STAND DER TECHNIKSTATE OF THE ART

In der Automobilindustrie werden in die Fahrzeuge zunehmend HF-SystemeIn the automotive industry, vehicles are increasingly becoming HF systems

(GPS, Aussenantenne für Mobilfunk, Autoradio etc.) integriert, für die im Fahrzeug Koaxialkabel verlegt und angeschlossen werden müssen. Für derartige koaxiale Auto-Steckverbinder sind in den USA und in Europa Normen eingeführt worden, um Systeme unterschiedlicher Zulieferer miteinander kompatibel zu machen. In den USA existiert die Norm SAE/USCAR-18, der in Europa die Norm DIN 72594-1 (FAKRA) entspricht. International gilt die Norm ISO-20860-1.Integrated (GPS, outdoor antenna for mobile radio, car radio, etc.) for the coaxial cable to be installed and connected in the vehicle. For such coaxial Automotive connectors have been introduced in the US and Europe to make systems from different suppliers compatible. In the USA, there is the SAE / USCAR-18 standard, which complies with the European standard DIN 72594-1 (FAKRA). International standard ISO-20860-1 applies.

Von der Anmelderin werden in diesem Zusammenhang bereits automobile Steckverbinder angeboten, die unter der Bezeichnung ARC (Automotive Radiofrequency Connectors) zusammengefasst werden, und die als HF- Steckverbinderfamilie speziell für Telematik-, Multimedia-, Safety- und Security- Anwendungen in Automobilen und LKWs entwickelt worden sind.In this context, the applicant already offers automotive connectors, which are grouped under the name ARC (Automotive Radiofrequency Connectors), and which, as an HF connector family, are specially developed for telematics, multimedia, safety and security applications in automobiles and trucks have been.

Innerhalb dieser Familie gibt es Winkelsteckverbinder, bei denen das zu verbindende Koaxialkabel in der Regel um 90° abgewinkelt zur Steckrichtung bzw. Steckerachse in den Steckverbinder eingeführt wird.Within this family, there are angle connectors in which the coaxial cable to be connected is usually introduced at 90 ° angled to the direction of insertion or connector axis in the connector.

Bei derartigen abgewinkelten Steckverbindern ist der Innenleiter üblicherweise aus zwei Kontaktstücken zusammengesetzt, die bei der Montage des Steckverbinders senkrecht zueinander orientiert ineinander gesteckt werden. Dazu ist das in Steckrichtung orientierte erste Kontaktstück, das als massives Drehteil ausgebildet ist, am Ende mit einer Gabel versehen, in die senkrecht dazu ein mit dem Innenleiter des Koaxialkabels verbundener stiftartiges zweites Kontaktstück eingesteckt wird. Derartige Winkelsteckverbinder für den automobilen Bereich sind beispielsweise in der DE-A1-10 2004 041 809 oder der DE-B3-103 39 965 offenbart.In such angled connectors, the inner conductor is usually composed of two contact pieces, which are inserted into each other in the assembly of the connector oriented perpendicular to each other. For this purpose, the oriented in the insertion direction first contact piece, which is designed as a solid rotary part, provided at the end with a fork, in the perpendicular to a connected to the inner conductor of the coaxial cable pin-like second contact piece is inserted. Such angle connectors for the automotive sector are disclosed for example in DE-A1-10 2004 041 809 or DE-B3-103 39 965.

Die aus den zwei Kontaktstücken gebildete Kontaktvorrichtung stellt das Kernstück eines solchen Steckverbinders dar. Sie soll einerseits leicht und kostengünstig in grossen Stückzahlen herstellbar sein. Andererseits soll die Montage des Steckverbinders einfach und zuverlässig und im Hinblick auf die koaxiale Geometrie mit gleich bleibender Präzision möglich sein. Schliesslich soll die Kontaktvorrichtung auch unter erschwerten Umweltbedingungen, insbesondere stossartigen Erschütterungen und frequenzvariablen Vibrationen, wie sie im Automobilbereich vorkommen, sicher und ohne Einbussen am Funktionsumfang funktionieren.The contact device formed from the two contact pieces represents the core of such a connector. It should on the one hand be easy and inexpensive to produce in large quantities. On the other hand, the assembly of the connector should be simple and reliable and with regard to the coaxial geometry with constant precision possible. Finally, the contact device should also be used under difficult environmental conditions, in particular shock-like vibrations and variable-frequency vibrations, as they occur in the automotive sector, work safely and without loss of functionality.

