Description

Die Erfindung betrifft eine elektrische Steckverbindung aus zwei in einer Steckrichtung miteinander zu verbindenden Bauteilen mit elektrischen Kontakten. Ein erstes Bauteil dieser Steckverbindung ist als Stecker und ein zweites Bauteil dieser Steckverbindung ist als Buchse ausgebildet. Zwischen den Bauteilen ist eine Rastvorrichtung zur mechanischen Sicherung der Steckverbindung vorgesehen, wobei die Rastvorrichtung aus einem an dem ersten Bauteil gehaltenen Rastelement und einer in dem zweiten Bauteil ausgebildeten Rastvertiefung gebildet ist. Das Rastelement greift bei zusammengesteckter Steckverbindung in die Rastvertiefung ein und verrastet die Steckverbindung mechanisch gegen unbeabsichtigtes Lösen. Über ein auf das Rastelement wirkendes Betätigungselement kann die Verrastung durch Ausheben des Rastelementes aus der Rastvertiefung gelöst werden. Hierzu wird das Betätigungselement relativ zum Bauteil bewegt.The invention relates to an electrical plug connection comprising two components with electrical contacts that are to be connected to one another in a plugging direction. A first component of this plug connection is designed as a plug and a second component of this plug connection is designed as a socket. A locking device for mechanically securing the plug connection is provided between the components, the locking device being formed from a locking element held on the first component and a locking recess formed in the second component. When the plug connection is plugged together, the locking element engages in the locking recess and mechanically locks the plug connection to prevent it from being accidentally released. The locking can be released by lifting the locking element out of the locking recess using an actuating element acting on the locking element. To do this, the actuating element is moved relative to the component.

Derartige Steckverbindungen für elektrische Leitungen werden auch als Push-Pull Systeme bezeichnet und dienen dem einfachen Verbinden einer Steckverbindung mit mechanischer Sicherung. Die Rastvorrichtung wird über einen typischen 90°-Hinterschnitt realisiert. Dabei ist nachteilig, dass bei einer auf die Steckverbindung wirkenden Zugkraft ein Lösen der Rastvorrichtung auftreten kann. Dieses Lösen erfolgt zwar zerstörungsfrei, jedoch wirken beim Lösen durch Zugkraft sehr hohe abrasive Kräfte auf die Bauteile, so dass nach einer erneuten Verriegelung nicht mehr die Haltekraft der mechanischen Sicherung erreicht werden kann wie im Originalzustand.Such plug connections for electrical cables are also known as push-pull systems and are used to easily connect a plug connection with mechanical security. The locking device is implemented using a typical 90° undercut. The disadvantage here is that the locking device can come loose if a tensile force is applied to the plug connection. Although this release is non-destructive, very high abrasive forces act on the components when the tensile force is released, so that after re-locking, the locking device cannot be the holding force of the mechanical lock can no longer be achieved than in the original condition.

Aus der US 3,639,980 A und der US 4,880,393 A sind elektrische Steckverbindungen bekannt, welche eine mechanische Verriegelung zwischen einem elektronischen Stecker und einer ortsfesten Steckdose zeigen.From the US 3,639,980 A and the US 4,880,393 A Electrical plug connections are known which show a mechanical locking between an electronic plug and a fixed socket.

Der Erfindung liegt die Aufgabe zugrunde, eine elektrische Steckverbindung mit einer zwischen den Bauteilen wirkenden Rastvorrichtung derart auszubilden, dass ein Lösen der Verrastung auch bei großen auf die Steckverbindung wirkenden Zugkräften verhindert ist.The invention is based on the object of designing an electrical plug connection with a locking device acting between the components in such a way that release of the locking mechanism is prevented even when large tensile forces act on the plug connection.

Nach der Erfindung wird die Aufgabe durch eine Steckverbindung nach Anspruch 1 gelöst. Bei dieser Steckverbindung ist an dem das Rastelement tragenden ersten Bauteil ein mechanisches Verriegelungselement ausgebildet ist, welches das in der Rastvertiefung des zweiten Bauteils liegende Rastelement in seiner Raststellung sicher verriegelt. Zum Aufheben der Verriegelung ist vorgesehen, dass das Rastelement relativ zu dem Verriegelungselement zu bewegen ist. Das Rastelement ist derart am ersten Bauteil gelagert, dass es entgegen der Steckrichtung zu bewegen ist.According to the invention, the object is achieved by a plug connection according to claim 1. In this plug connection, a mechanical locking element is formed on the first component carrying the locking element, which securely locks the locking element lying in the locking recess of the second component in its locking position. To release the locking, it is provided that the locking element is moved relative to the locking element. The locking element is mounted on the first component in such a way that it can be moved against the plugging direction.

Mit dieser erfindungsgemäßen Ausbildung wird erreicht, dass ein Lösen der Steckverbindung nur durch eine Axialverschiebung oder Drehung des Betätigungselementes möglich ist. Mit der Bewegung des Betätigungselementes kommt das Rastelement vom Verriegelungselement frei, so dass es radial nach innen in einen Freiraum ausgelenkt werden kann. Durch die radiale Verlagerung der Rastnase des Rastelementes nach innen wird die Verrastung aufgehoben. Aufgrund des zurückgelegten Axialweges des Rastelementes liegt dieses vom Verriegelungselement frei. Das Rastelement liegt mit einem axialen Abstand zum Verriegelungselement.With this design according to the invention, it is achieved that the plug connection can only be released by axial displacement or rotation of the actuating element. When the actuating element moves, the locking element is released from the locking element so that it can be deflected radially inwards into a free space. The locking is released by the radial displacement of the locking lug of the locking element inwards. Due to the axial path covered by the locking element, it is free from the locking element. The locking element is at an axial distance from the locking element.

