Description

Die Erfindung betrifft eine mehrpolige Steckverbinderanordnung mit einem ersten Steckverbinder, der ein erstes Steckverbindergehäuse aufweist und mit einem zweiten Steckverbinder, der ein zweites Steckverbindergehäuse aufweist, wobei in beiden Steckverbindergehäusen jeweils mehrere Kontaktelemente angeordnet sind, von denen zumindest die Kontaktelemente des ersten Steckverbindergehäuses jeweils mit einer Anschlussleitung verbunden sind, wobei das erste und das zweite Steckverbindergehäuse durch eine Rastverbindung miteinander verbunden sind, die durch einen CPA-Riegel gegen unbeabsichtigtes Trennen gesichert ist, und wobei der CPA-Riegel eine Federklammer ausbildet, die aus zwei einander gegenüberstehenden Federarmen besteht.The invention relates to a multi-pole connector arrangement with a first connector that has a first connector housing and with a second connector that has a second connector housing, with a plurality of contact elements being arranged in both connector housings, of which at least the contact elements of the first connector housing each have a connecting line are connected, wherein the first and second connector housings are connected to one another by a snap connection, which is secured against accidental disconnection by a CPA latch, and wherein the CPA latch forms a spring clip which consists of two opposing spring arms.

Eine derartige mehrpolige Steckverbinderanordnung ist aus der Druckschrift DE 699 22 451 T2 bekannt. Darin weist ein Verbindergehäuse einen CPA-Riegel mit zwei einander gegenüberstehende elastische Federarmen auf. Die Federarme dienen dazu den CPA-Riegel im Verbindergehäuse zu führen und zu arretieren.Such a multi-pole connector arrangement is from the publication DE 699 22 451 T2 known. Therein, a connector housing has a CPA latch with two opposing elastic spring arms. The spring arms are used to guide and lock the CPA latch in the connector housing.

Die Druckschrift US 2015/0162 693 A1 zeigt einen mehrpoligen Steckverbinder, der einen anfügbaren Leitungshalter aufweist, an dem mehrere Anschlussleitungen gebündelt werden können. Zur Befestigung der Anschlussleitungen ist eine separat zu montierende Klemme vorgesehen. Der Leitungshalter kann mit einer CPA-Vorrichtung verbunden ausgeführt sein.The publication US 2015/0162 693 A1 shows a multi-pin connector that has an attachable cable holder on which several connecting cables can be bundled. A separately mounted terminal is provided for fastening the connecting cables. The cable holder can be designed to be connected to a CPA device.

Eine weitere mehrpolige Steckverbinderanordnung mit einem CPA-Riegel ist aus der deutschen Offenlegungsschrift DE 10 2015 009 039 A1 bekannt.Another multi-pole connector arrangement with a CPA latch is from the German laid-open publication DE 10 2015 009 039 A1 known.

Bei mehrpoligen Steckverbinderanordnungen ergeben sich mit steigender Polzahl zunehmende Schwierigkeiten, die an den Kontaktelementen angebundenen Anschlussleitungen auf geordnete Weise wegzuführen. Ein übliches Vorgehen besteht darin, abgehende Anschlussleitungen mit Verbindungselementen, wie beispielsweise mit Kabelbindern, zu Leitungsbündeln zusammenzufassen. Sofern nicht besondere Befestigungsstellen für die Verbindungselemente an den Steckverbindergehäusen oder in der Anbauumgebung vorhanden sind, sorgen diese im Allgemeinen für keine ausreichende Fixierung des so geschaffenen Leitungsbündels.In multi-pole connector arrangements, the higher the number of poles, the more difficult it becomes to lead away the connecting cables connected to the contact elements in an orderly manner. A common approach is to combine outgoing connecting cables into cable bundles using connecting elements such as cable ties. Unless there are special fastening points for the connecting elements on the connector housings or in the installation environment, these generally do not ensure adequate fixation of the cable bundle created in this way.

Eine andere bekannte Möglichkeit zur Fixierung von Anschlussleitungen besteht darin, die Steckverbindergehäuse jeweils mehrteilig auszubilden und beim Zusammenfügen der Gehäuseteile die Anschlussleitungen zwischen den Gehäuseteilen einzuschließen. Dieses führt allerdings zu komplex aufgebauten und damit relativ kostenaufwendigen Steckverbindergehäusen.Another known possibility for fixing connecting cables is to design the connector housing in several parts and to enclose the connecting cables between the housing parts when the housing parts are joined together. However, this leads to connector housings that are complex and therefore relatively expensive.

