Abstract
The utility model discloses a kind of Kuai Jie branch dry fiber optic cables, comprise a central reinforce member being positioned at optical cable center, be coated on oversheath on central reinforce member and some sub-optical cables, the outside surface circumference interval of described oversheath is furnished with several C type grooves; Sub-optical cable of the present utility model is the C type groove being directly connected in oversheath, dismounting and assembling simple, quick, the branch of optical cable can be realized rapidly, and when being separated not easily antithetical phrase optical cable itself cause damage, while guarantee each sub-optical cable transmitting light signal, improve construction speed.
Description
Technical field
The utility model relates to a kind of branched cable, needs, by the occasion of light signal multi-branch transport, to belong to technical field of photo communication when particularly relating to a kind of laying.
Background technology
Along with the development of the communications industry, optical cable is widely used in all trades and professions relating to signal, as cable TV network, GMS network, cdma network etc.And the requirement in signal broadband is constantly risen along with the continuous growth of wideband switch-in business and people, increasing occasion adopts intelligent acess, and the branch therefore for optical cable requires more and more higher.
Branched cable conventional at present has Chinese invention patent application, and publication number is CN 1916680A, and name is called bundling type branched optical cable, and this optical cable is by being undertaken boning realizing by adjacent optical cable subelement, but in production run, yield rate is not high.In addition, because bond distance is shorter, therefore in construction through several times twisting after, very easily make each subelement be separated from each other, so impact identify.Another kind is Chinese invention patent application; publication number is CN 2800302Y; name is called parallel units of branched optical fiber cable; many optical cable subelements are realized the function of branch by the connection of connecting band between adjacent; connecting band has usually and tears mouth, it makes each subelement be separated from each other by tearing mouth, but during tearing movement; the restrictive coating of easy damage subelement, and then affect the protection of its sub-unit inner fiber.
Summary of the invention
The utility model object is: provide a kind of Kuai Jie branch dry fiber optic cables, its sub-optical cable is the C type groove being directly connected in oversheath, dismounting and assembling are simply, fast, the branch of optical cable can be realized rapidly, and be separated time not easily antithetical phrase optical cable itself cause damage, while guarantee each sub-optical cable transmitting light signal, improve construction speed.
The technical solution of the utility model is: a kind of Kuai Jie branch dry fiber optic cables, comprise a central reinforce member being positioned at optical cable center, be coated on oversheath on central reinforce member and some sub-optical cables, the outside surface circumference interval of described oversheath is furnished with several C type grooves, and described sub-optical cable is clamped in C type groove respectively.
Further, the outside surface of described oversheath is provided with concave, convex identification lines, and the utility model is sorted by the difference of the concave, convex identification lines on oversheath, to identify each sub-optical cable.
The concrete structure of described sub-optical cable is: described sub-optical cable comprises sheath, is provided with tight tube fiber in sheath, is filled with nonmetal reinforcement material between described tight tube fiber and sheath.Wherein, described nonmetal reinforcement material is aramid fiber, and its effect is the longitudinal water-blocking effect for ensureing sheath, and increases the longitudinal tensile strength of optical cable.Adopt these nonmetal reinforcement materials, the compatibility of itself and tight tube fiber can be met, and can not influence of fading be produced.Described sheath adopts low smoke halogen-free flame-retardant polyolefin (LSZH) material to make;
Further, described central reinforce member is made up of multi-strand wire rope or FRP material; Described oversheath adopts low smoke halogen-free flame-retardant polyolefin (LSZH) material to make.
The utility model has the advantages that:
1, sub-optical cable of the present utility model is the C type groove being directly connected in oversheath, dismounting and assembling simple, quick, the branch of optical cable can be realized rapidly, and when being separated not easily antithetical phrase optical cable itself cause damage, while guarantee each sub-optical cable transmitting light signal, improve construction speed.
2, the whole optical cable of the utility model is dry construction, without any ointment, and convenient construction.
3, the sequence of the difference by the concavo-convex identification lines on oversheath of the present utility model identifies each sub-optical cable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is schematic cross-section of the present utility model.
Wherein: 1 central reinforce member;
2 oversheaths; 21C type groove; 22 recessed identification lines; 23 convex identification lines;