Die erfindungsgemäße elektrische Steckverbindung ist derart ausgelegt, dass bei einer Zugbelastung der Steckverbindung entgegen der Steckrichtung das Verriegelungselement das Rastelement in die Rastvertiefung kraftbeaufschlagt, so dass ein Ausheben der Rastnase des Rastelementes aus der Rastvertiefung sicher blockiert ist.The electrical plug connection according to the invention is designed in such a way that when the plug connection is subjected to a tensile load opposite to the plug-in direction, the locking element applies force to the locking element in the locking recess so that lifting of the locking lug of the locking element out of the locking recess is safely blocked.

Vorzugsweise ist das Rastelement entgegen der Steckrichtung der Steckverbindung verschiebbar an dem ersten Bauteil gelagert. Durch die Axialbewegung des Rastelementes in Richtung der Längsachse der Steckverbindung kommt dieses von dem Verriegelungselement frei und kann radial zum Lösen der Rastvorrichtung nach innen verdrängt werden.Preferably, the locking element is mounted on the first component so that it can move against the direction of insertion of the plug connection. The axial movement of the locking element in the direction of the longitudinal axis of the plug connection causes it to be released from the locking element and can be displaced radially inwards to release the locking device.

In einer Ausbildung der Erfindung ist vorgesehen, dass eine Feder das Rastelement in einer Endlage hält. Bei verriegelter Steckverbindung liegt das Rastelement in seiner durch eine Feder bestimmten Endlage. In dieser Endlage liegt das Rastelement an dem Verriegelungselement vorzugsweise an.In one embodiment of the invention, a spring holds the locking element in an end position. When the plug connection is locked, the locking element is in its end position determined by a spring. In this end position, the locking element preferably rests against the locking element.

Das Verriegelungselement ist mit einer dem Rastelement zugewandt liegenden Anlagefläche ausgebildet. Die Anlagefläche ist insbesondere als schiefe Ebene vorgesehen.The locking element is designed with a contact surface facing the locking element. The contact surface is provided in particular as an inclined plane.

In Weiterbildung der Erfindung weist die Steckvorrichtung eine Längsachse auf, wobei die Anlagefläche des Verriegelungselementes mit der Längsachse der Steckverbindung einen in Steckrichtung öffnenden Winkel von 20° bis 80°, insbesondere 60° begrenzt. Die Wahl der Größe des Winkels bestimmt bei einer Zugbelastung der Steckverbindung die von der Verriegelung ausgeübte Kraft auf das Rastelement.In a further development of the invention, the plug device has a longitudinal axis, whereby the contact surface of the locking element defines an angle of 20° to 80°, in particular 60°, opening in the direction of insertion with the longitudinal axis of the plug connection. The choice of the size of the angle determines the force exerted by the locking mechanism on the locking element when the plug connection is subjected to a tensile load.

Vorteilhaft weist das Rastelement eine Gegenfläche auf. Die Gegenfläche liegt der Anlagefläche des Verriegelungselementes gegenüber oder an dieser an.The locking element advantageously has a counter surface. The counter surface lies opposite or against the contact surface of the locking element.

Das Rastelement ist als Rastzunge mit einer Rastnase ausgebildet. Die Rastvertiefung ist als in dem zweiten Bauteil ausgebildete Rastnut ausgebildet. Gemäß der Erfindung weist die Rastnase eine im Querschnitt V-förmige Grundform auf. Der Querschnitt der Rastvertiefung und der Querschnitt der Rastnase weisen insbesondere eine gleiche, zweckmäßig identische Form auf.The locking element is designed as a locking tongue with a locking lug. The locking recess is designed as a locking groove formed in the second component. According to the invention, the locking lug has a basic shape with a V-shaped cross section. The cross section of the locking recess and the cross section of the locking lug have in particular the same, expediently identical shape.

In der verrasteten Endstellung der Steckverbindung liegt der Querschnitt der Rastnase formgenau in dem Querschnitt der Rastvertiefung.In the locked final position of the plug connection, the cross-section of the locking lug lies precisely in the cross-section of the locking recess.

Die Rastvorrichtung ist vorteilhaft derart ausgebildet, dass der in die Rastvertiefung eingreifende Rastabschnitt des Rastelementes eine Rastfläche aufweist, die mit der Längsachse der Steckverbindung einen in Steckrichtung öffnenden Winkel von weniger als 90° aufweist.The locking device is advantageously designed such that the locking section of the locking element engaging in the locking recess has a locking surface which has an angle of less than 90° opening in the plug-in direction with the longitudinal axis of the plug connection.

Die erste Seitenwand 26a liegt in einer Ebene 27, die mit einer Längsachse 3 der Steckverbindung 7 einen zur Buchse 20 (zweites Bauteil 2) öffnenden Winkel 28a bestimmt. Die Seitenwand 26a der umlaufenden Rastnut 25 bildet einen Kegel, dessen Spitze auf der Längsmittelachse 3 der Steckverbindung 7 liegt. Der Winkel 28a, der im gezeigten Ausführungsbeispiel ein Kegelwinkel ist, hat vorzugsweise eine Größe von 90° bis 20°, insbesondere eine Größe von 60°. Die zweite Seitenwand 26b des V-förmigen Querschnitts der Rastvertiefung 24 liegt in einer Ebene 29, die mit der Längsachse 3 der Steckverbindung 7 einen zum Stecker 10 (erstes Bauteil 1) öffnenden Winkel 28b bestimmt. Die Seitenwand 26b der umlaufenden Rastnut 25 bildet einen weiteren Kegel, dessen Spitze auf der Längsachse 3 der Steckverbindung 7 liegt. Der Winkel 28b, der im gezeigten Ausführungsbeispiel ein Kegelwinkel ist, hat vorzugsweise eine Größe von 20° bis 60°, insbesondere eine Größe von 30°.A first side wall 26a of the V-shaped cross section of the locking recess 24 lies near the end 34 of the second component 2. The first side wall 26a lies in a plane 27 which, with a longitudinal axis 3 of the plug connection 7, defines an angle 28a opening to the socket 20 (second component 2). The side wall 26a of the circumferential locking groove 25 forms a cone whose tip lies on the longitudinal center axis 3 of the plug connection 7. The angle 28a, which is a cone angle in the embodiment shown, preferably has a size of 90° to 20°, in particular a size of 60°. The second side wall 26b of the V-shaped cross section of the locking recess 24 lies in a plane 29 which, with the longitudinal axis 3 of the plug connection 7, defines an angle 28b opening to the plug 10 (first component 1). The side wall 26b of the circumferential locking groove 25 forms a further cone, the tip of which lies on the longitudinal axis 3 of the plug connection 7. The angle 28b, which is a cone angle in the embodiment shown, preferably has a size of 20° to 60°, in particular a size of 30°.

