Joustava såhkOkaapeliFlexible electrical cable
Keksinttt koskee erittain joustavaa sahkOkaapelia tal vastaavaa johdinta kaapelin tai johtimen rakenteeseen 5 sovitettuine eristavaa ainetta olevine kimmoisine vaippoi-neen. Keksinnttn kohteena on lisaksi menetelma edeliamaini-tun tyyppisen kaapelin tai johtimen valmistamiseksi.The invention relates to a conductor corresponding to a highly flexible electric cable with elastic sheaths of insulating material arranged in the structure 5 of the cable or conductor. The invention further relates to a method for manufacturing a cable or conductor of the aforementioned type.
Erittain joustavia kaapeleita ja johtimia kaytetaan ennenkaikkea liitos- tai sydttOjohtoina kaikkialla siel-10 la, missa kayttajan kaytGssS tulee suorittaa kierto- tai heilahdusliikkeita. Erityinen kayttdalue tailaisille kaa-peleille ja johtimille on laaketieteen alue, missa vaadi-taan mahdollisimman vapaata liikkuvuutta sMhkOenergialla syOtetyille mittaus-, ohjaus- tai kasittelylaitteille. Ta-15 ma vaatimus patee seka yksijohtimisille, esimerkiksi koak-siaalisille sydttttjohtimille kirurgisia instrumentteja vårten etta myOs monijohtimisille, paastaen esimerkiksi mittauspailia varustetuille datakaapeleille, joita kaytetaan laaketieteellisessa tutkimuksessa.Highly flexible cables and conductors are primarily used as connecting or core conductors wherever the user must perform rotational or oscillating movements. A special area of application for such cables and conductors is the field of medicine, in which the greatest possible freedom of movement is required for measuring, control or handling devices supplied with sMhOOenergy. Ta-15 ma requirement applies to both single-conductor, e.g. coaxial core conductors for surgical instruments and also myOs multiconductor, fasting, for example, to data cables with measuring pins used in medical research.
20 Tailaisten liitos- tai yhdysjohtimien oleellisen vapaata liikkuvuutta ei ole tahan asti onnistuttu saavut-tamaan mm. siksi, etta liikkuvuuden tai joustavuuden li-saantyessa kaapelin vetolujuus heikkenee ja taten sen kayttOturvallisuus esimerkiksi myOs mainittuja tarkoituk-: 25 sia vårten on kyseenalainen.20 It has not been possible to achieve the substantially free movement of connecting or connecting cables. therefore, that as the mobility or flexibility increases, the tensile strength of the cable decreases and its use, for example for these purposes, is questionable.
Jos kaapelin vetolujuutta kasvatetaan, kuten on pitkaan ollut tunnettua, esimerkiksi vaippaan sovitetuilla vastaavasti vetolujilla saikeilia tai punoksilla, niin tailainen varustus estaa esimerkiksi mittapaata kierret-30 taessa liitosjohtoon siirtyneet kiertoliikkeet. Kaapelin murtumat erityisesti kaapelien paissa ovat usein seurauk-sena.If the tensile strength of the cable is increased, as has long been known, for example with strands or braids with correspondingly tensile strengths arranged in the sheath, such equipment prevents, for example, the torsional movements transferred to the connecting cable during threading. Cable fractures, especially at cable ends, are often the result.
KeksinnOn tehtavana onkin siten muodostaa johdan-nossa mainitun kaltaiset kaapelit tai johtimet sellaisik-35 si, etta ne sallivat vaaditun liikkuvuuden mielivaltaisiin 2 91569 suuntiin, mutta ovat kuitenkin samanaikaisesti viela riit-t3v3n vetolujia.It is therefore an object of the invention to provide cables or conductors of the type mentioned in the introduction in such a way that they allow the required movement in arbitrary 2 91569 directions, but at the same time are still sufficiently tensile.
