Definitions
- the invention relates to an electrical connector for connection to a complementary mating connector.
- electrical connectors In order to connect electrical cables either to one another or to an electrical component, electrical connectors are generally used, which can be releasably connected to a complementary mating connector and thus produce an electrically conductive connection.
- the cable is connected to the connector.
- the mating connector on the other hand, is electrically conductively connected to the partner to be connected, so that when the connector and mating connector are connected, an electrically conductive connection is produced between the cable and the respective partner to be connected.
- Additional security systems are often used, particularly in the case of connectors where it must be ensured that the connection between the cable and the connector and/or between the connector and the mating connector is correct.
- a secondary lock can be provided, which can provide additional attachment of the cable on or in the connector.
- the connector can have a plug-in prevention that prevents a connection of the connector and the mating connector if the cable is not correctly connected to the connector and/or the partner to be connected is not correctly connected to the mating connector.
- the DE 10 2004 054 572 A1 discloses an electrical connector assembly having an insulative housing and an insulative terminal position assurance member.
- the terminal position assurance actuator has a pre-locking position in which corresponding latching members abut, whereby accidental activation and locking of the terminal position assurance actuator can be prevented.
- the terminal includes a projection that engages the terminal position assurance member and allows the terminal position assurance member to move to a fully latched position.
- the U.S. 5,730,627 A discloses a terminal holding structure for a connector in which a terminal holding member is allowed to enter a connector housing from an opening facing a terminal accommodating chamber of the connector housing.
- the terminal holding member has a terminal holding projection on its front and a notched stepped portion on its rear.
- a primary temporary holding projection and a secondary temporary holding projection are arranged on an overhanging wall portion so as to be offset in a terminal holding member insertion direction.
- the overhanging wall portion has the terminal holding projection of the terminal holding member projecting therefrom.
- the primary temporary holding projection and the secondary temporary holding projection can be sequentially engaged with the side end edges of the opening.
- the indented stepped portion is brought into contact with and supported on an outer casing wall after the secondary temporary retaining projection has passed the corresponding lateral end edge of the opening.
- the terminal holding projection may obliquely enter the opening to contact the inner case wall.
- the DE 10 2004 005 880 A1 discloses a tubular connector housing capable of receiving a contact element connected to an electrical cable.
- An inner holder is accommodated in the housing in such a way that the contact elements are held therein positioned.
- the inner holder can be slidably moved between a first engaged position in which it is possible to pull out the contact elements from the connector housing and a second engaged position in which the contact elements are prevented from being pulled out from the connector housing.
- a through hole is formed in a side wall of the connector housing such that part of an outer side surface of the inner holder is operable therethrough to allow the inner holder to be displaced between the first mating position and the second mating position.
- An electrical connector according to the invention for, in particular mechanical and electrical, connection to a complementary mating connector has at least one housing.
- the housing includes at least one plug-in chamber.
- the housing can also have a plurality of plug-in chambers, preferably two plug-in chambers, more preferably four plug-in chambers.
- the plug-in chamber preferably has a cylindrical shape.
- the plug connector also has at least one contact arrangement which is at least partially arranged within the plug-in chamber.
- the plug-in chamber is preferably accessible from outside the housing at least at two points, which are particularly preferably opposite one another, so that the contact arrangement can be introduced into the plug-in chamber at a first point and an electrically conductive connection with the mating connector can be produced at the second point .
- the contact arrangement can be composed of one or more conductive elements which are electrically conductive connection with a cable. If the cable is a coaxial cable, the contact arrangement can have, for example, an inner conductor contact that is connected to the inner conductor of the cable and an outer conductor contact that is connected to the outer conductor of the cable. If the housing has a plurality of plug-in chambers, one contact arrangement can be provided for each plug-in chamber.
- the electrical plug connector also includes a fastening element, which fastens the contact arrangement, which is at least partially arranged in the plug-in chamber, in the plug-in chamber. If the housing has a number of plug-in chambers for a number of contact arrangements, one fastening element can be provided for each plug-in chamber.
- the fastening element preferably detachably fastens the contact arrangement, for example by means of a form fit and/or a force fit within the plug-in chamber.
- the fastening element can, for example, have a latching lug which engages in a complementary contour in the contact arrangement. In order to provide the fastening element particularly efficiently, it is advantageous if the fastening element and the housing are designed in one piece.
- the electrical connector includes a secondary fuse that is movable between a pre-locked position and an end-locked position.
- the secondary fuse is preferably connected to the housing both in the pre-locked position and in the end-locked position.
