Description

Fremgangsmåte til fremstilling av Method for the production of

en forsinkelseslinje. a delay line.

Foreliggende oppfinnelse angår en fremgangsmåte til fremstilling av en forsinkelseslinje, omfattende en isolert leder i form av en koaksialkabel. The present invention relates to a method for producing a delay line, comprising an insulated conductor in the form of a coaxial cable.

Hvor meget et elektrisk signal forsinkes av en lineær forsinkelseslinje i form av en koaksialkabel, er direkte proporsjonalt med kabelens lengde. Ved konstruksjon av en slik forsinkelseslinje benyttes en isolert leder som kappes opp i passende lengder, hvoretter en metallkappe overtrekkes isolasjonen slik at det dannes en koaksialkabel. Denne kabel oppvikles deretter i form av en spole som utgjør den ønskede forsinkelseslinje. How much an electrical signal is delayed by a linear delay line in the form of a coaxial cable is directly proportional to the length of the cable. When constructing such a delay line, an insulated conductor is used which is cut into suitable lengths, after which a metal jacket is pulled over the insulation so that a coaxial cable is formed. This cable is then wound in the form of a coil which forms the desired delay line.

Denne kjente utførelse av forsinkelseslinjer er forbundet Kfr. kl. 21a<4->68 med en rekke ulemper. Det er nødvendig å anbringe kortslutningsfor-bindelser mellom hver av spolens tørn. Hvis dette ikke utføres vil forsinkelseslinjen få en for høy induktans. Metallkappen kan ikke overtrekkes isolasjonen hvis kappens veggtykkelse er mindre enn 0,254 Ivan, og dette resulterer i en forholdsvis tung forsinkelseslinje. På grunn av at metallkappens bøyningsradius er begrenset nedad kan ikke spolen gjøres så kompakt og liten som ønskelig. De kjente for-sinkelseslinj er i form av koaksialkabel er således plasskrevende og krever dessuten en eller annen form for innkapsling, f.eks. av plast, for at de skal beholde den opprinnelige utformning. Spolene er forholdsvis dyre å fremstille, og hovedhensikten med oppfinnelsen er å komme frem til en fremgangsmåte til fremstilling av forsinkelses-linj er der de ovennevnte ulemper er opphevet, og oppfinnelsen er i første rekke kjennetegnet ved ikke-elektrisk avsetning av en tynn metallfilm på utsiden av lederens isolasjon og at lederen med den tynne metallfilm formes til en spole som deretter elektropletteres slik at det dannes et sammenhengende belegg rundt spolen. This known execution of delay lines is connected Cf. at 21a<4->68 with a number of disadvantages. It is necessary to place short-circuit connections between each of the turns of the coil. If this is not done, the delay line will have too high an inductance. The metal sheath cannot be covered with insulation if the sheath wall thickness is less than 0.254 Ivan, and this results in a relatively heavy delay line. Due to the fact that the bending radius of the metal sheath is limited downwards, the coil cannot be made as compact and small as desired. The known delay lines are in the form of coaxial cable, are thus space-consuming and also require some form of encapsulation, e.g. of plastic, so that they retain their original design. The coils are relatively expensive to produce, and the main purpose of the invention is to arrive at a method for producing delay lines in which the above-mentioned disadvantages are eliminated, and the invention is primarily characterized by the non-electrical deposition of a thin metal film on the outside of the conductor's insulation and that the conductor with the thin metal film is formed into a coil which is then electroplated so that a continuous coating is formed around the coil.

Et annet trekk ved oppfinnelsen består i at det under viklingen av spolen innlegges en metallstrimmel mellom nær hverandre liggende viklinger. Videre kan lederens isolasjon etses og sensitivi-seres slik at isolasjonens overflate blir hydrofil, hvoretter overflaten aktiveres før den ikke-elektriske metallavsetning utføres. Another feature of the invention is that during the winding of the coil, a metal strip is inserted between windings lying close to each other. Furthermore, the conductor's insulation can be etched and sensitized so that the surface of the insulation becomes hydrophilic, after which the surface is activated before the non-electric metal deposition is carried out.

Det blir også mulig å metallisere overflaten av lederens isolasjon før spolen vikles. It also becomes possible to metallize the surface of the conductor's insulation before the coil is wound.

