Opfindelsen angår en kabeltætningsindretning af den i krav l‘s indledning angivne art.The invention relates to a cable sealing device of the kind specified in the preamble of claim 1.

Kabel tætningsindretningen angår tætning af især det strømfor-5 synende kabel i en tromlemotor for at hindre udslip af olie gennem kablet ud af tromlemotoren. Tromlemotoren har som bekendt yderst et cylindrisk svøb og to endedæksler, som er fastgjort til svøbet ved dettes ender. Endedæks 1 erne er ved hjælp af kuglelejer lejret på en centralt gennem svøbet forlø-jo bende hovedaksel nær dennes ender. Inden for svøbet er på hovedakselen anbragt en elektromotor, som befinder sig i et oliebad. linder tromlemotorens drift vil svøbet og endedæksler dreje rundt om den faststående hovedaksel, og olien vil slynges rundt inden i tromlemotoren. Herved vil dråber af olie 15 bl.a. sætte sig på kablets ende, der er afisoleret, dvs. uden yderkappé. Denne olie vil kunne sive ud af tromlemotoren igennem kablet, nemlig dels gennem mellemrummene mellem kablets enkelte ledninger, dels gennem mellemrummene mellem ledningerne og kablets yderkappe.The cable sealing device relates to sealing especially the power supply cable in a drum motor to prevent oil leakage through the cable out of the drum motor. As is well known, the drum motor has a cylindrical casing and two end caps which are attached to the casing at its ends. The end decks 1 are mounted by means of ball bearings on a central axis extending through the wraparoundly extending axis near the ends thereof. An electric motor located in the oil bath is mounted on the main shaft. When the drum motor is running, the scoop and end caps will rotate around the fixed main shaft and the oil will be thrown around inside the drum motor. Hereby drops of oil 15 i.a. settle on the cable end, which is insulated, ie. without outer jacket. This oil can seep out of the drum motor through the cable, namely through the gaps between the individual wires of the cable and partly through the gaps between the wires and the outer casing of the cable.

For at forhindre olieudslip gennem kablet er det kendt uden på ledningerne på det sted, der grænser op til endekanten af kablets yderkappe, at montere en kabeltætningsindretning, som udgøres af et muffeorgan i form af en krympbar plastmanchet, der 25 krymper ved køling efter at være opvarmet. Efter afkøling af plastmanchetten påføres lim ,f.eks. epoxy eller polyurethan, i den ende af plastmanchetten, hvor ledningerne rager ud, således at mellemrummene mellem ledningerne og mellemrummene mellem ledninger og plastmanchet udfyldes med lim. Den herved 30 dannede kabeltætningsindretning har imidlertid i praksis vist sig ikke at være helt tæt, idet olie fra tromlemotorens indre siver ud gennem kablet. Ny olie må derfor tilføres tromlemotoren fra tid til anden. Olien er nødvendig, da den tjener to formål, nemlig dels at smøre tromlemotorens dele, dels at køle 35 elektromotoren.To prevent oil leakage through the cable, it is known outside the wires in the location adjacent to the end edge of the outer casing of the cable to mount a cable sealing device which is constituted by a shrinkable plastic sleeve which shrinks upon cooling after being heated. After cooling the plastic sleeve, glue is applied, e.g. epoxy or polyurethane, at the end of the plastic cuff where the wires protrude so that the gaps between the wires and the gaps between the wires and the plastic cuff are filled with glue. However, the cable sealing device thus formed has, in practice, proved not to be completely dense, as oil from the drum motor's interior seeps through the cable. New oil must therefore be added to the drum motor from time to time. The oil is necessary as it serves two purposes, namely to lubricate the drum motor parts and to cool the electric motor.

Endvidere kendes fra britisk patenskrift nr. 882.170 en kabeltætningsindretning (jf. f i g. 5) til tætning af afslutningen af 2 DK 166473 B1 et telekommunikationskabel med et antal ledninger. Tætnings-indretningen består i hovedsagen af et cylindrisk kabelhyster (11), en inden i kåbe 1hysteret anbragt isoleringsdel (5) og en tætningsmasse (7) i form af en isolerende hærdelig støbemasse 5 til udfyldning af kabel hylsteret. Kablets fri ledninger er afisoleret over et stykke inden i kabelhylsteret, og støbemassen er i direkte berøring med de afisolerede stykker. Hver af telekommunikationskablets ledninger består af en metallisk leder og en isolering udenpå. I tilfælde af, at lederen udgøres af 10 et antal korer, vil mellemrummene mellem de enkelte korer muliggøre udsivning af olie, vand eller lignende væske gennem kablet.Furthermore, from British Patent Specification No. 882,170 a cable sealing device (cf. f in g. 5) for sealing the end of 2 DK 166473 B1 discloses a telecommunication cable with a number of wires. The sealing device consists essentially of a cylindrical cable sheath (11), an insulating member (5) disposed within the housing 1 and a sealing compound (7) in the form of an insulating hardenable casting material 5 for filling the cable sheath. The cable's free wires are stripped over a distance within the cable casing, and the casting material is in direct contact with the stripped pieces. Each of the telecommunications cable wires consists of a metallic conductor and an insulation on the outside. In the event that the conductor is made up of a plurality of cores, the gaps between the individual cores will allow leakage of oil, water or similar liquid through the cable.

