Description

Die Erfindung betrifft eine Verriegelungsvorrichtung für Steckverbindergehäuse nach dem Oberbegriff des Anspruchs 1The invention relates to a locking device for connector housing according to the preamble of claim 1

Eine derartige Verriegelungsvorrichtung wird benötigt, um zwei Steckverbindergehäusehälften umweltsicher miteinander zu verbinden.Such a locking device is required to environmentally secure two connector housing halves together.

Stand der TechnikState of the art

Die Druckschrift DE 29 15 574 C2 offenbart einen Gehäusehälften-Verschluss für mehrpolige elektrische Steckvorrichtungen mit einem oder auch zwei um Lagerzapfen eines Gehäuseunterteils schwenkbaren, aus Federstahldraht hergestellten Verschlussbügeln. Ein solcher Verschlussbügel ist mit Ösen, einem ersten Ω-ähnlich gebogenen Federabschnitt, einem Rasthaken mit einer Aufgleitrundung und einem zweiten Ω-ähnlich gebogenen Federabschnitt ausgerüstet. Weiterhin wird offenbart, dass ein Griffteil auf den Verschlussbügel aufrastbar ist. Während des Schließvorgangs wird die Öffnungsweite des ersten Ω-ähnlichen Federabschnitts durch eine am Verbindungsabschnitt wirkende Kraft vergrößert. Dadurch werden Aufgleitrundungen des Verschlussbügels nach oben gebogen und können so über einen Lagerzapfen des Gehäuseoberteils gleiten. Weiterhin wird auch der Entriegelungsvorgang durch den vorgeschlagenen Gehäusehälften-Verschluss erleichtert.The publication DE 29 15 574 C2 discloses a housing half-lock for multipolar electrical plug-in devices with one or two pivotable about bearing pin of a housing base, made of spring steel wire fasteners. Such a closure clip is equipped with eyelets, a first Ω-like curved spring section, a latching hook with a Aufgleitrundung and a second Ω-like curved spring section. Furthermore, it is disclosed that a grip part can be latched onto the closure bow. During the closing operation, the opening width of the first Ω-like spring portion is increased by a force acting on the connecting portion. As a result Aufgleitrundungen the locking bracket are bent upwards and can slide over a bearing pin of the upper housing part. Further, too the unlocking process facilitated by the proposed housing half-lock.

Eine solche Vorrichtung erfordert eine hohe Elastizität des Verschlussbügels, wodurch sich ihre Verriegelungskräfte verringern. Weiterhin ist diese Vorrichtung dadurch auch in ihrer Handhabung nicht stabil.Such a device requires a high elasticity of the closure bracket, thereby reducing their locking forces. Furthermore, this device is therefore not stable in their handling.

Aus der EP 0 731 534 B1 ist eine elektrische Steckverbindung bekannt, bei der ein U-förmiger um Lagerzapfen einer Steckverbindungshälfte schwenkbarer Verriegelungsbügel in seinen Seitenteilen Taschen aufweist, in denen jeweils ein speziell geformtes Federelement angeordnet ist, das in Zusammenhang mit einem an der zweiten Gehäusehälfte angeordneten Verriegelungszapfen eine Verriegelung der Steckverbindung ermöglicht. Für eine solche Verriegelungsvorrichtung sind weiterhin mehrere kleine Einzelteile und eine aufwendige Erstellung des Verriegelungsbügels erforderlich.From the EP 0 731 534 B1 an electrical connector is known in which a U-shaped pivotable about bearing pin of a connector half locking bracket in its side parts pockets, in each of which a specially shaped spring element is arranged, which allows in connection with a arranged on the second housing half locking pin locking the connector , For such a locking device still several small items and a complex creation of the locking bracket are required.

Auch sind Verriegelungsvorrichtungen dieser Bauart bekannt, deren Verriegelungsbügel im wesentlichen aus elastischem Kunststoff gefertigt sind, und die so elastisch gebogen über die Lagerzapfen einer bestehenden Steckverbindergehäusehälfte geschoben und dort eingeklinkt werden können. Diese Verriegelungsbügel sind jedoch für viele Anwendungen nicht ausreichend umweltresistent und sind insbesondere für viele Anwendungen nicht hitzebeständig genug, beispielsweise beim Betrieb in der Nähe eines Hochofens.Also locking devices of this type are known, the locking bracket are made essentially of elastic plastic, and so elastically bent pushed over the bearing pin of an existing connector housing half and can be latched there. However, these locking straps are not sufficiently resistant to the environment for many applications and, in particular, are not heat-resistant enough, in particular for use in the vicinity of a blast furnace, for many applications.

