Description

Als Klemmverbindungen für gespannte elektrische Leitungen, Drahtzüge usw. sind hauptsächlich Muffenverbinder und Hülsenverbinder bekannt geworden. Während die Muffenverbinder nur reinen Zugspannungen ausgesetzt sind, treten bei den Hülsenrverbindern meist zusätzliche Biegungsbeanspruchungen auf, welche beisonders die Leiterenden an der Austrittstelle aus dter Hülse einknicken und bei entsprechender Steigerung des Seilzuiges die \~erbindung zerstören.As clamp connections for tensioned electrical lines, wire pulls, etc. are mainly sleeve connectors and sleeve connectors have become known. While the sleeve connectors are only subjected to pure tensile stress are exposed, the sleeve connectors usually experience additional bending stresses which bend especially the conductor ends at the point of exit from the sleeve and destroy the connection if the rope pull is increased accordingly.

Die neue Hülsenverbindung vermeidet sie und besteht in ihrer Grundform (Längsschnitt Abb. ι und Querschnitt Abb. 2) aius einer flachgedrückten Hülse, die in Richtung der Zugspannungslinien in einer gesdhlwungenen Form leicht gebogen ist. Durch diese Bauart . wird das verbiegende Moment diurch den Seilzug (vgl. die punktierte Gerade in Abb. 1) vermieden. Die in den Ebenen senkrecht zur Richtung der gespannten Leitung entstehenden Beanspruchungen erzeugen Reibungskräfte, welche zwischen den zu verbindenden und klemmenden Konstruktionsteilen zur Wirkung kommen und d'amit teils die dem Seilzug besonders wider stehenden Gegenkräfte schaffen, teils zur Ursache eines kleinsten elektrischen Widerstandes werden. Je weniger widerstandsfähig gegen die knikkende Biegung und je dicker die zu verbindenden Enden sind, um so vorteilhafter wird der neue Verbinder verwendet werden. Die Enden können in der ein- oder mehrschaligen Hülse durch passende Eindrückuwgen oder durch eingebrachte klemmende Maschinenelemente beliebiger Zahl und Anordnung, z. B. Niete und Schrauben (vgl. Abb. 3), erfolgen. Audi· bei dieser Befestigungsart wird durch die geschwungene Grundform das zerstörende Biegungsmoment mit Sicherheit vermieden, und es ist auch bei stärkeren Seifen nicht notwendig, zur Aufrechterhaltung des Sicherheitsgrades der ganzen Leitungsahlagie die Hülse unverhältnismäßig lang .und schwer zu maichen, damit die zerstoßen den Drücke dies bei gerader Hülse auftretenden Momentes infolge der Verlängerung des Hebelarmes klein werden.The new sleeve connection avoids them and exists in its basic form (longitudinal section Fig. Ι and cross-section Fig. 2) aius a flattened sleeve, which in the direction of the Tension lines in a curved shape is slightly curved. With this design . the bending moment is caused by the cable pull (see the dotted straight line in Fig. 1) avoided. Those arising in the planes perpendicular to the direction of the tensioned line Stresses generate frictional forces between the structural parts to be connected and clamped Effect come and therefore partly the counter-forces particularly resisting the cable pull create, sometimes become the cause of the smallest electrical resistance. The less resistant to the kinking bend and the thicker the joint Ends, the more advantageous the new connector will be. The ends can be single or multi-shell Sleeve through suitable impressions or through inserted clamping Machine elements of any number and arrangement, e.g. B. rivets and screws (cf. Fig. 3). Audi · with this type of mounting, the curved Basic shape avoided the destructive bending moment with certainty, and it is also at stronger soaps not necessary to maintain the level of security all over the line ahlag, the sleeve is disproportionately long. and difficult to make, so the crush the pressures this at straighter Sleeve occurring moment due to the extension of the lever arm become small.
