Description

Die Erfindung betrifft eine Steckverbinderanordnung, umfassend zwei ineinander steckbare Steckverbinderteile nach der Gattung des Anspruchs 1.The invention relates to a connector assembly comprising two plug-in connector parts according to the preamble of claim 1.

Stand der TechnikState of the art

Solche Steckverbinderanordnungen existieren in unterschiedlichen Ausgestaltungen. Aus der EP 2 302 745 A1 ist beispielsweise ein elektrischer Steckverbinder bekannt geworden mit zwei ineinander steckbaren Steckverbinderteilen, die beide jeweils aneinander angepasste Gehäuseteile und in diesen aneinander angepasste Steckkontakte aufweisen. Die beiden Steckverbinderteile weisen Rastelemente zur lösbaren Verbindung der beiden Gehäuseteile auf, wobei das eine Rastelement eine Zunge mit einer Rastnase ist, welche über den Steckkontakten angeordnet ist. Die Steckkontakte selbst weisen jeweils an ihrer der Zunge zugewandten Seite Stege auf, die ein Eindringen von Schutz in die Steckkontakte verhindern. Die Zunge überragt auch diese Stege und kann so aufgrund ihrer exponierten Lage Beschädigungen, beispielsweise durch Herausbiegen, ausgesetzt sein.Such connector assemblies exist in different configurations. From the EP 2 302 745 A1 For example, an electrical connector has become known with two plug-in connector parts which can be plugged into one another and which each have housing parts adapted to one another and plug contacts adapted to one another. The two connector parts have locking elements for releasably connecting the two housing parts, wherein the one locking element is a tongue with a latching nose, which is arranged over the plug contacts. The plug contacts themselves each have on their side facing the tongue webs, which prevent penetration of protection in the plug contacts. The tongue also projects beyond these webs and can be so exposed due to their exposed position damage, for example by bending out.

Die US 5,203,719 offenbart eine Steckverbinderanordnung, bei der ebenfalls eine Zunge mit einem Rastelement vorgesehen ist, das in ein entsprechendes, an sie angepasstes Gegenelement eines zweiten Steckverbinderteils eingreift. Bei dieser Steckverbinderanordnung ist die Zunge zwar innerhalb zweier sie umschließender U-förmiger Schenkel angeordnet, das Rastelement überragt diese U-förmigen Schenkel jedoch, sodass hier rein prinzipiell durch die exponierte Lage des Rastelements ebenfalls eine Beschädigung der Rastverbindung möglich ist. Insbesondere ist die Zunge zusammen mit dem Rastelement im ineinandergesteckten Zustand weiterhin von außen zugänglich. Das birgt die Gefahr in sich, dass beispielsweise ein unbeabsichtigtes Entrasten der Rastverbindungselemente durch Druck auf die Zunge von außerhalb erfolgen kann.The US 5,203,719 discloses a connector assembly in which a tongue is also provided with a latching element which is in a corresponding, adapted to it counter-element of a second connector part engages. In this connector assembly, the tongue is indeed arranged within two enclosing U-shaped legs, but the locking element projects beyond these U-shaped legs, so that in principle here by the exposed position of the locking element also damage the locking connection is possible. In particular, the tongue is still accessible from the outside together with the latching element in the nested state. This entails the danger that, for example, unintentional unlatching of the latching connection elements can take place by pressure on the tongue from outside.

Aus der DE 10 2004 054 203 A1 geht eine Schneidklemm-Steckkontaktleiste für elektrische Steckverbinder hervor, mit kombinierten Anschlusselementen, die an einem Ende einen Schneidklemmbereich für einen abisolierfreien Anschluss elektrischer Leiter und am anderen Ende einen Steckkontaktbereich für eine Steckkontakt-Gegenleiste ausbilden, wobei der Schneidklemmbereich flache, geschlitzte Schneidklemmen trägt. Die Anschlusselemente sind so gestaltet, dass zu einer Reihe nebeneinander eingebetteter Steckkontakte der Anschlusselemente die Schneidklemmen dieser Anschlusselemente mehrreihig in der Schneidklemm-Steckleiste liegen. Die beiden Steckverbinderteile werden mittels einer federnd ausgebildeten Raste, die im verrasteten Zustand der beiden Steckverbinderteile in einen Rastschlitz eingreift, aneinander verrastet. Die Raste ist bei dieser Steckverbinderanordnung an der Gehäuseoberseite weitestgehend freiliegend angeordnet.From the DE 10 2004 054 203 A1 shows an insulation displacement plug connector for electrical connectors, with combined connection elements, which form at one end an insulation displacement for a stripping electrical conductor and at the other end a plug contact region for a plug contact counter strip, the insulation displacement area carries flat, slotted insulation displacement terminals. The connection elements are designed such that the insulation displacement terminals of these connection elements lie in a multi-row fashion in the insulation displacement plug-in connector for a series of plug-in contacts of the connection elements embedded next to one another. The two connector parts are latched to each other by means of a spring-shaped catch, which engages in the latched state of the two connector parts in a locking slot. The catch is arranged largely exposed in this connector assembly on the housing top.

