Abstract

A contact region has a convex portion that extends from the contact region to a sprung region. A corresponding depression is formed in the side of a strip-shaped body opposite the convex portion. The sprung region of the strip-shaped body has a curved cross-section in the region of the convex/concave portions. An Independent claim is included for an electrical connector for audio applications.

Description

Die Erfindung bezieht sich auf ein Steckeraufnahmeteil einer elektrischen Steckverbindung, insbesondere für Audioanwendungen, mit einem zentralen Aufnahmeraum, welcher von einer Zwischenwand mit einer Innenseite und einer Außenseite begrenzt wird, und einem die Zwischenwand umgebenden kreisringförmigen Aufnahmeraum, wobei beide Aufnahmeräume Einstecköffnungen aufweisen und sowohl an der Innenseite als auch an der Außenseite der Zwischenwand Steckerkontakte angeordnet sind, welche einen metallischen streifenförmigen Körper besitzen, der einen Befestigungsbereich und einen vom Befestigungsbereich abstehenden freien Arm mit einem Kontaktbereich an seinem freien Ende und einem zwischen dem Kontaktbereich und dem Befestigungsbereich liegenden federnden Bereich aufweist.The invention relates to a plug receiving part of an electrical connector, in particular for audio applications, with a central receiving space, which is bounded by an intermediate wall with an inside and an outside, and an intermediate wall surrounding the annular receiving space, both receiving spaces have insertion and both at Inside as well as on the outside of the intermediate wall plug contacts are arranged, which have a metallic strip-shaped body having a mounting portion and a protruding from the mounting portion free arm with a contact portion at its free end and a lying between the contact region and the mounting portion resilient region.

Weiters bezieht sich die Erfindung auf eine elektrische Steckverbindung bestehend aus zwei Steckverbindern, von denen einer als Steckeraufnahmeteil und der andere als Steckteil ausgeführt ist, wobei in den Steckverbindern Kontakte angeordnet sind.Furthermore, the invention relates to an electrical connector consisting of two connectors, one of which is designed as a plug receiving part and the other as a plug-in part, wherein in the connectors contacts are arranged.

Steckeraufnahmeteile der eingangs genannten Art werden üblicherweise für Audioanwendungen, insbesondere als Lautsprecherstecker, teilweise auch als Stecker für die Stromversorgung von elektrischen Geräten eingesetzt. Bei diesen üblichen Anwendungsgebieten solcher Steckeraufnahmeteile von elektrischen Steckverbindungen müssen relativ hohe Ströme von mehr als 10 Ampere, meist bis 50 Ampere, übertragen werden können, wobei niedrige Übergangswiderstände wichtig sind. Es werden daher von den Steckerkontakten derartiger Steckeraufnahmeteile einerseits eine sehr gute Leitungsfähigkeit, andrerseits gute Federeigenschaften verlangt, damit der Steckerkontakt mit ausreichender Kraft an seinen Gegenkontakt gedrückt wird.Plug receiving parts of the type mentioned are usually used for audio applications, in particular as a speaker plug, sometimes as a plug for the power supply of electrical equipment. In these common applications of such connector receiving parts of electrical connectors relatively high currents of more than 10 amps, usually up to 50 amps, can be transmitted, with low contact resistance are important. Therefore, on the one hand, a very good conductivity and, on the other hand, good spring properties are required of the plug contacts of such plug-receiving parts, so that the plug contact is pressed with sufficient force against its mating contact.

Dokument D1:AT399427B beschreibt einen solchen Steckeraufnahmeteil nach der Präamble des Anspruchs 1.Document D1: AT399427B describes such a connector receiving part according to the preamble of claim 1.

Materialien mit guten Federeigenschaften, wie Bronze oder Federstahl, haben eine vergleichsweise weniger gute Leitungsfähigkeit. Andererseits haben gute Leiter, wie z.B. Kupfer, schlechtere Federeigenschaften. Aufgrund dieses Dilemmas wurden für Steckeraufnahmeteile der eingangs genannten Art bereits Steckerkontakte eingesetzt, bei denen ein Kupferteil auf einen Bronzeteil aufgenietet wurde, wodurch man die guten Leiteigenschaften des Kupfers mit den guten Federeigenschaften der Bronze kombinieren wollte. Eine derartige Ausführung eines Steckerkontaktes ist jedoch sehr teuer.Materials with good spring properties, such as bronze or spring steel, have a comparatively less good conductivity. On the other hand, good conductors, such as copper, have poorer spring properties. Because of this dilemma plug contacts were already used for plug-receiving parts of the type mentioned in which a copper part was riveted to a bronze part, whereby the good conductive properties of the copper with good spring properties wanted to combine the bronze. Such a design of a plug contact is very expensive.

