Description

Die vorliegende Erfindung betrifft ein Sekundärverriegelungsmittel gemäß dem Oberbegriff von Anspruch 1 sowie ein Steckverbindergehäuse mit einem Sekundärverriegelungsmittel gemäß Anspruch 6.The present invention relates to a secondary locking means according to the preamble of claim 1 and a connector housing having a secondary locking means according to claim 6.

Im Gebiet der elektrischen und elektronischen Steckverbinder ist es üblich, die Kontaktträger in einem Steckverbindergehäuse unterzubringen. Dabei werden typischerweise Stift- und Buchsengehäuse oder allgemein erstes Gehäuseteil und zweites Gehäuseteil miteinander mechanisch verbunden.In the field of electrical and electronic connectors, it is common to accommodate the contact carriers in a connector housing. Typically pin and socket housing or generally first housing part and second housing part are mechanically connected to each other.

Darüber hinaus ist es üblich, neben dem reinen Zusammenstecken der Steckverbindergehäuse eine mechanische Verrastung oder Verriegelung vorzusehen, dass der Steckverbinder nach bestimmungsgemäßem Stecken nicht mehr unbeabsichtigt getrennt werden kann.In addition, it is customary to provide a mechanical locking or locking in addition to the pure mating of the connector housing, that the connector can not be accidentally disconnected after proper insertion.

Im Stand der Technik wird zwischen Rundsteckverbindem und Rechtecksteckverbindem unterschieden.In the prior art, a distinction is made between circular connectors and rectangular connectors.

Die vorliegende Erfindung betrifft eine Sekundärverriegelung für Rechtecksteckverbinder mit einem Verriegelungsbügel.The present invention relates to a secondary latch for rectangular connector with a locking bracket.

Im Stand der Technik sind Rechtecksteckverbinder mit Verriegelungsbügel bekannt. Dabei wird ein erstes Steckverbindergehäuse an einem zweiten Steckverbindergehäuse mittels eines bewegbaren Verriegelungsbügels mechanisch arretiert. Als Gegenarretiermittel dient in der Regel ein Arretierbolzen.In the prior art rectangular connector with locking bracket are known. In this case, a first connector housing is mechanically locked to a second connector housing by means of a movable locking bracket. As Gegenarretiermittel usually serves a locking pin.

Allerdings ist von Nachteil, dass diese Steckverbinder im eingebauten Zustand und somit auch im Betriebszustand entgegen ihrer Bestimmung lösbar miteinander verbunden sind und daher unter Last getrennt werden können.However, it is disadvantageous that these plug connectors are detachably connected to one another in the installed state and thus also in the operating state contrary to their determination and can therefore be disconnected under load.

Grundsätzlich darf ein Steckverbinder nicht unter Last gezogen werden. Unter Last darf nur eine Steckvorrichtung gesteckt oder getrennt werden. Eine Steckvorrichtung hat gegenüber einem Steckverbinder andere Bemessungswerte und ist für das Trennen unter Last ausgelegt.Basically, a connector must not be pulled under load. Under load, only one plug-in device may be inserted or disconnected. A plug-in device has different rated values compared to a plug-in connector and is designed for disconnection under load.

Ganz allgemein schreibt auch die IEC 61984 als Internationaler Standard für Steckverbinder vor, dass Steckverbinder unter Last nicht getrennt werden dürfen.In general, IEC 61984, as the international standard for connectors, states that connectors must not be disconnected under load.

Bei den im Markt befindlichen Steckverbindern kann dies jedoch nur dadurch gewährleistet werden, dass sich die Anwender an diese Vorschrift letztendlich halten.For the connectors on the market, however, this can only be ensured by the fact that the users ultimately adhere to this rule.

In der Praxis hat sich aber gezeigt, dass trotz des Verbotes des Trennens solcher Steckverbinder, diese regelmäßig getrennt werden.In practice, however, it has been shown that despite the prohibition of disconnecting such connectors, they are regularly disconnected.

Ganz allgemein formuliert ist daher Aufgabe der vorliegenden Erfindung, ein Lösen eines Steckverbinders ohne Werkzeug zu verhindern.In general terms, therefore, the object of the present invention is to prevent loosening of a connector without tools.

