Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Kontaktpartners für einen Steckverbinder sowie einen nach diesem Verfahren hergestellten Kontaktpartner gemäß den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a method for producing a contact partner for a connector and a contact partner produced by this method according to the features of the preamble of claim 1.

Aus der DE 10 2006 014 156 ist ein Kontaktpartner für einen Steckverbinder bekannt, wobei eine auf einen Gegenkontaktpartner wirkende Druckfeder an einem Kontaktgehäuse (Halteschutzbuchse), das zur Aufnahme des Gegenkontaktpartners ausgebildet ist, angefügt ist, wobei weiterhin der Kontaktpartner an einem Ende eines Kabels angeordnet ist und ein elektrischer Leiter des Kabels elektrisch mit dem Kontaktpartner verbunden wird.From the DE 10 2006 014 156 is known a contact partner for a connector, wherein a force acting on a mating contact partner compression spring on a contact housing (retaining sleeve), which is designed to receive the mating contact partner, is attached, further wherein the contact partner is disposed at one end of a cable and an electrical conductor of the cable electrically connected to the contact partner.

Diese bekannte Halteschutzbuchse wird in der Fertigung ohne elektrischen Kontaktierungsbereich gefertigt und erst bei einem späteren Verarbeitungsprozess (folgender Verarbeitungsschritt) mit dem elektrischen Leiter für eine Steckverbindung in einem geeigneten Montagewerkzeug verbunden.This known retaining sleeve is made in manufacturing without electrical contact area and only at a later processing process (following processing step) connected to the electrical conductor for a plug-in connection in a suitable assembly tool.

Bei Bedarf einer veredelten Oberfläche im Kontaktierungsbereich muss diese Oberflächenbearbeitung nachträglich, nach dem Anfügen des elektrischen Leiters an der Halteschutzbuchse mit großem Aufwand ausgeführt werden. Das Verbinden der Halteschutzbuchse mit dem elektrischen Leiter auf einem Halb- oder Vollfertigungsautomaten wird auch durch den notwendigen vorgeschalteten Vorbereitungsprozess für die den Kontaktierungsbereich und dem anschließenden axialen Zusammenführungsprozess von Halteschutzbuchse und elektrischem Leiter zeitlich begrenzt, was sich nachteilig in der Wirtschaftlichkeit des Fertigungsprozesses auswirkt. Insbesondere ist es von Nachteil, dass das Material der Halteschutzbuchse im Regelfall sehr dünn ist, so dass die Gefahr besteht, dass bei dem Fügeprozess, mit dem der elektrische Leiter an die Halteschutzbuchse angefügt wird, aufschmilzt und somit keine zuverlässige elektrische Kontaktierung und mechanische Festlegung gegeben ist.If required, a finished surface in the contacting area, this surface treatment must be subsequently carried out after attaching the electrical conductor to the retaining sleeve with great effort. Connecting the retaining sleeve with the electrical conductor on a half or Automatic manufacturing machines are also limited in time by the necessary upstream preparation process for the contacting area and the subsequent axial merging process of retaining sleeve and electrical conductor, which has a detrimental effect on the economy of the manufacturing process. In particular, it is disadvantageous that the material of the retaining sleeve is usually very thin, so that there is a risk that in the joining process, with which the electrical conductor is attached to the retaining sleeve melts and thus given no reliable electrical contact and mechanical fixing is.

Der Erfindung liegt daher die Aufgabe zugrunde, ein verbessertes Verfahren zur Herstellung eines Kontaktpartners für einen Steckverbinder bereit zu stellen, mit dem der elektrische Leiter zuverlässig und dauerhaft an dem Kontaktpartner angefügt werden kann, ohne dass es zu zeitlichen Behinderungen bei dem Fertigungsprozess kommt.The invention is therefore based on the object to provide an improved method for producing a contact partner for a connector, with which the electrical conductor can be reliably and permanently attached to the contact partner, without causing time constraints in the manufacturing process.

Diese Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst.This object is solved by the features of claim 1.