Meist wird daher auf solche aufgenietete Kupferteile im Kontaktbereich des Steckerkontakts verzichtet und die Kontaktbereiche der aus Bronze bestehenden Steckerkontakte sind mit mehreren ausgestanzten Kontaktfahnen ausgebildet, welche die Gegenkontakte kontaktieren. Bei Steckeraufnahmeteilen der eingangs genannten Art mit solchen herkömmlichen Steckerkontakten ohne aufgenietete Kupferteile werden üblicherweise Übergangswiderstände von 5 bis 6 Milliohm erreicht.In most cases, therefore, such riveted copper parts are dispensed with in the contact region of the plug contact and the contact areas of the plug contacts made of bronze are formed with a plurality of punched-out contact lugs, which contact the mating contacts. In connector receiving parts of the type mentioned with such conventional plug contacts without riveted copper parts usually contact resistance of 5 to 6 milliohms are achieved.

Aufgabe der Erfindung ist es, ein Steckeraufnahmeteil der eingangs genannten Art bereitzustellen, bei dem eine elektrische Steckverbindung mit einem extrem niedrigen Übergangswiderstand ermöglicht wird. Als Ziel wurde ein Übergangswiderstand von 2 bis 3 Milliohm gesetzt. Dieses Ziel soll ohne ein auf den Steckerkontakt aufgenietetes Teil aus besonders gut leitendem Material erzielt werden.The object of the invention is to provide a plug receiving part of the type mentioned, in which an electrical connector is made possible with an extremely low contact resistance. The goal was a contact resistance of 2 to 3 milliohms. This goal should be achieved without a riveted on the plug contact part of particularly good conductive material.

Erfindungsgemäß gelingt dies durch ein Steckeraufnahmeteil einer elektrischen Steckverbindung mit den Merkmalen des Anspruchs 1.This is achieved by a plug receiving part of an electrical connector with the features of claim 1.

Dadurch, dass sich die Wölbung und die Mulde bzw. Wanne bis in den Federabschnitt des Steckerkontaktes hineinziehen, werden die Federeigenschaften des Steckerkontaktes positiv beeinflusst. Es kommt zu einer deutlichen Versteifung des vom Befestigungsbereich abstehenden freien Armes, wobei sich die Federeigenschaften über die Ausdehnung des Federabschnittes durch den Verlauf der Wölbung und der Mulde und die dabei sich ändernde Krümmung des Querschnitts des federnden Bereichs in vorgegebener Weise ändern können. Der erfindungsgemäße Steckerkontakt ist vorzugsweise aus Kupfer oder einer Kupferlegierung hergestellt, beispielsweise gestanzt.Due to the fact that the curvature and the depression or trough penetrate into the spring section of the plug contact, the spring properties of the plug contact are positively influenced. There is a significant stiffening of protruding from the attachment area free arm, with the spring properties on the extent of the spring portion by the course of the curvature and the trough and thereby changing the curvature of the cross section of the resilient portion can change in a predetermined manner. The plug contact according to the invention is preferably made of copper or a copper alloy, for example stamped.

Die Wölbung garantiert beim Kontaktieren eine gute Anlaufschräge in allen Richtungen.The curvature guarantees a good contact angle in all directions when contacting.

Durch die spezielle dreidimensionale Formgebung des Steckerkontaktes im Feder- und Kontaktbereich können die Federeigenschaften des Steckerkontaktes exakt gesteuert werden. Dadurch kann gut leitendes Material verwendet werden, wobei sich sowohl eine sehr gute Leitfähigkeit bzw. ein kleiner Bahnwiderstand des Steckerkontaktes als auch eine hohe Federkraft bzw. aufgrund des hohen Kontaktdruckes ein kleiner Kontaktübergangswiderstand der Steckverbindung ergeben.Due to the special three-dimensional shape of the plug contact in the spring and contact area, the spring characteristics of the plug contact can be precisely controlled. As a result, good conductive material can be used wherein both a very good conductivity or a small sheet resistance of the plug contact as well as a high spring force or due to the high contact pressure, a small contact resistance of the connector result.