Aus der DE 20 2011 000 739 U1 ist eine Steckverbindungsanordnung für elektrische Leiter bekannt geworden mit einem Stecker mit mindestens einem Tunnel, einer Buchse mit mindestens einer Rastzunge, wobei die mindestens eine Rastzunge mit dem mindestens einen Tunnel des Steckers für eine verrastende Zusammenwirkung in einem zusammengesteckten Zustand der Steckverbindungsanordnung vorgesehen ist, und mit mindestens einem an dem Stecker angebrachten Deckabschnitt, der einen Schutz der mindestens einen Rastzunge im Zustand der verrastenden Zusammenwirkung gegen manuelle Einwirkung sowie Betätigung durch ein Werkzeug bildet. Bei dieser Steckverbindungsanordnung ist die Zunge im verrasteten Zustand weitestgehend geschützt, da sie in dem für sie vorgesehenen Tunnel liegt. Im unverrasteten Zustand steht die Zunge jedoch frei von der Buchse ab und ist so leicht Beschädigungen ausgesetzt.From the DE 20 2011 000 739 U1 a connector assembly for electrical conductors has become known with a plug having at least one tunnel, a socket with at least one latching tongue, wherein the at least one latching tongue is provided with the at least one tunnel of the plug for a latching interaction in a mated state of the connector assembly, and with at least one attached to the plug cover portion, a protection of at least forms a latching tongue in the state of latching interaction against manual action and actuation by a tool. In this connector assembly, the tongue is largely protected in the locked state, since it lies in the tunnel provided for them. In the unlatched state, however, the tongue is free from the socket and is easily exposed to damage.

Aus der DE 10 2008 051 589 A1 ist ein Kuppler und ein Stecker einer Steckverbindung mit Koshiri-Sicherheit bekannt geworden, bei dem das Kupplergehäuse eine abstehende Federlasche aufweist, die im Bereich ihres freien Endes einen Absatz aufweist. Das Kupplergehäuse und die Federlasche bilden ein einstückiges Bauteil. Die Federlasche greift in eine entsprechende an sie angepasste Öffnung des entsprechenden weiteren Steckverbinderteils ein. Auch in diesem Fall steht die Federlasche - wenngleich auch einstückig mit dem Kupplergehäuse ausgebildet - von dem Kupplergehäuse ab und kann insoweit bei ungünstiger Handhabung beschädigt werden.From the DE 10 2008 051 589 A1 is a coupler and a plug of a connector with Koshiri security has become known in which the coupler housing has a protruding spring tab having a paragraph in the region of its free end. The coupler housing and the spring tab form a one-piece component. The spring tab engages in a corresponding adapted to it opening of the corresponding further connector part. Also in this case, the spring tab is - although also integrally formed with the coupler housing - from the coupler housing and can be damaged in this respect in unfavorable handling.

