Definitions

  • the invention relates to an electrical connector, comprising a coding housing for electrical and mechanical connection with a compatible connector and a connector body for electrical and mechanical connection with an electrical assembly, according to claim 1.
  • the invention also relates to a method for assembling an electrical connector, which has a coding housing for electrical and mechanical connection to a compatible connector and a connector body for electrical and mechanical connection to an electrical assembly, according to claim 11.
  • the invention also relates to a connector system comprising an electrical connector, a compatible connector and an electrical assembly.
  • a connector of the generic type is from DE 20 2008 014 541 U1 known. Further connectors according to the preamble of claim 1 are from WO 01/04995 such as EP 0 887 892 A1 known.
  • Connectors are used to establish an electrical and mechanical connection with a correspondingly compatible or complementary further connector.
  • a connector can be a plug, a socket, a coupling or an adapter.
  • the term "plug connector" used in the context of the invention is representative of all variants.
  • plug-in connectors are fixed on printed circuit boards ("printed circuit boards", PCBs), as interfaces on device housings or on electrical cables, and enable access to electrical signals (data and / or electrical supply) of the corresponding electrical assembly.
  • the plug connectors generally have a plug body that is electrically and mechanically connected to the electrical assembly, for example a printed circuit board.
  • a coding housing which essentially serves to connect to a compatible connector, is usually attached to the plug body. The coding housing thus establishes the interface or the interface to the compatible connector and for this purpose is based on the compatible connector, for example in the arrangement and number of its electrical contact bodies or signal conductors / inner conductors and ground conductors / outer conductors, and with regard to its mechanical coding.
  • plug-in connectors should be designed to be mechanically robust or durable.
  • the plug connectors should withstand multiple insertion and removal or forces acting in or against the insertion direction, forces acting orthogonally to the insertion direction and torsional forces, undamaged.
  • a connector should provide good electrical properties, including a sufficiently high electromagnetic shielding and low contact resistance and ensure a vibration-proof contact, especially if the connector is to be suitable for high-frequency technology.
  • the coding housing is pushed onto the connector body in the insertion direction of the compatible connector and is then fixed.
  • the two components can be fixed, for example, by pressing.
  • the assembly methods in the insertion direction can be used particularly advantageously for automated processes, but they also have disadvantages.
  • the coding housing usually has latching means for the locking connection with the compatible plug connector, forces in particular in or against the insertion direction place a heavy load on the press connection between the coding housing and the plug body. Furthermore, the production of the individual components is complex since the tolerance chain of the electrical connection, which extends from the contact bodies of the coding housing via the coding housing to the plug body and finally to the electrical assembly, is relatively long. Ensuring the necessary component tolerances therefore makes production more difficult and can ultimately be a limiting factor for the maximum achievable data transmission speed of the connector.
  • the present invention is based on the object of providing an improved electrical connector which is particularly suitable for advantageously absorbing mechanical forces along or against the insertion direction, the connector being as insensitive as possible to manufacturing tolerances.
  • the present invention is also based on the object of providing a method for assembling an electrical connector, as a result of which, in particular, a mechanically robust electrical connector that is insensitive to tolerances can be provided.
  • the invention is also based on the object of providing a connector system comprising a connector which is improved with respect to the prior art,
  • the electrical connector comprises a coding housing for electrical and mechanical connection with a compatible connector and a connector body for electrical and mechanical Connection to an electrical assembly, the compatible plug connector being connectable to the coding housing along an insertion direction.
  • the coding housing is designed in such a way that the compatible plug connector can be electrically and mechanically connected to the coding housing in the insertion direction.
  • the coding housing can thus provide mechanical coding for the compatible plug connector or for a corresponding coding housing of the compatible plug connector.

  • the coding housing is preferably formed from a plastic or from an electrically non-conductive material.
  • the direction of insertion of the compatible plug connector usually runs along or at least parallel to the central axis or the longitudinal axis of the coding housing of the electrical plug connector.
  • the electrical assembly to which the plug body according to the invention can be connected can be, for example, an electrical cable, an adapter part, a device housing or preferably an electrical circuit board.
  • the invention is not to be understood as being restricted to use with a specific electrical assembly.
  • the invention is described below essentially with reference to a printed circuit board or printed circuit board connector, the connector body of which is electrically and mechanically with it is connected to an electrical assembly designed as a circuit board. Of course, this is not to be understood as restrictive.
  • the coding housing and the plug body have a mechanical connecting device. It is provided that the connecting device is designed to connect the coding housing and the plug body with one another in a form-fitting manner in the insertion direction, the connecting device providing a mounting movement that deviates from the insertion direction in order to connect the coding housing and the plug body to one another.
  • the coding housing is therefore not mounted on the plug body along the insertion direction. In this way, a form fit can advantageously be provided in the insertion direction.
  • the coding housing can be applied to the plug body along an assembly path that deviates from a path that the compatible connector must follow when it is inserted into the coding housing.
  • the connecting device of the coding housing and the plug body provides a form fit at least in the insertion direction
  • the coding housing can then no longer be moved along one degree of freedom in the insertion direction relative to the plug body; the coding housing and the plug body are positively or firmly connected to one another in the insertion direction. Possible tolerances or play in the connection device can be neglected or do not have a disruptive effect on the form-fitting connection. It is a particular advantage of the invention that for the positive connection of the coding housing to the plug body (in Insertion direction) no additional locking means or the like are required,
  • the connecting device enables tensile forces that arise in particular when pulling on the compatible connector plugged into the coding housing, as well as sometimes even transverse force components in relation to the insertion direction, to the plug body, which in turn is firmly connected to the electrical assembly.
  • a critical tensile force can advantageously be absorbed via the electrical assembly.
  • the solution according to the invention prevents the connection between the coding housing and the plug body from being damaged or loosened when tensile forces occur.
  • connection between the coding housing and the plug body is extremely robust in or against the insertion direction, in particular compared to a merely force-fit connection of the prior art.
  • recesses for at least one contact body are provided in the coding housing and in the plug body in order to introduce the at least one contact body in the plug-in direction through the coding housing into the plug body, the contact body and the recesses being designed in such a way that when the contact body is introduced the Coding housing and the plug body are fixed in their position, the at least one contact body can be arranged or preferably clamped in the recesses of the coding housing or the plug body in such a way that the coding housing can no longer be moved on the plug body or can no longer be dismantled from it.

  • the coding housing and the plug body are therefore preferably connected to one another in a form-fitting manner in all spatial directions.
  • the introduction of the at least one contact body can also result in an optimal alignment of the contact body with respect to the plug body. Since the at least one contact body is electrically and mechanically connected directly to the plug body by passing through the recess in the coding housing, the tolerance chain for the plug connector can be significantly improved. Finally, it is possible to ensure tight tolerances in the interface or in the connector according to the invention without taking special measures in the manufacture of the connector. The production of the electrical connector can thus be particularly economical.
  • a contact end stop can be provided in the plug body for the at least one contact body.

Description

Die Erfindung betrifft einen elektrischen Steckverbinder, umfassend ein Kodiergehäuse zur elektrischen und mechanischen Verbindung mit einem kompatiblen Steckverbinder und einen Steckerkörper zur elektrischen und mechanischen Verbindung mit einer elektrischen Baugruppe, gemäß Anspruch 1.The invention relates to an electrical connector, comprising a coding housing for electrical and mechanical connection with a compatible connector and a connector body for electrical and mechanical connection with an electrical assembly, according to claim 1.

Die Erfindung betrifft auch ein Verfahren zur Montage eines elektrischen Steckverbinders, der ein Kodiergehäuse zur elektrischen und mechanischen Verbindung mit einem kompatiblen Steckverbinder und einen Steckerkörper zur elektrischen und mechanischen Verbindung mit einer elektrischen Baugruppe aufweist, gemäß Anspruch 11.The invention also relates to a method for assembling an electrical connector, which has a coding housing for electrical and mechanical connection to a compatible connector and a connector body for electrical and mechanical connection to an electrical assembly, according to claim 11.

Die Erfindung betrifft außerdem ein Steckverbindersystem, umfassend einen elektrischen Steckverbinder, einen kompatiblen Steckverbinder und eine elektrische Baugruppe.The invention also relates to a connector system comprising an electrical connector, a compatible connector and an electrical assembly.

Ein gattungsgemäßer Steckverbinder ist aus der DE 20 2008 014 541 U1 bekannt. Weitere Steckverbinder gemäß Oberbegriff des Anspruchs 1 sind aus WO 01/04995 sowie EP 0 887 892 A1 bekannt.A connector of the generic type is from DE 20 2008 014 541 U1 known. Further connectors according to the preamble of claim 1 are from WO 01/04995 such as EP 0 887 892 A1 known.

Steckverbinder dienen dazu, eine elektrische und mechanische Verbindung mit einem entsprechend kompatiblen bzw. komplementären weiteren Steckverbinder herzustellen. Bei einem Steckverbinder kann es sich um einen Stecker, eine Buchse, eine Kupplung oder einen Adapter handeln. Die im Rahmen der Erfindung verwendete Bezeichnung "Steckverbinder" steht stellvertretend für alle Varianten.Connectors are used to establish an electrical and mechanical connection with a correspondingly compatible or complementary further connector. A connector can be a plug, a socket, a coupling or an adapter. The term "plug connector" used in the context of the invention is representative of all variants.

Meist werden Steckverbinder auf Leiterplatten ("Printed Circuit Boards", PCBs), als Schnittstellen an Gerätegehäusen oder an elektrischen Kabeln festgelegt und ermöglichen einen Zugang zu elektrischen Signalen (Daten und/oder elektrische Versorgung) der entsprechenden elektrischen Baugruppe. Hierzu weisen die Steckverbinder in der Regel einen Steckerkörper auf, der elektrisch und mechanisch mit der elektrischen Baugruppe, beispielsweise einer Leiterplatte, verbunden ist. An den Steckerkörper schließt sich in der Regel ein Kodiergehäuse an, das im Wesentlichen zur Verbindung mit einem kompatiblen Steckverbinder dient. Das Kodiergehäuse stellt somit die Schnittstelle bzw. das Interface zu dem kompatiblen Steckverbinder her und ist hierzu beispielsweise in der Anordnung und Anzahl seiner elektrischen Kontaktkörper bzw. Signalleiter/Innenleiter und Masseleiter/Außenleiter sowie bezüglich seiner mechanischen Kodierung auf den kompatiblen Steckverbinder abgestellt.Most plug-in connectors are fixed on printed circuit boards ("printed circuit boards", PCBs), as interfaces on device housings or on electrical cables, and enable access to electrical signals (data and / or electrical supply) of the corresponding electrical assembly. For this purpose, the plug connectors generally have a plug body that is electrically and mechanically connected to the electrical assembly, for example a printed circuit board. A coding housing, which essentially serves to connect to a compatible connector, is usually attached to the plug body. The coding housing thus establishes the interface or the interface to the compatible connector and for this purpose is based on the compatible connector, for example in the arrangement and number of its electrical contact bodies or signal conductors / inner conductors and ground conductors / outer conductors, and with regard to its mechanical coding.

