Abstract

The invention relates to a multipin electrical plug connector. The invention is based on the object of designing a multipin plug connector such that plug-in processes during operation with a power supply do not lead to undesirable charging or discharging processes in the connected circuit parts, irrespective of the size of the plug connector parts. For this purpose, in addition to the contact pins, the plug connector has at least one guide or contact pin (12) of larger geometrical dimensions than the other contact pins (11) and a greater mechanical and electrical load capability. The guide or contact pins (12) can be arranged asymmetrically in the two-dimensional contact pin arrangement and can have different guide pins with respect to the contact pins. <IMAGE>

Description

Die Erfindung betrifft eine mehrpolige elektrische Steck­verbindung, bestehend aus in einem zweidimensionalen Feld mit einer Quer- und Längsachse angeordneten Kontaktstif­ten und korrespondierenden Kontaktfedern.The invention relates to a multi-pole electrical connector, consisting of contact pins arranged in a two-dimensional field with a transverse and longitudinal axis and corresponding contact springs.

Bei mehrpoligen Steckverbindungen weisen die einzelnen Kontaktstifte regelmäßig unterschiedliche geometrische Abmessungen in Steckrichtung auf. Beim Ein- und Aus­stecken von Steckern in bzw. aus Steckaufnahmeelementen könne diese Toleranzen sowie eine unpräzise manuelle Führung des oder der beweglichen Steckverbindungsteile während des Betriebs mit einer Spannungsversorgung zu un­erwünschten Auf- bzw. Entladevorgängen in Schaltungstei­len führen, die an die Steckverbindung angeschlossen sind. Zur Lösung derartiger Probleme sind bereits Steck­verbindungen bekannt geworden, die sogenannte voreilende Kontaktstifte besitzen. Die voreilenden Kontaktstifte sind beim Ein- und Ausstecken, wenn nur sie, nicht aber die übrigen Kontaktstifte in den Stiftaufnahmeelementen gleiten, hohen mechanischen Beanspruchungen ausgesetzt. Dies gilt insbesondere dann, wenn, wie beispielsweise in Baugruppensystemen eines der beiden Steckverbindungsteile eine erhebliche Masse aufweist.In the case of multi-pole plug connections, the individual contact pins regularly have different geometrical dimensions in the plug direction. When plugging and unplugging plugs in or out of plug-in receptacle elements, these tolerances and an imprecise manual guiding of the movable plug-in connector part or parts during operation with a voltage supply can lead to undesired charging or discharging processes in circuit parts which are connected to the plug-in connection. To solve such problems, plug connections are already known which have so-called leading contact pins. The leading contact pins are subjected to high mechanical stresses when inserting and removing, if only they, but not the other contact pins, slide in the pin receiving elements. This applies in particular if, as in assembly systems, for example, one of the two plug connection parts has a considerable mass.

Der Erfindubg liegt die Aufgabe zugrunde, eine mehrpolige Steckverbindung so auszubilden, daß Steckvorgänge unab­hängig von der Masse der Steckverbindungsteile während des Betriebs mit einer Spannungsversorgung nicht zu uner­ wünschten Auf- bzw. Entladevorgängen in angeschlossenen Schaltungsteilen führen.The invention is based on the object of designing a multi-pole plug connection in such a way that plugging operations are not uncommon regardless of the mass of the plug connection parts during operation with a voltage supply desired charging or discharging processes in connected circuit parts.

Diese Aufgabe wird in einer Vorrichtung der eingangs ge­nannten Art gemäß dem kennzeichnenden Teil des ersten Pa­tentanspruchs gelöst.This object is achieved in a device of the type mentioned in the opening paragraph according to the characterizing part of the first claim.

Als vorteilhaft erweist sich, daß erfindungsgemäße mehr­polige Steckverbindungen, beispielsweise in Baugruppensy­stemen, besondere anderweitige Vorrichtungen zur Führung, wie Führungsschienen, nicht benötigen bzw. daß diese an­derweitigen Führungsvorrichtungen entlastet werden und nur eine unterstützende Funktion innehaben.It has proven to be advantageous that multi-pole plug connections according to the invention, for example in assembly systems, do not need any special other devices for guiding, such as guide rails, or that these other guiding devices are relieved and only have a supporting function.