Formålet med opfindelsen er at tilvejebringe en kabel tætnings-15 indretning, især til tromlemotorer, som på effektiv måde hindrer, at olie kan sive ud af tromlemotoren gennem kablet.The object of the invention is to provide a cable sealing device, especially for drum motors, which effectively prevents oil from seeping out of the drum motor through the cable.

Kabeltætningsindretningen er ifølge opfindelsen ejendommelig ved, at isoleringsdelen udgøres af en rørformet del med en 20 midterkanal og med radialt udadragende flige, som i tværsnit danner en stjerne, og mellem hvilke flige kablets frie ledninger er anbragt koaksialt med isoleringsdelens midterakse, og de frie ledninger over det afisolerede stykke inden i kabel-hylsteret er fortinnet. Ved en sådan udformning vil isole-25 ringsdelen sikre, at ledningerne i kabel hylsteret holdes adskilt fra hinanden under tilførsel og hærdning af støbemasse til udfyldning af kabel hylsteret, således at ledningernes afisolerede og fortinnede stykker ikke kan berøre hinanden, hvorved kortslutning hindres. Ved at de frie ledninger er af-30 isoleret og fortinnet over et stykke inden i kabelhylsteret opnås, at hulrummene mellem de enkelte metalliske korer i hver ledning er udfyldt med loddetin, således at udsivning af olie mellem korene ikke er mulig. Da de fortinnede stykker er uden isolering, vil støbemassen på en strækning svarende til det 35 enkelte fortinnede stykke være i direkte berøring med den tilhørende lednings metalliske korer, hvorved der dannes en effektiv spærring mod at olie kan sive ind under isoleringen.The cable sealing device according to the invention is characterized in that the insulating part is constituted by a tubular part having a central channel and radially projecting flaps forming a star, between which the free wires of the cable are arranged coaxially with the central axis of the insulation part and the free wires over the stripped piece inside the cable casing is tinned. In such a design, the insulation portion will ensure that the wires in the cable sheath are kept apart from each other during supply and cure of molding to fill the cable sheath so that the wires insulated and tinned pieces cannot touch each other, thereby preventing short circuits. By insulating and tinning the free wires over a distance within the cable casing, it is achieved that the voids between the individual metallic cores in each conduit are filled with solder, so that oil leakage between the cores is not possible. Since the tinned pieces are without insulation, the casting mass along a stretch corresponding to the individual tinned piece will be in direct contact with the metallic cores of the associated conduit, thereby forming an effective barrier to allow oil to seep under the insulation.

3 DK 166473 B1 som grænser op til den fortinnede strækning. Man forhindrer således, at olie kan sive ud gennem mellemrummene mellem isoleringens inderside og de metalliske korer. Der tilvejebringes således en fuldstændig tæt kabeltætning, som forhindrer olie i 5 at sive ud gennem kablet ud af tromlemotoren.3 DK 166473 B1 bordering the thinned stretch. Thus, it is prevented that oil can leak out through the gaps between the inside of the insulation and the metallic cores. Thus, a completely tight cable seal is provided which prevents oil from seeping through the cable out of the drum motor.

Kabeltætningsindretningen kan ifølge opfindelsen være således udformet, at isoleringsdelen i den i kabel hylsteret inderste ende har en med isoleringsdelen koaksial, cirkulær udsparing. 10 Denne udsparing vil danne et rum, hvori den isolerende støbemasse, når denne tilføres med en ind i bunden af isoleringsdelens midterkanal ført kanyle, vil flyde ud fra kanylen og fordele støbemassen, så der opnås en nemmere udfyldning af kabelhylsteret med støbemasse.According to the invention, the cable sealing device may be designed such that the insulating member at the inner end of the cable sleeve has a circular recess coaxial with the insulating member. This recess will form a space in which the insulating molding mass, when supplied with a cannula inserted into the bottom of the middle channel of the insulating member, will flow out of the cannula and distribute the molding mass to provide easier filling of the cable shell with molding mass.

