Description

Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen eines Kontaktsteckers sowie einen Kontaktstecker. Kontaktstecker werden üblicherweise durch Zerspanen von bleihaltigen Kupfer- und Messinglegierungen hergestellt. Die Zerspanbarkeit von Rohlingen wird dabei durch Zulegierung von Blei verbessert. Aufgrund der nachweislich gesundheitsschädlichen Wirkung von Blei, wird die Verwendung von Blei zunehmend normativ eingeschränkt.The present invention relates to a method for producing a contact plug and a contact plug. Contact plugs are usually manufactured by machining lead-containing copper and brass alloys. The machinability of blanks is improved by adding lead. Due to the proven harmful effects of lead on health, the use of lead is increasingly being restricted by standards.

Grundsätzlich besteht bei der Herstellung von Kontaktsteckern, die einen Crimpanschluss aufweisen, die Herausforderung, einen Werkstoff bereitzustellen, der einerseits gut zerspanbar ist, und andererseits eine ausreichend hohe Kaltverformbarkeit hat, um in zuverlässiger Weise haltbare, rissfreie Crimpverbindungen herzustellen. Dieser Kompromiss wird heute durch bleihaltige Kupfer- oder Messinglegierungen erreicht, die einerseits gut zerspanbar und zudem ohne Rissbildung crimpbar ist.In principle, when manufacturing contact plugs that have a crimp connection, the challenge is to provide a material that is easy to machine on the one hand and has sufficiently high cold deformability on the other hand to reliably produce durable, crack-free crimp connections. Today, this compromise is achieved with lead-containing copper or brass alloys, which on the one hand are easy to machine and can also be crimped without cracking.

Für bleifreie Messinglegierungen lässt sich ein solcher Kompromiss zwischen einer guten Zerspanbarkeit, also sprödhartem Verhalten, und Crimpbarkeit, was eine hohe Duktilität erfordert, nicht in praxistaugliche Weise erreichen. So neigen Crimpverbindungen aus Messinglegierungen zu Rissbildung.Such a compromise between good machinability, i.e. brittle behavior, and crimpability, which requires high ductility, cannot be achieved in a practical way for lead-free brass alloys. Brass alloy crimp connections tend to crack.

Weiter erfordert die Zerspanung bleifreier Messinglegierungen hohe Zerspankräfte, die üblicherweise nur mit gekühlten Bohrer an prozesssicher erreicht werden können, was zu erhöhten Fertigungskosten führt. Bei der zerspanenden Fertigung besteht zudem grundsätzlich der Nachteil, dass ein Materialverlust von bis zu 50 % in Kauf genommen wird.Furthermore, the machining of lead-free brass alloys requires high machining forces, which can usually only be reliably achieved with cooled drills, which leads to increased production costs. In the case of machining, there is also the fundamental disadvantage that a material loss of up to 50% has to be accepted.

EP 2 937 943 A1 und JP 2012 221774 A offenbaren jeweils die Herstellung eines Kontaktsteckers mit einem einem Crimpbereich und einem Steckbereich mit Lamellen durch Kaltumformung eines Rohlings aus reinem Kupfer. EP 2 937 943 A1 and JP 2012 221774 A each disclose the manufacture of a contact plug having a crimping area and a mating area with laminations by cold forming a blank of pure copper.

DE 20 2008 014774 U1 offenbart die Herstellung eines Steckerstiftes für einen Netzstecker aus einer bleifreien Messinglegierung mit einem Steckbereich, der durch Kaltumformung hergestellt wird, und einem Crimpbereich, der durch Warmumformung hergestellt wird. DE 20 2008 014774 U1 discloses the manufacture of a male connector pin for a power plug from a lead-free brass alloy having a mating portion formed by cold stamping and a crimping portion formed by hot stamping.

Vor diesem Hintergrund liegt der Erfindung die technische Problemstellung zugrunde, ein Verfahren zum Herstellen eines Kontaktsteckers sowie einen Kontaktstecker anzugeben, welche die voranstehend beschriebenen Nachteile nicht oder zumindest in geringerem Maße aufweisen, und insbesondere einen bleifreien Kontaktstecker ermöglichen, der in einem Crimpbereich eine ausreichend hohe und insbesondere rissfreie Verformbarkeit bereitstellt.Against this background, the invention is based on the technical problem of specifying a method for producing a contact plug and a contact plug which do not have the disadvantages described above, or at least do so to a lesser extent, and in particular enable a lead-free contact plug which has a sufficiently high and in particular provides crack-free deformability.

Die voranstehend beschriebene, technische Problemstellung wird jeweils gelöst durch ein Verfahren nach Anspruch 1 und einen Kontaktstecker nach Anspruch 9. Weitere Ausgestaltungen des Verfahrens ergeben sich aus den abhängigen Ansprüchen und der nachstehenden Beschreibung.The technical problem described above is solved in each case by a method according to claim 1 and a contact plug according to claim 9. Further refinements of the method result from the dependent claims and the description below.

