Abstract

An electrical connector has an outer housing (1) and an inner housing (2). The outer unit is formed with internal guidance surfaces and a profiled toothed rack section (22). This is engaged by a lever (15) that also has a toothed profile (19, 20). The inner housing can only be inserted provided that it is correctly orientated and the lever is correctly positioned. Once inserted the lever can be moved to an interlocked position. <IMAGE>

Description

Die Erfindung betrifft ein Steckverbindergehäuse mit einem Außengehäuse und einem Innengehäuse, welche mit annähernd parallel gegenüberstehenden Seitenwänden schachtelförmig ineinander steckbar sind, wobei zumindest an einer Seite zwischen einer Innenwand des Außengehäuses und der gegenüberstehenden Außenwand des Innengehäuses ein Verriegelungsmechanismus in Form einer sich in Steckrichtung erstreckenden Zahnstange an der einen Wand und eines mit der Zahnstange kämmenden, mit einem Hebel fest verbundenen Zahnradsegmentes an der anderen Wand vorgesehen ist und wobei das Zahnradsegment um eine zur Einsteckrichtung senkrechte Achse drehbar an der Wand gelagert ist.The invention relates to a connector housing with an outer housing and an inner housing, which can be plugged into one another in a box-like manner with approximately parallel opposite side walls, with a locking mechanism in the form of a rack extending in the plug-in direction extending at least on one side between an inner wall of the outer housing and the opposite outer wall of the inner housing one wall and one meshing with the rack and firmly connected to a lever gear segment is provided on the other wall and wherein the gear segment is rotatably mounted on the wall about an axis perpendicular to the direction of insertion.

Ein derartig aufgebauter Steckverbinder ist grundsätzlich aus dem deutschen Gebrauchsmuster 87 14 016 bekannt. Mit Hilfe des an einem Hebel ausgebildeten Zahnradsegmentes in Verbindung mit der Zahnstange ist es möglich, auch an ungünstigen Montagestellen, beispielsweise in einem Kraftfahrzeug, die erforderlichen Steckkräfte aufzubringen und die beiden Gehäuseteile des Steckverbinders zuverlässig vollständig ineinanderzuschieben sowie in der Endstellung zu verriegeln. Da der Hebel aufgrund der konstruktiven Gegebenheiten nur über einen relativ geringen Winkelbereich geschwenkt werden kann und das Zahnradsegment dabei nur mit einem oder zwei Zähnen mit der Zahnstange in Eingriff gelangen kann, ist es wichtig, den zur Verfügung stehenden Schwenkbereich des Hebels auch voll auszunutzen. D. h., es muß sichergestellt werden, daß der Hebel bei Beginn der Steckbewegung vollständig in die Öffnungsstellung geschwenkt ist. Ist dies nicht der Fall, und kommt beispielsweise der Hebel mit dem Zahnradsegment bei einer undefinierten Zwischenstellung mit der Zahnstange in Eingriff, so reicht der verbleibende Schwenkbereich nicht mehr aus, um das Innengehäuse vollständig in das Außengehäuse zu stecken, so daß die Kontakte nicht oder nur unvollständig geschlossen werden. Weiterhin besteht die Gefahr, daß aus Unachtsamkeit die Gehäuseteile ineinandergesteckt werden, während der Hebel mit dem Zahnradsegment sich bereits in Schließstellung befindet. Hierbei kann es vorkommen, daß die Gehäuseteile unter Kraftaufwand teilweise ineinandergesteckt werden, wobei die Zähne des Zahnradsegmentes und der Zahnstange mehr oder weniger deformiert werden, eine ordnungsgemäße Kontaktgabe des Steckverbinders jedoch nicht erreicht wird.Such a connector is basically known from German utility model 87 14 016. With the help of the gear segment formed on a lever in connection with the rack, it is possible to apply the required insertion forces even at unfavorable assembly points, for example in a motor vehicle, and to reliably push the two housing parts of the connector into one another and lock them in the end position. As the lever can only be pivoted over a relatively small angular range due to the design conditions and the gear segment can only engage the rack with one or two teeth, it is important to fully utilize the available pivoting range of the lever. This means that it must be ensured that the lever is pivoted completely into the open position at the start of the plug-in movement. If this is not the case, and if, for example, the lever engages with the gear segment in an undefined intermediate position with the rack, then the remaining swivel range is no longer sufficient to completely insert the inner housing into the outer housing, so that the contacts are not closed or only incompletely. Furthermore, there is the risk that the housing parts are inserted into one another due to carelessness, while the lever with the gear segment is already in the closed position. It can happen that the housing parts are partially inserted into each other with force, whereby the teeth of the gear segment and the rack are more or less deformed, but proper contacting of the connector is not achieved.