Das vorzugsweise als Buchse 20 ausgebildete zweite Bauteil 2 weist eine Aufnahme 22 zur elektrischen Kontaktierung der elektrischen Verbindungsstifte 12 des als Stecker 10 ausgebildeten ersten Bauteils 1 auf. Zwischen der Aufnahme 22 und dem Grundkörper 21 des zweiten Bauteils 2 ist ein Ringspalt 30 ausgebildet, der zur Aufnahme der Steckerhülse 13 des ersten Bauteils 1 dient.The second component 2, preferably designed as a socket 20, has a receptacle 22 for electrically contacting the electrical connection pins 12 of the first component 1 designed as a plug 10. An annular gap 30 is formed between the receptacle 22 and the base body 21 of the second component 2, which serves to receive the plug sleeve 13 of the first component 1.

Das erste Bauteil 1 weist über den Umfang des Grundkörpers 11 verteilt mehrere Rastelemente 14 auf. Zur Funktion der erfindungsgemäßen Steckverbindung 7 ist ein Rastelement 14 ausreichend; vorteilhaft sind über den Umfang des zylindrischen Grundkörpers 10 sechs Rastelemente 14 vorgesehen, wie insbesondere Fig. 2A zeigt.The first component 1 has several locking elements 14 distributed over the circumference of the base body 11. One locking element 14 is sufficient for the function of the plug connection 7 according to the invention; advantageously, six locking elements 14 are provided over the circumference of the cylindrical base body 10, as in particular Fig. 2A shows.

Die Rastelemente 14 sind ausweislich Fig. 2A an einer Trägerhülse 15 gehalten, die einen äußeren, vorteilhaft umlaufenden Ringflansch 16 aufweist. Die Trägerhülse 15 ist zusammen mit den Rastelementen 14 auf dem Grundkörper 11 des ersten Bauteils 1 verschiebbar gehalten. Die Trägerhülse 15 ist auf dem zylindrischen Grundkörper 11 axial geführt. Die Trägerhülse 15 ist zwischen einem Umfangsflansch 17 und einer Ringschulter 18 des Grundkörpers 11 begrenzt verschiebbar. Zwischen dem Umfangsflansch 17 und dem Ringflansch 16 ist eine Feder 19 angeordnet. Die Feder 19 hält die Trägerhülse 15 in einer Endstellung an der Ringschulter 18 des Grundkörpers 11. Durch die Feder 19 nehmen die an der Trägerhülse 15 gehaltenen Rastelemente 14 eine in Fig. 1 dargestellte Endlage ein.The locking elements 14 are Fig. 2A held on a carrier sleeve 15, which has an outer, advantageously circumferential ring flange 16. The carrier sleeve 15 is held displaceably on the base body 11 of the first component 1 together with the locking elements 14. The carrier sleeve 15 is guided axially on the cylindrical base body 11. The carrier sleeve 15 is displaceable to a limited extent between a peripheral flange 17 and an annular shoulder 18 of the base body 11. A spring 19 is arranged between the peripheral flange 17 and the annular flange 16. The spring 19 holds the carrier sleeve 15 in an end position on the annular shoulder 18 of the base body 11. The spring 19 causes the locking elements 14 held on the carrier sleeve 15 to assume a Fig.1 shown end position.

Die Trägerhülse 15 ist über ein Betätigungselement 5 aus der in Fig. 1 gezeigten Endlage entgegen der Steckrichtung 4 der Steckverbindung 7 in Richtung ihrer Längsachse 3 zu verschieben. Das Betätigungselement 5 ist als Schiebehülse 6 ausgebildet, welche an dem ersten Bauteil 1 verschiebbar gehalten ist. Eine Ringschulter 38 der Schiebehülse 6 wirkt mit dem Ringflansch 16 der Trägerhülse 15 zusammen.The carrier sleeve 15 is removed via an actuating element 5 from the Fig.1 shown end position against the plug-in direction 4 of the plug connection 7 in the direction of its longitudinal axis 3. The actuating element 5 is designed as a sliding sleeve 6, which is held displaceably on the first component 1. An annular shoulder 38 of the sliding sleeve 6 interacts with the annular flange 16 of the carrier sleeve 15.

Das Rastelement 14 ist als Rastzunge 44 ausgebildet. Die Rastzunge 44 trägt eine Rastnase 42, die vorzugsweise am freien Ende 43 der Rastzunge 44 angeordnet ist. Die Rastnase 42 weist - bezogen auf den zylindrischen Grundkörper 11 des Steckers 10 - nach außen und greift - von innen nach außen - in die Rastvertiefung 24 am zweiten Bauteil 2 der Steckverbindung 7 ein.The locking element 14 is designed as a locking tongue 44. The locking tongue 44 has a locking lug 42, which is preferably arranged at the free end 43 of the locking tongue 44. The The locking lug 42 points outwards with respect to the cylindrical base body 11 of the plug 10 and engages - from the inside outwards - into the locking recess 24 on the second component 2 of the plug connection 7.

