Abstract
The invention discloses a five-core composite isolated flat cable, and the cable has a flat structure; a power cable core and a control cable core are installed in an abreast and straightly-pulled manner and then are extruded by an oversheath to form the flat cable; three parallel phase wire cores are installed at the center of the power cable core; a semi-circle of multiple soft springs and a semi-circle of hard springs are installed parallel outside the phase wire cores; the soft springs and the hard springs are helically wrapped by an elastic inner sheath; a sheath is extruded outside the elastic inner sheath; the control cable core comprises a plurality of control cores that are extruded by the sheath after intertwisting. The flat cable has the advantages of safety, reliability, good isolated effect and long service life.
Description
Technical field
The present invention relates to electric wire field, especially a kind of five core composite shock insulation flat cables.
Background technology
Along with the universal of computer technology and the develop rapidly of information industry, Intellectual district has become the development trend of modern architecture, by the comprehensive wiring system that is made up of composite cable etc. the communication in intelligent construction, computer and various equipment and facility, include comprehensive wiring system under certain conditions, be interconnected to form complete supporting entirety, to realize highly intelligentized requirement.
The band of prior art controls five core composite cables of cable core, and usual structure is by stranded with five circular cores being extruded with insulation for control cable core, or five segment conductor-cores stranded after stranded with control cable core.Five core power cables comprise five identical cores such as grade of five cross-sectional area of conductor, " three large two little " core that three cross-sectional area of conductor are large, two cross-sectional area of conductor are little or " four large one little " core that four cross-sectional area of conductor are large, cross-sectional area of conductor is little.For earthquake prone areas, the cable being embedded in underground is given a shock for a long time, easily breaks down, and existing cable lacks corresponding isolation measure.
Summary of the invention
The present invention is the shortcoming overcoming prior art existence, and provide a kind of safe and reliable, isolating affection is good, five core composite shock insulation flat cables of long service life.
For solving above technical problem, a kind of five core composite shock insulation flat cables of the present invention, this cable is squashed structure, is to extrude oversheath by the straight drag and drop postpone arranged side by side of power cable core and control cable core to form; The center of power cable core is provided with three phase cores arranged side by side, and at the outer laid out in parallel half-turn some slinky springs of phase core and half-turn some hard springs, slinky spring and hard spring wrapped elasticity inner sheath outward, extrudes sheath outside elasticity inner sheath; Extrude sheath after described control cable core is stranded by some control conductor to form.
Described phase core is by phase conductor and wrappedly form at the outer elasticity inner sheath of phase conductor.
Described hard spring is formed by supporting to play the heart and be extruded in support bullet heart elasticity protective case.
Described control conductor is more than 2 or 2, and it is by controlling conductor and be extruded in the insulating barrier controlled outside conductor to form.
Described phase conductor forms by some monofilament are stranded.
Described slinky spring is with the equidistant gap arrangement of hard spring or be covered with in the both sides of phase core periphery, and both quantity is identical.
Beneficial effect of the present invention is: the present invention carries out shock insulation protection by slinky spring, hard spring and oven wire mesh blanket to phase core and control conductor, effectively can improve the useful life of cable in the area that earthquake is multiple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated:
As shown in Figure 1, a kind of five core composite shock insulation flat cables of the present invention, is characterized in that: this cable is squashed structure, are to extrude oversheath 13 by the straight drag and drop postpone arranged side by side of power cable core 10 and control cable core 15 to form; The center of power cable core 10 is provided with three phase cores 1 arranged side by side, and at the outer laid out in parallel half-turn of phase core 1 some slinky springs 4 and half-turn some hard springs 7, slinky spring 4 wrapped elasticity inner sheath 3 outer with hard spring 7, extrudes sheath 5 outside elasticity inner sheath; Extrude sheath 5 after described control cable core 15 is stranded by some control conductor to form.
Described phase core is by phase conductor 2 and wrappedly form at the outer elasticity inner sheath 3 of phase conductor 2; Described hard spring 7 plays the heart 8 by support and is extruded in the support bullet heart 8 elasticity protective case 9 and forms; Described control conductor is more than 2 or 2, and it is by controlling conductor 11 and be extruded in the insulating barrier 12 controlled outside conductor 11 to form; Described phase conductor 2 forms by some monofilament 6 are stranded; Described slinky spring 4 and the equidistant gap arrangement of hard spring 7 or the both sides be covered with outside phase core, both quantity is identical.
Above-mentioned is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement and adjustment, these improve and adjustment also should be considered as protection scope of the present invention.
