Abstract
The utility model relates to the electric wire and cable technical field, especially to a photoelectric composite cable which can meanwhile integrate fiber transmission and power transmission into a whole. The photoelectric composite cable comprises an oversheath, the inner of which is provided with a photoelectric transmission unit which comprises a photoelectric transmission unit, center wires and fibers formed outside and covering the center wires. Because the photoelectric transmission unit makes the fibers form outside the centre wires, which is different from a traditional photoelectric composite cable which intertwists preformed fibers with wires, thus the problem of fiber discard caused by intertwisting technology can be thoroughly eliminated; furtherly, the fibers are directly formed outside the centre wires, thus the fibers can utilize tensile characteristics of the center wires to prevent the fibers from being damaged by pulling when the photoelectric composite cable is pulled. Accordingly, the photoelectric composite cable solves the problems of a high rejection factor and bad tensile characteristics of a present photoelectric composite cable.
Description
Technical field
The utility model relates to technical field of electric wires and cables, particularly relates 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 purpose of this utility model 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 utility model 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 utility model 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 utility model 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.

Fig. 1 is the structural representation of the embodiment 1 of optoelectronic composite cable of the present utility model;
Fig. 2 is the structural representation of the embodiment 2 of optoelectronic composite cable of the present utility model.
Embodiment
The embodiment 1 of optoelectronic composite cable of the present utility model; as shown in Figure 1; comprise the oversheath 11 that successively arranges from outside to inside; optical fiber 12; fiber optic protection layer 13 and center conductor 14; wherein center conductor 14 is used for transmission of electric signals; fiber optic protection layer 13 is heat-barrier coating; specifically can adopt rubber; plastics; the materials such as PVC; be wrapped in center conductor 14 outsides; optical fiber 12 is molded directly within the outside of center conductor 14 and wraps up center conductor 14 when moulding; specific practice be when the optical fiber moulding will with the center conductor of fiber optic protection layer from the mould of correspondence with synchronous the passing of optical fiber; optical fiber just is molded on the fiber optic protection layer and with center conductor and is closely linked, and oversheath 11 adopts the knit nylon cover.
The embodiment 2 of optoelectronic composite cable of the present utility model, as shown in Figure 2, the difference of present embodiment and embodiment 1 only is, has added flame-retardant layer 21 between oversheath and the optical fiber, flame-retardant layer 21 can adopt the materials such as asbestos, polyurethane.
In other embodiment of the present utility model; fiber optic protection layer described in the various embodiments described above can also omit; can also be in the outer setting of described optical fiber every photosphere; can be by being coated in consisting of every luminescent material of optical fiber outer surface, every the further appearance of mode light leakage phenomena of setting of photosphere every photosphere.
