Eine Steckverbindereinheit mit einem Buchsenteil, das eine Schaltfunktion aufweist, ist z. B. in WO 98/31078 beschrieben. Das dortige Buchsenteil weist einen zentrisch im Buchsenteil sitzenden Kontaktstift auf, der beim Aufstecken eines Steckerteils axial von der Stecköffnung weggedrückt wird. Der Kontaktstift ist auf seinem der Steckseite abgewandten Ende mit einem Federschenkel einer Kontaktfeder in Berührung. Diese Kontaktfeder berührt mit ihrem Kontaktschenkel im Ruhezustand, d. h. wenn kein Steckerteil auf das Buchsenteil aufgesteckt ist, einen Gegenkontakt. Wird ein Steckerteil auf das Buchsenteil gesteckt, drückt der Kontaktstift des Buchsenteils den Federschenkel der Kontaktfeder vom Gegenkontakt weg, so dass sich die elektrische Verbindung zwischen Kontaktfeder und Gegenkontakt löst. Die virtuelle Biegeachse der Kontaktfeder steht senkrecht zur Steckrichtung.A connector unit with a female part, the one Has switching function, z. As described in WO 98/31078.

Of the Contact pin is on its end facing away from the plug side with a spring leg of a contact spring in contact. These Contact spring touches with its contact leg at rest, d. H. if no plug part is attached to the socket is, a mating contact. Is a plug part on the socket part inserted, pushes the contact pin of the socket part the spring leg of the contact spring from the mating contact away, so that the electrical connection between contact spring and counter contact triggers. The virtual bending axis of the Contact spring is perpendicular to the plug-in direction.

Eine solche Anordnung zeichnet sich durch einen verhältnismäßig komplizierten Aufbau aus. Darüber hinaus benötigt das Buchsenteil zwingend einen mittigen Kontaktstift, über den die Kontaktfeder bewegt wird. Insgesamt weist das Buchsenteil einen verhältnismäßig hohen axialen Bauraum auf.Such an arrangement is characterized by a relative complicated construction. In addition, that requires Socket compelling a central contact pin, over the the contact spring is moved. Overall, the socket part a relatively high axial space.

In den nachfolgenden Figuren bezeichnen, sofern nicht anders angegeben, gleiche Bezugszeichen gleiche Teile mit gleicher Bedeutung.In the following figures, unless otherwise stated indicated, like reference numerals like parts with the same Importance.

Das in den Figuren 1 bis 3 in unterschiedlichen Ansichten dargestellte Buchsenteil 10 ist um eine Mittenachse X aufgebaut und weist ein topfförmiges Gehäuse 12 auf, welches am Gehäuseboden über vier im rechten Winkel nach außen abgewinkelte Gehäusefüße 12b verfügt. Auf der dem Gehäuseboden abgewandten Seite, d. h. der Steckseite, weist das Gehäuse 12 eine nach innen schräg abgewinkelte Gehäusewandung 12a auf. Diese Gehäusewandung 12a des Gehäuses 12 verläuft trichterförmig nach innen und dient als Einführhilfe für das in Zusammenhang mit den Figuren 6 bis 8 noch zu erläuternde Steckerteil. Das Gehäuse 12 besteht aus Metall und ist vorzugsweise als Tiefziehteil hergestellt.That in Figures 1 to 3 in different views illustrated female part 10 is constructed around a center axis X. and has a cup-shaped housing 12, which on Caseback bent over four at right angles to the outside Housing feet 12b features. On the side facing away from the case back Page, d. H. the plug side, the housing 12 an inwardly angled obliquely housing wall 12a. This housing wall 12a of the housing 12 is funnel-shaped inside and serves as an introduction aid for the related with the figures 6 to 8 yet to be explained plug part. The housing 12 is made of metal and is preferably manufactured as a deep-drawn part.

In dem Gehäuse 12 sitzt ein Isolierteil 14. Dieses Isolierteil 14 ist vorzugsweise klemmend in dem Gehäuse 12 gehalten. Diese klemmende Halterung wird beispielsweise dadurch erreicht, dass der untere Gehäuserand etwas verstemmt wird, nachdem das Isolierteil 14 in das Gehäuse 12 eingeschoben ist. Zusätzlich weist das Isolierteil 14 eine oder mehrere Identifikationsnasen 14a auf, damit das Buchsenteil 10 in seiner Lage eindeutig identifiziert werden kann. Eine solche Identifizierung ist notwendig, wenn das Buchsenteil 10 als SMD-Bauelement vollautomatisch in einer Fertigungsstraße auf eine Platine montiert bzw. gelötet wird.In the housing 12 sits an insulating part 14. This insulating part 14 is preferably clamped in the housing 12. This clamping holder is achieved, for example, by that the lower edge of the casing is caulked after the insulating member 14 is inserted into the housing 12 is. In addition, the insulating member 14 has one or more Identification lugs 14 a, so that the socket part 10 in its location can be clearly identified. Such Identification is necessary if the socket part 10 as Fully automatic SMD component in a production line a board is mounted or soldered.

