Description

Die Erfindung betrifft einen elektrischen Steckverbinder zum Anschluss eines Gegensteckverbinders, mit einem rohrförmigen Gehäuseabschnitt, in dem ein elektrischer Steckkontakte tragender Isolierkörper angeordnet ist, wobei der Gehäuseabschnitt eine Steckseite für den Gegensteckverbinder sowie eine Anschlussseite für die Steckkontakte aufweist und der Isolierkörper mit dem Gehäuseabschnitt verrastet und Werkzeug lösbar entrastbar ist, und wobei zwischen dem Gehäuseabschnitt und dem Isolierkörper mindestens eine Rasteinrichtung angeordnet ist, die zumindest axial unverrückbar in dem Gehäuseabschnitt gehalten ist und wenigstens teilweise in eine Aufnahmeausnehmung des Gehäuseabschnittes eingreift, und die mindestens ein radial federnd auslenkbares Abstützelement für den Isolierkörper aufweist, das den Isolierkörper mit dem Gehäuseabschnitt verrastet und in axialer Richtung fixiert. Die Erfindung betrifft außerdem ein Entriegelungswerkzeug für den Isolierkörper eines solchen elektrischen Steckverbinders.The invention relates to an electrical connector for connecting a mating connector, comprising a tubular housing portion in which an electrical plug contacts supporting insulating body is arranged, wherein the housing portion has a mating side for the mating connector and a connection side for the plug contacts and the insulating body with the housing portion locked and tool is releasably unlocked, and wherein between the housing portion and the insulating body at least one latching device is arranged, which is at least axially held immovably in the housing portion and at least partially engages in a receiving recess of the housing portion, and having at least one radially resilient deflectable support member for the insulating body, which locks the insulating body with the housing portion and fixed in the axial direction. The invention also relates to an unlocking tool for the insulating body of such an electrical connector.

Steckverbinder der eingangs genannten Art sind in vielfältigen Ausführungsformen aus dem Stand der Technik bekannt. Dabei ist die Rasteinrichtung derart ausgelegt, dass sie den Isolierkörper mit den darin aufgenommenen Steckkontakten sicher miteinander verbindet und insbesondere ein unbeabsichtigtes Lösen des Isolierkörpers von dem Steckverbindergehäuse verhindert. Dies ist notwendig, um einerseits eine Beschädigung der Kontaktierung der Litzenleiter zu den elektrischen Kontakten durch mechanische Einflüsse zu verhindern und um andererseits mit dem Steckverbinder in Berührung kommende Personen vor gefährlichen Spannungen zu schützen.Connectors of the type mentioned are known in various embodiments of the prior art. In this case, the latching device is designed such that it the insulating body with the plug contacts received therein securely connects together and in particular prevents unintentional release of the insulator of the connector housing. This is necessary on the one hand to prevent damage to the contacting of the stranded conductors to the electrical contacts by mechanical influences and on the other hand to protect persons coming into contact with the connector from dangerous voltages.

Isolierkörper werden bei bekannten Steckverbindern meist von einem hinteren den Anschlussleitungen zugeordneten Ende in den aufnehmenden Gehäuseabschnitt eingeführt, bis der Isolierkörper an einem Anschlag des Steckverbindergehäuses anliegt und anschließend beispielsweise mit einem Sprengring oder dergleichen in dem Gehäuseabschnitt festgelegt, der in eine dort vorgesehene Ringnut eingreift und den Isolierkörper stützt. Alternativ ist bekannt, zuerst einen Schnappring in den zur Aufnahme des Isolierkörpers vorgesehenen Gehäuseabschnitt einzubringen, dort einzurasten und anschließend den Isolierkörper in den Gehäuseabschnitt einzuführen, wobei der Schnappring den Isolierkörper selbstständig verriegelt. Die Verriegelung kann dabei unlösbar oder Werkzeug lösbar ausgebildet sein, abhängig davon, ob der Schnappring zugängig angeordnet ist oder nicht.Insulating body are usually introduced in known connectors of a rear end of the connecting lines in the female housing portion until the insulator abuts against a stop of the connector housing and then set, for example, with a snap ring or the like in the housing portion which engages in a provided there annular groove and the Insulating body supports. Alternatively, it is known to first introduce a snap ring in the space provided for receiving the insulating housing portion, there latch and then introduce the insulating body in the housing portion, wherein the snap ring locks the insulating body independently. The lock can be permanent or tool detachable, depending on whether the snap ring is arranged accessible or not.

