Description

Die Erfindung liegt auf dem Gebiet der Montagetechnik für Starkstromkabel und ist bei der konstruktiven Ausgestaltung einer Preßhülse anzuwenden, mit der der Leiter eines Mittel-oder Hochspannungskabels in einer vorgefertigten Kabeigarnitur steckbar verbunden wird.The invention is in the field of assembly technology for power cables and is to be used in the structural design of a compression sleeve with which the conductor of a medium or high voltage cable is connected in a prefabricated cable set.

Um die Montage von Garnituren an Mittel- und Hochspannungskabeln zu vereinfachen, ist man bestrebt, vorgefertigte Bauteile einzusetzen. Dies gilt nicht nur für den das Kabelende oder die Kabeiverbindungsstelle umgebenden Isolierkörper, sondern auch für die Herstellung der Leiterverbindung.In order to simplify the assembly of sets on medium and high voltage cables, efforts are being made to use prefabricated components. This applies not only to the insulating body surrounding the cable end or the cable connection point, but also to the manufacture of the conductor connection.

Bei einer bekannten Verbindungsmuffe für kunststoffisolierte, geschirmte Starkstromkabel erfolgt die Verbindung der Leiter mit Hilfe von Preßhülsen, die mit einem Steckerteil versehen sind. Dabei ist der Außendurchmesser der einzelnen Preßhülse kleiner als der Außendurchmesser der Aderisolierung (US-A-3 571 783). Dies setzt bei den bekannten Preßhülsen aus Kupfer oder Aluminium entweder einen kleinen Leiterquerschnitt oder eine große Wandstärke der Isolierung voraus. Bei größeren Leiterquerschnitten und geringeren Isolierwandstärken sind diese Durchmesserverhältnisse jedoch nicht gegeben, da Preßhülsen aus Kupfer oder Aluminium mit Rücksicht auf die erforderlichen Kontaktkräfte eine bestimmte Wandstärke aufweisen müssen. Diese Wandstärke ist bei Preßhülsen aus Aluminium wegen der gegenüber Kupfer geringeren Festigkeit größer als bei Preßhülsen aus Kupfer.In a known connecting sleeve for plastic-insulated, shielded power cables, the connection of the conductors is carried out with the aid of compression sleeves which are provided with a plug part. The outer diameter of the individual compression sleeve is smaller than the outer diameter of the wire insulation (US-A-3 571 783). In the known compression sleeves made of copper or aluminum, this requires either a small conductor cross section or a large wall thickness of the insulation. In the case of larger conductor cross sections and smaller insulating wall thicknesses, these diameter ratios do not exist, however, since compression sleeves made of copper or aluminum have to have a certain wall thickness in consideration of the required contact forces. This wall thickness is greater in aluminum compression sleeves because of the lower strength than copper than in copper compression sleeves.

Die erwähnten Durchmesserverhältnisse sind besonders bei vorgefertigten Garnituren zu beachten, deren Isolierkörper aus einem elastischen Material besteht und die eine Bohrung zur Aufnahme der Kabelader aufweisen, wobei der Durchmesser dieser Bohrung kleiner als der Aderdurchmesser ist. Bei einer bekannten Garnitur dieser Art, die für eine Kabelader mit kleinem Leiterquerschnitt vorgesehen ist, dient zur Leiterverbindung eine Preßhülse aus Aluminium, die mit einem Kontaktteil aus Kupfer verschweißt ist. Das Kontaktteil ist zur Aufnahme eines Kontaktstiftes mit einem Gewinde versehen (US-A-3 876 280).The diameter ratios mentioned are particularly important for prefabricated sets, the insulating body of which is made of an elastic material and which have a bore for receiving the cable core, the diameter of this bore being smaller than the core diameter. In a known set of this type, which is provided for a cable core with a small conductor cross section, a compression sleeve made of aluminum is used for the conductor connection, which is welded to a contact part made of copper. The contact part is provided with a thread for receiving a contact pin (US-A-3 876 280).

Zur Verbindung von blanken elektrischen Leitern, die verhältnismäßig großen Zugbeanspruchungen unterworfen sind, ist an sich eine Preßhülse bekannt, deren eigentliches Preßteil aus Stahl besteht und die zur elektrischen Kontaktierung der Leiter in der Mitte mit einer Kupferhülse und zur Herstellung einer guten mechanischen Verbindung beidseitig angrenzend mit zwei Spannhülsen ausgekleidet ist (DE-B-1 072671). Weiterhin ist für Schaltadern bereits eine Preßhülse vorgeschlagen worden, die mit einem Steckerteil versehen ist und deren Preßteil aus einer inneren, weichen Kupferhülse und einer äußeren Stahlhülse besteht (EP-A-18 863 nach Art. 54(3), in Bezug auf Frankreich).For the connection of bare electrical conductors which are subject to relatively large tensile stresses, a compression sleeve is known per se, the actual pressing part of which is made of steel and which is used for electrical contacting of the conductors in the middle with a copper sleeve and for establishing a good mechanical connection on both sides with two clamping sleeves is lined (DE-B-1 072671). Furthermore, a press sleeve has already been proposed for switching wires, which is provided with a plug part and whose press part consists of an inner, soft copper sleeve and an outer steel sleeve (EP-A-18 863 according to Art. 54 (3), in relation to France) .

