The fixing section has two flexible shanks (5, 6) of different lengths, which extend parallel to each other in a direction away from the contacting section. The longer shank (5) is formed such that, under compressive load. The shorter shank (6) of the overlapping end section (10) bends in the direction of the contacting section. The longer shank bends away from the shorter shank and the shorter shank with its end section bends away from the longer shank. An independent claim is also included for an electrical contact arrangement with a printed circuit board and a metallic contact element, which has two shanks.

Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem metallischen Kontaktelement nach der Gattung des Patentanspruchs 1.The invention relates to a metallic contact element according to the preamble of patent claim 1.

Um Steckkontakte, z.B. Kontaktstifte, mit einer aus elektrisch isolierendem Material hergestellten Platine (auch Leiterplatte genannt) dauerhaft zu kontaktieren, wird Einpresstechnik eingesetzt. Ein runder, bolzenförmiger Befestigungsabschnitt des Kontaktelements wird in ein Leiterplattenloch gepresst, das durch eine in die Leiterplatte eingebrachte verzinnte Hülse gebildet ist. Die Einpresszone wird dabei plastisch und elastisch verformt, wodurch es an den Berührungsstellen zu einer dauerhaft festen Kaltverschweißung zwischen Metallteilen kommt. Beim Einpressen entstehen durch Abschälen Metallspäne, die Kurzschlüsse oder Nebenschlüsse (= hochohmige Kurzschlüsse) verursachen können. Außerdem kann durch die axiale Kraftbeaufschlagung während des Einpressprozesses die in die Leiterplatte eingebrachte verzinnte Hülse beschädigt werden, wodurch die Qualität der elektrischen Verbindung sofort oder erst nach langer Betriebszeit beeinträchtigt werden kann.In order to permanently contact plug-in contacts, eg contact pins, with a printed circuit board made of electrically insulating material (also called printed circuit board), press-fit technology is used. A round, bolt-shaped attachment portion of the contact element is pressed into a printed circuit board hole, which is formed by a tinned sleeve introduced into the circuit board. The press-in zone is plastically and elastically deformed, resulting in a permanently strong cold welding between metal parts at the points of contact. When pressed in, metal chips form due to peeling, which can cause short circuits or shunts (= high-resistance short circuits). In addition, by the axial application of force during the Einpressprozesses in the circuit board introduced tinned sleeve can be damaged, whereby the quality of the electrical connection can be affected immediately or only after a long period of operation.

Kaltverschweißung kann auch zwischen anderen Metallen auftreten, z. B. zwischen Gold-Gold und Kupfer-Kupfer. Wie auch Zinn, sind die zuletzt genannten Metalle im Zusammenhang mit der Herstellung von Leiterplatten bekannt. Der Ausdruck Zinn bedeutet in dieser Beschreibung eine Zinn enthaltende Legierung, die für elektrische Kontaktzwecke geeignet ist. Der Fachmann wählt eine für den gewünschten Anwendungsfall geeignete Zinnlegierung aus bekannten Legierungen aus.Cold welding can also occur between other metals, eg. B. between gold-gold and copper-copper. Like tin, the latter metals are known in connection with the production of printed circuit boards. The term tin in this specification means a tin-containing alloy suitable for electrical contact purposes. The person skilled in the art selects a tin alloy suitable for the desired application from known alloys.

Offenbarung der ErfindungDisclosure of the invention

Bei dem erfindungsgemäßen Kontaktelement wird Spanbildung sicher vermieden, da das Kontaktelement mit seiner Vorderseite beim Einführen in das Loch nicht an der Lochwand schabt. Das Einführen des Kontaktelements ist mit keiner bzw. geringerer Kraftbeaufschlagung verbunden als bei bekannten Einpresstechniken. Eine Beschädigung der verzinnten Hülse durch das Einpressen wird daher vermieden. Die zum Erzeugen der für das Kaltverschweißen erforderliche Kraft erfolgt mithilfe umgebogener Schenkel und gegebenenfalls zusätzlich mithilfe einer Keilwirkung. Da keine Späne auftreten, ist die Gefahr von Kurz- oder Nebenschlüssen praktisch beseitigt. Es wird auch der Kontaktierprozess vereinfacht, da eine Schädigung der verzinnten Hülse in der Leiterplatte durch das Einpressen einer Einpressgeometrie konzeptionell entfällt. Auch wird die Leiterplatte im Bereich der Kontaktierung deutlich weniger gestresst. Es ist eine hohe Kontaktsicherheit mit gutem Langzeitverhalten zu erwarten. Weiterhin sind prinzipiell große Haltekräfte möglich, da die Kontaktierzone des Befestigungsabschnitts nach der plastischen Umformung einen Hinterschnitt bildet. Wenn auch mehrere Metalle sich für Kaltverschweißungen eignen, wird Zinn bevorzugt.In the contact element according to the invention chip formation is reliably avoided because the contact element with its front when scraping into the hole does not scrap on the hole wall. The insertion of the contact element is associated with no or less force than in known Einpresstechniken. Damage to the tinned sleeve by the pressing is therefore avoided. The force required to produce the cold-welding takes place by means of a bent leg and if necessary additionally by means of a wedging action. Since no chips occur, the risk of short circuits or shunts is virtually eliminated. The contacting process is also simplified since damage to the tinned sleeve in the printed circuit board by means of the press-fitting of a press-fit geometry is conceptually eliminated. Also, the printed circuit board is significantly less stressed in the contact area. It is to be expected a high contact security with good long-term behavior. Furthermore, in principle, large holding forces are possible because the contacting of the mounting portion forms an undercut after the plastic deformation. Although several metals are suitable for cold welding, tin is preferred.

