[0002] For related prior art, please refer to China Invention Patent Publication No. CN202210154171.4, which discloses a card cover and a card connector thereof, wherein the card cover includes a metal shell and a card ejection mechanism combined with the metal shell. The metal shell is made by stamping and bending a metal plate, and includes a flat top plate, a side plate formed by bending down the two end edges of the top plate along the left and right directions, and an end plate formed by bending down one end edge of the top plate along the front and rear directions. Among them, the top plate of the metal shell, the side plate away from the limit plate in the left and right directions, and the limit plate jointly define a plug-in space and form an insertion port for inserting an insertion component. Among them, the fixed terminal in the switch terminal and the card ejection member in the card ejection mechanism are integrated and fixed at the rear end position of the metal shell through a fixed block. However, when the card tray is inserted into the plug-in space, the end of the card tray will hit the front end face of the fixed block, thereby causing the fixed block to deviate or loosen from the metal shell to produce abnormal noise, and cause problems such as poor contact of the switch terminal.

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.

[0034] Please refer to Figures 1 to 6 As shown, a card connector disclosed in the present application includes a card cover assembly 101, a terminal module 6 matched with the card cover assembly 101, and a card tray 102 (insertion module). The card cover assembly 101 includes a metal shell 1, a switch terminal member (unnumbered) and a card ejection mechanism (unnumbered). The metal shell 1 is formed with a top plate 11, side plates 12 formed by extending downward from both sides of the top plate 11 along the left and right directions, and an end plate 13 formed by extending downward from the rear end edge of the top plate 11 in the front-to-back direction perpendicular to the left and right directions. The top plate 11, the side plate 12, and the end plate 13 are jointly arranged to form a plug-in space 10, and the plug-in space 10 forms an insertion port (unnumbered) at one end away from the end plate 13 in the front-to-back direction.

[0035] Please refer to Figure 2 and Figure 3 As shown, the terminal module 6 includes an insulating base 61 and a plurality of signal terminals 62, each of the signal terminals 62 includes a fixed section (unnumbered) buried and fixed in the insulating base 61, an elastic contact section (unnumbered) further extended from the fixed section and correspondingly protruding into the plug-in space 10, and a docking foot (unnumbered) further extended from the fixed section and correspondingly protruding out of the insulating base 61 for docking with an electrical connector of a substrate (not shown, which may be a PCB board); the card cover assembly 101 is correspondingly covered above the terminal module 6, and the plug-in space 10 is formed between the inner surface (that is, the lower surface) of the top plate 11 and the upper surface of the insulating base 61.

[0036] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the top panel 11 is bent downward near the end panel 13 in the front-to-back direction and extends backward to form a step portion 14, so that the upper surface and the lower surface at the rear end of the top panel 11 are both stepped, which can effectively enhance the structural strength of the rear end of the metal shell 1. A clearance space can also be formed above the step portion 14 to make room for other components inside the electronic device. The inner surface (that is, the lower surface) of the top panel 11 is formed with a stop surface 110 facing the front end at the step portion 14, and the stop surface 110 is used to stop the insertion of the card tray 102. Furthermore, in a preferred embodiment, along the left-right direction, the step portion 14 covers the full width of the top panel 11.

[0037] Please refer to Figure 2 , Figure 3 ,and Figure 6 As shown, the switch terminal member includes an insulating member 21 and a fixed terminal member 22. The insulating member 21 is fixed to the lower surface of the step portion 14. The fixed terminal member 22 includes a fixed portion (unnumbered) embedded and fixed in the insulating member 21, a contact portion (unnumbered) exposed outside the insulating member 21, and a docking pin (unnumbered) extending and protruding outside the insulating member 21. In the present application, the insulating member 21 does not exceed the stop surface 110 forward in the front-to-back direction. When the card tray 102 is completely inserted into the plug-in space 10, the front edge of the card tray 102 in the insertion direction stops at the stop surface 110 and cannot be further inserted in the insertion direction to push the insulating member 21. The preferred embodiment is that the insulating member 21 is located behind the stop surface 110 in the front-to-back direction. Furthermore, the end plate 13 is folded forward and to the left and right to form an elastic contact piece 23, and the elastic end of the elastic contact piece 23 elastically abuts against the contact portion of the fixed terminal piece 22. The elastic contact piece 23 forms a contact point 231 that extends forward along the front-to-back direction beyond the stop surface 110, and the contact point 231 is used for the insertion and pushing of the card holder 102. The elastic contact piece 23 contacts or disconnects with the fixed terminal piece 22 to form a switch function.

[0038] The card ejection mechanism includes a card ejection rod 31 and a card pusher 32; the card ejection rod 31 is assembled on one side of the metal housing 1 and can be reciprocated relative to the metal housing 1 in the front-rear direction. The card pusher 32 is rotatably riveted to the lower surface of the step portion 14 by a rivet 4. One end of the card ejection rod 31 is linked to one end of the card pusher 32.

[0039] Furthermore, the end of the card pushing member 32 away from the card ejection rod 31 is bent upward and extends in the left-right direction toward the end away from the card ejection rod 31 to form a bent portion 321. The step portion 14 is formed with a clearance hole 141 in the vertical direction corresponding to the position of the bent portion 321. The clearance hole 141 penetrates the stop surface 110 forward. The step portion 14 is formed with a convex portion 141 protruding downward at the position corresponding to the card pushing member 32. The convex portion 141 is pressed downward against the upper surface of the card pushing member 32 to limit the card pushing member 32. In this way, the contact stability between the card pushing member 32 and the card tray 102 is improved.

[0040] Of course, in other embodiments, the terminal module 6 can also be fixedly integrated onto the inner surface of the top plate 11 (specifically, the insulating base 61 is integrally formed or assembled and fixed with the top plate 11), and the insulating base 61 does not extend backward beyond the stop surface 110 in the front-to-back direction, and the plug-in space 10 is formed below the lower surface of the insulating base 61.

[0041] The present application forms a step portion 14 and a stop surface 110 at the rear end of the top plate 11 of the metal shell 1, thereby improving the structural strength of the metal shell 1, and can also be used for the insertion stop of the card tray 102 to prevent the card cover assembly 101 from being damaged by excessive insertion of the card tray 102.

[0042] The socket electrical connector disclosed in the present application can better save manufacturing costs, which is specifically manifested in improving the utilization rate of metal raw material plates and facilitating miniaturized design.

[0043] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
