Background technology
Fiber optic cable industry is the second largest industry being only second to automobile industry in China, and the fiber optic cable gross output value has exceeded the U.S., becomes the first big fiber optic cable manufacturing country in the world.
Along with the progress of informationized society, the application of optical cable is more and more extensive, according to the profile of optical cable, is broadly divided into circular optical cable and square optical cable.Common square optical cable does not aim at the design that opposing extruding is carried out, and is using or during track laying construction, is being easily subject to the extruding in the external world and occurs the strain of optical fiber to affect its transmission performance.
Utility model content
This utility model, mainly solving the technical problems that provide the optical cable of entering the room of a kind of anti-extrusion, promotes the performance that optical cable is anti-extrusion.
For solving above-mentioned technical problem; the technical scheme that this utility model uses is: provide the optical cable of entering the room of a kind of anti-extrusion; including: the optical fiber inclusion body of outer protective jacket and square-section; described outer protection is set on the outside of optical fiber inclusion body; it is provided with elastic cord breaker between described outer protective jacket and optical fiber inclusion body; described optical fiber inclusion body is provided with two optical fiber core; described optical fiber inclusion body is provided with the ellipse hole between two optical fiber core, described ellipse hole is provided with elastic obturator.
In one preferred embodiment of this utility model, described elastic cord breaker and elastic obturator are non-woven fabrics or soft rubber.
In one preferred embodiment of this utility model, the outside of described optical fiber core is respectively arranged with optical fiber tight sleeve layer.
In one preferred embodiment of this utility model, described optical fiber inclusion body is provided with reinforcement core body.
In one preferred embodiment of this utility model, the described top surface of optical fiber inclusion body and the middle part of lower surface are respectively arranged with triangular groove, and described optical fiber core is between two triangular grooves.
The beneficial effects of the utility model are: the optical cable of entering the room of a kind of anti-extrusion that this utility model is pointed out; when outer protective jacket is extruded by external force; the buffering first passing around elastic cord breaker just can be delivered to optical fiber inclusion body; when optical fiber inclusion body is extruded by external force; ellipse hole and elastic obturator deformation carry out buffering and the opposing of extruding force; reduce the stress of optical fiber core, reduce optical fiber core damage in extruding, promote the service life of optical cable.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of optical cable one preferred embodiment of entering the room of a kind of anti-extrusion of this utility model.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, this utility model embodiment includes:
A kind of optical cable of entering the room of anti-extrusion; including: the optical fiber inclusion body 3 of outer protective jacket 1 and square-section; described outer protective jacket 1 is arranged on the outside of optical fiber inclusion body 3; it is provided with elastic cord breaker 2 between described outer protective jacket 1 and optical fiber inclusion body 3; described optical fiber inclusion body 3 is provided with two optical fiber core 5; the outside of described optical fiber core 5 is respectively arranged with optical fiber tight sleeve layer 51, and optical fiber tight sleeve layer 51 can promote the protectiveness of optical fiber core 5, reduces the damage of optical fiber core 5.
The ellipse hole 31 being provided with between two optical fiber core 5 in described optical fiber inclusion body 3, is provided with elastic obturator 4 in described ellipse hole 31.Outer protective jacket 1 uses low smoke halogen-free flame-retardant polyolefin plastics; insulation and good waterproof performance; when outer protective jacket 1 is extruded by external force; the buffering first passing around elastic cord breaker 2 just can be delivered to optical fiber inclusion body 3; optical fiber inclusion body 3 is flame Retarding Polyvinyl Chloride Plastics, and when optical fiber inclusion body 3 is extruded by external force, ellipse hole 31 and elastic obturator 4 deformation carry out buffering and the opposing of extruding force; reduce the stress of optical fiber core 5, thus reduce the optical fiber core 5 damage in extruding.
Described elastic cord breaker 2 and elastic obturator 4 be non-woven fabrics or soft rubber, non-woven fabrics or soft rubber when being impacted, impact can be buffered and disperses, restorative good, promote the ability that the shock resistance of entirety deforms.
Described optical fiber inclusion body 3 is provided with reinforcement core body 6, strengthens core body 6 and bond rod or finer wire for glass fibre, lightweight, promote the resistance to tension of optical fiber inclusion body 3.
The described top surface of optical fiber inclusion body 3 and the middle part of lower surface are respectively arranged with triangular groove 32, described optical fiber core 5 is between two triangular grooves 32, triangular groove 32 is conducive to the split of optical fiber inclusion body 3, it is achieved the taking-up of optical fiber core 5, lifting construction convenience.
In sum, the optical cable of entering the room of a kind of anti-extrusion that this utility model is pointed out, utilize recoverable deformation to improve the buffering to extruding and resistance, decrease the optical fiber core 5 damage in bending and extrusion process, use more stable.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
