In order to realize above-mentioned task, this utility model by the following technical solutions:
A kind of multipurpose composite environment-friendly cable, including core, core includes the conductor of three distributions triangular in shape, is enclosed with inner sheath, the first overcoat and oversheath outside core successively；Be provided with an optical fiber at the middle part of three conductors, outer fiber is enclosed with the first screen layer and elastic layer successively, is all connected by a line protecting clip between the conductor that the elastic layer of optical fiber is described with each；The outside of each described conductor is enclosed with secondary shielding layer and the second overcoat the most successively.
Further, between described inner sheath and the second overcoat, between line protecting clip and the second overcoat, it is provided with inserts.
Further, the trapezoidal structure of cross section of described line protecting clip, line protecting clip offers semicircle draw-in groove, the second overcoat outside described conductor is arranged in draw-in groove.
Further, described line protecting clip is internally provided with shell fragment, the tangent setting of outer wall of the elastic layer that shell fragment wraps up with outer fiber.
Further, filling chamber it is provided with between described shell fragment and elastic layer outer wall.
Further, the inside of described elastic layer is distributed multiple post.
Further, described conductor diameter is the 1/4～1/6 of oversheath diameter.
This utility model has a techniques below feature:
Cable the most of the present utility model has been internally integrated communication cable, can complete electric power transmission, communication transfer function by once-paving, save construction cost, improve cable service efficiency；
In cable the most of the present utility model, communication line uses the form of restricted laying, can meet the laying requirement of cable, again internal optical cable be served the effect of being effectively protected；
Insulating sheath the most of the present utility model uses environment-friendly materials to make, and has and is difficult to the feature such as burning, opposing external force infringement, is effectively improved the reliability of cable.
Accompanying drawing explanation
Fig. 1 is cross-section of cable structural representation of the present utility model；
In figure, label represents: 1 optical fiber, and 2 fill chamber, 3 shell fragments, 4 line protecting clips, 5 draw-in grooves, 6 conductors, 7 secondary shielding layers, 8 second overcoats, 9 inserts, 10 inner sheaths, 11 first overcoats, 12 oversheaths, 13 first screen layers, 14 elastic layers, 15 post.
Detailed description of the invention
Deferring to technique scheme, as it is shown in figure 1, a kind of multipurpose composite environment-friendly cable, including core, core includes the conductor 6 of three distributions triangular in shape, is enclosed with inner sheath the 10, first overcoat 11 and oversheath 12 outside core successively；Be provided with an optical fiber 1 at the middle part of three conductors 6, optical fiber 1 is outside is enclosed with the first screen layer 13 and elastic layer 14 successively, is all connected by a line protecting clip 4 between the conductor 6 that the elastic layer 14 of optical fiber 1 is described with each；The outside of each described conductor 6 is enclosed with secondary shielding layer 7 and the second overcoat 8 the most successively.
Fig. 1 illustrates the sectional view of environment-friendly cable of the present utility model, it can be seen that this cable has been internally integrated three conductors 6 and an optical fiber 1.Wherein three conductor 6 layings triangular in shape, are i.e. positioned at three apex of triangle, and optimum is equilateral triangle.Conductor 6 uses oxygenless copper material to make, it is preferable that the 1/4～1/6 of conductor 6 a diameter of oversheath 12 diameter.Inner sheath the 10, first overcoat 11 and oversheath 12 it is enclosed with successively outside the core of this programme, wherein inner sheath 10 uses environment-friendly type PVC material to make, first overcoat 11 uses galvanized steel strip or zinc-coated wire to be netted to be formed around laying, and oversheath 12 is adopted as cigarette halogen-free anti-flaming polyolefin protective cover material and extrudes and form.
Optical fiber 1 is positioned at the middle part of three conductors 6, and in order to not affected by conductor 6, all maintains a certain distance between optical fiber 1 and conductor 6.Optical fiber 1 outer wrap has the first screen layer 13 and elastic layer 14, the first screen layer 13 to use to be extruded formed by crosslinking semiconductive shieldin material, and elastic layer 14 uses high-elastic environment-friendly type PVC material to make.Outer wrap at each conductor 6 has secondary shielding layer 7 and the second overcoat 8, and wherein the used material of secondary shielding layer 7 and the first screen layer 13 are identical, and the second overcoat 8 uses cross-linking polyethylene materials to make.
Preferably, being provided with inserts 9 between inner sheath 10 and the second overcoat 8, between line protecting clip 4 and the second overcoat 8, inserts 9 is glass fiber rope.
Owing to easily causing fracture when optical fiber 1 rigidity bends and transmission signal is impacted, therefore this programme is provided with line protecting clip 4 structure.The trapezoidal structure of cross section of line protecting clip 4, line protecting clip 4 offers semicircle draw-in groove 5, and described the second overcoat 8 outside conductor 6 is arranged in draw-in groove 5.Line protecting clip 4 makes to keep between conductor 6 and optical fiber 1 fixing distance, prevents owing to optical fiber 1 is impacted by extruding or conductor 6 when normal use.As it is shown in figure 1, line protecting clip 4 is internally provided with shell fragment 3, the tangent setting of outer wall of the elastic layer 14 of shell fragment 3 and optical fiber 1 outer wrap.Shell fragment 3 can use sheet metal, and it is arranged in each line protecting clip 4, is centered around around optical fiber 1, can be squeezed at optical fiber 1, the external action such as bending time, make optical fiber 1 elastic displacement a certain distance, to avoid the rigidity of optical fiber 1 to bend.It is provided with filling chamber 2 between shell fragment 3 and elastic layer 14 outer wall, fills inside, chamber 2 and can fill flame-retardant elastomer, so that optical fiber 1 is played cushioning and protection.It addition, the inside of elastic layer 14 is distributed multiple post 15, post 15 uses Environmental-protecting elastic material to make, it is therefore an objective to increases elasticity and the bending resistance effect of elastic layer 14, plays optical fiber 1 and more fully protect.
