Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft einen stiftseitigen Stecker und einen buchsenseitigen Stecker zur elektrischen Verbindung miteinander nach dem Oberbegriff von Anspruch 1.The present invention relates to a plug-side connector and a socket-side connector for electrical connection with one another according to the preamble of claim 1.

STAND DER TECHNIKSTATE OF THE ART

Zum Herstellen von elektrischen und/oder elektronischen Verbindungen zwischen verschiedenen Bauteilen, Leitungen oder dergleichen sind Steckverbindungen bekannt, die aus einem Steckelement und einem Buchsenelement bestehen. Oftmals weist das Steckelement dabei ein oder mehrere Kontaktelemente auf, welche in einen oder mehrere entsprechenden Buchsenkontakte im Buchsenelement eingeführt werden. Bei ganz oder teilweise durch elektrischen Strom angetriebenen Elektro- beziehungsweise Hybridfahrzeugen werden sehr grosse Ströme und/oder Spannungen über die Steckelemente und somit über deren Kontaktelemente übertragen.For the production of electrical and / or electronic connections between different components, lines or the like, plug connections are known which consist of a plug element and a socket element. Often the plug element has one or more contact elements which are inserted into one or more corresponding socket contacts in the socket element. In the case of electric or hybrid vehicles driven entirely or partially by electric current, very large currents and / or voltages are transmitted via the plug-in elements and thus via their contact elements.

Wegen der hohen Ströme beziehungsweise Spannungen werden besonders hohe Sicherheitsanforderungen an die Steckelemente gestellt, um eine unbeabsichtigte Berührung der Kontaktelemente durch einen menschlichen Finger zu verhindern. Für eine entsprechende Prüfung kann ein sogenannter Prüffinger verwendet werden, welcher einer vorgeschriebenen Norm IEC 60529 entspricht und mit einer vorgeschriebenen Prüfkraft gegen Abschnitte oder Öffnungen des Steckelements gedrückt wird, in welchen sich das oder die Kontaktelemente befinden. Dabei darf es zu keiner Berührung der stromführenden Abschnitte der Kontaktelemente durch den Prüffinger kommen.Because of the high currents or voltages, particularly high safety requirements are placed on the plug-in elements in order to prevent unintentional contact with the contact elements by a human finger. For a corresponding test, a so-called test finger can be used, which corresponds to a prescribed standard IEC 60529 and is pressed with a prescribed test force against sections or openings of the plug-in element in which the contact element or elements are located. The test finger must not come into contact with the current-carrying sections of the contact elements.

Aus dem Stand der Technik sind unterschiedliche Möglichkeiten bekannt, wie dass solch eine ungewollte Berührung durch einen Finger verhindert werden kann.Various possibilities are known from the prior art as to how such an unintentional touch by a finger can be prevented.

Beispielsweise ist aus der US 8 734 191 B2 ein Stecker mit einem Kontakt bekannt, wobei eine Isolationskappe auf dem Kontakt sowie seitliche Schutzhüllen vorhanden sind, welche den Kontakt auf allen Seiten umgeben.For example, from the US 8 734 191 B2 a plug with a contact is known, with an insulation cap on the contact and protective covers on the sides which surround the contact on all sides.

Die WO 2014/187908 offenbart einen Stecker, dessen Kontakt von einer Schutzhülle teilweise umgeben ist, sowie einen Stecker, bei welchem die Schutzhülle einstückig mit einer Isolationskappe für den Kontakt ausgebildet ist.The WO 2014/187908 discloses a plug, the contact of which is partially surrounded by a protective sheath, and a plug, in which the protective sheath is formed in one piece with an insulating cap for the contact.

Das Vorsehen von Schutzelementen zum Schutz vor Berührungen führt allerdings zu einem erhöhten Platzbedarf respektive Platzmangel, was insbesondere bei Steckern mit mehreren Kontaktelementen von Nachteil ist.However, the provision of protective elements to protect against contact leads to an increased space requirement or lack of space, which is a disadvantage in particular in the case of plugs with several contact elements.

DARSTELLUNG DER ERFINDUNGDISCLOSURE OF THE INVENTION

Aufgabe der vorliegenden Erfindung ist es daher, einen Stecker anzugeben, welcher die Nachteile des Standes der Technik überwindet. Insbesondere wird ein Stecker angegeben, welcher über eine kompakte Konstruktion verfügt. Eine weitere besonders bevorzugte Aufgabe ist es, einen Stecker anzugeben, welcher einen möglichst guten und konstanten elektrischen Kontakt vermittelt.The object of the present invention is therefore to provide a connector which overcomes the disadvantages of the prior art. In particular, a plug is specified which has a compact construction. Another particularly preferred object is to specify a plug which provides the best possible and constant electrical contact possible.

Erfindungsgemäss wird diese Aufgabe durch einen Stecker gemäss Anspruch 1 gelöst.According to the invention, this object is achieved by a plug according to claim 1.

Es wird gemäss Anspruch 1 ein stiftseitiger Stecker zur elektrischen Verbindung mit einem buchsenseitigen Stecker angegeben, aufweisend ein stiftseitiges Steckergehäuse mit einer Steckerbasis und einer Steckerwandung, einen elektrisch leitenden Kontaktstift mit einem freien Stiftende und einem basisseitigen Stiftende zur Befestigung des Kontaktstiftes am stiftseitigen Steckergehäuse, und ein Schutzelement, welches elektrisch isolierend ausgebildet ist. Das Schutzelement ist beabstandet vom Kontaktstift am stiftseitigen Steckergehäuse angeordnet.According to claim 1, a pin-side connector for electrical connection to a socket-side connector is specified, comprising a pin-side connector housing with a connector base and a connector wall, an electrically conductive contact pin with a free pin end and a base-side pin end for fastening the contact pin to the pin-side connector housing, and a Protective element which is designed to be electrically insulating. The protective element is arranged at a distance from the contact pin on the pin-side connector housing.

Das Schutzelement verhindert eine ungewollte Berührung des Kontaktstiftes durch einen Finger oder dergleichen.The protective element prevents unintentional contact with the contact pin by one Fingers or the like.

Durch den Abstand wird es zudem möglich, dass die gesamte Umfangsseite des Kontaktstiftes von einer Buchse elektrisch umgriffen wird.The spacing also makes it possible for a socket to electrically encompass the entire circumferential side of the contact pin.

Wie nachfolgend noch erläutert wird, kann der stiftseitige Stecker über einen oder mehrere Kontaktstifte verfügen, wobei dann vorzugsweise ein oder mehrere Schutzelemente vorgesehen sind. Vorzugsweise ist pro Kontaktstift ein Schutzelement angeordnet. Aussagen zu jeweils einem Kontaktstift beziehungsweise Schutzelement sind daher entsprechend für ein oder mehrere Kontaktstifte beziehungsweise Schutzelemente zu verstehen.As will be explained below, the pin-side connector can have one or more contact pins, in which case one or more protective elements are preferably provided. One protective element is preferably arranged per contact pin. Statements relating to one contact pin or protective element in each case are therefore to be understood accordingly for one or more contact pins or protective elements.

Vorzugsweise ist das Schutzelement separat vom Kontaktstift ausgebildet. In anderen Worten handelt es sich beim Schutzelement also um ein separat vom Kontaktstift ausgebildetes sowie separat angeordnetes Bauteil.The protective element is preferably formed separately from the contact pin. In other words, the protective element is a component that is formed separately from the contact pin and is arranged separately.

Vorzugsweise ist zwischen dem Schutzelement und dem Kontaktstift ein nicht mit Bauteilen ausgefüllter Raumbereich vorhanden. Das Schutzelement ist vorzugsweise derart beabstandet angeordnet, dass das Schutzelement eine Mantelfläche des Kontaktstiftes nicht berührt.A spatial area not filled with components is preferably present between the protective element and the contact pin. The protective element is preferably arranged at a distance in such a way that the protective element does not touch a lateral surface of the contact pin.