- the secondary safety device can serve as a plug-in prevention device, so that the electrical connector cannot be connected to the mating connector when the secondary safety device is in the pre-locked position.
- the secondary safeguard secures the fastening element against loosening of the fastening of the contact arrangement in the plug-in chamber. This can be done, for example, by the secondary safety device at least restricting or, more preferably, preventing the mobility of the fastening element in the final locking position.
- the secondary safety device In the final latching position, the secondary safety device thus prevents the fastening of the contact arrangement within the plug-in chamber from being released by the fastening element. If you intend to loosen this attachment, the secondary safety device must first be moved from the final locking position back to the pre-locking position.
- the housing has a fastening groove at least in sections along the plug-in chamber.
- the fastening groove is preferably open towards the plug-in chamber and preferably has an angular, in particular square, cross-sectional geometry. If the housing has a number of plug-in chambers, a number of fastening grooves can also be provided.
- a fastening groove is preferably assigned to each plug-in chamber. If several fastening grooves are provided, the fastening grooves are particularly preferably arranged parallel to one another. Furthermore, the fastening groove preferably runs parallel to a direction of longitudinal extension of the plug-in chamber.
- the secondary safety device has at least one locking element which engages in the fastening groove in the final locking position.
- the latching element positively connects the secondary fuse to the housing and the secondary fuse is held in the final latched position by the latching element. It is particularly preferred at this point that the latching element remains outside the plug-in chamber in the final latched position, in other words it only protrudes into the fastening groove but not into the plug-in chamber.
- the fastening element has a latching arm, which is elastically deformable, for example, to produce the fastening of the contact arrangement within the plug-in chamber.
- the locking arm has a main extension direction which runs parallel to a longitudinal extension direction of the plug-in chamber.
- a latching lug is arranged on a side facing the plug-in chamber, which protrudes at least partially into the plug-in chamber and at least partially engages in a recess in the cable arrangement.
- the fastening element therefore has a support element on a side facing away from the plug-in chamber and particularly preferably on a side facing the secondary fuse, which is at least partially arranged in an opening of the secondary fuse, at least in the final locking position. If the housing has a plurality of plug-in chambers, each with a fastening element, it can be advantageous if each fastening element has a support element. At this point, it is particularly preferred that in this case the secondary fuse has a plurality of openings, so that a plurality of support elements can each engage one of the openings of a secondary fuse.
- the support element is arranged outside the opening in the pre-locked position.
- the support element can be designed, for example, as a projection that protrudes from the fastening element. If the fastening element has a latching arm and a latching lug, it is particularly advantageous if the support element is arranged on the latching arm opposite the latching lug
- the structure according to the invention makes it possible to provide a plug connector that can be produced with significantly less manufacturing effort, in particular by injection molding. Since the housing has a fastening groove open to the plug-in chamber, which is also used for the positive connection of the secondary fuse, at least in the final locking position, a significantly simpler geometry of the required injection molding tool can be selected in order to be able to produce the electrical connector according to the invention, since complex slide systems are required to produce the Plug-in chamber and other mounting options for the secondary fuse can be dispensed with.
- the support element can abut against at least one side surface of the opening of the secondary safety device. It is particularly advantageous at this point if the support element abuts against a side face that runs parallel to a narrow side of the latching arm.
- the secondary lock and/or the housing can have positioning elements, for example crushing ribs, which ensure that the side surface is in contact with the support element.
- the housing can have a recess on a side wall.
- the recess is adjacent to the plug-in chamber in such a way that the plug-in chamber is accessible via the recess.
- the fastening groove is preferably also accessible via the recess.
- the fastener can also be at least partially within the recess be arranged. If the housing has a number of plug-in chambers, a number of plug-in chambers can also be accessible via the recess and/or a number of fastening elements can be arranged at least within the recess.
- the fastening groove preferably extends from a plug-in side of the housing to the recess.
- the plug-in side of the housing can be understood to mean the side of the housing on which the housing can be connected to a complementary mating connector.
- the fastening groove is exposed towards the plug-in side and towards the recess.
- the plug-in chamber can have at least one end stop on the plug-in side.
- the end stop can serve as a stop for the contact arrangement, so that the contact arrangement cannot be guided through the plug-in chamber beyond the plug-in side.
- the end stop can be implemented, for example, by reducing the diameter, the diameter in the end stop being smaller in this case than the outside diameter of the contact arrangement.
- the end stop can have a gap in the area of the fastening groove, so that the fastening groove is still exposed on the mating side despite the end stop.
- the fastening groove is preferably arranged in a region of the plug-in chamber which faces the side wall of the housing in which the recess is made.