Ausgehend von einer Preßhülse mit den Merkmalen des Oberbegriffes des Anspruchs 1 liegt der Erfindung die Aufgabe zugrunde, durch eine konstruktive Ausgestaltung der Preßhülse sicherzustellen, daß für Kabeigarnituren mit einem elastischen Isolierkörper auch bei großen Leiterquerschnitten der äußere Durchmesser der Preßhülse kleiner als der äußere Durchmesser der Kabelader ist.Starting from a press sleeve with the features of the preamble of claim 1, the invention has for its object to ensure by a structural design of the press sleeve that for cable sets with an elastic insulating body, even with large conductor cross-sections, the outer diameter of the press sleeve smaller than the outer diameter of the cable core is.

Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, daß die mit dem Steckerteil verbundene Preßhülse aus einer inneren Teilhülse aus Kupfer oder Aluminium und einer äußeren Teilhülse aus Stahl besteht.To achieve this object it is provided according to the invention that the press sleeve connected to the plug part consists of an inner partial sleeve made of copper or aluminum and an outer partial sleeve made of steel.

Mit Hilfe dieser Ausgestaltung wird also erreicht, daß der äußere Durchmesser der Preßhülse auch bei größeren Leiterquerschnitten kleiner als der äußere Durchmesser der Aderisolierung ist. Die beiden Teilhülsen der zweischichtig ausgebildeten Preßhülse übernehmen dann einerseits im wesentlichen die mechanische Funktion der Preßhülse, andererseits im wesentlichen die elektrische Funktion.With the help of this configuration it is thus achieved that the outer diameter of the compression sleeve is smaller than the outer diameter of the wire insulation even with larger conductor cross sections. The two partial sleeves of the two-layer press sleeve then take on the one hand essentially the mechanical function of the press sleeve, on the other hand essentially the electrical function.

Die zweischichtige Preßhülse kann auf zwei Wegen hergestellt werden. Man kann die einzelnen Schichten als selbständige Bauteile herstellen und sie aufeinander aufziehen. Man kann aber auch zweischichtiges Material verwenden, beispielsweise plattiertes, gerolltes oder geschweißtes Bandmaterial. Um die Preßkräfte beim Verformen der Hülse zu reduzieren, können im übrigen in der äußeren Hülsenschicht (Druckhülse) Ausnehmungen vorgesehen sein. Beim Verpressen der Preßhülse kann dann das weiche Kontaktierungsmaterial der inneren Hülsenschicht unter dem Druck der Werkzeugbakken in die Ausnehmungen der äußeren Hülsenschicht hineinfließen und auf diese Weise noch die gesamte Preßhülse versteifen.The two-layer compression sleeve can be manufactured in two ways. The individual layers can be produced as independent components and put on top of one another. But you can also use two-layer material, for example clad, rolled or welded strip material. In order to reduce the pressing forces when the sleeve is deformed, recesses can also be provided in the outer sleeve layer (pressure sleeve). When pressing the compression sleeve, the soft contacting material of the inner sleeve layer can then flow into the recesses of the outer sleeve layer under the pressure of the tool jaws and in this way still stiffen the entire compression sleeve.

Beim Verpressen der Preßhülse mittels Sechskantpressung entstehen scharfe Kanten, die die Innenwandung einer aufschiebbaren Garnitur verletzen können. Um eine solche Verletzung zu vermeiden, empfiehlt es sich, die Preßhülse nach dem Verpressen durch einen Schrumpfschlauch abzudecken.When pressing the compression sleeve by means of hexagonal pressing, sharp edges are created which can damage the inner wall of a slide-on set. In order to avoid such an injury, it is advisable to cover the compression sleeve with a shrink tube after pressing.

Zwei Ausführungsbeispiele der neuen Preßhülse sind in den Figuren 1 und 2 dargestellt.Two embodiments of the new press sleeve are shown in Figures 1 and 2.

Fig. 1 zeigt eine Preßhülse 11, die mit einem Steckerteil 10. aus Kupfer versehen ist. Die Preßhülse selbst besteht aus einer inneren Teilhülse 12 aus Aluminium und einer äußeren Teilhülse 13 aus Stahl. Preßhülse 11 und Steckerteil 10 sind durch Reibschweißen miteinanderverbunden.Fig. 1 shows a press sleeve 11 which is provided with a plug part 10 made of copper. The compression sleeve itself consists of an inner partial sleeve 12 made of aluminum and an outer partial sleeve 13 made of steel. Press sleeve 11 and plug part 10 are connected to one another by friction welding.

Gemäß Fig. 2 ist die zweischichtige Preßhülse 11 durch Kaltpreßschweißen mit einem Steckerteil 20 in Form einer Steckbuchse verbunden. Die Preßhülse 11 besteht ebenfalls aus einer inneren Teilhülse 12 aus Aluminium und einer darauf aufgezogenen äußeren Teilhülse 13 aus Stahl.2, the two-layer press sleeve 11 is connected by cold pressure welding to a plug part 20 in the form of a socket. The compression sleeve 11 also consists of an inner partial sleeve 12 made of aluminum and an outer partial sleeve 13 mounted thereon made of steel.
