Description

Die Erfindung betrifft eine Verriegelungseinrichtung für Steckverbinder-Gehäusehälften, gebildet aus einem Gehäuseoberteil und einem Gehäuseunterteil mit einem das Gehäuseoberteil umfassenden, axial verschiebbaren, Entriegelungsring.The invention relates to a locking device for connector housing halves, formed from an upper housing part and a lower housing part with an upper part of the housing, axially displaceable, unlocking ring.

Eine derartige Verriegelungseinrichtung wird benötigt, um zwei Steckerverbindergehäuse im gesteckten Zustand formschlüssig zu verrasten und ein unbeabsichtigtes Lösen der Verbindung durch Vibration oder Zugkräfte zu unterbinden.Such a locking device is required to positively lock two plug connector housing in the inserted state and to prevent unintentional release of the connection by vibration or tensile forces.

Aus der DE 42 05 960 C2 ist eine Steckverbindung mit verriegelbaren Gehäusehälften bekannt, bei der Verriegelungselemente mit federnden Rastklinken vorgesehen sind, die in einer, im gesteckten Zustand die beiden Gehäusehälften umgebenden, Hülse angeordnet sind, wobei die in einer Gehäusehälfte angeordneten Rastklinken in Ausnehmungen der anderen Gehäusehälfte verrasten. Bei einer Ziehbewegung der Hülse werden die Rastklinken aus den Ausnehmungen heraus gehebelt und die Steckverbindung ist entriegelt.From the DE 42 05 960 C2 is a connector with lockable housing halves are known, are provided in the locking elements with resilient latching pawls, which are arranged in a, in the inserted state, the two housing halves, sleeve, said arranged in a housing half latching latch in recesses of the other housing half. During a pulling movement of the sleeve, the detents are levered out of the recesses and the connector is unlocked.

US-A-5 718 596 offenbart eine Verriegelungseinrichtung nach dem Oberbegriff des Anspruchs 1. US-A-5 718 596 discloses a locking device according to the preamble of claim 1.

Die Aufgabe dieser Erfindung ist, eine Verriegelungseinrichtung für Steckverbinder der eingangs genannten Art, dahingehend zu entwickeln, dass neben einer Verrastung der beiden Stecker eine zusätzliche Verriegelung vorgesehen ist.The object of this invention is to develop a locking device for connectors of the type mentioned in that in addition to a locking of the two plugs an additional lock is provided.

