Description

Beschreibung  description
Elektrische Verbindung Electrical connection
Stand der Technik State of the art
Die Erfindung betrifft eine elektrische Verbindung nach dem Oberbegriff des Anspruchs 1. The invention relates to an electrical connection according to the preamble of claim 1.
Eine derartige elektrische Verbindung ist bereits allgemein bekannt und dient bei elektrischen Geräten, beispielsweise bei Steuergeräten oder Aggregaten in der Kraftfahrzeugtechnik, zum elektrischen Verbinden eines Anschlussdrahtes mit einem Steckkontaktelement. Hierbei wird üblicherweise eine kraftschlüssige Verbindung in Form einer sogenannten Crimpverbindung eingesetzt. Bei einer Crimpverbindung werden Anschlussbereiche des Steckkontaktelements durch plastische Verformung mit dem Anschlussdraht verbunden. Eine derartige Crimpverbindung ist nur bedingt lösbar und meist nicht reparabel. Such an electrical connection is already well known and used in electrical devices, such as control units or units in automotive technology, for electrically connecting a lead wire with a plug contact element. In this case, a frictional connection in the form of a so-called crimp connection is usually used. In a crimp connection, connection regions of the plug-in contact element are connected to the connection wire by plastic deformation. Such a crimp connection is only partially solvable and usually not repairable.
Darüber hinaus sind Steckverbindungen bekannt, welche ein Steckkontaktelement und ein Gegensteckerkontakt aufweisen. Diese beiden Elemente werden ebenfalls durch Kraftschluss bzw. Federwirkung miteinander verbunden, wobei eine derartige Verbindung beliebig oft lösbar und reparabel ist. In addition, plug connections are known, which have a plug-in contact element and a mating plug contact. These two elements are also connected to each other by adhesion or spring action, such a connection as often as is solvable and reparable.
Nachteilig bei beiden kraftschlüssigen Verbindungen ist, dass bei sehr kleinen elektrischen Strömen, gemeint sind hier insbesondere Ströme im Bereich von Nanoampere oder darunter, die Kontaktstellen der Verbindung ein nichtlineares Widerstandsverhalten aufweisen. Dieses nichtlineare Widerstandsverhalten ändert die elektrische Information, die durch die elektrische Verbindung möglichst unverändert weitergeleitet werden soll. Offenbarung der Erfindung A disadvantage of both non-positive connections is that for very small electrical currents, meaning in particular currents in the range of nanoamps or below, the contact points of the compound have a non-linear resistance behavior. This non-linear resistance behavior changes the electrical information, which should be forwarded as unchanged as possible by the electrical connection. Disclosure of the invention
Ausgehend von dem dargestellten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine elektrische Verbindung nach dem Oberbegriff des An- spruchs 1 derart weiterzubilden, dass die elektrische Verbindung auch beim Leiten von sehr geringen Strömen ein möglichst lineares Widerstandsverhalten aufweist. Diese Aufgabe wird bei einer elektrischen Verbindung mit den Merkmalen des Anspruchs 1 erfindungsgemäß dadurch gelöst, dass zusätzlich zu der kraftschlüssigen Verbindung diese eine weitere, stoffschlüssige Verbindung aufweist. Man macht sich daher den Vorteil einer relativ einfachen Montage, wie diese bei einer kraftschlüssigen Verbindung in der Regel vorhanden ist, zunutze, und ändert bzw. modifiziert die kraftschlüssige Verbindung anschließend durch eine zusätzliche stoffschlüssige Verbindung, die eine gleichbleibend optimale Leitfähigkeit des Stromes auch bei sehr geringen Strömen gewährleistet. Based on the illustrated prior art, the invention has the object, an electrical connection according to the preamble of claim 1 further develop such that the electrical connection even when conducting very low currents as linear as possible resistance behavior. This object is achieved according to the invention in an electrical connection with the features of claim 1, that in addition to the non-positive connection, this has a further, cohesive connection. One therefore makes use of the advantage of a relatively simple assembly, as is usually the case with a non-positive connection, and then modifies or modifies the non-positive connection by an additional cohesive connection, which ensures a consistently optimal conductivity of the current even at very high ensured low currents.
Vorteilhafte Weiterbildungen der erfindungsgemäßen elektrischen Verbindung sind in den Unteransprüchen angegeben. In den Rahmen der Erfindung fallen sämtliche Kombinationen aus zumindest zwei von in den Ansprüchen, der Beschreibung und/oder den Figuren offenbarten Merkmalen. Advantageous developments of the electrical connection according to the invention are specified in the subclaims. All combinations of at least two of the features disclosed in the claims, the description and / or the figures fall within the scope of the invention.
