Abstract

The invention concerns a plug-in connector comprising a trough-shaped socket unit and a plug unit which fits into the socket unit, the ends of said connector each having safety ribs which together give the plug unit a width larger than the greatest internal diameter of the socket unit. This prevents the plug unit from being inserted crooked and hence damaging the pins located in the socket unit.

Description

Die Erfindung betrifft einen elektrischen Steckverbinder, bestehend aus einem wannenförmigen Aufnahmeteil und einem passend in diesen einsteckbaren Steckerteil, mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to an electrical connector, consisting of a trough-shaped receiving part and a plug part which can be plugged into it, with the features of the preamble of patent claim 1.

Ein derartiger Steckverbinder ist aus der US-A-4,376,565 bekannt.Such a connector is known from US-A-4,376,565.

Bei Vielfach-Steckverbindern ist es bekannt, im Steckergehause eine Codierung zur Sicherung gegen verkehrtes Einstecken vorzusehen. Zu diesem Zweck ist beispielsweise an dem einen Teil, etwa dem Steckerteil, eine Codierrippe angeformt, während eine komplementäre Codiernut in dem jeweils anderen Teil, also beispielsweise in dem Aufnahmeteil, vörgesehen ist. Der Steckerteil kann dann nur bei einer bestimmten Ausrichtung in den Aufnahmeteil eingeführt werden, vorausgesetzt, daß dieser eine entsprechende Codiernut besitzt.In the case of multiple plug connectors, it is known to provide coding in the plug housing to protect against incorrect insertion. For this purpose, for example, a coding rib is formed on one part, for example the plug part, while a complementary coding groove is provided in the other part, that is to say, for example, in the receiving part. The plug part can then only be inserted into the receiving part with a certain orientation, provided that the latter has a corresponding coding groove.

Eine solche Codierung verhindert jedoch nur, daß die beiden Steckerteile mit verkehrter Ausrichtung oder unterschiedlicher Codierung vollständig ineinander gesteckt werden und dabei fehlerhafte elektrische Verbindungen erzeugen. Die Codierung kann jedoch vielfach nicht verhindern, daß der Steckerteil teilweise in den Steckkanal eingeführt wird. Insbesondere kann es vorkommen, daß bei einer an einem Ende des Steckerteils angebrachten Codierrippe das andere Ende des Steckerteils schräg in den Steckkanal eingedrückt wird und dort die Steckerstifte beschädigt bzw. verbiegt. Dies ist beispielsweise denkbar bei der Montage an schwer zugänglichen und schlecht einsehbaren Stellen, etwa in Kraftfahrzeugen. Ein versehentlich schräges Einführen des Steckerteils in den Steckkanal kann dabei zu der erwähnten Beschädigung der Steckerstifte führen, was wiederum aufwendige Reparaturarbeiten durch Austausch der Teile zur Folge hat.However, such coding only prevents the two connector parts from being completely inserted into one another with the wrong orientation or different coding and thereby producing faulty electrical connections. In many cases, however, the coding cannot prevent the plug part from being partially inserted into the plug channel. In particular, it can happen that, when a coding rib is attached to one end of the plug part, the other end of the plug part is pressed obliquely into the plug-in channel and the plug pins are damaged or bent there. This is conceivable, for example, when installing in places that are difficult to access and difficult to see, for example in motor vehicles. An inadvertently oblique insertion of the plug part into the plug-in channel can lead to the aforementioned damage to the plug pins, which in turn results in expensive repair work by replacing the parts.

Aufgabe der vorliegenden Erfindung ist es deshalb, einen Steckverbinder der eingangs genannten Art so auszugestalten, daß ein versehentlich schräges Einstecken und damit eine Beschädigung der Steckerstifte zuverlässig ausgeschlossen wird.The object of the present invention is therefore to design a plug connector of the type mentioned at the outset in such a way that inadvertently oblique insertion and thus damage to the plug pins is reliably excluded.

Zur Lösung dieser Aufgabe ist bei einem Steckverbinder der eingangs genannten Art die Breite des Steckerteils mit den jeweils gegenüberliegenden Sicherheitsrippen größer als die größte lichte Weite des Steckkanals zwischen den Aussparungen.To solve this problem, the width of the connector part with the respective opposite safety ribs is greater than the greatest clear width of the plug-in channel between the cutouts in a connector of the type mentioned.

Wenn also erfindungsgemäß in den beiden Endbereichen der Längsseiten des Steckerteils jeweils überbreite Sicherheitsrippen vorgesehen sind, die die lichte Weite des Steckkanals in jedem seiner Bereiche überragen, so ist jegliches Falschstecken, auch ein schräges Einführen einer Endkante, ausgeschlossen.If, according to the invention, excess-wide safety ribs are provided in the two end regions of the long sides of the plug part, which protrude beyond the clear width of the plug-in channel in each of its regions, any incorrect insertion, including an oblique insertion of an end edge, is excluded.

