Description

Die Erfindung betrifft eine Leiterplattensteckverbindung zur Verbindung rechtwinklig angeordneter, mit Leiterbahnen versehener Leiterplatten, bestehend aus einem ersten Steckverbinder mit einem Isolierkörper und einem mit Kontaktbuchsen versehenen Steckbereich und einem zweiten Steckverbinder mit einem Isolierkörper und einem mit Kontaktstiften versehenen Steckbereich, die jeweils auf einer der Leiterplatten befestigt sind.The invention relates to a printed circuit board connector for connecting rectangularly arranged, provided with conductor tracks printed circuit boards, consisting of a first connector with an insulating body and a plug area provided with contact sockets and a second connector with an insulating body and a plug area provided with contact pins, each fastened to one of the circuit boards are.

Die Leiterplattensteckverbindung ist vorzugsweise für den Einsatz in modular aufgebauten Signalverarbeitungssystemen mit einer Rückwand-Leiterplatte und diversen Einschubleiterplatten vorgesehen, bei denen aufgrund eines weiteren Signalangebotes ein erhöhter oder zusätzlicher Bedarf an steckbaren elektrischen Kontakten besteht.The printed circuit board connector is preferably provided for use in modular signal processing systems with a backplane printed circuit board and various plug-in printed circuit boards in which there is an increased or additional need for pluggable electrical contacts due to a further signal offering.

Aus der DE-C-198 52 290 ist ein elektrischer Steckverbinder für gedruckte Leiterplatten, insbesondere Rückwandsteckverbinder, bekannt, bei dem zur Steckung einer 3-reihigen Federleiste in einem mit fünf Stiftreihen ausgebildeten Steckverbinder ein Adapter eingerastet wird, in den eine 3-reihige Federleiste einsetzbar ist.From DE-C-198 52 290 an electrical connector for printed circuit boards, in particular backplane connectors, is known, in which an adapter is latched into a connector designed with five rows of pins for the insertion of a 3-row female connector into which a 3-row female connector can be used.

Aus der DE-A-25 25 864 ist für eine Anordnung zur Erhöhung der Kontaktanzahl bei Steckverbindern von steckbaren Flachbaugruppen bekannt, bei der Kontaktleisten aufeinandergesetzt werden, aus denen Anschlußfahnen herausragen. Zwischen diese Anschlußfahnen wird eine biegsame Folie, die um ein Füllstück herumgelegt wird, eingeschoben. Dabei sind die auf der biegsamen Folie vorhandenen gedruckten Leiterbahnen mit den Leiterbahnen auf einer Leiterplatte fest verlötet.From DE-A-25 25 864 is known for an arrangement for increasing the number of contacts in connectors of pluggable printed circuit boards, in which contact strips are placed on top of one another, from which connecting lugs protrude. A flexible film, which is placed around a filler piece, is inserted between these connecting lugs. The printed conductor tracks on the flexible film are firmly soldered to the conductor tracks on a circuit board.

Aus der DE-U-89 05 434 ist eine Anordnung zur Erhöhung der Kontaktzahl bei Leiterplattensteckverbindern bekannt, bei der eine Leiterplatte stirnseitig vor einem im wesentlichen quaderförmigen Isolierkörper angeordnet ist, in dem eine Vielzahl von Kontaktelementen angeordnet sind. Dabei sind erste und zweite Kontaktelemente mit je einer Leiterfolie verbunden, die ober- und unterhalb der Leiterplatte Kontaktierungsflächen zugeordnet sind, während dritte Kontaktelemente als Anschlußmittel direkt mittels starrer Lötfahnen an der Leiterplatte den Leiterplattensteckverbinder kontaktieren.From DE-U-89 05 434 an arrangement for increasing the number of contacts in printed circuit board connectors is known, in which a printed circuit board is arranged on the front side in front of an essentially cuboidal insulating body in which a multiplicity of contact elements are arranged. First and second contact elements are each connected to a conductor foil, which are assigned contact surfaces above and below the circuit board, while third contact elements contact the circuit board connector directly as connection means by means of rigid soldering lugs on the circuit board.

