Steckverbindung für LeiterplattenConnector for printed circuit boards
Elektronische Geräte oder Systeme bestehen in der Regel aus einer Vielzahl von Baugruppen, die auf individuellen Leiterplatten angeordnet werden, wobei die Leiterplatten über Steckverbinder und ein gemeinsames Leitungssystem miteinander verbunden sind, um Signale untereinander austauschen zu können. Dieses Leitungssystem kann auch als sogenanntes BUS-System ausgebildet sein, wenn die einzelnen Baugruppen selbständige Funktionseinheiten bilden, z.B. die Prozessoren, die Speicher und die Ein-/Ausgabeeinheiten einer Datenverarbeitungsanlage. Die Baugruppen können dabei auch aus integrierten Schaltkreismodulen bestehen.Electronic devices or systems usually consist of a large number of components that are arranged on individual circuit boards, whereby the circuit boards are connected to one another via connectors and a common cable system in order to be able to exchange signals with one another. This cable system can also be designed as a so-called BUS system if the individual components form independent functional units, e.g. the processors, the memories and the input/output units of a data processing system. The components can also consist of integrated circuit modules.
Bei der üblichen Konstruktion/ wonach die Baugruppen als Einschübe in einem Rahmen an vorgegebenen Einbauplätzen parallel zueinander angeordnet sind und das Leitungssystem als Rück-0 wandverdrahtung ausgebildet ist, ergeben sich zwangsläufig unterschiedlich lange Signalwege zwischen den Steckeranschlüssen verschiedener Baugruppen oder Einschübe, was zu unterschiedlichen Laufzeiten der Signale und zu Signalverzerrungen führt. Dies wirkt sich um so nachteiliger auf die Zusammenarbeit der Baugruppen aus, je höher die Arbeitsfrequenz und die Übertragungsgeschwindigkeit ist.In the usual design, whereby the modules are arranged parallel to one another as inserts in a frame at specified installation locations and the cable system is designed as backplane wiring, signal paths of different lengths inevitably arise between the plug connections of different modules or inserts, which leads to different signal propagation times and signal distortions. This has a more detrimental effect on the cooperation of the modules the higher the operating frequency and the transmission speed.
Aufgabe der Erfindung ist es daher, die aufgezeigten Nachteile der bekannten Konstruktion zu vermeiden. Dies wird durch eine Steckerverbindung gemäß den Merkmalen des Anspruchs 1 erreicht.The object of the invention is therefore to avoid the disadvantages of the known construction. This is achieved by a plug connection according to the features of claim 1.
Danach sind die einzelnen Leiterplatten nicht mehr parallel zueinander ausgerichtet, sondern auf dem Steckverbinder sind auf einem Kreisbogen um eine gemeinsame Achse mit gleichem Abstand von der Achse angeordnet, und die einander entsprechenden Anschlüsse der Steckverbinder sind über in der AchseAfter that, the individual circuit boards are no longer aligned parallel to each other, but are arranged on the connector on an arc around a common axis at the same distance from the axis, and the corresponding connections of the connectors are connected via

angeordnete Signalknoten miteinander verbunden. Der Signalweg zwischen den Anschlüssen zweier beliebiger Steckverbinder ist daher für alle möglichen Verbindungen gleich lang. Auch bestehen für alle Verbindungen, die gleichen elektrischen Verhältnisse. arranged signal nodes are connected to each other. The signal path between the connections of any two connectors is therefore the same length for all possible connections. The same electrical conditions also apply for all connections.
Zweckmäßig erfolgt auch die Stromversorgung und die Bereitstellung von Bezugspotentialen und Arbeitstakten in analoger Weise über in der Achse angeordnete Signalknoten.It is also practical to supply power and provide reference potentials and operating cycles in an analog manner via signal nodes arranged in the axis.
Besondere Vorteile ergeben sich, wenn die aus den einzelnen Signalknoten gebildete Achse in einem metallischen Gehäuse angeordnet ist, dessen Seitenwand als Träger für Teile, z.B. die Buchsenleisten, der Steckverbinder dient. Das Gehäuse in Form einer Säule ist damit Träger für die Steckverbinder mit den Leiterplatten und gleichzeitig auch Abschirmung für das innenliegende Leitungssystem, was bessere EMV-Eigenschaften mit sich bringt.Particular advantages arise when the axis formed by the individual signal nodes is arranged in a metal housing, the side wall of which serves as a carrier for parts, e.g. the socket strips, the connectors. The housing in the form of a column is thus a carrier for the connectors with the circuit boards and at the same time also a shield for the internal cable system, which brings with it better EMC properties.

' Abhängig von der Lage der einzelnen Leiterplatten im Rahmen sind die Signalwege zwischen den Steckverbindern SV zweier Leiterplatten LP der Anordnung unterschiedlich lang.' Depending on the position of the individual circuit boards in the frame, the signal paths between the connectors SV of two circuit boards LP in the arrangement are of different lengths.
Ordnet man dagegen gemäß FIG 2 die Steckverbinder SV auf einen Kreisbogen mit dem Radius R liegend um eine gemeinsame Achse an, in der auch die Signalknoten SK für die Verbindung der einander entsprechenden Anschlüsse aller Steckverbinder SV liegen, dann sind die Signalwege für alle möglichen Ver-.bindungen zwischen den einzelnen Steckverbindern SV gleich lang, nämlich gleich dem doppelten Radius R. Die Steckverbinder können dabei gleichmäßig auf dem gesamten Umfang des Kreisbogens verteilt sein. Raumsparender ist dagegen eine Verteilung auf einem Halbkreisbogen, wie in FIG 2 gezeigt, 0 oder nur auf dem Bogenabschnitt eines Sektors, was aber von der Anzahl der miteinander zu verbindenden Leiterplatten und deren Aufbauhöhe abhängig ist.If, however, the connectors SV are arranged on a circular arc with radius R around a common axis as shown in FIG 2, in which the signal nodes SK for connecting the corresponding connections of all connectors SV are also located, then the signal paths for all possible connections between the individual connectors SV are the same length, namely twice the radius R. The connectors can be evenly distributed over the entire circumference of the circular arc. On the other hand, a distribution on a semicircular arc, as shown in FIG 2, 0 or only on the arc section of a sector is more space-saving, although this depends on the number of circuit boards to be connected and their installation height.
Als Halterung für die einzelnen Buchsenleisten BL der Steckverbinder dient gemäß FIG 3 zweckmäßig ein geschlossenes metallisches Gehäuse, z.B. aus einem weichmagnetischen Werkstoff, in dessem Innern die aus den Signalknoten SK bestehende Achse angeordnet ist und in dessen Seitenwand die Buchsenleisten BL eingesetzt sind. Dieses Gehäuse wirkt dann 0 gleichzeitig als Abschirmung für das Leitungssystem und verbessert so die EMV-Eigenschaften.As shown in FIG 3, a closed metal housing, e.g. made of a soft magnetic material, serves as a holder for the individual socket strips BL of the connectors. The axis consisting of the signal nodes SK is arranged inside the housing and the socket strips BL are inserted into the side wall. This housing then simultaneously acts as a shield for the cable system and thus improves the EMC properties.
FIG 4 zeigt schließlich eine von dem metallischen Gehäuse MG gebildete Steckverbindersäule mit einem sechseckförmigen Grundriß für insgesamt sechs am Umfang verteilte Leiterplatten LP, von denen nur eine dargestellt ist.
