Der Erfindung liegt daher die Aufgabe zugrunde, eine weitere Art von  The invention is therefore based on the object, a further type of
Steckverbinder vorzustellen, um die Vielfalt derartiger Steckverbinder mit Verriegelungsmechanismen zu erweitern. Dabei soll der Steckverbinder möglichst wenig mechanische Einzelteile aufweisen und so die Ausfallsicherheit und Fehlerwahrscheinlichkeit der Vorrichtung verringert werden. To introduce connectors to expand the variety of such connectors with locking mechanisms. The connector should have as few mechanical items as possible and so the reliability and probability of failure of the device can be reduced.
Die Aufgabe wird durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. The object is solved by the characterizing features of independent claim 1. Advantageous embodiments of the invention are specified in the subclaims.
Bei der Erfindung handelt es sich um einen Steckverbinder zur Kontaktierung mit einem Gegensteckverbinder. Vorzugsweise ist der Steckverbinder zur Verbindung und Kontaktierung mit einem Stecksockel, einem sogenannten Receptacle vorgesehen. Dabei ist das Receptacle als passives Bauteil ausgestaltet an welchem der erfindungsgemäße Steckverbinder verrasten kann. In the invention is a connector for contacting with a mating connector. Preferably, the connector for connection and contacting with a socket, a so-called Receptacle is provided. In this case, the receptacle is designed as a passive component to which the connector according to the invention can latch.
Der Steckverbinder weist einen Grundkörper auf, welcher an einer Seite ein Steckgesicht bildet. Das Steckgesicht ist zur Kontaktierung mit dem Receptacle ausgelegt und bildet die Art / Sorte des Steckverbinders. Diese kann je nach Ausführung unterschiedlich ausgebildet sein und sich in Art, Größe und Anzahl der Kontakte unterscheiden. Am Grundkörper ist ein Betätigungsmittel angeordnet. Das Betätigungsmittel umschließt den Grundkörper vorzugsweise und ist entlang des Grundkörpers um einen definierten Weg verschiebbar. Der Steckverbinder weist zudem zumindest einen Rastarm auf, sowie einen im Grundkörper angeordneten Kontaktträger. Der Kontaktträger und der The connector has a base body, which forms a mating face on one side. The mating face is designed to make contact with the receptacle and forms the type / type of connector. This can be designed differently depending on the design and differ in the type, size and number of contacts. On the main body an actuating means is arranged. The actuating means preferably surrounds the base body and is displaceable along the base body by a defined path. The connector also has at least one latching arm, as well as arranged in the body contact carrier. The contact carrier and the
Grundkörper können je nach Ausgestaltung auch einteilig ausgebildet sein und aus einem Bauteil bestehen. Basic body can also be formed in one piece depending on the configuration and consist of a component.
Der zumindest eine Rastarm ist aus einem mechanisch flexiblen Material gebildet und kann ebenfalls mit dem Grundkörper einteilig ausgebildet sein. Aber auch eine Ausbildung als separates Bauteil, welches am Grundkörper angebracht ist, umfasst die Erfindung. Durch die Flexibilität des Rastarms kann dieser eine Schwenkbewegung ausführen. Dabei bildet der Rastarm ein freies Ende, welches vom Grundkörper weggeschwenkt und zum Grundkörper hin geschwenkt werden kann. Die Schwenkbewegung des Rastarms ist The at least one latching arm is formed of a mechanically flexible material and may also be integrally formed with the base body. But also a training as a separate component, which is attached to the body, includes the invention. Due to the flexibility of the latching arm this can perform a pivoting movement. In this case, the latching arm forms a free end, which can be pivoted away from the base body and pivoted toward the base body. The pivoting movement of the latching arm is
vorzugsweise radial ausgelegt. D.h. dass bei beispielsweise einem preferably designed radially. That that at, for example, a
Rundsteckverbinder die Schwenkbewegung weg von der Symmetrieachse des Steckverbinders ist. Das freie Ende des Rastarms ist in Richtung des Steckgesichts des Circular connector is the pivoting movement away from the axis of symmetry of the connector. The free end of the latching arm is in the direction of the mating face of the
Steckverbinders ausgerichtet. So kann der Rastarm mit einem Receptacle verrasten, welcher in den Bereich des Steckgesichts eingeführt wird. Der zumindest eine Rastarm dient so zur mechanischen Verrastung des Aligned connector. Thus, the locking arm can lock with a Receptacle, which is inserted into the region of the mating face. The at least one latching arm thus serves for the mechanical latching of the
Steckverbinders mit dem Receptacle. Vorzugsweise sind am Steckverbinder zumindest drei Rastarme vorgesehen. Gerade bei Rundsteckverbindern ist die Anordnung von drei Rastarmen über den Umfang besonders vorteilhaft, da so eine besonders gleichmäßige Kraftverteilung gewährleistet wird. Aber auch sind Ausführung mit zwei, vier, fünf oder mehr Rastarm denkbar und je nach Connector with the Receptacle. Preferably, at least three locking arms are provided on the connector. Especially with circular connectors, the arrangement of three locking arms over the circumference is particularly advantageous because a particularly uniform force distribution is guaranteed. But also execution with two, four, five or more locking arm are conceivable and depending on
Anwendung zweckmäßig. Application expedient.