Der Kontaktstift ist vorzugsweise zylindrisch ausgebildet und erstreckt sich, ausgehend vom basisseitigen Stiftende in Richtung des freien Stiftendes, entlang einer entlang Mittelachse.The contact pin is preferably cylindrical and extends, starting from the base-side pin end in the direction of the free pin end, along a central axis.

Die Steckerwandung ist vorzugsweise elektrisch isolierend ausgebildet und beabstandet vom Kontaktstift am stiftseitigen Steckergehäuse angeordnet.The plug wall is preferably designed to be electrically insulating and is arranged at a distance from the contact pin on the plug housing on the pin side.

Die Steckerwandung, bevorzugterweise das gesamte stiftseitige Steckergehäuse, kann also ebenfalls aus einem elektrisch isolierenden Material ausgebildet sein, so dass das Schutzelement und auch die Steckerwandung gemeinsam einen elektrisch isolierenden Abdeckungsbereich für den Kontaktstift bilden. Die Steckerwandung kann als zusätzliches Schutzelement für den Kontaktstift verstanden werden.The connector wall, preferably the entire pin-side connector housing, can also be made of an electrically insulating material, so that the protective element and also the connector wall together form an electrically insulating cover area for the contact pin. The plug wall can be understood as an additional protective element for the contact pin.

Vorzugsweise ist das Schutzelement beabstandet von der Steckerwandung angeordnet. Das heisst, es ist bevorzugt, dass das Schutzelement beabstandet vom Kontaktstift sowie von der Steckerwandung am stiftseitigen Steckergehäuse angeordnet ist.The protective element is preferably arranged at a distance from the plug wall. This means that it is preferred that the protective element is arranged at a distance from the contact pin and from the plug wall on the plug housing on the pin side.

Die Steckerwandung erstreckt sich zumindest teilweise entlang einer Umfangsrichtung um den Kontaktstift herum. Die Steckerwandung steht dabei vorzugsweise derart zum Kontaktstift, dass ein Prüffinger nicht zwischen Steckerwand und Kontaktstift eingeschoben werden kann. Die Steckerwandung kann dabei im Querschnitt quer zur Mittelachse gesehen mindestens abschnittsweise kreissegmentförmig oder polygonartig oder rechteckig oder quadratisch oder aus einer Mischung davon ausgebildet sein. Vorzugsweise erstreckt sich die Steckerwandung kreiszylindrisch um die Mittelachse des Kontaktstiftes.The plug wall extends at least partially along a circumferential direction around the contact pin. The plug wall is preferably in relation to the contact pin in such a way that a test finger cannot be inserted between the plug wall and the contact pin. In this case, the plug wall, seen in cross section transversely to the central axis, can be formed at least in sections as a segment of a circle or polygon or rectangular or square or from a mixture thereof. The plug wall preferably extends in a circular-cylindrical manner around the central axis of the contact pin.

Das Schutzelement und die Steckerwandung sind vorzugsweise quasi konzentrisch oder exzentrisch um den Kontaktstift herum angeordnet. Bei einer konzentrischen Anordnung sind also das Schutzelement sowie die Steckerwandung jeweils in etwa demselben Abstand zum Kontaktstift entlang einer Umfangsrichtung um den Kontaktstift herum angeordnet. Bei einer exzentrischen Anordnung erstreckt sich die Steckerwandung um eine Achse, welche parallel zur Mittelachse des Kontaktstiftes liegt.The protective element and the plug wall are preferably arranged quasi concentrically or eccentrically around the contact pin. In the case of a concentric arrangement, the protective element and the plug wall are each arranged at approximately the same distance from the contact pin along a circumferential direction around the contact pin. In the case of an eccentric arrangement, the plug wall extends around an axis which is parallel to the central axis of the contact pin.

Die Steckerwandung kann umfangsseitig unterbrochen sein und das Schutzelement kann in einem Unterbruch der Steckerwandung oder im Bereich eines Unterbruches angeordnet sein. Die Steckerwandung kann über einen Unterbruch verfügen, wobei das Schutzelement in diesem einen Unterbruch angeordnet ist. Die Steckerwandung kann jedoch auch über mehrere Unterbrüche verfügen, so dass sich eine mehrteilige Steckerwandung um den Kontaktstift herum erstreckt, wobei die einzelnen Teile der Steckerwandung in einem Abstand zueinander angeordnet sind und das Schutzelement vorzugsweise zwischen zwei solcher Teile angeordnet ist.The plug wall can be interrupted on the circumference and the protective element can be arranged in an interruption in the plug wall or in the area of an interruption. The plug wall can have an interruption, the protective element being arranged in this one interruption. The plug wall can, however, also have several interruptions so that a multi-part plug wall extends around the contact pin, the individual parts of the plug wall being arranged at a distance from one another and the protective element preferably being arranged between two such parts.

Es ist aber auch denkbar, dass die Steckerwandung umfangsseitig nicht unterbrochen ist und stattdessen einstückig ausgebildet ist.However, it is also conceivable that the plug wall is not interrupted on the circumferential side and instead is formed in one piece.

Vorzugsweise weist das Schutzelement einen ersten Abschnitt auf, welcher entlang einer ersten Richtung orientiert ist, und einen zweiten Abschnitt auf, welcher entlang einer zweiten Richtung, insbesondere winklig zur ersten Richtung, orientiert ist und zur Verstärkung gegenüber einer Verformung des ersten Abschnitts vorgesehen ist. Im Falle einer Berührung des ersten Abschnitts des Schutzelementes durch einen Finger oder dergleichen sorgt also der zweite Abschnitt des Schutzelementes dafür, dass sich der erste Abschnitt, insbesondere das gesamte Schutzelement, aufgrund des Berührungsdruckes nicht verformt oder verbiegt.The protective element preferably has a first section, which is oriented along a first direction, and a second section, which is oriented along a second direction, in particular at an angle to the first direction, and is provided to reinforce a deformation of the first section. If the first section of the protective element is touched by a finger or the like, the second section of the protective element ensures that the first section, in particular the entire protective element, does not deform or bend due to the contact pressure.

Das Schutzelement ist bevorzugterweise im Wesentlichen U-förmig ausgebildet, wobei der erste Abschnitt durch einen Basisschenkel und der zweite Abschnitt durch zwei von diesem vorstehende, einander gegenüberliegende Seitenschenkel gebildet wird, wobei die Seitenschenkel dem Kontaktstift zugewandt sind. Die erste Richtung erstreckt sich dabei vorzugsweise senkrecht zur Mittelachse des Kontaktstiftes, und die zweite Richtung erstreckt sich vorzugsweise wiederum senkrecht zur ersten Richtung.The protective element is preferably essentially U-shaped, the first section being formed by a base limb and the second section being formed by two opposing side limbs protruding therefrom, the side limbs facing the contact pin. The first direction preferably extends perpendicular to the central axis of the contact pin, and the second direction preferably extends again perpendicular to the first direction.

Vorzugsweise erstrecken sich das Schutzelement, insbesondere der Basisschenkel und die Seitenschenkel, und/oder die Steckerwandung, ausgehend von der Steckerbasis in Richtung des freien Endes des Kontaktstiftes, im Wesentlichen entlang einer gesamten Länge des Kontaktstiftes.The protective element, in particular the base limb and the side limbs, and / or the plug wall preferably extend, starting from the plug base in the direction of the free end of the contact pin, essentially along an entire length of the contact pin.

Der Basisschenkel verfügt vorzugsweise über eine Breite quer zur Mittelachse gesehen, welche im Wesentlichen einer Breite des Kontaktstiftes entspricht. Das heisst, der Basisschenkel verdeckt im Wesentlichen eine gesamte Breite des Kontaktstiftes.The base leg preferably has a width, seen transversely to the central axis, which essentially corresponds to a width of the contact pin. This means that the base leg essentially covers an entire width of the contact pin.

