Abstract
The invention relates to a self-supporting butterfly-shape optical-electrical hybrid cable. The cable comprises a suspension wire coating layer (1), a butterfly sheath (2), a suspension wire (4), leads (5) and optical communication unit (6). The suspension wire coating layer (1) is connected with the butterfly sheath (2) through a connection portion (3). The suspension wire (4) is arranged in the suspension wire coating layer (1). The butterfly sheath (2) and the optical communication unit (6) are arranged in the butterfly sheath (2). The optical communication unit (6) is two single-core fibers. A cross section of the butterfly sheath (2) is in a rectangle shape. Two sides of the rectangle cross section are provided with V-shape grooves which are extended parallelly along a vertical direction. The leads (5) are laid on the two sides in the butterfly sheath (2) respectively. The cable of the invention has the advantages that self-supporting strength is high; a optical signal transmission demand and a power supply demand are satisfied; laying operation is simple; labor saving and time saving are achieved; good mechanical performance is possessed.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of self-bearing type butterfly photoelectric mixed cable.
Background technology
Along with being surging forward of telecommunications, data service especially IP operation is exponential increase situation, and the multimedias such as voice, data and image all need be transmitted, so need larger network capacity and wider broadband.How the user is linked on high speed, the jumbo backbone network by high bandwidth, high-quality access way, this successful realization to information superhighway has decisive meaning.But all there are a defective in existing optical cable or cable, namely can only distinguish transmitting optical signal or the signal of telecommunication.And in the time much need to carrying out the occasion of light signal and electric signal transmission simultaneously, can only access respectively separately optical cable and cable, need simultaneously to increase corresponding equipment.Therefore system complex is huge, is not easy to the miniaturization of system and integrated, and has also increased many costs.
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.But common photoelectric mixed cable mostly is the layer-twisted type structure in a cable core with light unit and plain conductor elementary layer strand at present, the structure of the same cable core of this employing 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.
Chinese patent application number: 201220363366.1 disclose a kind of photoelectricity mixing ripple cable; comprise optical communication element, communication unit and oversheath; this optical communication element comprises at least one pair of fiber cores; this communication unit comprises at least one electronic communication link; its carrying of the ripple cable of this structure and resistance to tension are poor; the cable major part is exposed in the extraneous air, and after through long-term exposing to the sun and rain, the protective effect that the outer jacket of cable plays is little.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, a kind of self-supporting intensity height is provided, can satisfies the optical signal transmission demand, can satisfy again the self-bearing type butterfly photoelectric mixed cable of power demands, lay simple to operate, time saving and energy saving and have good mechanical performance.
Purpose of the present invention is achieved through the following technical solutions: a kind of self-bearing type butterfly photoelectric mixed cable, it is characterized in that: it comprises messenger wire coating layer, butterfly sheath, messenger wire, wire and optical communication element, link to each other by connecting portion between messenger wire coating layer and the butterfly sheath, at least one messenger wire is arranged at the inside of messenger wire coating layer, optical communication element is arranged at the center of butterfly sheath, and the both sides of butterfly sheath inside are respectively arranged with wire.
Described optical communication element is optical fiber, fibre ribbon or tight tube fiber.
Described wire is single or the multiply copper conductor.
Described messenger wire is stranded steel wire or individual wire.
Described messenger wire coating layer, butterfly sheath and connecting portion are made by polyethylene.
Described butterfly sheath cross section is rectangle, and offers the V-shaped groove that longitudinally extends in parallel in both sides, rectangle cross section.
The present invention has the following advantages:
1, simple in structure, photovoltaic element arranges rationally, and butterfly sheath V-type groove structure is convenient to the photovoltaic element separation, and light, electric unit influence each other little, and difference continues convenient and safe.
2, be convenient to built on stilts laying, use easy construction.
3, the optical signal transmission demand can be satisfied, power demands can be satisfied again.
4, time saving and energy saving and have a good mechanical performance.
