Abstract

This application relates to the field of electronic device accessories technology, providing a SIM card fixing mechanism and a terminal device. The SIM card fixing mechanism includes a base and a limiting member. The base is used to install and fix the SIM card and has a card slot for accommodating the SIM card. The limiting member is flexible and includes an abutment portion protruding into the card slot. The abutment portion provides a resisting force to the SIM card, so that the SIM card is stably accommodated in the card slot. During installation, one end of the SIM card first abuts against the abutment portion, and then the other end is pressed into the wall of the card slot. Compared with traditional SIM card holders, by reducing the thickness of the elastic clearance groove required for the elastic structure, the overall length of the SIM card fixing mechanism of this application is shorter in its own length direction, that is, in the direction of insertion into the terminal device.

Description

Technical Field

[0001] This application relates to the field of electronic device accessories technology, and in particular to a SIM card fixing mechanism and a terminal device having the SIM card fixing mechanism. Background Technology

[0002] SIM card is short for Subscribe Identity Module, also known as a smart card or user identification card. A SIM card is installed inside a terminal device via a SIM card holder to connect to a communication network.

[0003] Traditional SIM card holders consist of a base and an elastic structure within it. This elastic structure applies force to the SIM card, confining it within the slot of the base. However, this elastic structure requires a recessed space for flexible clearance, and for waterproofing, a waterproof sealing rib is added to the base. Furthermore, a retaining rib is placed between the elastic structure and the waterproof sealing rib. As a result, the widths of these structures and the slots accumulate along the length of the base, ultimately leading to a relatively long SIM card holder. This makes it difficult to accommodate the limited space available for SIM cards in terminal devices, posing new challenges to the waterproofing and sealing of these devices. Summary of the Invention

[0004] This application provides a SIM card fixing mechanism and terminal device, which can improve the technical problem that the long overall length of the SIM card holder increases the difficulty of waterproof sealing technology for the terminal device.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, this application provides a SIM card fixing mechanism, including a base and a limiting member. The base is used to install and fix the SIM card and has a card slot for accommodating the SIM card. The limiting member is flexible, for example, the limiting member can be made of silicone or rubber. Therefore, the limiting member is disposed on the base and can be fixed on the base by injection molding. The limiting member includes an abutting portion protruding toward the card slot. The abutting portion is used to provide a resisting force to the SIM card, so that the SIM card is stably accommodated in the card slot. Specifically, during the installation process, one end of the SIM card first abuts against the abutting portion, and then the other end is pressed into the wall of the card slot.

[0007] The technical solutions described in this application have at least the following technical effects or advantages:

[0008] The SIM card fixing mechanism provided in this application embodiment has a limiting member on the base body, and the abutting part of the limiting member extends into the card slot to provide abutting force for the SIM card to be accommodated in the card slot. Compared with the traditional SIM card holder, it reduces the thickness of the elastic clearance groove required by the elastic structure. In its own length direction, that is, in the direction of insertion into the terminal device, the overall length of the SIM card fixing mechanism of this application is shorter, which is more suitable for the situation where the space for accommodating the SIM card is limited in the terminal device, and can reduce the technical difficulty of waterproof sealing of the terminal device to a certain extent.

[0009] In some embodiments of the first aspect, the seat includes a main body, a push-top, and an intermediate portion connecting the main body and the push-top. The main body has the slot, and the sidewall of the main body is recessed toward the intermediate portion to form a mounting groove communicating with the slot. The limiting member is disposed in the mounting groove.

[0010] The main body is primarily used to accommodate the SIM card; therefore, the card slot is located on the main body. The push-top is the support for the user's hand and also matches the slot opening of the terminal device, sealing the slot opening. The middle section is a transition section connecting the main body and the push-top. The middle section abuts against the slot wall of the terminal device to meet waterproof and dustproof requirements. A mounting groove is formed on the side wall of the main body to fix a limiting member within the mounting groove. Here, the limiting member can be installed in the mounting groove through in-mold injection molding.

[0011] In some embodiments of the first aspect, the limiting member includes a limiting body disposed in the mounting groove, the limiting body having a first surface facing the slot, and the abutting portion disposed on the first surface.

[0012] The limiting body is the main part of the limiting member housed in the mounting groove. The first surface of the limiting body corresponds to the side wall of the main body near the middle part. The abutting part is provided on the first surface. Then, a part of the side wall of the SIM card abuts against the abutting part, and another part of the side wall abuts against the side wall of the main body.

