Description

Technical Field

[0001] This utility model relates to the field of memory card technology, specifically to an adapter board and a disk reader equipped with the adapter board. Background Technology

[0002] CFexpress cards represent a new storage standard that prioritizes ultimate speed and performance. With the continuous improvement of digital camera performance, larger sensor sizes, the emergence of high-resolution models, and the widespread adoption of 4K video recording, existing XQD and CFast cards are increasingly unable to meet the demands of high-bitrate read and write operations, creating a pressing market need for faster storage solutions. To address this, the CompactFlash Association (CFA) has launched a new generation of high-speed storage card specifications—CFexpress 2.0.

[0003] However, the read and write speeds of CFexpress high-speed card readers currently on the market are generally only 10G / s, which greatly limits the read and write speeds of CFexpress cards. Utility Model Content

[0004] To address at least one of the aforementioned problems, according to one aspect of the present invention, an adapter plate is provided.

[0005] The adapter board includes an M.2 connector and a CFexpress interface that are electrically connected. Therefore, when a CFexpress card needs to be read, the CFexpress card can be inserted into the CFexpress interface of the adapter board first, and then the M.2 connector of the adapter board can be inserted into a disk reader with an M.2 interface, enabling the CFexpress card to be read at a speed of up to 32 GB / s.

[0006] In some embodiments, the adapter board further includes a first circuit board on which the M.2 plug and the CFexpress interface are electrically connected to achieve electrical connection between them. Thus, the M.2 plug and the CFexpress interface can be integrated into one unit via the first circuit board, ensuring the overall stability and compactness of the adapter board.

[0007] In some embodiments, the adapter board further includes a protective cover, which is fixedly disposed relative to the first circuit board or the CFexpress interface to form an accommodating space between the protective cover and the first circuit board or on the protective cover, capable of accommodating the CFexpress card, and a first opening that connects the CFexpress interface to the outside and allows the CFexpress card to enter and exit. Thus, the protective cover ensures the stability of the CFexpress card when inserted into the CFexpress interface.

[0008] In some implementations, the M.2 connector and the CFexpress interface are oriented parallel to each other and opposite to each other. This prevents interference between the disk reader connected to the M.2 connector and the CFexpress card connected to the CFexpress interface.

[0009] In some implementations, the length of the protective shield is not less than half the length of the CFexpress card. This ensures the stability of the CFexpress card 40 when inserted into the CFexpress interface 22.

[0010] In some embodiments, the side of the first opening of the protective cover is integrally formed or has a first notch. This facilitates the removal of the CFexpress card 40 from the receiving space 241 and the insertion of the CFexpress card 40 into the CFexpress interface 22 in the receiving space 241.

[0011] In some implementations, the M.2 connector has gold fingers to facilitate quick connection between the M.2 connector and the M.2 interface.

[0012] In some implementations, two sets of channels in the PCIe lanes of the M.2 connector are electrically connected to the CFexpress interface. This allows for maintaining high read speeds, for example, enabling CFexpress cards to achieve read speeds of up to 32 Gbps.

[0013] According to another aspect of this utility model, a disk reader with an adapter board is provided, which includes the aforementioned adapter board. Thus, when a CFexpress card needs to be read, the CFexpress card can be first inserted into the CFexpress interface of the adapter board, and then the M.2 connector of the adapter board can be inserted into a disk reader with an M.2 interface, so that the reading speed of the CFexpress card can reach 32G / s.

[0014] In some implementations, the disk reader with an adapter board also includes an M.2 interface and a data interface electrically connected to the M.2 interface. This allows data stored on a CFexpress card connected to the disk reader to be read via a connection to a computer through the data interface.

[0015] In some implementations, the data interface is a USB interface. This allows the data interface to be compatible with the vast majority of external devices.

[0016] In some embodiments, the disk reader with the adapter board also includes a base, on which at least one of the M.2 interface and the data interface is disposed. Thus, the base can support the M.2 interface and the data interface, ensuring the stability of the adapter board after it is connected to the M.2 interface.

[0017] In some implementations, the second opening of the M.2 interface is positioned facing away from the bottom of the base.

[0018] Therefore, when the bottom of the base is placed on the table, the second opening of the M.2 interface faces upwards, which facilitates the connection between the adapter board and the M.2 interface and ensures the stability of the connection between the adapter board and the M.2 interface. Moreover, when the M.2 plug and the CFexpress interface are parallel and opposite to each other, after the adapter board is connected to the M.2 interface, the third opening of the CFexpress interface also faces away from the bottom of the base, that is, the third opening of the CFexpress interface faces upwards, which facilitates the connection between the CFexpress card and the CFexpress interface of the adapter board and ensures the stability of the connection between the CFexpress card and the CFexpress interface.

