Description

Stand der TechnikState of the art

Elektrische Steckverbindungen werden in vielen Bereichen der Technik eingesetzt. Sie weisen in der Regel einen Kontaktträger mit einem elektrischen Kontakt auf. Der Kontaktträger kann als Buchse ausgeführt sein und kann einen Stecker bzw. Pin zum Herstellen einer elektrischen Verbindung aufnehmen. Eine elektrische Leitung, verlässt zum Beispiel in Form eines Kabels den Kontaktträger und verbindet den elektrischen Kontakt mit weiteren Komponenten.Electrical connectors are used in many areas of technology. They usually have a contact carrier with an electrical contact. The contact carrier may be designed as a socket and may receive a plug or pin for establishing an electrical connection. An electrical line, for example, leaves the contact carrier in the form of a cable and connects the electrical contact with other components.

Beispielsweise können derartige Steckverbindungen zum Verbinden von unterschiedlichen Komponenten in einem Kraftfahrzeug verwendet werden. Beispielsweise kann der Kontaktträger als Kabelbaumstecker ausgeführt sein. Beim Betrieb des Kraftfahrzeugs können die Steckverbindungen hohen Belastungen, insbesondere Vibrationen, ausgesetzt sein.For example, such connectors can be used to connect different components in a motor vehicle. For example, the contact carrier may be designed as a harness connector. During operation of the motor vehicle, the plug connections can be exposed to high loads, in particular vibrations.

Bewegungen können sich über das Kabel bzw. die elektrische Leitung auf die Steckverbindung übertragen. Dies kann zu einer Relativbewegung zwischen dem direkt an die elektrische Leitung angebunden elektrischen Kontakt und einem Pin führen. Derartige Relativbewegungen können zu einem Verschleiß des Kontaktträgers und damit zu einem höheren Übergangswiderstand bzw. einer geringeren Lebensdauer des Kontaktträgers führen. Dabei kann der Verschleiß bei Steckverbindungen mit relativ großen Abmessungen und großen Leitungen, wie sie zum Beispiel bei Hochstromsteckverbindungen vorkommen, besonders stark ausgeprägt sein.Movements can be transmitted via the cable or the electrical line to the connector. This can lead to a relative movement between the electrical contact directly connected to the electrical line and a pin. Such relative movements can lead to wear of the contact carrier and thus to a higher contact resistance or a shorter service life of the contact carrier. In this case, the wear on connectors with relatively large dimensions and large lines, as they occur for example in Hochstromsteckverbindungen, be particularly pronounced.

Befestigungen zwischen dem Kontaktträger und dem Stecker sind zum Beispiel aus DE 10 2004 024 530 A1 bekannt. Eine optimale Minimierung der Relativbewegung konnte bisher jedoch noch nicht erreicht werden.Fasteners between the contact carrier and the plug are made, for example DE 10 2004 024 530 A1 known. However, optimum minimization of the relative movement has not yet been achieved.

Aus der WO 2011/079991 A2 , der JP H05 17961 U , der US 2007/117429 A1 und der US 2007/123105 A1 sind Steckverbindungen mit erhöhter Steckfestigkeit bekannt.From the WO 2011/079991 A2 , of the JP H05 17961 U , of the US 2007/117429 A1 and the US 2007/123105 A1 Plug connections are known with increased plug strength.

Offenbarung der ErfindungDisclosure of the invention

Es kann daher ein Bedarf an einem verbesserten Steckersystem und einem entsprechenden Herstellungsverfahren für ein Steckersystem bestehen, die es insbesondere ermöglichen eine Relativbewegung zwischen einem elektrischen Kontakt und einem Pin zu minimieren bzw. zu verhindern.There may therefore be a need for an improved connector system and a corresponding manufacturing method for a connector system, which in particular make it possible to minimize or prevent a relative movement between an electrical contact and a pin.

Dieser Bedarf kann durch den Gegenstand der vorliegenden Erfindung gemäß den unabhängigen Ansprüchen gedeckt werden. Vorteilhafte Ausführungsformen der vorliegenden Erfindung sind in den abhängigen Ansprüchen beschrieben.This need can be met by the subject matter of the present invention according to the independent claims. Advantageous embodiments of the present invention are described in the dependent claims.