- the secondary safety device can be arranged at least partially within the recess, at least in the final locking position.
- the locking element which engages in the fastening groove at least in the final locking position, can be guided at least partially through the recess in the final locking position, so that the locking element engages in the fastening groove via the recess.
- the secondary fuse can have at least one locking element, which protrudes into the plug-in chamber in the final locking position and fastens the contact arrangement in the plug-in chamber.
- the locking element means that the contact arrangement is consequently fastened not only by the fastening element, but also by the secondary fuse in the plug-in chamber. If the housing has multiple plug-in chambers, the secondary fuse can have multiple locking elements, so that multiple Contact arrangements can also be attached in different plug-in chambers with a secondary fuse.
- the secondary safety device can have an unlocking aid.
- the unlocking aid can be designed, for example, in the form of a slot, so that the secondary safety device can be moved, for example, by inserting a dismantling aid into the slot.
- the unlocking aid can be designed, for example, as a projection that creates an alignment between the housing and the secondary fuse. A dismantling tool can then be arranged within the escape and the secondary safety device can be levered back into the pre-locked position.
- the housing has at least two plug-in chambers, it is preferred that the housing has a fastening groove open to the plug-in chamber for each plug-in chamber. At least in the final locking position, the secondary safety device can engage with a respective locking element in a respective fastening groove, so that the secondary safety device engages in both fastening grooves via the locking elements.

Description
Die Erfindung betrifft einen elektrischen Steckverbinder zum Verbinden mit einem komplementären Gegensteckverbinder.The invention relates to an electrical connector for connection to a complementary mating connector.
Um elektrische Kabel entweder miteinander oder mit einem elektrischen Bauteil zu verbinden, werden in der Regel elektrische Steckverbinder verwendet, die mit einem komplementären Gegensteckverbinder lösbar verbunden werden können und somit eine elektrisch leitende Verbindung herstellen. Hierbei ist das Kabel mit dem Steckverbinder verbunden. Der Gegensteckverbinder ist hingegen mit dem zu verbindenden Partner elektrisch leitend verbunden, so dass beim Verbinden von Steckverbinder und Gegensteckverbinder eine elektrisch leitende Verbindung zwischen Kabel und dem jeweiligen zu verbindenden Partner erzeugt wird.In order to connect electrical cables either to one another or to an electrical component, electrical connectors are generally used, which can be releasably connected to a complementary mating connector and thus produce an electrically conductive connection. Here the cable is connected to the connector. The mating connector, on the other hand, is electrically conductively connected to the partner to be connected, so that when the connector and mating connector are connected, an electrically conductive connection is produced between the cable and the respective partner to be connected.
Insbesondere bei Steckverbindern, bei denen sichergestellt werden muss, dass sowohl die Verbindung zwischen Kabel und Steckverbinder und/oder zwischen Steckverbinder und Gegensteckverbinder korrekt vorliegt, kommen häufig zusätzliche Sicherungssysteme zum Einsatz. Beispielsweise kann eine Sekundärverriegelung vorgesehen sein, die für eine zusätzliche Befestigung des Kabels am oder im Steckverbinder sorgen kann. Weiterhin kann der Steckverbinder eine Steckverhinderung aufweisen, die eine Verbindung von Steckverbinder und Gegensteckverbinder verhindert, wenn das Kabel nicht korrekt mit dem Steckverbinder und/oder der zu verbindende Partner nicht korrekt mit dem Gegensteckverbinder verbunden ist. Weiterhin kann es je nach verfügbaren Bauraum erforderlich sein, dass mehrere Kabel mithilfe eines Steckverbinders mit einem entsprechenden komplementären Gegensteckverbinder verbunden werden.Additional security systems are often used, particularly in the case of connectors where it must be ensured that the connection between the cable and the connector and/or between the connector and the mating connector is correct. For example, a secondary lock can be provided, which can provide additional attachment of the cable on or in the connector. Furthermore, the connector can have a plug-in prevention that prevents a connection of the connector and the mating connector if the cable is not correctly connected to the connector and/or the partner to be connected is not correctly connected to the mating connector. Furthermore, depending on the available installation space, it may be necessary for several cables to be connected to a corresponding complementary mating connector using a connector.
Sowohl die zusätzlichen Sicherungssysteme als auch die Anforderung mit einem Steckverbinder mehrere Kabel verbinden zu können steigern jedoch die Komplexität des Steckverbinders deutlich. Insbesondere bei kleinen Steckverbindern, wie sie beispielsweise bei Hochfrequenzkabeln zum Einsatz kommen, entsteht durch die umfangreichen Funktionen ein erhöhter Fertigungsaufwand des Steckverbinders.However, both the additional safety systems and the requirement to be able to connect several cables with one connector significantly increase the complexity of the connector. In the case of small connectors in particular, such as those used in high-frequency cables, the extensive functions mean that the connector is more complex to manufacture.

