Both connector pins (6, 11), arranged e.g. at a spacing of 2.54 mm, have a pressing-in zone (13), so that the bush part (1) can be mounted using press-fit technology to a printed-circuit board (12) which is used, for example, as a wiring rear wall. The metal housing of the complementary connector part contains a coaxial contact having a conventional solder terminal for a coaxial line. <IMAGE>

Description

Die Erfindung betrifft eine Steckkupplung für Koaxialleitungen, insbesondere für die Verwendung in Geräten der Nachrichtentechnik, zur Befestigung an einer gedruckten Leiterplatte, die beispielsweise in einem Baugruppenträger als Verdrahtungsrückwand dient.The invention relates to a plug-in coupling for coaxial lines, in particular for use in telecommunications equipment, for fastening to a printed circuit board, which is used, for example, in a subrack as a wiring rear wall.

Eine Steckkupplung ist bereits aus dem Entwurf für Steckverbinder der Bauform M nach DIN 41612/Teil 8 bekannt. Bei diesen primär für die Bestückung von Kontaktkammern der Isolierkörper von Steckerleisten für gedruckte Leiterplatten konzipierten Koaxialkontakten sind die Anschlußstifte als Lötanschlüsse ausgebildet und zur Steckrichtung rechtwinklig angeordnet. Die Steckachse der Koaxialkontakte erstrecken sich somit in der Einbaulage parallel zur Leiterplattenebene.A plug-in coupling is already known from the design for type M connectors according to DIN 41612 / Part 8. In these coaxial contacts designed primarily for the assembly of contact chambers of the insulating bodies of plug strips for printed circuit boards, the connection pins are designed as solder connections and are arranged at right angles to the direction of insertion. The plug axis of the coaxial contacts thus extend parallel to the PCB level in the installed position.

In der US-A-3 910 665 ist außerdem eine Steckvorrichtung für Koaxialkabel beschrieben, die vertikal auf einer gedruckten Leiterplatte montierbar ist. Die Steckvorrichtung besteht aus einem auf einer Seite der gedruckten Leiterplatte angeordneten Verbinderteil für die Aufnahme des mit einer Hülse versehenen Koaxialkabels und einer auf der anderen Seite der gedruckten Leiterplatte vorgesehenen Buchse, in welche der aus der Hülse hervorstehende blanke Mittelleiter des Koaxialkabels einsteckbar ist.In US-A-3 910 665 a connector for coaxial cable is also described, which can be mounted vertically on a printed circuit board. The plug device consists of a connector part arranged on one side of the printed circuit board for receiving the coaxial cable provided with a sleeve and a socket provided on the other side of the printed circuit board, into which the bare central conductor of the coaxial cable protruding from the sleeve can be inserted.

Bei der Hülse handelt es sich um ein aus Blech hergestelltes Stanzbiegeteil, das so auf das separat vorbereitete Kabelende aufgerollt wird, daß die Hülse das Schirmgeflecht kontaktiert und mit zwei Quetschlappen den Kabelmantel umfaßt. Das ebenfalls aus Blech gestanzte und buchsenartig geformte Verbinderteil hat um die Aufnahme für die Hülse des Koaxialkabels herum drei um 120° zueinander versetzte Laschen mit je einem Anschlußlappen. In montierter Lage stehen die Laschen hochkant auf der Leiterplatte und die Anschlußlappen sind in entsprechende Bohrungen eingelötet, wobei sie geerdete Leiterbahnen kontaktieren. Zwischen den drei Bohrungen enthält die Leiterplatte eine größere Öffnung, hinter welcher die Buchse der den Mittelleiter des Koaxialkabels aufnehmenden Steckvorrichtung angeordnet ist.The sleeve is a stamped and bent part made of sheet metal, which is rolled up onto the separately prepared cable end in such a way that the sleeve contacts the shielding braid and embraces the cable sheath with two squeeze flaps. The connector part, likewise stamped from sheet metal and shaped like a socket, has three tabs around the receptacle for the sleeve of the coaxial cable, each offset by 120 ° to one another, each with a connecting tab. In the assembled position, the tabs are upright on the circuit board and the connection tabs are soldered into corresponding holes, making contact with earthed conductor tracks. Between the three holes, the circuit board contains a larger opening, behind which the socket of the plug device receiving the center conductor of the coaxial cable is arranged.