Im Folgenden werden Merkmale, Einzelheiten und mögliche Vorteile einer Vorrichtung gemäß Ausführungsformen der Erfindung im Detail diskutiert.In the following, features, details and possible advantages of a device according to embodiments of the invention will be discussed in detail.

Gemäß einem ersten Aspekt der Erfindung wird ein Steckersystem für Hochstromsteckverbindungen vorgestellt. Das Steckersystem weist einen Kabelbaumstecker mit einer elektrischen Leitung und ein Aggregat mit einer Schnittstelle zur Herstellung einer elektrischen Verbindung zwischen dem Kabelbaumstecker und dem Aggregat auf. Ferner weist das Steckersystem ein erstes Fixierelement zum formschlüssigen Fixieren des Kabelbausteckers an der Schnittstelle auf. Des Weiteren weist das Steckersystem ein zweites Fixierelement auf, welches ausgeführt ist, den Kabelbaumstecker und/oder die Leitung derart formschlüssig am Aggregat zu fixieren, dass eine Bewegung des Kabelbaumsteckers und/oder der Leitung parallel und gegebenenfalls gleichzeitig auch senkrecht zu einer Steckrichtung des Kabelbaumsteckers unterbunden ist.According to a first aspect of the invention, a connector system for high current connectors is presented. The connector system includes a harness connector with an electrical lead and an assembly having an interface for establishing an electrical connection between the harness connector and the assembly. Furthermore, the plug system has a first fixing element for the positive fixing of the cable plug connector to the interface. Furthermore, the plug system has a second fixing element, which is designed to fix the harness connector and / or the line in such a form-fitting manner on the unit that a movement of the harness connector and / or the line parallel and optionally simultaneously prevented perpendicular to a direction of insertion of the harness connector is.

Anders ausgedrückt basiert die Idee der vorliegenden Erfindung darauf, den Kabelbaumstecker und die Leitung bzw. nur den Kabelbaumstecker oder nur die Leitung so am Aggregat zu fixieren, dass keine Bewegung des Kabelbaumsteckers und der Leitung auf den Kontakt einwirkt bzw. übertragen wird. Das heißt, die Schnittstelle und der Kabelbaumstecker und insbesondere die in elektrischem Kontakt stehenden Kontaktelemente der Schnittstelle und des Kabelbaumstechers weisen ein gleiches Schwingniveau auf.In other words, the idea of the present invention is based on fixing the harness connector and the conduit or only the harness connector or only the conduit to the unit so that no movement of the harness connector and the conduit is applied to the contact. That is, the interface and the harness connector, and particularly the electrically contacting contact elements of the interface and the harness connector, have the same vibration level.

Das zweite Fixierelement fixiert spielfrei die Leitung und/oder den Kabelbaumstecker direkt am Aggregat zusätzlich zur eigentlichen Steckerverriegelung durch das erste Fixierelement. Die Fixierung mittels des zweiten Fixierelements findet dabei spielfrei zumindest parallel zur Steckrichtung statt. Anders ausgedrückt kann die Steckverbindung axial fixiert werden. Zusätzlich kann die Fixierung durch das zweite Fixierelement auch eine Bewegung senkrecht zur Steckrichtung des Kabelbaumsteckers unterbinden.The second fixing fixed without play the line and / or the harness connector directly on the unit in addition to the actual connector lock by the first fixing. The fixation by means of the second fixing takes place without play at least parallel to the direction of insertion. In other words, the connector can be fixed axially. In addition, the fixation by the second fixing element can also prevent a movement perpendicular to the insertion direction of the harness connector.

