Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment accessories, and in particular to a SIM card fixing mechanism and a terminal device having the SIM card fixing mechanism. Background Art

[0002] SIM card is the abbreviation of Subscribe Identity Module, also known as smart card or user identity card. SIM card is installed in the terminal device through the SIM card fixing mechanism to connect to the communication network.

[0003] The traditional SIM card holder structure includes a holder body, an elastic structure in the holder body, and the elastic structure is used to apply force to the SIM card so that the SIM card is limited in the card slot of the holder body. However, the elastic structure also needs to reserve an elastic avoidance groove, and for waterproofing requirements, a waterproof sealing rib is also provided on the holder body, and a retaining rib edge is also provided between the elastic structure and the waterproof sealing rib. In this way, the width of each structure and the width of the groove are accumulated in the length direction of the holder body, which ultimately leads to a long length of the SIM card holder, which is difficult to adapt to the situation where the SIM card accommodation space in the terminal device is short, which puts forward new requirements for the waterproof sealing of the terminal device. Summary of the invention

[0004] The embodiments of the present application provide a SIM card fixing mechanism and a terminal device, which can improve the technical problem that the waterproof sealing technology of the terminal device is more difficult due to the long overall length of the SIM card socket.

[0005] To achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] In a first aspect, the present application provides a SIM card fixing mechanism, comprising a seat body and a limit member, wherein the seat body is used to install and fix the SIM card, and the seat body has a card slot for accommodating the SIM card; the limit member is flexible, for example, the limit member can be made of silicone or rubber, and thus, the limit member is arranged on the seat body and can be fixed on the seat body by injection molding; the limit member comprises an abutment portion protruding toward the card slot; the abutment portion is used to provide a supporting 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 abutment portion, and then the other end thereof is pressed into the slot wall of the card slot.

[0007] The above technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0008] The SIM card fixing mechanism provided in the embodiment of the present application is provided with a limit piece on the seat body, and the abutting portion of the limit piece extends into the card slot to provide an abutting force for the SIM card accommodated in the card slot. Compared with the traditional SIM card seat, the thickness corresponding to the elastic avoidance groove required by the elastic structure is reduced. In its own length direction, that is, the direction of insertion into the terminal device, the overall length of the SIM card fixing mechanism of the present application is shorter, which is more suitable for the situation where the space for accommodating the SIM card in the terminal device is limited, 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 body includes a main body, a push top portion, and a middle portion connected to the main body and the push top portion, the main body is provided with the card slot, the side wall of the main body is recessed toward the middle portion to form an installation groove connected to the card slot, and the limiting member is arranged in the installation groove.

[0010] The main body is mainly used to accommodate the SIM card, so the card slot is set on the main body; the push top is used for the user's hand to exert force, and at the same time, the push top matches the slot of the terminal device and can block the slot; the middle part is a transition part, which is used to connect the main body and the push top, and at the same time, the middle part abuts against the slot wall of the slot of the terminal device to achieve the requirements of waterproof and dustproof. An installation groove is opened on the side wall of the main body, and the limiter is fixed in the installation groove. Here, the limiter can be set in the installation groove by in-mold injection molding.

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

[0012] The limiting body is the main part of the limiting member accommodated in the installation groove. The first surface of the limiting body corresponds to the side wall of the main body close to the middle part. The abutting part is arranged on the first surface. Then, a part of the side wall of the SIM card abuts against the abutting part, and the other 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 a corresponding side wall of the main body.

[0014] It can be understood that only the abutting portion protrudes into the slot, and the first surface and the corresponding side wall of the main body together form the side wall of the slot.

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

[0016] It can be understood that the thickness of the abutment in the thickness direction of the seat body is uneven, presenting a structure in which one end is large and the other end is small. In this way, the force acting on the SIM card at the abutment is mainly provided by the thicker abutment, 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 set at an angle with the first surface, the abutment portion has a top end and a bottom end, the surface of the top end is flush with the second surface, and both are lower than the end surface of the main body.

[0018] The second surface may be a surface facing the same direction as the notch of the card slot, the top end of the abutting portion is close to the second surface, and the bottom end of the abutting 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 surface of the main body, so that the abutting top and the limiting body interfere with each other in the thickness direction of the main body, and then the SIM card fixing mechanism can be more smoothly inserted into the slot of the terminal device.

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

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

[0021] In some embodiments of the first aspect, the mounting groove includes a first sub-mounting groove connected to the first sub-card slot and a second sub-mounting groove connected to the second sub-card slot, and in the thickness direction of the seat body, the first sub-mounting groove and the second sub-mounting groove are connected, and the first sub-mounting groove and the second sub-mounting groove are staggered.

