Description

Die Erfindung betrifft ein Kontaktelement für Steckverbinder mit steckseitig angeordneten Steckkontakten und einem kabelseitig angeordneten Crimpanschluss nach dem Oberbegriff des Anspruchs 1. Ferner betrifft die Erfindung einen Steckverbinder mit wenigstens einem solchen, in einem Steckverbindergehäuse angeordneten Kontaktelement nach dem Oberbegriff des Anspruchs 6.The invention relates to a contact element for plug-in connectors with plug contacts arranged on the plug side and a crimp connection arranged on the cable side. The invention further relates to a plug connector having at least one contact element arranged in a plug connector housing according to the preamble of claim 6.

Stand der TechnikState of the art

Ein gattungsgemäßer Steckverbinder geht aus der DE 20 2010 011 545 U1 hervor. Dieser Steckverbinder weist Kontaktelemente mit kabelanschlussseitig angeordneten Crimpanschlüssen auf, die jeweils mit einem Primärverriegelungselement und einem Sekundärverriegelungselement versehen sind. Jedes Kontaktelement dient als Federkontakt und ist darüber hinaus dazu vorgesehen, ein einzelnes Kabel durch Crimpen zu kontaktieren und in dem Kontaktelement zu fixieren. Jedes dieser Kontaktelemente wird in einem Steckverbindergehäuse angeordnet, wobei die Kontaktelemente nebeneinander liegen. Derartige Steckverbinder werden beispielsweise im Automobilbau eingesetzt. Sie dienen der Kontaktierung von einzelnen Kabeln in einem Steckverbinder mit mehreren nebeneinander oder auch übereinander liegenden Kontaktelementen. Die Kontaktierung von einzelnen Kabeln in einem gemeinsamen Steckverbinder ist im Automobilbau notwendig, da an verschiedenen Stellen Ausleitungen von einzelnen Kabeln aus einem gemeinsamen Kabelbaum erforderlich sind.A generic connector goes out of the DE 20 2010 011 545 U1 out. This connector has contact elements with crimp terminals arranged on the cable side, which are each provided with a primary locking element and a secondary locking element. Each contact element serves as a spring contact and is also intended to contact a single cable by crimping and to fix in the contact element. Each of these contact elements is arranged in a connector housing, wherein the contact elements are adjacent. Such connectors are used for example in the automotive industry. They are used to contact individual cables in a connector with several adjacent or superimposed contact elements. The contacting of individual cables in a common connector is necessary in the automotive industry, since at various points discharges of individual cables from a common wiring harness are required.

EP 1 077 513 A1 und US 2002/146943 A1 zeigen Steckkontakte mit den Merkmalen des Oberbegriffs des Anspruchs 1. EP 1 077 513 A1 and US 2002/146943 A1 show plug contacts with the features of the preamble of claim 1.

Gerade im Automobilbau sind solche Steckverbinder hohen Belastungen, beispielsweise Rüttelbelastungen und dergleichen, ausgesetzt. Diesen Belastungen halten Crimpverbindungen sehr gut stand. Aufgrund des Bauraums, welchen Crimpanschlüsse einnehmen, ist es jedoch nicht ohne Weiteres möglich, diese Stecker sehr kompakt zu bauen. Der Abstand der Kontaktelemente im Steckverbindergehäuse ist im Wesentlichen durch die Maße/Durchmesser der Crimpanschlüsse bestimmt.Especially in automotive such connectors are exposed to high loads, such as Rüttelbelastungen and the like. Crimp connections withstand these loads very well. Due to the space, which take crimp connections, but it is not readily possible to build these connectors very compact. The spacing of the contact elements in the connector housing is essentially determined by the dimensions / diameter of the crimp terminals.