Besondere Bedeutung hat die erfindungsgemäße Gestaltung für den Fall, daß der Steckkanal des Aufnahmeteils aufgrund von Aussparungen in den Längsseitenwänden etwa im mittleren Bereich eine vergrößerte lichte Weite aufweist. Dies ist beispielsweise bei dem Steckverbinder gemäß DE-GM 87 14 016 zu dem Zweck vorgesehen, in einem vergrößerten Spalt zwischen Steckerteil und Aufnahmeteil Organe zur Verriegelung der Steckverbindung anzuordnen. Wenn in einem solchen Fall also die Verriegelungsorgane an dem Steckerteil angebracht sind und der Steckkanal des Aufnahmeteils im Mittelbereich verhältnismäßig große Aussparungen besitzt, ist die Gefahr sehr groß, daß ein schräg eingeführter Steckerteil in diesem Mittelbereich des Steckkanals verhältnismäßig weit eingeführt werden kann und dort selbst in der Höhe zurückgesetzte Steckerstifte erreicht.The design according to the invention is of particular importance in the event that the plug-in channel of the receiving part has an enlarged internal width due to cutouts in the longitudinal side walls approximately in the central region. This is provided, for example, in the connector according to DE-GM 87 14 016 for the purpose of arranging organs for locking the plug connection in an enlarged gap between the plug part and the receiving part. If in such a case the locking members are attached to the plug part and the plug-in channel of the receiving part has relatively large recesses in the central area, the risk is very great that an obliquely inserted plug part can be inserted relatively far in this central area of the plug-in channel and even there the height of the reset pins is reached.

Sind die freien Enden der Steckerstifte, wie erwähnt, um einen bestimmten Sicherheitsabstand unterhalb des Abschlußrandes der Seitenwände des Aufnahmeteils angeordnet, so können die Sicherheitsrippen von der vorderen Abschlußfläche des Steckerteils um einen Abstand zurückgesetzt sein, der jedenfalls geringer ist als der Sicherheitsabstand der Steckerstifte. Durch dieses Zurücksetzen der Sicherheitsrippen wird erreicht, daß auch die entsprechenden Sicherheitsnuten in den Längsseitenflächen des Aufnahmeteils nur zu einem geringeren Maß in die Tiefe des Steckkanals geführt werden müssen. Die verhältnismäßig tiefen Sicherheitsnuten beeinträchtigen damit in geringerem Maße die Stabilität des Aufnahmeteils.If, as mentioned, the free ends of the plug pins are arranged a certain safety distance below the end edge of the side walls of the receiving part, the safety ribs can be set back from the front end face of the plug part by a distance which is in any case less than the safety distance of the plug pins. By resetting the safety ribs it is achieved that the corresponding safety grooves in the longitudinal side surfaces of the receiving part only have to be guided to a lesser extent into the depth of the plug-in channel. The relatively deep safety grooves thus impair the stability of the receiving part to a lesser extent.

Zweckmäßigerweise besitzen die Sicherheitsrippen einer Seitenfläche gegenüber den Endkanten der Seitenflächen jeweils einen unterschiedlichen Abstand. Damit erzielt man über die Sicherheitsrippen eine Art zusätzlicher Codierung gegen Falschpolung auch bei geradem Einstecken.The safety ribs of a side surface are expediently each at a different distance from the end edges of the side surfaces. This way, a kind of additional coding against incorrect polarity is achieved via the safety ribs, even when plugged in straight.

Natürlich können die Sicherheitsrippen zumindest zum Teil als Vorsprünge auf einer vorhandenen Codierrippe angeformt sein.Of course, the security ribs can at least partially be formed as projections on an existing coding rib.

Andererseits ist es auch möglich, einen Teil der Sicherreitsrippen an einer auf den Steckerteil aufgesteckten Verschlußplatte anzuformen.On the other hand, it is also possible to form part of the safety ribs on a closure plate which is plugged onto the plug part.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel anhand der Zeichnung näher erläutert. Es zeigt

  • Figur 1 bis 3 einen Steckerteil in drei verschiedenen Ansichten,
  • Figur 4 und 5 einen Aufnahmeteil in zwei verschiedenen Ansichten.
The invention is explained in more detail using an exemplary embodiment with reference to the drawing. It shows
  • 1 to 3 a plug part in three different views,
  • Figures 4 and 5 a receiving part in two different views.

