Abstract
The utility model relates to a full-dry photoelectric composite cable comprising a loose sleeve, an optical fiber unit is laid inside the loose sleeve, and an outer sheath is wrapped outside the loose sleeve. The full-dry photoelectric composite cable is characterized in that copper clad steel wires are symmetrically arranged at both sides of the loose sleeve inside the outer sheath, and water blocking members or/and water blocking materials are filled inside and outside the loose sleeve. According to the utility model, electricity conduction and optical signal transmission can be simultaneously carried out with a single full-dry photoelectric composite cable, which provides convenience for construction and use; the full-dry photoelectric composite cable has better tensile strength and a larger suspended span; the flat cross section makes the cable body have superior bending performance and good resistance to lateral pressure so that the cable can adapt to various harsh construction conditions and complex environments; as the full-dry structure is adopted, the production cost of the composite cable can be lowered, the pollution of the composite cable to the environment can be reduced, the construction efficiency can be improved, optical fiber splicing can be more convenient and sanitary, and the construction intensity can be reduced.
Description
Technical field
The utility model relates to a kind of photoelectric mixed cable with conduction and light transfer function, is specifically related to a kind of Full-dry type photoelectric mixing cable.
Background technology
The unification of three nets of the Internet, Broadcasting Cable Network and communication network makes the transmission of information reach a new developing stage, and namely Fiber to the home and optical fiber also develops rapidly to table for FTTH.In fiber-to-the-home construction, optical cable and the cable condition that is absolutely necessary.Do not have lead unit in the existing optical cable, and also do not establish fiber unit in the cable, so in Fiber to the home actual cable laying, lay respectively optical cable and wire, this not only makes troubles to construction, has restricted efficiency of construction, and makes troubles to use.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Full-dry type photoelectric mixing cable that has simultaneously conduction and light transfer function for the deficiency that above-mentioned prior art exists, it not only is convenient to lay, efficiency of construction is high, and simple in structure, is convenient to continue and use.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is: include loose sleeve pipe, be covered with fiber unit in the pine sleeve pipe, pine sleeve pipe outer cladding oversheath, it is characterized in that the loose sleeve pipe bilateral symmetry in oversheath installs the copper covered steel wire, inside and outside loose sleeve pipe, be filled with water-blocking component or/and material water-proof material.
Press such scheme, the every side of copper covered steel wire that described symmetry is installed in loose sleeve pipe both sides is 1.
Press such scheme, described oversheath cross section is flat, and the copper covered steel wire distributes along flat direction both sides.
Press such scheme, described water-blocking component is water blocking yarn, and described material water-proof material is water-proofing powder.
Press such scheme, the fiber unit in the described loose sleeve pipe is optical fiber, and described optical fiber is 2 ~ 24 cores.
Press such scheme, be outside equipped with aramid yarn at loose sleeve pipe.
Press such scheme, described oversheath is made by halogen-free low-smoke flame retardant material, polyethylene or other macromolecular material.
The beneficial effects of the utility model are: 1, laying wire in optical cable, form the optical cable mixed structure, and can conduct electricity simultaneously and optical signal transmission, a cable puts in place, has brought convenience for construction and use; 2, adopt high-intensity copper covered steel wire as cable unit, and add aramid yarn, make to the utlity model has larger hot strength and unsettled span; 3, the utility model cross section is flat, makes the cable body have superior bending property and good lateral pressure resistant ability, can adapt to various abominable execution conditions and complex environment; 4, the utility model adopts the dry type structure, and this had both reduced the cost of manufacture of mixing cable, reduced its environmental pollution, had improved again efficiency of construction, made more convenient and the health of continuing of optical fiber, and reduces construction intensity.

Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Include loose sleeve pipe 4, be covered with fiber unit 5 in the loose sleeve pipe, described fiber unit is optical fiber, and optical fiber is 6 cores; In loose sleeve pipe, be laid with water blocking yarn 3; Pine sleeve pipe 4 outer cladding oversheaths 1, described oversheath cross section is the flattened rectangular shape, and four jiaos arrange circular arc chamfering, and oversheath is made by halogen-free low-smoke flame retardant material, polyethylene or other macromolecular material.Loose sleeve pipe bilateral symmetry in oversheath is installed copper covered steel wire 2, every side is 1, distribute along flat direction both sides, described copper covered steel wire is to be composited by the outer copper-clad of steel wire, the intensity of existing steel and toughness, the electric conductivity that has again copper has light specific gravity, advantage that cost is low, also has the characteristics that anti-fatigue performance is good, coefficient of linear expansion is little and temperature tolerance is good; Lay outside loose sleeve pipe 4 and be filled with water blocking yarn and water-proofing powder, water-proofing powder can along the filling of loose sleeve pipe longitudinal separation, consist of the dry type composite cable.Also be provided with aramid yarn 6 outside loose sleeve pipe, aramid yarn is 2, and the diagonal angle is arranged on the upper and lower sides of loose sleeve pipe, and this both can be used as the tensile reinforcement member of optical cable, can be used as out again the cable element, is convenient to the stripping of opening of cable.
