Abstract
The utility model provides a leak coaxial cable follows in proper order from inside to outside and radially comprises inner conductor, insulating layer, outer conductor, constraint area and restrictive coating, the inner conductor adopts 7 bursts of stranded conductor structures, the insulating layer is from inside to outside in proper order along radially compriseing bond line, FPE layer and exodermis, the bond line is mixed with HDPE by LDPE and constitutes, the bond line closely bonds on the inner conductor surface, the FPE layer bonds in an organic whole with bond line, exodermis each other, the exodermis comprises HDPE. The utility model discloses the inner conductor adopts 7 bursts of stranded conductor structures, has improved the crooked compliance of inner conductor, the bond line bonds on the inner conductor surface, does not receive the extrusion of inner conductor to make insulating the deformation when being favorable to the bending, stablizes transfer characteristic, the FPE layer bonds in an organic whole with bond line, exodermis mutually, and non -deformable when ensureing the bending guarantees transmission performance, the inner conductor adopts 7 bursts of stranded conductor structures, has improved the crooked compliance of inner conductor,
Description
Technical field
The utility model relates to a kind of leakage coaxial cable.
Background technology
Along with developing rapidly of China's urbanization, a large amount of people in the countryside enter urban work and life, bring huge pressure to urban transportation, force public transport to intensive, rapid future development, subway is the first-selection that each big city, the world solves public transport congestion problems.Because city rail traffic route navigates within urban area more, its bend and ramp more, add the difficulty of communication overlay.And existing communication all by wireless, split corrugated conduit transmission, its radio station's transmission range is maximum at 400m, and Field strength coverage is near strong far weak, anti-interference weak, and decay is very fast; Splitting corrugated conduit installation accuracy requires high, safeguards relative difficulty, is mainly used in transmission backbone.Reveal coaxial cable and there is very high use value, also can in mountain area, hills, tunnel, mine, underground structure, market or other electromagnetic field blind area of propagating.Make people utilize in these regions wireless receiving system to carry out the instrument such as mobile phone, panel computer whenever and wherever possible and read news, wireless office, inquiry data, Entertainment etc., add unlimited enjoyment to people's life.
Summary of the invention
The technical problems to be solved in the utility model makes a kind of leakage coaxial cable, long transmission distance, and Field strength coverage is even, by force anti-interference, and decay is comparatively slow, and installation accuracy is low, easy to maintenance etc.
For this reason, the utility model takes following technical scheme:
A kind of leakage coaxial cable, be radially made up of inner wire, insulating barrier, outer conductor, restraining and restrictive coating successively from inside to outside, described inner wire adopts 7 bursts of twisted wire structures; Described insulating barrier is radially made up of adhesive layer, FPE layer and exodermis from inside to outside successively, and described adhesive layer tight bond is on inner wire surface, and described FPE layer and adhesive layer, exodermis are bonded in one mutually, and described exodermis is made up of HDPE.
The braid of described outer conductor is made up of tinned wird material, and the percentage of braiding coverage of described braid is between 30-60%.
Described restraining is PE hyaline membrane, vertical wraps on outer conductor, and described restrictive coating adopts tight half squash type structure extrusion molding to form, and the vertical bag of described restraining and sheath extrusion molding synchronously carry out.
The utility model has the advantages that: 1, inner wire adopts 7 bursts of twisted wire structures, improve the bending flexibility of inner wire; 2, adhesive layer is bonded in inner wire surface, and the extruding not by inner wire when being conducive to bending makes insulation be out of shape, stable transfer characteristic; 3, FPE layer and adhesive layer, exodermis are bonding in one, not yielding when guaranteeing bending, ensure transmission performance; 4, insulation sheath HDPE layer does not embed insulation by the winding of outer conductor, avoids attenuation characteristic to be deteriorated; 5, adhesive layer and exodermis can play waterproof and stop conductor indium, reinforced insulation crushing resistance and associativity; 6, outer conductor adopts tinned wird to strengthen antioxygenic property, improves cable life; Outer conductor adopts braiding winding arrangement to have more the feature of soft good bending property than the cable that traditional copper strips or aluminium strip shielding punching are revealed; 7, restrictive coating adopts tight half squash type structure to produce, and be conducive to sheath compact, save material cost, simpler than original pure fashion of extrusion production process, flat appearance is attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Specific embodiment
With reference to accompanying drawing 1, a kind of leakage coaxial cable, is radially made up of inner wire 1, insulating barrier, outer conductor 5, restraining 6 and restrictive coating 7 from inside to outside successively, and described inner wire adopts 7 bursts of twisted wire structures; Described insulating barrier is radially made up of adhesive layer 2, FPE layer 3 and exodermis 4 from inside to outside successively, and described adhesive layer tight bond is on inner wire surface, and described FPE layer and adhesive layer, exodermis are bonded in one mutually, and described exodermis is made up of HDPE.The braid of described outer conductor is made up of tinned wird material, and the percentage of braiding coverage of described braid is between 30-60%.Described restraining is PE hyaline membrane, vertical wraps on outer conductor, and described restrictive coating adopts tight half squash type structure extrusion molding to form, and the vertical bag of described restraining and sheath extrusion molding synchronously carry out.
Finally, it is also to be noted that what enumerate above is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have many distortion.All distortion that those skilled in the art can directly derive from content disclosed in the utility model or associate, all should think the protection range of utility model.
