curved section 21 along the plug-in direction are respectively connected to the first side plate 12 through the first elastic section 22, and the first locking card spring 2 is in the shape of a fixed beam as a whole. The first curved section 21 can be elastically deformed in the left and right directions. The first curved section 21 is used to play an elastic limiting role for the insertion module (not shown, such as a card tray carrying an electronic card) inserted into the plug-in space 101 through the insertion port 102, so as to prevent the insertion module from accidentally falling out of the plug-in space 101. The first locking card 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.

[0042] Furthermore, a second locking spring piece 4 is formed on the second side panel 13 by stamping and bending. The second locking spring piece 4 is bent and extended into the plug-in space 101 at the middle position along the plug-in direction to form a second curved section 41. The two ends of the second curved section 41 along the plug-in direction are integrally connected to the second side panel 13 through the second elastic section 42, and the second locking spring piece 4 is also fixed beam-shaped as a whole. The second curved section 41 can be elastically deformed along the left and right directions, and the second curved section 41 is used to elastically limit the insertion module inserted into the plug-in space 101 through the insertion port 102, so as to prevent the insertion module from accidentally falling out of the plug-in space 101. The second locking spring piece 4 is directly formed on the second side panel 13. Preferably, the extension plane of the second elastic section 42 is coplanar with the extension plane of the second side panel 13. In this embodiment, the first locking card spring piece 2 and the second locking card spring piece 4 have the same structure, and the central dividing plane between the extension plane of the first side plate 12 and the extension plane of the second side plate 13 is used as a mirror plane, and the first locking card spring piece 2 and the second locking card spring piece 4 are arranged in mirror symmetry.

[0043] Please refer to Figures 4 to 6As shown, the first side plate 12 is bent toward the side where the plug-in space 101 is located near the middle position in the up-down direction to form a first stopper 20. The top plate 11 is bent toward the side where the plug-in space 101 is located near the first side plate 12 to form a plurality of second stopper plates 10. The top plate 11, the first stopper plate 20, the second stopper plate 10 and the first side plate 12 are jointly arranged to form an operating rod implantation cavity 301. The card ejection mechanism 3 includes a card ejection rod 31 and an operating rod 32. The card ejection rod 31 is rotatably coupled to an end position of the metal shell 1 away from the insertion port 102 in the plug-in and pull-out direction. Specifically, the middle position of the card ejection rod 31 is rotatably riveted to the lower surface of the corresponding position of the top plate 11 by rivets. The operating rod 32 is implanted and assembled in the operating rod implantation cavity 301 along the plug-in and pull-out direction. The operating rod 32 can slide in the operating rod implantation cavity 301 along the plug-in and pull-out direction. One end of the operating rod 32 away from the insertion port 102 along the insertion and extraction direction is linked to one end of the card ejection rod 31 (specifically, it can be designed that one end of the operating rod 32 abuts against one end of the card ejection rod 31 ).

[0044] In this embodiment, the operating rod 32 is located above the first curved section 21 in the up-down direction. The operating rod 32 includes a main section 321 extending in the plug-in and pull-out direction. The main section 321 is attached to the inner surface of the first side plate 12. The operating rod 32 partially overlaps with the projection of the first curved section 21 in the up-down direction. With such a design, the space occupied by the first locking card spring 2 and the operating rod 32 in the left-right direction can be reduced, so that the operating rod 32 and the first locking card spring 2 form a vertical structural design. The width of the card cover as a whole in the left-right direction is reduced. More importantly, this vertical structural design can avoid the risk of the first locking card spring 2 colliding with the operating rod 32 when it is elastically deformed in the left-right direction due to the insertion push of the insertion module, reduce the possibility of plastic deformation of the first locking card spring 2, make the insertion module plug-in and pull-out smooth, and improve the feel of the insertion and pull-out of the insertion module, and avoid other possible adverse conditions caused by collision and friction between the first locking card spring 2 and the operating rod 32.