Es stellte sich die Aufgabe, eine Steckverbinderanordnung zu schaffen, welche mit einem besonders geringen material- und montagetechnischen Aufwand die Befestigung einer Vielzahl von Anschlussleitungen ermöglicht.The task was to create a connector arrangement which enables the attachment of a large number of connecting cables with a particularly low level of material and assembly effort.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der CPA-Riegel zugleich einen Leitungshalter zur Befestigung mehrerer parallel aneinander liegend geführter Anschlussleitungen ausbildet, und dass in die Federklammer parallel gebündelte Anschlussleitungen eingesetzt und durch die Klemmkraft der Federklammer gehalten werden.This object is achieved according to the invention in that the CPA latch simultaneously forms a cable holder for fastening several connecting cables arranged parallel to one another, and in that parallel bundled connecting cables are inserted into the spring clamp and held by the clamping force of the spring clamp.

Somit ist der den Leitungshalter ausbildende Teil des CPA-Riegels als eine Federklammer ausgeführt, die aus zwei einander gegenüberstehenden Federarmen besteht. In die Federklammer werden parallel gebündelte Anschlussleitungen auf einfache Weise eingesetzt und von der Federklammer gehalten.The part of the CPA bar that forms the line holder is therefore designed as a spring clip which consists of two opposing spring arms. The spring clips are bundled in parallel Connecting cables are easily inserted and held by the spring clip.

Der der CPA-Riegel kann vorteilhaft als ein von den Steckverbindergehäusen unabhängig gefertigtes Einzelteil ausgebildet sein, welches durch Stecken mit wenigstens einem der Steckverbindergehäuse verrastbar ist.The CPA latch can advantageously be designed as a single part manufactured independently of the connector housings, which can be locked into place by plugging it into at least one of the connector housings.

Ebenfalls vorteilhaft kann dabei vorgesehen sein, die Anschlussleitungen vor dem Einsetzen in die Federklammer durch ein Verbindungselement zu einem Leitungsbündel zusammenzufassen.It can also be advantageous to combine the connecting cables into a cable bundle by means of a connecting element before inserting them into the spring clip.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung dargestellt und näher erläutert. Es zeigen

Die Figur 1 zeigt die Ansicht einer fertig montierten erfindungsgemäßen Steckverbinderanordnung. Diese besteht aus einem ersten und einem zweiten Steckverbinder 10, 20, deren Steckverbindergehäuse 12, 22 zusammengefügt sind und deren Verbindung durch einen CPA-Riegel 40 (CPA = Connector Position Assurance) gegen Trennen gesichert ist.The Figure 1 shows the view of a fully assembled connector arrangement according to the invention. This consists of a first and a second connector 10, 20, the connector housings 12, 22 of which are joined together and the connection of which is secured against disconnection by a CPA latch 40 (CPA = Connector Position Assurance).

Der CPA-Riegel 40 weist auf seiner von den Steckverbindergehäusen 12, 22 abstehenden Seite zwei einander gegenüberstehende Federarme 43 auf (deutlich erkennbar in der Figur 2), die ein Leitungsbündel 32 von Anschlussleitungen 30 klemmend halten.The CPA latch 40 has two opposite spring arms 43 on its side projecting from the connector housings 12, 22 (clearly visible in the Figure 2 ), which hold a cable bundle 32 of connecting cables 30 in a clamping manner.

Beide Steckverbindergehäuse 12, 22 weisen miteinander verbindbare elektrische Kontaktelemente wie etwa Steckhülsenkontakte und Steckerstifte auf, die in den Figuren jedoch nicht bildlich dargestellt sind.Both connector housings 12, 22 have electrical contact elements that can be connected to one another, such as socket contacts and plug pins, which, however, are not shown in the figures.

