Description

Verfahren zum Herstellen von isolierten Leitungen, insbesondere sogenannten Stegleitungen. durch Umspritzen elektrischer Leiter mit thermoplastischen Isolierstoffen, Gummi oder gummiähnlichen Isolierstoffen Das Herstellen isolierter Leitungen durch das gleichzeitige Umspritzen einer größeren Anzahl elektrischer Leiter mit Hilfe eines einzigen Spritzkopfes ist wegen der Unterschiede des Druckes und der Stofförderung des Spritzgutes in und zu den einzelnen Spritzdüsen mit besonderen Schwierigkeiten verbunden. Es ist deshalb vorgeschlagen worden, die Spritzdüsen konzentrisch zu einem gemeinsamen Preßkanal anzuordnen, durch den das Spritzgut zugeführt wird. Auf diese Weise werden in den Spritzdüsen die gleichen Bedingungen bezüglich des Druckes und der Stofförderung des zu verarbeitenden Spritzgutes für alle Leitungen erzielt.Method for producing insulated lines, in particular so-called Ribbon cables. by encapsulating electrical conductors with thermoplastic insulating materials, Rubber or rubber-like insulating materials The production of insulated cables through the simultaneous encapsulation of a large number of electrical conductors with the aid a single spray head is due to the differences in pressure and material feed the spray material in and to the individual spray nozzles with particular difficulties tied together. It has therefore been proposed that the spray nozzles be concentric to arrange a common compression channel through which the spray material is fed. In this way, the same conditions with respect to the Pressure and the material delivery of the spray material to be processed for all lines achieved.

Das Verfahren gemäß der Erfindung stellt eine vorteilhafte Weiterbildung des obenerwähnten Vorschlages dar und besteht darin, daß eine Vielzahl ringförmig angeordneter Leiter gleichzeitig derart umspritzt wird, daß ein geschlossener Schlauch entsteht, und daß nachträglich die einzelnen Leitungen in geeigneter Weise von diesem Schlauch abgetrennt werden. The method according to the invention represents an advantageous further development of the above proposal and is that a plurality of ring-shaped arranged conductor is overmolded at the same time so that a closed hose arises, and that subsequently the individual lines in a suitable manner from this Hose are disconnected.

Bei Verwendung vulkanisierbarer Isolierstoffe kann der durch das Spritzen gebildete Schlauch in Längsrichtung aufgeschnitten und als Band vulkanisiert werden. Durch diese Maßnahme wird die Vulkanisierung von Gummileitungen wesentlich vereinfacht.When using vulcanizable insulating materials, the spraying formed tube can be cut in the longitudinal direction and vulcanized as a tape. This measure considerably simplifies the vulcanization of rubber lines.

Das Verfahren gemäß der Erfindung wird beispielsweise an Hand der Abbildungen der Zeichnung noch näher erläutert. The method according to the invention is exemplified by means of Illustrations of the drawing explained in more detail.

Die Abb. I und 2 stellen ein Spritzwerkzeug dar, mit dessen Hilfe Doppelleitungen gespritzt werden können, die je aus zwei Einzeladern bestehen, welche durch einen Isolierstoffsteg miteinander verbunden sind. Das Spritzwerkzeug besteht im wesentlichen aus dem Dorn I, in dem Kanäle zur Durchführung der Leiter angeordnet sind und auf dem überdies noch zur besseren Führung der Leiter der Führungsring 2 befestigt ist, und der Matrize 3. Zur Ausübung des Verfahrens gemäß der Erfindung werden die ringförmig angeordneten Leiter 4 mit Hilfe dieses Werkzeuges mit thermoplastischen Isolierstoffen bzw. Gummi oder gummiähnlichen Stoffen umspritzt, so daß ein geschlossener Schlauch entsteht. Danach wird dieser geschlossene Schlauch in Längsrichtung aufgeschnitten und das dadurch entstehende Band gegebenenfalls vulkanisiert. Schließlich werden die einzelnen Leitungen von dem Band abgetrennt, so daß mit einem Isolierstoffsteg ausgestattete Doppelleitungtn entstehen, die den in Abb. 3 dargestellten ouerschnitt aufweisen. Figs. I and 2 represent an injection molding tool with the help of which Double lines can be injected, each consisting of two single wires, which through an insulating bar are connected to each other. The injection mold consists essentially of the mandrel I, in the channels for the implementation of the ladder are arranged and on which, moreover, the guide ring for better guidance of the head 2 is attached, and the die 3. To practice the method according to the invention the ring-shaped conductor 4 with the help of this tool with thermoplastic Insulating materials or rubber or rubber-like materials overmolded, so that a closed Hose arises. Then this closed tube is cut open in the longitudinal direction and the resulting tape is optionally vulcanized. Eventually be the individual lines separated from the tape, so that with an insulating web Equipped double lines are created which have the cross-section shown in Fig. 3 exhibit.

Das Verfahren gemäß der Erfindung ist nicht auf das erwähnte Ausführungsbeispiel beschränkt, es kann vielmehr auch zlr Herstellung von isolierten Leitungen angewendet werden, die nur eine einzige Ader aufweisen. The method according to the invention is not limited to the mentioned embodiment limited, it can also be used for the production of insulated cables that only have a single core.

Bei Verwendung vulkanisierbarer Isolierstoffe können die Leitungen auch unmittelbar nach dem Spritzen de; Schlauches abgetrennt und einzeln vulkanisiert werden.When using vulcanizable insulating materials, the cables also immediately after spraying de; Hose separated and vulcanized individually will.
