Schalter der gezeigten Art haben einen Nennstrom von bis zu mehreren hundert Ampere. Im Kurzschlussfall treten enorme Kräfte und Beschleunigungen auf, die mit einer entsprechenden Materialbeanspruchung einhergehen.switch of the type shown have a rated current of up to several hundred Amp. In the event of a short circuit, enormous forces and accelerations occur associated with a corresponding material stress.
Bei einer Öffnung der Kontakte im Kurzschlussfall, bei dem einige Kiloampere auftreten können, tritt ein starker Lichtbogen auf, der mit einem Materialabtrag im Inneren des Gerätes einhergeht. Herkömmliche Schalter haben nur eine begrenzte Lebensdauer und eine entsprechend reduzierte Funktionssicherheit. Diese Probleme werde durch eine häufige Beanspruchung des Schalters weiter verschärft.at an opening the contacts in the event of a short circuit, in which some kiloamps occur can, If a strong arc occurs, with a material removal in the Inside of the device accompanied. conventional Switches have only a limited life and a corresponding reduced functional reliability. These problems will be solved by a frequent Stress of the switch further aggravated.
Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Schaltwelleneinheit für einen Schalter vorzuschlagen.Of the Invention is based on the object, an improved switching shaft unit for one To propose switch.
Diese Aufgabe wird mit einer Schaltwelleneinheit mit den Merkmalen des Patentanspruchs 1 gelöst.These Task is with a switching shaft unit with the features of Patent claim 1 solved.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.advantageous Further developments of the invention will become apparent from the dependent claims.
Die
vorgeschlagene Schaltwelleneinheit umfasst ein zylindrisches Element
Bei
der vorgeschlagenen Schaltwelleneinheit ist eine Abdeckung
Durch eine solche Anordnung der Komponenten der Schaltwelleneinheit kann ein Eindringen von losen Bestandteilen in das Innere der Schaltwelleneinheit sicher vermieden werden. Ein durch ein solches Eindringen auftretendes Blockieren von Komponenten der Schaltwelleneinheit, die zu einem Funktionsausfall oder einer Funktionsbeeinträchtigung des Schalters führen, können somit sicher vermieden werden.By Such an arrangement of the components of the switching shaft unit can Ingress of loose components in the interior of the switching shaft unit safely avoided. An occurring by such an intrusion Blocking components of the switching shaft unit, resulting in a malfunction or a functional impairment lead the switch, can thus safely avoided.
Vorteilhafterweise
ist die Abdeckung
Die Öffnung
Auch
wird die Abdeckungswirkung durch eine kleinere Öffnung
Die Abdeckung lässt sich mittels einer gekrümmten Platte herstellen, die dem Verlauf des Mantels des zylindrischen Elements hülsenartig folgt. Der Radius der Innenseite der Abdeckung ist dabei geringfügig größer als der Radius der Mantelfläche des zylindrischen Elementes. Hierdurch wird eine Verdrehbarkeit der Abdeckung gegenüber dem zylindrischen Element erreicht. Darüber hinaus handelt es sich bei dieser Art der Ausführung der Abdeckung um die wohl platzsparendste Abdeckung, da kein zusätzlicher Platzbedarf erforderlich ist.The Cover leaves by means of a curved Produce plate, the course of the shell of the cylindrical Element sleeve-like follows. The radius of the inside of the cover is slightly larger than the radius of the lateral surface of the cylindrical element. As a result, a twistability of Cover opposite reached the cylindrical element. In addition, it is in this type of execution the cover around the probably most space-saving cover, there no additional Space is required.

Der
Kontaktarm
Vorteilhafterweise weist das zylindrische Element zwei Öffnungen an gegenüber liegenden Seiten des Mantels des zylindrischen Elementes auf. Auch die Abdeckung weist dementsprechend zwei gleich große Öffnungen auf, so dass der Kontaktarm aus beiden Öffnungen des zylindrischen Elementes ragt und beide Öffnungen der Abdeckung durchdringt. Bei dieser Anordnung wird die Abdeckung gegenüber dem zylindrischen Element gleichzeitig durch beide Enden des Kontaktarmes verschoben.Advantageously, the cylindrical Ele ment two openings on opposite sides of the shell of the cylindrical element. The cover also has two equal openings, so that the contact arm protrudes from both openings of the cylindrical element and penetrates both openings of the cover. In this arrangement, the cover is displaced simultaneously with respect to the cylindrical member through both ends of the contact arm.
Alle in den Unteransprüchen angegebenen Merkmale können mit dem Gegenstand gemäß Patentanspruch 1 einzeln oder in einer beliebigen Anzahl kombiniert werden. Alle denkbaren Kombinationen der Merkmale des gesamten Anspruchssatzes, mit Ausnahme der Ansprüche 6 und 7, sind somit Bestandteil der Offenbarung der vorliegenden Anmeldung.All in the subclaims specified characteristics can with the article according to claim 1 individually or in any number can be combined. All conceivable combinations of the features of the entire set of claims, with Exception to the claims 6 and 7, are thus part of the disclosure of the present Registration.