Grundsätzlich sollten Steckverbinder mechanisch robust bzw. langlebig ausgebildet sein. Insbesondere sollten die Steckverbinder dabei mehrfaches Ein- und Ausstecken bzw. in oder entgegen die Einsteckrichtung wirkenden Kräfte, orthogonal zur Einsteckrichtung wirkende Kräfte und Torsionskräfte, unbeschadet überstehen. Außerdem sollte ein Steckverbinder gute elektrische Eigenschaften bereitstellen, unter anderem eine ausreichend hohe elektromagnetische Abschirmung, geringe Kontaktwiderstände und eine vibrationssichere Kontaktierung gewährleisten, vor allem wenn sich der Steckverbinder für die Hochfrequenztechnik eignen soll.In principle, plug-in connectors should be designed to be mechanically robust or durable. In particular, the plug connectors should withstand multiple insertion and removal or forces acting in or against the insertion direction, forces acting orthogonally to the insertion direction and torsional forces, undamaged. In addition, a connector should provide good electrical properties, including a sufficiently high electromagnetic shielding and low contact resistance and ensure a vibration-proof contact, especially if the connector is to be suitable for high-frequency technology.

Bei den aus der Praxis bekannten Montageverfahren für elektrische Steckverbinder ist vorgesehen, dass das Kodiergehäuse in Einsteckrichtung des kompatiblen Steckverbinders auf den Steckerkörper aufgeschoben und anschließend fixiert wird. Die Fixierung der beiden Komponenten kann beispielsweise durch ein Verpressen erfolgen. Die Montageverfahren in Einsteckrichtung sind besonders vorteilhaft für automatisierte Prozesse verwendbar, zeigen jedoch auch Nachteile.In the assembly methods known from practice for electrical connectors, it is provided that the coding housing is pushed onto the connector body in the insertion direction of the compatible connector and is then fixed. The two components can be fixed, for example, by pressing. The assembly methods in the insertion direction can be used particularly advantageously for automated processes, but they also have disadvantages.

Da das Kodiergehäuse in der Regel Rastmittel zur rastenden Verbindung mit dem kompatiblen Steckverbinder aufweist, belasten insbesondere Kräfte in oder entgegen die Einsteckrichtung die Pressverbindung zwischen Kodiergehäuse und Steckerkörper stark. Ferner ist die Herstellung der einzelnen Komponenten aufwändig, da die Toleranzkette der elektrischen Verbindung, die sich von den Kontaktkörpern des Kodiergehäuses über das Kodiergehäuse zu dem Steckerkörper und schließlich zu der elektrischen Baugruppe erstreckt, relativ lang ist. Die Sicherstellung der notwendigen Bauteiltoleranzen erschwert demnach die Herstellung und kann schließlich ein limitierender Faktor für die maximal erreichbare Datenübertragungsgeschwindigkeit der Steckverbinder sein.Since the coding housing usually has latching means for the locking connection with the compatible plug connector, forces in particular in or against the insertion direction place a heavy load on the press connection between the coding housing and the plug body. Furthermore, the production of the individual components is complex since the tolerance chain of the electrical connection, which extends from the contact bodies of the coding housing via the coding housing to the plug body and finally to the electrical assembly, is relatively long. Ensuring the necessary component tolerances therefore makes production more difficult and can ultimately be a limiting factor for the maximum achievable data transmission speed of the connector.

Es ist auch bekannt, das Kodiergehäuse nach dem Aufschieben auf den Steckerkörper durch entsprechende Rastmittel zu fixieren, wie beispielsweise in der gattungsgemäßen DE 20 2008 014 541 U1 angegeben. Hierdurch können Zugkräfte, die die Verbindung zwischen Kodiergehäuse und Steckerkörper belasten, in der Regel gut über den Steckerkörper auf die elektrische Baugruppe abgeleitet werden. Gleichwohl ist die Einhaltung der notwendigen Toleranzen für einen derartigen Steckverbinder nach wie vor nicht einfach.It is also known to fix the coding housing after it has been pushed onto the plug body by means of corresponding latching means, such as in the generic one DE 20 2008 014 541 U1 specified. As a result, tensile forces that load the connection between the coding housing and the connector body can usually be passed through the connector body can be derived from the electrical assembly. Nevertheless, compliance with the necessary tolerances for such a connector is still not easy.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen verbesserten elektrischen Steckverbinder bereitzustellen, der insbesondere geeignet ist, mechanische Kräfte entlang oder entgegen der Einsteckrichtung vorteilhaft aufzunehmen, wobei der Steckverbinder möglichst unempfindlich gegenüber Herstellungstoleranzen ist.The present invention is based on the object of providing an improved electrical connector which is particularly suitable for advantageously absorbing mechanical forces along or against the insertion direction, the connector being as insensitive as possible to manufacturing tolerances.

Der vorliegenden Erfindung liegt auch die Aufgabe zugrunde, ein Verfahren zur Montage eines elektrischen Steckverbinders bereitzustellen, wodurch insbesondere ein mechanisch robuster und toleranzunempfindlicher elektrischer Steckverbinder bereitgestellt werden kann.The present invention is also based on the object of providing a method for assembling an electrical connector, as a result of which, in particular, a mechanically robust electrical connector that is insensitive to tolerances can be provided.

Die Aufgabe wird für den elektrischen Steckverbinder durch Anspruch 1 und für das Verfahren zu dessen Montage durch Anspruch 11 gelöst.The object is achieved for the electrical connector by claim 1 and for the method for its assembly by claim 11.

Schließlich liegt der Erfindung auch die Aufgabe zugrunde, ein Steckverbindersystem, umfassend einen bezüglich des Standes der Technik verbesserten Steckverbinder, bereitzustellen,Finally, the invention is also based on the object of providing a connector system comprising a connector which is improved with respect to the prior art,

Diese Aufgabe wird durch die Merkmale des Anspruchs 17 gelöst. Die abhängigen Ansprüche betreffen vorteilhafte Ausführungsformen und Varianten der Erfindung.This object is achieved by the features of claim 17. The dependent claims relate to advantageous embodiments and variants of the invention.

Der erfindungsgemäße elektrische Steckverbinder umfasst ein Kodiergehäuse zur elektrischen und mechanischen Verbindung mit einem kompatiblen Steckverbinder und einen Steckerkörper zur elektrischen und mechanischen Verbindung mit einer elektrischen Baugruppe, wobei der kompatible Steckverbinder entlang einer Einsteckrichtung mit dem Kodiergehäuse verbindbar ist.The electrical connector according to the invention comprises a coding housing for electrical and mechanical connection with a compatible connector and a connector body for electrical and mechanical Connection to an electrical assembly, the compatible plug connector being connectable to the coding housing along an insertion direction.

Das Kodiergehäuse ist derart ausgebildet, dass der kompatible Steckverbinder in Einsteckrichtung mit dem Kodiergehäuse elektrisch und mechanisch verbindbar ist.The coding housing is designed in such a way that the compatible plug connector can be electrically and mechanically connected to the coding housing in the insertion direction.

Somit kann das Kodiergehäuse eine mechanische Kodierung für den kompatiblen Steckverbinder bzw. für ein korrespondierendes Kodiergehäuse des kompatiblen Steckverbinders bereitstellen. Das erfindungsgemäße Kodiergehäuse stellt somit den steckerseitigen Teil des erfindungsgemäßen Steckverbinders dar.The coding housing can thus provide mechanical coding for the compatible plug connector or for a corresponding coding housing of the compatible plug connector. The coding housing according to the invention thus represents the plug-side part of the connector according to the invention.

Das Kodiergehäuse ist vorzugsweise aus einem Kunststoff bzw. aus einem elektrisch nicht leitenden Material gebildet.The coding housing is preferably formed from a plastic or from an electrically non-conductive material.

Üblicherweise verläuft die Einsteckrichtung des kompatiblen Steckverbinders entlang oder zumindest parallel zu der Mittelachse bzw. der Längsachse des Kodiergehäuses des elektrischen Steckverbinders.The direction of insertion of the compatible plug connector usually runs along or at least parallel to the central axis or the longitudinal axis of the coding housing of the electrical plug connector.

Bei der elektrischen Baugruppe, mit der der erfindungsgemäße Steckerkörper verbindbar ist, kann es sich beispielsweise um ein elektrisches Kabel, ein Adapterteil, ein Gerätegehäuse oder vorzugsweise um eine elektrische Leiterplatte handeln. Grundsätzlich ist die Erfindung nicht auf die Verwendung mit einer bestimmten elektrischen Baugruppe beschränkt zu verstehen. Zur Vereinfachung ist die Erfindung nachfolgend im Wesentlichen anhand eines Leiterplatten- bzw. Platinensteckverbinders beschrieben, dessen Steckerkörper elektrisch und mechanisch mit einer als Leiterplatte ausgebildeten elektrischen Baugruppe verbunden ist. Dies ist selbstverständlich nicht einschränkend zu verstehen.The electrical assembly to which the plug body according to the invention can be connected can be, for example, an electrical cable, an adapter part, a device housing or preferably an electrical circuit board. In principle, the invention is not to be understood as being restricted to use with a specific electrical assembly. For the sake of simplicity, the invention is described below essentially with reference to a printed circuit board or printed circuit board connector, the connector body of which is electrically and mechanically with it is connected to an electrical assembly designed as a circuit board. Of course, this is not to be understood as restrictive.

Erfindungsgemäß weisen das Kodiergehäuse und der Steckerkörper eine mechanische Verbindungseinrichtung auf. Dabei ist vorgesehen, dass die Verbindungseinrichtung ausgebildet ist, um das Kodiergehäuse und den Steckerkörper in Einsteckrichtung formschlüssig miteinander zu verbinden, wobei die Verbindungseinrichtung eine von der Einsteckrichtung abweichende Montagebewegung vorgibt, um das Kodiergehäuse und den Steckerkörper miteinander zu verbinden.
Das Kodiergehäuse wird somit nicht entlang der Einsteckrichtung auf den Steckerkörper montiert. Auf diese Weise kann vorteilhaft ein Formschluss in Einsteckrichtung bereitgestellt werden.According to the invention, the coding housing and the plug body have a mechanical connecting device. It is provided that the connecting device is designed to connect the coding housing and the plug body with one another in a form-fitting manner in the insertion direction, the connecting device providing a mounting movement that deviates from the insertion direction in order to connect the coding housing and the plug body to one another.
The coding housing is therefore not mounted on the plug body along the insertion direction. In this way, a form fit can advantageously be provided in the insertion direction.

Das Kodiergehäuse kann entlang eines Montagepfades auf den Steckerkörper aufgebracht werden, der von einem Pfad, dem der kompatible Steckverbinder beim Einstecken in das Kodiergehäuse folgen muss, abweicht.The coding housing can be applied to the plug body along an assembly path that deviates from a path that the compatible connector must follow when it is inserted into the coding housing.

