Description

Schaltelement mit Anschlußdrähten für gedruckte Schaltungen In Geräten mit einer stark zusammengedrängten gedruckten schmaltung müssen häufig Bauelemente (Widerstände und Kondensatoren) senkrecht eingebaut werden. Das Einsetzen derartiger Bauelemente und das Umbiegen der Drahtenden auf der Kupferseite der Platte, das erforderlich ist, um die Teile bis zum Löten in ihrer Lage zu halten, ist oft durch eng nebeneinanderliegende Teile behindert ; außerdem können durch die abgebogenen Enden beim Löten leicht Kurzschlüsse entstehen. Die Neuerung vermeidet diese Nachteile. Gemäß der NeuerunG werden die senkrecht in Löcher in der Isolierstoffplatte einzusteckenden Anschlußdrähte in der Nähe ihres Endes oder am Ende längs der Achse des Drahtes derart verschieden stark zusammengepreßt, daß ein flaches Stuck mit konusförmig verlaufenden, zum Teil über den Draht hinausragen- u den Seitenkanten entsteht, welches sich in das Loch zwar einstecken läßt, jedoch nicht hindurchgleitot. Durch den konusförmigen Teil halten sich die Bauteile im Befestigungsloch bis zum Tauchlötvorgang ohne Umbiegen der Drahtenden.Switching element with connecting wires for printed circuits In devices with a tightly packed printed circuit, components (resistors and capacitors) often have to be installed vertically. The insertion of such components and the bending of the wire ends on the copper side of the board, which is necessary to hold the parts in place until soldering, is often hindered by closely spaced parts; In addition, short circuits can easily occur due to the bent ends during soldering. The innovation avoids these disadvantages. According to the innovation, the connecting wires to be inserted vertically into holes in the insulating material are compressed to different degrees near their end or at the end along the axis of the wire so that a flat piece with conical, partly protruding beyond the wire u the side edges arise, which can be inserted into the hole, but not slide through. Due to the conical part, the components stay in the fastening hole until the dip soldering process without bending the wire ends.

Auch in dem folgenden Fall ist die Neuerung anwendbar. Nach den Vorschriften in Schweden müssen Schaltelemente, die sich z. B. bei einem Kurzschluß stark erhitzen können, mit einem Abstand von mindestens 1 cm oberhalb einer Isolienstoffplatte angeordnet werden, auf deren Unterseite sich meist eine gedruckte Schaltung befindet. Bisher hat man den erforderlichen Abstand von der Isolierstoffplatte durch Zwischenlegen z. B. von Asbest hergestellt. Eine andere Möglichkeit besteht nach einem früheren Vorschlag der Anmelderin darin, die Anschlußdrähte in der Nähe ihrer Enden zu einer als Auflage dienenden Schulter abzubiegen, um zu vermeiden, daß die in die Löcher in der Isolierstoffplatte eingesteckten Drähte so it hindurchgleiten, daß das Schaltelement auf der Isolierstoffplatte aufliegt. Die Neuerung bietet eine andere, einfachere Möglichkeit. Die Zeichnung zeigt Ausführungsbeispiele der Neuerung. In Fig. 1 ist das Schaltelement 1 senkrecht angeordnet. Die Drähte sind in der Nähe ihrer Enden in der beschriebene Weise flachgedrückt.The innovation is also applicable in the following case. Accordance with the provisions in Sweden, switching elements that are z. B. heat up strongly in the event of a short circuit with a distance of at least 1 cm above a sheet of insulating material are arranged, on the underside of which there is usually a printed circuit. So far you have the required distance from the insulating plate by inserting it z. B. made of asbestos. Another possibility is after an earlier one Proposal of the applicant, the connecting wires near their ends to a Bend the shoulder serving as a support to avoid getting into the holes Inserted wires in the insulating material slide through it so that the switching element rests on the insulating plate. The innovation offers a different, simpler one Opportunity. The drawing shows exemplary embodiments of the innovation. In Fig. 1 is the switching element 1 is arranged vertically. The wires are near their ends flattened in the manner described.

In Fig. 2 ist das Schaltelement liegend angeordnet. Links ist die Isolierstoffplatte angedeutet, in die das konusförmige Ende eingesteckt wird. Fig. 3 zeigt, wie der Draht 2 mit zwei Preßstempeln 3 und 4 zusammengedrückt wird. Oben wird der Draht stärker zusammenge- drückt, so daß er dort mehr nach der Seite ausweicht. Dadurch ergibt sich die Konusform.In Fig. 2, the switching element is arranged horizontally. The insulating material plate into which the conical end is inserted is indicated on the left. 3 shows how the wire 2 is connected to two press dies 3 and 4 is squeezed. At the top the wire is tightened presses, so that he evades there more to the side. This results in the cone shape.
