Im Gegensatz zu dem aus der DE 10 2008 055 841 A1 bekannten In contrast to the known from DE 10 2008 055 841 A1

Steckverbinderteil ist bei dem erfindungsgemäßen Steckverbinderteil zur Montage der Steckkontaktelemente kein Anfügen des Gehäuseteils an eine Lagerstelle und kein Anklappen des Gehäuseteils gegen den Gehäusekörper erforderlich. Gehäusekörper und Gehäuseteil sind zum Zeitpunkt der Montage der Steckkontaktelemente in einer stabilen Vorraststeilung miteinander vormontiert. In dieser Vorraststeilung bildet mindestens ein durch das Connector part is in the connector part according to the invention for mounting the plug contact elements no attachment of the housing part to a bearing point and no folding of the housing part against the housing body required. Housing body and housing part are pre-assembled with each other in a stable Vorraststeilung at the time of mounting the plug contact elements. In this Vorraststeilung forms at least one by the

Gehäuseteil ausgebildeter Verriegelungsarm zusammen mit dem Housing part trained locking arm together with the

Gehäusekörpers einen oder mehrere Vorsprünge aus, an denen die Housing body one or more projections on which the

Steckkontaktelemente einrasten können.

Gehäuseelementen klemmend eingeschlossen werden. Housing elements are trapped clamped.

Ebenfalls vorteilhaft ist, dass der mindestens eine Verriegelungsarm des Gehäuseteils hier mehrere Funktionen erfüllt. In der Vorraststeilung bildet er Rastvorsprünge am Gehäusekörper aus, die zur Fixierung der Rastfedern der Steckkontaktelemente dienen. Hierdurch brauchen entsprechende Vorsprünge nicht durch Anformungen am Gehäusekörper vorgesehen werden, was die Fertigung des Gehäusekörpers vereinfacht und kostengünstiger macht. In der Endraststellung fixiert der mindestens eine Verriegelungsarm sowohl die Rastfedern als auch die Kontaktkästen der Steckkontaktelemente. Das erfindungsgemäße Steckverbinderteil ermöglicht somit eine einfache Montage bei gleichzeitig besonders einfachen Aufbau seiner Komponenten.

Es zeigen It is also advantageous that the at least one locking arm of the housing part fulfills several functions here. In the Vorraststeilung it forms locking projections on the housing body, which serve to fix the detent springs of the plug contact elements. As a result, corresponding projections need not be provided by moldings on the housing body, which simplifies the manufacture of the housing body and makes it cheaper. In the final locked position, the at least one locking arm fixes both the detent springs and the contact boxes of the plug contact elements. The connector part according to the invention thus enables easy installation and at the same time particularly simple construction of its components.

Die Figur 1 zeigt eine Schnittansicht eines fertig zusammengefügten erfindungsgemäßen elektrischen Steckverbinderteils. Das Steckverbinderteil weist ein Gehäuse 10 aus zwei zusammengefügten und miteinander verrasteten Gehäuseelementen 1 , 2, nämlich einem Gehäusekörper 1 und einem Gehäuseteil 2 auf. Innerhalb des so gebildeten Gehäuses 10 ist in mindestens einer Aufnahmekammer 6 ein Steckkontaktelement 3 angeordnet, welches jeweils mit einer elektrischen Anschlussleitung 4 verbunden ist. FIG. 1 shows a sectional view of a completely assembled electrical connector part according to the invention. The connector part has a housing 10 made of two assembled and latched together housing elements 1, 2, namely a housing body 1 and a housing part 2. Within the housing 10 thus formed, a plug contact element 3 is arranged in at least one receiving chamber 6, which is in each case connected to an electrical connection line 4.

Jeweils ein mit einer isolierenden Ummantelung versehener Abschnitt 5 jeder Anschlussleitung 4 ist zwischen den Gehäuseelementen 1 , 2 aus dem In each case provided with an insulating sheath portion 5 of each connecting line 4 is between the housing elements 1, 2 of the

Gehäuse 10 des Steckverbinderteils herausgeführt. Housing 10 led out of the connector part.

