[0002] The current size of Nano SIM in the market is about 12mm x 9mm. Its smaller size is intended to make room for certain components of smart mobile terminals, and to help smart mobile terminals develop in a lighter and thinner direction. Currently, as users pursue low-weight smart mobile terminals, most smart mobile terminal manufacturers are pursuing the maximum stacking of electrical components in a limited space to achieve more effective space utilization.

[0003] Due to the extreme pursuit of the internal space of mobile smart terminals, the space occupied by the Nano SIM card holder is too large, so the holder pursues the ultimate smallness to meet customer needs. Although there is currently an eSIM compared to the mature physical SIM card, the security of the eSIM card is still unknown. Therefore, it is foreseeable that as nano SIM cards become more and more popular, eSIM cards will still need to go through a long period of market testing to become the successor of nano SIM cards. Therefore, a smaller Mini Nano SIM card is needed. The Mini Nano SIM card is a smaller SIM card obtained by further cutting on a conventional SIM card, and conventional SIM cards are difficult to match with Mini Nano SIM cards to achieve a smaller size, so a Mini Nano SIM card holder is urgently needed.

[0040] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0041] See also Figures 1 to 9 As shown, a Mini Nano SIM card holder of the utility model comprises a base unit 1; the base unit 1 comprises an insulating base 11 for accommodating an external Mini Nano SIM card, and a plurality of terminals 12 arranged on the insulating base 11;

[0042] The terminal 12 is provided with a solder foot 13, and the solder feet 13 of multiple terminals 12 form two solder foot rows. The solder feet 13 of the terminals 12 in the two solder foot rows are staggered. The multiple solder feet 13 are staggered to make the solder foot rows occupy a smaller size space, thereby facilitating the reduction of the size space of the insulating base 11.

[0043] Specifically, the Mini Nano SIM card is a smaller SIM card obtained by further cutting the regular SIM card. For specific cutting dimensions, please refer to the attached figure in the specification. Figure 7 , Figure 8 As shown, it is worth noting that the Mini Nano SIM card is cut to achieve a smaller size, and the cut size should not be a limitation on the Mini Nano SIM card holder provided in this embodiment.

[0044] Specifically, by staggered arrangement of multiple solder feet 13, the solder foot row can occupy a smaller space. In this way, the size of the insulating base can be reduced accordingly, thereby achieving a compact design in overall size. This is very beneficial for scenarios where the Mini Nano SIM card holder needs to be used in devices with limited space, thereby improving the practicality of the Mini Nano SIM card holder.

[0045] Specifically, the Mini Nano SIM card holder also includes a supporting seat unit 2 and a push rod unit 3 used in conjunction with the base unit 1; the supporting seat unit 2 includes a card tray 21 for accommodating an external Mini Nano SIM card, the insulating base 11 has a first slot body 15 for accommodating the card tray 21, and the push rod unit 3 is used to drive the card tray 21 to move in the first slot body 15 to protrude out of the insulating base 11.

[0046] Specifically, the terminal 12 is provided with an elastic contact portion, and the free end of the elastic contact portion forms an arc-shaped protrusion for conducting the Mini Nano SIM card in the insulating base 11; by allowing the free end of the elastic contact portion of the terminal 12 to protrude into the first groove body 15, it can be ensured that the electrical connection between the terminal and the Mini Nano SIM card is more reliable, and the protrusion of the free end can ensure better contact between the terminal and the SIM card, reducing interference and loss in signal transmission, and the elastic contact portions of multiple terminals 12 are arranged around all solder feet 13 of two solder foot rows.

[0047] Specifically, the terminal 12 has a holding portion inserted into the insulating base 11, the holding portion includes a board body and two holding feet protruding from the board body, the solder foot 13 protrudes from the board body, the two holding feet protrude from the board body in different directions, and the two holding feet are used to further stabilize the holding portion and thereby improve the stability of the Mini Nano SIM card holder.

[0048] Specifically, two solder pin rows are arranged in the middle position of the insulating base 11. The cross-arranged solder pin rows can optimize the layout space of the SIM card holder. By arranging the solder pin rows in the middle position of the insulating base and cross-arranging the solder pins 13 on the terminals 12 on both sides of the two solder pin rows, the space can be used more effectively and the size of the SIM card holder can be reduced, thereby adapting to a more miniaturized device design.

[0049] Specifically, the push rod unit 3 includes a third rod body 31 and a push portion 32 formed by bending and extending from the third rod body 31 to one end away from the card tray 21. A second opening 22 is also provided on the card tray 21. The external card pin contacts the push portion 32 through the second opening 22 to push the third rod body 31 to move. By opening the second opening 22 on the card tray 21 and making the card pin contact the push portion 32 through the opening, a compact design of the push rod unit can be achieved. This design can save space, adapt to miniaturized equipment design, and improve the flexibility and usability of the overall equipment.

