Description
Die Erfindung betrifft ein Leiterplatten-Verbinderelement mit einer Vielzahl von gitterförmig in Spalten und Reihen in einer Federleiste aus Isolierstoff angeordneten Signalkontakten, und mit einer Abschirmeinheit, die ein erstes und zweites Masseplättchen enthält, die leitend sind, die auf gegenüberliegenden Seiten mindestens eines der Signalkontakte angeordnet sind und die über eine Brücke leitend miteinander verbunden sind, wobei die Abschirmeinheit einen von ihr abstehenden ersten Masseanschluß aufweist, der mit der Leiterplatte leitend verbindbar ist.The invention relates to a circuit board connector element a variety of grid-like in columns and rows in one Female connector made of insulating contacts arranged signal contacts, and with a shielding unit having first and second Contains platelets that are conductive on opposite ones Sides of at least one of the signal contacts arranged and they are conductive to each other over a bridge are connected, the shielding unit projecting from it has the first ground connection with the printed circuit board is conductively connectable.
Ein derartiges Leiterplatten-Verbinderelement ist aus der DE 44 10 047 A1 bekannt.Such a circuit board connector element is from DE 44 10 047 A1 known.
Ein weiteres Verbinderelement ist aus US-A-4 898 546 bekannt.Another connector element is out US-A-4,898,546 is known.
Niederfrequenz-Leiterplattensteckverbinder werden in zunehmendem Maße mit schnelleren digitalen Signalen betrieben. Die sehr steilen Signalanstiegsflanken korrespondieren mit hohen Frequenzen. Dadurch entstehen Probleme mit der Signalübertragungsqualität, insbesondere entstehen zwischen benachbarten Signalkontakten unerwünschte Nebensprecheffekte. Andererseits ist absehbar, daß in zukünftigen Geräten sowohl Baugruppen mit sehr schnellen Signalen, als auch solche mit weniger schnellen Signalen eingesetzt werden. Von daher entsteht das Bedürfnis, sowohl frequenzoptimierte Federleisten als auch Standardfederleisten durch Stecken mit Standardmesserleisten auf der Geräterückwand zu verbinden und zu betreiben.Low frequency circuit board connectors are becoming increasingly popular Dimensions operated with faster digital signals. The very steep signal rising edges correspond to high Frequencies. This creates problems with the signal transmission quality, in particular arise between neighboring ones Signal contacts unwanted crosstalk effects. on the other hand it is foreseeable that in future devices both assemblies with very fast signals, as well as those with less fast signals are used. So that's where it comes from Need both frequency-optimized female connectors as well Standard female connectors by plugging in with standard male connectors to connect and operate on the rear panel.
Konventionell kann das Problem des Nebensprechens dadurch gelöst werden, daß die Signale nur über jeden zweiten Kontakt geführt werden, während die dazwischenliegenden Kontakte mit Masse belegt werden. Bei dieser Lösung ist jedoch die Anzahl der für die Signalübertragung nutzbaren Anschlüsse drastisch verringert, so daß sie für Anwendungen mit einer hohen Signaldichte wenig brauchbar erscheint.Conventionally, this can solve the crosstalk problem be that the signals only through every second contact out, while the intermediate contacts with Mass to be occupied. With this solution, however, the number is of the connections usable for signal transmission drastically reduced, making them suitable for applications with a high signal density appears to be of little use.
Aus der DE 40 40 551 C2 ist es bekannt, ein Übersprechen zwischen einander benachbarten Anschlüssen in einander benachbarten vertikalen Reihen durch Einfügen eines Abschirmelementes zwischen die vertikalen Anschlußreihen einer Federleiste zu verhindern. Nachteilig bei dieser Lösung ist jedoch, daß von den fünf verfügbaren Kontaktreihen nur drei Reihen für Signale brauchbar sind, und zwei Reihen mit Masse belegt werden.From DE 40 40 551 C2 it is known to cross-talk between adjacent connectors in adjacent connectors vertical rows by inserting a shielding element between the vertical connection rows of a female connector to prevent. A disadvantage of this solution, however, is that out of the five available contact rows, only three rows for Signals are usable, and two rows are grounded become.
