Abstract
The utility model relates to a termite resistant digital communication cable which comprises a plurality of twisted wire pairs, wherein each of the wire pairs comprises two twisted single wires; and each of the single wires comprises a solid copper wire, an insulating layer, a PVC (polyvinyl chloride) protective layer and a polytetramethylene adi (nylon 12) outer protective layer, wherein the insulating layer covers the periphery of the solid copper wire, and the PVC (polyvinyl chloride) protective layer and the polytetramethylene adi (nylon 12) outer protective layer are extruded and molded on a cable core. The termite resistant digital communication cable achieves the purpose of termite resistance by extruding a layer of nylon 12 with high hardness on the basis of the structure of a common digital communication cable with a PVC (polyvinyl chloride) jacket.
Description
Technical field
The utility model relates to a kind of telecommunication cable, relates in particular to a kind of termite-proof cable for digital communication that is used for.
Background technology
Along with the rise of broadband connections access network construction, cable for digital communication is as the desirable transmission medium of the last 100m of information superhighway and be used widely.
Termite is worldwide important pests, and in the torrid zone and subtropical zone, the termite damage is laid indoor and outdoor cable for digital communication accident and happened occasionally.Existing cable jacket is generally polyvinyl chloride (PVC) material of extrusion molding on cable core and makes, and it is easy to be subjected to the moth erosion of termite.Find that through test of many times when sheath hardness reaches Shao Shi D70 when above, termite can not be to its moth erosion.The application just is being based on the improvement of carrying out under the above-mentioned background situation.
Summary of the invention
The utility model purpose is that a kind of termite-proof cable for digital communication is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of termite-proof cable for digital communication, comprise a plurality of lines to, be coated on the sheath of described a plurality of line to periphery, each described line is to comprising the single line of two mutually stranded settings, every single line is made up of copper conductor and the insulating barrier that is coated on the copper conductor periphery, described sheath comprise extrusion molding a plurality of lines to the polyvinyl chloride sheath on the formed cable core, be extruded in the poly-lauramide sheath of described polyvinyl chloride sheath periphery.
Further, the thickness of described polyvinyl chloride sheath and poly-lauramide sheath is roughly the same.Preferably, the thickness of described polyvinyl chloride sheath and poly-lauramide sheath is 0.5mm.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage: the utility model telecommunication cable adopts conventional cable for digital communication version, extrude the higher poly-lauramide of one deck hardness (nylon 12) sheath again at the PVC sheath, can effectively reach the purpose of termite-proof moth erosion.
Description of drawings
Accompanying drawing 1 be according to technical solutions of the utility model concrete a kind of telecommunication cable of implementing;
Wherein: 1, line is right; 11, single line; 111, copper conductor; 112, insulating barrier;
2, sheath; 21, polyvinyl chloride sheath; 22, poly-lauramide sheath;
Embodiment
Below in conjunction with accompanying drawing, describe particular content of the present utility model in detail for example:
Cable as described in Figure 1, be provided with four mutually stranded lines in it to 1, each line to 1 by two single lines 11 even stranded forming mutually, every single line 11 is made up of copper conductor 111 and the insulating barrier 112 that is coated on copper conductor 111 peripheries, four lines are arranged in order in the direction of the clock to 1, thereby are twisted into the cable core of cable; Extruding a layer thickness by line outside to 1 cable core that is twisted into is 0.5mm polyvinyl chloride sheath 21, extrude a layer thickness in polyvinyl chloride 21 peripheries and also be the poly-lauramide sheath 22 of 0.5mm, described polyvinyl chloride sheath 21 and poly-lauramide sheath 22 constitute the sheath 2 of cable core.
Described polyvinyl chloride is PVC, and described poly-lauramide is commonly called as and is nylon 12, and it has high shore hardness, by extruding one deck nylon 12 sheaths again outside the PVC sheath, thereby can reach termite-proof purpose.
More than specific embodiment of the present utility model is illustrated and illustrates, but the utility model is not only limited to above embodiment, be not limited to four as the right number of line, the PVC jacket thickness is not limited to 0.5mm, the thickness of nylon 12 sheaths is not limited to 0.5mm, termite-proof material is not limited to nylon 12, also can comprise nylon 14 or add PE sheath of termite-proof master batch etc.All equivalent transformations of doing according to the utility model all should be within protection range of the present utility model.