Es ist daher eine Aufgabe der vorliegenden Erfindung einen elektrischen Steckverbinder bereitzustellen, der zumindest einen im Stand der Technik genannten Nachteil überwindet und einen geringeren Komplexitätsgrad bei gleichbleibender Funktionalität aufweist.It is therefore an object of the present invention to provide an electrical plug connector that overcomes at least one disadvantage mentioned in the prior art and has a lower degree of complexity with the same functionality.
Die erfindungsgemäße Aufgabe wird durch einen elektrischen Steckverbinder mit den Merkmalen des unabhängigen Anspruchs gelöst. Weitere vorteilhafte Ausgestaltungsformen der Erfindung lassen sich den Unteransprüchen, der Beschreibung sowie den Zeichnungen entnehmen.The object according to the invention is achieved by an electrical connector having the features of the independent claim. Further advantageous embodiments of the invention can be found in the dependent claims, the description and the drawings.
Ein erfindungsgemäßer elektrischer Steckverbinder zum, insbesondere mechanischen und elektrischen, Verbinden mit einem komplementären Gegensteckverbinder weist zumindest ein Gehäuse auf. Das Gehäuse umfasst zumindest eine Steckkammer. Das Gehäuse kann jedoch auch mehrere Steckkammern, bevorzugt zwei Steckkammern, noch bevorzugter vier Steckkammern, aufweisen. Die Steckkammer weist bevorzugt eine zylindrische Form auf. Der Steckverbinder weist weiterhin zumindest eine Kontaktanordnung auf, die zumindest teilweise innerhalb der Steckkammer angeordnet ist. Die Steckkammer ist bevorzugt zumindest an zwei Stellen, die sich besonders bevorzugt gegenüberliegen, von außerhalb des Gehäuses zugänglich, so dass an einer ersten Stelle die Kontaktanordnung in die Steckkammer eingebracht werden kann und über die zweite Stelle eine elektrisch leitende Verbindung mit dem Gegensteckverbinder erzeugt werden kann. Die Kontaktanordnung kann aus einem oder mehreren leitenden Elementen zusammengesetzt sein, die in elektrisch leitender Verbindung mit einem Kabel stehen. Sofern es sich bei dem Kabel um ein Koaxialkabel handelt, kann die Kontaktanordnung beispielsweise einen Innenleiterkontakt, der mit dem Innenleiter des Kabels verbunden ist und einen Außenleiterkontakt, der mit dem Außenleiter des Kabels verbunden ist aufweisen. Sofern das Gehäuse mehrere Steckkammern aufweist, kann für jede Steckkammer jeweils eine Kontaktanordnung vorgesehen sein.An electrical connector according to the invention for, in particular mechanical and electrical, connection to a complementary mating connector has at least one housing. The housing includes at least one plug-in chamber. However, the housing can also have a plurality of plug-in chambers, preferably two plug-in chambers, more preferably four plug-in chambers. The plug-in chamber preferably has a cylindrical shape. The plug connector also has at least one contact arrangement which is at least partially arranged within the plug-in chamber. The plug-in chamber is preferably accessible from outside the housing at least at two points, which are particularly preferably opposite one another, so that the contact arrangement can be introduced into the plug-in chamber at a first point and an electrically conductive connection with the mating connector can be produced at the second point . The contact arrangement can be composed of one or more conductive elements which are electrically conductive connection with a cable. If the cable is a coaxial cable, the contact arrangement can have, for example, an inner conductor contact that is connected to the inner conductor of the cable and an outer conductor contact that is connected to the outer conductor of the cable. If the housing has a plurality of plug-in chambers, one contact arrangement can be provided for each plug-in chamber.
