Description

Klemmen zum Anschließen elektrischer Leiter werden mit einem federnden Kontaktdruck ausgestattet, damit beim Nachgeben des Leiters immer ein ,bestimmter Kontaktdruck bestehenbleibt.Terminals for connecting electrical conductors are spring-loaded Contact pressure equipped so that when the conductor gives way, there is always a certain amount of pressure Contact pressure remains.

Es sind bereits Klemmen bekannt, welche aus einem Blechraum bestehen, in dem eine Mutter eine kurze Strecke verschiebbar angeordnet ist und in welchem sich das Gewinde für die Druckschraube befindet.There are already known clamps, which consist of a sheet metal space, in which a nut is slidable a short distance and in which the thread for the pressure screw is located.

Zwischen der Mutter und dem Gehäuse ist eine in Hochkantform gewickelte Schraubenblattfeder angeordnet, die meistens nu,r aus einem Gang besteht und dazu dient, dien Kontaktdruck aufzunehmen. Diese Art Federn hat den Nachteil, daß sie sich unter Umständen in dem Genwinde der Schraube verfangen können und die Druckschraube sich nicht mehr auf- und abschrauben läßt.Between the nut and the housing is an edgewise wound Arranged helical leaf spring, which mostly consists of only one gear and to it serves to take up the contact pressure. This type of springs has the disadvantage that they can get caught in the winch of the screw and the pressure screw can no longer be screwed on and off.

Erfindungsgemäß wird dieser Mangel dadurch beseitigt, daß die in Hochkantform hergestellte und mehrfach gewundene Blattfeder mit ihren beiden Enden hochkant auf .die Mutter und mit ihrem mittleren Teil ebenfalls hochkant gegen den Rahmen der Klemme drückt.According to the invention, this deficiency is eliminated in that the in portrait form manufactured and multiple wound leaf spring with both ends upright .the mother and with its middle part also upright against the frame of the Clamp presses.

In der Abb. i ist die Klemme im Längsschnitt dargestellt.In Fig. I the clamp is shown in longitudinal section.

Die Abb. 2 zeigt eine Draufsicht auf die Klemme, bei der das obere Teil des Rahmens weggeschnitten ist.Fig. 2 shows a top view of the clamp, in which the upper Part of the frame is cut away.

Die Abb. 3 stellt eine Seitenansicht der Klemme dar.Fig. 3 shows a side view of the clamp.

In den Abb. 4 und 5 ist die Feder der Klemme in einem größeren Maßstab gezeichnet.In Figures 4 and 5 the spring of the clamp is on a larger scale drawn.

In dem Rahmen i der Klemme ist die Mutter 2 in Richtung des Klemmendruokes einen kurzen Weg verschiebbar angeordnet. Die Schraube 3 greift in das Gewinde der Mutter 2 ein und tritt mit ihrem oberen Ende durch den Rahmen i hindurch.In the frame i of the clamp the nut 2 is in the direction of the clamp druokes arranged to be displaceable a short distance. The screw 3 engages in the thread of the Nut 2 and passes with its upper end through the frame i.

Die Feder 4 ist zwischen der Mutter 2 und dem Rahmen i eingebaut und nimmt. den Kontaktdruck auf, sobald das Druckstück der Klemme 5 auf den Anschlußdraht 6 drückt. Die Feder 4 ist mehrfach schlangenförmig gewunden und drückt mit ihren Enden 7 und 8 auf die Mutter 2. Der mittlere Teil 9 der Feder drückt gegen den oberen Boden der Klemme i. Dadurch, daß die Auflagestellen 7 und 8 der Feder sich nicht in unmittelbarer Nähe der Schraube befinden, können sich die Enden der Feder nicht mit der Schraube 3 verwickeln. Außerdem wird' durch die'gewundene Form der Feder noch erreicht, daß die Gesamtfederlänge erheblich größer werden kann als ,bei schraubenförmig gewundenen Federn.The spring 4 is installed between the nut 2 and the frame i and takes. the contact pressure as soon as the pressure piece of terminal 5 hits the connecting wire 6 presses. The spring 4 is wound several times in a serpentine manner and presses with her Ends 7 and 8 on the nut 2. The middle part 9 of the spring presses against the upper one Bottom of clamp i. Because the support points 7 and 8 of the spring are not are in the immediate vicinity of the screw, the ends of the spring cannot be entangle with screw 3. In addition, 'by the' sinuous shape of the spring achieved that the total length of the spring can be considerably greater than with helical coiled springs.

PATENTANSPRUCH: Klemme zum Anschließen elektrischer Leiter mit federndem Kontaktdruck, bei der eine hochkant gewundene Blattfeder, deren Federung in Richtung des Hochkantprofils wirkt, zwischen dem Rahmen der Klemme und der verschiebbaren Mutter der Klemmschraube angeordnet ist, dadurch gekennzeichnet, daß die mehrfach schlangenförmig gewundene Feder mit ihren beiden Enden hochkant auf die Mutter und mit ihrem mittleren Teil ebenfalls hochkant gegen den Rahmen der Klemme drückt. Claim: Terminal for connecting electrical conductors with resilient contact pressure, in which an edgewise coiled leaf spring, the springiness of which acts in the direction of the edgewise profile, is arranged between the frame of the terminal and the sliding nut of the clamping screw, characterized in that the spring coiled several times in a serpentine manner its two ends upright on the nut and with its middle part also upright against the frame of the clamp.