Offenbarung der ErfindungDisclosure of the invention

Die erfindungsgemäßen Kontaktelemente mit den Merkmalen des Anspruchs 1 und der erfindungsgemäße Steckverbinder, bei welchem in einem Steckverbindergehäuse derartige Kontaktelemente angeordnet sind, mit den Merkmalen des Anspruchs 6 ermöglichen demgegenüber auf sehr vorteilhafte Weise einen sehr kompakten Aufbau und eine weitere Miniaturisierung derartiger Steckverbinder und damit eine Erhöhung der Anzahl der in einem solchen Steckverbinder anzuordnenden Kontaktelemente und damit eine Erhöhung der Anzahl der zu kontaktierenden Kabel, die in den Steckverbinder münden. Außerdem wird erst hierdurch eine zweireihige Ausführung eines solchen Stecksystems möglich.The contact elements according to the invention with the features of claim 1 and the connector according to the invention, in which such contact elements are arranged in a connector housing, with the features of claim 6 allow in contrast to a very advantageous manner, a very compact design and further miniaturization of such connectors and thus an increase the number of contact elements to be arranged in such a connector and thus an increase in the number of cables to be contacted, which open into the connector. In addition, only a double-row version of such a plug-in system is possible.

Erfindungsgemäß ist hierzu vorgesehen, dass die Steckkontakte und der Crimpanschluss achsparallel versetzt zueinander sind und dass das wenigstens eine Primärverriegelungselement zwei quer zur Steckrichtung federnde und zu einer Steckmittelebene spiegelsymmetrisch angeordnete Verriegelungsfedern und dass das wenigstens eine Sekundärverriegelungselement wenigstens eine quer zur Steckrichtung und zu der Steckmittelebene spiegelsymmetrisch in dem Kontaktelement angeordnete Sekundärverriegelungsaufnehmung aufweisen. Durch das Zusammenwirken durch die achsparallel versetzte Anordnung von Steckkontakt und Crimpanschluss und der spiegelsymmetrisch zur Steckmittelebene angeordneten Primärverriegelungselemente und Sekundärverriegelungselemente ist es möglich, die Steckkontakte in dem Steckverbinder um jeweils 180° gedreht zueinander nebeneinander zu positionieren. Hierdurch ist eine zweireihige Anordnung der Steckkontakte in einem Steckverbinder möglich. In diesem Falle sind die Steckkontakte in einer Ebene und zwei derartige Ebenen von nebeneinander liegenden Steckkontakten liegen übereinander. Die Steckkontakte und damit die Crimpanschlüsse sind in der einen Ebene relativ zur anderen Ebene um 180° gedreht.According to the invention, it is provided for this purpose that the plug contacts and the crimp connection are offset from one another in an axially parallel manner and that the at least one primary locking element has two locking springs that are resilient transversely to the plug-in direction and mirror-symmetrically arranged to a plug center plane Secondary locking element have at least one transversely to the direction of insertion and to the insertion center plane mirror symmetrically arranged in the contact element Sekundärverriegelungsaufnehmung. Due to the interaction of the axially parallel offset arrangement of plug contact and crimp and the mirror symmetry arranged to the plane of insertion plane primary locking elements and secondary locking elements, it is possible to position the plug contacts in the connector rotated by 180 ° to each other side by side. As a result, a double-row arrangement of the plug contacts in a connector is possible. In this case, the plug contacts are in one plane and two such levels of juxtaposed plug contacts are one above the other. The plug contacts and thus the crimp terminals are rotated in one plane relative to the other plane by 180 °.

