Abstract
The utility model is related to a kind of flame-proof cables, including center strengthening core, further include multiple ferrules around center strengthening core, wrap up the plastic-coated aluminium strip of multiple ferrules and wrap up the crust of plastic-coated aluminium strip；Crust includes the fire-resistant isinglass belt, collet, metal net layer and the pe sheath that set gradually from inside to outside；Inert gas is filled between pe sheath and collet；When optical cable catches fire; collet protects internal ferrule; internal optical fiber is avoided to blow; metal net layer keeps optical cable while higher integral strength simultaneously; there are gaps for mesh on metal net layer; inert gas can be filled, inert gas spilling puts out the expansion of open fire or limitation fire behavior at ignition point when catching fire, and the fire resistance of optical cable is substantially increased on the premise of optical cable bending performance is not destroyed.
Description
Technical field
The utility model is related to technical field of cables, more specifically to a kind of flame-proof cable.
Background technology
Extensive use and high speed development with fiber optic communication, optical cable laying it is also more and more；The optical cable used at present
Fire resistance is poor.
Utility model content
The technical problems to be solved in the utility model is, for the drawbacks described above of the prior art, provides a kind of resistance to flame
Cable.
Technical solution is used by the utility model solves its technical problem：
A kind of flame-proof cable is constructed, including center strengthening core；Wherein, multiple light around the center strengthening core are further included
The crust of fiber coating pipe, the plastic-coated aluminium strip of the multiple ferrules of package and the package plastic-coated aluminium strip；The crust include by
It is interior to the fire-resistant isinglass belt set gradually outside, collet, metal net layer and pe sheath；The pe sheath and it is described every
Inert gas is filled between hot jacket.
Flame-proof cable described in the utility model, wherein, the metal net layer is provided with multilayer, and metal mesh described in multilayer
Face is not distributed mesh on layer.
Flame-proof cable described in the utility model, wherein, the filling inert gas is provided on the pe sheath
Inflation nozzle.
Flame-proof cable described in the utility model, wherein, the pe sheath inner wall is provided with multiple entretoise annulaires；Institute
It states inflation nozzle and is provided with multiple, and multiple inflation nozzles and the entretoise annulaire are corresponded and set.
The beneficial effects of the utility model are：When optical cable catches fire, fire-resistant isinglass belt and collet are to internal optical fiber set
Pipe is protected, and internal optical fiber is avoided to blow, while metal net layer keeps optical cable while higher integral strength, on metal net layer
Mesh can fill inert gas, inert gas spilling puts out the expansion of open fire or limitation fire behavior at ignition point when catching fire there are gap
Greatly, the fire resistance of optical cable is substantially increased on the premise of optical cable bending performance is not destroyed.
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 attached drawing and reality
Applying example, the utility model is described in further detail, and the accompanying drawings in the following description is only the section Example of the present invention, for this
For the those of ordinary skill of field, without creative efforts, it is attached to can also be obtained according to these attached drawings other
Figure：
Fig. 1 is the flame-proof cable section view of the utility model preferred embodiment.
Specific embodiment
In order to make the purpose, technical scheme and advantage of the utility model embodiment clearer, below in conjunction with this practicality
Technical solution in new embodiment carries out clear, complete description, it is clear that described embodiment is the portion of the utility model
Divide embodiment rather than whole embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art are not paying creation
Property work on the premise of all other embodiments obtained, belong to the scope of protection of the utility model.
The flame-proof cable of the utility model preferred embodiment is further included as shown in Figure 1, including center strengthening core 1 in surrounding
The crust 4 of multiple ferrules 2 of heart strengthening core 1, the plastic-coated aluminium strip 3 of the multiple ferrules 2 of package and package plastic-coated aluminium strip 3；
Crust 4 includes the fire-resistant isinglass belt 40, collet 41, metal net layer 42 and the pe sheath 43 that set gradually from inside to outside；It is poly-
Inert gas is filled between ethylene sheath 43 and collet 41；When optical cable catches fire, fire-resistant isinglass belt 40 and collet 41 are right
Internal optical fiber casing 2 is protected, internal optical fiber 5 is avoided to blow, while metal net layer 42 keeps optical cable higher integral strength
Meanwhile mesh there are gap, can fill inert gas, inert gas spilling is put out bright at ignition point when catching fire on metal net layer 42
The expansion of fire or limitation fire behavior substantially increases the fire resistance of optical cable on the premise of optical cable bending performance is not destroyed.
As shown in Figure 1, metal net layer 42 is provided with multilayer, and face is not distributed mesh on multiple layer metal stratum reticulare 42；Increase
While cable strength, inert gas saturation is improved, and then improves fire resistance.
As shown in Figure 1, the inflation nozzle 430 of filling inert gas is provided on pe sheath 43；It is filled out convenient for inert gas
It fills.
As shown in Figure 1,43 inner wall of pe sheath is provided with multiple entretoise annulaire (not shown)；Inflation nozzle 430 is set
It is equipped with multiple, and multiple inflation nozzles 430 and entretoise annulaire (not shown) are corresponded and set；By entretoise annulaire by poly- second
Partition is filled interval by inflation nozzle 430, prevents optical cable respectively into multiple intervals between alkene sheath 43 and collet 41
Local damage gas leakage, while convenient for safeguarding.
It should be appreciated that for those of ordinary skills, can be improved or converted according to the above description,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
