Due to change of the structure of the waveguide tube, the multi-core optical cable is divided into multiple optical fibers with small diameters, so that shield wall-through can be achieved.
Description
Technical field
The invention belongs to multifiber cable and shielded wall field, relate in particular to a kind of waveguide and multifiber cable shielding through wall device.
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 in the time that 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.
Summary of the invention
The object of the present invention 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 kind of waveguide, along pipeline axially, on the tube wall of interior conduit, form the columniform pipeline of multiple outwardly convexs, described columniform pipeline offers opening.
Further: the interior conduit of described waveguide is conical, cylindrical or threaded line pipe.
The invention still further 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 multiple 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 each described columniform pipeline 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, and 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 invention has the beneficial effects as follows: by changing the structure of waveguide, multifiber cable is punished into the optical fiber of multiple minor diameters at mistake wall, realize and shielded wall, 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 present invention is described in detail.
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 multiple outwardly convexs, columniform pipeline 2 offers opening.The interior conduit of waveguide 1 is cylindrical, taper shape or threaded line pipe.
The invention still further 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 multiple 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 during lower than this value, 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.
When use, multifiber cable larger diameter was used for to a section of wall and peels off insulation sheath, and be divided into many group small diameter fiber, every group of optical fiber, through a columniform pipeline 2, finally clogs waveguide 1 with filled core 3.