Dadurch, dass die Verbindungseinrichtung des Kodiergehäuses und des Steckerkörpers einen Formschluss zumindest in Einsteckrichtung bereitstellt, kann das Kodiergehäuse anschließend nicht mehr entlang eines Freiheitsgrades in Einsteckrichtung relativ zu dem Steckerkörper bewegt werden; das Kodiergehäuse und der Steckerkörper sind in Einsteckrichtung formschlüssig bzw. fest miteinander verbunden. Mögliche Toleranzen bzw. ein Spiel der Verbindungseinrichtung können dabei vernachlässig werden bzw. wirken sich nicht störend auf die formschlüssige Verbindung aus. Es ist ein besonderer Vorteil der Erfindung, dass für die formschlüssige Verbindung des Kodiergehäuses mit dem Steckerkörper (in Einsteckrichtung) keine zusätzlichen Rastmittel oder Ähnliches erforderlich sind,Because the connecting device of the coding housing and the plug body provides a form fit at least in the insertion direction, the coding housing can then no longer be moved along one degree of freedom in the insertion direction relative to the plug body; the coding housing and the plug body are positively or firmly connected to one another in the insertion direction. Possible tolerances or play in the connection device can be neglected or do not have a disruptive effect on the form-fitting connection. It is a particular advantage of the invention that for the positive connection of the coding housing to the plug body (in Insertion direction) no additional locking means or the like are required,

Durch die erfindungsgemäße Verbindungseinrichtung können Zugkräfte, die sich insbesondere dann ergeben, wenn an dem in das Kodiergehäuse eingesteckten kompatiblen Steckverbinder gezogen wird, sowie teilweise sogar Querkraftkomponenten in Bezug auf die Einsteckrichtung auf den Steckerkörper übertragen werden, der seinerseits mit der elektrischen Baugruppe fest verbunden ist. Somit kann eine kritische Zugkraft vorteilhaft über die elektrische Baugruppe abgefangen werden. In besonders vorteilhafter Weise vermeidet die erfindungsgemäße Lösung, dass beim Auftreten von Zugkräften die Verbindung zwischen dem Kodiergehäuse und dem Steckerkörper beschädigt bzw. gelöst wird.The connecting device according to the invention enables tensile forces that arise in particular when pulling on the compatible connector plugged into the coding housing, as well as sometimes even transverse force components in relation to the insertion direction, to the plug body, which in turn is firmly connected to the electrical assembly. Thus, a critical tensile force can advantageously be absorbed via the electrical assembly. In a particularly advantageous manner, the solution according to the invention prevents the connection between the coding housing and the plug body from being damaged or loosened when tensile forces occur.

Die Verbindung zwischen Kodiergehäuse und Steckerkörper ist in oder entgegen der Einsteckrichtung außerordentlich robust, insbesondere verglichen mit einer lediglich kraftschlüssigen Verbindung des Standes der Technik.The connection between the coding housing and the plug body is extremely robust in or against the insertion direction, in particular compared to a merely force-fit connection of the prior art.

Dadurch, dass in dem Kodiergehäuse und in dem Steckerkörper Ausnehmungen für wenigstens einen Kontaktkörper vorgesehen sein, um den wenigstens einen Kontaktkörper in Einsteckrichtung durch das Kodiergehäuse in den Steckerkörper einzubringen, wobei der Kontaktkörper und die Ausnehmungen derart beschaffen sind, dass durch das Einbringen des Kontaktkörpers das Kodiergehäuse und der Steckerkörper in ihrer Position fixiert sind, kann der wenigstens eine Kontaktkörper in den Ausnehmungen des Kodiergehäuses bzw, des Steckerkörpers derart angeordnet bzw. vorzugsweise eingeklemmt sein, dass das Kodiergehäuse auf dem Steckerkörper nicht mehr bewegt bzw. nicht mehr von diesem demontiert werden kann.In that recesses for at least one contact body are provided in the coding housing and in the plug body in order to introduce the at least one contact body in the plug-in direction through the coding housing into the plug body, the contact body and the recesses being designed in such a way that when the contact body is introduced the Coding housing and the plug body are fixed in their position, the at least one contact body can be arranged or preferably clamped in the recesses of the coding housing or the plug body in such a way that the coding housing can no longer be moved on the plug body or can no longer be dismantled from it.

Bei dem Kontaktkörper kann es sich um einen beliebigen elektrischen Leiter handeln, der beispielsweise als Innenleiter bzw. Signalleiter oder insbesondere als Außenleiter bzw. Masseleiter des erfindungsgemäßen Steckverbinders verwendbar ist.The contact body can be any electrical conductor that can be used, for example, as an inner conductor or signal conductor or, in particular, as an outer conductor or ground conductor of the connector according to the invention.

Die Positionierung des Kodiergehäuses relativ zu dem Steckerkörper kann somit durch den wenigstens einen Kontaktkörper festgelegt werden.The positioning of the coding housing relative to the plug body can thus be determined by the at least one contact body.

Grundsätzlich muss der Kontaktkörper nicht unbedingt entlang der Einsteckrichtung eingebracht werden, sondern kann auch entlang eines Winkels eingebracht werden, der relativ zu der Montagebewegung 30° bis 150°, vorzugsweise 45° bis 135° und besonders bevorzugt 80° bis 100° beträgt. Ganz besonders bevorzugt beträgt der Winkel allerdings 90° und verläuft entlang der Einsteckrichtung.In principle, the contact body does not necessarily have to be introduced along the insertion direction, but can also be introduced along an angle which is 30 ° to 150 °, preferably 45 ° to 135 ° and particularly preferably 80 ° to 100 ° relative to the assembly movement. However, the angle is very particularly preferably 90 ° and runs along the insertion direction.

Der Kontaktkörper und die entsprechenden Ausnehmungen für den Kontaktkörper können eine beliebige Geometrie aufweisen, insbesondere kann der wenigstens eine Kontaktkörper einen runden, einen rechteckigen (insbesondere quadratischen) oder einen sonstigen Querschnitt aufweisen. Der Kontaktkörper kann in massiver oder hohler Bauweise, insbesondere rohrförmig, ausgebildet sein und kann ggf. auch als Kontakthülse bezeichnet werden.The contact body and the corresponding recesses for the contact body can have any geometry, in particular the at least one contact body can have a round, rectangular (in particular square) or other cross section. The contact body can have a solid or hollow design, in particular tubular, and can optionally also be referred to as a contact sleeve.

Dadurch, dass die Verbindungseinrichtung einen Formschluss in Einsteckrichtung bereitstellt und somit zumindest den Translationsfreiheitsgrad in Einsteckrichtung blockiert, können durch das Einbringen des wenigstens einen Kontaktkörpers in Einsteckrichtung nunmehr alle noch verbleibenden Freiheitsgrade blockiert werden. Das Kodiergehäuse und der Steckerkörper sind nach dem Einbringen des Kontaktkörpers somit vorzugsweise in alle Raumrichtungen formschlüssig miteinander verbunden.Because the connecting device provides a form fit in the insertion direction and thus blocks at least the degree of translational freedom in the insertion direction, the introduction of the at least a contact body in the plug-in direction now all remaining degrees of freedom are blocked. After the contact body has been introduced, the coding housing and the plug body are therefore preferably connected to one another in a form-fitting manner in all spatial directions.

Neben dem Fixieren der relativen Position zwischen Kodiergehäuse und dem Steckerkörper kann durch das Einbringen des wenigstens einen Kontaktkörpers außerdem eine optimale Ausrichtung des Kontaktkörpers zu dem Steckerkörper erfolgen. Da der wenigstens eine Kontaktkörper unmittelbar mit dem Steckerkörper elektrisch und mechanisch verbunden ist, Indem er durch die Ausnehmung in dem Kodiergehäuse hindurchtritt, kann die Toleranzkette für den Steckverbinder wesentlich verbessert sein. Schließlich ist es möglich, enge Toleranzen im Interface bzw. in dem erfindungsgemäßen Steckverbinder sicherzustellen, ohne besondere Maßnahmen bei der Herstellung des Steckverbinders zu treffen. Die Herstellung des elektrischen Steckverbinders kann somit besonders wirtschaftlich sein.In addition to fixing the relative position between the coding housing and the plug body, the introduction of the at least one contact body can also result in an optimal alignment of the contact body with respect to the plug body. Since the at least one contact body is electrically and mechanically connected directly to the plug body by passing through the recess in the coding housing, the tolerance chain for the plug connector can be significantly improved. Finally, it is possible to ensure tight tolerances in the interface or in the connector according to the invention without taking special measures in the manufacture of the connector. The production of the electrical connector can thus be particularly economical.

Für den wenigstens einen Kontaktkörper kann ein Kontaktendanschlag in dem Steckerkörper vorgesehen sein. Alternativ oder zusätzlich kann der wenigstens eine Kontaktkörper einen in Richtung des Steckerkörpers vorzugsweise stufig verringerten Querschnitt aufweisen, um selbst einen Anschlag für das Einschieben auszubilden, wenn die Ausnehmung(en) in dem Kontaktkörper einen größeren Durchmesser aufweist bzw. aufweisen, als die korrespondierende(n) Ausnehmung(en) in dem Steckerkörper.A contact end stop can be provided in the plug body for the at least one contact body. As an alternative or in addition, the at least one contact body can have a cross-section that is preferably reduced in steps in the direction of the plug body in order to even form a stop for insertion if the recess (s) in the contact body has or have a larger diameter than the corresponding (n ) Recess (s) in the plug body.

In einer Weiterbildung der Erfindung kann vorgesehen sein, dass die Verbindungseinrichtung ein Schienensystem umfasst, wobei das Kodiergehäuse und der Steckerkörper jeweils wenigstens eine miteinander korrespondierende Führungsschiene aufweisen, die gemeinsam das Schienensystem ausbilden,In a further development of the invention, it can be provided that the connecting device comprises a rail system, the coding housing and the plug body each having at least one corresponding guide rail which together form the rail system,

Anstelle eines Schienensystems kann auch eine beliebige Führung vorgesehen sein, die sicherstellt, dass zumindest der Freiheitsgrad in Einsteckrichtung blockiert wird, wenn das Kodiergehäuse mit dem Steckerkörper verbunden ist.Instead of a rail system, any guide can also be provided which ensures that at least the degree of freedom is blocked in the insertion direction when the coding housing is connected to the plug body.

Ein Schienensystem hat sich als besonders vorteilhaft erwiesen, um das Kodiergehäuse in einer aufschiebenden Montagebewegung auf den Steckerkörper aufzubringen, wobei die Montagebewegung erfindungsgemäß von der Einsteckrichtung des kompatiblen Steckverbinders abweicht.A rail system has proven to be particularly advantageous in order to apply the coding housing to the plug body in a deferred assembly movement, the assembly movement according to the invention deviating from the insertion direction of the compatible plug connector.

Durch ein Schienensystem kann gegebenenfalls ein weiterer Formschluss, orthogonal zur Einsteckrichtung bereitgestellt werden, wodurch bereits zwei Translationsfreiheitsgrade zwischen Kodiergehäuse und Steckerkörper blockiert werden können.A further form fit, orthogonal to the insertion direction, can optionally be provided by a rail system, whereby two degrees of translational freedom can be blocked between the coding housing and the plug body.