Dabei hat es sich insbesondere bei Flanschsteckverbindern für die Erstmontage oder für Wartungs-/Reparaturfälle als nachteilig erwiesen, wenn der Isolierkörper von der Anschlussseite der elektrischen Steckkontakte aus Werkzeug lösbar ist, da in einem solchen Fall das Steckverbindergehäuse von dem Maschinengehäuse gelöst werden muss, um die Entrastung des Isolierkörpers vorzunehmen. Dieser zusätzliche Aufwand ist in der Regel unerwünscht. Zur Vermeidung dieses Nachteils sind Werkzeug lösbare Steckverbinder aus dem Stand der Technik bekannt, bei denen ein Schnappring in dem aufnehmenden Gehäuseabschnitt von der Steckseite oder Anschlussseite des Steckverbindergehäuses aus erreichbar ist. Damit kann der verrastete Isolierkörper mittels eines geeignet ausgebildeten Entriegelungswerkzeuges problemlos von dem Gehäuseabschnitt gelöst und in axialer Richtung verschoben werden. Beispielhaft wird auf das Gebrauchsmuster DE 91 04 985 U1 verwiesen.It has proved particularly disadvantageous in flange connectors for the initial installation or for maintenance / repair cases when the insulating body of the connection side of the electrical plug contacts tool is solvable, since in such a case, the connector housing must be solved by the machine housing to the Unscrew the insulator make. This extra effort is usually undesirable. To avoid this disadvantage, tool-releasable connectors are known from the prior art, in which a snap ring in the female housing section from the mating side or terminal side of the connector housing can be reached. Thus, the latched insulating body by means of a suitably designed unlocking tool easily from the housing section be released and moved in the axial direction. An example is the utility model DE 91 04 985 U1 directed.

Diese schlägt vor, den in einem Stecker- bzw. Kupplungsgehäuse angeordneten Isolierkörper mittels eines abschnittsweise in seiner in Einschubrichtung außenliegenden Stirnfläche angreifenden und in einer Radialnut des jeweiligen Gehäuses abgestützten Schnappringes zu halten, wobei sich die andere innenliegende Stirnfläche des Isolierkörpers an einem Ringbund abstützt. Der Schnappring weist wenigstens vier gleichmäßig über seinen Umfang verteilt angeordnete, an einer in Einschubrichtung ausliegenden Stirnfläche des Isolierkörpers anliegende Stützschultern auf. Er ist insbesondere insgesamt als in Umfangsrichtung stufenförmig zylindrischer Ringkörper ausgebildet. Die Schrift lässt offen, ob der Isolierkörper dabei von der Steckseite oder der Anschlussseite des Steckverbinders entrastbar und welche in Richtung bezüglich des aufnehmenden Gehäuseabschnitts der Isolierkörper danach verschiebbar ist.This proposes to hold the arranged in a plug or coupling housing insulator by means of a sectionally acting in its insertion direction outside end face and supported in a radial groove of the respective housing snap ring, wherein the other inner end face of the insulating body is supported on a collar. The snap ring has at least four evenly distributed over its circumference arranged on a lying in the direction of insertion end face of the insulator adjacent support shoulders. In particular, it is designed as a whole in the form of a ring-shaped annular body in the circumferential direction. The document leaves open whether the insulating body can be unlocked from the mating side or the connection side of the connector and which is then displaceable in the direction with respect to the female housing section of the insulating body.

Ein Nachteil dieses Standes der Technik ist darin begründet, dass das Steckverbindergehäuse eine innenliegende umlaufende Ringnut für den Schnappring benötigt, die insbesondere bei Flanschsteckverbindern, die als im wesentlichen zylinderförmig gestaltetes Druckgussteil ausgeführt sind, durch Nacharbeit hergestellt werden muss. Außerdem ist die darin vorgeschlagene Lösung insbesondere bei Steckverbindern mit geringem Innendurchmesser und mehreren elektrischen Steckkontakten kaum anwendbar.A disadvantage of this prior art is due to the fact that the connector housing requires an internal circumferential annular groove for the snap ring, which must be made by rework, especially in Flanschsteckverbindern, which are designed as a substantially cylindrical shaped diecasting.

Diese Aufgabe wird erfindungsgemäß durch einen elektrischen Steckverbinder und ein Entriegelungswerkzeug mit den Merkmalen der nebengeordneten Patentansprüche 1, 11 gelöst. Weitere vorteilhafte Ausgestaltungen sind den jeweiligen rückbezogenen Patentansprüchen zu entnehmen.This object is achieved by an electrical connector and an unlocking tool with the features of the independent claims 1, 11 solved.

