Abstract
The utility model relates to an indoor and outdoor self-supporting composite cable which comprises a cable and a messenger wire. The cable is connected with the messenger wire through a sling. The indoor and outdoor self-supporting composite cable is characterized in that the cable is a composite cable which comprises a composite cable core and an outer sheath, and the composite cable core comprises a central reinforcing piece and a single optical fiber cable twisted at the periphery of the central reinforcing piece. According to the indoor and outdoor self-supporting composite cable, pipeline and overhead laying requirements in outdoor wiring can be satisfied, indoor bunched bulk wiring and single tube passing wiring are facilitated, the optical network connection of one node to a plurality of nodes can be realized through laying in one time, thus the construction efficiency is raised, the laying resource is saved, and the cost is saved. According to a butterfly shaped cable, the friction coefficient is low, the tube passing is facilitated, the strength is high, the bending performance is good, the branching and indoor laying are facilitated, the cable stripping and fiber separation are facilitated through a V-shaped groove structure, and the branching connection is convenient and safe. The indoor and outdoor self-supporting composite cable has the advantages of simple and compact structure, reasonable arrangement, and the laying requirements of fiber to the home can be fully satisfied.
Description
Technical field
The utility model relates to the dual-purpose self-bearing type composite cable of a kind of indoor and outdoor.
Background technology
Along with FTTH(optical fiber is registered one's residence) fast development, to the batch bunchy of optical cable use, the indoor and outdoor wiring is dual-purpose, low friction optical cable poling performance has all proposed higher requirement.When the large quantities of bunchys of existing common butterfly optical cable use, need tighten with band, not good to cable protection, use inconvenience, influence the installation progress; When the needs indoor and outdoor connected up for two times spent, need continue with outdoor optical cable, increased difficulty of construction; When the single poling of needs uses, because common butterfly optical cable size is bigger than normal, the sheath friction factor is higher, has not only reduced poling efficient, and has taken bigger pipeline space, the waste conduit resource.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and proposes the dual-purpose self-bearing type composite cable of a kind of indoor and outdoor, it can not only satisfy yard piping and the requirement of built on stilts cloth cable, and can be convenient to indoor one-tenth wiring in bundles and poling wiring.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is: include optical cable and messenger wire, optical cable links to each other with messenger wire by suspender belt, it is characterized in that described optical cable is composite cable, described composite cable comprises compound cable core and oversheath, and described compound cable core comprises central reinforce member and is stranded in the unit cable of central reinforce member periphery.
Press such scheme, described unit cable is butterfly optical cable, and described butterfly optical cable comprises the butterfly sheath and is included in 1 ~ 2 optical fiber at sheath center.
Press such scheme, the both sides of described butterfly sheath inner fiber are provided with reinforcement.
Press such scheme, described butterfly sheath radial section is rounded, and vertical V-shaped groove is offered in both sides outside sheath, constitutes the butterfly radial section thus.
Press such scheme, the reinforcement that arranges in the described butterfly sheath is steel wire, and described butterfly sheath is made less than 0.20 polyolefine material by kinetic friction coefficient.
Press such scheme, described compound cable core also includes the water-blocking component of pricking yarn and twining cable core, opens hawser in cable core one side setting.
Press such scheme, the metal armouring layer is covered in described compound cable core outsourcing, and described metal armouring layer is with or is indulged the alclad band by vertical Baogang and constitutes.
Press such scheme, described messenger wire is stranded steel wire or individual wire, and messenger wire coats outer jacket outward, and outer jacket is linked into one by suspender belt and oversheath, constitutes 8 font oversheaths.
Press such scheme, described central reinforce member is nonmetal central reinforce member.
The beneficial effects of the utility model are: 1, the inside and outside composite cable structure of integrated 8 font self-bearing types has stronger self-supporting intensity, pipeline lays requirement with making somebody a mere figurehead when not only satisfying outside run, and be convenient to that indoor bunchy connects up in batches and the wiring of single poling, can realize that a node connects to the optical-fiber network of a plurality of nodes by once laying, thereby raising operating efficiency, resource is laid in saving, reduces cost; 2, not only friction factor is low is convenient to poling for low friction butterfly optical cable, and the higher and good bending property of self intensity is convenient to branch and indoor laying, and the V-shaped groove structure is easy to optical cable baring and separates with optical fiber, and it is convenient and safe to make difference continue; 3, the utility model is simple and compact for structure, arranges rationally, and it is good to lay the difference performance, can fully satisfy the requirement of laying that optical fiber registers one's residence.
