Description

Technical Field

[0001] The present application relates to the field of electronic component interface conversion, and in particular to a solid-state hard disk adapter board and a solid-state hard disk assembly. Background Art

[0002] A solid-state drive is a module device with functions such as storing, reading, and writing electronic data. It is electrically connected to the controller, cache chip, and flash memory chip on the PCB board and works together. Common interfaces for solid-state drives on the market include M.2, SATA, U.2, SAS, PCIe, etc. Intel proposed the concept of EDSFF in 2018 to redefine the next-generation solid-state drive form factor for servers. The Storage Networking Industry Association (SNIA) subsequently proposed the SFF-TA-1008 specification, which includes E1.S, E1.L, E3.S, E3.S2T, E3.L, E3.L2T and other new storage module form factor standards. After several years of market selection, the most promising and most commonly used form factor standard in the industry is E3.S. Compared with the previous U.2 interface solid-state drives, E3.S has the characteristics of high density, high capacity, low latency, and excellent signal integrity, and is a more promising standard. In the latest generation of storage module transmission standard, PCIe 5.0, E3.S products are gradually being used.

[0003] However, this E3.S interface can only be applied to a small number of newly designed servers, while the consumer and personal ends, such as desktops and network attached storage (NAS), are not yet compatible with the E3.S interface. How to be compatible and apply E3.S is still a problem. Also, because E3.S is a new standard appearance and new interface that was just launched in 2018, there is a lack of ready-made adapter board solutions in the existing technology.

[0004] For example, the Chinese invention patent with the announcement number "CN113741649A" discloses "a hot-swappable adapter module". This invention patent only uses an adapter plate to limit and transfer the M.2 hard drive. Therefore, many existing adapter plate solutions still focus on the design of common interfaces such as PCIe to M.2 or PCIe to U.2. Utility Model Content

DETAILED DESCRIPTION

[0027] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.

[0028] See also Figures 3 to 5 The embodiment of the utility model is to design a solid state drive adapter board, which includes a PCB board 1 and a support frame 5. The support frame 5 can be equipped with a solid state drive 6, and the support frame 5 allows the solid state drive 6 to be fixed relative to the PCB board 1. The PCB board 1 includes a PCIe gold finger 9 and an E3.S female end interface 4, and the PCB board 1 also includes a trace 11 that electrically connects the PCIe gold finger 9 to the E3.S female end interface 4. The trace 11 is a part of the printed circuit of the PCB board 1. Among them, the PCB board 1 is a printed circuit board. The PCIe gold finger 9 forms a PCIe interface, and PCIe is the abbreviation of Peripheral Component Interconnect Express, which is a high-speed serial computer expansion bus standard. E3.S is a standard solid state drive (SSD) size specification, and its size is 76mmx104.9mm, and the thickness has two options of 7.5mm and 16.8mm. The size of E3.S is the result of optimization for NAND flash memory (a type of flash memory). E3.S can accommodate at least 1.5 times the storage capacity of the U.2 specification. The "gold finger" of the PCIe gold finger 9 can be composed of a number of golden conductive contacts, which are called "gold fingers" in the field of computer hardware because of their gold-plated surface and finger-like arrangement of the conductive contacts. An E3.S male interface is protruded on one end of the solid-state drive 6, and the E3.S male interface and the E3.S female interface 4 can be mutually plugged and assembled and electrically connected.

[0029] The speed protocol of the E3.S female interface 4 is PCIe Gen5 with a theoretical peak transmission speed of 32GT / s. The E3.S female interface 4 can also adapt to Gen6, Gen7, etc. The solid-state drive 6 can be an E3.S2T solid-state drive, that is, the storage capacity is 2TB. Among them, Gen5 is the fifth-generation interface standard, and its theoretical peak transmission speed is 32GT / s (that is, 3.2 billion transmissions per second), which is a performance improvement over the previous fourth-generation standard Gen4. Gen6 and Gen7 are the sixth and seventh generation interface standards respectively. Compared with Gen5, Gen6 and Gen7 can further improve the data transmission speed and bandwidth. The transmission speed of Gen6 is 64GT / s, and the transmission speed of Gen7 is 128GT / s.

