Description

Die Erfindung betrifft eine Anordnung zur Verbindung einer Rückwandleiterplatte mit Baugruppenleiterplatten, wobei einzelne in einem Gehäuse angeordnete Kontaktdurchgänge von elektrisch leitfähigen Schirmblechen umgeben sind, welche mit in einem Zwischenraster sowohl rückwandseitig als auch baugruppenseitig angebrachten Schirmpotential führenden Kontaktierungen verbunden sind.The invention relates to an arrangement for connecting a Backplane circuit board with assembly circuit boards, whereby individual contact passages arranged in a housing electrically conductive shield plates are surrounded, which with in an intermediate grid both on the rear wall and on the assembly side attached shielding potential leading contacts are connected.

Eine derartige Anordnung zur Verbindung einer Rückwandleiterplatte mit Baugruppenleiterplatten, bei welcher eine Schirmung, wie oben angegeben, im Zwischenraster erfolgt, ist z.B. in der europäischen Patentanmeldung 94 103 192 vorgeschlagen worden. Bei dieser bekannten Anordnung erfolgt die Verbindung zwischen der Rückwandleiterplatte und der eigentlichen Verbindungsanordnung über in in die Rückwandleiterplatte eingepreßte Messer, welche mit in dem Verbindungsgehäuse untergebrachten Kontaktfedern kontaktieren. Derartige in die Rückwandleiterplatte eingepreßte Messer führen bei sehr hohen Übertragungsfrequenzen im Gigaherzbereich zu einem nicht optimalen Übertragungsverhalten der Verbindungsanordnung.Such an arrangement for connecting a backplane with assembly circuit boards, where shielding, as indicated above, is done in the intermediate grid, e.g. proposed in European patent application 94 103 192 been. In this known arrangement, the connection is made between the backplane and the actual connection arrangement via pressed into the backplane Knives, which are housed in the connection housing Contact contact springs. Such in the backplane Pressed-in knives lead at very high Transmission frequencies in the gigahertz range at a non-optimal Transmission behavior of the connection arrangement.

Die Aufgabe der vorliegenden Erfindung besteht daher darin, eine Verbindungsanordnung der eingangs genannten Art zu schaffen, bei der auch bei sehr hohen Übertragungsfrequenzen gute Übertragungseigenschaften gewährleistet sind.The object of the present invention is therefore to a connection arrangement of the type mentioned create, even at very high transmission frequencies good transmission properties are guaranteed.

Diese Aufgabe wird für eine Verbindungsanordnung gemäß der vorliegenden Erfindung dadurch gelöst, daß rückwandseitig die Anschlußenden der Schirmbleche und die Anschlußenden der Kontaktdurchgänge eine Kontaktierungsschicht aus Edelmetall aufweisen, daß im Gegenbereich der Anschlußenden auf der Rückwandleiterplatte Anschlußaugen vorgesehen sind, daß sowohl die senkrecht zur Rückwandleiterplatte angeordneten Schirmbleche als auch die senkrecht zur Rückwandleiterplatte verlaufenden Kontaktdurchgänge gewellt sind, um einen Federbereich zu schaffen, dessen Hub die Kontaktkraft der gewellten Enden auf die Anschlußaugen (6) bereitstellt, und daß das Gehäuse an mehreren Stellen mechanisch auf der Rückwandleiterplatte befestigt ist.This task is for a connection arrangement according to the present invention solved in that the rear wall Connection ends of the shield plates and the connection ends of the contact passages have a contacting layer made of precious metal, that in the opposite area of the connection ends on the backplane Connection eyes are provided that both the shield plates arranged perpendicular to the backplane as well as those perpendicular to the backplane Contact passages are corrugated around a spring area to create whose stroke the contact force which provides corrugated ends on the connecting eyes (6), and that the housing mechanically in several places on the Backplane circuit board is attached.

Durch den Wegfall der eingepreßten Messer lassen sich bis in den Gigahertzbereich hinein gute Übertragungseigenschaften zwischen den Baugruppenleiterplatten und der Rückwandleiterplatte erzielen.By eliminating the pressed-in knives can be in good transmission characteristics in the gigahertz range between the assembly circuit boards and the backplane circuit board achieve.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The invention is described below with reference to a drawing illustrated embodiment explained in more detail.

Das Gehäuse 1 für die Verbindung einer Rückwandleiterplatte mit Baugruppenleiterplatten besteht im wesentlichen aus einem aus Schirmblechen bestehenden Schirmblechgefache 2 zwischen denen isoliert die einzelnen Kontaktdurchgänge angeordnet sind. Sowohl die Schirmblechgefache 2 als auch die nicht dargestellten Kontaktdurchgänge sind mit der Baugruppenleiterplatte 4 verbunden.The housing 1 for connecting a backplane with assembly circuit boards essentially consists of one shield shield compartments 2 consisting of shield plates between which isolated the individual contact passages are. Both the shield sheet compartments 2 and those not shown Contact passages are with the assembly circuit board 4 connected.

Die der Rückwandleiterplatte 5 zugewandten Anschlußenden des Schirmblechgefaches sind gewellt und weisen so einen Federbereich 3 auf. Das gleiche gilt auch für die Anschlußenden der Kontaktdurchgänge, die der Übersicht halber in der Zeichnung nicht dargestellt sind. Auch sie weisen aufgrund eines wellenförmigen Aufbaus einen Federbereich auf. Die Anschlußenden sowohl der Kontaktdurchgänge als auch die Anschlußenden, welche dem Schirmblechgefache 2 zugeordnet sind, weisen an ihrem freien Ende des Federbereichs zur Kontaktierung eine Edelmetallschicht auf. Als Gegenbereich für die Anschlußenden sind auf der Rückwandleiterplatte 5 Anschlußaugen 6 vorgesehen. Dadurch, daß die Anschlußenden sowohl der Kontaktdurchgänge als auch des Schirmblechgefaches 2 gewellt sind, wirkt mit einem bestimmten Hub eine kontinuierliche Kraft auf die Anschlußaugen 6 der Rückwandleiterplatte 5 ein.The connection ends of the backplane 5 facing the Shield panels are corrugated and thus have a spring area 3 on. The same applies to the connection ends of the Contact passages, for the sake of clarity in the drawing are not shown. They also show a wavy shape Build up a spring area. The connection ends both the contact passages and the terminal ends, which are assigned to the shielding sheet compartment 2, have on their free end of the spring area for contacting a precious metal layer on. As a counter area for the connection ends 5 connecting eyes 6 provided on the backplane. The fact that the connection ends of both the contact passages and the shielding sheet compartment 2 are corrugated, acts with a certain stroke a continuous force the connecting eyes 6 of the backplane 5.

Das Gehäuse 1 ist im eingebauten Zustand - hier nicht dargestellt - mit der Rückwandleiterplatte 5 fest verschraubt oder mittels einer anderen mechanischen Verbindung, z.B. mittels einer Schnappverbindung oder mittels einer Einpressung, verbunden, um die Kontaktkraft der Anschlußenden aufzunehmen. Da die Kontaktierung auf der Leiterplattenaußenfläche geschieht, steht einer beliebigen Leiterbahn- bzw. Gassenführung kein Einpreßloch mehr im Weg.The housing 1 is in the installed state - not shown here - screwed to the backplane 5 or by means of another mechanical connection, e.g. by means of a snap connection or by means of an injection, to absorb the contact force of the connection ends. There the contact is made on the outer surface of the circuit board, does not match any conductor track or lane routing Press-in hole more in the way.
