Description
Technical field
Technical field of optical fiber communication is the utility model is related to, more specifically to a kind of anti-twist stretch-proof optical fiber.
Background technology
Optical fiber is used for the communications field, gradually well known；Meeting when optical fiber is noted that excessive bending when in use
Fractureed so that interior lights are slim；Mostly simply simple increase outer protective jacket intensity is overall antitorque to improve for the optical fiber used at present
Bent tensile resistance, monolayer composite protection effect is poor, and needs to be changed after outer protective jacket appearance breakage, can not continue
Use.
Utility model content
The technical problems to be solved in the utility model is, for the drawbacks described above of prior art, there is provided a kind of multilayer is prevented
Shield, the anti-twist stretch-proof optical fiber that outer protective jacket breakage may continue to use and anti-twist stretch-proof effect is good.
Technical scheme is used by the utility model solves its technical problem：
Construct a kind of anti-twist stretch-proof optical fiber, including protective case and optical fiber body；Wherein, in addition to the parcel optical fiber body
Inner sleeve, the inner sleeve tube outer surface, which is uniformly distributed, is fixedly installed three connection straps；The connection strap deviates from the inner sleeve
Pipe one end is fixedly connected with the protective case inwall；The inner sleeve tube outer surface is additionally provided with symmetrical one by one with the connection strap
Buffer bar, gap be present between the buffer bar and the protective case；Wire is provided with the protective case；The protective case
Outer surface is provided with fireprotection layer.
Anti-twist stretch-proof optical fiber described in the utility model, wherein, gap between the buffer bar and the protective case
Inside it is provided with insect-proof agent.
Anti-twist stretch-proof optical fiber described in the utility model, wherein, the wire is uniformly set in the protective case
It is equipped with multiple.
The beneficial effects of the utility model are：By setting wire to improve overall tensile strength in protective case；It is logical
Cross setting fireprotection layer and improve overall high temperature resistant property；, still can be after even if protective case aging or breakage by setting inner sleeve
It is continuous to use；When there is bending, the power of bending is conducted to inner sleeve by connection strap on protective case, and inner sleeve is deformed upon to slow
Rush bar to contact with protective case inwall, carry out buffering for the first time and scattered stress, then buffer bar, which is squeezed, deforms upon, and carries out the
Secondary buffer and scattered stress, greatly enhance overall torsional resistance, fiber optic protection effect is good；Overall structure is simple, and cost is low.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below in conjunction with accompanying drawing and reality
Applying example, the utility model is described in further detail, and drawings in the following description are only the section Example of the present invention, for this
For the those of ordinary skill of field, on the premise of not paying creative work, it is attached other can also to be obtained according to these accompanying drawings
Figure：
Fig. 1 is the anti-twist stretch-proof optical fiber sectional view of the utility model preferred embodiment.
Embodiment
In order that the purpose, technical scheme and advantage of the utility model embodiment are clearer, below in conjunction with this practicality
Technical scheme in new embodiment carries out clear, complete description, it is clear that described embodiment is portion of the present utility model
Divide embodiment, rather than whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art are not paying creation
Property work on the premise of the every other embodiment that is obtained, belong to the scope of protection of the utility model.
The anti-twist stretch-proof optical fiber of the utility model preferred embodiment is as shown in figure 1, including protective case 1 and optical fiber body 2；
Also include the inner sleeve 3 of parcel optical fiber body 2, the outer surface of inner sleeve 3, which is uniformly distributed, is fixedly installed three connection straps 30；Connection strap
30 are fixedly connected away from the one end of inner sleeve 3 with the inwall of protective case 1；The outer surface of inner sleeve 3 is additionally provided with and a pair of connection strap 30 1
, gap be present between buffer bar 31 and protective case 1 in the buffer bar 31 of title；Wire 10 is provided with protective case 1；Outside protective case 1
Surface is provided with fireprotection layer 4；By setting wire 10 to improve overall tensile strength in protective case 1；By setting fireprotection layer 4
Improve overall high temperature resistant property；By setting inner sleeve 3, even if the aging of protective case 1 or breakage, can still be continuing with；When
The power of bending is conducted to inner sleeve 3, inner sleeve 3 by connection strap 30 when there is bending, on protective case 1 deforms upon to buffer bar
31 contact with the inwall of protective case 1, carry out buffering for the first time and scattered stress, and then buffer bar 31, which is squeezed, deforms upon, and carries out
Second of buffering and scattered stress, greatly enhance overall torsional resistance, fiber optic protection effect is good；Overall structure is simple, cost
It is low.
As shown in figure 1, insect-proof agent 32 is provided between buffer bar 31 and protective case 1 in gap, in protective case 1 by insects
Or muroid is gnawed and protected when biting destruction, protection effect is good.
As shown in figure 1, wire 10 is evenly arranged with multiple in protective case 1, overall tensile resistance is good.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