Durch die Fixierung des Kabelbaumsteckers und/oder der Leitung direkt am Aggregat, befinden sich diese Komponenten auf gleichem Schwingniveau mit dem Aggregat und der am Aggregat vorgesehenen Schnittstelle. Auf diese Weise wird die Übertragung der Bewegung auf den Kontakt reduziert. Die Relativbewegung zwischen Kontakt und Pin wird dadurch verringert. Ferner reduziert sich hierdurch auch der Verschleiß des Kontaktträgers und die Lebensdauer des Steckersystems wird erhöht.By fixing the harness connector and / or the line directly to the unit, these components are at the same vibration level with the unit and provided on the unit interface. This reduces the transmission of movement to the contact. The relative movement between contact and pin is thereby reduced. Furthermore, this also reduces the wear of the contact carrier and the life of the connector system is increased.

Das Steckersystem kann zum Beispiel in Kraftfahrzeugen zum Einsatz kommen. Ein Kabelbaum des Kraftfahrzeugs kann eine elektrische Leitung bzw. ein Kabel und an einem Ende der elektrischen Leitung einen Kabelbaumstecker aufweisen. Beispielsweise kann der Kabelbaumstecker über die elektrische Leitung mit Komponenten des Kraftfahrzeugs, wie zum Beispiel mit einem Steuergerät verbunden sein.The plug system can be used for example in motor vehicles. A wiring harness of the motor vehicle may include an electric wire and a cable and a harness connector at one end of the electric wire. For example, the harness connector may be connected via the electrical line to components of the motor vehicle, such as a controller.

Der Kabelbaumstecker kann ein Gehäuse aufweisen, innerhalb dessen ein Kontaktträger mit einem oder mit mehreren Kontaktelementen angeordnet ist. Die Kontaktelemente des Kabelbaumsteckers können dabei eine elektrische Verbindung mit auf der Schnittstelle angeordneten Kontaktelementen eingehen.The harness connector may include a housing within which a contact carrier is disposed with one or more contact elements. The contact elements of the harness connector can enter into an electrical connection with arranged on the interface contact elements.

Das Aggregat, an dem die mit dem Kabelbaumstecker zu verbindende Schnittstelle vorgesehen ist, kann zum Beispiel als weiterer Kabelbaum, als eine Platine oder als ein Verteiler ausgeführt sein. Vorzugsweise kann das Aggregat als Elektromaschine bzw. als das Gehäuse einer Elektromaschine ausgeführt sein.The aggregate on which the interface to be connected to the harness connector is provided may, for example, be embodied as a further wiring harness, as a circuit board or as a distributor. Preferably, the unit can be designed as an electric machine or as the housing of an electric machine.

Am Aggregat ist eine Schnittstelle vorgesehen, über die das Aggregat mit dem Kabelbaumstecker und auf diese Weise mit weiteren Komponenten verbindbar ist. Beispielsweise kann das Aggregat über die Schnittstelle mit Energie versorgt werden. Die Schnittstelle kann eine Schnittstellenbuchse bzw. einen Steckerkragen aufweisen. Im Steckerkragen können Kontaktelemente wie zum Beispiel Messer bzw. Pins vorgesehen sein.On the unit an interface is provided, via which the unit can be connected to the harness connector and in this way with other components is. For example, the unit can be powered via the interface with energy. The interface may have an interface socket or a plug collar. In the plug collar contact elements such as knives or pins may be provided.

Das erste Fixierelement dient der direkten Befestigung des Kabelbaumsteckers an der Schnittstelle bzw. am Schnittstellenkragen. Dabei kann das erste Fixierelement auch als Steckerverriegelung bezeichnet werden. Beispielsweise kann das erste Fixierelement manuell betätigt werden. Nach dem Verbinden des Kabelbaumsteckers mit der Schnittstelle, das heißt nach dem Einfügen des Kabelbaumsteckers in die Schnittstellenbuchse, kann das erste Fixierelement betätigt werden und den Kabelbaumstecker an der Schnittstelle bzw. an der Schnittstellenbuchse form- und ggf. kraftschlüssig fixieren. Hierzu können zum Beispiel außen an der Schnittstellenbuchse zwei gegenüberliegende, senkrecht zur Steckrichtung des Kabelbaumsteckers angeordnete Verriegelungsbolzen vorgesehen sein. Das erste Fixierelement kann dabei als Schiebeelement oder als drehbar gelagertes Hebelelement ausgeführt sein. Insbesondere kann das erste Fixierelement am Kabelbaumstecker angeordnet sein.The first fixing element is used for direct attachment of the harness connector at the interface or on the interface collar. In this case, the first fixing element may also be referred to as a plug lock. For example, the first fixing element can be manually operated. After connecting the harness connector to the interface, that is, after inserting the harness connector into the interface socket, the first fixing member can be actuated and the harness connector at the interface or on the interface socket form and possibly fix non-positively. For this purpose, for example, be provided on the outside of the interface socket two opposite, perpendicular to the insertion direction of the harness connector locking bolt. The first fixing element can be designed as a sliding element or as a rotatably mounted lever element. In particular, the first fixing element can be arranged on the harness connector.