Der in den Figuren 1 bis 3 gezeigte Steckerteil 1 besitzt ein Gehäuse 2, welches zumindest im unteren Teil 2a einen im wesentlichen rechteckigen Querschnitt besitzt. Dieser untere Teil ist am Außenumfang begrenzt von den Längsseiten 3 und 4 sowie von den Querseiten 5 und 6. Das in Steckrichtung vordere Ende ist begrenzt durch eine Abschlußfläche 7, welche eine Vielzahl von Stecköffnungen 8 (in Figur 2 sind nur einige davon angedeutet) besitzt. Im Inneren besitzt das Gehäuse einen Hohlraum 9, in welchen (in Figur 1 von links) Buchsenleisten eingeschoben werden können. Diese nicht dargestellten Buchsenleisten besitzen hinter jeder Stecköffnung 8 eine entsprechende Steckbuchse. Die Einführöffnung für die Buchsenleisten wird im vorliegenden Beispiel durch eine aufsteckbare Verschlußplatte 10 abgeschlossen. An der Oberseite des Steckerteils 1 ist außerdem ein Kabelzufuhrkanal 11 angeformt. Außerdem besitzt der Steckerteil an einem Ende eine an sich bekannte Codierrippe 12.The plug part 1 shown in FIGS. 1 to 3 has a housing 2 which has an essentially rectangular cross section, at least in the lower part 2a. This lower part is delimited on the outer circumference by the longitudinal sides 3 and 4 and by the transverse sides 5 and 6. The front end in the plugging direction is delimited by an end face 7 which has a plurality of plug openings 8 (in FIG. 2 are only some of them indicated). Inside, the housing has a cavity 9, into which (in FIG. 1 from the left) socket strips can be inserted. These socket strips, not shown, have a corresponding socket behind each plug opening 8. The insertion opening for the socket strips is closed in the present example by a plug-on closure plate 10. A cable feed channel 11 is also formed on the top of the plug part 1. In addition, the plug part has a coding rib 12 known per se at one end.

Der in den Figuren 4 und 5 gezeigte Aufnahmeteil 20 besitzt einen Gehäuseboden 21, welcher eine Vielzahl von Steckerstiften 22 aufweist, von denen in Figur 5 lediglich einige angedeutet sind. Die Höhe der Steckerstifte 22 ist in Figur4 durch die strichpunktierte Linie 22' angedeutet. Die Steckerstifte werden von einem umlaufenden Kragen des Aufnahmeteils umschlossen, der aus zwei Längsseitenwänden 23 und 24 sowie zwei Querseitenwänden 25 und 26 gebildet ist. Diese Seitenwände bilden somit einen Steckkanal 27, in welchen der Steckerteil 1 eingesteckt werden kann. Bei diesem Einsteckvorgang wird der Steckerteil mit seinen Querseitenflächen 5 und 6 an den Querseitenwänden 25 unc 26 und mit seinen Längsseitenflächen 3 und 4 an Führungsabschnitten 28, 29, 30 und 31 des Aufnahmeteils geführt.The receiving part 20 shown in FIGS. 4 and 5 has a housing base 21 which has a multiplicity of plug pins 22, only a few of which are indicated in FIG. 5. The height of the connector pins 22 is indicated in FIG. 4 by the dash-dotted line 22 '. The connector pins are enclosed by a circumferential collar of the receiving part, which is formed from two longitudinal side walls 23 and 24 and two transverse side walls 25 and 26. These side walls thus form a plug-in channel 27 into which the plug part 1 can be inserted. In this insertion process, the plug part is guided with its transverse side surfaces 5 and 6 on the transverse side walls 25 and 26 and with its longitudinal side surfaces 3 and 4 on guide sections 28, 29, 30 and 31 of the receiving part.

Entsprechend den Codierrippen 12 des Steckerteils sind in dem Aufnahmeteil Codiernuten 32 vorgesehen, so daß auch bei senkrechtem Einstecken und bei richtiger Ausrichtung nur der zugehörige Steckerteil in den Aufnahmeteil eingeführt werden kann.Corresponding to the coding ribs 12 of the plug part, coding grooves 32 are provided in the receiving part, so that even when inserted vertically and with correct alignment, only the associated plug part can be inserted into the receiving part.

