Abstract
The utility model discloses a photoelectric composite cable, which comprises a cable core and an outer sheath wrapping the cable core, wherein the cable core is at least formed by twisting a seamless stainless steel tube provided with an optical fiber, and a metal conductor provided with an outer insulation layer. The utility model has the beneficial effects that an optical unit in the prior art is replaced with the seamless stainless steel tube to greatly reduce the diameter of a finished cable when the stronger side pressure resisting performance and bearing capacity of the optical cable are ensured. Because a filling rope having the same external diameter with a twisting unit is not needed, the photoelectric composite cable has compact structure, the size of the metal conductor can be suitably increased, and the cable is suitable for long-distance and high-power circuits.
Description
Technical field
The utility model relate to a kind of can transmitting optical signal again can transferring electric power optoelectronic composite cable.
Background technology
In a lot of occasions, often need the transmitting optical signal and the signal of telecommunication simultaneously, normally lay respectively as the optical cable of optical signal transmission with as the cable of signal of telecommunication transmission, this not only brings difficulty to construction, has also increased construction and use cost.Be meeting the market requirement, people develop a kind of optoelectronic composite cable, and the cable that this optoelectronic composite cable will transmit several signals combines, and light unit, shielded power supply line are generally arranged in cable core, and the telephone wire in addition that has etc. transmits the holding wire of the signal of telecommunication.Authorize on May 21st, 2008 bulletin, China Patent No. is that 20072004117.6 utility model patent " novel photoelectric composite rope " has just been announced a kind of like this optoelectronic composite cable.This optoelectronic composite cable comprises the cable core with central reinforce member, the same protective layers such as waterstop, oversheath that are provided with ordinary optical cable or cable in the cable core outside.In cable core, be provided with optical cable, telephone wire, shielded power supply line etc. around the cable core central reinforce member.The unit that such optoelectronic composite cable will transmit several signals combines, and has saved pipeline space greatly, has reduced cost, has made things convenient for installation, is fit to laying in internal home network wiring and the urban building building.But, because this kind optoelectronic composite cable has central reinforce member, and for the integrality of structure, generally all needing to add many gasket for packings with the plain conductor equal outer diameter, compactness, external diameter are bigger inadequately to cause the composite cable structure like this; In addition, because materials used, the cable core of the optoelectronic composite cable of this kind structure need be filled cable ointment and waterstop, can shorten the useful life of optoelectronic composite cable greatly.
Summary of the invention
In order to overcome the above-mentioned deficiency of optoelectronic composite cable of the prior art, the utility model provides the optoelectronic composite cable of a kind of compact, dry type, high-power, long-distance transmissions and long service life.
The utility model is that the technical scheme that its technical problem of solution is adopted is: a kind of optoelectronic composite cable, comprise the oversheath of cable core and the described cable core of parcel, form by the plain conductor of gapless stainless steel tube that optical fiber is installed and external insulating barrier is stranded at least at described cable core.
Further, in the above-mentioned optoelectronic composite cable: outside described gapless stainless steel tube, also applied the layer of polyethylene bed course.Be filled with fine ointment in the space in gapless stainless steel tube.
Further, in the above-mentioned optoelectronic composite cable: also comprise gasket for packing in the described cable core, described gasket for packing is with described gapless stainless steel tube and the stranded cable core that forms of plain conductor.
Further, in the above-mentioned optoelectronic composite cable: oversheath is the polyethylene oversheath, and the inboard is provided with tears rope, and the outside is provided with the sign vitta that is used to discern usefulness.
The beneficial effects of the utility model are, utilize gapless stainless steel tube to replace smooth unit of the prior art, when guaranteeing that optical cable itself has stronger lateral pressure resistant performance and weight capacity, reduce the diameter of finished product cable greatly.Since need not to adopt the gasket for packing with stranded unit equal outer diameter, therefore, the optoelectronic composite cable compact conformation of this structure, the size of plain conductor just can suitably increase, and is suitable for long distance, the use of powerful circuit.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.
Fig. 1 is the sectional view of the utility model embodiment.
Among the figure: 1, optical fiber, 2, gapless stainless steel tube, 3, polyethylene bedding, 4, plain conductor, 5, oversheath, 6, gasket for packing, 7, tear rope, 8, the sign vitta, 9, insulating barrier.
Specific embodiment
Present embodiment has been inherited the advantage of electric power optical cable, the gapless stainless steel tube 2 that applies through PE that employing comprises optical fiber 1 directly is twisted into circular cable core with other element, guarantee to make optoelectronic composite cable possess good lateral pressure resistant performance again when optical cable is prevented lightning performance, the plain conductor 4 of external insulating barrier 9 and the gasket for packing 6 and the circular cable core of gapless stainless steel tube 2 direct stranded formations of insulation, but but both optical transmission also electrical transmission simultaneously of the circular cable core that is twisted into, the optical cable outermost layer is polyethylene (PE) sheath 5 with good anti-ultraviolet radiation performance.
This optoelectronic composite cable compact conformation, the plain conductor sectional area is big, cable outer diameter is little, is suitable for high-power, remote photoelectricity one transmission.Low, the technological performance of this optoelectronic composite cable cost of investment can provide faster speed and higher reliability on data and transmission of video images.This kind optoelectronic composite cable also must promote the faster and better development of China's Telecommunication's cause growing the space that has a wide range of applications on distance, the high-power circuit.
The advantage of present embodiment is:
● optical fiber and plain conductor are compounded in the same optical cable.
● optical cable and plain conductor are once constructed, and shorten the engineering time, save construction and use.
● gapless stainless steel tube applies through PE, has good insulation performance, and optical transmission and electrical transmission signal do not disturb mutually.And need not central reinforce member, gapless stainless steel tube light unit and plain conductor are directly stranded, and the compact conformation cable outer diameter is little.
● gapless stainless steel tube has good humidity resistance.
● gapless stainless steel tube has good lateral pressure resistant and tensile property.
● the power line size is big, is suitable for long distance, high-power circuit.
● extrude that the PE oversheath extrudes colored colour band simultaneously so that the quick identification of optical cable.
● polyethylene (PE) sheath has good anti-ultraviolet radiation performance.
● need not to fill the cable cream of usefulness of blocking water in the optoelectronic composite cable cable core, the useful life of improving optoelectronic composite cable greatly.
