Titel: VERRIEGELUNGSEINRICHTUNG FÜR LEITUNGSVERBINDER Title: LOCKING DEVICE FOR LINE CONNECTORS
Die Erfindung betrifft eine Verriegelungseinrichtung für Leitungsverbinder, mit einem ersten Gehäuse und einem zweiten Gehäuse, die in einer Eingriffsrichtung gegeneinan der ansetzbar sind, einem Satz von elastischen Verriegelungslaschen, die durch Befesti gungsorgane an dem ersten Gehäuse gehalten und verrastend an Verriegelungsvorsprün- gen des zweiten Gehäuses verriegelbar sind, und mit einem in der Eingriffsrichtung auf den Gehäusen verschiebbaren Entriegelungsring, der Entriegelungs schrägen zum Über führen der Verriegelungslaschen in eine entriegelte Stellung aufweist. The invention relates to a locking device for line connectors, with a first housing and a second housing, which can be placed against one another in an engagement direction, a set of elastic locking tabs, which are held on the first housing by fastening elements and latching on locking projections on the second housing are locked, and with a displaceable in the engagement direction on the housing unlocking ring, the unlocking sloping lead to transfer the locking tabs into an unlocked position.
Solche Verriegelungseinrichtungen dienen beispielsweise zur Verrieglung von zueinan- der komplementären Steckverbindern, beispielsweise elektrischen Steckverbindern, die jeweils in einem der beiden Gehäuse aufgenommen sind, so dass dadurch, dass die bei den Gehäuse aneinander verriegelt werden, auch die Steckverbinder in ihrer Eingriffs stellung gehalten werden. Insbesondere befasst sich die Erfindung mit Verriegelungseinrichtungen für Verbinder, die relativ große Abmessungen, beispielsweise in der Größenordnung von mehreren Zentimetern aufweisen, so dass auch die zur Aufnahme der Verbinder dienenden Ge häuse entsprechend große Abmessungen haben müssen und ein relativ hohes Gewicht aufweisen. Da bei der Handhabung dieser Verbinder und der zugehörigen Gehäuse rela- tiv große Kräfte auftreten können, gelten für die Verriegelungseinrichtungen hohe Sta bilitätsanforderungen. Such locking devices are used, for example, to lock mutually complementary connectors, for example electrical connectors, which are each accommodated in one of the two housings, so that the fact that the two housings are locked together also holds the connectors in their engaged position. In particular, the invention relates to locking devices for connectors that have relatively large dimensions, for example of the order of several centimeters, so that the housing used to hold the connector must also have correspondingly large dimensions and be relatively heavy. Since relatively large forces can occur when handling these connectors and the associated housing, high stability requirements apply to the locking devices.
Aus EP 1 729377 Al ist eine Verriegelungseinrichtung der eingangs genannten Art be kannt, bei der die Befestigungsorgane an die Wand des ersten Gehäuses angeformt sind und Einsteckschlitze definieren, in welche die Befestigungslaschen eingesteckt werden können. Entsprechend werden auch die Verriegelungsvorsprünge des zweiten Gehäuses durch Anformungen an der Gehäusewand gebildet . Das Deutsche Patent- und Markenamt hat in der Prioritätsanmeldung zur vorliegenden Anmeldung den folgenden Stand der Technik recherchiert: DE 3624 678 Al, EP 1 729377 A1 discloses a locking device of the type mentioned at the outset, in which the fastening elements are formed onto the wall of the first housing and define insertion slots into which the fastening tabs can be inserted. Correspondingly, the locking projections of the second housing are also formed by moldings on the housing wall. The German Patent and Trademark Office has researched the following prior art in the priority application for the present application: DE 3624 678 A1,
DE 202006004 794 Ul, DE 1244499 A, US 6,030,244 A und EP 1 729377 Al. Aufgabe der Erfindung ist es, eine Verriegelungseinrichtung zu schaffen, die sich ratio nell in einer Vielzahl von Varianten für Verbinder mit unterschiedlichen Abmessungen und unterschiedlichen Stabilitätsanforderungen hersteilen lässt. DE 202006004 794 U1, DE 1244499 A, US Pat. No. 6,030,244 A and EP 1 729377 A1. The object of the invention is to create a locking device that can be manufactured rationally in a large number of variants for connectors with different dimensions and different stability requirements.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Befestigungsorgane und die Verriegelungsvorsprünge als Zapfen ausgebildet sind, die in Umfangswände der bei den Gehäuse eingelassen sind. According to the invention, this object is achieved in that the fastening elements and the locking projections are designed as pins which are embedded in the peripheral walls of the housing.