Das zweite Fixierelement dient der direkten oder indirekten Befestigung des Kabelbaumsteckers und/oder der elektrischen Leitung am Aggregat. Insbesondere können sowohl der Kabelbaumstecker als auch die elektrische Leitung durch das zweite Fixierelement am Aggregat fixiert sein. Alternativ kann lediglich eines dieser Elemente am Aggregat fixiert sein. Die Fixierung kann dabei formschlüssig oder sowohl form- als auch kraftschlüssig sein. Beispielsweise kann die Befestigung durch das zweite Fixierelement in einem vorgegebenen Abstand von der Schnittstelle stattfinden. Beispielsweise kann der vorgegebene Abstand kleiner als 100 mm, insbesondere keiner als 50 mm und vorzugsweise kleiner als 30 mm sein.The second fixing element is used for direct or indirect attachment of the harness connector and / or the electrical line to the unit. In particular, both the harness connector and the electrical line can be fixed by the second fixing element on the unit. Alternatively, only one of these elements can be fixed to the unit. The fixation can be positive or both positive and non-positive. For example, the attachment may take place by the second fixing element at a predetermined distance from the interface. For example, the predetermined distance may be less than 100 mm, in particular none than 50 mm and preferably less than 30 mm.

Das zweite Fixierelement fixiert die elektrische Leitung und/oder den Kabelbaumstecker parallel zur Steckrichtung des Kabelbaumsteckers. Das heißt, eine Bewegung in oder gegen die Steckrichtung wird verhindert. Die Steckrichtung kann dabei parallel zu einer Längsachse des Kabelbaumsteckers verlaufen. Das zweite Fixierelement kann ähnlich zum ersten Fixierelement ausgeführt sein. Dabei kann das zweite Fixierelement manuell anbringbar und manuell betätigbar ausgeführt sein.The second fixing element fixes the electrical line and / or the harness connector parallel to the insertion direction of the harness connector. That is, a movement in or against the insertion direction is prevented. The plug-in direction can run parallel to a longitudinal axis of the harness connector. The second fixing element may be similar to the first fixing element be executed. In this case, the second fixing element can be made manually attachable and manually operable.

Das zweite Fixierelement kann nach dem Verbinden des Kabelbaumsteckers mit der Schnittstelle und nach oder vor dem Schließen des ersten Fixierelements betätigt werden. Dabei kann das zweite Fixierelement bereits am Kabelbaumstecker montiert oder als separates Bauelement ausgeführt sein. Ferner kann das zweite Fixierelement als Schiebeelement oder als drehbar gelagertes Hebelelement ausgeführt sein.The second fixing element can be actuated after connecting the harness connector with the interface and after or before closing the first fixing element. In this case, the second fixing element can already be mounted on the harness connector or be designed as a separate component. Furthermore, the second fixing element can be designed as a sliding element or as a rotatably mounted lever element.

Gemäß einem Ausführungsbeispiel der Erfindung ist das zweite Fixierelement als Schnellverschluss ausgeführt. Der Schnellverschluss kann dabei als manuell betätigbarer Hebel- oder Schiebeverschluss ausgeführt und mehrmals lösbar sein. Ferner kann der Schnellverschluss als Einrastverschluss ausgeführt sein. Des Weiteren kann der Schnellverschluss federbeaufschlagt sein und nach dem Schließen durch die Feder in der geschlossenen Position gehalten werden. Ferner kann der Schnellverschluss nach Betätigung automatisch schließen. Optional kann auch das erste Fixierelement als Schnellverschluss ausgeführt sein.According to one embodiment of the invention, the second fixing element is designed as a quick release. The quick release can be designed as a manually operable lever or sliding closure and be solvable several times. Furthermore, the quick release can be designed as a snap closure. Furthermore, the quick release may be spring biased and held closed by the spring in the closed position. Furthermore, the quick release after operation can close automatically. Optionally, the first fixing element can be designed as a quick release.