For at oppfinnelsen lettere skal kunne forstås vil den In order for the invention to be easier to understand, it will

i det følgende bli forklart nærmere under henvisning til tegningen der: Fig. 1 er en skisse av en sirkulær forsinkelseslinje utført i henhold til oppfinnelsen, in the following be explained in more detail with reference to the drawing where: Fig. 1 is a sketch of a circular delay line made according to the invention,

På fig. 1 og 2 er det vist typiske utførelseseksempler In fig. 1 and 2, typical design examples are shown

av lineære forsinkelseslinjer i form av koaksialkabel, fremstilt i henhold til oppfinnelsen. Hver forsinkelseslinje er fremstilt ved å of linear delay lines in the form of coaxial cable, produced according to the invention. Each delay line is produced by

anvende en indre leder 10 som er forsynt med et isolasjonsbelegg 12. Metall overtrekkes isolasjonsbelegget 12 og mellom tørnenes mellomrom, use an inner conductor 10 which is provided with an insulating coating 12. Metal is coated over the insulating coating 12 and between the spaces between the mandrels,

slik at det fremkommer et kontinuerlig metallbelegg 14 rundt og mellom spolens tørn. so that a continuous metal coating 14 appears around and between the spindle of the coil.

Ved fremstilling av spolene i henhold til fig. 1 og 2 må When producing the coils according to fig. 1 and 2 must

først overflaten av isolasjonsbelegget 12 behandles før metalliseringen her kan finne sted. Isolasjonsbelegget 12 blir derfor først etset, first the surface of the insulating coating 12 is treated before the metallization here can take place. The insulating coating 12 is therefore first etched,

slik at overflaten blir tilstrekkelig ru. Etsingen kan foretas på so that the surface becomes sufficiently rough. The etching can be carried out on

mange forskjellige kjente måter, avhengig av det materiale som isolasjonsbelegget 12 består av. Por teflon benyttes således etsing ved hjelp av natrium, og for polyetylen benyttes flammeetsing. Det etsede isolasjonsbelegg 12 blir deretter utsatt for sensitivering, slik at isolasjonsbelegget blir hydrofilisk. Sensitiveringen foretas ved at isolasjonsbelegget neddykkes i en oppløsning av stanoklorid. Isolasjonsbelegget 12 blir deretter aktivisert ved neddykking i en oppløs- many different known ways, depending on the material of which the insulating coating 12 consists. Etching using sodium is thus used for Teflon, and flame etching is used for polyethylene. The etched insulating coating 12 is then subjected to sensitization, so that the insulating coating becomes hydrophilic. Sensitization is carried out by immersing the insulation coating in a solution of stannous chloride. The insulation coating 12 is then activated by immersion in a solvent

ning av palladiumklorid eller gullklorid, hvorved isolasjonsbelegget utsettes for en monomolekylær avsetning av gull eller palladium. Isolasjonsbelegget 12 kan etter en slik behandling bli metallisert. ning of palladium chloride or gold chloride, whereby the insulation coating is exposed to a monomolecular deposit of gold or palladium. The insulation coating 12 can be metallized after such a treatment.

Det således behandlede isolasjonsbelegg 12 blir metallisert ved hjelp av ikke-elektrisk plettering, hvorved et meget tynt, kontinuerlig metallbelegg, f.eks. sølv, kobber eller gull, avsettes på isolasjonsbelegget 12. Den indre leder 10 blir deretter utformet til den ønskede spoleform ved hjelp av vanlig viklingsteknikk. Spolen blir deretter elektroplettert ved å anvende kjente elektropletteringstek-nikker, slik at en passende mengde metall (fra 0,0254 til 0,127 mm) avsettes på isolasjonsbelegget 12 og i mellomrommene mellom spolens tørn, slik at det oppnås et kontinuerlig metallbelegg over hele spolen. The insulation coating 12 treated in this way is metallized by means of non-electric plating, whereby a very thin, continuous metal coating, e.g. silver, copper or gold, is deposited on the insulating coating 12. The inner conductor 10 is then formed into the desired coil shape using conventional winding techniques. The coil is then electroplated using known electroplating techniques, so that an appropriate amount of metal (from 0.0254 to 0.127 mm) is deposited on the insulating coating 12 and in the spaces between the coil's mandrels, so that a continuous metal coating is achieved over the entire coil.

Det meget tynne metallbelegget som ble avsatt før spolen The very thin metal coating that was deposited before the coil

ble viklet, forhindrer at det oppstår kontakt mellom isolasjonsbelegget på hver av tørnene under viklingen, og således muliggjør et kontinuer- was wound, prevents contact between the insulation coating on each mandrel during winding, and thus enables a continuous

lig metallbelegg over hele spolen. Det skal gjøres oppmerksom på at det i henhold til oppfinnelsen kan anvendes en alternativ fremgangs- equal metal coating over the entire coil. It should be noted that, according to the invention, an alternative process can be used