Ein Steckkontaktelement 3 mit einer angebundenen Anschlussleitung 4 ist in einer Einzelansicht in der Figur 2 dargestellt. An einem vorderen Abschnitt des Steckkontaktelements 3 befindet sich ein Kontaktkasten 1 1 mit einer nach innen gebogenen streifenförmigen Kontaktzunge 18. Der zum Kontaktkasten 1 1 entgegensetzt gelegene Endabschnitt des Steckkontaktelements 3 ist als ein Crimpabschnitt 15 ausgeführt. An diesem Crimpabschnitt 15 ist durch einen Ader- beziehungsweise Litzencrimp eine elektrische Anschlussleitung 4 mechanisch befestigt und elektrisch angebunden. Das Steckkontaktelement 3 ist als ein, vorzugsweise einstückig geformtes, Stanzbiegeteil ausgeführt. Die obere Fläche des Kontaktkastens 1 1 wird durch einen angeformten Blechstreifen 13 gebildet, deren Längs- und Querkanten jeweils windschief zueinander ausgerichtet sind. Damit stehen verschiedene Punkte des Blechstreifens 13 verschieden hoch über der Grundfläche des Steckkontaktelements 3. Die weiter hervorstehenden Abschnitte des A plug contact element 3 with a connected connection line 4 is shown in a single view in FIG. At a front portion of the plug contact element 3 is a contact box 1 1 with an inwardly bent strip-shaped contact tongue 18. The contact box 1 1 opposite end portion of the plug contact element 3 is designed as a crimp section 15. At this crimp section 15, an electrical connection line 4 is mechanically fastened and electrically connected by a core or strand crimp. The plug contact element 3 is designed as a, preferably integrally formed, stamped and bent part. The upper surface of the contact box 1 1 is formed by a molded sheet metal strip 13, the longitudinal and transverse edges are each skewed aligned with each other. Thus, various points of the sheet metal strip 13 are at different heights over the base of the plug contact element 3. The further protruding portions of

Blechstreifens 13 können dadurch bei einer Kraftbeaufschlagung gegen die übrigen Abschnitte bewegt werden und aufgrund der elastischen Anbindung des Blechstreifens 13 am Steckkontaktelement 3 einfedern. Der Blechstreifen 13 an der oberen Fläche des Steckkontaktelements 3 bildet so eine Rastfeder 13 aus, die zur primären Verrastung des Steckkontaktelements 3 im Gehäuse 10 des Steckverbinderteils vorgesehen ist. Die Figur 3 zeigt in fünf Teilfiguren 3a bis 3e den Ablauf der Montage eines Steckverbinderteils durch das Zusammenfügen von Gehäusekörper 1 , Gehäuseteil 2 und mit mindestens einem Steckkontaktelement 3. Sheet metal strip 13 can thereby be moved with a force against the other sections and spring due to the elastic connection of the metal strip 13 on the plug contact element 3. The metal strip 13 on the upper surface of the plug contact element 3 thus forms a detent spring 13, which is provided for the primary latching of the plug contact element 3 in the housing 10 of the connector part. FIG. 3 shows, in five subfigures 3 a to 3 e, the sequence of the assembly of a connector part by the assembly of housing body 1, housing part 2 and with at least one plug contact element 3.

Wie bereits erwähnt, können der Gehäusekörper 1 und das Gehäuseteil 2 senkrecht zur vorgesehenen Steckrichtung des Steckverbinderteils in zwei Raststellungen zueinander positioniert werden, die hier als Vorraststellung und Endraststellung bezeichnet werden, wozu am Gehäusekörper 1 und am Gehäuseteil 2 zusammenwirkende mechanische Rastelemente angeordnet sind, die in den Schnittdarstellungen der Figuren allerdings nicht erkennbar sind. Da deren konkrete Ausgestaltungen für das Verständnis der Erfindung unerheblich sind, wird auf eine detaillierte Beschreibung hier verzichtet. As already mentioned, the housing body 1 and the housing part 2 can be positioned perpendicular to the intended insertion direction of the connector part in two locking positions to each other, which are referred to here as Vorraststellung and Endraststellung what the housing body 1 and the housing part 2 cooperating mechanical locking elements are arranged in The sectional views of the figures, however, are not recognizable. Since their concrete embodiments for the understanding of the invention are irrelevant, a detailed description is omitted here.

