Description

Starkstromklemme Es sind Starkstromklemmen bekannt, welche aus zwei massiven Klemmbacken bestehen, die mindestens mit einer Federplatte aus einem Werkstoff höherer Festigkeit als die Klemmbacken versehen und durch mittig angeordnete Schraubenbolzen verklemmbar sind.Power clamp There are power clamps known, which consist of two There are massive clamping jaws that are made of at least one material with a spring plate higher strength than the clamping jaws and provided by centrally located screw bolts are jammed.

Gegenstand der Erfindung ist eine Starkstromklemme, bei welcher, gemäß der Erfindung, der Druck der Federplatte durch -einen auf die ganze Länge derselben sich erstreckenden, die Muttergewinde der Schraubenbolzen enthaltenden, lose aufgesetzten Steg auf die Klemmbacken übertragen wird.The invention relates to a power terminal in which, according to of the invention, the pressure of the spring plate by -ein on the entire length of the same extending, containing the nut threads of the screw bolts, loosely fitted Web is transferred to the jaws.

Die durch die Vereinigung der Federplatten mit einem Drucksteg gegebenen Vorteile sind mannigfacher Art, indem durch den Steg ein gleichmäßiger Längsdruck auf die Federplatte ausgeübt wird, wodurch ein in der Längsrichtung der Platte mögliches Aufbiegen an den Rändern vermieden wird. Ferner ergibt sich eine Vereinfachung der Montage der Klemme, weil ein Gegenhalten der üblichen Gegenmutter wegfällt, und schließlich kann der Drucksteg der Spannkraft der Federplatte oder der Größe der Klemme ohne weiteres angepaßt oder ausgewechselt und eine Druckübertragung des Steges auch bei im Winkel stehenden Abzweigklemmen erreicht werden, was für einen, auf die Dauer wirkenden guten Kontakt wichtig ist.The given by the union of the spring plates with a pressure bar The advantages are manifold, in that the web creates a uniform longitudinal pressure is exerted on the spring plate, whereby a possible in the longitudinal direction of the plate Bending up at the edges is avoided. Furthermore, there is a simplification of the Assembly of the clamp, because there is no counter-holding of the usual counter nut, and Finally, the pressure bar can be the clamping force of the spring plate or the size of the Clamp easily adapted or replaced and a pressure transmission of the web can also be achieved with branch clamps standing at an angle, what a, on the long-term effective contact is important.

Ein Ausführungsbeispiel der Erfindung ist in Abb. 1 der Zeichnung in Stirnansicht, in Abb. 2 im Schnitt und in Abb. 3 in Untersicht dargestellt.An embodiment of the invention is shown in Fig. 1 of the drawing in a front view, in Fig. 2 in section and in Fig. 3 in a bottom view.

In den Abb. 1 und 2 ist die dem Drucksteg zugeordnete Federplatte im montierten Zustand der Klemme veranschaulicht, in welchem sie nicht vollständig angepreßt ist, um den notwendigen Federweg zur Verfügung zu haben.In Figs. 1 and 2, the spring plate associated with the pressure bar is illustrated in the assembled state of the clamp, in which it is not fully pressed in order to have the necessary spring travel available.

Die Federplatte b liegt auf der Unterbacke d auf und ist nach dem Profil dieser Backe quer verwölbt. Die obere Federplatte a der Backe c kann gewölbt sein, steht jedoch nicht in Verbindung mit der Erfindung.The spring plate b rests on the lower jaw d and is curved transversely according to the profile of this jaw. The upper spring plate a of the jaw c can be curved, but is not related to the invention.

Die die Backen a, b zusammenpressenden Klemmschrauben e haben ihr Muttergewinde f im Druckstegg, der sich über die ganze Länge der Federplatte erstreckt. Der Drucksteg g ist dabei so stark ausgebildet, daß er trotz der großen Belastung durch die Schrauben e praktisch keine Durchbiegung erfährt.The clamping screws e pressing the jaws a, b together have their nut thread f in the pressure bar, which extends over the entire length of the spring plate. The pressure web g is made so strong that it experiences practically no deflection despite the great load from the screws e.

Auf diese Weise wird die Kraft der Klemmschrauben e gleichmäßig über die ganze Länge der Federplatte b, also auch auf die Zone zwischen den beiden Gewindenf übertragen. Dadurch wird eine vollkommen gleichmäßige Druckverteilung auf die Backen a, b und damit auch auf die Leiter h innerhalb der gesamten Klemmlänge erzielt.In this way, the force of the clamping screws e is transmitted evenly over the entire length of the spring plate b, i.e. also to the zone between the two threads f. As a result, a completely even pressure distribution on the jaws a, b and thus also on the ladder h is achieved within the entire clamping length.
