Abstract
The utility model relates to the field of communication optical cables, in particular to a self-supporting optical cable for communication and transmission. The self-supporting optical cable comprises a supporting element; the supporting element is connected with an optical cable through a connecting sling; the optical cable is provided with an outer sheath; the outer sheath is extended and connected with the supporting element; and the supporting element is formed by wrapping the sheath outside a steel wire. The optical cable and the supporting element are connected into a whole; the self-supporting optical cable is laid overhead and outdoors, and is convenient to install and construct; and after the optical cable is separated from the supporting element, the optical cable can directly enter a room and serve as an indoor optical cable and is laid indoors, so the optical cable is fast and convenient to convert.
Description
Technical field
The utility model relates to the communications optical cable field, specifically refers to a kind of self-support cable.
Background technology
Along with development of Communication Technique, the application of optical cable is increasingly extensive.The system of laying of optical cable includes pipeline, direct-burried and built on stilts laying.Along with optical fiber in the Access Network extends to user side gradually, Fiber to the home, and network is developed rapidly, and the optical fiber cable demand that adapts with it also increases rapidly.Because this type optical cable transmission range is shorter,, adopt built on stilts method of laying usually for ease of installing and inserting.In the prior art, when making somebody a mere figurehead laying optical cable, the mode that mostly adopts discrete supporting member to hang optical cable; This has brought inconvenience to laying installation: for addressing the above problem, developed a kind of incorporate self-support cable, it is linked into one by supporting member, connection suspender belt and optical cable and constitutes; For avoiding optic fibre force in the built on stilts optical cable of installing; Connecting band is arranged to discontinuous, and the optical cable between every section connecting band stays certain crooked surplus length, though this brings convenience to laying installation; But the comparatively trouble of make, and consumptive material comparatively.
The utility model content
The utility model purpose is to solve the deficiency of existing optical cable installation inconvenience, and a kind of self-support cable of simple in structure, dependable performance is provided.
The utility model self-support cable includes supporting member, and said supporting member connects suspender belt through one and connects an optical cable, and wherein said optical cable is provided with oversheath, and said oversheath extends and supporting member joins, and said supporting member is overmolding to a sheath by the steel wire outside and constitutes.
The downside of said sheath be connected suspender belt and link to each other, the lower end that connects suspender belt is connected with optical cable, the parallel extension arranged side by side with supporting member of optical cable connects suspender belt for connection shape continuously or for being interrupted equi-spaced apart connection shape.
Said optical cable includes oversheath and sleeve pipe, lays the optical fiber that leaves at least 0.3% surplus length in the sleeve pipe, also installs water-blocking component in the sleeve pipe.
The beneficial effect of the utility model is: optical cable and supporting member are connected as a body, and outdoor built on stilts laying, installation is convenient, and after optical cable and supporting member were separated, optical cable directly in the inlet chamber, as inside cable, laid indoor, changes simple and convenient; Cable outer sheath and sleeve pipe etc. join with straight configuration and supporting member; And optical fiber leaves surplus length, so not only is convenient to make, and economizes material; Good looking appearance; The structure setting is more reasonable, and can make optical fiber in the built on stilts optical cable that lays avoid the effect of external force and tension force equally, keeps its excellent communications transmission performance.
Description of drawings
Fig. 1 is the perspective view of the utility model;
Fig. 2 is the cross-sectional structure synoptic diagram of the utility model.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Be to be understood that practical implementation instance described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Consult Fig. 1, shown in 2, be the embodiment of the utility model, include a supporting member 1; Supporting member can coat a sheath 4 that constitutes by steel wire 5 or other tinsel outside and constitute, and steel wire or other tinsel can be sub-thread or strands forms, supporting member also can adopt nonmetallic materials such as nylon fiber, FRP to coat sheath to constitute; The downside of sheath 4 be connected suspender belt 2 and link to each other, the lower end that connects suspender belt 2 is connected the parallel extension arranged side by side with supporting member of optical cable with an optical cable 3; Connecting suspender belt 2 is to connect shape continuously, or connects shape for being interrupted equi-spaced apart, and optical cable is conventional cable configuration; Include oversheath 6 and sleeve pipe 7, lay the optical fiber 8 that leaves length surplus in the of 0.3% in the sleeve pipe, promptly than sleeve pipe overlength 0.2%; Also can install water-blocking component 9 in the sleeve pipe, water-blocking component can be made up of waterstop or water blocking yarn, oversheath 6 be connected suspender belt 2, supporting member sheath 4 is connected as a body; Process by fire proofing such as PVC, low-smoke halogen-free polyolefin, so that possess stronger fire resistance after in the optical cable inlet chamber.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
Claims (3)
