Description

Optical fiber composite-type flexible drum cable
Technical field
The utility model is related to a kind of optical fiber composite-type flexible drum cable, belongs to cable preparing technical field.
Background technology
Drum cable is mainly used on coil machine, Transport Machinery and conveyer, therefore it is required that cable should have it is very strong Resistance to dragging performance.Current drum cable is all to be internally provided with steel wire as enhancement layer in cable, main to include three kinds of knots Structure:
(1)Because cable is in folding and unfolding winding process, cable conductor stress is more concentrated, therefore in cable conductor core A centrally disposed steel wire, a part of stress is concentrated on steel wire;
(2)The stress of round cable most centrostigma sets a steel in cable bosom part in cable bosom part Silk, stress is concentrated on steel wire, thereby protects cable conductor;
(3)It is parallel outside the cable core of cable to extrude one or more steel wire, bearing capacity is concentrated on steel wire, reduce cable Internal stress.
Development with technology has control, signal, power transmission function drum cable, it is necessary to use, existing Have in technology will have three kinds of cable cores of function using it is arranged side by side it is stranded by the way of a stranded cable core, then extrude sheath.
Existing drum cable has the disadvantage that:
(1)Steel wire is arranged on the structure at conductor center, because steel wire is different with copper conductor material property, is received for a long time Unreel the easy steel wire in be easily broken off, the steel wire of fracture easily stabs insulation, reduces the service life of cable;
(2)A piece structure for steel wire is set in cable bosom, with stronger dragging performance, is not also allowed inside easy damaged Conductor, but steel wire is typically relatively large in diameter, and bending radius is big so that the cable radius of cable are larger;
(3)In the outer parallel structure for extruding steel wire of cable core, equally have Cable Bending Radius big, the problem of heavier-weight;
(4)In order to cable connector is easy to make, prior art applies one layer of talcum powder when cable is produced generally outside cable core Or wrapped one layer of isolation strip, due to drum cable be typically long-term retractable volume around so that easily produced between the cable core and sheath of cable Raw Relative sliding, easily causes the bulge phenomenon of the coat layer of power cable.
(5)By the directly stranded mode of signal, control, electric power core, because each core external diameter is not of uniform size, stranded rear cable Core section is not symmetrical structure, and the construction of cable is unstable, while in order to ensure that roundness needs to use substantial amounts of packing material, The outside diameter of cable, weight and production cost can so be increased.
The content of the invention
The purpose of this utility model is to solve the above problems, there is provided a kind of simple structure, optical fiber compact to design Composite-type flexible drum cable.
The utility model is adopted the following technical scheme that:A kind of optical fiber composite-type flexible drum cable, including cable core, the cable Core includes three power wire cores, three control conductors and fiber unit strengthening cores, and the fiber unit strengthening core is arranged at cable The center of core, three power wire cores and three control conductors are centered around around fiber unit strengthening core, outside the cable core Side extrude sheath layer;
The fiber unit strengthening core includes aramid yarn rope, and reinforcement packed layer, institute are extruded with the outside of the aramid yarn rope State and be uniformly laid with fiber unit around reinforcement packed layer, the outer layer of the fiber unit is extruded with optical fiber insulating barrier, described Saddle type bar is extruded with outside optical fiber insulating barrier, six grooves are provided with the saddle type bar;
The power wire core insulating layer of conductor that the power wire core is extruded by power wire core conductor and its outside is constituted, described dynamic Line of force core conductor is made by twisting jointly by copper wire by the stranded mode of 1+6+12 and in copper wire gap filling high intensity aramid yarn;
The control conductor insulating layer of conductor that the control conductor is extruded by control conductor conductor and its outside is constituted, the control Cable core conductor processed is made by twisting jointly by copper wire by the stranded mode of 1+6 and in copper wire gap filling high intensity aramid yarn;
The power wire core and control conductor interval are uniformly arranged in the saddle type bar groove of fiber unit strengthening core.
Further, the aramid yarn rope is made by twisting by some high intensity aramid yarns.
Further, 48 high intensity aramid yarns are uniformly filled with the power wire core conductor.
Further, 12 high intensity aramid yarns are uniformly filled with the control conductor conductor.
The utility model simple structure, compact to design, fiber unit is arranged on the outside of aramid yarn rope, and in fiber unit Outside extrudes saddle type bar, is not only effectively utilized the inner space of cable, and strengthen the protection to fiber unit, power line Core and control conductor are symmetrical arranged, and improve the overall stability of cable, and cable weight is light, and bending radius is small.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of fiber unit strengthening core of the present utility model.
Reference:Fiber unit strengthening core 1, aramid yarn rope 2, strengthen packed layer 3, fiber unit 4, optical fiber insulating barrier 5, Saddle type bar 6, power wire core 7, power wire core conductor 8, power wire core insulating layer of conductor 9, control conductor 10, control conductor conductor 11st, control conductor insulating layer of conductor 12, copper wire 13, high intensity aramid yarn 14, restrictive coating 15.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As Figure 1-Figure 2, a kind of optical fiber composite-type flexible drum cable, including cable core, cable core includes three power lines 7, three control conductors 10 of core and fiber unit strengthening core 1, fiber unit strengthening core 1 are arranged at the center of cable core, three Power wire core 7 and three control conductors 10 are centered around around fiber unit strengthening core 1, the outside extrude sheath layer 15 of cable core;