Tama tehtava ratkaistaan keksinnOn mukaisesti siten, etta ainakin yhden vaipan sisapuolinen paailipinta on 5 peitetty pituussuuntaisilla reunoilla varustetuksi nauhak-si muodostetulla ja vaippaan liitetylia, suunnatulla ja sintratulla fluoripolymeeria olevalla kalvolla. Tama toi-menpide johtaa likimain vapaaseen kulloisenkin vaipan kiertyvyyteen esimerkiksi kaapelin sydamen, johtimen, 10 eristyksen jne. ympari. Aksiaalisuuntaiset liikkeet saman-aikaisen kiertymisen yhteydessa siirtyvat ongelmitta kek-sinnttn mukaisten kaapelien tai johtimien toimesta. Samanaikaisesti on esimerkiksi vaaditun joustavuuden johdosta kautsumateriaalista valmistettu ja siten sinaiiaan kimmoi-15 sella keksinnOn kaapelin vaipalla kohonnut vetolujuus. Nama ovat ominaisuuksia, jotka esimerkiksi myiis kasittely-laitteiden (robottien) alalla naissa yhteyksissa tavan-omaisine pitkine kayttOaikoineen ja alituisesti vaihtele-vine liikeratoineen varmistavat keksinnOn mukaisten kaape-20 lien tai johtimien edullisen kaytOn.According to the invention, this object is achieved in that the inner surface of the at least one sheath is covered with a film of fluoropolymer formed as a strip with longitudinal edges and attached to the sheath, oriented and sintered. This procedure results in an approximately free rotation of the respective sheath around, for example, the cable core, conductor, insulation, etc. The axial movements in connection with the simultaneous rotation are transmitted without problems by the cables or conductors according to the invention. At the same time, for example, due to the required flexibility, the tensile strength of the cable sheath of the invention is made of a rubber material and thus has an increased resilience. These are features which, for example, would be advantageous in the field of handling devices (robots) in female contexts with their conventional long operating times and constantly varying trajectories ensuring the advantageous use of the cables or conductors according to the invention.
Suuri osa esimerkiksi keksinndn mukaisen kaapelin vaippaan aksiaalisesti tai radiaalisesti kohdistetuista liikevoimista tulevat vaiittOmSsti sen vastaanottamiksi ja ymparOity ydin tai myds herkkS johdin vapautuvat oleelli-25 sesti ulkoisista voimista. Keksinndn mukaisesti ehdotettu toimenpide tuo mukanaan viela muitakin etuja. Silia fluo-ripolymeeria olevan kalvon mukaanottaminen, siis aineen, joka soveltuu k&ytettavSksi korkeissa lSmpdtiloissa, mer-kitsee samanaikaisesti herkan ytimen parempaa suojausta 30 ulkoisia lampOtilavaikutuksia ja kemiallisesti aggressii-visia aineita vastaan. Talla on erityinen merkityksensa esimerkiksi kirurgisen laaketieteen liitosjohtimille, jos-sa instrumentit kaytdn jaikeen niihin liittyvine liitos-johtimineen taytyy steriloida kohotetuissa lampdtiloissa 35 ja joilta taman jaikeen edellytetaan jalleen taytta toi- 3 91569 mintakykya. Nykyisin tavanomaiset johtimet t&yttåvflt kaik-ki nSma vaatimukset ainoastaan lyhytaikaisesti tai rajoi-tetusti, koska esimerkiksi sterilointitoimenpide johtaa yha uudelleen viereisten yksittaiselementtien liimautumi-5 seen kerrosrakenteessa, minka johdosta naiden johtimien kaytdlle vaittamatdn liikkuvuus vastaavasti taipuisuus merkittavasti huononee.For example, much of the kinetic forces applied axially or radially to the sheath of a cable according to the invention are silently received by it and the surrounding core or myds sensitive conductor is substantially released from external forces. According to the invention, the proposed operation brings even further advantages. The inclusion of a film of silica fluoropolymer, i.e. a substance suitable for use in high temperature conditions, simultaneously means better protection of the sensitive core against the effects of external temperatures and chemically aggressive substances. This is of particular importance, for example, for surgical medicine splice leads, where the instruments used and their associated splice conductors must be sterilized in elevated lamp rooms 35 and from which this yoke is required to again perform full performance. Today, conventional conductors meet all the requirements only for a short time or to a limited extent, because, for example, the sterilization operation leads again and again to the gluing of adjacent individual elements in a layered structure, which significantly reduces the mobility of these conductors.
