[0002] Conventional SIM card holders and SD card holders are placed in parallel on the circuit board, occupying a large space and restricting the layout of other circuits. In addition, conventional SIM card holders and SD cards are also limited by the size of the product casing. Utility Model Content

[0003] In order to solve the technical problems that the conventional SIM card holder and SD card holder are placed in parallel on the circuit board, occupying a large space and restricting the layout of other circuits, and in addition, the conventional SIM card holder and SD card are also limited by the size of the product shell, one purpose of the utility model is to provide a universal SD and SIM card tooling.

[0004] To achieve the above-mentioned purpose, an embodiment of the present invention provides a universal SD and SIM card tooling, including a circuit board with a card slot on its surface; a board with a metal contact piece at one end, the metal contact piece being inserted into the card slot; an SD card holder installed on one side of the board; and a SIM card holder installed on the other side of the board.

[0005] By inserting the metal contact piece on the board into the card slot and installing the SD card holder and SIM card holder on both sides of the board, the space required for installing the SD card holder and SIM card holder on the circuit board can be reduced, thereby improving the space utilization of the circuit board.

[0023] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0025] Refer to the following Figures 1 to 6 A universal SD and SIM card tooling is described according to some embodiments of the present invention.

[0026] like Figures 1 to 6 As shown, an embodiment of the present invention provides a universal SD and SIM card tooling, including a circuit board 1, a board card 3, an SD card holder 5 and a SIM card holder 6.

[0027] Specifically, a card slot 2 is provided on the surface of the circuit board 1; a board 3 is provided with a metal contact piece 4 at one end, and the metal contact piece 4 is inserted into the card slot 2; an SD card holder 5 is installed on one side of the board 3; and a SIM card holder 6 is installed on the other side of the board 3.

[0028] During the process of installing the SD card holder 5 and the SIM card holder 6 on the circuit board 1, since pins are provided on the SD card holder 5 and the SIM card holder 6, and solder pads corresponding to the pins of the SD card holder 5 and the pins of the SIM card holder 6 are provided on both sides of the board 3, the SD card holder 5 and the SIM card holder 6 can be respectively mounted on the solder pads on both sides of the board 3, thereby completing the installation of the SD card holder 5 and the SIM card holder 6.

[0029] After the SD card holder 5 and the SIM card holder 6 are installed, the metal contact piece 4 is inserted into the card slot 2 of a fixed package size opened on the circuit board 1. The size of the card slot 2 is adapted to the metal contact piece 4, and when the board card 3 needs to be replaced on another circuit board, the board card 3 can be directly pulled out from the card slot 2, which facilitates the transplantation of the board card 3. Since the board card 3 is perpendicular to the circuit board 1, compared with the prior art in which the SD card holder 5 and the SIM card holder 6 are installed parallel to the circuit board 1, this application reduces the installation area of ​​the SD card holder 5 and the SIM card holder 6, and improves the space utilization rate of the circuit board 1.

[0030] Furthermore, circuit board 1 features multiple circuits, and all circuit traces are impedance-matched to reduce energy loss and signal reflections, thereby improving circuit performance and stability. Equalizing the length of the circuit traces ensures signal synchronization and timing requirements, reducing variations in signal transmission delays and improving system stability and reliability.

[0031] like Figures 2 to 6 As shown, in one embodiment of the present invention, a positioning hole 7 is opened on the circuit board 1 , and a limiting member 8 is fixedly connected to the board 3 , and the limiting member 8 is inserted into the positioning hole 7 .

[0032] By providing a positioning hole 7 on the circuit board 1, the positioning hole 7 is close to the card slot 2, and a limiting member 8 is fixedly connected to the card 3. The limiting member 8 is inserted into the positioning hole 7. Then, through the cooperation between the limiting member 8 and the positioning hole 7, the card 3 can be initially fixed, thereby preventing the card 3 from shaking during the soldering process on the circuit board 1. In addition, the limiting member 8 can also make the operator clear about the insertion position of the card 3, preventing the card 3 from being inserted backwards during soldering.

[0033] like Figures 2 to 6 As shown, in one embodiment of the present invention, the length of the circuit board 1 close to the metal contact piece 4 is greater than the length of the positioning hole 7, and the length of the metal contact piece 4 is less than or equal to the length of the positioning hole 7.

[0034] By making the length of the side of the circuit board 1 close to the metal contact piece 4 greater than the length of the positioning hole 7, and the length of the metal contact piece 4 less than or equal to the length of the positioning hole 7, the metal contact piece 4 can be inserted into the positioning hole 7, while preventing the board 3 from entering the positioning hole 7. When the metal contact piece 4 is just inserted into the card slot 2, the board 3 just contacts the circuit board 1, which serves as a warning, making it easy for the operator to know that the board 3 has been installed.

[0035] The utility model has the following advantages:

[0036] The metal contact piece 4 is inserted into the card slot 2 opened on the circuit board 1. Since the board 3 is perpendicular to the circuit board 1, compared with the prior art in which the SD card holder 5 and the SIM card holder 6 are installed parallel to the circuit board 1, this application reduces the installation area of ​​the SD card holder 5 and the SIM card holder 6, and improves the space utilization of the circuit board 1.

[0037] In this utility model, the terms "install," "connect," "connect," and "fix" should be understood in a broad sense. For example, "connect" can refer to a fixed connection, a detachable connection, or an integral connection; "connected" can refer to a direct connection or an indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0038] In the description of the present invention, it should be understood that the terms "inside" and "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0039] Throughout this specification, terms such as "one embodiment," "some embodiments," and "specific embodiments" mean that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