Alternativ oder zusätzlich kann auch eine Verbindungseinrichtung in der Art eines Bajonettverschlusses vorgesehen sein, wodurch das Kodiergehäuse durch eine drehende Montagebewegung auf den Steckerkörper aufgebracht werden kann. Eine Verbindungseinrichtung in Form eines Schienensystems ist jedoch zur Vereinfachung der Montage vorzuziehen.Alternatively or additionally, a connection device in the form of a bayonet lock can also be provided, whereby the coding housing can be attached to the plug body by a rotating assembly movement. However, a connection device in the form of a rail system is preferable to simplify assembly.

In einer Weiterbildung kann vorgesehen sein, dass In dem Kodiergehäuse und in dem Steckerkörper jeweils zwei parallel und an gegenüberliegenden Seiten verlaufende Führungsschienen angeordnet sind.In a further development it can be provided that two parallel guide rails running on opposite sides are arranged in the coding housing and in the plug body.

Grundsätzlich kann eine beliebige Anzahl Führungsschienen in Kodiergehäuse und Steckerkörper vorgesehen sein, insbesondere auch nur jeweils eine einzige Führungsschiene in Kodiergehäuse und Steckerkörper.In principle, any number of guide rails can be provided in the coding housing and plug body, in particular only a single guide rail in each case in the coding housing and plug body.

Eine besonders gute Führung lässt sich allerdings durch zumindest zwei parallel verlaufende Führungsschienen jeweils im Kodiergehäuse und im Steckerkörper erreichen. Dabei kann es besonders vorteilhaft sein (allerdings nicht unbedingt notwendig), die parallel verlaufenden Führungsschienen möglichst weit voneinander zu beabstanden, insbesondere zwei Führungsschienen an gegenüberliegenden Enden einer Seite des Kodiergehäuses und zwei hierzu korrespondierende Führungsschienen am gegenüberliegenden Ende einer Seite des Steckerkörpers vorzusehen. Vorzugsweise sind somit an den Enden/Rändern der zusammenzuschließenden Seiten des Kodiergehäuses und des Steckerkörpers parallel verlaufende Führungsschienen vorgesehen.However, particularly good guidance can be achieved by at least two parallel guide rails in the coding housing and in the plug body. It can be particularly advantageous (but not absolutely necessary) to space the parallel guide rails as far apart as possible, in particular to provide two guide rails at opposite ends of one side of the coding housing and two corresponding guide rails at the opposite end of one side of the connector body. Thus, parallel guide rails are preferably provided at the ends / edges of the sides of the coding housing and the plug body to be joined together.

Die Führungsschienen können beispielsweise miteinander korrespondieren, indem einerseits (im Kodiergehäuse oder im Steckerkörper) eine Nut und andererseits (im Steckerkörper oder im Kodiergehäuse) ein die Nut hintergreifender Steg vorgesehen ist. Alternativ oder zusätzlich kann ein Schienensystem auch durch eine klammerartige Ausbildung des Kodiergehäuses oder des Steckerkörpers realisiert sein, wodurch das jeweilige Gegenstück direkt geführt werden kann.The guide rails can correspond to one another, for example, by providing a groove on the one hand (in the coding housing or in the plug body) and on the other hand (in the plug body or in the coding housing) a web engaging behind the groove. Alternatively or in addition, a rail system can also be implemented by means of a clamp-like design of the coding housing or the plug body, whereby the respective counterpart can be guided directly.

In einer Weiterbildung der Erfindung kann vorgesehen sein, dass die Verbindungseinrichtung einen Endanschlag umfasst, der für die Montagebewegung eine Endposition des Kodiergehäuses an dem Steckerkörper festlegt.In a development of the invention, it can be provided that the connecting device comprises an end stop which defines an end position of the coding housing on the plug body for the assembly movement.

Der Montagevorgang, insbesondere die Ausrichtung des Kodiergehäuses und des Steckerkörpers relativ zueinander als Vorbereitung für mögliche weitere Montageschritte kann durch die Verwendung eines Endanschlags besonders vorteilhaft durchgeführt werden. Der Endanschlag kann vorzugsweise derart gestaltet sein, dass das Kodiergehäuse nur bis zu einer vorgesehenen Endposition auf den Steckerkörper aufgeschoben werden kann. Es kann also ein weiterer Formschluss bereitgestellt werden. In Kombination mit einem Schienensystem kann somit vorgesehen sein, dass zwischen Kodiergehäuse und Steckerkörper nach dem Aufschieben nur noch ein Translationsfreiheitsgrad verbleibt, wodurch nur noch eine Bewegung des Kodiergehäuses auf dem Steckerkörper entgegen die Aufschieberichtung möglich ist.The assembly process, in particular the alignment of the coding housing and the plug body relative to one another in preparation for possible further assembly steps, can be carried out particularly advantageously by using an end stop. The end stop can preferably be designed in such a way that the coding housing can only be pushed onto the plug body up to an intended end position. A further form fit can therefore be provided. In combination with a rail system, it can thus be provided that only one degree of translational freedom remains between the coding housing and the plug body after it has been pushed on, whereby only a movement of the coding housing on the plug body is possible against the pushing-on direction.

In einer Weiterbildung der Erfindung kann insbesondere vorgesehen sein, dass die Montagebewegung entlang eines Montagewinkels erfolgt, wobei der Montagewinkel relativ zu der Einsteckrichtung 30° bis 150°, vorzugsweise 45° bis 135°, besonders bevorzugt 80° bis 100° und ganz besonders bevorzugt 90° beträgt.In a further development of the invention it can be provided in particular that the assembly movement takes place along an assembly angle, the assembly angle relative to the insertion direction being 30 ° to 150 °, preferably 45 ° to 135 °, particularly preferably 80 ° to 100 ° and most particularly preferably 90 ° is.

Besonders eignet sich eine Montagebewegung, beispielsweise ein Aufschieben entlang eines Schienensystems, orthogonal oder zumindest annähernd orthogonal zu der Einsteckrichtung des kompatiblen Steckverbinders. Bei Verwendung eines orthogonal bzw. 90° zu der Einsteckrichtung ausgerichteten Schienensystems kann hierdurch inhärent ein besonders geeigneter Formschluss in Einsteckrichtung entstehen.An assembly movement is particularly suitable, for example sliding it on along a rail system, orthogonally or at least approximately orthogonally to the insertion direction of the compatible plug connector. When using an orthogonal or 90 ° to the insertion direction Aligned rail system can inherently create a particularly suitable form fit in the insertion direction.

In einer Weiterbildung kann vorgesehen sein, dass der Steckerkörper zur Aufnahme eines oder mehrerer Innenleiterteile ausgebildet ist, wobei der wenigstens eine Kontaktkörper als rohrförmiger Außenleiter und zur Aufnahme wenigstens eines der mehreren Innenleiterteile ausgebildet ist.In a development it can be provided that the plug body is designed to receive one or more inner conductor parts, the at least one contact body being designed as a tubular outer conductor and to receive at least one of the plurality of inner conductor parts.

Somit kann innerhalb des elektrischen Steckverbinders vorteilhaft wenigstens eine koaxiale Leitung bzw. eine Schirmung eines oder mehrerer Innenleiter durch einen als Außenleiter ausgebildeten Kontaktkörper bereitgestellt werden.In this way, at least one coaxial line or shielding of one or more inner conductors can advantageously be provided within the electrical plug connector by a contact body designed as an outer conductor.

In einer Weiterbildung kann ferner vorgesehen sein, dass das Kodiergehäuse und/oder der Steckerkörper ausgebildet ist, um ein bis zehn Kontaktkörper, vorzugsweise zwei bis sechs Kontaktkörper und ganz besonders bevorzugt vier Kontaktkörper aufzunehmen.In a further development, it can also be provided that the coding housing and / or the plug body is designed to accommodate one to ten contact bodies, preferably two to six contact bodies and very particularly preferably four contact bodies.

Insbesondere kann die Erfindung vorteilhaft zur Verwendung mit einem Kontaktkörper, zwei Kontaktkörpern oder vier Kontaktkörpern, insbesondere bei einer Ausbildung der Kontaktkörper als rohrförmige Außenleiter zur Aufnahme einer entsprechenden Anzahl Innenleiter, vorgesehen sein.In particular, the invention can advantageously be provided for use with one contact body, two contact bodies or four contact bodies, in particular when the contact bodies are designed as tubular outer conductors to accommodate a corresponding number of inner conductors.

In einer Weiterbildung kann außerdem vorgesehen sein, dass der Steckerkörper aus Metall, vorzugsweise als Zinkdruckgussteil ausgebildet und elektrisch leitend mit dem wenigstens einen Kontaktkörper verbunden ist.In a further development, it can also be provided that the plug body is made of metal, preferably designed as a zinc die-cast part, and is electrically conductively connected to the at least one contact body.

Insbesondere wenn der wenigstens eine Kontaktkörper als Außenleiter verwendet wird, ist die Ausbildung des Steckerkörpers aus Metall zur gemeinsamen Kontaktierung aller Kontaktkörper und zur elektromagnetischen Schirmung der durch den Steckerkörper geführten Innenleiterteile besonders vorteilhaft.In particular, when the at least one contact body is used as an outer conductor, the connector body is made of metal for common contacting of all contact bodies and for electromagnetic contact Shielding of the inner conductor parts passed through the plug body is particularly advantageous.

In einer Weiterbildung der Erfindung kann, wie bereits vorstehend erwähnt, der Steckerkörper zur elektrischen und mechanischen Verbindung mit einer als Leiterplatte, elektrisches Kabel, Adapterteil oder Gerätegehäuse ausgebildeten elektrischen Baugruppe ausgebildet sein.In a further development of the invention, as already mentioned above, the plug body can be designed for electrical and mechanical connection with an electrical assembly designed as a circuit board, electrical cable, adapter part or device housing.

Unter einem Adapterteil ist insbesondere ein Adapter-Kodiergehäuse zu verstehen, das beispielsweise eine von dem kompatiblen Steckverbinder abweichende mechanische Kodierung oder elektrische Konfiguration aufweist, und in das ein korrespondierender Steckverbinder eingesteckt werden kann. Dabei kann das Adapter-Kodiergehäuse ggf. auch über eine weitere mechanische Verbindungseinrichtung mit dem Steckerkörper des erfindungsgemäßen Steckverbinders verbunden sein, wofür beispielsweise ein weiteres Schienensystem vorgesehen sein kann.An adapter part is to be understood in particular as an adapter coding housing which, for example, has a mechanical coding or electrical configuration that differs from the compatible plug connector and into which a corresponding plug connector can be inserted. The adapter coding housing can optionally also be connected to the plug body of the plug connector according to the invention via a further mechanical connection device, for which purpose a further rail system can be provided, for example.

In einer Weiterbildung der Erfindung kann schließlich vorgesehen sein, dass das Kodiergehäuse Rastmittel zur rastenden Verbindung mit dem kompatiblen Steckverbinder aufweist.In a further development of the invention, it can finally be provided that the coding housing has latching means for latching connection with the compatible plug connector.