Erfindungsgemäß weist der Steckverbinder zumindest einen auf. Der Federarm ist dabei parallel zum Rastarm ausgerichtet und liegt an diesem an. Dabei kann der Federarm über eine bestimmte Länge am Rastarm anliegen oder nur punktuell den Rastarm berühren. Der Federarm ist vorzugsweise in According to the invention, the connector has at least one. The spring arm is aligned parallel to the locking arm and is applied to this. In this case, the spring arm rest over a certain length on the latching arm or only selectively touch the latching arm. The spring arm is preferably in
Schwenkrichtung am Rastarm anliegend. Durch den Federarm, welcher am Rastarm anliegt, wird die Federkraft des Rastarms erhöht. So hat der Rastarm durch seine Materialeigenschaften eine spezifische Federkonstante aus welcher sich eine Federkraft bei einer Schwenkbewegung ergibt. Durch den am Rastarm anliegenden Federarm wird die Federkraft um die Federkraft des Federarms erhöht, wenn der Rastarm in Richtung des Federarms schwenk und diesen mit schwenkt. Swivel direction fitting to the latching arm. By the spring arm, which rests on the latching arm, the spring force of the latching arm is increased. Thus, the locking arm has a specific spring constant due to its material properties, which results in a spring force during a pivoting movement. By the voltage applied to the latch arm spring arm, the spring force is increased by the spring force of the spring arm, when the latch arm in the direction of the spring arm pivots and this pivots.
Der Federarm ist mit dem Betätigungsmittel mechanisch verbunden. Eine spezielle Ausführungsform sieht vor, den Federarm einteilig mit dem The spring arm is mechanically connected to the actuating means. A special embodiment provides, the spring arm in one piece with the
Betätigungsmittel auszubilden. Durch die mechanische Verbindung von Form actuating means. Due to the mechanical connection of
Federarm und Betätigungsmittel kann der Federarm ebenfalls wie das Spring arm and actuator, the spring arm can also like that
Betätigungsmittel entlang der Steckverbinderachse bewegt werden. Dadurch ist es möglich die Position und des Federarms am Rastarm einzustellen und beliebig zu ändern. Je nachdem wie weit der Federarm am freien Ende des Rastarms anliegt, ist die Federkraft, die aus der Summe der Steifigkeit von Rastarm und Federarm resultiert unterschiedlich. Ist der Federarm weiter am freien Ende des Rastarms anliegend, ist die resultierende Federkraft höher, als wenn der Federarm weiter vom freien Ende am Rastarm anliegt. Actuating means are moved along the connector axis. This makes it possible to adjust the position and the spring arm on the locking arm and change as desired. Depending on how far the spring arm rests against the free end of the latching arm, the spring force, which is the sum of the stiffness of Lock arm and spring arm results differently. If the spring arm continues to rest against the free end of the latching arm, the resulting spring force is higher than when the spring arm rests further from the free end on the latching arm.