Die Lösung dieser Aufgabe ist es, ein Sekundärverriegelungsmittel für vorbesagte Steckverbinder bereitzustellen, welches wahlweise nachträglich oder zusammen mit neu hergestellten Steckverbindern bereitgestellt wird und das verhindert, dass die Verriegelungsbügel der Steckverbinder geöffnet werden können.The solution to this problem is to provide a secondary locking means for said connectors, which is optionally provided subsequently or together with newly manufactured connectors and which prevents the locking brackets of the connectors can be opened.

Die Erfindung wird mittels eines Sekundärverriegelungsmittels gemäß den Merkmalen von Anspruch 1 gelöst.The invention is achieved by means of a secondary locking means according to the features of claim 1.

Erfindungsgentäß wird auch ein Steckverbindergehäuse gemäß den Merkmalen von Anspruch 6 vorgeschlagen.Erfindungsgentäß also a connector housing according to the features of claim 6 is proposed.

Das erfindungsgemäße Sekundärverriegelungsmittel kann nur mittels eines Werkzeuges oder jedenfalls nur mittels geplanten, bewussten, bestimmungsgemäßen Lösens entfernt werden.The secondary locking means according to the invention can be removed only by means of a tool or at least only by means of planned, conscious, intended loosening.

Das Sekundärverriegelungsmittel ist dabei vorzugsweise aus einem Federblech ausgebildet mit einer Öffnung zum Befestigen des Federbleches am Verriegelungsbügel eines Steckverbindergehäuses, sowie einer weiteren Öffnung für den gehäuseseitigen Befestigungsbolzen und einer dazu benachbarten Öffnung, die derart am Federblech angeordnet ist, dass das Federblech mittels eines lösbaren Verbindungsmittels am gehäuseseitigen Befestigungsbolzen mit seiner weiteren Öffnung festgelegt werden kann und dadurch ein Lösen des Verriegelungsbügels am Bolzen verhindert wird.The secondary locking means is preferably formed of a spring plate with an opening for securing the spring plate on the locking bracket of a connector housing, and a further opening for the housing-side fastening bolt and an adjacent thereto opening, which is arranged on the spring plate, that the spring plate by means of a releasable connection means on housing-side fastening bolt can be set with its other opening and thereby a release of the locking bracket is prevented on the bolt.

Anders ausgedrückt verhindert das Sekundärverriegelungsmittel mit seinen Öffnungen, dass das Primärverriegelungsmittel gelöst werden kann.In other words, the secondary locking means with its openings prevents the primary locking means from being released.

In einer materialsparenden, vorteilhaften Ausgestaltung wird das Federblech als ein zungenförmig länglich ausgebildetes Federblech hergestellt. Im einfachsten Falle als eine Federzunge mit drei Löchern. An dem ersten Loch kann das Federblech am Verriegelungsbügel oder allgemein an der Primärverriegelung des Steckverbindergehäuses befestigt werden, wobei das an dem anderen Ende der Federzunge angeordnete Loch bzw. die dort angeordnete Öffnung zum Festlegen am gehäuseseitigen Befesügungsbolzen für den Verriegelungsbügel dient.In a material-saving, advantageous embodiment, the spring plate is produced as a tongue-shaped elongated spring plate. In the simplest case as a spring tongue with three holes. At the first hole, the spring plate may be secured to the locking bracket or generally to the primary latch of the connector housing, with the hole or aperture disposed thereon at the other end of the spring tongue serving for attachment to the housing-side mounting bolt for the locking bracket.

Insofern nutzt das Sekundärverriegelungsmittel erfindungsgemäß als Gegenrastmittel, das gleiche Gegenrastmittel wie das Primärverriegelungsmittel und zwar den Befestigungsbolzen.In this respect uses the secondary locking means according to the invention as a counter-locking means, the same counter-locking means as the primary locking means and that the fastening bolt.

In einer einfachsten Ausführungsform hat der Verriegelungsbügel einen Verriegelungsarm mit einer Rastnase, der sich am Befestigungsbolzen des korrespondierenden Gehäuses verhakt. An diesem Befestigungsbolzen wird die erfindungsgemäße Sekundärverriegelung arretiert. Um ein manuelles Öffnen des Sekundärverriegelungsmittels zu verhindern, verfügt dieses über die zuvor besagte dritte Öffnung, die in vorteilhafter Weise zwischen der ersten und der zweiten Öffnung angeordnet ist. Diese Öffnung dient dem Befestigen des Sekundärvemegelungsmittel am Primärverriegelungsmittel.In a simplest embodiment, the locking bracket has a locking arm with a latching nose, which hooks on the fastening bolt of the corresponding housing. At this fastening bolt secondary locking of the invention is locked. In order to prevent a manual opening of the secondary locking means, this has the aforementioned third opening, which is advantageously arranged between the first and the second opening. This opening serves to attach the secondary control means to the primary locking means.