Es ist allgemein bekannt, eine elektrische Signalverteilung mittels Leiterplattensteckverbindern in den verschiedensten Ausführungen mit entsprechend geführten Leiterbahnen, die in einer Busstruktur auf einer rückwärtigen Leiterplatte als Busplatine zusammengefaßt sind, vorzunehmen. Trotz zunehmender Integration der elektronischen Bauteile nehmen jedoch auch die zu verteilenden und zu verarbeitenden Signale zu. Des weiteren sind immer höhere Verarbeitungsgeschwindigkeiten gefordert, die mit einem reinen elektrischen System nicht mehr zu bewältigen sind. Insofern bietet sich für eine Signalverteilung auch eine Kombination von elektrischen und optischen Signalen an. Dazu müssen aber optoelektrische Wandler in die Signalverteilung eingefügt werden, die in der Regel eine zusätzliche optoelektrische Steckverbindung erfordern.It is generally known to carry out an electrical signal distribution by means of printed circuit board connectors in a wide variety of designs with appropriately guided conductor tracks which are combined in a bus structure on a rear printed circuit board as a bus board. Despite the increasing integration of electronic components, however, the signals to be distributed and processed are also increasing. Furthermore, ever higher processing speeds are required, which can no longer be managed with a purely electrical system. In this respect, a combination of electrical and optical signals is also suitable for signal distribution. To do this, however, optoelectric converters must be inserted into the signal distribution, which usually require an additional optoelectric plug connection.

Der Erfindung liegt daher die Aufgabe zugrunde, eine elektrische Leiterplattensteckverbindung der eingangs genannten Art dahingehend auszubilden, dass neben den Signalleitungen für einen Einsatz mit herkömmlichen, bekannten Steckverbindern zusätzliche elektrische Signale von einer Leiterplatte zu einer weiteren Leiterplatte übermittelt werden können, wobei kein zusätzlicher Steckverbinder benötigt wird.The invention is therefore based on the object of designing an electrical circuit board connector of the type mentioned in such a way that, in addition to the signal lines for use with conventional, known connectors, additional electrical signals can be transmitted from one circuit board to another circuit board, no additional connector being required ,

Diese Aufgabe wird bei einer Steckverbindung der eingangs genannten Art dadurch gelöst, dass am Isolierkörper des ersten Steckverbinders eine Leiterfolie angebracht ist, die ein erstes Anschlussende aufweist, das am Isolierkörper des ersten Steckverbinders auf der von der Leiterplatte abgewandten Seite halten ist, und ein zweites Anschlussende, das zwischen einer Auflagefläche des ersten Steckverbinders und der Leiterplatte angeordnet ist, wobei Kontaktbahnen am zweiten Anschlussende der Leiterfolie zu Kontaktflächen der Leiterbahnen auf der Leiterplatte weisen, und dass auf dem Isolierkörper des zweiten Steckverbinders ein Isoliergehäuse mit einem Schlitz vorgesehen ist, in dem elektrische Kontakte angeordnet sind, wobei beim Zusammenstecken der Steckverbinder das erste Anschlussende der Leiterfolie in den Schlitz eintaucht und die elektrischen Kontakte mit den Kontaktbahnen der Leiterfolie in elektrischen Kontakt gelangen.This object is achieved in the case of a plug connection of the type mentioned at the outset in that a conductor film is attached to the insulating body of the first connector and has a first connection end which is held on the insulating body of the first connector on the side facing away from the printed circuit board, and a second connection end , which is arranged between a support surface of the first connector and the printed circuit board, contact tracks at the second connection end of the conductor foil pointing to contact areas of the conductive tracks on the printed circuit board, and that an insulating housing with a slot is provided on the insulating body of the second connector in which electrical contacts are arranged, the first connection end of the conductor film being immersed in the slot when the plug connectors are plugged together and the electrical contacts coming into electrical contact with the contact tracks of the conductor film.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass neben dem normalen bekannten Steckbereich bei Leiterplattensteckverbindern ein zusätzlicher Steckbereich genutzt wird, um zusätzliche elektrische Signale zu übertragen, so dass eine höhere Datenübertragungsrate erzielbar ist, wobei bereits bestehende Stecksysteme mit dieser Leiterplattensteckverbindung nachträglich ausgerüstet werden können. Weiterhin ist von Vorteil, dass dieser zweite, zusätzliche Steckbereich gleichzeitig mit dem ersten Steckbereich steckbar ist.The advantages achieved by the invention consist in particular in that, in addition to the normal known plug-in area in printed circuit board connectors, an additional plug-in area is used to transmit additional electrical signals, so that a higher data transmission rate can be achieved, with existing plug-in systems being retrofitted with this printed circuit board connector can. It is also advantageous that this second, additional plug-in area can be plugged in simultaneously with the first plug-in area.

