Description
15 20 25 30 35 7906105-7 _ 2 _ stigningen av parternas tvinning i kabelkärnan. Den tvinning av de enskilda ledarna, som föreskrivs i harmoniseringsföreskrifter- na i en tillämplig, tysk industrinorm VDE 0281 (liksom i flera 'andra länders normer), erhålls därigenom utan att man vid fram- ställningen av parterna behöver tíllgripa någon särskild tvin- ningsprocess. Därigenom undvikes utom en förhållandevis omständ- lig tillverkningsprocess sådana förluster, som uppkommer vid tvin- ningen av fintrådiga kopparledare på grund av töjning vid drag- pàkänningen i de enskilda ledarna, vilka förluster kan uppgå till cirka 3 %. _ Förfaringssättet enligt uppfinningen kan genomföras så, att de enskilda ledare som skall bilda en kabelpart, föres från rull- ställ parallellt till en sprutpressmaskin för påförande av part- isolering. Därpå kan sådana parter, om flera sprutpressmaskiner är uppställda bredvid varandra, slås till en färdig kabel vid en direkt löpande tillverkning. 15 20 25 30 35 7906105-7 _ 2 _ the rise of the parties' twisting in the cable core. The twisting of the individual conductors, which is prescribed in the harmonization regulations in an applicable German industry standard VDE 0281 (as in the standards of several other countries), is thereby obtained without the need to resort to any special twisting process in the production of the parties. In this way, in addition to a relatively cumbersome manufacturing process, such losses are avoided, which arise in the twisting of fine-wire copper conductors due to elongation at the tensile stress in the individual conductors, which losses can amount to about 3%. The method according to the invention can be carried out in such a way that the individual conductors which are to form a cable part are guided from a rolling stand in parallel to an injection molding machine for applying part insulation. Then, if several injection molding machines are arranged next to each other, such parts can be connected to a finished cable during direct production.
Uppfinningstanken skall närmare förklaras i anslutning till ett utföringsexempel, som illustreras på bifogade ritning. Figu- ren visar schematiskt framställningen av en part (litsledare) 20. _ De enskilda ledarna 10 löper från förrådsspolar 11, styrs av brytrullar 12 och leds parallellt till en riktskiva 13. Därefter leds de, fortfarande i huvudsak parallellt, till en nippel 1H, i vilken de samlas till en i sektion i det närmaste rund kontur, och från vilken de tillföres till gjuthuvudet 16 i en strängsprut- maskin 15. Den färdiga sprutpressade parten 20 består följaktli- gen av en flertrådig litsledare med sinsemellan parallellt lig- gande enskilda ledare 10, som är omslutna av en isolering. (An- talet enskilda ledare är i de realiserade fallen förhållandevis 2 tvärsnitt.) stort, exempelvis 32 vid en part med 1,5 mm Vid det vanliga, på ritningen inte visade slagningsförlop- pet, exempelvis av tre parter 20, till en kabelkärna, kablas par- terna utan bakåtvridning. Därvid kommer de enskilda ledarna 10 att automatiskt tvinnas samman inuti varje partisolering pà så- dant sätt, att kablingen får en stigning, som är större än stig- ningen av den slagna kabeln.The inventive concept will be explained in more detail in connection with an exemplary embodiment, which is illustrated in the accompanying drawing. The figure schematically shows the representation of a part (line conductor) 20. The individual conductors 10 run from supply coils 11, are guided by breaker rollers 12 and are led parallel to a directional disc 13. Then they are led, still substantially parallel, to a nipple 1H, in which they are assembled into a section in the nearest round contour, and from which they are fed to the casting head 16 in an extruder 15. The finished injection-molded part 20 consequently consists of a multi-wire line conductor with individual conductors lying parallel to each other. 10, which are enclosed by an insulation. (The number of individual conductors in the realized cases is relatively 2 cross-sections.) Large, for example 32 in the case of a part with 1.5 mm In the usual course of beating, not shown in the drawing, for example of three parts 20, to a cable core, the parts are wired without backward twisting. Thereby, the individual conductors 10 will be automatically twisted together inside each part insulation in such a way that the cabling has a pitch which is greater than the pitch of the wound cable.
