Description

Shielding device and housing

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

With the rapid development of technology, the functions and integration of servers are getting 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 in terms of electronic components and to facilitate 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, causing the circuits between electronic components to contact the dust and cause poor contact, generally speaking, operators will set up 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, 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 assembly 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, thereby reducing the number of deviations of the assembly cover on the server casing, saving assembly space and reducing assembly costs.

The two side frames and the connecting frame are respectively located on different sides of the opening of the casing. The two side frames and the connecting frame together surround a storage space. The opening is connected with the accommodation space. The receiving frame body includes at least one convex hull structure. At least one convex bulge structure protrudes from one of the two side frames and is partially located in the accommodation space. The cover has two side surfaces and at least one guide groove. The two sides face away from each other. At least one guide groove is located on one of the two side surfaces. At least one convex structure is located on at least one guide groove to guide the cover to be disposed in the accommodation space and to cover the opening of the casing.
