Abstract

Die Erfindung betrifft eine Kontaktanordnung eines Relais mit einem Kontaktkopf (11) mit einer eine Kontaktfläche (15) umschliessenden, gegenüber der Kontaktfläche vorspringenden Krone (17). Erfindungsgemäss ist zur Erhöhung der Kontaktsicherheit bei trockener Schaltlast diese Krone (17) an einer Vielzahl von Stellen unterbrochen, wodurch Zacken (21) und Zwischenräume zwischen den Zacken (21) gebildet sind. Dieser Kronen-Kontaktkopf liegt in geschlossener Stellung der Kontaktanordnung geneigt an einem kronenlosen Kontaktkopf an. Die den beweglichen Kontaktkopf tragende Kontaktfeder (23) ist verwindbar ausgebildet. Dies ergibt, dass der Kronen-Kontaktkopf (11) den kronenlosen benachbarten Kontäktkopf (25) jeweils mit hoher spezifischer Flächenpressung an sicher zwei kleinflächigen Berührungsstellen berührt.

The invention relates to a contact arrangement of a relay with a contact head (11) with a crown (17) enclosing a contact surface (15) and projecting relative to the contact surface. According to the invention, this crown (17) is interrupted at a plurality of points to increase the contact reliability with dry switching load, whereby prongs (21) and spaces between the prongs (21) are formed. This crown contact head is in the closed position of the contact arrangement inclined to a crownless contact head. The movable contact head bearing contact spring (23) is formed twistable. This results in that the crown contact head (11) touches the crownless adjacent Kontäktkopf (25) each with high specific surface pressure to safely two small-area contact points.
