Description

A kind of CAT6A class netting twines of low smoke and zero halogen

【Technical field】

The utility model is related to the technical field of netting twine, the technology neck of the CAT6A class netting twines of particularly a kind of low smoke and zero halogen Domain.

【Background technology】

Connect LAN, netting twine is requisite.In a local network common netting twine mainly has twisted-pair feeder, Coaxial Network Three kinds of line, optical cable.Twisted-pair feeder, by many data lines constituted to line.Its feature is exactly low price, so wide General application, the insulating barrier of existing netting twine is usually a large amount of using made by polyvinyl chloride, not only producing when netting twine burns Black smoke, can also produce harmful toxic gas, therefore be unfavorable for fire disaster escaping and rescue, existing netting twine is single to lead The insulating barrier of line is typically not provided with easy-peel helicla flute and annulus finishing, due to the solid conductor of netting twine it is general all thinner, because This is easy to the deformation of wire folder or pinch off when wire stripping is carried out.

【The content of the invention】

The purpose of this utility model is exactly, in order to solve the problems of the prior art, to propose a kind of CAT6A of low smoke and zero halogen Class netting twine, not only signal transmission performance is good for the utility model, easy wire stripping, and insulating barrier of the present utility model will not in burning Produce substantial amounts of black smoke and toxic gas.

For achieving the above object, the utility model proposes a kind of CAT6A class netting twines of low smoke and zero halogen, including polyolefin is exhausted Edge protective layer, tension braiding layer, aluminium foil and wire, the outer surface of the tension braiding layer is coated with polyolefin insulation protective layer, The wire is divided into the wire group per two for a group by aluminium foil cladding, and the tension braiding layer is directly sleeved in wire group, The wire includes polyolefin insulation layer and conductive metal core, is coated in the polyolefin insulation layer in conductive metal core, institute State and be also provided with polyolefin insulation layer helicla flute and annulus finishing, between the polyolefin insulation protective layer and tension braiding layer There is the depth in gap, the helicla flute and annulus finishing, accounts for the 3/5 of polyolefin insulation layer thickness, the helicla flute and circle Ring finishing is arranged on the outer surface of polyolefin insulation layer, and the polyolefin insulation layer is provided with one per the length of 5m m-8m m Annulus finishing.

The beneficial effects of the utility model：The utility model replaces traditional polychlorostyrene second by adopting polyolefin insulation layer Alkene insulating barrier, so that netting twine is during burning, will not also produce substantial amounts of black smoke and toxic gas；The utility model is also By in the polyolefin insulation layer of single netting twine, having opened up easy-peel helicla flute and annulus finishing, so that the wiring of netting twine Work is convenient.

Feature of the present utility model and advantage will combine accompanying drawing and be described in detail by embodiment.

【Description of the drawings】

Fig. 1 is a kind of sectional view of the CAT6A class netting twines of low smoke and zero halogen of the utility model；

Fig. 2 is the structural representation of wire of the present utility model；

In figure：1- polyolefin insulation protective layers, 2- tension braiding layers, 3- aluminium foils, 4- wires, 41- polyolefin insulation layers, 42- conductive metal cores, 411- helicla flutes, 412- annulus finishings.

【Specific embodiment】

Refering to Fig. 1 and Fig. 2, the utility model is a kind of CAT6A class netting twines of low smoke and zero halogen, including polyolefin insulation protection Layer 1, tension braiding layer 2, aluminium foil 3 and wire 4, the outer surface of the tension braiding layer 2 is coated with polyolefin insulation protective layer 1, The wire 4 is divided into the wire group per two for a group by the cladding of aluminium foil 3, and the tension braiding layer 2 is directly sleeved on wire group On, the wire 4 includes polyolefin insulation layer 41 and conductive metal core 42, and in the polyolefin insulation layer 41 conductive gold is coated on On category core 42, helicla flute 411 and annulus finishing 412 are also provided with the polyolefin insulation layer 41, the polyolefin insulation is protected There is the depth in gap, the helicla flute 411 and annulus finishing 412 between sheath 1 and tension braiding layer 2, accounts for polyolefin exhausted The 3/5 of the thickness of edge layer 41, the helicla flute 411 and annulus finishing 412 are arranged on the outer surface of polyolefin insulation layer 41, described Length of the polyolefin insulation layer 41 per 5mm-8mm, is provided with an annulus finishing 412.

The utility model replaces traditional polyvinyl chloride insulation layer, so that netting twine exists by adopting polyolefin insulation layer During burning, substantial amounts of black smoke and toxic gas will not be also produced；The utility model is also by the polyene in single netting twine On hydrocarbon insulating barrier, easy-peel helicla flute and annulus finishing are opened up, so that the wiring work of netting twine is convenient.

Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality Scheme after type simple transformation belongs to protection domain of the present utility model.
