Abstract

The invention discloses an anechoic-chamber multi-optical-fiber waveguide tube. The waveguide tube includes a waveguide tube outer-ring, a waveguide tube fixing body, a waveguide tube connection screwrod, optical-fiber perforation holes, a bolt, a nut, a bottom post and a baffle body. The waveguide tube fixing body is inserted inside the waveguide tube outer-ring in a perforation manner. The waveguide tube connection screw rod is inserted inside the waveguide tube fixing body in a perforation manner. The six optical-fiber perforation holes are evenly arranged on the waveguide tube connectionscrew rod. The baffle body is arranged at the center of the bolt. The bolt is arranged on top of the baffle body. The nut is arranged at the top of the bolt. The bottom post is also arranged at the bottom end of the baffle body. A device of the invention is the anechoic-chamber multi-optical-fiber waveguide tube. According to the device, sizes of optical fiber are exactly the same as sizes of theholes, a sealing effect is good, and shielding performance is not impacted; and an optical-fiber line is divided into six optical-fiber lines, thus a gap generated by each optical-fiber line and a hole is very small, and a shielding effect is improved.

Description

technical field

[0001] The invention relates to a waveguide, in particular to a multi-channel optical fiber waveguide in an electric wave anechoic chamber, belonging to the technical field of electromagnetic shielding. Background technique

[0002] The basic principle of the shielded computer room comes from the Faraday cage design. In the absence of shielding, our electronic equipment will be affected by strong electromagnetic interference sources such as direct lightning or indirect lightning, which will cause the equipment to fail to work or work abnormally. In the worst case, it will be damaged. This is a relatively common manifestation of electromagnetic interference. Another phenomenon is that when we listen to the radio, watch TV, or use a computer during a thunderstorm, there will be "squeaky" noises on the radio, and image jitters on the TV and computer, etc. These are all caused by the interference generated by lightning. electromagnetic interference.