Der elektrische Steckverbinder umfasst des Weiteren ein Befestigungselement, das die zumindest teilweise in der Steckkammer angeordnete Kontaktanordnung in der Steckkammer befestigt. Weist das Gehäuse mehrere Steckkammern für mehrere Kontaktanordnungen auf, kann für jede Steckkammer jeweils ein Befestigungselement vorgesehen sein. Das Befestigungselement befestigt die Kontaktanordnung bevorzugt lösbar beispielsweise durch einen Formschluss und/oder einen Kraftschluss innerhalb der Steckkammer. Das Befestigungselement kann zum Beispiel eine Rastnase aufweisen, die in eine komplementäre Kontur in der Kontaktanordnung eingreift. Um das Befestigungselement besonders effizient bereitzustellen, ist es von Vorteil, wenn das Befestigungselement und das Gehäuse einstückig ausgebildet sind.The electrical plug connector also includes a fastening element, which fastens the contact arrangement, which is at least partially arranged in the plug-in chamber, in the plug-in chamber. If the housing has a number of plug-in chambers for a number of contact arrangements, one fastening element can be provided for each plug-in chamber. The fastening element preferably detachably fastens the contact arrangement, for example by means of a form fit and/or a force fit within the plug-in chamber. The fastening element can, for example, have a latching lug which engages in a complementary contour in the contact arrangement. In order to provide the fastening element particularly efficiently, it is advantageous if the fastening element and the housing are designed in one piece.
Der elektrische Steckverbinder umfasst eine Sekundärsicherung, die zwischen einer Vorraststellung und einer Endraststellung bewegbar ist. Die Sekundärsicherung ist vorzugsweise sowohl in der Vorraststellung als auch in der Endraststellung mit dem Gehäuse verbunden. In der Vorraststellung kann die Sekundärsicherung als Steckverhinderung dienen, so dass sich der elektrische Steckverbinder nicht mit dem Gegensteckverbinder verbinden lässt, wenn die Sekundärsicherung sich in der Vorraststellung befindet. In der Endraststellung sichert die Sekundärsicherung das Befestigungselement gegen ein Lösen der Befestigung der Kontaktanordnung in der Steckkammer. Dies kann beispielsweise erfolgen, indem die Sekundärsicherung in der Endraststellung die Beweglichkeit des Befestigungselements zumindest einschränkt oder bevorzugter verhindert. Die Sekundärsicherung verhindert somit in der Endraststellung, dass die Befestigung der Kontaktanordnung innerhalb der Steckkammer durch das Befestigungselement gelöst werden kann. Ist ein Lösen dieser Befestigung beabsichtigt, muss die Sekundärsicherung zuerst aus der Endraststellung zurück in die Vorraststellung bewegt werden.The electrical connector includes a secondary fuse that is movable between a pre-locked position and an end-locked position. The secondary fuse is preferably connected to the housing both in the pre-locked position and in the end-locked position. In the pre-locked position, the secondary safety device can serve as a plug-in prevention device, so that the electrical connector cannot be connected to the mating connector when the secondary safety device is in the pre-locked position. In the final latching position, the secondary safeguard secures the fastening element against loosening of the fastening of the contact arrangement in the plug-in chamber. This can be done, for example, by the secondary safety device at least restricting or, more preferably, preventing the mobility of the fastening element in the final locking position. In the final latching position, the secondary safety device thus prevents the fastening of the contact arrangement within the plug-in chamber from being released by the fastening element. If you intend to loosen this attachment, the secondary safety device must first be moved from the final locking position back to the pre-locking position.
Das Gehäuse weist entlang der Steckkammer zumindest abschnittsweise eine Befestigungsnut auf. Die Befestigungsnut ist bevorzugt zur Steckkammer geöffnet und weist bevorzugt eine eckige, insbesondere viereckige Querschnittsgeometrie auf. Sofern das Gehäuse mehrere Steckkammern aufweist, können auch mehrere Befestigungsnuten vorgesehen sein. Bevorzugt ist jeder Steckkammer eine Befestigungsnut zugeordnet. Sofern mehrere Befestigungsnuten vorgesehen sind, sind die Befestigungsnuten besonders bevorzugt parallel zueinander angeordnet. Weiterhin verläuft die Befestigungsnut bevorzugt parallel zu einer Längserstreckungsrichtung der Steckkammer. Die Sekundärsicherung weist zumindest ein Rastelement auf, das in der Endraststellung in die Befestigungsnut eingreift. Es ist an dieser Stelle bevorzugt, dass das Rastelement die Sekundärsicherung mit dem Gehäuse formschlüssig verbindet und die Sekundärsicherung durch das Rastelement in der Endraststellung gehalten wird. Es ist an dieser Stelle besonders bevorzugt, dass das Rastelement in der Endraststellung außerhalb der Steckkammer verbleibt, mit anderen Worten also nur in die Befestigungsnut jedoch nicht in die Steckkammer hineinragt.The housing has a fastening groove at least in sections along the plug-in chamber. The fastening groove is preferably open towards the plug-in chamber and preferably has an angular, in particular square, cross-sectional geometry. If the housing has a number of plug-in chambers, a number of fastening grooves can also be provided. A fastening groove is preferably assigned to each plug-in chamber. If several fastening grooves are provided, the fastening grooves are particularly preferably arranged parallel to one another. Furthermore, the fastening groove preferably runs parallel to a direction of longitudinal extension of the plug-in chamber. The secondary safety device has at least one locking element which engages in the fastening groove in the final locking position. It is preferred at this point that the latching element positively connects the secondary fuse to the housing and the secondary fuse is held in the final latched position by the latching element. It is particularly preferred at this point that the latching element remains outside the plug-in chamber in the final latched position, in other words it only protrudes into the fastening groove but not into the plug-in chamber.