Diese Aufgabe wird dadurch gelöst, dass der Entriegelungsring mindestens eine dreiseitig freistehende und nach innen bewegbare Betätigungslasche aufweist, an der eine Freigabeklinke mit einer nach innen gerichteten Abwinklung angeformt ist, dass an dem Gehäuseoberteil eine nach außen weisende Sperrklinke mit einer Abwinklung angeformt ist, und dass die Abwinklung im verriegelten Zustand des Steckverbinders an die Abwinklung der vom Gehäuseoberteil nach außen weisenden Sperrklinke anschlagend angeordnet ist.This object is achieved in that the unlocking ring at least one three-sided freestanding and inwardly movable actuating tab has, on which a release latch is formed with an inwardly directed bend, that on the housing upper part an outwardly facing pawl is formed with an angled, and that the bend in the locked state of the connector to the bend of the housing top outwardly facing pawl hinged is arranged.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 - 7 angegeben.Advantageous embodiments of the invention are specified in claims 2-7.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass in der hier gezeigten Steckverbindung die Kombination einer Verrastung und einer zusätzlichen Verriegelung für einen Stecker und einen Gegenstecker verwirklicht ist.
Dabei ist zunächst ein hochbelastbarer Verrastungsmechanismus, ausgeführt als so genannte Push-Pull-Verrastung, in aus metallischen oder nichtmetallischen Material bestehenden Steckverbindergehäusen mit einer Verriegelung kombiniert, die in einem beide Gehäuse umfassenden Entriegelungsring angeordnet ist.
In dem Entriegelungsring sind Verrastungs- und Verriegelungsmittel vorgesehen, die vorteilhafterweise bei einem normalen Steckvorgang zunächst eine Verrastung und dann eine zusätzliche Verriegelung der beiden Steckverbindergehäuse bewirken.
An dem Entriegelungsring sind Betätigungslaschen vorgesehen, mittels derer die Verriegelungsmittel vorteilhaft freigegeben werden und beim nahezu gleichzeitigen Ziehen des Steckers auch die Verrastung der Steckverbindung freigegeben wir.
Während die Verriegelungsmittel aus dem Material bestehen, aus dem Stecker und Entriegelungsring gefertigt sind, so ist der Verrastungsmechanismus, als federndes Verrastungsblech, vorzugsweise aus metallischem Material gefertigt und die Rastnasen aus dem Material des Gegensteckers.The advantages achieved by the invention are in particular that in the connector shown here, the combination of a latch and an additional latch for a plug and a mating connector is realized.
In this case, a heavy-duty latching mechanism, designed as a so-called push-pull latching, is first combined in plug-in housings made of metallic or non-metallic material with a latch which is arranged in an unlocking ring comprising both housings.
In the unlocking latching and locking means are provided, which advantageously cause a latching and then an additional locking of the two connector housing in a normal mating operation.
At the unlocking ring actuating tabs are provided, by means of which the locking means are advantageously released and the almost simultaneous pulling of the plug and the locking of the connector we released.
While the locking means consist of the material, are made of the plug and unlocking ring, the latching mechanism, as a resilient Verrastungsblech, preferably made of metallic material and the locking lugs of the material of the mating connector.

Dabei weist das gestanzte Verrastungsblech mindestens einen fensterartigen Ausschnitt auf, vorzugsweise jedoch zwei getrennte Ausschnitte, in den entsprechende am Gegenstecker angeformte Rastnasen eingreifen.
Ein metallisches Verrastungsblech ist insofern vorteilhaft, als dass, unabhängig vom Steckergehäusematerial, das Verrastungsblech als so genannter PE-Kontakt zur Übertragung des Bezugserde-Signals genutzt werden kann.In this case, the stamped Verrastungsblech on at least one window-like cutout, but preferably two separate cutouts, engage in the corresponding mating plug molded on the locking lugs.
A metal latching plate is advantageous in that, regardless of the plug housing material, the latching plate can be used as a so-called PE contact for transmitting the reference ground signal.

In der Fig.1 ist in einer perspektivischen Ansicht eine Steckerkombination 1 dargestellt, bestehend aus einem Stecker 2 und einem Gegenstecker 3, mit einem daran angeformten Befestigungsflansch.
Die Stecker und Gegenstecker sind im weiteren Verlauf als Gehäuseoberteil 20 und Gehäuseunterteil 30 definiert.
Die beiden Gehäuseteile sind von einem Entriegelungsring 10 umgebenden, wobei hier die vordere Hälfte des Entriegelungsringes ausgeblendet ist, so dass zumindest ein Teil der hier vorzustellenden Verrastungs- und Verriegelungsvorrichtung sichtbar ist.
Beidseitig an den Schmalseiten der Gehäuseteile ist innerhalb des Entriegelungsringes 10 jeweils ein Verrastungsblech 40 erkennbar, das an dem Gehäuseoberteil 20 fixiert ist..
Mittels einer Kröpfung 44 reicht das Verrastungsblech 40 über einen umlaufenden Bund 21 am unteren Rand des Gehäuseoberteils bis an zwei, aus dem Gehäuseunterteil 30 hervorragende Rastnasen 32, an denen es verrastet ist.In the Fig.1 is shown in a perspective view a connector combination 1, consisting of a plug 2 and a mating connector 3, with a mounting flange molded thereto.
The plug and mating connector are defined in the further course as the upper housing part 20 and the lower housing part 30.
The two housing parts are surrounded by an unlocking ring 10, in which case the front half of the unlocking ring is hidden, so that at least part of the Verrastungs- and locking device to be presented here is visible.
On both sides of the narrow sides of the housing parts a latching plate 40 can be seen within the unlocking ring 10, which is fixed to the housing upper part 20 ..
By means of a crank 44, the Verrastungsblech 40 extends over a circumferential collar 21 at the bottom of the upper housing part to two, from the lower housing part 30 outstanding locking lugs 32, where it is locked.