Aus der EP 0 195 955 A1 ist ferner eine Leiterplatte bekannt, die von rasterförmig angeordneten Kontaktstiften durchsetzt ist. Die Leiterplatte stellt die Verdrahtungsrückwand eines Baugruppenträgers dar, in den von vorn mit Buchsenleisten versehene elektrische Baugruppen eingeschoben und dabei auf die innen vorstehenden Kontaktstifte gesteckt werden. Auf den an der Rückseite des Baugruppenträgers vorstehenden Teil der Kontaktstifte werden mit Leitungsdrähten verbundene Kabelstecker geschoben.A printed circuit board is also known from EP 0 195 955 A1, which is penetrated by contact pins arranged in a grid. The printed circuit board represents the wiring rear wall of a subrack, in the electrical assemblies provided with socket strips from the front and are inserted into the contact pins protruding from the inside Cable plugs connected to lead wires are pushed onto the part of the contact pins protruding from the rear of the rack.

Der Erfindung liegt die Aufgabe zugrunde, eine in Miniaturbauweise herstellbare Steckkupplung für eine in einem Baugruppenträger als Verdrahtungsrückwand verwendbare Leiterplatte zu schaffen, die einerseits eine Verbindung mit einem Koaxialkabel und andererseits Verbindungen mit zwei Kontaktelementen der Buchsenleiste einer herkömmlichen Baugruppe gestattet. Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen konstruktiven Maßnahmen gelöst. Weitere Ausgestaltungen der Steckkupplung sind den Unteransprüchen zu entnehmen.The invention has for its object to provide a plug-in coupling that can be produced in a miniature design for a circuit board that can be used in a rack as a wiring rear wall, which on the one hand allows a connection with a coaxial cable and on the other hand connections with two contact elements of the socket strip of a conventional assembly. This object is achieved by the constructive measures specified in claim 1. Further configurations of the plug-in coupling can be found in the subclaims.

Weitere Vorteile der Lösung sind in der Beschreibung erwähnt.Further advantages of the solution are mentioned in the description.

The invention will be explained in more detail with reference to an embodiment shown in the drawings as follows. The drawings show:
  • 1 shows the socket part of the plug-in coupling fastened in a printed circuit board, partly in longitudinal section;
  • Fig. 2 shows the socket part of Figure 1, in plan view.

In den Fig. 1 bis 3 ist das Buchsenteil der Miniatur-Steckkupplung mit 1 bezeichnet. Es besteht aus einem im wesentlichen hülsenförmigen Metallgehäuse 2 mit einer an der Basis seitlich abstehenden Lasche 3. Das Hülsenteil des Metallgehäuses 2 enthält einen im rückwärtigen Bereich vollständig in Isoliermaterial 4 eingebetteten Koaxialkontakt 5, dessen an der Rückseite aus dem Metallgehäuse 2 hervorstehendes Anschlußende als Steckerstift 6 und dessen in der oberen Hälfte des Hülsenteiles befindliches Verbindungsende als Buchsenkontakt ausgebildet ist.1 to 3, the socket part of the miniature plug-in coupling is designated by 1. It consists of an essentially sleeve-shaped metal housing 2 with a tab 3 projecting laterally from the base. The sleeve part of the metal housing 2 contains a coaxial contact 5 which is completely embedded in insulating material 4 in the rear area, the connection end of which protrudes from the metal housing 2 on the rear side as a plug pin 6 and whose connection end located in the upper half of the sleeve part is designed as a socket contact.

Im Metallgehäuse 2 wird der Koaxialkontakt 5 durch Einspritzen von Kunststoff befestigt, wobei in der oberen Hülsenhälfte ein Freiraum 7 ausgenommen bleibt, die Innenwand des Hülsenteiles jedoch eine Auskleidung mit Isoliermaterial 4 erhält. Zur Verhinderung von Rotations- und Axialbewegungen weist der Koaxialkontakt 5 ein Halteteil 8 auf, das z.B. aus seitlich ausgebildeten Lappen besteht. Aus dem selben Grund ist das Metallgehäuse 2 mit einer den Innendurchmesser des Hülsenteiles wenigstens teilweise reduzierenden Einschnürung 9 versehen, die außerdem zur Einrastung des komplementären Steckerteiles dient. Die Lasche 3 des Metallgehäuses 2 durchsetzt eine Öffnung 10, in welche das rückwärtige Ende eines dem Anschlußende des Koaxialkontaktes 5 gleichender Steckerstift 11 z.B. durch Einpressen, Löten oder Nieten etc. befestigt ist. Die Öffnung 10 hat einen dem Steckerstift 11 angepaßten Querschnitt, der rund oder eckig sein kann.The coaxial contact 5 is fastened in the metal housing 2 by injecting plastic, a space 7 being left open in the upper half of the sleeve, but the inner wall of the sleeve part being lined with insulating material 4. In order to prevent rotational and axial movements, the coaxial contact 5 has a holding part 8 which, for example, consists of tabs formed on the side. For the same reason, the metal housing 2 is provided with a constriction 9 which at least partially reduces the inside diameter of the sleeve part and which also serves to latch the complementary plug part. The tab 3 of the Metal housing 2 passes through an opening 10 into which the rear end of a connector pin 11 which is the same as the connection end of the coaxial contact 5 is fastened, for example by pressing, soldering or riveting, etc. The opening 10 has a cross section adapted to the plug pin 11, which can be round or angular.