Erfindungsgemäß ist vorgesehen, dass das Kontaktgehäuse zusätzlich mit einem Kontaktteil versehen wird, an dem der elektrische Leiter an das Kontaktgehäuse angefügt wird, wobei das Kontaktteil zur Durchführung dieses Fügeprozesses ausgebildet ist. Mit anderen Worten wird das Material des Kontaktgehäuses (Halteschutzbuchse) mit Hilfe eines zusätzlichen Kontaktteiles verstärkt, um den elektrischen Leiter mittels eines geeigneten Fügeverfahrens optimal, das heißt, dauerhaft und zuverlässig, an dem Kontaktgehäuse anfügen zu können. In das Kontaktgehäuse (die Halteschutzbuchse) wird eine kompakte und mit hoher Dichte versehene Kontaktteilzone integriert und fest verbunden, so dass bei dem anschließenden Verarbeitungsprozess eine insbesondere vertikale Zuführung des elektrischen Leiters mit einem anschließenden Fügeprozess (Schweißprozess oder andere Verbindungsmethode) die Halteschutzbuchse mit dem elektrischen Leiter verbunden werden kann. Dabei ist dieses zusätzliche Kontaktteil zur Durchführung des Fügeprozesses ausgebildet. Das heißt, dass das zusätzliche Kontaktteil einerseits so ausgebildet ist, dass es zuverlässig an dem Kontaktgehäuse angefügt werden kann und andererseits nach dem Anfügen an dem Kontaktgehäuse ein insbesondere anderer Fügeprozess eingesetzt werden kann, um den elektrischen Leiter mit dem Kontaktteil zu verbinden. Da bei diesem Fügeprozess andere Parameter, insbesondere Drücke und Temperaturen, zum Einsatz kommen, verhindert das Kontaktteil, dass durch diese Parameter das eigentliche Kontaktgehäuse beschädigt werden könnte. Wird beispielsweise das Kontaktgehäuse aus einem dünnen Blechstreifen in einem Stanzbiegeverfahren hergestellt und würde anschließend mittels eines Schweißprozesses der elektrische Leiter direkt an das Kontaktgehäuse angefügt werden, besteht die Gefahr, dass aufgrund der Parameter dieses Schweißprozesses das Kontaktgehäuse aufschmilzt und somit kein zuverlässiger Kontaktbereich der überhaupt kein Kontaktbereich mehr vorhanden ist. Durch den Einsatz des zusätzlichen Kontaktteils wird in vorteilhafter Weise der Kontaktierungsbereich für den elektrischen Leiter verstärkt (z.B. durch entsprechende Materialwahl des Kontaktteils oder entsprechende Materialdicke), so dass der gewünschte Fügeprozess, insbesondere das Schweißverfahren, weiterhin insbesondere ein Reibschweißverfahren, ausgeführt werden kann, ohne das Kontaktgehäuse (Halteschutzbuchse) zu beschädigen. Dies ist vor allen Dingen dann von Vorteil, wenn der elektrische Leiter ein Rundleiter, vorzugsweise ein Litzenleiter, ist, und vor und/oder während des Fügens an das Kontaktteil plattiert wird. Denn durch das Plattieren (Flachdrücken) mit einem entsprechenden Werkzeug zur Anfügung des elektrischen Leiters an dem Kontaktteil würde ohne ein solches Kontaktteil das Kontaktgehäuse die hierbei herrschenden Drücke bzw. Temperaturen nicht aushalten, so dass in vorteilhafter Weise das Kontaktgehäuse durch das Kontaktteil verstärkt wird und der entsprechende Fügeprozess und/oder Umformprozess ausgeführt werden kann.According to the invention, it is provided that the contact housing is additionally provided with a contact part, to which the electrical conductor is attached to the contact housing, wherein the contact part is designed to carry out this joining process. In other words, the material of the contact housing (retaining sleeve) is reinforced by means of an additional contact member to optimally attach the electrical conductor by means of a suitable joining method, that is, permanently and reliably, to the contact housing. In the contact housing (the retaining sleeve) a compact and high-density contact zone is integrated and firmly connected, so that in the subsequent processing process, in particular a vertical supply of the electrical conductor with a subsequent joining process (welding process or other connection method) the retaining sleeve can be connected to the electrical conductor. In this case, this additional contact part is designed to carry out the joining process. This means that the additional contact part is on the one hand designed so that it can be reliably attached to the contact housing and on the other hand after attaching to the contact housing a particular other joining process can be used to connect the electrical conductor to the contact part. Since other parameters, in particular pressures and temperatures, are used during this joining process, the contact part prevents the actual contact housing from being damaged by these parameters. If, for example, the contact housing is produced from a thin sheet-metal strip in a stamped bending process and the electrical conductor would then be attached directly to the contact housing by means of a welding process, there is a risk that the contact housing will melt due to the parameters of this welding process and thus no reliable contact area of no contact area at all more is available. By using the additional contact part, the contacting region for the electrical conductor is advantageously reinforced (eg by appropriate choice of material of the contact part or corresponding material thickness), so that the desired joining process, in particular the welding process, furthermore a friction welding process, can be carried out without this Contact housing (retaining sleeve) to damage. This is advantageous above all when the electrical conductor is a round conductor, preferably a stranded conductor, and is plated before and / or during the joining to the contact part. Because by the plating (flattening) with a corresponding tool for attachment of the electrical conductor to the contact part would without such Contact part of the contact housing in this case the prevailing pressures or temperatures can not withstand, so that advantageously the contact housing is reinforced by the contact part and the corresponding joining process and / or forming process can be performed.

