Abstract
Description
Die Erfindung betrifft eine Steckverbindung auf einem Stanzgitter für eine Platine oder Leiterplatte, wobei ein Anschlusskontakt eines Schalters, oder eines anderen elektrischen Bauteils, ein Loch oder eine Aufnahme oder eine Ausnehmung aufweist und wobei ein korrespondierendes Steckelement aus dem Stanzgitter gebogen ist.The The invention relates to a connector on a stamped grid for a Board or circuit board, wherein a terminal contact of a switch, or another electrical component, a hole or a receptacle or has a recess and wherein a corresponding plug-in element bent out of the stamped grid.
Derartige
Steckverbindungen sind im Stand der Technik bekannt, vgl. beispielsweise
die Druckschriften
Auch im Verlauf der Entwicklungsarbeiten, die der vorliegenden Erfindung zugrunde liegen, wurde immer wieder festgestellt, dass bei den „elastischen Lösungen" nach dem Stand der Technik ein zu hoher Übergangswiderstand auftreten kann. Die elastische Kraft kann durch Materialänderungen mit der Zeit erlahmen. Auch durch eine schockartige thermische Belastung kann der Übergangswiderstand steigen. Die Aufgabe der Erfindung besteht deshalb darin, eine dauerhafte Kontaktierung der elektrischen Anschlüsse zwischen dem Schalter (oder einem vergleichbaren elektrischen Bauteil) einerseits und dem Stanzgitter andererseits zu erreichen, und zwar ohne die Gefahr einer Erhöhung des Übergangswiderstandes.Also in the course of development work, that of the present invention underlying, was repeatedly found that in the "elastic Solutions "according to the prior art too high contact resistance can occur. The elastic force can be due to material changes decayed over time. Also by a shock-like thermal load the contact resistance can rise. The object of the invention is therefore a permanent contact of the electrical Connections between the switch (or a comparable electrical component) on the one hand and the lead frame on the other without the risk of an increase in contact resistance.
Die Lösung dieser Aufgabe besteht nach dem Patentanspruch 1 darin, ein rundliches oder ovales Loch mit einem vieleckigen Steckelement zu fügen, wobei ein diagonales Maß des Steckelements größer ist als der Lochdurchmesser. Durch die entstehende Presspassung wird eine plastische Materialverformung der korrespondierenden Kontaktelemente und damit eine dauerhafte Kontaktkraft nach Art einer Schweißverbindung erzielt. Der Fachmann spricht von Kalt schweißverbindung oder Mikroschweißverbindung. Sie ist erfindungsgemäß dafür verantwortlich, dass eine dauerhafte und feste Kontaktierung entsteht. Durch den Druck beim Einpressen des Steckelements in das Kontaktloch herrscht eine ausreichend hohe Presskraft, um die Kontaktflächen kalt miteinander zu verschweißen. Mit einem federnden Steckelement und einem federnden Anschlusskontakt wäre eine solche Verbindung nicht möglich.The Solution to this problem consists of the patent claim 1 in it, a roundish or oval hole with a polygonal plug element to add, with a diagonal dimension of the plug element larger is the hole diameter. Due to the resulting interference fit becomes a plastic material deformation of the corresponding contact elements and thus a permanent contact force in the manner of a welded joint achieved. The expert speaks of cold welding connection or microwelding connection. It is according to the invention for it responsible, that a permanent and firm contact arises. By the pressure during the pressing of the plug element in the contact hole prevails a sufficiently high pressing force around the contact surfaces cold to weld together. With a springy plug element and a resilient terminal contact would be such a connection not possible.
Als Material, um die plastische Verformung zu erreichen, werden Kupferlegierungen wie z. B. Bronze oder Messing bevorzugt. Auch Stähle können verwendet werden; generell spricht der Fachmann von kontaktfähigen Metallen und Metall-Legierungen. Es ist auch denkbar, metallisierte Kunststoffe zu verwenden, sofern sie ein ausreichendes Kriechverhalten aufweisen.When Material to achieve plastic deformation become copper alloys such as As bronze or brass preferred. Steels can also be used become; In general, the expert speaks of contactable Metals and metal alloys. It is also possible to metallized To use plastics, provided they have sufficient creep behavior exhibit.
Zur Montage wird zunächst das Steckelement aus dem Stanzgitter gebogen, mit Einführschrägen versehen und dann durch das Loch gepresst. Typischerweise sind zwei der Einführschrägen durch Stanzen hergestellt und die beiden anderen Seiten des Steckelements durch Prägen vorbereitet. Vorteilhafterweise wird so eine Stromübertragung durch die Kontaktstelle, die sich auch über die Nutzungszeit oder durch Thermoschock nicht verändert, ohne großen Übergangswiderstand erreicht. Die erfindungsgemäß vorgesehene plastische Verformung führt also zu besseren technischen Eigenschaften als die im Stand der Technik übliche elastische Kontaktgabe mit der Gefahr einer plastischen Nachverformung.to Assembly is first the plug element from the stamped grid bent, provided with chamfers and then pressed through the hole. Typically, two of the insertion bevels made by punching and the other two sides of the plug element prepared by embossing. Advantageously, such a Power transmission through the contact point, which is also over the period of use or not changed by thermal shock, achieved without great contact resistance. The According to the invention provided plastic deformation leads to better technical properties than the in the prior art customary elastic contact with the risk of plastic deformation.
In Weiterbildung der Erfindung ist vorgesehen, Maßänderungen der Kontaktpartner Rechnung zu tragen, die durch Montage-Ungenauigkeiten oder durch Temperatureinflüsse entstehen können. Hierzu ist ein Längenausgleich in der Ebene des Stanzgitters während des Einpressvorgangs als Möglichkeit vorgesehen. Der Längenausgleich wird insbesondere vermittelt durch eine mäanderförmige Anbindung des Anschlusskontakts mit seiner Lochgeometrie an den elektrischen Schalter (oder allgemein an das elektrische Bauelement). An dieser Stelle und in dieser Ebene ist also eine kleine elastische Bewegung möglich, so dass die letztendliche Entfernung des Anschlusskontaktlochs von dem elektrischen Schalter verschieden lang sein kann. Bei den kleinen Kräften, die zwecks Längenausgleich horizontal auf die mäanderförmige Anbindung wirken, ist auch bei dem erfindungsgemäßen Material eine elastische Auslenkung oder Rückstellung möglich. Die großen Presskräfte in vertikaler Richtung bewirken jedoch die plastischen Veränderungen direkt an den Kontaktstellen.In Further development of the invention is provided, dimensional changes the contact partners due to assembly inaccuracies or caused by temperature influences. For this purpose, a length compensation in the plane of the stamped grid provided during the Einpressvorgangs as a possibility. The length compensation is in particular mediated by a meandering connection of the terminal with its hole geometry to the electrical switch (or in general to the electrical component). At this point and in this level So a small elastic movement is possible, so that the eventual removal of the terminal via from the electrical Switch can be different lengths. At the small forces, for the purpose of length compensation horizontally on the meandering Connectivity act, is also in the inventive Material an elastic deflection or provision possible. The large pressing forces in the vertical direction however, cause the plastic changes directly the contact points.