Bei dieser Verriegelungseinrichtung braucht somit keines der beiden Gehäuse beson dere Anformungen für die Verriegelungslaschen aufzuweisen. Damit können die Werk- zeugkosten für die Fertigung der Gehäuse beträchtlich reduziert werden. Für eine stabileIn this locking device, therefore, neither of the two housings needs to have special projections for the locking tabs. This means that the tool costs for manufacturing the housing can be significantly reduced. For a stable
Anbringung der Befestigungsorgane und der Verriegelungsvorsprünge genügt es, geeig nete Bohrungen in den Gehäusewänden auszubilden, in denen dann die zapfenförmigen Befestigungsorgane und Verriegelungsvorsprünge verankert werden, beispielsweise mittels Gewinde- oder Nietverbindungen. Die Anzahlen und Positionen der Verriege- lungslaschen lassen sich dann flexibel an die jeweilige Form und Größe der Gehäuse und die Stabilitätsanforderungen anpassen. Attachment of the fasteners and the locking projections, it is sufficient to form appro designated bores in the housing walls, in which the pin-shaped fasteners and locking projections are then anchored, for example by means of threaded or rivet connections. The number and position of the locking tabs can then be flexibly adapted to the respective shape and size of the housing and the stability requirements.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. In einer Ausführungsform werden die Befestigungsorgane und die Verriegelungsvor- Sprünge durch Nietzapfen gebildet. Die Verriegelungsvorsprünge können dann einfach durch Nietköpfe dieser Zapfen gebildet werden. Die Befestigungslaschen können bei spielsweise durch Federbleche gebildet werden, die jeweils ein Loch für den zur Befes tigung dienenden Nietzapfen aufweisen. In einer gegenüber dem Nietloch versetzten Position können diese Federbleche eine Auflaufschräge für den Verriegelungsvorsprung sowie ein weiteres Loch aufweisen, in das im verriegelten Zustand der Verriegelungs vorsprung eingreift. Wenn dann das erste Gehäuse an das zweite Gehäuse angesetzt wird, so laufen die Auflaufschrägen der Federbleche auf die Verriegelungsvor Sprünge auf und werden dadurch elastisch aufgeweitet, bis die Verriegelungsvorsprünge in den Öffnungen der Federbleche einrasten. Auf diese Weise wird eine zugfeste Verbindung zwischen den beiden Gehäusen geschaffen, die sich nur dadurch wieder lösen lässt, dass die Federbleche mit Hilfe der Entriegelungs schrägen des Entriegelungsrings von den Wänden des zweiten Gehäuses weggebogen werden, so dass sie die als Verriegelungs- vorsprünge dienenden Nietköpfe wieder frei geben. Die Auflaufschrägen der Federble che können zugleich als Gegenflächen für die Entriegelungs schrägen dienen. Advantageous refinements of the invention are specified in the dependent claims. In one embodiment, the fastening organs and the locking projections are formed by rivet pins. The locking projections can then simply be formed by rivet heads of these pins. The mounting brackets can be formed by spring plates, for example, each having a hole for the account used for fastening rivet pin. In a position offset from the rivet hole, these spring plates can have a run-on slope for the locking projection and a further hole into which the locking projection engages in the locked state. Then, when the first housing is attached to the second housing, the run-up bevels of the spring plates run onto the locking before jumps and are thereby elastically widened until the locking projections in the Snap in the openings of the spring plates. In this way, a strong connection is created between the two housings, which can only be released again by bending the spring plates away from the walls of the second housing using the unlocking bevels of the unlocking ring, so that they have the rivet heads serving as locking projections release again. The bevels of the Federble surface can also be used as mating surfaces for the unlocking bevels.
