Abstract
Description
Die Erfindung betrifft einen Steckverbinder für Leiterplatten, insbesondere der Datentechnik mit einer mehrlagigen flexiblen Leiterplatte in Form einer Folie, die abwechselnd Ebenen für Signalleiter und Potentialleiter aufweist, die für einen jeweils zu erzielenden bestimmten Wellenwiderstandswert in einer festen geometrischen Konfiguration zueinander stehen, und bei der die Leiterbahnen der einzelnen Ebenen am anderen Ende der flexiblen Folie freigelegt sind.The invention relates to a connector for printed circuit boards, in particular data technology with a multi-layer flexible printed circuit board in the form of a film, which alternately has levels for signal conductors and potential conductors, which stand for each other in a fixed geometric configuration for a specific wave resistance value to be achieved, and in which the Conductor tracks of the individual levels are exposed at the other end of the flexible film.
Datenverarbeitungsanlagen werden mit immer höheren Taktfrequenzen betrieben. Dadurch werden Signallaufzeiten, Übersprechen, Induktivitäten, Kapazitäten und Reflexionen an elektromechanischen Schnittstellen, wie Steckverbindern immer kritischer. Die bisher eingesetzten Steckverbinder stellen die Verbindung zur Leiterplatte mit Anschlußbeinchen her und haben daher lange Signalwege und hohen Platzbedarf. Die meisten Steckverbinder weisen für hohe Taktfrequenzen ungeeignete Kennwert auf, da sie gewisse elektrische Eigenschaften, wie kontrollierten Wellenwiderstand, in den geforderten Werten nicht erfüllen können.Data processing systems are operated at ever higher clock frequencies. As a result, signal propagation times, crosstalk, inductances, capacitances and reflections at electromechanical interfaces, such as connectors, are becoming increasingly critical. The connectors used up to now establish the connection to the printed circuit board with connecting legs and therefore have long signal paths and a large amount of space. Most connectors have an unsuitable characteristic value for high clock frequencies because they cannot fulfill certain electrical properties, such as controlled characteristic impedance, in the required values.
In der US-PS 4,755,147 wird bereits ein Stecker beschrieben, bei dem zur Verbindung der Steckerstifte mit einer gedruckten Leiterplatte eine zweilagige flexible Leiterplatte verwendet wird, wobei sich in der einen Lage die Signalleitungen befinden und in der anderen Lage das Massepotential zugeführt wird. Diese flexible Leiterplatte ist an ihrem einen Ende freigelegt und die freien Leiterbahnen sind mit den jeweiligen Lötflecken auf der zugehörigen Leiterplatte verlötet. Mit dieser Leiterplatte soll ebenfalls eine Fehlanpassung zwischen Stecker und gedruck ter Leiterplatte vermieden werden.US Pat. No. 4,755,147 already describes a plug in which a two-layer flexible printed circuit board is used to connect the plug pins to a printed circuit board, the signal lines being in one layer and the ground potential being supplied in the other layer. This flexible circuit board is exposed at one end and the free conductor tracks are soldered to the respective solder spots on the associated circuit board. With this circuit board a mismatch between the connector and printed ter circuit board should also be avoided.
Aus der europäischen Patentanmeldung 0 145 083 A3 ist ebenfalls ein elektrischer Stecker bekannt, mit dessen Hilfe zwei mit Leiterbahnen versehene, senkrecht aufeinanderstehende Leiterplatten miteinander verbunden werden sollen, wobei der Stecker in seinem Inneren zwei gegenüberliegende, dachförmig gebogene, aus flexiblen Leiterplatten bestehende Prismen aufweist, auf deren Oberflächen Leiterbahnen angeordnet sind, die die Verbindung zwischen den Leiterbahnen der waagrechten und den Leiterbahnen der senkrechten Platte durch Einstecken der senkrechten Platte in den Zwischenraum zwischen den beiden Prismenteilen herstellen. Auch dieser Entgegenhaltung ist zu entnehmen, daß durch Zweilagigkeit von Signal- und Massepotentiallagen eine Fehlanpassung zwischen den Leitern der beiden Leiterplatten vermieden werden soll. Außerdem soll dadurch die Signallaufzeit verringert werden.From European patent application 0 145 083 A3 an electrical connector is also known, with the aid of which two printed circuit boards, which are arranged perpendicular to one another and are to be connected, are to be connected to one another, the inside of the connector having two opposite, roof-shaped, prisms consisting of flexible printed circuit boards, on the surfaces of which there are arranged conductor tracks which produce the connection between the conductor tracks of the horizontal plate and the conductor tracks of the vertical plate by inserting the vertical plate into the space between the two prism parts. It can also be gathered from this document that a mismatch between the conductors of the two printed circuit boards is to be avoided by two-layer signal and ground potential layers. It is also intended to reduce the signal propagation time.
