Definitions
- the invention relates to a plug connector of an electrical plug connection which has the plug connector and a mating plug connector assigned to the plug connector as a counterpart, to which the plug connector can be plugged in a plugging direction.
- the invention also relates to an electrical plug connection which has a plug connector of the type explained above and a mating plug connector assigned to the plug connector as a counterpart, to which the plug connector can be plugged in a plugging direction.
- the invention relates to the field of electrical plug connections, in particular multi-pole electrical plug connections. It is known e.g. B. from the DE44 20 984 C2 that such electrical connectors can be designed to be codable, with coding elements being able to be attached in profile grooves of the connector.
- the invention is based on the object of further improving such electrical plug connections and their plug connectors with regard to universal applicability and flexibility for the user.
- the connector according to the invention gives the user the option of equipping the connector with one or more functional elements as required, in a manner that is much more flexible than in the prior art.
- the connector can thus be adapted to a much greater extent according to the customer's wishes or the wishes of the end user in individual cases, without this being associated with great effort.
- there are advantages in terms of manufacturing technology because uniform plug-in connectors are provided for a large number of applications, which can be adapted by the customer or end user by inserting one or more functional elements in the first and second receiving grooves.
- the first receiving groove and / or the second receiving groove can in particular be designed as a universal receiving groove or as a universal fixing element for fixing a wide variety of functional elements that can be selected by the user.
- the first and the second receiving groove By arranging the first and the second receiving groove in the area of the first and second housing walls, which are arranged at an angle to one another, the different functional elements can accordingly be fixed in this area of the housing, thus in the vicinity of the plug face of the connector.
- the plug face of a plug connector is the area that points in the plugging direction to the mating connector and is plugged together with the mating connector.
- the functional elements can be designed for different functions of the connector, for example as a coding element for coding the connector, as a locking element for locking the connector with the mating connector to avoid unintentional loosening, as labeling elements or as other functional elements. Coding in this context means that a certain combination of coding elements is attached to the connector, which is assigned to a corresponding counter-coding on the mating connector, so that due to this coding, the connector can only be plugged into a corresponding counter-coded mating connector.
- Another advantage of the invention is that the arrangement and position of the functional elements fastened in the first and / or the second receiving groove is not permanently fixed, but can also be changed later if necessary. So z. B. a recoding of the connector or a change in the locking type can be carried out later.
- the second housing wall has the property that it points in the plug-in direction so that it is visible when the plug connector is viewed from the plug-in face.
- the angle between the first housing wall and the second housing wall can e.g. be a right angle. Alternatively, other angles can also be implemented, for example in the range from 45 ° to 135 °. Accordingly, in such cases the second housing wall would be arranged at an angle to the first housing wall.
- the connector has, for example, several first receiving grooves arranged next to one another in the direction of arrangement and / or several second receiving grooves arranged next to one another in the direction of arrangement
- functional elements can also be fastened across grooves, for example in two or more first receiving grooves or in two or more second receiving grooves.
- they can also be fastened in a combined manner in a first and a second receiving groove, in particular if the first and the second receiving groove are aligned with one another or are at least arranged close to one another.
- a plurality of functional elements can also be inserted into a first and / or second receiving groove.
- two functional elements can also be used there per pair of first and second receiving grooves, e.g. a functional element in the first receiving groove and a functional element in the second receiving groove. In this way, the functional elements can support and secure one another.
- the first receiving groove intersects the plane of the outer surface of the second housing wall.
- the first receiving groove thus extends at least a little way into the material of the second housing wall. This allows a particularly reliable fastening of functional elements in the first receiving groove.
- the second receiving groove intersects the plane of the outer surface of the first housing wall.
- the material of the second receiving groove thus extends at least a little way into the material of the first housing wall. This allows functional elements to be fastened particularly reliably in the second receiving groove.
- the central axis of a first receiving groove is skewed to a central axis of a second receiving groove. Accordingly, these central axes do not intersect. This applies in particular to first and second receiving grooves that are assigned to one another.
- the first receiving groove is connected to the second receiving groove in a cut area or is formed separately from the second receiving groove. If the first receiving groove is formed separately from the second receiving groove, then for example a separating web between the first and the second receiving groove can be formed by the material of the first housing wall and / or the second housing wall. If the first receiving groove has an area of intersection with the second receiving groove, the first receiving groove thus merges into the second receiving groove. This creates an angular installation space in the corner area, ie in the intersection area of the first and the second receiving groove, which provides further advantageous fastening options for functional elements.
- the advantageous possibility is created to mount functional elements there from two directions, each of which can use the connected installation space (angular installation space) and thus part of the other adjacent receiving groove.
- the fixation of a functional element that is mounted in the first receiving groove extending in the plug-in direction extend through the adjacent space to the outside and so z. B. enable an external coding element that is fixed on the inside and can be mounted in the plug-in direction.
- Functional elements which extend with their fastening unit into the first receiving groove can in particular be advantageously fastened by the second receiving groove.
- the inclusion of functional elements such as locking units or latching lugs is particularly advantageous here.
- the first receiving groove and / or the second receiving groove has a profile with at least one undercut. This allows functional elements to be reliably fastened in the first and / or the second receiving groove.
- the profile can e.g. B. be a dovetail profile or a T-shaped profile.
- the first receiving groove is spatially assigned to a plug contact of the connector.
- This can e.g. B. be realized in that a respective first receiving groove is arranged in the longitudinal direction in alignment with an electrical plug contact to which the first receiving groove is assigned. This results in a good utilization of the installation space for the attachment of a large number of functional elements to the connector housing and thus a large number of possible combinations of the functional elements.
- the second receiving groove is spatially assigned to a plug contact of the connector.
- This can e.g. B. be realized in that a respective second receiving groove is arranged in the longitudinal direction in alignment with an electrical plug contact to which the second receiving groove is assigned. This results in a good utilization of the installation space for attaching a large number of functional elements to the housing of the plug connector and thus a large number of possible combinations of the functional elements.
- the housing of the plug connector can have conductor entry openings for one, several or all plug contacts, through which electrical conductors (cables) to be connected to the plug contact can be guided through the housing to the plug contact.
- the conductor entry openings are arranged distributed on one housing side or on several housing sides that are not the side with the mating face of the connector.
- one, several or all of the plug contacts each have a fastening element for fastening an electrical conductor to the plug contact, at least part of the fastening element being arranged in a socket-shaped section of the housing, which extends towards the plug face through the second housing wall is limited.
- the fastening element can be, for example, a screw fastening element or a spring-force clamping fastening element, for example in the form of a cage clamp spring.
- the fastening elements of the plug connector can be designed the same or different, for example according to one of the principles mentioned above.
- the first receiving groove and / or the second receiving groove are designed as a universal fixing element for fixing different functional elements to be selected by the user.
- a first receiving groove can be spatially assigned to a second receiving groove, e.g. B. in that the first and the second receiving groove, which are assigned to one another, are arranged close to one another.
