Description
Die Erfindung bezieht sich auf eine biegsame elektrischeAnschlußleitung, die dem Zwecke dient. eine Spannungsvernichtung zwischen Netz und Gerät herbeizuführen.The invention relates to a flexible electrical connection cable, which serves the purpose. bring about a voltage annihilation between the network and the device.
Es ist bereits eine zweidrähtige Leitung bekanntgeworden, deren einer Draht ein Widerstandsdraht ist. Er besitzt eine asbestisolierte Leiterlitze, auf die der Widerstandsdraht schraubenförmig aufgewickelt und von einer äußeren Asbesthülle umgeben ist.A two-wire line has already become known, one of which Wire is a resistance wire. It has an asbestos-insulated stranded conductor which the resistance wire is helically wound and covered by an outer asbestos sheath is surrounded.
Der in diesem Falle verwendete Widerstandsdraht verleiht in seinem vorgeschriebenen Zustand der Anschlußleitung eine nur geringe elektrische und mechanische Festigkeit. Derartige Leitungen sind wegen der zwangsläufigen Anwendung meist sehr schwachen Widerstandsdrahtes nicht oder nur wenig haltbar und kommen deshalb auch nur wenig zur Anwendung.The resistance wire used in this case gives in his prescribed condition of the connection line is only minimal electrical and mechanical Strength. Such lines are usually very large because of the inevitable application weak resistance wire not or only not very durable and therefore also come little use.
Aus diesem Grunde wurde bei der Erfindung von dem Gedanken ausgegangen, zur Erzlielung einer Spannungsvernichtung zwischen Netz und Gerät eine Anschlußleitung zu schaffen, die sich wegen ihrer hohen elektrischen wie auch mechanischen Festigkeit durch eine lange Lebensdauer auszeichnet und bei der Ableitströme durch die Isolation vermieden sind. _ Dies wird nach der Erfindung dadurch erreicht, daß der Litzenleiter zur elektrischen Isolierung eine Seidenumspinnung .unterhalb der Asbestlagen aufweist und daß über der äußeren, den Widerstandsdraht umhüllenden Asbestschicht eine Seidenumspinnung mit darüberliegender Garnumflechtung vorgesehen ist: Die Zeichnung gibt die Erfindung in einem Ausführungsbeispiel in Längsansicht wieder. Die als Seele dienende Kupferlitze eist zunächst mit einer Seidenumspinnung b umgeben, die hier mit Isolierlack c überzogen ist. über ihr liegt eine weitere Seidenumspinnung d, über der dann die Asbestschichten e, f folgen, die mit einem, bei mehreren Litzen zur Kennzeichnung dienenden Seidenfaden g umwickelt sind. Anschließend folgt eine weitere Hülle 1a aus Asbest, auf die dann der Widerstandsdraht i in Schraubenform gewickelt ist. Auf die von dem Widerstandsdraht gebildete Lage fölgt eine Asbestschicht k, die schließlich noch von einer Seidenumspinnung l und der das Ganze umhüllenden Garnumflechtung m umgeben ist.For this reason, the invention was based on the idea of creating a connection line to achieve a voltage destruction between the network and the device, which is characterized by a long service life due to its high electrical and mechanical strength and in which leakage currents are avoided by the insulation. _ This is achieved according to the invention in that the stranded conductor for electrical insulation has a silk covering .below the asbestos layers and that a silk covering with overlying yarn braiding is provided over the outer asbestos layer covering the resistance wire: The drawing shows the invention in an exemplary embodiment in a longitudinal view again. The copper braid, which serves as the core, is initially surrounded by a silk wrapping b, which here is covered with insulating varnish c. Over it lies another silk wrapping d, over which the asbestos layers e, f follow, which are wrapped with a silk thread g, which is used for identification in the case of several strands. This is followed by another sheath 1a made of asbestos, onto which the resistance wire i is then wound in the form of a screw. The layer formed by the resistance wire is followed by an asbestos layer k, which is finally also surrounded by a silk wrapping l and the yarn braiding m which surrounds the whole.