Bei dem erfindungsgemäßen elektrischen Steckverbinder ist der Isolierkörper von der Steckseite des rohrförmigen Gehäuseabschnitts aus Werkzeug lösbar. Der Steckverbinder weist erfindungsgemäß eine Rasteinrichtung für den Isolierkörper und eine in dem Gehäuseabschnitt angeordnete Aufnahmeausnehmung für die Rasteinrichtung auf, die in Umfangsrichtung des Gehäuseabschnittes in dem der Isolierkörper angeordnet ist, geteilt ausgeführt sind. Dabei weist die Rasteinrichtung mindestens zwei voneinander getrennte schalenförmige Rastteile und die Aufnahmeausnehmung eine entsprechende Anzahl von voneinander getrennten Rastteileaufnahmen für die Rastteile auf, die an der Innenwand des Gehäuseabschnitts in Umfangsrichtung beabstandet voneinander angeordnet sind, wobei die Rastteile außen in der Form an die Rastteileaufnahmen angepasst sind und jeweils mindestens ein seitlich abstehendes Abstützelement für den Isolierkörper aufweisen.In the electrical connector according to the invention, the insulating body of the plug side of the tubular housing portion of the tool is releasable. The connector according to the invention comprises a latching device for the insulating body and arranged in the housing portion receiving recess for the latching device, which is arranged in the circumferential direction of the housing portion in which the insulating body, divided executed. In this case, the latching device has at least two separate cup-shaped latching parts and the receiving recess a corresponding number of separate Rastteileaufnahmen for the locking parts, which are arranged spaced from each other on the inner wall of the housing portion in the circumferential direction, wherein the latching parts are adapted externally in the form of the Rastteileaufnahmen and in each case have at least one laterally projecting support element for the insulating body.

Die Rastteile und die Rastteileaufnahmen sind in Umfangsrichtung so dimensioniert, dass sich direkt ohne Abstand aneinander gereiht in Umfangsrichtung nur entlang einem Teil der Innenwand des Gehäuseabschnittes des Steckverbinders erstrecken würden. Sie benötigen somit in der Umfangsrichtung des Gehäuseabschnittes deutlich weniger Raum als eine ringförmig geschlossen ausgebildete Rasteinrichtung und eine entsprechend ausgeführte Aufnahmeausnehmung für eine solche Rasteinrichtung. Die Erfindung ermöglicht auch bei Steckverbindern, die ein Steckverbindergehäuse mit einem relativ geringen Innendurchmesser und einer verhältnismäßig dünnen Wandstärke aufweisen, ein sicheres lösbares Verrasten des Isolierkörpers mit dem Gehäuseabschnitt von der Steckseite aus, und zwar ohne Stabilität des Steckverbindergehäuses wesentlich zu mindern. Das mindestens eine an den Rastteilen vorgesehene Abstützelement kann beim Verriegeln des Isolierkörpers in dem Gehäuseabschnitt in eine Ringnut des Isolierkörpers einrasten und/oder einen Hinterschnitt des Isolierkörpers hinterrasten. Es kann auf der dem Isolierkörper zugeordneten Umfangsseite mit oder ohne seitlichen Rasthaken ausgebildet sein.The latching parts and the Rastteileaufnahmen are circumferentially dimensioned so that directly without spacing strung together in the circumferential direction would extend only along a portion of the inner wall of the housing portion of the connector. Thus, in the circumferential direction of the housing section, they require significantly less space than a latching device of annular design and a correspondingly designed receiving recess for such a latching device. The invention also allows for connectors having a connector housing with a relatively small inner diameter and a relatively thin wall thickness, a reliable releasable latching of the insulating body with the housing portion of the plug side, without substantially reducing stability of the connector housing. The at least one provided on the locking parts support element can engage in locking the insulating body in the housing portion in an annular groove of the insulating and / or an undercut behind the insulator. It may be formed on the insulating body associated peripheral side with or without lateral latching hooks.

Zur axialen, radialen und/oder tangentialen Fixierung der Rastteile an der Innenwand des Gehäuseabschnittes weisen die Rastteilaufnahmen vorzugsweise Hinterschnitte und die Rastteile vorzugsweise den Hinterschnitten zugeordnete Rastmittel auf. Die Hinterschnitte können sich dabei in Umfangsrichtung, in axialer und/oder in radialer Richtung der Innenwand erstrecken. Die jeweiligen mit den Hinterschnitten zusammenwirkenden Rastmittel verlaufen an den Rastteilen vorzugsweise in entsprechender Richtung. Die Rastmittel verbinden das jeweilige Rastteil lagestabil ohne oder mit geringem Spiel mit dem Gehäuseabschnitt des Steckverbinders.For axial, radial and / or tangential fixation of the latching parts on the inner wall of the housing section, the latching part receptacles preferably have undercuts and the latching parts preferably have latching means assigned to the undercuts. The undercuts may extend in the circumferential direction, in the axial and / or in the radial direction of the inner wall. The respective latching means cooperating with the undercuts preferably extend in the corresponding direction on the latching parts. The locking means connect the respective locking part in a stable position without or with little play with the housing portion of the connector.

