Abstract
The utility model discloses a light flexible fluoroplastic double-colored insulated wire, which comprises seven strands of conductive cores, one of the seven strands of conductive cores is in the center, the other six strands of conductive cores are evenly distributed around the central strand of conductive core, a plurality of single wires are stranded to form each strand of conductive core, and the seven strands of conductive cores are wrapped by a double-colored fluoroplastic insulating layer. The conductive cores are regularly arranged, and are round and flexible, and thereby the elliptic defect of the insulated cores, which is caused by the irregular stranding of the cores, is avoided; meanwhile, the fluoroplastic insulating layer realizes thin-walled, double-colored insulation; and the original twelve insulation colors are increased to seventy eight insulation colors. While keeping excellent electrical and mechanical properties, the product can better meet the requirements of mounting and connection of electric instruments in the field of aeronautics and astronautics and other industrial fields, and can better facilitate the overhaul of circuits.
Description
Technical field:
The utility model relates to field of cables, relates in particular to the double-colored insulated electric conductor of light-duty soft fluoroplastics.
Background technology:
In electric, the telecommunication apparatus in industrial departments such as Aero-Space, electromechanics, metallurgy, petrochemical industry and the connecting wiring of instrument and meter, the application of electric wire is generally wider.The conductor wire core of domestic common electric wire is generally all formed through the bundle strand by 19 strands of solid conductors, because the geometry of the conductor wire core that is formed by 19 bursts of solid conductor bundles strands when same sectional area is minimum, and rounding.But because filament diameter is thicker, the conductor wire core of making is harder, and often pliability can not satisfy client's installation requirement.In a lot of occasions, the requirement very high to weight, and need not be subjected to too high voltage, so reaching 0.15 ㎜, the insulation wall thickness gets final product.As the signal transmssion line on the equipment, carry out the differentiation of circuit through color in addition.Common color is 12 kinds, and the quantity of circuit is brought very big inconvenience with regard to the maintenance of giving equipment so often considerably beyond this numeral.
The utility model content:
The purpose of the utility model just provides the double-colored insulated electric conductor of light-duty soft fluoroplastics; The conductor wire core that solves domestic common electric wire is generally all formed through the bundle strand by 19 strands of solid conductors; Because the geometry of the conductor wire core that is formed by 19 strands of solid conductor bundles strand when same sectional area is minimum, and rounding.But because filament diameter is thicker, the conductor wire core of making is harder, and often pliability can not satisfy client's installation requirement, as the signal transmssion line on the equipment, carries out the differentiation of circuit through color in addition.Common color is 12 kinds, and the quantity of circuit is brought the problem of very big inconvenience with regard to the maintenance of giving equipment so often considerably beyond this numeral.
The technical scheme that the utility model adopts is:
Compared with prior art, the beneficial effect of the utility model is:
The double-colored insulated electric conductor of a kind of light-duty soft fluoroplastics comprises conductor wire core: have seven strands of conductor wire cores, have one to be positioned at the center in seven strands of conductor thread cores, all the other six strands are evenly distributed on around it, and per share conductor thread core is respectively again by 15 stranded forming of filament tow; Seven strands of conductor wire cores are wrapped with double-colored fluoroplastic insulation layer.
Said conductor wire core is silver-plated copper core or tin-coated copper core, and seven strands of conductor wire cores have 105 monofilament altogether.
Said double-colored fluoroplastic insulation layer; Be according to the size of cross-sectional area of conductor with the insulation external diameter; The special-purpose extrusion die that has dividing plate in the middle of adopting becomes fluid with the granular fluoroplastics resin high-temperature fusion of two kinds of different colours, extrudes respectively in the both sides of conductor wire core and processes.
Said insulation wall thickness is 0.10 ㎜-0.15 ㎜.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is through when designing conductor structure; Select for use the much thinner monofilament of diameter to be twisted into 7 strands, have 1 strand to be positioned at the center in 7 strands of conductors, all the other 6 strands are evenly distributed on around it; Per share conductor is respectively again by 15 stranded forming of filament tow; Thereby make conductor wire core be arranged with rule, realize core not only rounding but also soft purpose, avoid owing to the irregular stranded defective that causes insulation heart yearn ovalize of core; Simultaneously extrusion die is carried out brand-new design, make the fluoroplastic insulation layer realize the double-colored insulation of thin-walled.Through so improving, can make such electric wire wall thickness be reduced to 0.15 ㎜ by 0.25 ㎜, thus weight reduction; The conductor wire core pliability improves; The insulation color increases to 78 kinds more than by original 12 kinds.Product is when keeping having superior electric property and mechanical performance, and the installation that can better satisfy the electrical instrumentation equipment of Aero-Space and other industrial circles connects the maintenance of the circuit of being more convenient for.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is done further explain through embodiment:
The double-colored insulated electric conductor of a kind of light-duty soft fluoroplastics comprises conductor wire core: having in 1, seven strand of conductor thread core 1 of seven strands of conductor wire cores has one to be positioned at the center, and all the other six strands are evenly distributed on around it, and per share conductor thread core 1 is respectively again by 15 stranded forming of filament tow; Seven strands of conductor wire cores 1 are wrapped with double-colored fluoroplastic insulation layer 2; Wire core 1 is silver-plated copper core or tin-coated copper core, and seven strands of conductor wire cores 1 have 105 monofilament altogether, and double-colored fluoroplastic insulation layer is according to the size of cross-sectional area of conductor with the insulation external diameter; The special-purpose extrusion die that has dividing plate in the middle of adopting; The granular fluoroplastics resin high-temperature fusion of two kinds of different colours is become fluid, extrude respectively in the both sides of conductor wire core and process, the insulation wall thickness is 0.10 ㎜-0.15 ㎜.
The foregoing description is merely the preferred implementation of the utility model, and in addition, the utility model can also have other implementations.Need to prove that under the prerequisite that does not break away from the utility model design, any conspicuous improvement and modification all should fall within the protection range of the utility model.