Ziel der vorliegenden Erfindung ist es, bei einem Steckverbindergehäuse der eingangs genannten Art durch eine konstruktive Ausgestaltung der Verriegelungseinrichtung sicherzustellen, daß derartige Falschsteckungen oder eine Verriegelung in einer undefinierten Zwischenstellung vermieden werden.The aim of the present invention is to ensure in a connector housing of the type mentioned by constructive design of the locking device that such incorrect connections or locking in an undefined intermediate position are avoided.

Nach der Erfindung wird dieses Ziel bei einem derartigen Steckverbindergehäuse dadurch erreicht, daß die die Zahnstange tragende Gehäusewand im Randbereich der Einstecköffnung einerseits und das Zahnradsegment andererseits komplementäre Führungselemente aufweisen, welche nur bei einer vorgegebenen Winkelstellung des Zahnradsegmentes in Steckrichtung ineinanderpassen und erst nach einer vorgegebenen Einstecktiefe des Zahnradsegmentes dessen Drehung unter Eingriff in die Zahnstange freigeben.According to the invention, this object is achieved in such a connector housing in that the housing wall supporting the rack in the edge region of the insertion opening on the one hand and the gear segment on the other hand have complementary guide elements which only fit into one another in the insertion direction at a predetermined angular position of the gear segment and only after a predetermined insertion depth of Release the gear segment whose rotation engages in the rack.

Durch die erfindungsgemäß vorgesehenen zusätzlichen Führungselemente an den Randbereichen der beiden ineinanderzusteckenden Gehäuseteile wird also sichergestellt, daß das Einfädeln zu Beginn der Steckbewegung nur bei korrekter Öffnungsstellung des Hebels und damit des Zahnradsegmentes erfolgen kann.The additional guide elements provided according to the invention on the edge regions of the two housing parts to be inserted into one another thus ensure that threading at the beginning of the plug-in movement can only take place when the lever and thus the gearwheel segment are in the correct opening position.

Diese zusätzliche Führung kann bei einer vorteilhaften Ausgestaltung darin bestehen, daß die eine Gehäusewand in Verlängerung der Zahnstange eine Begrenzungsleiste bildet und daß das Zahnradsegment einen radial zurückgesetzten, zahnlosen Umfangsabschnitt aufweist, der in Öffnungsstellung des Hebels bzw. des Zahnradsegmentes mit der Begrenzungsleiste fluchtet. Das bedeutet, daß die Zähnung der Zahnstange nicht bereits am offenen Rand des betreffenden Gehäuses beginnt, sondern erst weiter innen, so daß das Zahnradsegment mit seinen mehr oder weniger in Steckrichtung ausgerichteten Zähnen erst an der Begrenzungsleiste vorbei nach innen geschoben werden muß, bis eine Drehung unter Eingriff in die Zahnstange möglich wird.In an advantageous embodiment, this additional guidance can consist in that the one housing wall in the extension of the rack forms a limiting strip and that the gear segment has a radially recessed, toothless peripheral section which is in the open position of the lever or the gear segment is aligned with the boundary bar. This means that the toothing of the rack does not start at the open edge of the housing in question, but only further inside, so that the gear segment with its teeth oriented more or less in the direction of insertion must first be pushed past the boundary strip inwards until it rotates by engaging the rack.