Oberhalb des Verrastungsbleches 40 ist eine schmale Leiste 22 angeformt, während etwas tiefer eine Anformung des Gehäuseoberteiles aus der Mitte des Verrastungsbleches hervorragt, die weiter unter als Sperrklinke 25 beschrieben ist.
Hier nicht so ohne Weiteres erkennbar ist, dass die Sperrklinke 25 zum Teil beabstandet von der Wand an der Schmalseite 23 angeformt ist, so dass ein Schlitz 24 gebildet ist, in den das Verrastungsblech 40 einschiebbar ist, bis es unterhalb der Leiste 22 verrastet ist. (Siehe dazu auch Fig. 5)Above the Verrastungsbleches 40, a narrow bar 22 is formed, while slightly deeper protrudes a molding of the upper housing part of the middle of the Verrastungsbleches, which is further described below as pawl 25.
Here it is not so readily apparent that the pawl 25 is formed partially spaced from the wall on the narrow side 23, so that a slot 24 is formed, in which the Verrastungsblech 40 is inserted until it is latched below the bar 22. (See also Fig. 5 )

In der Fig. 2 a-c ist das Verrastungsblech 40 in einigen Varianten im Detail dargestellt, das beidseitig an den Schmalseiten 23 des Gehäuseoberteiles 2 verrastend anzufügen ist.
Das Verrastungsblech ist als metallisches Stanzteil ausgeführt und mit einem fensterartigen Ausschnitt 42 versehen, wobei der Ausschnitt als gemeinsames Fenster oder in zwei separaten Fenster unterteilt sein kann. (Siehe Fig. 2a, 2b)
Die hier untere Kante ist als Schräge 43 abgewinkelt, so dass eine Einlaufschräge zur Auslenkung des Bleches beim Auftreffen auf die Rastnasen 32 am Gehäuseunterteil 3 entsteht.
Weiterhin sind die beiden senkrechten Streben 44 etwa in der Mitte gekröpft, damit die untere Kante über den Bund 21 an dem Gehäuseoberteil 20 hinweg an den Rastnasen 32 des Gehäuseunterteiles anschlagen bzw. dort verrasten kann.
Etwa mittig des Verrastungsbleches 40 ist eine Haltekontur 41 vorgesehen, mittels der eine Fixierung an den Schmalseiten 23 des Gehäuseoberteiles in einer dort vorgesehenen schlitzförmigen Aufnahme 24 erfolgt.
An der hier oberen Kante des Verrastungsbleches kann eine rechtwinklig abgebogene Halte- oder Führungsvorrichtung 45 vorgesehen sein, die eine stabilisierende Halterung des übergestülpten Entriegelungsringes 10 ermöglicht.
Darüber hinaus ist auch eine Variante (Fig. 2c) gezeigt, in der das Verrastungsblech als PE-Federkontakt 46 ausgebildet ist.
Zudem sind unterschiedliche Haltekonturen 41 zur Fixierung des Verrastungsbleches an den Schmalseiten des Gehäuseoberteiles in den Fig. 2a-c gezeigt.
Die Fig. 3 zeigt einen Ausschnitt des Gehäuseoberteiles 20 mit seiner Schmalseite 23 auf der das Verrastungsblech 40 verrastet ist.
Dabei ist erkennbar, wie das Verrastungsblech hinter einem aus dem Bund 21 herausgeformten, nach oben ragenden, und von der Schmalseite 23 beabstandeten Flächenelement 28, in dem so gebildeten Schlitz 24 fixiert ist. Auf diesem Flächenelement 28 ist die Sperrklinke 25 angeordnet, die zweiseitig über eine Ecke an dem Flächenelement angeformt ist, während die diagonal gegenüberliegende Ecke freigestellt ist, so dass eine taschenähnliche Struktur zum Hintergreifen gebildet ist.
In diese Tasche 27 greift bei der Entriegelung, wie weiter unten erklärt ist, eine Freigabeklinke 15 ein.In the Fig. 2 ac the Verrastungsblech 40 is shown in some variants in detail, which is on both sides of the narrow sides 23 of the upper housing part 2 to add latching.
The Verrastungsblech is designed as a metallic stamped part and provided with a window-like cutout 42, wherein the cutout can be divided as a common window or in two separate windows. (Please refer Fig. 2a, 2b )
The lower edge here is angled as a slope 43, so that an inlet slope for deflecting the sheet when hitting the locking lugs 32 on the housing base 3 is formed.
Furthermore, the two vertical struts 44 are bent approximately in the middle, so that the lower edge on the collar 21 on the upper housing part 20 away against the latching lugs 32 of the housing base abut or can lock there.
Approximately in the middle of the Verrastungsbleches 40, a holding contour 41 is provided by means of a fixation on the narrow sides 23 of the upper housing part in a slot-shaped receptacle 24 provided there.
At the upper edge of the Verrastungsbleches here a right angle bent holding or guiding device 45 may be provided which allows a stabilizing support of the slipped unlocking ring 10.
In addition, a variant ( Fig. 2c ), in which the latching plate is designed as a PE spring contact 46.
In addition, different retaining contours 41 for fixing the Verrastungsbleches on the narrow sides of the upper housing part in the Fig. 2a-c shown.
The Fig. 3 shows a section of the upper housing part 20 with its narrow side 23 on which the Verrastungsblech 40 is locked.
It can be seen how the Verrastungsblech behind a formed out of the collar 21, upwardly projecting, and spaced from the narrow side 23 surface element 28, is fixed in the slot 24 thus formed. On this surface element 28, the pawl 25 is arranged, which is integrally formed on two sides over a corner of the surface element, while the diagonally opposite corner is free, so that a bag-like structure is formed for engaging behind.
In this pocket 27 engages in the unlocking, as explained below, a release latch 15 a.