Aus dem Bereich der elektrischen Anschlüsse sind unter der Bezeichnung „push- in connectors" Vorrichtungen bekannt, bei denen elektrische Leiter beim Einstecken in eine entsprechende Aufnahmevorrichtung eine Klemmzunge federnd beiseite schieben, die sich nach dem Einstecken an den elektrischen Leiter klemmend anlegt und ein Herausziehen des Leiters verhindert (siehe z.B. die US-A1 -2005/0282429 oder die US-A-6,080,008 oder die US-A-4,824,395 oder die US-A-4,397,514 oder, die US-A-3,945,711 ). Diese bekannten Vorrichtungen sind jedoch sehr aufwändig in Konstruktion und Montage, sind für einen rechtwinkligen Steckverbinder nicht besonders geeignet, und sind nicht optimal an eine koaxiale Leitergeometrie angepasst.From the field of electrical connections are known under the name "push-in connectors" devices in which electrical conductors when plugged into a corresponding receiving device push a clamping tongue resiliently aside, which applies after insertion to the electrical conductor by clamping and pulling out of Conductor (see eg US-A1 -2005 / 0282429 or US-A-6,080,008 or US-A-4,824,395 or US-A-4,397,514 or US-A-3,945,711), but these known devices are very complex in construction and assembly, are not particularly suitable for a rectangular connector, and are not optimally adapted to a coaxial conductor geometry.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es ist daher Aufgabe der Erfindung, eine Kontaktvorrichtung zu schaffen, die für den Einsatz als Innenleiter in den eingangs genannten Winkelsteckern besonders geeignet ist, und die genannten Forderungen erfüllt, sowie einen Steckverbinder mit einer solchen Kontaktvorrichtung und ein Verfahren zu dessen Montage anzugeben.It is therefore an object of the invention to provide a contact device, which is particularly suitable for use as an inner conductor in the above-mentioned angle plugs, and meets the above requirements, and to provide a connector with such a contact device and a method for its assembly.

Die Aufgabe wird durch die Gesamtheit der Merkmale der Ansprüche 1 , 10 und 15 gelöst. Wesentlich für die Kontaktvorrichtung nach der Erfindung ist eine Klemmvorrichtung mit einer federnden Klemmzunge, welche schräg zur Einsteckrichtung angeordnet ist und beim Einstecken des zweiten Kontaktstücks federnd zurückweicht, wobei die Klemmvorrichtung ein in Einsteckrichtung vor der Klemmzunge angeordnetes Führungsteil mit einem ersten Loch umfasst, und die Klemmzunge ein zweites Loch aufweist, derart, dass das zweite Kontaktstück beim Einstecken in das erste Kontaktstück durch beide Löcher hindurch gesteckt wird. Durch diese Konfiguration wird auf besonders einfache Weise eine präzise und sichere Dreipunktlagerung des zweiten Kontaktstücks im ersten Kontaktstück herbeigeführt, die einen genau definierten und sicheren Sitz der Kontaktvorrichtung auch bei schwierigen Umweltbedingungen gewährleistet.The object is solved by the totality of the features of claims 1, 10 and 15. Essential for the contact device according to the invention is a clamping device with a resilient clamping tongue, which is arranged obliquely to the insertion and resiliently recedes when inserting the second contact piece, wherein the clamping device comprises a arranged in the insertion direction in front of the clamping tongue guide member having a first hole, and the clamping tongue has a second hole, such that the second contact piece is inserted through both holes during insertion into the first contact piece. This configuration is a particularly simple way to a precise and safe three-point mounting of the second contact piece brought about in the first contact piece, which ensures a well-defined and secure fit of the contact device even in difficult environmental conditions.