[0019] In some implementations, the M.2 interface is located at the top of the base. This facilitates the connection between the adapter plate and the M.2 interface; moreover, when the second opening of the M.2 interface is positioned away from the bottom of the base, the stability of the connection between the adapter plate and the M.2 interface is ensured.

[0020] In some implementations, the data interface is electrically connected to the M.2 interface via a data cable. Therefore, when the disk reader is connected to an external device via the data interface, the flexibility of the data cable allows for diverse placement options for the disk reader's base.

[0021] In some embodiments, the disk reader with an adapter plate also includes a power switch for controlling the disk reader's on and off states, the power switch being mounted on the base. Thus, the disk reader can be controlled to turn on and off via the power switch. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Figures 1 to 4 The adapter plate according to the first embodiment of the present invention is shown schematically.

[0028] like Figure 2 As shown, the adapter board includes an M.2 plug 21, a first circuit board 23, and a CFexpress interface 22. The M.2 plug 21 and the CFexpress interface 22 are electrically connected to the first circuit board 23 so that the M.2 plug 21 and the CFexpress interface 22 can be electrically connected through the first circuit board 23.

[0029] When it is necessary to read the CFexpress card 40, the CFexpress card 40 can be inserted into the CFexpress interface 22 of the adapter board first, and then the M.2 connector 21 of the adapter board can be inserted into a disk reader or hard drive enclosure with an M.2 interface 31. Since the disk reader with the M.2 interface 31 has a faster reading speed than the disk reader with the CFexpress interface 22, this application enables the CFexpress card 40 to be read by the disk reader with the M.2 interface 31 through the adapter board, thereby increasing the reading speed of the CFexpress card 40 from 10G / s of the disk reader with the CFexpress interface 22 to 32G / s. Moreover, since this application integrates the M.2 connector 21 and the CFexpress interface 22 into one unit through the first circuit board 23, it also ensures the overall stability and compactness of the adapter board.

[0030] In some embodiments, such as Figure 3As shown, the adapter board also includes a protective cover 24, which is fixedly disposed relative to the first circuit board 23 or the CFexpress interface 22. A receiving space 241 capable of accommodating the CFexpress card 40 is formed between the protective cover 24 and the first circuit board 23, or on the protective cover 24. A first opening 242 connects the CFexpress interface 22 to the outside and allows the CFexpress card 40 to enter and exit, thereby ensuring the stability of the CFexpress card 40 when inserted into the CFexpress interface 22. In some preferred embodiments, the length of the protective cover 24 is not less than half the length of the CFexpress card 40 to ensure the stability of the CFexpress card 40 when inserted into the CFexpress interface 22. In some preferred embodiments, the side of the first opening 242 of the protective cover 24 is integrally formed or machined with a first notch 243, which can be arc-shaped or square, to facilitate the removal of the CFexpress card 40 from the receiving space 241 and the insertion of the CFexpress card 40 into the CFexpress interface 22 within the receiving space 241.

[0031] In some embodiments, such as Figure 1 and Figure 2 As shown, the M.2 plug 21 and the CFexpress interface 22 are parallel and opposite to each other to avoid interference between the disk reader connected to the M.2 plug 21 and the CFexpress card 40 connected to the CFexpress interface 22.

[0032] In some embodiments, such as Figure 2 and Figure 3 As shown, the M.2 plug 21 has gold fingers. In other embodiments, the M.2 plug 21 may also adopt other types of plugs commonly used in the prior art.

[0033] In some embodiments, the CFexpress interface 22 adopts the CFexpress interface 22 commonly used in the prior art. This application does not limit the specific implementation of the CFexpress interface 22.

[0034] In some embodiments, such as Figure 4 As shown, two sets of channels in the PCIe (peripheral component interconnect express) channel of the M.2 connector 21 are electrically connected to the CFexpress interface 22 to adapt the CFexpress interface 22 to the M.2 connector and maintain a high read speed.

[0035] As another implementation of the adapter board, compared with the first implementation of the adapter board, the adapter board in this implementation does not include the first circuit board 23, and the M.2 plug 21 is electrically connected to the CFexpress interface 22 in other ways. This implementation does not limit the electrical connection method between the M.2 plug 21 and the CFexpress interface 22.

[0036] Figures 5 to 9 The diagram schematically shows a disk reader with an adapter plate according to one embodiment of the present invention.

[0037] like Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the disk reader with an adapter board includes the aforementioned adapter board.

