Abstract
The utility model provides a communication cable, is equipped with a plurality of elastomers to interior outer jacket, voltage resistance, interior sheath, the sinle silk of including in proper order outside from between outer jacket and the voltage resistance, and the quantity of sinle silk is one at least, and the outer equal cladding of every sinle silk has the insulating layer, is equipped with the heat preservation between voltage resistance and the interior sheath, and the packing has polyester fiber in the space between the elastomer. The utility model provides a communications cable has set up voltage resistance to set up the elastomer between voltage resistance and outer jacket, made the communications cable under the effect of external force, because elastomer and voltage resistance's buffering, dispersive pressure's effect make the outer wall of the communications cable to resume fast, had higher compressive property, additionally, the utility model discloses be equipped with the heat preservation between voltage resistance and interior sheath, the temperature that can guarantee the sinle silk does not receive ambient temperature's influence, does benefit to the life who improves the whole communications cable.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of telecommunication cable.
Background technology
Along with the progress of science and technology, the communications industry obtains larger development, and the application of telecommunication cable is also more and more extensive; Telecommunication cable is the cable for transmitting phone, telegram, fax paper, TV and broadcast program, data and other signals of telecommunication, it comprises cable core and is positioned at the outer jacket outside cable core, its mounting means has built on stilts, the multiple system of laying such as direct-burried, pipeline and the bottom, in conventional art, some telecommunication cable existence being laid on below road surface are stressed larger, easily be pressed down, impact normally uses.
CN104733131A discloses a kind of resistance to compression telecommunication cable, comprise pvc sheath layer, Teflon Withstand voltage layer is provided with in described pvc sheath layer, inner restrictive coating is provided with in described Teflon Withstand voltage layer, optical fiber is provided with in described inner restrictive coating, multiple polyolefin elastomer is provided with between described pvc sheath layer and Teflon Withstand voltage layer, although this invention makes cable not easily break by multiple polyolefin elastic physical efficiency, good springiness, recover fast, use safety is efficient, but this utility model is incubated, heat-proof quality is poor, when cold or hot area use, the useful life of cable can be caused shorter.
Summary of the invention
The purpose of this utility model be overcome prior art above-mentioned deficiency and a kind of telecommunication cable is provided, it had both had good crushing resistance, had again higher insulation, heat-proof quality, effectively can extend the serviceability of telecommunication cable.
The technical solution of the utility model is: a kind of telecommunication cable, comprise outer jacket, Withstand voltage layer, sheath, core successively from outside to inside, multiple elastomer is provided with between described outer jacket and Withstand voltage layer, the quantity of described core is at least one, each core is all coated with insulating barrier outward, is provided with heat-insulation layer between described Withstand voltage layer and sheath.
The further technical scheme of the utility model is: be filled with polyester fiber in the space between described elastomer.
Further, described core is optical fiber.
Further, described Withstand voltage layer is formed by polytetrafluoroethylmaterial material processing and fabricating.
Further, the thickness of described Withstand voltage layer is not less than the thickness of the sheath of 0.5 times.
Further, described elastomer is convex structure, and elastomeric one end is fixedly connected with outer jacket, and the elastomeric other end is fixedly connected with Withstand voltage layer.
Further, described elastomer is formed by polyolefine material processing and fabricating.
Further, described outer jacket is that styrene-butadiene rubber processing and fabricating forms, and sheath is that pvc material processing and fabricating forms.
The utility model compared with prior art has following features: the utility model is provided with Withstand voltage layer, and elastomer is provided with between Withstand voltage layer and outer jacket, make the communications cable under the effect of external force, due to elastomer and the buffering of Withstand voltage layer, the effect of dispersive pressure, make the outer wall of the communications cable can quick-recovery soon, there is higher compressive property; In addition, the utility model is provided with heat-insulation layer between Withstand voltage layer and sheath, can ensure that the temperature of core is not by the impact of ambient temperature, is beneficial to the useful life of improving the whole communications cable.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in drawings: a kind of telecommunication cable, comprise outer jacket 1, Withstand voltage layer 4, sheath 6, core 8 from outside to inside successively, multiple elastomer 2 is provided with between outer jacket 1 and Withstand voltage layer 4, the quantity of core 8 is three, core 8 is optical fiber, each core 8 is outer is all coated with insulating barrier 7, is provided with heat-insulation layer 5 between Withstand voltage layer 4 and sheath 6.
Be filled with polyester fiber 3 in space between elastomer 2, both can further improve insulation, heat-proof quality, the effect of certain compensator or trimmer pressure can be played again.
Withstand voltage layer 4 is formed by polytetrafluoroethylmaterial material processing and fabricating, has excellent heat-resisting and low temperature tolerance characteristics, under high temperature severe cold, all deformation can not occur, have good compressive property; The thickness of Withstand voltage layer 4 is not less than the thickness of the sheath 6 of 0.5 times, ensures that Withstand voltage layer 4 can provide enough pressure buffer spaces.
Elastomer 2 be convex structure, have the effect of good buffering, dispersive pressure, can make after communications cable pressurized can fast quick-recovery ortho states; One end of elastomer 2 is fixedly connected with outer jacket 1, and the other end of elastomer 2 is fixedly connected with Withstand voltage layer 4, makes the positional stability of elastomer 2 higher; Elastomer 2 is formed by polyolefine material processing and fabricating.
Outer jacket 1 forms for styrene-butadiene rubber processing and fabricating, and sheath 6 forms for pvc material processing and fabricating.