Aus der eingangs genannten Offenlegungsschrift ist zwar eine Abschirmeinheit mit zwei durch eine Brücke verbundenen Schottblechen bekannt. Es werden dort jedoch ausschließlich Verbinderelemente vorgeschlagen, vgl. die Figuren 2, 7 und 8, bei denen jeweils nur eine erste, vordere Hälfte der Signalkontakte einer Spalte unmittelbar durch die zu dieser Spalte gehörige Abschirmeinheit geschirmt ist. Die andere Hälfte der Spalte ist durch zwei weitere Abschirmeinheiten geschirmt, die an den links und rechts benachbarten Spalten angeordnet sind und sich dort jeweils nur entlang der zweiten, hinteren Hälfte der Signalkontakte erstrecken. Diese bekannte konstruktive Lösung hat den Nachteil, daß in jeder Spalte jeweils ein Signalkontakt mit Masse belegt werden muß, da für jede Spalte eine Abschirmeinheit vorgesehen ist, was an sich schon fertigungstechnisch aufwendig ist. Unvorteilhaft hinsichtlich der Herstellung ist außerdem die Tatsache, daß zwei unterschiedliche Abschirmeinheiten Verwendung finden, sowie die sich insgesamt ergebende komplizierte Montagefolge. Von der Arbeitsweise der Abschirmung her ist die bekannte Lösung insofern problematisch, als dort jede Abschirmeinheit nur mit einem Masseanschluß mit der Leiterplatte verbindbar ist, wodurch der Rückflußstrom nicht den idealen Weg verfolgen kann.One is from the above-mentioned laid-open publication Shielding unit with two connected by a bridge Schott plates known. However, it will only be there Connector elements proposed, cf. Figures 2, 7 and 8, where only a first, front half of the signal contacts a column directly through to that column appropriate shielding unit is shielded. The other half of the Column is shielded by two further shielding units, the arranged on the left and right adjacent columns and there are only along the second, rear one Half of the signal contacts extend. This well-known constructive Solution has the disadvantage that in each column a signal contact must be connected to ground, because for a shielding unit is provided for each column, which in itself is already complex to manufacture. Disadvantageous in terms of the manufacture is also the fact that two different shielding units are used, as well the overall complex assembly sequence that results. Of the way the shielding works is the known solution problematic in that each shielding unit there only with a ground connection can be connected to the circuit board, whereby the return flow cannot follow the ideal path.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen verbesserten Steckverbinder der eingangs genannten Art zu schaffen, der insbesondere Nebensprechen zuverlässig verhindert, der konstruktive Änderungen nur bei einem Verbinderelement, der Federleiste, bedingt und der einfach herstellbar ist.The present invention is based on the object improved connectors of the type mentioned create that reliably prevents crosstalk in particular, the design changes only for one connector element, the female connector, conditional and easy to manufacture is.
Diese Aufgabe wird bei einem Verbinderelement der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß die Abschitmeinheit einen Federkontakt enthält der die Stelle des mittleren Signalkontakts der jeweiligen Spalte einnimmt.This task is the beginning of a connector element mentioned type solved according to the invention, that the cutting unit contains a spring contact the position of the middle signal contact of the respective Column occupies.