In der in Fig. 1 gezeigten Endlage der Rastzunge 14 liegt diese an einem Verriegelungselement 40 an. Das Verriegelungselement 40 ist an dem ersten Bauteil 1 vorgesehen. Vorzugsweise ist das Verriegelungselement 40 an dem Grundkörper 11 und/oder an der Steckerhülse 13 vorgesehen. Das Verriegelungselement 40 ist auf dem Außenumfang des Grundkörpers 11 und/oder der Steckerhülse 13 angeordnet. Zweckmäßig ist das Verriegelungselement 40 einteilig mit dem Grundkörper 11 und/oder der Steckerhülse 13 vorgesehen.In the Fig.1 In the end position shown of the locking tongue 14, it rests on a locking element 40. The locking element 40 is provided on the first component 1. The locking element 40 is preferably provided on the base body 11 and/or on the plug sleeve 13. The locking element 40 is arranged on the outer circumference of the base body 11 and/or the plug sleeve 13. The locking element 40 is expediently provided in one piece with the base body 11 and/or the plug sleeve 13.

Im gezeigten Ausführungsbeispiel ist das Verriegelungselement 40 im Übergangsbereich des Grundkörpers 11 zur Steckerhülse 13 ausgebildet. Jedem Rastelement 14 ist ein Verriegelungselement 40 zugeordnet. Das Verriegelungselement 40 liegt in der Endlage des Rastelementes 14 an diesem an. Im gezeigten Ausführungsbeispiel eines insbesondere als Rastzunge 44 mit einer Rastnase 42 ausgebildeten Rastelements 14 liegt in der gezeigten Ausführungsform der Erfindung das freie Ende 43 der Rastzunge 44 an dem Verriegelungselement 40 an. Wie in Fig. 2B dargestellt, bilden die den Rastelementen 14 zugeordneten Verriegelungselemente 40 am ersten Bauteil 1 eine gemeinsame umlaufende, äußere Ringschulter 41. Die Ringschulter 41 ist insbesondere einteilig mit der Steckerhülse 13 und/oder dem Grundkörper 11 ausgebildet.In the embodiment shown, the locking element 40 is formed in the transition area of the base body 11 to the plug sleeve 13. Each locking element 14 is assigned a locking element 40. The locking element 40 rests against the locking element 14 in the end position. In the embodiment shown of a locking element 14 designed in particular as a locking tongue 44 with a locking nose 42, the free end 43 of the locking tongue 44 rests against the locking element 40 in the embodiment of the invention shown. As in Fig. 2B As shown, the locking elements 40 assigned to the locking elements 14 form a common circumferential, outer annular shoulder 41 on the first component 1. The annular shoulder 41 is in particular formed in one piece with the plug sleeve 13 and/or the base body 11.

Das als Buchse 20 ausgebildete zweite Bauteil 2 weist eine insbesondere kegelstumpfförmige Einführschräge 32 auf. Die Einführschräge 32 ist insbesondere an der Einstecköffnung 31 des zweiten Bauteils 2 ausgebildet. Die Einführschräge 32 wirkt mit einem kegelstumpfförmigen Abschnitt 33 des ersten Bauteils 1 zusammen. Der kegelstumpfförmige Abschnitt 33 ist aus der umlaufenden Ringschulter 41 der Verriegelungselemente 40 und der an den Verriegelungselementen 40 anliegenden Rastnasen 42 zusammengesetzt. Die Mantelfläche des kegelstumpfförmigen Abschnitts 33 ist von einem Verriegelungselement 40 oder mehreren Verriegelungselementen 40 einerseits und von einem Rastelement 14 oder mehreren Rastelementen 14 andererseits zusammengesetzt. Im gezeigten Ausführungsbeispiel bilden die Rastnasen 42 der Rastelemente 14 Teile der Mantelfläche des kegelstumpfförmigen Abschnitts 33.The second component 2, designed as a bushing 20, has a particularly truncated cone-shaped insertion bevel 32. The insertion bevel 32 is designed in particular on the insertion opening 31 of the second component 2. The insertion bevel 32 interacts with a truncated cone-shaped section 33 of the first component 1. The truncated cone-shaped section 33 is composed of the circumferential annular shoulder 41 of the locking elements 40 and the locking lugs 42 resting on the locking elements 40. The outer surface of the truncated cone-shaped section 33 is a locking element 40 or several locking elements 40 on the one hand and a locking element 14 or several locking elements 14 on the other hand. In the embodiment shown, the locking lugs 42 of the locking elements 14 form parts of the outer surface of the frustoconical section 33.

