[0037] like Figures 1 to 3 As shown, some embodiments of the utility model provide a U disk, which is mainly used for transferring files, backing up data, installing systems, etc., to prevent dust, liquid or other impurities from entering the data connector of the U disk, thereby increasing the service life of the U disk, ensuring the sensitivity of the data connector, and improving the convenience of carrying the U disk.

[0038] The USB flash drive includes a body 100 , a flexible connector 200 and an elastic cap 300 .

[0039] A data connector 110 is disposed on one side of the body 100 .

[0040] It is understandable that the data connector 110 can be disposed on any side of the body 100 and can be specifically set according to actual conditions.

[0041] Specifically, in this embodiment, the data connector 110 is disposed on one side of the body 100 in the thickness direction, and the opening direction of the data connector 110 is the same as the thickness direction of the body 100 .

[0042] In addition, one end of the flexible connector 200 is connected to the body 100 .

[0043] It should be noted that the connection method between the flexible connector 200 and the main body 100 includes any one of threaded connection, bonding, magnetic connection, one-piece molding and clamping, which can be specifically set according to actual conditions.

[0044] In this embodiment, the elastic cap 300 is disposed at an end of the flexible connector 200 away from the body 100 , and the elastic cap 300 defines a receiving groove 310 .

[0045] It should be noted that the flexible connector 200 can be bent so that the data connector 110 can be accommodated in the receiving groove 310 , so that the elastic cover cap 300 can be covered on the data connector 110 .

[0046] Furthermore, the inner wall of the receiving groove 310 abuts against the outer wall of the data connector 110 to improve the stability of the connection between the elastic cap 300 and the data connector 110 .

[0047] It should be noted that the elastic cap 300 has elastic force, so that when the elastic cap 300 is connected to the data connector 110, the data connector 110 can slightly open the elastic cap 300. At the same time, the elastic cap 300 stores elastic potential energy and tends to return to its original state.

[0048] That is to say, at this time, the elastic cover cap 300 has elastic force on the data connector 110 to further improve the stability of the connection between the elastic cover cap 300 and the data connector 110, thereby effectively preventing external dust, liquid or other impurities from entering the data connector 110, thereby improving the service life of the USB flash drive.

[0049] In this embodiment, the data connector 110 is arranged on one side in the thickness direction of the main body 100 to avoid the situation where the opening of the data connector 110 is vertically facing upward when the USB flash drive is placed on a horizontal surface, thereby increasing the height of the data connector 110 in the vertical direction. This can effectively prevent liquid from entering the data connector 110.

[0050] Exemplarily, if the opening direction of the data connector 110 is vertically downward, since the elastic cover cap 300 is covered on the data connector 110 to increase the height of the opening of the elastic cover cap 300 in the vertical direction, it is equivalent to increasing the height of the opening of the data connector 110 in the vertical direction, that is, increasing the height of the external liquid entering the data connector 110, so as to improve the protection quality of the data connector 110.

[0051] like Figure 3As shown, in some embodiments of the utility model, along the depth direction of the accommodating groove 310, the inner diameter of the accommodating groove 310 gradually decreases from the notch of the accommodating groove 310 to the bottom of the accommodating groove 310, so that when the elastic cover cap 300 is connected to the data connector 110, the convenience of the connection between the elastic cover cap 300 and the data connector 110 can be ensured while ensuring the stability of the connection between the elastic cover cap 300 and the data connector 110.

[0052] The notch of the accommodating groove 310 is larger than the outer diameter of the data connector 110 , so as to improve the convenience of connecting the elastic cap 300 with the data connector 110 .

[0053] In addition, the inner diameter of the bottom of the accommodating groove 310 is smaller than the outer diameter of the data connector 110, so that when the elastic cover cap 300 is covered on the data connector 110, the data connector 110 can open the inner wall of the bottom of the accommodating groove 310, so that the inner wall of the elastic cover cap 300 and the inner wall of the data connector 110 form a mutually abutting structure, which can not only improve the stability of the connection between the elastic cover cap 300 and the data connector 110, but also protect the data connector 110, prevent external dust, liquid or other impurities from entering the data connector 110, and improve the service life of the USB flash drive.

[0054] In some embodiments of the present invention, the length of the flexible connector 200 is L, wherein the value range of L is 2 cm ≤ L ≤ 10 cm.

[0055] It can be understood that the value range of L includes any range of 2cm≤L≤10cm, 3cm≤L≤10cm, 4cm≤L≤10cm, 5cm≤L≤10cm, 6cm≤L≤10cm, 7cm≤L≤10cm, 8cm≤L≤10cm, and 9cm≤L≤10cm, and can be set according to actual conditions.

[0056] It should be noted that by adjusting the length of the flexible connector 200 , not only can the production cost be reduced, but also the compactness of the USB flash drive can be improved for easier portability.