- these can each have the same profile cross section or different profile cross sections, for example different widths or different depths of the grooves.
- respective central planes of the first and second receiving grooves running in the longitudinal direction of the first and second receiving grooves are aligned coplanar or parallel to one another.
- a first receiving groove can be spatially assigned to a second receiving groove.
- the longitudinal direction of the first receiving groove is understood to mean the direction in which the first receiving groove extends away from the second housing wall.
- the longitudinal direction of the second receiving groove is understood to mean that direction in which the second receiving groove extends away from the first housing wall.
- the middle plane of a respective receiving groove is understood to be a plane which runs perpendicular to the direction of arrangement and runs centrally through the respective receiving groove in its longitudinal direction. This allows additional advantageous fastening options for the functional elements on the first and second receiving grooves.
- the second receiving groove is arranged in alignment with the first receiving groove.
- a first receiving groove can be spatially assigned to a second receiving groove. This allows further advantageous fastening options for the functional elements on the first and second receiving grooves.
- the connector is composed in several parts from individual connector segments, each connector segment having its own housing and the housing of the connector is at least partially formed from the assembled housings of the connector segments.
- the connector can have connector segments with their own housing, each of which has a first and a second receiving groove, as explained above.
- the connector can also have connector segments with their own housing which does not have any such receiving grooves or has only a first or only a second receiving groove of the type described above.
- the housing of the plug connector can be formed variably as required by the user with different configurations of first and second receiving grooves.
- the connector can be formed exclusively from connector segments, each with a first and a second receiving groove. This results in a maximum selection for the attachment of functional elements on the connector for the user.
- the invention also relates to an electrical plug connection which has a plug connector of the type explained above and a mating plug connector assigned to the plug connector as a counterpart, to which the plug connector can be or is plugged in in one plugging direction.
- a plug connector of the type explained above and a mating plug connector assigned to the plug connector as a counterpart, to which the plug connector can be or is plugged in in one plugging direction.
- the mating connector can be advantageously developed in a comparable manner to that described above for the connector.
- all of the features explained above for the connector can thus be implemented in the same way, with the mating connector having the third housing wall corresponding to the first housing wall of the connector and the fourth housing wall corresponding to the second housing wall of the connector.
- the third receiving groove corresponds to the first receiving groove of the plug connector and the fourth receiving groove corresponds to the second receiving groove of the plug connector.
- the invention also relates to a set comprising at least one connector of the type explained above and at least one functional element which has at least one fastening area that can be fastened in the first receiving groove and / or the second receiving groove.
- the indefinite term “a” is not to be understood as a numerical word. So if e.g. If a component is mentioned, this is to be interpreted in the sense of "at least one component”. As far as angles are given in degrees, these refer to a circle of 360 degrees (360 °).
- the Figure 1 shows a connector 1 which has a housing 2.
- the connector 1 is composed, for example, of several individual connector segments, each of which has its own housing 5.
- the connector segments or their housing 5 are lined up next to one another in a direction A and attached to one another, for. B. by locking with each other.
- the row of individual housings 5 is closed on one side by an end plate 6.
- the connector 1 can also be designed with a continuous housing 2.
- the end plate 6 is an optional component that is not required in all cases.
- the direction of arrangement A defines in particular the arrangement in which the electrical plug-in contacts of the plug connector 1, which are arranged in the housing 2, are arranged next to one another.
- the housing 2 has a step 3 which points in the plug-in direction S.
- the gradation 3 is formed by adjoining housing walls, namely a first housing wall 10, which is arranged parallel to a plane spanned by the plug-in direction S and the row direction A, and a second housing wall 20, which adjoins the first housing wall 10.
- the second housing wall 20 also points in the insertion direction S and is arranged at an angle to the first housing wall 10, for. B. at a right angle.
- the first housing wall 10 is formed by respective individual first housing wall segments of the individual housings 5
- the second housing wall 20 is formed by individual second housing wall segments of the housing 5.
- the plug connector 1 or its housing 2 ends in the plugging direction S with the plug face 4. From the side of the plug face 4, respective contact openings 50 lead to the electrical plug contacts of the plug connector 1 arranged in the housing 2.
- the housing 2 has first receiving grooves 11 in the first housing wall 10 and second receiving grooves 21 in the second housing wall 20 for fastening functional elements.
- the first receiving grooves 11 run with their longitudinal direction in the plugging direction S.
- the second receiving grooves 21 in this exemplary embodiment run with their longitudinal direction perpendicular to the plane spanned by the plugging direction S and the rowing direction A.
- the Figure 2 shows, to illustrate the first and the second receiving grooves 11, 21, an enlarged section from FIG Figure 1 . It can be seen that the respective first receiving groove 11 merges into the respective associated second receiving groove 21. This creates a cutting area 30 and thus an angular receiving space.
- the Figure 3 shows an even greater enlargement of a section in which the arrangement of a first receiving groove 11 and a second receiving groove 21 associated therewith can be seen.
- the cut area 30 is again between the receiving grooves 11, 21 can be seen.
- the second receiving groove 21 can have a constriction point 22 at which the profile cross section of the second receiving groove 21 is reduced. This creates a stop by which the depth of insertion of a functional element inserted into the second receiving groove 21 is limited.
- the first receiving groove 11 can be designed with such a constriction in a manner comparable to that of the second receiving groove 21.
- an undercut is provided on the opposite surface of the constriction 22 that forms the stop. This undercut can form a latching element designed as a latching edge for a functional element 8 inserted in the receiving groove 1, wherein the functional element 8 can have a counter-latching element corresponding to the latching element of the guide groove 21.
- an electrical plug contact 72 arranged in the housing 2 can be seen. Furthermore, elements of a contact insert can be seen which serve to electrically and mechanically connect an electrical line, which can be inserted through a conductor insertion opening 51 of the housing 2, to the plug contact 72.
- the contact insert can in particular have a fastening element 7 with which the electrical conductor can be fastened to the plug contact 72.
- An example is in the Figure 4 the design of the fastening element 7 is shown as a spring-loaded terminal connection.
- the spring-loaded terminal connection has a clamping spring 70, which is designed here, for example, as a cage tension spring, and a busbar 71.
- the busbar 71 is connected to the plug contact 72 in an electrically conductive manner.
- An electrical conductor can be clamped onto the busbar 71 by means of the clamping spring 70.
- the Figure 5 shows the connector according to Figure 1 , with two differently designed functional elements 8 being attached to the connector 1.
- the functional elements 8 are attached to the plug connector 1 in that they are attached to the first receiving groove 11 and / or to the second receiving groove 21 with correspondingly shaped fixing elements.
- the functional element 8, which can be seen further ahead, is a first latching element 81 for latching the plug connector 1 with a mating plug connector.
