Abstract
The utility model relates to a duct fiber cable, including the sheath, set up the enhancement core that the inside central point of sheath put, the sheath with strengthen being provided with fibre -optic catheter and filler rod between the core, the fibre -optic catheter with the quantity sum of filler rod is five. The utility model discloses it can fill up the inside space of sheath to be provided with the filler rod inside the sheath, has strengthened the structural strength of optical cable.
Description
Technical field
This utility model is related to a kind of optical cable and in particular to a kind of duct optical cable.
Background technology
Optical cable is mainly made up of optical fiberss (the thin glass fiber as hair) and plastic protective sleeve pipe and plastic peel.Light
Cable is the prevailing transmission instrument of the various Information Network of current information-intensive society.
The stiffener of existing duct optical cable, its tensile force is poor, and bending property is poor, and flexibility is not it is difficult to solve anti-
Torsion problem, stripping bothers.And because cable interior number of fibers is not necessarily filled completely, have shadow for duct optical cable structural strength
Ring.
In view of above-mentioned defect, the design people, actively research and innovation in addition, to founding a kind of pipeline of new structure
Optical cable is so as to more the value in industry.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of duct optical cable.
The technical solution of the utility model is as follows:
A kind of duct optical cable, including sheath, be arranged on the strengthening core of described sheath inner hub location it is characterised in that:
It is provided with fibre-optic catheter and filler rod, the quantity of described fibre-optic catheter and described filler rod between described sheath and described strengthening core
Sum is five；Described sheath internal layer is additionally provided with one layer of enhancement layer being close to described sheath.
Further, described enhancement layer material is metal, and described enhancement layer thickness is 1mm.
Further, described fibre-optic catheter includes the Loose tube of outer layer, be arranged on optical fiber within described Loose tube and
Filling glue between described Loose tube and described optical fiber.
Further, described sheath material is polypropylene.
Further, described strengthening core is steel wire.
By such scheme, this utility model at least has the advantage that
This utility model duct optical cable, can meet the demand of indoor and outdoor introducing type occasion under thunderbolt or forceful electric power occasion, due to
Cable configuration optimization so that the structure of this optical cable optimizes significantly, light weight, be easily installed charity, and have good cost,
The advantages of continue convenient, pollution-free, can use indoors.
This utility model is internally provided with filler rod in sheath and can fill up the space within sheath, strengthens optical cable
Structural strength.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing detailed
Describe in detail bright as after.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used for this utility model is described, but is not limited to scope of the present utility model.
Referring to Fig. 1, a kind of duct optical cable described in this utility model one preferred embodiment, including outermost sheath 1, protect
Cover 1 internal layer and be provided with one layer of enhancement layer 2, enhancement layer 2 is close to inside sheath 1, enhancement layer 2 is generally metal material, enhancement layer 2
Thickness is 1mm, and sheath 1 inner hub location is provided with strengthening core 5, and strengthening core 5 is steel wire, sets between strengthening core 5 and enhancement layer 2
It is equipped with fibre-optic catheter and filler rod 4, the quantity sum of fibre-optic catheter and filler rod 4 is five, and the inner space of enhancement layer 2 is also filled out
Fill thing 3, fibre-optic catheter includes the Loose tube 6 of outer layer, be arranged on optical fiber 7 within Loose tube 6 and Loose tube 6 and optical fiber 7 it
Between filling glue 8.In this utility model, sheath 1 material is polypropylene.
This utility model duct optical cable, can meet the demand of indoor and outdoor introducing type occasion under thunderbolt or forceful electric power occasion, due to
Cable configuration optimization so that the structure of this optical cable optimizes significantly, light weight, be easily installed charity, and have good cost,
The advantages of continue convenient, pollution-free, can use indoors.
This utility model is internally provided with filler rod in sheath and can fill up the space within sheath, strengthens optical cable
Structural strength.
The above is only preferred implementation of the present utility model, be not limited to this utility model it is noted that
For those skilled in the art, on the premise of without departing from this utility model know-why, can also do
Go out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
