Abstract

Bei einem Hochspannungs-Leistungsschalter mit einer Isolierstoffdüse (3) soll an deren erstem, der Antriebsseite abgewandten Ende (6) ein im Schaltfall anzutreibendes Bauteil angekoppelt werden, das auf der der Antriebsseite gegenüberliegenden Seite der Trennstrecke angeordnet ist. Zu diesem Zweck weist die Isolierstoffdüse eine umlaufende Wulst (7) auf, über die ein erster Spannring (8) unter elastischer Verformung des Spannrings oder des Düsenendes geschoben werden kann. Danach wird ein zweiter Spannring (10) am Düsenende befestigt, der sowohl den ersten Spannring (8) als auch das Düsenende stützt und somit eine Entriegelung des ersten Spannrings (8) verhindert.

Figure 00000001
In the case of a high-voltage circuit breaker with an insulating nozzle (3), a component to be driven in the switching case, which is arranged on the side of the isolating section opposite the drive side, is to be coupled to its first end (6) which faces away from the drive side. For this purpose, the insulating material nozzle has a circumferential bead (7) over which a first clamping ring (8) can be pushed while the clamping ring or the nozzle end is deformed elastically. A second clamping ring (10) is then attached to the nozzle end, which supports both the first clamping ring (8) and the nozzle end and thus prevents the first clamping ring (8) from being unlocked.
