Background technique

Due to the limitation of the internal space of the mini computer system and the need to enhance the convenience of assembly, its various storage components (such as hard drives, optical drives, etc.) will adopt a modular design concept, and use an interface card (Riser Card) to connect each The power supply and electronic signal of the storage component are used to form a storage component module (Storage Device Module). Generally speaking, the mini computer system includes a top cover, a storage component module pre-fixed inside the top cover, a bottom plate, and a system body pre-fixed on the bottom plate.

When the computer system needs to be assembled, it only needs to cover the storage component module on the system body, and insert the interface card of the storage component module into the slot (Socket) of the system body at the same time.

The storage component module 12 includes a bracket 121 fixed on the upper cover 11 , and at least one storage component 122 and an interface card 123 fixed on the bracket 121 .

However, when the components 121, 122, 123 of the storage component module 12 are assembled with screws and the bracket 121 is assembled on the upper cover 11, the dimensional tolerance of each component 121, 122, 123 is the same as the assembly tolerance caused by the aforementioned assembly. The accumulation will cause the offset of the interface card 123 .

Therefore, when the storage component module 12 is assembled on the system body 14, the offset caused by the aforementioned tolerance will cause the position of the interface card 123 of the storage component module 12 to shift, so that the interface card 123 cannot be inserted into the slot 141 or inserted obliquely. In the slot 141 , the transmission of electronic signals is affected, which further causes the failure of the computer system 1 .
