Abstract
Die Erfindung betrifft einen Schaltkontakt (1), dessen Kontaktboden (5) durch Schlitze (10) in Abschnitte (12) und dessen Spulenkörper (4) durch Schlitze (8) in wendel förmige Leiter (9) zur Erzeugung eines Magnetfeldes unter teilt ist. Beim Zusammenwirken mit einem zweiten Schaltkon takt (2) induzieren beide zusammen je nach der Richtung der Schlitze (8) in den beiden Spulenkörpern (4) im geöffneten Kontaktspalt ein axiales oder ein radiales Magnetfeld. The invention relates to a switch contact (1), the Contact base (5) through slots (10) in sections (12) and its bobbin (4) through slots (8) in helix shaped conductor (9) for generating a magnetic field below shares. When interacting with a second Schaltkon clock (2) both induce together depending on the direction of the Slots (8) in the two bobbins (4) in the open Contact gap an axial or a radial magnetic field.
Um in beiden Fällen ein wirksames Magnetfeld zu erzeugen, ist ein gleichmäßig verteilter Stromfluß in den Windungen (9) der Spulenkörper (4) mit wenigstens nahezu parallelen strom fäden in Neigungsrichtung der Schlitze (8) erforderlich. Zur Lösung wird eine besondere Gestaltung des Kontaktbodens (5) mit unterschiedlichen Widerständen vorgeschlagen, so daß auch für die längeren Stromlinien (SL1, SL2 ...) in den Rand zonen der Leiter (9) Pfade mit gleichgroßem elektrischen Widerstand entstehen. In order to generate an effective magnetic field in both cases, is an evenly distributed current flow in the turns (9) the coil body (4) with at least almost parallel current threads in the direction of inclination of the slots (8) required. To Solution is a special design of the contact base (5) proposed with different resistances, so that also for the longer streamlines (SL1, SL2 ...) in the margin Zones of the conductor (9) paths with the same size electrical Resistance arise.