Zweckmäßig ist am freien Ende des Rastarms ein Rasthaken vorgesehen. Der Rasthaken ist dient zur Verrastung des Steckverbinders mit dem Receptacle. Durch Verrasten des Rasthakens hinter einer entsprechenden Ausnehmung oder Kante am Receptacle kann ein Abziehen des Steckverbinders vom Appropriately, a latching hook is provided at the free end of the latching arm. The latching hook is used to lock the connector to the receptacle. By locking the latching hook behind a corresponding recess or edge on the Receptacle can be removed from the connector

Dabei weist der Rasthaken eine Rastflanke und eine Einführschräge auf. Die Einführschräge weist in Steckrichtung, d.h. in Richtung des Steckgesichts und dem Receptacle zugewandt. Durch eine sehr flache Steigung kann eine In this case, the latching hook has a latching edge and an insertion bevel. The insertion bevel points in the direction of insertion, i. towards the mating face and the Receptacle. By a very flat slope can one
Schwenkbewegung des Rastarms auch bei hoher Kraft erzeugt werden. Die Steigung der Einführschräge ist vorzugsweise so ausgelegt, dass der Rastarm mit anliegendem Federarm ausgelenkt werden kann. So kann der Pivoting movement of the latching arm can be generated even at high power. The slope of the insertion bevel is preferably designed so that the locking arm can be deflected with adjacent spring arm. So can the
Steckverbinder mit oder auch ohne anliegenden Federarm auf ein Receptacle aufgerastet werden. Eine entsprechend flache Steigung das Auslenken des Rastarm, so dass der Rastarm auf dem Receptacle verrasten kann. Connectors with or without applied spring arm are snapped onto a receptacle. A correspondingly flat slope, the deflection of the locking arm, so that the locking arm can lock on the Receptacle.
Die Rastflanke ist rückseitig der Einführschräge in entgegengesetzte Richtung ausgerichtet. Dadurch kann die Rastflanke an einer entsprechenden Flanke oder einem Hinterschnitt am Receptacle verrasten. In der vorliegenden The catching edge is aligned on the reverse side of the insertion bevel in the opposite direction. As a result, the latching edge can latch on a corresponding flank or an undercut on the receptacle. In the present
Erfindung ist die Rastflanke jedoch nicht zwangsläufig senkrecht zur Invention, however, the locking edge is not necessarily perpendicular to
Steckrichtung des Steckverbinders ausgerichtet, wie aus dem Stand der Technik bekannt. Die Rastflanke und entsprechendes Gegenstück am Direction of insertion of the connector aligned, as known from the prior art. The locking edge and corresponding counterpart on
Receptacle sind so ausgebildet, dass beim Aufbringung einer entsprechenden Abziehkraft des Steckverbinders vom Receptacle eine geringe Kraft zum Auslenken des Rastarms erzeugt wird. Dabei ist die erzeugte Kraft jedoch deutlich geringer als die Kraft welche durch die Einführschräge beim Aufstecken auf ein Receptacle erzeugt wird. Die erzeugte Kraft durch die Rastflanke beim Abziehen vom Receptacle ist gerade so groß, dass der Rastarm ausgelenkt werden kann. Jedoch kleiner als die Kraft, welche benötigt wird um den Receptacle are designed so that when applying a corresponding peel force of the connector from the receptacle a small force for deflecting the locking arm is generated. However, the force generated is significantly lower than the force which is generated by the insertion bevel when plugging on a Receptacle. The force generated by the locking edge when pulling off the Receptacle is just so large that the locking arm deflected can be. However, less than the force needed around the
Rastarm mit anliegendem Federarm auszulenken. To deflect locking arm with adjacent spring arm.
