Abstract
The utility model relates to a communication optical cable, particularly to a high dynamic bending-resistant performance optical cable. The high dynamic bending-resistant performance optical cable comprises cable core composed of a central reinforcement member, water-resisting yarn, fiber, PBTP, a gasket for packing, and wrapping yarn, a water-resisting belt, fiber yarn, inner sheath, and outer sheath. The high dynamic bending-resistant performance optical cable is characterized in that the periphery of the central reinforcement stainless steel twisted wire is provided with a coating layer; a longitudinal wrapping belt is arranged between the water-resisting belt and the inner sheath; and the inner sheath is externally provided with the fiber yarn. As the periphery of the stainless steel twisted wire is provided with a coating layer made of polyethylene material, the dynamic bending-resistant performance of the optical cable is improved. Meanwhile, the stretching performance and the anti-flattening performance of the optical cable are ensured. The adoption of plastic-aluminum composite belt with double plastic-coated faces effectively improves the mechanical performance of the optical fiber, such as the moisture-proof performance, the antirust performance, and the anticorrosion performance. The high dynamic bending-resistant performance optical cable provides reliable and beneficial technology support for data transmission in FAST telescope operation.
Description
Technical field
The utility model relates to communications optical cable, particularly about a kind of high dynamic bending resistance optical cable.
Background technology
The utility model relates to the application optical cable of a kind of FAST (the sphere radio telescopes of 500 rice diameters).FAST is a kind of radio telescope of maximum caliber in the world, and the normal operation of FAST needs great amount of data transmission, and these data need be passed through the optical cable transmission.Be to ensure the telescopical normal operation of FAST, its core cabin body is wanted the continuous three-dimensional motion of doing, and will drive the coupled communications optical cable that connects simultaneously and be synchronized with the movement, and so, optical cable will stand alternating bending, reverse and multiple complicated motion such as stretching.Above-mentioned motion has determined optical cable must possess dynamic bending resistance, higher pliability, and has higher stretching, anti-collapse and environmental resistance.And the structure of existing various general optical cables and performance all can not satisfy the requirement of FAST telescope runtime data transmission.
The utility model content
The purpose of the utility model is on the basis of existing communication cable configuration, proposes a kind of high dynamically bending resistance optical cable that is used for ensureing the normal operation of FAST telescope.
For realizing this purpose; Adopt following technical scheme: a kind of high dynamic bending resistance optical cable; Comprise the cable core, waterstop, silvalin and the inside and outside sheath that constitute by central reinforce member, water blocking yarn, optical fiber, loose sleeve pipe, gasket for packing and bundle yarn, it is characterized in that the periphery of central reinforce member stainless steel twisted wire is provided with coating; Be provided with vertical band between waterstop and the inner sheath, inner sheath is provided with silvalin outward; Coating is processed by tygon; Vertical band is two-sided plastic-coated aluminium-plastic tape; Silvalin is set to reverse twine two-layer.
Press the high dynamically bending resistance optical cable that such scheme is implemented; Owing to be provided with the coating of processing by polythene material in the periphery of stainless steel twisted wire; Not only improve the dynamic bending resistance of optical cable, guaranteed the tensile property and the anti-collapse performance of optical cable simultaneously again.Because of adopting the aluminium-plastic tape of two-sided plastic-coated, the protection against the tide of optical cable, antirust, etch-proof mechanical property have been improved significantly again.Data transmission when the utility model moves for assurance FAST telescope provides reliable and useful technical support.

Fig. 1 is the vertical profile structural representation of a kind of embodiment of the utility model;
Fig. 2 is the cross-sectional configuration synoptic diagram of Fig. 1.
Embodiment
Further specify with regard to this embodiment in conjunction with accompanying drawing.Central reinforce member is made up of 19 stainless steel twisted wires 11 and the coating 10 that is arranged at the periphery, and coating 10 is to be applied by polythene material to process; The pine casing inner diameter can be 1.8～3.6mm, in adorn 2～12 optical fiber, the loose sleeve pipe 7 of present embodiment is built-in with 12 optical fiber 8; Other parallel, the spiral of central reinforce member has many water blocking yarns 9 around the home, and the loose sleeve pipe after stranded is tied with bundle yarn 6 in the opposite direction outward, promptly constitutes the cable core of optical cable.Cable core is vertical successively outward to be surrounded by waterstop 5, can certainly place material water-proof materials such as water blocking yarn with same function or cable cream; For improving protection against the tide, antirust, the etch-proof mechanical property of optical cable, between waterstop 5 and inner sheath 3, be provided with vertical band 4, vertical band 4 is processed by two-sided plastic-coated aluminium-plastic tape, as the internal layer armor; Vertical band 4 on the one hand can be moistureproof, utilizes the pliability of aluminium plastic material can make optical cable reach less bending radius simultaneously, thereby improve the bending resistance of optical cable; Inner sheath 3 available polyethylene materials are processed.Inner sheath outward successively bilayer oppositely be surrounded with silvalin; Silvalin is nonmetal reinforcing fibre yarn 2, can be processed by aramid yarn such as silvalin, and non-metallic fibers is strengthened the outer reinforcement that yarn 2 has constituted the utility model; The setting of outer reinforcement; Improve the drawing mechanical performance of optical cable on the one hand, can be used as the bending resistance that cushion improves optical cable simultaneously, flattened performance; Outer protective sleeve 1 is employed in the tygon of non-metallic fibers reinforcement yarn 2 outer lining suitable thickness and processes.
The utility model adopts central reinforce member and non-metallic fibers to strengthen the structure of yarn outer reinforcement, and optical cable is carried out the inside and outside protection of strengthening, and has improved the mechanical property of optical cable.
