Description
Es gibt Klemmen zum Anschließen elektrischer Leitungen, bei denen ein über eine Schiene gleitender beweglicher Klemmbügel benutzt wird und zwischen Schiene und Klemmbügel eine Blattfeder den Kontaktdruck überträgt, damit der angeschlossene Leiter bei Temperaturschwankungen oder sonstigen Veränderungen im Material mit dem gleichen Kontaktdruck festgehalten wird. Die bereits für eine Druckübertragung ,bekannten Blattfedern sind für die Benutzung in Klemmen, wie sie z. B. in kleinen gekapselten Gehäusen, Anlagen oder Geräten Verwendung finden, nicht geeignet, da ihre Wirkung in bezug auf ihre Größe und Gestaltung zu gering ist. Damit die Blattfeder einen genügend großen Kontaktdruck ausüben kann, ist sie erfindungsgemäß wellenförmig gebogen und besitzt mehrere Wellen, so daß sie an -mehreren Stellen gleichzeitig den Druck überträgt. .There are terminals for connecting electrical lines where a movable clamping bracket sliding over a rail is used and between Rail and clamp a leaf spring transmits the contact pressure so that the connected Conductor in the event of temperature fluctuations or other changes in the material with the the same contact pressure is held. The ones already known for a pressure transmission Leaf springs are for use in clamps such as those found in US Pat. B. in small encapsulated Enclosures, systems or devices are not suitable because of their effect is too small in terms of size and design. So that the leaf spring one can exert a sufficiently large contact pressure, according to the invention it is wavy curved and has several waves, so that they are in several places at the same time transfers the pressure. .
Ein weiteres Merkmal der Erfindung besteht noch darin, daß in der Schiene an der Druckplatte oder an dem Klemmbügel kleine muldenförmige Vertiefungen vorhanden sind, die den einzelnen Wellen der Blattfeder als Führung dienen.Another feature of the invention is that in the Rail on the pressure plate or on the clamping bracket small trough-shaped depressions are available, which serve as a guide for the individual waves of the leaf spring.
Erfindungsgemäß kann die Blattfeder auch als Federmagazin ausgebildet sein, d. h. es sind mehrere Blattfedern zur Erhöhung des Kontaktdruckes aufeinandergeschichtet. Als seitliche Führung für die Blattfeder, die mit ihren wellenförmigen Teilen an dem Klemmbügel und an der Schiene aufliegt, dienen von der Schiene bzw. von dem Druckstück abgebogene Lappen. Bei der Verwendung von zwei Klemmen auf einer gemeinsauren Schiene wird als weiteres Erfindungsmerkmal auch eine gemeinsame wellenförmige Feder benutzt.According to the invention, the leaf spring can also be designed as a spring magazine be, d. H. several leaf springs are stacked to increase the contact pressure. As a lateral guide for the leaf spring, which starts with its wave-shaped parts the clamp and rests on the rail, are used by the rail or by the Pressure piece bent rag. When using two clamps on one joint Rail is also a common wave-shaped spring as a further feature of the invention used.
Die Abb. i und 2 zeigen eine Klemme, bei der die Feder i unterhalb der Anschlußschiene 2 angeordnet ist. Das anzuschließende Kabel 3 wird zwischen der Anschlußschiene 2 und der Druckplatte q. eingeklemmt. Die Schraube 5 dient zum Anziehen der Druckplatte.Figs. I and 2 show a clamp with the spring i underneath the connecting rail 2 is arranged. The cable to be connected 3 is between the connecting rail 2 and the pressure plate q. trapped. The screw 5 is used to Tightening the pressure plate.
Die Abb.3@ und q. zeigen die Anordnung der Druckfeder i zwischen der Anschlußschiene 2 und der Druckplatte q..The Fig.3 @ and q. show the arrangement of the compression spring i between the Connecting rail 2 and the pressure plate q ..
Die Abb. 5 stellt eine doppelte Klemme dar, bei der die beiden Klemmbügel io und i i auf einer gemeinsamen Schiene i2 befestigt sind und bei der auch eine gemeinsame wellenförmige Feder 15 Anwendung findet.Fig. 5 shows a double clamp in which the two clamps io and i i are fastened on a common rail i2 and in which also a common wave-shaped spring 15 is used.
Die Druckfeder i ist als Blattfeder ausgebildet und besitzt erfindungsgemäß eine wellenförmige Gestalt. Um sie elastisch zu machen oder auch ihren Druck zu erhöhen, kann sie aus mehreren Einzelblättern zu einem Magazin zusammengesetzt sein. Damit die Druckfeder nicht verlorengehen kann und auch gleichmäßig aufliegt, wird sie beispielsweise in Vertiefungen 9 der Anschlußschiene 2 oder des Druckstückes q. oder des Klemmbügels selbst gehalten. Auf diese Weise erhält die Druckfeder eine gewisse Führung. Eine weitere Führung der Feder besteht noch darin, daß die Anschlußschiene 2 am vorderen Ende mit einem abgebogenen Winkel 6 versehen ist, welcher ein Herausschieben der Druckfeder i verhindert. Eine gleiche Anordnung wird auch bei der Klemme nach Abb. 5 dadurch erreicht, daß die Druckschiene 13 .The compression spring i is designed as a leaf spring and has according to the invention a wavy shape. To make them elastic or to tighten their pressure increase, it can be composed of several single sheets to form a magazine. So that the compression spring cannot be lost and also rests evenly they for example in recesses 9 of the connecting rail 2 or the pressure piece q. or held by the clamp itself. In this way, the compression spring receives a certain guidance. Another guide of the spring is that the connecting rail 2 is provided at the front end with a bent angle 6, which a sliding out the compression spring i prevents. The same arrangement is also used for the terminal Fig. 5 achieved in that the pressure rail 13.
die abgebogenen Winkel 1q. besitzt. Bei Einbau der Klemme in einen Apparat wird der Klemmbügel 7 so nahe au die Wand des Sockels 8 gesetzt, daß auch nach dieser Seite die Druckfeder i nicht herausrutschen kann. Falls es nicht möglich ist, die Klemme so nahe an den Sockel zu bringen, kann die Schiene 2 an beiden Enden wie bei der Klemme nach Abb. 5 abgebogen werden. Ein Herausfallen der Feder ist dann ebenfalls nicht möglich.the bent angles 1q. owns. When installing the clamp in a Apparatus, the clamping bracket 7 is set so close to the wall of the base 8 that also on this side the compression spring i cannot slip out. If not possible is to bring the clamp so close to the base, the rail 2 can be at both ends be bent as with the clamp according to Fig. 5. The spring is falling out then also not possible.
