[0032] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] Please refer to Figure 1 The present embodiment provides an information card plug-in assembly 100, comprising a base 110, an information card 120, and a protective cover 130; a gold finger 121 is provided at the end of the information card 120; the protective cover 130 comprises a cover body 131 and an extension plate 132 connected to each other; the information card 120 is fixedly connected to the cover body 131, and the extension plate 132 extends toward the gold finger 121 and has a preset distance from the information card 120; a slot 111 is defined on the side of the base 110 facing the gold finger 121, and a metal pin 112 is provided in the slot 111 corresponding to the gold finger 121; when the gold finger 121 is horizontally inserted into the slot 111, the extension plate 132 contacts the upper surface of the base 110 in the horizontal direction and slides in to partially cover the upper surface of the base 110, so that the gold finger 121 can be electrically connected to the metal pin 112.

[0034] Specifically, the information card plug-in assembly 100 includes a base 110 and an information card 120. It should be noted that the information card 120 of the present application can be a quantum cryptography card or other card capable of information transmission. Preferably, the information card 120 of the present application is a quantum cryptography card, a highly secure hardware device used for data encryption, decryption, authentication, and other operations to ensure the security of information transmission and data integrity.

[0035] like Figure 6 As shown, a slot 111 is provided on one side of the base 110, and a metal pin 112 is provided in the slot 111; correspondingly, as shown in FIG. Figure 5 As shown, a gold finger 121 is provided at the end of the information card 120 , and the end of the information card 120 can be inserted into the slot 111 so that the gold finger 121 is electrically connected to the metal pin 112 .

[0036] Because the information card of the existing information card insertion assembly does not have a component that can guide and limit the insertion direction of the information card when it is inserted into the base, the information card may be inserted into the slot of the base at an angle. This insertion and removal method is likely to cause stress contact between the information card and the base, which may scratch or damage the gold fingers, thereby reducing the stability of the electrical connection between the information card and the base and the reliability of information transmission.

[0037] In order to solve the above problems, Figure 4 As shown, the information card plug-in assembly 100 of the present application also includes a protective cover 130, which includes a cover body 131 and an extension plate 132. The cover body 131 is arranged on the board surface of the information card 120. In order to avoid the setting of the cover body 131 affecting the process of inserting the information card 120 into the slot 111, there is a preset gap between the edge of the cover body 131 facing the base 110 and the gold finger 121 to ensure that the gold finger 121 can be fully inserted into the slot 111.

[0038] like Figure 4As shown, the extension plate 132 is disposed on an edge of the cover 131 away from the information card 120, with a preset spacing between the extension plate 132 and the information card 120. Preferably, the thickness of the cover 131 is spaced apart from the extension plate 132 to prevent the extension plate 132 from interfering with the insertion of the information card 120 into the slot 111. Simultaneously, the extension plate 132 extends toward the base 110, such that the preset spacing from the extension plate 132 to the base 110 is less than or equal to the preset spacing from the information card 120 to the base 110. In this case, the length of the extension plate 132 along the insertion and removal direction of the information card 120 is greater than or equal to the length of the gold finger 121. Preferably, the extension plate 132 and the cover 131 are both made of metal and are integrally formed. With this arrangement, if the information card 120 is inserted into the slot 111 at an angle, the extension plate 132 prevents the gold fingers 121 from contacting the metal pins 112 of the slot 111. The extension plate 132 guides and limits the insertion direction of the information card 120, ensuring that the information card 120 is always inserted horizontally into the base 110. The information card 120 is inserted horizontally into the slot 111 of the base 110, so that the gold fingers 121 make electrical contact with the metal pins 112. The extension plate 132 covers the top surface of the base 110. When the information card 120 is removed from the slot 111, the extension plate 132 covers the top surface of the base 110, abutting against the base 110 and preventing the information card 120 from tilting. This ensures that the information card 120 is always removed horizontally from the base 110.

[0039] It should be noted that, in one possible embodiment of the present application, the preset interval between the extension plate 132 and the base 110 is equal to the preset interval between the information card 120 and the base 110, that is, the end of the extension plate 132 is flush with the end of the information card 120. Such an arrangement can reduce production costs while ensuring that the information card 120 is horizontally plugged and unplugged in the base 110; in another possible embodiment of the present application, the preset interval between the extension plate 132 and the base 110 is smaller than the preset interval between the information card 120 and the base 110, that is, the length of the extension plate 132 along the plugging and unplugging direction of the information card 120 is greater than the length of the gold finger 121 along the plugging and unplugging direction. Such an arrangement can increase the length of the extension plate 132 covering the top surface of the base 110 while ensuring that the information card 120 is horizontally plugged and unplugged in the base 110, thereby improving the stability of the connection between the information card 120 and the base 110.

