Abstract
Description
Die Erfindung bezieht sich auf eine Federkraftklemme gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to a spring-loaded terminal according to the features of the preamble of claim 1.
In
bekannter Ausführung
weisen solche Federkraftklemmen eine Klemmfeder in Gestalt einer Kastenfeder
auf, bei der aus der einen Wandung der Klemmschenkel herausgestellt
ist und die dem Klemmschenkel gegenüberliegende Kastenwandung das
Klemmwiderlager bildet, zu dem hin der Klemmschenkel vorgespannt
ist; vergleiche hierzu
Bei Kastenfedern der genannten Art ist für Aufbringung der Federkraft des Klemmschenkels zum einen dessen Länge und zum anderen der zur Verfügung stehende Weg für die Auslenkung des Klemmschenkels beim Klemmen eines Leiters maßgebend. Beide Kriterien hängen von den Dimensionen der jeweiligen Kastenfeder ab, wobei vor allem die Länge bzw. Breite derjenigen Kastenwandung, aus der der Federschenkel herausgestellt ist, dessen Länge begrenzt. Andererseits bietet die Kastenfeder den Vorzug, darin einen Drücker zum Spreizen des Klemmschenkels vom gegenüberliegenden Klemmwiderlager weg gut unterbringen zu können. Dadurch sind der Miniaturisierung der mit Kastenfedern ausgestatteten Federkraftklemmen insbesondere dann Grenzen gesetzt, wenn es um die Aufrechterhaltung einer ausreichenden Federkraft zum Klemmen der Leiter geht.at Box springs of the type mentioned is for application of the spring force the clamping leg on the one hand its length and on the other hand the available Way for the deflection of the clamping leg when clamping a conductor prevail. Both criteria depend from the dimensions of the respective box spring, especially the Length or Width of the box wall, made out of the spring legs is whose length limited. On the other hand, the box spring offers the advantage in it a pusher for spreading the clamping leg from the opposite clamping abutment to be able to accommodate well. As a result, the miniaturization of equipped with box springs Spring clamps in particular then limits when it comes to maintaining a sufficient spring force for clamping the leader leaves.
Weiterhin
sind Klemmfedern für
Federkraftklemmen bekannt, die eine Schlaufenform aufweisen, bei
welcher der Klemmschenkel zum Anlageschenkel hin zurückgebogen
ist; vergleiche JP 07-022084 A,
Der zwischen dem Klemmschenkel und dem Anlageschenkel liegende Rückenbereich der schlaufenfördmigen Klemmfedern bietet bezogen auf die Dimension der jeweiligen Klemmfeder einen längeren Weg, über den hinweg sich der Biegebereich erstreckt und sich die Federspannung aufbaut. Dies führt zu einer günstigeren Verteilung der mechanischen Spannungen, woraus eine dementsprechend höhere Federkraft resultiert. Jedoch weisen die mit den schlaufenförmigen Klemmfedern ausgestatteten Federkraftklemmen Drücker zum Aufheben der Klemmkraft nicht auf, schon gar nicht ist bei diesen Federkraftklemmen an die Anordnung eines Drückers innerhalb der Schlaufenform der Klemmfeder gedacht.Of the between the clamping leg and the plant leg lying back region the loop-shaped Clamping springs offers, based on the dimension of the respective clamping spring a longer one Way, over the bending area extends and the spring tension extends builds. this leads to at a cheaper Distribution of mechanical stresses, resulting in a correspondingly higher spring force results. However, equipped with the loop-shaped clamping springs spring terminals handle to cancel the clamping force not on, certainly not at these spring terminals to the arrangement of a pusher thought within the loop shape of the clamping spring.
Der Erfindung liegt die Aufgabe zugrunde; eine Federkraftklemme der eingangs genannten Art zu schaffen, mit der im Zuge der Miniaturisierung elektrischer oder elektronischer Bauteile sich eine sehr kleine Baugröße mit ausreichender Federkraft der Klemmfeder realisieren läßt.Of the Invention is based on the object; a spring terminal of the to create the aforementioned type, with the in the course of miniaturization electrical or electronic components are a very small size with sufficient Can realize spring force of the clamping spring.
Diese Aufgabe wird mit einer den Merkmalen des Patentanspruchs 1 entsprechenden Federkraftklemme gelöst.These Task is with a corresponding to the features of claim 1 Spring clamp released.
Für die Erfindung ist wesentlich, zum einen die günstigeren mechanischen Spannungsverhältnisse einer schlaufenförmig gebogenen Klemmfeder nutzen und zum zweiten einen Drücker vorsehen zu können, um den Klemmschenkel vom gegenüberliegenden Klemmwiderlager an der Innenseite des Anlageschenkels wegspreizen zu können. So können bei der miniaturisierten Ausbildung der erfindungsgemäßen Federkraftklemme auch dünne, empfindliche Litzen oder Drähte sicher und beschädigungsfrei geklemmt oder von der Federkraftklemme wieder gelöst werden.For the invention is essential, on the one hand, the cheaper mechanical tension conditions a looped shape use curved clamping spring and provide for the second a pusher to be able to around the clamping leg from the opposite Spread the clamping abutment on the inside of the abutment leg to be able to. So can at the miniaturized design of the spring clamp according to the invention also thin, delicate strands or wires safe and damage-free clamped or released from the spring-loaded terminal.