In Figur 1 oben ist eine erfindungsgemäße Abschirmeinheit 3
dargestellt, die zwei parallele Masseplättchen 4 und 5 aufweist,
die am messerleistenseitigen Ende der Abschirmeinheit,
in Figur 1 also ganz oben, über eine Brücke 6, die einen von
ihr abstehenden einpreßbaren ersten Masseanschluß 7 aufweist,
leitend miteinander verbunden sind. Am messerleistenseitigen
Ende der Abschirmeinheit 3 ist ein am Masseplättchen 4 ausgebildeter
Schneidklemmkontakt 9 angedeutet. Der gegenüberliegend
am Masseplättchen 5 ebenso ausgebildete Schneidklemmkontakt
10 ist aufgrund der gewählten Perspektive nicht erkennbar.1 shows a
Die vorliegende Erfindung bekämpft das Nebensprechen grundsätzlich mittels Masseplättchen, die zwischen den Signalkontakten einer Spalte in der Federleiste angebracht werden. Diese Masseplättchen müssen einen niederohmigen Kontakt mit einem oder mehreren Stiftkontakten auf der Geräterückwand bzw. der Messerleiste machen. Dieser Kontakt muß soweit wie möglich vorne in der Federleiste stattfinden, damit die induzierten Ströme auf kürzesten Wegen neutralisiert werden können. Die als Masseplättchen ausgebildeten Schirmbleche reduzieren induktives und kapazitives Übersprechen und wirken als induktivitätsarme Verbindungswege zur Masse, um die Signalwegimpedanz zu mindern. Sie verbessern die Übertragungsqualität des Signals.The present invention basically combats crosstalk by means of ground plates between the signal contacts a column in the female connector. These ground plates must have a low-resistance contact with one or more pin contacts on the back of the device or the knife bar. This contact must go as far as possible to take place in the front of the female connector so that the induced Currents can be neutralized in the shortest possible way. Reduce the shield plates designed as ground plates inductive and capacitive crosstalk and act as Low inductance connection paths to the earth to the Reduce signal path impedance. They improve the transmission quality of the signal.
Zur Herstellung eines Massekontakts von der Messerleiste über
die Federleiste bzw. die Abschirmeinheit bis zur mit der Federleiste
verbundenen Leiterplatte ist erfindungsgemäß in der
Abschirmeinheit 3 ein Federkontakt 8 vorgesehen, der die
Stelle eines Signalkontakts 2 der jeweiligen Spalte einnimmt.
Dieser Federkontakt 8 kann vorteilhaft von gegenüberliegend
an den messerleistenseitigen Enden der Masseplättchen 4, 5
jeweils ausgebildeten Schneidklemmkontakten 9 und 10 gehalten
sein, wie in den Figuren 1 und 2 an verschiedenen Ausführungsformen
dargestellt.To make a ground contact from the male connector via
the female connector or the shielding unit up to the female connector
connected circuit board is according to the invention in the
Bei der Ausführung gemäß Figur 1 ist der Federkontakt 8 mit
seitlichen, in Längsrichtung der Federleiste 1 liegenden
Schultern 11 ausgebildet, die somit auf einfache Weise einen
Halt durch die Schneidklemmkontakte 9 und 10 und damit eine
sichere elektrische Verbindung ermöglichen. Die Ausführungsform
gemäß Figur 2 unterscheidet sich davon dadurch, daß dort
am messerleistenseitigen Ende eines Kontaktschenkels des Federkontakts
8 eine breite, in Längsrichtung der Federleiste
liegende Fahne 12 ausgebildet ist, die an den Seiten jeweils
wiederum durch einen Schneidklemmkontakt 9 und 10 gehalten
ist. Die Montage erfolgt bei der Ausführung nach Figur 1 derart,
daß zunächst der Federkontakt 8 im Isolierkörper der Federleiste
1 eingesetzt wird und daß anschließend die messerleistenseitig
als Signalfederkontakte ausgebildeten Signalkontakte
2 eingesetzt werden. Jeweils zwei Masseplättchen
werden dann zusammenhängend als Bügel gebogen, und gleichzeitig
zwischen den Signalfederkontakten eingesetzt, wobei die
Masse-Kontaktierung an den Schneidklemmkontakten 9 und 10 erfolgt.