Wie in Fig. 3 dargestellt, werden das erste Bauteil 1 und das zweite Bauteil 2 zum Zusammenfügen der Steckverbindung 7 in Steckrichtung 4 aufeinander zu bewegt. Die Steckerhülse 13 tritt in die Einstecköffnung 31 des zweiten Bauteils 2 ein und wird in der weiteren Bewegung in Steckrichtung 4 in den Ringspalt 30 eingeführt. Die beiden Bauteile 1 und 2 werden in Steckrichtung 4 weiter aufeinander zu bewegt. Dabei gleitet die Einführschräge 32 des zweiten Bauteils 2 (Buchse 21) auf den kegelstumpfförmigen Abschnitt 33 des ersten Bauteils 1 (Stecker 10) auf. Bei der weiteren Bewegung in Steckrichtung 4 schiebt sich die Einführschräge 31 auf den kegelstumpfförmigen Mantelabschnitt des Rastelementes 14 auf und verdrängt dieses axial entgegen der Steckrichtung 4 und radial nach innen. Zur Aufnahme der radial nach innen ausgelenkten Rastzunge 14 ist zwischen dem Verriegelungselement 40 und der Ringschulter 18 des Grundkörpers 11 ein Freiraum 45 ausgebildet. Der Freiraum 45 ist insbesondere als vertiefte Umfangsnut 46 oder Freistich im zylindrischen Grundkörper 11 des ersten Bauteils 1 ausgebildet ist.As in Fig.3 As shown, the first component 1 and the second component 2 are moved towards each other in the plug-in direction 4 to join the plug connection 7. The plug sleeve 13 enters the insertion opening 31 of the second component 2 and is inserted into the annular gap 30 during the further movement in the plug-in direction 4. The two components 1 and 2 are moved further towards each other in the plug-in direction 4. In the process, the insertion bevel 32 of the second component 2 (socket 21) slides onto the frustoconical section 33 of the first component 1 (plug 10). During the further movement in the plug-in direction 4, the insertion bevel 31 slides onto the frustoconical jacket section of the locking element 14 and displaces this axially against the plug-in direction 4 and radially inwards. To accommodate the radially inwardly deflected locking tongue 14, a free space 45 is formed between the locking element 40 and the annular shoulder 18 of the base body 11. The free space 45 is designed in particular as a recessed circumferential groove 46 or undercut in the cylindrical base body 11 of the first component 1.

Mit dem Auflaufen der Schrägfläche 31 auf den kegelstumpfförmigen Mantelabschnitt des Rastelementes 14 wird dieses zusammen mit der Trägerhülse 15 entgegen der Einsteckrichtung 4 des ersten Bauteils 1 axial verschoben. Die axiale Verschiebung des Rastelementes 14 zusammen mit der Trägerhülse 15 ist durch den Umfangsflansch 17 des Grundkörpers 11 des ersten Bauteils 1 begrenzt. Mit der Axialverschiebung kommt das Rastelement 14 vom Verriegelungselement 40 frei. Die Einführschräge 31 überfährt das in der Axialbewegung blockierte Rastelement 14, bis die Bauteile 1 und 2 vollständig ineinander eingesteckt sind, wie dies in Fig. 4 gezeigt ist. Nach dem Überfahren des Rastelementes 14 durch die Einführschräge 31 federt dieses aus dem Freiraum 45 in seine Ausgangslage zurück und verrastet die beiden Bauteile 1 und 2 der Steckverbindung 7 miteinander.When the inclined surface 31 runs onto the frustoconical casing section of the locking element 14, the latter is axially displaced together with the carrier sleeve 15 against the insertion direction 4 of the first component 1. The axial displacement of the locking element 14 together with the carrier sleeve 15 is limited by the circumferential flange 17 of the base body 11 of the first component 1. With the axial displacement, the locking element 14 is released from the locking element 40. The insertion bevel 31 moves over the locking element 14, which is blocked in the axial movement, until the components 1 and 2 are completely inserted into one another, as shown in Fig.4 After the locking element 14 has passed through the insertion bevel 31, it springs out of the free space 45 into its original position and locks the two components 1 and 2 of the connector 7 together.

Mit dem Zurückfedern des Rastelements 14 greift die Rastnase 42 der Rastzunge 44 in die Rastvertiefung 24 ein. Das erste Bauteil 1 und das zweite Bauteil 2 sind durch die Rastvorrichtung aus dem Rastelement 14 und dem Gegenrastelement 23 mechanisch gesichert verbunden.When the locking element 14 springs back, the locking lug 42 of the locking tongue 44 engages in the locking recess 24. The first component 1 and the second component 2 are mechanically secured by the locking device consisting of the locking element 14 and the counter-locking element 23.

Die Rastnase 42 ist im Querschnitt V-förmig ausgebildet. Die Rastnase 42 ist im Querschnitt der V-förmigen Grundform der Rastvertiefung 24 angeglichen. Der Querschnitt der Rastnase 42 greift formgenau in den Querschnitt der Rastvertiefung 24 ein. Insbesondere sind der Querschnitt der Rastnase 42 und der Querschnitt der Rastvertiefung 24 als Positiv und Negativ einander angepasst.The locking lug 42 is V-shaped in cross section. The locking lug 42 is adapted in cross section to the V-shaped basic shape of the locking recess 24. The cross section of the locking lug 42 engages precisely in the cross section of the locking recess 24. In particular, the cross section of the locking lug 42 and the cross section of the locking recess 24 are adapted to each other as positive and negative.

In dieser in Fig. 4 gezeigten verrasteten Endstellung der erfindungsgemäßen elektrischen Steckverbindung 7 liegt das Rastelement 14 in seiner durch die Feder 19 bewirkten Endlage. In dieser Endlage liegt das Rastelement 14 an dem Verriegelungselement 40 des ersten Bauteils 1 an. In dieser Endlage liegt im gezeigten Ausführungsbeispiel das freie Ende 43 der Rastzunge 44 am Verriegelungselement 40 an. In Fig. 5 ist in der vergrößerten Darstellung der Einzelheit V die Lage und das Zusammenwirken des Rastelementes 14 mit dem Verriegelungselement 40 vergrößert dargestellt.In this Fig.4 In the locked end position of the electrical plug connection 7 according to the invention shown, the locking element 14 is in its end position caused by the spring 19. In this end position, the locking element 14 rests on the locking element 40 of the first component 1. In this end position, in the embodiment shown, the free end 43 of the locking tongue 44 rests on the locking element 40. In Fig.5 In the enlarged view of detail V, the position and interaction of the locking element 14 with the locking element 40 is shown enlarged.

