Description
Technical field
The present invention relates to a kind of micro- cable of easily difference air-blowing layer-twisted type and its manufacture method.
Background technology
Micro optical cable middle sleeve diameter for air-blown installation is small, and wall thickness is thin, in cabling process usually using prick yarn with
Certain twisting pitch for tightening tension force and fixing cable core, it is usually high polymer material that these, which prick yarn, when by sheath process, shield
The heat of set, which can be delivered to, to be pricked on yarn, and high polymer material meeting heat shrinkable, gently can then be made cable core sleeve stress and be flattened, influence
Sleeve pipe bending property, it is heavy then optic fibre force in cable core sleeve pipe can be made and influence fiber transmission performance.It is to adopt for this common practice
Alleviate above mentioned problem by the use of the aramid fiber material of lower shrinkage as the bundle yarn material of air-blowing micro-cable, but aramid fiber material not only price compared with
Height, and be difficult to cut to remove in work progress, inconvenience is brought to the construction of optical cable difference, particularly new at present construction peace
The requirement of dress method carries out difference to sleeve pipe in connector box and stayed with disk, proposes requirements at the higher level to the bending property of sleeve pipe, does not wish
Sleeve surface is hoped to have any bundle trace, and prior art is difficult to solve the above problems.
The content of the invention
One kind that the technical problems to be solved by the invention are to provide for above-mentioned the shortcomings of the prior art is easily divided
The micro- cable of air-blowing layer-twisted type and its manufacture method of discrimination, the cable configuration is simple, and convenient using difference, manufacturing cost is low, is easy to apply
If installation is stayed with disk.
The present invention is that micro- cable technical scheme is used by solving the above problems：Include layer-twisted type cable core and oversheath,
It is characterized in that described layer-twisted type cable core is twisted by Loose tube around center reinforcemen, protected outside layer-twisted type cable core outer cladding
Set, the fusion of described oversheath inwall or partial fusion have the bundle yarn of cable core skeining bundle letter, described bundle yarn material and oversheath
Material is same or like.
By such scheme, described layer-twisted type cable core is twisted by Loose tube around center reinforcemen into SZ, is twisted
Pitch is 60 ~ 200mm.
By such scheme, optical fiber is set with described Loose tube and fills fine cream, be twisted and block water in described cable core
Yarn.
By such scheme, described oversheath is made up of polythene material, and described bundle yarn is polyethylene fibre yarn.
By such scheme, the fusing point of described bundle yarn material is equal to or less than the fusing point of jacket material.
By such scheme, described center reinforcemen is metalloid core reinforcer.
By such scheme, described oversheath external diameter is 4.0-12.0 mm.
The technical scheme of manufacture method of the present invention is：
Make cable core：The Loose tube for being set with optical fiber is twisted around center reinforcemen, and with material character identical with oversheath
Bundle yarn fix cable core twisting pitch；
Extrude oversheath：Cable core is at the uniform velocity passed through into oversheath mould, oversheath is extruded outside the cable core with extruding machine,
In oversheath extrusion process, oversheath inwall is merged with bundle yarn or partial fusion is integrated.
By such scheme, being twisted in cable core has water blocking yarn, and hawser is placed with out in oversheath.
The beneficial effects of the invention are as follows：1st, it is same or like due to pricking yarn material and jacket material so as to prick yarn and making
Blended during work with oversheath inwall, the Loose tube in cable core is no longer influenced by the influence for pricking yarn, and this not only reduces to pine
Sleeve pipe pricks the influence of trace, improves the bending property of Loose tube, once and cable outer sheath stripping, cable core Loose tube it is naturally scattered
Open, difference is fast and convenient, can save difference and engineering time, be easy to laying installation to be stayed with disk；2nd, the present invention is simple in construction, and fibre holds
Amount is big, and low manufacture cost, optical cable good bending property is in light weight, is easy to air-blown installation.
Brief description of the drawings
Fig. 1 is the radial structure profile of an optical cable embodiment of the invention.
Embodiment
Below in conjunction with drawings and examples, the present invention is described in further detail.
Include layer-twisted type cable core and oversheath 1, described layer-twisted type cable core is twisted by Loose tube 6 around center reinforcemen 3
Conjunction is formed, and optical fiber 4 is set with described Loose tube and fills fine cream 5, and being twisted in described cable core has water blocking yarn 2, layer-twisted type
Cable core is twisted by Loose tube around center reinforcemen into SZ, and twisting pitch is 60 ~ 200mm, and Loose tube wall thickness is
0.15mm or so, described center reinforcemen are metalloid core reinforcer, can be aramid yarn reinforcement.Layer-twisted type cable core outsourcing
Oversheath is covered, the fusion of described oversheath inwall or partial fusion have the bundle yarn of cable core skeining bundle letter, and described oversheath is by gathering
Vinyl material is made, and described bundle yarn is polyethylene fibre yarn, and it is identical with jacket material to prick yarn material.
The production method of optical cable is as follows：Ready-made miniature Loose tube is twisted around metalloid core reinforcer into SZ
It is twisted, and yarn is pricked to fix cable core pitch using with the polyethylene fibre of oversheath same nature, it can be applied on request in cable core
Add water blocking yarn, be fabricated to half dry type air-blowing micro-cable cable core；Cable core is at the uniform velocity passed through into oversheath mould, with extruding machine described