Vorzugsweise weist das Schutzelement eine Länge auf, welche in Richtung der Mittelachse mindestens so lang ist, wie der Kontaktstift in die gleiche Richtung. Besonders bevorzugt ist das Schutzelement länger ausgebildet als der Kontaktstift.The protective element preferably has a length which is at least as long in the direction of the central axis as the contact pin in the same direction. The protective element is particularly preferably designed to be longer than the contact pin.

Es ist bevorzugt, dass sie Steckerwandung auf ihrer dem Kontaktstift zugewandten Innenfläche zwei parallele Wandflächen aufweist, welche parallelen Wandflächen bezüglich der sich ausgehend vom basisseitigen Stiftende in Richtung des freien Stiftendes entlang des Kontaktstifts erstreckenden Mittelachse einander gegenüberliegend angeordnet sind und/oder jeweils in einem gleichen Abstand von der Mittelachse angeordnet sind.It is preferred that the plug wall has two parallel wall surfaces on its inner surface facing the contact pin, which parallel wall surfaces are arranged opposite one another with respect to the central axis extending from the base-side pin end in the direction of the free pin end along the contact pin are and / or are each arranged at an equal distance from the central axis.

Die Steckerwandung weist vorzugsweise einen bogenförmigen Abschnitt auf, welcher die zwei parallelen Wandflächen bogenförmig miteinander verbindet. Die parallelen Wandflächen sind vorzugsweise rechteckig ausgebildet und erstrecken sich ausgehend vom basisseitigen Stiftende in Richtung des freien Stiftendes entlang der gesamten Länge der Steckerwandung.The plug wall preferably has an arcuate section which connects the two parallel wall surfaces to one another in an arcuate manner. The parallel wall surfaces are preferably rectangular and, starting from the pin end on the base side, extend in the direction of the free pin end along the entire length of the plug wall.

Vorzugseise ist das Schutzelement bezüglich der Steckerwandung in einer Ebene angeordnet, welche durch die Mittelachse und durch einen Bogenmittelpunkt des bogenförmigen Abschnitts festgelegt ist, und wobei das Schutzelement in dieser Ebene mittig zwischen den parallelen Wandflächen angeordnet ist.The protective element is preferably arranged with respect to the plug wall in a plane which is defined by the central axis and an arc center point of the arc-shaped section, and the protective element is arranged in this plane centrally between the parallel wall surfaces.

In anderen Worten ist das Schutzelement in einem Unterbruch der Steckerwandung angeordnet, wobei der bogenförmige Abschnitt der Steckerwandung auf der gegenüberliegenden Seite des Schutzelementes und die beiden parallelen Wandflächen auf den dem Schutzelement benachbarten Seiten der unterbrochenen Steckerwandung angeordnet sind.In other words, the protective element is arranged in an interruption in the plug wall, the curved section of the plug wall being arranged on the opposite side of the protective element and the two parallel wall surfaces being arranged on the sides of the interrupted plug wall adjacent to the protective element.

Die Steckerwandung kann aussenseitig oder innenseitig im Bereich der parallelen Wandflächen jeweils über Einrillungen verfügen. Diese Einrillungen können beispielsweise in Form von länglichen Schlitzen ausgebildet sein, welche sich ausgehend von der Steckerbasis in Richtung des freien Stiftendes im Wesentlichen entlang der gesamten Länge der Steckerwandung erstrecken. Durch die Einrillungen kann die Steckerwandung verstärkt werden. Dies insbesondere unter der Massgabe einer vereinfachten Herstellung mittels eines Spritzgiessverfahrens. Vorzugsweise sind die Einrillungen derart ausgebildet, dass keine übermässige Materialanhäufung bereitgestellt wird, wobei aber dennoch eine mechanisch feste Wandung bereitgestellt wird. Die Einrillungen haben insbesondere den Vorteil, dass die Steckerwandung bezüglich Querkräften, welche von einem Prüffinger aufgebracht werden, mechanisch robust ist.The plug wall can have grooves on the outside or inside in the area of the parallel wall surfaces. These grooves can be designed, for example, in the form of elongated slots which, starting from the plug base, extend in the direction of the free pin end essentially along the entire length of the plug wall. The plug wall can be reinforced by the grooves. This in particular with the proviso of a simplified production by means of an injection molding process. The grooves are preferably designed in such a way that no excessive accumulation of material is provided, but a mechanically solid wall is nevertheless provided. The grooves have the particular advantage that the plug wall is mechanically robust with regard to transverse forces which are applied by a test finger.

Vorzugsweise ist das Schutzelement und/oder die Steckerwandung einstückig mit dem Steckergehäuse ausgebildet und bilden eine Schutzanordnung für den Kontaktstift.The protective element and / or the plug wall is preferably formed in one piece with the plug housing and form a protective arrangement for the contact pin.

Vorzugsweise weist der stiftseitige Stecker zwei oder mehr Kontaktstifte auf, wobei jeder Kontaktstift jeweils ein Schutzelement, vorzugsweise ebenfalls mindestens jeweils ein Steckerwandung, insbesondere bevorzugt jeweils eine Schutzanordnung aufweist. Das heisst, für jeden Kontaktstift ist vorzugsweise eine Schutzanordnung vorgesehen.Preferably, the pin-side connector has two or more contact pins, each contact pin each having a protective element, preferably likewise at least one connector wall, particularly preferably each having a protective arrangement. This means that a protective arrangement is preferably provided for each contact pin.

Vorzugsweise werden dazu das Schutzelement und das Steckergehäuse in einem Herstellungsschritt, insbesondere gleichzeitig, einstückig gefertig.For this purpose, the protective element and the connector housing are preferably manufactured in one piece in one manufacturing step, in particular at the same time.

Es ist aber auch denkbar, dass das Schutzelement separat vom Steckergehäuse gefertigt wird und im Anschluss an die Fertigung beispielsweise durch eine entsprechende Ausnehmung in der Steckerbasis durch das stiftseitige Steckergehäuse hindurch geführt und darin befestigt wird. Weiter ist es denkbar, dass das Schutzelement und/oder die Steckerwandung separat gefertigt werden und anschliessend auf einer elektrisch isolierenden Schutzelementbasis, welche sich zumindest teilweise oder vollständig um den Kontaktstift herum erstreckt, angeordnet werden.However, it is also conceivable that the protective element is manufactured separately from the connector housing and, following manufacture, is for example passed through a corresponding recess in the connector base through the pin-side connector housing and fastened therein. It is also conceivable that the protective element and / or the plug wall are manufactured separately and then arranged on an electrically insulating protective element base which extends at least partially or completely around the contact pin.

Bevorzugterweise ist ein elektrisch isolierender Kontaktschutz, vorzugsweise in Form einer Schutzkappe, auf dem freien Ende des Kontaktstiftes angeordnet.An electrically insulating contact protection, preferably in the form of a protective cap, is preferably arranged on the free end of the contact pin.

Der buchsenseitige Stecker weist ein buchsenseitiges Steckergehäuse mit einer Steckerbasis und einer Steckerwandung, und eine Buchse, welche im buchsenseitigen Steckergehäuse angeordnet ist und zur Aufnahme des Kontaktstiftes im verbundenen Zustand ausgebildet ist, auf. Das buchsenseitige Steckergehäuse weist eine Aufnahme zur Aufnahme des Schutzelementes im verbundenen Zustand auf.The socket-side plug has a socket-side plug housing with a plug base and a plug wall, and a socket which is arranged in the socket-side plug housing and is designed to receive the contact pin in the connected state. The socket-side connector housing has a receptacle for receiving the protective element in the connected state.

