Abstract
Description
Die Erfindung betrifft eine Federzugklemme gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a spring clamp according to the preamble of the claim 1.
Federzugklemmen werden zum schraubenlosen Anschluss von Anschlussleitern an elektrische Installationsschaltgeräte, beispielsweise Leitungsschutzschalter, Motorschutzschalter oder Leistungsschalter, eingesetzt. Sie sind üblicherweise in gesonderten Klemmenanschlussräumen in den Gehäusen der Installationsgeräte eingesetzt. Sie umfassen üblicherweise eine Klemmfeder, welche einen Anlageschenkel, einen Klemmschenkel mit einer Klemmkante und einen den Anlage – und Klemmschenkel verbindenden gebogenen Federrücken umfasst, und die mit einem eine Stromschiene mit einem Klemmstreifen umfassenden Trägerteil so zusammenwirkt, dass der Anschlussleiter zwischen der Rückseite des Klemmstreifens und einer Kante des Klemmfensters anklemmbar istspring-loaded terminals are used for screwless connection of connecting conductors to electrical installation switching devices, for example Circuit breaker, motor protection switch or circuit breaker, used. They are usually in separate terminal connection spaces in the cases of the installation equipment used. They usually include a clamping spring which a plant leg, a clamping leg with a clamping edge and a connecting and clamping leg curved spring back includes, and the one with a bus bar with a clamping strip comprehensive carrier part so cooperates that the connecting conductor between the back the clamping strip and an edge of the clamping window clamped is
Aus
der
Um
Abhilfe zu schaffen, ist es im Stand Technik, beispielsweise in
der
Es wurde auch vorgeschlagen, Anschlagkanten für den Anschlussleiter im Bereich des Klemmenanschlussraumes in die Gehäusewand zu integrieren. Die Schaltgerätegehäuse werden in der Regel im Spritzgießverfahren hergestellt. Bei bestimmten Gehäuseformen und Anordnungen des Klemmenanschlussraumes im Gehäuse gibt es dann Schwierigkeiten, die Anschlagskante in einem Gießvorgang mit herzustellen, da die Anschlagskanten so angebracht werden müssten, dass keine Entformmöglichkeit beim Spritzgießen besteht.It It has also been proposed to have stop edges for the connection conductor in the area to integrate the terminal connection space in the housing wall. The Switchgear housings are usually by injection molding produced. For certain housing types and arrangements of the terminal connection space in the housing there it then difficulties the stop edge in a casting process with, since the stop edges would have to be mounted so that no demoulding possibility in injection molding consists.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine gattungsgemäße Federzugklemme so weiterzuentwickeln, dass ohne zusätzlichen Aufwand bei der Montage und unabhängig von der Gehäuseform oder der Anordnung des Klemmenanschlussraumes im Gehäuse ein zu tiefes Einführen des Anschlussleiters in die Federzugklemme verhindert wird.It is therefore the object of the present invention, a generic spring clamp further develop that without additional effort during assembly and independent from the housing shape or the arrangement of the terminal connection space in the housing too deep insertion of the Connecting conductor is prevented in the spring-loaded terminal.
Die Aufgabe wird erfindungsgemäß gelöst durch eine gattungsgemäße Federzugklemme mit den kennzeichnenden Merkmalen des Anspruchs 1.The The object is achieved by a generic spring clamp with the characterizing features of claim 1.
Erfindungsgemäß also ist an dem Trägerteil einstückig ein Stützstreifen mit einem Anschlagschenkel angeformt und bezogen auf die Rückseite des Klemmstreifens so angeordnet, dass durch den Anschlagschenkel eine Anschlagsfläche für den Anschlussleiter gebildet ist, die ein zu tiefes Eindringen des Anschlussleiters in die Federzugklemme verhindert.Thus, according to the invention on the support part in one piece support strips formed with a stop leg and based on the back of the Clamping strip arranged so that through the stop leg a stop surface for the Terminal conductor is formed, which is too deep penetration of the connecting conductor prevented in the spring clamp.
Der Vorteil einer erfindungsgemäßen Federzugklemme liegt darin, dass das Trägerteil als einheitliche Baugruppe erfindungsgemäß vorgebogen werden kann, so dass die Anschlagfläche, welche ein zu tiefes Eindringen des Anschlussleiters in die Federzugklemme verhindert, als integraler Bestandteil des Trägerteiles einstückig mit diesem verbunden ist, so dass kein separates Anschlagteil erforderlich ist. Das vorgebogene Trägerteil kann zusammen mit der Klemmfeder in jeden beliebig gestalteten Klemmenaufnahmeraum eines Installationsschaltgerätes eingesetzt werden; es ist bei dem Einsatz der erfindungsgemäßen Federzugklemme keine Rücksichtnahme auf gestaltungsbedingte Entformmöglichkeiten im Zuge des Spritzgussprozesses erforderlich.Of the Advantage of a spring-loaded terminal according to the invention lies in the fact that the carrier part can be vorgebogen as a unitary assembly according to the invention, so that the stop surface, which is too deep penetration of the connecting conductor in the spring clamp prevented, as an integral part of the support member in one piece with this is connected, so that no separate stop member required is. The pre-bent carrier part can together with the clamping spring in any arbitrarily designed terminal receiving space an installation switching device be used; it is in the use of spring clamp according to the invention no consideration on design-related Entformmöglichkeiten required in the course of the injection molding process.