- the functional element 8, which can be seen further to the rear, is a second latching element 80 with a manual actuator, which is also used for latching can be made with a mating connector and can be released again via the manual actuator.
- first latching element 81 The further structure of the first latching element 81 is described with reference to the sectional illustration 6 explained below, with reference to the sectional illustration in FIG Figure 7 the structure of the second latching element 80.
- the Figures 6 and 7th correspond to the representation of Figure 4 , wherein in addition to the respective functional elements 8, a mating connector 9 is also shown, with which the connector 1 is plugged together.
- the mating connector 9 also has electrical plug contacts 91 and one or more latching elements 90.
- the first latching element 81 has a second fastening section 83 fastened in the second receiving groove 21 and a first fastening section 84 fastened in the first receiving groove 11.
- the fastening sections 83, 84 can be formed separately or, as shown, connected.
- the first latching element 81 is inserted into the second receiving groove 21 with the first fastening section 83 in a direction perpendicular to the plane formed by the leaning direction A and the plugging direction S.
- the second receiving groove 21 and the first fastening section 83 form a form-fitting connection, for example in the manner of a dovetail guide.
- the second fastening section 84 of the first latching element 81 forms a support for the first latching element 81 in the first receiving groove 11 as well as a support and / or support for the latching element or elements 90 of the mating connector 9.
- the first latching element 81 has a plug-in direction S protruding latching arm 82 which, together with the latching element 90, produces a latching between the connector 1 and the mating connector 9. As a result of the latching, the connector 1 cannot easily become detached from the mating connector 9.
- the recognizable fixation of the first latching element 81 via the angled fastening areas 83, 84 causes a particularly reliable fixation on the connector, since this provides a kind of support geometry that absorbs the torques acting on the receiving grooves 11, 21 when there is tensile stress and so The functional element 8 is prevented from loosening in the sense of being unscrewed.
- the first latching element 81 is also securely held in the receiving grooves 11, 21, in particular the first latching element 81 cannot slide out of the second receiving groove 21 against the insertion direction.
- the Figure 7 again shows the connector 1, which is plugged together with the mating connector 9.
- the second latching element 80 can be seen, which, analogously to the first latching element 81 described above, in turn has the fastening areas 83, 84, which can be designed identically or at least similarly to the first latching element 81.
- the second latching element 80 also has a latching arm 82, which, with the latching element 90, latches the connector 1 to the mating connector 9.
- the second latching element 80 has a manual actuator 85 which is connected to the latching arm 82 via a connecting arm 86.
- the connecting arm 86 causes this movement to be deflected, so that the latching arm 82 is deflected upwards and is therefore no longer in engagement with the latching element 90. In this way, the connector 1 can be detached from the mating connector 9.
- a functional element 8 can only be attached to an arrangement of first receiving groove 11 and associated second receiving groove 21.
- a functional element 8 can additionally be attached to a plurality of first and second receiving grooves 11, 21.
- a functional element can also be attached to only a first receiving groove 11 or to a plurality of first receiving grooves 11, or to only a second receiving groove 21 or to a plurality of second receiving grooves 21.
- the Figure 8 shows a connector 1, with functional elements 8 of different design being fastened to the first and second receiving grooves 11, 21.
- Functional elements 8 shown by way of example are coding elements 88 with which the connector 1 can be coded.
- the coding elements 88 in turn have a second fastening region 83 fastened in the second receiving groove 21 and a second fastening region 83 with it connected first fastening region 84 fastened in the first receiving groove 11.
- the coding elements 88 are advantageously inserted into the first receiving grooves 11 with a second fastening area 84, counter to the plug-in direction S, for example with a form-fitting dovetail guide.
- the second fastening area 83 of the coding elements 88 is then supported in the second receiving grooves 21 in the assembly position.
- the coding elements 88 can rest and / or be supported on the second housing wall 20 of the housing 2 of the connector of the housing 5 of the connector segment with a surface that is set back with respect to the second fastening area 81.
- the coding elements 88 can each have coding lugs 87 projecting in the plug-in direction S, by means of which a first coding of a coding element 88 is created.
- a second coding of the coding element 88 can be created by the length of the first fastening areas 84. If the first fastening areas 84 are made relatively long, e.g. B.
- the length of the coding nose 87 can be designed differently , ie with a long coding nose 87, a different coding is achieved than with a correspondingly shorter coding nose or if the coding nose 87 is omitted.
- the first and / or the second receiving groove 11, 21 can also be extended even further in this cutting area 30, so that it extends beyond the groove base of the other associated receiving groove.
- a depression is formed in the groove base of the respective receiving groove running perpendicular thereto.
- Such a recess can be used to receive one end of a functional element. This end of the functional element can be received in a latching manner (latching edges) and / or clamping in the respective recess. On In this way, extraction forces and / or torques acting on the functional element can be absorbed and neutralized.
- the first receiving groove 11 extends with a first extension section 13 beyond the groove base of the second receiving groove 21, that is, the cutting area 30 is somewhat elongated counter to the insertion direction S and protrudes further into the material of the housing 2. In this way, a recess is formed in the groove base of the second receiving groove 21.
- FIGS 11 and 12 show an embodiment in which the second receiving groove 21 is designed to be extended with a second extension section 23, that is to say extends beyond the groove base of the first receiving groove 11 in the cut area 30. In this way, a recess is formed in the groove bottom of the first receiving groove 11.
- the Figures 13 and 14 show an embodiment in which the respectively elongated first and second receiving grooves 11, 12, as they are based on FIG Figures 9 to 12 have been described, are realized in combination with one another.
- the first receiving groove 11 thus extends beyond the groove base of the second receiving groove 21 in the intersection area 30 with the first extension section 13.
- the second receiving groove 21 extends in the intersection area 30 with the second extension section 23 beyond the groove base of the first receiving groove 11. In this way, depressions are formed both in the groove base of the first receiving groove 11 and in the groove base of the second receiving groove 21.

Description
Die Erfindung betrifft einen Steckverbinder einer elektrischen Steckverbindung, die den Steckverbinder und einen dem Steckverbinder als Gegenstück zugeordneten Gegensteckverbinder aufweist, an den der Steckverbinder in einer Steckrichtung ansteckbar ist. Die Erfindung betrifft außerdem eine elektrische Steckverbindung, die einen Steckverbinder der zuvor erläuterten Art und einen dem Steckverbinder als Gegenstück zugeordneten Gegensteckverbinder aufweist, an den der Steckverbinder in einer Steckrichtung ansteckbar ist.The invention relates to a plug connector of an electrical plug connection which has the plug connector and a mating plug connector assigned to the plug connector as a counterpart, to which the plug connector can be plugged in a plugging direction. The invention also relates to an electrical plug connection which has a plug connector of the type explained above and a mating plug connector assigned to the plug connector as a counterpart, to which the plug connector can be plugged in a plugging direction.