Die Steckverbindung besteht in üblicher Art und Weise aus einem Steckeraufnahmeteil 1 und einem Steckteil 2. Das Steckteil 2 ist in das Steckeraufnahmeteil 1 einsteckbar und in diesem durch eine Schnellverschlusskupplung, beispielsweise in der Art eines Bajonettverschlusses verriegelbar.The plug-in connection consists in the usual way of a plug receiving part 1 and a male part 2. The male part 2 is inserted into the plug receiving part 1 and in this lockable by a quick release coupling, for example in the manner of a bayonet lock.

Das Steckeraufnahmeteil 1 besitzt einen zentralen Aufnahmeraum, welcher von einer Zwischenwand 13 mit einer Innenseite und einer Außenseite begrenzt wird, und einen die Zwischenwand 13 umgebenden kreisringförmigen Aufnahmeraum, wobei beide Aufnahmeräume Einstecköffnungen 15 aufweisen. Sowohl an der Innenseite als auch an der Außenseite der Zwischenwand 13 sind Steckerkontakte 3 angeordnet, welche zur Kontaktierung von Gegenkontakten 4 im Steckteil 2 dienen. Die Gegenkontakte 4 können in herkömmlicher Weise zylinderförmig ausgebildet sein, wie dies aus den Fig. 2, 4 und 5 ersichtlich ist. Die Gegenkontakte 4 sind an einem mittleren Zapfen 5 und an einer Wand 6 des Steckteiles 2 angeordnet. Der mittlere Zapfen 5 und die Wand 6 sind durch die Einstecköffnungen 15 in den zentralen Aufnahmeraum und den kreisringförmigen Aufnahmeraum des Steckeraufnahmeteils 1 einsteckbar.The plug receiving part 1 has a central receiving space which is delimited by an intermediate wall 13 with an inner side and an outer side, and an annular receiving space surrounding the intermediate wall 13, wherein both receiving spaces have insertion openings 15. Both on the inside and on the outside of the intermediate wall 13 plug contacts 3 are arranged, which serve for contacting mating contacts 4 in the male part 2. The mating contacts 4 may be cylindrical in a conventional manner, as is apparent from FIGS. 2, 4 and 5. The mating contacts 4 are arranged on a central pin 5 and on a wall 6 of the male part 2. The central pin 5 and the wall 6 can be inserted through the insertion openings 15 in the central receiving space and the annular receiving space of the connector receiving part 1.

Im gezeigten Ausführungsbeispiel sind im Steckeraufnahmeteil 1 vier elastische Steckerkontakte 3 angeordnet, die sich an der Zwischenwand 13 befinden und in Kreuzform angeordnet sind.In the illustrated embodiment, four elastic plug contacts 3 are arranged in the connector receiving part 1, which are located on the intermediate wall 13 and are arranged in a cross shape.

Die Steckkontakte 3 sind in der Nähe des Bodens 14 an der Zwischenwand 13 befestigt und ihre freien Enden mit den Kontaktbereichen 9 weisen zu den Einstecköffnungen 15 des Steckeraufnahmeteiles 1 hin.The plug contacts 3 are fastened in the vicinity of the bottom 14 on the intermediate wall 13 and their free ends with the contact areas 9 point towards the insertion openings 15 of the plug receiving part 1.

Die erfindungsgemäße Ausbildung der Steckerkontakte 3 ist insbesondere aus den Fig. 6 bis 17 ersichtlich.The inventive design of the plug contacts 3 can be seen in particular from FIGS. 6 to 17.