In einer vorteilhaften Ausgestaltung wird im Primärverriegelungsmittel bzw. im Verriegelungsbügel eine Gewindeöffnung angebracht, so dass das Sekundärverriegelungsmittel mit seiner dafür vorgesehenen Öffnung am Verriegelungsbügel in seiner bestimmungsgemäßen Position, vorzugsweise mittels einer Schraube, festgelegt werden kann.In an advantageous embodiment, a threaded opening is mounted in the primary locking means or in the locking bracket, so that the secondary locking means can be fixed with its designated opening on the locking bracket in its intended position, preferably by means of a screw.

Da in dieser bestimmungsgemäßen Position das Sekundärverriegelungsmittel mit einer seiner Öffnungen den Befestigungsbolzen umschließt bzw. der Befestigungsbolzen durch diese Öffnung zumindest teilweise hindurchragt, lässt sich der Verriegelungsbügel in dieser Stellung nicht öffnen.Since in this intended position the secondary locking means encloses the fastening bolt with one of its openings or the fastening bolt at least partially protrudes through this opening, the locking bracket can not be opened in this position.

Wird als Arretiermittel für das Festlegen des Sekundärverriegelungsmittels am Primärverriegelungsmittel mit einer Schraube oder einem Verriegelungsmittel verbunden, welches nur mit einem Werkzeug lösbar ist, so erhält man Im Ergebnis ein Sekundärverriegelungsmittel, welches nicht werkzeuglos lösbar ist und damit einen nicht werkzeuglos lösbaren Steckverbinder bzw. ein nicht werkzeuglos lösbares Steckverbindergehäuse.Is connected as a locking means for fixing the secondary locking means on the primary locking means with a screw or a locking means which is solvable only with a tool, we obtain as a result, a secondary locking means which is not tool-free solvable and thus a not releasable without tools connector or not Tool-free detachable connector housing.

Ferner sieht die Erfindung ein Steckverbindergehäuse mit einem ersten Gehäuseteil und einem zweiten Gehäuseteil vor, wobei am ersten Gehäuseteil ein Befestigungsbolzen angebracht ist und am zweiten Gehäuseteil ein Befestigungsbügel oder allgemein ein Primärverriegelungsmittel, welches am Befestigungsbolzen verrastbar ist, um die beiden Steckverbindergehäuseteile mechanisch miteinander zu verriegeln bzw. zu verrasten.Furthermore, the invention provides a connector housing with a first housing part and a second housing part, wherein a fastening bolt is attached to the first housing part and on the second housing part a mounting bracket or generally a primary locking means which can be latched to the fastening bolt to mechanically lock the two connector housing parts together or to latch.

Dieses erfindungsgemäße Steckverbindergehäuse verfügt an seinem Primärverriegelungsmittel Ober eine, wie zuvor beschriebene Sekundärverriegelung bzw. ein wie zuvor beschriebenes Sekundärverriegelungsmittel, welches in einer einfachsten und vorteilhaften Ausführungsform, mittels einer Niete, am Primärverriegelungsmittel drehbar befestigt ist.This connector housing according to the invention has at its primary locking means upper as described above secondary locking or as described above secondary locking means which is rotatably mounted in a simple and advantageous embodiment, by means of a rivet on the primary locking means.

Dabei weist das Sekundärverriegelungsmittel drei Öffnungen auf, die mit drei Öffnungen am Primärverriegelungsmittel in Deckung zu bringen sind. Die eine endseitige Öffnung ist an der dazu korrespondierenden Befestigungsöffnung am Bügel, vorzugsweise mittels einer Niete, drehbar gelagert.In this case, the secondary locking means has three openings which are to be brought into coincidence with three openings on the primary locking means. The one end opening is rotatably mounted on the corresponding attachment opening on the bracket, preferably by means of a rivet.

Durch Verdrehen des Sekundärverriegelungsmittels in die bestimmungsgemäße Position lässt sich die zweite Öffnung am Sekundärverriegelungsmittel in eine korrespondierende Lage zur zweiten Öffnung am Primärverriegelungsmittel bringen. In dieser Position durchdringt ein Teil, vorzugsweise das eine Ende des Befestigungsbolzens, die dritte Öffnung im Sekundärverriegelungsmittel, so dass dieses gegen Verdrehen gesichert ist.By rotating the secondary locking means to the intended position, the second opening on the secondary locking means can be brought into a corresponding position to the second opening on the primary locking means. In this position, a part, preferably the one end of the fastening bolt, penetrates the third opening in the secondary locking means so that it is secured against twisting.

