Identified by operating personnel, facilitate the maintenance of optical cable.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of the preferred embodiment of the present invention.
Fig. 2 is the structural schematic diagram of the protective case of the present invention.
In figure：1 be optical fiber, 2 be protective case, 21 be aramid layers, 22 be metal organization level, 23 be the first polyvinyl chloride layer,
24 it is phase-change material layers, 25 be the second polyvinyl chloride layer, 26 be wearing layer, 27 be reinforcement, 3 be reinforcer, 4 is elastic hollow
Pipe, 5 be cavity, 6 be groove, 7 be that fluorescence identifying pastes, 8 is filling member.
Specific implementation mode
Presently in connection with drawings and examples, the present invention is described in further detail, these attached drawings are simplified signal
Figure, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
As illustrated in fig. 1 and 2, a kind of shock resistance optical cable, including several mutually independent optical fiber 1, protective case 2, reinforcer 3 with
And filling member 8, in the effect of filling member 8 is to be filled in when there is larger vacancy, to ensure the stabilization of optical cable；Reinforcer 3
Section is in equilateral triangle, extends along the length direction of optical cable；Optical fiber 1 and filling member 8 are set to inside reinforcer 3；It protects
Sheath 2 is wrapped in outside reinforcer 3.The setting can provide better compressive property to optical cable, this is because the knot of triangle
Structure is stablized relatively, especially equilateral triangle.Therefore section is the reinforcer of equilateral triangle, can resist more pressure
Impact, the optical fiber 1 of protection setting inside it.Rigid plastics or other conventional materials can be selected in the material of reinforcer 3.Simultaneously
Many cavitys 5 are constituted between reinforcer 3 and protective case 2, these cavitys are not filled with anything.When the impact that optical cable is subject to,
Cavity 5 is compressed, and can be played the role of buffering and be absorbed impact.
Optical cable also sets up flexible hollow tube 4.Flexible hollow tube 4 is set to optical cable center, light along the length direction of optical cable
Fibre 1 and filling member 8 are fitted closely around 4 outside of flexible hollow tube is set to flexible hollow tube 4；Between optical fiber 1, optical fiber 1
It is mutually not in contact with each other between filling member 8.This is designed with the anti-stress for being conducive to improve optical cable, when the impact that optical cable is subject to is larger,
Cavity 5 and reinforcer 3 also can not fully against when, pressure is transmitted to reinforcer 3 by protective case 2, then is transmitted to optical fiber 1, light
Fibre 1 is transmitted to flexible hollow tube 4 again, and the internal cavities of flexible hollow tube 4 are compressed, and impact can be further absorbed, to protect
Optical fiber is protected.Due to being mutually not in contact with each other between optical fiber 1, between optical fiber 1 and filling member 8, there are space, it ensure that compression process can
To be smoothed out.
The present invention is arranged by triple resistance to compressions, has carried out good protection to optical fiber 1, has extended the service life of optical fiber 1.
Protective case 2 be multilayered structure, from inside to outside include aramid layers 21, metal organization level 22, the first polyvinyl chloride layer 23,
Phase-change material layers 24, the second polyvinyl chloride layer 25 and wearing layer 26.Wherein the setting of phase-change material layers 24 can improve optical cable
Temperature tolerance.This is because when environment temperature is raised and lowered more than transformation temperature, phase-change material can be absorbed or put by phase transformation
Go out latent heat, to compensate for the variation of environment temperature, plays the role of adjusting temperature, improve the temperature tolerance of optical cable.Phase transformation material
Material selection paraffin or butyl stearate, cheap, latent heat is high.In addition in practical application, optical cable often can because of carry or
It is laid with and generates abrasion, the present invention is arranged wearing layer 26 and extends the service life of optical cable to improve the antiwear property of optical cable.
Wearing layer 26 is set as layer of polyurethane.Polyurethane has good wearability, and derives from a wealth of sources, cheap.
Reinforcement 27 is set between aramid layers 21 and metal organization level 22 simultaneously, to improve the intensity of optical cable.Reinforcement
27 can be wrapped in aramid layers 21, to save material.Reinforcement 27 is phosphatization carbon steel wire reinforcement.The material has good
Intensity and toughness are conducive to the protection to optical fiber 1.
Since optical cable is constructing and is being inevitably generated abrasion in application process, lead to the distinguishing mark on protective case
It frequently wears out smudgy, prodigious trouble is brought to the replacement maintenance of later optical cable.The present invention is in 2 appearance of protective case
The groove 6 to extend internally is arranged in face.Setting fluorescence identifying pastes 7 in groove 6.Since fluorescence identifying patch 7 is outer less than protective case 2
Surface reduces its abrasion in construction and application, the service life of fluorescence identifying patch 7 is improved, convenient for maintenance from now on
And replacement.Fluorescence identifying patch 7 still more can be identified easily by operating personnel at night or the bad place of light simultaneously, side
Optical cable maintenance.
Based on the above description of the preferred embodiments of the present invention, through the above description, related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
It is not limited to the contents of the specification, it is necessary to determine the technical scope according to the scope of the claims.