Weitere Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben und werden anhand eines Ausführungsbeispieles, auf dass die Erfindung jedoch nicht beschränkt ist, im Folgenden beschrieben und anhand der Figuren erläutert.Further embodiments of the invention are specified in the dependent claims and will be described with reference to an embodiment, to which the invention is not limited, and explained with reference to the figures.

In den Figuren 1 und 2 ist, soweit im Einzelnen dargestellt, mit der Bezugsziffer 1 ein Kontaktpartner für einen Steckverbinder bezeichnet. Ein oder mehrere solche Kontaktpartner 1 werden in ein Steckverbindergehäuse, genauer deren Kontaktkammern, eingesetzt und bilden somit eine einreihige, mehrreihige und somit mehrpolige Steckverbindung.In the FIGS. 1 and 2 is, as far as shown in detail, the reference numeral 1 denotes a contact partner for a connector. One or more such contact partners 1 are inserted into a connector housing, more precisely their contact chambers, and thus form a single-row, multi-row and thus multi-pin connector.

Der Kontaktpartner 1 ist an dem Ende eines Kabels 2, das einen elektrischen Leiter 3 aufweist, angeordnet. Bei dem Kabel 2 handelt es sich um ein einpoliges Kabel, es kann aber auch als mehrpoliges Kabel (wie z.B. Stegleitung) ausgebildet sein. Es muss sich auch nicht zwangsweise um ein Rundkabel handeln, sondern es kann auch eine Flachbandleitung sein.The contact partner 1 is disposed at the end of a cable 2 having an electrical conductor 3. The cable 2 is a single-pole cable, but it may also be a multi-pole cable (such as a jumper line). It also does not necessarily have to be a round cable, but it can also be a ribbon cable.

Das Ende des elektrischen Leiters 3 ist an einem Kontaktgehäuse 4 (Halteschutzbuchse) dauerhaft angefügt, wobei weiterhin an dem Kontaktgehäuse 4 eine Druckfeder 5 angeordnet ist, die auf einen hier nicht dargestellten Gegenkontaktpartner zur Erzielung der entsprechenden Kontaktkräfte wirkt.The end of the electrical conductor 3 is permanently attached to a contact housing 4 (retaining sleeve), wherein further on the contact housing 4, a compression spring 5 is arranged, which acts on a mating contact partner, not shown here to achieve the corresponding contact forces.

Erfindungsgemäß ist das Kontaktgehäuse 4 mit einem zusätzlichen Kontaktteil 6 versehen, welches z.B. nur in dem Bereich, in dem der elektrische Leiter 3 mit dem Kontaktgehäuse 4 verbunden werden soll, vorhanden ist.According to the invention, the contact housing 4 is provided with an additional contact part 6, which e.g. only in the area in which the electrical conductor 3 is to be connected to the contact housing 4, is present.

