Description

Die vorliegende Erfindung betrifft ein Kontaktsystem aus einem elektrischen Schweißkontaktelement und einem weiteren Kontaktteil sowie ein Verfahren zum Herstellen des Kontaktsystems bestehend aus dem elektrischen Schweißkontaktelement und dem weiteren Kontaktteil, insbesondere einem Flachkontakt oder einer Kontaktzunge eines Flachkontaktgitters.The present invention relates to a contact system comprising an electrical welding contact element and a further contact part as well as a method for producing the contact system consisting of the electrical welding contact element and the further contact part, in particular a flat contact or a contact tongue of a flat contact grid.

Im Stand der Technik sind eine Vielzahl von Kontaktteilen bekannt, die dazu bestimmt sind als Steckkontakt verwendet zu werden. Bei einem Steckkontakt ist wenigstens ein Bereich des Kontaktelementes als Stift oder als Federbuchse zur Aufnahme eines Gegenkontaktes ausgebildet.In the prior art, a plurality of contact parts are known, which are intended to be used as a plug contact. In the case of a plug contact, at least one region of the contact element is designed as a pin or as a spring socket for receiving a mating contact.

Aus der DE 8913569 U1 ist zum Beispiel ein Kontaktelement einteilig mit einer Überfeder ausgebildet. Eine solche Überfeder läßt sich mit dem Kontaktelement in einem Zuge als einteiliges Stanz/Biegeteil durch Stanzen und Biegen aus einem Blechstreifen herstellen, so daß eine separate Herstellung der Überfeder sowie ihre Montage und Sicherung am Basisteil entfällt. Es ist auch zu berücksichtigen, daß bei der einteiligen Herstellung Material gespart werden kann, da bei einer zweiteiligen Herstellung schon im Hinblick auf die Stanzreste mehr Material verbraucht wird.From the DE 8913569 U1 For example, a contact element is formed integrally with a spring over. Such overspring can be produced with the contact element in one go as a one-piece punched / bent part by punching and bending of a sheet metal strip, so that a separate production of the over-spring and their mounting and securing on the base part is omitted. It is also to be considered that in the one-piece production material can be saved, since in a two-part production already in view of the punching residues more material is consumed.

In diversen Anwendungen werden jedoch keine steckbaren Verbindungen benötigt, sondern dauerhafte materialschlüssige Verbindungen. Als Verbindungsverfahren kommen z.B. Schweißverfahren in Betracht, wie herkömmliche Lichtbogenschweißverfahren, Ultraschallschweißen, Laserschweißverfahren oder auch Reibschweißverfahren.In various applications, however, no pluggable connections are needed, but permanent material-locking connections. As connecting method, e.g. Welding process, such as conventional arc welding, ultrasonic welding, laser welding or friction welding.

Speziell im Automobilbereich und der Luftfahrtechnik werden hohen Anforderungen an die Genauigkeit und Reproduzierbarkeit der Verbindungsprozesse gestellt. Neben der Qualität spielen auch die Prozesskosten und die, die Prozesskosten beeinflussende Prozesssicherheit eine grundlegende Rolle. Speziell bei formschlüssigen Verbindungstechniken tritt das Problem zu Tage, dass die Kontaktpaare, die es miteinander zu verbinden gilt, in eine definierte exakte Position zueinander gebracht werden müssen und für die Dauer des Schweißprozesses ggf. mittels Halte- oder Hilfsvorrichtungen in dieser Position gehalten werden müssen. Neben dem Problem der Lageabweichung tritt ein weiteres Problem dann zu Tage, wenn die spezielle Geometrie der Kontaktpaare die Kontaktierung im Prozess weiter erschwert. So müssen zum Beispiel in der Automobilindustrie bei der Herstellung von elektrischen Verbindungen bzw. von Kabelsätzen Flachkontakte oder ganze Reihen von Flachkontakte auf korrespondierende Kontakte aufgebracht werden.Particularly in the automotive sector and in aviation technology, high demands are placed on the accuracy and reproducibility of the connection processes. In addition to quality, process costs and process reliability influencing process costs also play a fundamental role. Especially in positive connection techniques, the problem comes to light that the contact pairs, which applies it to connect with each other, must be brought into a defined exact position to each other and must be kept for the duration of the welding process, if necessary by means of holding or auxiliary devices in this position. In addition to the problem of positional deviation another problem comes to light when the special geometry of the contact pairs further complicates the contact in the process. For example, in the automotive industry in the manufacture of electrical connections or cable harnesses flat contacts or entire rows of flat contacts must be applied to corresponding contacts.