Bei einer besonders begünstigten Ausführungsform der Erfindung sind die Hinterschnitte an der Innenwand des Gehäuseabschnittes in Umfangsrichtung der Rastaufnahmen seitlich angeordnet. Sie erstrecken sich dabei im wesentlichen in axialer Richtung der Innenwand des Gehäuseabschnittes. Die Verbindung mit den Rastteilen erfolgt dementsprechend nur an oder entlang den axialen Seitenrändern der Rastteile. Indem die Rastteile schalenförmig ausgebildet sind, sind diese orthogonal zu ihren Seitenrändern einfach rückfedernd deformierbar, sodass die Rastmittel leicht in die Hinterschnitte eingeführt bzw. eingerastet werden können. Um das Einführen zusätzlich zu vereinfachen, können die in Umfangsrichtung seitlichen sich axial erstreckenden Seitenränder der Rastteile selbst noch in radialer Richtung federnd ausgebildet sein.In a particularly favorable embodiment of the invention, the undercuts on the inner wall of the housing portion in the circumferential direction of the locking receptacles are arranged laterally. They extend substantially in the axial direction of the inner wall of the housing portion. The connection with the locking parts is accordingly only at or along the axial side edges of the locking parts. By the locking parts are formed cup-shaped, these are orthogonal to their side edges simply resiliently deformable, so that the locking means can be easily inserted or snapped into the undercuts. In order to simplify the insertion in addition, the circumferentially laterally extending axially lateral edges of the locking parts may be resilient even in the radial direction.

Bei einer bevorzugten Ausführungsform des erfindungsgemäßen elektrischen Steckverbinders liegen die Rastteile derart vertieft in den Rastteileaufnahmen ein, dass nur die Abstützelemente der Rastteile über die Innenwand des Gehäuseabschnittes vorstehen. Damit kann sich der Isolierkörper radial beidseitig neben jeder der Rastteileaufnahmen und den Rasteteilen an der Innenwand des Gehäuseabschnittes direkt abstützen, ohne Kräfte auf die Rastteile, insbesondere auf deren Abstützelemente zu übertragen. Damit ist ein unbeabsichtigtes Lösen der Verrastung zwischen dem Isolierkörper und dem aufnehmenden Gehäuseabschnitt sicher ausgeschlossen.In a preferred embodiment of the electrical connector according to the invention, the latching parts are so deepened in the latching part receptacles that only the support elements of the latching parts project beyond the inner wall of the housing section. Thus, the insulating body can be supported radially on both sides next to each of the Rastteileaufnahmen and the locking parts on the inner wall of the housing portion directly without transmitting forces on the locking parts, in particular on the support elements. This is an unintentional release the locking between the insulating body and the female housing portion safely excluded.

Bei einer Ausführungsform der Erfindung erstrecken sich die mindestens zwei Rastteileaufnahmen ausgehend von der Steckseite des Gehäuseabschnittes in axialer Richtung des Gehäuseabschnittes und enden vor dessen Anschlussseite. Sie sind vorzugsweise zur Steckseite des Gehäuseabschnittes hin offen ausgebildet. Damit können die Rastteile schnell und besonders einfach von vorne in den Gehäuseabschnitt und in die Rastteileaufnahmen der Innenwand eingeführt und dort festgelegt beispielsweise verrastet werden. Um das Einbringen in die Rastteileaufnahmen weiter zu erleichtern und um eine besonders kostengünstige Herstellung des Gehäuses des Steckverbinders zu ermöglichen, sind die Rastteileaufnahmen zur Steckseite des Gehäuseabschnittes hin vorzugsweise offen ausgebildet. Dadurch können die Rastteile insbesondere mit ihren axialen Seitenrändern hinter die axialen seitlichen Hinterschnitte der Rastteileaufnahmen mit minimalem Kraftaufwand direkt eingeschoben werden, bis sie an dem der Anschlussseite des Gehäuseabschnittes zugeordneten Ende der Rastteilaufnahmen anstehen und die Rastmittel einrasten.In one embodiment of the invention, the at least two latching part receptacles extend starting from the plug side of the housing section in the axial direction of the housing section and terminate before its connection side. They are preferably designed to be open towards the mating side of the housing section. Thus, the locking parts can be quickly and very easily introduced from the front into the housing section and in the locking part receptacles of the inner wall and fixed there, for example, be locked. In order to facilitate the introduction into the catch part receptacles and to enable a particularly cost-effective production of the housing of the connector, the catch member receptacles are preferably open to the plug side of the housing portion. Thereby, the locking parts can be inserted directly with minimal effort, in particular with their axial side edges behind the axial side undercuts of Rastteileaufnahmen until they are pending at the connection side of the housing portion associated end of the locking part receptacles and engage the locking means.

