[0037] 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.

[0038] In this application description, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] Furthermore, for the sake of accuracy, all directions mentioned throughout this application shall be referred to as... Figure 1 For reference, the X-axis direction is defined as the insertion and removal direction of the insertion module 9, with the positive X-axis direction being the removal direction of the insertion module 9; 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.

[0041] Please refer to the following: Figure 1 and Figure 4The image shows a card connector disclosed in this application. The card connector includes a card cover (not labeled) and a terminal assembly 3 that mates with the card cover. The card cover includes a metal housing 1 and a card ejection structure 2 that mates with the metal housing 1. The metal housing 1 has 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 a insertion space 10 and an insertion port 101 for inserting a module 9 at one end. The terminal assembly 3 has an insulating body 31 and a plurality of terminals 32 fixed to the insulating body 31. Each terminal 32 includes a fixed section (not labeled) embedded and fixed within the insulating body 31, a contact section 321 extending from the fixed section outside the insulating body 31 for electrical connection with a mating substrate (not shown), and an elastic contact section 322 extending from the fixed section and protruding into the insertion space 10 for elastic contact with the insertion module 9. In this embodiment, the insulating body 31 is integrally injection molded and fixedly attached to the inner side of the top plate 11. In other embodiments, the terminal assembly 3 can also be designed as an independent component. After the terminal assembly 3 is fixed to the mating substrate by welding, the card cover is placed above the periphery of the terminal assembly 3 and together with the terminal assembly 3, forms a card connector.

[0042] Furthermore, the card ejection mechanism 2 includes an operating lever 21 and a card ejection rod 22. The card ejection rod 22 is directly or indirectly rotatably connected to the front end of the metal housing 1 along the insertion direction of the insertion module 9. In this embodiment, the card ejection rod 22 is directly rotatably connected to the metal housing 1. Other embodiments are also possible, such as rotatably connecting the card ejection rod 22 to the insulating body 31.

[0043] Please refer to the reference. Figures 1 to 4 As shown, in a preferred embodiment of this application, the metal housing 1 further includes a first limiting wall 15. The plane of the first limiting wall 15 is spaced apart from the plane of the first side plate 12 in the left-right direction, forming an installation gap 150. The metal housing 1 also includes a first connecting wall 151, which connects and fixes the upper edge of the first limiting wall 15 in the up-down direction to the first side plate 12. The lower edge of the first limiting wall 15 in the up-down direction further extends to form a first mating portion 152. The first mating portion 152 is used for welding and fixing to a mating substrate. In a preferred embodiment, the first limiting wall 15 is located inside the first side plate 12 in the left-right direction.

[0044] The operating lever 21 is located within the installation gap 150 and is movable along the insertion / removal direction. The front end of the operating lever 21 along the insertion direction of the insertion module 9 is connected to the ejector lever 22. In use, by pushing the operating lever 21, the ejector lever 22 is rotated, causing the free end of the ejector lever 22 to push the insertion module 9 out of the insertion space 10, thus achieving the ejection function.

[0045] Please refer to Figure 2 and Figure 3 As shown, the first limiting wall 15 extends into a strip shape along the insertion / removal direction. The upper edges of both ends of the first limiting wall 15 along the insertion / removal direction are connected and fixed to the first side plate 12 via the first connecting wall 151. The lower edges of both ends of the first limiting wall 15 along the insertion / removal direction extend to form the first mating portion 152, which is directly opposite the first connecting wall 151 in the vertical direction.

[0046] In a preferred embodiment, the metal housing 1 further includes an outer limiting wall 16, which is spaced apart from the first limiting wall 15 along the left-right direction. The metal housing 1 also includes a second connecting wall 153, which integrally connects the lower edge of the outer limiting wall 16 to the lower edge of the first limiting wall 15. The outer limiting wall 16 and the first limiting wall 15 clamp the operating rod 21 along the left-right direction. The first side plate 12 extends along its lower edge in the up-down direction to form a second mating portion 121, which is used to fix it to the mating substrate.

[0047] In a preferred embodiment, the outer limiting wall 16 extends into a strip along the insertion / removal direction, and two second connecting walls 153 are provided. The two second connecting walls 153 are respectively connected to the two ends of the outer limiting wall 16 along the insertion / removal direction.

[0048] When the operating lever 21 is assembled into the mounting gap 150 and the cover is welded and fixed to the docking substrate, the first connecting wall 151, the first limiting wall 15, the first docking part 152, the first side plate 12, and the second docking part 121 surround the operating lever 21. The first docking part 152, which extends outward from the inner side of the insertion space 10, and the second docking part 121, which extends inward from the outer side of the insertion space 10, are correspondingly welded and fixed to the docking substrate. This prevents the operating lever 21 from deforming in the left-right direction when subjected to tilting thrust. In addition, the first limiting wall 15, which is close to the inner side of the operating lever 21, will not deform in the left-right direction. This prevents the first limiting wall 15 from deforming inward into the insertion space 10 even when the operating lever 21 is subjected to tilting thrust, thereby preventing it from colliding with the inserted insertion module 9 and causing malfunction.

[0049] In a preferred embodiment, the second connecting wall 153 is located above the plane of the first docking portion 152. In a more preferred embodiment, the second connecting wall 153 located at the rear end along the insertion direction of the insertion module 9 extends upward in the insertion direction of the insertion module 9 to form an elastic stop arm 154. The elastic stop arm 154 is cantilevered and its free end can swing vertically. When the operating lever 21 moves to the unplugged position along the insertion direction of the insertion module 9, the free end of the elastic stop arm 154 locks with the first locking notch 210 formed below the operating lever 21 to maintain the operating lever 21 in the unplugged position. Of course, in other embodiments, a second locking notch 210 may also be formed below the operating lever 21. When the operating lever 21 moves to the insertion completion position along the pull-out direction of the insertion module 9 (that is, when the insertion module 9 is fully inserted into the insertion space 10), the free end of the elastic stop arm 154 locks with the second locking notch 211 below the operating lever 21 to maintain the operating lever 21 in the insertion completion position.

[0050] In a preferred embodiment of this application, the metal housing 1 further includes a first locking spring 14. The first locking spring 14 extends into a strip shape along the insertion / removal direction, and its two ends along the insertion / removal direction are integrally connected to the top plate 11 and / or the first side plate 12. In the illustrated embodiment of this application, the two ends of the first locking spring 14 are integrally connected to the top plate 11. A first curved section 141 protrudes from the middle position of the first locking spring 14 along the insertion / removal direction into the insertion space 10, and the first curved section 141 is used to elastically abut against the insertion module 9 inserted into the insertion space 10. The first curved section 141 overlaps with the projection portion of the operating lever 21 in the vertical direction. This design facilitates the miniaturization of the overall card cover and ensures that the first locking spring 14 and the operating lever 21 do not interfere with each other.

[0051] In a preferred embodiment of this application, the first locking spring 14, the first side plate 12, and the outer limiting wall 16 are all located in the same extending plane. Furthermore, in this embodiment, two first locking springs 14 are provided, located on the side where the first side plate 12 is located and the side where the second side plate 13 is located, respectively.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.

[0053] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
