Description
Technical field
The utility model is related to optical fiber maintenance field, it is especially a kind of in use being capable of resistance to compression, the evils such as corrosion-resistant, fire-retardant
The fiber boot used in bad environment.
Background technology
Achievement of the optical fiber as modernization science and technology, application range rapidly increases, existing optical fiber be all with optical fiber sheet as
The protective case being wholely set is generally divided into covering, the outermost layer setting nylon protective coating of optics organic-containing materials, for light
Fibre is exposed to the weather in outdoor, or tramples and be not intended to roll when use indoors, or is related in chemically corrosive environment
Application, or in use, the damage for optical fiber is quite serious in the adverse circumstances such as the environment to catch fire, in optical fiber damage
Meanwhile the waste of resource can be directly caused, generate unnecessary economic loss.
Utility model content
The purpose of this utility model is the shortcoming for above-mentioned traditional technology, and providing one kind can normally make in optical fiber
It is being added at any time in, with resistance to compression, corrosion-resistant, fire-retardant external optical fiber protective case.
In order to achieve the above object, the technical solution adopted in the utility model is：
A kind of external optical fiber protective case, protective case include Self-adhesive and protective layer, and the Self-adhesive and protective layer are integrated
Setting, Self-adhesive include the first Self-adhesive and the second Self-adhesive, and protective layer includes flame-retarded resin layer, heat insulation foam layer, steel band armor
Layer, polytetrafluoroethylene ethylene layer.
As a further improvement, the first Self-adhesive and the second Self-adhesive are arranged in protective layer both sides.
As a further improvement, flame-retarded resin layer, heat insulation foam layer, steel band armor layer, polytetrafluoroethylene ethylene layer are sequentially overlapped and set
It sets.
As a further improvement, the protective case is arranged for spiral, and it is wrapped on optical fiber.
As a further improvement, the internal diameter under protective case normality is less than the outer diameter of optical fiber.
Compared with prior art, the advantageous effect of the utility model generation is：It is arranged for spiral helicine sheet material, in later stage reality
It can be easily wrapped on optical fiber very much in, and high with anti-flammability, corrosion resistance is strong, the high advantage of crushing resistance, and
It can be to avoid optical fiber in harsh environment in use, generated harmful effect causes the waste of resource.

Attached drawing 5 is that Self-adhesive of the utility model external optical fiber protective case when being applied on optical fiber uses structural schematic diagram.
In figure：1- Self-adhesives, the first Self-adhesives of 101-, the second Self-adhesives of 102-, 2- protection bands, 201- polytetrafluoroethylene (PTFE)
Layer, 202- steel-tape armouring layers, 203- heat insulation foam layers, 204- flame-retarded resin layers, 3- optical fiber, 4- protective cases.
Specific implementation mode
The present embodiment is described further below in conjunction with attached drawing：
Attached drawing 1 and Fig. 2 are the overall structure and using state structure diagram of the utility model external optical fiber protective case, by
Attached drawing can be seen that the shape of the protective case 4 is helical form, and protective case 4 is screw type is wrapped on optical fiber 3.
Attached drawing 3 and Fig. 4 are that the first self-adhesive layer 101 of the utility model external optical fiber protective case and the second self-adhesive layer 102 are set
Set the position of protective layer 2 and protective layer be by flame-retarded resin layer, heat insulation foam layer, steel-tape armouring layer, polytetrafluoroethylene ethylene layer successively
The formation of superposition.
Attached drawing 5 is that the Self-adhesive of the utility model external optical fiber protective case is to be superposed.
As shown in Figure 3 and Figure 4, it can be seen that protective case 4 is set by Self-adhesive 1 and 2 two parts integral type of protective layer in Fig. 3
It sets, Self-adhesive 1 includes the first Self-adhesive 101 and the second Self-adhesive 102, is separately positioned on the both sides of protective layer 2, the Self-adhesive 1
Other self adhesive materials for velcro or with gum, shown in Fig. 4, the position being in contact with optical fiber 3 is sequentially overlapped setting
Flame-retarded resin layer 204, heat insulation foam layer 203, steel-tape armouring layer 202, polytetrafluoroethylene ethylene layer 201 form protective layer 2.
As shown in figure 5, in spiral wrap optical fiber 3, Self-adhesive 1 is that overlap joint mutually laminates setting.
As depicted in figs. 1 and 2, the ontology of protective case 4 is under normal conditions helical form, convenient for being wrapped on optical fiber 2, protective case
4 when not being set on optical fiber 3, and the internal diameter of protective case 4 is less than the outer diameter of optical fiber 3, in favor of being more firmly set in optical fiber 3
On.
The utility model uses the structure of more composite layers, polytetrafluoroethylene ethylene layer 201 to be used as a kind of preferable corrosion resistance material
Material solves the corrosion default that optical fiber 3 uses in corrosive environment, and setting steel-tape armouring layer 202 is to improve protective case 4
Intensity, avoid the damage of optical fiber 3 caused by rolling and trampling in use, heat insulation foam layer 203 and flame-retarded resin layer 204
Be arranged solve optical fiber 3 heat of burning things which may cause a fire disaster is kept apart first in the case where encountering burning things which may cause a fire disaster play optical fiber 3 reduce ignition source combustion
The effect of point temperature, the flame-retarded resin layer 204 being secondly arranged avoid optical fiber 3 is on fire from damaging in the case of intensity of a fire ferociousness.
It should be noted that it is clearer in order to express in figure 5, use opposite hatching to express Self-adhesive
1 overlap joint setting.