In der Vergangenheit hat sich gezeigt, dass die Verriegelungsvorrichtungen von Steckverbindern insbesondere unter extremen Umweltbelastungen wie beispielsweise Hitze oder Feuchtigkeit besonders hohe Verschleißerscheinungen aufweisen. Diese Verschleißerscheinungen zeigen sich oft erst im Einsatz, wenn die Steckverbinder bereits am Einsatzort installiert sind. Ein Nachteil im Stand der Technik besteht somit darin, dass die ursprünglichen Verriegelungsvorrichtungen bestehender Steckverbinder nicht oder nur mit großem Aufwand gegen entsprechend umweltresistentere, insbesondere hitzebeständigere Verriegelungsvorrichtungen ausgetauscht werden können.In the past, it has been found that the locking devices of connectors, especially under extreme environmental conditions such as heat or moisture have particularly high signs of wear. These signs of wear often show up only when the connectors are already installed in the field. A disadvantage of the prior art is thus that the original locking devices existing connector can not or only with great effort against corresponding more environmentally resistant, especially heat-resistant locking devices can be replaced.

Aufgabenstellungtask

Der Erfindung liegt daher die Aufgabe zugrunde, eine mechanisch möglichst einfache und kostengünstige Verriegelung für zwei zusammengehörige Steckverbindergehäusehälften zu schaffen und dabei die vorgenannten Nachteile zu vermeiden.The invention is therefore an object of the invention to provide a mechanical as simple and inexpensive locking for two associated connector housing halves, while avoiding the aforementioned disadvantages.

Diese Aufgabe wird durch eine Verriegelungsvorrichtung mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved by a locking device having the features of the characterizing part of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 - 9 angegeben.Advantageous embodiments of the invention are specified in claims 2-9.

Bei der Erfindung handelt es sich um eine Verriegelungsvorrichtung für Steckverbindergehäuse, insbesondere für sogenannte "Schwerlaststeckverbinder", bei denen die beiden Gehäusehälften so gegeneinander verriegelbar sein müssen, dass ein umweltsicherer Schutz innenliegender Steckerkörper gewährleistet ist.In the invention, it is a locking device for connector housing, in particular for so-called "heavy-duty connectors", in which the two housing halves must be locked against each other so that an environmentally safe protection of internal connector body is guaranteed.

Die lösbare Verbindung zwischen dem jeweiligen Verriegelungslement und dem Betätigungsgriff ist vorteilhafterweise dazu geeignet, eine neue, umweltresistente Verriegelungsvorrichtung problemlos an ein bereits bestehendes Steckverbindersystem anzubringen, wodurch die Nachrüstung bestehender Steckverbindersysteme erheblich erleichtert wird.The detachable connection between the respective Verriegelungslement and the operating handle is advantageously adapted to easily attach a new, environmentally resistant locking device to an existing connector system, whereby the retrofitting of existing connector systems is greatly facilitated.

Insbesondere ist es somit von Vorteil, dass eine solche Verriegelungsvorrichtung nachträglich beispielsweise am Einsatzort und an bereits installierten Gehäusehälften montiert werden kann. Dadurch wird der Austausch einer weniger umweltresistenten Verriegelungsvorrichtung gegen eine entsprechend umweltresistentere Verriegelungsvorrichtung erheblich erleichtert.In particular, it is thus advantageous that such a locking device can be retrofitted, for example, at the site and on already installed housing halves. As a result, the replacement of a less environmentally resistant locking device against a more environmentally resistant locking device is greatly facilitated.

Weitere mit der Erfindung erzielten Vorteile bestehen darin, dass die Verriegelungsvorrichtung einen austauschbaren Betätigungsgriff, in welchen zwei zueinander spiegelsymmetrische Verriegelungselemente verrastend einsetzbar sind, aufweist.Further advantages achieved by the invention are that the locking device has a replaceable operating handle, in which two mutually mirror-symmetrical locking elements can be latched, has.

