The base of the plug (1) also has slits (4) around the plug and the screen elements are laid in these. The screen elements are formed of transverse (13) and long (14) screen plates. Those plates (13,14) in the front of the chambers (11) are provided with cuts of given width with the corners bent in a given direction. Thin contact pins (3) are anchored in the plug strip (1) at the plate cross-points and connected to earth. These pins (3) contact the screen plates (13,14) at four points.

Description

Die vorliegende Erfindung betrifft einen Steckverbinder für Rückwandverdrahtungen, bestehend aus einer als einseitig offenes rechtwinkliges Gehäuse ausgebildeten Messerleiste zum Aufstecken auf die Messer einer Rückwandleiterplatte und einer in die Messerleiste einsteckbaren mit Aufnahmekammern versehenen und mit einer Baugruppenleiterplatte fest verbundenen Federleiste, wobei die Messer und Federn parallel in mehreren Reihen angeordnet sind, wobei die Wände der Aufnahmekammern mit Schlitzen versehen sind, welche die Aufnahmekammern umgeben und in die elektrisch leitfähige Schirmelemente eingelegt sind, die untereinander leitend zu einem Potentialkäfig verbunden sind, und wobei der Boden der Messerleiste mit Schlitzen versehen ist, welche die Messer umgeben und in die elektrisch leitfähige Schirmelemente eingelegt sind.The present invention relates to a connector for backplane wiring, consisting of a male connector designed as a one-sided open right-angled housing for plugging onto the knives of a rear panel circuit board and a female connector which can be inserted into the male connector with receiving chambers and is firmly connected to a module circuit board, the knives and springs being parallel in several rows are arranged, the walls of the receiving chambers being provided with slots which surround the receiving chambers and inserted into the electrically conductive shielding elements which are conductively connected to one another to form a potential cage, and wherein the bottom of the male connector is provided with slots which the Knives surround and in which electrically conductive shield elements are inserted.

Ein derartiger Steckverbinder wurde bereits in der deutschen Patentanmeldung 4 313 771 vorgeschlagen. Der vorgeschlagene Steckverbinder weist bei hohen Übertragungsfrequenzen gegenüber den herkömmlichen Steckverbindern verbesserte Hochfrequenzeigenschaften auf. Diese verbesserten Hochfrequenzeigenschaften genügen aber nicht allen Anforderungen.Such a connector has already been proposed in German patent application 4,313,771. At high transmission frequencies, the proposed connector has improved high-frequency properties compared to conventional connectors. However, these improved high-frequency properties do not meet all requirements.

Aufgabe der vorliegenden Erfindung ist es, einen Steckverbinder der eingangs genannten Art anzugeben, dessen Hochfrequenzeigenschaften allen zur Zeit gestellten Anforderungen genügen.The object of the present invention is to provide a connector of the type mentioned at the outset, the high-frequency properties of which meet all the requirements currently set.

Diese Aufgabe wird für einen Steckverbinder der eingangs genannten Art dadurch gelost, daß die Schirmelemente der Federleiste aus ineinander einschiebbaren kammartig ausgebildeten Schirmungsquerblechen und Schirmungslängsblechen bestehen, wobei alle Schirmungsbleche im vorderen Bereich der Aufnahmekammern mit Einschneidungen vorgegebener Breite versehen sind und die jeweiligen Ecken in eine vorgegebene Richtung abgebogen sind, und daß an den Kreuzungspunkten der Schirmelemente in der Messerleiste verankerte und mit Masse verbundene dünne zusätzliche Kontaktstifte vorgesehen sind, welche die Schirmungsbleche der Federleiste im vorderen Bereich der Aufnahmekammern kontaktieren.This object is achieved for a plug connector of the type mentioned at the outset in that the shielding elements of the female connector consist of combable shielding transverse sheets and longitudinal shielding sheets which can be inserted into one another, wherein all shielding plates in the front area of the receiving chambers are provided with incisions of a predetermined width and the respective corners are bent in a predetermined direction, and that at the intersection of the shielding elements anchored in the male connector and connected to ground thin additional contact pins are provided, which the shielding plates Contact female connector in the front area of the receiving chambers.

