Title
(DE) AXIALMAGNETFELD-KONTAKTANORDNUNG
(EN) AXIAL MAGNETIC FIELD CONTACT ARRANGEMENT
(FR) AGENCEMENT DE CONTACTS POUR CHAMP MAGNÉTIQUE AXIAL
Abstract
(DE) Axialmagnetfeld-Kontaktanordnung (AMFK) mit einem Fest- Schaltkontakt und einem in Axialrichtung (A) beweglichen Schaltkontakt (1A, 1B), die jeweils von einer aus einem weichmagnetischen Material bestehenden Scheibeneinlage (2A, 2B) umgeben sind, welche die Magnetfeldstärke eines Axialmagnetfeldes zwischen den beiden Schaltkontakten (1A, 1B) verstärkt.
(EN) The invention relates to an axial magnetic contact arrangement (AMFK) comprising a fixed switching contact and a switching contact (1A, 1B) which can be moved in the axial direction (A), which are respectively surrounded by a disk insert (2A, 2B) made of a soft magnetic material, said disk inserts reinforcing the magnetic field strength of an axial magnetic field between both switching contacts (1A, 1B).
(FR) L'invention concerne un agencement de contacts pour champ magnétique axial (AMFK) comprenant des contacts de commutation (1A, 1B) qui sont respectivement fixe et mobile dans la direction axiale (A) et qui sont chacun entourés par un insert discoïdal (2A, 2B) en matériau magnétique doux qui amplifie l'intensité d'un champ magnétique axial entre les deux contacts de commutation (1A, 1B).