In einer anderen oder zusätzlichen Ausgestaltung ist weiterhin vorgesehen, daß das Zahnradsegment eine seine Dicke in Axialrichtung vergrößernde Längsrippe aufweist, welche bei Öffnungsstellung des Hebels in Einsteckrichtung verläuft und mit einer entsprechenden Nut in der die Zahnstange tragenden Wand fluchtet und daß sich die Nut nach der vorgegebenen Einstecktiefe erweitert, um ein Verdrehen der Rippe und des Zahnradsegmentes zu ermöglichen. Auch bei dieser zweiten Maßnahme wird also eine Ausrichtung des Hebels und des Zahnradsegmentes zu Beginn der Einsteckbewegung in der Öffnungsstellung des Hebels erzwungen. Da die Führungselemente bei falscher Stellung des Hebels bereits einen Anschlag erzeugen, bevor die beiden Gehäuseteile überhaupt ineinandergesteckt sind, ist diese Falschstellung für die Bedienperson sofort erkennbar, so daß diese auch nicht versuchen wird, die Gehäuseteile mit Kraftaufwand in einer Fehlstellung miteinander zu verriegeln.In another or additional embodiment it is further provided that the gear segment has a longitudinal rib which increases its thickness in the axial direction, which extends in the insertion direction when the lever is in the open position and is aligned with a corresponding groove in the wall carrying the toothed rack and that the groove is aligned according to the predetermined one Insertion depth extended to allow twisting of the rib and the gear segment. With this second measure, too, an alignment of the lever and the gear segment at the beginning of the insertion movement in the open position of the lever is forced. Since the guide elements already produce a stop when the lever is in the wrong position before the two housing parts are inserted into one another, this incorrect position is immediately recognizable for the operator, so that the operator will also not attempt to lock the housing parts with one another in an incorrect position using force.

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

The invention is explained in more detail below using exemplary embodiments with reference to the drawing. It shows
  • FIG. 1 shows a connector housing designed according to the invention with parts detached from one another in a perspective view,
  • Figures 2 to 5, a schematic compared to Figure 1 connector housing in a section through the locking device with different positions of the locking device and
  • 6 shows a connector housing according to the prior art corresponding to FIG. 5 in faulty locking.

Das Steckverbindergehäuse nach Figur 1 besteht im wesentlichen aus einem wannenförmigen Außengehäuse 1 und einem in dieses einsteckbaren Innengehäuse 2. Das Außengehäuse 1 besitzt einen im Querschnitt annähernd rechteckigen, durch Längsseitenwände 3, 4 und Querseitenwände 5, 6 begrenzten und an seinem inneren Ende durch einen Boden 7 abgeschlossenen Steckkanal 8 mit einer Vielzahl von aus dem Boden senkrecht emporstehenden, hier nicht sichtbaren Steckerstiften 9, die z. B. in zwei zueinander parallelen Reihen in einem bestimmten Raster angeordnet sind (siehe Figur 2). Das Innengehäuse 2 ist mit ebenfalls nicht sichtbaren Steckbuchsen für die Steckerstifte ausgestattet und besitzt einen im wesentlichen rechteckigen Querschnitt mit Längsseitenflächen 10, 11 und Querseitenflächen 12, 13 sowie eine Leitungszufuhrung 14.1 essentially consists of a trough-shaped outer housing 1 and an inner housing 2 which can be inserted therein. The outer housing 1 has an approximately rectangular cross section, delimited by longitudinal side walls 3, 4 and transverse side walls 5, 6 and at its inner end by a floor 7 closed plug-in channel 8 with a plurality of vertically rising from the floor, here not visible connector pins 9, the z. B. are arranged in two mutually parallel rows in a certain grid (see Figure 2). The inner housing 2 is equipped with likewise invisible sockets for the plug pins and has an essentially rectangular cross section with longitudinal side surfaces 10, 11 and transverse side surfaces 12, 13 and a line feed 14.

