A boss one is arranged in the middle of the upper side of the fixed installation part, and the boss one extends to a side away from the shielding part. The extension of the boss one Threaded holes are provided; the middle part of the upper side of the shielding part is provided with boss 2, and two processor interface through holes are arranged on the boss 2; memory installation slots are arranged at the flanges on both sides of the shielding part in the length direction; The width is smaller than the width of the shielding portion. The width of the clamping installation part is reduced to ensure that the shielding cover is easy to install and disassemble.

Preferably, grooves are provided on both sides of the shielding portion near the clamping installation portion, and reinforcing ribs are provided in the grooves.

More preferably, the clamping installation part is in the shape of a "convex".

Compared with the prior art, a shielding cover for preventing the electromagnetic interference of the storage controller of the utility model has the following beneficial effects:

1. The utility model can solve the problem that in the design of the storage controller, the electronic components such as the processor and the memory are placed together, causing mutual electromagnetic interference, causing the electronic components to fail to work normally, and the failure rate is high. The shielding part of the shielding cover will The processor and memory are isolated to prevent mutual influence between the two and ensure that electronic components can work normally;

2. By setting a plastic transparent shield, it not only realizes the isolation of the processor and the memory, effectively prevents electromagnetic interference, but also improves the cleanliness and aesthetics of the storage controller;

3. The fixed installation part of the shielding cover is fixedly connected by screws, the shielding part is connected by the flanges on both sides, and the clamping installation part is fitted by the peripheral flanges, so the installation and disassembly of the shielding cover is convenient;

It can be seen that the utility model has the characteristics of reasonable design, simple structure, easy processing, small volume, convenient use, multi-purpose, etc. Therefore, it has good promotion and use value.
