Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines elektrischen Kontaktträgers gemäß dem Patentanspruch 1.The invention relates to a method for producing an electrical contact carrier according to claim 1.
In elektrischen Schaltgeräten sind elektrische Kontakte vorgesehen um einen Strompfad durch das Schaltgerät zu schließen bzw. geschlossen zu halten, oder zu öffnen bzw. geöffnet zu halten. Die betreffenden Kontakte sind dabei auf beweglichen oder unbeweglichen bzw. gehäusefesten Kontaktträgern angeordnet. Diese separate Ausbildung des Kontakts auf einem Kontaktträger hat sich aufgrund der hohen Anforderungen an die Kontakte durchgesetzt. Bei Schaltvorgängen kommt es zu kurzzeitigen Lichtbogenereignissen, und damit verbunden zu einem Materialabtrag, sowie zu einer hohen thermischen Belastung des Werkstoffes. Zudem sind die Kontakte den Umwelteinflüssen ausgesetzt, und sollen über lange Zeit hinweg gute elektrische Eigenschaften aufweisen, welche jedoch durch Oxidschichten beeinträchtigt werden können. Die Kontakte werden daher aus speziellen Werkstoffen gefertigt, um den entsprechend hohen Anforderungen zu genügen. Gängige Kontaktwerkstoffe für elektrische Kontrakte enthalten Edelmetalle wie etwa Silber oder Gold. Diese Werkstoffe sind selten und kostenintensiv.In electrical switchgear electrical contacts are provided to close a current path through the switching device or keep closed, or to open or keep open. The relevant contacts are arranged on movable or immovable or housing-fixed contact carriers. This separate training of the contact on a contact carrier has prevailed due to the high demands on the contacts. During switching operations, short-term arcing events occur, which in turn leads to material removal and high thermal stress on the material. In addition, the contacts are exposed to environmental influences, and should have over a long time good electrical properties, which, however, can be affected by oxide layers. The contacts are therefore made of special materials to meet the correspondingly high requirements. Common contact materials for electrical contracts contain precious metals such as silver or gold. These materials are rare and costly.
Es ist bekannt Kontaktträger herzustellen, wobei der Kontaktträger aus Kupfer bzw. eines Kupferlegierung gebildet ist, auf welchem ein elektrischer Kontakt aus einer Silber- und/oder Goldlegierung angeordnet ist. Dabei ist gemäß einem gängigen Verfahren vorgesehen, die Kontaktträger aus einem aufwendigen Halbzeug in Form eines Bimetalls bestehend aus einer Kupferlegierung für den Kontaktträger sowie einer Edelmetalllegierung als Kontaktmaterial für den eigentlichen Kontakt zu fertigen. Herstellungsbedingt wird dabei der Großteil der Edelmetalllegierung von dem Halbzeug abgetragen. Dabei ist etwa vorgesehen, dass der Großteil der Edelmetalllegierung abgesehen von dem Bereich, welcher den Kontakt selbst bilden soll, durch einen Stanzvorgang abgetragen wird. Durch diesen fertigungstechnisch rationellen Schritt wird der Bereich des zu bildenden Kontakts jedoch derart in Mitleidenschaft gezogen, dass es trotz eines nachfolgenden Prägeschrittes an den Ränder der Kontakte zu Qualitätsproblemen kommen kann, welche eine entsprechende Qualitätssicherung in diesem Bereich erforderlich machen, und einen hohen Ausschuss verursachen.It is known to produce contact carriers, wherein the contact carrier is formed of copper or a copper alloy, on which an electrical contact of a silver and / or gold alloy is arranged. It is provided according to a common method, the contact carrier from a complex semi-finished in shape a bimetal consisting of a copper alloy for the contact carrier and a noble metal alloy as a contact material for the actual contact to manufacture. Due to the manufacturing process, the majority of the noble metal alloy is removed from the semifinished product. It is intended, for example, that the majority of the noble metal alloy, apart from the region which is to form the contact itself, is removed by a punching process. By means of this production-efficient, rational step, however, the area of the contact to be formed is affected in such a way that, despite a subsequent embossing step at the edges of the contacts, quality problems may arise which require corresponding quality assurance in this area and cause a high rejection.

