Description

Verfahren zur Herstellung von Lötverbindungen an elektrischen Sicherungen - zwischen Schmelzleiter und Anschlußkappen Es sind bisher Verfahren zur Herstellung von Lötverbindungen an elektrischen Sicherungen für Kleinstspannungen bekanntgeworden, bei denen die Kontaktkappen durch Eindrücke an dem Isolierkörper gehalten werden und gleichzeitig der Schmelzleiter durch die Eindrücke mit den Kappen Kontakt erhält. Die Sicherungen wurden nach entsprechender Vorbehandlung in ein Zinnbad getaucht, wobei dann der Schmelzleiter sich an die Kappen anlötete. Dieses Verfahren hat Nachteile, die vor allen Dingen darin zu suchen sind, daß nicht immer eine Lotung zwischen dem Schmelzleiter und den Kontaktkappen zustande kommt. Das Durchschmelzen der Sicherungsschmelzleiter wird dadurch in Frage gestellt.Process for making soldered connections on electrical fuses - Between fusible conductors and connection caps There are so far methods of manufacture became known of soldered connections on electrical fuses for extra-low voltages, in which the contact caps are held by impressions on the insulating body and at the same time the fusible link comes into contact with the caps through the impressions. After appropriate pretreatment, the fuses were immersed in a tin bath, then the fusible link was soldered to the caps. This method has disadvantages which are to be sought above all in the fact that there is not always a plumbing between the fusible conductor and the contact caps comes about. The melting of the fuse fusible link is thereby called into question.

Die Erfindung beseitigt diese Mängel, indem feuer- oder spritzverzinnte Kontaktkappen auf den mit aufgelegten feuer- oder spritzverzinnten Schmelzleiter versehenen Isolierkörper der Sicherung aufgedrückt werden und durch Erhitzen der Sicherung die Zinnschicht auf den Kontaktkappen und dem Schmelzleiter zum Fließen gebracht wird, so daß eine Lötstelle zwischen den - Kontaktkappen und dem Schmelzleiter hergestellt wird.The invention overcomes these deficiencies by hot-dip or spray-tinned Contact caps on the hot-dip or spray-tinned fusible link that is placed on top provided insulating body of the fuse are pressed and by heating the Secure the tin layer on the contact caps and the fuse element to flow is brought, so that a soldering point between the - contact caps and the fusible link will be produced.

In der Zeichnung ist eine Sicherung gemäß der Erfindung dargestellt. Um den Isolierkörper i (in seiner Längsrichtung) ist der Schmelzleiter z gelegt. Über die Enden des Isolierkörpers i nebst dem Schmelzleiter z werden nun die beiden Kontaktkappen 3, die sich in ihren Abmessungen dem Isolierkörper sehr gut anpassen müssen, aufgedrückt. Um ein gutes Aufdrücken zu erreichen, können auch die Enden des Isolierkörpers i etwas konisch sein, damit die Kappen erst .einmal fassen und dann gut fest aufgepreßt werden können. Die Kontaktkappen und der Schmelzleiter sind feuer- oder spritzverzinnt. Durch Erhitzen der gesamten Sicherung entsteht zwischen beiden die Lötstelle.In the drawing, a fuse according to the invention is shown. The fusible conductor z is placed around the insulating body i (in its longitudinal direction). Over the ends of the insulating body i in addition to the fusible conductor z are now the two Contact caps 3, which adapt very well to the insulating body in terms of their dimensions have to, pressed on. In order to achieve a good pressing, the ends can also of the insulating body i should be somewhat conical so that the caps can grip once and can then be firmly pressed on. The contact caps and the fusible link are hot-dip or spray-tinned. Heating the entire fuse is created the solder joint between the two.
