It is more rare.But it is emphasized that cable is still indispensable, such as the Modem in family（Or light cat）Connect household radio
Interconnection of the internal ICT facilities such as router, enterprise campus, data center etc., still can't do without the connection of cable, with calculating
The extensive use of machine broadband networks, market needs a kind of large capacity, high-speed, attenuation is small, price is low, the easy cable production of installation
Product, to substitute traditional cable and coaxial cable.It is well known that cable is being used among process, easily generate draw, drag, bending,
And situations such as outer is often exposed to, cable is caused to exist using hidden danger, reduces transmission attenuation.
The content of the invention
For defect in the prior art, the utility model proposes a kind of high soft type termite-resistant rodent-resistant wear-resistant tensile nets
Line；These drawbacks existing for solving traditional cable, improve its electric conductivity, flexibility and extensibility, termite-resistant rodent-resistant, it is wear-resisting, into
This low, transmission performance.
To achieve the above object, the utility model proposes a kind of high soft type termite-resistant rodent-resistant wear-resistant tensile cables；From inside to outside
Include successively：Conductor and insulating layer；The conductor and insulating layer composition insulated wire cores；The insulated wire cores two form one to pair twist
A sub- cable core；Filled layer is set between the sub- cable core, filled layer outwards set gradually polyester film, shielded layer one, shielded layer two,
Inner sheath and outer jacket.
Polyether-polyurethane mixture is extruded outside the external conductor of the insulating layer and forms insulated wire cores.
Including four groups of sub- cable cores, in four groups of sub- cable core twisted synthesizing cables, stranding gap is using miniature filling cotton as filled layer.
One polyester film layer of longitudinal wrap outside the stranding；Wrapped aluminum-plastic composite membrane is shielded layer one outside polyester film；Described
The copper free wire that the outer count of aluminum-plastic composite membrane is 40% forms shielded layer two.
Extrude thin environment protection, rat ant proof inner sheath again outside the shielded layer two, extruding butyronitrile material outside inner sheath forms
Outer jacket.
Advantageous effect：
Compared with the prior art, the beneficial effects of the utility model are embodied in：
1st, conductor uses the tin plating annealed copper silk of six classes, and material is softer, and electric conductivity is good, corrosion resistance, anti-oxidant
Performance is stronger, can greatly prolong the service life of light current cable.
2nd, insulation is using polyether-polyurethane mixture, has light-weight, and wearability is good, good insulating, and pliability is preferable.
3rd, shielded layer uses aluminium-plastic tape and count to form dual shield for 40% proof copper-wire braided, and traditional
80% count is compared, and the infrastructure cost is low, and shielding rejection coefficient is excellent, and anti-external world's effect is good, and distorted signals is small, ensures letter
Number transmission quality.
4th, oversheath is formed using inner sheath and outer jacket, and sheath is thin, light-weight, using being protected in environment protection, rat ant proof
Set prevents the injury of termite, home mouse or other food erosion biologies, ensures the normal operation of communication.Nylon sheath wire is protected as outermost layer
Layer has higher mechanical strength and elongation at break, and wearability is good, can improve the service life of cable.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The utility model proposes a kind of high soft type termite-resistant rodent-resistant wear-resistant tensile cables；Include successively from inside to outside：1 He of conductor
Insulating layer 2；The conductor 1 and insulating layer 2 form insulated wire cores；The insulated wire cores two form a sub- cable core 3 to pair twist；Institute
It states and filled layer 4 is set between sub- cable core 3, filled layer 4 outwards sets gradually polyester film 5, shielded layer 1, shielded layer 27, interior shield
Set 8 and outer jacket 9.
Polyether-polyurethane mixture is extruded outside the 2 external conductor of insulating layer and forms insulated wire cores.
Including four groups of sub- cable cores 3, four groups of sub- cable core twisted synthesizing cables, stranding gap is using miniature filling cotton as filled layer 4.
One polyester film layer 5 of longitudinal wrap outside the stranding；Wrapped aluminum-plastic composite membrane is shielded layer 1 outside polyester film 5；Institute
It states the copper free wire that the outer count of aluminum-plastic composite membrane is 40% and forms shielded layer 27.
It extrudes thin environment protection, rat ant proof inner sheath 8 again outside the shielded layer 27, butyronitrile material is extruded outside inner sheath 8
