For the problems referred to above, a kind of self-support cable structure that the utility model provides solves problem by following technical essential: a kind of self-support cable structure, comprise the optical cable body and weight body that be arranged in parallel, described optical cable body comprises integument and is embedded in the fiber body in integument, described weight body comprises sheath and is embedded in the head-rope in sheath, described sheath is connected by linkage section with integument, described linkage section is also provided with multiple convection current lacuna, described convection current lacuna distributes along the length direction of linkage section;
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 utility model 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 utility model windage size in use; Meanwhile, air-flow through the vibrations that produce on the utility model during convection current lacuna, is beneficial to rain, disengaging that snow, fog weather descend to be attached to water droplet, ice crystal etc. on the utility model surface.
Adopt and 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 utility model, reduce fiber body distortion in use, be beneficial to ability to communicate of the present utility model; 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 utility model 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 utility model 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 utility model windage size in use; Meanwhile, air-flow through the vibrations that produce on the utility model during convection current lacuna, is beneficial to rain, disengaging that snow, fog weather descend to be attached to water droplet, ice crystal etc. on the utility model surface.
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 utility model, reduce fiber body distortion in use, be beneficial to ability to communicate of the present utility model; Meanwhile, this structure is also convenient to the installation form of fixed fiber body.
