Abstract
The utility model is created and is related to communications optical cable technical field, is specifically related to the easy stripping fiber optic cables of vertical wirings.It comprises sheath, some cable cores are provided with in sheath, cable core comprises optical fiber and is sheathed on the tight cover of optical fiber, be filled with aramid fiber between cable core and sheath, also comprise oversheath and waterstop, oversheath is coated on the periphery of sheath, waterstop is arranged between oversheath and sheath, oversheath is platypelloid type, and two flat sides that oversheath is relative are respectively arranged with the V-shaped tearing groove in cross section, and the tearing groove in two flat sides is mutually wrong to setting.This vertical wirings with easy stripping fiber optic cables being arranged the wrong tearing groove of V-arrangement to arranging, the time of conveniently tearing oversheath, effectively saving optical cable construction, continuing when safeguarding.
Description
Technical field
The invention relates to communications optical cable technical field, is specifically related to the easy stripping fiber optic cables of vertical wirings.
Background technology
The optical cable of common vertical wirings, after laying during wiring, needs to strip out one section with the end of instrument to optical cable, to make cable core expose outside sheath, then the part exposed is continued.But, owing to there is no the stripping tool of the optical cable being directed to vertical wirings at present, usually need first the oversheath of optical cable to be scratched with stage property, by manually tearing, whole operating process is extremely inconvenient, thus has influence on construction speed, also can cause the inconvenience of follow-up maintenance simultaneously.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art and the easy stripping fiber optic cables of vertical wirings providing a kind of constructability, continue when safeguarding.
The object of the invention is achieved through the following technical solutions:
Provide the easy stripping fiber optic cables of vertical wirings, comprise sheath, some cable cores are provided with in sheath, aramid fiber is filled with between cable core and sheath, cable core comprises optical fiber and is sheathed on the tight cover of optical fiber, it is characterized in that: also comprise oversheath and waterstop, oversheath is coated on the periphery of sheath, waterstop is arranged between oversheath and sheath, oversheath is platypelloid type, two flat sides that oversheath is relative are respectively arranged with the V-shaped tearing groove in cross section, and the tearing groove be in respectively in two flat sides is mutually wrong to setting.
Wherein, described tearing groove is provided with two, and described two tearing grooves are about the central axis Central Symmetry of sheath.
Wherein, described oversheath is PU oversheath.
Wherein, described sheath is LSZH sheath.
The beneficial effect of the invention:
The easy stripping fiber optic cables of vertical wirings of the invention, cable core adopts tight tube structure, makes optical cable be applicable to vertical wirings use occasion, especially in mine, the use occasion that in vertical shaft, condition is more severe.Oversheath is provided with the tearing groove that cross section is V-shaped, when construction continues, as long as oversheath is torn along tearing groove the length be applicable to manually artificially, and loaded down with trivial details stripping need not be carried out with instrument, constructability and splicing cables when safeguarding.Tearing groove is separately positioned in two relative flat sides of oversheath, in wrong to setting, namely the V-arrangement tip of the tearing groove of relative both sides is not oppositely arranged, when oversheath is torn along tearing groove, the coated inner structure of oversheath can all come out, the time avoiding the problem needing because inner structure exposes not exclusively repeatedly to tear, thus reach the effect peeling off rapidly, reduce the fiber cable laying time, effectively save optical cable construction, continue when safeguarding.Oversheath is platypelloid type, makes optical cable have good resistance to compression, shock resistance.Between oversheath and sheath, be provided with waterstop, make optical cable have total cross-section block-water performance.And optical cable is dry type structure, reveals when continuing without fluid, conveniently continues, reduce laid down cost.
Accompanying drawing explanation
Accompanying drawing is utilized to be described further innovation and creation, but the embodiment in accompanying drawing does not form any restriction to the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the following drawings.
Fig. 1 is the structural representation of vertical wirings with easy stripping fiber optic cables of the invention.
Reference numeral:
1-oversheath, 11-tearing groove,
2-waterstop,
3-sheath,
4-tightly overlaps,
5-optical fiber,
6-aramid fiber.
Embodiment
With the following Examples the invention is further described.
The easy stripping fiber optic cables of vertical wirings of the invention, as shown in Figure 1, comprise sheath 3, sheath 3 is preferably LSZH sheath, to guarantee the intensity of optical cable, toughness and anti-wear performance.The periphery of sheath 3 is coated with oversheath 1, and the inside of sheath 3 is distributed with some cable cores, is filled with aramid fiber 6 between sheath 3 and cable core, is provided with waterstop 2 between sheath 3 and oversheath 1.Wherein, cable core comprises optical fiber 5 and is sheathed on the tight cover 4 of optical fiber 5.Oversheath 1 is in platypelloid type, and this setting makes optical cable have superior resistance to compression and shock resistance, and oversheath 1 is preferably PU oversheath, guarantees the anti-wear performance of optical cable.Two flat sides that oversheath 1 is relative are respectively arranged with tearing groove 11, and the cross section of tearing groove 11 is V-shaped, and the tearing groove in two flat sides is in mutually wrong to setting.Preferably, tearing groove is provided with two, and two flat horizontal surfaces respectively arrange one, and these two tearing grooves 11 are about the central axis Central Symmetry of sheath 3.
Finally should be noted that; above embodiment is only in order to illustrate the technical scheme of the invention; but not the restriction to the invention protection domain; although done to explain to the invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical scheme of the invention or equivalent replacement, and not depart from essence and the scope of the invention technical scheme.
