Description
Technical field
The present invention proposes a kind of communications optical cable manufacturing technology, particularly the circular leading in cable of a kind of enhancement mode.
Background technology
At present in the circular leading in cable structure of FTTH, existing product is house wiring GJFJH type and indoor and outdoor 2 kinds of structures of GJYFJH type, mainly there is following problem in optical cable in processing and work progress: adopt nonmetal yarn as reinforcement material in cable configuration, soft, need to adopt traction rope when cable installation in pipe, construct cumbersome; When indoor external form GJYFJH optical cable used as aerial optical cable, the colligation fixed form adopted the direct colligation of binding to be fixed on optical cable, was easy to make external force direct effect on binding wire during misoperation to optical fiber, caused fiber transmission attenuation to increase; Cable configuration is loose structure, and the contraction of jacket material and processing technology are difficult to meet optical cable in the temperature cycles of-40 degree to+70 degree, and the first-time qualification rate of product is higher.
Summary of the invention
The present invention seeks to for and provide the strong enhancement mode of the direct cable installation in pipe of a kind of energy, stretching resistance circular leading in cable.
For achieving the above object, the present invention solves the scheme that its technical matters takes and is:
The circular leading in cable of this enhancement mode, comprise the coated fiber that is positioned at optical cable central authorities, described coated fiber is extruded with tight cover coating outward, described tight cover coating is outside equipped with non-metal reinforcement member, the outer extrusion molding of described non-metal reinforcement member has low cigarette without the chimney oversheath, and described low cigarette is without being provided with enhanced non-metallic part in the chimney oversheath.
Further, described enhanced non-metallic part diameter is 0.2mm, and after coating one deck resin, diameter is 0.3mm.
Closer, described coated fiber diameter is 0.9mm or 0.6mm.
Closer, described enhanced non-metallic part number is four.
Closer, described enhanced non-metallic part number is three and is uniformly distributed.
Closer, described four enhanced non-metallic parts are symmetrical or be uniformly distributed in twos.
Compared with prior art, usefulness of the present invention is: the circular leading in cable of this enhancement mode has increased the enhanced non-metallic part with certain rigidity in sheath, when optical cable when hidden pipe lays, can be without any need for drafting tool, direct cable installation in pipe; During as aerial optical cable, increased the enhanced non-metallic part of rigidity when optical cable in the circular leading in cable sheath material of enhancement mode, can offset the External Force Acting of binding wire, played the effect of better protection optical fiber, the reliability of product is high; Indoor type and indoor external form optical cable all can meet the temperature cycles of-40 degree to+70 degree, and the qualification rate of product is high.

In figure: 1, coated fiber; 2, tightly overlap coating; 3, non-metal reinforcement member; 4, low cigarette is without the chimney oversheath; 5, enhanced non-metallic part.
Embodiment
Describe the present invention below in conjunction with the drawings and the specific embodiments:
The circular leading in cable of a kind of enhancement mode shown in Figure 1, comprise the coated fiber 1 that is positioned at optical cable central authorities, be extruded with tight cover coating 2 outside described coated fiber 1, described tight cover coating 2 is outside equipped with non-metal reinforcement member 3, the outer extrusion molding of described non-metal reinforcement member 3 has low cigarette without chimney oversheath 4, and described low cigarette is without being provided with enhanced non-metallic part 5 in chimney oversheath 4.
Described enhanced non-metallic part 5 diameters are 0.2mm, and after coating one deck resin, diameter is 0.3mm.
Described coated fiber 1 diameter is 0.9mm or 0.6mm.
Enhanced non-metallic part 5 numbers are four and are uniformly distributed as described in Figure 1.
Enhanced non-metallic part 5 numbers are four and symmetrical in twos as described in Figure 2.
Enhanced non-metallic part 5 numbers are three and are uniformly distributed as described in Figure 3.
Described four enhanced non-metallic parts 5 are symmetrical or be uniformly distributed in twos.
The circular leading in cable of this enhancement mode has increased the enhanced non-metallic part with certain rigidity in sheath, when optical cable when hidden pipe lays, can be without any need for drafting tool, direct cable installation in pipe; During as aerial optical cable, increased the enhanced non-metallic part of rigidity when optical cable in the circular leading in cable sheath material of enhancement mode, can offset the External Force Acting of binding wire, played the effect of better protection optical fiber, the reliability of product is high; Indoor type and indoor external form optical cable all can meet the temperature cycles of-40 degree to+70 degree, and the qualification rate of product is high.
It is emphasized that: above is only preferred embodiment of the present invention, not the present invention is done any pro forma restriction, every foundation technical spirit of the present invention, to any simple modification, equivalent variations and modification that above embodiment does, all still belongs in the scope of technical solution of the present invention.