Zur Verbindung und zum Lösen des Außengehäuses 1 und des Innengehäuses 2 ist letzteres mit zwei Hebeln 15 (von denen nur einer sichtbar ist) ausgebildet, die über einen U-förmigen Bügel 16 verbunden sind und die jeweils an einem senkrecht von der jeweiligen Längsseitenfläche 10 bzw. 11 des Innengehäuses 2 abragenden Achsstummel 17 gelagert sind. Die an dem Achsstummel 17 gelagerten Enden der beiden Hebel 15 bilden jeweils ein zu dem Achsstummel 17 als Mittelachse ausgebildetes Zahnradsegment 18, von dem aber jeweils nur zwei Zähne 19 und 20 ausgebildet sind.To connect and detach the outer housing 1 and the inner housing 2, the latter is formed with two levers 15 (only one of which is visible), which are connected via a U-shaped bracket 16 and which are each connected to a vertical of the respective longitudinal side surface 10 or 11 of the inner housing 2 projecting stub axles 17 are mounted. The ends of the two levers 15 mounted on the stub axle 17 each form a gearwheel segment 18 which is designed as a central axis with the stub axle 17, but of which only two teeth 19 and 20 are formed.

Entsprechend den Zahnradsegmenten 18, die drehbar an der Außenwand 10 bzw. 11 des Innengehäuses 2 gelagert sind, besitzt das Außengehäuse 1 an den Innenseiten seiner Längsseitenwände 3 und 4 jeweils einen Zahnstangenansatz 21, der im vorliegenden Beispiel jeweils aus eineinhalb Zähnen, nämlich einer Zahnflanke 22 und einem voll ausgebildeten Zahn 23 besteht. Zur Verbindung der beiden Gehäuse 1 und 2 werden diese gemäß Figur 1 senkrecht ineinandergesteckt, wobei die beiden Hebel 15 und der Bügel 16 zu Beginn der Steckbewegung die in Figur 1 gezeigte Ruhestellung oder Öffnungsstellung einnehmen. Erst nach einer gewissen Einstecktiefe werden die beiden Hebel 15 entgegen dem Uhrzeigersinn verschwenkt, wobei die Zähne 19 und 20 mit der Zahnflanke 22 und dem Zahn 23 der Zahnstange 21 kämmen und dabei das Innengehäuse 2 vollständig in das Außengehäuse 1 ziehen, um so die Kontaktstifte 9 zuverlässig mit den entsprechenden Buchsen des Innengehäuses zu kontaktieren. Insoweit entsprechen der allgemeine Aufbau und die allgemeine Funktion auch dem Stand der Technik. Die Besonderheiten der Erfindung werden nun nachfolgend anhand der Figuren 2 bis 6 erläutert.Corresponding to the gearwheel segments 18, which are rotatably supported on the outer wall 10 and 11 of the inner housing 2, the outer housing 1 has on the inner sides of its longitudinal side walls 3 and 4 in each case a toothed rack attachment 21, which in the present example consists of one and a half teeth, namely a tooth flank 22 and a fully formed tooth 23. To connect the two housings 1 and 2, these are according to Figure 1 inserted vertically into each other, the two levers 15 and the bracket 16 at the beginning of the plug-in movement assume the rest position or open position shown in Figure 1. Only after a certain insertion depth are the two levers 15 pivoted counterclockwise, the teeth 19 and 20 meshing with the tooth flank 22 and the tooth 23 of the toothed rack 21 and thereby pulling the inner housing 2 completely into the outer housing 1, so that the contact pins 9 reliable contact with the corresponding sockets of the inner housing. In this respect, the general structure and the general function also correspond to the state of the art. The special features of the invention are now explained below with reference to FIGS. 2 to 6.