[0040] The present application provides an information card plug-in assembly 100, comprising a base 110, an information card 120, and a protective cover 130; the end of the information card 120 has a gold finger 121, and the protective cover 130 includes a cover body 131 and an extension plate 132 connected to each other. The information card 120 is fixedly connected to the cover body 131, and the extension plate 132 extends toward the side of the gold finger 121 and has a preset distance from the information card 120. Due to the arrangement of the extension plate 132, when the information card 120 is inserted into the base 110, it cannot be inserted at an angle and can only be kept in contact with the base 110. 0, thereby preventing the gold finger 121 from being scratched or damaged by stress caused by the tilted insertion of the information card 120 into the base 110. A slot 111 is defined on the side of the base 110 facing the gold finger 121. Slot 111 contains metal pins 112 corresponding to the gold finger 121. When the gold finger 121 is inserted horizontally into slot 111, the extension plate 132 horizontally contacts the upper surface of the base 110 and slides in to partially cover the upper surface of the base 110, allowing the gold finger 121 to electrically connect with the metal pins 112. The above-described information card insertion and removal assembly 100 ensures that the information card 120 is always inserted or removed horizontally from the base 110, preventing scratches or damage to the gold finger 121 and improving the reliability and stability of information transmission.

[0041] In one embodiment of the present application, the orthographic projection outline of the extension plate 132 on the information card 120 has an overlapping area with the outer outline of the information card 120 .

[0042] Specifically, the extension plate 132 is disposed on an edge of the cover 131 away from the information card 120 and extends toward the base 110. In a specific embodiment of the present application, as shown in FIG. Figure 4 As shown, the projection area of ​​the extension plate 132 completely covers the projection area of ​​the gold finger 121. At this time, the relative distance between the extension plate 132 and the base 110 is smaller than the relative distance between the gold finger 121 and the base 110, thereby improving the stability and efficiency of the extension plate 132 in guiding the insertion and removal direction of the information card 120, while also improving the protection of the gold finger 121.

[0043] Alternatively, in another specific embodiment of the present application, the relative distance between the extension plate 132 and the base 110 is equal to the relative distance between the gold finger 121 and the base 110, the width of the extension plate 132 is equal to the width of the gold finger 121, and the width direction is perpendicular to the insertion and removal direction of the information card 120. In this case, the projected area of ​​the extension plate 132 partially covers the projected area of ​​the gold finger 121 (not shown in the figure);

[0044] Alternatively, in another specific embodiment of the present application, the relative distance between the extension plate 132 and the base 110 is smaller than the relative distance between the gold finger 121 and the base 110, and the width of the extension plate 132 is smaller than the width of the gold finger 121, and the width direction is perpendicular to the insertion and removal direction of the information card 120. In this case, the projected area of ​​the extension plate 132 partially covers the projected area of ​​the gold finger 121 (not shown in the figure);

[0045] Alternatively, in another specific embodiment of the present application, the relative spacing between the extension plate 132 and the base 110 is equal to the relative spacing between the gold finger 121 and the base 110, and the width of the extension plate 132 is smaller than the width of the gold finger 121. In this case, the projected area of ​​the extension plate 132 partially covers the projected area of ​​the gold finger 121 (not shown in the figure). The present application does not impose any restrictions on the specific projected area of ​​the extension plate 132, as long as it can achieve the guiding and limiting function during the insertion and removal of the information card 120.

[0046] Alternatively, as Figure 3 As shown, the cover body 131 includes a top plate 1311 and a first side wall 1312, a second side wall 1313, a third side wall 1314 and a fourth side wall 1315 respectively connected perpendicularly to the side edges of the top plate 1311; the top plate 1311 is fixedly connected to the information card 120 through the first side wall 1312, the second side wall 1313, the third side wall 1314 and the fourth side wall 1315 so that the top plate 1311 is parallel to the information card 120.

