Abstract
A light optical cable is characterized in that it uses the non-metal strengthen line as axle to arrange an inner waterproof yarn, a muffle, an outer waterproof yarn, a strengthen twisted protective muffle and a protective muffle from inner to outer, wherein, the inner waterproof yarn is at the tangent space between the non-metal strengthen line and the muffle, the outer waterproof yarn is at the tangent space between the strengthen twisted protective layer and the muffle, the tear line is at the interface between the strengthen twisted protective layer and the muffle. The invention all uses non-metal fireproof structure, to reduce the size and volume of optical cable and obtain better anti-thunder property and waterproof effect. The non-metal strengthen line and strengthen twisted protective layer can improve its anti-drawing, anti-compressing and anti-fatigue performances. The utility model can be used to maintain optical cable, or the like.
Description
Technical field
The utility model relates to the structure of optical cable, especially about a kind of lightweight cable.
Background technology
Optical cable is the passage of transmitting optical signal, generally is divided into layer-twisted type and central beam tube type by structure.With the beam tube type cable is example, the composition of its inner structure, mostly be steel belt layer, water blocking layer, sleeve pipe (containing optical fiber) to be wrapped in wherein successively, also be shaped on the steel wire of reinforcement in the sheath by outer protective sleeve, form optical cable important document---optical fiber then is suspended in the sleeve pipe that has been full of ointment.Wherein, water blocking layer is mainly used in waterproof; The steel wire of steel belt layer and reinforcement is then mainly in order to resistance to compression and support optical cable; Ointment in the sleeve pipe is to protect wherein trickle optical fiber and waterproof equally.This optical cable mainly reaches the purpose of waterproof with the cream that has of its filling, in case optical cable damages or when breaking, the overflow of ointment will cause certain influence to environment; Secondly, the unit mass of this structure optical cable is bigger; Moreover because of casing size CS is bigger, so it is also bigger to hold the space hold of unit number of fibers, promptly cable configuration seems that thick heaviness is not compact.
The utility model content
The purpose of this utility model is to disclose a kind of in light weight and lightweight cable with good resistance thunderbolt performance.The utility model is realized by following scheme: a kind of lightweight cable, comprise sheath, water blocking layer, reinforcement rope, sleeve pipe, it is characterized in that with nonmetal reinforcement rope serve as axle by from inside to outside the level internal layer water blocking yarn is set---sleeve pipe---outer water blocking yarn---the stranded sheath of reinforcement---sheath, the internal layer water blocking yarn is arranged in nonmetal reinforcement rope and the tangent gap of sleeve pipe, outer water blocking yarn is arranged in stranded sheath of reinforcement and the tangent gap of sleeve pipe, tears the interface that joins that rope is located at stranded sheath of reinforcement and sheath; Also be provided with the gasket for packing more than 1 between the sleeve pipe; Nonmetal reinforcement rope is located at the axle center of sheath; The sleeve pipe number that is built-in with optical fiber is no less than 1, and the number of internal layer water blocking yarn setting is no less than 2, and the number of outer water blocking yarn setting is no less than 2; The number of sleeve pipe and gasket for packing is all 1, or 1 sleeve pipe and the gasket for packing more than 2; Sleeve pipe is more than 2, and gasket for packing has only 1; Tearing rope places sheath interior and tangent with the stranded sheath outside surface of reinforcement.
Press the lightweight cable of the utility model scheme implementation,, not only optimize and alleviated the dimensional weight of optical cable, and obtained good anti-thunderbolt performance and total cross-section block-water effect owing to adopted the nonmetal fire-retardant clad structure of full medium.The dual structure of nonmetal reinforcement rope and the stranded sheath of reinforcement has improved tension, lateral pressure resistant, and the performance destroyed of antifatigue of optical cable.The utility model reasonable in design, suitable Access Network are rushed to repair lightguide cable link, pipe lead road, the built on stilts application that reaches direct-burried repairing circuit, arrives family and indoor leading in cable circuit.
Description of drawings
Fig. 1 is the section structure synoptic diagram of a kind of embodiment of the utility model.
Embodiment
Be further described in detail with regard to this embodiment in conjunction with the accompanying drawings.What accompanying drawing was showed is to contain the embodiment that four ferrules constitute a kind of lightweight cable, and sheath 1 is a sleeve pipe of being made by halogen-free low-smoke flame retardant material, and this sleeve pipe has good flame retardancy; The axle center of sheath 1 is provided with nonmetal reinforcement rope 2, this reinforcement rope 2 is outer to be provided with the internal layer water blocking yarn 40 that 2 (can also have 3,4,5 or n root) are wound in nonmetal reinforcement rope 2, be provided with 4 sleeve pipe 3 and 1 gasket for packings (effect of gasket for packing is to work as the number of sleeve pipe replenishing as sleeve pipe more after a little while) 6 that contain optical fiber 31 at nonmetal reinforcement rope 2 and internal layer water blocking yarn 40 synthetic peripheries, above-mentioned water blocking yarn 40 is arranged in the gap of adjacent casing 3 and the gap of sleeve pipe 3 and gasket for packing 6; 4 sleeve pipes 3 and 1 gasket for packing 6 are implemented " SZ " by certain pitch, and stranded---being stranded one section of first forward,---stopping stranded one section---carries out reverse stranding again, sleeve pipe 3 after stranded has 2 outer water blocking yarns 41 with its binding with gasket for packing 6, wherein 1 water blocking yarn 41 is arranged in the gap with the tangent sleeve pipe 3 of the stranded sheath of reinforcement 7,1 gap that then is arranged in sleeve pipe 3 and gasket for packing 6 in addition, afterwards, give coated by the stranded sheath 7 of reinforcement.Be equipped with on the interface that stranded sheath 7 of reinforcement and sheath 1 join and tear rope 5, tearing rope 5 places sheath 1 interior and tangent with stranded sheath 7 outside surfaces of reinforcement, tear rope 5 and made by polyester or aramid fiber material, its effect is to carry out the welding of fibre-optical splice for tearing sheath 1 easily.The utility model is because of the dual structure of nonmetal reinforcement rope 2 with the stranded sheath 7 of reinforcement, not only significantly strengthened the tensile strength of optical cable, and having kept the enough pliabilities of optical cable, the water blocking yarn 40,41 of sleeve pipe 3 and gasket for packing 6 and ectonexine winding has simultaneously guaranteed the block-water performance of optical cable total cross-section.Secondly, also owing to adopted the dry type stop water of the yarn wound form of lighter weight, still can satisfy the requirement of holding 12 optical fiber after making the diameter of former sleeve pipe reduce to 2mm, not only optimize the physical dimension and the weight of optical cable, and reduced material and production cost relatively by 3mm.
