Background technique

With the advancement of technology, the server has played an indispensable role in today's technology field, and with the improvement of functions and usage requirements, the amount of data stored in the server is also increasing day by day, so the server chassis usually needs Configure multiple hard disks to effectively increase the data storage capacity of the server. The hard disk configured in the chassis usually communicates with the motherboard through cables.

Generally speaking, the larger the space inside the server case, the more accessories it can accommodate, that is, the better the expansion performance. Therefore, designers often spend a lot of effort to maximize the use of limited space. However, in the prior art, a large number of cables are often used to connect the motherboard to the hard disk. However, when the number of hard disks required to be configured in the server increases, the cables configured therefor also need to increase accordingly, which is quite inconvenient for subsequent operations (such as assembling, testing, or disassembling and repairing hard disks, etc.). Furthermore, too many cables can easily affect the convection in the chassis, which will also have a great impact on the heat dissipation inside the chassis.

Therefore, how to design a hard disk module to avoid the above-mentioned disadvantages is an urgent problem to be solved at present.
