Description
Technical field
The utility model relate to a kind of can the optoelectronic composite cable of simultaneously transmitting optical signal and electric power.
Background technology
The progressively enforcement of 4,000,000,000,000 plans of expanding domestic demand along with country, the development of the big machinery enterprise of China has welcome wide development space, and particularly material carrying machine demand obviously increases.Handling machinery is of a great variety, wherein comprises from the small-scale bridge crane for the production of line, to the large-scale bank crane (STS) of deep water harbour, and for the rail-mounted gantry crane (RMG), ship unloaders, bucket-wheel stacker reclaimer etc. of intermodal freight terminal.According to the statistics of mechanical industry federation, in first trimester, 2009, it is 30% that domestic material carrying machine and associated components quantity on order increase by a year-on-year basis, and the same period in 2008, amplification was only 0.75%.Mechanical industry federation performs the kind expression of deputy chairman Cai Wei, and the situation of 2009 is better than the situation estimated the beginning of the year.
But with the critical component of the material carrying machine of fiber unit, as moving electric power transmission need by external import with control communication cable (optoelectronic composite cable), cause the device fabrication cycle long, cost is expensive.Enterprise is in a disadvantageous position in the competition in market.Due to this type of optoelectronic composite cable service condition very severe, in use often need to drag or winding folding and unfolding, bear larger pulling force, distortion power; Simultaneously also because operational environment is complicated, expose to the sun and rain, be often subject to the pounding of ore, goods fragment and foreign material, touch, scrape, mill etc., make cable cover(ing) be easy to mechanical damage occurs and scraps.
Utility model content
The purpose of this utility model to provide a kind of optoelectronic composite cable, to solve problems of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of optoelectronic composite cable, comprise cable inner core and wrap in the cable outer layer outside cable inner core, it is characterized in that: described cable inner core comprises shielding core, optical cable and wire core, shielding core, optical cable and wire core twist together, and are filled with waterproofing rope between cable inner core and cable outer layer; Cable outer layer is followed successively by aramid fiber reinforced layer and polyurethane outer jacket from inside to outside.
In an embodiment of the present utility model, described shielding core has three, and wire core has two, one, optical cable, and three shielding cores are 120
0phase angle circle distribution, two wire core and an optical cable are separately positioned among the gap of adjacent two shielding cores.
In an embodiment of the present utility model, described shielding core is followed successively by conductor, inner semiconductor layer, insulating barrier, out semiconductor layer from inside to outside.
In an embodiment of the present utility model, the conductor single line of described shielding core and wire core is the Cu-CATH-1 line by wire drawing and annealing, the zinc-plated processing of environment-friendly type.
The utility model can tolerate stretching, the bending and torsion power of repetition; Compare original gasket for packing, waterproofing rope is lightweight, intensity good, block-water effect is also better, alleviate overall weight; Adopt aramid fiber reinforced layer that the resistance to tension of cable is improved, polyurethane outer jacket makes cable have good decay resistance, the utility model frequent mobile, to bend etc. in Machine Movement Process and should have good signal transmission performance.
The detailed description and obtaining that feature of the present utility model can consult the graphic and following better execution mode of this case is well understood to.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below in conjunction with specific embodiment.
As shown in Figure 1, a kind of optoelectronic composite cable, comprises cable inner core and wraps in the cable outer layer outside cable inner core.Cable inner core comprises shielding core 10, optical cable 1 and wire core 9, and in the present embodiment, shielding core 10 has three, and wire core 9 has two, and optical cable 1 has one, and three shielding cores 10 are in 120
0phase angle circle distribution, two wire core 9 and an optical cable 1 are separately positioned among the gap of adjacent two shielding cores, and shielding core, optical cable and wire core twist together.Shielding core 10 is followed successively by conductor, inner semiconductor layer 3, insulating barrier 4, out semiconductor layer 5 from inside to outside.The conductor single line of shielding core 10 and wire core 9 is Cu-CATH-1 line 2, Cu-CATH-1 line adopts " double end " big drawing machine of the production of German NIEHOFF company to carry out wire drawing and annealing, the zinc-plated processing of environment-friendly type, after making wire drawing and annealing, wire diameter and elongation are comparatively unified, are stablized, and have ensured the production of cable conductor single line.After Cu-CATH-1 line is stranded, carries out pressing and school circle, prevent strand wire jumper.
Waterproofing rope 6 is filled with between cable inner core and cable outer layer; Compare original gasket for packing, waterproofing rope is lightweight, intensity good, block-water effect is also better, alleviate overall weight.
Cable outer layer is followed successively by aramid fiber reinforced layer 7 and polyurethane outer jacket 8 from inside to outside.Polyurethane outer jacket 8, closely sticky glutinous between aramid fiber reinforced layer 7 and waterproofing rope 6 three.Adopt aramid fiber reinforced layer that the resistance to tension of cable is improved, polyurethane outer jacket makes cable have good decay resistance.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
