Description

Es ist üblich, bei Kabeiendverschlüssen, die direkt mit dem Kabelbleimantel durch Lotung verbunden werden, das Erdungsseil unterhalb des Endverschlusses auf den Bleimantel zu löten. Diese Anordnung ist nachteilig, da durch die Lötwärme eine gewisse Verdrängung der Kabeltränkmasse durch starke örtliche Erwärmung und Ausdehnung erfolgt, zumal bereits eine starke Erwärmung durch die Schmierplombe zur Verbindung des Endverschlußgehäuses mit dem Bleimantel unvermeidlich ist. Hierdurch kann die elektrische Festigkeit an der Verbindungsstelle örtlich stark herabgesetzt werden.It is common practice for cable terminations that attach directly to the lead sheath of the cable be connected by plumbing, the earthing cable below the termination to solder the lead jacket. This arrangement is disadvantageous because a certain displacement of the cable penetration mass due to strong local heating and expansion takes place, especially since there is already strong warming from the lubrication seal for the connection of the end cap with the lead jacket is inevitable. This allows the electrical strength at the connection point are locally greatly reduced.

Die Erfindung hat sich die Aufgabe gestellt, diese Nachteile zu vermeiden und eine Anbringungsart des Erdungsseiles zu finden, bei der durch Abstrahlen der beim Anlöten des Erdungsseiles entstehenden Wärme die. Bandwicklung der Kabeladern im Innern des Endverschlußgehäuses nicht unzulässig heiß wird. Erfindungsgemäß ist am. unteren, insbesondere konisch ausgebildeten Ende des Endverschlusses, welcher den Übergang zum Kabelmantel bildet, eine ringförmige Sieke zur Aufnahme des Erdungsseiles vorgesehen. In diese Sieke wird das Erdungsseil eingelegt und verlötet, so daß es vollkommen versenkt angebracht ist und einen einwandfreien Sitz aufweist, wodurch die Lotung vereinfacht wird. Die beim Löten hervorgerufene Erwärmung des Gehäuses kann nicht unmittelbar auf die empfindlichen Kabeladern strahlen, sondern nur auf das Ende des Bleimantels, das immer in einer entsprechenden Länge in das Gehäuse eingeführt wird. Auch das gute Aussehen des fertigen Endverschlusses wird durch das aufgelötete Erdungsseil nicht beeinträchtigt.The invention has set itself the task of avoiding these disadvantages and to find a way of attaching the grounding cable, in which by radiating the when soldering the earthing cable, the heat generated. Tape winding of the cable cores inside the end cap does not get excessively hot. According to the invention at the lower, in particular conical end of the end closure, which forms the transition to the cable sheath, an annular sieve to accommodate the earthing cable intended. The earthing cable is inserted into this sieve and soldered so that it is mounted completely sunk and has a perfect fit, whereby the plumbing is simplified. The heating of the housing caused by soldering can not shine directly on the sensitive cable cores, but only on the end of the lead jacket, which is always in a corresponding length in the housing is introduced. Also the good appearance of the finished termination is through does not affect the soldered-on earthing cable.

In der Figur ist ein Ausführungsbeispiel der Erfindung dargestellt. Der Kabelendverschluß besteht im wesentlichen aus einem zylindrischen Gehäuse i aus Blei oder Blech, welches an seinem unteren Ende einen konischen Tei12 aufweist, der durch eine Schmierplombe 3 (Zinnlotung) mit dem Bleimantel 4 des Kabels verbunden ist. Der Bleimantel q. ragt bis in das Innere des Gehäuses i. Daran anschließend ist eine Gürtelisolierung 5 vorhanden, aus welcher die einzelnen Kabeladern 6, welche mit Kunststoffbändern bewickelt sind, austreten.In the figure, an embodiment of the invention is shown. The cable termination consists essentially of a cylindrical housing i made of lead or sheet metal, which has a conical part at its lower end, which is connected to the lead sheath 4 of the cable by a lubricant seal 3 (tin solder) is. The lead jacket q. protrudes into the interior of the housing i. After that there is a belt insulation 5, from which the individual cable cores 6, which are wrapped with plastic tape.

Gemäß der Erfindung ist in dem unteren konischen Teil 2 des Endverschlusses eine Sieke 7 vorgesehen, in welche das Erdungsseil 8 eingelegt und angelötet wird. Das Erdungsseil8 ist somit vollkommen versenkt angebracht, so daß der Seilring 8 um den konischen Teil 2 durch das Lot 9 verdeckt ist. Hierdurch wird eine glatte Fläche auf dem konischen Teil 2 erzielt.According to the invention, in the lower conical part 2 of the end closure a sieve 7 is provided, in which the grounding cable 8 is inserted and soldered. The earthing cable 8 is thus attached completely sunk so that the cable ring 8 around the conical part 2 is covered by the solder 9. This makes a smooth Surface achieved on the conical part 2.
