Technical Field

[0001] This utility model relates to the technical field of SIM card holders, and more specifically, to a SIM card holder with a spring-loaded self-fixing arm. Background Technology

[0002] As electronic products rapidly evolve towards miniaturization, thinness, and integration, the demand for simplified SIM card slot structures, improved assembly efficiency, and optimized user experience is becoming increasingly urgent.

[0003] In existing technologies, SIM card holders generally adopt a structure of "card tray + card holder" or "card holder + top cover + latch". The SIM card needs to be inserted into the card tray first and then inserted into the card holder, or the SIM card needs to be locked by the top cover and latch after it is inserted into the card holder. This type of structure has the problems of a large number of parts and complicated assembly process. The card tray is easy to lose, the latch operation is cumbersome, and there are also problems such as poor contact between the SIM card and the card holder and inconvenience in removing the card during the insertion and removal process.

[0020] Reference Figures 1-5 The image shown is a preferred embodiment of the present invention.

[0021] The self-fixing SIM card holder with spring arm 210 provided by this utility model includes a plastic body, which includes a base 100 and two side plates 200 arranged opposite to each other. The two side plates 200 and the base 100 enclose a cavity for accommodating the SIM card. A first slot 201 with a hollow shape is provided on a side plate 200. The first slot 201 extends laterally, and the side plate 200 forms a spring arm 210 with both ends integrally connected to the side plate 200 under the action of the first slot 201. The spring arm 210 and the base 100 are arranged vertically and vertically. The spring arm 210 has an abutment part 211 protruding towards the receiving cavity. A terminal assembly 500 for electrical connection with a SIM card is connected to the base 100. When the SIM card is inserted into the receiving cavity, it is elastically abutted against the outer peripheral wall of the SIM card by the abutment part 211, thereby achieving self-fixation of the SIM card.

[0022] The self-locking SIM card holder with spring arm 210 described above has a spring arm 210 that has elastic deformation capability along the radial direction of the receiving cavity. When the SIM card is inserted into the receiving cavity, the spring arm 210 drives the abutment part 211 to elastically abut against the outer peripheral wall of the SIM card through elastic deformation, thereby achieving self-locking of the SIM card. In this way, there is no need for additional components such as card trays and latches. The elastic clamping structure of the spring arm 210 simplifies the card holder and assembly process, reduces manufacturing costs, and ensures stable SIM card fixation and convenient insertion and removal through the elastic abutment method. This effectively solves the problems of existing SIM card holders having many parts and cumbersome operation, improving product practicality and user experience.

[0023] The contact portion 211 is a bent, arc-shaped protrusion.

[0024] Specifically, the two side plates 200 extend upward along the two sides of the base 100. In this way, the two side plates 200 extend upward along the two sides of the base 100, making the side wall structure of the accommodating cavity more tightly connected with the base 100, thus enhancing the overall structural strength of the plastic body; at the same time, this layout can accurately enclose an accommodating cavity that fits the size of the SIM card, improving the regularity of SIM card placement.

[0025] In a preferred embodiment, one side plate 200 is provided with a spring arm 210, and the other side plate 200 is provided with a plurality of first limiting protrusions 220 protruding toward the receiving cavity. The plurality of first limiting protrusions 220 are arranged at intervals along the length direction of the side plate 200. In this way, the plurality of first limiting protrusions 220 on the two side plates 200 can limit the SIM card from both sides, preventing the SIM card from wobbling left and right in the receiving cavity, thus improving the positional accuracy of the SIM card after installation. Moreover, the interval arrangement not only ensures the limiting effect but also reduces the contact area with the SIM card, thereby reducing the frictional resistance during insertion and removal.

[0026] Specifically, the abutment portion 211 on one side plate 200 is arranged opposite to the first limiting protrusion 220 on the other side plate 200 to clamp and limit the two sides of the SIM card. In this way, the abutment portion 211 and the first limiting protrusion 220 on the other side plate 200 are arranged opposite to each other to form a clamping structure for the two sides of the SIM card. Combined with the elastic abutment of the spring arm 210, the SIM card fixing effect is further improved, preventing the SIM card from detaching from the electrical connection with the terminal assembly 500 due to vibration, shaking, etc., and ensuring communication stability.

