[0030] Please refer to Figures 1 to 6 This embodiment discloses a fixing structure for mounting a SIM card. The fixing structure includes a housing 1 and a card holder structure 4. The housing 1 has a mounting hole 101, and a SIM card 200 is fixed to one side of the card holder structure 4. When the card holder structure 4 is inserted into the mounting hole 101, the SIM card 200 is placed in the housing 1. With this configuration, by mounting the SIM card to one side of the card holder structure 4, the opening area of ​​the mounting hole 101 is smaller, thereby reducing the space occupied by the SIM card and the space required for removing and placing the SIM card.

[0031] This embodiment also discloses a communication terminal 100, which includes a fixing structure, a circuit board 2, and a spring clip 3. A card holder structure 4 is part of a housing 1. The housing 1 is part of the outer housing of the communication terminal 100. The circuit board 2 is disposed within the housing 1, and the spring clip 3 is disposed on the circuit board 2. When the card holder structure 4 is inserted into the mounting hole 101, the SIM card 200 within the card holder structure 4 extends into the housing 1 along with at least a portion of the card holder structure 4 through the mounting hole 101, thereby electrically connecting the SIM card 200 to the spring clip 3. This arrangement not only optimizes the opening area of ​​the mounting hole 101 in the housing 1 but also optimizes the mounting space of the spring clip 3 on the circuit board 2, making the overall structure of the communication terminal 100 more compact.

[0032] Please refer to Figures 1 to 6 The card holder structure 4 includes a base 41 and an elastic support 42 disposed on the base 41. The SIM card 200 is disposed within the elastic support 42. When the elastic support 42 is inserted into the mounting hole 101, the elastic support 42 elastically abuts against the wall of the mounting hole 101, and the SIM card 200 within the elastic support 42 is electrically connected to the spring contact 3. With this configuration, when the SIM card 200 is disposed within the elastic support 42, the inner wall of the elastic support 42 elastically abuts against the edge of the SIM card. At this time, the elastic support 42 provides an inward clamping force on the SIM card 200, making it difficult for the SIM card 200 to fall out of the elastic support 42. Simultaneously, the outer wall of the elastic support 42 elastically abuts against the mounting hole 101, and the elastic support 42 and the mounting hole 101 are interference-fitted. The elastic support 42 provides a certain degree of waterproofing to the housing 1, improving the service life of the communication terminal 100.

[0033] Currently, SIM cards 200 on the market are available in three types: standard SIM cards, Micro SIM cards, and Nano SIM cards. The dimensions of a standard SIM card are 25x15x0.76mm, a Micro SIM card is 15x12x0.76mm, and a Nano SIM card is 12.3x8.8x0.67mm. The size of the spring clip 3 is compatible with the type of SIM card 200. The SIM card 200 is inserted into the mounting hole 101 via the card slot structure 4 and electrically connected to the spring clip 3. The elastic support base 42 is compatible with the mounting hole 101. Thus, the size of the mounting hole 101 on the housing 1 is smaller than that required for a flip-type SIM card, optimizing the mounting space and improving the overall aesthetics of the housing 1.

[0034] Please refer to Figures 5 to 6 The base 41 includes a fixing plate 411 and a protrusion 412 disposed on the fixing plate 411. An elastic support 42 is sleeved around the protrusion 412, abutting against the fixing plate 411. At least a portion of the elastic support 42 protrudes from the protrusion 412, forming a groove 401. One side of the SIM card 200 is in contact with the top wall of the protrusion 412, and the elastic support 42 provides elastic clamping to the edge of the SIM card 200. In one embodiment, the shape and size of the protrusion 412 are the same as those of the SIM card 200, and the protrusion 412 provides a certain supporting force to the SIM card 200, making the SIM card 200 less prone to deformation. Simultaneously, when the SIM card 200 is placed in the groove 401, the elastic support 42 surrounding the protrusion 412 provides a certain elastic clamping force to the edge of the SIM card 200, making it less likely for the SIM card 200 to fall out of the groove 401.

[0035] Please refer to Figures 5 to 6 Specifically, a limiting groove 402 is provided on one side of the fixing plate 411, and a boss 412 is disposed within the limiting groove 402. The elastic support base 42 includes a U-shaped base 421 and a support portion 422 disposed on the base 421. The base 421 is disposed within the limiting groove 402, and the support portion 422 is sleeved around the boss 412. Preferably, the support portion 422 and the boss 412 are interference-fitted. When the SIM card 200 is placed in the groove 401, the boss 412 provides a certain supporting force to the SIM card 200 to prevent the SIM card 200 from deforming. At the same time, the support portion 422 of the elastic support base 42 can provide a certain elastic friction force to the edge of the SIM card 200 to prevent the SIM card 200 from falling out of the groove 401.