Erfindungsgemäß wird dies durch die Merkmale des Patentanspruches 1 erreicht.This is achieved by the features of claim 1 according to the invention.
Dadurch kann ein Kontaktträger mit einem elektrischen Kontakt gebildet werden, wobei nur geringer Abfall an Kontaktmaterial anfällt. Durch den rationellen Einsatz des in der Regel wenigstens ein Edelmetall umfassenden Kontaktmaterials können die Kosten für einen fertigen Kontaktträger deutlich reduziert werden. Weiters können dadurch wertvolle und seltene Ressourcen eingespart werden. Durch den Verzicht auf ein Stanzen des Kontaktmaterials im Bereich des zu bildenden Kontakts kann weiters die Fertigungsqualität in diesem Bereich deutlich erhöht werden, wodurch der Ausschuss verringert und die angewandten Qualitätssicherungsmaßnahmen reduziert werden können. Dadurch kann der Herstellungsaufwand reduziert und die Qualität erhöht werden.As a result, a contact carrier can be formed with an electrical contact, wherein only a small amount of contact material is obtained. Due to the rational use of the generally at least one noble metal comprehensive contact material, the cost of a finished contact carrier can be significantly reduced. Furthermore, valuable and rare resources can be saved. By dispensing with a punching of the contact material in the region of the contact to be formed, the production quality in this area can be further increased significantly, whereby the scrap can be reduced and the quality assurance measures applied can be reduced. As a result, the production cost can be reduced and the quality can be increased.

Dadurch kann der Herstellungsaufwand reduziert und die Qualität erhöht werden.As a result, a contact carrier 1 can be formed with an electrical contact 7, wherein only small waste of contact material 5 is obtained. As a result of the rational use of the contact material 5, which generally comprises at least one precious metal, the costs for a finished contact carrier 1 can be significantly reduced. Furthermore, valuable and rare resources can be saved. By dispensing with punching of the contact material 5 in the region of the contact 7 to be formed, the production quality in this area can be further increased significantly, as a result of which the scrap can be reduced and the quality assurance measures used can be reduced. As a result, the production cost can be reduced and the quality can be increased.

Es kann vorgesehen sein, das Grundprofil 3 auf unterschiedliche Art aus dem Grundmaterial 4 herauszuarbeiten, etwa durch spanabhebende Formgebungsverfahren wie etwa Fräsen oder Feilen. Bevorzugt ist vorgesehen, dass das Grundprofil 3 zufolge nichtspanabhebender Verfahren, insbesondere durch Stanzen und/oder Prägen, in dem Grundmaterial 4 hergestellt wird. Derartige Verfahren weisen besondere Vorteile in der Großserienproduktion auf. Die Figur zeigt das Grundmaterial 4 mit bereits hergestellten Grundprofilen 3.It is envisaged that a base profile 3 is produced in the base material 4. The base profile 3 forms the contour of the contact carrier 1 on at least one side, in particular the side on which the contact 7 is formed. It can be provided to work out the base profile 3 in different ways from the base material 4, for example by means of cutting shaping methods such as milling or filing. It is preferably provided that the base profile 3 according to nichtspanabhebender method, in particular by punching and / or embossing, is produced in the base material 4. Such methods have particular advantages in mass production. The figure shows the base material 4 with basic profiles 3 already produced.
Nach Herstellung des Grundprofils 3 ist vorgesehen, dass ein Kontaktmaterial 5 auf einen Kontaktaufnahmebereich 6 aufgebracht wird.After production of the base profile 3, it is provided that a contact material 5 is applied to a contact receiving area 6.
Der Kontaktaufhahmebereich 6 bezeichnet dabei den Bereich, an welchem der elektrische Kontakt 7 angeordnet werden soll. Dabei kann vorgesehen sein, dass der Kontaktaufnahmebereich 6 bereits bei Herstellung des Grundprofils 3 gebildet wird. Bevorzugt ist vorgesehen, dass der Kontaktaufnahmebereich 6 nach Herstellung des Grundprofils 3 durch prägen und/oder stauchen am Grundprofil 3 ausgebildet wird. Dadurch kann der Kontaktaufhahmebereich 6 hinsichtlich Größe und/oder Oberflächenbeschaffenheit gut und einfach an die weiteren Anforderungen angepasst werden. Die einzige Figur zeigt an der linken Seite ein bereits hergestelltes Grundprofil 3 mit einem Prägestempel 8 vor Herstellung des Kontaktaufnahmebereichs 6.In this case, the contact receiving area 6 designates the area at which the electrical contact 7 is to be arranged. It can be provided that the contact receiving area 6 is already formed during production of the base profile 3. It is preferably provided that the contact receiving area 6 after embossing and / or compressing the base profile 3 is formed on the base profile 3.

