Abstract
The utility model relates to a snakelike optical cable, a serial communication port, the optical cable includes the oversheath, be provided with the multicore subelement in the oversheath, the oversheath sets up to PPT coiled pipe sheath. The multicore subelement includes restrictive coating, aramid fiber layer in proper order and sets up the painted optic fibre in inside to interior outside from. This optical cable is snakelike optical cable, uses crooked insensitive optic fibre, and when the occasion of buckling was used, it is enough little that the assurance attachs the decay, and simultaneously, the subelement adopts low fricative sheath, cooperates the structure of cavity, and the assurance optical cable is under the condition of buckling, and the subelement has sufficient activity space in the cavity, can excessively not buckle, 3 )This technical scheme adopts PPT's coiled pipe sheath, guarantees that the optical cable bending can not continue the bending behind the minimum bending radius of design to reach the ability that superstrong bending resistance is rolled over.
Description
Technical field
The utility model is related to a kind of optical cable, more particularly, to a kind of snakelike optical cable.
Background technology
Optical cable be in order to meet optics, the performance specification of machinery or environment and manufacture, it is using being placed in cladding sheath
In one or more optical fiber as transmission medium and the communications cable component that can use individually or in groups.Optical cable mainly by
Optical fiber（The glass fiber of thin such as hair）Constitute with plastic protective sleeve pipe and plastic peel, as environment is different, apply not
It is very big with the optical cable in environment also difference, much need the occasion for repeating bending still to use in elevator, mechanical arm etc. at present and pass
The Cable Telecommunications transmission information of system, but the shortcoming of optical fiber cable frangibility is govern these occasions and is believed using optical signal transmission
Breath.Those skilled in the art repeatedly attempts new scheme, but the problem is never well solved, therefore, compel
A kind of new scheme of needs cut solves the technical problem.
Utility model content
The utility model is exactly for problem present in prior art design, there is provided a kind of snakelike optical cable, this is snakelike
Optical cable has superpower bend resistance ability, can be used for these occasions for repeating bending.
To achieve these goals, the technical solution adopted in the utility model is, a kind of snakelike optical cable, it is characterised in that
The optical cable includes oversheath, is provided with many cartridge units in the oversheath, and the oversheath is set to that PPT is snakelike to be managed and protected
Set.
Used as a kind of improvement of the present utility model, many cartridge units include restrictive coating, aramid layers from outside to inside successively
And it is arranged on the colored optical fiber of inside.
Used as a kind of improvement of the present utility model, the oversheath is set to cavity structure.The restrictive coating is cylinder
Structure, colored optical fiber quantity are 2-12 cores.
Relative to prior art, advantage of the present utility model is as follows：1）Overall construction design is novel, compact, and 2）The optical cable
For snakelike optical cable, using bend insensitive fiber, when bending occasion and using, it is ensured that additional attenuation is sufficiently small, meanwhile, subelement
Using the sheath of low friction, coordinate the structure of cavity, it is ensured that in the case of bending, subelement has enough in cavity to optical cable
Activity space, will not overflexing；3）Snakelike tube boot of the technical scheme using PPT, it is ensured that optical cable bends to design most
Bending is will not continue to after small-bend radius, so as to reach the ability of superpower bend resistance.
Description of the drawings
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is subelement cross section structure schematic diagram；
Fig. 3 is cable cross-section structural representation；
Wherein, 1, oversheath, 2, subelement, 3, restrictive coating, 4, colored optical fiber, 5, aramid layers.
Specific embodiment
In order to deepen, to understanding and cognition of the present utility model, below in conjunction with the accompanying drawings the utility model to be further described
And introduction.
Embodiment 1：Such as Fig. 1-Fig. 3, a kind of snakelike optical cable, the optical cable include arranging in oversheath 1, the oversheath
There are many cartridge units 2, the oversheath 1 is set to the snakelike tube boots of PPT, and the optical cable is snakelike optical cable, using bend-insensitive
Optical fiber, when occasion use is bent, it is ensured that additional attenuation is sufficiently small.The oversheath is set to cavity structure, is easy to subelement
It is movable in cavity.
Embodiment 2：Such as Fig. 1-Fig. 3, as it is of the present utility model it is a kind of improve, many cartridge units from outside to inside according to
It is secondary including restrictive coating 3, aramid layers 5 and be arranged on inside colored optical fiber 4, the oversheath is set to cavity structure, described
Restrictive coating 3 is cylindrical structural, and colored optical fiber quantity is 2-12 cores.Sheath of the subelement using low friction, coordinates the knot of cavity
Structure, it is ensured that in the case of bending, subelement has enough activity spaces in cavity to optical cable, will not overflexing；Using PPT
Snakelike tube boot, it is ensured that optical cable will not continue to bending after bending to the minimum bending radius of design, so as to reach superpower bending resistance
The ability of folding.
It should be noted that above-described embodiment, not for limiting protection domain of the present utility model, in above-mentioned technical side
On the basis of case, done equivalents or replacement each fall within the utility model scope of the claimed protection.