Die eine Seitenwand 26a der im Querschnitt V-förmigen Rastvertiefung 24 liegt unter einem Winkel 28a zur Längsachse 3 der Bauteile 1 und 2. Entsprechend der Winkellage der Seitenwand 26a zur Längsachse 3 ist die Rastnase 42 mit einer Anlagefläche 47 ausgebildet. Die Anlagefläche 47 liegt insbesondere parallel zur Seitenwand 26a der V-förmigen Rastvertiefung 24. Aufgrund der zylindrischen Ausbildung der Bauteile 1 und 2 bildet die Seitenwand 26a der Rastvertiefung 24 ebenso wie die Anlagefläche 47 der Rastnase 42 eine kegelstumpfförmige Mantelfläche. Die an die Anlagefläche 47 anschließende radiale Außenfläche 48 der Rastnase 42 ist der Winkellage der Seitenwand 26b der V-förmigen Rastvertiefung 24 entsprechend ausgebildet. Die radiale Außenfläche 48 liegt parallel zur Seitenwand 26b der V-förmigen Rastvertiefung 24.One side wall 26a of the locking recess 24, which is V-shaped in cross section, is at an angle 28a to the longitudinal axis 3 of the components 1 and 2. The locking lug 42 is designed with a contact surface 47 in accordance with the angular position of the side wall 26a to the longitudinal axis 3. The contact surface 47 is in particular parallel to the side wall 26a of the V-shaped locking recess 24. Due to the cylindrical design of the components 1 and 2, the side wall 26a of the locking recess 24, as well as the contact surface 47 of the locking lug 42, form a frustoconical surface. The radial outer surface 48 of the locking lug 42 adjoining the contact surface 47 is the angular position of the side wall 26b of the V-shaped locking recess 24 is designed accordingly. The radial outer surface 48 lies parallel to the side wall 26b of the V-shaped locking recess 24.

Das freie Ende 43 des Rastelementes 14 bzw. der Rastzunge 44 liegt mit einer Gegenfläche 49 einer Anlagefläche 50 des Verriegelungselementes 40 gegenüber. Vorzugsweise liegt die Gegenfläche 49 des Rastelementes 14 an der Anlagefläche 50 des Verriegelungselementes 40 an.The free end 43 of the locking element 14 or the locking tongue 44 lies with a counter surface 49 opposite a contact surface 50 of the locking element 40. Preferably, the counter surface 49 of the locking element 14 lies against the contact surface 50 of the locking element 40.

Die Anlagefläche 50 des Verriegelungselementes 40 ist als schiefe Ebene 51 ausgebildet. Die um die Längsachse 3 umlaufende Anlagefläche 50 bildet einen Kegelstumpf mit einem Öffnungswinkel 52 von 20° bis 80°. Vorteilhaft hat der Öffnungswinkel 52 eine Größe von 60°.The contact surface 50 of the locking element 40 is designed as an inclined plane 51. The contact surface 50 running around the longitudinal axis 3 forms a truncated cone with an opening angle 52 of 20° to 80°. The opening angle 52 is advantageously 60°.

Durch die erfindungsgemäße Ausbildung der elektrischen Steckverbindung 7 wird erreicht, dass bei einer Zugbelastung der Steckverbindung 7 auf die Enden 8, 9 (Fig. 1) der Bauteile 1, 2 der Steckverbindung 7 entgegen der Steckrichtung 4 das Verriegelungselement 40 das Rastelement 14 in der Rastvertiefung 24 hält. Bevorzugt wird bei einer Zugbelastung entgegen der Steckrichtung 4 das Rastelement 14 durch das Verriegelungselement 40 in die Rastvertiefung 24 kraftbeaufschlagt. Ein Ausheben des Rastelementes 14 bzw. der Rastnase 42 der Rastzunge 44 aus der Rastvertiefung 24 des zweiten Bauteils 2 bzw. der Buchse 20 durch Zugbelastung ist sicher verhindert. Wird an dem einen und/oder an dem anderen Ende 8, 9 der Bauteile 1, 2 entgegen der Steckrichtung 4 gezogen, so wird das Verriegelungselement 40 das in der Rastvertiefung 24 des zweiten Bauteils 2 liegende Rastelement 24 in seiner Raststellung verriegeln. Ein Lösen der Verrastung aufgrund einer erhöhten Zugkraft an den Enden 8, 9 (Fig. 1) der Bauteile 1, 2 der Steckverbindung 7 ist verhindert. Zum Aufheben der erfindungsgemäßen Verriegelung muss das Rastelement 14 relativ zu dem Verriegelungselement 40 entgegen der Steckrichtung 4 axial bewegt werden. Bei einem z. B. über die Schiebehülse 6 bewirkten Zurückziehen des Rastelementes 14 von dem Verriegelungselement 40 wird das Rastelement 14 zur radialen Auslenkung freigegeben, so dass es radial nach innen in den Freiraum 45 ausweichen kann. Durch die Axialbewegung entgegen der Steckrichtung 4 gleitet die eine schiefe Ebene bildende Anlagefläche 47 der Rastnase 42 auf der Seitenwand 26a und erfährt eine radial gerichtete Kraft nach innen, wodurch die Rastnase 42 aus der Rastvertiefung 24 frei kommt und die Rastvorrichtung gelöst wird. Die Rastvorrichtung öffnet. Der das erste Bauteil 1 bildende Stecker 10 kann aus dem die Buchse 20 bildenden zweiten Bauteil 2 herausgezogen werden.The inventive design of the electrical plug connection 7 ensures that when the plug connection 7 is subjected to a tensile load on the ends 8, 9 ( Fig.1 ) of the components 1, 2 of the plug connection 7 against the plugging direction 4, the locking element 40 holds the locking element 14 in the locking recess 24. Preferably, in the case of a tensile load against the plugging direction 4, the locking element 14 is subjected to force by the locking element 40 into the locking recess 24. Lifting the locking element 14 or the locking lug 42 of the locking tongue 44 out of the locking recess 24 of the second component 2 or the socket 20 due to tensile load is reliably prevented. If one and/or the other end 8, 9 of the components 1, 2 is pulled against the plugging direction 4, the locking element 40 will lock the locking element 24 lying in the locking recess 24 of the second component 2 in its locking position. Release of the locking due to an increased tensile force at the ends 8, 9 ( Fig.1 ) of the components 1, 2 of the plug connection 7 is prevented. To release the locking according to the invention, the locking element 14 must be moved axially relative to the locking element 40 against the plugging direction 4. When the locking element 14 is pulled back from the locking element 40, for example via the sliding sleeve 6, the locking element 14 is released for radial deflection so that it can escape radially inwards into the free space 45. Due to the axial movement against the plug-in direction 4, the contact surface 47 of the locking lug 42, which forms an inclined plane, slides on the side wall 26a and experiences a radially directed force inwards, whereby the locking lug 42 is released from the locking recess 24 and the locking device is released. The locking device opens. The plug 10 forming the first component 1 can be pulled out of the second component 2 forming the socket 20.

