Abstract
Description
Technical Field
[0001] The present application relates to a card connector assembly and an electronic device. Background Art
[0002] For related prior art, please refer to the Chinese invention patent announcement CN110391520B. This patent discloses an electronic card connector, which includes a terminal module and a shielding housing that cooperates with the terminal module. The terminal module includes an insulating body and a plurality of conductive terminals fixed to the insulating body. The insulating body and the shielding housing jointly define an insertion space for inserting a card tray and form an insertion port. The shielding housing is correspondingly fixed to a circuit board. The shielding housing includes a flat top plate. The front end of the shielding housing at a position away from the circuit board is bent to form a stop portion. The stop portion is located on both sides of the shielding housing, and the stop portion is used to prevent the card tray from being inserted reversely.
[0003] However, due to the design requirements of thin, light, small and miniaturized in the existing technology, in the actual product, the material thickness of the shielding housing is very thin. Therefore, when the stop portion plays the anti-reverse insertion function (that is, when the card tray is inserted reversely), it is often deformed by the relatively large pushing force of the card tray. One of the important reasons is that the stop portion is designed at both sides of the front edge of the top plate. When the stop portion is subjected to an inclined pressing force, the pressing force will be transmitted to the top plate, which easily causes the top plate to be deformed and damaged under force, and further causes the entire insertion frame opening formed by the shielding housing to be deformed and damaged.
[0004] Therefore, it is necessary to design a new card connector to improve the above problems. Utility Model Content

[0044] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0045] For the accurate description of the full text of the present application, all directions involved shall be uniformly based on Figure 1 as a reference, in which the direction where the X-axis is located is defined as the left-right direction; the direction where the Y-axis is located is defined as the up-down direction, where the positive direction of the Y-axis is up; the direction where the Z-axis is located is defined as the front-back direction, where the positive direction of the Z-axis is back.
[0046] Please refer to Figures 1 to 8 shown, a card connector assembly disclosed in the present application includes a metal housing 1, a card ejection mechanism (not labeled) movably assembled on the metal housing, a switch assembly 4, and a terminal assembly 300. Further, the card connector assembly may further include a card holder 6 and a docking circuit board 200 (the docking circuit board 200 may also be an internal substrate of an electronic device) used in cooperation. The card connector assembly can be used to be assembled inside an electronic device, such as a smart phone, a tablet computer, a smart watch, and so on.
[0047] Please refer to Figures 1 to 8As shown, the metal housing 1 includes an inner housing member 101 and an outer housing member 102 covering the periphery of the inner housing member 101. Among them, the inner housing member 101 is formed with an inner top plate 1011 and elastic locking arms 1012 formed by bending downward from the left and right sides of the inner top plate 1011 respectively. Along the front-rear direction, only the two ends of the elastic locking arm 1012 are integrally connected to the inner top plate 1011, and the elastic locking arm 1012 is in the shape of a fixed beam with both ends fixed. The middle position of the elastic locking arm 1012 along the front-rear direction can elastically deform along the left-right direction.
[0048] Among them, the outer housing member 102 is formed with an outer top plate 1021 and outer side plates 1022 formed by further bending downward from the left and right sides of the outer top plate 1021. Further, one side of the outer housing member 102 along the left-right direction also extends and bends to form a limiting plate 1023 located outside the outer side plate 1022. A spacing gap (not labeled) is formed between the limiting plate 1023 and the adjacent outer side plate 1022, and the spacing gap extends along the front-rear direction. In the embodiment of the present application, the inner top plate 1011 and the outer top plate 1021 are stacked along the up-down direction to jointly form a top plate member (not labeled). The elastic locking arms 1012 and the outer side plates 1022 located on the same side along the left-right direction jointly form a side plate member 12. The rear edge of the outer top plate 1021 also bends downward and extends to form an end plate member 13. The top plate member, the side plate member 12, and the end plate member 13 jointly enclose an insertion space 10 and form an insertion port 101 at the front end for the card holder 6 to be inserted.
[0049] During use, the card holder 6 carrying the electronic card 60 is inserted into the insertion space 10 through the insertion port 101. When the card holder 6 is completely inserted into the insertion space 10 and in place, the elastic locking arms 1012 are correspondingly snap-fixed with the snap notches 63 on both sides of the card holder 6, and finally the electrical connection between the electronic card 60 and the terminal assembly 300 is realized. In the embodiment of the present application, the terminal assembly 300 includes an insulating body 31 and a plurality of signal terminals 32 fixed in the insulating body 31. The terminal assembly 300 is welded and fixed to the surface of the docking circuit board 200 through the welding pins 321 of the signal terminals 32. The metal housing 1 correspondingly covers the periphery of the terminal assembly 300, and the electronic card 60 realizes electrical connection with the docking circuit board 200 through the signal terminals 32.
[0050] The card ejection mechanism includes an operating lever 21 and a card ejection lever 22. The operating lever 21 is movably installed in the spacing gap formed between the limiting plate 1023 and the outer plate 1022, and can slide in the spacing gap in the front-back direction. The card ejection lever 22 is rotatably coupled to the rear end position of the inner top plate 1011 of the inner housing member 101, and a relief notch is formed at the corresponding position of the outer top plate 1021 of the outer housing member 102. The rear end position of the card ejection lever 22 is linked to one end of the operating lever 21 in the left-right direction. In the embodiment of the present application, specifically, the card ejection lever 22 and the inner top plate 1011 are rotatably coupled by riveting with a rivet.
