Die Erfindung betrifft einen Kabelschuh mit einem Hülsenbereich mit einer Öffnung zur Aufnahme eines Rundkabels, wobei der Hülsenbereich eine ovale oder längliche Außenform aufweist.The invention relates to a cable lug with a sleeve region with an opening for receiving a round cable, wherein the sleeve region has an oval or elongated outer shape.
Derartige Kabelschuhe werden beispielsweise bei Seilhängem beim Bau und der Instandsetzung von Oberleitungen der Bahn verwendet, die zur Ableitung von Kurzschlussströmen dienen.
10Such cable lugs are used, for example, in cable hangers during the construction and repair of overhead railway lines, which serve to divert short-circuit currents.

Der Kabelschuh dient dabei der Aufnahme des Endes genau eines Kupfer-Rundkabels, das mit dem Hülsenbereich des Kabelschuhs verpresst wird.The cable lug is used to hold the end of exactly one round copper cable, which is pressed into the sleeve area of the cable lug.
Die üblicherweise verwendeten Verarbeitungswerkzeuge nehmen in der Regel lediglich ovale Verbindungen auf, mit denen zwei Kupferkabel oder Kupferleiter verpresst werden. Eine sichere Verbindung des herkömmlichen Kabelschuhs mit ovalem Hülsenbereich und einem einzigen Rundleiter ist daher problematisch.The processing tools commonly used generally only accommodate oval connections with which two copper cables or copper conductors are crimped. A secure connection of the conventional cable lug with an oval sleeve area and a single round conductor is therefore problematic.
Um dennoch eine Befestigung zu gewährleisten, muss herkömmlicherweise ein runder Kupferstift zusätzlich zu dem Rundleiter in den Hülsenbereich eingeschoben und zusammen mit dem Kupferleiter verpresst werden.In order to ensure a secure fastening, a round copper pin must be inserted into the sleeve area in addition to the round conductor and pressed together with the copper conductor.
Die zusätzliche Verwendung des Kupferstiftes ist jedoch aufwendig. Weiterhin sind derartige Zusatzteile oftmals vor Ort nicht verfügbar bzw. gehen aufgrund ihrer kleinen Größe verloren. In diesem Fall schneidet der Anwender oftmals entweder ein Stück Kupferleiter ab und steckt es zusätzlich zu dem Rundkabel in den Kabelschuh, um diese zu vorpressen. Im ungünstigsten Fall wird der ovale Kabelschuh mit nur einem Rundleiter verpresst. Beide Methoden führen zu Unsicherheiten und Störungen des Betriebs. Außerdem besteht Verletzungsgefahr an den scharfen Kanten des abgeschnittenen Leiters.However, the additional use of the copper pin is complex. Furthermore, such additional parts are often not available on site or are lost due to their small size. In this case, the user often either cuts off a piece of copper conductor and inserts it into the cable lug in addition to the round cable in order to pre-press it. In the worst case, the oval cable lug is pressed with only one round conductor. Both methods lead to uncertainties and disruptions in operation. There is also a risk of injury from the sharp edges of the cut conductor.

sichere, schnelle und einfache Befestigung des Rundkabels in dem Kabelschuh zu gewährleisten.to ensure safe, quick and easy fastening of the round cable in the cable lug.
Diese Aufgabe wird bei dem eingangs genannten Kabelschuh erfindungsgemäß gelöst, indem in dem Hülsenbereich zumindest an einer Stirnwand eine runde Bohrung ausgebildet ist.This object is achieved according to the invention in the cable lug mentioned at the outset in that a round bore is formed in the sleeve area at least on one end wall.
Erfindungsgemäß wird somit auf überraschend einfache Weise eine einfache und sichere Aufnahme eines einzigen Kupfer-Rundkabels in dem Hülsenbereich des Kabelschuhs ermöglicht. Der Erfindung liegt hierbei die Erkenntnis zugrunde, dass die bei dem herkömmlichen ovalen Kabelschuh vorgesehene Aufnahme eines Kabels und eines Sicherungsstiftes, die zu den o.g. Problemen führt, durch Ausbildung einer einzigen runden Bohrung umgangen werden kann.According to the invention, a single round copper cable can be accommodated in the sleeve area of the cable lug in a surprisingly simple manner. The invention is based on the knowledge that the need to accommodate a cable and a locking pin in the conventional oval cable lug, which leads to the problems mentioned above, can be avoided by creating a single round hole.
Um die Aufnahme des Rundkabels zu erleichtern, kann die Bohrung in der Stirnwand sich nach innen hin konisch verjüngen, z. B. mit einem Kegel-Öffnungswinkel von ca. 60°.To facilitate the insertion of the round cable, the hole in the front wall can taper conically towards the inside, e.g. with a conical opening angle of approx. 60°.

Ein Kabelschuh weist einen Hülsenbereich 1 auf, der gegenüber einem abgeflachten Endbereich 2 um z. B. 30° abgewinkelt ist. In dem abgeflachten Endbereich 2 ist in an sich bekannter Weise eine Bohrung 5 vorgesehen.A cable lug has a sleeve region 1 which is angled by, for example, 30° relative to a flattened end region 2. A bore 5 is provided in the flattened end region 2 in a manner known per se.
Der Hülsenbereich 1 weist in bekannter Weise eine ovale oder längliche Außenform auf. An einem vorderen Ende des Hülsenbereiches ist eine Stirnwand 4 ausgebildet, in der wiederum eine runde Bohrung 3 ausgebildet ist.The sleeve region 1 has an oval or elongated outer shape in a known manner. At a front end of the sleeve region, an end wall 4 is formed, in which a round bore 3 is formed.
Gernäß Figur 1 weist die Bohrung 3 nach innen eine konische Verjüngung mit einem Öffnungswinkel von &zgr;. &Bgr;. &agr; = 60° auf.According to Figure 1, the bore 3 has a conical taper towards the inside with an opening angle of ζ. β. α = 60°.
Der erfindungsgemäße Kabelschuh ist vorteilhafterweise aus Kupfer bzw. einer Kupferlegierung hergestellt. Der große Durchmesser der Ovalform oder länglichen Form kann beispielsweise 10 mm bis 11 mm, z. B. 10,7 mm, der kleine Durchmesser z. B. 7 mm betragen. Die Bohrung kann an ihrem weiteren Ende z. B. einen Durchmesser von 6 mm und an ihrem inneren, verjüngten Ende z. B. einen Durchmesser von 5,1 mm bis 5,3 mm aufweisen.The cable lug according to the invention is advantageously made of copper or a copper alloy. The large diameter of the oval shape or elongated shape can be, for example, 10 mm to 11 mm, e.g. 10.7 mm, and the small diameter can be, for example, 7 mm. The bore can have, for example, a diameter of 6 mm at its wider end and, for example, a diameter of 5.1 mm to 5.3 mm at its inner, tapered end.