Im den beiden rechtwinklig zueinander abgewinkelten Teilen des Aussenleiters 35 sind rechtwinklig zueinander zwei Kontaktstücke 10 und 20 angeordnet, die ineinander gesteckt eine Kontaktvorrichtung 30 gemäss Fig. 3-5 bilden. Die beiden Kontaktsstücke 10 und 20 sind in den beiden Armen des Aussenleiters 35 jeweils konzentrisch gelagert und bilden den Innenleiter des koaxialen Steckverbinders 40. Das erste Kontaktstück 10, das in den Fig. 1 und 2 für sich allein im Detail dargestellt ist, ist ein einstückiges Stanzbiegeteil aus einem elektrisch gut leitenden, oberflächenveredelten Metallblech mit guten Federeigenschaften. Es ist mittels eines in den Aussenleiter 35 eingeschobenen Dielektrikums 37 konzentrisch gelagert und ist durch eine dreieckige Querschnittskontur gegen ein Verdrehen um die Längsachse 19 gesichert.In the two mutually perpendicular angled parts of the outer conductor 35 are at right angles to each other two contact pieces 10 and 20 are arranged, which plug into each other form a contact device 30 as shown in FIG. 3-5. The two contact pieces 10 and 20 are each mounted concentrically in the two arms of the outer conductor 35 and form the inner conductor of the coaxial connector 40. The first contact piece 10, which is shown in FIGS. 1 and 2 alone in detail, is a one-piece Punching and bending part made of a highly electrically conductive, surface-finished metal sheet with good spring properties. It is mounted concentrically by means of a dielectric 37 inserted into the outer conductor 35 and is secured against rotation about the longitudinal axis 19 by a triangular cross-sectional contour.

Das erste Kontaktstück 10 hat einen sich entlang der Längsachse 19 erstreckenden, länglichen Körper 11 , an dessen einem Ende (in Fig. 1 rechts) eine Klemmvorrichtung 14 und an dessen anderem Ende (in Fig. 1 links) ein Buchsenteil 12 angeordnet sind. Der Buchsenteil 12 wird durch drei axial orientierte, um jeweils 120° versetzt angeordnete Kontaktfedern 13 gebildet und nimmt beim Steckvorgang einen im Gegenstück zum Steckverbinder 40 vorhandenen zentralen Stift in sich auf. Der Körper 11 kann im Bereich zwischen der Klemmvorrichtung 14 und dem Buchsenteil 12 grundsätzlich aber auch eine runde Querschnittskontur aufweisen.The first contact piece 10 has an elongated body 11 extending along the longitudinal axis 19, a clamping device 14 at one end thereof (on the right in FIG. 1) and a clamping device 14 at the other end (left in FIG. 1) Socket part 12 are arranged. The female part 12 is formed by three axially oriented, offset by 120 ° arranged contact springs 13 and takes during the insertion process in the counterpart to the connector 40 existing central pin in it. The body 11 may, in principle, also have a round cross-sectional contour in the area between the clamping device 14 and the socket part 12.

Die Klemmvorrichtung 14 besteht aus zwei Blechzungen 15 und 16. Die untere Blechzunge 15 dient als Führungsteil. Sie hat ein kreisrundes Loch 17, in welches beim Zusammenstecken der Kontaktvorrichtung 30 das zweite Kontaktstück 20 mit einem vorderen Steckerteil 21 eingeführt wird. Das Führungsteil 15 ist dabei quer zur Einsteckrichtung des zweiten Kontaktstücks 20 orientiert. Oberhalb des Führungsteils 15 ist schräg zur Einsteckrichtung (Längsachse 19' in Fig. 4) als zweite Blechzunge ein Klemmzunge 16 angeordnet, die ebenfalls ein kreisrundes Loch 18 aufweist. Die beiden Löcher 17 und 18 in den Zungen 15 und 16 liegen näherungsweise übereinander, so dass das zweite Kontaktstück 20 - begünstigt durch eine konische Spitze 26 am vorderen Ende des Steckerteils 21 - ohne Schwierigkeiten gemäss Fig. 3-5 nacheinander in die beiden Löcher 17 und 18 eingeführt werden kann (siehe Pfeil in Fig. 3).The clamping device 14 consists of two sheet metal tongues 15 and 16. The lower sheet metal tongue 15 serves as a guide part. It has a circular hole 17, in which when mating the contact device 30, the second contact piece 20 is inserted with a front plug part 21. The guide member 15 is oriented transversely to the insertion direction of the second contact piece 20. Above the guide member 15 is obliquely to the insertion direction (longitudinal axis 19 'in Fig. 4) as a second tongue tongue a clamping tongue 16 is arranged, which also has a circular hole 18. The two holes 17 and 18 in the tongues 15 and 16 are approximately one above the other, so that the second contact piece 20 - favored by a conical tip 26 at the front end of the plug part 21 - without difficulty as shown in FIG. 3-5 successively in the two holes 17th and 18 can be introduced (see arrow in Fig. 3).

