Abstract
The invention relates to a round self-supporting indoor and outdoor drop cable which comprises a coated fiber, wherein the coated fiber is arranged in a tight tube coating; a reinforcing member is coated at the periphery of the tight tube coating; the exterior of the reinforcing member is provided with a sheath; a protective layer is arranged outside the sheath and connected with a cable reinforced suspension wire; and the whole cable is of a whole dry structure. The invention has the following advantages: since the cable structure is round, the round self-supporting indoor and outdoor drop cable has greatly improved cable torsion prevention performance, is convenient to install and arrange, has the advantages of favorable cable forming technology, convenience for junction, no pollution and the like, and can be directly used as the indoor and outdoor drop cable.
Description
Technical field
The present invention relates to a communications optical cable manufacturing technology, relate in particular to a kind of circular self-bearing type indoor and outdoor leading in cable.
Background technology
FTTH introduces in the section optical cable and mainly contains self-bearing type butterfly leading in cable GJYXCH type and 2 kinds of structures of GJYXFCH type at present; Mainly there is following defective in optical cable in Design and Machining and work progress; During this structural design; The groove tear edge of butterfly optical cable part is 3N ~ 10N, and the index of this tear edge has determined that the sheath of oversheath can not be very thick, fails to play the effect of protection optical fiber; After steel wire partly peeled off, the structure of butterfly optical cable was the size that 3.0mm*2.0mm has limited non-metal reinforcement member, determined the power value that it can tension can not surpass 100N; In the optical cable process, because butterfly cable intermediate groove part thickness is not very thick, the opening phenomenon can appear, yield rate is not very high; Because butterfly cable part intermediate groove thickness is not very thick, therefore construct nonstandard the time, reverse in the unwrapping wire process and can cause groove to split.
Summary of the invention
Technical matters to be solved by this invention is that a kind of be convenient to install charity, free of contamination circular self-bearing type indoor and outdoor leading in cable are provided.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
This circular self-bearing type indoor and outdoor leading in cable comprises coated fiber, and described coated fiber is inserted at tight cover coating inner; Be wrapped in stiffener around the described tight cover coating, the outside of said stiffener is a sheath, and sheath is outside equipped with protective seam; Be connected with optical cable on the said protective seam and strengthen messenger wire; Wherein whole optical cable is the dry type structure, and described protective seam and sheath are connected to locking structure, and described tight cover coating and sheath are loose structure.
Carry out site operation in order to reach, the purpose of increasing work efficiency, further, described optical cable is strengthened messenger wire and is connected with special-purpose quick coupler.
Compared with prior art, usefulness of the present invention is: this circular self-bearing type indoor and outdoor leading in cable, after its steel wire is partly peeled off; Circular optical cable is that nonmetal nonconductive optical fiber cable can satisfy indoor demand under thunderbolt or the forceful electric power occasion, because cable configuration is circular, on the antitorque commentaries on classics performance of optical cable, good lifting is arranged; Be convenient to install charity; And have good one-tenth end technology, continue conveniently, advantage such as pollution-free is availablely directly used as the indoor and outdoor leading in cable.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is the circular self-bearing type indoor and outdoor of a present invention leading in cable structural representation.
Among the figure: 1, coated fiber; 2, tightly overlap coating; 3, stiffener; 4, sheath; 5, protective seam; 6, optical cable is strengthened messenger wire.
Embodiment:
Describe the present invention below in conjunction with accompanying drawing and embodiment:
A kind of circular self-bearing type indoor and outdoor leading in cable shown in Figure 1; Comprise coated fiber 1, the protective seam 5 that tightly overlaps coating 2, the stiffener 3 that is used to provide pulling strengrth, sheath 4 and form by steel wire; Be connected with optical cable on the said protective seam 5 and strengthen messenger wire 6, wherein whole optical cable is the dry type structure, and described protective seam 5 is connected to locking structure with sheath 4; Described tight cover coating 2 is a loose structure with sheath 4; Stiffener 3 materials are aramid yarn, and there are tight cover coating 2, aramid yarn stiffener 3, low smoke and zero halogen sheath 4 three-layer protections in coated fiber 1 outside, can well protect coated fiber 1.Described optical cable is strengthened messenger wire 6 and is connected with special-purpose quick coupler, can carry out site operation, easy construction, and efficiency ratio is higher.Described coated fiber 1 is inserted in tight cover coating 2 inside, is wrapped in stiffener 3 around the described tight cover coating 2, and the outside of said stiffener 3 is a sheath 4; Sheath 4 is outside equipped with protective seam 5; Be full dielectric structure, after steel wire was partly peeled off, circular configuration was nonmetal full medium leading in cable; Can be many in thunderbolt, carry out indoor and outdoor under the occasion that forceful electric power disturbs and introduce use.
This circular self-bearing type indoor and outdoor leading in cable, after its steel wire was partly peeled off, circular optical cable was that nonmetal nonconductive optical fiber cable can satisfy indoor demand under thunderbolt or the forceful electric power occasion; Because cable configuration is circular; On the antitorque commentaries on classics performance of optical cable, good lifting is arranged, is convenient to install charity, and have good one-tenth end technology, continue convenient; Advantage such as pollution-free is availablely directly used as the indoor and outdoor leading in cable.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
