The elastic clamping structure is arranged on two opposite sides of the base and is approximately symmetrical to a central axis of the base. Wherein, each clamping structure has a guiding part, a bending part and a receiving part, and the receiving part forms a groove, and the memory card slides into the groove along the guiding part, and with the help of the clamping structure, The restoring elastic force fixes the memory card in the groove, wherein the bending part connects the guiding part and the receiving part, a first opening is formed between the bending parts of the clamping structure, and the The width of the first opening is smaller than the width of the memory card.

In a preferred embodiment, the memory card fixing device is substantially in the shape of a ㄇ.

In a preferred embodiment, the clamping structure is made of metal.

In a preferred embodiment, the base is made of metal.

In a preferred embodiment, the clamping structure is integrally formed with the base.

In a preferred embodiment, the memory card fixing device is a stainless steel shrapnel.

In a preferred embodiment, each of the clamping structures further includes a carrying portion connecting the base and the receiving portion, wherein the carrying portion extends from the outside of the base toward the central axis for carrying the memory card.

In a preferred embodiment, a second opening is formed between the carrying parts of the two clamping structures, and the width of the second opening is smaller than the width of the first opening. The memory card fixing device of the present invention not only has the advantages of low cost and convenient use, but also can be widely used in mobile phones or other electronic products equipped with memory cards.

Detailed ways

Please refer to Fig. 2 and 3 together, the memory card fixing device 40 of the present embodiment can be arranged in a mobile phone, in order to fix a memory card S inside the mobile phone, and make it connect with a connector 30 inside the mobile phone Keep the electrical connection (as shown in Figure 3). The memory card S in this embodiment can be, for example, a Subscriber Identity Module (SIM card).

As shown in FIG. 2 , the aforementioned memory card fixing device 40 is, for example, an integrally formed stainless steel sheet, which mainly includes a base 41 and two elastic clamping structures 42 . Wherein, the aforementioned two clamping structures 42 are approximately symmetrical to a central axis C of the base 41 , and respectively extend upwards from both sides of the base 41 , so that the memory card fixing device 40 is approximately in the shape of a ㄇ. However, the aforementioned base 41 and clamping structure 42 can be made of other metal materials or flexible materials in addition to stainless steel. In addition, the base 41 and the clamping structure 42 can also be combined with each other by bonding or assembling. To form the aforementioned memory card fixing device 40 .

In FIG. 2 , each clamping structure 42 has a guiding portion 43 , a bending portion 44 , a receiving portion 45 and a bearing portion 46 respectively. The bending portion 44 connects the guiding portion 43 and the receiving portion 45 , The carrying portion 46 is connected to the base 41 and the accommodating portion 45 , wherein the carrying portion 46 extends from the outside of the base 41 toward the central axis C for supporting the memory card S. As shown in FIG. In particular, a first opening 44' is formed between the bending parts 44 of the two clamping structures 42, and a second opening 46' is formed between the bearing parts 46 of the two clamping structures 42, wherein The width W2 of the second opening 46' is smaller than the width W1 of the first opening 44'.

Then please refer to FIG. 3 , the memory card fixing device 40 in this embodiment is fixedly connected to the connector 30 inside a mobile phone. Since the width of the first opening 44' is slightly smaller than the width of the memory card S, it will contact the guide part 43 and prop the two clamping structures 42 outward during the process of pressing the memory card S. Open (shown in the direction of the arrow in FIG. 3 ), at this time, the memory card S can slide into the groove 45 ′ formed by the accommodating portion 45 along the slope of the guiding portion 43 . Then, the memory card S can be fixed in the groove 45' formed by the accommodating part 45 (as shown in FIG. 4 ) through the restoring elastic force of the left and right clamping structures 42, so that the memory card S can be firmly connected with the device 30 is electrically connected. Conversely, when the memory card S is to be taken out, the left and right clamping structures 42 can be opened outward with bare hands, so that the width W1 of the first opening 44' is slightly larger than the width of the memory card S. The bearing part 46 on the bottom side of 45 ′ can push the memory card S upwards out of the first opening 44 ′ and out of the memory card fixing device 40 .

To sum up, the present invention provides a memory card fixing device, which not only has the advantages of low cost and convenient use, but also can be widely used in mobile phones or other electronic products equipped with memory cards.

Although the present invention is disclosed above with the foregoing preferred embodiments, it is not intended to limit the present invention. Any person familiar with the art may make various equivalent changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the claims.
