Rückwandleiterplattenanordnung für SteckverbindungenBackplane arrangement for connectors
Die vorliegende Erfindung betrifft eine Rückwandleiterplattenanordnung für Steckverbindungen zwischen Rückwandleiterplatten und Baugruppenleiterplatten, wobei die Steckverbindung aus einer als einseitig offenes rechtwinkliges Gehäuse ausgebildeten Messerleiste zum Aufstecken auf die Messer einer Rückwandleiterplatte und einer in die Messerleiste einsteckbaren mit Kontaktfedern bestückten Aufnahmekammern versehenen und mit einer Baugruppenleiterplatte fest verbundenen Federleiste, wobei die Messer und Federn parallel in mehreren Reihen angeordnet sind, besteht, wobei die einzelnen Kontaktdurchgänge von elektrisch leitfähigen Schirmblechen umgeben sind, welche mit im Zwischenraster sowohl rückwandseitig als auch baugruppenseitig angebrachten Schirmpotential führenden Kontaktierungen verbunden sind, die mit einem entsprechenden Potential beaufschlagt sind, und wobei sowohl die Kontaktmesser und Kontaktfedern als auch die Kontaktierungen mittels Einpreßtechnik in die als mehrlagige Multilayer ausgebildeten Leiterplatten kontaktiert und befestigt sind.The present invention relates to a backplane circuit board arrangement for plug connections between backplane circuit boards and assembly circuit boards, whereby the plug connection consists of a male connector designed as a rectangular housing open on one side for plugging onto the blades of a backplane circuit board and a spring connector that can be plugged into the male connector and is provided with contact springs and is firmly connected to an assembly circuit board, whereby the blades and springs are arranged in parallel in several rows, whereby the individual contact passages are surrounded by electrically conductive shielding plates, which are connected to shielding potential-carrying contacts arranged in the intermediate grid on both the backplane side and the assembly side, which are charged with a corresponding potential, and whereby both the contact blades and contact springs as well as the contacts are contacted and fastened by means of press-fitting technology in the circuit boards designed as multilayers.
Steckverbindungen der eingangs genannten Art für Rückwandverdrahtungen, bei welchen eine Schirmung, wie oben angegeben, im Zwischenraster erfolgt, sind z.B. in der europäischen Patentanmeldung 94 103 192 vorgeschlagen worden. Bei derartigen Steckverbinderanordnungen ist z.T. der Nachteil vorhanden, daß zwischen den Kontaktmessern und den im Zwischenraster angeordneten Schirmkontaktierungen eine zu geringe Leiterbahndurchführungsbreite auf den Leiterplatten gegeben ist. Dies hat zur Folge, daß der Multilayer zusätzliche Lagen benötigt und damit teurer wird.Plug connections of the type mentioned above for rear panel wiring, in which shielding, as stated above, takes place in the intermediate grid, have been proposed, for example, in European patent application 94 103 192. Such plug connector arrangements sometimes have the disadvantage that the conductor path feedthrough width on the circuit boards between the contact blades and the shield contacts arranged in the intermediate grid is too small. This means that the multilayer requires additional layers and is therefore more expensive.
Die Aufgabe der vorliegenden Erfindung besteht daher darin, eine Rückwandleiterplattenanordnung der eingangs genannten Art zu schaffen, bei der eine ausreichende Leiterbahndurch-The object of the present invention is therefore to create a backplane circuit board arrangement of the type mentioned at the beginning, in which a sufficient conductor path through

führungsbreite gegeben ist, und die keine teuren Multilayer benötigt.guide width is given and which does not require expensive multilayers.
Diese Aufgabe wird für die obengenannte Rückwandleiterplattenanordnung gemäß der vorliegenden Erfindung dadurch gelöst, daß zwischen Rückwandleiterplatte und Steckverbindung eine mit der Rückwandleiterplatte mechanisch fest verbundene Trägerplatte angeordnet ist, in welcher Kontaktmesser eingepreßt oder umspritzt gehalten sind, wobei die jeweiligen Anschlußenden mit Leiterbahnen der Rückwandleiterplatte kontaktiert sind.This object is achieved for the above-mentioned backplane circuit board arrangement according to the present invention in that a support plate which is mechanically firmly connected to the backplane circuit board is arranged between the backplane circuit board and the plug connection, in which support plate contact blades are pressed in or molded over, the respective connection ends being contacted with conductor tracks of the backplane circuit board.