Allgemein betrifft die Erfindung das Gebiet der elektrischen Steckverbindungen, insbesondere der mehrpoligen elektrischen Steckverbindungen. Es ist bekannt, z. B. aus der
Der Erfindung liegt die Aufgabe zugrunde, solche elektrischen Steckverbindungen und deren Steckverbinder im Hinblick auf die universelle Anwendbarkeit und Flexibilität für den Anwender weiter zu verbessern.The invention is based on the object of further improving such electrical plug connections and their plug connectors with regard to universal applicability and flexibility for the user.
Diese Aufgabe wird gelöst durch einen Steckverbinder einer elektrischen Steckverbindung, die den Steckverbinder und einen dem Steckverbinder als Gegenstück zugeordneten Gegensteckverbinder aufweist, an den der Steckverbinder in einer Steckrichtung ansteckbar ist, wobei der Steckverbinder ein Gehäuse und mehrere zumindest teilweise in dem Gehäuse angeordnete elektrische Steckkontakte aufweist, die in einer Anreihrichtung nebeneinander angeordnet sind, wobei eine erste Gehäusewand des Gehäuses, die parallel zu einer durch die Steckrichtung und die Anreihrichtung aufgespannten Ebene angeordnet ist, an eine zweite Gehäusewand des Gehäuses angrenzt, die in Steckrichtung weist und abgewinkelt zur ersten Gehäusewand angeordnet ist, mit folgenden Merkmalen:
- a) die erste Gehäusewand weist wenigstens eine mit ihrer Längsrichtung in Steckrichtung verlaufende erste Aufnahmenut zur Aufnahme eines Funktionselements auf,
- b) die zweite Gehäusewand weist wenigstens eine zweite Aufnahmenut zur Aufnahme eines Funktionselements auf.
- a) the first housing wall has at least one first receiving groove, running with its longitudinal direction in the insertion direction, for receiving a functional element,
- b) the second housing wall has at least one second receiving groove for receiving a functional element.
Dies erlaubt es, dass Funktionselemente aus verschiedenen Richtungen an dem Steckverbinder angebracht werden. Zudem ist eine Erhöhung der Polarität der Kodierung des Steckverbinders möglich.This allows functional elements to be attached to the connector from different directions. It is also possible to increase the polarity of the connector coding.
Durch den erfindungsgemäßen Steckverbinder wird dem Anwender die Möglichkeit gegeben, in im Vergleich zum Stand der Technik wesentlich flexiblerer Weise den Steckverbinder je nach Bedarf mit einem oder mehreren Funktionselementen auszustatten. Der Steckverbinder kann somit in wesentlich stärkerem Maß nach den Kundenwünschen oder den Wünschen des Endanwenders im Einzelfall angepasst werden, ohne dass dies mit großem Aufwand verbunden ist. Zudem ergeben sich fertigungstechnische Vorteile, weil einheitliche Steckverbinder für eine Vielzahl von Anwendungen bereitgestellt werden, die vom Kunden oder Endanwender durch Einsetzen eines oder mehrerer Funktionselemente in den ersten und zweiten Aufnahmenuten anpassbar sind.The connector according to the invention gives the user the option of equipping the connector with one or more functional elements as required, in a manner that is much more flexible than in the prior art. The connector can thus be adapted to a much greater extent according to the customer's wishes or the wishes of the end user in individual cases, without this being associated with great effort. In addition, there are advantages in terms of manufacturing technology because uniform plug-in connectors are provided for a large number of applications, which can be adapted by the customer or end user by inserting one or more functional elements in the first and second receiving grooves.
Die erste Aufnahmenut und/oder die zweite Aufnahmenut kann dabei insbesondere als universelle Aufnahmenut bzw. als universelles Fixierelement zur Fixierung unterschiedlichster Funktionselemente, die vom Anwender ausgewählt werden können, ausgebildet sein. Durch die Anordnung der ersten und der zweiten Aufnahmenut im Bereich der winklig zueinander angeordneten ersten und zweiten Gehäusewand können dementsprechend die unterschiedlichen Funktionselemente in diesem Bereich des Gehäuses fixiert werden, somit in der Nähe des Steckgesichts des Steckverbinders. Als Steckgesicht eines Steckverbinders bezeichnet man denjenigen Bereich, der in Steckrichtung zum Gegensteckverbinder weist und mit dem Gegensteckverbinder zusammengesteckt wird.The first receiving groove and / or the second receiving groove can in particular be designed as a universal receiving groove or as a universal fixing element for fixing a wide variety of functional elements that can be selected by the user. By arranging the first and the second receiving groove in the area of the first and second housing walls, which are arranged at an angle to one another, the different functional elements can accordingly be fixed in this area of the housing, thus in the vicinity of the plug face of the connector. The plug face of a plug connector is the area that points in the plugging direction to the mating connector and is plugged together with the mating connector.
Die Funktionselemente können für unterschiedliche Funktionen des Steckverbinders ausgebildet sein, beispielsweise als Kodierelement zur Kodierung der Steckverbindung, als Verriegelungselement zur Verriegelung des Steckverbinders mit dem Gegensteckverbinder, um ein unbeabsichtigtes Lösen zu vermeiden, als Beschriftungselemente oder als sonstiges Funktionselement. Kodierung bedeutet in diesem Zusammenhang, dass eine bestimmte Kombination von Kodierelementen am Steckverbinder befestigt wird, die einer entsprechenden Gegenkodierung am Gegensteckverbinder zugeordnet ist, sodass aufgrund dieser Kodierung der Steckverbinder nur an einen entsprechend gegenkodierten Gegensteckverbinder angesteckt werden kann.The functional elements can be designed for different functions of the connector, for example as a coding element for coding the connector, as a locking element for locking the connector with the mating connector to avoid unintentional loosening, as labeling elements or as other functional elements. Coding in this context means that a certain combination of coding elements is attached to the connector, which is assigned to a corresponding counter-coding on the mating connector, so that due to this coding, the connector can only be plugged into a corresponding counter-coded mating connector.
Ein weiterer Vorteil der Erfindung besteht darin, dass die Anordnung und Position von in der ersten und/oder der zweiten Aufnahmenut befestigten Funktionselementen nicht dauerhaft festgelegt ist, sondern auch später noch bei Bedarf geändert werden kann. So kann z. B. eine Umkodierung des Steckverbinders oder eine Änderung der Verriegelungsart nachträglich durchgeführt werden.Another advantage of the invention is that the arrangement and position of the functional elements fastened in the first and / or the second receiving groove is not permanently fixed, but can also be changed later if necessary. So z. B. a recoding of the connector or a change in the locking type can be carried out later.