Die asymmetrische Anordnung der Führungsstifte verhindert Fehler beim Zusammenstecken der Steckverbindungsteile.The asymmetrical arrangement of the guide pins prevents errors when plugging the connector parts together.

Die Ausbildung von Führungsstiften als Kontaktstifte er­möglicht, die Zahl der Kontaktstifte in erfindundsgemäßen Steckverbindunden zu reduzieren.The formation of guide pins as contact pins makes it possible to reduce the number of contact pins in plug-in connections according to the invention.

Die Erfindung wird nun anhand der Zeichnungen in einem zum Verständnis erforderlichen Umfang beschrieben. Es zeigen:

  • FIG 1 einen Teil eines Baugruppensystems mit einer mehr­poligen elektrischen Steckverbindung gemäß der Erfindung,
  • FIG 2 einen Teil einer mehrpoligen elektrischen Steckver­bindung mit Kontaktstiften und einem Führungsstift,
  • FIG 3 verschiedene Anordnungen von Kontakt- und Füh­rungsstiften.
The invention will now be described with reference to the drawings to the extent necessary for understanding. Show it:
  • 1 shows a part of an assembly system with a multi-pole electrical connector according to the invention,
  • 2 shows a part of a multi-pole electrical plug connection with contact pins and a guide pin,
  • 3 different arrangements of contact and guide pins.

Der in FIG 1 dargestellte Teil eines Baugruppensystems besteht aus einer Rückwandleiterplatte 1 mit einer Zen­ trierleiste 13 und aus einer Leiterplatte 2 mit einer Fe­derleiste 21.The part of an assembly system shown in FIG. 1 consists of a backplane 1 with a zen Trierleiste 13 and from a circuit board 2 with a female connector 21st

In der Rückwandleiterplatte 1 sind, wie in FIG 1 schema­tisch gezeigt, sowohl eine Mehrzahl Kontaktstifte 11 als auch mindestens ein Führungsstift 12 befestigt. Der bzw. die Führungsstifte 12 weisen größere geometrische Abmes­sungen als die Kontaktstifte 11 auf und sind durch ihr Material und/oder ihren Aufbau in höherem Maß mechanisch und/oder elektrisch belastbar als die Kontaktstifte 11. Die Anordnung der Stifte 11 und 12 zueinander wird unten anhand von FIG 3 beschrieben.As schematically shown in FIG. 1, both a plurality of contact pins 11 and at least one guide pin 12 are fastened in the rear wall circuit board 1. The guide pin or pins 12 have larger geometrical dimensions than the contact pins 11 and, due to their material and / or their structure, are mechanically and / or electrically loadable to a greater extent than the contact pins 11. The arrangement of the pins 11 and 12 with respect to one another is described below described by FIG 3.

Die Zentrierleiste 13 wird so über die Kontaktstifte 11 und die Führungsstifte 12 geschoben, daß sie unmittelbar auf der Rückwandleiterplatte 1 aufliegt und die Stifte 11 und 12 in das Innere der Zentrierleiste 13 ragen. Sie weist hierzu entsprechende Öffnungen zur Aufnahme der Stifte 11 und 12 auf und verleiht diesen im montierten Zustand zusätzlichen Halt. Einzelheiten werden unten an­hand von FIG 2 beschrieben. Wie der Name der Zentrierlei­ste 13 andeutet, dient sie der Zentrierung beider Teile der erfindungsgemäßen mehrpoligen elektrischen Steckver­bindung.The centering strip 13 is pushed over the contact pins 11 and the guide pins 12 so that it lies directly on the backplane 1 and the pins 11 and 12 protrude into the interior of the centering strip 13. For this purpose, it has corresponding openings for receiving the pins 11 and 12 and gives them additional hold in the assembled state. Details are described below with reference to FIG 2. As the name of the centering strip 13 indicates, it serves to center both parts of the multi-pole electrical connector according to the invention.