In den Figuren 2 bis 6 ist ein Schnitt durch eine Zahnstange 21 des Außengehäuses und einen Hebel 15 bzw. ein Zahnradsegment 18 des Innengehäuses in verschiedenen Positionen gezeigt, wobei der generelle Aufbau gegenüber Figur 1 vereinfacht und schematisiert wurde, um die grundsätzlichen Konstruktionselemente und Funktionen deutlicher zum Ausdruck zu bringen. Diese grundsätzlichen Funktionselemente sind jedoch mit den gleichen Bezugszeichen wie in Figur 1 versehen, da sie diesen in Gestaltung und Funktion entsprechen.2 to 6 show a section through a toothed rack 21 of the outer housing and a lever 15 or a gearwheel segment 18 of the inner housing in different positions, the general structure having been simplified and schematized compared to FIG. 1 in order to make the basic construction elements and functions clearer to express. However, these basic functional elements are provided with the same reference numerals as in FIG. 1, since they correspond to these in design and function.

Dabei sei zunächst auf Figur 6 verwiesen, welche einen schematischen Aufbau ohne die erfindungsgemäßen Merkmale zeigt. Hierbei ist die Zahnstange 21 bereits vom Rand des Steckkanals 8 her als Zahnstange ausgebildet, wobei anstelle der Zahnflanke 22 ein mehr oder weniger vollständig ausgebildeter Zahn 22a angeformt ist. Dadurch ist es möglich, daß der Hebel 15 mit dem Zahnradsegment 18, das in diesem Fall auch noch ansatzweise einen dritten Zahn 18a aufweist, auch bei einer Stellung in die Zahnstange 21 eingefädelt werden kann, die nicht der Öffnungsstellung entspricht, sondern beispielsweise eine Mittelstellung zwischen Öffnungs- und Schließstellung bildet. Der Zahn 19 kann dabei zwischen die Zähne 22a und 23 in Eingriff gelangen, während der Zahn 20 mit dem Beginn der Zahnstange nur eine geringe Durchdringung erfährt und bei relativ geringem Kraftaufwand auf den Hebel 15 sich leicht deformiert. Damit erreicht der Hebel 15 die in Figur 6 dargestellte Schließstellung, während das Zahnradsegment 18 mit seinen beiden Zähnen 19 und 20 nur mit dem Anfangsteil der Zahnstange 21 in Eingriff ist, so daß in der hier erreichten Endstellung die Kontaktstifte 9 nicht mit den entsprechenden Buchsen des Innengehäuses 2 kontaktieren. Diese Situation soll durch die Erfindung vermieden werden.Reference is first made to FIG. 6, which shows a schematic structure without the features according to the invention. Here, the toothed rack 21 is already designed as a toothed rack from the edge of the plug-in channel 8, a tooth 22a being formed more or less completely instead of the tooth flank 22. This makes it possible that the lever 15 with the gear segment 18, which in this case also has a third tooth 18a, can also be threaded into the rack 21 at a position which does not correspond to the open position but, for example, a middle position between Open and closed position forms. The tooth 19 can engage between the teeth 22a and 23, while the tooth 20 at the beginning of the Rack experiences only a small penetration and deforms slightly with relatively little effort on the lever 15. Thus, the lever 15 reaches the closed position shown in Figure 6, while the gear segment 18 with its two teeth 19 and 20 is only in engagement with the initial part of the rack 21, so that in the end position reached here, the contact pins 9 not with the corresponding sockets of the Contact inner housing 2. This situation is to be avoided by the invention.

