Title (EN) METHOD AND DEVICE FOR PRODUCING CONTACT ELEMENTS FOR ELECTRICAL SWITCH CONTACTS
(FR) PROCÉDÉ ET DISPOSITIF PERMETTANT DE PRODUIRE DES ÉLÉMENTS DE CONTACT POUR DES CONTACTS DE COMMUTATION ÉLECTRIQUES
(DE) VERFAHREN UND VORRICHTUNG ZUR HERSTELLUNG VON KONTAKTELEMENTEN FÜR ELEKTRISCHE SCHALTKONTAKTE
Abstract:
(EN) The invention relates to a method for optimising the production of electrical switch contacts (3, 4), in particular for vacuum tubes (1), in which method an electrical or electromagnetic field assists and/or effects a sintering process, in which method said sintering process takes place on a metallic carrier, and by means of which method semi-finished contact elements for electrical switch contacts (3, 4), contact elements (5) for electrical switch contacts (3, 4), and/or electrical switch contacts (3, 4), in particular for vacuum tubes (1), are produced.
(FR) L'invention concerne un procédé et un dispositif permettant de produire des éléments de contact pour des contacts de commutation électriques. L'invention vise à optimiser la production de contacts de commutation électriques (3, 4), en particulier pour des tubes à vide (1). A cet effet, l'invention propose un procédé selon lequel un champ électrique ou électromagnétique assiste et/ou provoque un processus de frittage. Selon ce procédé, le processus de frittage a lieu sur un support métallique et ainsi, des demi-produits d'élément de contact pour des contacts de commutation électriques (3, 4), des éléments de contact (5) pour des contacts de commutation électriques (3, 4) et/ou des contacts de commutation électriques (3, 4), en particulier pour des tubes à vide (1), sont produits.
(DE) Um die Herstellung von elektrischen Schaltkontakten (3, 4), insbesondere für Vakuumröhren (1), zu optimieren, wird ein Verfahren, bei dem ein elektrisches oder elektromagnetisches Feld einen Sinterprozess unterstützt und/oder hervorruft, vorgeschlagen, bei dem der Sinterprozess auf einem metallischen Träger stattfindet und dadurch Kontaktelement-Halbzeuge für elektrische Schaltkontakte (3, 4), Kontaktelemente (5) für elektrische Schaltkontakte (3, 4) und/oder elektrische Schaltkontakte (3, 4), insbesondere für Vakuumröhren (1), hergestellt werden.
