Anbringen von Schaltmitteln zur FunkenlöschungAttachment of switching devices for spark extinction
Beschreibung: Description :
Gleichstrom-Kleinstmotoren unterliegen in vielen Fällen, insbesondere bei Uhren, häufigen Schaltvorgangen. Dabei wird vielfach eine der Bürsten als Schalter benutzt. Die sich einstellende Gefährdung von Kollektor und Bürsten durch Bürstenfeuer und Abschaltfunken wird durch Anbringen von Schaltmitteln zur Funkenlöschung, in bekannter Weise, vermieden. Man schaltet beispielsweise einen ohmschen Widerstand oder eine Kapazität oder eine Induktivität parallel zu jeder Ankerwicklung. Der Kollektor von Kleinstmotoren ist vielfach gemäß Fig. 1 ausgebildet, indem die-Kollektorlamelle 1 und die Lötfahne 2 ein gemeinsames Stück· bilden. Die Lötfahnen 2 dienen zum Anlöten der Wicklungs-anden und müssen bei Verwendung von Schaltmitteln zur Funkenlöschung auch als Lötstellen für diese verwendet werden. Das Anlöten von Schaltmitteln von Lötfahne zu LÖtfahne erfordert eine hohe Geschicklichkeit oder komplizierte Hilfsvorrichtungen, welche durch die bei den Kleinstmotoren notwendigen Miniaturbauteile noch erschwert werden. Aus diesen Gründen ist das Anbringen einzelner Schaltmittel in der bisher bekannten Weise für eine Serienfertigung ungeeignet.In many cases, especially in the case of clocks, DC miniature motors are subject to frequent switching operations. Included one of the brushes is often used as a switch. The emerging risk of collector and brushes from brush fire and switch-off sparks are avoided by installing switching means for spark extinction in a known manner. One switches for example an ohmic resistance or a capacitance or an inductance in parallel with each armature winding. Of the The collector of miniature motors is often designed as shown in FIG. 1, in that the collector lamella 1 and the solder lug 2 have a common Piece · form. The soldering lugs 2 are used to solder the winding ends and must be used when using switching means Spark quenching can also be used as soldering points for this. The soldering of switching devices from soldering lug to soldering lug requires a high level of dexterity or complicated auxiliary devices, which are required by the micro-motors Miniature components are even more difficult. For these reasons, the attachment of individual switching means is previously known Way unsuitable for series production.
Die Neuerung bezieht sich auf eine einfache und wirtschaftliche Anbringung der besciiriebenen Schaltmittel, Erfindungsgemäß benutzt man einen drei- bezw. mehrarmigen Ring 3 nach Fig. 2, welcher in Form einer gedruckten Schaltung an drei Armen 4 einen Kupferbelag 5 un(3· eine Bohrung zum Einführen der dargestellten Anschlußdrähte für die Widerstände 6 aufweist. Bei der AbmessungThe innovation relates to a simple and economical attachment of the switching means described. multi-armed ring 3 according to FIG. 2, which in the form of a printed circuit on three arms 4 has a copper coating 5 un ( 3 · a bore for inserting the connecting wires shown for the resistors 6
