Description

Die Erfindung bezieht sich auf eine Niederspannungs-Hochleistungs-Sicherung, nachfolgend NH-Sicherung genannt, mit einer Anzeigeeinrichtung nach Art von Federblechanzeigern, wobei der an einer Platine befestigte Anzeigeschmelzleiter durch die andere Platine hindurchgeführt und an einem Federblatt unter Vorspannung befestigt ist, so daß beim Durchschmelzen das Federblatt seine Lage als optische Anzeige verändert. Wenn keine Zusatzfunktionen benötigt werden, haben Federblechanzeiger gegenüber den auch gebräuchlichen Bolzenanzeigern den Vorteil, daß sie wirtschaftlicher herzustellen und zu montieren sind.The invention relates to a low-voltage high-performance fuse, hereinafter referred to as NH fuse, with a display device in the manner of spring plate indicators, the indicator fuse attached to a circuit board being passed through the other circuit board and fastened to a spring leaf under pre-tension, so that when When the spring leaf melts, its position changes as a visual display. If no additional functions are required, spring plate indicators have the advantage over the common pin indicators that they are more economical to manufacture and assemble.

Der Erfindung liegt die Aufgabe zugrunde, eine NH-Sicherung mit einem besonders zuverlässigen Federblechanzeiger zu entwickeln, der sich auch besonders wirtschaftlich montieren läßt.The invention has for its object to develop a NH fuse with a particularly reliable spring plate indicator, which can also be installed particularly economically.

Die Lösung der geschilderten Aufgabe besteht darin, daß das Federblech aus zwei übereinanderliegenden Schenkeln, einem Basisschenkel und einem schmaleren Anzeigeschenkel, die gewölbt miteinander verbunden sind, gebildet ist, daß in der Wölbung bis zu den planen Schenkeln und in den Schenkelenden Schlitze ausgebildet sind und daß der Anzeigeschmelzleiter am Anzeigeschenkel befestigt ist und durch den Schlitz in der Wölbung nach außen geführt und am Schlitz in den Schenkelenden durch ein Loch in der Platine hindurchgeführt ist.The solution to the described problem is that the spring plate is formed from two superimposed legs, a base leg and a narrower display leg, which are arched together, that slots are formed in the curvature up to the flat legs and in the leg ends and that the display fuse element is fastened to the display leg and is guided outwards through the slot in the arch and is passed through a hole in the circuit board at the slot in the leg ends.

Eine NH-Sicherung mit einem solchen Federblechanzeiger gewährleistet einerseits mechanisch bedingt und andererseits wegen der sich ergebenden Zugentlastung des Anzeigeschmelzleiters durch die besondere Führung am Federblechanzeiger, eine zuverlässige Anzeige, ob die Sicherung durchgeschmolzen ist. Da beim Ansprechen der Sicherung keine Teile vom Anzeiger abfallen können, ist eine solche NH-Sicherung auch beim Einsatz in Anlagen besonders betriebssicher. Der Schlitz am Schenkelende des Anzeigeschenkels dient dabei der Führung und Lagesicherung des Anzeigeschmelzleiters.An NH fuse with such a spring plate indicator ensures mechanical reasons on the one hand and on the other hand Due to the resulting strain relief of the fuse element through the special guide on the spring plate indicator, a reliable indication of whether the fuse has blown. Since no parts can fall off the indicator when the fuse responds, such an NH fuse is also particularly reliable when used in systems. The slot at the leg end of the display leg is used to guide and secure the position of the display fuse element.

Eine Weiterbildung der NH-Sicherung besteht darin, daß aus der Platine, die den Federblattanzeiger trägt, Nieten herausgeprägt sind, die so auf Nietlöcher im Basisschenkel abgestimmt sind, daß das Ende des Schlitzes im Basisschenkel ein weites Durchführungsloch in der Platine fast bis auf den Durchmesser des Anzeigeschmelzleiters abdeckt. Dadurch erübrigt sich das sonst erforderliche gesonderte Abdichten des Durchführungsloches in der Platine, die den Federblattanzeiger trägt. Solche Durchführungslöcher können wegen der Materialstärke der Platine nicht beliebig fein ausgebildet werden und es muß vermieden werden, daß Sand der Löschfüllung der NH-Sicherung aus dem Durchführungsloch verloren wird. Der Federblechanzeiger dient also zugleich zum Abdichten des Durchführungsloches. Hierbei ist es günstig, wenn das Ende des Schlitzes im Basisschenkel V-förmig verjüngt mit kleiner Rundung an der Wurzel ausgebildet ist.A further development of the NH fuse is that rivets are embossed out of the board that carries the spring leaf indicator, which are so matched to rivet holes in the base leg that the end of the slot in the base leg has a wide through hole in the board almost to the diameter of the display fuse element. This eliminates the otherwise necessary separate sealing of the through hole in the board that carries the spring leaf indicator. Such through holes can not be made arbitrarily fine because of the material thickness of the board and it must be avoided that sand of the extinguishing filling of the NH fuse is lost from the through hole. The spring plate indicator thus also serves to seal the through hole. It is advantageous here if the end of the slot in the base leg is tapered in a V-shape with a small rounding at the root.

Eine wirtschaftliche Montage bei sicherem Betrieb, da keine Teile beim Ansprechen des Anzeigeschmelzleiters verloren gehen können, besteht darin, daß der Anzeigeschmelzleiter am Anzeigeschenkel angeschweißt ist.An economical assembly with safe operation, since no parts can be lost when the fuse element responds, is that the fuse element is welded to the indicator leg.