Gemäß einer vorteilhaften Ausgestaltung eines erfindungsgemäßen Steckverbinders ist vorgesehen, dass die Steckkontakte in dem Steckverbinder jeweils alternierend um 180° gedreht zueinander nebeneinander positioniert sind, wobei die jeweils übereinander und untereinander liegenden Crimpanschlüsse im montierten Zustand quer (senkrecht) zur Steckrichtung überlappen können. Dies ermöglicht es, die Steckkontakte in einer Reihe anzuordnen, wobei die Steckkontakte wesentlich dichter nebeneinander liegen können als bei aus dem Stand der Technik bekannten Steckern, denn die Crimpanschlüsse "stören sich" gewissermaßen aufgrund ihrer alternierenden Anordnung in dem Steckverbindergehäuse nicht mehr "gegenseitig", denn sie liegen jeweils versetzt zueinander und können so dicht nebeneinander liegen, dass die Crimpanschlüsse in verschiedenen Ebenen geringfügig überlappen. Durch diese Anordnung ist es auch erst möglich, solche Stecksysteme in zweireihiger Ausführung auszubilden. Dies wird durch die Möglichkeit, Steckverbinder in um 180° gedrehten Positionen zu montieren, ermöglicht. Weitere vorteilhafte Weiterbildungen und Ausgestaltungen des erfindungsgemäßen Kontaktelements und des erfindungsgemäßen Steckverbinders sind Gegenstand der auf die Ansprüche 1 und 6 jeweils rückbezogenen Unteransprüche.According to an advantageous embodiment of a connector according to the invention it is provided that the plug contacts are alternately positioned in the connector rotated 180 ° to each other next to each other, each of which one above the other and crimping crimps in the assembled state can overlap transversely (perpendicular) to the direction of insertion. This makes it possible to arrange the plug contacts in a row, wherein the plug contacts can be much closer together than in the prior art known plugs, because the crimp terminals "disturb themselves" to some extent due to their alternating arrangement in the connector housing no longer "mutually", because they are offset from each other and can be so close to each other that the crimp terminals overlap slightly in different levels. By this arrangement, it is only possible to form such connector systems in two-row design. This is made possible by the ability to mount connectors in positions rotated through 180 °. Further advantageous developments and refinements of the contact element according to the invention and of the connector according to the invention are the subject of the dependent claims to the claims 1 and 6, respectively.

So ist vorteilhafterweise vorgesehen, dass die Steckkontakte und der Crimpanschluss um ein Längenmaß zueinander versetzt sind, das im Wesentlichen wenigstens der größten Abmessung senkrecht zur Steckrichtung bzw. dem Durchmesser des Crimpanschlusses entspricht. Auf diese Weise ist sehr vorteilhaft die vorstehend beschriebene leicht überlappende Anordnung der in Ebenen versetzt zueinander angeordneten Kontaktelemente möglich.Thus, it is advantageously provided that the plug contacts and the crimp connection are offset by a length dimension to each other, which corresponds substantially to at least the largest dimension perpendicular to the insertion direction or the diameter of the crimp. In this way, the above-described slightly overlapping arrangement of the contact elements arranged in planes offset from one another is very advantageously possible.

Sehr vorteilhaft weist auch jedes Kontaktelement kabelanschlussseitig auf den Crimpanschluss folgend ein Crimp-Arretierelement auf, welches nach der Montage des Kontaktelements im Steckverbindergehäuse unter Ausübung einer Vorspannung in einer zu ihm gegengleichen Ausnehmung in dem Steckverbindergehäuse zur Anlage kommt. Auf diese Weise wird das Kontaktelement im Steckverbindergehäuse fixiert und dadurch erreicht, dass auch erhebliche Rüttelbelastungen, wie sie beispielsweise in Fahrzeugen auftreten können, nicht zu einem Bruch beispielsweise des Übergangsbereichs zwischen den Kontaktelementen und dem Crimpbereich oder zu einer Kontaktkorrosion eines Kupferleiters in dem Crimpanschluss, die isolierend wirkt, führen.Very advantageously also has each contact element cable connection side on the crimp following a crimp-locking on which comes after installation of the contact element in the connector housing while exerting a bias in a counter to him recess in the connector housing to the plant. In this way, the contact element is fixed in the connector housing and thereby achieved that even significant vibration loads, such as may occur in vehicles, not to break, for example, the transition region between the contact elements and the crimp or contact corrosion of a copper conductor in the crimp, the insulating effect, lead.

Sehr vorteilhaft ist dabei vorgesehen, dass das Crimp-Arretierelement am unteren Rand des Crimpanschlusses angeordnet ist. Am unteren Rand bedeutet dabei im Wesentlichen in der Ebene geöffneter Crimpflügel liegend.Very advantageous is provided that the crimp-locking element is arranged at the bottom of the crimp. At the bottom of this means essentially lying in the plane open Crimflügel.