[0050] Specifically, the card holder also includes a rotating rod unit 4, which is rotatably set on the insulating base 11. The rotating rod unit 4 includes a second rod 42 used in conjunction with the third rod 31 and a first rod 41 for pushing the card tray 21 out. The third rod 31 is provided with a connecting portion 33 for accommodating the second rod 42. The third rod 31 pushes or pulls the second rod 42 via the connecting portion 33. The rotating rod unit 4 has the functions of pushing the card tray and cooperating with the third rod, reducing the number and complexity of components. This simplified structure helps to reduce manufacturing costs, improve assembly efficiency, and reduce the possibility of failure and maintenance.

[0051] Specifically, the SIM card holder also includes a housing unit 5 used in conjunction with the insulating base 11, the insulating base 11 is provided with a protrusion 16, the housing unit 5 includes a cover 51, and a sixth groove 52 for accommodating the protrusion 16 on the cover 51, the cover 51 is arranged on the insulating base 11 via the protrusion 16 and the sixth groove 52, the housing unit 5 is used in conjunction with the insulating base 11 through the protrusion 16 and the sixth groove 52, and can provide stable support, and the design of the protrusion 16 and the sixth groove 52 can ensure that the cover 51 is on the insulating base 11 The position is fixed and not prone to shaking or shifting. This stable support helps to protect the internal structure and connector of the SIM card holder and improve its reliability and durability. The sixth groove 52 opened on the cover body 51 is used to accommodate the protrusion 16, which can conveniently connect the cover body 51 to the insulating base 11. This design makes the installation and removal of the SIM card holder more convenient and quick, without the need for additional tools or complicated operating steps. The user only needs to align the cover body 51 with the insulating base 11, and the installation and removal can be completed through the cooperation of the protrusion 16 and the sixth groove 52.

[0052] Specifically, a fourth slot 24 is provided on the card tray 21, and a first elastic arm 53 is provided on the cover 51 or the insulating base 11. The first elastic arm 53 is used to limit the movement of the card tray 21 by contacting the inner wall of the fourth slot 24. The first elastic arm 53 can provide a stable limiting effect by contacting the fourth slot 24. When the card tray 21 moves, the first elastic arm 53 will be subjected to pressure, thereby contacting the inner wall of the fourth slot 24. This limiting effect can ensure that the card tray 21 maintains a stable position during movement, avoiding excessive movement or deviation from a predetermined position; by limiting the movement of the card tray 21, the first elastic arm 53 can prevent the card tray 21 from loosening or falling off during use. When the card tray 21 is subjected to external force or vibration, the contact effect of the first elastic arm 53 can provide additional support and fixation to prevent the card tray 21 from accidentally moving or detaching.

[0053] Specifically, the insulating base 11 is further provided with a second slot 17 for accommodating the third rod 31 . The third rod 31 is slidably disposed on the insulating base 11 via the second slot 17 , so that the insulating base 11 provides stable support for the third rod 31 .

[0054] Specifically, a second elastic arm 54 is further provided on the cover body 51 or the insulating base 11, and a fifth groove body 34 for accommodating the second elastic arm 54 is opened on the third rod body 31. The second elastic arm 54 is used to limit the movement of the third rod body 31 by contacting the inner wall of the fifth groove body 34. The existence of the second elastic arm 54 can limit the movement range of the third rod body 31, which helps to ensure that the third rod body 31 remains stable at a specific position or angle, prevents accidental shaking or movement, and is used to maintain the stability of the Mini NanoSIM card holder.

[0055] Specifically, a Mylar sheet 55 is further provided on the side of the cover body 51 away from the terminal 12. The Mylar sheet 55 is used to provide an absorption plane for the subsequent patch process. The Mylar sheet 55 is Mylar, which is a polyester film material commonly used in insulation, protection and isolation applications in electronic products. Mylar can provide a flat surface for the subsequent patch process to better absorb and fix other components. In electronic manufacturing, the patch process is the process of pasting various electronic components (such as resistors, capacitors, integrated circuits, etc.) on a printed circuit board (PCB). In order to ensure the correct installation and reliability of the components, a flat surface is required to provide a reference for adhesion and fixation. The patch process usually uses adhesives or welding technology to fix the components on the PCB. Pasting a piece of Mylar film on the SIM card holder can provide a flat surface so that the subsequent patch process can better absorb and fix the components. The Mylar film has the characteristics of flatness, smoothness and insulation, and can provide a stable reference to ensure the correct installation and reliability of the components. This can improve the accuracy and reliability of the patch process and reduce possible manufacturing defects and failure risks.