Beim Einführen des zweiten Kontaktteils 20 in die Klemmvorrichtung 14 wird die schräg stehende Klemmzunge 16 mit dem freien Ende elastisch federnd nach oben gebogen, so dass das zweite Kontaktstück 20 weitgehend ungehindert durch das zweite Loch 18 geschoben werden kann, bis es mit der Spitze 26 im Bereich einer Bohrung 38 am Dielektrikum 37 anstösst (Fig. 8b). Durch die Rückstellkraft fasst die Klemmzunge 16 das zweite Kontaktstück 20 an zwei Punkten (P1 und P2 in Fig. 3) und drückt es an einem dritten Punkt (P3 in Fig. 3) gegen den inneren Rand des Loches 17. Das zweite Kontaktstück 20 ist so in der Klemmvorrichtung 14 in einer präzisen und stabilen Dreipunktlagerung gehalten. Soll das zweite Kontaktstück 20 wieder herausgezogen werden, verklemmt sich die Klemmzunge 16 am Steckerteil 21 und, verhindert sicher ein Herausziehen. Das zweite Kontaktstück 20 erstreckt sich entlang der Längsachse 19' (Fig. 4a). Am einen Ende ist der bereits erwähnte, näherungsweise zylindrische Steckerteil 21 zum Einstecken in das erste Kontaktstück 10 ausgebildet. Am anderen Ende weist das zweite Kontaktstück einen Anschlussteil 22 zum Anschliessen des Innenleiters 28 eines Koaxialkabels 27 auf, das in üblicher Weise aus Innenleiter 28, Dielektrikum 29, Aussenleiter 31 und Aussenmantel 32 aufgebaut ist. Auch das zweite Kontaktstück 20 ist vorzugsweise ein einstückiges Stanzbiegeteil. Der Anschlussteil 22 umfasst zum Herstellen einer Crimpverbindung mit dem Kabel 27 zwei nach innen umbiegbare Crimplaschen 23, 24 (Fig. 5). Zwischen den Crimplaschen 23, 24 sind zur Verstärkung der Haltekraft in Längsrichtung hintereinander mehrere geprägte Rippen 25 vorgesehen.When inserting the second contact part 20 in the clamping device 14, the inclined clamping tongue 16 is elastically resiliently bent upward with the free end, so that the second contact piece 20 can be pushed through the second hole 18 largely unhindered until it with the tip 26 in the Area of a bore 38 on the dielectric 37 abuts (Fig. 8b). By the restoring force, the clamping tongue 16 grips the second contact piece 20 at two points (P1 and P2 in FIG. 3) and presses it against the inner edge of the hole 17 at a third point (P3 in FIG. 3). The second contact piece 20 is so held in the clamping device 14 in a precise and stable three-point bearing. If the second contact piece 20 are to be pulled out again, the clamping tongue 16 jams on the plug part 21 and securely prevents it from being pulled out. The second contact piece 20 extends along the longitudinal axis 19 '(FIG. 4a). At one end of the already mentioned, approximately cylindrical connector part 21 is formed for insertion into the first contact piece 10. At the other end, the second contact piece has a connection part 22 for connecting the inner conductor 28 of a coaxial cable 27, which is constructed in the usual way from inner conductor 28, dielectric 29, outer conductor 31 and outer jacket 32. Also, the second contact piece 20 is preferably a one-piece stamped and bent part. The connecting part 22 comprises two crimps 23, 24 (FIG. 5) which can be bent inwards to produce a crimped connection with the cable 27. Between the Crimplaschen 23, 24 a plurality of embossed ribs 25 are provided to reinforce the holding force in the longitudinal direction one behind the other.
