Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment accessories, and in particular to a card holder with a guide and limit function. Background Art

[0002] In electronic devices, the card holder is a crucial component for installing cards (such as SIM cards and memory cards). With the continuous development of electronic devices, the requirements for card holders are becoming increasingly stringent. Conventional card holders often encounter the following issues when inserting cards: Card insertion is not smooth. Due to the lack of an effective guide structure, the card is prone to shifting or getting stuck during insertion, requiring multiple attempts to successfully insert the card, impacting the user experience. Card positioning is inaccurate, and card holders without a retaining function can easily cause the card to misalign, become loose, or fall out, leading to poor contact or unstable signals, impacting the normal operation of the electronic device.

[0003] Therefore, based on the above problems, the existing technology needs to be improved. Utility Model Content

[0004] The purpose of this application is to effectively improve the accuracy and stability of card installation into the card holder.

[0005] The above technical purpose of the present application is achieved through the following technical solutions: a card holder with a guiding and limiting function, comprising a base, a terminal provided on the base, a shell provided on the base, the base and the shell together form a slot, and a limiting guide is provided on at least one side of the shell for guiding and limiting a card inserted into the slot.

[0006] By adopting the above technical solution, the limiting guide can provide guidance when inserting the card into the slot, allowing the card to be inserted smoothly, reducing card deviation or jamming, and improving the user experience. At the same time, the limiting guide can also limit the card's position, ensuring the card is accurately positioned after insertion, reducing the possibility of card misalignment, loosening, or falling out, and ensuring the normal operation of the electronic device.

[0007] Optionally, the position-limiting guide member includes a deformation portion and a connection portion, the deformation portion is provided with a guide surface, and the connection portion is provided at both ends of the deformation portion.

[0008] By adopting this technical solution, when a card is inserted into the slot, the guide surface on the deformable portion guides the card smoothly into the slot, reducing resistance and jamming during insertion. Furthermore, the deformable portion deforms according to the insertion of the card, better adapting to the size and shape of the card and improving guidance accuracy. The connecting portions, located at both ends of the deformable portion, ensure a stable connection between the deformable portion and the housing, enhancing the overall strength and stability of the position-limiting guide, enabling it to effectively position the card, preventing it from loosening or shifting during use, and ensuring the card's accurate position after insertion.

[0009] Optionally, two position-limiting guide members are provided, and the two position-limiting guide members are relatively arranged on two sides of the shell close to the slot.

[0010] By adopting this technical solution, two opposing position-limiting guides effectively guide and position the card inserted into the slot from both sides. During card insertion, the two opposing position-limiting guides work together to more evenly apply force to the card, further ensuring accurate insertion into the slot and preventing it from shifting or tilting. This opposing arrangement also enhances the card's grip, making it more secure in the slot and less likely to loosen, effectively ensuring the card's positional accuracy and stability after insertion.

[0011] Optionally, a limit stop is provided on the base.

[0012] By adopting the above technical solution, the limit stopper can limit the insertion depth of the card when it is inserted into the slot. When the card is inserted to a certain position, the limit stopper prevents the card from being inserted further, thus preventing damage or poor contact caused by over-insertion. This ensures the card is accurately positioned in the slot, improves the connection stability between the card holder and the card, and ensures the normal operation of the electronic device. The limit stopper also plays a certain positioning role, allowing the card to find the correct position more quickly during insertion, improving the user experience.

[0013] Optionally, a first clamping piece is provided on the base, and a second clamping piece is provided on the shell, and the first clamping piece and the second clamping piece are engaged with each other.

[0014] By adopting the above technical solution, the mating engagement of the first and second clips securely connects the base and housing. This connection ensures that the base and housing will not easily separate during use, thereby maintaining the overall stability of the card holder. Furthermore, the tight connection effectively prevents dust and debris from entering the card holder, protecting the terminals and card, and increasing the reliability and service life of the card holder. Furthermore, the design of the clips facilitates assembly and disassembly of the card holder, improving efficiency and reducing costs during production and maintenance.

[0015] Optionally, a card removal opening is provided on the housing.

[0016] By adopting the above technical solution, the card access opening on the housing provides users with convenient and quick access to their cards. When users need to remove a card, they simply operate through the card access opening, without the need for additional tools or complicated steps, significantly improving card retrieval efficiency. Furthermore, the design of the card access opening prevents damage to the card holder and card during the retrieval process, protecting the integrity of the card holder and the security of the card. Furthermore, the rationally designed card access opening position and size make operation more comfortable and natural, enhancing the user experience.

[0017] Optionally, the housing is provided with a mounting piece near the slot, and the slot and the card inserted into the slot are interference fit.

[0018] By adopting the above technical solution, the mounting member provided near the slot of the housing can enhance the stability and firmness of the card holder during installation. The mounting member can be connected to an external device or structure, ensuring that the card holder can be accurately installed in the predetermined position and is not prone to loosening or displacement.