Die Federleiste 21 weist Aufnahmeöffnungen 211 für die Kontaktstifte 11 auf. Im Inneren der Federleiste 21 be­finden sich in FIG 1 nicht dargestellte, zu den Kontakt­stiften 11 korrespondierende Kontaktfedern, die in Kon­taktfederreihen Aʹ, Bʹ, Cʹ, Dʹ, Eʹ angeordnet sind. Die Federleiste 21 weist außerdem mindestens eine Aufnahme­öffnung 212 für den bzw. die Führungsstifte 12 auf. Die Führungsstifte 12 können neben ihrer mechanischen Funk­tion der Führung zugleich auch die elektrische Funktion von Kontaktstiften innehaben. In diesem Fall befinden sich für diejenigen Führungsstifte 12, die als Kontakt­stifte ausgebildet sind, im Inneren der Federleiste 21 in FIG 1 nicht dargestellte, zu den Stiften 12 korrespondie­rende Kontaktfedern.The female connector 21 has receiving openings 211 for the contact pins 11. In the interior of the female connector 21 are shown in FIG 1, not shown, corresponding to the contact pins 11 contact springs, which are arranged in rows of contact springs Aʹ, Bʹ, Cʹ, Dʹ, Eʹ. The female connector 21 also has at least one receiving opening 212 for the guide pin (s) 12. In addition to their mechanical function of guiding, the guide pins 12 can also have the electrical function of contact pins. In this case for those guide pins 12, which are designed as contact pins, in the interior of the female connector 21 in FIG. 1, not shown, corresponding to the pins 12 corresponding contact springs.

Die Federleiste 21 ist mit der Leiterplatte 2 fest ver­bunden, beispielsweise mittels an der Federleiste 21 an­geordneter Federleistenbefestigungszapfen 213 und/oder sonstiger Befestigungselemente. Die Anordnung aus Feder­leiste 21 und Leiterplatte 2 kann in Führungsschienen 214 geführt werden.The female connector 21 is fixedly connected to the printed circuit board 2, for example by means of female connector fastening pins 213 arranged on the female connector 21 and / or other fastening elements. The arrangement of female connector 21 and printed circuit board 2 can be guided in guide rails 214.

Die in den Aufnahmeöffnungen 211 und gegebenenfalls 212 der Federleiste 21 angeordneten, in FIG 1 nicht darge­stellten Kontaktfedern, greifen in auf der Leiterplatte 2 angeordnete Anschlußlöcher 20, die ihrerseits mit Leiter­bahnen oder Anschlußreihen A, B, C, D, E verbunden sind. An den Anschlußreihen A, B, C, D, E sind die eigentliche Schaltung bzw. die Schaltungsteile angeschlossen, in de­nen es bei Nichtanwendung der Erfindung zu unerwünschten Auf- bzw. Entladevorgängen beim Ein- bzw. Ausstecken der Steckverbindungsteile 1, 11, 12, 13 und 2, 21, 211, 212, 20 kommen könnte. Die Schaltung bzw. die Schaltungsteile sind in FIG 1 nicht dargestellt.The contact springs, not shown in FIG. 1, arranged in the receiving openings 211 and possibly 212 of the female connector 21 engage in connection holes 20 arranged on the printed circuit board 2, which in turn are connected to conductor tracks or connection rows A, B, C, D, E. The actual circuit or the circuit parts are connected to the connection rows A, B, C, D, E in which, when the invention is not used, there are undesired charging and discharging processes when the plug-in connection parts 1, 11, 12 13 and 2, 21, 211, 212, 20 could come. The circuit or the circuit parts are not shown in FIG. 1.

FIG 2 zeigt schematisch einen Teil einer mehrpoligen elektrischen Steckverbindung mit Kontaktstiften 11 und einem Führungsstift 12. Die Kontaktstifte 11 sind bei­spielsweise in die Rückwandleiterplatte 1 eingepreßt, während der Führungsstift 12 mit der Rückwandleiterplat­te 1 beispielsweise mittels einer Schraube befestigt ist.2 schematically shows part of a multi-pole electrical plug connection with contact pins 11 and a guide pin 12. The contact pins 11 are, for example, pressed into the backplane 1, while the guide pin 12 is fastened to the backplane 1, for example by means of a screw.