Endvidere kan kabeltætningsindretningen ifølge opfindelsen hensigtsmæssigt være således uformet, at kabel hylsteret og isoleringsdelen er af po1yoxymethy1 en, og at den isolerende støbemasse er af polyurethan.Further, the cable sealing device according to the invention may conveniently be so shaped that the cable casing and insulating member are of polyoxymethylene and that the insulating molding material is of polyurethane.

Opfindelsen angår endvidere en fremgangsmåde af den i krav 4's indledning angivne art. Denne fremgangsmåde er ifølge opfindelsen ejendommelig ved, at den anvendte isoleringsdel udgøres af en rørformet del med en midterkanal og med radialt udragen-25 de flige, at de enkelte ledninger efter afisolation over et kort stykke fortinnes én ad gangen over det afisolerede, korte stykke, at de frie ledninger efter indføring af kabelhylsteret på kablets ende placeres koaksialt med isoleringsdelens midterakse i hver sit mellemrum mellem hosliggende flige på iso-30 leringsdelen, at isoleringsdelen derpå føres ind i kabelhyl steret i lille afstand fra enden af kablets yderkappe, og at kabelhylsterets udfyldning med tætningsmasse derefter foretages med en kanyle, som først føres ind i bunden af isoleringsdelens midterkanal og derefter trækkes langsomt ud under 35 afgivelse af støbemasse. Herved opnås en enkel måde at fremstille en kabeltætningsindretning på. Ved at støbemassen med en kanyle først føres ind i bunden af isoleringsdelens midter- 4 DK 166473 B1 kanal og derefter trækkes langsomt ud under afgivelse af støbemasse undgås dannelse af luftlommer i kabel hylsteret.The invention further relates to a method of the kind specified in the preamble of claim 4. According to the invention, this method is characterized in that the insulating part used is constituted by a tubular part with a central channel and with radially extending tabs, that the individual wires are thinned one short at a time over the stripped short section after stripping. the free wires, after insertion of the cable sheath on the end of the cable, are placed coaxially with the center axis of the insulating part in each space between adjacent tabs on the insulating part, that the insulating part is then inserted into the cable sheath at a small distance from the end of the outer sheath of the cable and with sealant is then made with a cannula which is first inserted into the bottom of the middle channel of the insulating member and then slowly withdrawn during release of casting material. This provides a simple way of making a cable sealing device. By first inserting the molding mass with a cannula into the bottom of the middle channel of the insulating part and then slowly withdrawing during the release of molding mass, the formation of air pockets in the cable casing is avoided.

Opfindelsen forklares nærmere nedenfor under henvisning til 5 tegningen, hvor fig. 1 viser et længdesnit efter linien I-I i fig. 2 gennem en udførelsesform for en kabel tætn ingsindretning ifølge opfindelsen monteret på enden af et kabel, 10 fig. 2 et tværsnit gennem kabel tætn ingsindretningen efter linien II—II i fig. 1, fig. 3 et snit efter linien 111 — 111 i fig. 1, 15 fig. 4 et delvis længdesnit gennem kabel tætn ingsindretni ngens isoleringsdel efter linien IV-IV i fig. 5 og fig. 5 isoleringsdelen i fig. 4 set fra venstre ende i pilens 20 V's retning.The invention is explained in more detail below with reference to the drawing, in which fig. 1 shows a longitudinal section along line I-I in FIG. 2 through an embodiment of a cable sealing device according to the invention mounted on the end of a cable; FIG. 2 is a cross-section through the cable sealing device along line II-II in FIG. 1, FIG. 3 is a section along the line 111 - 111 of FIG. 1, FIG. 4 is a partial longitudinal section through the insulating portion of the cable sealing device along line IV-IV of FIG. 5 and FIG. 5 shows the insulating part of FIG. 4 from the left end in the direction of the arrow 20 V.

Den i fig. 1, 2 og 3 viste kabeltætningsindretning 1 er beregnet til tætning af afslutningen af et elektrisk kabel 2. Som det fremgår af fig. 1 og 3 er kablet 2 opbygget af to eller 25 flere, i det viste eksempel seks, elektriske ledninger 3, som er lagt omkring et indlæg 4, der er af plastmateriale eller andet materiale. Ledningerne 3 er udvendigt indesluttet i en yderkappe 5. De enkelte ledninger 3 består inderst af snoede, metalliske korer 6, f.eks. kobbertråde, og uden på disse en 30 isolering 7.The FIG. 1, 2 and 3, the cable sealing device 1 is intended to seal the termination of an electrical cable 2. As can be seen from FIG. 1 and 3, the cable 2 is made up of two or 25 more, in the example shown six, electrical wires 3, which are laid around an insert 4 which is of plastic material or other material. The wires 3 are externally enclosed in an outer sheath 5. The individual wires 3 are innermost of twisted metallic cores 6, e.g. copper wires, and outside of these a 30 insulation 7.

