[0001] The present application relates to the technical field of memory card sockets, and in particular to a socket with an anti-drop structure. Background Art

[0002] With the intelligent upgrade of electronic devices, the market's requirements for electronic products are also constantly increasing. Memory cards are one of the indispensable data storage methods in people's lives. In order to facilitate the carrying of electronic devices and reduce the overall size of electronic devices, the space inside the electronic devices needs to be compressed, and the size of the memory card is also reduced accordingly. When the memory card is installed in the electronic device, it is usually necessary to use an anti-drop structure to fix the memory card on the card holder of the electronic device to keep the memory card fully connected.

[0003] In the existing technical means, a flip cover shell is set on the base, the memory card is fixed on the base through the flip cover shell, and the card is directly placed in the card slot on the base to initially stabilize the card on the base. Due to the influence of the contact height, the card is easy to fall out of the card slot during the closing process, resulting in unsmooth closing.

[0004] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content

[0006] The above technical purpose of the present application is achieved through the following technical solutions: a card holder with an anti-falling structure, comprising a base, a fixing part is provided on the base, and a terminal is provided on the fixing part; a flip cover shell is rotatably provided on the base, and the flip cover shell is surrounded by a mounting groove for accommodating the installation of a card, and one or more first positioning members are provided on the flip cover shell to limit the card on the flip cover shell, and by flipping the flip cover shell, the card is driven to abut or separate from the terminal, and the base can cooperate with the flip cover shell to fix it.

[0007] By adopting the above technical solution, the card is installed into the installation slot, and the card is correctly fixed in the installation slot through the cooperation of the flip cover shell and the first positioning member, which improves the accuracy and stability of the abutment between the card and the terminal; when installing the card or removing the card separation base, the possibility of the card falling off due to external vibration or accidental movement is reduced; when the flip cover shell carries the card and installs it in the base overshoot, the smoothness of closing the cover is improved, and the user experience is improved. When the card abuts the terminal, the base can clamp and fix the flip cover shell, improving the connection stability and reliability between the base and the card.

[0008] Optionally, the base is surrounded to form a card receiving slot, the terminal is arranged in the card receiving slot, and the flip cover shell can be assembled into the card receiving slot.

[0009] By adopting the above technical solution, the card slot formed by the base and the terminal arranged therein can effectively protect and fix the card, ensure the stability of the card in the base, and reduce the possibility of card displacement or damage caused by external vibration or impact. The flip cover shell can be installed in the card slot. When installing or replacing the card, the user can directly place the flip cover shell in the card slot without worrying about the correct docking of the card and the terminal, which simplifies the operation process and reduces the risk of misoperation. The card and flip cover shell can be arranged in the card slot, which can effectively prevent dust, debris and moisture from entering the card slot, reduce the risk of damage to the card and the flip cover shell, and improve the overall protection, ease of use and durability of the card holder.

[0010] Optionally, a through hole is provided on the wall of the card slot, a rotating shaft is provided on the flip cover shell, the rotating shaft passes through the through hole, and a first clamping piece is provided at one end of the rotating shaft away from the flip cover shell; a sliding groove is provided in the through hole to limit the relative rotation of the rotating shaft in the sliding groove.

[0011] By adopting the above technical solution, the flip cover shell is provided with a through hole through the rotating shaft, and the flip cover shell and the first clamping member cooperate to limit the rotating shaft to penetrate the separation through hole, so that the flip cover shell is rotatably set on the base and can rotate relative to the base; the card is installed on the flip cover shell, and the card and the terminal are fully abutted by rotation, and the rotating shaft is rotated to a preset angle so that the rotating shaft can slide in the sliding groove, and the sliding groove is used to limit the relative rotation of the rotating shaft in the sliding groove, so that the flip cover shell is clamped and fixed on the base, ensuring that the card and the terminal are fully abutted, and improving the connection stability and reliability between the base and the card. When the rotating shaft passes through the sliding groove and enters the through hole, the flip cover can be flipped to carry the card to separate the terminal, which is convenient for the installation or removal and replacement of the card.

[0014] Optionally, a second clamping piece is provided on the extension limiter, and the first clamping piece and the second clamping piece are engaged with each other.

[0015] By adopting the above technical solution, the first clamping part and the second clamping part are engaged with each other to limit the sliding of the rotating shaft in the sliding groove, thereby preventing the rotating shaft from moving to the through hole due to accidental touch, causing the flip shell to rotate easily, reducing the possibility of poor contact between the card and the terminal, or even separation and disconnection, and improving the stability between the base and the card.

