Abstract
The utility model discloses a light-weight instrument control flexible cable. A nylon rope is hinged to the center of a conductor, an insulation layer covers the outside of the conductor in an extrusion mode and an isolation layer surrounds the outside of the conductor. Single cable cores composed of knitted copper wire shielding layers are disposed on the isolation layer, and a cable core consists of a plurality of single cable cores in a screwed and hinged mode. A wrapping tape layer surrounds the outside of the cable core and an outer sheath is covers the outside of the cable core in an extrusion mode. The light-weight instrument control flexible cable has the advantages of bending resistance, good flame resistance, oil resistance, light weight and the like.
Description
Technical field:
The utility model relates to a kind of light-duty instrument control flexible cable.
Background technology:
Along with development of auto-control technology, also increasingly high to the requirement of the instrumentation control cable that is used to transmit the signals of telecommunication such as various startups, operation, demonstration, measurement.Instrumentation control cable and instrument, equipment junction need frequent dismounting, require lead to possess certain flexibility and mechanical strength; For the ease of the vertical installation of cable, require cable from important as far as possible little; The space of cable laying is narrow, requires cable can bear less bending radius; Cable cover(ing) will have not flame-retarding power and a small amount of greasy dirt of permission contact, requires cable to have fire-retardant and oil resistance.
Summary of the invention:
For overcoming the defective of prior art, the purpose of the utility model is to provide a kind of light-duty instrument control flexible cable, and it has, and anti-bending, fire resistance are good, oil resistant, performance such as in light weight.
The utility model technical solution problem adopts following technical scheme:
A kind of light-duty instrument control flexible cable; The conductor center is stranded to have nylon rope; Said conductor is extruded with insulating barrier outward, is surrounded with separator; On said separator, be provided with braiding copper wire screen and constitute cable list core, the many stranded formation cable conductors of said single core spiral, said cable core is surrounded with belting layer outward, is extruded with oversheath.
Said conductor adopts the 6th type of soft copper conductor.
The cross-linked polyethylene insulating material that said insulating barrier employing wall thickness is 0.2mm extrudes formation.
Said oversheath adopts fire-retardant butyronitrile-polyvinyl chloride composite insulating sleeve.
Compared with present technology, the beneficial effect of the utility model is embodied in:
Adopt the 6th type of copper conductor as signal transmission medium, the 5th type of copper conductor commonly used has more flexibility, belongs to ultra flexible conductor, at the conductor center nylon rope is set simultaneously, improved the mechanical strength of conductor greatly.Adopt wall thickness be the crosslinked polyethylene of 0.2mm as insulating barrier, reduce the thickness of insulation, also reduced the external diameter and the weight of whole cable simultaneously.Adopt the jacket material of soft fire-retardant butyronitrile-polyvinyl chloride composite, improve the oil resistance and the anti-flammability of cable as cable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Label among the figure: 1 nylon rope, 2 conductors, 3 insulating barriers, 4 separators, 5 screens, 6 belting layers, 7 oversheaths.
Below pass through embodiment, and combine accompanying drawing that the utility model is described further.
Embodiment:
Embodiment: combine Fig. 1, the light-duty instrument control flexible cable of present embodiment has nylon rope 1 in that conductor 2 centers are stranded, and monofilament do not have mechanical damage with the nylon rope friction, guarantees that conductor is soft, good bending property not frangible, tensile strength height.Conductor is extruded with insulating barrier 3 outward, is surrounded with separator 4, and on separator 4, be provided with braiding copper wire screen 5 and constitute cable list core, the many stranded formation cable conductors of single core spiral, cable core is surrounded with belting layer 6 outward, is extruded with oversheath 7.
In specifically being provided with, conductor 2 adopts the 6th type of soft copper conductor.Insulating barrier 3 employing wall thickness are that the cross-linked polyethylene insulating material of 0.2mm extrudes formation, and crosslinked polyethylene insulation material proportion is little, electric property is superior, and ε r is little, and ρ v is big, adopts small walled 0.2mm, guarantees to have alleviated cable weight on the basis of cable electrical performance.Oversheath 7 adopts fire-retardant butyronitrile-polyvinyl chloride composite insulating sleeve.
