Description
Verfahren zur Herstellung von mehradrigen verdrallten Leitungen Die Herstellung von Leitungen mit mehreren verdrallten Leitern bereitet bei der üblichen Verseilung der Leiter Schwierigkeiten, da je nach dem Verseilwinkel an dem Verseilpunkt auf die Leiter oder Adern ein stärkerer Druck an der Berührungsfläche ausgeübt wird. Eine Verseilung, bei der die Leiter zwanglos im Abstand voneinander einlaufen, ist bisher nicht möglich gewesen, aber erwünscht. Es sind mehradrige verdrallte Leitungen bekannt, bei denen die Isolierung zwischen den im Abstand voneinander verdrallten einzelnen Leitern und der die Leitung umgebende Isoliermantel von einem einheitlichen zusammenhängenden Isolierstoff gebildet ist. Bei diesen Leitungen ist der äußere Isoliermantel an einzelnen Stellen mit schräg nach innen verlaufenden Einschnitten versehen, und die Verdrallung wird erst nach der Herstellung der Isolierung vorgenommen. Hierdurch ergibt sich eine schädliche Beanspruchung der Isolierung der Leitung. Process for the production of multi-core twisted cables The Manufacture of cables with several twisted conductors prepares for the usual Stranding of the conductors Difficulties, as this depends on the stranding angle at the stranding point stronger pressure is exerted on the conductors or veins at the contact surface. A stranding in which the conductors run freely at a distance from each other is so far not possible, but desirable. They are multi-core twisted cables known in which the insulation between the twisted at a distance from each other individual conductors and the insulating jacket surrounding the line from a uniform coherent insulating material is formed. With these lines is the outer one Insulating jacket at individual points with incisions running inwards provided, and the twisting is carried out only after the insulation has been made. This results in harmful stress on the insulation of the line.
Gemäß der Erfindung wird dieser Nachteil vermieten und die Herstellung wesentlich dadurch vereinfacht, daß die Verdrallung der Leiter innerhalb der Spritzmaschine erfolgt, welche auch die Isolierung der einzelnen Leiter gleichzeitig mit der Herstellung des Isoliermantels bewirkt. Vorteilhafterweise werden die zu verdrallenden Leiter parallel auf einem Dorn, der in das Mundstück der Spritzmaschine hineinragt, aufgewickelt und von diesem während des Spritzvorganges abgezogen. Zweckmäßig ist es, hierbei einen rotierenden, insbesondere hohl ausgebildeten Dorn zu verwenden, der an der Einlaufseite, an welcher die zu verdrallenden Leiter parallel aufgewickelt werden, einen größeren Durchmesser aufweist als an der Seite des Spritzmundstückes. Je nach dem Dorndurchmesser und dem späteren Abstand der abgezogenen verdrallten Leiter kann die Drallänge geändert werden. Auf diese Weise ist es möglich, bei geeigneter Konstruktion der Spritzmaschine mehradrige verdrallte Leitungen in einem Arbeitsgang zu umspritzen. According to the invention, this disadvantage is rented and the manufacture significantly simplified by the fact that the twisting of the conductors within the injection molding machine takes place, which also the insulation of the individual conductors at the same time with the manufacture of the insulating jacket. The conductors to be twisted are advantageously wound in parallel on a mandrel that protrudes into the mouthpiece of the injection molding machine and deducted from this during the injection process. It is useful here to use a rotating, in particular hollow mandrel, which is attached to the Inlet side on which the conductors to be twisted are wound up in parallel, has a larger diameter than on the side of the nozzle. Depending on the mandrel diameter and the subsequent distance between the withdrawn twisted conductors the twist length can be changed. In this way it is possible with appropriate Construction of the injection molding machine multi-core twisted cables in one operation to encapsulate.
Die Verdrallung der einzelnen Leiter kann auch auf einem isolierenden Kern vorgenommen werden, der durch den Hohldorn in die Spritzmaschine einläuft.The twisting of the individual conductors can also be on an insulating Core are made, which runs through the hollow mandrel into the injection molding machine.
Für den isolierenden Kern kann zweckmäßig ein leicht verformbarer Werkstoff verwendet werden. Es kann dieser Kern auch während des Umspritzens selbst gebildet werden. Auf diese Weise ist es möglich, stets einen gleichen Abstand der Leiter voneinander nach der Verdrallung zu erreichen.An easily deformable one can expediently be used for the insulating core Material are used. This core can also be used during the overmolding itself are formed. In this way it is possible to always keep the same distance Head to reach each other after twisting.
In den Fig. 1 und 2 ist die Erfindung schematisch dargestellt und näher erläutert. In der nicht näher dargestellten Spritzmaschine mit dem Spritzkopf 1 ist ein rotierender Hohldorn 2 angeordnet, auf welchen die zu verdrallenden Leiter 3 und 4 parallel aufgewickelt werden. Der Dorn 2 weist in Richtung auf den Spritzkopf 1 einen Konus 5 auf, über welchen die zu ver- drallenden Leiter 3 und 4 durch den Spritzkopf hindurchgezogen werden. Die verdrallten Leiter 3 und 4 werden mit Isolierstoff 6 umspritzt, wobei gleichzeitig auch durch den Dorn 2 Isolierstoff hindurchgepreßt wird, welcher die verdrallten Leiter im Abstand voneinander hält. Durch den hohl ausgebildeten Dorn 2 kann auch ein isolierender Kern einlaufen, so daß die abgezogenen verdrallten Leiter stets einen gleichen Abstand voneinander haben. Der Kern kann aus dem gleichen Werkstoff wie der Mantel oder aus einem anderen Werkstoff gebildet sein. In Figs. 1 and 2, the invention is shown schematically and explained in more detail. In the injection molding machine, not shown, with the injection head 1 a rotating hollow mandrel 2 is arranged on which the conductor to be twisted 3 and 4 are wound up in parallel. The mandrel 2 points in the direction of the extrusion head 1 a cone 5, over which the to be twisting conductors 3 and 4 through the The spray head can be pulled through. The twisted conductors 3 and 4 are covered with insulating material 6 encapsulated, with insulation material also being pressed through the mandrel 2 at the same time which keeps the twisted conductors at a distance from each other. Through the hollow formed mandrel 2 can also run into an insulating core, so that the withdrawn twisted conductors always have the same distance from each other. The core can formed from the same material as the jacket or from a different material be.