The sole FIGURE shows on the left side an already produced basic profile 3 with an
Wie bereits dargelegt, ist in weiterer Folge vorgesehen, auf den Kontaktaufnahmebereich 6 ein Kontaktmaterial 5 aufzubringen. Dadurch, dass das Kontaktmaterial 5 lediglich auf den Kontaktaufnahmebereich 6 aufgebracht wird, kann ein übermäßiger Materialeinsatz in diesem Bereich vermieden werden. Dabei können unterschiedliche Verfahren vorgesehen sein, um das Kontaktmaterial 5 auf dem Kontaktaufnahmebereich 6 aufzubringen und dauerhaft mit diesem zu verbinden, etwa Schweißen, Löten oder Nieten.As already stated, it is subsequently provided to apply a contact material 5 to the contact receiving region 6. The fact that the contact material 5 is applied only to the contact receiving area 6, an excessive use of material in this area can be avoided. In this case, different methods can be provided to Apply the contact material 5 on the contact receiving portion 6 and permanently connect to this, such as welding, soldering or riveting.
Bevorzugt ist dabei vorgesehen, dass das Kontaktmaterial 5 auf den Kontaktaufnahmebereich 6 geschweißt bzw. aufgeschweißt wird, wodurch fertigungstechnisch einfach automatisierbar eine sichere und dauerhafte Verbindung zwischen dem Kontaktmaterial 5 und dem Kontaktaufnahmebereich 6 geschaffen werden kann. Es können dabei unterschiedliche Schweißverfahren vorgesehen sein.Preferably, it is provided that the contact material 5 is welded or welded onto the contact receiving area 6, whereby a safe and permanent connection between the contact material 5 and the contact receiving area 6 can be created easily automated manufacturing technology. There may be provided different welding methods.
Je nach Art der Verbindung des Kontaktmaterials 5 mit dem Kontaktaufnahmebereich 6, kann eine unterschiedliche Art der Bereitstellung des Kontaktmaterials 5 besonders vorteilhaft sein. Bevorzugt ist vorgesehen, dass das Kontaktmaterial 5 als drahtförmiges Kontaktmaterial 5 auf den Kontaktaufhahmebereich 6 aufgebracht wird. Dadurch ergibt sich die besonders vorteilhafte Möglichkeit - bei verschweißen des Kontaktmaterials 5 mit dem Kontaktaufnahmebereich 6 - das drahtförmige Kontaktmaterial 5 als Schweißdraht zu verwenden, und ohne Änderungen an vorhandenen Schweißrobotern auszukommen.Depending on the type of connection of the contact material 5 with the contact receiving area 6, a different way of providing the contact material 5 may be particularly advantageous. It is preferably provided that the contact material 5 is applied as a wire-shaped contact material 5 on the Kontaktaufhahmebereich 6. This results in the particularly advantageous possibility - when welding the contact material 5 with the contact receiving area 6 - to use the wire-shaped contact material 5 as a welding wire, and to make do without changes to existing welding robots.