[0038] When it is necessary to read the CFexpress card 40, the CFexpress card 40 can be inserted into the CFexpress interface 22 of the adapter board first, and then the M.2 plug 21 of the adapter board can be inserted into the disk reader with the M.2 interface 31. Since the disk reader with the M.2 interface 31 has a faster reading speed than the disk reader with the CFexpress interface 22, this application enables the CFexpress card 40 to be read through the disk reader with the M.2 interface 31 through the adapter board, thereby increasing the reading speed of the CFexpress card 40 from 10G / s of the disk reader with the CFexpress interface 22 to 32G / s.

[0039] In some embodiments, such as Figures 5 to 9 As shown, the disk reader with an adapter board also includes an M.2 interface 31 and a data interface 32 electrically connected to the M.2 interface 31, so as to read data stored in the CFexpress card 40 connected to the disk reader by connecting to a computer through the data interface 32; moreover, the resulting disk reader can directly read hard drives with M.2 connectors 21 through the M.2 interface 31, and can also read CFexpress cards 40 with CFexpress connectors with the help of the adapter board, realizing multiple uses for one disk. In some embodiments, the data interface 32 is a USB interface, so that the data interface 32 is compatible with most external devices. In some embodiments, such as Figure 8 As shown, the disk reader with an adapter board also includes a second circuit board 36, through which the data interface 32 and the M.2 interface 31 are electrically connected. In some preferred embodiments, such as Figure 6 and Figure 8 As shown, the data interface 32 is electrically connected to the M.2 interface 31 via the data cable 34. When the disk reader is connected to an external device via the data interface 32, the flexibility of the data cable 34 allows for diverse placement options for the disk reader's base 33.

[0040] In some embodiments, such as Figure 5 , Figure 6 and Figure 9 As shown, the disk reader with the adapter board also includes a base 33, and at least one of an M.2 interface 31 and a data interface 32 is disposed on the base 33 to support the M.2 interface 31 and the data interface 32, ensuring the stability of the adapter board after it is connected to the M.2 interface 31. In some embodiments, such as Figure 6 As shown, the base 33 includes a detachably connected upper cover 331 and a lower cover 332, forming a receiving cavity 333 capable of accommodating the M.2 interface 31 when the upper cover 331 and the lower cover 332 are connected; the upper cover 331 has an integrally formed or machined through hole 3311 communicating with the outside of the M.2 interface 31, so as to provide physical protection for the M.2 interface 31 through the base 33. In some preferred embodiments, such as Figure 7 and Figure 8 As shown, at least one of the upper cover 331 and the lower cover 332 is integrally formed or machined with ventilation holes to facilitate heat dissipation from the M.2 interface 31. In some preferred embodiments, such as Figures 6 to 8 As shown, the base 33 also includes foot pads 334, which are connected to the bottom of the lower cover 332. The foot pads 334 are made of materials that can undergo elastic deformation, such as silicone or rubber, to provide cushioning and anti-slip effects for the base 33.

[0041] In some embodiments, such as Figure 5 , Figure 6 and Figure 9 As shown, the second opening 311 of the M.2 interface 31 faces away from the bottom of the base 33. When the bottom of the base 33 is placed on a table, the second opening 311 of the M.2 interface 31 faces upward, which facilitates the connection between the adapter board and the M.2 interface 31 and ensures the stability of the connection between the adapter board and the M.2 interface 31. Moreover, when the M.2 plug 21 and the CFexpress interface 22 are parallel and opposite to each other, after the adapter board is connected to the M.2 interface 31, the third opening of the CFexpress interface 22 also faces away from the bottom of the base 33, that is, the third opening of the CFexpress interface 22 faces upward, which facilitates the connection between the CFexpress card 40 and the CFexpress interface 22 of the adapter board and ensures the stability of the connection between the CFexpress card 40 and the CFexpress interface 22.

[0042] In some embodiments, continue to refer to Figure 5 , Figure 6 and Figure 9As shown, the M.2 interface 31 is located on the top of the base 33 to facilitate the connection between the adapter plate and the M.2 interface 31; moreover, when the second opening 311 of the M.2 interface 31 is set to face away from the bottom of the base 33, the stability of the connection between the adapter plate and the M.2 interface 31 can be guaranteed.

[0043] In some embodiments, such as Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the disk reader with an adapter board also includes a power switch 35 for controlling the disk reader's on and off states. The power switch 35 is mounted on the base 33 to control the disk reader's on and off states. In some embodiments, the power switch 35 is electrically connected to the M.2 interface 31 and the data interface 32 via a second circuit board 36 to control the connection and disconnection of the M.2 interface 31 and the data interface 32.

[0044] In this invention, the connection or installation is a fixed connection unless otherwise specified. A fixed connection can be implemented as a detachable or non-detachable connection commonly used in the prior art. A detachable connection can be implemented using existing technologies, such as threaded connections or keyed connections. A non-detachable connection can also be implemented using existing technologies, such as welding or adhesive bonding.

[0045] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