Die zweite Gehäusewand hat wie erwähnt die Eigenschaft, dass sie in Steckrichtung weist, sodass sie sichtbar ist, wenn der Steckverbinder von dem Steckgesicht her betrachtet wird. Dabei kann der Winkel zwischen der ersten Gehäusewand und der zweiten Gehäusewand z.B. ein rechter Winkel sein. Alternativ können auch andere Winkel realisiert werden, beispielsweise im Bereich von 45° bis 135°. Dementsprechend würde in solchen Fällen die zweite Gehäusewand schräg zur ersten Gehäusewand angeordnet sein.As mentioned, the second housing wall has the property that it points in the plug-in direction so that it is visible when the plug connector is viewed from the plug-in face. The angle between the first housing wall and the second housing wall can e.g. be a right angle. Alternatively, other angles can also be implemented, for example in the range from 45 ° to 135 °. Accordingly, in such cases the second housing wall would be arranged at an angle to the first housing wall.
Wenn der Steckverbinder beispielsweise mehrere in Anreihrichtung nebeneinander angeordnete erste Aufnahmenuten und/oder mehrere in Anreihrichtung nebeneinander angeordnete zweite Aufnahmenuten aufweist, so können Funktionselemente auch nutenübergreifend befestigt werden, beispielsweise in zwei oder mehr ersten Aufnahmenuten oder in zwei oder mehr zweiten Aufnahmenuten. Je nach Ausgestaltung der Funktionselemente können diese auch kombiniert in einer ersten und einer zweiten Aufnahmenut befestigt werden, insbesondere wenn die erste und die zweite Aufnahmenut miteinander fluchten oder zumindest nahe beieinander angeordnet sind.If the connector has, for example, several first receiving grooves arranged next to one another in the direction of arrangement and / or several second receiving grooves arranged next to one another in the direction of arrangement, functional elements can also be fastened across grooves, for example in two or more first receiving grooves or in two or more second receiving grooves. Depending on the configuration of the functional elements, they can also be fastened in a combined manner in a first and a second receiving groove, in particular if the first and the second receiving groove are aligned with one another or are at least arranged close to one another.
In eine erste und/oder zweite Aufnahmenut können jeweils auch mehrere Funktionselemente eingesetzt sein. Es können beispielsweise auch pro Paar von erster und zweiter Aufnahmenut dort zwei Funktionselemente eingesetzt sein, z.B. ein Funktionselement in die erste Aufnahmenut und ein Funktionselement in die zweite Aufnahmenut. Auf diese Weise können sich die Funktionselemente gegenseitig abstützen und sichern.A plurality of functional elements can also be inserted into a first and / or second receiving groove. For example, two functional elements can also be used there per pair of first and second receiving grooves, e.g. a functional element in the first receiving groove and a functional element in the second receiving groove. In this way, the functional elements can support and secure one another.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die erste Aufnahmenut die Ebene der Außenoberfläche der zweiten Gehäusewand schneidet. Die erste Aufnahmenut erstreckt sich somit zumindest ein Stück weit in das Material der zweiten Gehäusewand hinein. Dies erlaubt eine besonders zuverlässige Befestigung von Funktionselementen in der ersten Aufnahmenut.According to an advantageous embodiment of the invention it is provided that the first receiving groove intersects the plane of the outer surface of the second housing wall. The first receiving groove thus extends at least a little way into the material of the second housing wall. This allows a particularly reliable fastening of functional elements in the first receiving groove.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die zweite Aufnahmenut die Ebene der Außenoberfläche der ersten Gehäusewand schneidet. Das Material der zweiten Aufnahmenut erstreckt sich somit zumindest ein Stück weit in das Material der ersten Gehäusewand hinein. Dies erlaubt eine besonders zuverlässige Befestigung von Funktionselementen in der zweiten Aufnahmenut.According to an advantageous embodiment of the invention, it is provided that the second receiving groove intersects the plane of the outer surface of the first housing wall. The material of the second receiving groove thus extends at least a little way into the material of the first housing wall. This allows functional elements to be fastened particularly reliably in the second receiving groove.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Mittelachse einer ersten Aufnahmenut windschief zu einer Mittelachse einer zweiten Aufnahmenut verläuft. Dementsprechend schneiden sich diese Mittelachsen nicht. Dies gilt insbesondere für einander zugeordnete erste und zweite Aufnahmenuten.According to an advantageous embodiment of the invention it is provided that the central axis of a first receiving groove is skewed to a central axis of a second receiving groove. Accordingly, these central axes do not intersect. This applies in particular to first and second receiving grooves that are assigned to one another.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die erste Aufnahmenut in einem Schnittbereich mit der zweiten Aufnahmenut verbunden ist oder von der zweiten Aufnahmenut getrennt ausgebildet ist. Ist die erste Aufnahmenut von der zweiten Aufnahmenut getrennt ausgebildet, so kann beispielsweise ein Trennsteg zwischen der ersten und der zweiten Aufnahmenut durch das Material der ersten Gehäusewand und/oder der zweiten Gehäusewand gebildet sein. Weist die erste Aufnahmenut einen Schnittbereich mit der zweiten Aufnahmenut auf, so geht somit die erste Aufnahmenut in die zweite Aufnahmenut über. Hierdurch wird ein winkelförmiger Bauraum im Eckbereich geschaffen, d. h. im Schnittbereich der ersten und der zweiten Aufnahmenut, der weitere vorteilhafte Befestigungsmöglichkeiten für Funktionselemente bereitstellt.According to an advantageous embodiment of the invention, it is provided that the first receiving groove is connected to the second receiving groove in a cut area or is formed separately from the second receiving groove. If the first receiving groove is formed separately from the second receiving groove, then for example a separating web between the first and the second receiving groove can be formed by the material of the first housing wall and / or the second housing wall. If the first receiving groove has an area of intersection with the second receiving groove, the first receiving groove thus merges into the second receiving groove. This creates an angular installation space in the corner area, ie in the intersection area of the first and the second receiving groove, which provides further advantageous fastening options for functional elements.
Durch die Verbindung der ersten Aufnahmenut mit der zweiten Aufnahmenut wird die vorteilhafte Möglichkeit geschaffen, Funktionselemente aus zwei Richtungen dort zu montieren, die jeweils den verbundenen Bauraum (winkelförmiger Bauraum) und damit einen Teil der jeweils angrenzenden anderen Aufnahmenut nutzen kann. Durch die Verbindung der ersten Aufnahmenut mit der zweiten Aufnahmenut kann sich z. B. die Fixierung eines Funktionselements, das in der in Steckrichtung verlaufenden ersten Aufnahmenut montiert ist, durch den angrenzenden Bauraum nach Außen erstrecken und so z. B. ein außenliegendes Kodierelement ermöglichen, dass dabei innen liegend fixiert ist und in Steckrichtung montiert werden kann.By connecting the first receiving groove to the second receiving groove, the advantageous possibility is created to mount functional elements there from two directions, each of which can use the connected installation space (angular installation space) and thus part of the other adjacent receiving groove. By connecting the first receiving groove to the second receiving groove, z. B. the fixation of a functional element that is mounted in the first receiving groove extending in the plug-in direction, extend through the adjacent space to the outside and so z. B. enable an external coding element that is fixed on the inside and can be mounted in the plug-in direction.
