Description
Svivelkobling for koaksiale høifrekvensledninger. Swivel connector for coaxial high-frequency cables.
Oppfinnelsen gjelder en svivelkobling The invention relates to a swivel coupling
med glidekontakter til å overføre høyfrek-vens-energi fra en av inner- og ytter-leder bestående stasjonær koaksialledning til en på samme måte sammensatt, men dreibar eller roterende koaksialledning. with sliding contacts to transfer high-frequency energy from a stationary coaxial line consisting of an inner and outer conductor to a similarly composed but rotatable or rotating coaxial line.
Slike koblinger kreves overalt hvor Such links are required everywhere
høyfrekvente energier må overføres fra en stasjonær del til en roterende eller dreibar del, som f. eks. ved radarapparater. Ener-gien som skal overføres, er ofte meget liten, hvorfor det må påsees at der ikke opptrer variasjoner i overgangsmotstander, og at ytre elektriske felt ikke får noen innflytelse på overføringen. Ellers ville der bli fremkalt energivariasjoner som overlagrer seg på et høyfrekvent signal og efter de-modulasjon av dette forårsaker støy over-lagret på nyttesignalet. De elektriske felts innflytelse kan unngås på enkel måte, idet svivelkoblingen avskjermes. high-frequency energies must be transferred from a stationary part to a rotating or swiveling part, such as by radar devices. The energy to be transferred is often very small, which is why it must be ensured that there are no variations in transition resistances, and that external electric fields have no influence on the transfer. Otherwise, energy variations would be induced which are superimposed on a high-frequency signal and, after de-modulation of this, cause noise superimposed on the useful signal. The influence of the electric fields can be avoided in a simple way, as the swivel coupling is shielded.
Det er kjent å utføre svivelkoblinger uten galvaniske kontakter, men isteden med kapasitiv eller induktiv kobling. Ved slike svivelkoblinger har dempningsmålets frekvensgang et utpreget resonans-sted. Derfor oppstår der på overgangsstedet re-fleksjon av alle bølger unntagen ved resonans. Slike svivelkoblinger er altså bare egnet til å overføre et ytterst smalt frek-vensbånd. Korrekturnettverk til å øke den innskrenkede båndbredde medfører imid-lertid betydelige energitap, som igjen må skaffes tilveie ved ekstra forsterkning. It is known to make swivel joints without galvanic contacts, but instead with capacitive or inductive coupling. With such swivel joints, the frequency response of the damping target has a distinct resonance point. Therefore, reflection of all waves except at resonance occurs at the transition point. Such swivel joints are therefore only suitable for transmitting an extremely narrow frequency band. Correction networks to increase the limited bandwidth, however, entail significant energy losses, which again must be provided by additional amplification.
Koaksialledninger som ble utført med Coaxial cables that were carried out with
flytende eller gassformet dielektrikum for liquid or gaseous dielectric for
å øke den maksimalt tillatelige overfø-ringsenergi, har behøvet koblinger-som er lukket gasstett. Ved en kjent svivelkobling av denne art er de to ytterledere som skal kobles, forbundet med hverandre ved sleperinger og flere børster som glir på disse, mens den galvaniske forbindelse mellom innerlederne kommer istand enten over en kule eller over en enkelt børste. Erfa-ringsmessig har slike kontakter variabel overgangsmotstand, så forholdet mellom nyttesignal og støysignal faller ugunstig ved overføring av små energimengder. Disse koblinger blir derfor utelukkende anvendt for overføring av store energier, som dem her eventuelt kan opptre ved sendere. to increase the maximum permissible transfer energy has required connections that are closed gas-tight. In a known swivel connection of this kind, the two outer conductors to be connected are connected to each other by slip rings and several brushes that slide on these, while the galvanic connection between the inner conductors is established either via a ball or via a single brush. According to experience, such contacts have variable transition resistance, so the ratio between useful signal and noise signal falls unfavorably when transferring small amounts of energy. These connections are therefore exclusively used for the transmission of large energies, which may occur here at transmitters.
De kjente ulemper som anvendelsen av gassformede eller flytende dielektrika innebærer, førte til at man i tiltagende grad har anvendt koaksialkabler hvis dielektrikum overveiende består av poly-etylen. Kjente svivelkoblinger til å for-binde slike koaksialkabler har såvel for innerlederne som for ytterlederne fjærkontakter som glir på en slepering. Imid-lertid er det temmelig vanskelig å bygge fjærkontakter hvor alle fjærene ligger an på sleperingene med samme trykk. Videre må sleperingkontakter normalt smøres. Både det ujevne kontakttrykk og smørin-gen fører til sterk støy. Dertil kommer at smøreproblemet ikke er enkelt å løse ved apparater som under drift er utsatt for store temperaturforskjeller. The known disadvantages that the use of gaseous or liquid dielectrics entails have led to the increasing use of coaxial cables whose dielectric consists predominantly of polyethylene. Known swivel connectors for connecting such coaxial cables have both for the inner conductors and for the outer conductors spring contacts that slide on a slip ring. However, it is rather difficult to build spring contacts where all the springs rest on the slip rings with the same pressure. Furthermore, slip ring contacts must normally be lubricated. Both the uneven contact pressure and lubrication lead to strong noise. In addition, the lubrication problem is not easy to solve with devices that are exposed to large temperature differences during operation.
Hensikten med den foreliggende opp-finnelse er å skaffe en svivelkobling av The purpose of the present invention is to provide a swivel coupling of
den innledningsvis beskrevne art, som mu- the initially described species, which mu-
liggjør signaloverføring med vilkårlig båndbredde ved liten støy og som ikke krever vedlikehold. enables signal transmission with arbitrary bandwidth at low noise and which does not require maintenance.
Ifølge oppfinnelsen blir dette oppnådd According to the invention, this is achieved
ved at koblingen har to koaksiale slepe- in that the coupling has two coaxial tow-
ringer, hvorav den ytre er ledende for- rings, of which the outer is conducting for-
bundet med ytterlederne og den dreibare metalliske koblingskapsel. På sleperingene hviler børster som ligger noe på skrå i forhold til sleperingens lengdeakse i plan gjennom denne akse, og hvis ene ende er lagret bevegelig i den tilhørende børste- bound with the outer conductors and the rotatable metallic coupling capsule. On the drag rings rest brushes that lie somewhat obliquely in relation to the longitudinal axis of the drag ring in a plane through this axis, and one end of which is movably stored in the associated brush
holder. Et elastisk trykkorgan griper over børste-endene i børsteholderen og presser børstene mot børsteholderen og mot slepe- holder. An elastic pressure device grips the brush ends in the brush holder and presses the brushes against the brush holder and against the towing

For å sikre tilnærmelsesvis konstante overgangsmotstander består på i og for seg kjent måte i det minste overflaten av børstene av sølvgrafitt og overflaten av sleperingene av hårdt sølv. In order to ensure approximately constant transition resistances, in a manner known per se, at least the surface of the brushes is made of silver graphite and the surface of the drag rings is made of hard silver.