Daraus ergibt sich unter anderem die Anforderung, dass Kontaktsysteme aus mehreren Einzelteilen auszubilden sind, die es ebenfalls im Prozess zu Montieren, Halten und Bearbeiten gilt, was häufig fertigungstechnisch mit Schwierigkeiten in der Umsetzung verbunden ist, sowie aufwendig und teuer ist.Among other things, this results in the requirement that contact systems are to be formed from several individual parts which are also to be assembled in the process, Holding and processing applies, which is often associated with production engineering difficulties in the implementation, and is complicated and expensive.

Aus der DE 100 60 394 A1 ist zum Beispiel eine Vorrichtung bekannt, durch die ein Bauteilpaar fixierbar ist, um so eine Schweißverbindung mittels eines Lasers anzubringen. Hierzu ist die Vorrichtung zumindest im Spektrum des von dem Laser emittierten Lichtes transmissiv ausgeführt, so daß ein Laserstrahl durch die Vorrichtung hindurch auf das Bauteil gelangt. Daher wirkt sich auch eine großflächige Überdeckung des Bauteiles durch Auflageflächen der Vorrichtung, wie sie zur Erreichung einer optimalen Fixierung erforderlich ist, bei der Durchführung des Schweißverfahrens nicht hinderlich aus. Die Durchführung eines Schweißverfahrens erfordert ferner regelmäßig die Überwachungsmöglichkeit der Qualität der Schweißverbindung. Es ist daher wünschenswert ein Verfahren bereit zu stellen, welches eine wie zuvor beispielhaft angegebene Vorrichtung entbehrlich macht und die Problematik der Fixierung der Bauteile über eine Vorrichtung vollständig umgeht bei gleichzeitig hoher Positions- und Lagegenauigkeit und Prozesssicherheit.From the DE 100 60 394 A1 For example, a device is known by which a pair of components can be fixed so as to attach a welded joint by means of a laser. For this purpose, the device is designed to be transmissive, at least in the spectrum of the light emitted by the laser, so that a laser beam passes through the device onto the component. Therefore, a large coverage of the component by bearing surfaces of the device, as required to achieve an optimal fixation, does not interfere with the implementation of the welding process. Performing a welding process also requires regular monitoring of the quality of the welded joint. It is therefore desirable to provide a method which eliminates the need for a device as exemplified above and completely avoids the problem of fixing the components by means of a device while at the same time achieving high positional and positional accuracy and process reliability.

Ferner besteht ein Bedürfnis darin Materialpaarungen für das Kontaktsystem so zu kombinieren, dass die jeweils von dem verwendeten Bauteil gegebene Materialeigenschaft optimal genutzt werden kann. So sind typischerweise sichere und dauerhafte Verbindungen mit einem Kabel mit einem Kontaktsystem an wenigstens einer Anschlussstelle herzustellen, während andererseits die Kontaktzone eine für die Applikation geeignete Materialeigenschaften aufweisen sollte und darüber hinaus die Schweißbarkeit gewährleistet sein muß.Furthermore, there is a need to combine material pairings for the contact system in such a way that the respective material properties given by the component used can be optimally utilized. Thus, typically secure and permanent connections with a cable with a contact system to at least one connection point to produce, while on the other hand, the contact zone should have a suitable material properties for the application and beyond the weldability must be ensured.

Aufgabe der vorliegenden Erfindung ist es daher, vorbesagte Probleme und Nachteile zu überwinden und ein elektrisches Kontaktsystem aus zwei miteinander zu verbindender Kontaktteile, insbesondere aus Schweißflachkontaktteilen bereitzustellen, welches eine Hilfseinrichtung zur sicheren Halterung der Kontaktteile entbehrlich macht. Es ist ferner Aufgabe der vorliegenden Erfindung ein Verfahren zur Herstellung eines solchen Kontaktsystems bereitzustellen.Object of the present invention is therefore to overcome vorbesagte problems and disadvantages and to provide an electrical contact system of two contact parts to be joined together, in particular from Schweißflachkontaktteilen, which makes an auxiliary device for secure mounting of the contact parts dispensable. It is a further object of the present invention to provide a method for producing such a contact system.