Der Steckverbinder kann so zwei Zustände einnehmen: einen ersten, verriegelten Zustand und einen zweiten, entriegelten Zustand. Dabei ist das Betätigungsmittel im ersten, verriegelten Zustand in einer ersten, verriegelten Position und im zweiten, entriegelten Zustand in einer zweiten, entriegelten Position. Die erste, verriegelte Position ist dabei weiter in Steckrichtung, also weiter dem Steckgesicht des Steckverbinders zugewandt, als die zweite, entriegelte Position. Dies bezweckte, dass der Federarm in der ersten, verriegelten Position weiter am freien Ende des Rastarms anliegt, als in der zweiten, entriegelten Position. Der Kraft zum Auslenken des Federarms ist somit im ersten, verriegelten Zustand größer als im zweiten, entriegelten Zustand. The connector can thus assume two states: a first, locked state and a second, unlocked state. In this case, the actuating means in the first, locked state in a first, locked position and in the second, unlocked state in a second, unlocked position. The first, locked position is further in the insertion direction, so further facing the mating face of the connector, as the second, unlocked position. This meant that the spring arm remains in the first, locked position at the free end of the latching arm, as in the second, unlocked position. The force for deflecting the spring arm is thus greater in the first, locked state than in the second, unlocked state.
Durch diese Ausgestaltung kann der Steckverbinder in beiden Zuständen, dem verriegelten und entriegelten, auf ein Receptacle aufgesteckt und mit diesem verrastet werden. Jedoch kann der Steckverbinder nur im zweiten, entriegelten Zustand vom Receptacle abgezogen und dekontaktiert werden. With this configuration, the connector can be plugged into a receptacle in both states, the locked and unlocked, and locked with this. However, the connector can only be removed from the receptacle and dekontaktiert in the second, unlocked state.
Eine weitere zweckmäßige Ausführungsform sieht vor, dass der Steckverbinder eine Feder aufweist. Die Feder ist zwischen dem Grundkörper und dem A further expedient embodiment provides that the connector has a spring. The spring is between the main body and the
Betätigungsmittel angeordnet und übt auf beide eine Kraft aus. Dabei wird durch die Feder eine Zwangsbewegung des Betätigungsmittels in die erste, verriegelte Position bewirkt. Actuating arranged and exerts on both a force. In this case, a forced movement of the actuating means is effected in the first, locked position by the spring.
Durch die mit der Erfindung beschriebenen Merkmale wird ein neuartiger Steckverbinder vorgestellt, welcher einen Verriegelungsmechanismus aufweist, der aus nur wenigen beweglichen Teilen besteht. Die Ausfallsicherheit ist dabei sehr hoch und geringer Fehleranfällig. Durch die einfache Konstruktion ist eine Langlebigkeit des Steckverbinders, besonders bei häufigen Kontaktierungs- und Dekontaktierungsvorgängen gewährleistet. Ausführungsbeispiel The features described with the invention, a novel connector is presented, which has a locking mechanism consisting of only a few moving parts. The reliability is very high and low error prone. The simple design ensures longevity of the connector, especially with frequent contacting and Dekontaktierungsvorgängen. embodiment

In part, identical reference numerals are used for the same but possibly not identical elements. Different views of the same elements could be scaled differently.
Die Figur 1 zeigt eine perspektivische Darstellung eines erfindungsgemäßen Steckverbinders 1 in einem ersten, verriegelten Zustand. Der Steckverbinder 1 wird aus einem Grundkörper gebildet, welcher von einem Betätigungsmittel 4 umhüllt ist. Rückseitig ist am Steckverbinder 1 eine Kabelverschraubung 3 vorgesehen. Über die Kabelverschraubung 3 kann ein Kabel in den 1 shows a perspective view of a connector 1 according to the invention in a first, locked state. The connector 1 is formed from a base body, which is enveloped by an actuating means 4. On the back of the connector 1 a cable gland 3 is provided. About the cable gland 3, a cable in the
Steckverbinder 1 eingeführt und mit diesem verbunden werden. Steckseitig bildet der Steckverbinder 1 ein Steckgesicht, welches Zugriff auf ein im Connector 1 is inserted and connected to this. Plug side, the connector 1 forms a mating face, which access to a in
Steckverbinder 1 aufgenommenen Kontaktträger 2 ermöglicht. Connector 1 recorded contact carrier 2 allows.