Die Darstellung des weiteren Ausführungsbeispiels in den Figuren 6 bis 8 entspricht im Grundaufbau denen der Figuren 1 bis 5. Für gleiche Teile sind gleiche Bezugszeichen verwendet.The representation of the further embodiment in the Figures 6 to 8 corresponds in basic structure to those of the Figures 1 to 5 . The same reference symbols are used for the same parts.

Im Ausführungsbeispiel nach den Figuren 6 bis 8 ist eine gegenüber dem Ausführungsbeispiel der Figuren 1 bis 5 geänderte Kopplung des als Schiebehülse 6 ausgebildeten Betätigungselementes 5 mit der die Rastelemente 14 aufweisenden Trägerhülse 15 vorgesehen. Der Ringflansch 16 wirkt nicht nur mit der Ringschulter 38 der Schiebehülse 6 zusammen. Im Ausführungsbeispiel nach den Figuren 6 bis 8 liegt der Ringflansch 16 der Trägerhülse 15 zwischen der Ringschulter 38 und einer Innenschulter 39. Die Ringschulter 38 und die Innenschulter 39 liegen in Axialrichtung der Schiebehülse 6 mit Abstand zueinander und begrenzen eine Aufnahmenut 35. In dieser Aufnahmenut 35 ist der Ringflansch 16 der Trägerhülse 15 gehalten. Dadurch ist das als Schiebehülse 6 ausgebildete Betätigungselement 5 in beiden Axialrichtungen mit dem Rastelement 14 verbunden.In the example according to the Figures 6 to 8 is a comparison with the embodiment of the Figures 1 to 5 modified coupling of the actuating element 5 designed as a sliding sleeve 6 with the carrier sleeve 15 having the locking elements 14 is provided. The ring flange 16 not only interacts with the ring shoulder 38 of the sliding sleeve 6. In the embodiment according to the Figures 6 to 8 the ring flange 16 of the carrier sleeve 15 lies between the ring shoulder 38 and an inner shoulder 39. The ring shoulder 38 and the inner shoulder 39 are spaced apart from one another in the axial direction of the sliding sleeve 6 and delimit a receiving groove 35. The ring flange 16 of the carrier sleeve 15 is held in this receiving groove 35. As a result, the actuating element 5 designed as a sliding sleeve 6 is connected to the locking element 14 in both axial directions.

Beim Zusammenstecken der Steckverbindung 7 wird die Einführschräge 31 des zweiten Bauteils 2 auf den kegelstumpfförmigen Abschnitt 33 des ersten Bauteils 1 aufgleiten, so wie dies vorstehend beschrieben ist. Beim axialen Zurückdrängen des Rastelementes 14 beim Aufgleiten der Einführschräge 32 der Einstecköffnung 31 wird die Schiebehülse 6 zusammen mit dem Rastelement 14 axial entgegen der Steckrichtung 4 verschoben. Die axiale Verschiebung des Rastelementes 14 zusammen mit der Trägerhülse 15 ist durch den Umfangsflansch 17 des Grundkörpers 11 des ersten Bauteils 1 begrenzt. Diese Zwischenstellung ist in Fig. 7 dargestellt.When the plug connection 7 is plugged together, the insertion bevel 31 of the second component 2 will slide onto the frustoconical section 33 of the first component 1, as described above. When the locking element 14 is pushed back axially when the insertion bevel 32 of the insertion opening 31 slides onto it, the sliding sleeve 6 is displaced axially against the plugging direction 4 together with the locking element 14. The axial displacement of the locking element 14 together with the carrier sleeve 15 is limited by the peripheral flange 17 of the base body 11 of the first component 1. This intermediate position is in Fig.7 shown.

Bei der weiteren Bewegung in Steckrichtung 4 überfährt die Einführschräge 31 die Rastnase 42 des axial feststehenden Rastelementes 14, wobei das Rastelement 14 radial nach innen in den Freiraum 45 verdrängt wird. Sobald die Rastnase 42 axial überfahren ist, federt diese aus dem Freiraum 45 radial nach außen und greift in die Rastvertiefung 24 des zweiten Bauteils 2 ein. Vorteilhaft zugleich wird das Rastelement 14 durch die Feder 19 axial auf das Verriegelungselement 40 zu bewegt, bis die axiale Endlage des Rastelementes 14 erreicht ist. In dieser Endlage liegt vorteilhaft das freie Ende 43 des Rastelementes 14 an der Anlagefläche 50 des Verriegelungselementes 40 an. Die Rastnase 42 des Rastelementes 14 ist in der Rastvertiefung 24 verriegelt gehalten.During further movement in the plug-in direction 4, the insertion bevel 31 passes over the locking lug 42 of the axially fixed locking element 14, whereby the locking element 14 is displaced radially inwards into the free space 45. As soon as the locking lug 42 is axially passed over, it springs radially outwards from the free space 45 and engages in the locking recess 24 of the second component 2. At the same time, the locking element 14 is advantageously moved axially towards the locking element 40 by the spring 19 until the axial end position of the locking element 14 is reached. In this end position, the free end 43 of the locking element 14 advantageously rests on the contact surface 50 of the locking element 40. The locking lug 42 of the locking element 14 is held locked in the locking recess 24.