Diese Aufgabe wird gelöst mit einem Kontaktsystem mit den Merkmalen von Anspruch 1 sowie einem Verfahren zur Herstellung eines Kontaktsystems mit den Merkmalen von Anspruch 10.This object is achieved with a contact system having the features of claim 1 and a method for producing a contact system with the features of claim 10.

Der Grundgedanke der vorliegenden Erfindung besteht darin dem eigentlichen materialschlüssigen Verbindungsprozess einen mechanischen Vorfixierprozess vorzuschalten und die miteinander zu verbindenden Kontaktelemente daher so auszubilden, dass sich das eine Kontaktelement mittels eines federnden Fixierelements am anderen Kontaktelement mit diesem zusammen in eine definierte Vormontageposition bringen lässt. Das erste Kontaktelement, vorzugsweise Flachkontaktelement wird sozusagen auf dem zweiten Kontaktelement federnd aufgebracht, so dass die miteinander zu verbindenden Schweißverbindungsabschnitte übereinander angeordnet und für den Schweißprozess zugänglich sind.The basic idea of the present invention is to precede the actual material-bonding connection process by a mechanical prefixing process and to design the contact elements to be connected so that the one contact element can be brought together by means of a resilient fixing element on the other contact element into a defined preassembly position. The first contact element, preferably a flat contact element, is so to speak resiliently applied to the second contact element, so that the welded connection sections to be connected to one another are arranged one above the other and accessible to the welding process.

Erfindungsgemäß wird daher ein elektrisches Kontaktsystem bestehend aus einem ersten Kontaktelement mit einem (vorzugsweise flachen) Schweißverbindungsabschnitt und einem zweiten Kontaktelement mit einem (vorzugsweise ebenfalls flachen) Schweißverbindungsabschnitt vorgeschlagen, um die beiden Schweißverbindungsabschnitte in berührende Anlage und materialschlüssig verbinden zu können, wobei das erste Kontaktelement benachbart zum Schweißverbindungsabschnitt ein, vorzugsweise zwei Fixierarme aufweisendes, weiter vorzugsweise U-förmig gebogenes federndes Fixierelement aufweist und zwar zum klemmenden Halten und Fixieren eines Halteabschnittes des zweiten Kontaktelementes und wobei das zweite Kontaktelement den Halteabschnitt benachbart zum Schweißverbindungsabschnitt so ausbildet, dass sich, im für den Schweißprozess vorfixierten Zustand, die beiden Schweißverbindungsabschnitte berührend gegenüberliegen.According to the invention, therefore, an electrical contact system comprising a first contact element with a (preferably flat) weld connection section and a second contact element with a (preferably likewise flat) weld connection section is proposed in order to be able to connect the two weld connection sections into touching contact and material fit, wherein the first contact element adjoins to the weld connection portion, preferably having two fixing arms, more preferably bent U-shaped fixing element for clamping holding and fixing a holding portion of the second contact element and wherein the second contact element adjacent to the weld portion forming the holding portion so that, in the for the welding process prefixed state, the two weld connection sections are touching.

Weiter bevorzugt ist es daher, eines der Kontaktelemente auf der zu verschweißenden Seite des Schweißverbindungsabschnittes mit einer Schweißkuppe zu versehen, so dass eine gezielte punktuelle Energieeinleitung erzielt werden kann.It is therefore further preferred to provide one of the contact elements on the side to be welded of the welded connection section with a welding tip, so that a targeted selective introduction of energy is achieved can be.

Erfindungsgemäß wird ferner ein solches elektrisches Kontaktsystem vorgeschlagen, bei dem die beiden Kontaktelemente materialschlüssig, vorzugsweise im Bereich der Schweißverbindungsabschnitte miteinander verbunden sind.According to the invention, such an electrical contact system is furthermore proposed in which the two contact elements are connected to one another in a material-locking manner, preferably in the region of the weld connection sections.

