Abstract

The contact pieces of a contact arrangement for vacuum switches are formed by individual segments. The latter are assembled at a certain distance from one another to form the circular contact piece and are fixed on a carrier board. This results in the production of slots which run in the radial direction being manufactured without any need for costly metal-cutting machining.

Description

Kontaktanordnung für VakuumschalterContact arrangement for vacuum switch

Die Erfindung betrifft eine Kontaktanordnung für Vakuumschalter nach den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a contact arrangement for vacuum switches the features of the preamble of claim 1.

Bei bekannten Kontaktstücken werden die Schlitze durch spanabhebende Bearbeitung eingebracht.In known contact pieces, the slots are made by cutting Machining introduced.

Die Aufgabe der Erfindung ist es, die Herstellung der Kontaktstücke zu vereinfacen.The object of the invention is to produce the contact pieces to simplify.

Die Lösung gelingt mit den kennzeichnenden Merkmalen des Anspruches 1.The solution succeeds with the characterizing features of the claim 1.

Zum Pressen der relativ kleinen Segmente wird ein geringer Preßdruck benötigt. Sie werden in einer Lötvorrichtung mit Abstand zueinander (Schlitzbildung) auf der Trägerplatte aneinandergereiht und mit dieser verbunden Durch die Beabstandung der Segmente zueinander entsteht ein durchgehender Schlitz in vertikaler Richtung. Eine spanabhebende Bearbeitung, wie Fräsen oder Sägen, ist entbehrlich.A low pressing pressure is used to press the relatively small segments needed. They are spaced apart in a soldering device (slot formation) lined up on the carrier plate and connected to it by the spacing of the segments to each other creates a continuous slot in the vertical direction. There is no need for machining such as milling or sawing.

Ohne Änderungen der Segmentabmessungen erhält man ein Kontaktstück für eine geringere Nennstromstärke, wenn man den Segmentabstand vergrößert und weniger Segmente verwendet. Der Kontaktstückdurchmesser bleibt dabei unverändert.A contact piece is obtained without changing the segment dimensions for a lower nominal amperage if one increases the segment spacing and less Segments used. The contact piece diameter remains unchanged.

Der Schlitzverlauf kann in den sich gegenüberliegenden Kontaktstücken gleich oder entgegengesetzt sein, je nachdem, ob ein axiales oder ein radiales Magnetfeld für die Kontaktanordnung angestrebt wird.The course of the slot can be in the opposing contact pieces be the same or opposite, depending on whether an axial or a radial magnetic field is sought for the contact arrangement.

Ein Ausführungsbeispiel soll die Erfindung näher erläutern.An exemplary embodiment is intended to explain the invention in more detail.

Fig. 1 zeigt ein Kontaktstück in Drauf- und Seitenansicht mit vier Segmenten; Fig. 2 ein solches mit 3 Segmenten.Fig. 1 shows a contact piece in plan and side view with four Segments; Fig. 2 shows one with 3 segments.

Die Segmente 1 sind jeweils - einander beabstandet - auf einer Trägerplatte 2 aus Edelstahl aufgelötet.The segments 1 are each - spaced from one another - on one Carrier plate 2 made of stainless steel soldered on.

Der rückwärtig eingelötete Stromzuführungsbolzen 3 ragt nicht bis zur Kontaktoberfläche vor, so daß in Kontaktstückmitte eine Vertiefung 4 gelassen ist. Die Schlitze 5 sind durchgehend, d.h.The power supply bolt 3 soldered to the rear does not protrude to the contact surface, so that a recess 4 is left in the center of the contact piece is. The slots 5 are continuous, i. E.

sie reichen von der Vertiefung 4 bis zur Peripherie des Kontaktstückes.they extend from the recess 4 to the periphery of the contact piece.

Einem flachen zentralen Bereich 6 des Kontaktstückes schließt sich ein nach außen hin abfallender Bereich 7 an.A flat central area 6 of the contact piece closes an outwardly sloping area 7.

Beim Kontaktstück nach Fig. 1 sind vier Segmente 1 innerhalb eines Kreises aneinandergereiht, bei jenem nach Fig. 2 nur drei bei gleichem Kontaktstückdurchmesser, jedoch zwangsläufiger VergröNerung der Schlitzbreite.In the contact piece according to FIG. 1, there are four segments 1 within one Circle strung together, in the one according to Fig. 2 only three with the same contact piece diameter, but inevitable enlargement of the slot width.
