Description

Das Patent 88q.672 betrifft eine Vorrichtung, bei der ein einwandfreier Stromübergang zwischen Kontaktschiene und Fußkontakt dadurch erreicht wird, daß durch federnde Organe an der Sicherungspatrone bzw. dem Selbstschalter eine kraftschlüssige Verbindung mit der Paßschraube der Fußkontaktschiene hergestellt wird.The 88q.672 patent relates to a device in which a flawless Current transfer between the contact rail and foot contact is achieved in that a non-positive connection through resilient elements on the fuse cartridge or the circuit breaker Connection with the fitting screw of the foot contact rail is made.

Neben einer sicheren Wirkungsweise wird außerdem von einer derartigen Vorrichtung verlangt, daß sie sehr einfach und mit geringen Kosten hergestellt werden kann. Gemäß der Erfindung wird diese Forderung dadurch erfüllt, daß der Fußkontaktzapfen als federnde Wendel ausgeführt ist.In addition to a safe mode of operation, there is also such a Apparatus requires that they be manufactured very simply and at low cost can. According to the invention, this requirement is met in that the foot contact pin is designed as a resilient helix.

Die Zeichnung zeigt alsAusführungsbeispiel der Erfindung das Fußteil eines Selbstschalters.The drawing shows the foot part as an embodiment of the invention an automatic switch.

Auf dem Fußteil i des Selbstschalters befindet sich zum Einschrauben in ein Sicherungselement -der Gewindering 2, der gleichzeitig als Stromübertrager für den einen Pol dient. Den anderen Polanschluß bildet der Fußkontaktzapfen 3. Dieser besitzt eine Bohrung 4.; in den rohrförmigen Zapfen ist eine Wendel 5 eingeschnitten. Wird der Selbstschalter in das Sicherungselement eingeschraubt, so wird die Wendel zusammengedrückt und stellt eine kraftschlüssige Verbindung mit der Paßschraube des Sicherungselementes her. Damit wird zunächst eine Lockerung der Verbindung zwischen Fußkontakt und Paßschraube weitgehend verhindert. Tritt aber dennoch durch gewisse Umstände eine Lockerung ein, so wird durch die Nachfederung der Wendel doch noch ein einwandfreier Kontakt gewährleistet, und schädliche Verschmorungen der Kontaktstelle werden verhindert.On the foot part i of the automatic switch is to be screwed in in a securing element - the threaded ring 2, which also acts as a current transformer serves for one pole. The other pole connection is formed by the foot contact pin 3. This has a bore 4 .; A helix 5 is cut into the tubular pin. If the circuit breaker is screwed into the fuse element, the coil becomes compressed and provides a positive connection with the fitting screw of the fuse element. This first loosens the connection between Foot contact and fitting screw largely prevented. But still occurs through certain If circumstances allow for a loosening, the rebounding of the helix will after all a perfect contact is guaranteed, and harmful charring of the contact point are prevented.