Im folgenden wird ein Ausführungsbeispiel anhand der Zeichnung näher erläutert. Es zeigen: In the following an embodiment is explained in more detail with reference to the drawing. Show it:
Fig. 1 einen axialen Schnitt durch zwei miteinander verriegelte Gehäuse einer erfindungsgemäßen Verriegelungseinrichtung; Fig. 2 die Verriegelungseinrichtung nach Fig. 1 im entriegelten Zustand; 1 shows an axial section through two interlocked housings of a locking device according to the invention; FIG. 2 shows the locking device according to FIG. 1 in the unlocked state;
Fig. 3 eine Frontansicht der beiden nach Entriegelung voneinander gelös ten Gehäuse; und Fig. 4 eine Seitenansicht der aneinander verriegelten Gehäuse. 3 shows a front view of the two housings that have been unlocked from one another; and FIG. 4 is a side view of the housings locked together.
In Fig. 1 sind in einem axialen Schnitt ein erstes Gehäuse 10 und ein zweites Gehäuse 12 gezeigt, die in einer Eingriffsrichtung A aneinander angesetzt und miteinander ver riegelt sind. Jedes der beiden Gehäuse 10, 12 dient zur Aufnahme einer von zwei kom- plementären Komponenten eines nicht gezeigten Steckverbinders, beispielsweise eines elektrischen Steckverbinders. Im Inneren weisen beide Gehäuse 10, 12 Einbauten 14, 16 auf, die zum Positionieren und Fixieren der Komponenten des Steckverbinders dienen. Das erste Gehäuse 10 weist außerdem in der Wand, die in Fig. 1 in der Innenansicht ge zeigt ist, eine Durchführung 18 für ein elektrisches Anschlusskabel auf. In Fig. 1, a first housing 10 and a second housing 12 are shown in an axial section, which are attached to each other in an engagement direction A and locked together ver. Each of the two housings 10, 12 serves to accommodate one of two complementary components of a plug connector, not shown, for example an electrical plug connector. Inside, both housings 10, 12 have internals 14, 16, which are used to position and fix the components of the connector. The first housing 10 also has in the wall, which is shown in FIG. 1 in the interior view, a passage 18 for an electrical connection cable.
In den beiden im Schnitt dargestellten Wänden des ersten Gehäuses 10 sind Griffmul den 20 gebildet. Als Beispiel kann angenommen werden, dass das Gehäuse in der Breite so dimensioniert ist, dass es gerade noch mit dem Daumen und den Fingern einer Hand umspannt werden kann. Die beiden Gehäuse 10, 12 können aus Kunststoff oder auch aus Metall hergestellt sein. In the two walls of the first housing 10 shown in section Griffmul are the 20 formed. As an example, it can be assumed that the housing in width is dimensioned in such a way that it can just about be clasped with the thumb and fingers of one hand. The two housings 10, 12 can be made of plastic or metal.