Kabel tætningsindretningen 1 er som nævnt beregnet til tætning af afslutningen af kablet 2, dvs. beregnet til tætning af området mellem dels ledningerne 3, dels mellem ledningerne 3 og 35 kablets yderkappe 5 på et sted, hvor ledningerne 3 rager ud fra yderkappen 5.The cable sealing device 1 is, as mentioned, intended for sealing the end of the cable 2, ie. intended for sealing the area between partly the wires 3 and partly between the wires 3 and 35 of the outer sheath 5 of the cable at a location where the wires 3 protrude from the outer sheath 5.

Som vist i fig. 1 og 2 består kabeltætningsindretningen 1 af et muffeorgan i form af et i hovedsagen cylindrisk kabelhylster 8 med en ombøjet kant 9 i den ene ende, en isoleringsdel 10, som er anbragt inden i kabelhylsteret 8 i kåbe 1 tætn ings-5 indretningens brugsstilling, og en tætningsmasse, som udgøres af en isolerende, hærdelig støbemasse 11 og er beregnet til udfyldning af kabel hylsteret 8. Den af den ombøjede kant 9 (fig. 1) dannede cirkulære åbning har en sådan diameter i forhold til kablet 2's ydre diameter, at der er en let løbepas-10 . ning mellem kablet 2 og kanten 9.As shown in FIG. 1 and 2, the cable sealing device 1 consists of a sleeve means in the form of a substantially cylindrical cable sheath 8 with a bent edge 9 at one end, an insulating part 10 disposed within the cable sheath 8 in the housing 1 of the sealing device, and a sealing compound which is constituted by an insulating, curable casting 11 and is intended to fill the cable casing 8. The circular opening formed by the curved edge 9 (Fig. 1) has such a diameter with respect to the outer diameter of the cable 2 that is an easy running pass-10. between the cable 2 and the edge 9.

Som det endvidere fremgår af fig. 1 og 2 har isoleringsdelen 10 en ydre diameter, som er mindre end kabel hylsterets 8 indvendige diameter. Af fig. 4 og 5, hvor isoleringsdelen 10 er 15 vist for sig selv, fremgår, at isoleringsdelen 10 udgøres af en rørformet del 12 med en midterkanal 14 med radialt udadra-gende flige 13, som i tværsnit danner en stjerne, og mellem hvilke flige 13 (fig. 2) kablets frie ledninger 3 er anbragt koaksialt med isoleringsdelens 10 midterakse.Furthermore, as can be seen from FIG. 1 and 2, the insulating member 10 has an outer diameter smaller than the inside diameter of the cable sheath 8. In FIG. 4 and 5, where the insulating part 10 is shown for itself, it can be seen that the insulating part 10 consists of a tubular part 12 with a central channel 14 with radially outwardly extending tabs 13 forming a star and between which tabs 13 ( Fig. 2) The free wires 3 of the cable are arranged coaxially with the central axis of the insulating part 10.

Som vist i fig. 1 er de frie ledninger 3 over et stykke a inden i kabelhylsteret 8 afisoleret og fortinnet.As shown in FIG. 1, the free wires 3 over a piece a within the cable housing 8 are stripped and tinned.