Ein weiter Vorteil ergibt sich durch die Nutzung einer beidseitig mit Kontaktbahnen versehenen Leiterfolie zur Signalübertragung, so dass auf der steckbaren Leiterplatte keine zusätzlichen Kontaktbahnen zu den Kontakten des regulären und eventuell mit einer höheren Kontaktanzahl versehen Steckverbinders vorgesehen werden müssen.A further advantage results from the use of a conductor foil provided on both sides with contact tracks for signal transmission, so that no additional contact tracks need to be provided on the pluggable printed circuit board for the contacts of the regular connector and possibly with a higher number of contacts.

Die elektrischen Signale werden durch eine spezielle für Leiterfolien optimierte Kontaktierungsart direkt von den Leiterbahnen der Leiterplatte auf die Kontaktbahnen der Leiterfolie übertragen, wobei ein gegenseitiger Andruck der Leiterbahnen und deren elektrische Kontaktierung mittels eines Kontaktelementes erfolgt.The electrical signals are transmitted directly from the conductor tracks of the printed circuit board to the contact tracks of the conductor foil by a special type of contacting optimized for conductor foils, whereby the conductor tracks are pressed against one another and their electrical contacting takes place by means of a contact element.

Besonders vorteilhaft ist, dass im Isoliergehäuse des zweiten Steckbereiches optoelektrische Elemente vorsehbar sind, die elektrisch steckbar sind und deren optische Eigenschaften, die ein Vielfaches der Datenübertragung eines reinen elektrischen Systems aufweisen, über entsprechend vorgesehene optische Datenleitungen und weitere optische Elemente optimal zu nutzen sind.It is particularly advantageous that optoelectric elements can be provided in the insulating housing of the second plug-in area, which can be plugged in electrically and whose optical properties, which have a multiple of the data transmission of a pure electrical system, can be optimally used via correspondingly provided optical data lines and further optical elements.

  • 3 is an isometric view of a first connector,
  • Fig. 4 is an isometric view of a second connector, and
  • Fig. 5 is an isometric view of an upper insulating housing.

In der Fig. 1 ist in einer Schnittansicht eine gesteckte Leiterplattenverbindung dargestellt, die aus einem gewinkelten Steckverbinder 1 und einem geraden Steckverbinder 2 gebildet wird.In Fig. 1, a plug-in circuit board connection is shown in a sectional view, which is formed from an angled connector 1 and a straight connector 2.

Der Steckverbinder 2 ist als U-förmiger Isolierkörper 20 mit asymmetrischen Seitenschenkeln ausgebildet, in dessen Steckbereich 21 in Spalten und Reihen angeordnete Stiftkontakte 22 vorgesehen sind, die auf ihrer entgegengesetzten Seite in Bohrungen auf einer Leiterplatte 8 eintauchen.The plug connector 2 is designed as a U-shaped insulating body 20 with asymmetrical side legs, in the plug-in region 21 of which pin contacts 22 are provided in columns and rows, which plunge into holes on a printed circuit board 8 on their opposite side.

Auf dem verlängerten Seitenschenkel des Isolierkörpers 20 des Steckverbinders 2 ist ein Isoliergehäuse 23 vorgesehen, das einstückig am Isolierkörper 20 angeformt sein kann oder auch als zusätzliches Isoliergehäuse mit dem Isolierkörper 20 verbunden sein kann.On the extended side leg of the insulating body 20 of the connector 2, an insulating housing 23 is provided which can be integrally formed on the insulating body 20 or can also be connected to the insulating body 20 as an additional insulating housing.