Offenbarung der ErfindungDisclosure of the invention Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Steckverbinderanordnung hat demgegenüber den Vorteil, dass die Rastelemente wenigstens eine in einer Zungenaufnahmetasche in dem ersten Gehäuseteil angeordnete Rastzunge mit einer Rastnase umfassen, wobei die Rastnase in eine für sie vorgesehene Öffnung in einer Gehäusewand des zweiten Gehäuseteils eingreift und dass die Zungenaufnahmetasche in dem ersten Gehäuseteil nutförmig mit im Wesentlichen U-förmigem Querschnitt ausgebildet ist, wobei die beiden seitlichen U-Schenkel die Rastzunge überragen. Dieses Überragen der beiden seitlichen U-Schenkel ermöglicht einen besonders wirkungsvollen Schutz der Rastzunge, denn die zwischen den beiden U-Schenkeln liegende Rastzunge kann nicht ohne Weiteres beispielsweise "herausgebogen" werden. In dem zweiten Gehäuseteil sind Führungsnuten für die beiden U-Schenkel vorgesehen. Gleichzeitig begrenzen die Führungsnuten die Zungenaufnahmetasche in dem zweiten Steckverbinderteil und bilden so zusammen mit den beiden U-Schenkeln und den U-förmigen Nuten im gesteckten Zustand der beiden Steckverbinderteile die Zungenaufnahmetasche, in der die Rastzunge im ineinandergesteckten Zustand der beiden Steckverbinderteile zu liegen kommt.The connector assembly according to the invention has the advantage that the locking elements comprise at least one arranged in a tongue receiving pocket in the first housing part latching tongue with a detent, wherein the detent engages in an opening provided for it in a housing wall of the second housing part and that the tongue receiving pocket in the first Housing part is groove-shaped with a substantially U-shaped cross-section, wherein the two lateral U-legs project beyond the latching tongue. This projection of the two lateral U-legs allows a particularly effective protection of the latching tongue, because the catch tongue lying between the two U-legs can not be "bent out" without further notice. In the second housing part are Guiding grooves provided for the two U-legs. At the same time limit the guide grooves the tongue receiving pocket in the second connector part and thus form together with the two U-legs and the U-shaped grooves in the inserted state of the two connector parts, the tongue receiving pocket in which the latching tongue comes to rest in the nested state of the two connector parts.

Vorteilhafte Weiterbildungen und Verbesserungen der im unabhängigen Anspruch angegebenen Steckverbinderanordnung sind Gegenstand der abhängigen Ansprüche. So reichen bevorzugt und besonders vorteilhaft die beiden U-Schenkel steckseitig bis an die Stirnseite des einen Gehäuseteils. Diese Anordnung ermöglicht besonders vorteilhaft eine Koshiri-Sicherheit. Die beiden U-Schenkel, die bis an die Stirnseite des Steckers reichen und die die zwischen ihnen angeordnete Rastzunge seitlich überragen, schützen nämlich nicht nur die Rastzunge im unverrasteten Zustand der Steckverbinderanordnung, sondern sie verhindern auch sehr wirkungsvoll eine Fehlsteckung oder ein verkantetes Einstecken der beiden Steckverbinderteile, was zu einer Beschädigung der in ihnen angeordneten Kontaktelemente führen könnte.Advantageous developments and improvements of the independent claim specified connector assembly are the subject of the dependent claims. So rich preferably and particularly advantageous the two U-legs plug side to the front side of a housing part. This arrangement is particularly advantageous for Koshiri security. The two U-legs, which extend to the front side of the plug and laterally project beyond the locking tongue arranged between them, namely not only protect the latching tongue in the unlocked state of the connector assembly, but they also very effectively prevent mis-insertion or tilted insertion of the two Connector parts, which could lead to damage of the contact elements arranged in them.

Auch diese Führungsnuten reichen sehr vorteilhaft bis an die Stirnseite des zweiten Gehäuseteils. Diese beiden bis an die Stirnseite des zweiten Gehäuseteils reichenden Führungsnuten stellen gewissermaßen den Gegenpart der beiden U-Schenkel dar, was die Koshiri-Sicherheit angeht. Auch sie verhindern nicht nur eine Fehlsteckung, sondern insbesondere auch eine verkantete Steckung, die zur Beschädigung der Kontaktelemente führen könnte.These guide grooves extend very advantageous up to the front side of the second housing part. These two reaching to the front side of the second housing part guide grooves are effectively the counterpart of the two U-legs, which concerns the Koshiri security. They also prevent not only a mishap, but in particular a jammed connection, which could lead to damage of the contact elements.

Die beiden Nutstege zusammen mit der gegenüber den Nutstegen etwas zurückversetzten Fläche sowie die beiden U-Schenkel und die im Wesentlichen parallel zur Rastzunge verlaufende Fläche bilden im ineinandergesteckten Zustand der beiden Steckverbinderteile die Zungenaufnahmetasche, in der die Rastzunge vollständig geschützt angeordnet ist.The two Nutstege together with the opposite to the Nutstegen slightly recessed surface and the two U-legs and extending substantially parallel to the locking tongue surface form in the nested state of the two connector parts, the tongue receiving pocket in which the latching tongue is arranged completely protected.