Ved den ovenfor beskrevne konstruktion vil isoleringsdelen 10 25 sikre, at ledningerne 3 i kabelhylsteret 8 holdes adskilt fra hinanden under tilførsel og hærdning af støbemasse 11 til udfyldning af kabel hylsteret 8, således at ledningernes 3 afisolerede og fortinnede stykker a ikke kan berøre hinanden, hvorved kortslutning hindres. Ved at de frie ledninger 3 er afiso-30 leret og fortinnet over et stykke a inden i kabel hylsteret 8 opnås, at hulrummene mellem de enkelte metalliske korer 6 i hver ledning 3 er udfyldt med loddet in, således at udsivning af olie mellem korene 6 ikke er mulig. Da de fortinnede stykker a (fig. 1) er uden isolering, vil støbemassen på en stræk-35 ning svarende til det enkelte fortinnede stykke a være i direkte berøring med den tilhørende lednings 3 metaliske korer 6, hvorved der dannes en effektiv spærring mod, at olie kan 6 DK 166473 B1 sive ind under isoleringen 7, som grænser op til den fortinnede strækning. Man forhindrer således, at olie kan sive ud gennem mellemrummene mellem isoleringens 7 inderside og de metalliske korer 6. Der tilvejebringes således en fuldstændig 5 tæt kabeltætning, som forhindrer olie i at sive ud gennem kablet 2 og dermed ud af den motor, f.eks. tromlemotor, hvori kablet er anvendt.In the construction described above, the insulating part 10 25 will ensure that the wires 3 of the cable sheath 8 are kept apart from each other during supply and curing of mold 11 to fill the cable sheath 8 so that the insulated and tinned pieces of the wires 3 cannot touch each other, whereby short circuit is prevented. By freeing the free conduits 3 and de-thinning over a piece a within the cable casing 8, the voids between the individual metallic cores 6 in each conduit 3 are filled with soldered in, so that oil leakage between the cores 6 is not possible. Since the tinned pieces a (Fig. 1) are without insulation, the casting mass on a stretch corresponding to the individual tinned piece a will be in direct contact with the metallic cores 6 of the associated conduit 3, thereby forming an effective barrier to, that oil may seep under the insulation 7 which is adjacent to the tinned stretch. Thus, it is prevented that oil can leak out through the gaps between the inside of the insulation 7 and the metallic cores 6. Thus, a complete 5 tight cable seal is provided which prevents oil from seeping out through the cable 2 and thus out of the motor, e.g. . drum motor in which the cable is used.

Som det fremgår af fig. 1 og 4, kan isoleringsdelen 10 i den i 10 kabel hylsteret 8 inderste ende have en med isoleringsdelen 10 koaksial, cirkulær udsparing 15. Denne udsparing 15 vil danne et rum, hvori den isolerende støbemasse 11, når denne tilføres med én ind i bunden af isoleringsdelens midter kanal 14 ført kanyle, vil flyde ud fra kanylen og fordele støbemassen 11, 15 således at der opnås en nemmere fyldning af kabel hylsteret 8 med støbemasse 11.As shown in FIG. 1 and 4, the insulating member 10 at the innermost end of the casing 8 in the cable 10 may have a coaxial circular recess 15 with the insulating member 10. This recess 15 will form a space in which the insulating molding mass 11, when supplied with one into the bottom of the the middle 14 of the insulating member, passed through the cannula, will flow out of the cannula and distribute the molding mass 11, 15 so that easier filling of the cable casing 8 with molding mass 11 is obtained.

Kabel hylsteret 8 og isoleringsdelen 10 kan hensigtsmæssigt være af polyoxymethylen, og den isolerende støbemasse 11 kan 20 være af polyurethan. Kabelhylsteret 8 og isoleringsdelen 10 kan også være fremstillet af et andet plastmateriale.Conveniently, the cable casing 8 and insulation portion 10 may be of polyoxymethylene, and insulating molding 11 may be of polyurethane. The cable sheath 8 and the insulating part 10 may also be made of another plastic material.

En hensigtsmæssig fremgangsmåde til tætning af afslutningen af kablet 2 ved hjælp af kabel tætni ngs ind retningen 1 skal i det 25 følgende nærmere omtales, idet kablet 2 f.eks. kan anvendes som det strømforsynende kabel i en motor, f.eks. en tromlemotor.An appropriate method for sealing the termination of cable 2 by means of cable sealing in direction 1 is to be described in the following, with the cable 2 e.g. can be used as the power supply cable in a motor, e.g. a drum motor.

Først fjernes yderkappen 5 i kablet 2's motorende over en 30 større strækning, f.eks. 110 mm, jf. fig. 1. Derefter afisole-res de enkelte ledninger 3 tæt ved yderkappens 5 ende over et kort stykke a, f.eks. 10 mm, dvs. at de enkelte ledningers isolering 7 fjernes, så de metalliske korer 6 er blottede. Herefter fortinnes de enkelte ledningers afisolerede stykker a 35 omhyggeligt én ad gangen. Det er vigtigt, at fortinningsopera-tionen foretages således, at det anvendte loddetin trækker ind under isoleringen 7 i begge sider af det fortinnede stykke a.First, the outer sheath 5 in the motor end of the cable 2 is removed over a larger stretch, e.g. 110 mm, cf. fig. 1. Then the individual wires 3 are stripped close to the end of the outer casing 5 over a short piece a, e.g. 10 mm, i.e. that the insulation 7 of the individual wires is removed so that the metallic cores 6 are exposed. After that, the stripped pieces of each wire of 35 are carefully thinned one at a time. It is important that the thinning operation be carried out so that the solder used extends under the insulation 7 on both sides of the tinned piece a.