Der Steckverbinder 1 ist mit (nicht gezeigten) Federkontakten versehen, die bei ineinander eingesteckten Steckverbindern den elektrischen Kontakt der Leiterplattensteckverbindung mit den Stiftkontakten 22 des Steckverbinders 2 sichergestellt. In Richtung der Leiterplatte ist der Steckverbinder 1 mit einer Anformung 12 versehen, in der Kontaktelemente 4 vorgesehen sind, die eine elektrische Verbindung von Leiterbahnen 6 der Leiterplatte 5 auf Kontaktbahnen 33 einer flexiblen Leiterfolie 3 ermöglichen. Die Anzahl der Kontaktelemente 4, die in Ausnehmungen 13 geführt sind, entsprechen der Anzahl der Kontaktbahnen auf der flexiblen Leiterfolie 3.The connector 1 is provided with spring contacts (not shown) which, when the connectors are inserted one into the other, ensure the electrical contact of the printed circuit board connector with the pin contacts 22 of the connector 2. In the direction of the printed circuit board, the plug connector 1 is provided with a molded part 12, in which contact elements 4 are provided, which enable an electrical connection of printed conductors 6 of the printed circuit board 5 to contact tracks 33 of a flexible printed circuit film 3. The number of contact elements 4, which are guided in recesses 13, correspond to the number of contact tracks on the flexible conductor foil 3.

Die flexible Leiterfolie 3, in der Fig. 2 vergrößert dargestellt, besteht aus einer biegsamen Trägerfolie 30, auf der beidseitig ebenfalls biegsame Kontaktbahnen 33, 35 zur Übertragung elektrischer Signale aufgebracht sind, wobei die Leiterfolie, in diesem Beispiel kreisförmig gebogen, eine zweite elektrische Signalübertragungsebene zum oberen Isoliergehäuse 23 des Steckverbinders 2 bildet.The flexible conductor foil 3, shown enlarged in FIG. 2, consists of a flexible carrier foil 30, on which flexible contact tracks 33, 35 are likewise applied on both sides for the transmission of electrical signals, the conductor foil, in this example curved in a circle, having a second electrical signal transmission plane to the upper insulating housing 23 of the connector 2 forms.

Der waagrechte Federschenkel 42 ist an seinem Ende mit einer zur Leiterplatte weisenden Verrundung 43 versehen. Aufgrund der Hebelwirkung des mit dem stiftförmigen Ende 44 versehenen Schenkels 41, durch die Befestigung des stiftförmigen Endes 44 in der Bohrung der Leiterplatte und des senkrechten Schenkels 41 in der Ausnehmung 13, wird die Verrundung 43 des waagrechten Federschenkels 42 ständig in Richtung auf die Oberfläche der Leiterplatte 5 gedrückt.The vertical leg 41 of the contact element 4, further shown in FIG. 1 within the formation 12, is provided with a pin-shaped end 44 which extends beyond the horizontally shown spring leg 42 and which dips into a bore on the printed circuit board 5 and is electrically conductive there with the conductor track 7 is connected. The horizontal spring leg 42 is provided at its end with a rounding 43 pointing towards the printed circuit board. Due to the leverage of the leg 41 provided with the pin-shaped end 44, by fastening the pin-shaped end 44 in the bore of the printed circuit board and the vertical leg 41 in the recess 13, the rounding 43 of the horizontal spring leg 42 is constantly in the direction of the surface of the Printed circuit board 5 pressed.