Ausführungsform der ErfindungEmbodiment of the invention

Das in Fig. 1 gezeigte Kontaktelement 1 ist aus verzinntem Blech (im Beispiel Messingblech) gestanzt und weist einen oberen Kontaktierabschnitt 2, einen unteren Befestigungsabschnitt 3 und dazwischen zwei seitliche Vorsprünge 4 auf. Der Kontaktierabschnitt 2 ist zum Beispiel ein im Querschnitt etwa rechteckiger Kontaktstift oder ein Messerkontakt in Form eines Flachsteckers. Der Befestigungsabschnitt 3 weist zwei nach unten ragende Schenkel 5, 6 mit unterschiedlicher Länge auf. Ausgehend von den Vorsprüngen 4 weisen die beiden Schenkel 5, 6 auf ihren einander abgewandten Seiten jeweils nach unten aufeinander zulaufende Keilflächen 7 und daran anschließend zueinander parallele Außenflächen 8, 9 auf. Der längere Schenkel 5 steht mit einem Endabschnitt 10 über den kürzeren Schenkel 6 vor, wobei der Endabschnitt 10 hakenförmig zum kürzeren Schenkel 6 umgebogen ist und eine nach unten gerichtete Spitze 11 aufweist. Diese Spitze 11 ist um den Betrag a außermittig zur Mittelebene 12 des längeren Schenkels 5 angeordnet. Der kürzere Schenkel 6 weist eine zum längeren Schenkel 5 weisende schräge Endfläche 13 auf.The contact element 1 shown in FIG. 1 is stamped from tinned sheet metal (in the example brass sheet metal) and has an upper contacting section 2, a lower fastening section 3 and two lateral projections 4 therebetween. The Kontaktierabschnitt 2 is for example a cross-sectionally approximately rectangular contact pin or a blade contact in the form of a tab. The attachment portion 3 has two downwardly projecting legs 5, 6 with different lengths. Starting from the projections 4, the two legs 5, 6 on their sides facing away from each other down to each other tapered wedge surfaces 7 and then parallel to each other outer surfaces 8, 9. The longer leg 5 protrudes with an end portion 10 on the shorter leg 6, wherein the end portion 10 is hook-shaped bent to the shorter leg 6 and has a downwardly directed tip 11. This tip 11 is arranged eccentrically to the median plane 12 of the longer leg 5 by the amount a. The shorter leg 6 has an oblique end face 13 facing the longer leg 5.

In Fig. 2a ist das Kontaktelement 1 mithilfe eines Stempels 14, der von oben auf die Vorsprünge 4 wirkt, in ein rundes Loch 15 einer Leiterplatte 16 eingeschoben worden, wobei der zugespitzte Endabschnitt 10 des längeren Schenkels 5 eine Einführhilfe darstellt. Mit Ausnahme ihrer Keilflächen 7 hat der Befestigungsabschnitt 3 einen Querschnitt hat, der allseits kleiner ist als der Durchmesser des Loches 15. Das Loch 15 ist durch eine verzinnte Hülse 17 gebildet, die in die Leiterplatte 16 eingebracht ist. Der Einschiebevorgang verläuft nahezu kraftlos, weil die Schenkel 5, 6 mit Ausnahme ihrer Keilflächen 7 ohne Widerstand in das Loch 15 eingeschoben werden können. Erst wenn die Keilflächen 7 mit der Wand 18 des Lochs 15 in Berührung kommen, ist eine merkliche Kraft (Fügekraft) durch den Stempel 15 aufzubringen, damit die Keilflächen 7 sich in die Lochwand 18 eindrücken können, wodurch an der Leiterplattenoberseite im Bereich 19 eine Kaltverschweißung, d.h. ein oberer Kontaktbereich, erzeugt wird.In Fig. 2a, the contact element 1 by means of a punch 14, which acts from above on the projections 4, has been inserted into a round hole 15 of a printed circuit board 16, wherein the pointed end portion 10 of the longer leg 5 a Introducer. With the exception of its wedge surfaces 7, the attachment portion 3 has a cross section which is smaller than the diameter of the hole 15 on all sides. The hole 15 is formed by a tinned sleeve 17 which is inserted in the printed circuit board 16. The insertion process is almost powerless, because the legs 5, 6 with the exception of their wedge surfaces 7 without resistance can be inserted into the hole 15. Only when the wedge surfaces 7 come into contact with the wall 18 of the hole 15, a significant force (joining force) by the punch 15 is applied so that the wedge surfaces 7 can press into the hole wall 18, whereby on the circuit board top in the region 19, a cold welding ie an upper contact area is generated.