Durch die Verwendung eines Schnellverschlusses kann die Montagezeit des Kabelbaums an der Schnittstelle erheblich reduziert werden. Ferner kann bei der Montage auf den Einsatz von zusätzlichen Werkzeugen, wie Schraubenzieher, verzichtet werden. Hierdurch kann der im Fahrzeug benötigte Montageraum reduziert werden.By using a quick release, the assembly time of the wiring harness at the interface can be significantly reduced. Furthermore, during installation, the use of additional tools, such as screwdrivers, can be dispensed with. As a result, the mounting space required in the vehicle can be reduced.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist am Aggregat ein Verriegelungselement vorgesehen. Das zweite Fixierelement ist dabei ausgeführt, mit dem Verriegelungselement derart formschlüssig einzugreifen, das das zweite Fixierelement formschlüssig am Aggregat fixiert ist. Das Verriegelungselement kann zum Beispiel als einer oder mehrere Bolzen, Rasthacken oder Vorsprünge ausgeführt sein. Das zweite Fixierelement kann zum Beispiel einen Hacken aufweisen, der das Verriegelungselement hintergreift.According to a further embodiment of the invention, a locking element is provided on the unit. The second fixing element is designed to interlock with the locking element in such a form-fitting manner that the second fixing element is fixed in a form-fitting manner to the unit. The locking element may be embodied, for example, as one or more bolts, detents or projections. The second fixing element may, for example, have a hook, which engages behind the locking element.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist das Verriegelungselement in Form von zwei gegenüberliegenden senkrecht zur Steckrichtung von dem Aggregat wegweisenden Verriegelungsbolzen ausgeführt.According to a further embodiment of the invention, the locking element in the form of two opposite to the perpendicular Plug-in direction of the unit pioneering locking bolt executed.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist das zweite Fixierelement am Kabelbaumstecker angeordnet. Ferner ist das zweite Fixierelement drehbar um eine Drehachse, die senkrecht zur Steckrichtung durch den Kabelbaustecker verläuft, gelagert. Bei dieser Ausführungsform ist das zweite Fixierelement nicht separat vom Kabelbaumstecker ausgeführt, sondern an diesem vormontiert. Bei diesem Ausführungsbeispiel kann lediglich der Kabelbaumstecker durch das zweite Fixierelement direkt am Aggregat fixiert werden.According to a further embodiment of the invention, the second fixing element is arranged on the harness connector. Furthermore, the second fixing element is rotatable about an axis of rotation which runs perpendicular to the direction of insertion through the cable connector. In this embodiment, the second fixing element is not performed separately from the harness connector, but preassembled on this. In this embodiment, only the harness connector can be fixed by the second fixing directly to the unit.

