A low-radiation installation structure for server front cables

Abstract

The present application discloses a low-radiation mounting structure of a server front wire cable which comprises a server box body made of metal materials, a front housing is mounted on one end of the server box body, a port circuit board is installed in the front housing, the port circuit board is connected to a main board mounted on the box body via a flat cable, an outer surface of the flat cable is provided with an electric cable shielding layer used for covering the flat cable, and the port circuit board and the server box body are electrically connected through the electric cable shielding layer. In the low-radiation mounting structure disclosed in the present application, the port circuit board and the server box body are electrically connected through the electric cable shieldinglayer to ensure that a differential mode current generated via the port circuit board in the front housing can flow back to the server box body, and then differential mode current can flow back to theearth through the server box body, radiation interference is prevented, and overall radiated emission energy is reduced.

Description

technical field [0001] The present application belongs to the technical field of servers, and in particular relates to a low-radiation installation structure of front cables of servers. Background technique [0002] In the field of servers, VGA (Video Graphics Array, video image array) and USB (Universal Serial Bus) interface devices are usually provided. The VGA and USB interfaces can be connected to external display devices and USB devices to realize the expansion of external functions. . [0003] Solving the problem of electromagnetic radiation has always been a difficult problem in the server field. The common method is to make the chassis a shield, and try not to use plastic parts. However, using all metal parts will affect the overall appearance design of the product, and the cost is high. Therefore, plastic parts are generally used to make the front shell. Because the cable has a long radiation path, it will generate high radiation, and a complete shield is required...

Problems solved by technology

However, using all metal parts will affect the overall appearance design of the product, and the cost is high. Therefore, plastic parts are generally used to make the front shell. Because the cable has a long radiation path, it will generate high radiation, and a complete shield is required to shield the radiation source. However, in order to ensure the cost and appearance requirements of the server, the front shell must also be made of plastic parts. Therefore, we can only increase the test limit and relax the overall design requirements. In the industry, the radiation test limit of servers is generally relaxed to A level, and the test limit of daily electronic products is usually B level. However, doing so will increase large overall radiant emission energy