Aufgabe der vorliegende Erfindung ist es, einen Steckverbinder für Leiterplatten mit definierten elektrichen Eigenschaften, wie Impedanz, Übersprechen und Wellenwiderstand zu schaffen.The object of the present invention is to create a connector for printed circuit boards with defined electrical properties, such as impedance, crosstalk and wave resistance.
Zur Lösung dieser Aufgabe wird der Steckverbinder gemäß der Erfindung derart ausgebildet, daß am einen Ende zwei aufeinanderliegende Versteifungsplatten auflaminiert sind, von denen die erste durchkontaktierte Bohrungen enthält, in die die Stifte oder Lötfahnen eingelötet sind, und die zweite mit Aussparungen zur Aufnahme von Lötzinn an den Stellen, an denen sich die Bohrungen der ersten Leiterplatte befinden, versehen ist.To achieve this object, the connector according to the invention is designed in such a way that two superimposed stiffening plates are laminated on one end, the first of which contains plated-through holes into which the pins or soldering tags are soldered, and the second with cutouts for receiving solder the locations where the holes of the first circuit board are provided.
Durch diese Maßnahmen wird ein in seinen elektrischen Werten definierter Steckverbinder erhalten, wobei je nach geometrischer Konfiguration sich die Wellenwiderstände ändern.These measures result in a connector defined in its electrical values, the wave resistances changing depending on the geometric configuration.
Vorteilhaft ist es auch am anderen Ende der flexiblen Folie einen Versteifungsbügel aufzulaminieren, der im Bereich der freigelegten Enden der Leiterbahnen eine Aussparung besitzt.It is also advantageous to laminate a stiffening bracket on the other end of the flexible film, which has a recess in the area of the exposed ends of the conductor tracks.
Ein Ausführungsbeispiel zur Erzielung eines definierten Wellenwiderstandes sieht vor, daß die Leiter in den Signalebenen parallel und in Längsrichtung zur flexiblen Leiterfolie verlaufen, daß die Leiter in den Potentialebenen als Gitterwerk ausgebildet sind und die längs zur Folie verlaufenden Leiterbahnen so angeordnet sind, daß sie unter oder überhalb der Zwischenräume der Leiter der Signalebenen verlaufen.An embodiment to achieve a defined characteristic impedance provides that the conductors in the signal planes run parallel and in the longitudinal direction to the flexible conductor film, that the conductors in the potential planes are designed as a lattice work and that the conductor tracks running longitudinally to the film are arranged such that they are under or run above the spaces between the conductors of the signal planes.
Ein anderes Ausführungsbeispiel ergibt sich dadurch, daß die Leiter für die Signal- und die Potentialübertragung in einer Ebene und zwar abwechselnd nebeneinander angeordnet sind.Another embodiment results from the fact that the conductors for signal and potential transmission are arranged in one plane, alternately next to one another.
Wieder andere Werte des Wellenwiderstandes werden erhalten, wenn man die flexible Leiterfolie derart ausbildet, daß die Potentialleiter aus einer flächigen Metallage bestehen.Still other values of the wave resistance are obtained if the flexible conductor foil is formed in such a way that the potential conductors consist of a flat metal layer.
Weiterhin kann der Steckverbinder auch so ausgebildet sein, daß sich die Signalleiterebene mit ihren Einzelleiterbahnen zwischen zwei flächenhaft ausgebildeten Potentialleiterebenen befindet.Furthermore, the connector can also be designed such that the signal conductor level with its individual conductor paths is located between two planar potential conductor levels.
Die Leiter der Signallage und die Längsleiter der Potentiallage in den einzelnen Ebenen können auch deckungsgleich untereinanderliegen. Eine weitere Möglichkeit besteht darin, daß der Rasterabstand der Potentialleiter größer ist als der Rasterabstand der Signalleiter.The conductors of the signal position and the longitudinal conductors of the potential position in the individual levels can also be congruent with one another. Another possibility is that the grid spacing of the potential conductors is greater than the grid spacing of the signal conductors.
Zur Schirmung ist es vorteilhaft, eine Lage seitlich und nach vorn über die flexible Folie 1 herausragen zu lassen und diese als Metallfläche auszubilden.For shielding, it is advantageous to have a layer protrude laterally and forward over the
Anhand der Ausführungsbeispiele nach den FIG 1 bis 10 wird die Erfindung näher erläutert.The invention is explained in more detail using the exemplary embodiments according to FIGS. 1 to 10.

Die Stifte 2 sind in den auflaminierten Versteifungsleisten 8 bzw. 9 gehalten. Das Steckerteil selbst ist in einem als Schutzkragen 3 ausgebildeten Gehäuse über eine Traverse 30 gehalten.

Eine andere Konfiguration zeigt FIG 8, bei der zwischen zwei flächig ausgebildeten Potentialebenen die Signalleiter in einer eigenen Ebene angeordnet sind.Different possibilities of the geometrical arrangement of signal and potential conductors are shown in the following figures.

Je nach Ausbildung erhält man einen anderen Wellenwiderstand, so daß dadurch praktisch jeder gewünschte Wellenwiderstand herstellbar ist.