Die Rastzunge ist vorteilhafterweise federnd ausgebildet und sie ist vorteilhafterweise einstückig mit einem der beiden Gehäuseteile ausgebildet.The latching tongue is advantageously resilient and it is advantageously formed integrally with one of the two housing parts.

Die an ihr angeordnete Rastnase weist vorteilhafterweise steckseitig eine Abschrägung auf, die ein Hineingleiten der Rastnase in die dafür vorgesehene Öffnung in dem zweiten Gehäuseteil erleichtert.The locking lug arranged on it advantageously has on the plug side a chamfer, which facilitates a sliding in of the latching lug into the opening provided in the second housing part.

Eine in Fig. 1, Fig. 2 und Fig. 3 dargestellte Steckverbinderanordnung umfasst zwei Steckverbinderteile 100, 200. Der eine Steckverbinderteil 100 kann beispielsweise als Federleiste ausgebildet sein, wohingegen der andere Steckverbinderteil 200 - wie dargestellt - als Messerleiste ausgebildet ist. Hierzu sind in dem als Federleiste ausgebildeten Steckverbinderteil 100 in einem Steckteil 102 des Gehäuses 101 Federkontaktelemente 110 vorgesehen. In dem als Messerleiste ausgebildeten Steckverbinderteil 200 sind dagegen in einem entsprechenden Gehäuseteil 202 des Gehäuses 201 Messerkontaktelemente 210 angeordnet. Die Messerkontaktelemente 210 sind in entsprechend angepasste Federkontaktelemente 110 des Steckverbinderteils 100 steckbar.An in Fig. 1 . Fig. 2 and Fig. 3 The connector assembly 100 shown may be formed for example as a female connector, whereas the other connector part 200 - as shown - is designed as a male connector. For this purpose, spring contact elements 110 are provided in the male connector part 100 designed as a spring connector in a plug-in part 102 of the housing 101. In the plug connector part 200 designed as a male connector, however, knife contact elements 210 are arranged in a corresponding housing part 202 of the housing 201. The blade contact elements 210 can be plugged into correspondingly adapted spring contact elements 110 of the connector part 100.

Im Wesentlichen oberhalb und parallel verlaufend zu den Federkontaktelementen 110 des ersten Steckverbinderteils 100 ist eine Rastzunge 300, nachfolgend auch kurz als Zunge bezeichnet, angeordnet, die eine Rastnase 310 aufweist. Die Rastnase 310 weist in Steckrichtung eine Abschrägung 312 auf, die ein Hineinschieben in eine in dem Gehäuse 201 des zweiten Steckverbinderteils 200 angeordnete an die Rastzunge 300 angepasste Öffnung 400 erleichtert. Die Rastzunge 300 ist federnd ausgebildet, so dass sie sich beim Einschieben in das Gehäuse 201 des zweiten Steckverbinderteils 200 geringfügig in Richtung der Federkontaktelemente 110 verbiegt, was durch die als Gleitfläche wirkende Abschrägung 312 erleichtert wird, bis die Rastnase 310 vollständig hinter der Öffnung 400 liegt und mit ihrem Rastende 313 an einer die Öffnung 400 aufnehmenden Gehäusewand 222 anliegt. In diesem Falle sind die beiden Steckverbinderteile miteinander verrastet und ein Auseinanderziehen ist nur möglich, indem die Zunge wiederum in Richtung der Federkontaktelemente 110, beispielsweise mittels eines entsprechenden Werkzeugs, gebogen wird.In essence, above and parallel to the spring contact elements 110 of the first connector part 100, a latching tongue 300, hereinafter also referred to as tongue for short, is arranged, which has a latching nose 310. The locking lug 310 has a chamfer 312 in the insertion direction, which facilitates insertion into a opening 400 arranged in the housing 201 of the second connector part 200 and adapted to the latching tongue 300. The latching tongue 300 is resiliently formed, so that it bends slightly when inserted into the housing 201 of the second connector part 200 in the direction of the spring contact elements 110, which is facilitated by acting as a sliding surface chamfer 312 until the latch 310 is completely behind the opening 400 and rests with its detent end 313 at a housing wall receiving the opening 400 222. In this case, the two connector parts are locked together and a pulling apart is only possible by the tongue in turn in the direction of the spring contact elements 110, for example by means of a corresponding tool, is bent.

