Als Schmelzsicherung ausgebildeter elektrischer "VerbinderElectrical "connector designed as a fuse
Die Erfindung betrifft einen als Schmelzsicherurig ausgebildeten elektrischen Verbinder.The invention relates to an electrical connector designed as a fusible link.
Man erreicht eine hohe Wirtschaftlichkeit bei der Herstellung eines derartigen Verbinders, wenn man das durchschmelzende Element aus dem gleichen Werkstück fertigt wie den Verbinderkörper. Zu diesem Zweck bedient man sich eines Stückes Kupferrohr, das in der Mitte oder an einem Ende abgeflacht und in die Größe des erforderlichen Schmelzquerschnittes gestanzt wird. Die Dicke des Schmelzquerschnittes wird so das Doppelte der Wandstärke des Kupferrohres.One achieves a high level of economy in the manufacture of such a connector if one manufactures the fusible element from the same workpiece as the connector body. To this Purpose one makes use of a piece of copper pipe that is flattened in the middle or at one end and is punched into the size of the required melt cross-section. The thickness of the melt cross-section becomes twice the wall thickness of the copper pipe.

Die Erfindung bezweckt, einen derartigen, als Schmelzsicherung ausgebildeten elektrischen Verbinder so auszubilden, daß die Fähigkeit des Schmelzteiles, den Bogen abzukühlen und zu deionisieren, erhöht wirde Ferner bezweckt die Erfindung, die Herstellung des Verbinders möglichst wirtschaftlich und ohne Verwendung irgendwelcher zusätzlicher Teile zu gestalten.The invention aims to provide such a fuse trained electrical connector to form so that the ability of the melting part, the arc to cool and deionize, is also intended the invention, the manufacture of the connector as economically as possible and without the use of any to design additional parts.
Die Piguren erläutern die Erfindung an einem Ausführungsbeispiel. Es stellen dar: The Piguren explain the invention using an exemplary embodiment. They represent:

Der durchschmelzbare Verbinder 10 gemäß den Piguren 1 und besteht aus einem Kupferrohr von gewünschtem Durchmesser, Wandstärke und Länge. Je nach der Verwendungsart des Verbinders ist dieser entweder an einem Ende oder in seinem Mittelteil abgeflacht. Der abgeflachte Teil wird in die gewünschte Porm gestanzt, so daß er ein lamelliertes durchschmelzbares Element 12 bildet, von welchem aus sich die den Leiter aufnehmenden Rohrteile 14 erstrecken«The fusible connector 10 according to the Piguren 1 and consists of a copper tube of the desired diameter, wall thickness and length. Depending on the type of use of the connector, it is either flattened at one end or in its central part. The flattened part is punched into the desired Porm, so that it forms a laminated durchschmelzbares element 12 from which the conductor-receiving portions extending tube 14 '
Eine derartige Durchschnelzsicncrung ist bekannt als :uaximalstrombegrenzer bei Kraftübertragung,, So hat beispielsweise ein Gerät aus einen Kupferrohr mit einem Außendurchmesser von 1,06 Zoll (ca. 2,5 cm) und einer Wandstärke von 0,113 Zoll (ca. 0,25 cia) die Fähigkeit, unter einer Betriebsspannung von 480 Volt bei ungefähr ' 30 000 Ampere zu unterbrechen, wenn es in einer hitzebeständigen Hülle, die mit Quarzsand gefüllt wird, enthalten ist·Such a cut-through circuit is known as: uaximalstromlimiter bei Kraftverkehr the ability to break at approximately 30,000 amps under an operating voltage of 480 volts when contained in a refractory envelope filled with quartz sand
Überraschenderweise hat sich gezeigt, daß sich die Unterbrechungskapazität nahezu verdoppelt, wenn man die durch, die abgeflachten Rohrwandungen gebildeten Lamellen des durchschmelzbaren Seiles auseinanderspreizt.Surprisingly, it has been shown that the interruption capacity almost doubled if the fins formed by the flattened pipe walls of the fusible rope spreads apart.
Gemäß Fig. 3 sind diese den schmelzbaren 2eil 12 bildenden Lamellen auf einen Abstand von ungefähr 1/2 Zoll (ca.'1,25 cm) auseinandergespreizt, so daß sie zwei parallele Wege bilden. Dieser Abstand ist ausreichend, um eine reichliche Menge. von Quarzsand 20 zwischen die Lamellen eintreten zu lassen; >'die dem Sand ausgesetzte Oberfläche wird hierdurch nahezu verdoppelt. Eine hitzebeständige Hülle 22 hält das bogenlöschende Material 20 zusammen. Auf diese Weise wird die Fähigkeit des Begrenzers, den Bogen zu kühlen und zu deionisieren, beträchtlich erhöht,«,As shown in Figure 3, these fusible lamellae 12 forming the fusible part 12 are spaced approximately 1/2 inch apart. spread apart so that they form two parallel paths. This spacing is sufficient to keep an ample amount. to allow quartz sand 20 to enter between the lamellae; > 'the surface exposed to the sand becomes almost as a result doubled. A heat-resistant sleeve 22 holds the arc-extinguishing material 20 together. In this way, the Ability of the limiter to cool and deionize the arc, considerably increased, "
Die Erfindung ist nicht auf das beschriebene und gezeichnete Ausführungsbeispiel beschränkt.The invention is not restricted to the exemplary embodiment described and drawn.
