Abstract

The joint housing, for covering cable joints, has two side walls and a covering arranged such that a thin metal sheet can be laid inside the housing on additional cylindrical surfaces formed on the side walls. The overlap has an adhesive or vulcanising coating and is embedded in the cylindrical surfaces. In the case of a vulcanising coating the cylindrical surfaces are pretreated to enable the vulcanising coating to adhere to them. Additional elastic coverings are placed over the overlap under the outer covering to reinforce the seal. Where the cable enters the housing, the hole in the wall is of greater diameter than the cable and the cable is gripped by a conical grommet.

Description

Kabelmuffe Die einführung der Kunststoffe in die Esbeltechnik führte tu der Entwicklung neuer Muffen, da die bei den Pspierbleikabeln übliche Muffe aus Blei auf den Mänteln der neuen Kabel nicht anwendbar ist. Als Muffen für Kunststoffkabel sind viele Konstruktionen vorgeschlagen worden, und ein Teil ist auch zur Anwendung gekommen. Bei der praktischen Anwendung ergeben sich jedoch eine Reihe von Schwierigkeiten mit allerdings unterschiedlichem Ausmass bei den einzelnen Konstruktionen: Ausbildung des Personals für bisher in der Kabel technik nicht übliche Arbeitsverfahren Aufwand zusätzlicher Geräte und Werkzeuge Schwierige Öffnung bei Reparatur oder Umschaltung Ungünstige Verhältnisse zwischen Aussenabmessungen der Muffen und ihrem Spleissraum Teure werkzeuge für die Herstellung der Muffen. Cable sleeve The introduction of plastics into Esbel technology do the development of new sleeves, as the sleeve that is common with lead wire cables Lead on the sheaths of the new cables is not applicable. As sleeves for plastic cables Many constructions have been proposed and a part is also in use came. However, a number of difficulties arise in practical application to a different extent, however, in the individual constructions: training of the staff for work processes that were previously not common in cable technology additional devices and tools Difficult to open when repairing or switching Unfavorable relationships between the outer dimensions of the sleeves and their splice space Expensive tools for making the sleeves.

Als Vorteil gegenüber der Bleimuffe ist das niedrigere Gewicht der Kunststoffmuffen anzusetzen.The advantage over the lead sleeve is the lower weight of the To apply plastic sleeves.

Uberlegungen für bessere Lösungen fahren zu der Erkenntnis sinnvoll Konstruktionselemente aus Metall Kunststoff zusammenzufassen, Metall für Stabilität und Schutz, für die Dichtung Kunststoff in handelsüblicher Porm als Meterware.Considerations for better solutions lead to the realization being meaningful Metal construction elements Plastic summarize, metal for stability and protection, for the seal, plastic in commercially available form sold by the meter.

Die praktische Konstruktion dieser Lösung sieht vor, dass an sichbekannte Muffenkonstruktionen mit zwei Seitenwänden aus Metall, mit durin enthaltenen Einführungstutzen für die Kabel und mit einem Aussenmantel aus Metall, derart ergänzt werden, dass im Innern der Muffe auf zylindrischen Zusatzflächen der Seitenwände ein dünnes Metallblech aufgelegt wird, das in der Überlappung mit einem klebenden oder anxtulksnisierenden Belag versehen ist und auf der zylindrischen Auflagefläche in einem elastischen klebenden oder anvulkanisierenden wickel eingebettet ist.The practical construction of this solution provides that known per se Sleeve constructions with two side walls made of metal, with insertion nozzles included for the cables and with an outer sheath made of metal, so that inside the sleeve on additional cylindrical surfaces of the side walls a thin sheet of metal is applied, which is in the overlap with an adhesive or anxtulksnisierenden Covering is provided and on the cylindrical bearing surface in an elastic adhesive or vulcanizing wrap is embedded.

Das aild zeigt die wesentlichen Merkmale der Kontruktion.The picture shows the main features of the construction.

Als Einführungsstätzen ist nur eine mögliche Form dargestellt, in die Seitenwand einvulkanisierte Stutzen, die passend zum Kabeldurchmesser geschnitten werden. ktenso möglich sind Stopfbuchsen mit thermoplastischem Dichtungsmaterial. Der äussere Muffenmantel ist zweckmässig zweigeteilt, um bei ungunstig*n Montageorten leicht aufgelegt werden zu können. Die beiden Muffenseitenwände sind durch zwei gewölbte Längsstreben miteinander verbunden und bilden eine feste Unterlage für das Aufbringen der Dichtung in der Längsnaht. Auf den zylindrischen Seitenflächen ist das dünne Metallblech in dem klebenden oder anvulkanisierenden Wickel eingebettet.Only one possible form is shown as introductory clauses, in the side wall vulcanized-in nozzles that are cut to match the cable diameter will. Stuffing boxes with thermoplastic sealing material are also possible. The outer sleeve jacket is expediently divided into two parts in order to avoid unfavorable installation locations easy to put on. The two socket side walls are through two arched longitudinal struts connected to each other and form a solid base for the application of the seal in the longitudinal seam. On the cylindrical side surfaces the thin metal sheet is embedded in the adhesive or vulcanizing winding.

Die Montage stellt keine erhöhten Anforderungen an das Personal, es werden keine zusätzlichen Werkzeuge benötigt. als Dichtungsmaterial z.B. wird doppelseitig klebendes elastisches thermoplastisches Band in handelsüblicher Lieferart verwendet.The assembly does not place increased demands on the personnel, it no additional tools are required. as sealing material e.g. is double-sided adhesive elastic thermoplastic tape used in commercial delivery.