Die Zunge 300 liegt in einer entsprechenden Aufnahmetasche 500, die eine im Wesentlichen U-förmige Gestalt aufweist mit einer Fläche 501, die im Wesentlichen parallel zur Zunge 300 verläuft und mit seitlichen U-Schenkeln 510, 520. Die U-Schenkel 510, 520 überragen die Zunge 300, d.h. die Zunge 300 liegt vollständig, insbesondere auch hinsichtlich ihrer Höhe, in dem von den U-Schenkeln 510, 520 und der Fläche 501 gebildeten U-förmigen Bereich der auf diese Weise ausgebildeten gewissermaßen ersten Hälfte der Zungenaufnahmetasche 500 (Fig. 1).The tongue 300 lies in a corresponding receiving pocket 500, which has a substantially U-shaped configuration with a surface 501 which extends substantially parallel to the tongue 300 and with lateral U-legs 510, 520. The U-legs 510, 520 project beyond the tongue 300, ie the tongue 300 lies completely, in particular in terms of their height, in the U-shaped region formed by the U-legs 510, 520 and the surface 501 of the thus formed in a sense first half of the tongue receiving pocket 500 (FIGS. Fig. 1 ).

Der zweite Steckverbinderteil 200 (Fig. 2) weist Führungsnuten 610, 620 auf, die der Führung der beiden U-förmigen Schenkel 510, 520 dienen. Auf diese Weise ist ein sehr präzises und verpolungssicheres Ineinanderstecken der beiden Steckverbinderteile möglich.The second connector part 200 ( Fig. 2 ) has guide grooves 610, 620 which serve to guide the two U-shaped legs 510, 520. In this way, a very precise and reverse polarity nesting of the two connector parts is possible.

Im ineinandergesteckten Zustand der beiden Steckverbinderteile 100, 200 liegt die Zunge 300 innerhalb der beiden Gehäuseteile, wobei die Zungenaufnahmetasche 500 gebildet wird durch den U-förmigen Bereich des ersten Steckverbinderteils 100 und die beiden Führungsnuten 610, 620 des zweiten Steckverbinderteils 200 in Verbindung mit einer gegenüber zwei Nutstegen 611, 621 etwas zurückversetzten Fläche 601 (Fig. 2). Die beiden Nutstege 611, 621 zusammen mit der Fläche 601 sowie die beiden U-Schenkel 510, 520 und die Fläche 501 bilden im ineinandergesteckten Zustand der beiden Steckverbinderteile 100, 200 die Zungenaufnahmetasche 500, in der die Rastzunge 300 vollständig geschützt angeordnet ist.In the nested state of the two connector parts 100, 200, the tongue 300 is within the two housing parts, wherein the tongue receiving pocket 500 is formed by the U-shaped portion of the first connector part 100 and the two guide grooves 610, 620 of the second connector part 200 in conjunction with one opposite two groove webs 611, 621 slightly recessed surface 601 (FIG. Fig. 2 ). The two Nutstege 611, 621 together with the surface 601 and the two U-legs 510, 520 and the surface 501 form in the nested state of the two connector parts 100, 200, the tongue receiving pocket 500, in which the latching tongue 300 is arranged completely protected.

Die beiden U-förmigen Schenkel 510, 520 in Verbindung mit den beiden Nuten 610, 620 und den entsprechenden Nutschenkeln 611, 621 erfüllen aber gleichzeitig noch eine andere sehr wesentliche Aufgabe, die nachstehend noch näher erläutert wird.The two U-shaped legs 510, 520 in conjunction with the two grooves 610, 620 and the corresponding groove legs 611, 621 but at the same time fulfill another very important task, which will be explained in more detail below.