Zwischen den Kontaktelementen 4 und der Leiterplatte 5 ist die flexible Leiterfolie 3 angeordnet. Die Leiterfolie ist unmittelbar vor dem Anschlussende 32 mit runden Öffnungen 34 versehen, durch die die stiftförmigen Enden 44 der Kontaktelemente 4 hindurchgreifen, so dass beim Eintauchen der Enden 44 in entsprechende Bohrungen in der Leiterplatte 5, das Anschlussende 32 der Leiterfolie am Steckverbinderteil 1 gehalten ist. Mittels der Kontaktelemente 4 wird die Leiterfolie 3 mit den beidseitig aufgebrachten Kontaktbahnen 33, 35 an die Leiterplatte 5 angepreßt. Dabei kontaktieren die äußeren Kontaktbahnen 33 durch den Andruck der Verrundungen 43 der Kontaktelemente 4 die entsprechend angeordneten Leiterbahnen 6 oberhalb der Leiterplatte 5, während die innen liegenden Kontaktbahnen 35 direkt mit den Verrundungen 43 des waagrechten Schenkels kontaktieren und mittels der stiftförmigen Enden 44 des Kontaktelementes 4 eine elektrische Verbindung zu den Leiterbahnen 7 unterhalb der Leiterplatte 5 hergestellt wird.The flexible conductor foil 3 is arranged between the contact elements 4 and the circuit board 5. Immediately before the connection end 32, the conductor film is provided with round openings 34, through which the pin-shaped ends 44 of the contact elements 4 extend, so that when the ends 44 are immersed in corresponding bores in the printed circuit board 5, the connection end 32 of the conductor film is held on the connector part 1 , By means of the contact elements 4, the conductor foil 3 with the contact tracks 33, 35 applied on both sides is pressed onto the printed circuit board 5. The outer contact tracks 33 contact the correspondingly arranged conductor tracks 6 above the printed circuit board 5 by pressing the rounded portions 43 of the contact elements 4, while the inner contact tracks 35 directly contact the rounded portions Contact 43 of the horizontal leg and an electrical connection to the conductor tracks 7 below the circuit board 5 is made by means of the pin-shaped ends 44 of the contact element 4.

Die Fig. 3 zeigt eine isometrische Darstellung des Steckverbinders 1 im nicht gesteckten Zustand, so dass neben dem normalen Steckbereich 11 des Steckverbinders, deutlich die zweite durch die Leiterfolie 3 gebildete, aufgesetzte Steckebene erkennbar ist. Oberhalb des Isolierkörpers 10 sind drei blockartige Abstandhalter 14 auf der der Leiterplatte abgewandten Seite des Steckverbinders 1 vorgesehen, auf denen die flexible Leiterfolie 3 mit nietähnlichen Befestigungsmitteln 15 gehalten ist. In den zwischen den Abstandhaltern liegenden Freiräumen sind auf der Leiterfolie 3 die Kontaktbahnen 33, 35 angeordnet, wobei das Anschlußende 31 beim Zusammenstecken in den Schlitz 24 des komplementären Steckverbinders 2 eingefügt wird.3 shows an isometric view of the connector 1 when it is not plugged in, so that in addition to the normal plug-in area 11 of the connector, the second plug-in level formed by the conductor foil 3 can be clearly seen. Above the insulating body 10, three block-like spacers 14 are provided on the side of the connector 1 facing away from the printed circuit board, on which the flexible conductor foil 3 is held with rivet-like fastening means 15. In the free spaces lying between the spacers, the contact tracks 33, 35 are arranged on the conductor foil 3, the terminal end 31 being inserted into the slot 24 of the complementary connector 2 when plugged together.

In der Fig. 4 ist eine isometrische Darstellung des Steckverbinders 2 gezeigt, bei dem der Isolierkörper 20 mit asymmetrischen U-förmigen Schenkeln ausgebildet ist, innerhalb derer der Steckbereich 21 mit den Kontaktstiften 22 vorgesehen ist. Im bzw. oberhalb des verlängerten Schenkels des Isolierkörpers 20 ist das Isoliergehäuse 23 mit einem durch Ausnehmungen 26 unterbrochenen und begrenzten Schlitz 24 vorgesehen, in dem mindestens federnde Kontakte 25 sowie weitere elektrische Kontakte 29 angeordnet sind. Für die Abstandhalter 14 auf dem Isolierkörper 10 des Steckverbinders 1 sind im Isoliergehäuse 23 und im Isolierkörpers 20 entsprechende Ausnehmungen 26 vorgesehen, die ein Einfügen des Anschlussendes 31 der Leiterfolie 3 in den Schlitz 24 des Steckverbinders 2 ermöglichen.4 shows an isometric illustration of the plug connector 2, in which the insulating body 20 is formed with asymmetrical U-shaped legs, within which the plug region 21 with the contact pins 22 is provided. In or above the extended leg of the insulating body 20, the insulating housing 23 is provided with a slot 24 which is interrupted and delimited by recesses 26 and in which at least resilient contacts 25 and further electrical contacts 29 are arranged. For the spacers 14 on the insulating body 10 of the connector 1, corresponding recesses 26 are provided in the insulating housing 23 and in the insulating body 20, which enable insertion of the connection end 31 of the conductor foil 3 into the slot 24 of the connector 2.

