Um Kontaktfedern o. dgl. auf beiden Seiten an einander gegenüberliegenden Stellen mit Kontaktstücken, z. B. Plättchen, zu vergehen, verbindet man Feder und Kontaktstücke durch Zusammenpressen miteinander. Eine solche Verbindung ist wenig haltbar.To contact springs or the like on both sides at opposite points with contact pieces, e.g. B. platelets to pass, you connect spring and contact pieces by pressing together. Such a connection is not very durable.

Nach der im folgenden beschriebenen Erfindung wird eine dauerhafte Verbindung dadurch erzielt, daß die Kontaktstücke durch ίο eine Bohrung der Feder hindurch miteinander verschweißt werden.According to the invention described below, a permanent connection is thereby achieved achieved that the contact pieces through ίο a hole in the spring with each other be welded.

Bestehen die Kontaktstücke aus Metall, welches so hoch schmilzt, daß die Feder durch die Schweißhitze zerstört werden würde, so wird jedes Kontaktstück mit einem Ansatz aus leichter schweißbarem Stoff, wie z. B. Eisen, versehen, und es werden diese Ansätze zusammengeschweißt.The contact pieces are made of metal, which melts so high that the spring through the welding heat would be destroyed, so each contact piece is with a shoulder made of more easily weldable material, such as B. iron, and there are these approaches welded together.

Dieses Ausführungsbeispiel der Erfindung ao ist in den Abb. 1 und 2 in je einem Längsschnitt veranschaulicht; Abb. 3 ist ein Grundriß. Die Zeichnung ist der Deutlichkeit halber in vergrößertem Maßstabe gehalten. Die Kontaktfeder 1 soll auf beiden Seiten mit je einem Kontaktplättchen 2 versehen werden, das aus einem hochschmelzenden Metall, z.B. Wolfram, besteht. Die Plättchen 2 werden hierzu mit Plättchen 3 aus Eisen o. dgl. verschweißt, die je einen Zapfen 4 haben. Jedes Plättchen 2, 3 wird so an die Feder 1 gelegt, daß sein Zapfen 4 in deren Bohrung 5 ragt. Die Zapfen 4 werden durch Punktschweißung miteinander verbunden. Dies geschieht mittels Elektroden 6, welche gegen die Plättchen 2 gelegt werden. Das fertige Erzeugnis ist aus Abb. 2 zu sehen, wo die Schweißstelle der Zapfen mit 7 bezeichnet ist.This embodiment of the invention ao is in Figs. 1 and 2 in a longitudinal section illustrates; Fig. 3 is a plan. For the sake of clarity, the drawing is on an enlarged scale. The contact spring 1 should be provided with a contact plate 2 on each side made of a refractory metal such as tungsten. The platelets For this purpose, 2 are welded to platelets 3 made of iron or the like, each of which has a pin 4 have. Each plate 2, 3 is placed on the spring 1 that its pin 4 in their Hole 5 protrudes. The pins 4 are connected to one another by spot welding. This is done by means of electrodes 6 which are placed against the platelets 2. That The finished product can be seen from Fig. 2, where the welding point of the tenons is indicated by 7 is.

In gleicher Weise können mehrere Kontaktstücke einer Seite der Feder mit einem einzigen Kontaktstück der anderen Seite verbunden werden.In the same way, several contact pieces can one side of the spring with one single contact piece on the other side.