[0013] In some embodiments of the first aspect, the first surface is flush with the corresponding sidewall of the main body portion.

[0014] Understandably, only the abutting part protrudes into the slot, and the first surface and the corresponding sidewall of the main body together form the sidewall of the slot.

[0015] In some embodiments of the first aspect, the thickness of the abutment portion towards the first surface gradually decreases in the thickness direction of the seat.

[0016] Understandably, the thickness of the abutment portion is uneven in the thickness direction of the base body, presenting a structure that is larger at one end and smaller at the other. Thus, the force exerted on the SIM card at the abutment portion is mainly provided by the thicker abutment portion, thereby improving the installation stability of the SIM card in the card slot.

[0017] In some embodiments of the first aspect, the limiting body has a second surface that is angled to the first surface, and the abutting portion has a top end portion and a bottom end portion, the surface of the top end portion being flush with the second surface and both being lower than the end face of the body portion.

[0018] The second surface can be a surface facing the same direction as the card slot opening. The top end of the abutment portion is close to the second surface, and the bottom end of the abutment portion is away from the second surface. The surface of the top end is flush with the second surface and both are lower than the end face of the main body, so that the top end and the limiting body interfere with each other in the thickness direction of the main body. In this way, the SIM card fixing mechanism can be inserted into the slot of the terminal device more smoothly.

[0019] In some embodiments of the first aspect, the SIM card fixing mechanism further includes a partition plate that divides the card slot into a first sub-card slot and a second sub-card slot. The first sub-card slot and the second sub-card slot are each provided with a limiting member, and the abutting portion of each limiting member extends into the corresponding sub-card slot.

[0020] After the partition plate is added, the SIM card fixing mechanism can accommodate two SIM cards at the same time, and they are respectively set in the first sub-card slot and the second sub-card slot. Furthermore, corresponding limiting members are set in both sub-card slots, and their abutting parts extend into the corresponding sub-card slots to satisfy the function of limiting the SIM cards.

[0021] In some embodiments of the first aspect, the mounting slot includes a first sub-mounting slot communicating with the first sub-slot and a second sub-mounting slot communicating with the second sub-slot. The first sub-mounting slot and the second sub-mounting slot are connected in the thickness direction of the base body, and the first sub-mounting slot and the second sub-mounting slot are staggered.

[0022] To accommodate the installation of the two limiting components, the mounting slot is divided into two sub-mounting slots by a partition plate, each designed to hold a corresponding limiting component. Since the first and second sub-mounting slots are connected, the two limiting components can be formed within their respective sub-mounting slots through a single in-mold injection molding process. Furthermore, the interconnectedness of the two sub-mounting slots creates a connection between the two limiting components. Additionally, the staggered arrangement of the two sub-mounting slots ensures that the bottom wall of one sub-mounting slot extends into the space of the other. This provides support for the limiting components along the thickness of the base, further enhancing their installation stability within the mounting slot.

[0023] In some embodiments of the first aspect, at least a portion of the partition plate extends into the first sub-mounting slot and the second sub-mounting slot, and the partition plate is spaced apart from the slot sidewall of the first sub-mounting slot or the slot sidewall of the second sub-mounting slot.

[0024] Understandably, the partition plate also provides a certain supporting force to the limiting member in the thickness direction of the seat. At the same time, the partition plate does not separate the two limiting members. Therefore, the structural strength of the two limiting members that are combined together is higher.

[0025] In some embodiments of the first aspect, the surface of the top end of the abutment portion is recessed to form a groove; and / or, the second surface of the limiting body is recessed to form a groove.

[0026] The grooves formed on the top surface and / or the second surface can provide greater deformation space against the top.

[0027] In some embodiments of the first aspect, the limiting member further includes a sealing portion, wherein an annular groove structure is formed on the intermediate portion, and the sealing portion is disposed at the annular groove structure.

[0028] The sealing part is formed in the annular groove structure in the middle part to improve the sealing performance at the connection between the SIM card fixing mechanism and the terminal device.

[0029] In some embodiments of the first aspect, the sealing portion is integrally formed with the limiting body.

[0030] Understandably, the sealing part and the limiting body are integrally molded onto the base body by in-mold injection molding, which further saves space and thickness.

[0031] Secondly, this application provides a terminal device, including a device body and the aforementioned SIM card fixing mechanism. The device body has a slot, and the SIM card fixing mechanism is inserted into the slot.

