Description
Bei den nachstehend beschriebenen Sicherungen wird der Strom, wie aus Fig. ι zu ersehen ist, durch die beiden Kontakte a mit den Ansätzen b in den von dem Körper g aus Porzellan oder anderem Isoliermaterial gebildeten Hohlraum eingeführt. Dieser Raum wird zweckmäßig durch eine Trennwand d in zwei getrennte Kammern unterteilt, in welche die Kontakte hineinragen. Diese sind ausIn the fuses described below, the current, as can be seen from FIG. 1, is introduced through the two contacts a with the projections b into the cavity formed by the body g made of porcelain or other insulating material. This space is expediently divided by a partition d into two separate chambers into which the contacts protrude. These are off
ίο einem Stück hergestellt, entweder aus vollem Material durch entsprechendes Ausbohren, oder aus Schlitzrohr oder, nahtlosem Rohr mit Einschnitten. Die Kontaktstifte sind derartig eingeschlitzt, daß nach dem Einsetzen in den Isolierkörper die Rohre an ihren oberen Enden mittels einfachen Domes aufgeklappt werden. Der Schnitt nach Fig. 2 stellt eine praktische Herstellungsform für diese Hohiniete' dar. Die Löcher für die Niete besitzen einen ' Ansatz, welcher verhindert, daß die - fertigen Teile zu tief in die Isoliermasse g gesteckt werden, während die Niete selbst durch .Auseinanderklappen am Punkt h am oberen Ende im Körper g festgeklemmt und durch Auffedern im Loch gut geführt sind. An dem anderen Ende des Stiftes befindet sich ein Lappen b, welcher nach Art eines Schlüsselbartes oder eines Ringes in die Öffnung der Fassung' oder des Sockels gesteckt wird. Hierdurch wird erreicht, daß die Stifte vollständig fest in der Fassung sitzen und auch nicht herumgedreht werden können.ίο made in one piece, either from solid material by appropriate drilling, or from slotted tube or seamless tube with incisions. The contact pins are slotted in such a way that, after being inserted into the insulating body, the tubes are opened at their upper ends by means of simple domes. The section according to Fig. 2 represents a practical form of manufacture for this Hohiniete '. The holes for the rivets have an' approach, which prevents the - finished parts are inserted too deep into the insulating compound g , while the rivets themselves by .Auseinand towards one another are clamped at point h at the upper end in body g and are well guided by springing open in the hole. At the other end of the pin there is a tab b, which is inserted into the opening of the socket or the base in the manner of a key bit or a ring. This ensures that the pins sit completely firmly in the socket and cannot be turned around either.
An den Punkten b und b wird der. Sicherungsschmelzdraht an die Stifte angelötet. und über die Trennwand d gespannt. Der obere Teil i der Trennwand mit dem darüberliegenden Sicherungsdraht ragt aus der Sicherung hervor und wird zweckmäßig mit Glas oder Glimmerscheibe k abgedeckt, durch welche der Schmelzdraht sichtbar, kontrollierbar und meßbar erscheint.At points b and b the. Fuse fuse wire soldered to the pins. and stretched over the partition wall d. The upper part i of the partition wall with the overlying fuse wire protrudes from the fuse and is expediently covered with glass or mica disk k , through which the fuse wire appears to be visible, controllable and measurable.
Die beschriebene Kontaktvorrichtung kann auch für Glühlampen verwandt werden; denn auch hier kommt es darauf an, die Teile, welche häufiger ersetzt werden müssen, so billig herzustellen, daß das Abmontieren mehr Kosten verursacht als das Fortwerfen der Teile.The contact device described can also be used for incandescent lamps; because Here, too, it depends on the parts that need to be replaced more frequently cheap to manufacture that dismantling is more expensive than throwing away the Parts.