Der Führungsstift 12 weist größere geometrische Abmessun­gen auf als die Kontaktstifte 11 und ist aufgrund dieser vergrößerten geometrischen Abmessungen, seines Materials und/oder seines Aufbaus mechanisch und/oder elektrisch stärker belastbar als die Kontaktstifte 11.The guide pin 12 has larger geometric dimensions than the contact pins 11 and is due to this enlarged geometric dimensions, its material and / or its structure can be mechanically and / or electrically stronger than the contact pins 11.

Die Spitzen des Führungsstiftes 12 und der Kontaktstifte 11 weisen in Richtung der in FIG 2 nicht, jedoch in FIG 1 dargestellten Federleiste 21.
Beim Ein- bzw. Ausstecken der Steckverbindung eilt der Führungsstift 12 gegenüber den Kontaktstiften 11 wegen seiner auf die Grenzschicht zwischen Rückwandleiterplatte 1 und Zentrierleiste 13 bezogenen größeren senkrechten Abmessung vor bzw. nach. Die Zentrierleiste 13 weist, wie bereits erwähnt, Öffnungen zur Aufnahme der Stifte 11 und 12 auf. Die Stifte 11 und Zentrierleiste 13 halten sich gegenseitig durch Rastelemente, wie beispielsweise Pocke und federnder Steg. Der gegenüber den Kontaktstiften 11 mechanisch und/oder elektrisch höher belastbare Führungs­stift 12 kann im Bereich der unmittelbar auf der Rückwand­leiterplatte 1 aufliegenden Gehäusewand der Zentrierlei­ste 13 als Sechskantbund ausgebildet sein und wird dann durch eine entsprechend sechskantförmige Öffnung dieser Gehäusewand der Zentrierleiste 13 umschlossen.The tips of the guide pin 12 and the contact pins 11 point in the direction of the female connector 21 not shown in FIG. 2, but in FIG. 1.
When the plug connection is plugged in or unplugged, the guide pin 12 hurries before and after the contact pins 11 because of its larger vertical dimension, which relates to the boundary layer between the backplane 1 and centering strip 13. As already mentioned, the centering bar 13 has openings for receiving the pins 11 and 12. The pins 11 and centering bar 13 hold each other by means of locking elements such as smallpox and resilient web. The guide pin 12, which is mechanically and / or electrically more resilient than the contact pins 11, can be formed as a hexagon collar in the area of the housing wall of the centering strip 13 lying directly on the backplane 1 and is then enclosed by a corresponding hexagonal opening of this housing wall of the centering strip 13.

Der Führungsstift 12 kann ebenfalls als Kontaktstift aus­gebildet sein. Er besteht dann selbstverständlich aus elektrisch leitfähigem Material und ihm ist eine korres­pondierende Kontaktfeder zugeordnet. Die Schraubbefesti­gung von Führungsstiften 12 auf der Rückwandleiterplatte 1 ermöglicht das Auswechseln von (elektrisch nicht lei­tenden) Führungsstiften in leitende Kontaktstifte, von Kontaktstiften in bloße Führungsstifte sowie das Auswech­seln von Führungsstiften bzw. Kontaktstiften 12 unter­schiedlicher Querschnitte, worauf im Zusammenhang mit FIG 3 noch eingegangen wird. Auf diese Weise läßt sich die erfindungsgemäße mehrpolige elektrische Steckverbin­dung in unterschiedlicher Weise ausbilden.The guide pin 12 can also be designed as a contact pin. Of course, it then consists of electrically conductive material and it is assigned a corresponding contact spring. The screw fastening of guide pins 12 on the backplane 1 enables the exchange of (electrically non-conductive) guide pins into conductive contact pins, of contact pins into mere guide pins and the exchange of guide pins or contact pins 12 of different cross-sections, which will be discussed in connection with FIG. 3. In this way, the multi-pole electrical connector according to the invention can be designed in different ways.

