Description

Verfahren zur Herstellung eines aus einem Blechstück gerollten bananenförmigen Steckerstiftes Dias Zusatzpatent 53o 628 betrifft einen aus einem Blechstück gerollten und oben verschlossenen Steckerstift, der als B:ananensteckerausgebildet ist. Die Bananenform des Steckerstiftes wird in der Weisse hergestellt, daß der fertiggerollte und mit Längsschlitzen versehene zylindrische Steckerstift zur Erzielung der gewünschten Wölbung der Mantelfläche in seiner Längsrichtung gestaucht wird.Method for producing a banana-shaped connector pin rolled from a piece of sheet metal. The additional patent 53o 628 relates to a connector pin rolled from a piece of sheet metal and closed at the top, which is designed as a B: anana connector. The banana shape of the plug pin is made in the white that the finished rolled and provided with longitudinal slots cylindrical plug pin is compressed in its longitudinal direction to achieve the desired curvature of the outer surface.

An den Stellen der größten Wölbung des Bananensteckers besitzen naturgemäß die Schlitze zwischen den gewölbten Mantelflächen die größte Breite. Um eine genügende Federung des Bananensteckers zu serreichen, ist eine verhältnismäßig starke Wölbung der Mantelfläche erforderlich, so daß auch die Schlitze .an den Stellen der größten Wölbung verhältnismäßig breit werden. Diese Schlitzbreite darf jedoch nicht beliebig groß werden, weil nach der Fertigstellung des Röhrensockels durch den Hohlraum des Steckerstiftes die Zuleitungsdrähte zu den Elektroden der Röhre hindurchgesteckt werden und dabei vermieden werden muß, daß: die Zuführungsdrähte seitlich durch die Schlitze des Bananensteckers hindurchtreten können. Die größte Breite der Schlitze muß ,also immer noch kleiner sein ,als der Durchmesser der hindurchzusteckenden Zuführungsdrähte.At the points of the largest bulge of the banana plug naturally have the slots between the curved lateral surfaces have the greatest width. To a sufficient one To obtain the suspension of the banana plug is a relatively strong curvature the outer surface required, so that the slots .at the places of the largest Bulge relatively wide. However, this slot width may not be arbitrary become large because after the completion of the tubular base through the cavity of the Plug pin inserted through the lead wires to the electrodes of the tube and it must be avoided that: the supply wires through the side the slots of the banana plug can pass through. The greatest width of the slots must, therefore, still be smaller than the diameter of the one to be inserted through Lead wires.

Um diese Forderung einer möglichst geringen Breite der Schlitze des Bananensteckers mit der Forderung einer genügend federnden Wölbung der Mantelfläche vereinigen zu können, ist es nicht angängig, die Schlitze vor dem Stauchen zur Bananenform zu sägen oder zu fräsen, weil dadurch zuvi:el Material verlorengehen würde und die Breite der Schlitze bei genügender Wölbung des bananenförmigen Schaftes zu groß werden würde.To meet this requirement of the smallest possible width of the slots Banana plug with the requirement of a sufficiently resilient curvature of the outer surface In order to be able to unite, it is not acceptable to shape the slots into a banana shape before upsetting them sawing or milling, because too much material would be lost and the Width of the slots too large with sufficient curvature of the banana-shaped shaft would be.

Aus diesem Grunde werden gemäß der Erfindung die Schlitze durch Trennen mittels einer Schere, also so hergestellt, daß ein Materialverlust nicht entsteht. Dieses Trennen erfolgt durch zwei horizontale Scherenschneiden, die gegeneinander und hart aneinander vorbeigeführt werden, während das Blechstück, aus dem der zylindrische Stecker nach dem Scheren zusammengerollt wird, oder auch die Wandung des fertiggerollten Stekkers zwischen ihnen liegt. Auf diese Weise werden die Mantelflächenstücke des fertiggerollten Steckers oder die Stücke des ungerollten Bleches, die nachher beim gerollten Stecker die Mantelflächenstücke bilden, geschlitzt, ohne daß dabei Material verlorengeht. Auf diese Weise wird beim Stauchen des fertiggerollten und geschlitzten Steckerstiftes eine genügend große federnde Wölbung der Mantelfläche erreicht, ohne daß die größte Schlitzbreite über das zulässige Maß hinausgeht.For this reason, according to the invention, the slots are made by cutting by means of scissors, so manufactured in such a way that there is no loss of material. This separation is done by two horizontal scissors cutting against each other and hard to move past each other, while the piece of sheet metal from which the cylindrical Plug is rolled up after shearing, or the wall of the finished rolled Stekkers lies between them. In this way, the lateral surface pieces of the finished-rolled connector or the pieces of the unrolled Sheet metal, which afterwards form the jacket surface pieces in the rolled connector, slotted without that material is lost in the process. In this way, when upsetting the finished rolled and slotted connector pin a sufficiently large resilient curvature of the lateral surface achieved without the largest slot width going beyond the permissible dimension.