Gemäß einem ersten Aspekt betrifft die Erfindung ein Verfahren zum Herstellen eines Kontaktsteckers, mit den Verfahrensschritten: Bereitstellen eines Rohlings, der aus einer bleifreien Messinglegierung besteht; Halbwarmumformung eines ersten Abschnitts des Rohlings zu einem Crimpbereich, wobei der Crimpbereich eine Öffnung zum Einführen eines Leiterendes hat und wobei der erste Abschnitt des Rohlings vor und/oder während der Halbwarmumformung auf eine Halbwarmumformtemperatur erwärmt wird; Kaltumformung eines zweiten Abschnitts des Rohlings zu einem Steckbereich, wobei der Steckbereich eine Mehrzahl von Lamellen hat.According to a first aspect, the invention relates to a method for producing a contact plug, with the method steps: providing a blank which consists of a lead-free brass alloy; warm forming a first portion of the blank into a crimping area, the crimping area having an opening for insertion of a conductor end and wherein the first portion of the blank is heated to a warm forming temperature before and/or during the warm forming; Cold forming a second portion of the blank into a tab portion, the tab portion having a plurality of fins.

Durch die angegebene Temperaturführung der Crimpbereich mit einem Gefüge bereitgestellt werden, dass eine geringe Kaltverfestigung aufweist und somit eine hohe Duktilität für einen Crimpvorgang hat. So kann ein zuverlässiges Vercrimpen eines Leiterendes mit dem Crimpbereich erfolgen, ohne, dass es zu Rissbildung im Bereich der Crimpverbindung kommt.The specified temperature control provides the crimping area with a structure that exhibits low strain hardening and thus has high ductility for a crimping process. A conductor end can thus be reliably crimped to the crimp area without cracks forming in the area of the crimp connection.

Die Kaltumformen des Steckbereichs führt zu einer Kaltverfestigung, so dass der Steckbereich beim Herstellen einer Steckverbindung nicht oder nur in geringem Maße plastisch verformt wird, und maßgeblich elastisch verformt wird, um entsprechende Federkräfte reversibel bereitzustellen.The cold forming of the plug-in area leads to strain hardening, so that the plug-in area is not plastically deformed or only to a small extent when a plug-in connection is made, and is significantly elastically deformed in order to provide corresponding spring forces reversibly.

Die voranstehende Auflistung der Verfahrensschritte gibt keine zwingende Reihenfolge der Verfahrensschritte vor. So können die Verfahrensschritte in der Reihenfolge der Auflistung durchgeführt werden, oder in einer davon abweichenden Reihenfolge. Beispielsweise kann vorgesehen sein, dass, abweichend von der Reihenfolge der Auflistung, eine Kaltumformung des zweiten Abschnitts vor der Halbwarmumformung des ersten Abschnitts erfolgt.The list of method steps above does not specify a mandatory order of the method steps. Thus, the method steps can be carried out in the order in which they are listed, or in a different order. For example, it can be provided that, in deviation from the order in which they are listed, cold forming of the second section takes place before warm forming of the first section.

Nach einer weiteren Ausgestaltung des Verfahrens ist vorgesehen, dass die Halbwarmumformtemperatur in einem Bereich von einschließlich 250°C bis einschließlich 450°C liegt. So kann die Halbwarmumformtemperatur beispielsweise 350°C betragen.According to a further embodiment of the method, it is provided that the semi-hot forming temperature is in a range from 250° C. up to and including 450° C. For example, the semi-hot forming temperature can be 350°C.

Wenn vorliegend von einer Kaltumformung gesprochen wird, so handelt es sich dabei um eine Umformung bei einer Temperatur unterhalb der Halbwarmumformtemperatur.When cold forming is mentioned here, it is a forming at a temperature below the semi-hot forming temperature.

Die Kaltumformung kann bei einer Temperatur von weniger als 100°C stattfinden, insbesondere bei einer Temperatur von weniger als 50°C stattfinden, weiter insbesondere bei Raumtemperatur in einem Bereich von 15°C bis 30°C stattfinden.The cold forming can take place at a temperature of less than 100°C, in particular at a temperature of less than 50°C, further in particular at room temperature in a range from 15°C to 30°C.

Es versteht sich, dass die genannten Temperaturen die Materialtemperatur des umzuformenden Bauteils beziffern. Die Umgebungstemperatur kann davon abweichen und z.B. 25°C betragen.It goes without saying that the stated temperatures number the material temperature of the component to be formed. The ambient temperature can deviate from this and be 25°C, for example.

Es kann gemäß einer weiteren Ausgestaltung des Verfahrens vorgesehen sein, dass der zweite Abschnitt vor und/oder während der Kaltumformung des zweiten Abschnitts gekühlt wird. So kann vermieden werden, dass z.B. ein Temperatureintrag aus einem vorangegangenen Halbwarmumformen zu einem Erwärmen des zweiten Abschnitts oberhalb einer vorgesehenen Kaltumformtemperatur führt.According to a further embodiment of the method, it can be provided that the second section is cooled before and/or during the cold forming of the second section. In this way it can be avoided that, for example, a temperature input from a previous semi-hot forming leads to the second section being heated above an intended cold forming temperature.