Pituussuuntainen nauhamainen kalvo voi olla sovi-tettu kunkin vaipan sisapinnalle siten, etta nauhan reunat 10 ovat tylpasti toisiaan vasten. Erityisen edullista on kek-sintda edelleen kehitettaessa kuitenkin, jos pituussuun-taiset nauhan reunat limittyvat keskenaan. Tama tuo lisa-varmuutta valmistusprosessiin ja varmistaa vaipan sisapin-nan taydellisen peittamisen ja siten vapaan liikkuvuuden.A longitudinal strip-like film may be fitted to the inner surface of each sheath so that the edges 10 of the strip are bluntly against each other. However, it is particularly advantageous for further development of the invention if the longitudinal edges of the strip overlap. This brings Lisa security into the manufacturing process and ensures complete coverage of the inner surface of the sheath and thus free movement.
15 Tarkoituksenmukaisesti koostuu keksinndn mukaisesti sovitettu nauhamainen kalvo vastaekstruusiolla ja taman jaikeiselia valssauksella tyOstetysta fluoripolymeerista, esimerkiksi polytetrafluorieteenista yksinåan tai seospo-lymeerista.Suitably, the strip-like film adapted according to the invention consists of a fluoropolymer produced by counter-extrusion and its rolling, for example polytetrafluoroethylene alone or a blended polymer.
20 Tarvittavan vetolujuuden saavuttamiseksi kaapelin tai johtimen kerrosrakenteeseen sovitetun kalvon pituus-suunnassa on osoittautunut edulliseksi venyttaa tata aina 2 000 %:iin asti edullisesti vaiilia 300 - 1 000 %. Vas-taava venytys voi tapahtua lisaksi poikittain nauhan suun-25 taan nahden, jos keksinndn toteuttamiseksi osoittautuisi tarkoituksenmukaiseksi esimerkiksi kohottaa kalvon huokoi-suutta ja siten parantaa mekaanista liitosta kulloiseenkin vaippaan.In order to achieve the required tensile strength in the longitudinal direction of the film arranged in the layer structure of the cable or conductor, it has proved advantageous to stretch the tile up to 2,000%, preferably 300 to 1,000%. The corresponding stretching can additionally take place transversely to the direction of the strip, if it proves expedient to carry out the invention, for example to increase the porosity of the film and thus to improve the mechanical connection to the respective sheath.
KeksinnOn mukaisesti sovitetun kalvon nimellispaino 30 on edullisesti oikaistussa tai venytetyssa ja sintratussa tilassa 0,2 - 0,7 g/cm3. Jos venytys tapahtuu ainoastaan nauhan suunnassa, kuten on erityisen edullista, niin vetolu juuden suhde nauhamaisen kalvon venytyssuunnassa ja poikittain tahan nahden vaiilia 10 - 15:1.The nominal weight 30 of the film arranged according to the invention is preferably in the straightened or stretched and sintered state 0.2 to 0.7 g / cm 3. If the stretching takes place only in the direction of the strip, as is particularly advantageous, then the ratio of the tensile strength in the stretching direction of the strip-like film and transversely to any of the strips is 10 to 15: 1.

Venytetyn ja sen jaikeen sintratun nauhamaisen kal-von vahvuus on keksinnOn mukaisesti 15 - 250 μπι, edulli-sestl 30 - 100 μπι. Tunnettujen elementtien suhteen vetolu-juuden kohottamiseksi, kuten sSikeiden tai punosten, mer-5 kltsee tama kaapelin tai johtimen kerrosrakenteessa taysin huomaamatonta toimenpidetta. Taten voidaan esimerkiksi vaaditut ulkomitat ongelmitta sailyttaa parannettaessa kayttdominaisuuksia kuitenkin oleellisesti.According to the invention, the strength of the stretched and sintered strip-like film according to the invention is 15 to 250 μπι, preferably 30 to 100 μπι. In order to increase the tensile strength of the known elements, such as s-braids or braids, this is a completely inconspicuous measure in the layer structure of the cable or conductor. For example, the required external dimensions can be easily maintained, however, while substantially improving the usability.
Poikittaissuunnassa tapahtuvan lisaveny tyksen ohel-10 la huokoisuuden kohottamiseksi voidaan nauhan suunnassa venytetty ja sintrattu kalvo myds perforoida, esimerkiksi niin, etta kalvo ennen asennusta johdetaan neulatelan ia-pi.In order to increase the porosity of the additional stretch in the transverse direction, the film stretched and sintered in the direction of the strip can be perforated, for example so that the film is guided on the needle roll ia-pi before installation.