Die als Federkontakte ausgebildeten Steckkontakte sind an einem steckkontaktseitig angeordneten U-Bügel angeordnet, sie verjüngen sich nach innen, sind federnd ausgebildet und weisen in Richtung der Kabelanschlussseite. Diese Ausbildung dient einer einfachen und wirkungsvollen Aufnahme von Messerkontaktelementen, und zwar in der Weise, dass gleichzeitig auch eine Betätigung der Primärverriegelung auf die nachfolgend noch näher zu beschreibende Weise realisiert wird.The plug contacts formed as spring contacts are arranged on a plug contact side arranged U-bracket, they taper inwards, are resilient and point in the direction of Cable connection side. This training serves a simple and effective recording of blade contact elements, in such a way that at the same time an actuation of the primary lock is realized in the manner to be described in more detail below.

Die Verriegelungsfedern weisen auf ihrer der Steckmittelebene zugewandten Seite vorzugsweise Messerkontakt-Auflageflächen auf. Diese dienen dazu, ein Ausrasten der Verriegelungsfedern aus den in dem Steckverbindergehäuse vorgesehenen Öffnungen wirkungsvoll zu verhindern, denn die Messerkontakt-Auflageflächen liegen an den Messerkontaktelementen an und erlauben keine Bewegung der Verriegelungsfedern in Richtung der Steckmittelebene im gesteckten Zustand der Messerkontaktelemente.The locking springs preferably have blade contact bearing surfaces on their side facing the plug center plane. These serve to effectively prevent disengagement of the locking springs from the openings provided in the connector housing, because the blade contact bearing surfaces abut against the blade contact elements and do not allow movement of the locking springs in the direction of the plug center plane in the inserted state of the blade contact elements.

Die in dem Gehäuse vorgesehenen Sekundärverriegelungsnocken weisen in Bezug auf die Sekundärverriegelungsausnehmungen vorzugsweise ein Übermaß auf, sodass bei einem Eingreifen der Verriegelungsnocken in die Sekundärverriegelungsausnehmungen ein Festklemmen der Verriegelungsnocken in den Sekundärverriegelungsausnehmungen hervorgerufen wird. Durch einen vollständigen Eingriff der Nocken in die Sekundärverriegelungsausnehmungen wird das Kontaktelement in dem Steckverbindergehäuse gesichert.The secondary interlocking cams provided in the housing are preferably oversized with respect to the secondary interlocking recesses such that upon engagement of the interlocking cams with the secondary interlocking recesses, the locking cams in the secondary interlocking recesses become jammed. By a complete engagement of the cams in the Sekundärverriegelungsausnehmungen the contact element is secured in the connector housing.

Diese steckseitig angeordneten Steckkontakte 112 dienen der Aufnahme eines Messerkontaktelements 310 (siehe Fig. 6).A contact element 100 as a whole has a contact region 110, a locking region 120 and a crimping region 130. The contact region 110 consists essentially of a U-shaped bent bracket 111, on which in the insertion direction R inwardly tapering, resiliently formed and in the direction of the cable end side, ie the crimping 130, facing plug contacts 112 are arranged. These plug-in contacts 112 arranged on the plug serve to receive a blade contact element 310 (see FIG Fig. 6 ).

Der sich an den Kontaktbereich 110 anschließende Verriegelungsbereich 120 weist Primärverriegelungselemente und Sekundärverriegelungselemente auf. Die Primärverriegelungselemente sind zwei quer zur Steckrichtung R federnde und zu einer Steckmittelebene E, die sich in der Mitte zwischen den Steckkontakten 112 senkrecht von einem Steckgrundteil des Bügels 113 erstreckt, spiegelsymmetrisch angeordnete Verriegelungsfedern 122, die in entsprechende Ausnehmungen 260 in einem Steckverbindergehäuse im montierten Zustand eingreifen und dort durch ihre Federwirkung gehalten werden (siehe Fig. 1, Fig. 5).The locking area 120 adjoining the contact area 110 has primary locking elements and secondary locking elements. The primary locking elements are two transversely to the direction of insertion R resilient and to a plug center plane E, which extends in the middle between the plug contacts 112 perpendicularly from a plug-in base of the bracket 113, mirror-symmetrically arranged locking springs 122 which engage in corresponding recesses 260 in a connector housing in the assembled state and held there by their spring action (see Fig. 1 . Fig. 5 ).

