[0043] Please refer to Figures 1 to 10 As shown, a card cover assembly and a card connector disclosed in the present application are shown. The card connector includes a circuit board assembly 4, a card cover assembly (not numbered) welded and fixed on the circuit board assembly 4, and a terminal module 3 used in conjunction with the card cover assembly. In this embodiment, the terminal module 3 is three independent tofu block modules, namely two SIM card modules and one Micro SD card module, and of course it can also be one of the card modules or other card modules. The terminal module 3 includes an insulating base 31 and a plurality of signal terminals 32 fixed in the insulating base 31, each of the signal terminals 32 includes a terminal fixing section 321 fixed in the insulating base 31, a terminal docking section 322 protruding out of the insulating base 31, and a terminal elastic contact section 323. The terminal docking section 322 is welded and fixed to the circuit board assembly 4. The terminal elastic contact section 323 is used to make electrical contact with the inserted electronic card.

[0044] The metal cover 1 is formed by stamping and bending a metal plate, and includes a top plate 11 and side plates 12 formed by extending downward from the two side edges of the top plate 11. The top plate 11 and the side plates 12 define an insertion space 110 together, and the insertion space 110 forms an insertion port 10 at one end. Further, the metal cover 1 has an extension portion 14 extending outward in a lateral direction on one side close to the insertion port 10. The extension portion 14 includes a top wall 141 and a snap-on wall 142 formed by extending downward from both ends of the top wall 141 in the front-to-back direction. In the embodiment of the present application, the extension portion 14 is formed by extending from the top plate 11. Of course, in other embodiments, the extension portion 14 can also be formed by bending and extending from the side plate 12. In the embodiment of the present application, the top wall 141 is coplanar with the top plate 11. Of course, in other embodiments, the top wall 141 and the top plate 11 can also be designed to be stepped and not coplanar.

[0045] Please refer to Figures 4 to 10As shown, the main body 15 is formed by integral injection molding of an insulating material, and the main body 15 is fixed below the extension portion 14. Specifically, the main body 15 includes a bottom wall 151, a first side wall 1521 and a second side wall 1522 formed by extending upward from both ends of the bottom wall 151 in the front-back direction, and a stop wall 153 formed by extending upward from the bottom wall 151 along the lateral direction on a side close to the insertion space 110. The top wall 141 covers the upper edge of the first side wall 1521 and the second side wall 1522 and forms an active cavity 150 together with the main body 15. The buckle wall 142 is respectively attached to the outer surface of the first side wall 1521 and the second side wall 1522 and is buckled and fixed to the first side wall 1521 and the second side wall 1522. Specifically, the outer surfaces of the first side wall 1521 and the second side wall 1522 protrude to form a boss portion (not numbered), and the buckle wall 142 is penetrated along the front-to-back direction to form a buckle hole (not numbered), and the boss portion is buckled and fixed with the buckle hole.

[0046] Furthermore, it includes a card ejection rod 16, which is rotatably arranged in the movable cavity 150. Specifically, the card ejection rod 16 is clamped between the main body 15 and the extension portion 14 in the up-down direction, and the middle position of the card ejection rod 16 is rotatably connected between the main body 15 and the extension portion 14. One embodiment may be that a rotating shaft portion 17 is provided, and the rotating shaft portion 17 passes through the top wall 141, the card ejection rod 16 and the bottom wall 151 respectively, so as to rotatably connect the card ejection rod 16 between the main body 15 and the extension portion 14. One embodiment may specifically be that the rotating shaft portion 17 realizes the above-mentioned rotatable connection by riveting.

[0047] Please refer to Figures 4 to 10As shown, along the front-to-back direction, one end of the buckle wall 142 located at the front end in the transverse direction is folded back and extended to form an elastic arm 143. The card cover assembly also includes a fixed terminal 18. The fixed terminal 18 is fixed in the main body 15. The fixed terminal 18 includes a fixed section 181 fixed to the main body 15, a docking section 182 protruding out of the main body 15, and a contact section 183 exposed outside the main body 15. The fixed terminal 18 is fixed in the main body 15 by integral injection molding. Specifically, the fixed section 181 includes a portion buried in the bottom wall 151 and a portion buried in the second side wall 1522. The docking section 182 is formed by extending downward from the fixed section 181 buried in the bottom wall 151. The docking section 182 is located in the middle of the bottom wall 151. The contact section 183 is formed by extending from the fixed section 181 buried in the second side wall 1522. The elastic arm 143 can be elastically swung along the front-back direction and elastically overlap the contact section 183. Specifically, the free end of the elastic arm 143 overlaps the front surface of the contact section 183.

[0048] The card ejection rod 16 is located at the rear end of the elastic arm 143, and the rotation of the card ejection rod 16 drives the elastic arm 143 to disconnect from the contact segment 183. Specifically, in normal state (when the card tray assembly is not inserted into the insertion space), the free end of the elastic arm 143 is in conductive contact with the front surface of the contact segment 183. When the card tray assembly is fully inserted into the insertion space 110, the card tray assembly pushes the card ejection rod 16 forward, and the card ejection rod 16 further pushes the elastic arm 143 forward, thereby driving the elastic arm 143 to disconnect from the contact segment 183, and realizing the switch detection function.

[0049] Please refer to Figure 5 , Figure 7 and Fig.10 As shown, specifically, the bottom wall 151 extends upward along the transverse direction at a side close to the insertion space 110 to form a stop wall 153, and a notch 1501 is formed between the front end of the stop wall 153 and the end of the first side wall 1521 close to the insertion space 110 in the transverse direction, and one end of the card ejection rod 16 is exposed from the notch 1501. The card tray assembly 2 is formed with a stop surface 21 (specifically, the stop surface 21 is formed by a boss formed by one side of the card tray assembly protruding outward), and when the card tray assembly 2 is fully inserted into the insertion space 110, the stop surface 21 stops at the front end of the stop wall 153. One end of the card ejection rod 16 contacts the card tray assembly 2 through the notch 1501, and specifically, one end of the card ejection rod 16 contacts the stop surface 21 through the notch 1501.

[0050] In the present application, the extension portion 14, the main body 15 and the card ejection rod 16 are all located on one lateral side of the insertion space 110. This can prevent the elastic arm 143 and the card ejection rod 16 from affecting the electronic card carried in the card tray assembly 2. Rotating and assembling the card ejection rod 16 at the insertion port 10 can simplify the card ejection mechanism structure, and only one card ejection rod 16 is required to realize the card ejection function. The stop wall 153 is formed on the main body 15, which can realize the insertion stop of the card tray assembly, so that the stop surface 21 used for the insertion stop is synchronously used as the driving surface for driving the card ejection rod 16 to rotate, thereby improving the insertion accuracy of the card tray assembly 2 and improving the detection accuracy of the switch function composed of the elastic arm 143 and the contact section 183.

[0051] Please refer to Figure 5 , Figure 7 and Fig.10 As shown, in order to achieve the firm assembly of the main body 15 and the extension portion 14, the top wall 141 is bent downward to extend a fixing plate 144, and the stop wall 153 is formed with a fixing hole 1531 that passes through the upper and lower directions corresponding to the position of the fixing plate 144. The fixing plate 144 passes through the fixing hole 1531 and protrudes downward from the lower surface of the bottom wall 151 and is welded and fixed to the circuit board assembly 4.