Dabei hat es sich als besonders günstig erwiesen, die Rastteileaufnahmen mit in Umfangsrichtung seitlich angeformten Einschubschienen für die Rastteile auszubilden. Die angeformten Einschubschienen erstrecken sich von der Steckseite des Gehäuseabschnittes bis nahezu zu der Anschlussseite. Sie weisen dabei vorzugsweise eine Länge auf, die den axialen Seitenrändern der Rastteile entspricht.It has proven to be particularly advantageous to form the locking part recordings with laterally integrally formed insertion rails for the locking parts. The molded-in slide rails extend from the plug side of the housing section almost to the connection side. They preferably have a length corresponding to the axial side edges of the locking parts.

Bei einer begünstigten Ausführungsform der Erfindung sind die Rastteile in Richtung der Steckseite des Gehäuseabschnittes zumindest bereichsweise dünnwandiger ausgeführt als in Richtung der Anschlussseite des Gehäuseabschnittes. Der dünnwandigere Bereich grenzt dabei zumindest an die Abstützelemente an und erstreckt sich axial in Richtung der Steckseite des Gehäuseabschnittes. Vorteilhafterweise reicht der dünnwandigere Bereich dabei bis an die Steckseite des Gehäuseabschnittes heran. Bevorzugt wird eine Ausführungsform, bei der die Rastteile mindestens einen dünnwandigen Umfangsabschnitt aufweisen, der in Richtung der Steckseite des Gehäuseabschnittes offen ausgebildet ist und sich als Axialausnehmung wenigstens bis zu dem Abstützelement erstreckt. Auf diese Weise wird ein Freiraum zwischen dem jeweiligen Rastteil und dem Isolierkörper geschaffen, der einen Zugang zu dem mindestens einen Abstützelement des jeweiligen Rastteils mit einem geeignet ausgebildeten Entriegelungswerkzeug für den Isolierkörper gebildet.In a favored embodiment of the invention, the latching parts in the direction of the plug side of the housing portion are at least partially thin-walled designed as in the direction of the connection side of the housing portion. The thinner-walled region adjoins at least the supporting elements and extends axially in the direction of the plug-in side of the housing section. Advantageously, the thinner-walled region extends as far as the plug-in side of the housing section. Preferred is an embodiment in which the latching parts have at least one thin-walled peripheral portion, which is designed to be open in the direction of the plug-in side of the housing section and extends as an axial recess at least as far as the support element. In this way, a free space is created between the respective latching part and the insulating body, which forms an access to the at least one support element of the respective latching part with a suitably designed unlocking tool for the insulating body.

Bei allen möglichen Ausführungsformen der Erfindung können die mindestens zwei Rastteile in der Form identisch oder unterschiedlich ausgebildet sein, einen einheitlichen und/oder uneinheitlichen Seitenabstand zueinander aufweisen, wobei der Gehäuseabschnitt eine der Anzahl der Rastteile entsprechende oder auch eine größere Anzahl von Rastteileaufnahmen aufweisen kann. Vorzugsweise werden identisch ausgebildete Rastteile verwendet und in einem einheitlichen Seitenabstand zueinander angeordnet, wobei nicht mehr Rastteileaufnahmen als Rastteile vorgesehen sind.In all possible embodiments of the invention, the at least two latching parts in the form may be identical or different, have a uniform and / or non-uniform side distance to each other, wherein the housing portion may have a number of locking parts corresponding or a larger number of Rastteileaufnahmen. Preferably identically formed locking parts are used and arranged in a uniform side distance from each other, with no more Rastteileaufnahmen are provided as locking parts.