Koaxialkontakte der beschriebenen Ausführung bilden die Schnittstelle von der ungeschirmten Vielpolstecktechnik zu einem Koaxialkabel-Stecksystem, das eine hohe Packungsdichte erlaubt. Daher sind die beiden Steckerstifte 6, 11 des Buchsenteiles 1 in einem dem Raster der Buchsenleiste einer Baugruppe entsprechenden Abstand angeordnet. Diesen Abstand, der beispielsweise 2,54 mm beträgt, haben auch entsprechende Bohrungen der im Baugruppenträger als Verdrahtungsrückwand verwendeten Leiterplatte 12, in deren Bohrungen das Buchsenteil 1 durch einfaches Einpressen der Steckerstifte 6 und 11 befestigt wird. Die beiden Steckerstifte 6, 11 sind hierfür mit je einer entsprechenden Einpreßzone 13 versehen, die unmittelbar hinter dem Metallgehäuse 2 angeordnet ist und die beide zusammen dem Buchsenteil 1 mechanisch einen festen Halt geben.Coaxial contacts of the described design form the interface from the unshielded multi-pole plug technology to a coaxial cable plug system, which allows a high packing density. Therefore, the two connector pins 6, 11 of the socket part 1 are arranged at a distance corresponding to the grid of the socket strip of an assembly. This distance, which is, for example, 2.54 mm, also has corresponding bores in the printed circuit board 12 used in the subrack as the wiring rear wall, in the bores of which the socket part 1 is fastened by simply pressing in the plug pins 6 and 11. For this purpose, the two connector pins 6, 11 are each provided with a corresponding press-in zone 13 which is arranged directly behind the metal housing 2 and which together give the socket part 1 a mechanical hold.

Die Befestigung des Buchsenteiles 1 geschieht in der Weise, daß die Steckerstifte 6, 11 sich auf der Baugruppenseite und das Metallgehäuse 2 auf der Kabelsteckseite befinden. Da das Metallgehäuse 2 vorzugsweise ein einstückiges Feingußteil aus Messing ist und die Kabelsteckseite der Leiterplatte 12 einen Erdungspotential aufweisenden Metallbelag 14 mit Aussparungen im Durchtrittsbereich des Koaxialkontaktes 5 hat, kann das Metallgehäuse 2 noch durch Löten mit dem Metallbelag 14 verbunden werden. Aus diesem Grund kann auch das in der Lasche 3 befestigte Ende des als 0-Volt-Stift dienenden Steckerstiftes 11 in der Öffnung 10 bedarfsweise noch zusätzlich mit dem Metallgehäuse 2 gelötet werden.The attachment of the socket part 1 is done in such a way that the connector pins 6, 11 are on the assembly side and the metal housing 2 on the cable plug side. Since the metal housing 2 is preferably a one-piece investment casting made of brass and the plug-in side of the printed circuit board 12 has a metal coating 14 with ground potential with cutouts in the passage area of the coaxial contact 5, the metal housing 2 can still be connected to the metal coating 14 by soldering. Because of this, can the end of the plug pin 11 serving as a 0 volt pin, which is fastened in the tab 3, can also be additionally soldered to the metal housing 2 in the opening 10, if necessary.

In den Fig. 3 bis 5 ist das Steckerteil der Miniatur-Steckkupplung mit 15 bezeichnet. Es besteht aus einem hülsenförmigen Metallgehäuse 16, das einen mittleren Abschnitt 17 mit reduziertem Innendurchmesser und in der Mitte des Abschnittes wieder eine geringe Erweiterung aufweist. In diesem Abschnitt 17 ist ein röhrchenförmiger, seitlich mit einem Halteteil 18 versehener Koaxialkontakt 19 durch Umspritzen mit Isoliermaterial 20 befestigt.3 to 5, the plug part of the miniature plug-in coupling is designated by 15. It consists of a sleeve-shaped metal housing 16 which has a central section 17 with a reduced inside diameter and again a slight widening in the middle of the section. In this section 17, a tubular coaxial contact 19, laterally provided with a holding part 18, is fastened by extrusion coating with insulating material 20.