[0030] In another embodiment, if Figure 3 As shown, the PCB board 1 also includes a voltage conversion module 2 and an LED indicator module 3. The voltage conversion module 2 is used to control the input voltage within a reasonable range, and the LED indicator module 3 uses flashing lights to indicate the power-on state and the operating state. Figure 3 As shown, the voltage conversion module 2 and the LED indicator light module 3 can be both located on the PCB board 1 on the same side of the solid state drive 6 .

[0031] In another embodiment, if Figure 6 As shown, the PCB board 1 also includes a power switch control module 12 and an external power supply module 13. Figure 3 and Figure 4 , Figure 6 The switch control module 12 and the external power supply module 13 are shown. The power switch control module 12 plays the role of switching on and off the power according to the demand, and the external power supply module 13 supplies power to the PCB board 1. The external power supply module 13 can also have the protection functions of over-current, over-heating and short-circuit.

[0032] In another embodiment, if Figure 4 As shown, the PCIe gold finger 9 protrudes from one side edge of the PCB board 1, and the E3.S female end interface 4 and the PCIe gold finger 9 are located on the same side of the centroid X of the PCB board 1. Figure 4 The centroid X of the PCB board 1 is schematically shown in FIG. 1 , where the E3.S female interface 4 and the PCIe gold finger 9 are both Figure 4 The lower side of the centroid X.

[0033] The beneficial effect of adopting the above embodiment is that the E3.S female interface 4 and the PCIe gold finger 9 can be arranged closer, which can reduce the distance of the trace 11 in the PCB board 1 and reduce the wiring difficulty of the trace 11.

[0034] In another embodiment, if Figure 1As shown, the support frame 5 includes a bottom plate 51, a pair of side plates 52 vertically extend from both sides of the bottom plate 51, and a top plate 53 extends from one side of the pair of side plates 52 away from the bottom plate 51; the support frame 5 has a plurality of hanging plates 55, and the hanging plates 55 are assembled with the PCB board 1; the bottom plate 51, the side plates 52, and the top plate 53 of the support frame 5 form a semi-wrapped limit for the solid state drive 6. The bottom plate 51, the side plates 52, and the top plate 53 of the support frame 5 are in a state of being vertically connected in sequence, and the sum of the widths of the two top plates 53 is also smaller than the width of the bottom plate 51.

[0035] The beneficial effect of adopting the above embodiment is: a bottom plate 51, two side plates 52, and two top plates 53 constitute a symmetrical and semi-enclosed support frame 5, with the bottom plate 51 being in contact with one side of the solid-state hard disk 6, and the two side plates 52 correspondingly clamping the two sides of the solid-state hard disk 6, so that the support frame 5 can form a semi-enclosed limit for the solid-state hard disk 6.

[0036] In another embodiment, if Figure 1 As shown, the facing surfaces of a pair of side plates 52 are both affixed with buffer pads 7 , and the two buffer pads 7 are in contact with the outer wall of the solid state hard disk 6 to form a clamping limit.

[0037] The beneficial effect of adopting the above embodiment is that the buffer pad 7 acts as a buffering middle layer, thereby reducing the hard contact between the support frame 5 and the solid state hard disk 6, and reducing the probability of the solid state hard disk 6 being damaged due to bumps.

[0038] In another embodiment, if Figure 1 As shown, the hanging plates 55 on the same side of the support frame 5 extend in the same direction, and the hanging plates 55 on both sides of the support frame 5 extend in opposite directions. The extension direction of the hanging plates 55 is parallel to the plane where the bottom plate 51 is located. Figure 1 As shown, the number of the hanging plates 55 can be four. Figure 4 As shown, the number of the hanger plates 55 may be equal to the number of the fixing holes 8 on the PCB board 1 , that is, each hanger plate 55 is connected to a fixing hole 8 .

[0039] like Figure 2 As shown, the root of the hanging plate 55 is located at the junction of the bottom plate 51 and the side plate 52, and the side plate 52 is provided with a through hole 56. The hanging plate 55 is cut and bent from the support frame 5 at the location of the through hole 56. The outline of the hanging plate 55 is consistent with the outline of the through hole 56, and the outline of the through hole 56 can be rectangular.

[0040] The beneficial effect of adopting the above embodiment is that the shape and structure of the support frame 5 are conveniently obtained by bending and stamping a metal plate, which can reduce the manufacturing cost of the support frame 5.