Diese Verriegelungsfedern 122 bilden die Primärverriegelung. An diese schließt sich auf der dem Crimpbereich 130 zugewandten Seite des Verriegelungsbereichs 120 eine Sekundärverriegelung an, die unter anderem durch Sekundärverriegelungsausnehmungen 124 gebildet wird. Auch diese Sekundärverriegelungsausnehmungen 124 sind spiegelsymmetrisch zur Ebene E angeordnet.These locking springs 122 form the primary lock. This is followed on the side of the locking region 120 facing the crimping region by a secondary locking, which is formed, inter alia, by secondary locking recesses 124. These Sekundärverriegelungsausnehmungen 124 are arranged mirror-symmetrically to the plane E.

Durch die spiegelsymmetrische Anordnung sowohl der Verriegelungsfedern 122 des Primärverriegelungselements als auch der Sekundärverriegelungsausnehmungen 124 des Sekundärverriegelungselements ist es möglich, das Kontaktelement ohne bauliche Veränderungen auch um 180° gedreht zu verwenden. In diesem Falle vertauschen die obere und untere Verriegelungsfeder 122 und die oberen und unteren Sekundärverriegelungsausnehmungen 124 ihre Positionen. Der U-Bügel 111 wird ebenfalls um 180° gedreht, sodass die Grundfläche 113 in Steckrichtung R betrachtet in Fig. 1 statt auf der rechten auf der linken Seite angeordnet ist. Die Steckkontakte 112 sind ebenfalls spiegelsymmetrisch zur Ebene E ausgebildet und angeordnet, sodass eine Steckung in beiden um 180° gedrehten Positionen des Kontaktelements 100 möglich ist. In beiden jeweils um 180° gedrehten Positionen des Kontaktelements 100 ist auch die volle Funktion des Primärverriegelungselements und des Sekundärverriegelungselements gewährleistet. Neben dieser spiegelsymmetrischen Anordnung sowohl der Steckkontakte 112, der Verriegelungsfedern 122 des Primärverriegelungselements und der Sekundärverriegelungsausnehmungen 124 des Sekundärverriegelungselements ist vorgesehen, dass der Crimpbereich 130 zum Verriegelungsbereich 120 und Kontaktbereich 110 achsparallel um einen Abstand A versetzt ist. Dieser Abstand A entspricht im Wesentlichen wenigstens dem Durchmesser D bzw. dem größten Maß senkrecht zur Steckrichtung eines Crimpanschlusses im vercrimpten Zustand (vergl. Fig. 3, Fig. 4). Der Crimpanschluss weist auf an sich bekannte Weise Crimpflügel 132 zur Vercrimpung von Litzen und Klemmflügel 134 zum Klemmen des Isolationsmantels eines (nicht gezeigten) Kabels zur Zugentlastung auf. An die Klemmflügel 134 schließt sich ein Crimp-Arretierelement 136 an, welches im Wesentlichen eine T-förmige Gestalt aufweist und in der Ebene der vollständig flach gebogenen Crimpflügel 132 bzw. Klemmflügel 134 liegt. Die Funktion dieses Arretierelements 136 wird nachfolgend noch näher beschrieben.Due to the mirror-symmetrical arrangement of both the locking springs 122 of the primary locking element and the Sekundärverriegelungsausnehmungen 124 of the secondary locking element, it is possible to use the contact element without structural changes rotated by 180 °. In this case, the upper and lower locking springs 122 and the upper and lower secondary locking recesses 124 reverse their positions. The U-bracket 111 is also rotated by 180 °, so that the base 113 viewed in the direction of insertion R in Fig. 1 instead of being arranged on the right on the left side. The plug contacts 112 are also formed and arranged mirror-symmetrically to the plane E, so that a connection in both rotated by 180 ° positions of the contact element 100 is possible. In both rotated by 180 ° positions of the contact element 100, the full function of the primary locking element and the secondary locking element is ensured. In addition to this mirror-symmetrical arrangement of both the plug contacts 112, the locking springs 122 of the primary locking element and the Sekundärverriegelungsausnehmungen 124 of the secondary locking element is provided that the crimping region 130 is offset to the locking portion 120 and contact portion 110 parallel to the axis by a distance A. This distance A corresponds essentially to at least the diameter D or the largest dimension perpendicular to the plug-in direction of a crimp terminal in the crimped state (see FIG. Fig. 3 . Fig. 4 ). The crimp connection has a known manner Crimping prong 132 for crimping strands and clamping wings 134 for clamping the insulation jacket of a cable (not shown) for strain relief. Adjoining the clamping wings 134 is a crimp-locking element 136, which has a substantially T-shaped form and lies in the plane of the completely flat curved crimping blade 132 or clamping wing 134. The function of this locking element 136 will be described in more detail below.