Auf diese Weise kann verhindert werden, dass unerwünschte Zugkräfte entgegen der Einsteckrichtung zu einem Ausstecken des kompatiblen Steckverbinders führen, sondern vielmehr auf das Kodiergehäuse und durch die erfindungsgemäße Verbindungseinrichtung direkt auf den Steckerkörper und somit auf die elektrische Baugruppe übertragen und abgefangen werden.In this way it can be prevented that undesired tensile forces against the plug-in direction lead to unplugging of the compatible connector, but rather are transmitted and intercepted on the coding housing and through the connecting device according to the invention directly on the connector body and thus on the electrical assembly.

Der Steckerkörper und/oder das Kodiergehäuse können gerade oder winklig ausgebildet sein; die Erfindung ist somit für einen geraden als auch für einen winkligen Steckverbinder gleichermaßen verwendbar. Es kommt im Sinne der Erfindung lediglich darauf an, dass die Montagebewegung für das Kodiergehäuse und den Steckerkörper von der Einsteckrichtung des kompatiblen Steckverbinders abweicht.The plug body and / or the coding housing can be straight or angled; the invention can thus be used equally for a straight connector as well as for an angled connector. For the purposes of the invention, it is only important that the assembly movement for the coding housing and the plug body deviates from the insertion direction of the compatible plug connector.

Die Erfindung kann außerdem vorteilhaft dafür verwendet werden, einen modularen Baukasten aus Kodiergehäusen zur Verfügung zu stellen, die von einem Monteur nach Bedarf mit einem einheitlichen Steckerkörper verbunden werden können. Somit kann der Monteur sehr einfach verschiedene Konfigurationen bzw. Variationen des elektrischen Steckverbinders erzeugen, bei gleichbleibendem und ggf. sogar vormontiertem Steckerkörper.The invention can also be used advantageously to provide a modular construction kit of coding housings which can be connected by a fitter to a uniform plug body as required. In this way, the fitter can very easily create different configurations or variations of the electrical connector, with the connector body remaining the same and possibly even pre-assembled.

Es kann vorgesehen sein, zusätzlich zu dem wenigstens einen Innenleiterteil eine das Innenleiterteil umgebende isolierende Materialschicht zumindest in den Steckerkörper einzubringen, die das wenigstens eine Innenleiterteil in Position hält und Kurzschlüsse mit weiteren Innenleiterteilen und/oder einer Masseleitung verhindert.It can be provided, in addition to the at least one inner conductor part, to introduce an insulating material layer surrounding the inner conductor part at least into the plug body, which holds the at least one inner conductor part in position and prevents short circuits with other inner conductor parts and / or a ground line.

Die Erfindung ist nicht auf eine spezifische Steckverbinderart bzw. auf einen spezifischen Steckverbinder beschränkt, wobei sich die Erfindung insbesondere für die Konfektionierung von HF-Kabeln eignet. Der Steckverbinder kann dabei vorzugsweise als HF-Steckverbinder insbesondere als PL-Steckverbinder, BNC-Steckverbinder, TNC-Steckverbinder, SMBA(Fakra)-Steckverbinder, N-Steckverbinder, 7-16-Steckverbinder, SMA-Steckverbinder, SMB-Steckverbinder, SMS-Steckverbinder, SMC-Steckverbinder, SMP-Steckverbinder, BMS-Steckverbinder, HFM-Steckverbinder, HSD-Steckverbinder, BMK-Steckverbinder, Mini-Coax-Steckverbinder oder Makax-Steckverbinder ausgebildet sein.The invention is not limited to a specific type of connector or to a specific connector, the invention being particularly suitable for assembling HF cables. The connector can be used as an HF connector, in particular as a PL connector, BNC connector, TNC connector, SMBA (Fakra) connector, N connector, 7-16 connector, SMA connector, SMB connector, SMS connector Connectors, SMC Connectors, SMP Connectors, BMS Connectors, HFM Connectors, HSD connectors, BMK connectors, mini-coax connectors or Makax connectors can be designed.

Die Erfindung betrifft auch ein Verfahren zur Montage eines elektrischen Steckverbinders, der ein Kodiergehäuse zur elektrischen und mechanischen Verbindung mit einem kompatiblen Steckverbinder und einem Steckerkörper zur elektrischen und mechanischen Verbindung mit einer elektrischen Baugruppe aufweist, wobei das Kodiergehäuse in einem Montageschritt mit dem Steckerkörper mechanisch verbunden wird.The invention also relates to a method for assembling an electrical connector which has a coding housing for electrical and mechanical connection to a compatible connector and a connector body for electrical and mechanical connection to an electrical assembly, the coding housing being mechanically connected to the connector body in an assembly step .

Bei dem erfindungsgemäßen Verfahren ist vorgesehen, dass der Montageschritt zur Herstellung der mechanischen Verbindung zwischen dem Kodiergehäuse und dem Steckerkörper eine Montagebewegung des Kodiergehäuses relativ zu dem Steckerkörper umfasst, durch welche das Kodiergehäuse und der Steckerkörper in Einsteckrichtung des kompatiblen Steckverbinders formschlüssig miteinander verbunden werden.In the method according to the invention, it is provided that the assembly step for establishing the mechanical connection between the coding housing and the plug body comprises an assembly movement of the coding housing relative to the plug body, by means of which the coding housing and the plug body are positively connected to one another in the insertion direction of the compatible plug connector.

Merkmale, die bereits im Zusammenhang mit dem erfindungsgemäßen Steckverbinder beschrieben wurden, sind selbstverständlich auch für das erfindungsgemäße Verfahren bzw. das nachfolgend noch beschriebene Steckverbindersystem vorteilhaft umsetzbar - und umgekehrt. Ferner können Vorteile, die bereits im Zusammenhang mit dem erfindungsgemäßen Steckverbinder genannt wurden, auch auf das erfindungsgemäße Verfahren bzw. auf das Steckverbindersystem bezogen verstanden werden - und umgekehrt.Features that have already been described in connection with the plug connector according to the invention can of course also be implemented advantageously for the method according to the invention or the plug connector system described below - and vice versa. Furthermore, advantages that have already been mentioned in connection with the plug connector according to the invention can also be understood in relation to the method according to the invention or to the plug connector system - and vice versa.

In einer Weiterbildung des erfindungsgemäßen Verfahrens kann vorgesehen sein, dass die Montagebewegung ein Aufschieben des Kodiergehäuses auf den Steckerkörper und/oder eine Verdrehung des Kodiergehäuses gegenüber dem Steckerkörper umfasst.In a further development of the method according to the invention, it can be provided that the assembly movement involves pushing on the coding housing on the plug body and / or a rotation of the coding housing with respect to the plug body.

In einer Weiterbildung des Verfahrens kann insbesondere vorgesehen sein, dass das Aufschieben des Kodiergehäuses auf den Steckerkörper unter Verwendung des zuvor erwähnten Schienensystems erfolgt, wobei das Kodiergehäuse und der Steckerkörper jeweils wenigstens eine miteinander korrespondierende Führungsschiene aufweisen.In a further development of the method it can be provided in particular that the coding housing is pushed onto the connector body using the aforementioned rail system, the coding housing and the connector body each having at least one corresponding guide rail.

In einer Weiterbildung des Verfahrens kann insbesondere vorgesehen sein, dass das Aufschieben entlang eines Montagewinkels erfolgt, wobei der Montagewinkel relativ zu der Einsteckrichtung 30° bis 150°, vorzugsweise 45° bis 135°, besonders bevorzugt 80° bis 100° und ganz besonders bevorzugt 90° beträgt.In a further development of the method, it can be provided in particular that the sliding takes place along a mounting bracket, the mounting bracket relative to the insertion direction being 30 ° to 150 °, preferably 45 ° to 135 °, particularly preferably 80 ° to 100 ° and very particularly preferably 90 ° is.

Im Hinblick auf eine Verdrehung des Kodiergehäuses kann eine Verbindungseinrichtung in der Art eines Bajonettverschlusses vorgesehen sein.With regard to a rotation of the coding housing, a connecting device in the form of a bayonet lock can be provided.

In einer vorteilhaften Weiterbildung des erfindungsgemäßen Verfahrens kann vorgesehen sein, dass in einem weiteren Montageschritt wenigstens ein Kontaktkörper in Einsteckrichtung durch korrespondierende Ausnehmungen in dem Kodiergehäuse und in dem Steckerkörper eingebracht wird, derart, dass die relative Position zwischen dem Kodiergehäuse und dem Steckerkörper fixiert wird.In an advantageous development of the method according to the invention, it can be provided that in a further assembly step at least one contact body is introduced in the insertion direction through corresponding recesses in the coding housing and in the plug body, such that the relative position between the coding housing and the plug body is fixed.

Eine Feinjustierung des erfindungsgemäßen Steckverbinders kann vorteilhaft durch Verwendung bzw. durch das Einbringen des wenigstens einen Kontaktkörpers erfolgen.A fine adjustment of the connector according to the invention can advantageously take place by using or by introducing the at least one contact body.

In einer Weiterbildung hierzu kann insbesondere vorgesehen sein, dass der wenigstens eine Kontaktkörper in der Ausnehmung des Steckerkörpers verpresst, verlötet, verschweißt, verschmolzen und/oder verklebt wird.In a development of this, it can be provided in particular that the at least one contact body is pressed, soldered, welded, fused and / or glued in the recess of the plug body.

Vorzugsweise wird der wenigstens eine Kontaktkörper, bei dem es sich vorzugsweise um eine Kontakthülse handelt, in die Ausnehmungen des Steckerkörpers eingepresst.The at least one contact body, which is preferably a contact sleeve, is preferably pressed into the recesses of the plug body.

Dabei kommt es weniger auf die Art der Befestigung des Kontaktkörpers in dem Steckerkörper als vielmehr darauf an, dass der wenigstens eine Kontaktkörper derart eingebracht wird, dass der korrespondierende Kraftschluss (und/oder Stoffschluss) des wenigstens einen Kontaktkörpers mit dem Steckerkörper die Zugkraft, die bei einem Ausstecken des kompatiblen Steckverbinders auf den Kontaktkörper wirkt, übersteigt. Der Kontaktkörper kann somit sicher an seiner Position in dem Steckerkörper gehalten werden.It depends less on the type of attachment of the contact body in the plug body than on the fact that the at least one contact body is introduced in such a way that the corresponding frictional connection (and / or material connection) of the at least one contact body with the plug body reduces the tensile force that occurs at unplugging the compatible connector acts on the contact body, exceeds. The contact body can thus be held securely in its position in the plug body.

In einer Weiterbildung kann vorgesehen sein, dass in einem weiteren Montageschritt wenigstens ein Innenleiterteil durch den Steckerkörper geführt und von dem wenigstens einen Kontaktkörper aufgenommen wird.In a development it can be provided that in a further assembly step at least one inner conductor part is passed through the plug body and is received by the at least one contact body.