[0032] The technical solutions described in this application have at least the following technical effects or advantages:

[0033] The terminal device provided in this application embodiment, based on the above-mentioned SIM card fixing mechanism, has a slot depth on the main body of the device that can be set to be smaller, which is more conducive to the waterproof and dustproof design of the terminal device.

Specifically, the use of the words "in some embodiments," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner.

[0061] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0062] like Figure 1As shown, a traditional SIM card holder 1 provides an elastic structure 2 within the card slot to limit the SIM card's position. This elastic structure 2 needs to form an elastic clearance groove 3 with the inner wall of the card slot to allow for deformation of the elastic structure 2. Simultaneously, to improve the waterproof and dustproof performance of the SIM card holder, a sealing rib 4 is also provided. Furthermore, a baffle rib 5 is provided between the sealing rib 4 and the elastic clearance groove 3 to block the sealing rib 4. This results in a longer SIM card holder, requiring a larger internal space in the terminal device, which increases the difficulty of achieving waterproof and dustproof performance for the terminal device.

[0063] Typically, the thickness a of the elastic structure 2 is greater than or equal to 0.4 mm, the width b of the elastic clearance groove 3 is greater than or equal to 0.5 mm, the waterproof sealing rib uses an O-ring silicone ring, the width d of the sealing rib 4 is greater than or equal to 1 mm, and the width c of the baffle rib 5 is greater than or equal to 0.4 mm. Therefore, with the same SIM card size, the SIM card holder needs to be increased by at least 2.3 mm.

[0064] In view of this, this application provides a SIM card fixing mechanism with a limiting member on the base. The abutting portion of the limiting member extends into the card slot to abut the SIM card in the card slot, so that the SIM card is stably accommodated in the card slot. Compared with traditional SIM card holders, by reducing the thickness of the elastic clearance groove required for the elastic structure, the overall length of the SIM card fixing mechanism of this application is shorter in its own length direction, that is, in the direction of insertion into the terminal device. It is more suitable for situations where the space for accommodating the SIM card is limited in the terminal device, and can reduce the technical difficulty of waterproof sealing of the terminal device to a certain extent.

[0065] The terminal device provided in this application belongs to the category of foldable electronic devices, that is, electronic devices that can be folded and unfolded. For example, the terminal device can be a mobile phone, tablet computer, laptop computer, notebook PC, personal digital assistant (PDA), wearable device (e.g., watch), in-vehicle device, augmented reality (AR) / virtual reality (VR) device, point of sale (POS) terminal, dashcam, walkie-talkie, camera, monitor, etc., but is not limited to these.

[0066] Please see Figure 2 , Figure 2 This paper presents a three-dimensional structural diagram of a terminal device in its unfolded state according to some embodiments of this application, with the terminal device 1000 being a mobile phone as an example for description.

[0067] This application provides a terminal device 1000, including a device body 1001 and a SIM card fixing mechanism 100. The device body 1001 has a slot 1002, and the SIM card fixing mechanism 100 is inserted into the slot 1002.

[0068] The device body 1001 refers to the part of the terminal device that can realize information input and output. The device body 1001 includes a shell, a control panel located inside the shell, and a display screen electrically connected to the control panel. The slot 1002 is used for inserting the SIM card fixing mechanism 100. After the SIM card fixing mechanism 100 is inserted, the SIM card is electrically connected to the control panel inside the device body 1001, thereby enabling the terminal device to access the corresponding communication network.

[0069] The SIM card fixing mechanism 100 is used to install and fix the SIM card.

[0070] The SIM card fixing mechanism 100 of this application has a shorter overall length, which allows the slot 1002 that is adapted to it to be designed to be shorter, saving some of the internal space of the main body 1001 of the device, and thus reducing the design difficulty of waterproofing and dustproofing the terminal device at the slot 1002.

[0071] The technical solutions described in this application have at least the following technical effects or advantages:

[0072] The terminal device provided in this application embodiment, based on the SIM card fixing mechanism 100 described above, has a smaller depth in the slot 1002 on the main body 1001 of the device, which is more conducive to the waterproof and dustproof design of the terminal device.