KeksinnOn mukainen kaistamainen kalvo on kaapelin 15 tai johtimen kerrosrakenteessa asetettavissa kulloinkin vaatimusten mukaisesti mielivaltaiseen paikkaan. Jos kaa-peli koostuu esimerkiksi useista sinansa joustavista ohuista saikeista ja tama ydin on peitetty kimmoisalla vaipalla, sovitetaan nauhamainen, venytetty ja sintrattu 20 kalvo edullisesti ytimen puoleiselle vaippapinnalle. Sinansa kimmoisan ja joustavan vaipan kalvon varmistaman vetolujuuden ohella on vaippa tamån toimenpiteen johdosta varsin pitkasti vapaasti kierrettavissa ytimen suhteen.The strip-like film according to the invention can be placed in an arbitrary position in the layer structure of the cable 15 or conductor in accordance with the requirements in each case. For example, if the kaa-game consists of a plurality of flexible thin strands of the sinus and this core is covered with an elastic sheath, a strip-like, stretched and sintered film 20 is preferably applied to the core-side sheath surface. In addition to the tensile strength provided by the resilient and flexible sheath film, the sheath is freely rotatable relative to the core for a long time as a result of this operation.
Jos johtimessa on sisajohtimen ja ulkojohtimen ko-25 aksiaalinen sovitus, niin nauhamainen kalvo sovitetaan tarkoituksenmukaisesti ulkojohtimen ja siihen liittyvan eristyksen valiin.If the conductor has a coaxial fit of the inner conductor and the outer conductor, then the strip-like film is suitably matched between the outer conductor and the associated insulation.
Tarkoituksenmukaiseksi keksinndn mukaisen kaapelin tai johtimen valmistamiseksi on osoittautunut menetelma, 30 jolle on tunnusomaista, etta ennen kunkin kimmoisen vaipan sovitusta venytetty ja sintrattu nauhamainen kalvo sovite- taan kulloisenkin alusrakenteen - ydin, johdin - paaile pituussuunnassa ja taman jaikeen niiden paaile muodoste-taan vaiittOmasti eristava vaippa ja sen jaikeen sen raa-35 ka-aine verkkoutetaan, jolloin vaippaa muodostettaessa 5 91569 ja/tai liittyv&ssa verkkoutuksessa vaipan sisSpuolella oleva nauhamainen kalvo liimautuu tai hitsautuu vaippaan. Kun raaka-aine verkkoutetaan, vaippaa muodostettaessa ja/tai taman jaikeisessa verkkoutuksessa, vaipan sisapuo-5 lella oleva nauhamainen kalvo liimautuu tai hitsautuu vaippaan. Jos, kuten silikonikautsukin tapauksessa, kaut-sukkiaine levitetaan kylmana nauhamaiselle kalvoile ja vasta taman jaikeen tapahtuu lampdkasittely verkkoutumi-sen aikaansaamiseksi, voi olla edullista suorittaa jo pai-10 koilleen sovitetun nauhamaisen kalvon esiiammitys.A method for producing a cable or conductor according to the invention has proved expedient, characterized in that before stretching each resilient sheath, the stretched and sintered strip-like film is arranged and its raw material is crosslinked, whereby, when forming the sheath and / or in the associated crosslinking, the strip-like film inside the sheath is glued or welded to the sheath. When the raw material is crosslinked, during the formation of the jacket and / or in its loose crosslinking, the strip-like film on the inside of the jacket is glued or welded to the jacket. If, as in the case of silicone rubber, the rubber stock is cold-applied to the strip-like films and only this material is subjected to lamp treatment to effect crosslinking, it may be advantageous to pre-pre-position the strip-like film already fitted.
Keksintoa kuvataan lahemmin kuvioissa 1 ja 2 suo-ritusmuotoesimerkkeina esitettyjen kaapeli- ja johdinra-kenteiden avulla.The invention is described in more detail by means of the cable and conductor structures shown in Figures 1 and 2 as exemplary embodiments.