[0045] For further information, please refer to Figure 2 and Figure 5 As shown, in a preferred embodiment, the top plate 11 is formed with a cantilevered stop spring piece 110 extending downwardly and obliquely just above the operating rod implantation cavity 301 in the up-down direction, and the stop spring piece 110 elastically contacts the stop groove 3210 formed on the upper surface of the main body section 321 of the operating rod 32. The stop spring piece 110 is used to limit the excessive displacement of the operating rod 32 in the insertion and extraction direction, and prevent the operating rod 32 from accidentally falling out of the operating rod implantation cavity 301.

[0046] Please refer to Figures 7 to 9As shown, it is the second embodiment of the card cover of the present application. The main difference between the card cover in the second embodiment and the first embodiment is that the position of the operating rod implantation cavity 301' is different. Specifically: In the second implementation example, the first side plate 12 is bent from a position away from the side where the top plate 11 is located in the up-down direction to the side where the plug-in space 101 is located to form a first shifting piece 20'. The free end of the first shifting piece 20' along the left-right direction is further bent upward to form a second shifting piece 30'. The first side plate 12 is bent from the middle position in the up-down direction to the side where the plug-in space 101 is located to form a third shifting piece 10'. In other modified embodiments, the free end of the third shifting piece 10' along the left-right direction is further bent downward to form the second shifting piece 30'. The second shifting piece 30' is arranged opposite to the first side plate 12 in the left-right direction and in parallel with each other. The first side plate 12, the first shifting plate 20', the second shifting plate 30' and the third shifting plate 10' are jointly arranged to form an operating rod implantation cavity 301', and the operating rod 32 is implanted and assembled in the operating rod implantation cavity 301' along the plug-in and pull-out direction. In the up-down direction, the operating rod 32 is located below the first curved section 21. Furthermore, in the second embodiment, the stop spring piece 110' is formed by bending the lower edge of the first side plate 12 toward the side where the plug-in and pull-out space is located and extending obliquely upward along the plug-in and pull-out direction, and the stop spring piece 110' corresponds to elastic resistance in the stop groove 3210' formed on the lower surface of the main section 321 of the operating rod 32.

[0047] Please refer to Figures 10 to 12As shown, it is the third embodiment of the card cover of the present application. The main difference between the card cover in the third embodiment and the first embodiment is that the position of the operating rod implantation cavity 301'' is different. Specifically: the first side plate 12 is bent toward the side where the plug-in space 101 is located, away from the side where the top plate 11 is located, in the up-down direction to form a first stopper 20''. The side of the top plate 11 adjacent to the first side plate 12 is bent toward the side where the plug-in space 101 is located to form a second stopper 10''. In some variations, the second stopper 10'' can also be formed by bending and extending the free end of the first stopper 20'' in the left-right direction upward. The first side plate 12, the first stopper 20'', the second stopper 10'' and the top plate 11 are jointly arranged to form an operating rod implantation cavity 301''. The width of the operating rod 32 in the second embodiment along the up-down direction is wider than that of the first and second embodiments. The operating rod 32 is implanted and assembled in the operating rod implantation cavity 301'' along the plug-in direction. Furthermore, the operating rod 32 is formed with a clearance notch 40 in the left-right direction, and the first curved section 21'' passes through the clearance notch 40 and protrudes into the insertion space 101. In the third embodiment, the first curved section 21'' is a cantilever beam with only one end connected to the first side plate 12 as a whole. Specifically, the first curved section 21'' is formed by the first side plate 12 extending obliquely toward the insertion space 101 and along the insertion direction. Of course, in the third embodiment, the structure of the first curved section 21'' can also be similar to that of the first embodiment ( Figures 1 to 6 In addition, in the third embodiment, the structural arrangement positions of the stop spring piece 110'' and the stop groove 3210'' are the same as those of the second embodiment.

