More and more, fiber-to-the-home growth requirement is more and more stronger.User requires higher and higher, customer requirement for the size of optical cable
Photoelectricity composite cable size is small to reach saving wiring space, cost-effective purpose, but while reduce cable size not
Evitable some mechanical performances for also reducing optical cable, and current also few in the market a can meet the two simultaneously
The optical cable of part.At present, for access optical cable in the market mostly using sleeve structure, not only size is bigger than normal, but also has oil in casing
Cream is filled, and factice for filling brings inconvenience to the welding of optical fiber.Therefore, the structure design of light composite cable is accessed also at present
Not reasonable perfect, the construction laying and operation for being unfavorable for photoelectricity composite cable use.
Invention content
The technical problems to be solved by the invention are to provide a kind of more rational tension intensity optoelectronic composite cable of structure,
High intensity, high tensile are realized, while reduces cable size, reduces the manufacture cost of optical cable, performance is stablized, and is applied for wiring
Optoelectronic composite cable needed for work provides great convenience.
The present invention to solve above-mentioned technical problem and the technical solution adopted is that：
A kind of tension intensity optoelectronic composite cable, the rounded multilayered structure of section bodies are described including cable core and wrapping layer
Wrapping layer include being wrapped in block water enhancement layer and oversheath outside the cable core successively；The cable core includes centrally disposed
The microbeam pipe of position and it is set to several mutually isostructural electric units that the microbeam pipe periphery is evenly distributed along the periphery；Institute
It states and several optical fiber is equipped in microbeam pipe, package insulating sheath forms after the electric unit is twisted by several copper wire.
Further, the microbeam pipe periphery is provided with 6 electric units.The outer diameter of the microbeam pipe is 0.95-
1.05mm, the outer diameter of the electric unit is about 0.72-0.74mm, and it is the tin plating of 0.127mm that 7 outer diameters are equipped in the electric unit
Copper wire.
More preferably, the outer diameter of the microbeam pipe is 1.0mm, and the outer diameter of the electric unit is about 0.73mm,
Further, it is additionally provided with non-metal braided layer in the oversheath periphery.The non-metal braided layer is
It is formed by the dark Flame-retardant PET monofilament braiding of a diameter of 0.2mm of 22 mesh.
The tension intensity optoelectronic composite cable structure novel, reasonable design of the utility model,
Twisted galvanized copper wire by using more, small size designs not in this way around being wrapped in around the microbeam pipe of center
It only ensure that the structural requirement of photoelectricity mixing, while meet the structures such as tension more superior than generally single copper wire tensile property
Performance adds after the reinforcers such as aramid fiber or organdy and is covered with one layer of pvc sheath or low-smoke non-halogen flame-retardant polyethylene
Oversheath, this stranding mode causes optical cable to have very strong mechanical performance, such as tensile property and lateral pressure resistant performance.It is meanwhile more
The design of the twisted galvanized copper wire and microbeam pipe of root small size has also taken into account reduction cable size, reduces the purpose of cost, reaches
Make light unit and the purpose of electric unit mixing.The composite rope efficiently reduces cable size, while saves cost again, realizes
The intensity of optoelectronic composite cable, high tensile energy, size is small, light-weight, performance is stablized, and is applied while being light unit and electric unit
Facility work provides great convenience, is adapted for use with the compound laying wiring scene of the photoelectricity more demanding to optical cable tensile strength
In.
The utility model provides the structural parameters selection of best microbeam pipe and electric unit for conventional use environment,
So that the optoelectronic composite cable of the utility model obtains best comprehensive performance.And can then have in outermost layer package non-metal braided layer
Effect improves the tension isostructuralism energy of optoelectronic composite cable.