Bei der erfindungsgemäßen Rückwandleiterplattenanordnung ist eine ausreichende Leiterbahndurchführungsbreite zwischen den einzelnen Anschlüssen gewährleistet.The backplane circuit board arrangement according to the invention ensures a sufficient conductor track feedthrough width between the individual connections.
Zweckmäßige Ausgestaltungen der erfindungsgemäßen Rückwandleiterplattenanordnung ergeben sich aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Figur.Appropriate embodiments of the backplane circuit board arrangement according to the invention are evident from the subclaims and from the following description of an embodiment with reference to the figure.
Auf den eigentlichen Aufbau der Federleiste 1 soll hier nicht weiter eingegangen werden, da dieser nicht erfindungswesentlich ist. Es wird in diesem Zusammenhang auf die europäische Patentanmeldung 94 103 192 verwiesen. Daher sind in der Zeichnung von der Federleiste 1 im wesentlichen nur das Schirmblechgefache 2 z.T. detailliert dargestellt. Baugruppenseitig ist die Federleiste mit einer Baugruppenleiterplatte 3 fest verbunden. Auf diese Art der Verbindung soll hier 0 ebenfalls nicht eingegangen werden, da diese nicht erfindungswesentlich ist. Außerdem kann diese Verbindung zwischen Federleiste 1 und Baugruppenleiterplatte 3 auf unterschiedliche Art und Weise erfolgen.The actual structure of the spring strip 1 will not be discussed here, as it is not essential to the invention. In this context, reference is made to European patent application 94 103 192. Therefore, in the drawing of the spring strip 1, essentially only the shielding plate compartment 2 is shown in some detail. On the assembly side, the spring strip is firmly connected to an assembly circuit board 3. This type of connection will not be discussed here either, as it is not essential to the invention. In addition, this connection between the spring strip 1 and the assembly circuit board 3 can be made in different ways.
Die eigentliche Rückwandverdrahtungsplatte besteht aus der Rückwandleiterplatte 4, welche als Multilayer ausgebildet sein kann, und einer Trägerplatte 5. Die Trägerplatte 5 istThe actual backplane wiring board consists of the backplane circuit board 4, which can be designed as a multilayer, and a carrier plate 5. The carrier plate 5 is

zwischen der Steckverbindung, d.h. der Federleiste 1 und der Rückwandleiterplatte 4 angeordnet.between the plug connection, i.e. the female connector 1 and the backplane 4.
In die Trägerplatte 5 werden Kontaktmesser 6 und Schirmkontaktierungen 7 eingepreßt oder umspritzt gehalten. Die Trägerplatte 5 kann aus Leiterplattenmaterial oder aus gespritztem, wärmebeständigem Kunststoff bestehen. Sie wird mittels Kontaktmessern mit langer, durchgehender Einpreßzone oder mittels an der Trägerplatte angespritztem Einpreßzapfen oder mittels einer Schraubverbindung auf der Rückwandleiterplatte 4 angebracht.Contact blades 6 and shield contacts 7 are pressed or molded into the carrier plate 5. The carrier plate 5 can be made of circuit board material or of molded, heat-resistant plastic. It is attached to the backplane circuit board 4 using contact blades with a long, continuous press-in zone or using a press-in pin molded onto the carrier plate or using a screw connection.
Um die Kontaktierung auf dem Multilayer sicherzustellen, stehen die Anschlußenden der Kontaktmesser 6 und der Schirmkontaktierungen 7 geringfügig über die Trägerplatte 5 hinaus, bzw. besitzen eine elastische leitende Einlage 8, z.B. verzinkte Kontaktwolle. Dadurch ist eine sichere Verbindung mit dem entsprechenden Anschlußauge bzw. der entsprechenden Leiterbahn gewährleistet.In order to ensure contact on the multilayer, the connection ends of the contact blades 6 and the shield contacts 7 protrude slightly beyond the carrier plate 5 or have an elastic conductive insert 8, e.g. galvanized contact wool. This ensures a secure connection with the corresponding connection eye or the corresponding conductor track.