In der Fig. 4 sind in einem vergrößerten Ausschnitt einer perspektivischen Ansicht des Gehäuseoberteiles 20, mit einem teilweise ausgeblendeten Entriegelungsring 10, die weiteren für die Verriegelung erforderlichen Teile gezeigt.
Dabei ist hier links ein Teil des Entriegelungsringes 10 gezeigt, mit einer hervorstehenden, dreiseitig freistehenden Betätigungslasche 14, an deren Innenseite die Freigabeklinke 15 angeformt ist. Oberhalb der Freigabeklinke 15 ist die aus der Schmalseite des Gehäuseoberteiles 20 hervorragende Sperrklinke 25 angeordnet.
Weiterhin sind zwei aus dem Entriegelungsring hervorragende Verrastungselemente 12 erkennbar, mittels derer die zweite Hälfte des hier ausgeblendeten Entriegelungsringes zu verbinden bzw. zu verrasten ist.In the Fig. 4 are shown in an enlarged detail of a perspective view of the upper housing part 20, with a partially hidden unlocking ring 10, the other required for the locking parts.
Here, a part of the unlocking ring 10 is shown here on the left, with a protruding, three-sided freestanding operating tab 14, on the inside of the release latch 15 is formed. Above the release latch 15, the outstanding from the narrow side of the upper housing part 20 pawl 25 is arranged.
Furthermore, two outstanding from the unlocking Verrastungselemente 12 can be seen, by means of which the second half of the unlocked here unlocking ring to connect or to lock.