[0073] Please refer to Figure 3 and Figure 4 This application discloses a SIM card fixing mechanism 100, including a base 10 and a limiting member 20. The base 10 is used to install and fix a SIM card 1003, and the base 10 has a card slot 10a for accommodating the SIM card 1003; the slot shape of the card slot 10a is adapted to the outer shape of the SIM card 1003. Typically, the SIM card 1003 has a square structure, so the card slot 10a is also a square card slot 10a, which has four slot sidewalls adapted to the SIM card 1003.

[0074] The limiting member 20 is flexible. For example, the limiting member 20 can be made of silicone or rubber. Therefore, the limiting member 20 is disposed on the base 10, for example, it can be fixed on the base 10 by injection molding. The limiting member 20 includes an abutting part 21 protruding toward the card slot 10a. The abutting part 21 is used to provide a resisting force to the SIM card 1003, so that the SIM card 1003 is stably accommodated in the card slot 10a.

[0075] Specifically, during the installation process, one end of the SIM card 1003 first abuts against the abutment part 21, and then the other end is pressed into the groove wall of the card slot 10a.

[0076] The technical solutions described in this application have at least the following technical effects or advantages:

[0077] The SIM card fixing mechanism 100 provided in this application embodiment has a limiting member 20 on the base 10, and the abutting part 21 of the limiting member 20 extends into the card slot 10a, providing abutting force for the SIM card 1003 to be accommodated in the card slot 10a. Compared with the traditional SIM card 1003 card holder, the thickness corresponding to the elastic clearance groove required by the elastic structure is reduced. In its own length direction, that is, in the direction of insertion into the terminal device, the overall length of the SIM card fixing mechanism 100 of this application is shorter, which is more suitable for the situation where the space for accommodating the SIM card 1003 in the terminal device is limited, and can reduce the technical difficulty of waterproof sealing of the terminal device to a certain extent.

[0078] Please refer to Figure 3 and Figure 10 In some embodiments, the seat 10 includes a main body 11, a push top 12, and a middle part 13 connecting the main body 11 and the push top 12. The main body 11 has a slot 10a, and the side wall of the main body 11 is recessed toward the middle part 13 to form a mounting groove 10b that communicates with the slot 10a. The limiting member 20 is disposed in the mounting groove 10b.

[0079] The main body 11 is mainly used to accommodate the SIM card 1003, and the card slot 10a is provided on the main body 11; the push top 12 is a support part for the user's hand, and at the same time, the push top 12 matches the slot 1002 of the terminal device and can block the slot 1002; the middle part 13 is a transition part used to connect the main body 11 and the push top 12, and at the same time, the middle part 13 abuts against the slot wall of the slot 1002 of the terminal device to meet the requirements of waterproof and dustproof.

[0080] A mounting groove 10b is formed on the side wall of the main body 11. Specifically, the mounting groove 10b is set on the side wall of the main body 11 near the middle part 13. The limiting member 20 is fixed in the mounting groove 10b to improve the connection stability of the limiting member 20 on the seat 10. Here, the limiting member 20 can be set in the mounting groove 10b by in-mold injection molding.

[0081] Please refer to Figure 3 and Figure 4In some embodiments, the limiting member 20 includes a limiting body 22 disposed in the mounting groove 10b, the limiting body 22 having a first surface 22a facing the slot 10a, and an abutment portion 21 disposed on the first surface 22a.

[0082] The limiting body 22 is the main part of the limiting member 20 that is housed within the mounting groove 10b. The first surface 22a of the limiting body 22 corresponds to the side wall of the main body 11 near the middle portion 13. Understandably, the first surface 22a of the limiting body 22 is used to compensate for the absence of the side wall caused by the opening of the mounting groove 10b; that is, the first surface 22a of the limiting body 22 and the side wall of the main body 11 together enclose and form the slot 10a.

[0083] The abutment portion 21 is provided on the first surface 22a, so that the abutment portion 21 faces the side wall of the SIM card 1003. When the SIM card 1003 is fixed in the card slot 10a, a part of the side wall of the SIM card 1003 abuts against the abutment portion 21, and another part of the side wall abuts against the side wall of the main body portion 11.

[0084] Here, the first surface 22a and the side wall of the current main body 11 can have three positional relationships: the first surface 22a protrudes from the side wall of the main body 11; the first surface 22a is flush with the side wall of the main body 11; and the first surface 22a is recessed into the side wall of the main body 11.

[0085] Compared to the first surface 22a being flush with the side wall of the main body 11, in the other two cases, the size of the abutment part 21 needs to be adjusted to meet the abutment requirements of the SIM card 1003 in different scenarios.

