Description

Shielding device and housing

The present invention relates to a shielding device, in particular to a shielding device for shielding an opening of a server casing.

With the rapid development of technology, the functions and integration of servers are becoming higher and higher. Therefore, the number of electronic components supported in the internal space of the server is also increasing day by day, and electronic components can be increased or decreased according to demand. In order to make the server expandable and convenient for operators to increase or decrease the electronic components installed in the server, openings are usually set on the server casing for the installation of electronic components.

In order to prevent dust from entering the pre-reserved openings, which would cause the circuits between electronic components to come into contact with dust and thus have poor contact, operators generally install covers to cover the openings on the server casing. However, due to the large number of electronic components inside the server, the space inside the server is small, which makes it easy for operators to cause the cover to shift multiple times when assembling it, thereby increasing the assembly time. In the narrow internal space of the server, additional limiter components are added to limit the cover, which will make the internal space of the server even smaller and increase the assembly cost. Therefore, how to reduce the number of times the cover is shifted on the server casing, save assembly space, and reduce assembly costs is one of the problems that R&D personnel should solve.

The present invention provides a shielding device to reduce the number of times a cover plate is assembled on a server housing, save assembly space and reduce assembly cost.