Zur Vergrößerung der Sperrfläche bei falscher Stellung des Hebels 15 ist anstelle der zur Gehäuseöffnung weisenden Flanke des Zahnstangenzahnes 22a (Figur 6) in Verlängerung des Zahnscheitels eine Begrenzungsleiste 24 (siehe Figur 2) ausgebildet, welche bewirkt, daß die Zahnstange 21 erst nach der durch die Begrenzungsleiste 24 festgelegten Einstecktiefe mit der Zahnflanke 22 beginnt. Bei einer Stellung des Hebels 15 in Schließstellung gemäß Figur 2 oder in einer schrägen Zwischenstellung können die Zähne 19 und 20 nicht in den Steckkanal 8 eingeführt werden. Nur bei Öffnungsstellung des Hebels 15 gemäß Figur 4 ist das Zahnradsegment 18 in Richtung zur Zahnstange hin so schmal, daß ein Einstecken möglich ist; zu diesem Zweck ist auch der Zahnansatz 18a (Figur 6) an dem erfindungsgemäßen Zahnradsegment nicht mehr vorhanden.To enlarge the locking surface when the lever 15 is in the wrong position, a limiting strip 24 (see FIG. 2) is formed instead of the flank of the toothed rack tooth 22a (FIG. 6) in the extension of the tooth crown, which causes the toothed rack 21 to be lifted only after it has been moved through Boundary bar 24 defined insertion depth with the tooth flank 22 begins. When the lever 15 is in the closed position according to FIG. 2 or in an oblique intermediate position, the teeth 19 and 20 cannot be inserted into the plug-in channel 8. Only when the lever 15 is in the open position according to FIG. 4 is the gear segment 18 so narrow in the direction of the rack that an insertion is possible; for this purpose the tooth attachment 18a (FIG. 6) is no longer present on the gear segment according to the invention.

Eine weitere Sicherung gegen Einsteckung mit falscher Hebellage bildet die Kulisse oder Führungsrippe 25, die an dem Zahn 19 ausgebildet ist und die Dicke des Zahnradsegmentes in Axialrichtung vergrößert. Dieser Kulisse 25 entspricht eine Kulissenführung 26 in der Wand des Außengehäuses 1. Die Kulisse 25 stößt also am Rand des Steckkanals an, wenn der Hebel 15 in Schließstellung oder in einer schrägen Zwischenstellung gemäß Figur 3 steht. Das Innengehäuse 2 läßt sich nur in das Außengehäuse 1 einführen, wenn die Kulisse 25 in die Kulissenführung 26 eintaucht. Das ist nur bei der Öffnungsstellung gemäß Figur 4 möglich. Erst nach einer vorgegebenen Einstecktiefe erweitert sich die Kulissenführung 26 im Bereich 26a, wodurch eine Drehung des Zahnradsegmentes 18 und ein Eingriff der Zähne 19 und 20 an der Zahnflanke 22 und an dem Zahn 23 der Zahnstange 21 möglich werden. Dadurch wird das Innengehäuse vollständig unter Kontaktierung der Kontaktstifte 9 in das Außengehäuse 1 hineingezogen. Diesen Verriegelungszustand zeigt Figur 5.A further safeguard against insertion with the wrong lever position is provided by the link or guide rib 25, which is formed on the tooth 19 and increases the thickness of the gear segment in the axial direction. This link 25 corresponds to a link guide 26 in the wall of the outer housing 1. The link 25 therefore abuts the edge of the plug-in channel when the lever 15 is in the closed position or in an oblique intermediate position according to FIG. 3. The inner housing 2 can only be inserted into the outer housing 1 when the link 25 is immersed in the link guide 26. This is only possible in the open position according to FIG. 4. Only after a predetermined insertion depth, the link guide 26 expands Area 26a, whereby a rotation of the gear segment 18 and an engagement of the teeth 19 and 20 on the tooth flank 22 and on the tooth 23 of the rack 21 are possible. As a result, the inner housing is drawn completely into the outer housing 1 while contacting the contact pins 9. FIG. 5 shows this locked state.
