Description
Glühlampenfassung mit Berührungsschutz Gegenstand ,der Erfindung ,ist eine Teilmantelberührungsschutzfassung, bei welcher ein mit Gewinde versehener Mantelteil b, welcher auf idie Fassungskappe a aufgeschraubt wird und zum Befestigen des Fassungssteines .in der Kappe dient, nach dem Zurückschrauben und dem Lösen von der Fassungskappe den Fassungsstein freilegt, indem er einige Millimeter auf einen Schutzmantelteil c zurückfällt, der mit einem Isolierlampentraggewind e d und mit einem .spannunbgführenden Gewindekorb e zu einem einheitlichen Werkstück zusammengearbeitet ist, durch welches der Berührungsschutz beim Einschrauben der Lampe erzielt wind und :dessen Teil c,der Verdeckung des eingeschraubten Lampensockels dient.Incandescent lamp holder with protection against accidental contact is the subject matter of the invention a partial jacket contact protection socket, in which a threaded jacket part b, which is screwed onto the socket cap a and for attaching the socket stone . Serves in the cap after screwing it back and loosening it from the socket cap exposes the setting stone by placing a few millimeters on a protective jacket part c falls back, the one with an insulating lamp thread e d and with a voltage-carrying thread Thread basket e is worked together to form a uniform workpiece, through which the contact protection when screwing in the lamp achieved wind and: its part c, the Covering the screwed-in lamp base is used.
In der Abbildung ist die Teilmantelberührungsschutzfassung im Längsschnitt dargestellt.The figure shows the partial jacket contact protection socket in longitudinal section shown.
Der Fassungsstein bildet mit dem rückschraubbaren Mantelring b und dem einheitlichen Werkstück c, d, e einen zusammenhängenden Fassungsteil, wenn die Laschen des spannungführenden Gewindekorbes e des einheitlichen Werkstückes c, d, e mittels Sehräubchen am Fassungsstein befestigt sind.The setting stone forms with the screw-down jacket ring b and the uniform workpiece c, d, e a coherent mounting part, if the Lugs of the live thread basket e of the uniform workpiece c, d, e are attached to the setting stone by means of boning.
Das Gewinde des Lampensockels erhält erst Spannung, wenn der beim Einschrauben der Lampe in die Fassung berührbare metallische Teil des Lampensockels durch den Mantelteil c der Berührung entzogen ist.The thread of the lamp base is only tensioned when the Screwing the lamp into the socket touchable metallic part of the lamp base is withdrawn from contact by the jacket part c.
Die Vorzüge der vorliegenden Erfindung bestehen i. darin., d@aß der Berührungsschutz ohne federnde Teile erreicht ist, 2. darin, daß zum Befestigen und Lösender Zuleitungsdrähte die Fassung nur in zwei Teile zerlegt wird, 3. :darin, daß der Fassungsteil, welcher der Erzielung des Berührungsschutzes leim Einschrauben der Lampe und der Verdeckung des eingeschraubten Lampensockels dient, ohne Demontage der übrigen Fassung mittels Werkzeugs vom Fassungsstein abgeschraubt werden kann, wenn Lampenschirme bis zu 34 mm geringstem Innendurchmesser aufgesteckt werden sollen.The advantages of the present invention are i. in., d @ ate the Contact protection is achieved without resilient parts, 2. in that for fastening and loosening the lead wires, the socket is only dismantled into two parts, 3.: in it, that the socket part, which is used to achieve the contact protection, is screwed in glue the lamp and the cover of the screwed-in lamp base is used without dismantling the rest of the socket can be unscrewed from the socket stone using a tool, if lampshades with an inner diameter of up to 34 mm are to be attached.