Bei der Montage der Abschirmeinheit 3 gemäß Figur 2
werden zuerst die Signalfederkontakte im Isolierkörper der
Federleiste bestückt, anschließend werden die Masseplättchen
dazwischengeschoben, und mittels der Schneidklemmkontakte 9
und 10 an der Fahne 12 des Federkontakts 8 kontaktiert.In the embodiment according to Figure 1, the spring contact 8 is with
lateral, lying in the longitudinal direction of the female connector 1
Für praktische Anwendungen ist es vorteilhaft, wenn, wie bei
den Ausführungen gemäß Figur 1 und 2, der mittlere Signalkontakt
2 der jeweiligen Spalte durch den Federkontakt 8 und
durch den Masseanschluß 7 ersetzt ist. Die Abschirmeinheit 3
mit dem für den Massenanschluß zur Messerleiste hin vorgesehenen
Federkontakt 8 wird, wie aus Figur 1 entnehmbar, in jede
zweite Spalte der Federleiste 1 eingesetzt. Für die Federkontakte
8 ist in den betreffenden Spalten der Federleiste 1
dabei jeweils eine Öffnung 16 vorgesehen. Erfindungsgemäß gelingt
die vollständige spaltenweise Schirmung der Signalkontakte
demnach mittels einheitlich ausgebildeter Abschirmeinheiten
3, wobei es besonders vorteilhaft ist, daß pro zwei
Spalten nur eine Abschirmeinheit benötigt wird. Dies bringt
den weiteren Vorteil mit sich, daß pro zwei Spalten nur ein
Signalkontakt mit Masse belegt werden muß.
Es ist elektrisch günstiger, wenn an der Abschirmeinheit 3,
wie in den Figuren 1 und 2 dargestellt, mindestens ein zweiter
einpreßbarer Masseanschluß 13 ausgebildet ist. In vieler
Hinsicht als optimal hat sich die in Figur 1 und 2 dargestellte
Konfiguration herausgestellt, bei der die Brücke 6 an
dem dem messerleistenseitigen Ende der Abschirmeinheit 3 gegenüberliegenden
Ende angeordnet ist und bei der die Einpreßanschlüsse
der jeweiligen Signalkontaktspalte sich spaltenartig
zwischen dem hinter diesen Einpreßanschlüssen liegenden
ersten Masseanschluß 7 und dem vor diesen Einpreßanschlüssen
liegenden weiteren Masseanschlüssen 13 erstrecken. Dies geht
genauer aus den in den Figuren 3 und 4 gezeigten Konfigurationen
der Anschlußbohrungen auf der Leiterplatte hervor. Die
Anschlüsse sind insgesamt so verlegt bzw. ausgeformt, daß eine
optimale Führung des Rückflußstromes möglich ist. Um die
Entflechtung bezüglich der Leiterbahnen auf bzw. durch die
Leiterplatte hindurch nicht zu erschweren, ist es vorteilhaft,
wenn die Anschlußbohrungen für die Masseanschlüsse am
vorderen Rand der Baugruppe und/oder hinter den Signalanschlußreihen
15 wie dargestellt in einer Linie 14 liegen. Angedeutet
in den Figuren 3 und 4 ist auch die Lage jeweils einer
Abschirmeinheit 3. In Figur 4 ist eine alternative Kontaktierung
dargestellt, bei der Druckkontakte, mit einer großen
plastischen Verformbarkeit und einer ausreichend großen
elastischen Rückkstellwirkung, zwischen den Signalanschlußreihen
15 liegen.For practical applications, it is advantageous if, as in the embodiments according to FIGS. 1 and 2, the
It is electrically more favorable if, as shown in FIGS. 1 and 2, at least one second press-in
Das erfindungsgemäße Verbinderelement eignet sich demnach besonders
zur Kombination mit einer Leiterplatte, wobei sich
die Einpreßanschlüsse und die einpreßbaren Masseanschlüsse 7
und 13 in die Leiterplatte erstrecken. Ermöglicht werden dadurch
Anordnungen, bestehend aus einem erfindungsgemäßen Verbinderelement
bzw. einer erfindungsgemäßen Kombination mit
einer Federleisten-Leiterplatte, und aus einer damit durch
Stecken verbindbaren Kombination einer Messerleiste mit einer
weiteren Leiterplatte. Die Erfindung ist insbesondere erfolgreich
im Zusammenhang mit der SIPAC (eingetragenes Warenzeichen)-High
Speed Steckverbinderfamilie der Firma Siemens einsetzbar.The connector element according to the invention is therefore particularly suitable
to combine with a printed circuit board, whereby
