Description
Technical field
The present invention relates to a kind of waveguides, and in particular to a kind of anechoic chamber, multi-channel optical fibre waveguide belongs to electromagnetic shielding
Technical field.
Background technique
Shield machine foundations present principles are designed from faraday cup.In the case where not shielding, our electronic equipment
The influence that will receive the strong electromagnetic interference sources such as direct lightning strike or indirect stroke causes equipment that can not work or work exception, most serious occur
When damage, this is that relatively common electromagnetic interference shows, another phenomenon is exactly that we listen radio reception when thundering
Machine sees TV, and using computer, radio will appear noise " creakily ", television set, and computer will appear flating etc., this
It is all electromagnetic interference caused by the interference that thunder and lightning generates a bit.Specific measure: using shielding product, and reliable ground, will be external
Electromagnetic interference barrier outside, including the electromagnetic wave barrier that internal equipment is generated, one equipotential body of composition in this way can
Effectively shielding electromagnetic interference, optical fiber waveguides in conjunction are to cross wall purposes for shielding non-metallic material cable in computer room or shielding cabinet,
The access for not influencing shielding properties is provided for equipment such as optical fiber, RF transmitters, but existing waveguide is all hollow
Structure, can leave very big gap after the lines such as optical fiber pass through, poor sealing effect and shield effectiveness is also bad, but existing technology
It is difficult to overcome the above problem.
Summary of the invention
It is all hollow structure the technical problem to be solved by the present invention is to overcome existing waveguide, after the lines such as optical fiber pass through
Very big gap can be left, poor sealing effect and shield effectiveness also bad problem provide a kind of anechoic chamber, multi-channel optical fibre wave
Conduit.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
The present invention provides a kind of anechoic chamber, multi-channel optical fibre waveguides, including waveguide outer ring, waveguide fixed body, wave
Conduit connecting screw, optical fiber perforation, bolt, nut, foundation and block body, the inside of the waveguide outer ring are interspersed with the waveguide
Pipe fixed body, the inside of the waveguide fixed body are interspersed with the waveguide connecting screw, on the waveguide connecting screw
The optical fiber is perforated there are six being uniformly arranged, and is provided with the block body at the center of the bolt, is set at the top of the block body
It is equipped with the bolt, the top of the bolt is provided with the nut, is additionally provided with foundation in the bottom end of the block body.
As a preferred technical solution of the present invention, the radius of the optical fiber perforation is 2.5mm.
As a preferred technical solution of the present invention, the optical fiber perforation is in rounded shape to be enclosed in the conduit connection spiral shell
Around the center of circle of bar.
The beneficial effects obtained by the present invention are as follows being: the device is a kind of anechoic chamber, multi-channel optical fibre waveguide, the device light
Just, sealing effect is good, does not influence shielding properties for fine line size and the size in hole；A piece optical fiber cable is divided into six roots of sensation optical fiber
The gap that line, every optical fiber cable and hole generate is with regard to very little, to improve shield effectiveness, whole device design is rationally, easy to use,
Solving existing waveguide is all hollow structure, can leave very big gap after the lines such as optical fiber pass through, poor sealing effect and
Shield effectiveness also bad problem.
