Abstract
The utility model discloses a kind of helicopter sling sonar system cable, it is characterised in that: include reinforced conductor wire core from inside to outside, screen layer, belting layer, reinforced braid and restrictive coating；Described reinforced conductor wire core be by many inner wires, strengthening core stranded after, at its outer wrapping extrusion molding PE insulating barrier；Wherein, many strengthening cores are to be uniformly filled in the stranded space of inner wire；Described belting layer is around wrapping in outside screen layer by PE band；Described reinforced braid is after many aramid fiber yarns add and are twisted one, multiply to be woven in outside belting layer；Described restrictive coating is outermost layer.The features such as this utility model has that tensile strength is big, external diameter is little, lightweight, low temperature resistant, anti-seawater corrosion, wear-resisting, easy folding and unfolding and excellent electric, mechanical and physical performance and chemical stability；Helicopter-mounted sling sonar system Sonar Signal can be advantageously applied to transmit.
Description
Technical field
This utility model belongs to signal transmission wire, specifically a kind of helicopter sling sonar system cable.
Background technology
At present, two series products are had for helicopter sling sonar cable, one class is to use tinned wird, silver-coated copper wire, nickel plated copper wire stranded, conductor wire core is done in extrusion molding PE insulation, many cores and the optical cable of transmission signal, add stranding after metal reinforcement, weave tinned wird, silver-coated copper wire, nickel plated copper wire, the multicore comprehensive cable of extrusion molding elastomer, this product has that external diameter is big, Heavy Weight, bending radius big, be difficult to the shortcomings such as folding and unfolding；Another kind of is to use tinned wird stranded, and extrusion molding PE insulate, and weaves tinned wird, weaves aramid yarn, the single core coaxial cable of extrusion molding elastomer, though this product external diameter is little, lightweight the shortcoming such as have tensile strength bad.
Summary of the invention
The purpose of this utility model is to solve above-mentioned technical problem, a kind of helicopter sling sonar system cable is provided, while ensureing there is the feature such as superior transmission performance, little, lightweight, the opposing chemical attack of external diameter, there is higher tensile strength, the performance such as wear-resisting.
Realizing the technical solution of the utility model is: a kind of helicopter sling sonar system cable, including reinforced conductor wire core from inside to outside, screen layer, belting layer, reinforced braid and restrictive coating；Described reinforced conductor wire core be by many inner wires, strengthening core stranded after, at its outer wrapping extrusion molding PE insulating barrier；Wherein, many strengthening cores are to be uniformly filled in the stranded space of inner wire；Described belting layer is around wrapping in outside screen layer by PE band；Described reinforced braid is after many aramid fiber yarns add and are twisted one, multiply to be woven in outside belting layer；Described restrictive coating is outermost layer.
Described inner wire is tinned wird.
The strengthening core carried secretly in described conductor wire core is aramid fiber 1313 or Fanglun l414.
Described screen layer is that the braiding of nickel-clad copper alloy wire forms, and described nickel-clad copper alloy wire external diameter is φ 0.1mm～φ 0.25mm.
Described reinforced braid is after multiply aramid fiber yarn adds and is twisted one, multiply braiding form, and described aramid fiber yarn is aramid fiber 1313 or Fanglun l414.
Described restrictive coating is to be formed by TPU extrusion molding.
The beneficial effects of the utility model are:
1, this utility model have that tensile strength is big, external diameter is little, lightweight, low temperature resistant, anti-seawater corrosion, the feature such as wear-resisting, easy folding and unfolding and excellent electric, mechanical and physical performance and chemical stability；
2, this utility model can be advantageously applied to helicopter-mounted sling sonar system Sonar Signal and transmits；
3, this utility model product preparation process is ripe, and moderate cost is practical.
Accompanying drawing explanation
Fig. 1 is this utility model cross-sectional TV structure schematic diagram.
In figure: 1 inner wire, 2 strengthening cores,
3 insulating barriers, 4 screen layers, 5 belting layers, 6 reinforced braids, 7 restrictive coatings.
Detailed description of the invention
As it is shown in figure 1, a kind of helicopter sling sonar system cable, including reinforced conductor wire core from inside to outside, screen layer 4, belting layer 5, reinforced braid 6 and restrictive coating 7；Described reinforced conductor wire core be by many tinned wird inner wires 1 with the strengthening core 2 of aramid fiber 1313 or Fanglun l414 stranded after, at its outer wrapping extrusion molding PE insulating barrier 3, wherein, many strengthening cores 2 are to be uniformly filled in the stranded space of inner wire 1；Described belting layer 5 is around wrapping in outside screen layer 4 by PE band；Described screen layer 4 is formed by the braiding of nickel-clad copper alloy wire, and braided wires external diameter is φ 0.1mm～φ 0.25mm.Described reinforced braid 6 is after many aramid fiber yarns add and are twisted one, multiply to be woven in outside belting layer 5；Described restrictive coating 7 is by the outermost layer of TPU extrusion molding.
This utility model is applied to the transmission of helicopter-mounted sling sonar system Sonar Signal, has that tensile strength is big, external diameter is little, lightweight, low temperature resistant, anti-seawater corrosion, the feature such as wear-resisting, easy folding and unfolding and excellent electric, mechanical and physical performance and a chemical stability.
This utility model is not limited to above-described embodiment, all can implement and have described good result described in this utility model content.