Das Befestigungselement weist einen Rastarm auf, der beispielsweise zur Erzeugung der Befestigung der Kontaktanordnung innerhalb der Steckkammer elastisch verformbar ist. Der Rastarm weist dabei eine Haupterstreckungsrichtung auf, die parallel zu einer Längserstreckungsrichtung der Steckkammer verläuft. Es ist bevorzugt, dass auf einer der Steckkammer zugewandten Seite eine Rastnase angeordnet ist, die zumindest teilweise in die Steckkammer hineinragt und zumindest teilweise in eine Vertiefung in der Kabelanordnung eingreift.The fastening element has a latching arm, which is elastically deformable, for example, to produce the fastening of the contact arrangement within the plug-in chamber. In this case, the locking arm has a main extension direction which runs parallel to a longitudinal extension direction of the plug-in chamber. It is preferred that a latching lug is arranged on a side facing the plug-in chamber, which protrudes at least partially into the plug-in chamber and at least partially engages in a recess in the cable arrangement.
Steckverbindungen können sowohl während der Montage als auch nach der Montage hohen mechanischen Belastungen ausgesetzt sein, die dazu führen können, dass auch die Befestigung der Kontaktanordnung durch das Befestigungselement sehr starken Belastungen ausgesetzt sein kann. Das Befestigungselement weist daher auf einer der Steckkammer abgewandten Seite und besonders bevorzugt auf einer der Sekundärsicherung zugewandten Seite ein Stützelement auf, das zumindest in der Endraststellung zumindest teilweise in einer Öffnung der Sekundärsicherung angeordnet ist. Sofern das Gehäuse mehrere Steckkammern mit jeweils einem Befestigungselement aufweist, kann es von Vorteil sein, wenn jedes Befestigungselement jeweils ein Stützelement aufweist. Es ist an dieser Stelle besonders bevorzugt, dass in diesem Fall die Sekundärsicherung mehrere Öffnungen aufweist, so dass mehrere Stützelemente jeweils in eine der Öffnungen einer Sekundärsicherung eingreifen können. Zur leichteren Montage und Demontage kann es darüber hinaus vom Vorteil sein, wenn das Stützelement in der Vorraststellung außerhalb der Öffnung angeordnet ist. Das Stützelement kann beispielsweise als Vorsprung ausgebildet sein, der von dem Befestigungselement absteht. Sofern das Befestigungselement einen Rastarm und eine Rastnase aufweist ist es besonders vorteilhaft, wenn das Stützelement gegenüberliegend zur Rastnase an dem Rastarm angeordnet istPlug connections can be exposed to high mechanical loads both during assembly and after assembly, which can result in the fastening of the contact arrangement by the fastening element also being exposed to very high loads. The fastening element therefore has a support element on a side facing away from the plug-in chamber and particularly preferably on a side facing the secondary fuse, which is at least partially arranged in an opening of the secondary fuse, at least in the final locking position. If the housing has a plurality of plug-in chambers, each with a fastening element, it can be advantageous if each fastening element has a support element. At this point, it is particularly preferred that in this case the secondary fuse has a plurality of openings, so that a plurality of support elements can each engage one of the openings of a secondary fuse. For easier assembly and disassembly, it can also be advantageous if the support element is arranged outside the opening in the pre-locked position. The support element can be designed, for example, as a projection that protrudes from the fastening element. If the fastening element has a latching arm and a latching lug, it is particularly advantageous if the support element is arranged on the latching arm opposite the latching lug
Durch den erfindungsgemäßen Aufbau lässt sich ein Steckverbinder bereitstellen, der insbesondere im Spritzguss mit deutlich weniger Fertigungsaufwand hergestellt werden kann. Indem das Gehäuse eine zur Steckkammer geöffnete Befestigungsnut aufweist, die gleichzeitig zur formschlüssigen Verbindung der Sekundärsicherung zumindest in der Endraststellung dient, kann eine deutlich einfachere Geometrie des erforderlichen Spritzgusswerkzeuges gewählt werden, um den erfindungsgemäßen elektrischen Steckverbinder herstellen zu können, da auf komplexe Schiebersysteme zur Erzeugung der Steckkammer und weiterer Befestigungsmöglichkeiten für die Sekundärsicherung verzichtet werden kann.The structure according to the invention makes it possible to provide a plug connector that can be produced with significantly less manufacturing effort, in particular by injection molding. Since the housing has a fastening groove open to the plug-in chamber, which is also used for the positive connection of the secondary fuse, at least in the final locking position, a significantly simpler geometry of the required injection molding tool can be selected in order to be able to produce the electrical connector according to the invention, since complex slide systems are required to produce the Plug-in chamber and other mounting options for the secondary fuse can be dispensed with.