Werden der stiftseitige Stecker und der buchsenseitige Stecker miteinander verbunden, so wird das Schutzelement in der Aufnahme des buchsenseitigen Steckers aufgenommen und es wird eine Steckverbindersystem mit einer kompakten Konstruktion zur Verfügung gestellt.If the pin-side connector and the socket-side connector are connected to one another, the protective element is received in the receptacle of the socket-side connector and a connector system with a compact design is made available.

Auch hier gilt zu verstehen, dass der buchsenseitige Stecker je nach Anzahl Kontaktstifte beziehungsweise Schutzanordnungen des stiftseitigen Steckers über eine oder mehrere Buchsen und Aufnahmen verfügen kann.Here, too, it should be understood that the socket-side plug can have one or more sockets and receptacles, depending on the number of contact pins or protective arrangements of the pin-side plug.

Vorzugsweise umrahmt die Aufnahme das Schutzelement im verbundenen Zustand zumindest teilweise, wobei das Schutzelement vorzugsweise passgenau in der Aufnahme aufnehmbar ist und/oder wobei die Aufnahme vorzugsweise zur Aufnahme der im Wesentlichen gesamten Länge des Schutzelementes ausgebildet ist.The receptacle preferably frames the protective element at least partially in the connected state, the protective element preferably being able to be received in the receptacle with a precise fit and / or the receptacle preferably being designed to accommodate the substantially entire length of the protective element.

Die Aufnahme weist bevorzugterweise eine im Wesentlichen rechteckige Form auf, deren Innenflächen im verbundenen Zustand zu den Aussenflächen des Schutzelementes Spiel aufweisen. Vorzugsweise umgibt die Aufnahme das Schutzelement im Bereich der Aufnahme im Wesentlichen vollständig.The receptacle preferably has an essentially rectangular shape, the inner surfaces of which have play in the connected state with the outer surfaces of the protective element. The receptacle preferably surrounds the protective element essentially completely in the region of the receptacle.

Beispielsweise kann zur passgenauen Aufnahme eines wie oben beschriebenen U-förmigen Schutzelements die dem Schutzelement zugewandte Innenform der Aufnahme derart ausgebildet sein, dass sie über eine entsprechend zum gebogenen Basisschenkel des Schutzelementes gebogene Innenfläche verfügt, sowie über jeweils zwei entsprechend zu den geraden Seitenschenkel des Schutzelements gerade, parallel zueinander ausgerichtete Innenflächen verfügt.For example, for a precisely fitting reception of a U-shaped protective element as described above, the inner shape of the receptacle facing the protective element can be designed in such a way that it has an inner surface that is curved corresponding to the curved base leg of the protective element, as well as two in each case corresponding to the straight side legs of the protective element , has inner surfaces aligned parallel to one another.

Das buchsenseitige Steckergehäuse weist vorzugsweises eine weitere, insbesondere kreisförmige, Ausnehmung auf, in welche die insbesondere kreissegmentförmige Steckerwandung aufnehmbar ist. Im Falle von einem oder mehreren Kontaktstiften weist das buchsenseitige Steckergehäuse vorzugsweise ebenfalls eine oder mehrere Ausnehmungen auf.The socket-side plug housing preferably has a further, in particular circular, recess in which the plug wall, in particular in the form of a segment of a circle, can be received. In the case of one or more contact pins, the socket-side connector housing preferably also has one or more recesses.

Bevorzugterweise ist ein Kontaktelement, insbesondere eine Kontaktlamelle, in der Buchse angeordnet, welches zur elektrischen Kontaktierung mit dem Kontaktstift des stiftseitigen Steckers ausgebildet ist.A contact element, in particular a contact lamella, is preferably arranged in the socket, which contact element is designed for electrical contact with the contact pin of the pin-side plug.

Im verbundenen Zustand erfolgt also eine elektrische Kontaktierung zwischen dem Kontaktstift und der Buchse über das besagte Kontaktelement.In the connected state, electrical contact is made between the contact pin and the socket via said contact element.

Gemäss der Erfindung ist die Buchse in einem Leiterelement angeordnet. Die besagte Aufnahme für das Schutzelement erstreckt sich in das Leiterelement hinein. Mit anderen Worten gesagt weist das Leiterelement eine Ausnehmung auf, in welche sich die Aufnahme des Schutzelementes hinein erstreckt. Folglich ragt das Schutzelement also durch die Aufnahme des Steckerelementes und durch die Ausnehmung im Leiterelement hindurch. Der Strompfad im Leiterelement verläuft dabei seitlich zur Ausnehmung.According to the invention, the socket is arranged in a conductor element. Said receptacle for the protective element extends into the conductor element. In other words, the conductor element has a recess into which the receptacle of the protective element extends. Consequently, the protective element protrudes through the receptacle of the plug element and through the recess in the conductor element. The current path in the conductor element runs laterally to the recess.

Vorzugsweise liegt die besagte Ausnehmung unterhalb der Buchse.Said recess is preferably located below the socket.

Gemäss der Erfindung ist die Aufnahme im Leiterelement derart angeordnet, dass das Schutzelement ausschliesslich auf seiner Umfangsseite nicht aber auf seiner Stirnseite durch das Leiterelement umgeben ist. Die Umfangsseite ist dabei die Seite des Schutzelementes, welche durch Teile der sich um die Mittelachse herumerstreckende Mantelfläche gebildet wird. Die Stirnseite ist die Seite des Schutzelementes, welche rechtwinklig zur Mittelachse orientiert ist und das Schutzelement nach vorne hin abschliesst.According to the invention, the receptacle in the conductor element is arranged in such a way that the protective element is surrounded by the conductor element only on its peripheral side but not on its end face. The peripheral side is the side of the protective element which is formed by parts of the lateral surface extending around the central axis. The front side is the side of the protective element which is oriented at right angles to the central axis and closes the protective element towards the front.

Aufgrund der Tatsache, dass sich die Aufnahme in das Leiterelement hinein erstreckt, ergeht der Vorteil, dass die Buchsenseite kompakter ausgebildet werden kann.Due to the fact that the receptacle extends into the conductor element, there is the advantage that the socket side can be made more compact.

Die Aufnahme wird in der besonders bevorzugten Ausführungsform sowohl durch das buchsenseitige Steckergehäuse als auch durch das Leiterelement bereitgestellt.In the particularly preferred embodiment, the receptacle is provided both by the socket-side connector housing and by the conductor element.

Vorzugsweise weist das Leiterelement einen Anschlussbereich für ein Kabel auf und ist insbesondere winklig oder parallel zur Steckerbasis des buchsenseitigen Steckergehäuses ausgebildet ist. Beispielsweise kann der Anschlussbereich senkrecht zur Steckerbasis angeordnet sein. Bei der rechtwinkligen Ausführung ist die Anordnung der Ausnehmung im Leiterelement besonders vorteilhaft, weil dann das Schutzelement in Steckrichtung in die Ausnehmung einragen kann.The conductor element preferably has a connection area for a cable and is in particular formed at an angle or parallel to the plug base of the socket-side plug housing. For example, the connection area can be arranged perpendicular to the connector base. In the case of the right-angled design, the arrangement of the recess in the conductor element is particularly advantageous because the protective element can then protrude into the recess in the insertion direction.

Analog kann auch der stiftseitige Stecker über einen Anschlussbereich für ein Kabel verfügen, welcher ebenfalls winklig, insbesondere senkrecht, oder parallel zum stiftseitigen Steckergehäuse ausgebildet sein kann.Similarly, the pin-side plug can also have a connection area for a cable, which is also angled, in particular perpendicular, or parallel to the pin-side Connector housing can be formed.

Weitere Ausführungsformen sind in den abhängigen Ansprüchen angegeben.Further embodiments are given in the dependent claims.

