Description
Technical field
The invention belongs to multifiber cable and shielded wall field, particularly relate to a kind of waveguide and multifiber cable
Shielding through wall device.
Background technology
It is through waveguide that general optical cable shielded the common method of wall, utilizes the cut-off waveguide of waveguide to make
With reaching to shield the purpose of electromagnetic wave, it is desirable to the diameter of optical cable is less than the caliber of waveguide.Cutting of waveguide
Only frequency is corresponding with its caliber, and caliber is the least, and its cut-off frequency is the highest, when high-grade shielding construction
When the cut-off frequency upper limit is higher, corresponding waveguide caliber than multifiber cable thin a lot, it is impossible to by commonly
Waveguide realize shielded wall.
Summary of the invention
It is an object of the invention to provide a kind of waveguide and multifiber cable shielding through wall device, to solve
The shielding of above-mentioned multifiber cable wall problem.
Technical scheme is as follows:
A kind of waveguide, axial along pipeline, the tube wall of interior conduit is formed the circle of multiple outwardly convex
The pipeline of cylindricality, the pipeline of described cylinder offers opening.
Further: the interior conduit of described waveguide is cone, cylindrical or corrugated tubing.
The invention still further relates to a kind of multifiber cable shielding through wall device, including: constituted many by organizing optical fiber more
Core optical cable；Waveguide, axial along pipeline, the tube wall of interior conduit is formed the circle of multiple outwardly convex
The pipeline of cylindricality, the pipeline of described cylinder offers opening；Described optical fiber one_to_one corresponding passes axially through
The pipeline of described cylinder；Filled core, is used for clogging described waveguide, its outer surface and described waveguide
Inner surface fit, make the pipeline of each described cylinder form independent waveguide-tube.
Further: described filled core is more than or equal to 90% with the contact area of described waveguide.
Further: described filled core is cone, and the inner surface of described waveguide is and described filled core phase
The internal conical surface of socket.
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 being crossed wall punishment
Becoming the optical fiber of multiple minor diameter, it is achieved shielded wall, its structure and technique are simple, each waveguiding structure
Cut-off frequency all can meet the requirement of shielding construction.

Detailed description of the invention
The present invention is described in detail below in conjunction with the accompanying drawings.
As shown in Fig. 1～2, a kind of waveguide 1 in illustrative embodiment, it is shaped as, along pipeline
Axially, the tube wall of interior conduit forms the cylindrical pipeline 2 of multiple outwardly convex, cylindrical pipe
Road 2 offers opening.The interior conduit of waveguide 1 is cylindrical, cone or corrugated tubing.
The invention still further relates to a kind of multifiber cable shielding through wall device, as shown in Figures 1 to 3, including: by many
The multifiber cable that group optical fiber is constituted；Waveguide 1, axial along pipeline, the tube wall of interior conduit is formed
The cylindrical pipeline 2 of multiple outwardly convexs, cylindrical pipeline 2 offers opening, cylindrical pipe
The diameter in road 2 depends on required cut-off frequency；Often group optical fiber correspondence is through a cylindrical pipeline 2；
Filled core 3, is used for clogging waveguide 1, makes the pipeline 2 of each cylinder form independent waveguide-tube.
The inner surface of waveguide 1 fits tightly with the outer surface of filled core 3, and contact area is more than or equal to 90%,
When contact area is less than this value, shield effectiveness is poor.
Preferably, as shown in Figures 4 and 5, filled core 3 be cone, the inner surface of waveguide 1 be with
The internal conical surface that filled core 3 socket-connects, preferably 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 the pipeline of each cylinder
2 with filled core 3 formed pipeline become waveguiding structure, the cut-off frequency of each waveguiding structure be satisfied by screen
The requirement of shield structure.
During use, peel off insulation sheath, be divided into many for one section that the multifiber cable being relatively large in diameter was used for wall
Group small diameter fiber, often group optical fiber is through a cylindrical pipeline 2, finally with filled core 3 by waveguide
Pipe 1 clogs.
