Description
Technical field
The utility model relates to optical cable technology fields, more particularly to a kind of freeze proof anti-fracture optical cable.
Background technique
Optical cable is manufactured to meet the performance specification of optics, machinery or environment, it is to utilize to be placed in cladding sheath
In one or more optical fiber as transmission medium and the communications cable component that can use individually or in groups.Optical cable mainly by
Optical fiber (glass fiber of thin such as hair) and plastic protective sleeve pipe and plastic peel are constituted, without gold, silver, copper aluminium etc. in optical cable
Metal, general non-recovery value.Optical cable is a certain number of optical fiber according to the certain way group stranding heart, is surrounded by sheath outside, has
Outer jacket is also coated, to realize a kind of communication line of optical signal transmission.
Existing some cold districts, since temperature is low, optical cable often will appear deformation fracture during use
The case where occur, for this purpose, it is proposed that a kind of freeze proof anti-fracture optical cable.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the one kind proposed is freeze proof anti-fracture
Optical cable.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of freeze proof anti-fracture optical cable, including oversheath and four cores are designed, is enclosed on the outside of four cores
Insulating layer, the insulating layer outside is coated with inner sheath, and core, insulating layer and sheath collectively form conductor wire, described in four
It is fixedly installed elastomer strengthening core between conductor wire, rubber layer, the rubber layer inside are provided on the inside of the oversheath
It is provided with waterproof layer, filled layer is filled between the waterproof layer and multiple conductor wires.
Preferably, the insulating layer is specially polytetrafluoroethylene ethylene layer.
Preferably, the inner sheath is specially fluorine silicone rubber.
Preferably, the oversheath is specially vulcanizate.
Preferably, the waterproof layer is specially layer of polyurethane.
Preferably, the filled layer is specially glue powder polyphenyl particle.
The utility model proposes the freeze proof anti-fracture optical cable of one kind, beneficial effect is: the freeze proof anti-fracture optical cable multilayer
Protective layer, can guarantee light have good insulating properties, cold resistance, waterproofness, with anti-fracture characteristic, guarantee that optical cable will not be because
Low temperature and cause deformation to produce fracture, the filled layer of setting can guarantee that cable interior temperature will not be dropped because of extraneous Low Temperature Thermal
The case where low, optical cable bulk temperature will not reduce, and be not in optical cable bursting by freezing generation, the elastomer strengthening core of setting can be fast
Speed restores optical cable, guarantees the case where optical cable will not be broken easily.
Detailed description of the invention