BESCHREIBUNG BEVORZUGTER AUSFÜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

Die Figuren 1 bis 4 zeigen unterschiedliche Ansichten eines stiftseitigen Steckers S und eines buchsenseitigen Steckers B jeweils einzeln (Figuren 1 und 2), im unverbundenen (Figur 3) sowie im verbundenen Zustand (Figur 4).The Figures 1 to 4 show different views of a pin-side connector S and a socket-side connector B, each individually ( Figures 1 and 2 ), in the unconnected ( Figure 3 ) as well as in the connected state ( Figure 4 ).

Wie insbesondere aus Figur 1 hervorgeht, weist der stiftseitige Stecker S ein stiftseitiges Steckergehäuse 6 mit einer Steckerbasis 61 und einer Steckerwandung 62, 62' auf. Das Steckergehäuse 6 ist hier auf einer stiftseitigen Fassung 2 angeordnet, welche wiederum über eine Gehäusefassung 21 sowie eine Gehäusebasis 22 verfügt. Auf der Steckerbasis 61 sind zwei elektrisch leitende Kontaktstifte 3, 3' angeordnet, welche jeweils über ein freies Stiftende 31, 31 und ein basisseitiges Stiftende 32, 32' verfügen. Die Kontaktstifte 3, 3' sind mit ihrem basisseitigen Stiftende 32, 32' am stiftseitigen Steckergehäuse 6 befestigt.Like in particular from Figure 1 As can be seen, the pin-side connector S has a pin-side connector housing 6 with a connector base 61 and a connector wall 62, 62 '. The connector housing 6 is arranged here on a socket 2 on the pin side, which in turn has a housing socket 21 and a housing base 22. Two electrically conductive contact pins 3, 3 'are arranged on the plug base 61, each of which has a free pin end 31, 31 and a pin end 32, 32' on the base. The contact pins 3, 3 'are fastened with their base-side pin end 32, 32' to the pin-side connector housing 6.

Weiter sind zwei elektrisch isolierende Schutzelemente 5, 5' vorgesehen, welche jeweils beabstandet von den Kontaktstiften 3, 3' am stiftseitigen Steckergehäuse 6 angeordnet sind. Das stiftseitige Steckergehäuse 6 weist hier eine kreissegmentförmig ausgebildete Steckerwandung 62, 62' auf, wobei jeweils eine kreissegmentförmige Wandung 62, 62' einen Kontaktstift 3, 3' entlang einer Umfangsrichtung um den jeweiligen Kontaktstift 3, 3' herum zumindest teilweise umgibt.Furthermore, two electrically insulating protective elements 5, 5 ′ are provided, which are each arranged at a distance from the contact pins 3, 3 ′ on the plug housing 6 on the pin side. The pin-side connector housing 6 here has a circular segment-shaped connector wall 62, 62 ', with a circular segment-shaped wall 62, 62' at least partially surrounding a contact pin 3, 3 'along a circumferential direction around the respective contact pin 3, 3'.

Obwohl in den hier gezeigten Figuren jeweils zwei Kontaktstifte 3, 3' mit entsprechenden Schutzelementen 5, 5' sowie Steckerwandungen 62, 62' dargestellt sind, kann nur ein solcher Kontaktstift mit einem Schutzelement und einer Steckerwandung oder drei und mehr solche Kontaktstifte mit jeweils drei oder mehr Schutzelementen und drei oder mehr Steckerwandungen vorgesehen sein.Although the figures shown here show two contact pins 3, 3 'with corresponding protective elements 5, 5' and plug walls 62, 62 ', only one such contact pin with a protective element and one plug wall or three or more such contact pins with three or more more protective elements and three or more plug walls can be provided.

Die Steckerwandungen 62, 62' und das Schutzelement 5, 5' sind derart angeordnet, dass verhindert wird, dass ein Prüffinger oder aber auch ein menschlicher Finger den Kontaktstift 3, 3' berühren kann.The plug walls 62, 62 'and the protective element 5, 5' are arranged in such a way that it is prevented that a test finger or a human finger can touch the contact pin 3, 3 '.

Das Schutzelement 5, 5' ist dabei jeweils separat vom Kontaktstift 3, 3' ausgebildet und derart vom Kontaktstift 3, 3' beabstandet angeordnet, dass es die Mantelfläche 33, 33' des zylinderförmigen Kontaktstiftes 3, 3' nicht berührt. Die Steckerwandung 62, 62' des stiftseitigen Steckergehäuses 6 ist ebenfalls elektrisch isolierend ausgebildet sowie beabstandet von den Kontaktstiften 3, 3' sowie von den Schutzelementen 5, 5' am stiftseitigen Steckergehäuse 6 angeordnet. Die Steckerwandung 62, 62' kann somit als ein weiteres elektrisch isolierendes Schutzelement zur Verhinderung einer ungewollten Berührung des Kontaktstiftes 3, 3' verstanden werden.The protective element 5, 5 'is formed separately from the contact pin 3, 3' and is arranged at a distance from the contact pin 3, 3 'in such a way that it does not touch the lateral surface 33, 33' of the cylindrical contact pin 3, 3 '. The plug wall 62, 62 'of the plug housing 6 on the pin side is also designed to be electrically insulating and spaced apart from the contact pins 3, 3' and from the protective elements 5, 5 'on the plug housing 6 on the pin side. The plug wall 62, 62 'can thus be understood as a further electrically insulating protective element for preventing unintentional contact with the contact pin 3, 3'.

Die Schutzelemente 5, 5' und die Steckerwandungen 62, 62' sind dabei jeweils quasi konzentrisch um den entsprechenden Kontaktstift 3, 3' herum angeordnet und erstrecken sich ausgehend von der stiftseitigen Steckerbasis 61 in Richtung des freien Endes 31, 31' des Kontaktstiftes 3, 3' im Wesentlichen entlang einer gesamten Länge LK des Kontaktstiftes 3, 3'.The protective elements 5, 5 'and the plug walls 62, 62' are each arranged quasi concentrically around the corresponding contact pin 3, 3 'and extend from the pin-side plug base 61 in the direction of the free end 31, 31' of the contact pin 3, 3 'essentially along an entire length LK of the contact pin 3, 3'.

Wie bereits erwähnt erstreckt sich die Steckerwandung 62, 62' nur teilweise um den Kontaktstift 3, 3' herum und verfügt über einen Unterbruch 63, 63', wobei das Schutzelement 5, 5' im Bereich dieses Unterbruchs 63, 63' auf dem stiftseitigen Steckergehäuse 6 angeordnet ist. In den hier gezeigten Ausführungsformen ist die Steckerwandung 62, 62' umfangsseitig genau einmal unterbrochen, wobei allerdings auch mehrere solche Unterbrechungen denkbar sind. Das Schutzelement 5, 5' ist jeweils im selben radialen Abstand zum Kontaktstift 3, 3' angeordnet wie die Steckerwandung 62, 62' zum Kontaktstift 3, 3' angeordnet ist.As already mentioned, the plug wall 62, 62 'extends only partially around the Contact pin 3, 3 'around and has an interruption 63, 63', the protective element 5, 5 'being arranged in the area of this interruption 63, 63' on the plug housing 6 on the pin side. In the embodiments shown here, the plug wall 62, 62 'is interrupted exactly once on the circumference, although several such interruptions are also conceivable. The protective element 5, 5 'is in each case arranged at the same radial distance from the contact pin 3, 3' as the plug wall 62, 62 'is arranged from the contact pin 3, 3'.