In einer vorteilhaften Weiterbildung der Erfindung ist es vorgesehen, dass die stoffschlüssige Verbindung als Schweiß- oder Lötverbindung ausgebildet ist. Hierbei kommt als Schweißverbindung insbesondere eine Widerstands-, Ultraschall-, oder Laserschweißverbindung in Frage. Jede der genannten stoffschlüs- sigen Verbindungen lässt sich großtechnisch, je nach Anwendungsfall, mit relativ einfachen Mitteln realisieren und prozesstechnisch gut überwachen. In an advantageous embodiment of the invention, it is provided that the cohesive connection is designed as a welded or soldered connection. Here comes as a welded connection in particular a resistance, ultrasonic, or laser welding in question. Depending on the application, each of the above-mentioned material-based compounds can be realized on a large scale with relatively simple means and monitored well in terms of process technology.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist es vorgesehen, dass die Crimpverbindung als Doppelcrimpverbindung ausgebildet ist. Hierbei wird der Crimpbereich in zwei unterschiedliche Crimpstellen unterteilt, wovon die eine Crimpstelle zum kraftschlüssigen Verbinden des Steckkontaktelements mit der Litze eines Anschlussdrahtes dient, während die andere Crimpstelle der e- lektrischen Kontaktierung des Anschlussdrahtes selbst dient, wobei dieser Bereich von der Litze abisoliert bzw. befreit ist. Dadurch wird insbesondere bei einer Zugbeanspruchung eine Zugentlastung auf den der elektrischen Kontaktierung dienenden Anschlussdraht bewirkt. In einer ganz besonders bevorzugten Ausgestaltung der Erfindung ist es vorgesehen, dass das Steckkontaktelement mit einem Gegensteckerkontaktelement elektrisch kontaktiert und mit diesem kraftschlüssig verbunden ist und, dass zwischen dem Steckkontaktelement und dem Gegensteckerkontaktelement eine weitere zusätzliche stoffschlüssige Verbindung ausgebildet ist. Dadurch eignet sich die elektrische Verbindung z.B. zum Verbinden eines elektrischen Gerätes mit einem Anschlusskabel, z.B. dem Anschlusskabel eines Kabelbaumes in einem Kraftfahrzeug. Hierbei wird durch die weitere zusätzliche stoffschlüssige Verbindung zwischen dem Steckkontaktelement und dem Gegensteckerkontakt- element auch an dieser Stelle die Übertragung besonders kleiner Stromstärken ohne Informationsverlust ermöglicht. In a further advantageous embodiment of the invention, it is provided that the crimp connection is designed as a double crimp connection. Here, the crimping area is divided into two different crimping points, of which one crimping point is used for non-positive connection of the plug-in contact element to the stranded wire of one connecting wire, while the other crimping point serves for the electrical contacting of the connecting wire itself, this area being stripped or stripped of the stranded wire is. As a result, in particular in the case of a tensile stress, a strain relief is effected on the connection wire serving for the electrical contacting. In a very particularly preferred embodiment of the invention, it is provided that the plug-in contact element is electrically contacted with a mating plug contact element and positively connected thereto, and that between the plug contact element and the mating plug contact element, a further additional cohesive connection is formed. As a result, the electrical connection is suitable, for example, for connecting an electrical device to a connecting cable, for example the connecting cable of a cable harness in a motor vehicle. In this case, the transfer of particularly small currents without loss of information is made possible by the additional additional cohesive connection between the plug contact element and the mating plug contact element at this point.
Wie bei der ersten stoffschlüssigen Verbindung ist auch die weitere zusätzliche stoffschlüssige Verbindung bevorzugt als Schweiß- oder Lötverbindung ausge- bildet. As with the first cohesive connection, the additional additional cohesive connection is preferably designed as a welded or soldered connection.