Das zweite Gehäuse 12 weist an seinem oberen Rand eine Dichtung 22 auf, auf die das erste Gehäuse 10 mit seinem unteren Rand aufgesetzt ist. In der Nähe seines unteren Randes weist das erste Gehäuse 10 in den beiden im Schnitt dargestellten Seitenwänden jeweils zwei Nietzapfen 24 auf, von denen jeweils nur einer sichtbar und im Schnitt dargestellt ist. Jeder Nietzapfen 24 durchgreift auf der Gehäuse außenseite ein Nietloch einer Verriegelungslasche 26, die im gezeigten Beispiel durch einen Streifen aus Federstahlblech gebildet wird. Ein gekröpfter oberer Rand der Verrie- gelungslasche greift in eine flache Mulde 28 ein, die in der Außenwand des ersten Ge häuses 10 gebildet ist. Dadurch wird die Verriegelungslasche 26 so positioniert, dass sie sich von dem Nietzapfen 24 aus vertikal nach unten erstreckt. Durch den Kopf des Nietzapfens 24 wird die Verriegelungslasche in fester Anlage an der Außenwand des Gehäuses 10 gehalten. Ein unterhalb des Nietzapfens 24 liegender Teil der Verriege- lungslasche ist von der Gehäusewand weg gebogen und läuft dann schräg nach unten auf die Außenfläche der Wand des zweiten Gehäuses 12 zu. In diesem schräg auf das zweite Gehäuse 12 zulaufenden Abschnitt hat die Verriegelungslasche ein Langloch 30, das von einem Verriegelungsvorsprung 32 des zweiten Gehäuses 12 durchgriffen wird. Bei diesem Verriegelungsvorsprung 32 handelt es sich um den Kopf eines weiteren Nietzapfens 34, der fest in die Umfangswand des zweiten Gehäuses 12 eingenietet ist. Unterhalb des Nietzapfens 34 bildet die Verriegelungslasche 26 eine von der Gehäuse wand abgespreizte Auflauf schräge 36. The second housing 12 has a seal 22 on its upper edge, onto which the first housing 10 is placed with its lower edge. In the vicinity of its lower edge, the first housing 10 has two rivet pins 24 in each of the two side walls shown in section, only one of which is visible and shown in section. Each rivet pin 24 passes through a rivet hole of a locking tab 26 on the outside of the housing, which in the example shown is formed by a strip of spring steel sheet. A cranked upper edge of the locking tab engages in a shallow depression 28 formed in the outer wall of the first housing 10 Ge. This positions the locking tab 26 so that it extends vertically downward from the rivet shank 24 . The locking tab is held firmly against the outer wall of the housing 10 by the head of the rivet pin 24 . A portion of the locking tab below the rivet pin 24 is bent away from the housing wall and then slopes downward toward the outer surface of the wall of the second housing 12 . In this section running obliquely towards the second housing 12, the locking tab has an elongated hole 30 through which a locking projection 32 of the second housing 12 passes. This locking projection 32 is the head of another rivet pin 34 which is firmly riveted into the peripheral wall of the second housing 12 . Below the rivet pin 34, the locking tab 26 forms a ramp 36 spread out from the housing wall.
Die beiden Gehäuse 10, 12 sind in Höhe der Dichtung 22 von einem Entriegelungsring 38 umgeben, der innenseitig für jede Verriegelungslasche eine Tasche 40 bildet, in der die Köpfe der Nietzapfen 24 und 34 sowie die Verriegelungslasche 26 aufgenommen sind. An seinem unteren Rand bildet der Entriegelungsring 38 eine Entriegelungs schräge 42, die sich in dem in Fig. 1 gezeigten Zustand etwas unterhalb der Auflauf schräge 36 der Verriegelungslasche befindet. Der Entriegelungsring 38 ist axial, also parallel zu der Eingriffsrichtung A verschiebbar am ersten Gehäuse 10 geführt. Der obere Rand der Tasche 40 bildet einen Anschlag für den Kopf des Nietzapfens 24, wodurch das Bewegungsspiel des Entriegelungsrings nach unten in Fig. 1 begrenzt wird. Weiter oberhalb weist der Entriegelungsring zwei auf gleicher Höhe liegende Vorsprünge 44 auf, die jeweils in eine der Mulden 28 ein- greifen und so das Bewegungs spiel des Verriegelungsrings nach oben begrenzen. The two housings 10, 12 are surrounded at the level of the seal 22 by an unlocking ring 38 which forms a pocket 40 on the inside for each locking tab, in which the heads of the rivet pins 24 and 34 and the locking tab 26 are received are. At its lower edge, the unlocking ring 38 forms an unlocking slant 42, which is in the state shown in Fig. 1 slightly below the casserole 36 of the locking tab. The unlocking ring 38 is guided on the first housing 10 so that it can be displaced axially, that is to say parallel to the engagement direction A. The upper edge of the pocket 40 forms a stop for the head of the rivet pin 24, thereby limiting the movement of the unlocking ring downwards in FIG. Further above, the unlocking ring has two projections 44 at the same height, which each engage in one of the depressions 28 and thus limit the upward movement of the locking ring.