In einem weiteren Montageschritt kann der elektrische Steckverbinder an der elektrischen Baugruppe befestigt werden. Beispielsweise können ausgangsseitige Kontakte mit einer Leiterplatte verlötet oder mit Litzen eines elektrischen Kabels vercrimpt werden, wodurch gleichzeitig auch die elektrische Kontaktierung erfolgen kann.In a further assembly step, the electrical connector can be attached to the electrical assembly. For example, contacts on the output side can be soldered to a printed circuit board or crimped with strands of an electrical cable, so that electrical contact can also be made at the same time.

Grundsätzlich - je nach Aufbau des Steckverbinders - kann auch eine abweichende Reihenfolge der beschriebenen Montageschritte vorgesehen sein. Beispielsweise kann der Steckerkörper ggf. bereits an der elektrischen Baugruppe vormontiert sein.In principle - depending on the structure of the connector - a different sequence of the assembly steps described can also be provided. For example, the plug body can possibly already be preassembled on the electrical assembly.

Die Erfindung betrifft auch ein Steckverbindersystem, umfassend einen elektrischen Steckverbinder gemäß den vorstehenden Ausführungen, einen kompatiblen Steckverbinder zur elektrischen und mechanischen Verbindung mit einem Kodiergehäuse des Steckverbinders und eine elektrische Baugruppe zur elektrischen und mechanischen Verbindung mit einem Steckerkörper des Steckverbinders.The invention also relates to a connector system, comprising an electrical connector according to the preceding statements, a compatible connector for electrical and mechanical connection with a coding housing of the connector and an electrical assembly for electrical and mechanical connection with a connector body of the connector.

Figur 1 zeigt ein erfindungsgemäßes Steckverbindersystem 1, umfassend einen erfindungsgemäßen elektrischen Steckverbinder 2, einen kompatiblen Steckverbinder 3 zur elektrischen und mechanischen Verbindung mit einem Kodiergehäuse 4 des erfindungsgemäßen Steckverbinders 2 und eine als Leiterplatte (gestrichelt dargestellt) ausgebildete elektrische Baugruppe 5 zur elektrischen und mechanischen Verbindung mit einem Steckerkörper 6 des erfindungsgemäßen Steckverbinders 2. Figure 1 shows a connector system 1 according to the invention, comprising an electrical connector 2 according to the invention, a compatible connector 3 for electrical and mechanical connection with a coding housing 4 of the connector 2 according to the invention and an electrical assembly 5 designed as a printed circuit board (shown in dashed lines) for electrical and mechanical connection with a connector body 6 of the connector 2 according to the invention.

Der kompatible Steckverbinder 3 ist entlang einer Einsteckrichtung A, in den Figuren durch entsprechende Pfeile angedeutet, entlang der Achse Ax mit dem Kodiergehäuse 4 verbindbar. Bei der Achse Ax handelt es sich vorzugsweise (wie im Ausführungsbeispiel der Fall) um die Längsachse des Kodiergehäuses 4.The compatible plug connector 3 can be connected to the coding housing 4 along the axis A x along an insertion direction A, indicated in the figures by corresponding arrows. The axis A x is preferably (as is the case in the exemplary embodiment) the longitudinal axis of the coding housing 4.

Der kompatible Steckverbinder 3 ist in der Figur 1 beispielhaft gestrichelt dargestellt. Üblicherweise wird der kompatible Steckverbinder 3 erst dann mit dem erfindungsgemäßen Steckverbinder 2 verbunden, wenn der erfindungsgemäßen Steckverbinder 2 fertig montiert ist. Nur zur Veranschaulichung und zur vollständigen Darstellung des Steckverbindungssystems, ist der kompatible Steckverbinder 3 bereits im unmontierten Zustand des elektrischen Steckverbinders 2 in Figur 1 dargestellt.The compatible connector 3 is in the Figure 1 exemplified by dashed lines. The compatible connector 3 is usually only then connected to the connector 2 according to the invention when the connector 2 according to the invention is fully assembled. The compatible connector 3 is already shown in FIG. 1 in the unmounted state of the electrical connector 2 for the purpose of illustration and for the complete representation of the plug connection system Figure 1 shown.

Im Ausführungsbeispiel weisen der kompatible Steckverbinder 3 und das Kodiergehäuse 4 jeweils Rastmittel 7 zur gegenseitig rastenden Verbindung auf. Diese können grundsätzlich aber auch entfallen bzw. anderweitig ausgebildet sein. Das Kodiergehäuse 4 des erfindungsgemäßen Steckverbinders 2 kann eine mechanische Kodierung und eine elektrische Konfiguration aufweisen, die mit dem kompatiblen Steckverbinder 3 bzw. mit einem Kodiergehäuse des kompatiblen Steckverbinders 3 korrespondiert, um elektrische Signale (Daten und Versorgung) möglichst optimal weiterzuleiten und um sicherzustellen, dass nur ein kompatibler Steckverbinder 3 mit dem erfindungsgemäßen Steckverbinder 2 zusammensteckbar ist.In the exemplary embodiment, the compatible connector 3 and the coding housing 4 each have locking means 7 for mutually locking connection. In principle, however, these can also be omitted or configured differently. The coding housing 4 of the connector 2 according to the invention can have a mechanical coding and an electrical configuration which corresponds to the compatible connector 3 or to a coding housing of the compatible connector 3 in order to forward electrical signals (data and supply) as optimally as possible and to ensure that only one compatible connector 3 can be plugged together with the connector 2 according to the invention.

Der Steckerkörper 6 der Ausführungsform der Figur 1 ist zur elektrischen und mechanischen Verbindung mit einer Leiterplatte 5 ausgebildet. Die elektrische und mechanische Verbindung kann beispielsweise durch eine Lötkontaktierung erfolgen (vgl. Figur 14). Üblicherweise wird der erfindungsgemäßen Steckverbinder 2 erst nach der Montage mit der elektrischen Baugruppe bzw. mit der Leiterplatte 5 verbunden. Die Leiterplatte 5 ist im Wesentlichen zur Veranschaulichung bereits im unmontierten Zustand des erfindungsgemäßen Steckverbinders 2 in Figur 1 dargestellt.The plug body 6 of the embodiment of Figure 1 is designed for electrical and mechanical connection to a circuit board 5. The electrical and mechanical connection can be made, for example, by solder contact (cf. Figure 14 ). The connector 2 according to the invention is usually only connected to the electrical assembly or to the printed circuit board 5 after assembly. The circuit board 5 is essentially for the purpose of illustration already in the unmounted state of the connector 2 according to the invention in Figure 1 shown.

Das Kodiergehäuse 4 und der Steckerkörper 6 weisen eine mechanische Verbindungseinrichtung 8 auf, die ausgebildet ist, um das Kodiergehäuse 4 und den Steckerkörper 6 in Einsteckrichtung A formschlüssig miteinander zu verbinden, wobei die Verbindungseinrichtung 8 eine von der Einsteckrichtung A abweichende Montagebewegung B für das Kodiergehäuse 4 und den Steckerkörper 6 vorgibt (in den Figuren durch entsprechende Pfeile angedeutet). Die Verbindungseinrichtung 8 ist im Bereich der Verbindungsflächen 13 des Kodiergehäuses 4 bzw. des Steckerkörpers 6 angeordnet, die miteinander mechanisch verbunden werden sollen.The coding housing 4 and the plug body 6 have a mechanical connecting device 8 which is designed to connect the coding housing 4 and the plug body 6 to one another in a form-fitting manner in the insertion direction A, the connecting device 8 having an assembly movement B for the coding housing 4 that deviates from the insertion direction A and the plug body 6 specifies (indicated in the figures by corresponding arrows). The connecting device 8 is arranged in the area of the connecting surfaces 13 of the coding housing 4 or of the plug body 6, which are to be mechanically connected to one another.

Im Zuge eines Verfahrens zur Montage des erfindungsgemäßen Steckverbinders 2 ist somit in einem Montageschritt, zumeist aber nicht zwingend im ersten Montageschritt, das Kodiergehäuse 4 mit dem Steckerkörper 6 mechanisch zu verbinden. Dieser Montageschritt zur Herstellung der mechanischen Verbindung zwischen dem Kodiergehäuse 4 und dem Steckerkörper 6 umfasst dabei eine Montagebewegung B, durch welche das Kodiergehäuse 4 und der Steckerkörper 6 in Einsteckrichtung A des kompatiblen Steckverbinders 3 formschlüssig miteinander verbunden werden.In the course of a method for assembling the connector 2 according to the invention, the coding housing 4 is mechanically connected to the connector body 6 in an assembly step, but mostly not necessarily in the first assembly step. This assembly step for establishing the mechanical connection between the coding housing 4 and the plug body 6 comprises an assembly movement B by which the coding housing 4 and the plug body 6 are positively connected to one another in the insertion direction A of the compatible plug connector 3.

Die Montagebewegung B kann ein Aufschieben des Kodiergehäuses 4 auf den Steckerkörper 6 und/oder eine Verdrehung des Kodiergehäuses 4 gegenüber dem Steckerkörper 6 umfassen. In den Ausführungsbeispielen wird lediglich die bevorzugte Variante des Aufschiebens dargestellt, dies ist allerdings nicht einschränkend zu verstehen.The assembly movement B can include pushing the coding housing 4 onto the plug body 6 and / or rotating the coding housing 4 with respect to the plug body 6. In the exemplary embodiments, only the preferred variant of sliding is shown, but this is not to be understood as limiting.

Im Ausführungsbeispiel ist die Verbindungseinrichtung 8 als Schienensystem ausgebildet, wobei das Kodiergehäuse 4 und der Steckerkörper 6 miteinander korrespondierende Führungsschienen 9, 10 aufweisen, die gemeinsam das Schienensystem bzw. die Verbindungseinrichtung 8 ausbilden. Das Aufschieben des Kodiergehäuses 4 auf den Steckerkörper 6 erfolgt somit unter Verwendung des genannten Schienensystems. Eine der verdeckten Führungsschienen 10 des Steckerkörpers 6 ist in Figur 1 als gestrichelte Linie angedeutet.In the exemplary embodiment, the connecting device 8 is designed as a rail system, the coding housing 4 and the plug body 6 have mutually corresponding guide rails 9, 10, which together form the rail system or the connecting device 8. The coding housing 4 is thus pushed onto the plug body 6 using the rail system mentioned. One of the concealed guide rails 10 of the plug body 6 is shown in FIG Figure 1 indicated as a dashed line.

