Description

Unverlierbare und untrennbare Anordnen Befestigungsschrauben auf Isoliersockeln Elektrisch` Geräte Um die Befestigungsschrauben von Isoliersockeln, beispielsweise elektrischer Fassungen, unverlierbar zu machen, ist es bekannt, dieselben durch Ringe aus Draht, Gummi, Pappe o. dgl. zu sichern. Ein solcher Ring wird, nachdem die Sehraube mit Zahnscheibe, Druckfeder o. dgl. durch das Schraubenloch des Sockels gesteckt ist; auf dem Schaft der Schraube aufgebracht und verhütet das Herausfallen derselben in nichtbefestigtem Zustande des Sockels. Ebenso leicht wie diese Sicherungsmittel aufgebracht werden können, können sie auch wieder entfernt werden.Captive and inseparable arrangement of fastening screws on insulating bases Electrical `devices To the fastening screws of insulating bases, for example electrical sockets to make captive, it is known to use the same To secure rings made of wire, rubber, cardboard or the like. Such a ring will after the visual hood with toothed washer, compression spring or the like through the screw hole of the base is plugged; applied to the shaft of the screw and prevents it from falling out the same in the non-attached state of the base. Just as easy as these securing devices can be applied, they can also be removed again.

Sind nun bei keramischen Sockeln elastische Unterlagen, z.: B. Federn,- unter den Köpfen der Befestigungsschrauben vorgesehen, welche das Brechen der Sockel bei starken Stößen verhindern sollen, so kann @es beispielsweise bei Reparaturen vorkommen, daß diese Sicherungsmittel entfernt und die Sockel fest und starr angeschraubt werden.Are elastic bases, e.g. springs, - provided under the heads of the fastening screws that prevent the breaking of the socket in the event of strong impacts, @es can, for example, be used for repairs it can happen that these securing means are removed and the base is screwed on tightly and rigidly will.

Um dieses sicher zu verhindern, wird erfindungsgemäß die Schraube mit der Feder usw: untrennbar mit dem Sockel verbunden. Zu diesem Zweck ist das Gewinde der Befestigungsschraube vor dem gewindelosen, Schaft derselben in einer Breite, die etwas geringer als die Höhe einer Mutter ist, bis zum Kerndurchmesser eingestochen.In order to reliably prevent this, the screw according to the invention with the spring, etc .: inextricably linked to the base. For that purpose this is Thread of the fastening screw in front of the unthreaded, shaft of the same in one Width slightly less than the height of a nut, up to the core diameter stabbed.

Bei dem dargestellten Ausführungsbeispiel ist in Abb. i diese Schraube i dargestellt. Die Breite des- eingestochenen Teils 1t ist etwas geringer als die Höhe h1 der Schlitzmutter 2 in Abb. 2. Wird nun, wie in Abb. 3 dargestellt, die Schraube i mit einer Druckfeder g :durch das Loch des im Schnitt gezeichneten Sockels q. gesteckt, die Schlitzmutter z aufgeschraubt, mit einem Schlüssel festgehalten und die Schraube mit einem Schraubenzieher fest angezogen, so verquetschen sich die letzten Gewindegänge von Schlitzmutter und Schraube, die Schlitzmutter dreht sich in dem eingestochenen Teil der Schraube und läßt sich nicht mehr entfernen. Mithin sind alle Teile untrennbar verbunden und können so in einem Gehäuse o. dgl. festgeschraubt werden.In the illustrated embodiment, this screw is in Fig. I i shown. The width of the pierced part 1t is slightly smaller than that Height h1 of the slotted nut 2 in Fig. 2. Now, as shown in Fig. 3, the Screw i with a compression spring g: through the hole in the base drawn in section q. inserted, screwed on the slotted nut z, held in place with a key and tighten the screw with a screwdriver, so squeeze yourself the last threads of the slotted nut and the screw that the slotted nut turns is in the pierced part of the screw and can no longer be removed. Thus, all parts are inseparably connected and can be in a housing or the like. be screwed tight.
