Description

Träge ansprechende Schmelzsicherung Es ist bekannt, träge ansprechende Schmelzsicherungen dadurch zu erzielen, daß. der überdimensionierte: Schmelzleiter mit einem Lotauftrag versehen wird der bei starker Erwärmung eine Legierung mit dem Schmelzleiter eingeht, die die Leitfähigkeit und damit die Belastbarkeit des überdimensionierten Scbmelzleiters herabsetzt. Es ist ferner bekannt, die Belastbarkeit des Schmelzleiters durch eine Wärmestauung an einer bestimmten Stelle herabzusetzen. Man hat ferner vorgeschlagen, durch die Verwendung eines bestimmten Materials für den Schmelzleiter eine trage ansprechende Schmelzsicherung zu erzielen.Slowly responding fuse It is known to be slow responding To achieve fuses that. the oversized: fusible link A solder is applied to it, which, when it is very hot, is combined with an alloy the fusible link, which affects the conductivity and thus the load capacity of the oversized fusible link. It is also known the resilience of the fusible conductor by an accumulation of heat at a certain point. It has also been suggested through the use of a certain material for To achieve a fusible link that is pleasant to wear.

Die meisten bekannten Anordnungen zur Erzielung einer überstronnträgen Sicherung haben den Nachteil, wie dies insbesondere bei einem Lotauftrag der Fall ist, daß der Leiterquerschnitt und damit die zu verdampfende Metallmasse an der Abschmelzstelle vergrößert wird. Mit den übrigen bekannten Mitteln kann eine Trägheit nur in beschränktem Umfang erzielt -%irerden.Most of the known arrangements for achieving an overflow Fuses have the disadvantage, as is the case in particular with a solder application is that the conductor cross-section and thus the metal mass to be evaporated on the The melting point is enlarged. With the other known means, an inertia Achieved only to a limited extent - earth%.

Gemäß der Erfindung wird eine träge ansprechende Schmelzsicherung dadurch erzielt, , daß der vorzugsweise aus Silber bestehende überdimensionierte Schmelzleiter stellenweise mit einer Umhüllung aus Kupferchlorid mit einem Bindemittel versehen wird, wobei das bei höheren Temperaturen frei werdende Chlor den Schmelzleiter zerstört. Das Kupferchlorid kann auch. dem Füllmittel beigemischt sein.According to the invention, there is a slow-acting fuse achieved by the fact that the oversized one, which is preferably made of silver Fusible conductor in places with a sheathing made of copper chloride with a binding agent is provided, with the chlorine released at higher temperatures the fusible link destroyed. The copper chloride can also. be added to the filler.

Diese Anordnung hat den Vorteil, daß an der Schmelzstelle keine zusätzlichen Metallmassen vorhanden sind. Zur Erzielung der Trägheit wird ein nichtleitendes Mittel verwendet, das bei einer bestimmten Temperatur den Schmelzleiter teilweise zerstört und den Leiterquerschnitt verkleinert.This arrangement has the advantage that there are no additional ones at the melting point Metal masses are present. In order to achieve inertia, a non-conductive one is used Means used that at a certain temperature the fusible link partially destroyed and the conductor cross-section reduced.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, worin a den Schmelzleiter, ä die Umhüllung aus Kupferchlorid und c das Füllmittel bezeichnet.An embodiment of the invention is shown in the drawing, where a the fusible conductor, ä the copper chloride sheath and c the filler designated.
