Abstract
The present invention relates to technical field of electric wires and cables, particularly a kind of light harvesting fiber communication simultaneously and electric power transfer are in the optoelectronic composite cable of one. optoelectronic composite cable comprises oversheath, is provided with photoelectricity transmission unit in oversheath, and photoelectricity transmission unit comprises that photoelectricity transmission unit comprises center conductor and is molded over the optical fiber of the outside and coated center conductor of center conductor, because photoelectricity transmission unit is molded over its optical fiber the outside of center conductor, instead of as traditional optoelectronic composite cable by the optical fiber of moulding in advance together with wire stranding, therefore can thoroughly eliminate the problem that the optical fiber that causes due to stranded technique is scrapped, in addition, because optical fiber is the outside that is molded directly within center conductor, therefore can make optical fiber utilize the tensile characteristics of center conductor, avoid optical fiber to be drawn in the time of the power such as optoelectronic composite cable is pulled bad, as can be seen here, optoelectronic composite cable of the present invention has solved the problem that scrappage is high and tensile property is poor of existing optoelectronic composite cable.
Description
Technical field
The present invention relates to technical field of electric wires and cables, particularly relate to a kind of light harvesting fiber communication simultaneously and electric power transfer in the optoelectronic composite cable of one.
Background technology
At present, the fast development of intelligent grid has proposed new requirement to traditional optical cable and electric power transfer, and plastic optical fiber composite cable is as the staple product in intelligent grid construction, light harvesting fiber communication and electric power transfer are in one, have advantages of more soft, flexible, continue conveniently, cheap, meet intelligent grid informationization, automation, interactive demand, last kilometer of desirable transmission medium that be that Fiber to the home.
Existing plastic optical fiber electricity composite cable is by oversheath, the insulating power core (wire) and the fiber unit formation that are located in oversheath and twist together, wherein electric power core and fiber unit just twist together respectively after each self-forming, by in electric power core and the stranded process of optical fiber, the impaired situation of optical fiber happens occasionally, once optical fiber is damaged in stranded process, not only can cause optoelectronic composite cable to scrap, and can cause the waste of the fiber optic materials to moulding in early stage, in addition, owing to twisting together between optical fiber and wire, therefore cannot utilize the good tensile property of wire to come optical fiber to implement protection, in work progress, damage problem is also comparatively common due to optoelectronic composite cable two ends tension for optical fiber, moreover, in current optoelectronic composite cable, described oversheath adopts polyurethane jacket mostly, pe sheath or pvc sheath, and plastic optical fiber is stricter to the temperature requirement of environment for use, traditional employing polyurethane jacket, the optoelectronic composite cable of pe sheath or pvc sheath is all to adopt hot melting way and fiber unit and cable combination stranding, in this process, very easily destroy the primary characteristic of optical fiber material, damage fiber unit, make fiber-optic signal decay exceed standard value, finally cause product rejection, therefore there is the problem of the high and unstable properties of scrappage in current optoelectronic composite cable.
Summary of the invention
The object of the present invention is to provide a kind of optoelectronic composite cable, to solve the problem that scrappage is high and tensile property is poor of existing optoelectronic composite cable.
In order to address the above problem, optoelectronic composite cable of the present invention is by the following technical solutions: a kind of optoelectronic composite cable, comprise oversheath, be provided with photoelectricity transmission unit in oversheath, photoelectricity transmission unit comprises center conductor and is molded over the optical fiber of the outside and coated center conductor of center conductor.
Described center conductor is provided with fiber optic protection layer, and described fiber optic protection layer is every optical fiber and center conductor are separated.
Described fiber optic protection layer is heat-barrier coating.
The outside of described optical fiber is provided with every photosphere.
Described oversheath is knit nylon cover.
Between described oversheath and optical fiber, be provided with flame-retardant layer.
Because the photoelectricity transmission unit of optoelectronic composite cable of the present invention is molded over its optical fiber the outside of center conductor, instead of as traditional optoelectronic composite cable by the optical fiber of moulding in advance together with wire stranding, therefore can eliminate thoroughly the problem that the optical fiber that causes due to stranded technique is scrapped, in addition, because optical fiber is the outside that is molded directly within center conductor, therefore between the two, combine closely, thereby can make optical fiber utilize the tensile characteristics of center conductor, avoid optical fiber to be drawn in the time of the power such as optoelectronic composite cable is pulled bad, as can be seen here, optoelectronic composite cable of the present invention has solved the problem that scrappage is high and tensile property is poor of existing optoelectronic composite cable.
Further, the fiber optic protection layer on center conductor can be kept apart optical fiber and center conductor, thereby avoids optical fiber directly to contact with center conductor and damaged; Fiber optic protection layer is made as to heat-barrier coating and can cuts off the heat transmission between center conductor and optical fiber, avoid heat effects that center conductor produces in the time that optoelectronic composite cable the is worked transmission performance to optical fiber; Oversheath is made as to knit nylon cover and can as traditional polyurethane jacket, pe sheath or pvc sheath, uses the mode of hot melt to be combined with photoelectricity transmission unit, further avoided the impact of the performance of high temperature on optical fiber; Flame-retardant layer plays the effect of buffering ambient pressure or impact on the one hand, can avoid on the other hand optoelectronic composite cable in the accident environment such as fire, to damage inefficacy.