Das Stützelement kann zumindest in der Endraststellung an zumindest einer Seitenfläche der Öffnung der Sekundärsicherung anstoßen. Es ist an dieser Stelle besonders vorteilhaft, wenn das Stützelement an einer Seitenfläche anstößt, die parallel zu einer Schmalseite des Rastarms verläuft. Um sicherzustellen, dass das Stützelement nach dem Bewegen der Sekundärsicherung von der Vorraststellung in die Endraststellung an der Seitenfläche der Öffnung anstößt, kann die Sekundärsicherung und/oder das Gehäuse Positionierungselemente, beispielsweise Quetschrippen, aufweisen, die das Anlegen der Seitenfläche an das Stützelement sicherstellen. Durch das Anlegen der Seitenfläche an das Stützelement können Kräfte, die auf das Befestigungselement wirken, effektiver auf die Sekundärsicherung abgeleitet werden.At least in the final locking position, the support element can abut against at least one side surface of the opening of the secondary safety device. It is particularly advantageous at this point if the support element abuts against a side face that runs parallel to a narrow side of the latching arm. In order to ensure that the support element abuts against the side surface of the opening after the secondary lock has been moved from the pre-locked position to the end lock position, the secondary lock and/or the housing can have positioning elements, for example crushing ribs, which ensure that the side surface is in contact with the support element. By applying the side surface to the support element, forces acting on the fastening element can be diverted more effectively to the secondary fuse.
Das Gehäuse kann an einer Seitenwand eine Ausnehmung aufweisen. Die Ausnehmung grenzt dabei derart an die Steckkammer an, dass die Steckkammer über die Ausnehmung zugänglich ist. Bevorzugt ist die Befestigungsnut ebenfalls über die Ausnehmung zugänglich. Das Befestigungselement kann ebenfalls zumindest teilweise innerhalb der Ausnehmung angeordnet sein. Sofern das Gehäuse mehrere Steckkammern aufweist, können auch mehrere Steckkammern über die Ausnehmung zugänglich und/oder mehrere Befestigungselemente zumindest innerhalb der Ausnehmung angeordnet sein.The housing can have a recess on a side wall. The recess is adjacent to the plug-in chamber in such a way that the plug-in chamber is accessible via the recess. The fastening groove is preferably also accessible via the recess. The fastener can also be at least partially within the recess be arranged. If the housing has a number of plug-in chambers, a number of plug-in chambers can also be accessible via the recess and/or a number of fastening elements can be arranged at least within the recess.
Vorzugsweise erstreckt sich die Befestigungsnut von einer Steckseite des Gehäuses bis zur Ausnehmung. Unter der Steckseite des Gehäuses kann in diesem Zusammenhang die Seite des Gehäuses verstanden werden, an der das Gehäuse mit einem komplementären Gegensteckverbinder verbindbar ist. Weiterhin ist es bevorzugt, dass die Befestigungsnut zur Steckseite und zur Ausnehmung hin freiliegt.The fastening groove preferably extends from a plug-in side of the housing to the recess. In this context, the plug-in side of the housing can be understood to mean the side of the housing on which the housing can be connected to a complementary mating connector. Furthermore, it is preferred that the fastening groove is exposed towards the plug-in side and towards the recess.
