Abstract
Description
Die Erfindung betrifft ein elektrisches Schaltgerät gemäß dem Oberbegriff des Anspruches 1.The The invention relates to an electrical switching device according to the preamble of the claim 1.
Insbesondere betrifft die Erfindung ein Schaltwerk mit einer Verklinkungsstelle, mit einem Kontakthebel, der über eine Lasche und ein Kupplungselement mit einem Schaltknebel verbunden ist, wobei bei Verschwenkung des Schaltknebels in Einschaltrichtung der Kontakthebel über das Kupplungselement und die Lasche bei verklinkter Verklinkungsstelle in Einschaltstellung verbracht wird, für ein elektrisches Schaltgerät.Especially the invention relates to a rear derailleur with a latching point, with a contact lever that over a tab and a coupling element connected to a switch knob is, wherein when pivoting the switch knob in the switch-on the contact lever over the coupling element and the tab with latched Verklinkungsstelle is spent in closed position, for an electrical switching device.
Bei einer Einschaltung eines derartigen Schalters, der beispielsweise als Schalter S2 der Firma ABB Stotz Kontakt GmbH, Heidelberg, bekannt geworden ist, verläuft die Einschaltbewegung des Kontakthebels mit einer der Geschwindigkeit der Betätigung des Schaltknebels entsprechenden Einschaltgeschwindigkeit. Insbesondere bei Einschalten auf Last kann dies dazu führen, dass kurz vor der Berührung des beweglichen Kontakthebels mit dem feststehenden Kontakthebel ein Lichtbogen entsteht, der zur Beschädigung der Kontaktstelle führen kann.at an activation of such a switch, for example known as switch S2 of the company ABB Stotz contact GmbH, Heidelberg is, runs the switch-on movement of the contact lever at one of the speeds the operation the switching knob corresponding switch-on speed. Especially When switched on on load, this can lead to the fact that just before the touch of the movable contact lever with the fixed contact lever Arc is created, which can lead to damage to the contact point.
Aufgabe der Erfindung ist es, ein Schaltgerät der eingangs genannten Art zu schaffen, bei dem derartige Lichtbögen im wesentlichen verhindert oder doch auf ein geringes Maß reduziert sind.task The invention is a switching device of the type mentioned to provide, in which such arcs substantially prevented or reduced to a low level are.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.These The object is achieved by the Characteristics of claim 1 solved.
Danach sind Mittel zum zeitweisen Festhalten des beweglichen Kontaktstückes während des Einschaltvorganges vorgesehen, die bei Weiterbewegen des Kontakthebels freigegeben werden, so dass ein plötzliches Auftreffen des beweglichen Kontaktstückes auf das feste Kontaktstück bewirkt wird.After that are means for temporarily holding the movable contact piece during the switch-on provided that released upon further movement of the contact lever so be a sudden Impact of the movable contact piece causes the fixed contact piece becomes.
Damit wird der Einschaltvorgang zumindest in der Zeit, in der ein Lichtbogen entstehen kann, stark beschleunigt.In order to the turn-on is at least in the time in which an arc can arise, greatly accelerated.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist als Mittel ein Doppelarmhebel vorgesehen, dessen einer Arm mit dem das Kontaktstück aufweisenden Ende des Kontakthebels, dieses zeitweise verrastend, und dessen anderer Arm von dem Kontakthebel bei dessen Einschaltung betätigt wird, so dass der eine Arm den Kontakthebel freigibt.According to one advantageous embodiment of the invention is as a means a Doppelarmhebel provided, one arm having with the contact piece End of the contact lever, temporarily latching this, and its other arm is actuated by the contact lever when it is switched on, so that one arm releases the contact lever.
Bei einer ersten Ausführungsform befindet sich der Drehpunkt des Doppelarmhebels auf der dem feststehenden Kontaktstück entgegen gesetzt liegenden Seite des Kontakthebels, wobei der andere Arm mit dem Hebelbereich zusammenwirkt, an dem die Lasche angreift.at a first embodiment is the pivot point of the double-arm lever on the fixed contact piece opposite side of the contact lever, the other Arm cooperates with the lever area, which engages the tab.
Erfindungsgemäß kann der Doppelarmhebel zwei Arme aufweisen, die senkrecht zueinander verlaufen, wobei das freie Ende des einen Armes sich im Bereich der Lagerstelle des Kontakthebels befindet, wogegen der andere Arm einen in den Bewegungsweg des Kontakthebels hineinragenden Vorsprung aufweist, der den Kontakthebel während des Einschaltvorganges wenigstens zeitweise festhält.According to the invention of Double Arm have two arms that are perpendicular to each other, the free end of the one arm being in the area of the bearing the contact lever is, whereas the other arm in the Movement path of the contact lever protruding projection, the contact lever during the switch-on at least temporarily holds.
Dabei kann an dem Vorsprung auf der dem Kontakthebel benachbarten Seite eine ebene Fläche vorgesehen sein, gegen die eine Nase am Kontakthebel während des Ein schaltvorganges anliegt, wobei die Fläche so bemessen ist, dass nach Zurücklegen eines bestimmten Drehwinkels der Vorsprung den Kontakthebel freigibt.there may be at the projection on the side adjacent to the contact lever a flat surface provided be, against the nose on the contact lever during the one switching operation is applied, the area is sized so that after returning a certain angle of rotation of the projection releases the contact lever.
Durch diese erste Maßnahme wird auf einfache Weise ein sogenanntes Einschalt-Spungschaltwerk erzeugt.By this first measure In a simple way, a so-called switch-on SPF is generated.
Bei einer zweiten Ausgestaltung der Erfindung befindet sich der Drehpunkt des Doppelarmhebels zwischen dem beweglichen Kontaktstück und der Ebene, die durch die Senkrechte auf die Befestigungsebene des Schaltgerätes, die durch das feststehende Kontaktstück verläuft und senkrecht zu den Seitenwandflächen des Gehäuses ausgerichtet ist, wobei der eine Arm des Kontakthebels mit einem Vorsprung gegen die Kontaktstückseite gekantetes Kontakthebels im Bereich des Langloches gegen diesen anliegt, wogegen der andere Arm des Doppelarmhebels mit dem Ende des Kontakthebels zusammenwirkt, an dem sich das bewegliche Kontaktstück befindet.at a second embodiment of the invention is the fulcrum of the double-arm lever between the movable contact piece and the Plane, which is defined by the vertical to the mounting plane of the switching device, the through the fixed contact piece extends and aligned perpendicular to the side wall surfaces of the housing is, wherein the one arm of the contact lever with a projection against the contact piece side edged contact lever in the region of the slot against this is present, whereas the other arm of the double-armed lever with the end the contact lever cooperates, on which the movable contact piece is located.
Weitere vorteilhafte Ausgestaltungen der Erfindung sowie weitere Verbesserungen sind den weiteren Unteransprüchen zu entnehmen.Further advantageous embodiments of the invention and further improvements are the further subclaims refer to.
Anhand der Zeichnung, in der zwei Ausführungsbeispiele der Erfindung dargestellt sind, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen der Erfindung näher erläutert und beschrieben werden.Based of the drawing, in the two embodiments the invention are shown, the invention and others advantageous embodiments of the invention will be explained and described in detail.