[0086] Please refer to Figure 4 In some embodiments, the first surface 22a is flush with the corresponding sidewall of the main body 11.

[0087] Understandably, only the abutting part 21 protrudes into the slot 10a, and the first surface 22a and the corresponding side wall of the main body part 11 together form the side wall of the slot 10a.

[0088] Please refer to Figures 6 to 8 In some embodiments, the thickness of the abutment portion 21 to the first surface 22a gradually decreases in the thickness direction of the seat 10.

[0089] For ease of understanding, the thickness direction of the base 10 is the Z direction in the figure.

[0090] Understandably, the thickness of the abutment portion 21 in the thickness direction of the seat body 10 is not uniform. Here, the thickness of the abutment portion 21 refers to the distance from the end of the abutment portion 21 away from the first surface 22a to the first surface 22a.

[0091] That is, in the Z direction, the abutment portion 21 has a structure that is larger at one end and smaller at the other end. In this way, the force on the SIM card 1003 at the abutment portion 21 is mainly provided by the thicker abutment portion 21, thereby improving the installation stability of the SIM card 1003 in the card slot 10a.

[0092] Alternatively, it can be understood that the side of the contact portion 21 away from the first surface 22a has an inclined surface. When it comes into contact with the SIM card 1003, the inclined surface of the contact portion 21 comes into contact with the side wall of the SIM card 1003. The plane of the inclined surface forms an acute angle with the plane of the first surface 22a.

[0093] Here, the variation trend of the thickness of the contact portion 21 to the first surface 22a can be adjusted according to the actual contact requirements of the SIM card 1003. For example, the thickness of the contact portion 21 may have a linear gradual change trend, or the variation trend of the thickness of the contact portion 21 may start relatively gently and then gradually change linearly. That is, the slope of the inclined surface of the contact portion 21 may remain unchanged, or the slope of the inclined surface of the contact portion 21 may change first and then remain unchanged.

[0094] Thus, the abutment force exerted by the abutment portion 21 with varying thickness on the sidewall of the SIM card 1003 is directly proportional to its thickness; that is, the thicker the abutment portion 21, the greater the abutment force on the sidewall of the SIM card 1003. Therefore, the entire abutment portion 21 exerts a force on the sidewall of the SIM card 1003 at an angle to the horizontal direction. When this abutment force is directed towards the inner wall of the bottom of the card slot 10a, the installation stability of the SIM card 1003 within the card slot 10a is even higher.

[0095] Please refer to Figure 4 In some embodiments, the limiting body 22 has a second surface 22b that is angled to the first surface 22a, and the abutting portion 21 has a top end portion 21a and a bottom end portion 21b. The surface of the top end portion 21a is flush with the second surface 22b and both are lower than the end face of the body portion 11.

[0096] The second surface 22b faces the same direction as the opening of the card slot 10a. The top end 21a of the abutment portion 21 is close to the second surface 22b, and the bottom end 21b of the abutment portion 21 is away from the second surface 22b. Thus, the top end 21a of the abutment portion 21 is close to the opening of the card slot 10a, and the bottom end 21b of the abutment portion 21 is close to the bottom of the slot. In this way, the entire abutment portion 21 applies a horizontal downward force to the side wall of the SIM card 1003. That is, the abutting force is directed towards the inner wall of the bottom of the card slot 10a. At this time, the installation stability of the SIM card 1003 in the card slot 10a is higher.

[0097] The surface of the top part 21a is flush with the second surface 22b and both are lower than the end face of the main body 11, so that the top part and the limiting body 22 interfere with each other in the thickness direction of the main body 11. In this way, the SIM card fixing mechanism 100 can be inserted into the slot 1002 of the terminal device more smoothly.

[0098] Please refer to Figure 3 and Figure 7 In some embodiments, the SIM card fixing mechanism 100 further includes a partition plate 30, which divides the card slot 10a into a first sub-card slot 10a1 and a second sub-card slot 10a2. Each of the first sub-card slot 10a1 and the second sub-card slot 10a2 is provided with a limiting member 20, and the abutting portion 21 of each limiting member 20 extends into the corresponding sub-card slot 10a.

[0099] Understandably, after the partition plate 30 is added, the SIM card fixing mechanism 100 can simultaneously accommodate two SIM cards 1003, and the SIM cards 1003 are respectively disposed in the first sub-card slot 10a1 and the second sub-card slot 10a2. Furthermore, corresponding limiting members 20 are provided in both sub-card slots 10a, and their abutting parts 21 extend into the corresponding sub-card slots 10a to satisfy the function of limiting the SIM cards 1003.