Die Steckkammer kann an der Steckseite zumindest einen Endanschlag aufweisen. Der Endanschlag kann als Anschlag für die Kontaktanordnung dienen, so dass die Kontaktanordnung nicht über die Steckseite hinaus aus durch die Steckkammer geführt werden kann. Der Endanschlag kann beispielsweise durch eine Durchmesserreduzierung realisiert sein, wobei der Durchmesser im Endanschlag in diesem Fall kleiner ist als der Außendurchmesser der Kontaktanordnung. Im Bereich der Befestigungsnut kann der Endanschlag eine Lücke aufweisen, so dass die Befestigungsnut trotz Endanschlag weiterhin an der Steckseite freiliegt. Die Befestigungsnut ist vorzugsweise in einem Bereich der Steckkammer angeordnet, der der Seitenwand des Gehäuses, in die die Ausnehmung eingebracht ist, zugewandt ist.The plug-in chamber can have at least one end stop on the plug-in side. The end stop can serve as a stop for the contact arrangement, so that the contact arrangement cannot be guided through the plug-in chamber beyond the plug-in side. The end stop can be implemented, for example, by reducing the diameter, the diameter in the end stop being smaller in this case than the outside diameter of the contact arrangement. The end stop can have a gap in the area of the fastening groove, so that the fastening groove is still exposed on the mating side despite the end stop. The fastening groove is preferably arranged in a region of the plug-in chamber which faces the side wall of the housing in which the recess is made.
Die Sekundärsicherung kann zumindest in der Endraststellung zumindest teilweise innerhalb der Ausnehmung angeordnet sein. Das Rastelement, welches zumindest in der Endraststellung in die Befestigungsnut eingreift, kann in der Endraststellung zumindest teilweise durch die Ausnehmung geführt sein, so dass das Rastelement über die Ausnehmung in die Befestigungsnut eingreift.The secondary safety device can be arranged at least partially within the recess, at least in the final locking position. The locking element, which engages in the fastening groove at least in the final locking position, can be guided at least partially through the recess in the final locking position, so that the locking element engages in the fastening groove via the recess.
Die Sekundärsicherung kann zumindest ein Verriegelungselement aufweisen, die in der Endraststellung in die Steckkammer hineinragen und die Kontaktanordnung in der Steckkammer befestigt. Durch das Verriegelungselement wird die Kontaktanordnung folglich nicht nur durch das Befestigungselement, sondern auch durch die Sekundärsicherung im der Steckkammer befestigt. Sofern das Gehäuse mehrere Steckkammern aufweist, kann die Sekundärsicherung mehrere Verriegelungselemente aufweisen, so dass auch mehrere Kontaktanordnungen in verschiedenen Steckkammern mit einer Sekundärsicherung zusätzlich befestigt werden können.The secondary fuse can have at least one locking element, which protrudes into the plug-in chamber in the final locking position and fastens the contact arrangement in the plug-in chamber. The locking element means that the contact arrangement is consequently fastened not only by the fastening element, but also by the secondary fuse in the plug-in chamber. If the housing has multiple plug-in chambers, the secondary fuse can have multiple locking elements, so that multiple Contact arrangements can also be attached in different plug-in chambers with a secondary fuse.
Um sicherstellen zu können, dass die Sekundärsicherung von Endraststellung zurück in die Vorraststellung bewegbar ist, kann die Sekundärsicherung eine Entriegelungshilfe aufweisen. Die Entriegelungshilfe kann beispielsweise in Form eines Schlitzes ausgeführt sein, so dass die Sekundärsicherung beispielsweise durch das Einführen einer Demontagehilfe in den Schlitz bewegt werden kann. Alternativ kann die Entriegelungshilfe beispielsweise als Vorsprung ausgebildet sein, der eine Flucht zwischen Gehäuse und Sekundärsicherung erzeugt. Innerhalb der Flucht kann dann ein Demontagewerkzeug angeordnet und die Sekundärsicherung zurück in die Vorraststellung gehebelt werden.In order to be able to ensure that the secondary safety device can be moved from the final locking position back into the pre-locking position, the secondary safety device can have an unlocking aid. The unlocking aid can be designed, for example, in the form of a slot, so that the secondary safety device can be moved, for example, by inserting a dismantling aid into the slot. Alternatively, the unlocking aid can be designed, for example, as a projection that creates an alignment between the housing and the secondary fuse. A dismantling tool can then be arranged within the escape and the secondary safety device can be levered back into the pre-locked position.
Sofern das Gehäuse zumindest zwei Steckkammern aufweist, ist es bevorzugt, dass das Gehäuse pro Steckkammer jeweils eine zur Steckkammer offene Befestigungsnut aufweist. Die Sekundärsicherung kann zumindest in der Endraststellung mit jeweils einem Rastelement in jeweils eine Befestigungsnut eingreifen, so dass die Sekundärsicherung in beide Befestigungsnuten über die Rastelemente eingreift.If the housing has at least two plug-in chambers, it is preferred that the housing has a fastening groove open to the plug-in chamber for each plug-in chamber. At least in the final locking position, the secondary safety device can engage with a respective locking element in a respective fastening groove, so that the secondary safety device engages in both fastening grooves via the locking elements.