Es kann vorgesehen sein, dass die Montagebewegung B bzw. das Aufschieben des Kodiergehäuses auf den Steckerkörper entlang eines Montagewinkels α erfolgt, wobei der Montagewinkel α relativ zu der Einsteckrichtung A 30° bis 150°, vorzugsweise 45° bis 135°, besonders bevorzugt 80° bis 100° und ganz besonders bevorzugt 90° beträgt. Im Ausführungsbeispiel wird durchgängig ein Montagewinkel α von 90° verwendet, der sich als besonders geeignet für die formschlüssige Verbindung in Einsteckrichtung A erwiesen hat. Dies ist allerdings nicht einschränkend zu verstehen. Grundsätzlich können beliebige Montagewinkel α vorgesehen sein. Es kommt lediglich darauf an, dass das Aufschieben bzw. die Montagebewegung B nicht in Einsteckrichtung A des kompatiblen Steckverbinders 3 erfolgt. Grundsätzlich kann das Aufschieben auch entlang eines spezifischen Montagepfades erfolgen und muss nicht einen streng linearen Verlauf, wie im Ausführungsbeispiel dargestellt, aufweisen.It can be provided that the assembly movement B or the pushing of the coding housing onto the plug body takes place along an assembly angle α, the assembly angle α relative to the insertion direction A being 30 ° to 150 °, preferably 45 ° to 135 °, particularly preferably 80 ° to 100 ° and very particularly preferably 90 °. In the exemplary embodiment, a mounting angle α of 90 ° is used throughout, which has proven to be particularly suitable for the positive connection in the insertion direction A. However, this is not to be understood as restrictive. In principle, any mounting angle α can be provided. All that matters is that the pushing on or the assembly movement B does not take place in the insertion direction A of the compatible plug connector 3. In principle, the pushing on can also take place along a specific assembly path and does not have to have a strictly linear course, as shown in the exemplary embodiment.

Der in Figur 1 dargestellte erfindungsgemäße Steckverbinder 2 ist in Figur 2 gesondert von dem Steckverbindersystem 1 der Figur 1 in einer Vorderansicht dargestellt. Dabei ist erkennbar, dass in dem Steckerkörper 6 je zwei parallel verlaufende Führungsschienen 10 an gegenüberliegenden Enden der Verbindungsfläche 13 des Steckerkörpers 6 verlaufend angeordnet sind, die mit entsprechend parallel verlaufenden und ebenfalls an gegenüberliegenden Enden der Verbindungsfläche 13 angeordneten Führungsschienen 9 des Kodiergehäuses 4 korrespondieren (nicht dargestellt). Durch die Verwendung von jeweils zwei Führungsschienen 9, 10 kann eine besonders geeignete Führung bereitgestellt werden. Das Schienensystem bzw. die Führungsschienen 9, 10 und deren Anordnung sind besonders gut in den nachfolgend noch erläuterten Figuren 9 bis 11 erkennbar.The in Figure 1 illustrated connector 2 according to the invention is in Figure 2 separate from the connector system 1 of the Figure 1 shown in a front view. It can be seen that in the plug body 6, two parallel guide rails 10 are arranged at opposite ends of the connecting surface 13 of the plug body 6, which are correspondingly parallel and Guide rails 9 of the coding housing 4, likewise arranged at opposite ends of the connecting surface 13, correspond (not shown). By using two guide rails 9, 10 each, a particularly suitable guide can be provided. The rail system or the guide rails 9, 10 and their arrangement are particularly good in those explained below Figures 9 to 11 recognizable.

Ferner sind in dem Kodiergehäuse 4 und in dem Steckerkörper 6 Ausnehmungen 11 für wenigstens einen nachfolgend noch beschriebenen Kontaktkörper 12 vorgesehen, die in einer Endposition des Kodiergehäuses 4 vorzugsweise aufeinander ausgerichtet sind.Furthermore, recesses 11 are provided in the coding housing 4 and in the plug body 6 for at least one contact body 12, which will be described below and which are preferably aligned with one another in an end position of the coding housing 4.

In Figur 2 ist ferner ein zusätzlicher Vorteil des erfindungsgemäßen Steckverbinders 2 dargestellt. Aufgrund des zweiteiligen und dennoch robusten Aufbaus kann der erfindungsgemäßen Steckverbinder 2 in einem modularen Baukastensystem Verwendung finden, wonach ein Monteur sehr einfach aus einer Menge verschiedener Kodiergehäuse 4 ein gewünschtes Kodiergehäuse 4 auswählen kann und anschließend durch die mechanische Verbindungseinrichtung 8 mit dem Steckerkörper 6 verbindet. Vorzugsweise korrespondieren dabei die Positionen der Ausnehmungen 11 für den wenigstens einen Kontaktkörper 12; dies ist allerdings nicht zwingend erforderlich. Beispielweise kann ein Monteur anstatt einer Vierfachausführung bzw. einem Kodiergehäuse 4, dass zur Verwendung mit vier Kontaktkörpern 12 vorgesehen ist, auch ein Kodiergehäuse 4 auswählen, das zur Verwendung mit nur zwei Kontaktkörpern 12 vorgesehen ist. Ferner kann sich die mechanische Kodierung zwischen verschiedenen Kodiergehäusen 4 unterscheiden, wodurch die Kompatibilität mit dem kompatiblen Steckverbinder 3 von einem Monteur einfach bestimmt werden kann.In Figure 2 an additional advantage of the connector 2 according to the invention is also shown. Due to the two-part and yet robust construction, the connector 2 according to the invention can be used in a modular system, according to which a fitter can very easily select a desired coding housing 4 from a set of different coding housings 4 and then connect it to the connector body 6 through the mechanical connecting device 8. The positions of the recesses 11 for the at least one contact body 12; however, this is not absolutely necessary. For example, instead of a quadruple design or a coding housing 4 that is intended for use with four contact bodies 12, a fitter can also select a coding housing 4 that is intended for use with only two contact bodies 12. Furthermore, the mechanical coding can differ between different coding housings 4, which increases the compatibility can be easily determined by a fitter with the compatible connector 3.

Grundsätzlich kann die Montagebewegung B, insbesondere bezüglich eines Aufschiebens entlang eines Schienensystems, in eine beliebige Richtung erfolgen (außer in oder entgegen die Einsteckrichtung A). Dies ist bespielhaft in den Figuren 3 und 4 dargestellt.In principle, the assembly movement B, in particular with regard to sliding it on along a rail system, can take place in any direction (except in or against the insertion direction A). This is exemplary in the Figures 3 and 4 shown.

In Figur 3 wird das Kodiergehäuse ebenfalls mit einem Montagewinkel α von 90° zu der Einsteckrichtung A aufgeschoben, verglichen mit Figur 1 allerdings in die entgegengesetzte Richtung.In Figure 3 the coding housing is also pushed on with a mounting angle α of 90 ° to the insertion direction A, compared with Figure 1 but in the opposite direction.

In Figur 4 ist eine Variante für eine Montagebewegung B durch ein seitliches Aufschieben dargestellt, wobei das Schienensystem, verglichen mit den Figuren 1 bis 3, um 90° verdreht ist. Auch in dieser Ausführung findet die Montagebewegung B orthogonal beziehungsweise mit einem Montagewinkel α von 90° relativ zu der Einsteckrichtung A statt. Grundsätzlich kann das Schienensystem in einem beliebigen Winkel auf den Verbindungsflächen 13 des Kodiergehäuses 4 bzw. des Steckerkörpers 6 ausgerichtet sein.In Figure 4 a variant for an assembly movement B is shown by sliding it sideways, the rail system, compared with the Figures 1 to 3 is rotated by 90 °. In this embodiment, too, the assembly movement B takes place orthogonally or with an assembly angle α of 90 ° relative to the insertion direction A. In principle, the rail system can be oriented at any desired angle on the connecting surfaces 13 of the coding housing 4 or of the plug body 6.

Wie vorstehend bereits angedeutet kann die Erfindung bzw. der erfindungsgemäße Steckverbinder 2 für eine Vielzahl von Anwendungen geeignet sein. Beispielsweise kann der Steckerkörper 6 des erfindungsgemäßen Steckverbinders 2, der in den Figuren 1 bis 4 in einer winkligen Ausführung gezeigt ist, auch in einer geraden Ausführung ausgebildet sein. In den Figuren 5 bis 8 ist eine gerade Ausführung dargestellt.As already indicated above, the invention or the connector 2 according to the invention can be suitable for a large number of applications. For example, the plug body 6 of the connector 2 according to the invention, which is in the Figures 1 to 4 is shown in an angled design, can also be designed in a straight design. In the Figures 5 to 8 a straight version is shown.

Figur 5 zeigt einen geraden Leiterplattensteckverbinder, der zur elektrischen und mechanischen Verbindung mit einer Leiterplatte 5 (hier nicht dargestellt) ausgebildet ist. Figure 5 shows a straight circuit board connector which is designed for electrical and mechanical connection to a circuit board 5 (not shown here).

Figur 6 zeigt einen als Stecker ausgebildeten Steckverbinder 2, der zur elektrischen und mechanischen Verbindung mit einer als elektrisches Kabel 14 ausgebildeten elektrischen Baugruppe ausgebildet ist. Selbstverständlich kann anstelle eines Steckers auch eine Buchse bzw. eine Kupplung in Verbindung mit einem elektrischen Kabel 14 vorgesehen sein. Figure 6 shows a plug connector 2 designed as a plug, which is designed for electrical and mechanical connection to an electrical assembly designed as an electrical cable 14. Of course, instead of a plug, a socket or a coupling in connection with an electrical cable 14 can also be provided.

In Figur 7 ist der elektrische Steckverbinder 2 als Adapter dargestellt, wobei der Steckerkörper 6 zur elektrischen und mechanischen Verbindung mit einer als Adapterteil 15 ausgebildeten elektrischen Baugruppe realisiert ist. Bei dem Adapterteil 15 handelt es sich vorliegend um ein Adapter-Kodiergehäuse, das beispielsweise eine von dem Kodiergehäuse 4 abweichende mechanische Kodierung und/oder elektrische Konfiguration aufweist, um einen hiermit komplementären Steckverbinder (nicht dargestellt) mit dem kompatiblen Steckverbinder 3 in der Art eines Adapters zu verbinden. Dabei kann insbesondere auch vorgesehen sein, dass das Adapterteil 15 und der Steckerkörper 6 eine zweite Verbindungseinrichtung ausbilden (nicht dargestellt), wodurch auch das Adapterteil 15 mit dem Steckerkörper 6 verbindbar ist. Der Steckerkörper 6 kann aber auch einteilig mit dem Adapterteil 15 ausgebildet oder auf sonstige Weise mit dem Adapterteil 15 verbindbar sein.In Figure 7 the electrical connector 2 is shown as an adapter, the connector body 6 being implemented for electrical and mechanical connection to an electrical assembly designed as an adapter part 15. In the present case, the adapter part 15 is an adapter coding housing which, for example, has a mechanical coding and / or electrical configuration that differs from the coding housing 4, a connector complementary to this (not shown) with the compatible connector 3 in the form of an adapter connect to. In particular, it can also be provided that the adapter part 15 and the plug body 6 form a second connecting device (not shown), whereby the adapter part 15 can also be connected to the plug body 6. The plug body 6 can, however, also be designed in one piece with the adapter part 15 or can be connected to the adapter part 15 in some other way.

In Figur 8 ist der erfindungsgemäße Steckverbinder 2 schließlich als Gehäusestecker dargestellt, wobei der Steckerkörper 6 zur elektrischen und mechanischen Verbindung mit einer als Gerätegehäuse 16 ausgebildeten elektrischen Baugruppe realisiert ist.In Figure 8 the connector 2 according to the invention is finally shown as a housing connector, the connector body 6 for electrical and mechanical connection is realized with an electrical assembly designed as a device housing 16.