[0036] The elastic support 42 and the base 41 can be integrally formed or separately disposed. In one embodiment, the elastic support 42 is integrally formed with the base 41 by injection molding to improve the structural strength of the elastic support 42 and the base 41, making it less likely for the elastic support 42 and the base 41 to detach. In another embodiment, the elastic support 42 is assembled onto the boss 412 of the base 41 by means of manual operation or automated equipment, which can also achieve the connection between the base 41 and the elastic support 42, and there is no limitation here.

[0037] The elastic support base 42 is made of soft rubber, processed from natural or synthetic rubber. In one embodiment, the synthetic rubber is TPU (thermoplastic polyurethane rubber) or TPE (thermoplastic elastomer), which is not limited here. The base 41 is made of hard rubber, which is an engineering plastic. In one embodiment, the engineering plastic is PC (polycarbonate) or ABS (acrylonitrile-butadiene-styrene copolymer), which is not limited here. When the SIM card is placed in the groove 401, the hard rubber protrusion 412 can provide a certain degree of support for the SIM card 200 to prevent the SIM card 200 from deforming. The soft rubber support portion 422 can provide a certain degree of elastic friction for the SIM card 200 to prevent the SIM card 200 from falling out of the groove 401.

[0038] Please refer to Figures 5 to 6 The outer wall of the elastic support base 42 is provided with a protrusion 423, which elastically abuts against the wall of the mounting hole 101. Specifically, the annular protrusion 423 is provided on the outer wall of the support portion 422, and the annular protrusion 423 is located close to the base portion 421. When the elastic support base 42 is inserted into the mounting hole 101, the protrusion 423 is squeezed by the wall of the mounting hole 101, so that the protrusion 423 and the wall of the mounting hole 101 achieve an interference fit, thereby sealing the mounting hole 101 and providing a certain degree of waterproof performance, preventing external moisture or liquid from entering the mounting hole 101 and damaging the circuit board 2.

[0039] Please refer to Figures 2 to 6 The elastic support base 42 has a notch 403 on one side, which communicates with the groove 401. The notch 403 is located at the top of the support portion 422, and is provided to facilitate the insertion and removal of the SIM card 200. In this embodiment, the notch 403 and the protrusion 423 are arranged opposite to each other on the outer wall of the support portion 422 relative to the groove 401, which can improve the overall structural strength of the elastic support base 42.

[0040] Please refer to Figures 2 to 6The outer wall of the elastic support base 42 is also provided with a snap-fit ​​part 424, and the wall of the mounting hole 101 has a groove 102. When the elastic support base 42 is inserted into the mounting hole 101, the snap-fit ​​part 424 and the groove 102 snap together. Specifically, the snap-fit ​​part 424 and the groove 102 are arranged opposite to each other along the docking direction between the mounting base structure 4 and the mounting hole 101. When the elastic support base 42 is inserted into the mounting hole 101, the snap-fit ​​part 424 and the groove 102 engage to improve the stability of the connection between the elastic support base 42 and the mounting hole 101.

[0041] Please refer to Figure 1 Specifically, the housing 1 has a recess 11, and an assembly hole 101 is provided in the recess 11. When the elastic support 42 and the boss 412 are inserted into the assembly hole 101 together, the fixing plate 411 cooperates with the recess 11. In this embodiment, the shape of the recess 11 matches the shape of the fixing plate 411. Specifically, the recess 11 is rectangular, and the fixing plate 411 is rectangular. It can also be any other shape to achieve the purpose of the fixing plate 411 being embedded in the recess 11, and there is no limitation here. By embedding the fixing plate 411 in the recess 11, on the one hand, the stability of the connection between the card holder structure 4 and the housing 1 can be improved, and separation between the card holder structure 4 and the housing 1 can be avoided. On the other hand, the surface of the fixing plate 411 and the surface of the housing 1 remain on the same plane, which improves the overall aesthetics of the communication terminal 100.

[0042] Please refer to Figure 1 as well as Figures 5 to 6 The fixing plate 411 has a first connecting hole 404 and the recess 11 has a second connecting hole 103. The first connecting hole 404 and the second connecting hole 103 are arranged opposite to each other. The card holder structure 4 also includes a fastener 300, which passes through the first connecting hole 404 and connects to the second connecting hole 103 to ensure a firm connection between the card holder structure 4 and the housing 1.

[0043] In summary, this embodiment discloses a fixing structure, which includes a housing 1 and a card holder structure 4. The housing 1 has an assembly hole 101, and a SIM card is fixed on one side of the card holder structure 4. When the card holder structure 4 is inserted into the assembly hole 101, the SIM card 200 is disposed in the housing 1. This reduces the space occupied by the SIM card 200 and the space required for removing and placing the SIM card 200.