Der Kontaktträger 2 im Steckgesicht des Steckverbinders 1 ist von vier Rastarmen 5 umgeben, welche eine Verriegelung mit einem The contact carrier 2 in the mating face of the connector 1 is surrounded by four locking arms 5, which is a lock with a
Gegensteckverbinder, einem Stecksockel oder sogenannten Receptacle ermöglichen. Die Rastarme 5 weisen im Steckgesicht des Steckverbinders 1 jeweils einen Rasthaken auf. Der Rasthaken ist nach innen, hin zur Mittelachse des Steckverbinders 1 ausgerichtet und bildet eine Einführschräge 7 sowie eine Rastflanke 6. Allow mating connector, a socket or so-called Receptacle. The latching arms 5 have in the mating face of the connector. 1 each have a latching hook. The latching hook is aligned inwardly toward the central axis of the connector 1 and forms an insertion bevel 7 and a latching edge. 6
Die Rastflanke 6 ist zur Rückseite, der Kabelverschraubung 3 des The latching edge 6 is to the back, the cable gland 3 of the
Steckverbinders 1 ausgerichtet. Die Einführschräge 7 ist rückseitig der Connector 1 aligned. The insertion 7 is the back of the
Rastflanke 6 in Richtung eines Gegensteckverbinders ausgerichtet. Über die Einführschräge 7 kann der Rastarm 5 beim Verbinden mit einem Locking edge 6 aligned in the direction of a mating connector. About the insertion 7, the locking arm 5 when connecting to a
Gegensteckverbinder ausgelenkt werden um mit diesem zu verrasten. Mating connectors are deflected to lock with this.
Außenliegend ist an jedem Rastarm 5 ein Federarm 9 angeordnet. Der On the outside, a spring arm 9 is arranged on each latching arm 5. Of the
Federarm 9 liegt dabei am Rastarm 5 an und berührt diesen über dessen gesamte Länge. Spring arm 9 rests against the latching arm 5 and touches it over its entire length.
Die Figur 2 zeigt eine perspektivische Darstellung des erfindungsgemäßen Steckverbinders 1 in einem zweiten, entriegelten Zustand. Im zweiten, entriegelten Zustand ist das Betätigungsmittel 4 in einer zweiten, entriegelten Position. Das Betätigungsmittel 4 ist dafür weiter in Richtung der 2 shows a perspective view of the connector 1 according to the invention in a second, unlocked state. In the second, unlocked state, the actuating means 4 in a second, unlocked position. The actuating means 4 is for this purpose in the direction of
Kabelverschraubung 3 positioniert als in der ersten, verriegelten Position. Cable gland 3 positioned as in the first locked position.
Durch die zweite Position, welche weiter entfernt von der Steckseite und dem Steckgesicht des Steckverbinders 1 ist, sind die Federarme 9 ebenfalls aus dem Steckgesicht bewegt. By the second position, which is further away from the mating side and the mating face of the connector 1, the spring arms 9 are also moved from the mating face.
Dadurch liegen die Federarme 9 nicht mehr soweit an den freien Enden der Rastarme an, wie in der ersten, verriegelten Position. Dadurch ist die Federkraft der Rastarme 5 bei einer Schwenkbewegung, radial nach außen, kleiner als im ersten, verriegelten Zustand des Steckverbinders.  As a result, the spring arms 9 are no longer so far at the free ends of the latching arms, as in the first, locked position. As a result, the spring force of the latching arms 5 during a pivoting movement, radially outward, smaller than in the first, locked state of the connector.
Die zwei Zustände des Steckverbinder 1 , der erste, verriegelte Zustand und der zweite, entriegelte Zustand, sind noch einmal in den Figuren 3 und 4 The two states of the connector 1, the first locked state and the second unlocked state, are again in FIGS. 3 and 4
dargestellt. Dabei zeigen die Figuren 3 und 4 jeweils eine Schnittdarstellung des Steckverbinder 1 in der jeweiligen Position. In der Figur 3 sind die Rastarme 5 erkennbar, welche Steckseitig über shown. The figures 3 and 4 each show a sectional view of the connector 1 in the respective position. In the figure 3, the latching arms 5 can be seen, which plug side over
Rasthaken verfügen. Die Rasthaken bilden je eine Einführschräge 7 sowie eine Rastflanke 6 aus. An der Rastflanke 6 ist ein Receptacle eines Latch hooks feature. The latching hooks each form an insertion bevel 7 and a latching edge 6. At the locking edge 6 is a receptacle of a
Gegensteckverbinders verrastet. Der Übersicht halber, ist das Receptacle nur schematisch dargestellt. Mating connector locked. For the sake of clarity, the receptacle is shown only schematically.