Kuvio 1 esittaa monisaikeisen sdhkdkaapelin, jonka 15 saikeet 1 kerrattuina tai niputettuina pidetaan yhdessa nauhalla 2. Taman saiesiteen paaile on muodostettu palmik-ko 3, mekaaniseksi suojaksi tai myds hairidsuojauksen aikaansaamiseksi, jos tailaista kaapelia tulee kayttaa jous-tavana liitosjohtona mittaus- tai ohjauslaitteita vårten.FIG.
20 Vaippa 4 esimerkiksi verkkoutetusta silikonikautsukista on muodostettu vaaditun joustavuuden johdosta vastaavasti ja on tasta syysta myds saikeiden suunnassa kimmoisa. Tama vaipan kimmoisuus on epaedullista sikaii, kun kaapeliin kaytdssa kohdistuu vetojannityksia ja vaipan ympardima 25 ydin ei kykene mukautumaan naihin venytyksiin. Tosin voi-taisiin vaipan kimmoisuutta vahentaa vastaavasti lisaamai-ia tayteaineita vaippaseokseen, mutta tåma toimenpide joh-taa kuitenkin myds muiden materiaaliominaisuuksien muutok-siin, joita esimerkiksi myds vaaditun korkean joustavuuden 30 johdosta ei voida juuri hyvaksya.The sheath 4, for example of crosslinked silicone rubber, is formed correspondingly due to the required flexibility and is therefore resilient in the direction of the myds strands. This resilience of the sheath is disadvantageous when the cable is subjected to tensile stresses during use and the core 25 surrounding the sheath is unable to adapt to these stretches. Admittedly, the resilience of the sheath could be reduced by adding additional fillers to the sheath mixture, but this operation leads to changes in other material properties which, for example, are hardly acceptable due to the high flexibility required.
Tassa tilanteessa keksintd tulee avuksi, koska sii-na vaipan 4 ja punoksen 3 vaiiin on sovitettu venytetty ja sintrattu kalvo 5 esimerkiksi tetrafluorietyleenipolymee-rista. Tama kalvo 5 toimii erinomaisena liuku- tai erotus-35 kalvona siten, etta vaippa 4 ja punos 3 ovat kaytanndssa 6 91569 vapaasti kierrettSvissé; johtuen mekaanisesta liitokses-taan vaipan 4 sisåpinnan kanssa ottaa se samanaikaisesti vetoelementin toiminnon kaapelirakenteessa, mika merkitsee oleellista vaipan 4 kinunoisuuden rajoitusta. Vaippaa 4 5 muodostettaessa kalvon 5 johdosta vaippamateriaali ei voi myOskaan tunkeutua palmikkoon vaikuttaakseen negatiivises-ti kaapelin taipuisuuteen.In this situation, the invention is helpful because a stretched and sintered film 5 of, for example, a tetrafluoroethylene polymer is arranged in the sheath of the sheath 4 and the braid 3. This film 5 acts as an excellent sliding or separating film 35, so that the jacket 4 and the braid 3 are freely rotatable in use 6 91569; due to its mechanical connection with the inner surface of the sheath 4, it simultaneously assumes the function of a traction element in the cable structure, which means a substantial limitation of the kinematicity of the sheath 4. When forming the sheath 4 5 due to the film 5, the sheath material cannot also penetrate the braid to negatively affect the flexibility of the cable.
Kalvo 5 venytetaan ennen sintrausta tai samanaikaisesti taman lampOkasittelyn kanssa. Tailainen kalvo on lu-10 kuunottamatta saavutettua korkeaa vetolujuutta taten huo-koinen siten, etta syntyy luja liitos vaipan kanssa vaip-pamateriaalia levitettaessa tai verkkoutettaessa lampOkasittelyn aikana. Koska kalvo 5 lisaksi ulottuu vaipan 4 koko sisapinnalle ja siten kaapelin kehaile jakautuu usei-15 ta liitospisteita, jotka varmistavat liitoksen vaipan 4 ja kalvon 5 vaiilia, voi keksinnOn mukaisesti tuettu vaippa 4 kaytetyn vaippa-aineen kimmoisuudesta huolimatta vastaan-ottaa taita merkittavia vetovoimia ja siten poistaa kaapelin ytimelta vetorasituksen. Huolimatta varsin laajasta 20 vaipan 4 liikevapaudesta punoksen 3 paalia ei yleisesti ottaen vaipan 4 ja sen alla olevan ytimen vaiinen voimien valitys mene hukkaan.The film 5 is stretched before sintering or simultaneously with this lamp treatment. The tile film is porous without hearing the high tensile strength achieved without hearing, so that a strong connection with the sheath is formed when the sheath base material is applied or crosslinked during the lamp treatment. In addition, since the membrane 5 extends over the entire inner surface of the sheath 4 and thus the cable circumference is distributed by several connection points which secure the splices of the sheath 4 and the membrane 5, the sheath 4 supported according to the invention can receive significant tensile forces and thus removes the tensile stress from the cable core. Despite the rather wide freedom of movement of the sheath 4, the bale of the braid 3 is generally not wasted by the silent complaint of forces by the sheath 4 and the core below it.