[0100] Please refer to Figure 10 In some embodiments, the mounting groove 10b includes a first sub-mounting groove 10b1 connected to the first sub-slot 10a1 and a second sub-mounting groove 10b2 connected to the second sub-slot 10a2. The first sub-mounting groove 10b1 and the second sub-mounting groove 10b2 are connected in the thickness direction of the base body 10, and the two are staggered.

[0101] To accommodate the installation of the two limiting members 20, the mounting groove 10b is divided by the partition plate 30 into two sub-mounting grooves 10b for housing the corresponding limiting members 20. Since the first sub-mounting groove 10b1 and the second sub-mounting groove 10b2 are connected, the two limiting members 20 can be formed in the corresponding sub-mounting grooves 10b through a single in-mold injection molding process. Simultaneously, the two sub-mounting grooves 10b are connected, creating a certain connection between the two limiting members 20. For example, the two limiting members 20 can be formed in the corresponding sub-mounting grooves 10b through a single in-mold injection molding process. Because the two sub-mounting grooves 10b are connected, the two limiting members 20 are a single-piece molded structure.

[0102] Furthermore, the two sub-mounting slots 10b are staggered. Understandably, in the thickness direction of the base 10, the inner walls of the two sub-mounting slots 10b are not completely aligned, meaning their projections partially overlap. Thus, the bottom wall of one sub-mounting slot 10b must extend into the space of the other sub-mounting slot 10b. This provides a certain supporting force to the limiting member 20 in the thickness direction of the base 10, further improving the installation stability of the limiting member 20 within the mounting slot 10b.

[0103] Please refer to Figure 11 In some embodiments, at least a portion of the partition plate 30 extends into the first sub-mounting groove 10b1 and the second sub-mounting groove 10b2, and the partition plate 30 does not abut against the groove sidewall of the first sub-mounting groove 10b1 or the groove sidewall of the second sub-mounting groove 10b2.

[0104] Understandably, in the thickness direction of the base 10, the projection of the partition plate 30 and the projection of the sub-mounting groove 10b partially overlap. The partition plate 30 extending into the sub-mounting groove 10b also provides a certain supporting force to the limiting member 20. At the same time, the partition plate 30 does not separate the two limiting members 20. The two limiting members 20 are still connected. Thus, the structural strength of the two limiting members 20 combined together is higher.

[0105] Please refer to Figure 5 In some embodiments, the surface of the top end portion 21a of the abutment portion 21 is recessed to form a groove 20a; and / or, the second surface 22b of the limiting body 22 is recessed to form a groove 20a.

[0106] Understandably, the groove 20a may be formed on the second surface 22b of the limiting body 22, or the groove 20a may be formed on the surface of the top end portion 21a of the abutment portion 21; or the groove 20a may be formed on the surfaces of the second surface 22b of the limiting body 22 and the top end portion 21a of the abutment portion 21.

[0107] Here, the groove 20a is used to increase the degree of deformation of the abutting part 21 after it is abutted. That is, after the groove 20a is added, the deformation range of the abutting part 21 is greater than that when the groove 20a is not provided.

[0108] Please refer to Figure 3 In some embodiments, the limiting member 20 further includes a sealing part 23, with an annular groove structure 13a formed on the middle part 13, and the sealing part 23 is disposed at the annular groove structure 13a.

[0109] The sealing part 23 is formed in the annular groove structure 13a of the middle part 13 to improve the sealing performance at the connection between the SIM card fixing mechanism 100 and the terminal device.

[0110] In some embodiments, the sealing part 23 is integrally formed with the limiting body 22.

[0111] Understandably, the sealing part 23 and the limiting body 22 are integrally molded onto the base 10 by in-mold injection molding, which can further save space and thickness.

[0112] Please refer to Figure 12 In some specific embodiments, the width g of the sealing part 23 is greater than or equal to 0.55 mm, the width e of the abutting part 21 is greater than or equal to 0.3 mm, and the width f of the limiting body 22 is greater than or equal to 0.45 mm. Therefore, with the same SIM card size, the SIM card fixing mechanism of this application needs to be increased by at least 1.3 mm. Compared with the traditional SIM card holder 1, the SIM card fixing mechanism provided in this application can save 1.1 mm.

[0113] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