An den Rastarmen 5 liegt jeweils ein Federarm 9 an. Durch den anliegenden Federarm 9 ist die Federkraft der Rastarme 5 erhöht. Eine äußere, die Rast- und Federarme 5, 9 umgebende Hülse 10 des Grundkörpers ist so ausgebildet, dass Rast- und Federarme 5, 9 zusammen noch eine Schwenkbewegung ausüben können. In dieser speziellen Ausführungsform sind die Hülse 10 und der Rastarm 5 einteilig ausgebildet. At the latching arms 5 is in each case a spring arm 9 at. By the adjacent spring arm 9, the spring force of the latching arms 5 is increased. An outer, the latching and spring arms 5, 9 surrounding sleeve 10 of the body is designed so that locking and spring arms 5, 9 together can still perform a pivoting movement. In this particular embodiment, the sleeve 10 and the latching arm 5 are integrally formed.
Die Federarme 9 sind mit dem Betätigungsmittel 4 einteilig ausgebildet. Das Betätigungsmittel 4 wird durch eine Feder 8, welche zwischen dem The spring arms 9 are formed integrally with the actuating means 4. The actuating means 4 is by a spring 8, which between the
Betätigungsmittel 4 und dem Grundkörper angeordnet ist, in die erste, verriegelte Position bezwungen. Durch diese Zwangsverriegelung wird sichergestellt, dass der Steckverbinder 1 notfalls immer verriegelt und nicht entriegelt ist. Actuating means 4 and the base body is arranged, conquered in the first, locked position. This positive locking ensures that the connector 1 is always locked and unlocked if necessary.
Die Figur 4 zeigt den Steckverbinder 1 im zweiten, entriegelten Zustand. Das Betätigungsmittel 4 ist in eine hintere, zweite, entriegelte Position bewegt. 4 shows the connector 1 in the second, unlocked state. The actuating means 4 is moved to a rear, second, unlocked position.
Dadurch sind die Federarme 9 aus dem Bereich der freien Enden der Rastarme 5 entfernt. Die Federkraft der Rastarme 5 ist so deutlich geringer als in der ersten, verriegelten Position wie in Figur 3 dargestellt. As a result, the spring arms 9 are removed from the region of the free ends of the latching arms 5. The spring force of the latching arms 5 is so much lower than in the first, locked position as shown in Figure 3.
In diesem Zustand können die Rastarme 5 einfach eine Schwenkbewegung ausführen und so die Verrastung mit dem Receptacle lösen. Durch eine leichte Anschrägung der Rastflanken 6 oder dem entsprechenden Bereich am In this state, the locking arms 5 can easily perform a pivoting movement and so solve the catch with the Receptacle. By a slight bevel of the locking edges 6 or the corresponding area on
Receptacle reich die so durch Abziehen des Steckverbinders 1 erzeugte radiale Kraft für eine Schwenkbewegung der Rastarme 5. Die im Zustand der Figur 3 erzeugte Kraft durch Rast- und Federarme 5, 9 sind zu groß um durch eine Kraft überwunden zu werden. Receptacle rich so generated by pulling off the connector 1 radial force for a pivoting movement of the locking arms 5. The force generated in the state of Figure 3 by latching and spring arms 5, 9 are too large by a Force to be overcome.
Der Vorteil der Erfindung besteht darin, dass die Federkraft der Rastarme 5 durch die Federarme 9 erhöht oder reduziert werden kann. Durch eine entsprechend vorteilhafte Auslegung der Rastflanken 6 und zugehörigen Gegenflanken am Receptacle kann so eine sichere Verrastung wie auch eine gewollte Entriegelung des Steckverbinders eingestellt werden. The advantage of the invention is that the spring force of the latching arms 5 can be increased or reduced by the spring arms 9. By a correspondingly advantageous design of the locking edges 6 and associated counter flanks on Receptacle so a secure locking as well as a desired unlocking of the connector can be adjusted.
