Description
Verfahren zur Herstellung von leicht biegsamen elektrischen Leitungen Für manche Verwendungszwecke, z. B. für die Verbindung von einem Schweißgenerator zu den Schweißelektrodenhaltern, werden besonders leicht bewegliche Leitungen benötigt, um eine bequeme und für den Bedienenden nicht so rasch ermüdende Handhabung und Führung der Geräte zu gewährleisten. Hierfür ist es bekannt, neben den üblichen sogenannten Schweißleitungen die blanken Leiter in Form von Kupferlitzen aus möglichst feinen Drähten lose in Gummischläuche einzuziehen. Die Herstellung derartiger Leitungen von Hand, die meistens erst am Verwendungsort durchgeführt zu «-erden pflegt, ist jedoch längenmäßig begrenzt und umständlich.Process for the production of easily flexible electrical cables For some uses, e.g. B. for the connection of a welding generator to the welding electrode holders, flexible lines are required, about comfortable handling and not so quickly tiring for the operator Ensure management of the devices. It is known for this, besides the usual so-called welding lines the bare conductors in the form of copper strands as possible to pull fine wires loosely into rubber hoses. The manufacture of such lines by hand, which is usually only "grounded" at the place of use but limited in length and cumbersome.
Gemäß der Erfindung wird der genannte Nachteil dadurch vermieden, daß auf den Leiter vor dem Aufbringen des Isoliermantels z. B. aus Gummi oder gleichwertigen Stoffen ein beim Erwärmen gasabgebender chemischer Stoff, z. B. Zinkkarbonat, aufgebracht wird, so däß beim nachträglichen Erwärmen nach Aufbringen des Isoliermantels, z. B. Vulkanisieren, eine Aufweitung des Isoliermantels erfolgt. Hierdurch wird erreicht, daß der Leiter lose in einem Isoliermantel liegt, so daß die Leitung leicht biegsam ist. Der als Tre;ibmättel wirkende Stoff kann in Form einer Paste oder eines Pulvers auf den Leiter aufgebracht werden. Der Leiter kann auch mit einer Textilbandumspinnung umgeben werden, welche mit dem als Treibmittel wirkenden Stoff bestrichen wird. Durch die Erwärmung nach Aufbringen des Mantels wird bei Verwendung von Zinkkarbonat Kohlensäure als sogenanntes Treibmittel frei, und Zinkoxyd bleibt als unschädlicher Bestandteil zurück, der weder den Leiter noch den Isoliermantel angreift. Bei entsprechender Bemessung der TNIenge des Treibmittels wird eine Aufblähung des Mantels erreicht, die eine dauernde Dehnung bewirkt. Dadurch wird es möglich, den geringfügigen Abstand zwischen Leiter und umgebender Mantelschicht zu erhalten, der die gewünschte leichte Beweglichkeit schafft.According to the invention, the disadvantage mentioned is avoided by that on the conductor before applying the insulating sheath z. B. made of rubber or equivalent Substances a chemical substance that emits gas when heated, e.g. B. zinc carbonate applied is, so däß with subsequent heating after applying the insulating jacket, z. B. vulcanization, an expansion of the insulating jacket takes place. This achieves that the conductor lies loosely in an insulating jacket, so that the line is easily flexible is. The substance acting as Tre; ibmättel can be in the form of a paste or a powder be applied to the conductor. The conductor can also be wrapped in a textile band are surrounded, which is coated with the substance acting as a propellant. When using zinc carbonate, the heating after applying the jacket Carbonic acid is released as a so-called propellant, and zinc oxide remains as harmless Component back that does not attack either the conductor or the insulating jacket. With the appropriate Dimensioning of the amount of propellant becomes an inflation of the Mantle reached, which causes a permanent stretch. This makes it possible to use the to maintain a slight distance between the conductor and the surrounding cladding layer, that creates the desired easy mobility.