Das erfindungsgemäße Entriegelungswerkzeug für den Isolierkörper eines vorstehend beschriebenen erfindungsgemäßen elektrischen Steckverbinders weist mindestens eine an einem Handgriff angeordnete, starr mit dem Handgriff verbundene Entriegelungshülse, die in die Steckseite des Gehäuseabschnittes des Steckverbinders mit einem vorderen Führungsbereich teilweise einführbar ist und sich dabei an der Innenwand des Gehäuseabschnittes seitlich abstützt, und eine in der Entriegelungshülse längs verschiebbar geführte, in die Steckseite des Gehäuseabschnittes mit einem vorderen Einführbereich einführbare und auf den Isolierkörper stirnseitig aufsetzbare Verschiebehülse auf, wobei sich die Verschiebehülse mit ihrer Außenwand an der Innenwand der Entriegelungshülse seitlich abstützt. Dabei weist die Entriegelungshülse mindestens zwei an dem Führungsbereich vorne angeordnete angeformte Entriegelungsklingen zum radialen Entrasten der Abstützelemente der mindestens zwei Rastteile von dem Isolierkörper auf. Die Verschiebehülse weist außen einen nahe dem vorderen Führungsbereich der Entriegelungshülse angeordneten radial nach außen vorstehenden umlaufenden Abstützbund auf, der eine seitliche Abstützung der Verschiebehülse an der Innenwand des Gehäuseabschnittes ermöglicht, wobei an dem Abstützbund sich axial erstreckende Durchtritte für die Entriegelungsklingen der Entwicklungshülsen vorgesehen sind.The unlocking tool according to the invention for the insulating body of an electrical connector according to the invention described above has at least one arranged on a handle, rigidly connected to the handle unlocking sleeve which is partially inserted into the mating side of the housing portion of the connector with a front guide portion and thereby on the inner wall of the housing portion supported laterally, and a longitudinally displaceably guided in the unlocking sleeve, in the mating side of the housing portion with a front lead-in insertable and on the insulator frontally attachable sliding sleeve, wherein the sliding sleeve is supported laterally with its outer wall on the inner wall of the Entriegelungshülse. In this case, the unlocking sleeve has at least two integrally formed on the front guide Entriegelungsklingen for radial unlatching of the supporting elements of the at least two locking parts of the insulating body. The sliding sleeve has outside a close to the front guide portion of the Entriegelungshülse arranged radially outward projecting circumferential Abstützbund which allows lateral support of the sliding sleeve on the inner wall of the housing portion, wherein on the Abstützbund axially extending passages are provided for the Entriegelungsklingen the development sleeves.

Die Verschiebehülse und die Entriegelungshülse sind in der Form aneinander und an die Innenwand des Gehäuseabschnittes, in dem der Isolierkörper angeordnet ist, angepasst. Die Anzahl und die Anordnung der Entriegelungsklingen entspricht dabei der der Abstützelemente der vorgesehenen Rastteile. Zum Entriegeln des Isolierkörpers wird zuerst die Verschiebehülse in den Gehäuseabschnitt mit ihrem Einführbereich eingeschoben, bis sie auf dem Isolierkörper aufsitzt. Dabei stützt sich die Verschiebehülse vorne über ihren Abstützbund an der Innenwand des rohrförmigen Gehäuseabschnittes ab. Anschließend wird die Entriegelungshülse gegenüber der Verschiebehülse in Richtung des Isolierkörpers verschoben, bis der Führungsbereich der Entriegelungshülse sich mit dem Einführbereich der Verschiebehülse deckt. Dabei erreichen die Entriegelungsklingen der Entriegelungshülse die Abstützelemente der Rastteile und verrücken diese am freien Ende seitlich radial in Richtung der Innenwand des Gehäuseabschnittes soweit, dass der Isolierkörper freigegeben ist. Jetzt genügt eine geringe axiale Kraft auf den Isolierkörper in Steckrichtung, der mittels der Verschiebehülse einwirkt, um diesen in dem Gehäuseabschnitt in Richtung der Anschlussseite zu verschieben bzw. diesen vollständig aus dem Gehäuseabschnitt herauszuschieben.The sliding sleeve and the unlocking sleeve are in the form of each other and to the inner wall of the housing portion in which the insulating body is arranged adapted. The number and arrangement of Entriegelungsklingen corresponds to that of the supporting elements of the provided locking parts. To unlock the insulating the sliding sleeve is first inserted into the housing section with its insertion area until it rests on the insulating body. In this case, the sliding sleeve is supported at the front over its support collar on the inner wall of the tubular housing portion. Subsequently, the unlocking sleeve is displaced relative to the sliding sleeve in the direction of the insulating body until the guide region of the unlocking sleeve coincides with the insertion region of the sliding sleeve. In this case, the unlocking blades of the unlocking sleeve reach the supporting elements of the locking parts and displace them at the free end laterally radially in the direction of the inner wall of the housing section so far that the insulating body is released. Now a small axial force on the insulating body in the insertion direction, which acts by means of the sliding sleeve to move it in the housing portion in the direction of the connection side or push it completely out of the housing section is sufficient.