[0048] Please refer to Figures 13 to 15As shown, it is the fourth embodiment of the card cover of the present application. The main difference between the card cover in the fourth embodiment and the second embodiment is that the formation position of the structure defining the operating rod implantation cavity 301''' is different. Specifically: the first side plate 12 is bent toward the side where the plug-in space 101 is located, away from the side where the top plate 11 is located, in the up-down direction to form a first stopper 10'''. The free end of the first stopper 10''' in the left-right direction is further bent upward to form a second stopper 20'''. The free end of the second stopper 20''' in the up-down direction is further folded back toward the side where the first side plate 12 is located to form a third stopper 30'''. The first side plate 12, the first stopper 10''', the second stopper 20''' and the third stopper 20''' are jointly surrounded to 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 plug-in direction. In the up-down direction, the operating rod 32 is located below the first curved section 21. In addition, in the fourth embodiment, the structural arrangement positions of the stop spring piece 110''' and the stop groove 3210''' are the same as those of the second embodiment.

[0049] Please refer to Fig.16 As shown, it is the fifth embodiment of the card cover of the present application. The fifth embodiment is Figures 13 to 15 The main difference of the modified example of the fourth embodiment shown in the figure is that: a plurality of first shifting pieces 10'''', second shifting pieces 20'''' and third shifting pieces 30'''' are provided, and the width of each piece along the plugging and unplugging direction is narrower than that of the fourth embodiment. Fig.16 and Fig.15 Can see clearly.

[0050] Please refer to Fig.17 As shown, it is the sixth embodiment of the card cover of the present application. The sixth embodiment is actually Fig.16 The modification of the fifth embodiment shown in the figure mainly differs in that the third shifting piece 30''''' is formed by bending the first side plate 12 toward the side where the plug-in space 101 is located, and the third shifting piece 30''''' is formed in a shape extending along a plane perpendicular to the up-down direction, and is also formed in a shape extending along a plane perpendicular to the plug-in direction.

[0051] By implementing any one of the above four embodiments listed in this application, the above same or similar technical effects can be achieved.

[0052] The card cover of the present application also includes a terminal assembly 5 integrated on the inner wall surface of the top plate 11 of the metal shell 1 by integral injection molding, the terminal assembly 5 includes an insulating body 51 and a plurality of conductive terminals 52 fixed to the insulating body 51, each of the conductive terminals 52 includes a terminal fixing section 521 fixed in the insulating body 51, a terminal docking section 522 extending from the insulating body 51 by the terminal fixing section 521 for electrical connection with a docking substrate, and a terminal elastic contact section 523 extending from the terminal fixing section 521 further into the plug-in space 101 to form a corresponding plug-in module inserted into the plug-in space 101 to realize signal transmission. Of course, the terminal assembly 5 can also be in the form of an independently set tofu block (refer to FIG. Figure 2 Of course, the terminal assembly 5 can also be integrated on the inner wall surface of the top plate 11 of the metal housing 1, and used in conjunction with one or more independently set tofu block-shaped terminal assemblies 5. Figures 1 to 6 What is shown is the integrated terminal assembly 5 on the inner wall surface of the top plate 11 of the metal shell 1, and two independently set terminal assemblies 5 in the form of tofu blocks.

[0053] Please refer to Fig.18 and Fig.19As shown, an insertion module 6 used in conjunction with the card cover or card connector of the present application is actually a card tray, which is used to carry an electronic card (not shown) and then be inserted into the plug-in 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 arranged relatively 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 are jointly arranged to form a card accommodating space 610. The partition member 62 is combined with the frame member 61 and divides the card accommodating space 610 into an upper space located above the partition member 62 and a lower space located below the partition member 62 in the up-down direction, and the upper space and the lower space can each accommodate an electronic card. A notch 601 is formed at the connection position between the front frame 612 of the card tray and one of the side frames 611. The notch 601 is located above or below the plane where the partition 62 is located (corresponding to a chamfered position of an electronic card, such as a Nano SIM card); along the up and down 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 (inserted until it cannot be inserted any further), the notch 601 is used to make way for the card ejection rod 31 (corresponding to the position of the card ejection rod 31 near one end of the operating rod 32), which is specifically manifested as: the position of the card ejection rod 31 near one end of the operating rod 32 is partially accommodated in the notch 601, and the implantation portion 602 is stacked with the portion of the card ejection rod 31 near one end of the operating rod 32 along the up and down direction.