Bei dem erfindungsgemäßen Steckverbinder werden die im Zwischenraster angeordneten Schirmelemente auf die entsprechenden Leiterplatten mittels der zusätzlichen Kontaktstifte ankontaktiert. Hierdurch wird eine KOAX-Funktion ermöglicht, welche gegenüber der herkömmlichen KOAX-Steckverbinderausführung billiger ist und dem erfindungsgemäßen Steckverbinder Hochfrequenzeigenschaften verleiht, welche allen heutigen Anforderungen genügen.In the connector according to the invention, the shielding elements arranged in the intermediate grid are contacted on the corresponding printed circuit boards by means of the additional contact pins. This enables a KOAX function, which is cheaper than the conventional KOAX connector design and gives the connector according to the invention high-frequency properties which meet all of today's requirements.

Eine zweckmäßige Ausgestaltung des erfindungsgemäßen Steckverbinders ist dadurch gekennzeichnet, daß die Schirmelemente der Messerleiste aus ineinander einschiebbaren kammartig ausgebildeten Schirmungsblechstreifen bestehen, welche im wesentlichen wellenförmig gebogen sind, damit an den Kreuzungspunkten ein federnder Kontakt mit den Kontaktstiften gegeben ist. Auf diese Weise wird auch innerhalb des Messerleistenbodens eine sehr gute Abschirmung der signalführenden Messer erreicht.An expedient embodiment of the connector according to the invention is characterized in that the shielding elements of the male connector consist of combable shielding sheet metal strips which can be pushed into one another and which are bent essentially in a wave-like manner, so that there is resilient contact with the contact pins at the crossing points. In this way, very good shielding of the signal-carrying knives is also achieved within the bottom of the male connector.

Um auch bei Steckverbindern, bei denen die Anschlüsse der Federleiste rechtwinklig abgebogen sind, gute hochfrequenzmäßige Eigenschaften zu erreichen, ist eine andere Ausgestaltung des erfindungsgemäßen Steckverbinders dadurch gekennzeichnet, daß die Schirmungsbleche rechtwinklig abgebogen sind, wobei der erste Schenkel parallel zur Längsrichtung der Aufnahmekammern und der zweite Schenkel senkrecht zur Leiterplatte verläuft, und daß die Schirmlängsbleche im Winkelbereich durch isolierende Winkelprofile getrennt sind.In order to achieve good high-frequency properties even with connectors in which the connections of the female connector are bent at right angles, another embodiment of the connector according to the invention is characterized in that the shielding plates are bent at right angles, the first leg parallel to the longitudinal direction of the receiving chambers and the second Leg runs perpendicular to the circuit board, and that the longitudinal shield plates are separated in the angular range by insulating angle profiles.

Weitere Ausgestaltungen des erfindungsgemäßen Steckverbinders ergeben sich aus den weiteren Unteransprüchen sowie aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Figur.Further refinements of the connector according to the invention result from the further subclaims and from the following description of an exemplary embodiment with reference to the figure.

Fig. 1 zeigt unter anderem eine teilweise Draufsicht auf eine Potentialebene der Rückwandleiterplatte 6 mit den größeren Bohrungen 18 für die Kontaktmesser und den kleineren Bohrungen 19 für die Kontaktstifte der Schirmung. Der andere Teil der Fig. 1 zeigt eine teilweise Draufsicht auf ein Messerleistengehäuse 1, welches auf die Rückwandleiterplatte 6 aufgesteckt worden ist. Zwischen den Kontaktmessern 2 sind Schlitze 4 im Messerleistenboden des Messerleistengehäuses 1 vorgesehen. In diese Schlitze sind federnde Schirmungsblechstreifen 5 eingelegt. Die Schirmungsblechstreifen 5 sind kammartig ausgebildet, damit sie ineinander geschoben werden können. Dabei können, wie in der Zeichnung dargestellt ist, die Schirmungsblechstreifen 5 im wesentlichen wellenförmig gebogen werden, damit sie kraftschlüssig an den Kontaktstiften 3 anliegen und somit ein sicherer Kontakt gewährleistet ist. Die Kontaktstifte 3 werden im Kunststoffkörper der Messerleiste gehalten und über das von den Schirmungsblechstreifen 5 gebildete Blechgefache miteinander verbunden. Damit der Kunststoffkörper nicht auseinanderfällt, ist ein zusammenhängender Boden von ca. 1mm notwendig.1 shows, among other things, a partial top view of a potential level of the backplane 6 with the larger holes 18 for the contact blades and the smaller holes 19 for the contact pins of the shield. The other part of FIG. 1 shows a partial top view of a male connector housing 1, which has been plugged onto the backplane 6. Between the contact blades 2, slots 4 are provided in the bottom of the male header of the male housing 1. Resilient shielding sheet strips 5 are inserted into these slots. The shielding sheet strips 5 are comb-shaped so that they can be pushed into one another. Here, as shown in the drawing, the shielding sheet strips 5 can be bent essentially in a wave-shaped manner so that they rest non-positively on the contact pins 3 and thus secure contact is ensured. The contact pins 3 are held in the plastic body of the male connector and connected to one another via the sheet metal compartment formed by the shielding sheet metal strips 5. So that the plastic body does not fall apart, a continuous floor of approx. 1mm is necessary.

