Embodiment:
Referring to Fig. 1, a kind of nonmetallic ruggedized fiber optic cable of pipeline, including cable set 1, flame-retardant layer 4, branch are present embodiments provided
Support bone rack-layer 3 and cable core 2.The shape of cable core 2 be cylinder, along cable core 2 radial direction from inside to outside, cable core 2, support frame
Layer 3, flame-retardant layer 4 and cable set 1 are set gradually.
Support rib rack-layer 3 be right prism set, 2 sets of cable core in support rib rack-layer 3, the outer wall of cable core 2 is tangential on support rib
The inner wall of rack-layer 3, and the incline of support rib rack-layer 3 is parallel to the axis of cable core 2.Radial outside of the support rib rack-layer 3 from cable core 2
Cable core 2 is protected.The outer wall of cable core 2 and the inner wall of support rib rack-layer 3 surround No.1 filler cavity 5, No.1 filler cavity 5
It is interior to be filled with reinforcement filler.Compared to the existing stratiform support construction being directly attached on 2 outer wall of cable core, using with 2 shape of cable core
Different right prism sets enables to pipeline mainly to be born by support rib rack-layer 3 with nonmetallic ruggedized fiber optic cable stress, and
The mode that non-native cable core 2 is born, enhances the pipeline intensity of nonmetallic ruggedized fiber optic cable.Right prism set compares pipe sleeve simultaneously
More rigid, ability to bear is more preferable.Reinforcement filler can also further enhance the intensity between cable core 2 and support rib rack-layer 3.
Preferably, right prism set is regular prism set, and right prism set is rectangular sleeve in the present embodiment.The outer wall of cable core 2 is tangent
It is extruded on the inner wall of flame-retardant layer 4 in all inclines of all inner walls of rectangular sleeve, support rib rack-layer 3.The structure makes directly
Prism nested structure is more symmetrical, at the same right prism set single incline it is not too large to the inner wall support force of support rib rack-layer 3 with
The inner wall for causing damage casing play 3, too small will not be not enough to support rib rack-layer 3.
The shape of flame-retardant layer 4 is tubulose, and support rib rack-layer 3 is arranged in flame-retardant layer 4, and the incline of support rib rack-layer 3 squeezes
On the inner wall of flame-retardant layer 4.When flame-retardant layer 4 is by external force from 4 radial outside of flame-retardant layer, by support rib rack-layer 3 from resistance
The radially inner side of combustion layer 4 is supported support rib rack-layer 3, reduces the deformation of flame-retardant layer 4, in a disguised form increases pipeline with non-gold
Belong to the mechanical strength of ruggedized fiber optic cable.
In addition, the outer wall of support rib rack-layer 3 and the inner wall of flame-retardant layer 4 surround No. two filler cavitys 6, No. two filler cavitys 6
Inside it is also filled with reinforcement filler.Reinforcement filler in No. two filler cavitys 6 enhances between support rib rack-layer 3 and flame-retardant layer 4
Mechanical strength, support effect of the Auxiliary support casing play 3 to flame-retardant layer 4.
