Description
Technical field
The utility model relates to the technical field of inside cable, specifically a kind of micro indoor rodent-resistant cable.
Background technology
At present as communication apparatus connection inside cable, usually also can be subject to the infringement of muroid, have a strong impact on usability and the life-span of optical cable.Optical cable protection against rodents refers under the prerequisite not endangering optical cable transmission characteristic and long-time stability, and protection optical cable is no more than the degree of regulation because of infringement that muroid causes.Because muroid front tooth is very flourishing and can constantly growth, it is by the object that bites to keep its tooth sharp, and the distinctive smell in cable jacket contained by plastics easily attracts muroid to bite.On traditional rodent-resistant cable, general employing has armouring tape, steel wire or FRP rod.Cable configuration own wt and external diameter increase thus, and cost is high, are not suitable as inside cable and use.
Summary of the invention
The purpose of this utility model is the deficiency for solving above-mentioned technology, and provide a kind of reasonable in design, structure is simple, compact, lightweight, the micro indoor rodent-resistant cable of good mechanical property.
Technical solution adopted in the utility model is: a kind of micro indoor rodent-resistant cable; comprise optical fiber, polypropylene coating, aramid yarn, tight sleeve layer, protective sleeve; it is characterized in that center is the optical fiber of 250 μm; in optical fiber surface polyacrylic acid coating ester coating; its coat diameter is 380 μm; coating outside is aramid yarn; nylon tight sleeve layer is had in aramid yarn outside; nylon tight sleeve layer external diameter is 780 μm; at the protective sleeve that nylon tight sleeve layer outside has low smoke and zero halogen material to make, protective sleeve external diameter is 2.6mm and nylon tight sleeve layer adhesion.
The utility model is reasonable in design, compact conformation, and cost is low, lightweight, use, easy to maintenance, good mechanical property, flexible, there is fire resistance and rodent-proof characteristic.Optical cable protecting sleeve is low smoke and zero halogen material, and fire resistance is good, and during burning, few cigarette, free from environmental pollution, do not have toxicity halogenation gas to release.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1, protective sleeve, 2, polyacrylate coatings, 3, optical fiber, 4, aramid yarn, 5, nylon tight sleeve layer.
Embodiment
As shown in Figure 1: a kind of micro indoor rodent-resistant cable; comprise optical fiber 3, polyacrylate coatings 2; its center is the optical fiber 3 of 250 μm; in optical fiber 3 surperficial polyacrylic acid coating ester coating 2, its coat diameter is 380 μm, and coating outside is aramid yarn 4; nylon tight sleeve layer 5 is had in aramid yarn 4 outside; nylon tight sleeve layer 5 external diameter is 780 μm, and at the protective sleeve 1 that nylon tight sleeve layer 5 outside has low smoke and zero halogen material to make, protective sleeve external diameter is 2.6mm and nylon tight sleeve layer adhesion.For the communication facilities in buildings, computing machine, the equipment etc. of switch and terminal user.
Adopt G.657 optical fiber, compared with other single-mode fibers, G.657 the distinguishing feature of optical fiber is bend-insensitive, and its bending loss is less, can ensure that micro optical cable has good bending property.The optical fiber surface polyacrylic acid coating ester coating of 250 μm, coating external diameter is 380 μm.Select proper mold, complete with coloring apparatus, ensure that the roundness of polyacrylate coatings and the accurate of outside dimension.Aramid yarn is placed outward to ensure the tensile property of optical cable in polyacrylate coatings.Extrude nylon tight sleeve layer outside aramid yarn, the external diameter of nylon tight sleeve layer is 780 μm and adopts plsitive mold manufacture.Outside nylon tight sleeve layer, extrude low smoke and zero halogen protective sleeve, there is fire resistance.In the extrusion process of protective sleeve, for ensure optical module not with protective sleeve adhesion, to suitably increase retractable cable tension force.
The utility model is reasonable in design, compact conformation, and cost is low, lightweight, use, easy to maintenance, bending property, rodent-proof characteristic and good mechanical performance, bending property and fire resistance good.