The invention will be explained in more detail with reference to an exemplary embodiment shown roughly schematically in the drawing:
  • In Fig. 1 a NH fuse with spring plate indicator is ver simply reproduced in longitudinal section.
  • In Fig. 2 the supervision of the spring sheet indicator is shown.
  • In Fig. 3 a section through the spring sheet indicator according to FIG. 2 taken along III-III is shown.
  • 4 shows a spring plate indicator in the untensioned state, that is to say not fully assembled, in a side view.
  • In Fig. 5, a spring sheet indicator without fuse element is shown in side view.
  • 6 shows the top view of the spring plate indicator according to FIG. 5.
  • In Fig. 7 the spring plate indicator according to Fig. 5 is shown in side view looking in the direction of arrow VII.
  • In Fig. 8, the stamping out of rivets is illustrated on a broken piece of board.

Die NH-Sicherung nach Fig. 1 besteht im wesentlichen aus einem Arbeitsschmelzleiter 1 in einem Gehäuse 2 mit den Messerkontakten 3. Der Schaltzustand der Sicherung wird angezeigt durch eine Anzeigevorrichtung, die aus einem Federblechanzeiger 4 und einem Anzeigeschmelzleiter 5 besteht. Der Anzeigeschmelzleiter 5 ist an der Platine 6 durch eine Hülse 7 festgeklemmt, die in üblicher Weise zugleich die Einfüllöffnung für den Löschsand verschließt. Der Anzeigeschmelzleiter ist durch die andere Platine 8 durch ein Durchführungsloch 9 hindurchgeführt und an einem Schenkel des Federblechanzeigers 4 befestigt.1 essentially consists of a working fuse 1 in a housing 2 with the knife contacts 3. The switching state of the fuse is indicated by a display device consisting of a spring plate indicator 4 and a fuse element 5. The display fuse element 5 is clamped to the circuit board 6 by a sleeve 7, which at the same time closes the filling opening for the quenching sand in a conventional manner. The display fuse element is passed through the other circuit board 8 through a through hole 9 and fastened to one leg of the spring plate indicator 4.

Der Federblechanzeiger nach Fig. 2 besteht aus einem Federblech, das zwei übereinanderliegende Schenkel bildet, einen Basisschenkel 10 und einen Anzeigeschenkel 11. Beide Schenkel sind, wie aus Fig. 3 deutlicher zu ersehen, durch eine Wölbung 12 miteinander verbunden. Der Anzeigeschenkel 11 ist, wie die Aufsicht nach Fig. 2 zeigt, schmaler als der Basisschenkel 10. In der Wölbung 12 ist bis zu den planen Schenkeln ein Schlitz 13 ausgebildet. Ebenso sind in den Schenkelenden Schlitze 14 und 15 ausgebildet, die an ihrer Wurzel im montierten Zustand fluchten.2 consists of a spring plate, which forms two superimposed legs, a base leg 10 and a display leg 11. Both legs, as can be seen more clearly from FIG. 3, are connected to one another by a curvature 12. The ad Leg 11 is, as the top view of FIG. 2 shows, narrower than the base leg 10. A slot 13 is formed in the curvature 12 up to the flat legs. Likewise, slots 14 and 15 are formed in the leg ends, which are aligned at their roots in the assembled state.

Der Anzeigeschmelzleiter 5 ist an der Innenseite des Anzeigeschenkels 11 angeschweißt, durch den Schlitz 12 nach außen geführt und durch die Schlitze 15 bzw. 14 in den Schenkelenden durch das Durchführungsloch 9 hindurchgeführt. Die Montage beginnt in der Praxis zweckmäßigerweise mit einem Federblechanzeiger nach Fig. 4, der nach Durchführen des Anzeigeschmelzleiters 5, durch das Durchführungsloch 9 hindurch, verspannt wird.The display fuse element 5 is welded to the inside of the display leg 11, passed out through the slot 12 and passed through the through hole 9 through the slots 15 and 14 in the leg ends. In practice, the assembly expediently begins with a spring plate indicator according to FIG. 4, which is clamped through the through hole 9 after the display fuse element 5 has been passed through.

Zur Befestigung des Federblechanzeigers 4 sind im Basisschenkel 10 Nietlöcher 16 ausgebildet, man vergleiche Figuren 2 und 6. Hierzu können aus der Platine 8, die den Federblechanzeiger 4 trägt, Nieten 17 herausgeprägt sein, wie es in Fig. 8 dargestellt ist.To fasten the spring plate indicator 4, 10 rivet holes 16 are formed in the base leg, compare FIGS. 2 and 6. For this purpose, rivets 17 can be embossed from the board 8, which carries the spring plate indicator 4, as shown in FIG. 8.

Wenn die Nieten 17 so auf die Nietlöcher 16 im Basisschenkel 10 des Federblattanzeigers 4 abgestimmt sind, daß das innenliegende Ende des Schlitzes 14 im Basisschenkel 10 ein weites Durchführungsloch 9 in der Platine 8 fast bis auf den Durchmesser des Anzeigeschmelzleiters 5 abdeckt, wie es in Fig. 3 veranschaulicht ist, spart man eine sonst übliche zusätzliche Dichtung des Durchführungsloches 9 ein.If the rivets 17 are so matched to the rivet holes 16 in the base leg 10 of the spring leaf indicator 4 that the inner end of the slot 14 in the base leg 10 covers a wide through hole 9 in the circuit board 8 almost to the diameter of the fuse element 5, as shown in Fig 3 illustrates, one saves an otherwise usual additional seal of the through hole 9.

Es ist günstig, wenn das innenliegende Ende des Schlitzes im Basisschenkel V-förmig verjüngt und mit kleiner Rundung ausgebildet ist, wie es in Fig. 6 dargestellt ist.It is advantageous if the inner end of the slot tapers in a V-shape in the base leg and is designed with a small rounding, as shown in FIG. 6.