[0016] Optionally, a third clamping member is provided on the inner wall of the card receiving slot, and a fourth clamping member is provided on the flip cover shell, and the third clamping member and the fourth clamping member are engaged with each other.

[0017] By adopting the above technical solution, by providing a third snap-in component on the inner wall of the card slot and a fourth snap-in component on the flip cover shell, and making them engage with each other, the fixation of the card in the base can be strengthened, ensuring that the card is firmly fixed in the installation slot, and reducing the possibility of card displacement or falling off due to external vibration or impact.

[0018] Optionally, the flip cover housing is provided with a second positioning member near the rotating shaft.

[0019] By adopting the above technical solution, the second positioning member can help the card to follow the flip cover shell to maintain smooth movement when the flip cover shell is opened and closed. It can effectively guide and limit the movement trajectory of the card, reducing the risk of jamming or card damage caused by inaccurate alignment. The second positioning member and the first positioning member can cooperate to stably set the card in the installation slot and stabilize the setting between the card and the flip cover shell.

[0020] Optionally, a switch pin is provided on the base.

[0021] By adopting the above technical solution, the switch pin can be used to detect whether the card has been inserted into the base. When the card is inserted, the pin state changes, triggering the corresponding operation. Similarly, the switch pin can also be used to detect whether the card has been pulled out. When the card is pulled out, the pin state changes again, triggering the corresponding operation. By detecting the insertion status of the card, the switch pin can trigger the operation of starting the power supply or related equipment to start normal operation.

[0022] In summary, this application has at least the following beneficial effects:

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] In this embodiment, refer to Figure 1 A card holder with an anti-drop structure comprises a base 1, preferably the base 1 is a metal fixing frame, a fixing part 2 is arranged on the base 1, the fixing part 2 is an insulating material for the shell, such as plastic, etc., which plays a role in protecting electronic components, and a metal conductor terminal 3 is arranged on the fixing part 2. A flip shell 4 is rotatably arranged on one side of the base 1, and the flip shell 4 is surrounded to form a mounting groove 5, which is used to accommodate a card 6 such as a Micro SD card installed on the flip shell 4. One or more first positioning members 7 are provided on the flip shell 4, preferably two first positioning members 7 are provided, and the two first positioning members 7 are respectively arranged on opposite sides of the flip shell 4. When the flip shell 4 drives the card 6 to fully abut the terminal 3, the base 1 can cooperate with the flip shell 4 to fix the flip shell 4, so that the card 6 and the terminal 3 are stably connected.

[0034] Reference Figure 2-3 When the base 1 and the flip cover housing 4 form a certain preset angle, the user can install the card 6 on the flip cover housing 4 through the installation slot 5, and calibrate the position of the card 6 through the first positioning member 7. After the installation is completed, the user flips the flip cover housing 4, and the first positioning member 7 is limited during the flipping process, so that the card 6 is stably set on the flip cover housing 4, and the card 6 can run synchronously with the flip cover housing 4. During the closing process, the stable setting of the card 6 during the flipping process is ensured, and the process and user experience of closing the cover are improved. At the same time, after closing the cover, the card 6 can accurately and stably abut against the terminal 3, and finally the flip cover housing 4 is fixed by the base 1, so that the installed card 6 will not be separated from the base 1, and the card 6 and the terminal 3 are kept in stable abutment.

[0035] In this embodiment, refer to Figure 2-3 The base 1 is surrounded by a card slot 8, the fixing member 2 and the terminal 3 are arranged in the card slot 8, and the flip cover housing 4 can be installed in the card slot 8 when the cover is closed. The card slot 8 formed by the base 1 and the terminal 3 are arranged therein, which can effectively protect and fix the card 6, ensure the stability of the card 6 in the base 1, and reduce the possibility of displacement or damage of the card 6 caused by external vibration or impact. The flip cover housing 4 can be installed in the card slot 8. When installing or replacing the card 6, the user can directly place the flip cover housing 4 in the card slot 8 without worrying about the correct docking of the card 6 and the terminal 3, which simplifies the operation process and reduces the risk of misoperation. The card 6 and the flip cover housing 4 can be arranged in the card slot 8, which can effectively prevent dust, debris and moisture from entering the card slot 8, reduce the risk of damage to the card 6 and the flip cover housing 4, and improve the overall protection, ease of use and durability of the card holder.

