Description

Gegenstand der Erfindung ist ein Kabelschuh für. elektrische Leiter mit einer Zwinge, die auf das abisolierte Leiterende gepreßt wird und deren Innenfläche sich mit dem Leiter verzahnt, wodurch eine mechanisch feste und korrosionsfreie elektrische Verbindung zwischen dem Leiter und dem Kabelschuh ermöglicht wird.The invention relates to a cable lug for. Electrical conductors with a ferrule that is pressed onto the stripped end of the conductor and its inner surface interlocks with the conductor, creating a mechanically strong and corrosion-free electrical connection is made possible between the conductor and the cable lug.
Es sind Kabelschuhe bekannt, bei denen die Innenflächen der Zwinge V-förmige Längsnuten aufweisen. Kabelschuhe mit solchen Kerbverzahnungen neigen jedoch beim Einpressen und bei übermäßiger Längung zum Reißen. Außerdem ist der anwendbare Drahtstärkenbereich begrenzt, da der Draht von der Zwinge gefaßt werden muß, bevor die Einpressung zu weit fortgeschritten ist.Cable lugs are known in which the inner surfaces of the clamp have V-shaped longitudinal grooves. However, cable lugs with such serrations tend to elongate when they are pressed in and when they are excessively elongated to tear. In addition, the wire size range that can be used is limited because the wire is removed from the ferrule must be grasped before the injection is too far advanced.
Die Erfindung bezweckt unter gleichzeitiger Verbesserung der Fertigungsbedingungen und Betriebseigenschaften die Beseitigung der genannten Nachteile. Die Erfindung besteht darin, daß die Innenfläche der Kabelschuhzwinge mit örtlich begrenzten Vertiefungen versehen ist, die scharfe obere Umfangskanten und sanft gerundete Bodenflächen aufweisen. Die Vertiefungen sind vorzugsweise derart versetzt angeordnet, daß die Verbindungslinien zwischen nächstliegenden Vertiefungen schräg zu der Zwingenlängsachse und quer zu den Beanspruchungslinien verlaufen, die durch die Ausbildung von Längssicken beim Einpressen entstehen.The invention aims to improve the manufacturing conditions and operating properties at the same time the elimination of the disadvantages mentioned. The invention consists in that the inner surface the cable lug clamp is provided with localized depressions, the sharp upper peripheral edges and have gently rounded bottom surfaces. The depressions are preferably offset in this way arranged that the connecting lines between the closest depressions obliquely to the clamp longitudinal axis and run transversely to the lines of stress caused by the formation of longitudinal beads arise during pressing.

Fig. 2 veranschaulicht einen mit dem Kabel verbundenen Kabelschuh nach dem Einpressen;Fig. 2 illustrates a cable lug connected to the cable after being pressed in;
Fig. 3 zeigt einen Querschnitt nach der Linie 3-3 der Fig. 2.FIG. 3 shows a cross section along the line 3-3 in FIG. 2.
Der Rohling nach Fig. 1 ist mit Vertiefungen 21 versehen, die beispielsweise derart symmetrisch angeordnet sind, daß die Verbindungslinien zwischen nächstliegenden Vertiefungen jeweils schräg zur Zwingenlänge verlaufen. Die Vertiefungen weisen scharfe obere Umfangskanten und sanft gerundete Bodenflächen auf. Die Vertiefungen 21, die angenähert halbkugelförmig dargestellt sind, können aber auch geringfügig konisch. U-förmig oder rillenartig ausgebildet sein. Auch brauchen sich diese Vertiefungen nicht über die gesamte Innenfläche der Zwinge zu erstrecken, sondern können auf bestimmte Flächenbereiche beschränkt sein.The blank according to FIG. 1 is provided with depressions 21 which, for example, are arranged symmetrically in this way are that the connecting lines between the closest depressions are inclined to Clamp length run. The depressions have sharp upper peripheral edges and gently rounded ones Floor areas on. The recesses 21, which are shown approximately hemispherical, but can also slightly conical. Be U-shaped or groove-like. These deepenings also need each other not to extend over the entire inner surface of the clamp, but can on certain surface areas be limited.
Die Zwinge 24 wird in bekannter Weise vorgeformt, auf das abisolierte Drahtende geschoben und mit Stempel und Matrize so eingepreßt, daß gemäß Fig. 2 in Abstand von den äußeren Querkanten der Zwinge symmetrisch zur Stoßfuge 34 zwei Längssicken 30' mit abgerundeten Schmalkanten und Bodenflächen ausgebildet werden. Wie man aus dem Querschnitt nachThe clamp 24 is preformed in a known manner, pushed onto the stripped wire end and with it Stamp and die pressed in so that, as shown in FIG. 2, at a distance from the outer transverse edges of the clamp symmetrically to the butt joint 34 two longitudinal beads 30 'formed with rounded narrow edges and bottom surfaces will.

Fig. 3 erkennt, findet unter Bildung von Falzen 36 eine feste Einpressung des Leiters statt. Das durch den Einpreßdruck erzielte Fließen des Leiters führt die Bildung von Ausstülpungen des Leiters herbei, die zusammen mit den Vertiefungen 21 der Zwinge eine starke Verriegelungswirkung ausüben (Fig. 3). In diesem Zusammenhang kommt den oberen scharfen Umfangskanten der Vertiefungen besondere Bedeutung zu. Da infolge der neuartigen Form und Anordnung der Vertiefungen 21 die Bildung von Linien konzentrierter Beanspruchung vermieden wird, kann ein Reißen der Zwingenwandung nicht mehr auftreten. Es ist vorteilhaft, die Stoßfuge 34 hart zu löten und den Kabelschuh zu glühen.3 recognizes that the conductor is pressed in firmly with the formation of folds 36. That through The flow of the conductor achieved by the injection pressure leads to the formation of protuberances in the conductor which together with the depressions 21 of the ferrule exert a strong locking effect (FIG. 3). In In this connection, the upper sharp peripheral edges of the depressions are of particular importance to. Because of the novel shape and arrangement of the depressions 21 the formation of lines concentrated stress is avoided, tearing of the clamp wall can no longer occur. It is advantageous to hard solder the butt joint 34 and to anneal the cable lug.