Der konstruktive Aufbau der beiden in dem Isolierteil 14 sitzenden Kontaktteile 20 und 30 wird anhand der Figuren 4 und 5 deutlich. In Figur 4 ist das erste Kontaktteil 20 in perspektivischer Darstellung abgebildet. Das Kontaktteil 20 ist als u-förmige Kontaktfeder mit zwei Wandungen 21, 23 versehen, die einstückig von einer u-förmigen Wandung 22 verbunden sind. Die Wandungen 21, 23 liegen beabstandet zueinander parallel. An der in Figur 4 unteren Kante der Wandung 23 erstreckt sich rechtwinklig eine Anschlußplatte 25 entgegengesetzt zur Wandung 21 nach außen weg. An diese Anschlußplatte 25 ist beispielsweise der Antennenausgang der Elektronik eines Mobiltelefones angeschlossen. Hierfür sitzt das Buchsenteil 10 auf einer im Mobiltelefon untergebrachten Platine auf. Von der Wandung 23 der u-förmigen Kontaktfeder 20 erstreckt sich an der oberen Kante eine Haltenase 24 weg. Die andere Wandung 21 der u-förmigen Kontaktfeder 20 ist an ihrer oberen Kante mit einer schräg nach außen springenden Wandung 26 einstückig verbunden. Diese Wandung 26 dient als Einführhilfe und Anschlag für einen in das Buchsenteil 10 einzuführenden Kontaktstift 55. Insgesamt läßt sich über den u-förmigen Wandabschnitt 22 ein Hin- und Herfedern des Wandabschnitts 21 bewerkstelligen.The structural design of the two sitting in the insulating part 14 Contact parts 20 and 30 will be described with reference to FIGS. 4 and 5 clear. In FIG. 4, the first contact part 20 is in perspective Representation shown. The contact part 20 is as U-shaped contact spring provided with two walls 21, 23, which is integrally connected by a U-shaped wall 22 are. The walls 21, 23 are spaced from each other in parallel. At the lower edge in FIG. 4 of the wall 23 extends at right angles a connection plate 25 opposite to the wall 21 to the outside. To this connection plate 25 is the antenna output of the electronics, for example Mobile phones connected. For this sits the socket part 10 on a board housed in the mobile phone on. From the wall 23 of the U-shaped contact spring 20 extends at the upper edge of a retaining lug 24 away. The another wall 21 of the U-shaped contact spring 20 is at her upper edge with a sloping outward wall 26 integrally connected. This wall 26 serves as an insertion aid and stop for a to be introduced into the socket part 10 Contact pin 55. Overall, over the U-shaped Wall section 22 a spring-and-return of the wall portion 21 accomplish.

Das in Figur 5 ebenfalls in perspektivischer Darstellung abgebildete zweite Kontaktteil 30 verfügt über eine Anschlußplatte 31, an deren linken und rechten Außenkante beabstandet zueinander zwei Haltenasen 32, 33 nach oben wegspringen. An der links erkennbaren Haltenase 33 ist ein L-förmiger Wandabschnitt 34 einstückig angeformt. The likewise shown in Figure 5 in perspective second contact part 30 has a connection plate 31, spaced at the left and right outer edge to each other two retaining lugs 32, 33 jump upwards. At the left recognizable retaining lug 33 is an L-shaped wall portion 34 integrally formed.

Die u-förmige Kontaktfeder 20 und das zweite Kontaktteil 30 sind in der in Figur 2 und 3 dargestellten Weise in das Isolierteil 14 eingesteckt. Die Haltenasen 24, 32 und 33, die jeweils mit Widerhaken versehen sind, halten die Kontaktfeder 20 und das Kontaktteil 30 im Isolierteil 14 fest. Im nicht belastenden Zustand, d. h. bei nicht in das Buchsenteil 10 eingesetztem Steckerteil, besteht zwischen der u-förmigen Kontaktfeder 20 und dem zweiten Kontaktteil 30 eine elektrisch leitende Verbindung. Diese elektrisch leitende Verbindung wird dadurch bewirkt, dass sich die u-förmige Kontaktfeder 20 und das Kontaktteil 30 an den in den Figuren 4 und 5 jeweils mit K bezeichneten Kontaktstellen berühren.The U-shaped contact spring 20 and the second contact part 30 are in the manner shown in Figures 2 and 3 in the insulating part 14 inserted. The retaining lugs 24, 32 and 33, the each barbed, hold the contact spring 20 and the contact part 30 in the insulating part 14 fixed. I'm not burdening condition, d. H. not in the socket part 10 inserted plug part, consists of the U-shaped Contact spring 20 and the second contact part 30 an electrically conductive connection. This electrically conductive connection is caused by the U-shaped contact spring 20 and the contact part 30 to those in Figures 4 and 5 each contact designated K touch.

