Description
Technical field
The present invention relates to a kind of communications optical cable, especially a kind of resistant to bending self-supporting optical cable.
Background technology
The laying of optical cable often has overhead route segment.The aerial optical cable of non-self-supporting needs that steel strand wires are arranged in laying
It is hung with hook, this not only results in construction cost raising, and construction speed declines, and there is the hidden danger destroyed by thunder and lightning.It removes
Construction equipment generally carries metal material in conventional cable, and being introduced when thunder and lightning damages the event of communication equipment also by optical cable has
Occur.Further, since dead weight is larger, draw again than low, cable laying operation relative difficulty.Therefore, existing optical cable exists to rely on and assist
Bearing equipment and inconvenience is laid, is easy to lead thunder and leads to the problem of security risk.
Invention content
The object of the present invention is to provide a kind of resistant to bending self-supporting optical cables.The present invention, which has, to assist load-bearing to set
It is standby and be easy to lay, and the feature that lightning protection properties are preferable.
Technical scheme of the present invention：A kind of resistant to bending self-supporting optical cable, including non-metal reinforcement member disposed in parallel and light
Fibre, outer fiber are equipped with loose sheath, and loose sheath external spiral is arranged with water blocking yarn, glass fiber tape is arranged with outside water blocking yarn；
Further include coat glass fiber tape and non-metal reinforcement member oversheath, two oversheaths be included in glass fiber tape and
Suspender belt between non-metal reinforcement member；The cushion hole vertical with non-metal reinforcement member axis is equipped at intervals on the suspender belt.
In a kind of resistant to bending self-supporting optical cable above-mentioned, the oversheath of the non-metal reinforcement member is equipped with gap, and
Gap is located at backwards to the side of optical fiber.
In a kind of resistant to bending self-supporting optical cable above-mentioned, the non-metal reinforcement member is fibre reinforced composites line.
Compared with prior art, the present invention has reinforcer self-supporting construction, and steel strand wires need not be preset in aerial laying
And hook, it is effectively improved construction efficiency.Meanwhile the structure of all dielectric of the present invention, it is not easy to lead thunder, when construction can exempt to be grounded
Processing.In addition, all-medium structure lighter weight, draws again than opposite raising, and either reinforcer or communication line and outer shield
The differences in expansion of set is smaller, is not likely to produce gap.
Moreover, present invention overcomes curvature differences existing for two-wire one.Due to dead weight etc., optical cable is always
Sag bent, and the curvature difference of upper and lower two lines may result in and be the largest stress raiser at suspender belt.Suspender belt of the present invention
On pore structure on the one hand for the deformation of suspender belt provide cushion space, prevent from squeezing rupture；On the other hand due to aging etc.
After suspender belt cracking, pore structure can terminate crack, prevent from further spreading.Simultaneously as the line where reinforcer is upper,
Therefore its radius of curvature smaller when optical cable naturally droops squeezes internal stress bigger.Thus, gap structure of the invention, which is similarly, to be added
The sheath of strong part provides deformation space, reduces internal stress, prevents from cracking.
To sum up, the present invention has and need not assist bearing equipment and be easy to lay, and the feature that lightning protection properties are preferable.
Meanwhile the present invention also have the characteristics that it is with long service life.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Reference numeral：10- non-metal reinforcement members, 11- oversheaths, 12- gap, 20- optical fiber, 21- pine sheaths, 22- block water
Yarn, 23- glass fiber tapes, 30- suspender belts, 31- cushion holes.
Specific implementation mode
With reference to embodiment, the invention will be further described, but is not intended as the foundation limited the present invention.
Embodiment：A kind of resistant to bending self-supporting optical cable, including non-metal reinforcement member disposed in parallel 10 and optical fiber 20, optical fiber
20 outsides are equipped with loose sheath 21, and 21 external spiral of loose sheath is arranged with water blocking yarn 22, glass fiber tape 23 is arranged with outside water blocking yarn 22；
Further include the oversheath 11 for coating glass fiber tape 23 and non-metal reinforcement member 10, two oversheaths 11 are included in glass
Suspender belt 30 between fiber band 23 and non-metal reinforcement member 10；It is equipped at intervals on the suspender belt 30 and 10 axis of non-metal reinforcement member
The vertical cushion hole 31 of line.Cushion hole 31 is that extrusion molding is realized by thimble, since plastic extruding direction and the thimble direction of motion hang down
Directly, in addition extending and retracting for thimble needs certain time, therefore cushion hole 31 is usually formed waist-shaped hole, as long as ensureing waist-shaped hole
Length it is reasonable, do not interfere with the intensity of suspender belt.
The oversheath 11 of the non-metal reinforcement member 10 is equipped with gap 12, and gap 12 is located at one backwards to optical fiber 20
Side.
The non-metal reinforcement member 10 is fibre reinforced composites line.The loose sheath 21 is PBT plastic layer.Two
The oversheath 11 and suspender belt 30 of line are integrated, preferably polythene materials.
Operation principle：
The structure of all dielectric of the present invention, it is not easy to lead thunder, when construction can exempt from grounding.Due to reinforcer self-supporting knot
Structure, the present invention need not preset steel strand wires and hook when making somebody a mere figurehead laying, be effectively improved construction efficiency.In addition, the present invention is complete
Dielectric structure lighter weight is drawn again than opposite raising, and the differential expansion of either reinforcer or communication line and oversheath 11
It is different smaller, it is not likely to produce gap.
Moreover, present invention overcomes curvature differences existing for two-wire one.Due to dead weight etc., optical cable is always
Sag bent, and the curvature difference of upper and lower two lines may result in and be the largest stress raiser at suspender belt 30.The present invention is hung
Cushion space on the one hand is provided for the deformation of suspender belt 30 with the pore structure on 30, prevents from squeezing rupture；On the other hand due to aging
Etc. reasons suspender belt 30 crack after, pore structure can terminate crack, prevent from further spreading.Simultaneously as the line where reinforcer
It is therefore its radius of curvature smaller when optical cable naturally droops upper, squeezes internal stress bigger.Thus, gap 12 of the invention
The sheath that structure is similarly reinforcer provides deformation space, reduces internal stress, prevents from cracking.