Weiterhin wird mit der Verriegelungsvorrichtung, wie im Folgenden beschrieben, ein besonders vorteilhaftes Verhältnis zwischen Betätigungs- und Haltekräften erreicht. Bei dem Verriegelungsvorgang wird durch entsprechendes Betätigen des Betätigungsgriffs das zum ersten Schenkelende führende Endstück vom Lagerzapfen elastisch weggebogen und gleichzeitig wird das zum zweiten Schenkelende führende Endstück zum dazugehörigen Arretierzapfen elastisch hingebogen. Somit ist eine Anhebung der Aufgleitrundungen gewährleistet, wodurch diese beim Verriegelungsvorgang mit vergleichsweise geringem Kraftaufwand über die Arretierzapfen gleiten können. Das damit erzielte besonders vorteilhafte Verhältnis zwischen Betätigungs- und Haltekräften ist insbesondere für Schwerlaststeckverbinder von großer Bedeutung, weil durch die hohen Haltekräfte ein umweltsicherer Schutz der innenliegenden Steckkörper gewährleistet ist.Furthermore, a particularly advantageous relationship between actuation and holding forces is achieved with the locking device, as described below. In the locking operation, the end leg leading to the first leg end is elastically bent away from the bearing journal by corresponding actuation of the actuating handle, and at the same time the end piece leading to the second leg end is elastically bent towards the associated locking pin. Thus, an increase in the Aufgleitrundungen is guaranteed, allowing them to slide over the locking pin with relatively little effort during the locking process. The thus achieved particularly advantageous relationship between actuation and holding forces is particularly important for heavy-duty connectors of great importance, because the high holding forces an environmentally safe protection of the inner plug body is guaranteed.

Auch hat sich in der Praxis gezeigt, dass bei bestimmten Steckverbinderanordnungen die Betätigungskräfte beim Verriegeln das eigentliche Problem darstellen, während die Betätigungskräfte bei der Entriegelung vergleichsweise weniger problematisch sind. Somit ist die Optimierung der Verriegelungsvorrichtung zugunsten einer Verringerung der Betätigungskräfte beim Verriegeln für eine solche Steckverbinderanordnung von besonderem Vorteil. Weiterhin können die Drahtelemente zweckmäßigerweise als Drahtbiegeteile aus Federstahldraht gefertigt sein.Also, it has been found in practice that in certain connector assemblies, the actuating forces during locking represent the real problem, while the actuating forces are relatively less problematic when unlocking. Thus, the optimization of the locking device in favor of a reduction of the actuating forces during locking for such a connector assembly is particularly advantageous. Furthermore, the wire elements can be conveniently made as a wire bending parts of spring steel wire.

Der Betätigungsgriff kann als L-förmiges Strangussprofil mit einem durchgehenden Langloch ausgebildet sein. So können aus einem Stück mit geringem Aufwand mehrere Griffe gesägt und in deren Enden Verrastungsfedem unverlierbar eingebacht werden.The actuating handle may be formed as an L-shaped extruded profile with a continuous slot. So can be sawn from one piece with little effort several handles and in the ends Verrastungsfedem be captivated.

Eine Verriegelungsvorrichtung (100) umfasst einen Betätigungsgriff (101) mit beidseitig daran angefügten Verriegelungselementen (102, 102'). Ein solches Verriegelungselement (102) ist als Einzelteil im ungewinkelten Zustand in Fig. 1a und im gewinkelten Zustand in Fig. 1b dargestellt.A locking device (100) comprises an actuating handle (101) with locking elements (102, 102 ') attached thereto on both sides. Such a locking element (102) is as an item in the angled state in Fig. 1a and in angled state in Fig. 1b shown.

Das Verriegelungselement (102) besteht aus einem einstückigen Federstahldraht und weist einen C-förmigen Schenkel (103) mit einem ersten Schenkelende (104) und einem zweiten Schenkelende (105) auf.The locking element (102) consists of a one-piece spring steel wire and has a C-shaped leg (103) with a first leg end (104) and a second leg end (105).

Am ersten Schenkelende (104) ist das Verriegelungselement zu einer offenen Öse (106) nach innen gebogen. An die Öse (106) schließt sich eine Ösenöffnung (107) an, in deren Verlauf das Verriegelungselement vom C-förmigen Schenkel (103) weggebogen ist. Im weiteren Verlauf besitzt das Verriegelungselement eine weitere Biegung, durch die das Verriegelungselement in einem ersten Endstück (108) den C-förmigen Schenkel (103) rechtwinklig kreuzt.At the first leg end (104), the locking element is bent inwardly toward an open eyelet (106). The eyelet (106) is adjoined by an eyelet opening (107), in the course of which the locking element is bent away from the C-shaped limb (103). In the further course possesses the Locking element another bend, through which the locking element in a first end piece (108) crosses the C-shaped leg (103) at right angles.

