[0002] The Mini-Compression Storage Disk Module (mCSDM) and the (standard-size) Compression Storage Disk Module (CSDM) are next-generation storage hard drive modules, primarily connected via board-to-board connectors.

[0003] Compression storage hard drive modules are the next generation of storage hard drive technology. High-speed reading and writing is one of its key parameters. Testing the reading and writing speed requires lossless and stable connection to the test equipment.

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. The accompanying drawings show preferred embodiments of the present invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] Unless otherwise specified, various raw materials, instruments and equipment used in the present invention can be purchased from the market or prepared by existing methods.

[0028] Figure 1 This is a main view of a compression solid-state storage hard disk module test device based on the M.2 interface provided by the embodiment of the utility model. Figure 1 As shown, the compressed solid-state storage hard disk module testing device based on the M.2 interface includes a circuit board 1, an adjustment and fixing component 2, a board-to-board connector 3 and a mounting base 4; the circuit board 1 is an M.2 2280 circuit board 1, and the circuit board 1 is provided with an M.2 interface 6 for high-speed communication with the CPU; the board-to-board connector 3 and the mounting base 4 are respectively arranged on the same surface (for example, the front surface or the top surface) of the circuit board 1; wherein, the board-to-board connector 3 is electrically connected to the circuit board 1, and the compressed solid-state storage hard disk module to be tested is positioned and placed on the board-to-board connector 3; the adjustment and fixing component 2 is hinged on the mounting base 4, and the adjustment and fixing component 2 is used to press and fix the compressed solid-state storage hard disk module on the board-to-board connector 3.

[0029] In the embodiment of the present invention, the compression storage hard disk module may be, for example, a micro compression storage hard disk module, a standard-size compression storage hard disk module, an expandable compression storage hard disk module, and the like.

[0030] Figure 2 yes Figure 1 Side view in the AA direction, see Figure 2 As shown, the mounting base 4 is a step structure, wherein the mounting base 4 includes an upper step and a lower step arranged from high to low, and a chamfered press avoidance groove 40 is provided on one side of the upper step close to the lower step, and the press avoidance groove 40 is used to provide an avoidance space when installing the adjustment and fixing component 2.

[0031] The adjusting and fixing assembly 2 includes a pressing member 21, a pressing plate member 22 and a return spring 23. The middle area of ​​the pressing member 21 is hinged to the pressing avoidance groove 40 through a first latch 24. The pressing member 21 is fixedly connected to the return spring 23 near the bottom of the lower step. The other end of the return spring 23 is fixedly connected to the lower step. The end of the pressing member 21 away from the return spring 23 is hinged to the pressing plate member 22 through a second latch 25. The pressing plate member 22 faces the board-to-board connector 3. The pressing member 21 is hinged to the pressing member 21 through the first latch 24. A lever structure is formed at the pressure avoidance groove 40, and pressure is applied to the pressing member 21 to rotate around the first pin 24 as the axis. At this time, the pressure plate 22 is tilted, so that the compressed solid-state storage hard disk module can be placed. After the compressed solid-state storage hard disk module is accurately positioned and placed on the board-to-board connector 3, the pressure applied to the pressing member 21 is stopped.

The spring needle 33 and the positioning column 31 cooperate with the positioning hole (or positioning plate groove) of the compressed solid-state storage hard disk module to form precise positioning, thereby achieving stable connection; since the positioning holes (or positioning plate grooves) for installation and positioning of compressed storage hard disk modules of different specifications such as micro compressed storage hard disk modules, standard size compressed storage hard disk modules and extended type compressed storage hard disk modules are consistent, compatible positioning of multiple versions can be achieved.

[0034] In an embodiment of the present invention, an avoidance gap 9 is formed at the setting position between the board-to-board connector 3 and the adjustment and fixing component 2, so as to provide an avoidance area when the compressed solid-state storage hard disk module is fixed, thereby improving the flexibility during installation, so that it can be suitable for compressed solid-state storage hard disk modules of different specifications; at the same time, the area where the avoidance gap 9 is located can also be used to place decoupling filter capacitors to improve the power supply quality.
