Server chassis capable of decreasing radiation and server

Abstract

The present invention relates to a server chassis capable of decreasing radiation and a server. The server chassis is characterized in that the server chassis includes a chassis, a small board and a main board; the small board is provided with a VGA connector and USB connectors; the chassis comprises a metal case and a front plastic case; a VGA opening for matching the VGA connector on the small board, USB openings for matching the USB connectors on the small board, and mounting holes are formed in the front plastic case; conductive fixing components can be plugged into the mounting holes in amatched manner, so that the small board can be installed on the front plastic case; fixing holes corresponding to the mounting holes of the front plastic case are formed in the small board; the conductive fixing components are plugged into the mounting holes and the fixing holes, so that the small board can be installed on the front plastic case; the front plastic case is subjected to conductivespraying treatment; and the metal case is fixedly connected with the front plastic case.

Description

technical field [0001] The invention belongs to the technical field of server design, and in particular relates to a server case and a server capable of reducing radiation. Background technique [0002] In the server, there are usually VGA (Video Graphics Array, video image array) and USB (Universal Serial Bus universal serial bus) interface devices, and the VGA and USB interfaces can be connected to external display devices and USB devices to realize the expansion of external functions . [0003] In the design of the server, in order to be beautiful and cost-saving and to meet the requirements of customers, the server’s front case is composed of plastic parts. If there is no good design, the VGA and USB inside the plastic case will be grounded, which is equivalent to the front connection. A very long antenna was installed to directly transmit the radiation signal into space, causing strong radiation interference. [0004] The cables connected inside the server are wrapped...

Problems solved by technology

[0003] In the design of the server, in order to be beautiful and cost-saving and to meet the requirements of customers, the server’s front case is composed of plastic parts. If there is no good design, the VGA and USB inside the plastic case will be grounded, which is equivalent to the front connection. A very long antenna is installed to directly transmit the radiation signal into the space, causing strong radiation interference

[0004] The cables connected inside the server are wrapped with conductive cloth or copper tape for electromagnetic shielding. Disadvantages of this method ① After the cable is wrapped with the shielding layer, the cable is relatively hard as a whole, and it is not easy to bend, which affects assembly and occupies the server. Overall internal use space

② After the cable wraps the shielding layer, the overall width becomes thicker. When the cable is long, it is difficult to thread it inside the server

③The cost is relatively high. Under the same conditions, the waste of shielding materials increases the overall cost of the product