Während des Steckvorganges wird das Anschlussende 31 der Leiterfolie 3 in den Schlitz 24 eingeschoben, wobei die unterhalb der Leiterfolie angeordneten, federnden Kontakte 25 auf die Kontaktbahnen 35 zugreifen und gleichzeitig die oberen Kontaktbahnen 33 gegen die elektrischen Kontakte 29 gedrückt werden. Der Schlitz 24 ist zum leichteren Einfügen der Leiterfolie durch eine beidseitige, trichterförmige Einführöffnung aufgeweitet.During the plugging process, the connection end 31 of the conductor foil 3 is inserted into the slot 24, the one below the conductor foil Arranged, resilient contacts 25 access the contact tracks 35 and at the same time the upper contact tracks 33 are pressed against the electrical contacts 29. The slot 24 is widened for easier insertion of the conductor foil through a funnel-shaped insertion opening on both sides.

Die Funktionsweise der Kontaktierung zwischen den Kontakten und den Kontaktbahnen der Leiterfolie ist ähnlich der bereits bei der Leiterplatte 5 beschriebenen Kontaktierung. Die Kontaktelemente 25 unterhalb der flexiblen Leiterfolie 3 übernehmen die Signale der unteren Kontaktbahnen 35, während oberhalb angeordneten elektrischen Kontakte 29 die Signale der oberen Kontaktbahnen 33 übernehmen und weiterleiten.The functioning of the contacting between the contacts and the contact tracks of the conductor foil is similar to the contacting already described for the printed circuit board 5. The contact elements 25 below the flexible conductor foil 3 take over the signals of the lower contact tracks 35, while electrical contacts 29 arranged above take over and forward the signals of the upper contact tracks 33.

In dem Beispiel ist vorgesehen, die unteren Kontaktbahnen 35 der Leiterfolie 3 zur Abschirmung vorzusehen, wobei die über die Kontaktelemente 25 ausgekoppelten Signale mittels eines innerhalb des Isoliergehäuses 23 eingelassenen flächigen Abschirmbleches 27 und mittels daran angeformter Federkontakte 28, an eine dafür vorgesehene Leiterbahn auf der Leiterplatte 8 weitergeleitet werden.In the example, provision is made for the lower contact tracks 35 of the conductor foil 3 to be shielded, the signals decoupled via the contact elements 25 by means of a flat shield plate 27 embedded in the insulating housing 23 and by means of spring contacts 28 molded thereon, to a conductor track provided for this purpose on the printed circuit board 8 be forwarded.

Die Fig. 5 zeigt in einer isometrischen Darstellung das vom Isolierkörper 20 entfernte Isoliergehäuse 23 des Steckverbinders 2 in dem die hier sichtbaren elektrischen Kontakte 29 angeordnet sind. Innerhalb des Isoliergehäuses 23 sind hier nicht gezeigte optoelektrische Wandler vorgesehen, deren elektrische Anschlüsse mit den elektrischen Kontakten 29 verbunden sind und deren optischer Anschluss mit aus dem Isoliergehäuse herausgeführten Lichtwellenleitern 9 verbunden ist. Das Isoliergehäuse 23 kann einstückig mit dem Isolierkörper 20 verbunden sein, kann aber auch - wie in diesem Beispiel gezeigt - getrennt auf den Isolierkörper 20 aufsetzbar ausgebildet sein.5 shows an isometric view of the insulating housing 23 of the plug connector 2, which is removed from the insulating body 20 and in which the electrical contacts 29 visible here are arranged. Optoelectric converters, not shown here, are provided within the insulating housing 23, the electrical connections of which are connected to the electrical contacts 29 and the optical connection of which is connected to optical waveguides 9 led out of the insulating housing. The insulating housing 23 can be connected in one piece to the insulating body 20, but can also - as shown in this example - be designed to be placed separately on the insulating body 20.
