Description
Technical field
The utility model relates to a kind of technology in signal equipment field, specifically a kind of spiral flat filament armour pipe is around pouch-type
Layer-twisted type outdoor optical cable.
Background technique
With the development of communication, the case where optical cable of laying encounters adverse circumstances, is more and more, and the spoilage of optical cable can not
Obtain limited control, wherein rodent and birds are very high to the damage accounting of optical cable.
There are many aerial optical cables to be erected at wilderness field by power circuit at present, wherein being no lack of bird sanctuary and migratory bird
Migrate route.Birds like station and rest on optical cable, some like pecking optical cable.The layer structure hardness of optical cable is general at present, very
It is easy to be pipped by birds, and then influences optical cable tensile performance, make optical cable inner fiber forced breakage, communication disruption is lived to people
It impacts.
Utility model content
The utility model In view of the above shortcomings of the prior art, proposes a kind of spiral flat filament armour pipe and twists around pouch-type layer
Formula outdoor optical cable, anti-tear can sting and anti-unfirmly closing, while lateral pressure resistant ability is strong, good bending property.
The utility model is achieved through the following technical solutions:
The utility model includes the layer-twisted type cable core set gradually from inside to outside, spiral flat filament armour pipe and oversheath；
The spiral flat filament armour pipe is formed using round wire unidirectional coiling after flattening, and surface is smooth, impulse- free robustness.
The round wire is zinc-plated carbon steel wire or phosphatization carbon steel wire.
The flat filament width of the spiral flat filament armour pipe is 0.8-4.0mm, pitch 1.0-6.0mm, with a thickness of 0.3-
0.5mm is less than 0.5mm with the gap of waterstop, being capable of free extension in the biggish field of the temperature difference.
Technical effect
Compared with prior art, the utility model has the following technical effect that
1) spiral flat filament armour pipe is easily manufactured, and durability is good, and hardness is high, and area coverage is big, and it is dynamic can be effective against grinding tooth
Object is baited and birds, is suitble to outdoor application, especially field；
2) layer-twisted type cable core is after adding spiral flat filament armour pipe, and lateral pressure resistant ability is strong, and highest can bear 5000N/100mm's
Lateral pressure, while the bending property of optical cable is unaffected；It can be used in often will appear the place rolled such as road slot, it can be with direct-burried
System of laying construction.
Detailed description of the invention
Fig. 1 is the side structure schematic view of embodiment 1；
Fig. 2 is the cross-sectional structure schematic diagram of embodiment 1；
In figure: center reinforcemen 1, loose tube fiber 2, gasket for packing 3, waterstop 4, cable cream 5, spiral flat filament armour pipe 6, nonmetallic