In der Figur 3 sind ein erstes Steckverbindergehäuse 12 und ein CPA-Riegel 40 jeweils als Einzelteile dargestellt. Darüber hinaus ist ein Verriegelungsschieber 50 abgebildet. Das erste Steckverbindergehäuse 12 weist mehrere Aufnahmekammern 48 auf, die in zwei parallelen Reihen angeordnet sind. Die Aufnahmekammern 48 sind dazu vorgesehen, hier nicht dargestellte elektrische Kontaktelemente rastend aufzunehmen.In the Figure 3 a first connector housing 12 and a CPA latch 40 are each shown as individual parts. In addition, a locking slide 50 is shown. The first connector housing 12 has a plurality of receiving chambers 48 which are arranged in two parallel rows. The receiving chambers 48 are intended to accommodate electrical contact elements, not shown here, in a latching manner.

Nach dem Einsetzen aller Kontaktelemente in die Aufnahmekammern 48 wird eine quaderförmig und länglich ausgebildete Verriegelungsplatte 52 des Verriegelungsschiebers 50 in einen Verriegelungskanal 19, welcher die gesamte Länge des ersten Steckverbindergehäuses 12 durchzieht, eingeschoben.After inserting all contact elements into the receiving chambers 48, a cuboid-shaped and elongated locking plate 52 of the locking slide 50 is inserted into a locking channel 19 which runs through the entire length of the first connector housing 12.

Ein am Verriegelungsschieber 50 angeordneter Rasthebel 54 verrastet dabei mit dem ersten Steckverbindergehäuse 12, wodurch der Verriegelungsschieber 50 am ersten Steckverbindergehäuse 12 fixiert ist.A locking lever 54 arranged on the locking slide 50 locks with the first connector housing 12, whereby the locking slide 50 is fixed on the first connector housing 12.

Die in den Verriegelungskanal 19 eingesetzte Verriegelungsplatte 52 hintergreift jeweils eine Freilassung an den Kontaktelementen und bewirkt so eine Sekundärverriegelung aller Kontaktelemente. Das Prinzip einer solchen Verriegelung ist beispielsweise aus der deutschen Patentschrift DE 103 32 892 B4 bekannt.The locking plate 52 inserted into the locking channel 19 engages behind a release on the contact elements and thus effects a secondary locking of all contact elements. The principle of such a lock is, for example, from the German patent DE 103 32 892 B4 known.

Das erste Steckverbindergehäuse 12 weist in der Mitte einer seiner Längsseiten eine Ausnehmung 13 in der Gehäusewand auf, innerhalb der ein federnder Hebel 17 angeordnet ist, an dem zwei bügelartige Rastelemente 15, 16 übereinander angeordnet sind.The first connector housing 12 has a recess 13 in the housing wall in the middle of one of its long sides, within which a resilient lever 17 is arranged, on which two bow-like locking elements 15, 16 are arranged one above the other.

Beidseitig neben der Ausnehmung 13 sind in die Gehäusewand des ersten Steckverbindergehäuses 12 jeweils übereinander drei Rastnuten 14 angeformt. Die Rastnuten 14 sind dazu vorgesehen, mit Raststegen 44 zusammenzuwirken, die an Seitenflächen des CPA-Riegels 40 angeformt sind. Zwischen den Seitenflächen des CPA-Riegels 40 ist zudem eine Anformung erkennbar, die einen Keil 46 ausbildet.On both sides next to the recess 13, three locking grooves 14 are formed one above the other in the housing wall of the first connector housing 12. The locking grooves 14 are intended to interact with locking webs 44 that are formed on the side surfaces of the CPA latch 40. Between the side surfaces of the CPA latch 40, a formation can also be seen that forms a wedge 46.

Der CPA-Riegel 40 ist über die Raststege 44 und die Rastnuten 14 mit dem ersten Steckverbindergehäuse 12 rastend verbindbar, wobei das Zusammenwirken der Raststege 44 und der Rastnuten 14 zumindest zwei Raststellungen des CPA-Riegels 40 am ersten Steckverbindergehäuse 12 ermöglicht, die im Folgenden als Vorraststellung und Endraststellung bezeichnet werden.The CPA bar 40 can be connected to the first connector housing 12 via the locking webs 44 and the locking grooves 14, the interaction of the locking webs 44 and the locking grooves 14 enabling at least two locking positions of the CPA bar 40 on the first connector housing 12, which are referred to below as Pre-locking position and final locking position are referred to.