Das erste Gehäuse 10 kann auf die folgende Weise auf dem zweiten Gehäuse 12 mon tiert und an diesem verriegelt werden. Zunächst wird Entriegelungsring 38 in seine un tere Endlage geschoben oder er fällt von selbst in die untere Endlage, wenn das erste Gehäuse 10 an seinem oberen Teil erfasst wird. Das Gehäuse 10 wird dann auf dieThe first housing 10 can be installed on and locked to the second housing 12 in the following manner. First, unlocking ring 38 is pushed into its lower end position or it falls by itself into the lower end position when the first housing 10 is grasped at its upper part. The housing 10 is then on the
Dichtung 22 aufgesetzt, wobei der Verriegelungsring 38 mit seinem unteren Teil über die Köpfe der Nietzapfen 34 hinweggeschoben wird. Die Verriegelungslaschen 26 lau fen mit ihren Auflaufschrägen 36 auf die Köpfe dieser Nietzapfen 34 auf und werden dadurch vorübergehend elastisch nach außen gespreizt. Sobald die unteren Ränder der Langlöcher 30 die Nietköpfe passiert haben, federn die Verriegelungslaschen elastisch in die in Fig. 1 gezeigte Stellung zurück, und die Verriegelung ist hergestellt. Die Teile des Entriegelungsrings 38, die den Boden der Taschen 40 bilden, verhindern, dass die Verriegelungslaschen 26 elastisch gespreizt werden und sich von den Verriegelungsvor- sprüngen 32 lösen. Seal 22 placed, wherein the locking ring 38 is pushed away with its lower part over the heads of the rivet pins 34. The locking tabs 26 lau fen with their bevels 36 on the heads of these rivet pins 34 and are thereby temporarily elastically spread outwards. As soon as the lower edges of the elongated holes 30 have passed the rivet heads, the locking tabs spring back elastically into the position shown in FIG. 1 and the locking is established. The portions of the unlocking ring 38 that form the bottom of the pockets 40 prevent the locking tabs 26 from elastically spreading and disengaging from the locking projections 32.
