When the anti-mistake groove 26 corresponds to the correct direction, the tray 20 can be inserted into the slot space 11 of the tray housing 10.

The extraction member 30 is a component provided for the user to hold in hand, so that the user can insert and remove the above-mentioned tray 20. The extraction member 30 is preferably implemented as a block assembled at the rear end of the tray 20, which can be formed by stamping and bending an aluminum alloy plate, or a plastic part formed by integral injection molding. A first locking portion 31 (which may be a sheet, etc.) protrudes from any side of the extraction member 30, and the first locking portion 31 forms a screw through hole so that a screw 32 can be passed through the first locking portion 31. The first locking portion 31 can be locked to a second locking portion 17 protruding from one side of the rear end of the tray housing 10 (as shown in Figures 1 and 6) or to the back panel 80 of the computer (as shown in Figures 8 and 9). One of the preferred assembly embodiments is shown in FIG3 . The rear end of the tray 20 is provided with a latch hole 23, screw through holes 24 on both sides of the latch hole 23, and a fixing screw 25 that can pass through the screw through hole 24; and the corresponding front end of the extraction member 30 is provided with a latch protrusion 33 that can be embedded in the latch hole 23, and a locking portion 34 (locking hole) corresponding to the screw through hole 24, so that the fixing screw 25 can be locked in the locking portion 34, thereby assembling the extraction member 30 at the rear end of the tray 20.

Referring to FIG. 3 and FIG. 4 , the tray cover 40 is preferably formed by stamping and bending an aluminum alloy plate, so that it can be used to detachably cover the hard disk storage space 21 of the tray 20, and enclose the M.2 solid state drive 300 in the hard disk storage space 21. The tray cover 40 is implemented as a rectangular sheet corresponding to the tray 20, and an elastic pressing sheet 41 is formed at one end corresponding to the front end of the tray 20. A buckle sheet 42 is bent on both sides of the elastic pressing sheet 41, and the buckle sheet 42 is used to buckle with the buckling parts 52 on both sides of the tray 20 (as shown in FIG. 1 ). The tray cover 40 is provided with a coupling portion 43 at the other end corresponding to the rear end of the tray 20. The coupling portion 43 has a screw through hole, and the coupling portion 43 is fixed to the bottom surface of the extraction member 30 or the tray 20 by a screw 44. The elastic pressing piece 41 can be formed by punching an L-shaped groove 45 or other shapes of grooves on both sides of the tray cover 40. In order to facilitate the tray cover 40 to be correctly installed on the tray 20, the bottom surfaces of the two side walls 22 of the tray 20 are respectively provided with an embedding groove 27, and the embedding groove 27 extends to the two ends of the side wall 22; and the two sides of the tray cover 40 are respectively bent with an embedding piece 46, and the embedding pieces 46 and the buckle piece 42 on both sides are respectively embedded in the embedding groove 27 of the side wall 22 during assembly, and the buckle piece 42 is buckled in the buckling part 52 located in the embedding groove 27 (as shown in Figure 1).

The back plate 80 is also provided with a third locking portion 83 corresponding to the first locking portion 31 of the extraction member 30. The third locking portion 83 can be a locking hole. The circuit board 100 is usually a motherboard, which is fixed on a tray 401 in the case 400 (as shown in FIG. 6 ), and a known M.2 connector 200 is packaged on the circuit board 100. When the circuit board 100 and the backplane 80 are installed, the hard drive plug hole 81 of the backplane 80 is aligned with the M.2 connector 200.

Referring to FIG. 7 , when the plug-in piece 121 of the plug-in pin 12 of the tray housing 10 of the present invention is respectively inserted into the plug-in hole on the circuit board 100, the supporting portion 13 on the plug-in piece 121 can be against the surface of the circuit board 100, so that the front end of the slot space 11 of the tray housing 10 is aligned with the M.2 connector 200, and the rear end of the slot space 11 is aligned with the hard disk plug-in hole 81 of the back plate 80. With this assembly structure, a heat dissipation space A1 is formed between the bottom surface of the tray housing 10 and the surface of the circuit board 100, so that electronic components can be added to this space, and poor heat dissipation of electronic components on the circuit board 100 can be avoided, and the M.2 solid state hard disk 300 can also be effectively cooled.

After an M.2 solid state hard disk 300 is arranged in the hard disk accommodating space 21 of the tray 20, the gold finger portion 301 of the M.2 solid state hard disk 300 passes through the end cover 50 and protrudes from the front end of the tray 20, and the first anti-fouling protrusion 51 of the end cover 50 is locked in the recess 302 of the gold finger portion 301. When the user holds the extraction member 30, the front end of the tray 20 can be inserted into the slot space 11 of the tray housing 10 through the hard disk insertion hole 81 of the back plate 80 until the gold finger portion 301 of the M.2 solid state hard disk 300 is plugged into the M.2 connector 200, and then the screw 32 of the first locking portion 31 of the extraction member 30 is directly locked to the second locking portion 17 of the tray housing 10 (as shown in Figures 1 and 6), or the screw 32 of the first locking portion 31 is locked to the third locking portion 83 of the back plate 80 (as shown in Figures 8 and 9), thereby completing the plug-in assembly structure of the M.2 solid state hard disk 300. On the contrary, after removing the screw 32 of the extraction member 30, the extraction member 30 can be grabbed and pulled out in the reverse direction, so that the M.2 solid state drive 300 is separated from the M.2 connector 200, achieving the function of quick plug-in and replacement.
