Abstract

The utility model provides a miniature optical cable of armor, include the optical cable and in proper order the parcel be in interior protective sheath, sleeve pipe and the outer protection jacket in the optical cable outside, the sleeve pipe with reach between the outer protection jacket be equipped with flame retardant in the interior protective sheath. The sleeve pipe is the spiral, sheathed tube pipe body outer wall system has a polyethylene anticorrosion coating polyethylene anticorrosion coating with scribble the resin glue tie coat between the pipe body outer wall the winding of polyethylene anticorrosion coating surface has hollow tubular structure polyethylene spiral ribbed steel wires. Pipe body inner wall evenly spray has interior plastic -coated layer. The sheathed tube material is the stainless steel. The utility model discloses miniature optical cable of armor's flexible screw shell has good compliance, crushing resistance, and the aramid fiber strengthens having excellent tensile strength, satisfy the optical cable lay with the use in machinery and environmental performance's requirement. Save the pipeline resource, satisfy the real -time dilatation demand of network.

Description

Armouring micro optical cable

Technical field

The utility model relates to physical field, relates in particular to fiber optic cable communications technology, particularly a kind of armouring micro optical cable.

Background technology

Less, sooner, more excellent---this is the development trend of optical cable for many years. Easy construction, saves maintenance cost; Adapting to various adverse circumstances and artificial damage---this is the specific requirement of optical cable development. But littlely mean that protective capability is not strong, cannot adapt to some rugged environments and destruction.

Utility model content

For defect of the prior art, the purpose of this utility model is to provide the armouring micro optical cable of the less and stronger protective capability problem of a kind of good solution.

For solving the problems of the technologies described above, the utility model armouring micro optical cable, comprises optical cable and is wrapped in successively internal protective cover, sleeve pipe and the outer jointing jacket in described optical cable outside; Between described sleeve pipe and described outer jointing jacket and in described internal protective cover, be provided with flame retardant.

Described sleeve pipe is spirality; Tube body outer wall at described sleeve pipe is shaped with polyethylene anticorrosive coating, between described polyethylene anticorrosive coating and described tube body outer wall, scribbles resin glue tack coat, is wound with cannulated structure polyethylene helical rib at described polyethylene anticorrosive coating outer surface.

Evenly be coated with internal plastic coating layer at described tube body inwall.

The material of described sleeve pipe is stainless steel.

Further, be provided with a plurality of reflective tapes along the length direction of described outer jointing jacket, described reflective tape interval arranges.

Further, be provided with a plurality of phosphor strips along the length direction of described outer jointing jacket, described phosphor strip interval arranges, and described phosphor strip, comprises a silicone band, is attached with fluorescent material on silicone band.

The material of described internal protective cover and described outer jointing jacket is TPUE rubber, low smoke and zero halogen shaped material or polyethylene.

Described flame retardant is aramid fiber.

The flexible screw sleeve pipe of the utility model armouring micro optical cable has good flexibility, crushing resistance, and aramid fiber strengthens having excellent tensile property, meet optical cable lay with use procedure in the requirement of machinery and environmental performance. Save conduit resource, meet the real-time dilatation demand of network.

Brief description of the drawings

Fig. 2 is the utility model armouring micro optical cable sleeve structure schematic diagram.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model armouring micro optical cable is described in further detail.

As shown in Figure 1 and Figure 2; the utility model armouring micro optical cable; comprise optical cable 6 and be wrapped in successively internal protective cover 7, sleeve pipe 8 and the outer jointing jacket 9 in optical cable 6 outsides, meanwhile, between sleeve pipe 8 and outer jointing jacket 9 and be provided with the flame retardant 10 of aramid fiber material in internal protective cover 7. Wherein the material of internal protective cover 7 and outer jointing jacket 9 is TPUE rubber, low smoke and zero halogen shaped material or polyethylene.

Stainless steel sleeve pipe 8 is screw type, can natural torsion, have withstand voltagely, and the advantage of anti drawing strongly, can provide good barrier propterty. Wherein stainless steel sleeve pipe 8 is shaped with polyethylene anticorrosive coating 2 at tube body 4 outer walls, between polyethylene anticorrosive coating 2 and tube body 4 outer walls, scribble resin glue tack coat 3, be wound with cannulated structure polyethylene helical rib 1 in polyethylene anticorrosive coating 2 outsides, the cross sectional shape of spiral ribbed steel wire 1 is round tube, can certainly be the cannulated structure of other arbitrary shape. Be shaped with internal plastic coating layer 5 at tube body 4 inwalls, internal plastic coating layer 5 is polyurea layer, can improve the fineness of tube body 4 inwalls, has anti-corrosion function simultaneously.

Below the preferred embodiment of the utility model having been created illustrates, but the utility model is not limited to embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, and the modification that these are equal to or replacement are all included in the application's scope.
