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 unsettled erection especially, 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.
The cross section of the connector that weight body and optical cable body form is the structural design of the figure of eight, namely the linkage section between weight body and optical cable body is relatively thin, like this, the present invention need through walls or tiling lay time, by to tear or optical cable body is separated with weight body by the thinnest point of figure of eight structure by the mode such as cutting, above structure makes the present invention be convenient to built on stilts to lay and tiling is laid, the installing space tiled when laying under operating mode occupied by the present invention can be reduced simultaneously, be beneficial to as the more optical cable body of parallel lay-up in penetration pipe, or through wallsly require less boring aperture when laying.
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, the structure linkage section between weight body and optical cable body being arranged convection current lacuna is adopted, make the present invention after completing erection, when applying to unsettled erection especially, 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, the cross section of the connector that weight body and optical cable body form is the structural design of the figure of eight, namely the linkage section between weight body and optical cable body is relatively thin, like this, the present invention need through walls or tiling lay time, by to tear or optical cable body is separated with weight body by the thinnest point of figure of eight structure by the mode such as cutting, above structure makes the present invention be convenient to built on stilts to lay and tiling is laid, the installing space tiled when laying under operating mode occupied by the present invention can be reduced simultaneously, be beneficial to as the more optical cable body of parallel lay-up in penetration pipe, or through wallsly require less boring aperture when laying.