Durch die zweite Aufnahmenut können insbesondere Funktionselemente vorteilhaft befestigt werden, die sich mit ihrer Befestigungseinheit bis in die erste Aufnahmenut hinein erstrecken. Hierbei ist insbesondere die Aufnahme von Funktionselementen wie Verriegelungseinheiten oder Rastnasen besonders vorteilhaft. Mit Hilfe einer Stützgeometrie an einem Funktionselement ist es dann möglich, die auf die zweite Aufnahmenut einwirkenden Drehmomente bei Zugbeanspruchung abzufangen, indem die Stützgeometrie unter das Gehäuse des Gegensteckverbinders greift und so ein Herausdrehen des Funktionselements verhindert.Functional elements which extend with their fastening unit into the first receiving groove can in particular be advantageously fastened by the second receiving groove. The inclusion of functional elements such as locking units or latching lugs is particularly advantageous here. With the help of a support geometry on a functional element, it is then possible to absorb the torques acting on the second receiving groove when there is tensile stress, in that the support geometry engages under the housing of the mating connector and thus prevents the functional element from unscrewing.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die erste Aufnahmenut und/oder die zweite Aufnahmenut ein Profil mit wenigstens einem Hinterschnitt aufweist. Dies erlaubt eine zuverlässige Befestigung von Funktionselementen in der ersten und/oder der zweiten Aufnahmenut. Das Profil kann z. B. ein Schwalbenschwanzprofil oder ein T-förmiges Profil sein.According to an advantageous embodiment of the invention it is provided that the first receiving groove and / or the second receiving groove has a profile with at least one undercut. This allows functional elements to be reliably fastened in the first and / or the second receiving groove. The profile can e.g. B. be a dovetail profile or a T-shaped profile.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass für eine, mehrere oder alle ersten Aufnahmenuten gilt, dass die erste Aufnahmenut jeweils einem Steckkontakt des Steckverbinders räumlich zugeordnet sind. Dies kann z. B. dadurch realisiert sein, dass eine jeweilige erste Aufnahmenut in Längsrichtung fluchtend zu einem elektrischen Steckkontakt angeordnet ist, dem die erste Aufnahmenut zugeordnet ist. Auf diese Weise ergibt sich eine gute Bauraumausnutzung für die Anbringung einer Vielzahl von Funktionselemente am Gehäuse des Steckverbinders und damit eine Vielzahl von Kombinationsmöglichkeiten der Funktionselemente.According to an advantageous embodiment of the invention, it is provided that for one, several or all of the first receiving grooves, the first receiving groove is spatially assigned to a plug contact of the connector. This can e.g. B. be realized in that a respective first receiving groove is arranged in the longitudinal direction in alignment with an electrical plug contact to which the first receiving groove is assigned. This results in a good utilization of the installation space for the attachment of a large number of functional elements to the connector housing and thus a large number of possible combinations of the functional elements.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass für eine, mehrere oder alle zweiten Aufnahmenuten gilt, dass die zweite Aufnahmenut jeweils einem Steckkontakt des Steckverbinders räumlich zugeordnet sind. Dies kann z. B. dadurch realisiert sein, dass eine jeweilige zweite Aufnahmenut in Längsrichtung fluchtend zu einem elektrischen Steckkontakt, dem die zweite Aufnahmenut zugeordnet ist, angeordnet ist. Auf diese Weise ergibt sich eine gute Bauraumausnutzung für die Anbringung einer Vielzahl von Funktionselemente am Gehäuse des Steckverbinders und damit eine Vielzahl von Kombinationsmöglichkeiten der Funktionselemente.According to an advantageous embodiment of the invention, it is provided that for one, several or all of the second receiving grooves, the second receiving groove is spatially assigned to a plug contact of the connector. This can e.g. B. be realized in that a respective second receiving groove is arranged in the longitudinal direction in alignment with an electrical plug contact to which the second receiving groove is assigned. This results in a good utilization of the installation space for attaching a large number of functional elements to the housing of the plug connector and thus a large number of possible combinations of the functional elements.
Das Gehäuse des Steckverbinders kann für einen, mehrere oder alle Steckkontakte Leitereinführungsöffnungen aufweisen, durch die am Steckkontakt anzuschließende elektrische Leiter (Kabel) durch das Gehäuse zu dem Steckkontakt geführt werden können. Es kann jeweils eine Leitereinführungsöffnung für einen jeweiligen Stecckontakt vorhanden sein, oder eine kombinierte Leitereinführungsöffnung für mehrere Steckkontakte, auch in Kombination mit Einzel-Leitereinführungsöffnungen. Die Leitereinführungsöffnungen sind an einer Gehäuseseite oder an mehreren Gehäuseseiten verteilt angeordnet, die nicht die Seite mit dem Steckgesicht des Steckverbinders sind.The housing of the plug connector can have conductor entry openings for one, several or all plug contacts, through which electrical conductors (cables) to be connected to the plug contact can be guided through the housing to the plug contact. There can be a conductor entry opening for a respective plug contact, or a combined conductor entry opening for several plug contacts, also in combination with individual conductor entry openings. The conductor entry openings are arranged distributed on one housing side or on several housing sides that are not the side with the mating face of the connector.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass einer, mehrere oder alle Steckkontakte jeweils ein Befestigungselement zur Befestigung eines elektrischen Leiters an dem Steckkontakt aufweisen, wobei zumindest ein Teil des Befestigungselements in einem sockelförmigen Abschnitt des Gehäuses angeordnet ist, der zum Steckgesicht hin durch die zweite Gehäusewand begrenzt ist. Auf diese Weise kann eine gute Raumusnutzung des Gehäuses des Steckverbinders erreicht werden. Das Befestigungselement kann beispielsweise ein Schraubbefestigungselement oder ein Federkraftklemmbefestigungselement sein, beispielsweise in Form einer Käfigzugfeder. Die Befestigungselemente des Steckverbinders können dabei gleich oder unterschiedlich ausgebildet sein, beispielsweise nach einem der zuvor genannten Prinzipien.According to an advantageous embodiment of the invention it is provided that one, several or all of the plug contacts each have a fastening element for fastening an electrical conductor to the plug contact, at least part of the fastening element being arranged in a socket-shaped section of the housing, which extends towards the plug face through the second housing wall is limited. In this way, a good use of space of the connector housing can be achieved. The fastening element can be, for example, a screw fastening element or a spring-force clamping fastening element, for example in the form of a cage clamp spring. The fastening elements of the plug connector can be designed the same or different, for example according to one of the principles mentioned above.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die erste Aufnahmenut und/oder die zweite Aufnahmenut als universelles Fixierelement zur Fixierung vom Anwender auszuwählender, unterschiedlicher Funktionselemente ausgebildet sind.According to an advantageous embodiment of the invention, it is provided that the first receiving groove and / or the second receiving groove are designed as a universal fixing element for fixing different functional elements to be selected by the user.
