Description

Communication data composite rope
Technical field
The present invention relates to a kind of communication cable, more particularly to a kind of communication data composite rope.
Background technology
The structure of common single type communication cable：Its primary structure of the cable of pair twist structure is to extrude one layer outside copper conductor Insulate, stranding after single line pair twist, outside uses the structure of polyolefin oversheath, and coaxial cable primary structure is to be extruded outside inner wire Or wrapped one layer of insulation, then using aluminium foil or braiding as structure of the polyolefin after outer conductor as oversheath, due to communication The said structure limitation of cable, in exterior finish distributing system, automated detection system, cause to stretch that larger, quality is unstable It is fixed, connect up it is cumbersome, it is unreliable and influence performance.
The content of the invention
The present invention provides a kind of communication data composite rope, and this communication data composite rope improves loss（INSERTION LOSS）1dB surpluses, increase characteristic impedance（IMPEDANCE）1.5% stability, while ensuring the stable transporting of cable While energy, the performance of the transmission electricity of copper cable is added.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of communication data composite rope, including：Steel conductor, Coaxial conductor, eight copper conductors for being coated with polyethylene layer and oversheath body；It is exhausted that the coaxial conductor outer surface is coated with plastics Edge layer, this plastic insulating layer outer surface are coated with the first wire sheathing, and the first inner restrictive coating is coated on first metal and compiled Tissue layer outer surface；
Eight copper conductors are twisted two-by-two forms four pairs of twisted wires pair to be communicated as information, the four twisted pair wires centering the One twisted wire to, the second twisted wire to, the 3rd twisted wire pair and the 4th twisted wire to be arranged in order counterclockwise and it is twisted form conductive cable core, the One twisted wire pair and the 3rd twisted wire pair are with the second twisted wire pair and the 4th twisted wire to spaced, and four twisted pair wire is to respective outer surface Foil shielding layer is coated with, a polyester belt is coated on described around the foil shielding layer outer surface, the second inner restrictive coating is wrapped in Polyester belt outer surface；
The oversheath body includes the first sub- sheath, the second sub- sheath and the 3rd sub- sheath, this first sub- sheath, the second son There is " people " font connecting portion, the first of this " people " font connecting portion connects muscle portion, second at sheath and the 3rd sub- sheath center Even muscle portion and the 3rd company's muscle portion are connected respectively to the described first sub- sheath, the second sub- sheath and the 3rd sub- sheath, the first sub- sheath The steel conductor outside surfaces are coated on, the second sub- sheath is coated on the first inner restrictive coating outer surface, the 3rd sub- sheath cladding In the second inner restrictive coating outer surface；
The steel conductor, the first wire sheathing and proof copper-wire braided screen layer positioned at oversheath body and " people " font by connecting Some spaced plain conductor electrical connections in socket part；
The pitch of first twisted wire pair is 15 ~ 15.5mm, and the pitch of second twisted wire pair is 13.5 ~ 13.9mm, institute The pitch for stating the 3rd twisted wire pair is 14.2 ~ 14.6mm, and the pitch of the 4th twisted wire pair is 12.7 ~ 13.1mm；
