Description
93596 Päällystetyn avojohdon tiivis pääte. - Tät spännlinhällare tili en belagd luftledning.93596 Coated overhead line sealed terminal. - This account is not paid.
Keksinnön kohteena on päällystetyn avojohdon tiivis pääte, johon kuuluu runkokappale, runkokappaleeseen liittyvä kiinni-tyselin päätteen kiinnittämiseksi eristimeen, liitin haarajoh-don liittämistä varten ja holkkimainen kiinnityspääte, jossa on kiinnityselimet johdon mekaanisten kuormitusten vastaanottamiseksi .The invention relates to a sealed end of a coated open conductor comprising a body, a fastening member associated with the body for attaching the terminal to an insulator, a connector for connecting a branch line and a sleeve-like fastening end with fastening means for receiving mechanical loads on the conductor.
Tällaisia päätteitä käytettäessä poistetaan johdon päästä johtoeristys tietyltä matkalta ja tiivistys tehdään erillisillä suojilla kuten esim. kutistemuovilla, jolla päätteen ja johdon liittymäkohta ympäröidään.When using such terminals, the cable insulation is removed from the end of the cable a certain distance and the sealing is done with separate shields such as, for example, shrink plastic, which surrounds the connection point between the terminal and the cable.
Haarajohto liitetään erillisellä liittimellä tai kaapelikengil-lä, jotka on puristettava työkalulla johdon ympärille.The branch cable is connected with a separate connector or cable lug, which must be pressed around the cable with a tool.
Tunnetuilla päätteillä sähköinen kontakti on huono useiden liitosten ylimenokohtien takia. Tunnetuissa päätteissä on vähintään 3-4 kappaletta ylimenojen aiheuttamia ylimenovastuksia. Lisäksi tunnetut päätteet ovat suhteellisen pitkiä, jolloin niiden asentamiseen liittyy hankaluuksia.With known terminals, the electrical contact is poor due to the transition points of several joints. Known terminals have at least 3-4 crossing resistors caused by crossovers. In addition, the known terminals are relatively long, which makes them difficult to install.
Keksinnön tarkoituksena on saada aikaan parannettu tiivis pääte, jossa voidaan käyttää hyväksi sinänsä tunnettua automaattisesti lukittuvaa kiinnitysholkkia johdon kuormitusten vastaanottamiseksi, samalla kun ylimenovastusten määrä voidaan vähentää kahteen ja päätteen pituutta lyhentää asennettavuuden parantamiseksi.The object of the invention is to provide an improved sealing terminal in which an automatically locking fastening sleeve known per se can be used to receive line loads, while the number of transition resistors can be reduced to two and the length of the terminal can be shortened to improve installability.
Tämä tarkoitus saavutetaan oheisessa patenttivaatimuksessa 1 esitettyjen tunnusmerkkien perusteella.This object is achieved on the basis of the features set out in the appended claim 1.
Epäitsenäisissä patenttivaatimuksissa on esitetty keksinnön 2 93596 edullisia toteutustapoja, jotka liittyvät keksinnön parhaana pidettyyn suoritusesimerkkiin.The dependent claims disclose preferred embodiments of the invention 2 93596, which relate to a preferred embodiment of the invention.
Seuraavassa keksintöä selostetaan lähemmin viittaamalla oheisiin piirustuksiin, joissa kuvio 1 esittää keksinnön mukaista tiivistä päätettä sivulta nähtynä ja osittain leikattuna; kuvio 2 esittää samaa päätettä päältä nähtynä.In the following, the invention will be described in more detail with reference to the accompanying drawings, in which Figure 1 shows a compact end according to the invention seen from the side and partly in section; Figure 2 shows a top view of the same terminal.
Päätteeseen kuuluu runkokappale 1, joka on tehty alumiinipro-fiilista ja jossa on kiinnityselin 3 päätteen kiinnittämiseksi eristimeen.The terminal comprises a body 1 made of aluminum profile and having a fastening member 3 for fastening the terminal to the insulator.