In einer besonders bevorzugten Ausgestaltung liegen damit auf einer geometrischen Achse die drei zuvor genannten Löcher bzw. Befestigungspunkte.In a particularly preferred embodiment are thus on a geometric axis, the three aforementioned holes or attachment points.

Die Fig. 1 zeigt in seiner einfachsten Form ein erfindungsgemäßes Sekundärverriegelungsmittel 12 mit drei Öffnungen 14, 15, 16. Das in Fig.1 gezeigte Sekundärverriegelungsmittel 12 ist als ein Federblech 20 ausgebildet, welches eine längliche Zungenform aufweist. Das Federblech 20 lässt sich dabei senkrecht zur Projektionsachse zu der Ansicht in Fig. 1 federnd auslenken. Dadurch lässt sich das Federblech 20 bei Befestigung, in der Fig. 1 linken Öffnung 16, um einen Winkel α aus der Plattebene auslenken, was zur Montage des Sekundärverriegelungsmittels 12 notwendig ist.The Fig. 1 shows in its simplest form a secondary locking means 12 according to the invention with three openings 14, 15, 16. Das in Fig.1 shown secondary locking means 12 is formed as a spring plate 20 having an elongated tongue shape. The spring plate 20 can be perpendicular to the projection axis to the view in Fig. 1 deflect resiliently. This allows the spring plate 20 when mounting, in the Fig. 1 left opening 16 to deflect an angle α from the plate plane, which is necessary for mounting the secondary locking means 12.

Die Öffnung 16 dient dabei der Befestigung des Sekundärverriegelungsmittels 12 an einem Primärverriegelungsmittel 7, allgemein an einer Steckverbinderverriegelung 7.The opening 16 serves to fasten the secondary locking means 12 to a primary locking means 7, generally to a connector lock 7.

Die Öffnung 14 dient der Befestigung und damit Arretierung des Primärverriegelungsmittels 7 an einem Befestigungsbolzen 7a, wie dies aus Fig. 2 ersichtlich ist.The opening 14 is used for fastening and thus locking of the primary locking means 7 on a fastening bolt 7 a, as is apparent from Fig. 2 is apparent.

Die Wirkungsweise des erfindungsgemäßen Sekundärverriegelungsmittels 12 lässt sich am einfachsten anhand der Fig. 2 erläutern.The mode of operation of the secondary locking means 12 according to the invention can be most easily determined on the basis of Fig. 2 explain.

In Fig. 2 ist ein Steckverbindergehäuse 1 gezeigt, welches aus einem ersten Gehäuseteil 2 und einem zweiten Gehäuseteil 3 besteht.In Fig. 2 a connector housing 1 is shown, which consists of a first housing part 2 and a second housing part 3.

Das erste Gehäuseteil 2 verfügt über einen seitlichen Kabelausgang 4, wobei das zweite Gehäuseteil 3 als Anschlussgehäuse ausgebildet ist und an dessen unterem Ende sich ein Anschlussflansch 5 für eine Gehäusewand befindet.The first housing part 2 has a lateral cable outlet 4, wherein the second housing part 3 is designed as a connection housing and at the lower end there is a connection flange 5 for a housing wall.