Wird zum Beispiel ein Hebel auf der vom Aggregat abgewandten Seite des zweiten Fixierelements betätigt, so dreht sich das zweite Fixierelement um die Drehachse am Kabelbaumstecker. Dabei greift ein Hacken des zweiten Fixierelements hinter ein Verriegelungselement bzw. hinter einen Vorsprung am Aggregat und fixiert auf diese Weise den Kabelbaumstecker und ggf. auch die elektrische Leitung am Aggregat. Alternativ kann das zweite Fixierelement als Schieber ausgeführt sein, der in einer Ebene senkrecht zur Stechrichtung verschoben wird.If, for example, a lever is actuated on the side of the second fixing element facing away from the unit, then the second fixing element rotates about the axis of rotation at the cable harness connector. In this case, a hacking of the second fixing element engages behind a locking element or behind a projection on the unit and fixed in this way the harness connector and possibly also the electrical line to the unit. Alternatively, the second fixing element may be designed as a slide which is displaced in a plane perpendicular to the lancing direction.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist das zweite Fixierelement als separates Bauelement ausgeführt. Das zweite Fixierelement weist dabei einen Grundkörper und einen Drehkörper auf. Der Drehkörper ist relativ zum Grundkörper bewegbar ausgeführt. Insbesondere kann der Drehkörper einen Betätigungshebel und einen Einrasthaken aufweisen. Dabei kann das zweite Fixierelement separat vom Kabelbaumstecker gefertigt sein. Vor der Montage ist das zweite Fixierelement weder am Aggregat noch am Kabelbaumstecker angeordnet.According to a further embodiment of the invention, the second fixing element is designed as a separate component. The second fixing element has a base body and a rotary body. The rotary body is designed to be movable relative to the main body. In particular, the rotary body can have an actuating lever and a latching hook. In this case, the second fixing element can be manufactured separately from the harness connector. Before assembly, the second fixing element is arranged neither on the unit nor on the harness connector.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist der Grundkörper ein erstes Eingriffselement auf. Der Kabelbaumstecker weist ferner ein Aufnahmeelement auf. Das erste Eingriffselement greift formschlüssig mit dem Aufnahmeelement ein, wenn das zweite Fixierelement am Aggregat fixiert ist.According to a further embodiment of the invention, the base body has a first engagement element. The harness connector further includes a receptacle. The first engagement element engages positively with the receiving element when the second fixing element is fixed to the unit.

Das Aufnahmeelement kann zum Beispiel als eine Ausbuchtung, eine Ausnehmung oder als eine Vertiefung am Kabelbaumstecker ausgeführt sein. Das erste Eingriffselement kann als Vorsprung oder Erhebung am Grundkörper ausgeführt sein. Die Form des Eingriffselements entspricht dabei der Form des Aufnahmeelements. Bei der Montage wird das erste Eingriffselement des Grundkörpers in das Aufnahmeelement eingeführt bevor das Fixierelement betätigt wird. Auf diese Weise kann ein sicherer Sitz des separat ausgeführten zweiten Fixierelements am Kabelbaumstecker sichergestellt werden.The receiving element may be designed, for example, as a bulge, a recess or a recess on the harness connector. The first engagement element can be designed as a projection or elevation on the base body. The shape of the engagement element corresponds to the shape of the receiving element. During assembly, the first engagement element of the base body is inserted into the receiving element before the fixing element is actuated. In this way, a secure fit of the separately executed second fixing element can be ensured at the harness connector.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist der Grundkörper ferner ein zweites Eingriffselement auf. Das Aggregat weist ein Andrückelement auf. Dabei drückt das zweite Eingriffselement die elektrische Leitung gegen das Andrückelement, wenn das zweite Fixierelement am Aggregat fixiert ist.According to a further embodiment of the invention, the base body also has a second engagement element. The unit has a pressure element. In this case, the second engagement element presses the electrical line against the pressure element when the second fixing element is fixed to the unit.

Das Andrückelement kann zum Beispiel als Erhebung bzw. als Vorsprung am Aggregat ausgeführt sein. Das zweite Eingriffselement kann ähnlich zum ersten Eingriffselement als Erhebung oder Vorsprung ausgeführt sein. Bei der Montage wird das separat ausgeführte zweite Fixierelement mit dem ersten Eingriffselement in das Aufnahmeelement am Kabelbaumstecker eingeführt. Ferner drückt das zweite Eingriffselement die elektrische Leitung gegen das Andrückelement. Auf diese Weise werden sowohl die elektrische Leitung als auch der Kabelbaumstecker direkt am Aggregat fixiert. Sowohl das zweite Eingriffselement als auch das Andrückelement können eine raue bzw. geriffelte Oberfläche aufweisen, um ein Wegrutschen der Leitung zu verhindern.The pressure element can be designed, for example, as a survey or as a projection on the unit. The second engagement element may be performed similarly to the first engagement element as a survey or projection. During assembly, the separately executed second fixing element is introduced with the first engagement element in the receiving element on the harness connector. Furthermore, the second engagement element presses the electrical line against the pressure element. In this way, both the electrical line and the harness connector are fixed directly to the unit. Both the second engagement element and the pressure element may have a rough or grooved surface to prevent slippage of the line.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist der Grundkörper ausgeführt, die Leitung aufzunehmen. Der Drehkörper fixiert das zweite Fixierelement und die im Grundkörper aufgenommene Leitung formschlüssig am Aggregat, wenn das zweite Fixierelement am Steckersystem montiert ist.According to a further embodiment of the invention, the base body is designed to receive the line. The rotary body fixes the second fixing element and the line accommodated in the main body in a form-fitting manner on the unit when the second fixing element is mounted on the plug system.