Der Begriff "drahtförmig" bezeichnet dabei einen Metallstrang, dessen mittlere Querschnittsabmessung wenigstens bei bzw. nach dessen Herstellung deutlich kleiner ist als dessen Längserstreckung. Das drahtförmige Kontaktmaterial 5 kann jeden Querschnitt aufweisen, wobei bevorzugt vorgesehen ist, dass das drahtförmige Kontaktmaterial 5 einen kreisrunden, elliptischen oder rechteckigen Querschnitt aufweist. Es können aber auch komplexere geometrische Querschnittsformen vorgesehen sein. Besonders bevorzugt ist vorgesehen, dass der Querschnitt des drahtförmigen Kontaktmaterials 5 derart gewählt wird, dass die nachfolgende Formung des Kontaktes unterstützt wird, indem durch die Formgebung des Querschnitts an Bereichen, an denen mehr Kontaktmaterial benötigt wird, auch entsprechend mehr Kontaktmaterial angeordnet wird, und vice versa. Dies kann etwa durch, beispielsweise zackenförmige, zahnradartige oder sinusförmige, Ausnehmungen am Rand des Querschnitts des drahtförmigen Kontaktmaterials 5 erreicht werden. Beispielsweise kann ein Querschnittsprofil entsprechend einem Torx-Schraubendreher vorgesehen sein.The term "wire-shaped" refers to a metal strand whose average cross-sectional dimension, at least during or after its production, is significantly smaller than its longitudinal extension. The wire-shaped contact material 5 may have any cross-section, wherein it is preferably provided that the wire-shaped contact material 5 has a circular, elliptical or rectangular cross-section. But it can also be provided more complex geometric cross-sectional shapes. It is particularly preferably provided that the cross-section of the wire-shaped contact material 5 is selected such that the subsequent shaping of the contact is assisted by arranging correspondingly more contact material by forming the cross-section at regions where more contact material is required, and vice versa versa. This can be achieved, for example, by teeth, gear-like or sinusoidal, recesses at the edge of the cross-section of the wire-shaped contact material 5. For example, a cross-sectional profile may be provided corresponding to a Torx screwdriver.
Die einzige Figur zeigt symbolisch einen Teil des drahtförmigen Kontaktmaterials 5 oberhalb eines bereits angeschweißten, aber noch nicht abschließend fertiggestellten Kontakts 7.The single figure symbolically shows a part of the wire-shaped contact material 5 above an already welded, but not yet finished finished contact. 7
Insbesondere bei Aufbringen des Kontaktmaterials 5 als drahtförmiges Kontaktmaterial 5 kann möglicherweise geringfügig mehr Kontaktmaterial 5 auf dem Kontaktaufhahmebereich 6 aufgebracht worden sein, als erforderlich. Da sich dies in weiterer Folge negativ auswirken kann, ist gemäß eines bevorzugten Ausführung des gegenständlichen Verfahrens vorgesehen, dass nach dem Aufbringen des Kontaktmaterials 5 auf den Kontaktaufnahmebereich 6 überschüssiges Kontaktmaterial 5 abgetrennt wird. Die einzige Figur zeigt stilisiert die Messer einer Abtrennvorrichtung 10. Bei dem dabei abgetrennten Kontaktmaterial 5 handelt es sich noch immer um das reine Kontaktmaterial 5, was ein recyceln des Kontaktmaterials 5 einfach ermöglicht.In particular, when applying the contact material 5 as a wire-shaped contact material 5 may slightly more contact material 5 on the Kontaktaufhahmebereich. 6 have been applied as required. Since this can subsequently have a negative effect, it is provided according to a preferred embodiment of the subject method that after application of the contact material 5 on the contact receiving area 6 excess contact material 5 is separated. The single figure stylized shows the blades of a separating
Nach Aufbringen des Kontaktmaterials 5, und gegebenenfalls einem Abtrennen überschüssigen Kontaktmaterials 5, ist vorgesehen, dass das Kontaktmaterial 5 zu einem Kontakt 7 geformt wird. Dabei wird das aufgebrachte Kontaktmaterial 5 in dessen Form verändert, um den besonderen Anforderungen der Formgebung elektrischer Kontakte 5 zu entsprechen. Hiezu können unterschiedliche mechanische Verfahren vorgesehen sein, etwa schleifen oder ätzen. Gemäß einer bevorzugten Ausbildung des gegenständlichen Verfahrens ist vorgesehen, dass das aufgebrachte Kontaktmaterial 5 durch Prägen zu einem Kontakt 7 geformt wird. Dies stellt ein besonders gut automatisierbares Verfahren dar, mit welchem andauernd gleichbleibende Qualität erzielt werden kann. Die Figur zeigt diesbezüglich einen entsprechenden Kontaktprägestempel 11. Aufgrund des aufgebrachten Kontaktmaterials kann dieser Prägevorgang deutlich besser und mit erheblich geringerem Ausschuss erfolgen, als beim eingangs beschriebenen bekannten Verfahren.After application of the contact material 5, and possibly a separation of excess contact material 5, it is provided that the contact material 5 is formed into a contact 7.
