Abstract

The connector has a plug (20) at one end and a crimp-fit sleeve (21) at the other. The crimp sleeve has two or more layers to ensure that the outer diameter of the sleeve is also less than the diameter of the wire or conductor being connected. The inner layer (22) is made of copper or aluminium and acts as current conductor whilst one outer layer (23) is made of steel and ensures that the inner layer maintains contact with the wire after crimping. The combination of plug and crimp sleeve reduces the work involved in attaching the plug to the cable's wire or conductor. The connector couples cables to cable fittings simplifying the amount of work required in connecting such fittings.

Description

Kabelgarnitur mit einem SteckelementCable set with a plug-in element

Die Erfindung bezieht sich auf eine Kabelgarnitur mit einem Steckelement, das aus einem Steckerteil und einem Verbindungselement besteht.The invention relates to a cable fitting with a plug-in element, which consists of a plug part and a connecting element.

Um die Garniturenmontage von Hochspannungskabeln zu vereinfachen, ist man bemüht, Steckelemente einzusetzen.To simplify the assembly of high-voltage cables, one tries to use plug-in elements.

Die aus der Niederspannungstechnik bekannten und bewährten Steckelemente müssen dabei mit dem Kabelleiter verbunden werden.The well-known and proven plug-in elements from low-voltage technology must be connected to the cable ladder.

Bekannt sind Steckelemente, die durch Schrauben oder Löten mit dem Leiter verbunden werden. Grundsätzlich konnen auch für Hochspannungskabel Löt- und Schraubverbindungen eingesetzt werden, Jedoch haben sich Preßverbindungen wegen ihrer einfachen und problemlosen Montage durchgesetzt. Dies trifft besonders für Kabel mit Aluminiuileitern zu.Plug-in elements are known, which are screwed or soldered to the Conductors are connected. Basically you can also use soldering and soldering for high-voltage cables Screw connections are used, However, press connections have because of their simple and problem-free assembly prevailed. This is especially true for Cable with aluminum conductors too.

Der Erfindung liegt daher die Aufgabe zugrunde, geeignet ausgebildete Steckelemente für Garnituren zu schaffen.The invention is therefore based on the object of being suitable trained To create plug-in elements for sets.

Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, daß das Steckerteil mit einer PreßhUlse zu einem Steckelement kombiniert ist.To solve this problem it is proposed according to the invention, that the plug part is combined with a press sleeve to form a plug-in element.

Diese hinsichtlich der Montage vorteilhafte Kombination kann man entweder dadurch realisieren, daß man die Preßhülse mehrschichtig ausbildet, oder dadurch, daß sie aus Stahl besteht, die mit einem Ueberzug aus dem Material des Steckerteiles versehen ist. Das Steckerteil des Steckelementes besteht dabei stets aus einem elektrisch gut leitenden Material, z. B. Kupfer, während die Preßhülse aus einem Material besteht, das einen guten Kontakt zum Jeweiligen Leiter gewährleistet. Fur Kupferleiter ist die Preßhülse vorzugsweise aus Kupfer bzw. mit Kupfer überzogen, für Aluminiumleiter aus Aluminium bzw. mit Aluminium überzogen.This combination, which is advantageous in terms of assembly, can be either realize by making the compression sleeve multilayered, or by that it consists of steel with a coating made of the material of the plug part is provided. The plug part of the plug element always consists of an electrical one highly conductive material, e.g. B. copper, while the compression sleeve is made of a material, that ensures good contact with the respective leader. For copper conductor is the compression sleeve preferably made of copper or coated with copper, for aluminum conductors made of aluminum or coated with aluminum.

Sofern es sich um Teile unterschiedlicher Werkstoffe handelt, wird man das Steckerteil und die Preßhilise stoffschlüssig, z. B. mittels einer Reib- oder Kaltpreßschweißung, miteinander verbinden.If the parts are made of different materials, you the plug part and the Preßhilise cohesively, z. B. by means of a friction or cold pressure welding.

Die Preßhülsen aus Kupfer und Aluminium müssen, um die erforderlichen Kontaktkräfte auf dem Leiter zu erhalten, eine bestimmte Wandstärke haben. Bei Aluminluileitern ist diese wegen der gegenüber Kupfer geringeren Festigkeit größer als bei Kupferhülsen. In bestimmten Anendungsfällen, insbesondere bei großen Leiterquerschnitten, ist eine geringere Wandstärke erwünscht, weil dadurch z. B. einfachere Garnituren möglich sind. Eine solche Ausfühng ist in der älteren Anmeldung (P 29 31 642.5) als doppelwandige Konstruktion vorgeschlagen worden. Da- bei wird Uber eine im Durchmesser stark reduzierte Kupfer oder Aluminiumleiterhülse eine Druckhülse aus Stahl geschoben.The ferrules made of copper and aluminum have to meet the required To get contact forces on the conductor, have a certain wall thickness. With aluminum conductors this is greater than with copper sleeves because of the lower strength compared to copper. In certain application cases, especially with large conductor cross-sections, a smaller wall thickness is desirable because this z. B. simpler sets possible are. Such a version is in the older application (P 29 31 642.5) as a double-walled Construction has been proposed. There- at will be about one in diameter greatly reduced copper or aluminum conductor sleeve, a steel compression sleeve is pushed.

Soll ein Steckerteil aus Kupfer oder Aluminium mit einer Preßhülse aus Stahl vorzugsweise stoffschlüssig verbunden und dazu die Stahlpreßhülse mit einem Uberzug aus dem Material des Steckerteiles versehen werden, wird man dies in erster Linie durch ein galvanisches Verfahren bewirken. Für Kupferleiter wird vorgeschlagen, die Preßhülse zu versilbern, für Aluminiumleiter die Preßhülse zu verzinnen.Should a plug part made of copper or aluminum with a compression sleeve made of steel, preferably cohesively connected and for this purpose the steel compression sleeve with be provided with a cover made of the material of the plug part, one will primarily through a galvanic process. For copper conductors, proposed to silver the compression sleeve, the compression sleeve for aluminum conductors tin.

Beim Verpressen der Preßhülsen-Steckelemente mit Sechskantpressung entstehen scharfe Kanten, die die Innenwandung einer aufschiebbaren Garnitur verletzen können.When pressing the compression sleeve plug-in elements with hexagonal pressing there are sharp edges that damage the inner wall of a push-fit set can.

Um eine solche Verletzung zu vermeiden, kann man die Preßhülse nach dem Verpressen durch einen Schrumpfschlauch abdecken.In order to avoid such an injury, the compression sleeve can be adjusted cover with shrink tubing before pressing.

Die Erfindung wird anhand der in der Zeichnung dargestellten Ausführungsbeispiele im einzelnen erläutert.The invention is based on the exemplary embodiments shown in the drawing explained in detail.