In einer weiter vorteilhaften Ausführungsform der Erfindung ist das elektrische Kontaktsystem so ausgebildet, dass an dem Schweißverbindungsabschnitt des ersten Kontaktelements ferner Crimpanschlußzungen oder eine Crimpanschlusskontur zum Anschluß einer Leitung einstückig mit dem Kontaktelement ausgebildet sind. Besonders vorteilhaft ist es, wenn das erste Kontaktelement einstückig mittels eines Stanz-Biege-Prozesses hergestellt wird und an dem Flachkontakt ein Crimpanschluß ausgebildet ist, wobei an der dem Crimpanschluß gegenüberliegenden Ende des Flachkontaktes das erfindungsgemäße Fixierelement ausgebildet ist.In a further advantageous embodiment of the invention, the electrical contact system is designed so that at the weld connection portion of the first contact element further Crimpanschlußzungen or a Crimpanschlusskontur are formed for connecting a line integral with the contact element. It is particularly advantageous if the first contact element is produced in one piece by means of a stamped and bent process and a crimp connection is formed on the flat contact, wherein the fixing element according to the invention is formed at the end of the flat contact opposite the crimp connection.

Weiter von Vorteil ist es, wenn der Schweißverbindüngsabschnitt des ersten Kontaktelements eine Oberseite und eine der Oberseite gegenüberliegende, als Schweißverbindungsseite ausgebildete Unterseite aufweist und/oder wenn der korrespondierende Schweißverbindungsabschnitt des zweiten Kontaktelements eine Unterseite und eine der Unterseite gegenüberliegende, als Schweißverbindungsseite entsprechend geformte Oberseite aufweist.It is further advantageous if the Schweißverbindüngsabschnitt of the first contact element has an upper side and an upper side opposite, formed as a welded joint side bottom and / or if the corresponding Schweißverbindungsabschnitt of the second contact element has a bottom and an underside opposite, designed as welded joint side corresponding upper side.

In einer besonders vorteilhaften Ausführungsform der Erfindung ragen die beiden Fixierarme aus der von dem Schweißverbindungsabschnitt gebildeten Unterseite hervor und erstrecken sich im Wesentlichen parallel zueinander von der Flachseite weg. Weiter vorteilhaft ist es, wenn sich der Crimpanschluss in die eine und das Fixiermittel in die entgegengesetzte Richtung erstrecken, so dass eine besonders vorteilhafte Montageposition erzielt werden kann.In a particularly advantageous embodiment of the invention, the two fixing arms protrude from the underside formed by the welded connection section and extend substantially parallel to one another away from the flat side. It is also advantageous if the crimp terminal extend into the one and the fixing means in the opposite direction, so that a particularly advantageous mounting position can be achieved.

In einer weiter bevorzugten Ausbildung der Erfindung weisen die beiden Fixierarme einen gerade verlaufenden Linearabschnitt auf. Weiter von Vorteil ist es, wenn die Fixierarme im Anschluss an die genannten Linearabschnitte eine Nase aufweisen bzw. durch einen Krümmungsabschnitt ausbilden, die sich in Richtung des jeweils gegenüberliegenden Fixierarms erstreckt und wobei der Abstand der beiden Nasen kleiner gewählt ist als die Breite des zweiten Kontaktelementes im Bereich des korrespondierenden Halteabschnittes.In a further preferred embodiment of the invention, the two fixing arms on a straight linear section. It is also advantageous if the fixing arms following the said linear sections a nose have or form by a curvature portion which extends in the direction of the respective opposite fixing arm and wherein the distance of the two lugs is chosen smaller than the width of the second contact element in the region of the corresponding holding portion.