Kuviossa 2 on esitetty sahkOinen syOttOjohto, joka on rakenteeltaan koaksiaalinen.Figure 2 shows an electric supply line with a coaxial structure.
25 Punosjohtimena muodostettu sisajohdin 6 on jousta- van eristyksen 7 ympOrOima, jolle esimerkiksi vuorottele-vasti toistensa viereen on sovitettu ulkojohtimen saikeita 8 ja lasikuitusaikeita 9 niiden kiinnittamiseksi ulkopin-taan. Taman ytimen paaile on joustava vaippa 10 muodostet-30 tu ulkovaipaksi, jolloin keksinnOn ehdotuksen mukainen kalvo 11 jalleen ottaa liuku- tai erotuskalvon tehtavan vaipan 10 ja ulkojohtimen 8 vaiilia ja samanaikaisesti vetoelementin tehtavan, joka kalvo on liitetty vaipan si-sapintaan mekaanisesti koko kehaita.The inner conductor 6 formed as a braided conductor is surrounded by a flexible insulation 7, on which, for example, the strands 8 of the outer conductor and the strands of fiberglass 9 are arranged alternately next to each other to attach them to the outer surface. The core of this core is a flexible sheath 10 formed as an outer sheath, whereby the film 11 according to the invention again takes over the function of the slide 10 of the sliding or separating film sheath and the outer conductor 8 and at the same time acts as a traction element mechanically connected to the sheath.

Viitenumerolla 12 on yleisesti merkitty kalvon 11 nauhan reunojen limityspaikkaa. Tama synnytetaan siten, etta pituussuuntaisen kalvon sovittamiseksi ulkojohtimel-le 8, 9 suppilomaisen pituussuuntaisen tyOkalun avulla 5 valitaan nauhan leveys, joka on suurempi kuin johtimen ke-ha tasså kohdassa.Reference numeral 12 generally denotes the overlapping location of the edges of the strip of film 11. This is generated by selecting a strip width greater than that of the conductor at this point by means of a funnel-shaped longitudinal tool 5 to fit the longitudinal film to the outer conductor 8, 9.
Nauhan reunojen limitykselia aikaansaadulla kalvol-la 11 on tassa kayttdtapauksessa lisaksi tehtavana suojata koaksiaalista johdinrakennetta kohonneen lampdtilan vai-10 kutuksilta esimerkiksi laaketieteellisten laitteiden de-sinfioinnin yhteydessa, mika voi johtaa ulkojohtimen lii-mautumiseen vaippaan ja/tai sisajohtimen eristykseen ja siten heikentaa johtimen joustavuutta ja palautuvuutta.In this case, the film 11 provided by the overlapping edge of the strip additionally serves to protect the coaxial conductor structure from the effects of the elevated lamp space, for example in connection with the disinfection of .
Kuvioissa 1 ja 2 esitetyt sahkdjohtimet ovat jous-15 tavuuden johdosta tarkoituksehmukaisesti metallisista ai-neista valmistettuja punosjohtimia. Kuitenkin myOs valo-johtimia voidaan edullisesti kayttaa keksinnOn mukaisesti muodostettujen kaapelien tai johtimien yhteydessa. TailOin ydinta mekaanisten kuormitusten suhteen suojaava, venytet-20 ty ja sintrattu kalvo muodostaa oleellisen suojan herkaile valojohtimelle.The electric conductors shown in Figures 1 and 2 are purposefully braided conductors made of metallic materials due to their flexibility. However, myOs light conductors can be advantageously used in connection with cables or conductors formed according to the invention.