Um einerseits eine geschützte Anordnung der elektrischen Verbindung im Bereich des Steckkontaktelements mit dem Gegensteckerkontaktelement zu ermög liehen, und andererseits die zusätzliche stoffschlüssige Verbindung auf relativ einfache Art und Weise ausbilden zu können, ist es in einer weiteren Ausgestaltung der Erfindung vorgesehen, dass das Steckkontaktelement in einem Steckergehäuse angeordnet ist und, dass das Steckergehäuse in einem Verbindungsbereich zwischen dem Steckkontaktelement und einem Gegensteckerkontaktelement eine Öffnung, insbesondere einen Durchbruch aufweist, derart, dass der Verbindungsbereich von außen zugänglich ist. In order on the one hand a protected arrangement of the electrical connection in the region of the plug contact element to the mating plug contact element made possible, and on the other hand to train the additional cohesive connection in a relatively simple manner, it is provided in a further embodiment of the invention that the plug contact element in a Plug housing is arranged and that the plug housing in a connection region between the plug contact element and a mating plug contact element has an opening, in particular an opening, such that the connection region is accessible from the outside.
Besonders bevorzugt ist es hierbei vorgesehen, wenn das Steckergehäuse mit seinem Verbindungsbereich mit den in einem Gehäuse insbesondere eines elekt rischen Geräts angeordneten Gegensteckerkontaktelementen elektrisch kontak- tierbar ist und, dass das Gehäuse eine Aussparung aufweist, die in zumindest teilweiser Überdeckung mit der Öffnung angeordnet ist und die mittels eines Deckelelements verschließbar ist. Dadurch wird eine dichte und geschützte Anordnung des Verbindungsbereichs zwischen Steckkontaktelement und Gegensteckerkontaktelement in einem Gehäuse eines elektrischen Geräts ermöglicht. Um die Prozesssicherheit insbesondere im großserientechnischen Einsatz der Erfindung weiter zu verbessern ist es darüber hinaus vorteilhaft, wenn das dem Steckergehäuse zugeordnete Steckkontaktelement in dem Steckergehäuse durch eine Formschlussverbindung, insbesondere durch eine Rastverbindung, fixiert ist. Dadurch lässt sich das Steckkontaktelement auf rein mechanischem Weg sicher mit dem Steckergehäuse verbinden und sichern. In this case, it is particularly preferred if the plug housing is electrically contactable with its connection region with the mating plug contact elements arranged in a housing, in particular of an electrical device, and that the housing has a cutout which is arranged in at least partial coverage with the opening and which can be closed by means of a cover element. As a result, a sealed and protected arrangement of the connection region between plug contact element and mating plug contact element in a housing of an electrical device is made possible. In order to further improve process reliability, in particular in the large-scale technical use of the invention, it is furthermore advantageous if the plug contact housing associated plug contact element in the plug housing by a positive connection, in particular by a latching connection, is fixed. As a result, the plug-in contact element can be securely connected to the plug housing in a purely mechanical way and secured.
Eine besonders dichte Verbindung lässt sich darüber hinaus erzielen, wenn das Steckergehäuse eine Dichtung aufweist und mit dem Gehäuse des elektrischen Geräts zusammenwirkt. A particularly tight connection can also be achieved if the plug housing has a seal and cooperates with the housing of the electrical device.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung. Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing.

In der Fig. 1 ist eine elektrische Leitung in Form eines Anschlussdrahtes 1 (Lit- zenleitung) dargestellt, die mit einem Steckkontaktelement in Form eines Steckeranschlusskörpers 10 elektrisch kontaktiert ist. Der Anschlussdraht 1 weist eine Isolation 2 auf, die die Litzendrähte 5 umschließt. Der Anschlussdraht 1 ist im Bereich seiner elektrischen Verbindung mit dem Steckeranschlusskörper 5 elektrisch abisoliert, d.h. von seiner Isolation 2 befreit. 1 shows an electrical line in the form of a lead wire 1 (lead line), which is electrically contacted with a plug contact element in the form of a plug connection body 10. The connecting wire 1 has an insulation 2, which encloses the stranded wires 5. The connecting wire 1 is electrically stripped in the region of its electrical connection to the plug connection body 5, i. freed from his isolation 2.