[0041] In another embodiment, the buffer pad 7 is made of foam material, and the buffer pad 7 covers the through hole 56 .

[0042] The beneficial effect of the above embodiment is that the buffer pad 7 covers the through hole 56, which can ensure that the side of the solid state drive 6 is softly protected by the buffer pad 7. The side plate 52 can be used to elastically clamp the solid state drive 6 with the help of the buffer pad 7.

[0043] In another embodiment, if Figure 2 As shown, a circular tube portion 57 is integrally protruded from the surface of the hanging plate 55, and a through hole 58 is provided inside the circular tube portion 57; the PCB board 1 is provided with a fixing hole 8, one side of the hanging plate 55 forms a surface contact with the PCB board 1, and the circular tube portion 57 is positioned and assembled with the fixing hole 8. The axis extension direction of the circular tube portion 57 can be opposite to the protrusion direction of the side plate 52 from the bottom plate 51.

[0044] The beneficial effect of adopting the above embodiment is that the shape of the circular tube portion 57 is also easy to be deformed by punching the metal support frame 5. After the support frame 5 and the PCB board 1 are actually assembled, the axis of the circular tube portion 57 of the hanging plate 55 coincides with the axis of the fixing hole 8, and the fixing can be achieved by simultaneously passing through the through hole 58 of the circular tube portion 57 and the fixing hole 8 with fasteners such as screws. It is also possible to use the outer wall of the convex circular tube portion 57 to directly interfere with the inner wall of the fixing hole 8 without using external fasteners, which is more convenient.

[0045] In another embodiment, if Figure 4 , 5 As shown, one side edge of the PCB board 1 is provided with an inner notch 10; the shape surrounded by the inner notch 10 is a rectangle. Observing in a direction perpendicular to the plane of the PCB board 1, only the hanging plate 55 in the support frame 5 intersects with the PCB board 1, and only the E3.S male interface in the solid state drive 6 intersects with the E3.S female interface 4 of the PCB board 1.

[0046] The beneficial effect of adopting the above embodiment is: without affecting the stability of the support frame 5 and the PCB board 1 after being fixed, excessive compression contact between the PCB board 1 and the bottom plate 51 of the support frame 5 can be avoided, and the support frame 5 can be prevented from wearing the components on the surface of the PCB board 1.

[0047] In another embodiment, if Figure 1 As shown, the width of the side plate 52 is not less than the thickness of the solid state drive 6, and the width of the top plate 53 is less than the width of the side plate 52. The distance from one side of the PCB board 1 with the PCIe gold finger 9 to the other side of the PCB board 1 is the width of the PCB board 1, and the distance from one end of the solid state drive 6 with the E3.S male connector to the other end of the solid state drive 6 is the length of the solid state drive 6. The width of the PCB board 1 is less than the length of the solid state drive 6. Figure 4 , Figure 5 As shown, the length of the support frame 5 is smaller than the length of the solid state hard disk 6 .

[0048] The beneficial effects of adopting the above embodiment are: first, the shape and size of the support frame 5 are determined to ensure that the support frame 5 can adapt to the outer dimensions of the solid state drive 6. Second, the PCB board 1 is controlled within a smaller size, which can also be said that the PCB board 1 can adapt to a larger size of the solid state drive 6 with the help of the support frame 5.

[0049] In another embodiment, if Figure 1 As shown, the bottom plate 51 of the support frame 5 has a hollow hole 54 in the middle. Figure 5 As shown, the outer wall of the solid state drive 6 is provided with a reinforcing rib 61, and the top of the reinforcing rib 61 is in contact with the bottom plate 51. This further saves the material of the support frame 5, and the solid state drive 6 with the reinforcing rib 61 also improves its own structural strength.

[0050] The present application also provides a solid-state hard disk assembly, which includes: a solid-state hard disk adapter board according to the present application; and a solid-state hard disk 6, the solid-state hard disk 6 is installed on a support frame 5, and the E3.S male interface of the solid-state hard disk 6 is plugged into the E3.S female interface 4.

[0051] The above embodiments are only for illustrating the technical concept and features of the present application, and their purpose is to enable people familiar with this technology to understand the content of the present application and implement it. They cannot be used to limit the scope of protection of the present application. All equivalent changes or modifications made according to the spirit of the present application should be included in the scope of protection of the present application.
