Description
KlemmvorrichtungClamping device
Durch die ÜS-Patentschrift 3 112 147 ist eine Klemmvorrichtung für den Anschluß elektrischer Leitungen "bekannt, "bei welcher die beiden Backen einer Klemme zunächst'als einheitlicher Stanzteil mit einer schlitzartigen Durchbrechung.hergestellt und sodann durch Scheren senkrecht zur Materialebene an ihrem äußeren Ende voneinander getrennt werden«. Die dadurch gewonnene Klemme gestattet die Herstellung einer elektrischen Verbindung zu einem isolierten Leiter, da die Backen beim Einschieben des Leiters die Isolation durchschneiden. Jedoch ist bei dem Herstellungsverfahren durch Stanzen oder Scheren eine Oberflächenbehandlung der kontaktgebenden Flächen der Klemme nicht möglich, da diese Flächen im Ruhezustand gegeneinander liegen.The ÜS patent specification 3 112 147 is a Clamping device for the connection of electrical lines "known" in which the two jaws a clamp initially as a uniform stamped part with a slot-like opening and then separated from one another by shears perpendicular to the plane of the material at their outer end ". The terminal obtained in this way allows an electrical connection to be made to an insulated one Conductor, as the jaws cut through the insulation when the conductor is pushed in. However, with that Manufacturing process by punching or shearing a surface treatment of the contacting surfaces of the Clamping is not possible because these surfaces lie against one another when at rest.
Die Hieüermig bezweckt, die Nachteile der bekannten Klemmvorrichtung zu vermeiden. Dies wird dadurch ermöglicht, daß beide Backen einer Klemme zunächst als gesonderte Ansätze eines gemeinsamen Stanzteiles ausgeformt und sodann durch Verbiegen in der Ebene des Stanzteiles auf die gewünschte Entfernung voneinander eingestellt sind. Die Heuerung ermöglicht es, die Entfernung der Backen voneinander dem Durchmesser des verwendeten Leiters anzupassen, so daß beim Einschieben eines isolierten Leiters zwischen die Backen der.Klemme mit Sicherheit zwar die Isolation durchtrennt wird, die Backen der Klemme sodann jedoch nur mit dem gewünschtenThe Hieüermig aims to address the disadvantages of the known Avoid clamping device. This is made possible by that both jaws of a clamp are initially formed as separate approaches of a common stamped part and then by bending in the plane of the stamping the desired distance from one another are set. The hiring allows the distance between the jaws to be the diameter of the used conductor to adapt, so that when inserting an insulated conductor between the jaws of the.Klemme certainly the insulation is cut, the Bake the clamp then only with the desired

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Es zeigen :An embodiment of the invention is shown in the drawing. Show it :
Fig. 1 eine Ansicht des Werkstückes nachFig. 1 is a view of the workpiece according to
dem ersten Verfahrensschritt nach der Formgebung durch Stanzen ;the first process step after shaping by punching;
Fig. 2 eine Ansicht der fertigen KlemmeFigure 2 is a view of the finished clamp
Fig. 3 einen Schnitt durch die fertige Klemme längs der Linie 3 3 in Fig. 2.FIG. 3 shows a section through the finished clamp along the line 33 in FIG. 2.
Durch Stanzen werden an der einen Kante eines Blechstreifens 10 fingerförmige Ansätze 11 und 12 ausgeformt, zwischen denen Schlitze 13 und 14 liegen. Zwei benach-. barte Finger 11 und 12 gehören zu einer Klemme; der zwischen ihnen liegende Schlitz 13 ist etwas tiefer als der Schlitz 14 zwischen den Fingern 11 und 12 zweier verschiedener Klemmen.By punching 10 finger-shaped attachments 11 and 12 are formed on one edge of a sheet metal strip, between which slots 13 and 14 are located. Two adjacent. bearded fingers 11 and 12 belong to a clamp; the The slot 13 lying between them is somewhat deeper than the slot 14 between the fingers 11 and 12 two different clamps.
Fach dem Ausstanzen gemäß Fig. 1 ist eine Bearbeitung der Oberfläche der Finger 11 und 12 insbesondere der einander zugewandten Flächen der Finger 11 und einer Klemme möglich.Subject the punching according to FIG. 1 is a processing the surface of the fingers 11 and 12, in particular the mutually facing surfaces of the fingers 11 and a clamp possible.
Der Fußpunkt der Klemmfinger 11 und 12.. an den Schlitzen 14 zwischen den Klemmfingern benachbarter Klemmen wird sodann durch Prägen verformt. An den Prägestellen ist die Dicke des Materials vermindert. Durch die Prägung werden die Finger 11 und 12 verschiedener Klemmen in der Ebene des Materiales voneinander weggebogen, und zwar unter Überwindung der Streckgrenze desThe base of the clamping fingers 11 and 12 .. at the slots 14 between the clamping fingers of adjacent clamps is then deformed by embossing. At the embossing points the thickness of the material is reduced. The embossing makes the fingers 11 and 12 more different Clamps bent away from each other in the plane of the material, overcoming the yield point of the
Materials, so daß die Pinger 11 und 12 die durch. Beistellung mittels Prägung eingenommene Lage beibehalten.Materials so that the pingers 11 and 12 through. Maintain position assumed by means of embossing.
Die Beistellung wird nur in solchem Ausmaße vorgenommen, daß die fingerförmigen Kontaktmesser 11 und 12 einer Klemme zwar die Isolation 16 einer zwischen die Y-fb'rmig gegabelten Enden der Pinger 11 und 12 eingeführten Leitung glatt durchschneiden, jedoch nur um ein geringes Maß in die Kupferseele 15 der Leitung eindringen» Je nach den verwendeten Drahtstärken kann der Grad der Beistellung abgestimmt werden.The provision is only made to such an extent that the finger-shaped contact blades 11 and 12 one It is true that the insulation 16 of one of the Y-shaped forked ends of the pingers 11 and 12 is clamped Cut straight through the line, but only penetrate a small amount into the copper core 15 of the line The degree of provision can be coordinated with the wire sizes used.