Es kann jeweils eine erste Aufnahmenut einer zweiten Aufnahmenut räumlich zugeordnet sein, z. B. dadurch, dass die erste und die zweite Aufnahmenut, die einander zugeordnet sind, nah beieinander angeordnet sind. Bei solchen einander zugeordneten ersten und zweiten Aufnahmenuten können diese jeweils den gleichen Profilquerschnitt oder unterschiedliche Profilquerschnitte aufweisen, beispielsweise unterschiedliche Breiten oder unterschiedliche Tiefen der Nuten.In each case a first receiving groove can be spatially assigned to a second receiving groove, e.g. B. in that the first and the second receiving groove, which are assigned to one another, are arranged close to one another. In the case of such mutually associated first and second receiving grooves, these can each have the same profile cross section or different profile cross sections, for example different widths or different depths of the grooves.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass jeweilige in Längsrichtung der ersten und der zweiten Aufnahmenut verlaufende Mittelebenen der ersten und der zweiten Aufnahmenut koplanar oder parallel zueinander ausgerichtet sind. Hierdurch kann eine erste Aufnahmenut einer zweiten Aufnahmenut räumlich zugeordnet sein. Als Längsrichtung der ersten Aufnahmenut wird dabei die Richtung verstanden, mit der sich die erste Aufnahmenut von der zweiten Gehäusewand fort erstreckt. Als Längsrichtung der zweiten Aufnahmenut wird dabei diejenige Richtung verstanden, mit der sich die zweite Aufnahmenut von der ersten Gehäusewand fort erstreckt. Als Mittelebene einer jeweiligen Aufnahmenut wird eine Ebene verstanden, die senkrecht zur Anreihrichtung verläuft und mittig durch die jeweilige Aufnahmenut in deren Längsrichtung verläuft. Dies erlaubt zusätzliche vorteilhafte Befestigungsmöglichkeiten der Funktionselemente an der ersten und zweiten Aufnahmenut.According to an advantageous embodiment of the invention, it is provided that respective central planes of the first and second receiving grooves running in the longitudinal direction of the first and second receiving grooves are aligned coplanar or parallel to one another. As a result, a first receiving groove can be spatially assigned to a second receiving groove. The longitudinal direction of the first receiving groove is understood to mean the direction in which the first receiving groove extends away from the second housing wall. The longitudinal direction of the second receiving groove is understood to mean that direction in which the second receiving groove extends away from the first housing wall. The middle plane of a respective receiving groove is understood to be a plane which runs perpendicular to the direction of arrangement and runs centrally through the respective receiving groove in its longitudinal direction. This allows additional advantageous fastening options for the functional elements on the first and second receiving grooves.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die zweite Aufnahmenut fluchtend zur ersten Aufnahmenut angeordnet ist. Hierdurch kann eine erste Aufnahmenut einer zweiten Aufnahmenut räumlich zugeordnet sein. Dies erlaubt weitere vorteilhafte Befestigungsmöglichkeiten der Funktionselemente an der ersten und der zweiten Aufnahmenut.According to an advantageous embodiment of the invention it is provided that the second receiving groove is arranged in alignment with the first receiving groove. As a result, a first receiving groove can be spatially assigned to a second receiving groove. This allows further advantageous fastening options for the functional elements on the first and second receiving grooves.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der Steckverbinder mehrteilig aus einzelnen Steckverbinder-Segmenten zusammengesetzt ist, wobei jedes Steckverbinder-Segment ein eigenes Gehäuse aufweist und das Gehäuse des Steckverbinders wenigstens zum Teil aus den zusammengesetzten Gehäusen der Steckverbinder-Segmente gebildet ist. Hierbei kann der Steckverbinder Steckverbinder-Segmente mit einem eigenem Gehäuse aufweisen, das jeweils eine erste und eine zweite Aufnahmenut, wie zuvor erläutert, aufweist. Der Steckverbinder kann auch Steckverbinder-Segmente mit einem eigenen Gehäuse aufweisen, das keine solchen Aufnahmenuten aufweist oder nur eine erste oder nur eine zweite Aufnahmenut der zuvor beschriebenen Art aufweist. Auf diese Weise kann das Gehäuse des Steckverbinders variabel nach Bedarf des Anwenders mit unterschiedlichen Konfigurationen von ersten und zweiten Aufnahmenuten gebildet sein. Insbesondere kann der Steckverbinder ausschließlich aus Steckverbinder-Segmenten mit jeweils einer ersten und einer zweiten Aufnahmenut ausgebildet sein. Hierdurch ergibt sich eine maximale Auswahl für die Anbringung von Funktionselementen am Steckverbinder für den Anwender.According to an advantageous embodiment of the invention it is provided that the connector is composed in several parts from individual connector segments, each connector segment having its own housing and the housing of the connector is at least partially formed from the assembled housings of the connector segments. Here, the connector can have connector segments with their own housing, each of which has a first and a second receiving groove, as explained above. The connector can also have connector segments with their own housing which does not have any such receiving grooves or has only a first or only a second receiving groove of the type described above. In this way, the housing of the plug connector can be formed variably as required by the user with different configurations of first and second receiving grooves. In particular, the connector can be formed exclusively from connector segments, each with a first and a second receiving groove. This results in a maximum selection for the attachment of functional elements on the connector for the user.
Die Erfindung betrifft außerdem eine elektrische Steckverbindung, die einen Steckverbinder der zuvor erläuterten Art und einen dem Steckverbinder als Gegenstück zugeordneten Gegensteckverbinder aufweist, an den der Steckverbinder in einer Steckrichtung ansteckbar ist oder angesteckt ist. Auch hierdurch können die zuvor erläuterten Vorteile realisiert werden.The invention also relates to an electrical plug connection which has a plug connector of the type explained above and a mating plug connector assigned to the plug connector as a counterpart, to which the plug connector can be or is plugged in in one plugging direction. The advantages explained above can also be realized in this way.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der Gegensteckverbinder ein Gehäuse und mehrere zumindest teilweise in dem Gehäuse angeordnete elektrische Steckkontakte aufweist, die in einer Anreihrichtung nebeneinander angeordnet sind, wobei eine dritte Gehäusewand des Gehäuses des Gegensteckverbinders, die parallel zu einer durch die Steckrichtung und die Anreihrichtung aufgespannten Ebene angeordnet ist, an eine vierte Gehäusewand des Gehäuses des Gegensteckverbinders angrenzt, die in Steckrichtung weist und abgewinkelt zur dritten Gehäusewand angeordnet ist, mit folgenden Merkmalen:
- a) die dritte Gehäusewand weist wenigstens eine mit ihrer Längsrichtung in Steckrichtung verlaufende dritte Aufnahmenut zur Aufnahme eines Funktionselements auf,
- b) die vierte Gehäusewand weist wenigstens eine vierte Aufnahmenut zur Aufnahme eines Funktionselements auf.
