Description
Luftromisolert koaksialkabel. Air space insulated coaxial cable.
Den foreliggende oppfinnelse angår en koaksialkabel med luftromisolasjon. The present invention relates to a coaxial cable with air space insulation.
Når senterlederen for en luftromisolert koaksialkabel fremstilles av en for stor When the center conductor of an airspace-insulated coaxial cable is manufactured from a too large
kobbertråd ved å trekke tråden ned til kor-rekt diameter, har det vært funnet at deler av senterlederens overflate har tendens til å krølle seg vekk eller stikke ut fra lederen når denne f. eks. vikles opp på en trommel. Dette har den uønskede effekt at ionisa-sjonspotensialet mellom den indre og den ytre leder i koaksialkabelen blir redusert. Det kan da oppstå corona-utladninger når kabelen er i bruk, og dette vil resultere i et tap av det potensial som overføres langs copper wire by pulling the wire down to the correct diameter, it has been found that parts of the center conductor's surface tend to curl away or protrude from the conductor when this e.g. wound up on a drum. This has the undesirable effect that the ionization potential between the inner and the outer conductor in the coaxial cable is reduced. Corona discharges can then occur when the cable is in use, and this will result in a loss of the potential transmitted along
koaksialkabelen til en forsterker. Videre kan det dannes støy-interferens over hele koaksialkabelens frekvensområde. the coaxial cable to an amplifier. Furthermore, noise interference can form over the entire frequency range of the coaxial cable.
Ifølge den foreliggende oppfinnelse According to the present invention
skal der på senterlederen i en luftromisolert koaksialkabel tilveiebringes et belegg med tykkelse mindre enn 0,0025 mm av et materiale som har tilstrekkelig mekanisk styrke til å binde til lederen de deler av senterlederens ledende overflatemateriale som ellers ville stikke ut fra lederens overflate. a coating with a thickness of less than 0.0025 mm must be provided on the center conductor of an air space-insulated coaxial cable of a material that has sufficient mechanical strength to bind to the conductor those parts of the center conductor's conductive surface material that would otherwise protrude from the conductor's surface.
Oppfinnelsen skal i det følgende be-skrives i detalj under henvisning til teg-ningen som viser en utførelse av oppfinnelsen i perspektiv. In the following, the invention will be described in detail with reference to the drawing which shows an embodiment of the invention in perspective.
I figuren er en senterleder 1 forsynt In the figure, a central conductor 1 is provided
med avstandsskiver 2 av polyetylen og omgitt av en ytre leder 3. Den ytre leder 3 er omgitt av en polyetylenkappe 4. Senterlederen er i dette tilfellet belagt med en polyvinyl-acetal-emulsjon som har en tyk- with spacer discs 2 made of polyethylene and surrounded by an outer conductor 3. The outer conductor 3 is surrounded by a polyethylene sheath 4. The center conductor is in this case coated with a polyvinyl-acetal emulsion which has a thick
kelse mindre enn 0,0025 mm. Avstandsskivene 2 er forsynt med spalter 7 og senter-hull 8 som har en mindre diameter enn lederen 1 slik at avstandsskivene 2 holdes på plass når de først er satt inn på lederen 1. thickness less than 0.0025 mm. The spacer discs 2 are provided with slots 7 and center holes 8 which have a smaller diameter than the conductor 1 so that the spacer discs 2 are held in place when they are first inserted on the conductor 1.
Den ytre leder 3 formes ved å folde et kobberbånd langsgående utenpå avstandsskivene 2, slik at de langsgående ender av kobberbåndet butter mot hverandre. Poly-etylenkappen 4 ekstruderes rundt den ytre leder 3. The outer conductor 3 is formed by folding a copper strip longitudinally on the outside of the spacer discs 2, so that the longitudinal ends of the copper strip butt against each other. The polyethylene sheath 4 is extruded around the outer conductor 3.
Den forandring i impedans og dempning som forårsakes av belegget 6, er funnet å være mindre enn 0,1 pst. av impedansen og dempningen for en tilsvarende kabel hvis senterleder ikke er belagt. The change in impedance and attenuation caused by the coating 6 is found to be less than 0.1 percent of the impedance and attenuation for a corresponding cable whose center conductor is not coated.
Belegget 6 av polyvinyl-acetal-emulsjon kan erstattes av et belegg av et hvilket som helst elektrisk ledende eller isolerende materiale som har tilstrekkelig mekanisk styrke til å binde deler av det ledende materiale som ellers ville stikke ut fra over-flaten av lederen. Belegget av polyvinyl-acetal kan således f. eks. erstattes av et belegg av epoksy-harpiks, en polystyrenblan-ding eller en kobberbelegning. The coating 6 of polyvinyl acetal emulsion can be replaced by a coating of any electrically conductive or insulating material which has sufficient mechanical strength to bind parts of the conductive material which would otherwise protrude from the surface of the conductor. The coating of polyvinyl acetal can thus e.g. is replaced by a coating of epoxy resin, a polystyrene mixture or a copper coating.
