Kabelabspannklemme. Patentiert im Deutschen Reiche vom 24. Dezember 1922 ab. Cable tension clamp. Patented in the German Empire on December 24, 1922.

Die Erfindung bezieht sich auf eine Abspannklemme für armierte Schwachstromluftkabel, welche aus einem mehrfach geteilten Konus und einer zweckmäßig zweiteiligen Spannmuffe besteht, an welcher der Zugbügel angreift. Es hat sich gezeigt, daß ein solcher Zugbügel, der an den Enden mit Gewinde versehen ist und mittels Muttern an Augen der Spannmuffe befestigt wird,, durch die auftretenden Biegungsbeanspruchungen leicht bricht, da sich die durch 'das Gewinde bewirkte Schwächung gerade am gefährlichen Querschnitt befindet.The invention relates to a tensioning clamp for armored low-voltage air cables, which consists of a multiply divided cone and an expedient two-part clamping sleeve on which the tension bracket attacks. It has been shown that such a tension bracket, which is provided at the ends with a thread is and is fastened by means of nuts to eyes of the clamping sleeve, through the occurring Bending stress breaks easily because it is caused by 'the thread The weakening is just at the dangerous cross-section.

Nach der Erfindung wird dieser Fehler dadurch beseitigt, daß an der Muffe vor den der Befestigung dienenden Augen besondere, die Bügelarme vor dem Gewinde abstützende Führungen vorgesehen sind.According to the invention, this error is eliminated in that on the sleeve before the special eyes that are used for fastening, support the bracket arms in front of the thread Guided tours are provided.

In den Abbildungen ist ein Ausführungsbeispiel des Gegenstandes der Erfindung ge- ao An exemplary embodiment of the subject matter of the invention is shown in the figures

zeigt, und zwar ist Abb. ι -ein Längsschnitt durch die Klemme, während Abb. 2 einen Querschnitt gemäß der Linie I-I in Abb. 1 veranschaulicht.shows, namely Fig. ι -a longitudinal section through the clamp, while Fig. 2 shows a cross-section along the line I-I in Fig. 1 illustrated.

Das Telephonkabel besteht aus einer mit einem Bleimantel fr umkleideten Kabelseele, einer Eisenbandarmierung e und einer Drahtarmierung d. Das Eisenband ist derart angeordnet, daß die einzelnen Lagen sich nicht überlappen, sondern nebeneinander liegen, so daß durch den Druck der Klemme keine -vorstehenden Kanten in den Bleimantel eingedrückt werden können. Das Kabel wird in der Klemme zunächst von einem aus drei Teilen kv k2, ks bestehenden Konus umgeben, dessen Innenfläche durch eine bearbeitete, aber mit Aufrauhungen versehene. Fläche gebildet wird, während die Außenfläche sorgfältig bearbeitet ist. Nahe den Enden weist der Konus je eine Rille r auf, in die nach Anordnung der Konusteile auf dem Kabel ein Bindedraht h fest eingelegt wird, so daß die Konusteile gut gegen das Kabel angepreßt und auch in ihrer Längsrichtung gegeneinander festgelegt sind.The telephone cable consists of a cable core sheathed with a lead sheath for, an iron band armoring e and a wire armoring d. The iron band is arranged in such a way that the individual layers do not overlap, but lie next to one another, so that no protruding edges can be pressed into the lead jacket by the pressure of the clamp. The cable is initially surrounded in the terminal by a cone consisting of three parts k v k 2 , k s , the inner surface of which is machined but provided with roughening. Surface is formed while the outer surface is carefully machined. Near the ends of the cone each has a groove r into which a binding wire h is firmly inserted after the cone parts have been arranged on the cable, so that the cone parts are pressed well against the cable and are also fixed against each other in their longitudinal direction.

Der Konus wird von einer Muffe umgeben, die aus zwei Teilen W1, m2 besteht. Diese Teile sind mittels Paßstifte p derart aufeinandergefügt, daß die innere Konusfläche genau hergestellt ist. Zur Verbindung der Hälften Mi1, m2 dienen vier durch Flansche / gezogene Schraubenbolzen s. Der Abspannbügel μ ist mit jedem Ende durch je zwei Vorsprünge V1, V2 der Muffenteile mx, Wv2 geführt. Beiderseits der Vorsprünge V2 sind Muttern t auf den Bügel aufgeschraubt, so daß dieser unverschiebbar an der Muffe gehalten ist. Die Bohrung der Vorsprünge V1 dient dazu, die bei der Zugbeanspruchung in dem Abspannbügel auftretenden Seitenkräfte aufzunehmen, so daß in dieser Richtung in den mit Gewinde versehenen Teilen keine Beanspruchungen auftreten.The cone is surrounded by a sleeve which consists of two parts W 1 , m 2 . These parts are joined together by means of dowel pins p in such a way that the inner conical surface is precisely produced. The halves Mi 1 , m 2 are connected by four screw bolts pulled through flanges / s. The tensioning bracket μ is guided at each end through two projections V 1 , V 2 of the socket parts m x , Wv 2. On both sides of the projections V 2 nuts t are screwed onto the bracket so that it is held immovably on the sleeve. The bore of the projections V 1 serves to absorb the lateral forces occurring in the tensioning bracket in the tension, so that no stresses occur in the threaded parts in this direction.