[0036] In this embodiment, refer to Figure 4-5, a through hole 9 is provided on the wall of the card slot 8, a rotating shaft 10 is provided on the flip cover housing 4, the rotating shaft 10 passes through multiple through holes 9, and a first clamping member 11 is provided at one end of the rotating shaft 10 away from the flip cover housing 4, so that the flip cover housing 4 can be rotatably mounted on the base 1. A sliding groove 12 is hollowly provided on the wall of the card slot 8, and one end of the sliding groove 12 is connected to the through hole 9. When the flip cover housing 4 rotates relative to the base 1, the rotating shaft 10 rotates in the through hole 9; when the flip cover housing 4 is fully embedded in the card slot 8, that is, the rotating shaft 10 reaches a preset rotation angle in the through hole 9, the rotating shaft 10 can pass through the sliding groove 12 and slide along the sliding groove 12, and when the flip cover housing 4 is not fully embedded in the card slot 8, the rotating shaft 10 is limited and cannot enter the sliding groove 12 from the through hole 9. When the user has installed the card 6 and embedded the flip cover shell 4 into the card receiving slot 8, the user uses the friction between the finger and the flip cover shell 4 to drive the flip cover shell 4 to slide in the direction of the sliding groove 12 relative to the base 1, and the rotating shaft 10 enters the sliding groove 12, locking the flip cover shell 4 so that the flip cover shell 4 cannot be flipped relative to the base 1.

[0037] In this embodiment, refer to Figure 4 An extension limiter 13 is provided on the base 1 near the through hole 9. The extension limiter 13 is preferably a metal U-shaped elastic arm, which is more fragile than the traditional material which is generally plastic. The extension limiter adopts the function of metal, has the properties of spring sheet and wear resistance. An avoidance groove 14 is formed between the extension limiter 13 and the base 1. When the rotating shaft 10 rotates relative to the through hole 9 or slides in the sliding groove 12, the extension limiter 13 is prevented from touching the first clamping member 11, thereby affecting the movement of the rotating shaft 10. The extension limiter 13 can protect the rotating shaft 10 and the first clamping member 11 from sliding and rotating within the set structure, thereby improving the installation stability of the base 1 and the flip cover shell 4. A second clamping member 15 is provided on the extension limiter 13, and the first clamping member 11 and the second clamping member 15 can be engaged with each other. Preferably, the second clamping member 15 is a protrusion on the metal U-shaped elastic arm. When the user drives the flip cover housing 4 to slide relative to the base 1 in the direction of the sliding groove 12 through the friction between the finger and the flip cover housing 4, the rotating shaft 10 enters the sliding groove 12. When the rotating shaft 10 slides to a certain position, the first clamping member 11 and the second clamping member 15 cooperate to clamp, restricting the rotating shaft 10 from continuing to slide in the sliding groove 12, so that the flip cover can be stably set on the base 1. When it is necessary to flip the flip cover housing 4, the user can push the flip cover housing 4 to move in the direction of the through hole 9 with a greater force, so that the rotating shaft 10 slides in the sliding groove 12 again. After the rotating shaft 10 slides into the through hole 9, the flip cover housing 4 can be flipped relative to the base 1, which is convenient for the user to disassemble and replace the card 6.

[0038] In this embodiment, refer to Figure 2 and Figure 5A third clamping member 16 is provided on the inner wall of the card receiving slot 8, and a fourth clamping member 17 is provided on the flip cover housing 4. The third clamping member 16 and the fourth clamping member 17 are engaged with each other. When the first clamping member 11 and the second clamping member 15 are engaged with each other, the third clamping member 16 and the fourth clamping member 17 are engaged with each other synchronously, thereby improving the installation stability between the flip cover housing 4 and the base 1.

[0039] In this embodiment, refer to Figure 1 A second positioning member 18 is provided near the rotating shaft 10 of the flip cover housing 4. The second positioning member 18 cooperates with the first positioning member 7 to determine the position of the card 6 installed in the installation groove 5. At the same time, when the flip cover housing 4 is flipped, the position of the card 6 is fully stabilized, so that the card 6 can synchronously follow the movement of the flip cover housing 4, determine the precise abutment between the card 6 and the terminal 3, and improve the smoothness of closing the cover.

[0040] In this embodiment, refer to Figure 1 A switch pin 19 is provided on the base 1. When the card 6 abuts against or separates from the terminal 3, the card 6 simultaneously abuts against or separates from the switch pin 19. The insertion status of the card 6 can be detected by the switch pin 19. The switch pin 19 can trigger the operation of starting the power supply or related equipment to start normal operation.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