Bei der Montage der Steckkontaktelemente 3 sind der Gehäusekörper 1 und das Gehäuseteil 2 bereits in ihrer Vorraststellung miteinander verbunden. Die Vorraststellung, die in den Figuren 3a bis 3d dargestellt ist, ist eine erste stabile Anordnung von Gehäusekörper 1 und von Gehäuseteil 2 relativ zueinander, die dadurch gekennzeichnet ist, dass sich die Gehäuseelemente 1 , 2 in der Verbindungsrichtung senkrecht zur vorgesehenen Steckrichtung des Steckverbinderteils nicht im dichtest möglichen Abstand zueinander befinden. When mounting the plug contact elements 3, the housing body 1 and the housing part 2 are already connected to each other in their pre-locking position. The pre-locking position, which is shown in Figures 3a to 3d, is a first stable arrangement of the housing body 1 and the housing part 2 relative to each other, which is characterized in that the housing elements 1, 2 are not in the connecting direction perpendicular to the intended insertion direction of the connector part in the closest possible distance from each other.

Wie die Schnittansicht der Figur 3a zeigt, bilden die beiden Gehäuseelemente 1 , 2 einen kanalartigen Freiraum 16 aus, in den ein Steckkontaktelement 3 mit seiner Kontaktzunge 18 und seinem Kontaktkasten 1 1 voran eingeschoben werden kann. Das Ende des kanalartigen Freiraums 16 bildet eine As the sectional view of Figure 3a shows, form the two housing elements 1, 2 a channel-like space 16, in which a plug contact element 3 with its contact tongue 18 and its contact box 1 1 can be inserted ahead. The end of the channel-like free space 16 forms a

Aufnahmekammer 6, in der der Kontaktkasten 1 1 des Steckkontaktelements 3 befestigt werden soll. Recording chamber 6, in which the contact box 1 1 of the plug contact element 3 is to be attached.

Beim Einschieben des Steckkontaktelements 3 in den Freiraum 16 erreicht der Kontaktkasten 1 1 in der Figur 3b den Verriegelungsarm 7, dessen freier Endabschnitt 17 ein kleines Stück weit in den Freiraum 16 hineinragt. When inserting the plug contact element 3 in the free space 16 of the contact box 1 1 in the figure 3b reaches the locking arm 7, the free end portion 17 extends a little way into the space 16.

Der Endabschnitt 17 bildet eine hakenartige Kante aus, die mit einer entsprechen geformten Kante des Gehäusekörpers 1 eine widerhakenartige Verbindung 19 bildet. Diese widerhakenartige Verbindung 19 verhindert durch einen Formschluss ein versehentliches Trennen des Gehäusekörpers 1 vom Gehäuseteil 2. The end portion 17 forms a hook-like edge which forms a barb-like connection 19 with a correspondingly shaped edge of the housing body 1. This barb-like connection 19 prevents inadvertent separation of the housing body 1 from the housing part 2 by a positive connection.

Des Weiteren bildet der freie Endabschnitt 17 des Verriegelungsarms 7 an einem Wandabschnitt des Gehäusekörpers 1 in Richtung zur Furthermore, the free end portion 17 of the locking arm 7 forms on a wall portion of the housing body 1 in the direction of

Aufnahmekammer 6 einen Rastvorsprung 14 aus. Auf seiner oberen, der Aufnahmekammer 6 abgewandten Seite weist der freie Endabschnitt 17 des Verriegelungsarms 7 eine Führungsschräge 8 auf. Diese Führungsschräge 8 ermöglicht es der am Kontaktkasten 1 1 angeformten Rastfeder 13 sich beim Passieren des Verriegelungsarms 7 eng an den Kontaktkasten 1 1 anzulegen und dadurch am Endabschnitt 17 des Verriegelungsarms 7 vorbei zu gleiten (Figur 3c), ohne an diesem hängen zu bleiben. Beim weiteren Einschieben des Steckkontaktelements 3 rastet die Rastfeder 13 schließlich hinter dem durch den Verriegelungsarm 7 gebildeten Receiving chamber 6 a locking projection 14 from. On its upper, the receiving chamber 6 side facing away from the free end portion 17 of the locking arm 7 a guide bevel 8. This guide bevel 8 allows the contact box 1 1 integrally formed detent spring 13 to fit tightly against the contact box 1 1 when passing the locking arm 7 and thereby to slide past the end portion 17 of the locking arm 7 (Figure 3c), without hanging on this. Upon further insertion of the plug contact element 3, the detent spring 13 finally engages behind the one formed by the locking arm 7

Rastvorsprung 14 ein, was in der Figur 3d dargestellt ist. Das Detent projection 14, which is shown in the figure 3d. The

Steckkontaktelement 3 ist damit innerhalb des Gehäuses 10 bereits gegen ein Herausfallen gesichert. Plug contact element 3 is thus already secured within the housing 10 against falling out.

