Described weight body is two, and two weight body relative to optical cable body axisymmetricly.
Concrete, weight body is as the load-supporting part of optical cable body, adopt the structure linkage section between weight body and optical cable body being arranged convection current lacuna, make the present invention after completing erection, when applying to high-altitude erection especially, strong air stream can pass through by convection current lacuna, is conducive to reducing the present invention's windage size in use; Meanwhile, air-flow through the vibrations that produce on the invention during convection current lacuna, is beneficial to rain, disengaging that snow, fog weather descend to be attached to water droplet, ice crystal etc. on surface of the present invention.
Adopt and arrange two weight body and weight body lays respectively at the form of optical cable body both sides, in use optical cable body is stressed more even in the radial direction can to make the present invention, and the distortion in use of reduction fiber body, is beneficial to ability to communicate of the present invention; Meanwhile, this structure is also convenient to the installation form of fixed fiber body.
Further technical scheme is:
For avoiding stress to concentrate, make annexation more reliable, the surface of described linkage section is shiny surface, and the smooth surface transition of the surface of linkage section and optical cable body and weight body.
For making optical fiber body itself have certain intensity and good waterproof ability, described fiber body is also arranged with strength layer and metal sleeve.
As a kind of lightweight, comparatively soft specific constructive form, described strength layer fibrous braid, described metal sleeve is aluminum foil pipe or Copper Foil pipe.
For ease of processing and manufacturing and overall intensity, described integument, linkage section and sheath are one-piece construction.Above one-piece construction can be aging-resistant rubber.
The present invention has following beneficial effect:
1, weight body is as the load-supporting part of optical cable body, adopt the structure linkage section between weight body and optical cable body being arranged convection current lacuna, make the present invention after completing erection, when applying to high-altitude erection especially, strong air stream can pass through by convection current lacuna, is conducive to reducing the present invention's windage size in use; Meanwhile, air-flow through the vibrations that produce on the invention during convection current lacuna, is beneficial to rain, disengaging that snow, fog weather descend to be attached to water droplet, ice crystal etc. on surface of the present invention.
2, adopt two weight body are set and weight body lays respectively at the form of optical cable body both sides, in use optical cable body is stressed more even in the radial direction can to make the present invention, reduce fiber body distortion in use, be beneficial to ability to communicate of the present invention; Meanwhile, this structure is also convenient to the installation form of fixed fiber body.