Die Steckerkontakte 3 weisen einen Befestigungsbereich 7 auf, von dem ein freier Arm absteht, der einen federnden Bereich 8 bildet (der etwa an der Stelle des in Fig. 10 eingezeichneten Schnittes DD beginnt) und im Bereich von dessen Spitze der Kontaktbereich 9 ausgebildet ist. Der freie Arm des Steckerkontaktes 3 ist löffelartig ausgeführt, wobei die löffelartige Mulde sich über den Kontaktbereich 9 und über zumindest einen Teil, vorzugsweise einen Großteil, des federnden Bereichs 8 erstreckt. Er weist dabei an einer Seite eine vom Kontaktbereich 9 ausgehende Wölbung 10 auf und an der gegenüberliegenden Seite eine korrespondierende Mulde 11, die von einem Rand 12 des Steckerkontaktes 3 abgegrenzt wird, der im Befestigungsbereich 7 seitlich am Steckerkontakt angeordnet ist und im Bereich der Wölbung 10 bzw. Mulde 11 gegenüber der Hauptebene des Steckerkontaktes im Befestigungsbereiche 7 geneigt ist und auf die Seite des Steckerkontaktes 3 weist, auf der die Mulde 11 angeordnet ist. Die Wölbung 10 und die Mulde 11 erstrecken sich weit in den federnden Bereich 8 des Steckerkontaktes 3 hinein, wobei sie in der Höhe bzw. Tiefe von einem Maximalwert im bzw. in der Nähe des Kontaktbereiches 9 zum Befestigungsbereich 7 hin und über bzw. in demselben stetig auslaufen (siehe insbesondere Fig. 11 und 12). Im Querschnitt gesehen (Fig. 13 und 14) ist der federnde Bereich 8 über die Ausdehnung der Mulde bzw. Wölbung gekrümmt ausgebildet.The plug contacts 3 have a fastening region 7, from which a free arm protrudes, which forms a resilient region 8 (which begins approximately at the location of the section DD drawn in FIG. 10) and in the region of the tip of which the contact region 9 is formed. The free arm of the male contact 3 is spoon-shaped, wherein the spoon-like trough extends over the contact region 9 and over at least a part, preferably a major part, of the resilient region 8. He has in this case on one side of the contact area 9 outgoing buckle 10 and on the opposite side a corresponding recess 11, which is delimited by an edge 12 of the plug contact 3, which is arranged laterally on the plug contact in the attachment area 7 and in the region of the curvature 10th or trough 11 is inclined relative to the main plane of the plug contact in the attachment areas 7 and points to the side of the plug contact 3, on which the trough 11 is arranged. The buckle 10 and the trough 11 extend far into the resilient region 8 of the plug contact 3, wherein they in the height or depth of a maximum value in or in the vicinity of the contact region 9 towards the attachment region 7 and over or in the same steadily leak (see in particular Figs. 11 and 12). Seen in cross-section (FIGS. 13 and 14), the resilient region 8 is curved over the extent of the trough or curvature.

Durch diese Ausführung des freien Armes werden die Federeigenschaften des Steckerkontaktes 3 im federnden Bereich 8 wesentlich verbessert (unter Erhöhung der Federkonstanten bzw. Versteifung des vom Befestigungsbereich abstehenden freien Armes), wobei aber die Leitfähigkeit unbeeinflusst bleibt. Durch die Änderung der Tiefe der Mulde 11 bzw. der Höhe der Wölbung 10 ändern sich die Federeigenschaften über den federnden Bereich 8, wobei die Federkonstante in Richtung zum Kontaktbereich 9 zunimmt. Ein erfindungsgemäßer Steckerkontakt 3 kann aus Kupfer oder einer Kupferlegierung hergestellt werden, wodurch die guten Leiteigenschaften des Materials genützt werden und dennoch wird eine ausreichende Federkraft erzielt, die den Kontaktbereich 9 an die Gegenkontakte 4 im Steckteil 2 drückt.By this embodiment of the free arm, the spring properties of the plug contact 3 in the resilient region 8 are substantially improved (by increasing the spring constants or stiffening of protruding from the mounting area free arm), but the conductivity remains unaffected. By changing the depth of the trough 11 or the height of the curvature 10, the spring properties change over the resilient region 8, wherein the spring constant increases in the direction of the contact region 9. An inventive plug contact 3 can be made of copper or a copper alloy, whereby the good conductive properties of the material are used and yet a sufficient spring force is achieved, which presses the contact portion 9 to the mating contacts 4 in the male part 2.

Erfindungsgemäße Steckeraufnahmeteile eignen sich besonders für Hochstromanwendungen, bei denen beispielsweise Stromstärken von bis zu 50 Ampere geleitet werden müssen. Insbesondere können erfindungsgemäße Steckerkontakte in elektrischen Steckverbindungen für Audioanwendungen vorteilhaft eingesetzt werden. Ein Beispiel hierfür sind sogenannte Lautsprecherstecker zur Verbindung von Lautsprechern mit Lautersprecherkabeln bzw. von Lautersprecherkabeln mit Verstärkerausgängen.Plug receptacles according to the invention are particularly suitable for high-current applications in which, for example, currents of up to 50 amperes have to be conducted. In particular, plug contacts according to the invention can be advantageously used in electrical plug connections for audio applications. An example of this are so-called loudspeaker plugs for connecting loudspeakers with loudspeaker cables or loudspeaker cables with amplifier outputs.
