Embodiment
As shown in Figure 1, a kind of multi-functional composite cable comprises three parts, local area network signal hop 1, enhancement signal transmission part 7 and TV signal hop 9.
Local area network signal hop 1 is followed successively by twisted wire group, inner restrictive coating 2 and external sheath layer 3 from inside to outside; The twisted wire group comprises some groups of twisted pair wires 4; Every group of twisted pair wire coats conductor 6 stranded formation of a layer insulating 5, the said twisted wire group of the common again stranded formation of these some groups of twisted pair wires respectively by two skins.Wherein provided the twisted wire group of being made up of four groups of twisted pair wires among Fig. 1, these four groups of twisted pair wires carry out stranded through same pitch.Wherein, Conductor 6 is that hypoxemia or the oxygen-free copper bar of 2.6mm processed through wire drawing, annealing by diameter; The wire gauge of conductor 6 is (23-24) AWG; Heart yearn is that the insulating barrier of conductor 6 is moulded fat (FEP) material by high density polyethylene (HDPE) (HDPE) or fluorine and processed, according to the difference of transmission performance, thickness of insulating layer be 0.190+/-0.02mm or 0.27+/-0.02mm; Two heart yearns of twisted pair wire are the twisting shape, and four pairs of lines all adopt the back twist of (30～60) % technological; Can select whether to add cross between four pairs of twisted pair wires and fill, the width that cross is filled be 5.0+/-0.1mm, thickness be 0.50+/-0.1mm, interior thickness be 0.50+/-the cross shim of 0.1mm; Inner restrictive coating is moulded fat (FEP) material by polyvinyl chloride (PVC), polyethylene (PE), low smoke and zero halogen (LSZH) or fluorine and is processed, thickness be 0.50+/-0.05mm.The thickness of oversheath be 0.50+/-0.05mm, external diameter be 6.2+/-0.5mm., external sheath layer is moulded fat (FEP) material by polyvinyl chloride (PVC), polyethylene (PE), low smoke and zero halogen (LSZH) or fluorine and is processed.
Enhancement signal transmission part 7 is followed successively by PU hollow pipe 8 and external sheath layer 3 from inside to outside, and the PU hollow pipe is a screw-like PU (polyurethane) blank pipe, and it is peripheral that external sheath layer 3 is coated on this PU hollow pipe.Luo line blank pipe external diameter be 15.0+/-5.0mm; Thickness 0.4+/-0.05mm; The outer protective sleeve layer thickness be 0.5+/-0.05mm, external diameter be 16.0+/-5.0mm, external sheath layer is moulded fat (FEP) material by polyvinyl chloride (PVC), polyethylene (PE), low smoke and zero halogen (LSZH) or fluorine and is processed.
The multi-functional composite cable of the utility model has four important unit for electrical property parameters: impedance, decay, electromagnetic interference, return loss the time have taken into full account this balanced relation in design.
Impedance is a parameter the most basic in the electric property, and it is by conductor lines footpath, two conductor centre-to-centre spacing, these three parameter determining of insulative dielectric constant, and not matching of any impedance all can cause the error of final acknowledge(ment) signal.Therefore when design, taken into full account the influence of these three factors, the conductor lines footpath is big, and low cut can be got well, but cost raises, and finish line footpath is bigger than normal; The conductor lines footpath is little, and decay can be influenced.Consider also simultaneously when producing that pitch is different and tension force is inconsistent; Can produce each line two conductor centre-to-centre spacing difference is influenced impedance; Go out different insulated wire footpath according to different multiple twin pitch design, guarantee behind the finished product that the right resistance value of every line is controlled at about 100+/-15 ohm.
Decay is divided into conductor decay and diectric attenuation two parts, and the conductor decay is relevant with resistance, therefore adopts oxygen-free copper or hypoxemia copper product, makes resistance reach minimum; Diectric attenuation is relevant with material, and insulating material selects for use high density polyethylene (HDPE) (HDPE) or fluorine to mould fat (FEP) material, all is the smaller material of dielectric constant and dielectric loss angle.
Aspects such as it is directly little with line that the superior performance of this wire rod is embodied in anti-electromagnetic interference, and cost is low.When the design of this novel sheath obtains a circular section, make many cables independently separately, stability of structure is good; It is strong that anti-electromagnetism is done the sorrow ability; This 8 word sheaths effectively keep every pair of line to separate in cavity, and the position interfixes each other, and this in addition 8 word sheaths have reduced the line footpath of whole cable substantially; Effectively improve wiring space; Owing to be independently between this design cable, improved the field decay farthest between each twisted pair wire and another twisted pair wire, thereby improved electromagnetic interference and fade performance simultaneously.Another characteristics; Since in each independent cable respectively in the oversheath protection, and ingenious design that can 8 word oversheaths can not only solve lead mutually outer lines in the cable between group between electromagnetism do sorrow, thereby thereby effectively going here and there the sorrow problem this dual effect under between the improvement group; It is little not only to have the line footpath; The more and more littler characteristics of particularly crosstalking between increase group with frequency. and handling ease, save material, be a getting twice the result with half the effort. Eco-power new product.
Return loss receives the influence of input impedance; Since with load impedance do not match or make in the inhomogeneous point in cycle; Thereby the reflection that produces signal; Input impedance is fluctuateed up and down at characteristic impedance value, and the energy of reflection aggravates along with the increase of frequency, even can produce the sudden change significantly of return loss.The utility model adopts the preparatory back twist technology of pair twist, eliminates the influence of periodic inconsistent generation to input impedance, improves the stability of input impedance, thereby optimizes return loss.
