On the other hand, when the user wants to assemble the movable tray 23 back into the module accommodating slot SA in the fixing frame 21, he only needs to insert the movable tray 23 into the module accommodating slot SA along the direction opposite to the extraction direction, At this time, the abutting inclined surface 2711 of the latching protrusion 271 abuts against the fixing frame 21 , so that the operating portion 272 is gradually deformed along the stress direction DF and stores an elastic deformation force. When the movable carrier plate 23 moves in the direction opposite to the extraction direction DA until the abutting slope 2711 of the latching protrusion 271 no longer contacts the fixing frame 21 and is completely located on the side of the latching hole 211 , the operation part 272 releases the elastic deformation force to release the elastic deformation force. Reset in the direction opposite to the force direction DF, make the buckle protrusion 271 pass through the buckle hole 211, and make the surface of the fixing frame 21 around the buckle hole 211 block the stop surface 2712 of the buckle protrusion 271 to restrict The displacement of the snap protrusions 271 in the extraction direction DA completes the assembly of the movable tray 23 .

In the present embodiment, the movable carrier plate 23 is fixed to the fixing frame 21 through the elastic clips 27, but the present invention is not limited to this. In other embodiments, the movable carrier plate can be fixed to the fixing frame by other fixing means such as quick release screws or tenons.

In this embodiment, the accommodating space 212 of the fixing frame 21 of the M.2 interface module 2 has two module accommodating slots SA, which can accommodate two sets of movable carriers with the M.2 interface expansion card 25 installed. disc 23, but the present invention is not limited to this. In other embodiments, the accommodating space of the fixing frame can be designed, for example, to have one or more than three module accommodating slots for accommodating one or more than three groups of movable loaders equipped with M.2 interface expansion cards. plate.

According to the M.2 interface module and the server including the M.2 interface module of the above-mentioned embodiments, the opening and the accommodating space of the fixing frame of the M.2 interface module are exposed by disposing through holes in the case shell, so that the M.2 interface module is installed with the M.2 interface module. .2 The movable carrier plate of the interface expansion card can be directly inserted into the module accommodating slot of the accommodating space through the opening of the fixing frame, and can be directly taken out from the module accommodating slot through the opening of the fixing frame without disassembling the case The M.2 interface expansion card can be repaired or replaced only after the housing or the entire M.2 interface module is removed, allowing users to repair or replace the M.2 interface expansion card of the server more easily.

In addition, since the accommodating space of the fixing frame is connected to the outside through the through holes of the case shell, and the fixing frame can be provided with a plurality of ventilation holes, the M.2 interface module can be well ventilated, which is beneficial to M.2 interface expansion card cooling.

In addition, the M.2 interface module is provided with an elastic buckle that can be operated without hand tools, and through the buckle protrusions that pass through the buckle holes of the fixing frame, the module that can fix the movable tray in the accommodating space can be accommodated. On the other hand, by moving the operating portion from the buckled position to the unlocked position, the buckle convex portion is separated from the buckled hole of the fixing frame, and the movable tray can be withdrawn from the fixing frame. Thereby, hands-free tool disassembly and assembly is realized.

Although the present invention is disclosed by the above-mentioned preferred embodiments, it is not intended to limit the present invention. Anyone who is familiar with the similar arts can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, this The scope of patent protection of the invention shall be determined by the scope of the patent application attached to this specification.
