Abstract
Description
Technical Field
[0001] This utility model relates to a memory card, specifically a novel memory card with a shielding structure. Background Technology
[0002] A memory card is a standalone storage medium used in digital products such as mobile phones, digital cameras, laptops, and MP3 players, and it is usually in the form of a card.
[0003] Existing memory cards have a complex and poorly designed structure, possessing only the single function of a memory card, resulting in poor functionality. Furthermore, they lack electromagnetic interference protection, making them prone to instability in complex electromagnetic environments. The inability to quickly dissipate heat also affects their stability over long-term use. In addition, existing memory cards lack physical protection, making them susceptible to wear and tear during use. Therefore, the inventors have improved the structure of the memory card. Utility Model Content
[0004] The purpose of this utility model is to provide a novel memory card with a shielding structure. It features a simple structure and reasonable design, functioning not only as a memory card but also as a SIM card, offering strong functionality. The shielding shell provides electromagnetic interference protection, ensuring stable operation of the SIM card and memory card body in complex electromagnetic environments. Simultaneously, the shielding shell, in contact with the SIM card and memory card body, also assists in heat dissipation, ensuring strong stability even after prolonged use. During use, neither the SIM card nor the memory card body comes into contact with external objects, providing physical protection and preventing wear and tear. This invention solves the problems mentioned in the aforementioned technical background.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel memory card with a shielding structure, comprising a memory card body fixed to a support body, an outer shell disposed on the outside of the support body, and the support body including a mounting part, on which a fixing part is fixed, and the mounting part being provided with a SIM card mounting chamber and a memory card mounting chamber located on one side of the SIM card mounting chamber; the outer shell including an upper shell and a lower shell disposed below the upper shell, a shielding shell disposed between the upper shell and the lower shell, and the upper shell including an upper positioning piece and a fixing part fixed to the upper positioning piece. The upper contact piece on the chip has a shielding shell fixed to the lower end face of the upper positioning piece, and the shielding shell is located between the upper positioning piece and the mounting part. In actual use, the lower end face of the shielding shell is in contact with the SIM card and memory card body. Therefore, the shielding shell can play a role in preventing electromagnetic interference to the SIM card and memory card body on the mounting part, ensuring that the SIM card and memory card body work stably in a complex electromagnetic environment. It also has physical protection and auxiliary heat dissipation functions. The lower housing includes a lower positioning piece and a lower contact piece fixed on the lower positioning piece. The lower positioning piece and the upper positioning piece are arranged facing each other and are used to wrap the support body.
[0006] Preferably, both the SIM card mounting chamber and the memory card mounting chamber extend through the mounting section. Limiting slots are formed on both sides of the memory card mounting chamber. When installing the memory card body, both ends of the memory card body are inserted from the side of the memory card mounting chamber away from the SIM card mounting chamber, and both ends are inserted into the two limiting slots. The two limiting slots limit the memory card body and ensure the stability of the memory card body. The SIM card mounting chamber is used to place the SIM card.
[0007] Preferably, the outer casing further includes an inner casing, wherein the inner casing is located between the mounting portion and the lower casing, and the inner casing includes an inner protective sheet and an inner contact sheet fixed on the inner protective sheet, the inner protective sheet being located below the mounting portion.
[0008] Preferably, the inner protective piece is fixed to the upper end face of the lower positioning piece, and the inner contact piece is fixed to the upper end face of the lower contact piece, thereby fixing the inner housing to the inside of the lower housing and making it an integral part of the lower housing. The inner housing can protect the SIM card and the memory card body.
[0009] Preferably, the length direction of the memory card body is the same as the length direction of the mounting part, and the memory card body is located between the upper contact piece and the inner contact piece.
[0010] Preferably, the upper end face of the memory card body is in contact with the shielding shell, and the lower end face of the memory card body is in contact with the inner contact piece. The shielding shell and the inner contact piece work together to limit the memory card body and prevent the memory card body from falling off the mounting part.
[0011] Preferably, the upper positioning plate and the inner protective plate are located at both ends of the fixing part, and both the upper positioning plate and the inner protective plate are fixed to the fixing part, so that the upper shell and the inner shell are integrated with the support body.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