[0057] Specifically, when the elastic cap 300 covers the data connector 110 , the flexible connector 200 bends and forms a closed ring structure with the elastic cap 300 and the body 100 to form a hanging structure.

[0058] It can be understood that the USB flash drive provided by the present invention can be hung by the flexible connector 200, which further improves the convenience of the USB flash drive during use or placement and enhances the user experience.

[0059] like Figure 1 and Figure 5 As shown, in some embodiments of the present invention, the flexible connector 200 is any one of a rubber strip, a PET strip, a silicone strip or a nylon strip.

[0060] It should be noted that rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce a large deformation under a very small external force, and can return to its original shape after the external force is removed.

[0061] Among them, silicone has a long service life and is not easily affected by ultraviolet rays, oxidation, acid, alkali, water, oil and other substances. Therefore, it will not age, yellow, crack or harden. Silicone can maintain stability under extreme temperature conditions and will not expand due to high temperature or harden due to low temperature. Silicone can maintain its softness in various environments and is not easy to deform or crack.

[0062] In addition, nylon has outstanding wear resistance. When stretched to 3-6%, its elastic recovery rate can reach 100%, and it can withstand tens of thousands of flexures without breaking.

[0063] It should be noted that PET (polyethylene glycol terephthalate) has good mechanical properties, its impact strength is 3 to 5 times that of other films, it has good folding resistance, and it is resistant to oil, fat, dilute acid, dilute alkali, and most solvents.

[0064] In this embodiment, the rubber strip can be a TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer rubber) strip. TPU has excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, low temperature resistance, and good oil resistance, chemical resistance and environmental resistance.

[0065] like Figure 4 As shown, in some embodiments of the present invention, a first connection portion 600 is provided at one end of the flexible connector 200 close to the body 100 , and a second connection portion 700 is provided at one side of the body 100 .

[0066] The first connection portion 600 is connected to the second connection portion 700 to connect the flexible connector 200 to the body 100 .

[0067] It can be understood that by detachably connecting the flexible connector 200 to the body 100, installation or removal of the flexible connector 200 and the body 100 is facilitated, and replacement of the flexible connector 200 is facilitated, thereby improving user experience.

[0068] In some embodiments of the present invention, the first connection portion 600 is a snap-fit ​​groove, and the second connection portion 700 is a protrusion.

[0069] Among them, the protrusion is clamped in the clamping groove to connect the elastic cover cap 300 with the data connector 110, which can not only improve the stability of the connection between the flexible connector 200 and the main body 100, but also improve the installation or disassembly efficiency between the flexible connector 200 and the main body 100.

[0070] In some other embodiments of the present invention, the first connection portion 600 is a bolt, the second connection portion 700 is a screw hole, and the first connection portion 600 is threadedly connected to the second connection portion 700.

[0071] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the depth of the receiving groove 310 is greater than or equal to the length of the data connector 110 to ensure that the elastic cap 300 can completely cover the data connector 110 .

[0072] Preferably, in this embodiment, the depth of the receiving groove 310 is equal to the length of the data connector 110 to improve the space utilization of the USB flash drive.

[0073] like Figure 4 As shown, in some embodiments of the present invention, at least one first magnet 400 is disposed on a side of the body 100 facing the data connector 110 , and the first magnet 400 is adjacent to the data connector 110 .

[0074] It can be understood that the number of the first magnets 400 can be one, two, or any number greater than two.

[0075] Wherein, at least one second magnet 500 is disposed on the edge of the elastic cap 300 , and the first magnet 400 is magnetically connected to the second magnet 500 .

[0076] In this embodiment, the first magnet 400 and the second magnet 500 attract each other with opposite poles, so as to further enhance the stability of the connection between the elastic cap 300 and the data connector 110 .

[0077] It can be understood that the number of the second magnets 500 can be one, two, or any number greater than two.

[0078] It should be noted that the first magnet 400 is embedded on one side of the body 100 in the thickness direction, and the second magnet 500 is embedded on the edge of the notch of the elastic cap 300 .

[0079] like Figure 4As shown, in some embodiments of the present invention, there are plural first magnets 400 and plural second magnets 500 .

[0080] The number of the first magnet 400 and the second magnet 500 can be two or more than two, and can be set according to actual conditions.

[0081] Furthermore, a plurality of the first magnets 400 surround the data connector 110 , and the plurality of the first magnets 400 are disposed at intervals, and a plurality of the second magnets 500 are disposed at intervals along the edge of the elastic cap 300 .

[0082] In addition, the distance between two adjacent first magnets 400 and the distance between two adjacent second magnets 500 can be specifically set according to actual conditions.

[0083] In this embodiment, a plurality of the first magnets 400 are arranged at equal intervals around the circumference of the data connector 110 .

[0084] It should be noted that the number of the first magnets 400 is equal to the number of the second magnets 500 , and each of the first magnets 400 is connected to a corresponding second magnet 500 .

[0085] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0086] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0087] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