In den Hohlraum 21 des röhrchenförmigen Koaxialkontaktes 19 wird beim Anschließen eines Koaxialkabels (nicht dargestellt) der Innenleiter eingelötet. Mehrere, die Wandung des Metallgehäuses 16 im rückwärtigen Hülsenteil 22 durchsetzende Öffnungen 23 dienen zur Herstellung von Lötverbindungen zwischen dem im Hülsenteil endenden Schirmmantel des Koaxialkabels und dem Gehäuse des Steckerteiles 15. Um eine elektrisch gut leitende und mechanisch feste Verbindung zu gewährleisten, ist der Innendurchmesser des rückwärtigen Hülsenteiles 22 dem Außendurchmesser des für den Anschluß vorgesehenen Koaxialkabels angepaßt.When connecting a coaxial cable (not shown), the inner conductor is soldered into the cavity 21 of the tubular coaxial contact 19. A plurality of openings 23 which penetrate the wall of the metal housing 16 in the rear sleeve part 22 serve to produce soldered connections between the shielding jacket of the coaxial cable ending in the sleeve part and the housing of the plug part 15 rear sleeve part 22 adapted to the outer diameter of the coaxial cable provided for the connection.

Der den Koaxialkontakt 19 schützende, vordere Hülsenteil 24 des Metallgehäuses 16 hat nahe der Einstecköffnung eine Einschnürung 25, deren konvex gewölbter Teil mit dem konkaven Teil der Einschnürung 9 des Buchsenteiles 1 korrespondiert. Außerdem ist das Hülsenteil 24 mit wenigstens einem, vorzugsweise jedoch mit mehreren am Umfang in gleichmäßigen Abständen verteilten Schlitzen 26 versehen, die sich in Axialrichtung des Metallgehäuses 16 erstrecken und federnde Finger bilden.The front sleeve part 24 of the metal housing 16 protecting the coaxial contact 19 has a constriction 25 near the insertion opening, the convex part of which corresponds to the concave part of the constriction 9 of the socket part 1. In addition, the sleeve part 24 with at least one, but preferably with several Provided circumferentially evenly spaced slots 26 which extend in the axial direction of the metal housing 16 and form resilient fingers.

In die von der Einschnürung 25 am vorderen Hülsenteil 24 gebildete Sicke ist ein Federring 27 eingesetzt. Dieser und die federnden Finger bewirken, daß die beiden Hälften der Miniatur-Steckkupplung beim Herstellen der Verbindung rastend miteinander in Eingriff kommen. Hierbei dringt der vordere Rand vom Metallgehäuse 2 des Buchsenteiles 1 in eine entsprechende Ringnut 28 im Metallgehäuse 16 des Steckerteiles 15 ein und füllt diese vollständig aus. Die Ringnut 28 ist an der Steckseite im mittleren Abschnitt 17 des Metallgehäuses 16 angeordnet. Der gegenüber dem Isoliermaterial 20 etwas vorstehende Gehäuserand und die Ringnut 28 bilden somit eine wirksame Abdichtung gegen elektromagnetische Störstrahlung.A spring ring 27 is inserted into the bead formed by the constriction 25 on the front sleeve part 24. This and the resilient fingers cause the two halves of the miniature plug-in coupling to engage with one another when the connection is made. Here, the front edge penetrates from the metal housing 2 of the socket part 1 into a corresponding annular groove 28 in the metal housing 16 of the plug part 15 and fills it completely. The annular groove 28 is arranged on the plug side in the middle section 17 of the metal housing 16. The housing edge slightly protruding from the insulating material 20 and the annular groove 28 thus form an effective seal against electromagnetic interference radiation.

Die Miniatur-Steckkupplung ist mit äußerst kleinen Abmessungen herstellbar. So beträgt beispielsweise der Durchmesser des Metallgehäuses 2 vom Buchsenteil 1 in dem den Koaxialkontakt 5 enthaltenden zylindrischen Bereich ca. 2.5 mm und der Durchmesser des Metallgehäuses 16 vom Steckerteil 15 nur ca. 3 mm; die Länge des Buchsenteiles 1 ca. 7 mm und die des Steckerteiles 15 ca. 11 mm. Diese geringen Abmessungen gestatten es, mehrere Steckerteile 15 in einem als Kabelstecker ausgebildeten Isolierkörper zu befestigen. Auf diese Weise können je nach Bedarf Kabelstecker mit verschiedenen Polzahlen hergestellt werden, die mit den an der Verdrahtungsrückwand eines Baugruppenträgers befestigten Buchsenteilen 1 verbindbar sind.The miniature plug-in coupling can be manufactured with extremely small dimensions. For example, the diameter of the metal housing 2 from the socket part 1 in the cylindrical region containing the coaxial contact 5 is approximately 2.5 mm and the diameter of the metal housing 16 from the plug part 15 is only approximately 3 mm; the length of the socket part 1 approx. 7 mm and that of the plug part 15 approx. 11 mm. These small dimensions allow several plug parts 15 to be fastened in an insulating body designed as a cable plug. In this way, cable plugs with different numbers of poles can be produced as required, which can be connected to the socket parts 1 fastened to the rear wiring wall of a subrack.