Wie bereits erläutert, ist im montierten Zustand des Buchsenteils 10 die Anschlußplatte 25 beispielsweise mit der Elektronik eines Mobiltelefones in Verbindung. Die elektrisch leitende Verbindung zwischen der Anschlußplatte 25 der u-förmigen Kontaktfeder 20 und der Anschlußplatte 31 des zweiten Kontaktteils 30 wird durch berührendes Anliegenden der Wandung 21 an der Wandung 34 des zweiten Kontaktteils 30 bewirkt. Hierfür liegt die Wandung 21 der u-förmigen Kontaktfeder 20 mit Federvorspannung an der Wandung 34 des zweiten Kontaktteils 30 an. Hierbei ist der Einbau der u-förmigen Kontaktfeder 20 innerhalb des Isolierteils 14 des Buchsenteiles 10 von entscheidender Bedeutung.As already explained, is in the assembled state of the female part 10, the connection plate 25, for example, with the electronics a mobile phone. The electric conductive connection between the connection plate 25 of the U-shaped Contact spring 20 and the connection plate 31 of the second Contact part 30 is by touching the wall 21 on the wall 34 of the second contact part 30 causes. For this purpose, the wall 21 of the U-shaped contact spring 20 with spring bias on the wall 34 of the second Contact part 30 on. Here is the installation of the u-shaped Contact spring 20 within the insulating part 14 of the female part 10 vital.

Die u-förmige Kontaktfeder 20 ist liegend in das Isolierteil 14 bzw. das Gehäuse 12 des Buchsenteiles 10 eingebaut. Liegend bedeutet dabei, dass eine gedachte Biegeachse, die in Figur 3 und Figur 4 mit B bezeichnet ist, parallel zur Steckrichtung liegt. Wird ein Kontaktstift in die Durchgangsöffnung entlang der Achse X des Buchsenteils 10 eingesetzt, führt dies dazu, dass der frei bewegliche Federschenkel der u-förmigen Kontaktfeder 20, d. h. die Wandung 21 mit der Einführhilfe 26 von der gegenüberliegenden Wandung 23 weggedrückt wird, so dass sich der berührende Kontakt zur Wandung 34 des zweiten Kontaktteils 30 löst. Bei in die Durchgangsöffnung des Buchsenteiles 10 eingesteckten Kontaktstift besteht daher keine elektrisch leitende Verbindung mehr zwischen der Anschlußplatte 25 und der Anschlußplatte 31. Die elektrisch leitende Verbindung besteht dann vielmehr zwischen der u-förmigen Kontaktfeder 20 und dem Kontaktstift selbst. Sofern der Kontaktstift mit einer externen Antenne in Verbindung steht, ist deshalb die Anschlußplatte 25 und damit die Elektronik eines Mobiltelefons an eine externe Antenne, die mit dem Kontaktstift in Verbindung steht, verbunden.The U-shaped contact spring 20 is lying in the insulating part 14 and the housing 12 of the female part 10 installed. reclining means that an imaginary bending axis, the in Figure 3 and Figure 4 is designated B, parallel to the plugging direction lies. If a contact pin in the through hole inserted along the axis X of the socket part 10, This leads to the fact that the freely movable spring leg of the U-shaped contact spring 20, d. H. the wall 21 with the insertion aid 26 pushed away from the opposite wall 23 becomes, so that the touching contact to the wall 34 of the second contact part 30 triggers. In the passage opening the female part 10 inserted contact pin Therefore, there is no more electrically conductive connection between the connection plate 25 and the connection plate 31. Die electrically conductive connection is then rather between the U-shaped contact spring 20 and the contact pin itself. Provided the contact pin is connected to an external antenna is, therefore, the connection plate 25 and thus the Electronics of a mobile phone to an external antenna, the connected to the contact pin connected.

In den Figuren 6 bis 8 ist ein für das oben beschriebene Buchsenteil 10 geeignetes Steckerteil 50 in Schnittdarstellung (vgl. Figur 6), in Seitenansicht (vgl. Figur 7) und in perspektivischer Darstellung gezeigt. Das Steckerteil 50, das im gezeigten Ausführungsbeispiel ein T-förmiges Gehäuse aufweist, verfügt mittig über einen Kontaktstift 55.