In einer besonders vorteilhaften Ausgestaltung entspricht die Länge des jeweiligen Linearabschnittes der Höhe des zweiten Kontaktelementes im Bereich des korrespondierenden Halteabschnittes entspricht der Abstand der beiden Innenseiten der Linearabschnitte in etwa der Breite des zweiten Kontaktelementes im Bereich des korrespondierenden Halteabschnittes. Durch eine solche Ausgestaltung wird sichergestellt, dass beim Aufstecken des ersten Kontaktelementes auf den Halteabschnitt des zweiten Kontaktelementes die Arme-des Fixierelementes auseinanderfedern und über den Halteabschnitt einschnappen bzw. wieder in ihre ursprüngliche Lage zurückfedern und der Halteabschnitt dann sowohl seitlich (durch die Linearabschnitte), in Richtung der Öffnung des Fi'xiermittels (durch die Nasen) und nach "Oben" durch den Mittelsteg des U-förmigen Fixierelementes in einer definierten Position fixiert jedoch lösbar gehalten wird.In a particularly advantageous embodiment, the length of the respective linear section corresponds to the height of the second contact element in the region of the corresponding holding section corresponds to the distance between the two inner sides of the linear sections approximately the width of the second contact element in the region of the corresponding holding section. Such an embodiment ensures that when attaching the first contact element to the holding section of the second contact element, the arms of the fixing element spring apart and snap over the holding section or spring back into their original position and the holding section then both laterally (by the linear sections), in the direction of the opening of the Fi'xiermittels (through the lugs) and after "above" by the central web of the U-shaped fixing element fixed in a defined position, however, is releasably held.

Die beiden Schweißverbindungsabschnitte 11, 21 sind so ausgebildet, um miteinander in Anlage gebracht zu werden und um die Kontaktelemente 10, 20 materialschlüssige miteinander verbinden zu können, wie dies in Figur 3 für ein Set von Kontaktsystemen 1 dargestellt ist.The FIG. 1 shows a perspective view of a first embodiment of a first contact element 10 of an inventive electrical contact system 1 and in FIG. 2 is a perspective view of the first contact element 10 of the FIG. 1 together with a stamped grid element 20 (contact element 20) for producing a contact system 1 according to the invention. The electrical contact system 1 accordingly consists of the first contact element 10, which is formed with a welded connection section 11, and the second contact element 20, which is likewise formed with a welded connection section 21. The two weld connection sections 11, 21 are designed to be brought into contact with each other and to be able to connect the contact elements 10, 20 to one another in a material-locking manner, as shown in FIG FIG. 3 for a set of contact systems 1 is shown.

Das erste Kontaktelement 10 hat einen zentralen Flachabschnitt, der den Schweißverbindungsabschnitt 11 ausbildet. Benachbart zum Schweißverbindungsabschnitt 11 ist ein U-förmig gebogenes federndes Fixierelement 12 ausgebildet. Das Fixierelement 12 ist in seiner Abmessung und Form so gestaltet, dass es bestimmungsgemäß zum klemmenden Halten und Fixieren des Halteabschnittes 22 des zweiten Kontaktelementes 20 dient. Daher bildet das Fixierelement 12 zwei Fixierarme 12a, 12b aus, die sich (in der Fig. 2) "senkrecht nach unten" in Richtung zum fixierenden Kontaktelement 20 erstrecken.The first contact member 10 has a central flat portion forming the weld joint portion 11. Adjacent to the welded connection section 11, a U-shaped resilient fixing element 12 is formed. The fixing element 12 is designed in its dimension and shape so that it serves as intended for clamping holding and fixing of the holding portion 22 of the second contact element 20. Therefore, the fixing element 12 forms two fixing arms 12a, 12b, which (in the Fig. 2 ) extend "vertically downwards" in the direction of the fixing contact element 20.

Das zweite Kontaktelement 20 bildet einen korrespondierenden Halteabschnitt 22 benachbart zum Schweißverbindungsabschnitt 21 so aus, dass sich, im für den Schweißprozess vorfixierten Zustand, die beiden Schweißverbindungsabschnitte 11, 21 berührend gegenüberliegen. Auf der Oberseite 21a des Schweißverbindungsabschnittes 22 des Kontaktelement 20 ist eine Schweißkuppe 23 bzw. Schweißlinse vorgesehen.The second contact element 20 forms a corresponding holding section 22 adjacent to the welded connection section 21 such that, in the state pre-fixed for the welding process, the two welded connection sections 11, 21 are in contact with each other. On the upper side 21a of the welded connection section 22 of the contact element 20, a welding tip 23 or weld nugget is provided.