Das Schutzelement 5, 5' ist hier im Wesentlichen U-förmig ausgebildet und weist einen ersten Abschnitt 51, 51' in Form eines Basisschenkels auf, welcher sich entlang einer ersten Richtung R1 erstreckt. Weiter weist das Schutzelement 51, 51' einen zweiten Abschnitt 52, 52' 53, 53' in Form von einander gegenüberliegenden Seitenschenkeln auf, welche vom Basisschenkel 51, 51' vorstehen und sich entlang einer zweiten Richtung R2 erstrecken. Im Falle eines U-förmigen Schutzelements 5, 5' erstreckt sich die zweite Richtung R2 im Wesentlichen senkrecht zur ersten Richtung R1. In anderen Worten sind die Seitenschenkel 52, 52' 53, 53' im Wesentlichen senkrecht zum Basisschenkel 51, 51' angeordnet und dabei dem Kontaktstift 3, 3' zugewandt. Die Seitenschenkel 52, 52' 53, 53' dienen einer Verstärkung des Basisschenkels 51, 51' gegenüber einer Verformung des Basisschenkels 51, 51'. Der Basisschenkel 51, 51' verfügt hier über eine Breite BS, welche im Wesentlichen einer Breite BK des Kontaktstiftes 3, 3' entspricht.The protective element 5, 5 'is essentially U-shaped here and has a first section 51, 51' in the form of a base leg which extends along a first direction R1. Furthermore, the protective element 51, 51 'has a second section 52, 52' 53, 53 'in the form of mutually opposite side legs which protrude from the base leg 51, 51' and extend along a second direction R2. In the case of a U-shaped protective element 5, 5 ', the second direction R2 extends essentially perpendicular to the first direction R1. In other words, the side limbs 52, 52 '53, 53' are arranged essentially perpendicular to the base limb 51, 51 'and face the contact pin 3, 3'. The side legs 52, 52 '53, 53' serve to reinforce the base leg 51, 51 'against deformation of the base leg 51, 51'. The base leg 51, 51 'here has a width BS which essentially corresponds to a width BK of the contact pin 3, 3'.

Die Länge des Schutzelementes 5, 5' in Richtung der Mittelachse M gesehen ist vorzugsweise grösser als die Länge des Kontaktstiftes. Der Kontaktstift erstreckt sich im Wesentlichen in Richtung der Mittelachse bzw. der Mantelfläche des Kontaktstiftes.The length of the protective element 5, 5 'viewed in the direction of the central axis M is preferably greater than the length of the contact pin. The contact pin extends essentially in the direction of the central axis or the lateral surface of the contact pin.

Die Aussenform 54, 54' des U-förmigen Schutzelementes 5, 5' ist dabei derart ausgebildet, dass der Basisschenkel 51, 51' über eine gebogene Aussenfläche 54, 54' verfügt, während die Seitenschenkel 52, 52' 53, 53' jeweils mit geraden, parallel zueinander ausgerichteten Aussenflächen 54, 54' versehen sind. Die dem Kontaktstift 3 zugewandte Innenform 55, 55' des U-förmigen Schutzelements 5, 5' ist hingegen derart, dass sowohl der Basisschenkel 51, 51' wie auch die Seitenschenkel 52, 52' 53, 53' jeweils über gerade Innenflächen 55, 55' verfügen, wobei die Innenflächen 55, 55' der Seitenschenkel 52, 52' 53, 53' im Wesentlichen senkrecht auf die Innenfläche 55, 55' des Basisschenkels 51, 51' stehen. Wie insbesondere aus Figur 1 hervorgeht, verfügen die Seitenschenkel 52, 52' 53, 53' an ihren dem Kontaktstift 3, 3' zugewandten freien Enden 57, 57' jeweils über eine schräge Endfläche, welche jeweils ausgehend von der Aussenfläche 54, 54' des Seitenschenkels 52, 52' 53, 53' in Richtung der Innenfläche 55, 55' des Seitenschenkels 52, 52' 53, 53' geneigt ausgebildet sind.The outer shape 54, 54 'of the U-shaped protective element 5, 5' is designed such that the base leg 51, 51 'has a curved outer surface 54, 54', while the side legs 52, 52 '53, 53' each with straight, parallel outer surfaces 54, 54 'are provided. The inner shape 55, 55 'of the U-shaped protective element 5, 5' facing the contact pin 3, however, is such that both the base leg 51, 51 'and the side legs 52, 52' 53, 53 'each have straight inner surfaces 55, 55 ', the inner surfaces 55, 55' of the side legs 52, 52 '53, 53' being essentially perpendicular to the inner surface 55, 55 'of the base leg 51, 51' stand. Like in particular from Figure 1 As can be seen, the side legs 52, 52 '53, 53' at their free ends 57, 57 'facing the contact pin 3, 3' each have an inclined end surface which, starting from the outer surface 54, 54 'of the side leg 52, 52' 53, 53 'are inclined in the direction of the inner surface 55, 55' of the side leg 52, 52 '53, 53'.

Die Steckerwandung 62, 62' des stiftseitigen Steckergehäuses 6 weist auf ihrer dem Kontaktstift 3, 3' zugewandten Innenfläche 64, 64' zwei parallele Wandflächen 65, 65' auf, welche bezüglich einer sich ausgehend vom basisseitigen Stiftende 32, 32' in Richtung des freien Stiftendes 31, 31' entlang des Kontaktstifts 3, 3' erstreckenden Mittelachse M einander gegenüberliegend angeordnet und jeweils in einem gleichen Abstand von der Mittelachse M angeordnet sind. Zudem verfügt die Steckerwandung 62, 62' über einen bogenförmigen Abschnitt 66, 66', welcher die zwei parallelen Wandflächen 65, 65' bogenförmig miteinander verbindet. Die Wandflächen 65, 65' können innenseitig und aussenseitig angeordnet werden. Das Schutzelement 5, 5' ist bezüglich der Steckerwandung 62, 62' in einer Ebene E angeordnet, welche durch die Mittelachse M und durch einen Bogenmittelpunkt B des bogenförmigen Abschnitts 66, 66' der Steckerwandung 62, 62' festgelegt ist. Das Schutzelement 5, 5' ist dabei in dieser Ebene E mittig zwischen den parallelen Wandflächen 65, 65' angeordnet. In anderen Worten ist die Steckerwandung 62, 62' mit ihrem bogenförmigen Abschnitt 66, 66' sowie mit dem die parallelen Wandflächen 65, 65' aufweisenden Abschnitt im Wesentlichen kreissegmentförmig ausgebildet, wobei das Schutzelement 5, 5' in einem Unterbruch 63, 63' sowie insbesondere auf einer Kreislinie dieser kreissegmentförmigen Steckerwandung 62, 62' angeordnet ist. Der bogenförmige Abschnitt 66, 66' erstreckt sich um eine parallel zur Mittelachse liegenden Achse.The connector wall 62, 62 'of the pin-side connector housing 6 has on its inner surface 64, 64' facing the contact pin 3, 3 'two parallel wall surfaces 65, 65' which, starting from the base-side pin end 32, 32 'in the direction of the free Pin end 31, 31 'along the contact pin 3, 3' extending central axis M are arranged opposite one another and are each arranged at the same distance from the central axis M. In addition, the plug wall 62, 62 'has an arcuate section 66, 66' which connects the two parallel wall surfaces 65, 65 'to one another in an arcuate manner. The wall surfaces 65, 65 'can be arranged on the inside and outside. The protective element 5, 5 'is arranged with respect to the plug wall 62, 62' in a plane E which is defined by the central axis M and by an arc center point B of the arcuate section 66, 66 'of the plug wall 62, 62'. The protective element 5, 5 'is arranged in this plane E centrally between the parallel wall surfaces 65, 65'. In other words, the plug wall 62, 62 'with its arcuate section 66, 66' and with the section having the parallel wall surfaces 65, 65 'is essentially in the shape of a segment of a circle, the protective element 5, 5' in an interruption 63, 63 'and is arranged in particular on a circular line of this circular segment-shaped plug wall 62, 62 '. The arcuate section 66, 66 'extends around an axis lying parallel to the central axis.