Durch die Kopplung der Schiebehülse 6 in beiden axialen Bewegungsrichtungen des Rastelementes 14 ist die Axialbewegung des Rastelementes 14 durch den Benutzer über die Axialstellung der Schiebehülse 6 optisch erkennbar. Anhand der Axialstellung der Schiebehülse 6 in der Lage nach Fig. 8 kann der Benutzer eine ordnungsgemäße Verrastung und Verriegelung der Steckverbindung erkennen.By coupling the sliding sleeve 6 in both axial directions of movement of the locking element 14, the axial movement of the locking element 14 can be visually recognized by the user via the axial position of the sliding sleeve 6. Based on the axial position of the sliding sleeve 6 in the position according to Fig.8 the user can see that the connector is properly engaged and locked.

Im Ausführungsbeispiel nach Fig. 9 ist eine Rastvertiefung 24 im zweiten Bauteil 2 gezeigt, welche vorteilhaft als umlaufende innere Rastnut 25 im Grundkörper 21 ausgebildet ist. Die im Ausführungsbeispiel nach Fig. 9 ausgebildete Rastnut 25 hat einen U-förmigen Querschnitt. Die Seitenwände 26a' und 26b' bilden Ringflächen, die in Ebenen liegen, die zu der Längsmittelachse 3 der Steckverbindung 7 in einem rechten Winkel liegen. Die Längsmittelachse 3 der Steckverbindung 7 steht senkrecht auf den gedachten Ebenen der Seitenwände 26a' und 26b'.In the example according to Fig.9 a locking recess 24 is shown in the second component 2, which is advantageously designed as a circumferential inner locking groove 25 in the base body 21. The locking recess 24 shown in the embodiment according to Fig.9 The locking groove 25 has a U-shaped cross-section. The side walls 26a' and 26b' form annular surfaces which lie in planes which are at a right angle to the longitudinal center axis 3 of the plug connection 7. The longitudinal center axis 3 of the plug connection 7 is perpendicular to the imaginary planes of the side walls 26a' and 26b'.

Das Verriegelungselement 40 ist als Außenring 55 insbesondere am Ende der Steckerhülse 13 ausgebildet. Die am Verriegelungselement 40 vorgesehene Anlagefläche 50 für das freie Ende 43 der Rastzunge 14 liegt unter einem Winkel 52, wie er in Fig. 5 dargestellt ist. Der Anlagefläche 50 des Verriegelungselementes 40 liegt die Gegenfläche 49 des Rastelementes 14 gegenüber; wie in Fig. 5 dargestellt, liegt die Gegenfläche 49 vorzugsweise parallel zur Anlagefläche 50. Die Rastnase 42 des Rastelementes 14 ist im Querschnitt V-förmig ausgebildet, so dass der zur Längsachse 3 senkrechten Seitenwand 26a'eine Anlagefläche 47 gegenüberliegt, die unter einem Winkel 28a zur Längsachse 3 liegt, wie dies in Fig. 5 gezeigt ist.The locking element 40 is designed as an outer ring 55, in particular at the end of the connector sleeve 13. The contact surface 50 provided on the locking element 40 for the free end 43 of the locking tongue 14 is at an angle 52 as shown in Fig.5 The contact surface 50 of the locking element 40 is opposite the counter surface 49 of the locking element 14; as shown in Fig.5 shown, the counter surface 49 is preferably parallel to the contact surface 50. The locking lug 42 of the locking element 14 is V-shaped in cross section, so that the side wall 26a' perpendicular to the longitudinal axis 3 is opposite a contact surface 47 which is at an angle 28a to the longitudinal axis 3, as shown in Fig.5 is shown.

Die Funktionsweise der Steckverbindung nach dem Ausführungsbeispiel nach Fig. 9 entspricht den vorstehend beschriebenen Ausführungsbeispielen. Zum Lösen der Steckverbindung wird die Schiebehülse 6 entgegen der Steckrichtung 4 axial bewegt, wodurch das Rastelement 14 entgegen der Steckrichtung 4 axial auf dem Grundkörper 11 verschoben wird. Dadurch kommt die Gegenfläche 49 der Rastzunge 14 von der Anlagefläche 50 des Verriegelungselementes 40 frei. Durch die Axialbewegung entgegen der Steckrichtung 4 gleitet die eine schiefe Ebene bildende Anlagefläche 47 auf der Nutkante der Rastvertiefung 24 und erfährt eine radial gerichtete Kraft nach innen, wodurch die Rastnase 42 aus der Rastvertiefung 24 freikommt und die Rastvorrichtung gelöst wird. Das Verriegeln der Steckverbindung 7 erfolgt wie zu den anderen Ausführungsbeispielen beschrieben.The functionality of the connector according to the example shown in Fig.9 corresponds to the embodiments described above. To release the plug connection, the sliding sleeve 6 is moved axially against the plug direction 4, whereby the locking element 14 is moved axially on the base body 11 against the plug direction 4. As a result, the counter surface 49 of the locking tongue 14 is released from the contact surface 50 of the locking element 40. Due to the axial movement against the plug direction 4, the contact surface 47, which forms an inclined plane, slides on the groove edge of the locking recess 24 and experiences a radially directed force inwards, whereby the locking lug 42 is released from the locking recess 24 and the locking device is released. The locking of the plug connection 7 takes place as described for the other embodiments.