Bei diesem Ausführungsbeispiel kann das zweite Fixierelement separat von den Komponenten des Steckersystems ausgeführt sein. Dabei kann lediglich die elektrische Leitung durch das zweite Fixierelement direkt am Aggregat fixiert werden. Die Innenoberfläche des Grundkörpers, in dem die elektrische Leitung aufgenommen wird, kann rau ausgeführt sein um ein Verrutschen der Leitung zu verhindern. Beispielsweise kann die Innenoberfläche des Grundkörpers geriffelt ausgeführt sein.In this embodiment, the second fixing member may be configured separately from the components of the connector system. In this case, only the electrical line can be fixed by the second fixing directly on the unit. The inner surface of the base body, in which the electrical line is accommodated, can be designed to be rough in order to prevent the cable from slipping prevent. For example, the inner surface of the body can be made corrugated.

Bei der Montage wird nach dem Herstellen einer Verbindung zwischen der Schnittstelle und dem Kabelbaumstecker das zweite Fixierelement über die elektrische Leitung derart geschoben, dass die elektrische Leitung im Grundkörper aufgenommen ist. Anschließend wird das zweite Fixierelement gegen das Aggregat bzw. ein Andrückelement gedrückt. Ferner wird der Drehkörper des zweiten Fixierelements gegen den Grundkörper so verschoben, dass das zweite Fixierelement mit einem Verriegelungselement am Aggregat eingreift und einen Formschluss herstellt. Die Bewegung des Drehkörpers kann eine Translations- und/oder eine Rotationsbewegung umfassen.During assembly, after establishing a connection between the interface and the harness connector, the second fixing member is slid over the electric wire so that the electric wire is received in the main body. Subsequently, the second fixing element is pressed against the unit or a pressing element. Further, the rotary body of the second fixing element is moved against the base body so that the second fixing element engages with a locking element on the unit and produces a positive connection. The movement of the rotary body may comprise a translatory and / or a rotational movement.

Gemäß einem zweiten Aspekt der Erfindung wird ein Verfahren zum Herstellen eines oben beschriebenen Steckersystems für Hochstromsteckverbindungen vorgestellt. Das Verfahren weist die folgenden Schritte auf: Bereitstellen eines Kabelbaumsteckers mit einer elektrischen Leitung; Bereitstellen eines Aggregats mit einer Schnittstelle zur Herstellung einer elektrischen Verbindung zwischen dem Kabelbaumstecker und dem Aggregat; formschlüssiges Fixieren des Kabelbausteckers an der Schnittstelle mittels eines ersten Fixierelements; formschlüssiges Fixieren des Kabelbaumsteckers und/oder der Leitung mittels eines zweiten Fixierelements derart am Aggregat, dass eine Bewegung des Kabelbaumsteckers und/oder der Leitung parallel und gegebenenfalls gleichzeitig auch senkrecht zu einer Steckrichtung des Kabelbaumsteckers unterbunden ist.According to a second aspect of the invention, a method for manufacturing a plug-in system for high-current plug connections described above is presented. The method comprises the following steps: providing a harness connector with an electrical lead; Providing an aggregate having an interface for establishing an electrical connection between the harness connector and the aggregate; positive locking of the cable connector at the interface by means of a first fixing element; positively fixing the harness connector and / or the line by means of a second fixing member such on the unit that a movement of the harness connector and / or the line is parallel and optionally simultaneously prevented perpendicular to a direction of insertion of the harness connector.

