Description

Es ist bekannt, Schleifer für-Meßpotentiometer, insbesondere Meßbrückenpotentiometer, mit einem Kontaktschuh aus Edelmetall zu versehen.It is known to use wipers for measuring potentiometers, in particular measuring bridge potentiometers, to be provided with a contact shoe made of precious metal.

Die Erfindung betrifft eine weitere vorteilhafte Ausbildungsform von ,derartigen Schleifern, und zwar besteht erfindungsgemäß der Kontaktschuh aus einem winklig gebogenen Edelmetall,draht, dessen Winkelspitze in sich verdrillt und zu einer Kontaktperle in sich verschweißt ist. Besonders vorteilhaft eignen sich hierfür Edelmetalle . mit hoher Härte und geringster .Schmierneigung, wie z. B. Platin-Iridium-Legierüngen in Zusammensetzungen von. 6o bis 8o0/9 Platin und 2o bis 40% Iridium, insbesondere 70°/o Platin und 300/0 Iridium.The invention relates to a further advantageous embodiment of , Such grinders, according to the invention, the contact shoe consists of a angled precious metal, wire, the angle tip of which is twisted and closed a contact bead is welded into itself. Are particularly advantageously suitable for this Precious metals. with high hardness and the lowest tendency to lubricate, such as B. platinum-iridium alloys in compositions of. 6o to 8o0 / 9 platinum and 2o to 40% iridium, in particular 70 per cent platinum and 300 per cent iridium.

Schleifer nach der Erfindung lassen sich besonders leicht herstellen und weisen eine sehr hohe Leben,sdaner auf, ohne großen und besonderen Materialaufwand. Gerade der einfache, konstruktive Aufbau aber ist bei ,derartigen Teilen wichtig und von großem Vorteil, da jeder Arbeitsvorgang bei diesen praktisch zur Feinmechanik gehörenden Teilen mit verhältnismäßig hohen. Unkosten verbunden ist. Ein Ausführungsbeispiel eines Schleifers nach der Erfindung wird an Hand der Zeichnung erläutert.Grinders according to the invention are particularly easy to manufacture and have a very high life, sdaner, without large and special material expenditure. However, it is precisely the simple, structural design that is important for such parts and of great advantage, since every work process is practically precision mechanics belonging parts with relatively high. Is associated with an expense. An embodiment a grinder according to the invention is explained with reference to the drawing.

- . Ein Platin-Iridium-Draht i von ungefähr o,o8 mm Durchmesser wird winklig gebogen, wie es in Fig. i dargestellt ist, und in seiner WinkelsPitze 3 in sich verdrillt. Der verdrillte Teil wird zu einer Kontaktperle 2 zusammengeschmolzen, vorzugsweise derart, 4aß sie einen Durchmesser von ungefähr 0,4 bis 0,5 mm hat.-. A platinum-iridium wire i approximately 0.08 mm in diameter is bent at an angle, as shown in FIG. The twisted part is fused together to form a contact bead 2, preferably such that it has a diameter of approximately 0.4 to 0.5 mm.

Je nach Verwendungszweck kann der Kontaktschuh an einen Schleifer angeordnet werden oder aber auch selbst verdrillt als Schleifer verwendet werden.Depending on the intended use, the contact shoe can be attached to a grinder can be arranged or even used twisted as a grinder.
