Abstract
Die Erfindung bezieht sich auf eine Schaltkontaktanordnung (8) mit einem Kontaktträger (10), mit zumindest zwei Schaltkontakten (12), die an dem Kontaktträger (10) schwenkbar gelagert sind und die jeweils einen in seiner Querschnittsfläche verminderten Endabschnitt (41) zur Aufnahme zumindest eines Anschlussleiters (21) aufweisen, und mit zumindest einem ersten Distanzstück (26), dass zwischen benachbarten der Schaltkontakte (12) angeordnet ist. Die Erfindung bezieht sich weiterhin auf einen elektrischen Schalter (1) mit einer derartigen Schaltkontaktanordnung (8). DOLLAR A Um die Höhe der für die Schaltbewegungen der Schaltkontakte (12) erforderlichen Antriebskräfte zu senken, ist vorgesehen, dass ein Abschnitt (45) des ersten Distanzstückes (26) zwischen den Endabschnitten (41) der benachbarten Schaltkontakte (12) angeordnet ist und somit ein Verbiegen der Schaltkontakte im Bereich der Endabschnitte (41) verhindert.The invention relates to a switching contact arrangement (8) with a contact carrier (10), with at least two switching contacts (12) which are pivotally mounted on the contact carrier (10) and each having a reduced in its cross-sectional area end portion (41) for receiving at least a connection conductor (21), and with at least one first spacer (26) that is arranged between adjacent ones of the switching contacts (12). The invention further relates to an electrical switch (1) with such a switching contact arrangement (8). DOLLAR A In order to reduce the height of the required for the switching movements of the switching contacts (12) driving forces, it is provided that a portion (45) of the first spacer (26) between the end portions (41) of the adjacent switching contacts (12) is arranged and thus prevents bending of the switching contacts in the region of the end sections (41).

Bei
bekannten elektrischen Schaltern mit Schaltkontaktanordnungen dieser
Art, bei denen das Schwenklager der Schaltkontakte von einem Lagerbolzen
gebildet ist, ist zumindest ein erstes Distanzstück vorgesehen, dass zwischen
benachbarten der Schaltkontakte angeordnet ist, um die Schaltkontakte auf
vorgegebenem Abstand zu halten und damit ein Auffächern (Kippen)
der Schaltkontakte in Achsrichtung des Lagerbolzens aufgrund der
gegenseitigen Beeinflussung der an einem Kontaktträger gelagerten
Schaltkontakte oder aufgrund der gegenseitigen Beeinflussung der
an benachbarten Kontaktträgern gelagerten

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein Abschnitt des zumindest einen ersten Distanzstückes zwischen den Endabschnitten der benachbarten Schaltkontakte angeordnet ist. – Die neue Schaltkontaktanordnung verhindert – insbesondere bei großen Kurzschlussströmen, neben dem Auffächern (Kippen) der Schaltkontakte auch ein Verbiegen der Schaltkontakte im Bereich ihrer in der Querschnittsfläche verminderten Endabschnitte. Diese Maßnahme trägt zur weiteren Verbesserung der Reibverhältnisse und insbesondere zur Vermeidung einer Selbsthemmung der Schaltkontakte bei.These Task is inventively characterized solved, a portion of the at least one first spacer between the end portions of the adjacent switching contacts is arranged. - The new Switch contact arrangement prevents - in particular with large short-circuit currents, in addition the fan-out (Tilting) of the switch contacts also bending the switch contacts in the region of their reduced in the cross-sectional area end portions. This measure contributes to further improvement of the friction conditions and in particular for Avoidance of self-locking of the switching contacts at.
In bevorzugter Ausgestaltung der neuen Schaltkontaktanordnung ist vorgesehen, dass das zumindest eine erste Distanzstück sowie ein mit dem zumindest einen ersten Distanzstück verbundener Quersteg integrale Bestandteile eines Abstandshalters sind, wobei sich das zumindest eine Distanzstück in Richtung des Quersteges über die Schaltkontakte hinaus erstreckt. – Bei einer derartigen Ausgestaltung ist eine elastische Verformung der ersten Distanzstücke möglich, so dass ein Abscheren dieser ersten Distanzstücke von dem sie verbindenden Quersteg vermieden wird. In preferred embodiment of the new switch contact arrangement is provided that the at least one first spacer and one with the at least a first spacer connected crosspiece integral components of a spacer are, wherein the at least one spacer in the direction of the crosspiece on the Switching contacts also extends. - In such an embodiment is an elastic deformation of the first spacers possible, so that a shearing off of these first spacers from the transverse web connecting them is avoided.
Besonders gute Reibverhältnisse können erzielt werden, wenn der Abstandshalter aus isolierendem Kunststoff besteht.Especially good friction conditions can be achieved when the spacer made of insulating plastic consists.
Eine weitere bevorzugte Ausgestaltung der neuen Schaltkontaktanordnung sieht vor, dass zumindest zwischen zwei benachbarten der Schaltkontakte zusätzlich zu dem zumindest einen ersten Distanzstück zumindest ein ein als Einzelteil ausgebildetes zweites Distanzstück vorgesehen ist, wobei das zumindest eine zweite Distanzstück eine Durchgangsöffnung aufweist, die an einen als Schwenklager der Schaltkontakte dienenden Lagerbolzen angepasst ist, eine dem Kontaktträger gegenüberstehende äußere Stützfläche aufweist und in einer Ebene mit dem zumindest einen ersten Distanzstück liegt. – Diese Ausgestaltung kombiniert mit Vorteil die Verbesserung der Reibverhältnisse mit einer Verringerung der Durchbiegung des Lagerbolzens.A further preferred embodiment of the new switching contact arrangement provides that at least between two adjacent of the switch contacts additionally to the at least one first spacer at least one as a single part trained second spacer is provided, wherein the at least one second spacer a Through opening has, which serve as a pivot bearing of the switch contacts Bearing pin is adapted to have a contact carrier opposite outer support surface and in a plane with the at least one first spacer. - These Design combines with advantage the improvement of the friction conditions with a reduction in the deflection of the bearing pin.
Das zumindest eine zweite Distanzstück besteht vorzugsweise aus Stahlblech oder Messingblech.The at least a second spacer is preferably made of sheet steel or brass sheet.
