Abstract
The utility model relates to a kind of 5/4 cun of fire-resistant leakage radio frequency cable of coupled mode, and this cable is mainly used in the occasions such as subterranean railway, underground highway, parking lot, mining site and indoor communication, has Signal transmissions effect and antenna function.Comprise copper tube inner conductors, physically foamed pe insulation, embossing perforate outer conductor, fire-resistant isinglass belt, flame-retardant polyolefin sheathed, copper tube inner conductors is provided with physically foamed pe insulation, embossing perforate outer conductor, double-deck fire-resistant isinglass belt, flame-retardant polyolefin sheathed outward successively.Beneficial effect is: adopt double-deck fire-resistant isinglass belt wrapped, has stopped, owing to having metallic bur power when outer conductor is slotted, to cause the oversheath of stabbing and being coated on outside embossing perforate outer conductor, improves product fire resistance in public places.Adopt copper tube inner conductors, add the transmission performance of frequency of utilization and cable.The utility model can be used in large-scale mine tunnel, the region of subway tunnel equifrequent within 3Ghz.
Description
Technical field
The utility model relates to a kind of 5/4 cun of fire-resistant leakage radio frequency cable of coupled mode, and this cable is mainly used in the occasions such as subterranean railway, underground highway, parking lot, mining site and indoor communication, has Signal transmissions effect and antenna function.
Background technology
Leaky coaxial cable can be used for the region that general communication antenna is difficult to play a role, now widely used leaky cable outer conductor mostly adopts fluting corrugated copper tube form, on the corrugated copper tube outer conductor welded, by groover, outer conductor is outputed aperture, existing cable is due to the difference of groover equipment and grooving tool, sometimes outer conductor can be scratched when slotting, causing outer conductor to have metallic bur power to stab the oversheath being about to production, causing oversheath to damage.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of 5/4 cun of fire-resistant leakage radio frequency cable of coupled mode, at the outer wrapped two-layer mica tape of the outer conductor having hole, avoids causing oversheath to damage.
The utility model for achieving the above object, the technical scheme taked is: a kind of 5/4 cun of fire-resistant leakage radio frequency cable of coupled mode, it is characterized in that: comprise copper tube inner conductors, physically foamed pe insulation, embossing perforate outer conductor, fire-resistant isinglass belt, flame-retardant polyolefin sheathed, described copper tube inner conductors is provided with physically foamed pe insulation, embossing perforate outer conductor, double-deck fire-resistant isinglass belt, flame-retardant polyolefin sheathed outward successively; Described embossing perforate outer conductor is tubulose, on tubular outer conductor, interval is equidistantly provided with several cambered surface projection, each cambered surface projection is on one face provided with a hole or is respectively equipped with a hole in each cambered surface projection in two faces, hole on two faces is symmetrical, is endless groove between often pair of cambered surface projection.
The beneficial effects of the utility model are: adopt double-deck fire-resistant isinglass belt wrapped, and having stopped has metallic bur power due to during outer conductor perforate, cause the oversheath of stabbing and being coated on outside embossing perforate outer conductor, improve product fire resistance in public places.Adopt copper tube inner conductors, add the transmission performance of frequency of utilization and cable.The utility model can be used in large-scale mine tunnel, the region of subway tunnel equifrequent within 3Ghz.
Accompanying drawing explanation
Fig. 1 is the new structural representation of this practicality.
Embodiment
As shown in Fig. 1, a kind of 5/4 cun of fire-resistant leakage radio frequency cable of coupled mode, comprises copper tube inner conductors 1, physically foamed pe insulation 2, embossing perforate outer conductor 3, fire-resistant isinglass belt 4, flame-retardant polyolefin sheathed 5.
Above-mentioned embossing perforate outer conductor 3 is tubulose, on tubular outer conductor, interval is equidistantly provided with the protruding 3-1 of several cambered surface, the protruding 3-1 of each cambered surface is on one face provided with a hole 3-2 or is respectively equipped with a hole 3-2 at the protruding 3-1 of each cambered surface in two faces, hole 3-2 on two faces is symmetrical, is endless groove 3-3 between often couple of protruding 3-1 of cambered surface.
Outside copper tube inner conductors 1, extrude one deck physically foamed pe insulation 2 and form insulated wire cores; Outside insulated wire cores, by pricking line production line by shaping for outer conductor copper strips, after vertical weldering, embossing technique form outer conductor, then along outer conductor one side or symmetrical two sides, longitudinally carrying out perforate 3-2 is shaped to embossing perforate outer conductor 3 through slotted metal equipment; Wrapped double-deck fire-resistant isinglass belt 4 is once put up through Mica tape equipment outside embossing perforate outer conductor 3; One deck black flame-retardant polyolefin jacket 5 is extruded and lettering through sheath dispensing apparatus, product namely outside double-deck fire-resistant isinglass belt 4.
This cable size is: 5/4 cun.
