Summary of the invention
The utility model object is to provide a kind of flexible data cable for Indoor Residential Ecological, this flexible data cable for Indoor Residential Ecological effectively raises the flexibility of outside cable, ensure the strain of cable tensionless winkler foundation, form the overcoat with desirable stretch-proof bending resistance, reduce the external diameter of cable greatly, facilitate laying and the problem of emergency maintenance of cable, improve maintenance efficiency and repair quality.
For achieving the above object, the technical solution adopted in the utility model is: a kind of flexible data cable for Indoor Residential Ecological, comprise: four heart yearns, this heart yearn is made up of the polyethylene strip and stranded 6 copper conductors in polyethylene strip outer surface being positioned at center, one inner insulating layer is coated on described heart yearn outer surface, one polyester belt is wrapped in described four heart yearn outer surfaces, some polyethylene fibres are wrapped forms high-modulus polyethylene fibres layer in polyester belt outer surface, and an oversheath insulating barrier is coated on described high-modulus polyethylene fibres layer outer surface; Four described heart yearns are respectively the first heart yearn, the second heart yearn, the 3rd heart yearn and quad along clockwise direction;
The pitch of described first heart yearn is 15 ~ 15.5mm, and the pitch of described second heart yearn is 13.5 ~ 13.9mm, and the pitch of described 3rd heart yearn is 14.2 ~ 14.6mm, and the pitch of described quad is 12.7 ~ 13.1mm.
In technique scheme, further improvement project is as follows:
1., in such scheme, described copper conductor diameter is 0.15 ~ 0.17 mm.
2., in such scheme, described polyethylene fibre diameter is 0.1 ~ 0.12 mm.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utility model is used for the flexible data cable of Indoor Residential Ecological, its heart yearn is made up of the polyethylene strip and stranded 6 copper conductors in polyethylene strip outer surface being positioned at center, and the pitch of the first heart yearn is 15 ~ 15.5mm, the pitch of described second heart yearn is 13.5 ~ 13.9mm, the pitch of described 3rd heart yearn is 14.2 ~ 14.6mm, the pitch of described quad is 12.7 ~ 13.1mm, reduce transmission of electric signals on its loop, produce electromagnetic induction impact, greatly reduce the cross-talk of the communications cable, reduce mutual capacitively coupled, taken into account other electric parameter simultaneously, it also avoid signal of telecommunication delay inequality to increase, secondly, this heart yearn is made up of the polyethylene strip and stranded 6 copper conductors in polyethylene strip outer surface being positioned at center, some polyethylene fibres are wrapped forms high-modulus polyethylene fibres layer in polyester belt outer surface, effectively raise the flexibility of cable, ensure the strain of cable tensionless winkler foundation, form the overcoat with desirable stretch-proof bending resistance, guarantee that its transmission characteristic is steady in a long-term, there is again the advantages such as lightweight, external diameter is little, pliability good, price is low, there is obvious economic benefit and promotional value.