[0019] The interference fit between the slot and the card inserted into it ensures a tight fit, reducing any loosening or movement during use and further enhancing the stability of the connection between the card and the socket. The interference fit increases the contact pressure between the card and the terminals, ensuring stable and reliable signal transmission.

[0020] Optionally, there are several mounting members.

[0021] By adopting this technical solution, multiple mounting components can secure the card holder from multiple angles and positions. These multiple mounting components can disperse the stress during installation, making the card holder more stable and less likely to loosen or shift. The multiple mounting components can also improve the card holder's shock resistance. When the electronic device is subjected to vibration or impact, the multiple mounting components can share the external force, reducing the impact on the card holder and the cards inside, and protecting the normal operation of the electronic device.

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

[0023] 1. This application can effectively ensure the accurate position of the card after insertion by setting up limit guides, limit blocks, and interference fit between the shell and the card, avoiding card loosening, misalignment, etc., and ensuring the normal operation of the electronic device and the stability of signal transmission.

[0024] 2. The base and housing are securely connected via snap-on connectors. The mounting hardware enhances stability and flexibility, while multiple mounting hardware further improves shock resistance. Furthermore, the card access opening design facilitates card removal, enhancing the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present application is further described in detail below with reference to the accompanying drawings.

[0031] In this embodiment, referring to Figure 1-2 A card holder with guiding and limiting functions comprises a base 1, terminals 2, and a housing 3. The base 1 and housing 3 form a slot 4, and a limiting guide 5 is provided on at least one side of the housing 3 to guide and limit the position of a card inserted into the slot 4. This provides the basic structure of the card holder, ensuring that the card is guided and positioned during insertion, improving insertion accuracy and stability.

[0032] Reference Figure 3 The position-limiting guide 5 includes a deformable portion 51 and a connecting portion 52. The deformable portion 51 has a guide surface 53, and the connecting portions 52 are located at both ends of the deformable portion 51. This design ensures that when a card is inserted, the guide surface 53 guides the card smoothly into the slot, the deformable portion 51 can deform to better adapt to the card, and the connecting portion 52 ensures the stability of the overall structure, thereby effectively limiting the card position.

[0033] Reference Figure 3 Preferably, two limiting guides 5 are provided and are relatively arranged on both sides of the housing 3 near the slot 4. This relative arrangement makes the card evenly stressed, further ensuring accurate insertion, while enhancing the clamping force on the card and improving the stability of card installation.

[0034] Reference Figure 2 A limit block 6 is provided on the base 1, which can limit the insertion depth of the card to avoid damage or poor contact caused by excessive insertion. It can also play a positioning role to improve the accuracy of card installation.

[0035] Reference Figure 2 The base 1 is provided with a first clamping member 7, and the housing 3 is provided with a second clamping member 8 at a position corresponding to the first clamping member 7. The housing 3 is mounted on the base 1 through the first clamping member 7 and the second clamping member 8, ensuring a secure connection between the two, improving the overall stability of the base, preventing dust from entering, and facilitating assembly and disassembly.

[0036] Reference Figure 1 A card taking opening 9 is provided on the housing 3, which provides a convenient way for users to take out the card, avoids damage to the card holder and the card when taking out the card, and improves the user experience.

[0037] Reference Figure 2 A mounting part 10 is provided near the slot 4 on the housing 3. There are several mounting parts 10, preferably two mounting parts 10, which are spaced apart. When the card is inserted into the slot 4, the slot 4 and the card have an interference fit, so that the card and the terminal 2 on the base 1 are in full contact, thereby enhancing the installation stability of the card holder and the card, and ensuring stable signal transmission.

[0038] The implementation principle of this embodiment is as follows: When a card is to be inserted into the card holder, the card first contacts the guide surface 53 of the upper limit guide 5 on the shell 3. Under the guidance of the guide surface 53, the card is oriented so that the card can smoothly enter the slot 4. As the card is inserted, the deformation portion 51 will deform appropriately according to the size and shape of the card to better adapt to the card. The connection portion 52 ensures that the deformation portion 51 is stably connected to the shell 3, so that the limit guide 5 can effectively guide and limit the card. The two oppositely arranged limit guides 5 clamp the card from both sides, enhancing the fixing effect on the card, making the card more stable in the slot 4, avoiding misalignment, loosening or falling off, and ensuring the normal operation of the electronic device and the stability of signal transmission. When the card is inserted to a specific position, the limit block 6 on the base 1 will prevent the card from going deeper, ensuring the accurate insertion depth of the card and improving the connection stability between the card holder and the card. By providing several mounting members 10 on the housing 3, slot 4 and the inserted card achieve an interference fit, ensuring a tight fit within the slot 4 and reducing any loosening or movement during use. To remove a card, the user accesses the card through a card access opening 9 on the housing 3. The optimal location and size of the card access opening 9 facilitate easy removal of the card from slot 4 without the need for additional tools, while also preventing damage to the card holder and card during removal.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
