Background technology
The common method that general optical cable shielded wall is through waveguide, utilizes the cut-off waveguide effect of waveguide to reach the electromagnetic object of shielding, requires the diameter of optical cable less than the caliber of waveguide.The cutoff frequency of waveguide is corresponding with its caliber, and caliber is less, and its cutoff frequency is higher, and when the cutoff frequency upper limit of high-grade shielding construction is higher, corresponding waveguide caliber is thin more a lot of than multifiber cable, cannot be realized and be shielded wall by common waveguide.
Utility model content
The purpose of this utility model is to provide a kind of waveguide and multifiber cable shielding through wall device, with solve above-mentioned multifiber cable shielding wall problem.
Technical scheme is as follows:
A waveguide, along pipeline axially, on the tube wall of interior conduit, form the columniform pipeline of a plurality of outwardly convexs, described columniform pipeline offers opening.
Further: the interior conduit of described waveguide is conical, cylindrical or threaded line pipe.
The utility model also relates to a kind of multifiber cable shielding through wall device, comprising: by the multifiber cable of organizing optical fiber more and forming; Waveguide, along pipeline axially, on the tube wall of interior conduit, form the columniform pipeline of a plurality of outwardly convexs, described columniform pipeline offers opening; Described optical fiber one by one correspondence passes described columniform pipeline vertically; Filled core, for clogging described waveguide, the inside surface of its outside surface and described waveguide fits, and makes columniform pipeline described in each form independently waveguide pipeline.
Further: the contact area of described filled core and described waveguide is more than or equal to 90%.
Further: described filled core is conical, the inside surface of described waveguide is the internal conical surface socket-connecting with described filled core.
Further: the material of described filled core is metal, or its outer wall is the coat of metal.
The beneficial effects of the utility model are: by changing the structure of waveguide, multifiber cable is punished into the optical fiber of a plurality of minor diameters at mistake wall, realization shielded wall, and its structure and technique are simple, and the cutoff frequency of each waveguiding structure all can meet the requirement of shielding construction.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Fig. 1～2, a kind of waveguide 1 in illustrative embodiment, it is shaped as, along pipeline axially, on the tube wall of interior conduit, form the columniform pipeline 2 of a plurality of outwardly convexs, columniform pipeline 2 offers opening.The interior conduit of waveguide 1 is cylindrical, taper shape or threaded line pipe.
The utility model also relates to a kind of multifiber cable shielding through wall device, as shown in Figures 1 to 3, comprising: by the multifiber cable of organizing optical fiber more and forming; Waveguide 1, along pipeline axially, on the tube wall of interior conduit, form the columniform pipeline 2 of a plurality of outwardly convexs, columniform pipeline 2 offers opening, the diameter of columniform pipeline 2 depends on required cutoff frequency; Every group of optical fiber is corresponding to a columniform pipeline 2; Filled core 3, for clogging waveguide 1, makes each columniform pipeline 2 form independently waveguide pipeline.The intimate laminating of the inside surface of waveguide 1 and filled core 3, contact area is more than or equal to 90%, and when contact area is worth lower than this, shield effectiveness is poor.
Preferably, as shown in Figures 4 and 5, filled core 3 is conical, and the inside surface of waveguide 1 is the internal conical surface socket-connecting with filled core 3, better to realize the quality of fit of waveguide 1 and filled core 3.
The material of filled core 3 is metal, or its outer wall is the coat of metal, makes each columniform pipeline 2 and the pipeline that filled core 3 forms become waveguiding structure, and the cutoff frequency of each waveguiding structure all meets the requirement of shielding construction.
During use, the larger multifiber cable of diameter was used for to a section of wall and peels off insulation sheath, and be divided into many group smaller diameter fiber, every group of optical fiber, through a columniform pipeline 2, finally clogs waveguide 1 with filled core 3.