Nun wird von unten her ein Gesenk 20 (Umformwerkzeug) gegen den Endabschnitt 10 durch eine Antriebskraft gedrückt, wie durch den Pfeil 21 angedeutet ist. Dadurch wird der längere Schenkel 5 nach links gebogen und teilweise umgebogen, bis er schließlich mit seiner Endfläche (Hakenfläche) 22 gegen die Endfläche 13 des kürzeren Schenkels 6 stößt und diesen nach rechts umbiegt und abstützt. Das speziell geformte Gesenk 20 unterstützt diesen Prägevorgang oder Umformvorgang. Die Verprägung der Schenkel 5, 6 verursacht zum einen, bedingt durch die außermittige Belastung des längeren Schenkels 5 und die speziell geformte Gesenkgeometrie, ein Einrollen des längeren Schenkels 5, zum anderen wird hierdurch der kürzere Schenkel 6 nach außen verdrängt. Wesentlich für die Verprägung ist das Aufweiten der beiden Schenkel 5, 6 in Relation zum Loch 15. Hierdurch entsteht im Bereich des Loches 15 an der Leiterplattenunterseite ein Formschluss, der jede Relativbewegung zwischen dem Kontaktelement 1 und der Lochwand 18 verhindert. Dadurch wird, wie in Fig. 2b gezeigt, an der Leiterplattenunterseite im Bereich 23 eine Kaltverschweißung, d.h. ein unterer Kontaktbereich, erzeugt. Eine axiale Belastung der verzinnten Hülse 17 oder ihrer metallischen Hülseninnenwand 18 wie bei der bekannten Einpresstechnik entfällt. Eine Spanbildung tritt entweder nicht auf, oder, sofern durch die Keilflächen 7 doch Späne abgespant werden, sind diese unverlierbar zwischen den Vorsprüngen 4 und den verprägten Schenkeln 5, 6 gehalten. In Fig. 2b ist die Kontaktanordnung aus Leiterplatte 16, Hülse 17 und verprägtem Kontaktelement 1 insgesamt mit 24 bezeichnet.Now, from below a die 20 (forming tool) is pressed against the end portion 10 by a driving force, as indicated by the arrow 21. Thus, the longer leg 5 is bent to the left and partially bent until it finally abuts with its end face (hook surface) 22 against the end face 13 of the shorter leg 6 and this bends to the right and supported. The specially shaped die 20 supports this embossing or forming process. The embossment of the legs 5, 6 caused on the one hand, due to the eccentric load of the longer leg 5 and the specially shaped Gesenkgeometrie, a curling of the longer leg 5, on the other hand thereby the shorter leg 6 is displaced to the outside. Essential for the embossment is the expansion of the two legs 5, 6 in relation to the hole 15. This creates in the region of the hole 15 on the circuit board underside a form fit, which prevents any relative movement between the contact element 1 and the hole wall 18. As a result, as shown in FIG. 2b, a cold welding, ie a lower contact region, is produced on the underside of the printed circuit board in region 23. An axial load of the tinned sleeve 17 or its metallic sleeve inner wall 18 as in the known press-in technology is eliminated. Chip formation either does not occur or, if shavings are shaved off by the wedge surfaces 7, they are held captive between the projections 4 and the embossed legs 5, 6. In Fig. 2b, the contact arrangement of printed circuit board 16, sleeve 17 and embossed contact element 1 is generally designated 24.

Alternativ oder zusätzlich zur außermittigen Anordnung der Spitze 11 bzw. des Endabschnitts 10 des längeren Schenkels 5 kann dieser auch auf seiner dem kürzeren Schenkel 6 zugewandten Seite eine in Fig. 1 gestrichelt dargestellte Kerbe 25 aufweisen. Diese Kerbe 25 bewirkt, dass der längere Schenkels 5 sich unter Druckbelastung nach links biegt und mit seinem Endabschnitt 10 den kürzeren Schenkel 6 nach links umbiegt.Alternatively or in addition to the eccentric arrangement of the tip 11 and the end portion 10 of the longer leg 5, this may also have on its shorter leg 6 side facing a dashed line notch 25 shown in FIG. This notch 25 causes the longer leg 5 bends to the left under pressure load and with its end portion 10, the shorter leg 6 bends to the left.