Weiter weist die Steckerwandung 62, 62' aussenseitig, also auf ihrer der Gehäusefassung 21 zugewandten Aussenseite, im Bereich der parallelen Wandflächen 65, 65' jeweils eine Einrillung 67, 67' auf. Diese Einrillungen 67, 67' sind in Form von länglichen Schlitzen ausgebildet, welche sich ausgehend von der Steckerbasis 61 in Richtung des freien Stiftendes 31, 31' im Wesentlichen entlang der gesamten Länge der Steckerwandung 62, 62' erstrecken.Furthermore, the plug wall 62, 62 'has a groove 67, 67' on the outside, that is to say on its outside facing the housing socket 21, in the area of the parallel wall surfaces 65, 65 '. These grooves 67, 67 'are designed in the form of elongated slots which, starting from the plug base 61, extend in the direction of the free pin end 31, 31' essentially along the entire length of the plug wall 62, 62 '.

In der hier gezeigten Ausführungsform ist das Schutzelement 5, 5' sowie die Steckerwandung 62, 62' einstückig mit dem Steckergehäuse 6 ausgebildet und diese bilden gemeinsam eine Schutzanordnung 8, 8' für den Kontaktstift 3, 3'.In the embodiment shown here, the protective element 5, 5 'and the plug wall 62, 62' are formed in one piece with the plug housing 6 and these together form a protective arrangement 8, 8 'for the contact pin 3, 3'.

Wie bereits erwähnt, sind in den hier gezeigten Figuren jeweils zwei Kontaktstifte 3, 3' mit entsprechenden Schutzelementen 5, 5' sowie Steckerwandungen 62, 62' dargestellt, wobei auch nur ein solcher Kontaktstift mit Schutzelement und Steckerwandung oder mehrere solcher Kontaktstifte mit jeweiligen Schutzelementen und Steckerwandungen vorgesehen sein können. Entsprechend kann eine Schutzanordnung für einen Kontaktstift respektive zwei oder mehr Schutzanordnungen für zwei oder mehr Kontaktstifte vorgesehen sein. Anders gesagt ist pro Kontaktstift eine zugehörige Schutzanordnung vorgesehen.As already mentioned, the figures shown here each show two contact pins 3, 3 'with corresponding protective elements 5, 5' and plug walls 62, 62 ', with only one such contact pin with protective element and plug wall or several such contact pins with respective protective elements and Plug walls can be provided. Correspondingly, a protective arrangement for one contact pin or two or more protective arrangements for two or more contact pins can be provided. In other words, an associated protective arrangement is provided for each contact pin.

Am freien Ende 31, 31' des Kontaktstiftes 3, 3' ist jeweils eine elektrisch isolierende Schutzkappe 4, 4' vorgesehen, welche als zusätzlicher elektrisch isolierenden Kontaktschutz gegen eine ungewollte Berührung des Kontaktstiftes 3, 3' dient. Die Schutzkappe 4, 4' erstreckt sich vollständig um die Mittelachse M herum um bedeckt das gesamte freie Ende 31, 31' des Kontaktstiftes 3, 3'. Aufgrund der Schutzanordnung 8, 8', welche eine laterale Schutzwirkung für den Kontaktstift 3, 3' bereitstellt, und der Schutzkappe 4, 4', welche eine oberseitige Schutzwirkung für den Kontaktstift 3, 3' bereitstellt, ist eine Berührung des Kontaktstifts 3, 3' im Wesentlichen verunmöglicht.At the free end 31, 31 'of the contact pin 3, 3', an electrically insulating protective cap 4, 4 'is provided, which serves as an additional electrically insulating contact protection against unintentional contact with the contact pin 3, 3'. The protective cap 4, 4 'extends completely around the central axis M and covers the entire free end 31, 31' of the contact pin 3, 3 '. Due to the protective arrangement 8, 8 ', which provides a lateral protective effect for the contact pin 3, 3', and the protective cap 4, 4 ', which provides a protective effect on the top for the contact pin 3, 3', the contact pin 3, 3 is touched 'essentially impossible.

Figur 2 zeigt einen buchsenseitigen Stecker B zur elektrischen Verbindung mit einem stiftseitigen Stecker S wie oben beschrieben. Dieser buchsenseitige Stecker B weist ein buchsenseitiges Steckergehäuse 9 mit einer Steckerbasis 91 und einer Steckerwandung 92 auf. Das buchsenseitige Steckergehäuse 9 ist ebenfalls auf einer buchsenseitigen Fassung 400 angeordnet, welche wiederum über eine buchsenseitige Gehäusefassung 401 sowie über eine buchsenseitige Gehäusebasis 402 verfügt. Eine Buchse 100, 100' ist im buchsenseitigen Steckergehäuse 9 angeordnet, welche zur Aufnahme des Kontaktstiftes 3, 3' im verbundenen Zustand ausgebildet ist. Weiter ist buchsenseitig eine Aufnahme 93, 93' zur Aufnahme des Schutzelementes 5, 5' im verbundenen Zustand angeordnet. Die Aufnahme 93, 93' erstreckt sich im vorliegenden Fall sowohl durch das Steckergehäuse 9 als auch durch das Leiterelement 300. Figure 2 shows a socket-side connector B for electrical connection to a pin-side connector S as described above. This socket-side plug B has a socket-side plug housing 9 with a plug base 91 and a plug wall 92. The socket-side plug housing 9 is also arranged on a socket-side socket 400, which in turn has a socket-side housing socket 401 and a socket-side housing base 402. A socket 100, 100 'is arranged in the socket-side connector housing 9, which is designed to receive the contact pin 3, 3' in the connected state. Furthermore, a receptacle 93, 93 'for receiving the protective element 5, 5' in the connected state is arranged on the socket side. In the present case, the receptacle 93, 93 ′ extends both through the connector housing 9 and through the conductor element 300.

Hier verfügt das buchsenseitige Steckergehäuse 9 über zwei solcher Aufnahmen 93, 93' für die zwei Kontaktstifte 3, 3' des stiftseitigen Steckers S. Verfügt der stiftseitige Stecker S über einen oder mehrere Kontaktstifte, so weist das buchsenseitige Steckergehäuse 9 einen oder mehrere Aufnahmen auf. In anderen Worten weist das buchsenseitige Steckergehäuse 9 also jeweils eine Aufnahme pro Kontaktstift auf.Here the socket-side connector housing 9 has two such receptacles 93, 93 'for the two contact pins 3, 3' of the pin-side connector S. If the pin-side connector S has one or more contact pins, the socket-side connector housing 9 has one or more receptacles. In other words, the socket-side connector housing 9 has one receptacle per contact pin.

Wie insbesondere aus der Figur 4 hervorgeht, wird das Schutzelement 5, 5' im verbundenen Zustand passgenau in der Aufnahme 93, 93' des buchsenseitigen Steckers B aufgenommen, wobei die Aufnahme 93, 93' das Schutzelement 5, 5' zumindest teilweise umrahmt. Die Aufnahme 93, 93' weist dazu eine im Wesentlichen rechteckige Form auf, deren Innenflächen 94, 94' im verbundenen Zustand die Aussenflächen 54, 54' des Schutzelementes 5, 5' wenigstens abschnittsweise umgibt.As in particular from the Figure 4 As can be seen, the protective element 5, 5 'in the connected state is received precisely in the receptacle 93, 93' of the socket-side plug B, the receptacle 93, 93 'at least partially framing the protective element 5, 5'. For this purpose, the receptacle 93, 93 'has an essentially rectangular shape, the inner surfaces 94, 94' of which, in the connected state, surrounds the outer surfaces 54, 54 'of the protective element 5, 5' at least in sections.

