Abstract

The utility model discloses a marine longitudinal watertight coaxial cable, which has the advantages of big tensile strength and longitudinal water resistance. The utility model comprises a cable core; a shielding layer, a water-proof aramid fiber layer and an outer sheath are orderly arranged outside the cable core; the cable core is formed by that a skin foam skin insulating layer is coated outside two strands of hinged copper conductors. When the marine longitudinal watertight coaxial cable is used in an ocean, the marine longitudinal watertight coaxial cable can bear a certain pulling force, and the marine longitudinal watertight coaxial cable has favorable water-proof performance.

Description

Ocean direction waterproof coaxial cable
Technical field
The utility model relates to communication equipment field, more particularly, relates to a kind of ocean direction waterproof coaxial cable.
Background technology
In the wire transmission network, now physically foamed pe insulation coaxial cables that adopt more, it reaches advantages such as transmission property is stable well with environmentally safe, foam degrees height, flexibility and has substituted existing product, but it also exists waterproof, humidity resistance is poor, tensile strength is little deficiency simultaneously.The cable that uses in the ocean is cracky and intaking more, will be made longitudinally very soon by some water inlets the cable solid flooding to cause the cable inner conductor surface oxidation that influence transmission performance, cable can't normally use; The cable that uses in the ocean generally need lead the equipment that drags, and need bear certain pulling force, and general cable can not bear pulling force.Existing coaxial cable above shortcomings can't satisfy in the ocean to be used.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the ocean direction waterproof coaxial cable of big, the vertical waterproof of a kind of tensile strength is provided.
The utility model ocean direction waterproof coaxial cable, be achieved by following technical proposals, comprise cable core, described cable core is disposed with screen, water resistance aramid fiber layer, oversheath outward, and described cable core coats the skin-foam-skin insulation layer outward by at least two bursts of twisted copper conductors and constitutes.
The utility model screen is the establishment outer conductor layer.
The utility model is the following beneficial effect of tool compared with prior art:
1. the utility model water resistance aramid fiber layer has the performance of water-swellable, and water entering section position space is filled up and airtight, and water can vertically not flow, thereby reaches the purpose of waterproof;
2. the utility model adopts the nonmetallic materials aramid fiber not only to improve the tensile strength of product, and has alleviated product weight.
Description of drawings
Fig. 1 is the utility model schematic cross-section.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Cable core coats the skin-foam-skin insulation layer outward by at least two bursts of twisted copper conductors and constitutes, and as shown in Figure 1, the utility model is made of strands copper conductor 1, skin-foam-skin insulation layer 2, screen 3, water resistance aramid fiber layer 4, oversheath 5 from the inside to the outside successively.The skin-foam-skin insulation layer is the skin foam skin polyethylene layer; The water resistance aramid fiber layer forms for twining; Oversheath is for extruding polyethylene or low smoke halogen-free flame-retardant polyolefin, and screen is a soft copper silk braid.

Claims (2)

1. an ocean direction waterproof coaxial cable comprises cable core, it is characterized in that, described cable core is disposed with screen, water resistance aramid fiber layer, oversheath outward, and described cable core coats the skin-foam-skin insulation layer outward by at least two bursts of twisted copper conductors and constitutes.
2. ocean according to claim 1 direction waterproof coaxial cable is characterized in that, screen is a soft copper silk braid.
