Description

Kontaktfeder für elektrische Vorrichtungen. Bei elektrischen Kontakteinrichtungen, insbesondere solchen mit schleifenden Kontakten, benutzt man bisher zumeist Federn aus Nickel, Neusilber, Bronze o. dgl:, die trotz ihrer sonstigen, z. B. in Bezug auf die Leitfähigkeit, guten Eigenschaften den Nachteil haben, daß sie von Säuren oder deren Dämpfen angegriffen werden und unter Umständen hinsichtlich ihres Metallgehaltes Beschaffungsschwierigkeiten machen.Contact spring for electrical devices. With electrical contact devices, springs have mostly been used up to now, especially those with sliding contacts made of nickel, nickel silver, bronze o. the like: which despite their other, z. B. in relation on conductivity, good properties have the disadvantage that they are of acids or their vapors are attacked and possibly with regard to their metal content Make procurement difficulties.

Die Erfindung beseitigt diese Nachteile ohne Beeinträchtigung der den bekannten Kontaktfedern eigenen Vorteile dadurch, daß die Kontaktfedern aus einer Legierung von Eisen oder Stahl mit Vanadium bestehen.The invention overcomes these disadvantages without affecting the the known contact springs have their own advantages in that the contact springs are made of an alloy of iron or steel with vanadium.

Dieser Legierung können zur Erzielung besonderer Eigenschaften des Metalles noch andere Metalle, wie z. B. Nickel oder Wolfram, zugesetzt werden.This alloy can be used to achieve special properties of the Metal nor other metals, such as. B. nickel or tungsten can be added.

Kontaktfedern gemäß der Erfindung werden von Säuren oder deren Dämpfen fast gar nicht angegriffen und eignen sich auch zur Herstellung von Berührungskontakten, da sie hinsichtlich der elektrischen Leitfähigkeit derjenigen der Edelmetalle wenig nachstehen und sich auch gut löten lassen.Contact springs according to the invention are made from acids or their vapors almost not attacked at all and are also suitable for making touch contacts, since they have little in terms of the electrical conductivity of that of the noble metals inferior and can also be soldered well.
