Description
Schaltkontaktanordnung mit einem Kontakthebel und einem biegsamen LeiterSwitch contact arrangement with a Contact lever and a flexible conductor
Die Erfindung betrifft eine Schaltkontaktanordnung eines elektrischen Schaltgerätes mit einem Kontakthebel und wenigstens einem mit dem Kontakthebel durch Wärmeanwendung fest verbundenen biegsamen Leiter, wobei an einem Ende des Kontakthebels eine Aufnahmetasche für einen verfestigten Endabschnitt des biegsamen Leiters ausgebildet ist und die Aufnahmetasche eine Bodenfläche und drei etwa rechtwinklig zur Bodenfläche stehende Seitenflächen aufweist.The invention relates to a switch contact arrangement of an electrical switching device with a contact lever and at least one with the contact lever through the application of heat rigidly connected flexible conductor, being at one end of the contact lever a pocket for formed a solidified end portion of the flexible conductor and the receiving pocket is a floor surface and three approximately rectangular to the floor area standing faces having.

Die Anordnung nach der genannten
Neben dem Widerstandsschweißen ist
es auch bekannt, weitere Arten der Verbindung anzuwenden, bei denen

insbesondere das Elektronenstrahlschwei ßen (
Durch die Erfindung soll die Qualität der Verbindung von Kontakthebeln und biegsamen Leitern verbessert werden.The invention aims at the quality of the connection of contact levers and flexible conductors can be improved.
Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, dass die Bodenfläche eine etwa trapezförmig erweiterte und der Endabschnitt eine der Bodenfläche angepasste Gestalt aufweisen.According to the invention, this is Task solved by that the floor area one roughly trapezoidal expanded and the end portion have a shape adapted to the floor area.
Diese ohne zusätzlichen Aufwand mögliche Gestaltung vergrößert den Bindeanteil bei Widerstandslöten oder Widerstandsschweißen und verringert dadurch die Erwärmung durch den in einem Schaltgerät fließenden Strom.This possible design without additional effort enlarges the Binding share in resistance soldering or resistance welding thereby reducing warming through that in a switching device flowing Electricity.
Eine weitere vorteilhafte Eigenschaft ist eine Erhöhung des seitlichen Widerstandsmomentes der Kombination aus Kontakthebel und biegsamem Leiter. Hierdurch steigt die Beständigkeit der Verbindungsstelle von Kontakthebel und biegsamem Leiter gegen die starken Kräfte, die bei der Beanspruchung von Schaltgeräten mit einem Kurzschlussstrom auftreten.Another beneficial property is an increase the lateral section modulus of the combination of the contact lever and flexible conductor. This increases the resistance of the connection point of contact lever and flexible conductor against the strong forces that when switching devices are exposed to a short-circuit current occur.
Ferner erweist sich die Erfindung als vorteilhaft bei automatisierten Fertigungsprozessen, bei denen durch die trapezförmige Gestaltung die Ausrichtung und Zentrierung des biegsamen Leiters relativ zu dem Kontakthebel erleichtert wird.The invention also proves as advantageous for automated manufacturing processes in which through the trapezoidal Design the alignment and centering of the flexible conductor is facilitated relative to the contact lever.
Insbesondere für das Widerstandslöten mit in die Aufnahmetasche einzulegender Lotfolie kann es sich empfehlen, dass die Seitenflächen der Aufnahmetasche unter einem stumpfen Winkel zur Bodenfläche stehen. Hierdurch kommt es zu einer intensiven Berührung des verdichteten Ende des biegsamen Leiters und den Seitenwänden der Aufnahmetasche und demzufolge zu einer weiteren Erhöhung des Bindeanteils.Especially for resistance soldering with in it may be advisable to use the solder that the side faces the receiving bag at an obtuse angle to the floor surface. This leads to an intensive contact of the compacted end of the flexible conductor and the side walls of the receiving pocket and consequently to a further increase in Binding portion.
Durch die Erfindung wird im Ergebnis erreicht, dass der Stromübergang zwischen dem Kontakthebel und dem biegsamen Leiter so erfolgt, als sei der Leiter in das Material des Kontakthebels eingebettet oder einstückig mit diesem. Damit werden der Übergangswiderstand und die Verlustleistung besonders niedrig.The result of the invention is achieved the current transition between the contact lever and the flexible conductor as if the conductor is embedded in the material of the contact lever or in one piece with this. So that the contact resistance and the power loss is particularly low.