Der Steckeranschlusskörper 10 ist, wie an sich bekannt, als Stanz-/Biegeteil aus Blech hergestellt und weist zwei voneinander in Längsrichtung beabstandete Crimpbereiche 12, 13 auf. Hierbei dient der erste Crimpbereich 12 der kraftschlüssigen Verbindung des Steckeranschlusskörpers 10 mit der Isolation 2 nahe dem abisolierten Anschlussdraht 1 , während der zweite Crimpbereich 13 der kraftschlüssigen Verbindung des Anschlussdrahtes 1 mit dem Steckeranschlusskörper 10 dient. Wie man insbesondere anhand der Fig. 2 erkennt, weist der Steckeranschlusskörper 10 auf der den beiden Crimpbereichen 12, 13 gegenüberliegenden Seite noch eine durch einen Stanz-/Biegeprozess hergestellte, von dem eigentlichen Steckeranschlusskörper 10 abstehende Verrastungsnase 14 auf. The plug connection body 10 is, as is known per se, produced as a stamped / bent part from sheet metal and has two crimp regions 12, 13 which are spaced apart from one another in the longitudinal direction. Here, the first crimping area 12 of the non-positive connection of the connector body 10 with the insulation 2 near the stripped terminal wire 1, while the second crimping area 13 of the non-positive connection of the lead wire 1 with the connector body 10 is used. As can be seen in particular with reference to FIG. 2, the plug connection body 10 on the side opposite the two crimp regions 12, 13 still has a latching nose 14 produced by a stamping / bending process and protruding from the actual plug connection body 10.
Erfindungsgemäß ist es vorgesehen, dass der zweite Crimpbereich 13, der der elektrischen Kontaktierung des Anschlussdrahtes 5 mit dem Steckeranschluss- körper 10 dient, mit einer zusätzlichen stoffschlüssigen Verbindung 15 ausgestattet bzw. versehen ist. Hierbei ist die zusätzliche stoffschlüssige Verbindung 15 insbesondere als Schweißverbindung ausgebildet. Als Schweißverbindung kommt dabei, je nach Anwendungsfall, insbesondere eine Laser-, Widerstandsoder Ultraschallschweißung in Frage. Alternativ ist auch eine Lötverbindung denkbar. According to the invention, it is provided that the second crimping region 13, which serves to electrically contact the connecting wire 5 with the plug connection body 10, is equipped or provided with an additional cohesive connection 15. Here, the additional cohesive connection 15 is formed in particular as a welded connection. As a welded joint comes, depending on the application, in particular a laser, resistance or ultrasonic welding in question. Alternatively, a solder joint is conceivable.
In der Fig. 3 ist ein Steckergehäuse 20 zur Verwendung mit mehreren Steckeranschlusskörpern 10 dargestellt, die parallel nebeneinander im Steckergehäuse 20 angeordnet sind. Hierbei weist das Steckergehäuse 20 einen Durchbruch in Form einer Öffnung 21 auf, dessen eine Begrenzungswand 22 gleichzeitig alsFIG. 3 shows a plug housing 20 for use with a plurality of plug connection bodies 10, which are arranged parallel to one another in the plug housing 20. Here, the plug housing 20 has an opening in the form of an opening 21, whose one boundary wall 22 at the same time as
Anschlag für die Verrastungsnasen 14 der Steckeranschlusskörper 10 dient, so dass die Steckeranschlusskörper 10 durch Formschluss in dem Steckergehäuse 20 aufgenommen bzw. darin gesichert sind. Wesentlich ist auch, dass der Bereich der Öffnung 21 in dem Steckergehäuse 20 in einem Bereich angeordnet ist, in dem eine kraftschlüssige Verbindung mit Gegensteckern 24 (siehe Fig. 4) stattfindet. Stop for the Verrastungsnasen 14 of the connector body 10 is used, so that the plug connection body 10 are accommodated by positive engagement in the connector housing 20 and secured therein. It is also essential that the region of the opening 21 in the plug housing 20 is arranged in a region in which a frictional connection with mating plugs 24 (see FIG. 4) takes place.
