Abstract
The utility model relates to a self-supporting butterfly optical-power composite cable having functions of electric conduction and optical transmission. The optical-power composite cable comprises a butterfly sheath, and characterized in that an optical communication unit is internally laid in the center the butterfly sheath, wires are internally laid on two sides of the butterfly sheath, and a hanging line is externally connected to the top of the butterfly sheath. The beneficial effects of the utility model are that: 1. requirements of optical signal transmission and power supply are both satisfied, providing convenience in use and saving laying resources; 2. the integral self-supporting structure can bear a large self-supporting stress, having good laying performances and mechanical performances and being convenient for construction and overhead laying; and 3. the cable has a simple structure, the photoelectric unit is reasonably arranged, and a V-shaped groove structure of the butterfly sheath facilitates the separation of the photoelectric unit, so that the divergence and connection are convenient and safe.
Description
Technical field
The utility model relates to a kind of self-bearing type butterfly photoelectric mixed cable with conduction and light transfer function.
Background technology
Existing optical fiber cable is mainly used in the signal transmission of telecommunications, computer and television network broadcast, mostly can not conduct electricity, and is difficult to satisfy the user demand that communication terminal device is powered simultaneously.In order to strengthen the use function of optical cable, satisfy the needs that optical cable some occasion in transmission course requires supply of electric power, also lay resource in order to save simultaneously, had at present photoelectric mixed cable.Yet existing photoelectric mixed cable mostly is the layer-twisted type structure in a cable core with light unit and plain conductor elementary layer strand, the structure of this light, the same cable core of electric unit not only affects flexibility and the economy of each cell location in the cable, and gives and transmit midway the difference of photovoltaic element and continue and make troubles.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of self-bearing type butterfly photoelectric mixed cable for the deficiency of above-mentioned prior art existence, and it is not only simple in structure, and it is little that light, electric unit influence each other, and be convenient to built on stilts laying, and uses easy construction.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is: includes the butterfly sheath, it is characterized in that the middle optical communication element that is laid with in the butterfly sheath, and difference laying wire in both sides in the butterfly sheath, the outer upside of butterfly sheath is connected with messenger wire.
Press such scheme, described butterfly sheath cross section is rectangle, offers the V-shaped groove that longitudinally extends in parallel in both sides, rectangle cross section.
Press such scheme, described optical communication element is optical fiber, fibre ribbon or tight tube fiber.
Press such scheme, described wire is single or the multiply copper conductor.
Press such scheme, described messenger wire is stranded steel wire or individual wire, and messenger wire is linked into one by surrounding layer and suspender belt and butterfly sheath.
Press such scheme, described butterfly sheath and surrounding layer and suspender belt are made by polyethylene or the good macromolecular material of other weather resistance.
The beneficial effects of the utility model are: 1, the optical signal transmission demand can be satisfied, power demands can be satisfied again, and easy to use, saved and laid resource; 2, integratedly can satisfy stronger self-supporting intensity from bearing structure, have good lay performance and mechanical performance, constructability and built on stilts laying; 3, simple in structure, photovoltaic element arranges rationally, and butterfly sheath V-shaped groove structure is convenient to the photovoltaic element separation, and difference continues convenient and safe.
Description of drawings
Fig. 1 is the transverse cross-sectional view of an embodiment of the utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Include butterfly sheath 4, described butterfly sheath cross section is rectangle, open in both sides, rectangle cross section and to be arranged with the V-shaped groove that longitudinally extends in parallel, be laid with optical communication element 3 in the middle of being in the butterfly sheath, described optical communication element is 2 single-core fibers, difference laying wire 2 in both sides in the butterfly sheath, described wire is single copper conductor, upside is connected with messenger wire 1 by suspender belt outside the butterfly sheath, described messenger wire is stranded steel wire, messenger wire outer cladding surrounding layer, surrounding layer is linked into one, surrounding layer by suspender belt and butterfly sheath, suspender belt and butterfly sheath are made by polythene material.