In Figur 9 ist der Steckverbinder 2 des Steckverbindungssystems 1 der Figur 1 gesondert in einer Draufsicht dargestellt, wodurch die Verbindungseinrichtung 8 bzw. das Schienensystem besonders gut sichtbar wird. Wie bereits ausgeführt weisen das Kodiergehäuse 4 und der Steckerkörper 6 jeweils zwei parallel und an gegenüberliegenden Enden der Verbindungsflächen 13 verlaufende Führungsschienen 9, 10 auf. Die Figuren 10 und 11 zeigen entsprechende Vergrößerungen auf jeweils eine Führungsschiene 9 des Kodiergehäuses 4 und eine Führungsschiene 10 des Steckerkörpers 6.In Figure 9 is the connector 2 of the connector system 1 of Figure 1 shown separately in a plan view, whereby the connecting device 8 or the rail system is particularly clearly visible. As already stated, the coding housing 4 and the plug body 6 each have two guide rails 9, 10 running parallel and at opposite ends of the connecting surfaces 13. FIGS. 10 and 11 show corresponding enlargements of a guide rail 9 of the coding housing 4 and a guide rail 10 of the plug body 6.

Grundsätzlich kann eine beliebige Führung vorgesehen sein, ein Schienensystem eignet sich allerdings in besonderer Weise. Schließlich kann das Schienensystem nahezu beliebig realisiert sein, beispielsweise wie in den Figuren 9 bis 11 dargestellt als ineinandergreifende Elemente bzw. indem der Steckerkörper 6 klammerartig angeordnete Führungsschienen 10 aufweist, die entsprechende Nuten 17 der Führungsschienen 9 des Kodiergehäuses 4 hintergreifen. Auch T-förmige Stege, die korrespondierende Nuten des Gegenstücks zu hintergreifen vermögen, sind möglich.In principle, any guide can be provided, but a rail system is particularly suitable. Finally, the rail system can be implemented in almost any way, for example as in the Figures 9 to 11 shown as interlocking elements or in that the plug body 6 has guide rails 10 arranged in a clamp-like manner, which engage behind corresponding grooves 17 in the guide rails 9 of the coding housing 4. T-shaped webs that are able to engage behind corresponding grooves of the counterpart are also possible.

Wie in den Figuren 9 und 10 erkennbar, weisen die Führungsschienen 9 des Kodiergehäuses 4 Endanschläge 18 auf, die für die Montagebewegung B eine Endposition des Kodiergehäuses 4 an dem Steckerkörper 6 festlegen. Grundsätzlich kann die Verbindungseinrichtung 8 einen beliebigen Endanschlag 18 umfassen. Es kann auch vorgesehen sein, dass der Steckerkörper 6 bzw. das Kodiergehäuse 4 Endanschläge aufweist.As in the Figures 9 and 10 As can be seen, the guide rails 9 of the coding housing 4 have end stops 18 which define an end position of the coding housing 4 on the plug body 6 for the assembly movement B. In principle, the connecting device 8 can comprise any end stop 18. It can also be provided that the plug body 6 or the coding housing 4 has end stops.

In Figur 12 ist ein weiterer Montageschritt, der vorzugsweise - aber nicht zwingend - auf den zuvor beschriebenen Montageschritt zur Herstellung der mechanischen Verbindung zwischen dem Kodiergehäuse 4 und dem Steckerkörper 6 folgt, dargestellt. Dabei werden Kontaktkörper 12 in Einsteckrichtung A durch korrespondierende Ausnehmungen 11 in dem Kodiergehäuse 4 und in dem Steckerkörper 6 in den Steckverbinder 2 eingebracht, derart dass die relative Position zwischen dem Kodiergehäuse 4 und dem Steckerkörper 6 fixiert wird. Die entsprechenden Ausnehmungen 11 sind in der vorher bereits beschriebenen Figur 2 in einer Vorderansicht gut erkennbar. In Figur 12 ist ein erster Kontaktkörper 12 bereits in dem elektrischen Steckverbinder 2 montiert dargestellt, wohingegen sich ein zweiter Kontaktkörper 12 in einer noch nicht montierten Position befindet.In Figure 12 a further assembly step is shown, which preferably - but not necessarily - follows the assembly step described above for establishing the mechanical connection between the coding housing 4 and the plug body 6. Contact bodies 12 are introduced into plug connector 2 in insertion direction A through corresponding recesses 11 in coding housing 4 and in plug body 6, so that the relative position between coding housing 4 and plug body 6 is fixed. The corresponding recesses 11 are already described above Figure 2 easily recognizable in a front view. In Figure 12 a first contact body 12 is shown already mounted in the electrical connector 2, whereas a second contact body 12 is in a not yet mounted position.

In Figur 13 sind alle Kontaktkörper 12 in dem elektrischen Steckverbinder 2 montiert. Dadurch, dass das Kodiergehäuse 4 und der Steckerkörper 6 durch die Verbindungseinrichtung 8 in Einsteckrichtung A bereits formschlüssig miteinander verbunden sind, kann das Schienensystem beziehungsweise die Verbindungseinrichtung 8 durch Einbringen der Kontaktkörper 12 bzw. bereits durch das Einbringen eines einzigen Kontaktkörpers 12 blockiert werden, wodurch die Position zwischen Kodiergehäuse 4 und Steckerkörper 6 in alle Raumrichtungen festgelegt ist. Grundsätzlich kann das Kodiergehäuse 4 und/oder der Steckerkörper 6 ausgebildet sein, um ein bis zehn Kontaktkörper 12, vorzugsweise zwei bis sechs Kontaktkörper 12 und ganz besonders bevorzugt vier Kontaktkörper 12 aufzunehmen.In Figure 13 all contact bodies 12 are mounted in the electrical connector 2. Because the coding housing 4 and the plug body 6 are already positively connected to one another by the connecting device 8 in the insertion direction A, the rail system or the connecting device 8 can be blocked by introducing the contact body 12 or even by introducing a single contact body 12, whereby the Position between coding housing 4 and connector body 6 is set in all spatial directions. In principle, the coding housing 4 and / or the plug body 6 can be designed to accommodate one to ten contact bodies 12, preferably two to six contact bodies 12 and very particularly preferably four contact bodies 12.

Der wenigstens eine Kontaktkörper 12 kann dadurch eingebracht werden, dass er in dem Steckerkörper 6 bzw. dessen Aufnahme 11 verpresst, verlötet, verschweißt, verschmolzen und/oder verklebt wird. Vorzugsweise wird der wenigstens eine Kontaktkörper 12 in dem Steckerkörper 6 bzw. der zugeordneten Aufnahme 11 verpresst.The at least one contact body 12 can be introduced in that it is pressed, soldered, welded, fused and / or glued into the plug body 6 or its receptacle 11. The at least one contact body 12 is preferably pressed into the plug body 6 or the associated receptacle 11.

Der Querschnitt des Kontaktkörper 12 kann einen stufigen Aufbau aufweisen, wie dargestellt, derart dass ein Anschlag ausgebildet wird, der das Einschieben des Kontaktkörpers 12 in die Aufnahme 11 des Steckerkörpers 6 begrenzt.The cross section of the contact body 12 can have a stepped structure, as shown, in such a way that a stop is formed which limits the insertion of the contact body 12 into the receptacle 11 of the plug body 6.

Vorzugsweise kann der wenigstens eine Kontaktkörper 12 als rohrförmiger Außenleiter bzw. als Kontakthülse und zur Aufnahme jeweils wenigstens eines Innenleiterteils 19 (vgl. Figur 14) ausgebildet sein. Die als Außenleiter bzw. Masseleiter ausgebildeten Kontaktkörper 12 sind im Ausführungsbeispiel mit dem Steckerkörper 6 verpresst, der vorzugsweise aus Metall, insbesondere als Zinkdruckgussteil ausgebildet ist. Hierdurch können die Außenleiter zur Abschirmung der nachfolgend noch beschriebenen Innenleiterteile 19 elektrisch mit dem Steckerkörper 6 und anschließend der elektrischen Baugruppe, beispielsweise einer Masseleitung einer Leiterplatte 5 oder einem Außenleiter eines elektrischen Kabels 14 verbunden werden.The at least one contact body 12 can preferably be used as a tubular outer conductor or as a contact sleeve and for receiving at least one inner conductor part 19 (cf. Figure 14 ) be trained. The contact bodies 12 embodied as external conductors or ground conductors are pressed in the exemplary embodiment with the plug body 6, which is preferably made of metal, in particular as a zinc die-cast part. In this way, the outer conductors for shielding the inner conductor parts 19 described below can be electrically connected to the plug body 6 and then to the electrical assembly, for example a ground line of a circuit board 5 or an outer conductor of an electrical cable 14.

In einem vorzugsweise weiteren Montageschritt kann das eines oder können die mehreren Innenleiterteile 19 in den Steckverbinder 2 eingebracht werden. Diese können vorzugsweise von der Rückseite des Steckerkörpers 6 in die als Kontakthülsen ausgebildeten Kontaktkörper 12 eingeschoben werden. Die Innenleiterteile 19 können - je nach Ausführung des Steckverbinders 2 als gerader oder winkliger Steckverbinder 2 - ebenfalls gerade oder winklig ausgebildet sein. Vorzugsweise kann zur elektrischen Isolierung zwischen den Innenleiterteilen 19 ein Dielektrikum vorgesehen sein (nicht dargestellt).In a preferably further assembly step, the one or more inner conductor parts 19 can be introduced into the plug connector 2. These can preferably be pushed from the rear of the plug body 6 into the contact bodies 12, which are designed as contact sleeves. The inner conductor parts 19 can - depending on the design of the connector 2 as a straight or angled connector 2 - also be straight or angled. A dielectric can preferably be provided for electrical insulation between the inner conductor parts 19 (not shown).

Üblicherweise wird ein derart montierter erfindungsgemäßer Steckverbinder 2 anschließend mit der elektrischen Baugruppe, vorliegend eine Leiterplatte 5, elektrisch und mechanisch verbunden. Dies ist in Figur 14 angedeutet. Dabei kann zunächst eine Masseverbindung mit der Leiterplatte 5 durch Verlöten der Kontaktfüße 20 des Steckerkörpers 6 hergestellt werden, wodurch der Steckerkörper 6 die aufgenommenen Innenleiterteile 19 elektrisch abzuschirmen vermag und hierdurch ggf. auch die als Außenleiter ausgebildeten Kontaktkörper 12 kontaktiert. Ferner können die Innenleiterteile 19 mit entsprechenden Leiterbahnen (nicht dargestellt) der Leiterplatte 5 verbunden (z. B. verlötet) werden.Typically, a plug connector 2 according to the invention mounted in this way is then electrically and mechanically connected to the electrical assembly, in this case a printed circuit board 5. This is in Figure 14 indicated. A ground connection with the circuit board 5 can first be established by soldering the contact feet 20 of the connector body 6, whereby the connector body 6 is able to electrically shield the internal conductor parts 19 and thereby possibly also contacts the contact bodies 12 designed as external conductors. Furthermore, the inner conductor parts 19 can be connected (for example soldered) to corresponding conductor tracks (not shown) of the circuit board 5.