In der Fig. 4 ist ein elektrisches Gerät 30, das beispielsweise eine nicht dargestellte integrierte Schaltung oder ähnliches aufweist, dargestellt. Das insbesondere in einem Kraftfahrzeug einsetzbare elektrische Gerät 30 weist ein Gehäuse 31 auf, das im Bereich der Gegenstecker 24 eine Aussparung 32 aufweist. Die Aussparung 32 ist mittels eines in der Fig. 6 dargestellten Deckelelements 33 dicht verschließbar, z.B. durch eine Laserverschweißung. Zum Fügen des Steckergehäuses 20 mit dem elektrischen Gerät 30 entsprechend der Richtung des Pfeils 34 in der Fig. 4 wird das Steckergehäuse 20 mit dem Bereich seiner Öffnung 21 in einen Gehäuseabschnitt 35 eingeführt. Um eine dichte Verbindung zwischen dem Steckergehäuse 20 und dem Gehäuseabschnitt 35 bzw. dem Gehäuse 31 zu erzielen, weist entweder der Gehäuseabschnitt 35, oder aber bevorzugt das Steckergehäuse 20 noch eine in der Fig. 3 erkennbare Dichtung 36 auf. In der Fig. 5 ist der Zustand dargestellt, bei dem das Steckergehäuse 20 vollständig in den Gehäuseabschnitt 35 des Gehäuses 31 eingeführt ist. Man erkennt insbesondere, dass die Öffnung 21 des Steckergehäuses 20 und die Aussparung 32 des Gehäuses 31 fluchtend zueinander angeordnet sind, so dass der Verbindungsbereich 37 zwischen den Steckeranschlusskörpern 10 und den Ge- gensteckern 24, in denen diese kraftschlüssig und elektrisch leitend miteinander verbunden sind, von außen her zugänglich bzw. bearbeitbar ist. Erfindungsgemäß ist es vorgesehen, dass im Verbindungsbereich 37 die einzelnen Verbindungen zwischen den jeweiligen Steckeranschlusskörpern 10 und den zugeordneten Gegensteckern 24 mit einer weiteren stoffschlüssige Verbindungen 38 ver- sehen werden. Auch diese weitere stoffschlüssige Verbindung 38 ist bevorzugt als Löt- oder Schweißverbindung ausgebildet. Im dargestellten Ausführungsbeispiel, bei der die Gegenstecker 24 innerhalb der Steckeranschlusskörper 10 angeordnet bzw. von diesen umschlossen sind, ist die zusätzliche stoffschlüssige Verbindung 38 als Laserschweißverbindung ausgebildet. Sobald die zusätzliche stoffschlüssige Verbindung 38 ausgebildet ist, wird das Gehäuse 31 mittels desIn Fig. 4 is an electrical device 30, which has, for example, an integrated circuit, not shown, or the like. The electrical device 30, which can be used in particular in a motor vehicle, has a housing 31 which has a recess 32 in the area of the mating connector 24. The recess 32 is tightly closed by means of a cover element 33 shown in FIG. 6, e.g. by a laser welding. For joining the plug housing 20 with the electrical device 30 in accordance with the direction of the arrow 34 in FIG. 4, the plug housing 20 is inserted with the region of its opening 21 in a housing section 35. In order to achieve a sealed connection between the plug housing 20 and the housing section 35 or the housing 31, either the housing section 35 or, preferably, the plug housing 20 still has a seal 36 which can be seen in FIG. 3. 5, the state is shown in which the connector housing 20 is fully inserted into the housing portion 35 of the housing 31. It can be seen in particular that the opening 21 of the plug housing 20 and the recess 32 of the housing 31 are arranged in alignment with one another, so that the connecting region 37 between the plug connection bodies 10 and the GE gensteckern 24 in which they are non-positively and electrically conductively connected to each other, is accessible or editable from the outside. According to the invention, it is provided that in the connection region 37, the individual connections between the respective plug connection bodies 10 and the associated mating plugs 24 will be provided with a further cohesive connection 38. This further cohesive connection 38 is preferably designed as a soldered or welded connection. In the illustrated embodiment, in which the mating connector 24 are disposed within the connector body 10 and enclosed by this, the additional cohesive connection 38 is formed as a laser welding connection. Once the additional cohesive connection 38 is formed, the housing 31 by means of
Deckelelements 33 verschlossen, so dass dieses nach außen hin abgedichtet ist. Die soweit beschriebene elektrische Verbindung lässt sich in vielfältiger Art und Weise modifizieren bzw. abwandeln ohne vom Erfindungsgedanken abzuweichen. So ist es beispielsweise denkbar, das Steckergehäuse 20 direkt mit Gegensteckern 24 elektrisch zu kontaktieren, ohne dass diese in einem separaten Gehäuse 31 eines elektrischen Geräts 30 angeordnet sind. In diesem Fall ist es sinnvollerweise vorgesehen, die Öffnung 21 des Steckergehäuses 20 mittels eines separaten Deckelelements zu verschließen. Lid member 33 closed so that it is sealed to the outside. The electrical connection described so far can be modified or modified in many ways without departing from the spirit of the invention. Thus, it is conceivable, for example, to contact the plug housing 20 directly with mating plugs 24 electrically, without these being arranged in a separate housing 31 of an electrical device 30. In this case, it is expediently provided to close the opening 21 of the plug housing 20 by means of a separate cover element.
