- Plug connections of the type mentioned at the beginning for backplane wiring, in which shielding, as indicated above, takes place in the intermediate grid, are e.g. in European patent application 94 103 192 have been proposed.
- the multilayer requires additional layers and is therefore more expensive.
- the object of the present invention is therefore to provide a backplane arrangement of the type mentioned, in which a sufficient conductor passage width is given, and which does not require expensive multilayers.
- the actual backplane wiring board consists of the backplane board 4, which can be designed as a multilayer, and a carrier board 5.

Abstract
Description
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 assembly for plug connections between backplane and assembly circuit boards, the plug connection consisting of a male connector designed as a rectangular housing that is open on one side for plugging onto the knives of a backplane and a receptacle that can be inserted into the male connector and is provided with contact springs and permanently connected to an assembly board , wherein the knives and springs are arranged in parallel in several rows, the individual contact passages being surrounded by electrically conductive shield plates, which are connected to contacts which carry shield potential in the intermediate grid both on the rear wall and on the assembly side and which have a corresponding potential applied, and wherein both the contact blades and contact springs as well as the contacts by means of press-in technology in the as more Multilayer trained printed circuit boards are contacted and attached.
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 at the beginning for backplane wiring, in which shielding, as indicated above, takes place in the intermediate grid, are e.g. in European patent application 94 103 192 have been proposed. In such connector arrangements is partly. the disadvantage exists that between the contact blades and the shield contacts arranged in the intermediate grid there is too little conductor passage width on the printed circuit boards. As a result, 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 Leiterbahndurchführungsbreite gegeben ist, und die keine teuren Multilayer benötigt.The object of the present invention is therefore to provide a backplane arrangement of the type mentioned, in which a sufficient conductor passage 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 arrangement according to the present invention in that between the backplane and the plug-in connection there is arranged a support plate which is mechanically firmly connected to the backplane, in which contact blades are pressed in or overmolded, the respective connection ends being contacted with conductor tracks of the backplane.
Bei der erfindungsgemäßen Rückwandleiterplattenanordnung ist eine ausreichende Leiterbahndurchführungsbreite zwischen den einzelnen Anschlüssen gewährleistet.In the case of the backplane circuit arrangement according to the invention, a sufficient conductor leadthrough width between the individual connections is ensured.
Zweckmäßige Ausgestaltungen der erfindungsgemäßen Rückwandleiterplattenanordnung ergeben sich aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Figur.Expedient configurations of the backplane circuit arrangement according to the invention result from the subclaims and from the following description of an exemplary 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 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 female connector 1 will not be discussed further here, since it is not essential to the invention. In this connection, reference is made to European patent application 94 103 192. Therefore, in the drawing of the female connector 1, essentially only the
Die eigentliche Rückwandverdrahtungsplatte besteht aus der Rückwandleiterplatte 4, welche als Multilayer ausgebildet sein kann, und einer Trägerplatte 5. Die Trägerplatte 5 ist zwischen der Steckverbindung, d.h. der Federleiste 1 und der Rückwandleiterplatte 4 angeordnet.The actual backplane wiring board consists of the backplane board 4, which can be designed as a multilayer, and a carrier board 5. The carrier board 5 is arranged between the plug connection, ie 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.In the carrier plate 5 contact knife 6 and shield contacts 7 are pressed or molded. The carrier plate 5 can consist of printed circuit board material or of injection-molded, heat-resistant plastic. It is attached to the backplane 4 by means of contact blades with a long, continuous press-in zone or by means of a press-in pin molded onto the carrier plate or by means of 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 contacting 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 to the corresponding connection eye or the corresponding conductor track.
