Fig. 1 is the structural representation of cross section of a preferred embodiment of the utility model optoelectronic composite cable;
The mark of each parts is following in the accompanying drawing: 1, conduction copper cash, 2, insulating barrier, 3, central reinforce member, 4, optical fiber, 5, the PBT beam tube, 6, fine cream, 7, band, 8, sheath.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection range of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the utility model embodiment comprises:
A kind of optoelectronic composite cable comprises: cable core, be fitted in the band 7 of cable core periphery and be wrapped in the restrictive coating 8 of band 7 peripheries.Wherein, band 7 adopts polyester belt or waterstop, to prevent vertical infiltration of optical cable; Restrictive coating 8 adopts polyvinyl chloride, polyethylene or low-smoke halogen-free polyolefin protective cover material to process, and it has good anti-flammability, ultraviolet ray-resistance type and low-corrosiveness.
Particularly; The cable core of the utility model comprises central reinforce member 3, transmission of electricity core and optical cable core; Said transmission of electricity core and optical cable core be distributed in central reinforce member 3 around, be filled with non-absorbent material between the gap of said cable core, fully stoped the infiltration of moisture effectively.
Said transmission of electricity core comprises conduction copper cash 1 and the insulating barrier 2 that is wrapped in conduction copper cash 1 periphery.Particularly, when cable core cross-section hour, conduction copper cash 1 adopts single copper wire; When cable core cross-section was big, conduction copper cash 1 should adopt stranded copper wire.The insulating barrier 2 of conduction copper cash 1 periphery adopts polyvinyl chloride, polyethylene or crosslinked polyethylene to process, and the thickness of insulating barrier 2 is decided by standard according to actual conditions.
Said optical cable core comprises PBT beam tube 5, is arranged on the interior a plurality of optical fiber 4 of PBT beam tube, is filled in the fine cream 6 between PBT beam tube 5 and the optical fiber 4, and wherein fine cream 6 can carry out the mechanical damping protection to optical fiber 4.