An dem zweiten Schenkelende (105) ist das Verriegelungselement kreissegmentförmig in einem geeigneten Krümmungsradius um 180° nach innen gebogen. Das Ende dieser Biegung bildet eine Aufgleitrundung (109). Im Anschluss an einen kurzen geradlinigen Abschnitt besitzt das Verriegelungselement eine Einbuchtung (110), die ebenfalls kreissegmentförmig verläuft. Anschließend an die Einbuchtung (110) besitzt das Verriegelungselement eine weitere Biegung, durch die es in einem zweiten Endstück (111) parallel zum ersten Endstück (108) verläuft und den C-förmigen Schenkel (103) rechtwinklig kreuzt.At the second leg end (105), the locking element is bent in a circle segment shape in a suitable radius of curvature by 180 ° inwards. The end of this bend forms a Aufgleitrundung (109). Following a short rectilinear section, the locking element has a recess (110), which likewise extends in the shape of a circle segment. Subsequent to the indentation (110), the locking element has a further bend, through which it runs in a second end piece (111) parallel to the first end piece (108) and crosses the C-shaped leg (103) at right angles.

Wie in der Fig. 1b dargestellt ist, sind die beiden parallel verlaufenden Endstücke (108, 111) rechtwinklig zu einer durch die C-Form gebildeten Ebene umgebogen und sind somit dazu geeignet, mit einer Seite des Betätigungsgriffs (101) verbunden zu werden.Like in the Fig. 1b 2, the two parallel end pieces (108, 111) are bent at right angles to a plane formed by the C-shape and are thus adapted to be connected to one side of the operating handle (101).

Weiterhin ist auch eine Variante vorgesehen, bei der die beiden Endstücke (108, 111) nicht umgebogen sind. Auch in dieser Variante sind die Endstücke dazu geeignet, mit einem entsprechend ausgeführten Betätigungsgriff verbunden zu werden.Furthermore, a variant is provided in which the two end pieces (108, 111) are not bent. Also in this variant, the end pieces are adapted to be connected to a correspondingly executed operating handle.

In der Fig.2 ist die Verriegelungsvorrichtung (100), bestehend aus einem Betätigungsgriff (101) mit zwei daran angefügten Verriegelungselementen (102, 102') dargestellt.In the Fig.2 is the locking device (100), consisting of an actuating handle (101) with two attached thereto locking elements (102, 102 ') shown.

In der Fig.3 ist ein Steckverbindergehäuse (400) mit der Verriegelungsvorrichtung (100) im unverriegelten Zustand dargestellt. Das Steckverbindergehäuse (400) besteht dabei aus einer ersten Steckverbindergehäusehälfte (200) mit zwei Lagerzapfen (201) und einer zweiten Steckverbindergehäusehälfte (300) mit zwei Arretierzapfen (301). Durch Anheben des Betätigungsgriffs (101) wird beim Kontakt des zweiten Schenkelendes (105) mit dem entsprechenden Arretierzapfen (301) das erste Endstück (108) vom Lagerzapfen (201) elastisch weggebogen und gleichzeitig wird das zweite Endstück (111) zu dem Arretierzapfen (301) elastisch hingebogen. Somit ist eine Anhebung der Aufgleitrundung (109) gewährleistet, wodurch diese beim Verriegelungsvorgang mit vergleichsweise geringem Kraftaufwand über den entsprechenden Arretierzapfen (301) gleiten kann.In the Figure 3 a connector housing (400) with the locking device (100) is shown in the unlocked state. The connector housing (400) consists of a first connector housing half (200) with two bearing pins (201) and a second connector housing half (300) with two locking pins (301). By lifting the operating handle (101), upon contact of the second leg end (105) with the corresponding locking pin (301), the first end piece (108) is elastically bent away from the bearing pin (201) and at the same time the second end piece (111) is bent elastically towards the locking pin (301). Thus, an increase of the Aufgleitrundung (109) is ensured, whereby they can slide during locking operation with relatively little effort on the corresponding locking pin (301).

In der Fig.4 ist ein in dieser Weise verriegeltes Steckverbindergehäuse (400) dargestellt.In the Figure 4 a connector housing (400) locked in this manner is shown.
