The two adapter parts 1 and 2 enclose in the mounted state, an axial end part 3 of a first catenary component at least non-positively.

Bei dem in FIG 1 gezeigten ersten Oberleitungsbauteil 4 handelt es sich um einen Isolator (Kunststoffisolator).The first overhead line component 4 shown in FIG. 1 is an insulator (plastic insulator).

Das Abschlußteil 3 des Isolators 4 weist einen runden Querschnitt auf, der (in axialer Richtung des axialen Abschlußteils 3 betrachtet) zunächst konstant ist, sich anschließend verringert und dann wieder vergrößert.The termination part 3 of the insulator 4 has a round cross-section, which (initially viewed in the axial direction of the axial end part 3) is initially constant, then reduced and then enlarged again.

Das axiale Abschlußteil 3 des Isolators 4 wird im dargestellten Ausführungsbeispiel nicht nur kraftschlüssig, sondern auch formschlüssig von den beiden Adapterteilen 1 und 2 umschlossen. Die beiden Adapterteile 1 und 2 sind hierzu in ihren einander zugewandten Ausformungen entsprechend an den sich in axialer Richtung verändernden Querschnitt des axialen Abschlußteils 3 angepaßt.The axial end part 3 of the insulator 4 is in the illustrated embodiment not only frictionally, but also positively enclosed by the two adapter parts 1 and 2. The two adapter parts 1 and 2 are adapted for this purpose in their mutually facing formations corresponding to the axially varying cross-section of the axial end part 3.

Beide Adapterteile 1 und 2 sind weiterhin zumindest kraftschlüssig mit einem zweiten Oberleitungsbauteil 5 verbunden. Bei dem zweiten Oberleitungsbauteil 5 handelt es sich um ein Rohr (Hohlprofil). Solche Rohre sind z. B. als Auslegerrohre oder Spitzenrohre Bestandteil von Auslegerkonstruktionen.Both adapter parts 1 and 2 are further connected at least non-positively to a second overhead line component 5. The second overhead line component 5 is a tube (hollow profile). Such tubes are z. As a boom pipes or tip tubes part of boom structures.

Anschließend wird das axiale Abschlußteil 3 mit den beiden aufliegenden Adapterteilen 1 und 2 in das Rohr 5 eingeführt. Die Einführung des axialen Abschlußteils 3 wird durch einen Bund 6 und 7 begrenzt, der an den beiden Adapterteilen 1 und 2 angeordnet ist.For the positive and non-positive connection between the insulator 4 and the tube 5, first the two adapter parts 1 and 2 are placed on the axial end part 3 of the insulator 4 such that the adapter parts 1 and 2 enclose the axial end part 3 in a form-fitting manner. Subsequently, the axial end part 3 is inserted with the two adjacent adapter parts 1 and 2 in the tube 5. The introduction of the axial end part 3 is limited by a collar 6 and 7, which is arranged on the two adapter parts 1 and 2.

Nach dem Einschieben des axialen Abschlußteils 3 in das Rohr 5 bzw. nach dem Aufschieben des Rohrs 5 auf das axiale Abschlußteil 3 wird die Verbindung durch einen Spannstift 8 gesichert. Die Adapterteile 1 und 2 sowie das Rohr 5 weisen hierzu eine gemeinsame Bohrung auf, in die der Spannstift 8 einführbar ist.After insertion of the axial end portion 3 in the tube 5 and after pushing the tube 5 on the axial end part 3, the connection is secured by a dowel pin 8. The adapter parts 1 and 2 and the tube 5 have for this purpose a common bore into which the clamping pin 8 can be inserted.

Anstelle des Spannstiftes 8 kann das Rohr 5 auch auf die beiden Adapterteile 1 und 2 aufgeschrumpft werden. Als weitere Alternative kann das Rohr 5 mit den beiden Adapterteilen 1 und 2 auch verpreßt werden. Für diese Variante muß die Außenumfangsfläche der Adapterteile 1 und 2 eine Riffelung aufweisen. Als weitere Variante ist es möglich, das Rohr 5 mittels einer ersten Schneidschraube mit dem Adapterteil 1 und mittels einer zweiten Schneidschraube mit dem Adapterteil 2 zu verbinden.Instead of the clamping pin 8, the tube 5 can be shrunk onto the two adapter parts 1 and 2. As a further alternative, the tube 5 with the two adapter parts 1 and 2 are also pressed. For this variant, the outer peripheral surface of the adapter parts 1 and 2 must have a corrugation. As a further variant, it is possible to connect the tube 5 to the adapter part 1 by means of a first tapping screw and to the adapter part 2 by means of a second tapping screw.