[0051] In the embodiment of the present application, the metal housing 1 is designed as a two-piece structure composed of an inner housing member 101 and an outer housing member 102. The main purpose is to enable the elastic latch arm 1012, the limiting plate 1023, and the outer plate 1022 to be selectively formed on different housing components (the inner housing member 101 or the outer housing member 102), which can improve the structural strength of a single inner housing member 101 and outer housing member 102 and provide a greater selection space for arranging the elastic latch arm 1012, the limiting plate 1023, and the outer plate 1022. Of course, in other embodiments, the metal housing 1 can also be designed as a one-piece structure, and only the formation positions of the elastic latch arm 1012, the limiting plate 1023, and the outer plate 1022 need to be appropriately adjusted.
[0052] Further, the switch assembly 4 is coupled to the rear end position of the outer top plate 1021 of the outer housing member 102. Specifically, the switch assembly 4 includes an insulating block 41 and an elastic switch terminal 42 fixedly integrated with the insulating block 41. A plurality of fixing pieces (not shown) are formed by stamping and bending at the rear end position of the outer top plate 1021 of the outer housing member 102, and the outer top plate 1021 and the insulating block 41 are fixed by inserting the fixing pieces correspondingly into the insulating block 41. Further, a contact piece 43 is formed by bending and extending the outer top plate 1021, and the elastic switch terminal 42 is elastically in contact with the contact piece 43 to achieve the switch function.
[0053] Please refer to Figures 1 to 7As shown, a welding portion 121 is integrally formed by extending the lower edge of the outer side plate 1022 located at the insertion port 101 in the left - right direction towards the insertion space 10. The welding portion 121 and the outer top plate 1021 are disposed opposite to each other at an interval in the up - down direction. Further included is an anti - reverse - insertion portion 5, which is integrally connected to the front edge of the side plate member 12 and the front edge of the welding portion 121. The upper edge of the anti - reverse - insertion portion 5 and the lower surface of the top plate member are disposed opposite to each other at an interval in the up - down direction. The welding portion 121 is used for welding and fixing to the docking circuit board 200. Of course, in other embodiments, the outer side plate 1022 can also be formed by extending from the inner shell member 101; or in other embodiments, when the metal shell 1 is designed as a one - piece, the welding portion 121 can be directly formed by extending from the side plate member 12 of the metal shell 1.
[0054] In a preferred embodiment of the present application, the anti - reverse - insertion portion 5, the welding portion 121 and the outer side plate 1022 are formed by drawing from the same metal sheet. The connection positions of any two of the anti - reverse - insertion portion 5, the welding portion 121 and the outer side plate 1022 are seamlessly joined. In this way, the structural strength of the anti - reverse - insertion portion 5 can be increased, making it difficult for the anti - reverse - insertion portion 5 to be pushed and deformed. Even if the anti - reverse - insertion portion 5 is pushed and deformed by a large force, the influence on the outer top plate 1021 and the inner top plate 1011 can be reduced. In a preferred embodiment, one anti - reverse - insertion portion 5 is formed on each of the two outer side plates 1022 on both sides of the outer top plate 1021.
[0055] Please refer to Figures 3 to 7 As shown, an elastic arm 111 is formed by stamping at a position near the rear end of the inner top plate 1011 and extending obliquely towards the insertion space 10 at one end. The elastic arm 111 extends obliquely in the front - rear direction. Specifically, the rear end of the elastic arm 111 is integrally connected to the inner top plate 1011 and extends obliquely forward and downward. The end of the card - ejecting rod 22 away from the operating rod 21 in the left - right direction has a first position at the frontmost end (that is, when the operating rod 21 is pushed backward to the limit position) and a second position at the rearmost end (that is, when the card holder 6 is inserted backward into the insertion space 10). Within the full - stroke rotation range of the card - ejecting rod 22, the elastic arm 111 always maintains elastic contact with the card - ejecting rod 22. Specifically: when the card - ejecting rod 22 is in the first position, the elastic arm 111 elastically presses downward against the rear - edge position of the upper surface of the card - ejecting rod 22; when the card - ejecting rod 22 is in the second position, the rear end of the elastic arm 111 elastically presses downward against the upper surface of the card - ejecting rod 22. This enables the card - ejecting rod 22 not to shake and make abnormal noises within the full - stroke rotation range, and at the same time ensures that the end of the card - ejecting rod 22 away from the operating rod 21 in the left - right direction contacts the card holder 6 stably, avoiding the occurrence of contact misalignment in the up - down direction.
[0056] Please refer to Figures 2 to 8 As shown, in the present application, the terminal assembly 300 is an independent module. The terminal assembly 300 itself is not fixed to the metal housing 1. The terminal assembly 300 is independently welded and fixed to the docking circuit board 200. The metal housing 1 covers the terminal assembly 300 and is independently fixed to the docking circuit board 200. In a preferred embodiment, a limiting portion 33 is further formed by extending the rear end position of the insulating body 31 further backward. When the card ejecting lever 22 is in the first position or the second position, at least a part of the end of the card ejecting lever 22 away from the operating lever 21 in the left-right direction is located directly above the limiting portion 33, so that it can provide support for the downward swing of the end of the card ejecting lever 22 away from the operating lever 21 in the left-right direction to a certain extent. In addition, it can ensure that the end of the card ejecting lever 22 away from the operating lever 21 in the left-right direction is in stable contact with the card tray 6, and avoid the occurrence of misalignment in the up-down direction contact.
[0057] Furthermore, in a preferred embodiment, mating grooves 61 extending in the front-rear direction are formed at the lower surface positions on the left and right sides of the card tray 6. When the card tray 6 is inserted into the insertion space 10 in the forward direction, the anti-reverse insertion portion 5 is slidably received in the mating grooves 61. When the card tray 6 is inserted into the insertion space 10 in the reverse direction, the two side positions of the insertion end edge of the card tray 6 abut against and are stopped by the anti-reverse insertion portion 5.