Bei dem in Figur 1 gezeigten Ausführungsbeispiel erstreckt sich das zusätzliche Kontaktteil 6, ausgehend von dem Bereich, in dem der elektrische Leiter 3 vorhanden ist, bis in Richtung der Steckseite des Kontaktgehäuses 4, wobei in der mittleren Darstellung der Figur 1 erkennbar ist, dass es im steckseitigen Endbereich umgebogen ist. Durch dieses separate Bauteil in Form des Kontaktteiles 6 besteht bei Bedarf gleichzeitig die Möglichkeit, die kontaktteillose Kontaktierung in verschiedenen Oberflächenausführungen (wie z.B. Gold, Silber, Zinn usw.) extrem kostengünstig auszuführen, wobei nur eine einzige Fertigungswerkzeugvariante für das Kontaktgehäuse 4 benötigt wird, da das Kontaktteil 6 in der gewünschten Formgebung und mit dem gewünschten Material zusätzlich eingesetzt werden kann. Hierzu ist es denkbar, dass das Kontaktteil 6 mittels Kraftschluss an dem Kontaktgehäuse 4 festgelegt wird und der elektrische Leiter 3 mittels des schon erwähnten Löt- oder Schweißverfahrens, insbesondere dem Reibschweißverfahren, an dem Kontaktteil 6 angefügt wird.At the in FIG. 1 In the embodiment shown, the additional contact part 6 extends, starting from the region in which the electrical conductor 3 is present, to the direction of the plug-in side of the contact housing 4, in the middle illustration of FIG FIG. 1 It can be seen that it is bent in the plug-side end. By this separate component in the form of the contact part 6, if necessary, at the same time the possibility of contactless contact in different surface finishes (such as gold, silver, tin, etc.) to carry out extremely cost, with only a single production tool variant for the contact housing 4 is required because the contact part 6 can additionally be used in the desired shape and with the desired material. For this purpose, it is conceivable that the contact part 6 is fixed by means of frictional connection to the contact housing 4 and the electrical conductor 3 by means of the already mentioned soldering or welding process, in particular the friction welding, attached to the contact part 6.

Wenn der entsprechend der in der Figur 1 gezeigte Kontaktpartner 1 fertig hergestellt ist und der elektrische Leiter an das Kontaktteil 6 angefügt wurde, wird noch eine Dichtung 7, insbesondere eine so genannte Einzelleiterabdichtung, auf den elektrisch nicht leitfähigen Außenmantel des Kabels 2 aufgeschoben und mittels Crimpflügel 8, die vorzugsweise Bestandteil des Kontaktgehäuses 4 sind, dort mechanisch festgelegt, so dass auch eine Zugentlastung des Kontaktgehäuses 4 von auf das Kabel 2 wirkenden Zug- und Druckkräfte realisiert ist. Ein derart hergestellter und vorbereiteter Kontaktpartner 1 kann dann in eine Kontaktkammer eines hier nicht näher dargestellten Steckverbindergehäuses eingesetzt werden.If the according to the in the FIG. 1 shown contact partner 1 is finished and the electrical conductor was added to the contact part 6, is still a seal 7, in particular a so-called Einzelleiterabdichtung pushed onto the electrically non-conductive outer sheath of the cable 2 and Crimpflügel 8, preferably part of the contact housing. 4 are mechanically fixed there, so that a strain relief of the contact housing 4 is realized by acting on the cable 2 tensile and compressive forces. Such a manufactured and Prepared contact partner 1 can then be used in a contact chamber of a connector housing, not shown here.

In der Figur 1 ist die Ausführung des Fügeprozesses, mit dem der elektrische Leiter an dem Kontaktteil 6 angefügt wird, noch nicht dargestellt. Durch den punktierten Pfeil ist lediglich dargestellt, dass der elektrische Leiter 3 diesem Fügeprozess unterworfen wird und an dem Kontaktteil 6 angefügt wird. Dabei erfolgt eine Plattierung und damit einhergehend eine Kompaktierung des elektrischen Leiters 3, der hier als Litzenleiter ausgeführt ist. Dies Kompaktierung kann beispielsweise mittels eines Reibschweißverfahrens erzielt werden, so dass die geometrischen Verhältnisse nach Ausführung der Kompaktierung und des Fügens in Figur 2 dargestellt sind. Hier ist erkennbar, dass der elektrische Leiter 3 plattiert worden ist und an dem Kontaktteil 6 dauerhaft und zuverlässig angefügt wurde.In the FIG. 1 is the execution of the joining process, with which the electrical conductor is attached to the contact part 6, not yet shown. The dotted arrow merely shows that the electrical conductor 3 is subjected to this joining process and is attached to the contact part 6. In this case, a plating and, consequently, a compaction of the electrical conductor 3, which is designed here as a stranded conductor. This compaction can be achieved, for example, by means of a friction welding process, so that the geometric conditions after carrying out the compaction and the joining in FIG. 2 are shown. Here it can be seen that the electrical conductor 3 has been plated and attached to the contact part 6 permanently and reliably.