Wenn die Verriegelung gelöst werden soll, so wird der Entriegelungsring 38 nach oben in die in Fig. 2 gezeigte Position gezogen. Dabei gleiten die Entriegelungsschrägen 42 auf die nach außen gebogenen unteren Enden der Verriegelungslaschen 26 auf und be wirken deren Spreizung. Da sich der Verriegelungsring 38 insgesamt nach oben bewegt hat, können die Verriegelungslaschen 26 so weit gespreizt werden, bis der Teil, der das Langloch 30 bildet, am Boden der Tasche 40 anliegt und der Verriegelungsvor sprung 32 aus dem Langloch ausgetreten ist. Der Verriegelungsring 38 erreicht dabei seine obere Endlage. Wenn er weiter nach oben gezogen wird, so wird folglich das erste Ge häuse 10 von dem zweiten Gehäuse 12 abgezogen. Im weiteren Verlauf dieser Abzugs bewegung bewegen sich die Teile des Entriegelungsrings, die die Entriegelungsschrä gen 42 bilden, aufwärts an den Verriegelungsvorsprüngen 32 vorbei, bis schließlich auch der Verriegelungsring 38 vollständig von dem zweiten Gehäuse freigekommen ist. Sobald der Entriegelungsring losgelassen wird, sorgen die Schwerkraft und die Rückstellkräfte der Verriegelungslaschen 26 dafür, dass der Entriegelungsring relativ zum ersten Gehäuse 10 wieder in die Ausgangsstellung nach Fig. 1 zurückkehrt. Fig. 3 zeigt eine Ansicht, in der die Gehäuse 10, 12 ganz voneinander gelöst sind, der Entriegelungsring 38 sich aber noch in seiner angehobenen Position relativ zum Ge häuse 10 befindet. In dieser Ansicht ist zu erkennen, dass der Entriegelungsring 38 längs einer Teilungsnaht 46 in zwei miteinander verrastete Halbschalen unterteilt ist. Das untere Gehäuse 12 hat an seinem unteren Rand auf der Vorderseite und auf der Rückseite einen Anschlussflansch 48, der den Anbau an ein nicht gezeigtes weiteres Bauteil ermöglicht. When the latch is to be released, the release ring 38 is pulled up to the position shown in FIG. The unlocking bevels 42 slide onto the outwardly bent lower ends of the locking tabs 26 and act to spread them. Since the locking ring 38 has moved upwards overall, the locking tabs 26 can be spread apart until the part that forms the slot 30 rests against the bottom of the pocket 40 and the locking before jump 32 has emerged from the slot. The locking ring 38 reaches its upper end position. Consequently, if it is pulled further upwards, the first housing 10 is deducted from the second housing 12 . In the further course of this deduction movement move the parts of the unlocking ring, which form the Entriegelungsschrä gene 42, upwards past the locking projections 32 until finally the locking ring 38 is completely released from the second housing. As soon as the unlocking ring is released, the force of gravity and the restoring forces of the locking tabs 26 ensure that the unlocking ring returns to the starting position shown in FIG. 1 relative to the first housing 10 . Fig. 3 shows a view in which the housings 10, 12 are completely detached from each other, but the unlocking ring 38 is still in its raised position relative to the housing 10 Ge. In this view it can be seen that the unlocking ring 38 is subdivided along a dividing seam 46 into two half-shells which are latched to one another. The lower housing 12 has a connecting flange 48 on its lower edge on the front and on the back, which allows attachment to a further component, not shown.
Fig. 4 zeigt eine Seitenansicht der Gehäuse 10, 12 im verriegelten Zustand. Die Seiten wände des Gehäuses 10, von denen eine in dieser Ansicht teilweise sichtbar ist, haben zwei Mulden 28, in denen jeweils einer der Vorsprünge 40 geführt ist. Die Vorsprünge 44 befinden sich an einem dreieckigen Fortsatz, der den betreffenden Schenkel des Ent riegelungsrings 38 nach oben verlängert. Am unteren Rand dieses Schenkels sind zwei Sätze von Entriegelungsschrägen 42 gebildet, je ein Satz für jede der beiden Verriege lungslaschen, die sich auf dieser Seite des Gehäuses 10 befinden. In der Mitte dieses Schenkels des Entriegelungsrings ist eine Griffmulde 50 gebildet, die das Erfassen und Verstellen des Entriegelungsrings erleichtert. Fig. 4 shows a side view of the housing 10, 12 in the locked state. The side walls of the housing 10, one of which is partially visible in this view, have two troughs 28, in each of which one of the projections 40 is guided. The projections 44 are located on a triangular extension that extends the relevant leg of the unlocking ring 38 upwards. At the bottom of this leg two sets of Entriegelungsschrägen 42 are formed, one set for each of the two Verriege development tabs that are located on this side of the housing 10. A recessed grip 50 is formed in the middle of this leg of the unlocking ring, which makes it easier to grasp and adjust the unlocking ring.