Auch bloße, nicht als Kontaktstifte fungierende Führungs­stifte können aus elektrisch leitfähigem Material beste­hen, so daß sich ein Auswechseln eines Stiftes bei Ergän­zung der mechanischen Führungsfunktion um die elektrische Kontaktierungsfunktion erübrigt. Bei Verwendung gleicher Rückwandleiterplatten 1 und Zentrierleisten 13 weisen die Führungs- bzw. Kontaktstifte an ihrem Fuß jeweils die gleiche Form auf, also beispielsweise die Form eines Sechskants im Bereich der auf der Rückwandleiterplatte 1 aufliegenden Gehäusewand der Zentrierleiste 13.Even bare guide pins that do not function as contact pins can be made of electrically conductive material, so that there is no need to replace a pin when the mechanical guide function is supplemented by the electrical contacting function. When using the same backplane 1 and centering strips 13, the guide or contact pins each have the same shape at their base, for example the shape of a hexagon in the region of the housing wall of the centering strip 13 resting on the backplane 1.

FIG 3 zeigt verschiedene Anordnungen von Kontaktstiften 11 und Führungsstiften 12. Die Kontaktstifte 11 und Füh­tungsstifte 12 sind jeweils in einem zweidimensionalen Feld mit einer Quer- und Längsachse angeordnet.3 shows various arrangements of contact pins 11 and guide pins 12. The contact pins 11 and guide pins 12 are each arranged in a two-dimensional field with a transverse and longitudinal axis.

Die voreilenden Führungsstifte 12 bzw. Kontaktstifte 11 können, wie in FIG 1 dargestellt, symmetrisch zur Mittel­achse eines zweidimensionalen Feldes liegen; sie können aber auch, wie FIG 3a, 3b und 3c zeigen, asymmetrisch ge­genüber der Querachse und/oder gegenüber der Längsachse angeordnet sein. So zeigt FIG 3a beispielsweise zwei ge­genüber der Querachse asymmetrisch angeordnete Führungs- bzw. Kontaktstifte. FIG 3b zeigt eine Anordnung von drei Führungs- bzw. Kontaktstiften 12, von denen zwei auf der Längsachse liegen, jedoch asymmetrisch gegenüber der Querachse angeordnet sind, wobei der dritte Führungs­bzw. Kontaktstift 12 auf der Querachse angeordnet ist. FIG 3c zeigt eine Anordnung mit zwei Führungs- bzw. Kon­taktstiften 12, von denen je einer auf der Quer- und Längsachse liegt.The leading guide pins 12 or contact pins 11 can, as shown in FIG. 1, lie symmetrically to the central axis of a two-dimensional field; but they can also, as shown in FIGS. 3a, 3b and 3c, be arranged asymmetrically with respect to the transverse axis and / or with respect to the longitudinal axis. For example, FIG. 3a shows two guide or contact pins arranged asymmetrically with respect to the transverse axis. 3b shows an arrangement of three guide or contact pins 12, two of which lie on the longitudinal axis, but are arranged asymmetrically with respect to the transverse axis, the third guide or. Contact pin 12 is arranged on the transverse axis. 3c shows an arrangement with two guide or contact pins 12, one of which lies on the transverse and longitudinal axes.

Die voreilenden Führungs- bzw. Kontaktstifte 12 können einen gleichgeformten Querschnitt, beispielsweise einen kreisförmigen Querschnitt, aufweisen wie die Kontaktstif­ te 11. Die Führungs- bzw. Kontaktstifte 12 können aber auch durchgehend andersförmige Querschnitte aufweisen als die Kontaktstifte 11. Darüber hinaus können die voreilen­den Führungs- bzw. Kontaktstifte 12 unterschiedlich ge­formte Querschnitte, beispielsweise kreisförmige und rechtwinklige Querschnitte aufweisen. Diese Anordnungen sind in den FIG 3b und 3c dargestellt. Die asymmetrische Anordnung der Führungs- bzw. Kontaktstifte 12 sowie ihre unterschiedlichen Querschnittsformen schließen Fehler beim Zusammenstecken der mehrpoligen elektrischen Steck­verbindung aus.The leading guide or contact pins 12 can have a cross section of the same shape, for example a circular cross section, like the contact pin te 11. The guide or contact pins 12 can also have continuously different cross-sections than the contact pins 11. In addition, the leading guide or contact pins 12 can have differently shaped cross sections, for example circular and rectangular cross sections. These arrangements are shown in Figures 3b and 3c. The asymmetrical arrangement of the guide or contact pins 12 and their different cross-sectional shapes rule out errors when the multi-pole electrical plug connection is plugged together.