Die beiden Gehäuseteile werden mittels einer Primärverriegelung 7 bzw. allgemein einer Steckverbinderverriegelung 7 miteinander verrastet bzw. verriegelt. Die Steckverbinderverriegelung 7 besteht in ihrer einfachsten Ausführungsform, wie in Fig. 2 gezeigt, aus einem Verriegelungsbügel 7a, welcher schwenkbar am Drehlager 30 des zweiten Gehäuseteils 3 befestigt ist. Dadurch lässt sich der Verriegelungsbügel von einem Öffnungs- in einen Verriegelungszustand überführen, in dem dieser um das Drehlager 30 verschwenkt wird. Zur Verriegelung des Verriegelungsbügels 7a verfügt das erste Gehäuse über ein Befestigungsbolzen 7b, an dem sich mit Vorteil ein Verriegelungsarm 9 des Verriegelungsbügels 7a verhaken kann. Dies kann insbesondere dadurch bewerkstelligt werden, dass der Verriegelungsarm 9 über eine Rastnase 10 verfügt, die sich am Befestigungsbolzen 7b verhaken kann. Der Verriegelungsbügel 7a wird mit einer nicht dargestellten Rückstellfeder am Drehlager 30 angebracht.The two housing parts are latched or locked together by means of a primary lock 7 or generally a connector lock 7. The connector lock 7 is in its simplest embodiment, as in Fig. 2 shown, from a locking bracket 7a, which is pivotally mounted on the pivot bearing 30 of the second housing part 3. As a result, the locking bracket can be transferred from an opening to a locking state in which it is pivoted about the pivot bearing 30. For locking the locking bracket 7a, the first housing has a fastening bolt 7b, on which a locking arm 9 of the locking bracket 7a can interlock advantageously. This can be accomplished, in particular, by virtue of the fact that the locking arm 9 has a latching lug 10 which can catch on the fastening bolt 7b. The locking bracket 7a is attached to the pivot bearing 30 with a return spring, not shown.

Wie in Fig. 2 am linken Verriegelungsbügel 7a ersichtlich, ist ein Sekundärverriegelungsmittel, gemäß Fig. 1, mit einem Verbindungsmittel 13 am Verriegelungsbügel 7a befestigt. Sofern das Arretiermittel 7 bzw. wie in Fig. 2 und Fig. 3 gezeigt, die Schraube 17 nicht am Verriegelungsbügel 7a in einem dort befindliches Montageloch bzw. einer dort befindliche Gewindeöffnung befestigt ist, lässt sich das Sekundärverriegelungsmittel 12 federnd aus der Zeichenebene heraus ausfedern und um die Öffnung 16 und damit das Verbindungsmittel 13 drehend verschieben.As in Fig. 2 on the left locking bracket 7a, is a secondary locking means, according to Fig. 1 , fastened with a connecting means 13 on the locking bracket 7a. If the locking means 7 or as in Fig. 2 and Fig. 3 shown, the screw 17 is not attached to the locking bracket 7a located there in a mounting hole or a threaded opening located there, the secondary locking means 12 resiliently aussprung out of the plane and around the opening 16 and thus the connecting means 13 rotate.

Auf diese Art und Weise lässt sich das Sekundärverriegelungsmittel 12 in seine bestimmungsgemäße Position, um das Verbindungsmittel 13 verdrehen und entgegen der ausgelenkten Federrichtung mit seiner Öffnung 14 über das Ende des Befestigungsbolzens 7b einrasten.In this way, the secondary locking means 12 can be in its intended position to rotate the connecting means 13 and engage against the deflected spring direction with its opening 14 via the end of the fastening bolt 7b.

In diesem Zustand lässt sich bereits der Verriegelungsbügel 7a nicht mehr öffnen. Zur Sicherung des Sekunärverriegelungsmittels 12 am Verriegelungsbügel 7a kann dieser mittels einer Schraube 17 am Verriegelungsbügel 7a festgeschraubt bzw. arretiert werden.In this state, the locking bracket 7a can not be opened. To secure the Sekunärverriegelungsmittels 12 on the locking bracket 7a this can be screwed or locked by means of a screw 17 on the locking bracket 7a.

Dieser entspricht dem in Fig. 2 gezeigten Zustand am linken Verriegetungsbügel 7a. In diesem Zustand lässt sich der Verriegelungsbügel 7a nur mittels eines Schraubwerkzeuges öffnen und ein versehentliches Öffnen der beiden Gehäuseteile wird verhindert.This corresponds to the in Fig. 2 shown state on the left Verriegtungsbügel 7a. In this state, the locking bracket 7a can be opened only by means of a screwing tool and accidental opening of the two housing parts is prevented.

Fig. 3 zeigt eine Unteransicht gemäß Fig. 2, bei dem eine Schraube 17 das Federblech 20 und damit das Sekundärverriegelungsmittel 12 am Verriegelungsbügel 7a festlegt. In der in Fig. 3 gezeigten Ansicht ist lediglich ein Verriegelungsbügel 7a mit einem Sekundärverriegelungsmittel 12 versehen. Fig. 3 shows a bottom view according to Fig. 2 in which a screw 17 fixes the spring plate 20 and thus the secondary locking means 12 on the locking bracket 7a. In the in Fig. 3 As shown, only one locking bracket 7a is provided with a secondary locking means 12.