[0022] In order to meet the installation requirements of the two limit members, the installation groove is also divided by a partition plate to form two sub-installation grooves for accommodating the corresponding limit members. Since the first sub-installation groove and the second sub-installation groove are connected, the two limit members can be formed in the corresponding sub-installation grooves by a one-time in-mold injection molding method. At the same time, the two sub-installation grooves are connected, so that the two limit members have a certain connection relationship, and the two sub-installation grooves are staggered, so that the bottom wall of one of the sub-installation grooves must extend into the groove space of the other sub-installation groove, so that a certain supporting force can be provided to the limit member in the thickness direction of the seat body, further improving the installation stability of the limit member in the installation groove.

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

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

[0025] In some embodiments of the first aspect, the surface of the top end portion of the abutting 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 surface of the top end portion and / or the second surface may provide a larger deformation space for the top portion.

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

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

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

[0030] It can be understood that the sealing portion and the limiting body are integrally formed on the seat body by in-mold injection molding, so that the space thickness can be further saved.

[0031] In a second aspect, an embodiment of the present application provides a terminal device, including a device body and the above-mentioned SIM card fixing mechanism, wherein a slot is provided on the device body, and the SIM card fixing mechanism is inserted into the slot.

[0032] The above technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

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

Specifically, the use of words such as "in some embodiments", "exemplarily", "for example", etc. is intended to present related concepts in a specific way.

[0061] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0062] like Figure 1As shown, the conventional SIM card holder 1 provides an elastic structure 2 in the card slot to limit the SIM card, and the elastic structure 2 needs to form an elastic avoidance groove 3 with the inner wall of the card slot to allow the elastic structure 2 to deform. At the same time, in order to improve the waterproof and dustproof performance of the SIM card holder, a sealing rib 4 is also provided on the SIM card holder, and a blocking rib 5 for blocking the sealing rib 4 is also provided between the sealing rib 4 and the elastic avoidance groove 3. As a result, the length of the SIM card holder is longer, so that a larger accommodation space needs to be provided in the terminal device, which increases the difficulty level of waterproof and dustproof of the terminal device.

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

[0064] In view of this, the embodiment of the present application provides a SIM card fixing mechanism, with a stopper on the seat body, and the abutting portion of the stopper extends into the card slot, which is used to abut the SIM card in the card slot, so that the SIM card is stably accommodated in the card slot. Compared with the traditional SIM card seat, the thickness corresponding to the elastic avoidance groove required by the elastic structure is reduced. In its own length direction, that is, the direction of insertion into the terminal device, the overall length of the SIM card fixing mechanism of the present application is shorter, which is more suitable for the situation where the space for accommodating the SIM card in the terminal device is limited, and can reduce the technical difficulty of waterproof sealing of the terminal device to a certain extent.

[0065] The terminal device provided in the embodiment of the present application belongs to a foldable electronic device, that is, a type of electronic device that can be folded and unfolded. For example, the terminal device can be a mobile phone, a tablet computer, a laptop computer (Laptop), a notebook computer (Notebook PC), a personal digital assistant (Personal Digital Assistant, PDA), a wearable device (such as a watch), a vehicle-mounted device, an augmented reality (Augmented Reality, AR) / virtual reality (Virtual Reality, VR) device, a sales terminal (POS, Point of sales terminal), a driving recorder, a walkie-talkie, a camera, a display, etc., but is not limited thereto.

[0066] See also Figure 2 , Figure 2 A schematic diagram of the three-dimensional structure of a terminal device in an unfolded state provided in some embodiments of the present application is shown, and the terminal device 1000 is taken as a mobile phone as an example for introduction and explanation.

[0067] The embodiment of the present application provides a terminal device 1000 , including a device body 1001 and a SIM card fixing mechanism 100 . A slot 1002 is provided on the device body 1001 , and the SIM card fixing mechanism 100 is inserted into the slot 1002 .

[0068] Among them, 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 arranged in the shell, a display screen electrically connected to the control panel, etc. The slot 1002 is used for the SIM card fixing mechanism 100 to be inserted. After the SIM card fixing mechanism 100 is inserted, the SIM card is electrically connected to the control panel in the device body 1001, thereby realizing the terminal device access to the corresponding communication network.

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

[0070] The overall length of the SIM card fixing mechanism 100 of the present application is shorter, so that the length of the slot 1002 adapted thereto can be designed to be shorter, saving a portion of the internal space of the device body 1001, thereby reducing the difficulty of designing waterproof and dustproof features of the terminal device at the slot 1002.

[0071] The above technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0072] The terminal device provided in the embodiment of the present application, on the basis of having the above-mentioned SIM card fixing mechanism 100, the depth of the slot 1002 on the device body 1001 can be set to be smaller, which is more conducive to the waterproof and dustproof design of the terminal device.