Fig. 2 zeigt einen teilweisen Schnitt durch ein Messerleistengehäuse 1 in Verbindung mit einer teilweisen Draufsicht auf das Messerleistengehäuse 1, wie es in Fig. 1 dargestellt ist. Weiterhin ist in Fig. 2 der Zusammenhang mit dem Federleistengehäuse 8, welches in das Messerleistengehäuse 1 eingeschoben wird, dargestellt.FIG. 2 shows a partial section through a male connector housing 1 in conjunction with a partial plan view of the male connector housing 1, as shown in FIG. 1. Furthermore, the relationship with the female connector housing 8, which is inserted into the male connector housing 1, is shown in FIG. 2.

Der Aufbau des Federleistengehäuses 8 ergibt sich aus Fig. 3, in welcher ein Querschnitt durch ein Federleistengehäuse gezeigt ist, bei welchem die Anschlüsse rechtwinklig zur Leiterplatte hin abgebogen sind, in Verbindung mit den Fig. 4 und 5, welche Schnitte entlang der Linien A-A und B-B in Fig. 3 darstellen.The structure of the female connector 8 is shown in Fig. 3, in which a cross section through a female connector is shown, in which the connections are bent at right angles to the circuit board, in connection with Figs. 4 and 5, which sections along the lines AA and Represent BB in Fig. 3.

In dem Federleistengehäuse 8 sind Aufnahmekammern 11 für die Kontaktfedern 10 vorgesehen. Die Kontaktfedern sind mit Einpreßstiften 15 verbunden, durch welche sie mit der Baugruppenleiterplatte 9 kontaktiert sind. Innerhalb des Federleistengehäuses 8 sind in Schlitzen 12 zwischen den Aufnahmekammern 11 Schirmungslängsbleche 13 und Schirmungsquerbleche 14 angeordnet. Diese Schirmungsbleche 13 und 14 sind im wesentlichen kammartig ausgebildet und besitzen im vorderen Bereich der Aufnahmekammern Einschneidungen vorgegebener Breite, wobei die jeweiligen Ecken der Einschneidungen in eine vorgegebene Richtung abgebogen sind, was im Detail in der Fig. 7 dargestellt ist.In the female connector housing 8, receiving chambers 11 are provided for the contact springs 10. The contact springs are connected to press-in pins 15, by means of which they are contacted with the assembly circuit board 9.

These shielding plates 13 and 14 are essentially formed like a comb and have incisions of a predetermined width in the front region of the receiving chambers, the respective corners of the incisions being bent in a predetermined direction, which is shown in detail in FIG. 7.

Der Aufbau und die Anordnung der Schirmungslängsbleche 13 und der Schirmungsquerbleche 14 ergibt sich aus der Fig. 6. In der Fig. 6 sind abgewinkelte Schirmungslängsbleche 13 gezeigt, es ist aber aus dieser Fig. leicht zu ersehen, wie die Schirmungslängsbleche 13 ausgeführt sind, wenn das Federleistengehäuse 8 einen graden Durchgang aufweist. Die abgewinkelten Schirmungslängsbleche 13 weisen in ihrem Schenkel, welcher senkrecht zur Baugruppenleiterplatte steht, Langlöcher auf, in welche Lappen der Schirmungsbleche 14, von denen in Fig. 6 nur eines dargestellt ist, hindurchragen, um einen guten Kontakt zwischen den Schirmungsblechen zu gewährleisten. Diese Lappen werden nach dem Durchstecken umgebogen.The structure and the arrangement of the longitudinal shielding plates 13 and the transverse shielding plates 14 can be seen in FIG. 6.