Rungon 1 pituussuuntaisena jatkeena on holkkimainen kiinnitys-pääte 2, johon kuuluu kartioholkki, jonka sisällä on kiilakap-paleet 7, jotka puristuvat vasten johtimen pintaa. Jousi 8 kuormittaa kiilakappaleita 7 kohti kartion 2 supistumissuuntaa, jolloin johtoa sisään työnnettäessä kiilakappaleet 7 pääsevät väistymään jousen 8 puristuessa kasaan. Kun johtoa vedetään ulospäin, kiilakappaleet 7 puristuvat suurella voimalla vasten johtimen pintaa, mikä aikaansaa mekaanisen vetorasituksen vastaanottavan lukituksen. Tällaiset holkkimaiset kiinnityspäät-teet 2 ovat ennestään tunnettuja. Keksinnössä sitä käytetään kuitenkin muodostamaan uudenlainen yhdistelmä runkokappaleen 1 kanssa. Tätä varten rungossa 1 on johdonpään vastaanottava tila 9 holkkimaisen kiinnityspäätteen 2 aksiaalisella jatkeella. Runkokappaleen 1 kierrerei'issä olevien momenttiruuvien 10 päät ulottuvat tilan 9 sisään ja aikaansaavat sähköisen kontaktin, kun ruuvit 10 kiristetään vasten tilassa 9 olevaa johdon päätä.The longitudinal extension of the body 1 is a sleeve-like fastening terminal 2 comprising a conical sleeve with wedge pieces 7 inside which press against the surface of the conductor. The spring 8 loads the wedge pieces 7 towards the constriction direction of the cone 2, whereby when the wire is inserted, the wedge pieces 7 can be deflected when the spring 8 is compressed. When the wire is pulled outwards, the wedge pieces 7 are pressed with great force against the surface of the wire, which provides a locking mechanism which receives the mechanical tensile stress. Such sleeve-like fastening terminals 2 are known in the art. In the invention, however, it is used to form a novel combination with the body 1. For this purpose, the body 1 has a cable receiving space 9 with an axial extension of the sleeve-like fastening terminal 2. The ends of the torque screws 10 in the threaded holes of the body 1 extend into the space 9 and provide electrical contact when the screws 10 are tightened against the end of the wire in the space 9.
Haarajohdon liittämistä varten on runkoon 1 kiinnitetty ruuveilla 14 liitinkappale 4 (joita esitetyssä tapauksessa on kaksi rinnakkain). Liitinkappaleissa 4 ja rungossa 1 on ensim- li 93596 3 mainen leukapari, jonka leukojen vastinpinnoissa on johdin-eristeen läpäisevät hampaat 5. Toisen leukaparin leukojen vastinpintojen 6 väliin voidaan kiinnittää valokaarisuojasarvi tai työmaadoitusjohto. Hampaiden 5 pituus voi olla riittävä läpäisemään haarajohdon päällyste, jolloin haarajohdon päällystettä ei tarvise poistaa.For connecting the branch line, a connector 4 (which in the case shown is two in parallel) is fastened to the body 1 with screws 14. The connectors 4 and the body 1 have a first pair of jaws 93596 3, the jaw mating surfaces of which have teeth 5 which penetrate the conductor insulation. An arc shield or a work earth wire can be attached between the jaw mating surfaces 6 of the second jaw pair. The length of the teeth 5 may be sufficient to penetrate the branch line coating, in which case it is not necessary to remove the branch line coating.
Kiinnityskartio 2 on liitetty runkoon 1 seuraavasti. Kiinnitys-kartion tai -hoikin 2 tyviosaa ympäröi lukitusrengas 11, joka on kiinnitetty ruuveilla 13 rungon 1 päädyssä oleviin korvak-keisiin 15. Kiinnityskartion tai -hoikin 2 tyvessä on rengasmainen kohouma 12, joka sijaitsee rungon 1 päädyn ja lukitus-renkaan 11 välissä. Tämä rengasmainen kohouma 12 tarttuu siis lukitusrenkaan 11 taakse ja siirtää johdon vetokuormituksen hoikista tai kartiosta 2 lukitusrenkaaseen 11, josta kuormitus siirtyy ruuvien 13 kautta runkokappaleeseen 1. Kuitenkaan sähköistä kontaktia ei tarvitse viedä hoikin tai kartion 2 ja runkokappaleen 1 välisen ylimenokohdan yli, vaan sähköinen kontakti saadaan suoraan alumiinirunkoon 1, kun johdon pää sijaitsee tilassa 9.The mounting cone 2 is connected to the frame 1 as follows. The base of the mounting cone or sleeve 2 is surrounded by a locking ring 11 which is fastened with screws 13 to lugs 15 at the end of the body 1. At the base of the mounting cone or sleeve 2 there is an annular protrusion 12 located between the end of the body 1 and the locking ring 11. This annular protrusion 12 thus grips behind the locking ring 11 and transfers the tensile load of the cable from the sleeve or cone 2 to the locking ring 11, from where the load is transferred via screws 13 to the body 1. However, electrical contact does not have to be made across the sleeve or cone 2 and the body 1 directly to the aluminum body 1 when the end of the wire is in space 9.
Kiilakappaleilla 7 voi olla johdon päällysteen läpäisevät hampaaat. Tämä ratkaisu on erityisen käyttökelpoinen tapauksessa, jossa runko 1 ja kiinnityskartio 2 ovat samaa kappaletta. Tällöin johdon päätä ei tarvitse kuoria, vaan riittävä sähköinen kontakti saadaan päällysteen läpäisevillä hampailla.The wedge pieces 7 may have teeth that penetrate the coating of the wire. This solution is particularly useful in the case where the body 1 and the mounting cone 2 are in one piece. In this case, the end of the cable does not need to be peeled, but sufficient electrical contact is obtained with the teeth penetrating the coating.