Vorzugsweise weist der Handgriff eine Druckfeder auf, die die Verschiebehülse in Richtung des Einführbereiches der Entriegelungshülse Federkraft beaufschlagt. Sobald bei dieser Ausführungsform die Entriegelungsklingen der Entriegelungshülse den Isolierkörper von den Abstützelementen entriegelt haben, verschiebt die Federkraft die auf den Isolierkörper aufsitzende Verschiebehülse gegenüber der Entriegelungshülse und dem Handgriff und damit den Isolierkörper selbstständig in Richtung der Anschlussseite des Gehäuseabschnittes.Preferably, the handle on a compression spring which acts on the sliding sleeve in the direction of the insertion of the unlocking sleeve spring force. As soon as the unlocking blades of the unlocking sleeve have unlocked the insulating body from the supporting elements in this embodiment, the spring force displaces the sliding sleeve seated on the insulating body relative to the unlocking sleeve and the handle and thus the insulating body independently in the direction of the connection side of the housing section.

Der Vorteil der Erfindung liegt insbesondere darin, dass aufgrund der konstruktiven Ausbildung der Befestigung des Isolierkörpers in dem Gehäuseabschnitt vorhandene Isolierkörper bei einer neuen Steckergeneration verwendet werden können. Die Einbringung der Isolierkörper kann dabei sogar im angeschlossenen Zustand in dem neuen Stecker vorgenommen werden.The advantage of the invention is in particular that due to the structural design of the attachment of the insulating in the Housing section existing insulator can be used in a new plug generation. The introduction of the insulating body can be made even in the connected state in the new plug.

Die Figur 1 zeigt einen erfindungsgemäßen elektrischen Steckverbinder 1 mit einem in einem Gehäuse 2 aufgenommenen Isolierkörper 3. Der Isolierkörper 3 ist mittels Rastteilen 4 in einem rohrförmigen Gehäuseabschnitt 5 des Gehäuses 2 verrastet. Der Isolierkörper 3 trägt elektrische Steckkontakte 6, die sich von einer Steckseite 7 axial bis zu einer Anschlussseite 8 des Gehäuseabschnittes 5 erstrecken. Der Isolierkörper 3 ist von der Steckseite 7 des Gehäuseabschnittes 5 mittels des in der Figur 5 dargestellten Entriegelungswerkzeuges 9 entrastbar und dann in Richtung der Anschlussseite 8 des Gehäuseabschnittes 5 axial verschiebbar. Die Rastteile 4, die eine Rasteinrichtung 10 für den Isolierkörper 3 bilden, sind zwischen dem Gehäuseabschnitt 5 und dem Isolierkörper 3 angeordnet und axial sowie radial unverrückbar in dem Gehäuseabschnitt gehalten. Sie liegen oder greifen jeweils zumindest teilweise in Rastteilaufnahmen 11 ein, die zusammengenommen eine Aufnahmeausnehmung 12 für die Rasteinrichtung 10 darstellen.The FIG. 1 shows an electrical connector 1 according to the invention with a recorded in a housing 2 insulator 3. The insulating body 3 is latched by means of locking parts 4 in a tubular housing portion 5 of the housing 2. The insulating body 3 carries electrical plug contacts 6, which differ from a plug side 7 extend axially to a connection side 8 of the housing portion 5. The insulating body 3 is of the mating side 7 of the housing portion 5 by means of in the FIG. 5 unlocking tool 9 shown unlocked and then axially displaceable in the direction of the connection side 8 of the housing portion 5. The locking parts 4, which form a latching device 10 for the insulating body 3, are arranged between the housing portion 5 and the insulating body 3 and held axially and radially immovable in the housing portion. They are or at least partially engage in latching part receptacles 11, which together represent a receiving recess 12 for the latching device 10.

