Description

Starkstromklemme Es sind Starkstromklemmen bekannt, die aus zwei massiven, mit einem Klemmnutenpaar für die Leiter verschenen Klemmbacken bestehen, die zwischen zwei den Schwundausgleich bewirkenden Federplatten angeordnet und durch mittig angeordnete Schraubenbolzen verklemmbar sind. Gegenstand der Erfindung ist eine StarkstromMemme solcher Art, welche sich von den bekannten Ausführungen gemäß, der Erfindung dadurch unterscheidet, daß die federnden Platten zwei nach verschiedenen Richtungen verlaufende Wölbungen, nämlich eine Quer- und Längswölbung besitzen und die Schraubenbolzen im Scheitel der Wölbungen sitzen.Power clamps Power clamps are known which consist of two massive clamping jaws, with a pair of clamping grooves for the conductors, which are arranged between two spring plates which compensate for shrinkage and which can be clamped by centrally arranged screw bolts. The subject of the invention is a heavy current terminal of this type, which differs from the known designs according to the invention in that the resilient plates have two curvatures extending in different directions, namely a transverse and longitudinal curvature, and the screw bolts sit in the apex of the curvatures.

Während also bei den bisherigen Starkstromklemmen die Federplatten quer gewölbt sind, wird durch die Doppelwölbung gemäß der Erfindung auf einfache und praktische Weise ein allseitiger Spannungsausgleich auf die ganze Fläche der Platte und damit eine gute Kontakthaltung erreicht.While the spring plates were used in the previous high-voltage terminals are curved transversely, is made easy by the double curvature according to the invention and in a practical way, an all-round equalization of tension on the entire surface of the Plate and thus good contact retention is achieved.

Ein Ausführungsbeispiel der Erfindung ist in Abb. 1 im Längsschnitt nach der Linie V-V von Abb. 2 und in Abb. 2 in Stirnansicht im großen Maßstab gezeigt. Auf der durchgehenden Oberbacke a und den beiden Unterbacken b (s. Abb. 1) liegt je eine Federplatte c unverspannt auf, die nicht nur nach dem Profil der Klemmbacken a, b quer gewölbt, sondern auch der Länge nach leicht gewellt ist, und zwar so, daß die Klemmschrauben d jeweils im Scheitel angreifen, während ein Wellental in der Mitte zwischen beiden Schraubend und an den Enden der Klemmbacken a, b zur Auflage kommt. Dabei sei betont, daß die Wellung in der Zeichnung der Deutlichkeit halber größer ausgeführt ist als in Wirklichkeit. Die Wellung beträgt zweckmäßig nur Bruchteile von Millimetern.An embodiment of the invention is shown in Fig. 1 in longitudinal section along the line VV of Fig. 2 and in Fig. 2 in a front view on a large scale. On the continuous upper jaw a and the two lower jaws b (s. Fig. 1) is, depending on a spring plate c to unstressed, not only by the profile of the clamping jaws a, b transversely arched, but also the length is corrugated by light, namely so that the clamping screws d each attack in the apex, while a wave trough in the middle between the two screws and at the ends of the clamping jaws a, b comes to rest. It should be emphasized that the corrugation in the drawing is made larger for the sake of clarity than in reality. The corrugation is expediently only fractions of a millimeter.

Beim Verspannen der Schraubend legt sich ein Wellental der Federplatten c zunächst mit Vorspannung auf die mittlere Zone zwischen den Schraubend und auf die Klemmenden. Werden die Schraubend weiter angezogen, so werden schließlich die Federplatten c vollkommen anliegend auf die Klemmbacken a bzw. b gepreßt.When the screw is tightened, a trough of the spring plates c is initially placed with prestress on the middle zone between the screw and on the clamping ends. If the screw is tightened further, the spring plates c are finally pressed completely against the clamping jaws a and b .

Die Kombination einer Querwölbung mit einer Längswellung ergibt eine außerordentlich hohe Federsteifigkeit, die in Verbindung mit der Vorspannung genügt, um den Anpreßdruck in der mittleren Zone zwischen den Schraubend dem in der Nähe der Aufpreßstellen herrschenden anzugleichen, so daß somit eine vollkommen gleichmäßige Druckverteilung auf die Backen a, b und damit auch auf die Leiter e innerhalb der gesamten Klemmlänge erzielt ist.The combination of a transverse curvature with a longitudinal corrugation results in an extraordinarily high level of spring stiffness, which, in conjunction with the preload, is sufficient to equalize the contact pressure in the middle zone between the screw ends with that in the vicinity of the press-on points, so that a completely even pressure distribution on the jaws a, b and thus also on the conductor e is achieved within the entire clamping length.
