Technical Field
[0001] The utility model relates to the technology in the field of memory cards, in particular to a combined structure of a CFe Type A memory card housing. Background Art
[0002] CFe is short for CFexpress, which is a memory card format, but this is not entirely accurate. CFexpress is a series of memory cards. With the continuous improvement of the performance of digital cameras / camcorders, the emergence of large-sized sensors and high-pixel photography / camera devices, and the popularization of 4K video and even higher-resolution recording, it can be foreseen that the current XQD cards and CFast cards will become increasingly strained, and there is an urgent need for a memory card with faster writing and reading speeds. Therefore, CFexpress cards have emerged. Currently, CFexpress has three different types: Type A, Type B, and Type C. There is no need to worry about inserting the wrong type of card into the device because they all have different shapes and are not interchangeable.
[0003] CFexpress Type A is the smallest among CFexpress cards and has a relatively slow reading and writing speed. Its size is 20mm×28mm×2.8mm, which is similar to the size of an SD card, but it is slightly smaller and thicker. Its maximum writing speed is 1GB / s. The main structure of the current CFe Type A memory card housing includes a base body and a cover plate. The base body is recessed with a receiving cavity for placing the CFe Type A memory card, and the cover plate is fixed on the base body to cover the opening of the receiving cavity. In the prior art, the cover plate is fixed by screwing, and a sealing ring needs to be placed between the cover plate and the base body. This structure has a complex assembly process, high cost, and insecure connection. Therefore, it is necessary to improve the current CFe Type A memory card housing. Summary of the Utility Model
[0004] In view of this, in view of the deficiencies of the prior art, the main purpose of the present utility model is to provide a combined structure of a CFe Type A memory card housing, which can effectively solve the problems of complex assembly process, high cost, and insecure connection of the existing CFe Type A memory card housing.

[0007] As a preferred solution, the lower cover is a metal cover plate structure, which is formed by stamping, with a simple structure and easy production.
[0008] As a preferred solution, a plurality of fixing parts are bent and extended from the periphery of the lower cover, and the plurality of fixing parts are embedded in the main body for fixation, with a simple structure and firm connection.
[0009] As a preferred solution, notches are formed on both side edges of the fixing part, and the notches are buried in the main body, so that the lower cover is more firmly combined with the main body and the lower cover is prevented from separating from the main body.
[0010] As a preferred solution, an embedding groove is recessed on the top surface of the main body, a glue dispensing groove is recessed on the bottom surface of the embedding groove, the embedding groove is located on the periphery of the opening of the receiving cavity, and the periphery of the upper cover is embedded in the embedding groove and fixedly bonded by the glue in the glue dispensing groove, with a simple structure, convenient assembly and firm connection.
[0011] As a preferred solution, both the embedding groove and the glue dispensing groove are annular to achieve a better sealing and fixing effect.
[0012] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:
[0013] By integrally forming and fixing the lower cover and the main body together to cover the notch, and cooperating with the upper cover fixedly bonded to the main body to cover the opening of the receiving cavity, there is no need to use screws for assembly, nor is it necessary to use a sealing ring. Its structure is simple, the assembly process is reduced, and the cost is greatly reduced. At the same time, the assembly connection is also more firm and reliable.

[0027] Please refer to Figures 1 to 5 as shown, which shows the specific structure of a preferred embodiment of the present utility model, including a main body 10, a lower cover 20 and an upper cover 30.
[0028] The main body 10 has an accommodating cavity 11 with an upward opening for accommodating the CFe Type A memory card 40. A notch 12 and a window 13 for the contact part 41 of the CFe Type A memory card 40 to be exposed are formed on the bottom surface of the main body 10. The window 13 is located in front of the notch 12, and both the window 13 and the notch 12 communicate with the accommodating cavity 11. In this embodiment, the main body 10 is made of plastic material. An embedded groove 14 is recessed on the top surface of the main body 10, and a glue dispensing groove 15 is recessed on the bottom surface of the embedded groove 14. The embedded groove 14 is located at the periphery of the opening of the accommodating cavity 11. Moreover, the embedded groove 14 and the glue dispensing groove 15 are annular to achieve a better sealing and fixing effect. The opening of the accommodating cavity 11 is larger than the outer contour of the CFe Type A memory card 40 so that the CFe Type A memory card 40 can be embedded into the accommodating cavity 11. Both the notch 12 and the window 13 are square.
[0029] The lower cover 20 is integrally formed and fixed to the main body 10 by inlaying and covers the notch 12. In this embodiment, the lower cover 20 is a metal cover plate structure and is formed by stamping. A plurality of fixing portions 21 are bent and extended from the periphery of the lower cover 20, and the plurality of fixing portions 21 are embedded in the main body 10 for fixing, with a simple structure and firm connection. Moreover, notches 201 are formed on both side edges of the fixing portion 21, and the notches 201 are buried in the main body 10, so that the lower cover 20 and the main body 10 are more firmly combined, preventing the lower cover 20 from separating from the main body 10.
[0030] The upper cover 30 is adhesively fixed to the main body 10 and covers the opening of the accommodating cavity 11. In this embodiment, the upper cover 30 is a metal cover plate and is formed by stamping. Of course, it can also be made of other materials, which is not limited. Moreover, the periphery of the upper cover 30 is embedded in the embedding groove 14 and is adhesively fixed by the glue (not shown in the figure) in the glue application groove 15, with a simple structure, convenient assembly and firm connection.
[0031] The assembly process of this embodiment is described in detail as follows:
[0032] First, the lower cover 20 and the upper cover 30 are formed by stamping. Then, the lower cover 20 is placed in an injection mold to form the main body 10 by injection molding. Then, the CFe Type A memory card 40 is embedded into the accommodating cavity 11 through the opening of the accommodating cavity 11. Then, glue is applied to the glue application groove 15. Finally, the periphery of the upper cover 30 is embedded in the embedding groove 14, and the upper cover 30 is adhesively fixed to the main body 10 by using the glue in the glue application groove 15.
[0033] The design focus of the present utility model is that: by integrally forming and fixing the lower cover to the main body to cover the notch, and cooperating with the upper cover adhesively fixed to the main body to cover the opening of the accommodating cavity, there is no need to use screws for assembly, nor to use a sealing ring. Its structure is simple, the assembly process is reduced, and the cost is greatly reduced. At the same time, the assembly connection is also more firm and reliable.
[0034] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