[0073] Please refer to Figure 3 and Figure 4 The present invention discloses a SIM card fixing mechanism 100, comprising a seat 10 and a stopper 20. The seat 10 is used to install and fix a SIM card 1003, and has a card slot 10a for accommodating the SIM card 1003; the slot profile of the card slot 10a is adapted to the outer profile of the SIM card 1003. Generally, the SIM card 1003 is a square structure, and the card slot 10a is also a square card slot 10a, which has four slot side walls adapted to the SIM card 1003.

[0074] The limit member 20 is flexible, for example, the limit member 20 can be made of silicone or rubber, and thus, the limit member 20 is arranged on the base body 10, for example, can be fixed on the base body 10 by injection molding; the limit member 20 includes an abutment portion 21 protruding toward the card slot 10a; the abutment portion 21 is used to provide a supporting 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 abutting portion 21, and then the other end thereof is pressed into the slot wall of the card slot 10a.

[0076] The above technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0077] The SIM card fixing mechanism 100 provided in the embodiment of the present application is provided with a limit member 20 on the seat body 10, and the abutment portion 21 of the limit member 20 extends into the card slot 10a to provide an abutment force for the SIM card 1003 accommodated in the card slot 10a. Compared with the traditional SIM card 1003 seat, the thickness corresponding to the elastic avoidance groove required by the elastic structure is reduced. In its own length direction, that is, the direction of insertion into the terminal device, the overall length of the SIM card fixing mechanism 100 of the present 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 Fig.10 In some embodiments, the seat body 10 includes a main body 11, a pushing top portion 12, and a middle portion 13 connected to the main body 11 and the pushing top portion 12. A card slot 10a is opened on the main body 11, and the side wall of the main body 11 is recessed toward the middle portion 13 to form an installation groove 10b connected to the card slot 10a, and the limit member 20 is arranged in the installation groove 10b.

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

[0080] An installation groove 10b is opened on the side wall of the main body 11. Specifically, the installation groove 10b is set on the side wall of the main body 11 close to the middle part 13. The limit member 20 is fixed in the installation groove 10b to improve the connection stability of the limit member 20 on the base body 10. Here, the limit member 20 can be set in the installation 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 installation slot 10b, the limiting body 22 has a first surface 22a facing the slot 10a, and the abutting portion 21 is disposed on the first surface 22a.

[0082] The limiting body 22 is the main part of the limiting member 20 accommodated in the installation groove 10b, and the first surface 22a of the limiting body 22 corresponds to the side wall of the main body 11 close to the middle part 13. It can be understood that the first surface 22a of the limiting body 22 is used to make up for the lack of the side wall caused by the installation groove 10b, that is, the first surface 22a of the limiting body 22 and the side wall of the main body 11 together enclose the slot 10a.

[0083] The abutting portion 21 is disposed on the first surface 22a, so that the abutting portion 21 faces the side wall of the SIM card 1003. Then, 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 abutting portion 21, and another part of the side wall abuts against the side wall of the main body 11.

[0084] Here, the first surface 22a and the side wall of the current main body 11 can have three positional relationships, namely, 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 in the side wall of the main body 11.

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

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

[0087] It can be understood that only the abutting portion 21 protrudes into the slot 10 a , and the first surface 22 a and the corresponding side wall of the main body 11 together form the side wall of the slot 10 a .

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

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

[0090] It can be understood that the thickness of the abutting portion 21 in the thickness direction of the seat body 10 is uneven. Here, the thickness of the abutting portion 21 refers to the distance from one end of the abutting portion 21 away from the first surface 22 a to the first surface 22 a.

[0091] That is, in the Z direction, the abutment portion 21 presents a structure in which one end is large and the other end is small. In this way, the force acting 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 also be understood that the side of the abutment portion 21 facing away from the first surface 22a has an inclined surface, and when abutting against the SIM card 1003, the inclined surface of the abutment portion 21 abuts against the side wall of the SIM card 1003, and the plane where the inclined surface is located forms an acute angle with the plane where the first surface 22a is located.

[0093] Here, the thickness variation trend of the contact portion 21 to the first surface 22a can be adjusted according to the actual contact requirement of the SIM card 1003. For example, the thickness of the contact portion 21 changes linearly or the thickness of the contact portion 21 changes slowly at first and then changes linearly. That is, the slope of the inclined surface of the contact portion 21 remains unchanged, or the slope of the inclined surface of the contact portion 21 changes first and then remains unchanged.