- a) the third housing wall has at least one third receiving groove with its longitudinal direction in the insertion direction for receiving a functional element,
- b) the fourth housing wall has at least one fourth receiving groove for receiving a functional element.
Auf diese Weise kann der Gegensteckverbinder in vergleichbarer Weise vorteilhaft weitergebildet werden, wie zuvor für den Steckverbinder beschrieben wurde. Am Gegensteckverbinder lassen sich somit sämtliche der zuvor für den Steckverbinder erläuterten Merkmale in gleicher Weise realisieren, wobei beim Gegensteckverbinder die dritte Gehäusewand der ersten Gehäusewand des Steckverbinders entspricht, und die vierte Gehäusewand der zweiten Gehäusewand des Steckverbinders. Dementsprechend entsprechen bei dem Gegensteckverbinder die dritte Aufnahmenut der ersten Aufnahmenut des Steckverbinders und die vierte Aufnahmenut der zweiten Aufnahmenut des Steckverbinders.In this way, the mating connector can be advantageously developed in a comparable manner to that described above for the connector. On the mating connector, all of the features explained above for the connector can thus be implemented in the same way, with the mating connector having the third housing wall corresponding to the first housing wall of the connector and the fourth housing wall corresponding to the second housing wall of the connector. Correspondingly, in the mating connector, the third receiving groove corresponds to the first receiving groove of the plug connector and the fourth receiving groove corresponds to the second receiving groove of the plug connector.
Die Erfindung betrifft außerdem ein Set aus wenigstens einem Steckverbinder der zuvor erläuterten Art und wenigstens einem Funktionselement, das wenigstens einen in der ersten Aufnahmenut und/oder der zweiten Aufnahmenut befestigbaren Befestigungsbereich aufweist. Auch hierdurch können die zuvor erläuterten Vorteile realisiert werden.The invention also relates to a set comprising at least one connector of the type explained above and at least one functional element which has at least one fastening area that can be fastened in the first receiving groove and / or the second receiving groove. The advantages explained above can also be realized in this way.
Im Sinne der vorliegenden Erfindung ist unter dem unbestimmten Begriff "ein" kein Zahlwort zu verstehen. Wenn also z.B. von einem Bauteil die Rede ist, so ist dies im Sinne von "mindestens einem Bauteil" zu interpretieren. Soweit Winkelangaben in Grad gemacht werden, beziehen sich diese auf ein Kreismaß von 360 Grad (360°).In the context of the present invention, the indefinite term “a” is not to be understood as a numerical word. So if e.g. If a component is mentioned, this is to be interpreted in the sense of "at least one component". As far as angles are given in degrees, these refer to a circle of 360 degrees (360 °).
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen unter Verwendung von Zeichnungen näher erläutert.The invention is explained in more detail below on the basis of exemplary embodiments using drawings.

Die Anreihrichtung A definiert insbesondere die Anordnung, in der in dem Gehäuse 2 angeordnete elektrische Steckkontakte des Steckverbinders 1 nebeneinander angeordnet sind. In dem in
Das Gehäuse 2 weist eine Abstufung 3 auf, die in die Steckrichtung S weist. Die Abstufung 3 wird durch aneinander grenzende Gehäusewände gebildet, und zwar eine erste Gehäusewand 10, die parallel zu einer durch die Steckrichtung S und die Anreihrichtung A aufgespannten Ebene angeordnet ist, und eine zweite Gehäusewand 20, die an die erste Gehäusewand 10 angrenzt. Die zweite Gehäusewand 20 weist ebenfalls in Steckrichtung S und ist in einem Winkel zur ersten Gehäusewand 10 angeordnet, z. B. in einem rechten Winkel.The

Der Steckverbinder 1 bzw. dessen Gehäuse 2 endet in Steckrichtung S mit dem Steckgesicht 4. Von der Seite des Steckgesichts 4 führen jeweilige Kontaktöffnungen 50 zu den in dem Gehäuse 2 angeordneten elektrischen Steckkontakten des Steckverbinders 1.The
Das Gehäuse 2 weist zur Befestigung von Funktionselementen erste Aufnahmenuten 11 in der ersten Gehäusewand 10 und zweite Aufnahmenuten 21 in der zweiten Gehäusewand 20 auf. Die ersten Aufnahmenuten 11 verlaufen mit ihrer Längsrichtung in Steckrichtung S. Die zweiten Aufnahmenuten 21 verlaufen in diesem Ausführungsbeispiel mit ihrer Längsrichtung senkrecht zu der durch die Steckrichtung S und die Anreihrichtung A aufgespannten Ebene.The

Durch die erkennbare Fixierung des ersten Rastelements 81 über die im Winkel verlaufenden Befestigungsbereiche 83, 84 wird eine besonders zuverlässige Fixierung am Steckverbinder bewirkt, da hierdurch eine Art Stützgeometrie bereitgestellt ist, die die auf die Aufnahmenuten 11, 21 einwirkenden Drehmomente bei Zugbeanspruchung abfängt und so ein Herauslösen des Funktionselements 8 im Sinne eines Herausdrehens verhindert. Durch die Auflage des Rastelements 90 des Gegensteckverbinders 9 auf dem zweiten Befestigungsabschnitt 84 des ersten Rastelements wird zudem das erste Rastelement 81 sicher in den Aufnahmenuten 11, 21 gehalten, insbesondere kann das erste Rastelement 81 nicht aus der zweiten Aufnahmenut 21 entgegen der Einführrichtung herausgleiten.The recognizable fixation of the

Bei den bisher beschriebenen Ausführungsformen waren die erste Aufnahmenut 11 und die zweite Aufnahmenut 21, die einander zugeordnet sind, jeweils derart ausgebildet, dass im Schnittbereich 30 die eine Aufnahmenut an dem Nutgrund der jeweiligen anderen Aufnahmenut endet. Eine solche Ausführungsform ist allerdings nicht zwingend. Die erste und/oder die zweite Aufnahmenut 11, 21 kann auch noch weiter in diesem Schnittbereich 30 verlängert sein, sodass sie über den Nutgrund der jeweiligen zugeordneten anderen Aufnahmenut hinausgeht. Auf diese Weise bildet sich in dem Nutgrund der jeweiligen senkrecht dazu verlaufenden Aufnahmenut eine Vertiefung. Eine solche Vertiefung kann zur Aufnahme eines Endes eines Funktionselements genutzt werden. Dieses Ende des Funktionselements kann in der jeweiligen Vertiefung verrastend (Rastkanten) und/oder klemmend aufgenommen werden. Auf diese Weise können Ausziehkräfte und/oder auf das Funktionselement einwirkende Drehmomente aufgenommen und neutralisiert werden.In the embodiments described so far, the first receiving