Zur passgenauen Aufnahme eines wie oben beschriebenen U-förmigen Schutzelements 5, 5' ist die dem Schutzelement 5, 5' zugewandte Innenform 94, 94' der Aufnahme 93, 93' derart ausgebildet, dass sie über eine entsprechend zum gebogenen Basisschenkel 51, 51' gebogene Innenfläche verfügt, sowie über jeweils zwei entsprechend zu den geraden Seitenschenkel 52, 52', 53, 53' gerade, parallel zueinander ausgerichtete Innenflächen verfügt.For a precisely fitting reception of a U-shaped protective element 5, 5 'as described above, the inner shape 94, 94' of the receptacle 93, 93 'facing the protective element 5, 5' is designed in such a way that it has a corresponding to the curved base leg 51, 51 ' has curved inner surface, as well as has two corresponding to the straight side legs 52, 52 ', 53, 53' straight, parallel to each other aligned inner surfaces.

Zusätzlich zur Aufnahme 93, 93' des Schutzelementes 5, 5' weist das buchsenseitige Steckergehäuse 9 eine weitere, insbesondere kreisförmige, Ausnehmung 95, 95' auf, in welche die insbesondere kreissegmentförmige Steckerwandung 62, 62' aufnehmbar ist. Diese Ausnehmung 95, 95' erstreckt sich hier vollständig um die Buchse 100, 100' sowie die Aufnahme 93, 93' herum. Auch hier gilt zu verstehen, dass jeweils eine Buchse und eine Ausnehmung pro Kontaktstift vorgesehen ist.In addition to the receptacle 93, 93 'of the protective element 5, 5', the socket-side connector housing 9 has a further, in particular circular, recess 95, 95 'in which the in particular circular segment-shaped connector wall 62, 62' can be received. This recess 95, 95 'extends here completely around the socket 100, 100' and the receptacle 93, 93 '. Here, too, it should be understood that a socket and a recess are provided for each contact pin.

Somit können der stiftseitige Stecker S und der buchsenseitige Stecker B zu einem Steckverbindersystem 1 zusammengefügt werden, wobei jeder Kontaktstift 3, 3' und jede zugehörige Schutzanordnung 8, 8' des stiftseitigen Steckers S in entsprechende Aufnahmen 93, 93' beziehungsweise Ausnehmungen 95, 95' des buchsenseitigen Steckers B, sowie die Gehäusefassung 21 der stiftseitigen Fassung 2 in der Gehäusefassung 401 der buchsenseitigen Fassung 400 aufgenommen werden, so dass eine nach aussen vollständig abgeschlossene Steckverbindung gebildet wird.Thus, the pin-side connector S and the socket-side connector B can be joined together to form a connector system 1, with each contact pin 3, 3 'and each associated protective arrangement 8, 8' of the pin-side connector S in corresponding receptacles 93, 93 'or recesses 95, 95'. of the socket-side plug B, as well as the housing socket 21 of the pin-side socket 2 are received in the housing socket 401 of the socket-side socket 400, so that one to the outside completely completed plug connection is formed.

Wie insbesondere aus den Figuren 4 und 5 hervorgeht ist ein Kontaktelement 200, hier in Form einer Kontaktlamelle, in der Buchse 100 angeordnet, welche zur elektrischen Kontaktierung mit dem Kontaktstift 3 des stiftseitigen Steckers S ausgebildet ist. Die Kontaktlamelle erstreckt sich dabei vorzugsweise vollständig entlang der gesamten Umfangsrichtung der Buchse 100. Die Buchse 100 wiederum ist in einem Leiterelement 300 angeordnet, welches einen Anschlussbereich 301 für ein Kabel aufweist und in der hier gezeigten Ausführungsform senkrecht zur Steckerbasis 91 des buchsenseitigen Steckergehäuses 9 ausgebildet ist. Anstelle eines senkrecht zur Steckerbasis 91 ausgebildeten Anschlussbereichs 301 kann auch ein parallel zur Steckerbasis 91 angeordneter Anschlussbereich vorgesehen sein.As in particular from the Figures 4 and 5 a contact element 200, here in the form of a contact lamella, is shown in the socket 100, which is designed for electrical contact with the contact pin 3 of the plug S on the pin side. The contact lamella preferably extends completely along the entire circumferential direction of the socket 100. The socket 100 in turn is arranged in a conductor element 300 which has a connection area 301 for a cable and, in the embodiment shown here, is perpendicular to the plug base 91 of the socket-side plug housing 9 . Instead of a connection area 301 formed perpendicular to the plug base 91, a connection area arranged parallel to the plug base 91 can also be provided.

Das Leiterelement 300 stellt, wie oben erläutert, einen Teil der Aufnahme 93, 93' bereit. Die Aufnahme durchdringt dabei das Leiterelement 300, wodurch sein Querschnitt geschwächt wird. Der Strompfad verläuft seitlich zur Aufnahme 93, 93'. Durch die Anordnung der Aufnahme 93, 93' im Leiterelement 300 ergeht der Vorteil, dass das Leiterelement 300 sehr einfach bereitgestellt werden kann. Mit anderen Worten gesagt, durchdringt das Schutzelement 5, 5' das Leiterelement, was den Vorteil hat, dass das Leiterelement 300 nicht um die Stirnseite des Schutzelement 5, 5' herum konstruiert werden muss. Das heisst, das Leiterelement 300 umgibt das Schutzelement 5, 5' um dessen Umfangsseite bzw. seitlich, nicht aber um die Stirnseite bzw. das proximale Ende des Schutzelementes herum. Hierdurch kann das Gehäuse kompakter gebaut werden.As explained above, the conductor element 300 provides part of the receptacle 93, 93 '. The receptacle penetrates the conductor element 300, whereby its cross section is weakened. The current path runs laterally to the receptacle 93, 93 '. The arrangement of the receptacle 93, 93 'in the conductor element 300 has the advantage that the conductor element 300 can be provided very easily. In other words, the protective element 5, 5 'penetrates the conductor element, which has the advantage that the conductor element 300 does not have to be constructed around the end face of the protective element 5, 5'. This means that the conductor element 300 surrounds the protective element 5, 5 'around its circumferential side or laterally, but not around the end face or the proximal end of the protective element. This allows the housing to be made more compact.

Obwohl in den Figuren nicht dargestellt, kann auch der stiftseitige Stecker S über einen Anschlussbereich für ein Kabel verfügen, welcher ebenfalls parallel oder winklig, insbesondere senkrecht, zum stiftseitigen Steckergehäuse 6 angeordnet sein kann.Although not shown in the figures, the pin-side connector S can also have a connection area for a cable, which can also be arranged parallel or at an angle, in particular perpendicular, to the pin-side connector housing 6.

Das oben beschriebene Steckergehäuse oder Buchsengehäuse oder auch andere Steckergehäuse und Buchsengehäuse werden typischerweise mit einem Spritzgiessverfahren hergestellt. Das buchsenseitige Steckergehäuse 9 umfasst eine Abschirmung 500. Die Abschirmung 500 wird an einem Aussenteil 501 und/oder einem Innenteil 502 angespritzt. Das besonders bevorzugte Verfahren ist wie folgt. Das Innenteil 501 der Abschirmung 500 wird zuerst an die Abschirmung 500 angespritzt. Danach wird das Aussenteil 502 der Abschirmung 500 angespritzt. Die Abschirmung 500 könnte auch an einem Aussenteil 502 angespritzt werden, wobei anschliessend das Innenteil 501 gespritzt wird.The plug housing or socket housing described above or also other plug housings and socket housings are typically produced using an injection molding process. The socket-side connector housing 9 comprises a shield 500. The shield 500 is injection molded onto an outer part 501 and / or an inner part 502. The most preferred method is as follows. The inner part 501 of the shield 500 is first molded onto the shield 500. The outer part 502 of the shield 500 is then injection molded on. The shielding 500 could also be injection-molded onto an outer part 502, the inner part 501 then being injection-molded.
