Abstract
The utility model discloses a thin-wall data transmission cable with twisted wire cores. The data transmission cable comprises a plurality of conductor groups and insulating layers, wherein each conductor group is composed of two conductors; insulating layers are wrapped at the outer side of the conductors; branched shielding layers and an inner protecting sleeve layer are sequentially wrapped at the outer side of the plurality of conductors; a main shielding layer and an outer protecting sleeve layer are sequentially wrapped at the outer side of the inner protecting sleeve layer of the plurality of conductors; the insulating layers, the inner and the outer protecting sleeve layers are made from high-polymer low-smoke zero-halogen materials; the conductors are made from tinned copper wires; the branched shielding layers are formed by weaving the tinned copper wires; and the main shielding layer is formed by weaving copper wires or winding copper strips. The data transmission cable has a simple structure; the insulating layers, the inner and the outer protecting sleeve layers are made from the high-polymer low-smoke zero-halogen materials, thereby being not easy to combust; the conductors are divided into a plurality of conductor groups so as to avoid mutual interference of different lines; and one single tinned branched shielding layer is arranged between every two conductor groups, and the main shielding layers are arranged outside the conductor groups so as to defend the external electromagnetic interference of adjacent cables.
Description
Technical field:
The utility model relates to field of cables, relates in particular to a kind of thin-walled core strand to data cable.
Background technology:
Cable is in order to transmit electricity (magnetic) energy, the wire product of information and the conversion of realization electromagnetic energy.Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Electric wire mainly comprises bare wire, electromagnetic wire and electrical equipment and electrical insulated electric conductor, power cable, telecommunication cable and optical cable.
The utility model insulating barrier and interior external sheath layer all adopt macromolecule low smoke and zero halogen material, break traditional mode transmission cable and all adopted polythene material, because polyethylene is not suitable for using on rolling stock, the polyethylene easy firing, and also the generation grease easily causes second-time burning when burning.For fear of the phase mutual interference between the different circuits, all adopt separately zinc-plated screen between each conductor group after, add up screen outward, to resist the electromagnetic interference of extraneous adjacent cable.
The utility model content:
The purpose of this utility model provides a kind of thin-walled core strand to data cable, be applicable to near-end crosstalk attenuation is required the higher sensitive signal and the transmission of two-forty model, and be subjected to signal control device under the serious electromagnetic interference condition at circuit, be more suitable for the wiring of data computer system in the automation equipment of large sized complete sets of equipment.
The technical solution of the utility model is as follows:
A kind of thin-walled core strand is to data cable, comprise several conductor groups, insulating barrier, it is characterized in that: the stranded formation of conductor that described several conductor groups have two outsides to be enclosed with insulating barrier, the outside of described several conductor groups is enclosed with sub-shield, inner restrictive coating successively, and the outside of the inner restrictive coating of described several conductor groups is enclosed with total screen, external sheath layer successively.
Described thin-walled core strand is characterized in that data cable: described insulating barrier, inside and outside restrictive coating adopt macromolecule low smoke and zero halogen material.
Described thin-walled core strand is to data cable, and it is characterized in that: described conductor adopts tinned copper wire, and described sub-shield adopts the tinned copper wire braiding to constitute, and described total screen adopts copper wire braiding or the wrapped formation of copper strips.
The utility model has the advantages that:
Of the present utility model simple in structure, insulating barrier and interior external sheath layer all adopt macromolecule low smoke and zero halogen material, nonflammable, conductor is divided into several conductor groups, for fear of the phase mutual interference between the different circuits, after all adopting zinc-plated separately sub-shield between each conductor group, add up screen outward, to resist the electromagnetic interference of extraneous adjacent cable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
A kind of thin-walled core strand is to data cable, comprise several conductor groups, insulating barrier 1, several conductor groups have two outsides to be enclosed with the conductor 2 stranded formations of insulating barrier 1, the outside of several conductor groups is enclosed with sub-shield 3, inner restrictive coating 4 successively, the outside of the inner restrictive coating 4 of several conductor groups is enclosed with total screen 5, external sheath layer 6 successively, insulating barrier 1, inner restrictive coating 4, external sheath layer 6 adopt macromolecule low smoke and zero halogen material, conductor 2 adopts tinned copper wire, sub-shield 3 adopts the copper wire braiding to constitute, and total screen 5 adopts copper wire braiding or the wrapped formation of copper strips.