Derartige Kontaktelemente werden in einem Steckverbinder, der als Ganzer mit 200 bezeichnet ist, angeordnet. Hierzu sind in einem Steckverbindergehäuse 210 an die Kontaktelemente 100 angepasste Öffnungen 230 vorgesehen, die der Aufnahme und Positionierung der Kontaktelemente 100 dienen (siehe Fig. 3 - 6). Die Kontaktelemente 100 werden hierzu von einer Stirnseite des Gehäuses 210 in die Öffnungen 230 hineingeschoben und aufgrund der Verriegelungselemente dort fixiert, wie nachfolgend in Verbindung mit Fig. 5 und Fig. 6 noch näher erläutert wird. Erfindungsgemäß ist nun vorgesehen, dass die Ausnehmungen 230 in dem Steckverbindergehäuse 210 so angeordnet sind, dass die Kontaktelemente 100 alternierend um jeweils 180° gedreht zueinander nebeneinander liegend positioniert sind. Wie Fig. 3 zeigt, ermöglicht eine solche Ausbildung die Anordnung sehr dicht nebeneinander liegender Kontaktbereiche 110 in einer Reihe. Dies wird dadurch ermöglicht, dass die Crimpbereiche 130 nicht nebeneinander, sondern abwechselnd in einer alternierenden Weise übereinander liegen, wobei die Crimpbereiche 130 aufgrund der übereinander liegenden Anordnung überlappen können und so eine dichte Anordnung der Kontaktbereiche 110 erst ermöglichen. Hierdurch ist es auch möglich, Steckverbinder mit einer zweireihigen Ausführung der Kontaktelemente zu realisieren. In diesem Falle liegen die Kontaktelemente übereinander, wobei die Kontaktelemente 100 in übereinanderliegenden Reihen jeweils um 180° zueinander gedreht angeordnet sind. Um eine solche alternierende Anordnung der Kontaktelemente realisieren zu können, müssen die Verriegelungselemente, also Primärverriegelungs- und Sekundärverriegelungselemente, spiegelsymmetrisch zur Ebene E ausgebildet sein, um ein einziges Kontaktelement in zwei unterschiedlichen, um 180° zueinander gedrehten Positionen in dem Steckverbindergehäuse 210 anordnen zu können.Such contact elements are arranged in a connector, which is designated as a whole by 200. For this purpose, in a connector housing 210 to the contact elements 100 adapted openings 230 are provided which serve to receive and positioning of the contact elements 100 (see Fig. 3 - 6 ). For this purpose, the contact elements 100 are pushed into the openings 230 from an end face of the housing 210 and fixed there due to the locking elements, as described below in connection with FIG Fig. 5 and Fig. 6 will be explained in more detail. According to the invention it is now provided that the recesses 230 are arranged in the connector housing 210 so that the contact elements 100 are positioned alternately rotated by 180 ° to each other lying side by side. As Fig. 3 shows, such a design allows the arrangement of very close-lying contact areas 110 in a row. This is made possible by the fact that the crimping regions 130 do not lie next to one another but alternately one above the other in an alternating manner, wherein the crimping regions 130 may overlap due to the superimposed arrangement and thus allow a tight arrangement of the contact regions 110. As a result, it is also possible to realize connectors with a double-row version of the contact elements. In this case, the contact elements are superimposed, wherein the contact elements 100 are arranged in superimposed rows each rotated by 180 ° to each other. In order to realize such an alternating arrangement of the contact elements, the locking elements, ie primary locking and Secondary locking elements, mirror-symmetrical to the plane E be formed in order to arrange a single contact element in two different, rotated by 180 ° to each other positions in the connector housing 210 can.

