Description
Es sind Zylinderkontakte bekannt, bei welchen mehrere Kontaktsegmente um einen zylindrischen Kontaktbolzen angeordnet sind. Beim Unterbrechen großer Stromstärken werden durch die Einwirkungen des Lichtbogens die aneinanderliegenden Segmente zusammengeschweißt, und es wird dadurch schließlich die Beweglichkeit dieser Segmente vollständig aufgehoben, wodurch die ganze Kontaktvorrichtung unbrauchbar wird.There are cylinder contacts known in which several contact segments around one cylindrical contact pins are arranged. When interrupting large currents the adjacent segments are welded together by the effects of the arc, and the mobility of these segments is thereby finally completely abolished, whereby the entire contact device becomes unusable.
Der Erfindungsgegenstand behebt diese Mängel dadurch, daß die einzelnen Kontaktsegmente voneinander distanziert und an der Abreißstelle die Kanten der einzelnen Seg-IS mente derart abgeschrägt sind, daß allfällige Schweißstellen die Segmente nicht zusammenschweißen können. The subject matter of the invention eliminates these deficiencies in that the individual contact segments distanced from each other and at the tear-off point the edges of the individual Seg-IS elements are bevelled in such a way that any welds cannot weld the segments together.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in einem Längsschnitt (Abb. 1) und Draufsicht (Abb. 2) dargestellt.In the drawing, an embodiment of the subject matter of the invention is in one Longitudinal section (Fig. 1) and top view (Fig. 2) shown.
Die in Abb. 1 dargestellten Zylinderkontaktsegmente 2 befinden sich in der normalen Kontaktlage. Es bedeutet 1 den Kontaktbolzen, 3 eine Ringfeder, welche samtliehe Kontaktsegmente an* den Kontaktbolzen 1 anpreßt. 4 und 5 bedeuten Schweißperlen an den Abreißstellen des Ausschaltlichtbogens. Die strichpunktiert gezeichnete Lage nehmen die Kontaktsegmente ein, wenn an den Abreißstellen solche Schweißpunkte auftreten. Dadurch kippen die Segmente unter dem Druck der Feder 3 um die Auflagepunkte 6, wodurch der spezifische Kontaktdruck derart erhöht wird, daß die Verluste durch Stromwärme praktisch dieselben blei-The cylinder contact segments 2 shown in Fig. 1 are in the normal Contact position. It means 1 the contact pin, 3 an annular spring, which together Contact segments on * the contact pin 1 presses on. 4 and 5 represent welding beads at the break-off points of the switch-off arc. The position shown in dash-dotted lines is taken by the contact segments when such weld points occur at the tear-off points. As a result, the segments tilt under the pressure of the spring 3 about the support points 6, whereby the specific contact pressure is increased in such a way that the losses due to current heat remain practically the same.
ben wie in der normalen Kontaktlage. Diese Kontaktvorrichtung vereinigt in sich also den Haupt- und den Äbfeißkontäkt. Der Kontaktbolzen ι nimmt in der normalen Kontaktstellung eine solche Lage ein, daß seine etwaigen Brandstellen außer Bereich der Kontaktsegmente Hegen.practice as in the normal contact position. This contact device thus combines the Main and the Äbfeißkontäkt. The contact pin ι takes in the normal contact position such a position that its possible burns outside the area of the contact segments Cherish.
Um das seitliche Anschweißen der Segmente unter sich zu vermeiden, sind letztereIn order to avoid the side welding of the segments under each other, the latter are
ίο mit Ansätzen 7 (Abb. 2) versehen, welche die Segmente voneinander distanzieren und gegenüber den Segmentkontaktflächen zurückstehen. Zum selben Zweck sind die Segmente seitlich an ihren Kanten wenigstens an den Abreißstellen abgeschrägt, damit die Schweißstellen die Segmente nicht überbrücken können. Die Ringfeder 3 wird zweckmäßig so angeordnet, daß sie ungefähr in der Mitte des durch Schweißung geschaffenen neuen Berührungspunktes und der Auflage 6 liegt, um an diesen beiden Stellen ungefähr dieselbe Drucksteigerung zu erzielen. Einerseits wird damit erreicht, daß sich die Brandstellen rasch wieder blank schleifen, anderseits wird am Auflagepunkt der Übergangswiderstand herabgesetzt. ίο provided with lugs 7 (Fig. 2), which the Separate the segments from one another and stand back from the segment contact surfaces. For the same purpose, the segments are laterally at their edges at least at the tear-off points beveled so that the welds cannot bridge the segments. The ring spring 3 is expediently so arranged that they are approximately in the middle of the new contact point created by welding and the support 6 is to approximately the same pressure increase at these two points to achieve. On the one hand it is achieved that the burns quickly sand themselves bright again, on the other hand it is The contact point of the contact resistance is reduced.