In der Figur 3, sind die jeweils beiden Kontaktelemente 10, 20 materialschlüssig im Bereich der Schweißverbindungsabschnitte 11, 21 miteinander verbunden. An dem Schweißverbindungsabschnitt 11 des ersten Kontaktelementes 10 sind ferner Crimpanschlußzungen 11a, 11b zum Anschluß einer Leitung 30 einstückig mit dem Kontaktelement 10 ausgebildet.In the FIG. 3 , The respective two contact elements 10, 20 are materially connected to one another in the region of the welded connection sections 11, 21. Further, at the weld connecting portion 11 of the first contact member 10, crimping terminal tongues 11a, 11b are integrally formed with the contact member 10 for connecting a lead 30.

Es ist ferner aus den Figuren ersichtlich, dass der Schweißverbindungsabschnitt 11 des Kontaktelements 10 eine Oberseite 11a und eine der Oberseite gegenüberliegende, als Schweißverbindungsseite 11 b ausgebildete Unterseite aufweist. Weiter zu erkennen ist, dass der Schweißverbindungsabschnitt 21 des Kontaktelements 20 eine Unterseite 21b und eine der Unterseite gegenüberliegende, als Schweißverbindungsseite 21 a ausgebildete Oberseite aufweist.It can also be seen from the figures that the welded connection section 11 of the contact element 10 has an upper side 11a and an upper side opposite the upper side, designed as a welded connection side 11b. It can also be seen that the weld connection section 21 of the contact element 20 has a lower side 21b and an upper side opposite the underside, designed as a welded connection side 21a.

Die beiden Fixierarme 12a, 12b erstrecken sich aus der von dem Schweißverbindungsabschnitt 11 gebildeten Unterseite 11b weg und zwar im Wesentlichen parallel zueinander in einem Winkel von 90° lotrecht von der Fläche weg und sind an ihrem oberen Teil mit einem quer verlaufenden Basisteil verbunden. Die beiden Fixierarme 12a, 12b weisen ferner einen gerade verlaufenden Linearabschnitt 12c auf und es ist ferner im Anschluss an den Linearabschnitt 12c eine Nase 12d ausgebildet, die sich in Richtung des jeweils gegenüberliegenden Fixierarms erstreckt. Der Abstand der beiden Nasen 12d ist kleiner gewählt als die Breite des zweiten Kontaktelementes 20 im Bereich des korrespondierenden Halteabschnittes 22. Wie in Figur 3 ersichtlich, ist die Außengeometrie der beiden Flachkontaktabschnittsbereiche in etwa identisch, so dass diese übereinander fluchtend angeordnet werden können.The two fixing arms 12a, 12b extend away from the underside 11b formed by the welded connection portion 11 substantially perpendicular to each other at an angle of 90 ° away from the surface and are connected at their upper part to a transverse base part. The two fixing arms 12a, 12b furthermore have a straight linear section 12c and, in addition to the linear section 12c, a lug 12d is also formed, which extends in the direction of the respectively opposite fixing arm. The spacing of the two lugs 12d is selected smaller than the width of the second contact element 20 in the region of the corresponding holding section 22. As in FIG FIG. 3 can be seen, the outer geometry of the two flat contact portion regions are approximately identical, so that they can be arranged one above the other in alignment.

Die Länge des Linearabschnitt 12c entspricht vorliegend etwa der Höhe des zweiten Kontaktelementes 20 im Bereich des korrespondierenden Halteabschnittes 22. Ferner entspricht der Abstand der beiden Innenseiten der Linearabschnitte 12c in etwa der Breite des zweiten Kontaktelementes 20 im Bereich des korrespondierenden Halteabschnittes 22 entspricht. Die Schweißverbindungsabschnitte weißen eine im Wesentlichen quader-förmige Form mit rechteckigem Querschnitt auf.The length of the linear section 12c in the present case corresponds approximately to the height of the second contact element 20 in the region of the corresponding holding section 22. Furthermore, the distance of the two inner sides of the linear sections 12c corresponds approximately to the width of the second contact element 20 in the region of the corresponding holding section 22. The welded connection portions have a substantially rectangular parallelepiped shape with a rectangular cross section.
