Abstract

The utility model relates to a compound floating coaxial cable which is characterized in that an inner conductor is squeeze-packed with polyethylene insulation material, a flat silk external conductor layer is woven at the outside of the polyethylene insulation material. An inner polyethylene jacket layer is squeeze-packed outside of the flat silk external conductor layer, a flat silk external conductor layer is woven again outside of the inner polyethylene jacket layer, and an inner polyethylene jacket layer is squeeze-packed again outside of the flat silk external conductor layer. The remaining cable section of the outer conductor without weaving the second layer is wrapped and fully filled with a water-blocking strip. The outside of the whole cable core is wrapped with an aromatic polyamide reinforcer layer which is squeeze-packed with the inner polyethylene jacket that is squeeze-packed with an external foamed polyethylene sheath. The utility model has the advantages that: (1) the structure and the function of two cables can be unified two into one, the deficiencies of the prior floating coaxial cable and the prior floating cable antenna are overcome ; (2) the product not only has low density, high strength, little attenuation, and the length direction and the width direction are water tight, but also has wider range of the wavelength, two-way transmission, even outer diameter, and small tolerance.

Description

Compound floating coaxial cable

Technical field

The utility model relates to a kind of communication coaxial cable, relates in particular to a kind of compound floating coaxial cable that is used for submarine sending and receiving signal and navigation under water.

Background technology

Floating coaxial cable and buoyant cable antenna are the chief component of submarine trailing aerial, can with communication equipment and the rowland on the submarine, omega navigation receiver matches, and is used for submarine sending and receiving signal and navigation under water, it has, and density is low, intensity is high, it is little to decay, and the external diameter tolerance is little, the characteristics of the equal watertight of vertical and horizontal, but part also comes with some shortcomings, two kinds of cables must connect use, cause to connect inconvenience and connector easy break-down between the cable, cause system reliability to descend.(2) being assembled into behind the antenna can only the number of collection of letters and navigation, and can not send signal, can not transmitted in both directions and use wave-length coverage limited.

Summary of the invention

The purpose of this utility model provides a kind of compound floating coaxial cable (total length 610M), not only density is low for it, the intensity height, decay is little, external diameter is even and tolerance is little, the equal watertight of vertical and horizontal and above-mentioned two kinds of cables are integrated, use wave-length coverage wideer, broadband, transmitted in both directions can satisfy the requirement of submarine deep water towing.

The utility model is achieved like this: it comprises inner wire, polyethylene layer, the flat filament braided outer conductor, the polyethylene inner sheath, waterstop, the polyethylene foam oversheath, it is characterized in that outside inner wire, extruding polyethylene layer, polyethylene layer weaves ground floor flat copper silk outer conductor outward, flat copper silk braided outer conductor extrudes ground floor polyethylene inner sheath outward, the polyethylene inner sheath weaves second layer flat filament outer conductor (40M) outward again, second layer flat filament braided outer conductor extrudes second layer polyethylene inner sheath outward, all the other no second layer flat filament braided outer conductor cut cables (570M) wrapped filling rounding of waterstop, the outer wrapped one deck aramid fiber reinforcement of whole cable conductor (610M), the aramid fiber reinforcement extrudes the three-layer polyethylene inner sheath outward, and the three-layer polyethylene inner sheath extrudes the polyethylene foam oversheath outward.

The utility model has the advantages that: (1) has overcome the deficiency of existing floating coaxial cable and buoyant cable antenna, two kinds of constructions of cable and function are united two into one, (2) not only density is low for product, the intensity height, it is little to decay, the equal watertight of vertical and horizontal, and use wave-length coverage wideer, transmitted in both directions, external diameter is even and tolerance is little.