[0094] In this way, the abutting force of the abutting portion 21 with different thicknesses on the side wall of the SIM card 1003 is proportional to its thickness, that is, the abutting force of the abutting portion 21 with a greater thickness on the side wall of the SIM card 1003 is greater. Therefore, the entire abutting portion 21 applies a force at an angle to the horizontal direction to the side wall of the SIM card 1003, and when the abutting force is directed toward the inner wall of the bottom of the card slot 10a, the installation stability of the SIM card 1003 in the card slot 10a is higher.

[0095] Please refer to Figure 4 In some embodiments, the limiting body 22 has a second surface 22b set at an angle with 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 surface of the main body 11.

[0096] The second surface 22b is a surface facing the same direction as the slot opening of the card slot 10a, the top end 21a of the contact portion 21 is close to the second surface 22b, and the bottom end 21b of the contact portion 21 is far from the second surface 22b, so the top end 21a of the contact portion 21 is close to the slot opening of the card slot 10a, and the bottom end 21b of the contact portion 21 is close to the bottom of the slot. In this way, the entire contact portion 21 applies a horizontal downward force to the side wall of the SIM card 1003, that is, the abutting force is toward the inner wall of the bottom of the slot 10a, and at this time, the installation stability of the SIM card 1003 in the card slot 10a is higher.

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

[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. The first sub-card slot 10a1 and the second sub-card slot 10a2 are both 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] It can be understood that after adding the partition plate 30, the SIM card fixing mechanism 100 can accommodate two SIM cards 1003 at the same time, and the SIM cards 1003 are respectively arranged in the first sub-card slot 10a1 and the second sub-card slot 10a2, and corresponding limiting members 20 are arranged in the two sub-card slots 10a, and their abutting parts 21 extend into the corresponding sub-card slots 10a to meet the function of limiting the SIM card 1003.

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

[0101] In order to meet the installation requirements of the two limit members 20, the installation groove 10b is also divided by the partition plate 30 to form two sub-installation grooves 10b for accommodating the corresponding limit members 20. Since the first sub-installation groove 10b1 and the second sub-installation groove 10b2 are connected, the two limit members 20 can be formed in the corresponding sub-installation grooves 10b by a one-time in-mold injection molding. At the same time, the two sub-installation grooves 10b are connected, so that the two limit members 20 have a certain connection relationship. For example, the two limit members 20 can be formed in the corresponding sub-installation grooves 10b by a one-time in-mold injection molding. Since the two sub-installation grooves 10b are connected, the two limit members 20 are an integrally formed structure.

[0102] Furthermore, the two sub-mounting grooves 10b are staggered. It can be understood that in the thickness direction of the seat body 10, the inner walls of the two sub-mounting grooves 10b are not completely aligned, that is, the projections of the two partially overlap. In this way, the bottom wall of one sub-mounting groove 10b must extend into the groove space of the other sub-mounting groove 10b, so that a certain supporting force can be provided to the limiter 20 in the thickness direction of the seat body 10, further improving the installation stability of the limiter 20 in the installation groove 10b.

[0103] Please refer to Fig.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 side wall of the first sub-mounting groove 10b1 or the side wall of the second sub-mounting groove 10b2.

[0104] It can be understood that in the thickness direction of the seat body 10, the projection of the partition plate 30 partially overlaps with the projection of the sub-mounting groove 10b, and the partition plate 30 extending into the sub-mounting groove 10b also provides a certain supporting force to the limit member 20. At the same time, the partition plate 30 does not separate the two limit members 20, and the two limit members 20 still have a certain connection relationship. In this way, the structural strength of the two limit 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 abutting 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] It can be understood that the groove 20a can be formed on the second surface 22b of the limiting body 22, or the groove 20a can be formed on the surface of the top end portion 21a of the abutment portion 21; or the groove 20a can be formed on the second surface 22b of the limiting body 22 and the surface of the top end portion 21a of the abutment portion 21.

[0107] Here, the groove 20a is used to increase the deformation degree of the abutting portion 21 after being abutted, that is, after the groove 20a is added, the deformation amplitude of the abutting portion 21 is larger than when the groove 20a is not provided.

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

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

[0110] In some embodiments, the sealing portion 23 and the limiting body 22 are integrally formed.

[0111] It can be understood that the sealing portion 23 and the limiting body 22 are integrally formed on the seat body 10 by in-mold injection molding, so that the space thickness can be further saved.

[0112] Please refer to Fig.12 In some specific embodiments, the width g of the sealing portion 23 is greater than or equal to 0.55 mm, the width e of the abutting portion 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, when the SIM card size is the same, the SIM card fixing mechanism of the present application needs to increase by at least 1.3 mm. Compared with the traditional SIM card holder 1, the SIM card fixing mechanism provided by the present application can save 1.1 mm.

[0113] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