Dabei kann das erste Fixierelement 11 als Verriegelungshebel zwischen dem Kabelbaumstecker 3 und der Schnittstelle 9 ausgeführt sein. Das erste Fixierelement 11 befestigt spielfrei, formschlüssig und ggf. kraftschlüssig den Kabelbaustecker 3 an der Schnittstelle 9. Hierzu können an der Schnittstelle 9 bzw. am Außenumfang der Schnittstellenbuchse senkrecht zur Steckrichtung 15 von der Schnittstelle 9 wegweisende Verriegelungsbolzen vorgesehen sein, mit denen das erste Fixierelement 11 nach Betätigung des Hebels zum Beispiel mittels eines Einrasthakens eingreift.At the harness connector 3, a first fixing member 11 is provided. The first fixing element 11 may be rotatably mounted about an axis on the harness connector 3. In this case, the first fixing element 11 may be designed as a locking lever between the harness connector 3 and the interface 9.

In Fig. 1 sind unterschiedliche Positionen bzw. Schließzustände des Steckersystems 1 gemäß einem ersten Ausführungsbeispiel dargestellt. Fig. 1A zeigt das Steckersystem 1 in Ansetzposition ohne das zweite Fixierelement 13. Der Kabelbaumstecker 3 ist dabei am Aggregat 7 geführt und gegenüber der Schnittstelle 9 angeordnet. Die elektrischen Kontaktelemente der Schnittstelle 9 und des Kabelbaumsteckers 3 sind jedoch noch nicht in elektrischem Kontakt. Ferner befindet sich das erste Fixierelement 11 in einer offenen Position. Am Aggregat 7 sind Vorsprünge vorgesehen, an denen der Kabelbaumstecker 3 und die elektrische Leitung 5 ausgerichtet und positioniert werden können. Diese können auch eine Anschlussgeometrie für das zweite Fixierelement 13 bereitstellen.In Fig. 1 different positions or closing states of the connector system 1 are shown according to a first embodiment. Fig. 1A shows the connector system 1 in Ansetzposition without the second fixing element 13. The harness connector 3 is guided on the unit 7 and arranged opposite the interface 9. However, the electrical contact elements of the interface 9 and the harness connector 3 are not yet in electrical contact. Further, the first fixing member 11 is in an open position. On the unit 7 projections are provided, in which the harness connector 3 and the electrical line 5 can be aligned and positioned. These can also provide a connection geometry for the second fixing element 13.

In Fig. 1B sind der Kabelbaumstecker 3 und der Schnittstellenkragen zusammengesteckt. Das heißt, die Steckverbindung ist geschlossen. Ferner ist das erste Fixierelement 11 geschlossen, so dass der Kabelbaumstecker 3 spielfrei mit der Schnittstelle 9 verbunden ist. Das separat von den Komponenten des Steckersystems ausgeführte zweite Fixierelement 13 ist offen und befindet sich in einer Ansetzposition.In Fig. 1B the harness connector 3 and the interface collar are plugged together. That is, the connector is closed. Further is the first fixing member 11 is closed, so that the harness connector 3 is connected without play with the interface 9. The second fixing element 13, which is separate from the components of the plug system, is open and is in a fitting position.

Dabei ist das zweite Fixierelement 13 im Gegensatz zu Fig. 1 und 3 bei diesem Ausführungsbeispiel am Kabelbaumstecker 3 vormontiert und um eine Drehachse 19 drehbar gelagert. Ferner weist das zweite Fixierelement 13 bei dieser Ausgestaltung im Gegensatz zu den Ausgestaltungen von Fig. 1 und 3 keinen Grundkörper, sondern lediglich einen direkt am Kabelbaumstecker montierten Drehkörper auf. In Fig. 2A ist die Steckerverbindung offen und befindet sich ähnlich zu Fig. 1A in Ansetzposition. Sowohl das erste Fixierelement 11 als auch das zweite Fixierelement 13 sind in einer offenen Position.In Fig. 2 different positions or closing states of the plug system 1 according to a second embodiment are shown.