[0047] Specifically, if Figure 3 As shown, the cover 131 includes five sides, formed into a rectangular frame by a first side wall 1312, a second side wall 1313, a third side wall 1314, and a fourth side wall 1315. The top plate 1311 is disposed on the side of the rectangular frame away from the information card 120, so that a receiving cavity is formed in the middle of the cover 131. Preferably, the five sides of the cover 131 are integrally formed.

[0048] In one possible implementation of the present application, a soldering pad (not shown in the figure) is provided on the board surface of the information card 120 facing the protective cover 130, and the first side wall 1312, the second side wall 1313, the third side wall 1314 and the fourth side wall 1315 are welded to the information card 120 through the soldering pad to improve the connection stability between the protective plate and the information card 120.

[0049] Optionally, the protective cover 130 is made of metal.

[0050] With this arrangement, the protective cover 130 provided on the information card 120 can provide a certain electromagnetic shielding protection for the information card 120 . At the same time, the protective cover 130 can be in contact with the chip of the information card 120 to conduct heat, thereby facilitating the heat dissipation of the chip and improving the reliability of the information card 120 .

[0051] In one embodiment of the present application, Figure 2 As shown, an observation window 133 is provided on the side of the extension plate 132 facing the gold finger 121, and the gold finger 121 can be at least partially exposed through the observation window 133. The provision of the observation window 133 allows the operator to observe the contact between the gold finger 121 and the metal pin 112 of the base 110, making the insertion and removal process of the base 110 and the information card 120 more controllable, efficient, and reliable.

[0052] Specifically, if Figure 2 and Figure 3 As shown, in a specific embodiment of the present application, the observation window 133 is a through slot 1331 provided on the edge of the extension plate 132. The through slot 1331 extends along the insertion and removal direction of the information card 120 to the edge of the extension plate 132 to communicate with the outside, and the gold finger 121 can be at least partially exposed through the through slot 1331.

[0053] It should be noted that the number of the through slots 1331 can be one or more; when the number of the through slots 1331 is one, the through slot 1331 has a preset width to ensure that the gold finger 121 is exposed, wherein the width direction of the through slot 1331 is perpendicular to the insertion and removal direction of the information card 120; when the number of the through slots 1331 is multiple, such as Figure 3 As shown, multiple through slots 1331 are arranged in parallel and spaced apart. The present application does not impose any limitation on the specific number of through slots 1331, as long as the contact between the gold finger 121 and the metal pin 112 of the base 110 can be observed through the through slots 1331.

[0054] Furthermore, in order to prevent dust and protect the gold finger 121, a transparent plate (not shown in the figure) can be provided on the surface of the through groove 1331, and the operator can observe the contact between the gold finger 121 and the metal needle 112 of the base 110 through the transparent plate.

[0055] In another specific embodiment of the present application, the extension plate 132 is a transparent plate, and the operator can fully observe the insertion and removal process of the gold finger 121 and the connection status with the metal needle 112 through the extension plate 132 .

[0056] Alternatively, see Figure 2 、 Figure 5 and Figure 6To ensure that the protective cover 130 and the information card 120 can be precisely assembled with the base 110 when the gold finger 121 of the information card 120 is inserted into the slot 111 of the base 110, a positioning post 113 is further provided in the slot 111 of the base 110. Correspondingly, a first positioning groove 1332 is defined on an edge of the extension plate 132 of the protective cover 130 facing the base 110, and a second positioning groove 122 is defined on an edge of the information card 120 facing the base 110. When the gold finger 121 of the information card 120 is inserted into the slot 111 of the base 110, the positioning post 113 can be precisely engaged in the first positioning groove 1332 and the second positioning groove 122, thereby improving the connection stability and assembly accuracy of the information card 120 and the protective cover 130 to the base 110 respectively.

[0057] Another aspect of the present application provides a functional module comprising a main body and an information card plug-in assembly 100. The information card plug-in assembly 100 comprises a base 110 and an information card 120. The base 110 is disposed on the main body, and the information card 120 can be plugged into and removed from the base 110 in a direction parallel to the main body. The specific structure and beneficial effects of the information card plug-in assembly 100 have been described in detail above and will not be repeated here. The above-mentioned functional module, through the provision of the information card plug-in assembly 100, prevents the gold finger 121 of the information card 120 from being scratched or damaged, thereby improving the reliability and stability of information transmission.

[0058] The above description is merely an optional embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
