Abstract
The invention relates to the technical field of electric wire and cables, in particular to a photoelectric compound cable through which optical fiber communication and electric transmission can be integrated simultaneously. The photoelectric compound cable comprises an outer sheath, wherein a photoelectric transmission unit is arranged in the outer sheath, and comprises a central lead and an optical fiber molded outside the central lead and coated outside the central lead. The optical fiber is molded outside the central lead through the photoelectric transmission unit, and a prefabricated optical fiber is not twisted together with the lead like the conventional photoelectric compound cable, so that the problem of optical fiber discarding caused by a twisting process can be eliminated completely; moreover, the optical fiber is directly molded outside the central lead, so that the optical fiber is prevented from being damaged by force such as dragging force and the like on the photoelectric compound cable by using the tensile characteristic of the central lead; and due to the adoption of the photoelectric compound cable, the problems of high discarding rate and poor tensile property existing in the conventional photoelectric compound cable are solved.
Description
Technical field
The present invention relates to technical field of electric wires and cables, particularly relate to a kind of simultaneously light harvesting fiber communication and electric power transfer in the optoelectronic composite cable of one.
Background technology
At present, the fast development of intelligent grid has proposed Secretary to traditional optical cable and electric power transfer, and the plastic fiber composite cable is as the staple product in the intelligent grid construction, light harvesting fiber communication and electric power transfer are in one, have more soft, flexible, continue conveniently, cheap advantage, satisfy intelligent grid informationization, automation, interactive demand, the desirable transmission medium of last kilometer that is that Fiber to the home.
Existing plastic fiber is replied by cable and is closed cable and be by oversheath, be located in the oversheath and the insulating power core (wire) that twists together and fiber unit consist of, wherein electric power core and fiber unit just twist together after each self-forming respectively, in the process that electric power core and optical fiber is stranded, the impaired situation of optical fiber happens occasionally, in case optical fiber is damaged in stranded process, not only can cause optoelectronic composite cable to scrap, and can cause the waste to the fiber optic materials of moulding in early stage; In addition, owing to twist together between optical fiber and the wire, therefore can't utilize the preferably tensile property of wire to come optical fiber is implemented protection, in work progress, optical fiber is because optoelectronic composite cable two ends tension and the damage problem is also comparatively common; Moreover, in present optoelectronic composite cable, described oversheath adopts polyurethane jacket mostly, pe sheath or pvc sheath, and plastic 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 all is 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, so that the fiber-optic signal decay exceeds standard value, finally cause product rejection, therefore there is the problem of scrappage height and unstable properties in present optoelectronic composite cable.
Summary of the invention
The object of the present invention is to provide a kind of optoelectronic composite cable, with scrappage height and the poor problem of tensile property that solves 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 the photoelectricity transmission unit in the oversheath, the photoelectricity transmission unit comprises center conductor and is molded over center conductor outside and coat the optical fiber of center conductor.
Described center conductor is provided with the 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 the knit nylon cover.
Be provided with flame-retardant layer between described oversheath and the optical fiber.
Because the photoelectricity transmission unit of optoelectronic composite cable of the present invention is molded over its optical fiber the outside of center conductor, rather than as traditional optoelectronic composite cable with the optical fiber of in advance moulding and wire stranding together, therefore can eliminate thoroughly the problem that the optical fiber that causes owing to stranded technique is scrapped, in addition, because optical fiber is the outside that is molded directly within center conductor, therefore combine closely between the two, thereby can be so that optical fiber utilizes the tensile characteristics of center conductor, it is bad to avoid optical fiber to be drawn when the power such as optoelectronic composite cable is pulled, this shows that optoelectronic composite cable of the present invention has solved scrappage height and the poor problem of tensile property of existing optoelectronic composite cable.
Further, the fiber optic protection layer on the center conductor can be kept apart optical fiber and center conductor, thereby avoids optical fiber directly to contact with center conductor and damaged; The fiber optic protection layer is made as heat-barrier coating can cuts off heat transmission between center conductor and the optical fiber, avoid heat effects that center conductor produces when optoelectronic composite cable is worked to the transmission performance of optical fiber; Oversheath is made as the knit nylon cover can as traditional polyurethane jacket, pe sheath or pvc sheath, uses the mode of hot melt to be combined with the photoelectricity transmission unit, further avoided the impact of high temperature on the performance of 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 to damage inefficacy in the accident environment such as fire.