Die Figur 4 zeigt den CPA-Riegel 40 in der Vorraststellung am ersten Steckverbindergehäuse 12. Hierbei sind die jeweils beiden Raststege 44 an den Seitenflächen des CPA-Riegels 40 in die obersten beiden Rastnuten 14 der Ausnehmung des ersten Steckverbindergehäuses 12 eingesetzt. Der Keil 46 des CPA-Riegels 40 befindet sich dabei zwischen dem oberen Rastelement 15 und dem unteren Rastelement 16 des ersten Steckverbindergehäuses 12.The Figure 4 shows the CPA latch 40 in the pre-locking position on the first connector housing 12. Here, the two locking webs 44 on the side surfaces of the CPA latch 40 are inserted into the top two locking grooves 14 of the recess of the first connector housing 12. The wedge 46 of the CPA latch 40 is located between the upper locking element 15 and the lower locking element 16 of the first connector housing 12.

Der federnde Hebel 17 ist dadurch weiterhin verschwenkbar, so dass beim Zusammenfügen des ersten Steckverbindergehäuses 12 mit dem zweiten Steckverbindergehäuse 22 das untere Rastelement 16 in die Rastausnehmung 24 des zweiten Steckverbindergehäuses 22 einrasten kann.The resilient lever 17 can thus continue to be pivoted so that when the first connector housing 12 is joined to the second connector housing 22, the lower locking element 16 can lock into the locking recess 24 of the second connector housing 22.

Danach wird der CPA-Riegel 40 durch Herunterdrücken in seine Endraststellung verbracht, wodurch sich der in den Figuren 1 und 2 dargestellte Montagezustand ergibt.The CPA bar 40 is then brought into its final locking position by pressing down, which means that it is in the Figures 1 and 2 shown assembly state results.

Wie die Schnittansicht der Figur 2 zeigt, untergreift in der Endraststellung der Keil 46 des CPA-Riegels 40 das untere Rastelement 16 und fixiert es in der Rastausnehmung 24 des zweiten Steckverbindergehäuses 22. Dadurch ist zugleich die Beweglichkeit des federnden Hebels 17 aufgehoben. Die beiden Steckverbindergehäuse 12, 22 sind dadurch untrennbar verbunden, solange der CPA-Riegel in seiner Endraststellung belassen wird.Like the sectional view of the Figure 2 shows, in the final locking position the wedge 46 of the CPA bar 40 engages under the lower locking element 16 and fixes it in the locking recess 24 of the second connector housing 22. This also eliminates the mobility of the resilient lever 17. The two connector housings 12, 22 are therefore inseparably connected as long as the CPA latch is left in its final locking position.

Bereits in der in der Figur 4 dargestellten Vorraststellung, und selbstverständlich auch in der in der Figur 1 dargestellten Endraststellung, erfüllt der CPA-Riegel 40 die weitere Funktion, die mit den Kontaktelementen des ersten Steckverbinderteils 10 verbundenen Anschlussleitungen am ersten Steckverbindergehäuse 12 zu fixieren. Hierzu sind die, optional durch ein zusätzliches Verbindungselement 34, wie etwa einen Kabelbinder oder ein Klebeband, zu einem Leitungsbündel 32 zusammengefassten Anschlussleitungen 30 in die zum CPA-Riegel 40 gehörende Federklammer 42 eingesetzt. Durch die Klemmkraft der beiden Federarme 43 der Federklammer 30 wird das Leitungsbündel 32 der Anschlussleitungen in einer zur Steckrichtung der beiden Steckverbinder 10, 20 annähernd rechtwinkligen Abgangsrichtung fixiert.Already in the Figure 4 shown pre-locking position, and of course also in the position shown in the Figure 1 In the final locking position shown, the CPA latch 40 fulfills the additional function of fixing the connecting cables connected to the contact elements of the first connector part 10 to the first connector housing 12. For this purpose, the connecting cables 30, which are optionally combined into a cable bundle 32 by an additional connecting element 34, such as a cable tie or adhesive tape, are inserted into the spring clip 42 belonging to the CPA latch 40. The clamping force of the two spring arms 43 of the spring clip 30 fixes the cable bundle 32 of the connecting cables in an outlet direction that is approximately at a right angle to the plug-in direction of the two connectors 10, 20.
