Abstract

A screw cap for electrical screw fuses, for electrical insulation on a fuse insert on the operating side and for forming an output contact of the fuse which holds a threaded sleeve of electrically conductive material in a pot-shaped cap body of insulating material, both having a viewing window normally left free in their base. According to the invention, it is provided that the cap body (1) has on its inside a bead (2) around whose edge the threaded sleeve (3) engages. <IMAGE>

Description

Schraubkappe für elektrische SchraubsicherungenScrew cap for electrical screw fuses

Die Erfindung bezieht sich auf eine Schraubkappe für elektrische Schraubsicherungen, zur elektrischen Isolation eines Sicherungseinsatzes auf der Bedienungsseite und zur Bildung eines Abgangskontaktes der Sicherung, die in einem topfförmigen Kappenkörper aus Isolierstoff eine Gewindehülse aus elektrisch leitendem Werkstoff hält, wobei beide in der Regel in ihrem Boden ein Sichtfenster freilassen.The invention relates to a screw cap for electrical screw fuses, for electrical insulation of a fuse link on the operating side and to form an outgoing contact of the fuse, which is in a cup-shaped cap body holds a threaded sleeve made of electrically conductive material made of insulating material, wherein both usually leave a viewing window in their bottom.

Bei den üblichen Schraubkappen, wie sie auf dem Markt sind, ist nicht nur die Gewindehülse, sondern auch der Kappenkörper mit einem Gewinde versehen, so daß die Gewindehülse durch Einschrauben in den Kappenkörper gehalten wird. Die Gewindehülse ist ohnehin mit einem Gewinde versehen, um sie in die Gewindebrille der Sicherung einschrauben zu können. Der Kappenkörper kann dabei das Muttergewinde und die Hülse ein Bolzengewinde aufweisen.The usual screw caps as they are on the market are not thread only the threaded sleeve, but also the cap body, so that the threaded sleeve is held by screwing it into the cap body. the Threaded sleeve is already provided with a thread to put it in the threaded glasses to be able to screw in the fuse. The cap body can use the nut thread and the sleeve has a bolt thread.

Die bekannten Schraubkappen, deren Kappenkörper ein Gewinde aufweist, erfordern hohen Montageaufwand, da die Gewindehülse in den Kappenkörper einzuschrauben ist und da ein Schraubgewinde im Kappenkörper sich nur aufwendig herstellen läßt.The known screw caps, the cap body of which has a thread, require high assembly costs, since the threaded sleeve is screwed into the cap body and since a screw thread in the cap body can only be produced with great effort.

Der Erfindung liegt die Aufgabe zugrunde, eine Schraubkappe zu entwickeln, die sich leichter fertigen läßt und deren Kappenkörper auch für sich leichter hergestellt werden kann.The invention is based on the object of developing a screw cap, which is easier to manufacture and whose cap body is also made more easily for itself can be.

Die Lösung der geschilderten Aufgabe besteht nach der Erfindung darin, daß der Kappenkörper an seiner Innenseite einen Wulst aufweist, um dessen Rand die Gewindehülse herumgreift. Um den Wulst, der insbesondere am Uebergang vom Boden zum Sichtfenster ausgebildet sein kann, läßt sich die Gewindehülse leicht in Niettechnik überziehen oder in Bördeltechnik oder Verspinntechnik befestigen.The solution to the problem described is, according to the invention, that the cap body has a bead on its inside, around the edge of which Threaded sleeve grips around. Around the bead, especially at the transition from the ground can be designed to the viewing window, the threaded sleeve can easily be riveted cover or fasten using the flanging technique or spinning technique.

Dabei kann die Gewindehülse, die ohnehin mit einem Gewinde zu versehen ist, um die Schraubkappe in einer Gewindebrille einer Sicherung einzuschrauben, bei der Herstellung in einfacher Weise in den Kappenkörper eingesteckt werden.The threaded sleeve can be provided with a thread anyway is to screw the screw cap into a thread goggle of a fuse, are easily inserted into the cap body during manufacture.

Gegen Verdrehen kann die Gewindehülse am Kappenkörper dadurch gesichert werden, daß an ihrem Boden Nuppen ausgebildet sind, die in Bodenvertiefungen des Kappenkörpers eingreifen. Bei einem Kappenkörper aus elastischem Formstoff können hierzu am Boden der Gewindehülse Sikken in den Boden des Kappenkörpers eingedrückt werden.The threaded sleeve on the cap body can thereby be secured against twisting be that at their bottom pods are formed in the depressions of the Engage the cap body. In the case of a cap body made of elastic molded material, you can for this purpose, Sikken is pressed into the bottom of the cap body at the bottom of the threaded sleeve will.

Die Erfindung soll anhand eines in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispiels näher erläutert werden: In Fig. 1 ist eine Schraubkappe axial geschnitten wiedergegeben.The invention is intended to be roughly schematic based on one in the drawing reproduced embodiment are explained in more detail: In Fig. 1 is a Screw cap shown in axial section.

In Fig. 2 ist veranschulicht, wie die Gewindehülse ausgebildet sein kann, um sie in einem Kappenkörper der Schraubkappe nach Fig. 1 befestigen zu können.In Fig. 2 it is illustrated how the threaded sleeve can be designed can in order to be able to fasten them in a cap body of the screw cap according to FIG.

Der Kappenkörper 1 nach Fig. 1 bildet im Ausführungsbeispiel einen umlaufenden Wulst 2, der an der Innenseite des Kappenkörpers 1 ausgebildet ist. Um diesen Wulst greift eine Gewindehülse 3.The cap body 1 according to FIG. 1 forms one in the exemplary embodiment circumferential bead 2 which is formed on the inside of the cap body 1. A threaded sleeve 3 engages around this bead.

Im Ausführungsbeispiel ist der Wulst 2 am Ubergang vom Bo- den des Kappenkörpers 1 zu einem Sichtfenster 6 ausgebildet. Ein so angeordneter Wulst nimmt einem einzuführenden Sicherungseinsatz keinen Raum weg, und er läßt sich bei einer nach Fig. 2 geformten Gewindehülse 3 leicht mit dieser befestigen.In the exemplary embodiment, the bead 2 is at the transition from the bottom the of the cap body 1 formed into a viewing window 6. A bead arranged in this way does not take away any space from a fuse link that is to be inserted, and it allows itself to easily attach a threaded sleeve 3 shaped according to FIG. 2 with this.

Um die Gewindehülse 3 im Kappenkörper 1 gegen Verdrehen zu sichern, sind an ihrem Boden Nuppen 5 ausgebildet, die in zugeordnete Bodenvertiefungen des Kappenkörpers 1 eingreifen.To secure the threaded sleeve 3 in the cap body 1 against twisting, are formed at their bottom knobs 5, which are in associated depressions of the Engage cap body 1.
