Abstract
The utility model relates to a reinforcing type pavement micro-grooved cable comprising a cable core and an outer jacket, wherein the cable core comprises an optical fiber, fiber grease and a PBT (polybutylece terephthalate) central tube; and the outer jacket comprises a corrugated steel strip, a water-blocking strip, a polyethylene sheath and a steel wire reinforcing part.
Description
Technical field
The utility model relates to the flat road surface of a kind of enhancement mode optical cable, particularly pipe core microflute optical cable.
Background technology
Present domestic traditional road surface microflute optical cable is mainly circular configuration, lays on the road surface to have certain irrationality, and optical cable is stressed relatively concentrates, and serviceable life is short.
The utility model content
In order to solve above-mentioned drawback, the utility model provides a kind of enhancement mode road surface microflute optical cable, comprise cable core and overcoat, cable core is made up of optical fiber, fine cream, PBT center sleeve, overcoat comprises the wrinkle steel band, waterstop, pe sheath and steel wire reinforcement are formed, and wherein pe sheath adopts the moulding one-tenth flat structure of cover twice.Above-mentioned enhancement mode road surface microflute optical cable, also be: described flat structure has 3: 2 length to height ratio.
Steel wire reinforcement described in the above-mentioned enhancement mode road surface microflute optical cable is positioned at the bifocal of the ellipse of flat pe sheath inscribe.Steel wire reinforcement in the above-mentioned enhancement mode road surface microflute optical cable belongs to the parallel double structure of steel wire, and optical cable stretch-proof, lateral pressure resistant reach 2000N.
Description of drawings
Fig. 1: prior art structural representation.
Fig. 2: the flat microflute cable configuration of the utility model synoptic diagram.
Fig. 3: the utility model process chart.
Embodiment
As shown in Figure 2, the flat road surface of the enhancement mode pipe core microflute optical cable that the utility model provides comprises, PBT sleeve pipe 3, in establish optical fiber 1 wherein and fill fine cream 2, waterstop 5 and wrinkle steel band 6 are set in turn in the periphery of PBT sleeve pipe 3, form flat pe sheath 7 via secondary coating and coat above-mentioned division center with 3: 2 length to height ratios, wherein steel wire reinforcement 4 is arranged at the bifocal position of flat pe sheath inner ellipse, constitute the parallel double structure of steel wire thus, can provide optical cable stretch-proof, lateral pressure resistant to reach 2000N.
In the above-described embodiments, the length to height ratio of flat design optical cable can carry out adjusted size according to actual conditions.The anti-side pressure design that the parallel double steel wire adds wrinkle steel band 6 can provide anti-side pressure and the tensile strength of 2000-3500N after measured.
As shown in Figure 3, the flat microflute optical cable of enhancement mode pipe core is finished through the step of optical fiber warehouse-in-optical fiber coloring-secondary coating-sheath installation.
In actual use, carry out anastomose property according to the microflute dimensional structure and lay design.
Thus, it is more reasonable to use the utility model to make to lay design, reduces cost and more helps the reliable and stable of optical cable, prolongs optical cable serviceable life.
The utility model is not limited to the foregoing description; in design scope of the present utility model; the description of book according to the above description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection domain of the utility model claim.