Da sich die Codierrippe in dem gezeigten Beispiel nur an der im Bild rechten Seite befindet, verhindert sie nicht ein fehlerhaftes Einführen des Steckerteils in Schrägstellung, also mit der im Bild linken Endkante voraus. Dabei können, obwohl der Steckerteil natürlich nicht voll eingesteckt werden kann, trotzdem die Steckerstifte 22 beschädigt werden. Dies gilt für das gezeigte Beispiel umso mehr, als in dem Aufnahmeteil in den Längsseitenwänden 23 und 24 jeweils zwischen den Führungsabschnitten 28 und 30 bzw. 29 und 31 Aussparungen 33 und 34 vorgesehen sind, welche für eine nicht dargestellte Verriegelungsvorrichtung zwischen Aufnahmeteil und Steckerteil Platz schaffen. In diesem Fall könnte der Steckerteil sogar mit den Codierrippen 12 voraus schräg eingeführt werden.Since the coding rib in the example shown is only on the right side in the picture, it does not prevent the plug part from being inserted incorrectly in the inclined position, that is to say with the end edge on the left in the picture. Here, although the connector part can of course not be fully inserted, the connector pins 22 can still be damaged. This applies even more to the example shown, since recesses 33 and 34 are provided in the receiving part in the longitudinal side walls 23 and 24 between the guide sections 28 and 30 or 29 and 31, respectively, which create space for a locking device (not shown) between the receiving part and the plug part . In this case, the connector part could even be inserted obliquely with the coding ribs 12 ahead.

Um ein derartiges schräges Einstecken zu verhindern, sind in den Endbereichen der Längsseitenflächen 3 und 4 des Steckerteils jeweils beiderseits zusätzliche Sicherheitsrippen 35, 36, 37 und 38 angeformt, durch die der Steckerteil an den Enden jeweils eine Breite erhält, die in jedem Fall größer ist als die größte lichte Weite des Steckkanals 27 zwischen den Aussparungen 33 und 34. Den genannten Sicherheitsrippen 35, 36, 37 und 38 sind im Aufnahmeteil entsprechende Sicherheitsnuten 45, 46, 47 und 48 komplementär zugeordnet. Wie aus Figur 1 ersichtlich ist, besitzen diese Sicherheitsrippen 35 und 36 an dem einen Ende des Steckerteils und die Sicherheitsrippen 37 und 38 am anderen Ende des Steckerteils jeweils einen unterschiedlichen geringen Abstand von der jeweiligen Endkante bzw. den Querseitenflächen 5 bzw. 6. Sie bieten somit auch die Gewähr, daß der Steckerteil nicht um 180° verdreht in senkrechter Richtung eingesteckt werden kann.In order to prevent such an oblique insertion, additional safety ribs 35, 36, 37 and 38 are formed on both sides in the end regions of the longitudinal side surfaces 3 and 4 of the plug part, through which the plug part is given a width at the ends, which is larger in each case than the greatest clear width of the plug-in channel 27 between the cutouts 33 and 34. The safety ribs 35, 36, 37 and 38 mentioned are correspondingly assigned corresponding safety grooves 45, 46, 47 and 48 in the receiving part. As can be seen from FIG. 1, these safety ribs 35 and 36 at one end of the plug part and the safety ribs 37 and 38 at the other end of the plug part each have a different small distance from the respective end edge or the transverse side faces 5 and 6, respectively thus also the guarantee that the connector part cannot be inserted rotated by 180 ° in the vertical direction.

Da die zusätzlichen Sicherheitsnuten 45, 46, 47 und 48 in ihrem Bereich die Wandstärke des Aufnahmeteils verringern, ist es erwünscht, diese Nuten nicht zu tief zu machen. Aus diesem Grund sind im vorliegenden Beispiel die Sicherheitsrippen 35 bis 38 nicht bis zurAbschlußfläche 7 geführt, sondern um einen bestimmten Abstand zurückgesetzt, so daß auch die Sicherheitsnuten 45 bis 48 nicht sehr tief zu sein brauchen. Dieser Abstand der zurückgesetzten Sicherheitsrippen darf jedoch nicht größer sein als der Abstand der oberen Enden der Stekkerstifte 22, wie er durch die strichpunktierte Linie 22' in Figur 4 angedeutet ist, vom oberen Rand 39 der Seitenwände 23 und 24. Damit kann der Steckerteil zwar bis zu einergewissen Tiefe auch schräg eingeführt werden jedoch dabei die Steckerstifte 22 nicht gefährden.Since the additional safety grooves 45, 46, 47 and 48 reduce the wall thickness of the receiving part in their area, it is desirable not to make these grooves too deep. For this reason, in the present example, the safety ribs 35 to 38 are not led to the end face 7, but are set back by a certain distance, so that the safety grooves 45 to 48 do not need to be very deep either. However, this distance between the recessed safety ribs must not be greater than the distance between the upper ends of the plug pins 22, as indicated by the dash-dotted line 22 'in FIG. 4, from the upper edge 39 of the side walls 23 and 24. This means that the connector part can be up to to a certain depth also inserted obliquely, however, the connector pins 22 are not at risk.