Sowohl die beiden U-Schenkel 510, 520 als auch die beiden Nutschenkel 611, 621 reichen bis an die Stirnseite der entsprechenden Gehäuseteile der beiden Steckverbinderteile 100, 200. Sie sind verhältnismäßig massiv ausgebildet und verhindern nicht nur eine Fehlsteckung aufgrund ihrer Ausgestaltung. Sie verhindern insbesondere auch ein verkantetes Ineinanderstecken der beiden Steckverbinderteile 100, 200, sie dienen mit anderen Worten auch der Ausbildung der sogenannten Koshiri-Sicherheit. Diese Koshiri-Sicherheit wird nicht nur mit den jeweils bis an die Stirnseiten der Steckverbinderteile reichenden U-Schenkeln 510, 520 und den Nutschenkeln 611, 621 erreicht, sondern auch damit, dass die Kontaktelemente 110 bzw. 210 gegenüber der Stirnseite der beiden Steckverbinderteile 100, 200 zurückversetzt sind und insbesondere gegenüber den beiden U-Schenkeln 510, 520 und den beiden Nutschenkeln 611, 621 zurückversetzt sind. Durch dieses zurückversetzte Anordnen der Steckkontakte in Verbindung mit den massiven U-förmigen Schenkeln 510, 520 und den die Nuten 610, 620 bildenden Nutschenkeln 611, 621, die jeweils beide bis an die Stirnseite des Gehäuses der Steckverbinderteile 100, 200 reichen, wird ein verkantetes Stecken, das zu einer Beschädigung der Kontaktelemente führen kann, wirkungsvoll verhindert. Gleichzeitig wird unter Ausbildung eines synergistischen Effektes durch die Anordnung und das Zusammenwirken der U-förmigen Schenkel 510, 520 und der Nuten 610, 620 in Verbindung mit der Fläche 501 sowie der zurückversetzten Fläche 601 eine Zungenaufnahmetasche 500 gebildet, die die Zunge 300 nicht nur im verrasteten Zustand, sondern insbesondere auch im unverrasteten Zustand der beiden Steckverbinderteile 100, 200 aneinander wirkungsvoll schützt.Both the U-legs 510, 520 and the two groove legs 611, 621 extend to the end face of the corresponding housing parts of the two connector parts 100, 200. They are relatively solid and prevent not only a misfire due to their design. They also prevent in particular a tilted nesting of the two connector parts 100, 200, they serve in other words, the training of so-called Koshiri security. This Koshiri safety is achieved not only with the respectively reaching to the front sides of the connector parts U-legs 510, 520 and the groove legs 611, 621, but also so that the contact elements 110 and 210 relative to the front side of the two connector parts 100, 200 are set back and in particular with respect to the two U-legs 510, 520 and the two groove legs 611, 621 are set back. By this recessed arrangement of the plug contacts in conjunction with the solid U-shaped legs 510, 520 and the grooves 610, 620 forming groove legs 611, 621, each of which extends to the front side of the housing of the connector parts 100, 200, a tilted Plug, which can lead to damage of the contact elements, effectively prevented. At the same time, forming a synergistic effect by the arrangement and the cooperation of the U-shaped legs 510, 520 and the grooves 610, 620 in conjunction with the surface 501 and the recessed surface 601 a tongue receiving pocket 500 is formed, which not only the tongue 300 in the Locked state, but especially in the unlocked state of the two connector parts 100, 200 effectively protects each other.

Die U-förmigen Schenkel 510, 520 zusammen mit der Fläche 501 sowie die Nuten 610, 620 zusammen mit den Nutschenkeln 611, 621 und der zurückversetzten Fläche 601 ermöglichen also nicht nur die Ausbildung einer Zungenaufnahmetasche 500, sondern sie stellen gleichzeitig auch die Koshiri-Sicherheit des Steckers sicher.The U-shaped legs 510, 520 together with the surface 501 and the grooves 610, 620 together with the groove legs 611, 621 and the recessed surface 601 thus not only allow the formation of a tongue receiving pocket 500, but they also provide the Koshiri security the plug sure.

Abschließend ist zu bemerken, dass die in Fig. 1 bis Fig. 3 dargestellte Steckverbindungsanordnung einen Steckverbindungsteil 200 umfasst, der beispielsweise auf einer Leiterplatte angeordnet wird und dort kontaktiert wird mit entsprechend vorgesehenen Leiterbahnen, und einen Steckverbindungsteil 100, der beispielsweise mit entsprechenden elektrischen Leitern mittels an sich bekannter Schneidklemmkontaktierungen kontaktiert wird. Hierzu sind Öffnungen 170 vorgesehen, in die beispielsweise ein Flachbandkabel hineinragt oder auch einzelne Drähte, die in dem Steckverbinderteil 100 beispielsweise auf die in der DE 10 2004 054 203 A1 beschriebene Weise mittels Schneidklemmen kontaktiert werden.Finally, it should be noted that the in Fig. 1 to Fig. 3 Connector assembly shown comprises a connector part 200 which is arranged for example on a printed circuit board and contacted there with correspondingly provided conductor tracks, and a connector part 100 which is contacted for example with corresponding electrical conductors by means of known insulation displacement contacts. For this purpose, openings 170 are provided into which projects, for example, a ribbon cable or individual wires that in the connector part 100, for example, in the in the DE 10 2004 054 203 A1 described manner be contacted by insulation displacement terminals.