Wie der Figur 3 zu entnehmen ist, die den Steckverbinder 1 in einer Querschnittsdarstellung durch die Rastteile 4 zeigt, weist der erfindungsgemäße Steckverbinder 1 in dem dargestellten Ausführungsbeispiel in Umfangsrichtung der Innenwand 13 drei mit gleichmäßigem Abstand zueinander angeordnete Rastteile 4 auf. Deutlich zu erkennen sind in dieser Figur auch die drei Rastteileaufnahmen 11, in denen die Rastteile 4 angeordnet sind. Ein solches Rastteil 4 ist in der Figur 4 vergrößert alleine dargestellt. Es weist ein zentrales Abstützelement 14 auf, das wie in der Figur 1 sichtbar, den Isolierkörper 3 in dem Gehäuseabschnitt 5 verrastet und in axialer Richtung fixiert. Das Abstützelement 14 ist als Rasthaken ausgebildet. Wie die Figur 3 außerdem zeigt, sind die Rastteile 4 schalenförmig ausgeführt und erstrecken sich in axialer Richtung des Gehäuseabschnittes 5 geradlinig und in Umfangsrichtung des Gehäuseabschnittes 5 gekrümmt. Dies gilt ebenso für das Abstützelement 14. Wie der Figur 4 zu entnehmen ist, entspricht die Krümmung der Rastteile 4 der gewölbten Kontur der Innenwand 13 des Gehäuseabschnittes 5. Die Figur 4 zeigt auch, dass die Rastteileaufnahmen 11 entsprechend geformt und gegenüber der Innenwand 13 zurückgesetzt sind.Again FIG. 3 can be seen, which shows the connector 1 in a cross-sectional view through the locking parts 4, the connector 1 according to the invention in the illustrated embodiment in the circumferential direction of the inner wall 13 has three equally spaced locking parts 4. Clearly visible in this figure, the three locking part receptacles 11, in which the locking parts 4 are arranged. Such a locking part 4 is in the FIG. 4 shown enlarged alone. It has a central support element 14, which, as in the FIG. 1 visible, the insulating body 3 is locked in the housing section 5 and fixed in the axial direction. The support element 14 is designed as a latching hook. As the FIG. 3 also shows, the locking parts 4 are designed shell-shaped and extend in the axial direction of the housing portion 5 straight and curved in the circumferential direction of the housing portion 5. This also applies to the support element 14. Like the FIG. 4 can be seen, corresponds to the curvature of the locking parts 4 of the curved contour of the inner wall 13 of the housing section 5. Die FIG. 4 also shows that the latching part receptacles 11 are correspondingly shaped and set back relative to the inner wall 13.

Deutlich zu erkennen sind in der Figur 3 zudem, dass die Rastteilaufnahmen 11 in Umfangsrichtung seitlich sich axial erstreckende Hinterschnitte 15 aufweisen sowie Einschubschienen 16 für die Rastteile 4. Die Rastteileaufnahmen 11 sind zu der Steckseite 7 des Gehäuseabschnittes 5 hin offen ausgebildet und erstrecken sich gemäß den Figuren 1, 2 von der Steckseite 7 bis kurz vor die Anschlussseite 8 des Gehäuseabschnittes 5. Die Rastteile 4 sind mit ihren axialen Seitenrändern 17 mit den Einschubschienen 16 in Eingriff, wobei die Rastteile 4 an den Seitenrändern 17 in der Figur 4 sichtbare Rastmittel 29 zum Verrasten der Rastteile 4 mit den Rastteileaufnahmen 11 aufweisen, die insbesondere mit den Hinterschnitten 15 zusammen wirken. Um das Verrasten zu ermöglichen, sind die Seitenränder 17 in radialer Richtung federnd ausgebildet. Die Rastteile 4 liegen dabei derart vertieft in den Rastteileaufnahmen 11 ein, dass nur die Abstützelemente 14 über die Innenwand 13 des Gehäuseabschnittes 5 vorstehen.Clearly visible in the FIG. 3 In addition, that the locking part receptacles 11 in the circumferential direction laterally have axially extending undercuts 15 and slide rails 16 for the locking parts 4. The locking part 11 recordings formed open to the mating side 7 of the housing portion 5 and extend according to the FIGS. 1 . 2 from the plug side 7 to just before the connection side 8 of the housing section 5. The locking parts 4 are with their axial side edges 17 with the slide rails 16 into engagement, wherein the locking parts 4 at the side edges 17 in the FIG. 4 have visible locking means 29 for locking the locking parts 4 with the Rastteileaufnahmen 11, which act in particular with the undercuts 15 together. In order to enable the locking, the side edges 17 are resiliently formed in the radial direction. The latching parts 4 lie in such a deepened in the Rastteileaufnahmen 11 that only the support members 14 protrude beyond the inner wall 13 of the housing portion 5.

Die Rastteile 4 sind, wie der Figur 4 zu entnehmen ist, an dem der Steckseite 7 des Gehäuseabschnittes 5 zugeordneten vorderen Ende an zwei Umfangsabschnitten 18 dünnwandiger als an dem der Anschlussseite 8 zugeordneten hinteren Ende ausgebildet. Dabei ist das vordere Ende des jeweiligen Umfangsabschnitts 18 nach vorne offen ausgebildet, so dass eine Axialausnehmung 19 vorhanden ist, die sich bis zu dem jeweiligen Abstützelement 14 von außen zugänglich erstreckt. Durch die Axialausnehmung 19 hindurch kann der Isolierkörper 3, gemäß der Figur 5b, von dem Gehäuseabschnitt 5 mittels des in der Figur 5 dargestellten Entriegelungswerkzeuges 9 gelöst werden.The locking parts 4 are, like the FIG. 4 can be seen, formed at the plug-side 7 of the housing portion 5 associated front end at two peripheral portions 18 thin-walled than at the terminal side 8 associated rear end.
