Description
Technical field
The utility model relates to fiber optic cable communications technical field more particularly to a kind of reinforced optical cables.
Background technique
Common optical cable includes the reinforcer, inner sheath and oversheath being sequentially arranged from inside to outside, reinforcer and inner sheath
Between be equipped with gasket for packing and cable core, can also be arranged between inner sheath and oversheath enhancement layer promoted integral strength.But this knot
The optical cable of structure in underground laying, be easy sneered by toys such as mouse break by the teeth it is bad, and optical cable be laid in it is frequent in wagon flow
When under road surface, situations such as optical cable frequently by biggish pressure, is squeezed frequent occurrence between reinforcer and cable core, rubbed, cable core
It is easy breakage, influences communication quality.
203396997 U of Chinese patent Authorization Notice No. CN, authorized announcement date 2014.01.15, a kind of entitled " non-gold
Belong to layer and cut with scissors formula fire resistant optical communication cable for coal mine ", it discloses a kind of using fire-retardant cable cream, fire-retardant oxygen barrier layer and flame retardant sheath layer cooperation
The optical cable used improves the flame retardant property of optical fiber, but cannot prevent toy from sneering and sting, and can not solve to be laid under road surface
There are problems that squeezing, rubbing etc. between reinforcer and cable core in optical cable destroying.
Utility model content
It is difficult to toy is defendd to sneer the purpose of this utility model is to overcome optical cable in the prior art to sting, be laid in road surface
Under optical cable in the serious problems such as there are reinforcer and cable cores to squeeze, friction deficiency, providing one kind can defend toy to sneer
It stings, and the reinforced optical cable of the situations such as extruding, friction between reinforcer and cable core in the optical cable being laid under road surface can be mitigated.
To achieve the goals above, the utility model uses following technical scheme:
A kind of reinforced optical cable, including center reinforcemen, inner sheath, oversheath and several cable cores, the center are reinforced
Part is equipped with annular inflatable layer, and cable core is circumferentially sequentially distributed along the outer wall of annular inflatable layer；
At least one is gasket for packing in the cable core, remaining cable core is Loose tube, is equipped with optical fiber, cable core position in Loose tube
At least one layer of aramid fiber resin braiding layer is equipped in inner sheath, between inner sheath and oversheath.Annular inflatable layer plays buffering
Effect, in relatively conventional technology reinforcer directly with cable core rigid contact, in the utility model, when optical cable is by external force, annular
Airflow layer can generate deformation energy-absorbing, make between center reinforcemen and cable core formed be elastically engaged, effectively reduce center reinforcemen with
Compressing and rubbing against between cable core.Especially when optical cable is laid in below road, the cushioning buffer effect of annular inflatable layer can
Effectively guarantee the stability of optical cable work.At least one layer of aramid fiber resin braiding is provided between inner sheath and oversheath
Layer, compared to the aramid yarn layer in routine techniques, aramid fiber resin braiding layer globality is more preferable, and intensity is higher, and toy is difficult
To gnaw through, toy is effectively prevent to destroy.
Preferably, the aramid fiber resin braiding layer is woven by more band-like aramid fiber resins.From figure
At an entirety, intensity is more preferable, can prevent toy from baiting.
Preferably, the ratio between the thickness and the thickness of inner sheath of the oversheath are 1.2 ~ 5:1.Underground environment is more multiple
Miscellaneous, the thickness for increasing oversheath is conducive to optical fiber steady operation.
Preferably, being fitted closely between the cable core and annular inflatable layer, fitted closely between two neighboring cable core.Knot
Structure is more compact, is conducive to annular inflatable layer and generates buffer function.
Preferably, being filled with the cable cream that blocks water between the inner sheath and annular inflatable layer.Underground environment is moist, and block water cable
Cream and annular inflatable layer form dual waterproofing protection, prevent moisture from entering optical fiber.
The beneficial effects of the utility model are: (1) annular inflatable layer works as a buffer, when optical cable is by external force, annular is filled
Gas-bearing formation can generate deformation energy-absorbing, be elastically engaged formation between center reinforcemen and cable core, effectively reduce and add the strong part in center and cable
Compressing and rubbing against between core；(2) it is provided with multilayer aramid fiber resin braiding layer to be wrapped on inner sheath, utilizes aramid fiber
The intensity and globality of resin braiding layer form the protective layer of strength between oversheath and inner sheath, effectively defence petty action
Object, which is sneered, to be stung.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: center reinforcemen 1, inner sheath 2, oversheath 3, annular inflatable layer 4, the cable cream 5 that blocks water, gasket for packing 6, Loose tube
7, optical fiber 8, aramid fiber resin braiding layer 9.
Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of reinforced optical cable, including center reinforcemen 1, inner sheath 2, oversheath 3 and several cable cores,
The ratio between thickness and the thickness of inner sheath of oversheath are 1.2 ~ 5:1, and underground environment is complex, and the thickness for increasing oversheath is conducive to
Optical fiber steady operation.Center reinforcemen is equipped with annular inflatable layer 4, and cable core is circumferentially sequentially distributed along the outer wall of annular inflatable layer,
Annular inflatable layer can generate deformation energy-absorbing, be elastically engaged formation between center reinforcemen and cable core, effectively reduce center reinforcement
