Abstract
The invention provides a signal transmission cable with improved conductor structures, belonging to the technical field of wires and cables. The signal transmission cable comprises one or more wire groups, wherein each wire group comprises a plurality of conductors; and each conductor is covered by an insulating sheath. The signal transmission cable is characterized in that the conductors are formed by stranding a plurality of fine copper wires or a plurality of fine copper-plated aluminium wires. The signal transmission cable has the following advantages: the structures of the conductors in the prior art have been improved to be formed by stranding a plurality of fine copper wires or a plurality of fine copper-plated aluminium wires under the premise of overcoming the prejudice in the prior art, thus not only embodying the flexibility, being convenient to lay and preventing breakage but also enhancing the strength and avoiding tensile failure.
Description
Technical field
The invention belongs to technical field of electric wires and cables, be specifically related to the signal-transmitting cable that a kind of conductor improves structure
Background technology
Signal-transmitting cable is widely used in being not limited to the following railway running number that exemplifies and confirms that the point type reply data transmission of system, track-circuit signalling transmission, ocean navigation transmit with the multifunctional signal of the transmission of signals such as digital measurement and control signal transmission, telephone network and intelligent building wiring, the signal transmission of road monitoring network and radio frequency and high-resolution multimedia interface number (HDMI) communication signal, or the like.
In Chinese patent literature, reach more than over one hundred about the technical information of signal-transmitting cable, slightly with exemplify as CN2726073Y, CN2879360Y, CN2432662Y, CN200983283Y, CN201170976Y and CN201294119Y, or the like.These patent schemes comprise that signal-transmitting cable that the patent scheme that still excludes is related and the signal-transmitting cable that is at present in the military service (use) exist common shortcoming: promptly flexibility is poor, adaptability degree during cable laying operation is low, be prone to the arch that is difficult to eliminate when for example in laid processes, running into the turning round of wide-angle, cause difficulty of construction to increase; It is higher to occur the probability broken in work progress, causes the wasting of resources.
For flexibility and the tensile strength of improving signal-transmitting cable, almost exceptionally mentality of designing is bet the physicochemical characteristics of insulating case, line group sheath and inside and outside sheath material at present not in (paying close attention to) cable core, but, quilt use widely facts have proved and produces little effect, industry continues to explore with keeping unremitting from start to finish for this reason, phase gets and remedies aforesaid shortcoming, but does not see the report that achieving success is arranged up to now.For this reason, the applicant has done positive design, finds a way to resolve the problem, and technical scheme described below produces under this background
Summary of the invention
Task of the present invention is to provide a kind of desirable flexibility is used the conductor improvement structure of conveniently laying and avoiding breaking in laying task with excellent tensile strength signal-transmitting cable that has.
Task of the present invention is finished like this, a kind of conductor improves the signal-transmitting cable of structure, comprise one or more line groups, each line group comprises many conductors, every conductor is coated with insulating sleeve outward, is characterised in that: described conductor is by the complex root thin copper wire or the thin aluminium wire of complex root copper facing is stranded constitutes.
In a specific embodiment of the present invention, described shielding conductor group also comprises first lapping layer, vertical covering and first restrictive coating, first lapping layer is wrapped outside described shielding conductor group, vertical covering is vertical to wrap in outside first lapping layer, first restrictive coating is located at outside the vertical covering, sets gradually water blocking layer, second lapping layer, second restrictive coating, armour and oversheath outside first restrictive coating.
In another specific embodiment of the present invention, be provided with gasket for packing between the spatial domain of described shielding conductor group.
In another specific embodiment of the present invention, described first lapping layer is the polyester twining package tape.
In another specific embodiment of the present invention, described vertical covering is a copper strips.
Also have in the specific embodiment of the present invention, described first restrictive coating is a high density polyethylene (HDPE), and is laid with an earial drainage line in first restrictive coating.
More of the present invention and in specific embodiment, described water blocking layer is the twining package tape that blocks water.
In of the present invention and then specific embodiment, described second lapping layer is the glass fibre twining package tape.
Again more and in specific embodiment, described second restrictive coating is a flame-proof polyvinyl chloride described armour is a steel band of the present invention, and described external sheath layer is a low smoke halogen-free flame-retardant polyolefin.
In again of the present invention and then specific embodiment, described gasket for packing is a polypropylene.
Technical scheme provided by the invention is owing to change into the structure of the conductor in the prior art by the complex root thin copper wire under the prerequisite that has overcome the prejudice in the prior art or the thin aluminium wire of complex root copper facing is stranded constitutes, lose thereby can embody flexibility and be convenient to lay and prevent, can gain in strength again and avoid breaking.
Description of drawings
Fig. 1 is the embodiments of the invention schematic diagram.
Fig. 2 is the structure chart of the shielding conductor group of structure shown in Figure 1.
Embodiment
Please be referring to Fig. 1 and Fig. 2, three line groups 1 have been provided in the present embodiment, line group 1 can be the twisted pair wire group, it also can be quad, can also be the shielding quad, present embodiment be the shielding quad, and each line group 1 includes four conductors 11, be coated with insulating sleeve 111 outside each conductor 11, the material of insulating sleeve 111 is plastics (PLSCONFMs).Shielding conductor group 1 also comprises first lapping layer 12, vertical covering 13 and first restrictive coating 14, first lapping layer 12 is the polyester twining package tape, wrapped outside four shielding conductor groups 1, lapping layer 13 is a copper strips, vertical wrapping in outside first lapping layer 12, and first restrictive coating 14 is high density polyethylene (HDPE) (HDPE), squeezes to overlay on outside the vertical covering 13.In first restrictive coating 14, also be laid with an earial drainage line 141, and to be provided with material in the spatial domain between aforesaid three shielding conductor groups 1 be polyacrylic gasket for packing 7, ensure the roundness of cables 2 behind stranding by gasket for packing 7.Aforesaid pair twist group is that two eradication edge cores twist together by certain pitch; And aforesaid quad is four to thoroughly do away with the edge cores and twist together by certain pitch; Aforesaid shielding quad is that four eradication edge cores twist together by certain pitch.
As technical essential of the present invention, aforesaid conductor 11 is adopted the stranded formation of some thin copper wires (also can claim some fine copper wires), and before the present invention proposes, all signal-transmitting cable 2 is owing to fettered by traditional design concept and use some leads usually, thereby makes the pliability of cable and tensile strength be difficult to assurance.By the stranded conductor 11 of filling the post of of single thin copper wire, the result has obtained beyond thought technique effect yet the present invention program is owing to overcome technology prejudice, makes the ultimate attainment lifting of flexibility and tensile strength.