[0027] In a preferred embodiment, the base 100 has a second strip groove 101 that is vertically aligned with and communicates with the first strip groove 201, and the second strip groove 101 is hollow. In this way, the second strip groove 101 on the base 100 is vertically aligned with and communicates with the first strip groove 201, which further increases the deformation space of the elastic arm 210 and makes the elastic recovery performance of the elastic arm 210 better; at the same time, the hollow second strip groove 101 also reduces the overall weight of the plastic body, which is in line with the design trend of lightweight electronic components.

[0028] The plastic body also includes a rear end plate 300 extending upward along the rear edge of the base 100. The rear end plate 300 is arranged between the two side plates 200. The rear end plate 300 is provided with a plurality of second limiting protrusions 310 protruding towards the receiving cavity. The plurality of second limiting protrusions 310 are spaced apart along the length direction of the rear end plate 300 to limit the rear end of the SIM card. In this way, the rear end plate 300 and the second limiting protrusions 310 can limit the rear end of the SIM card. Together with the first limiting protrusions 220 of the side plates 200, multi-directional positioning of the SIM card is achieved, preventing the SIM card from being inserted too deeply when inserted into the receiving cavity. At the same time, the rear end plate 300 connects the two side plates 200, which also enhances the structural stability of the plastic body.

[0029] Specifically, the base 100, the two side plates 200, and the rear plate 300 are integrally injection molded. This integral injection molding reduces assembly steps between components and improves production efficiency. Simultaneously, the integrally molded structure avoids assembly gaps, enhances the sealing performance and structural strength of the plastic body, and reduces the risk of SIM card positioning failure due to component loosening.

[0030] In this embodiment, a front opening 401 is formed between the two side plates 200 at the front end of the base 100, and the front opening 401 communicates with the receiving cavity. The base 100 has a hollowed-out notch 102, which is aligned with and communicates with the front opening 401, together forming a card removal opening 400 for SIM card insertion and removal. This provides ample operating space for SIM card insertion and removal, improving the convenience for users; at the same time, the opening structure also facilitates cleaning and maintenance of the inside of the receiving cavity.

[0031] In this embodiment, the side plate 200 has a front end portion 230 extending to the front end of the base 100. The front end portion 230 is provided with at least one third limiting protrusion 231 protruding towards the receiving cavity. The third limiting protrusion is arranged opposite to the second limiting protrusion 310 to clamp and limit the front and rear ends of the SIM card. This clamping and limiting of the front and rear ends of the SIM card, combined with the limiting structures on both sides, forms a full circumferential positioning of the SIM card, further improving the stability of the SIM card after installation and preventing it from shifting back and forth during use.

[0032] The first limiting protrusion 220, the second limiting protrusion 310, and the third limiting protrusion 231 are hemispherical, rectangular, or the like.

[0033] Specifically, the base 100 has multiple terminal through holes 103, the terminal assembly 500 is installed in the base 100, and the terminal assembly 500 is integrally formed with plastic. The upper part of the terminal assembly 500 protrudes through the terminal through holes 103 and is exposed in the receiving cavity, and the outer periphery of the terminal assembly 500 is embedded in the side plate 200.

[0034] The outer periphery of the terminal assembly 500 has an upwardly bent and extended insert section 510 that is embedded in the side plate 200.

[0035] The terminal assembly 500 is integrally molded with the plastic body, with the side plate 200 embedded in the side and the terminal through hole 103 protruding from the top. This not only improves the connection strength between the terminal assembly 500 and the plastic body, preventing the terminal assembly 500 from loosening, but also improves the overall strength of the side plate 200. At the same time, it ensures stable contact between the top of the terminal assembly 500 and the SIM card, improving the reliability of the electrical connection. In addition, the integrally molded structure simplifies the manufacturing process and reduces assembly errors.

[0036] Use case: Refer to Figure 5 As shown, the SIM card is placed in the receiving cavity and locked by the spring arm 210, the first limiting protrusion 220, the second limiting protrusion 310 and the third limiting protrusion 231. Then, the initially fixed SIM card can be further locked by the two pressure strips 610 inside the housing 600, which increases the reliability of the product.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