Bei Betrachtung der Figur 1, insbesondere die mittlere Darstellung, ist erkennbar, dass die Halteschutzbuchse 4, die Druckfeder 5 und das Kontaktteil 6 voneinander separate Teile sind, die auch in voneinander separaten Herstellungsschritten bzw.
Herstellungsverfahren hergestellt werden können. Dabei können gleichartige oder voneinander unterschiedliche Materialien zum Einsatz kommen. Bevorzugt werden solche Herstellungsverfahren und solche Materialien, die für den jeweiligen Zweck optimal sind. So wird vorzugsweise das Kontaktgehäuse 4 aus einem dünnen und preiswerten Blechstreifen in einem Stanzbiegeverfahren aus einem elektrisch leitfähigen Material hergestellt. Die Druckfeder 5 wird aus einem Material hergestellt, welches Federeigenschaften (wie z.B. ein Federstahl) aufweist, um dauerhaft die erforderlichen Kontaktkräfte aufbringen zu können, wenn in das Kontaktgehäuse 4 ein entsprechender Gegenkontakt eingesetzt ist. Das Kontaktteil 6 besteht, wie schon beschrieben, aus einem Material, das einerseits die erforderlichen Kontaktierungseigenschaften zwecks Kontaktierung mit dem eingesetzten Gegenkontakt aufweist und andererseits auf das Fügeverfahren, mit dem der elektrische Leiter 3 an dem Kontaktteil 6 angefügt wird, entspricht. Diese genannten beteiligten Bauelemente des Kontaktpartners 1 werden je nach Anforderungen kraftschlüssig und/oder formschlüssig miteinander verbunden. So ist es bei dem Ausführungsbeispiel, welches in den Figuren gezeigt ist, so ausgeführt, dass das Kontaktteil 6 durch Formschluss mittels verformbarer Laschen 10 und eines Steges 11 an dem Kontaktgehäuse 4 festgelegt ist. Dabei sind z.B. mittels der Laschen 10 auch die Druckfeder 5 kraftschlüssig an dem Kontaktgehäuse 4 festgelegt, wobei aber auch ein Formschluss alternativ oder ergänzend zu dem Kraftschluss zur Festlegung der Druckfeder 5 an dem Kontaktgehäuse 4 in Betracht kommt.Looking at the FIG. 1 , in particular the middle illustration, it can be seen that the retaining sleeve 4, the compression spring 5 and the contact part 6 are mutually separate parts, which are also in separate production steps or
Manufacturing process can be produced. In this case, similar or different materials can be used. Preference is given to those production methods and those materials which are optimal for the respective purpose. Thus, the contact housing 4 is preferably made of a thin and inexpensive metal strip in a stamping bending process of an electrically conductive material. The compression spring 5 is made of a material having spring properties (such as a spring steel) to permanently apply the required contact forces when in the contact housing 4, a corresponding mating contact is used. The contact part 6 consists, as already described, of a material, on the one hand the required Contacting properties for the purpose of contacting with the mating contact used and on the other hand on the joining method, with which the electrical conductor 3 is added to the contact part 6 corresponds. These mentioned components of the contact partner 1 are non-positively and / or positively connected with each other as required. So it is in the embodiment shown in the figures, carried out so that the contact part 6 is fixed by positive engagement by means of deformable tabs 10 and a web 11 on the contact housing 4. In this case, for example by means of the tabs 10 and the compression spring 5 frictionally fixed to the contact housing 4, but also a positive connection alternatively or additionally to the frictional connection for fixing the compression spring 5 to the contact housing 4 comes into consideration.

Insgesamt bietet die Erfindung also den Vorteil, dass das Kontaktgehäuse 4 schnell und einfach sowie kostengünstig hergestellt werden kann, wobei gleichzeitig auf Grund des erfindungsgemäße zusätzlichen Kontaktteils 6 sichergestellt ist, dass die mechanische Festlegung und elektrische Kontaktierung des elektrischen Leiters 3 an diesem Kontaktteil 6 dauerhaft und zuverlässig ohne Beeinträchtigungen an dem Kontaktgehäuse 4 erfolgen kann, wobei weiterhin durch das zusätzliche Kontaktteil 6 insbesondere dann die hohe Kontaktsicherheit zu einem Gegenkontakt hergestellt ist, wenn sich das Kontaktteil 6 bis in Richtung des in Richtung des in das Kontaktgehäuse 4 eingesetzten Gegenkontaktes erstreckt.Overall, the invention thus offers the advantage that the contact housing 4 can be produced quickly and easily and inexpensively, while ensuring at the same time on the basis of the additional contact part 6 according to the invention that the mechanical fixing and electrical contacting of the electrical conductor 3 at this contact part 6 permanently and Reliable can be done without adverse effects on the contact housing 4, wherein further by the additional contact part 6 in particular the high contact reliability is made to a mating contact when the contact member 6 extends in the direction of the counter contact used in the contact housing 4.
