Description
Für die Unterbrechung des Primär stromes bei elektrischen Widerstandsschweißmaschinen werden häufig Druckschalter verwendet. Da die Unterbrechungszahl oftmals eine sehr hohe ist, so ist die Geschwindigkeit, womit die Kontakte aufeinander prallen, dann sehr hoch, und dieses Aufeinanderprallen verursacht daher ein störendes Geräusch.For the interruption of the primary electricity Pressure switches are often used in electrical resistance welding machines. Since the number of interruptions is often very high, the speed is what the contacts collide, then very high, causing this collision hence an annoying noise.
Die Erfindung sieht es vor,, diesen Übelstand dadurch zu beheben, daß Kupferdrahtkörper, z. B. Gazekörper, wie sie beispielsweise als Kollektorbürsten für elektrische Motoren und Dynamos verwendet werden, zur Anwendung gelangen.The invention provides for, this drawback to fix that copper wire body, z. B. gauze bodies, such as those for example used as collector brushes for electric motors and dynamos.
In der Zeichnung ist ein einfaches Ausführungsbeispiel dargestellt. Fig. 1 zeigt einen Pendelschalter, dessen mittleres Konlaktsystem zwischen zwei anderen Kontaktsystemen pendelt. Das mittlere Kontaktsystem besteht aus dem Träger α sowie einem weichen Zwischenstück b, z. B. aus Kupfergaze, und ferner den beiden Kontaktklötzen c und d. Der eine der beiden Gegenkontakte besteht aus dem Träger e, dem weichen Zwischenstück f und dem Kontaktklotz g, während der andere Kontakt aus dem Träger h, dem weichen Zwischenstück i und dem Kontaktklotz k besteht. In diesem Falle sind also die Kupfergazekörper b bzw. / bzw. i nichtA simple embodiment is shown in the drawing. Fig. 1 shows a pendulum switch, the middle Konlaktsystem oscillates between two other contact systems. The middle contact system consists of the carrier α and a soft intermediate piece b, z. B. made of copper gauze, and also the two contact blocks c and d. One of the two mating contacts consists of the carrier e, the soft intermediate piece f and the contact block g, while the other contact consists of the carrier h, the soft intermediate piece i and the contact block k . In this case, the copper gauze bodies b and / or i are not
direkt als kontaktgebende verwendet, sondern nur als schalldämpfende, leitende Unterlagen für die eigentlichen kontaktgebenden Teile.used directly as a contact, but only as a sound-absorbing, conductive base for the actual contacting parts.
In Fig. 2 stellt I den Träger und m einen Kupfergazekontakt dar, welcher unmittelbar den Kontakt, also den Stromschluß, vermitlein soll.In Fig. 2, I represents the carrier and m represents a copper gauze contact which is intended to directly establish the contact, that is to say the current short.
Selbstverständlich könnten an Stelle der Kupfergazekörper auch solche aus gebündelten Drähten zur Verwendung gelangen.Of course, instead of the copper gauze bodies, those made from bundled ones could also be used Wires come to use.