Bei einem mehrpoligen Steckverbinderteil werden entsprechend der In a multipolar connector part are corresponding to the

vorgesehenen Polzahl weitere Steckkontaktelemente 3 auf gleiche Weise in weitere Aufnahmekammern 6 des Gehäuses 10 eingesetzt, wobei jedesprovided pole number further plug-in contact elements 3 are inserted in the same way in further receiving chambers 6 of the housing 10, wherein each

Steckkontaktelement 3 zunächst durch die durch seine Rastfeder 13 bewirkte Primärverrastung in seiner Aufnahmekammer 6 gehalten wird. Plug contact element 3 is first held in its receiving chamber 6 by the effected by its detent spring 13 Primärverrastung.

Bei einem mehrpoligen Steckverbinderteil kann das Gehäuseteil 2 zudem entweder einen einzigen breiten Verriegelungsarm 7 aufweisen, der parallel Rastvorsprünge 14 an sämtlichen Aufnahmekammern 6 ausbildet oder es können auch mehrere schmale parallele Verriegelungsarme 7 vorgesehen sein, von denen jeweils einer mit jeweils einer der Aufnahmekammern 6 zusammenwirkt. In a multi-pin connector part, the housing part 2 may also have either a single wide locking arm 7, the parallel locking projections 14 formed on all receiving chambers 6 or it can also be provided several narrow parallel locking arms 7, one of which cooperates with each one of the receiving chambers 6.

Zum Abschluss der Montage werden der Gehäusekörper 1 und Gehäuseteil 2 durch eine äußere Kraftbeaufschlagung gegeneinander gedrückt und dadurch in ihre Endraststellung überführt (Figur 3e). Damit schiebt sich der mindestens eine Verriegelungsarm 7 über die Kontaktschultern 12, die durch die At the end of the assembly, the housing body 1 and the housing part 2 are pressed against each other by an external application of force and thereby transferred into their final locked position (FIG. 3e). Thus, the at least one locking arm 7 slides over the contact shoulders 12, which through the

Endabschnitte der Kontaktkästen 1 1 gebildet werden und fixiert die End portions of the contact boxes 1 1 are formed and fixes the

Steckkontaktelemente 3 formschlüssig in den Aufnahmekammern 6. Plug contact elements 3 positively in the receiving chambers. 6

Der mindestens eine Verriegelungsarm 7 bewirkt somit durch die Fixierung der Rastfedern 13 einerseits und der Kontaktkästen 1 1 an den Kontaktschultern 12 andererseits sowohl eine primäre als auch eine sekundäre Verriegelung der Steckkontaktelemente 3. Dabei erfolgen beide Verriegelungen innerhalb des Gehäuses 10 in einer einzigen Verriegelungsebene, was zur Realisierung einer besonders kompakten Ausführung des Steckverbinderteils vorteilhaft beiträgt. The at least one locking arm 7 thus effected by the fixation of the detent springs 13 on the one hand and the contact boxes 1 1 on the contact shoulders 12 on the other hand, both a primary and a secondary locking of the plug contact elements 3. Here are both locks within the housing 10 in a single locking plane, which for realization a particularly compact design of the connector part advantageously contributes.

In der Endraststellung, die in den Figuren 1 und 3e dargestellt ist, ist wiederum eine stabile Positionierung der Gehäuseelemente 1 , 2 zueinander erreicht, wobei die Gehäuseelemente 1 , 2 jetzt eine kompakte Anordnung miteinander bilden. In the final locked position, which is shown in Figures 1 and 3e, in turn, a stable positioning of the housing elements 1, 2 is achieved to each other, wherein the housing elements 1, 2 now form a compact arrangement with each other.

Beim Erreichen der Endraststellung fügt sich zudem ein oberer Abschnitt 9 des Gehäuseteils 2 eng an die ummantelten Abschnitte 5 der Anschlussleitungen 4 an und presst diese gegen den Gehäusekörper 1 . Hierdurch werden die Anschlussleitungen 4 kraftschlüssig zwischen den Gehäuseelementen 1 , 2 fixiert. Mit dem Erreichen der Endraststellung ist die Montage des When reaching the final locked position, moreover, an upper section 9 of the housing part 2 fits snugly against the sheathed sections 5 of the connection lines 4 and presses them against the housing body 1. As a result, the connection lines 4 are frictionally fixed between the housing elements 1, 2. With the achievement of the final locked position, the assembly of the