In der Fig. 5 ist in einer Seitenansicht der beiden verrasteten Gehäuseteile 20, 30 und dem Entriegelungsring 10 die Anordnung des Verrastungsbleches 40 am Gehäuseoberteil 20 gezeigt.In the Fig. 5 is shown in a side view of the two latched housing parts 20, 30 and the unlocking ring 10, the arrangement of Verrastungsbleches 40 on the upper housing part 20.

Dabei ist erkennbar, wie das Verrastungsblech 40 im Schlitz 24 hinter dem Flächenelement 28 eingeschoben ist und von der Leiste 22 gegen ein Herausrutschen gesichert ist.
Weiterhin ist die Verrastung des Verrastungsbleches 40 an der Rastnase 32 am Gehäuseunterteil 30 gezeigt und das unterhalb der Schräge 43 positionierte, am Entriegelungsring 10 angeformte Schrägelement 18.
Wobei anzumerken ist, dass die Schrägelemente 18 in den Eckbereichen des Entriegelungsringes angeordnet sind und sich somit außerhalb der Anordnung der Rastnasen 32 am Gehäuseunterteil befinden.It can be seen how the Verrastungsblech 40 is inserted in the slot 24 behind the surface element 28 and is secured by the bar 22 against slipping out.
Furthermore, the locking of Verrastungsbleches 40 is shown on the locking lug 32 on the housing base 30 and positioned below the slope 43, integrally formed on Entriegelungsring 10 oblique element 18th
It should be noted that the oblique elements 18 are arranged in the corner regions of the unlocking ring and thus are outside the arrangement of the locking lugs 32 on the housing lower part.

Die Fig. 6 a-d zeigen in einem speziellen Schnitt durch die Schmalseite 23, 33 der beiden gesteckten Gehäusehälften 20, 30 die Funktionsweise des Verrastungs- und des Verriegelungsmechanismus.
Im verriegelten Zustand sind die beiden Verriegelungselemente, die Sperrklinke 25 und die Freigabeklinke 15 mit ihren hier senkrecht gegeneinander stehenden Abwinkelungen 16, 26 unmittelbar übereinander angeordnet. (Fig. 6b)
Durch einen Druck (entsprechend Pfeil D) auf die Betätigungslasche 14 am Entriegelungsring 10 wird die untere Freigabeklinke 15 nach innen gedrückt und gelangt in die Tasche 27 unterhalb der Sperrklinke 25. (Fig. 6c)
Damit ist die Verriegelung freigegeben und der Entriegelungsring 10 kann (entsprechend Pfeil Z) angehoben werden. (Fig. 6d)
Gleichzeitig greifen jetzt die Schrägelemente 18 am Entriegelungsring 10, die unterhalb der Schräge 43 an dem Verrastungsblech 40 angeordnet sind, gegeneinander, womit der untere Teil des Verrastungsbleches seitlich nach außen gezogen wird und die Verrastung mit den Rastnasen 32 am Gehäuseunterteil 30 aufhebt und so das Gehäuseoberteil 20 vom Gehäuseunterteil 30 beziehungsweise Stecker 2 und Gegenstecker 3 endgültig trennt.The Fig. 6 ad show in a special section through the narrow side 23, 33 of the two inserted housing halves 20, 30, the operation of the Verrastungs- and the locking mechanism.
In the locked state, the two locking elements, the pawl 25 and the release latch 15 are arranged directly above one another here with their right angles to each other bends 16, 26. ( Fig. 6b )
By a pressure (corresponding to arrow D) on the actuating lug 14 on Entriegelungsring 10, the lower release latch 15 is pressed inwards and enters the pocket 27 below the pawl 25. ( Fig. 6c )
Thus, the lock is released and the release ring 10 can be raised (corresponding to arrow Z). ( Fig. 6d )
At the same time now grab the oblique elements 18 on Entriegelungsring 10, which are arranged below the slope 43 on the Verrastungsblech 40 against each other, whereby the lower part of Verrastungsbleches is pulled laterally outwards and the catch with the locking lugs 32 on the housing base 30 picks up and so the upper housing part 20 from the housing base 30 or plug 2 and mating connector 3 finally separates.
