Description

Vorrichtung zur Herstellung eines Leitungsabzweiges mittels normaler Schraubklemmen Soll an eine Freileitung eine Abzweigleitung angeschlossen werden, dann bedient man sich für diesen Zweck der bekannten Abzweigklemmen, welche aus zwei Klemmbacken und einer oder mehreren Klemmschrauben bestehen.Device for the production of a line branch by means of normal Screw terminals If a branch line is to be connected to an overhead line, then one uses the known branch terminals for this purpose, which from consist of two clamping jaws and one or more clamping screws.

Auch die bekannten Leitungsbund- bzw. Endbundklemmen können, wenn sie dafür vorgerichtet sind, für den gleichzeitigen Anschluß einer Abzweigleitung benutzt werden, weil in diesem Fall Abzweig- und Endbundklemme in einem Klemmkörper vereinigt sind. Eine solche kombinierte Klemme hat, im Gegensatz zu der Benutzung einer zusätzlichen Abzweigklemme, den unbestrittenen Vorteil, daß durch die Vereinigung der beiden Klemmen in einem einzigen Körper-eine Klemmstelle eingespart wird, was besonders bei der Verklemmung von Aluminiumleitern als wesentlicher Vorzug angesehen werden muß. Andererseits bringt aber die Verwendung solcher kombinierter Klemmen :eine wesentlich vergrößerte Lagerhaltung mit sich, weil jede Klemmentype und Klemmengröße in beiden Ausführungen am Lager geführt werden muß.The known cable bundle or end collar clamps can, if they are prepared for the simultaneous connection of a branch line can be used because in this case branch and end collar clamps in one clamp body are united. Such a combined clamp has, in contrast to the use an additional branch terminal, the undisputed advantage of that by the union of the two clamps in a single body - one clamping point is saved what Considered an essential advantage especially when aluminum conductors are jammed must become. On the other hand, however, brings the use of such combined clamps : a significantly larger stock keeping with it, because each terminal type and terminal size must be kept in stock in both versions.

Aufgabe ist es nun, eine doppelte Lagerhaltung durch die Schaffung einer geeigneten Konstruktion zu beseitigen, ohne dabei auf die Vorteile der kombinierten Klemmen zu verzichten.The task now is to double inventory by creating a suitable construction to eliminate without sacrificing the advantages of the combined Dispense clamps.

Die Lösung erfolgt durch die Erfindung, nach welcher lediglich der Schraubenkopf der Klemmschraube zu einer Klemmbacke verformt wird, damit ein Abzweigleiter unmittelbar an ihr verklemmt werden kann. Auf diese Weise kann jede normale Klemme seitheriger Ausführung wahlweise als einfache oder als Abzweigklemme benutzt werden. Eine vergrößerte Lagerhaltung kommt nicht in Frage, ebensowenig die Beschaffung und Verwendung vieler einzelner Klemmentypen.The solution is provided by the invention, according to which only the Screw head of the clamping screw is deformed into a clamping jaw, so that a branch conductor can be jammed directly on it. In this way any normal clamp can since then can be used either as a simple or as a branch terminal. Increased storage is out of the question, and neither is procurement and use of many individual terminal types.

Sollten Hauptleitung und Abzweigleitung aus zwei verschiedenen Werkstoffen bestehen, dann tritt an Stelle der Einmetallklemmschraube eine solche aus Zweimetall, wie sie z. B. in Abb. II dargestellt ist.Main line and branch line should be made of two different materials exist, then instead of the one-metal clamping screw there is one made of two-metal, how they z. B. is shown in Fig. II.

Die Abb.I zeigt eine Endbundklemme in normaler bekannter Ausführung in Verbindung mit dem Erfindungsgegenstand, dabei sind a die Endbundklemme, b der Hauptleiter, c die Klemmschraube nach der Erfindung, d der Klemmbolzen für die Abzweigleitung und f die Abzweigleitung.Fig.I shows an end collar clamp in the normal known design in connection with the subject of the invention, with a the end collar clamp, b the main conductor, c the clamping screw according to the invention, d the clamping bolt for the branch line and f the branch line.

Die Abb. II zeigt einen Schraubenverbinder in normaler bekannter Ausführung in Verbindung mit dem Erfindungsgegenstand, wobei die Klemmschraube als Zweimetallstück durchgebildet ist. Dabei sind a der Verbinder, b der Hauptleiter, c die Klemmschraube nach der Erfindung, gleichzei;ig als Zweimetallstück durchgebildet, wobei g das eine und h das zweite Metall ist; i ist der Korrosionsschutz an der Übergangsstelle der beiden Metalle, d der Klemmbolzen für die Abzweigleitung und f die Abzweigleitung.Fig. II shows a screw connector in the normal known design in connection with the subject matter of the invention, the clamping screw being a two-metal piece is trained. A is the connector, b is the main conductor, and c is the clamping screw according to the invention, simultaneously formed as a two-metal piece, where g is the one and h is the second metal; i is the corrosion protection at the transition point of the two metals, d the clamping bolt for the branch line and f the branch line.