Fig. 5 zeigt den Moment des Einschiebens eines Kontaktelements 100 in das Steckverbindergehäuse 200. Die Kontaktbereiche 110 mit jeweils den beiden Steckkontakten 112, die sich in Steckrichtung R verjüngen und federnd ausgebildet sind, werden bis zu einer Öffnung 270 des Gehäuses 200 geschoben. Erst im vollständig eingeschobenen Zustand federt eine der beiden Verriegelungsfedern 122 des Primärverriegelungselements in eine im Gehäuse dafür vorgesehene Öffnung 260 ein. Das benachbarte Kontaktelement ist um 180° gedreht und bei diesem federt die andere Verriegelungsfeder 122 in die Öffnung 260 ein. Bei benachbarten Kontaktelementen 100 greifen also jeweils in Bezug auf die Ebene E abwechselnd die obere bzw. untere Verriegelungsfeder 122 des Primärverriegelungselements in die Öffnung 260 ein. Fig. 5 shows the moment of insertion of a contact element 100 in the connector housing 200. The contact portions 110 with each of the two plug contacts 112, which are tapered in the insertion direction R and resilient, are pushed up to an opening 270 of the housing 200. Only in the fully inserted state does one of the two locking springs 122 of the primary locking element spring into an opening 260 provided in the housing for this purpose. The adjacent contact element is rotated by 180 ° and in this the other locking spring 122 springs into the opening 260 a. In the case of adjacent contact elements 100, the upper or lower locking spring 122 of the primary locking element therefore alternately engage in the opening 260 with respect to the plane E in each case.

Fig. 6 zeigt den Steckverbinder 200 mit montiertem Kontaktelement 100 in Zusammenwirkung mit einem weiteren passenden Steckverbinder 300 in isometrischer Schnittdarstellung. Der weitere Steckverbinder 300 weist Messerkontakte 310 auf, von denen in Fig. 6 nur ein einziger Kontakt zu sehen ist. Der Messerkontakt 310 greift in die Steckkontakte 112 unter Herstellung eines elektrischen Kontakts ein. Gleichzeitig ragt er so tief in den Verriegelungsbereich 120, dass die das Primärverriegelungselement bildenden und quer zur Steckrichtung R verlaufenden Verriegelungsfedern 122 in einer Öffnung 260 des Steckverbindergehäuses 210 eine Rastposition fixieren. Fig. 6 shows the connector 200 with mounted contact element 100 in cooperation with another mating connector 300 in isometric cross-sectional view. The further connector 300 has blade contacts 310, of which in Fig. 6 only a single contact can be seen. The blade contact 310 engages the plug contacts 112 to make an electrical contact. At the same time, it protrudes so deeply into the locking region 120 that the locking springs 122 forming the primary locking element and extending transversely to the plug-in direction R fix a latching position in an opening 260 of the plug connector housing 210.

