Description
Technical field
The present invention relates to optical cable field, specifically, be the antitorque optical cable that a kind of mechanical strength is high.
Background technology
Along with being surging forward of telecommunications, data service especially IP business is exponentially increased situation, voice, data
It is both needed to transmission, so needing bigger network capacity and broader broadband with the multimedia such as image.How user is passed through high-band
Access way wide, high-quality is linked on high speed, jumbo backbone network, and the successful realization of information superhighway is had by this
Decisive meaning.In order to meet the needs of the optical cable some application requirements supply of electric power in transmitting procedure, and also to
Resource is laid in saving, has the most had photoelectric mixed cable.But the structure of the most common photoelectric mixed cable generally also exists
The feature of tension compressive property difference, is easily damaged being squeezed when.
Chinese Patent Application No.: 201010504893 disclose the cable of a kind of plain conductor and fiber mix, and it is two
Increasing single-mode fiber in core, three cores or multicore metallic cable, wherein plain conductor is copper of the prior art, aluminum, gold, silver conduction
Material, single-mode fiber is glass optical fiber of the prior art or plastic optical fiber, is used for transmitting optical signal and ignition of cable signal.This
The structure compressive property of sample is poor, is easily damaged when being squeezed.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, be conducive to avoiding inter deterioration, can improve anti-twisting property,
The antitorque optical cable that mechanical strength that wear resistance is strong is high.
The present invention is achieved through the following technical solutions: the antitorque optical cable that a kind of mechanical strength is high, including oversheath, is arranged on
Supporting sleeve in oversheath, the inner sheath being arranged in supporting sleeve, several ferrules being arranged in inner sheath and
Several optical fiber being arranged in ferrule, the inner side of supporting sleeve is provided with several projections, and inner sheath is by raised support, outward
It is provided with armor between sheath and supporting sleeve, in inner sheath, is provided with center reinforcement.
It is filled with lubriation material in the cavity formed between described supporting sleeve, projection and ferrule.
Described lubriation material is graphite powder or lubricating oil.
Described protruding cross section is trapezoidal.
Cable cream it is filled with between described inner sheath and ferrule.
Described ferrule layer-twisted type is wrapped in outside the reinforcement of center.
Described center reinforcement is the center reinforcement using FRP to make.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) present invention is by arranging projection, by raised support inner sheath, when oversheath, supporting sleeve are distorted, and protruding energy
Enough deflect to reduce the moment of torsion that cable interior is delivered on inner sheath, and the abrasion of inner sheath can be reduced, thus improve
Antitorque, the lateral pressure resistant ability of optical cable, and extend service life of optical cable, the machinery of optical cable can be improved by arranging armor
Intensity, and avoid optical cable because be there is mechanical damage by external force, can also carry by arranging armor and center reinforcement
The tension of high optical cable, flexural strength, the service life being conducive to extending optical cable with this, it is to avoid optical cable is made because of bending
Become to damage；
(2) present invention is conducive to reducing the abrasion of inner sheath by filling lubriation material；
(3) cross section that by the present invention in that projection is trapezoidal, it is possible to prevents from occurring during protruding torsion the situation of fracture, improves convex
The service life risen.
Accompanying drawing explanation
Fig. 1 is the structural representation of the antitorque optical cable that a kind of mechanical strength is high；
Wherein 1 oversheath, 2 supporting sleeves, 3 is protruding, 4 lubriation materials, 5 inner sheaths, 6 ferrules, 7 light
Fibre, 8 armors, 9 center reinforcements.