En slik alternativ fremgangsmåte fremgår av fig. 3j som Such an alternative method appears in fig. 3j as

viser en forsinkelseslinje med mange tørn og mange lag. Fig. 3 og 4 shows a delay line with many turns and many layers. Fig. 3 and 4

viser spolen i forstørret målestokk, slik at mellomrommene mellom tørnene tydeligere fremkommer. Ved denne fremgangsmåte blir først isolasjonsbelegget etset, hvoretter lederen 10 vikles til den ønskede shows the coil on an enlarged scale, so that the spaces between the mandrels appear more clearly. In this method, the insulation coating is first etched, after which the conductor 10 is wound to the desired length

spoleform. Samtidig med viklingen blir tynne metallstrimler 18 anbrakt mellom nær hverandre liggende tørn, slik at det forhindres at det opp- coil form. At the same time as the winding, thin metal strips 18 are placed between mandrels lying close to each other, so that it is prevented that

står kontakt mellom nær hverandre liggende isolasjonsbelegg 12. Som vist på fig. 3, hvor tørnene er viklet vertikalt, er det ikke nødven- there is contact between insulating coatings 12 lying close to each other. As shown in fig. 3, where the mandrels are wound vertically, it is not neces-

dig at metallstrimlene 18 fullstendig skal omgi hver tørn. Det essen-sielle er at metallstrimlene 18 omgir tørnene i hvert avvekslende vertikale lag og delvis omgir tørnene i andre vertikale lag. Det er underforstått at metallstrimlene 18 innlegges på et tilstrekkelig an- you that the metal strips 18 should completely surround each mandrel. The essential thing is that the metal strips 18 surround the mandrels in each alternating vertical layer and partially surround the mandrels in other vertical layers. It is understood that the metal strips 18 are inserted at a sufficient

tall støter til å forhindre at det ikke oppstår kontakt mellom noen isolasjonsbelegg. numbers are used to prevent contact between any insulating coatings.

Etterat lederen 10 er blitt viklet til den ønskede spole- After the conductor 10 has been wound into the desired coil

form med innlagte metallstrimler 18, blir isolasjonsbelegget 12 sensi-tivert ved å neddykke spolen.i en oppløsning av stahoklorid, hvor isolasjonsbelegget 12 blir hydrofilisk. Spolen blir deretter neddykket i en oppløsning av palladiumklorid eller gullklorid, for derved å akti-visere isolasjonsbelegget 12 og avsette et monomolekylært belegg av gull eller palladium. Etter aktiviseringen blir spolen metallisert ved hjelp av ikke-elektrisk plettering slik at isolasjonsbelegget 12 påføres et tynt, kontinuerlig metallbelegg. Et passe tykt metallbelegg (fra 0,0254 til 0,127 mm) blir deretter avsatt ved hjelp av kjent elektropletteringsteknikk rundt isolasjonsbelegget 12 og i mellom- form with inlaid metal strips 18, the insulation coating 12 is sensitized by immersing the coil in a solution of staph chloride, where the insulation coating 12 becomes hydrophilic. The coil is then immersed in a solution of palladium chloride or gold chloride, thereby activating the insulating coating 12 and depositing a monomolecular coating of gold or palladium. After the activation, the coil is metallized by means of non-electrical plating so that the insulating coating 12 is applied to a thin, continuous metal coating. A suitably thick metal coating (from 0.0254 to 0.127 mm) is then deposited using known electroplating techniques around the insulating coating 12 and in between

rommene mellom nær hverandre liggende tørn. Det avsatte metall er av samme materiale som metallstrimlene 18, og den ferdige spole får^hovedsakelig samme form som vist på fig. 4. the spaces between closely spaced thorns. The deposited metal is of the same material as the metal strips 18, and the finished coil takes essentially the same shape as shown in fig. 4.

Ved den beskrevne fremgangsmåte kan det således fremstilles By the method described, it can thus be produced

en lettere og mindre forsinkelseslinje i form av en koaksialkabel, a lighter and smaller delay line in the form of a coaxial cable,

enn hva som tidligere har vært mulig. Fremgangsmåten muliggjør dess- than has previously been possible. The procedure enables its

uten at det uten vanskelighet kan fremstilles forsinkelseslinjer med et stort antall forskjellige utformninger. Pletteringen av forsinkelses-linj en tjener ikke bare som en ytre leder for koaksialkabelen og som en kortslutning mellom tørnene, men også som et bindemiddel som gjør at spolen beholder sin opprinnelige form. Det er således i henhold til oppfinnelsen, på en billig og enkel måte frembrakt en lineær forsinkelseslinje i form av en koaksialkabel. without which delay lines with a large number of different designs can be produced without difficulty. The plating of the delay line serves not only as an outer conductor for the coaxial cable and as a short circuit between the mandrels, but also as a bonding agent that makes the coil retain its original shape. Thus, according to the invention, a linear delay line in the form of a coaxial cable has been produced in a cheap and simple way.