Nachdem ein Messerkontaktelement oder Messerkontakt 310 in das Federkontaktelement 100 eingeschoben wurde, wie es schematisch in Fig. 6 dargestellt ist, wird wirkungsvoll und sicher verhindert, dass ein Ausrasten der Verriegelungsfedern 122, das heißt ein Ausrasten des Rasthakens der Verriegelungsfedern 122 aus den entsprechenden Öffnungen 260 des Steckverbindergehäuses 210 stattfinden kann. In diesem Falle liegen nämlich die Verriegelungsfedern 122 mit ihren dem Messerkontakt 310 zugewandten Auflageflächen 123 auf den Messerkontakten 310 auf, sodass im gesteckten Zustand ein Ausrasten der Verriegelungsfedern 122 ausgeschlossen ist.After a knife contact element or blade contact 310 has been inserted into the spring contact element 100, as shown schematically in FIG Fig. 6 is shown effectively and safely prevents disengagement of the Locking springs 122, that is, a disengagement of the latching hook of the locking springs 122 can take place from the corresponding openings 260 of the connector housing 210. In this case, namely the locking springs 122 with their knife contact 310 facing support surfaces 123 on the blade contacts 310, so that in the mated state disengagement of the locking springs 122 is excluded.

Es ist ein weiteres Sekundärverriegelungselement 340 in Form von Sekundärverriegelungsnocken 342 vorgesehen, welche in die Sekundärverriegelungsausnehmungen 124 eingreifen. Auch hier gilt, dass die Kontaktelemente 100 aufgrund der spiegelsymmetrischen Anordnung der Sekundärverriegelungsausnehmungen 124 in Bezug auf die Ebene E in zwei unterschiedlichen, um 180° gedrehten Positionen alternierend angeordnet werden können, wobei ein und dasselbe Sekundärverriegelungselement 340 mit den Sekundärverriegelungsnocken 342 einmal in die einen (oberen) Sekundärverriegelungsausnehmungen 124 und das andere Mal in die anderen (unteren) Sekundärverriegelungsausnehmungen 124, die spiegelsymmetrisch zur Ebene E angeordnet sind, eingreifen. Die Sekundärverriegelungsnocken 342 weisen gegenüber den Sekundärverriegelungsausnehmen 124 ein geringes Übermaß auf. Hierdurch wird eine vorgespannte Fixierung des Kontaktelements 100 in dem Steckverbindergehäuse 200 im gesteckten Zustand ermöglicht.There is another secondary locking element 340 in the form of secondary locking cams 342 which engage the secondary locking recesses 124. Again, because of the mirror-symmetrical arrangement of the secondary locking recesses 124 relative to the plane E, the contact elements 100 can be alternately arranged in two different positions rotated through 180 °, one and the same secondary locking element 340 with the secondary locking cams 342 being inserted once into one ( upper) secondary locking recesses 124 and the other time into the other (lower) secondary locking recesses 124, which are arranged mirror-symmetrically to the plane E, engage. The secondary locking cams 342 have a slight excess over the secondary locking recesses 124. As a result, a prestressed fixation of the contact element 100 in the connector housing 200 is enabled in the inserted state.

Wie aus Fig. 4 und Fig. 6 hervorgeht, sind für das Crimp-Arretierelement 136 in dem Gehäuse 200 Ausnehmungen 236 vorgesehen, die an das Crimp-Arretierelement 136 angepasst sind und zwar so, dass durch die Anordnung des am unteren Rand des Crimpanschlusses angeordneten Crimp-Arretierelements 136 in diesen Ausnehmungen 236 eine Fixierung des Crimpbereichs 130 in dem Steckverbindergehäuse 200 realisiert wird. Diese Fixierung verhindert bei einer Vibration, der ein solcher Stecker z.B. in einem Kraftfahrzeug ausgesetzt ist, dass es zu einer störenden Kontaktkorrosion und damit einer Unterbrechung des elektrischen Kontakts durch Widerstandserhöhung oder sogar zu einem Bruch des Kontaktelements 100 kommen kann.How out Fig. 4 and Fig. 6 shows are provided for the crimp-locking element 136 in the housing 200 recesses 236 which are adapted to the crimp-locking element 136 in such a way that by the arrangement of the arranged at the bottom of the crimp terminal crimp-locking element 136 in these recesses 236 a Fixation of the crimping 130 is realized in the connector housing 200. This fixation prevents vibration is exposed to such a connector, for example in a motor vehicle, that it leads to a disruptive contact corrosion and thus an interruption of the electrical contact Resistance increase or even a break of the contact element 100 can come.