Alternativ oder ergänzend kann vorgesehen sein, dass der erste Abschnitt vor und/oder während der Kaltumformung des zweiten Abschnitts gekühlt wird. So kann der erste Abschnitt beispielsweise aus einem vorangegangenen Halbwarmumformen erwärmt sein, wobei durch die Kühlung ein Wärmefluss hin zu dem zweiten Abschnitt vermieden bzw. reduziert wird.Alternatively or additionally, it can be provided that the first section is cooled before and/or during the cold forming of the second section. For example, the first section can be heated from a previous semi-hot forming, with the cooling avoiding or reducing a flow of heat to the second section.

Nach einer weiteren Ausgestaltung des Verfahrens kann vorgesehen sein, dass der zweite Abschnitt vor und/oder während und/oder nach dem Erwärmen des ersten Abschnitts gekühlt wird. Alternativ oder ergänzend kann vorgesehen sein, dass die Temperatur des zweiten Abschnitts vor und/oder während und/oder nach dem Umformen des ersten und zweiten Abschnitts jederzeit unterhalb von 100°C ist, insbesondere unterhalb von 50°C ist, insbesondere bei Raumtemperatur in einem Bereich von 15°C bis 30°C gehalten wird.According to a further embodiment of the method it can be provided that the second section is cooled before and/or during and/or after the heating of the first section. Alternatively or additionally, it can be provided that the temperature of the second section before and/or during and/or after the forming of the first and second section is always below 100° C., in particular below 50° C., in particular at room temperature in one range of 15°C to 30°C.

Der Begriff "jederzeit" bezieht sich hier auf die Zeitdauer des in Rede stehenden Herstellverfahrens.As used herein, the term "at any time" refers to the length of time of the manufacturing process in question.

Durch die Kühlung des ersten und/oder zweiten Abschnitts kann sichergestellt werden, dass sich in dem zweiten Abschnitt trotz des Erwärmens des ersten Abschnitts die gewünschte Kaltverfestigung einstellt.The cooling of the first and/or second section can ensure that the desired strain hardening occurs in the second section despite the heating of the first section.

Eine weitere Ausgestaltung des Verfahrens ist dadurch gekennzeichnet, dass ein Teilbereich des durch Halbwarmumformung gebildeten Crimpbereichs nach der Halbwarmumformung kaltumgeformt wird. So kann beispielsweise ein Endabschnitt des Crimpbereichs zu einem umlaufenden Kragen geformt werden, der infolge einer Kaltverfestigung lokal eine höhere Festigkeit aufweist, als der daran angrenzende Teil des Crimpbereichs.A further embodiment of the method is characterized in that a partial area of the crimping area formed by semi-hot forming is cold-formed after semi-hot forming. For example, an end section of the crimping area can be formed into a circumferential collar which, as a result of strain hardening, locally has greater strength than the part of the crimping area adjoining it.

Bei den Lamellen kann es sich um axial auskragende Federstege handeln. Alternativ oder ergänzend können die Lamellen in äquidistanten Winkelabständen um eine zentrale Öffnung angeordnet sein. Alternativ oder ergänzend können zwischen den Lamellen axiale Schlitze gebildet sind. Mithilfe der Lamellen kann eine zuverlässige Steckverbindung bereitstellt werden.The lamellae can be axially projecting spring bars. Alternatively or additionally, the slats can be arranged at equidistant angular intervals around a central opening. Alternatively or additionally, axial slots can be formed between the lamellae. A reliable plug connection can be provided with the aid of the lamellae.

Nach einer weiteren Ausgestaltung des Verfahrens erfolgt ein Kühlen mittels einer an einem Presswerkzeug gehaltenen oder in ein Presswerkzeug integrierten Kühleinrichtung. Alternativ oder ergänzend erfolgt ein Erwärmen mittels einer an einem Presswerkzeug gehaltenen oder in ein Presswerkzeug integrierten Heizeinrichtung, wie einer Induktionsheizeinrichtung, einer Widerstandsheizeinrichtung oder dergleichen. So können Kühl- und oder Heizeinrichtung kompakt in ein Presswerkzeug integriert und nach Bedarf zuschaltbar sein.According to a further embodiment of the method, cooling takes place by means of a cooling device which is held on a pressing tool or is integrated in a pressing tool. Alternatively or additionally, heating takes place by means of a heating device held on a pressing tool or integrated into a pressing tool, such as an induction heating device, a resistance heating device or the like. Cooling and/or heating devices can be integrated compactly into a pressing tool and can be switched on as required.

Es kann vorgesehen sein, dass das Umformen, also sowohl das Warmumformen als auch das Kaltumformen, mithilfe einer Mehrstufenpresse erfolgt, wobei die Mehrstufenpresse wenigstens eine Heizeinrichtung und wenigstens eine Kühleinrichtung aufweist. Wie voranstehend beschrieben, können eine Heiz- und Kühleinrichtung in Werkzeugen der Mehrstufenpresse integriert sein.Provision can be made for the forming, ie both the hot forming and the cold forming, to be carried out using a multi-stage press, the multi-stage press having at least one heating device and at least one cooling device. As described above, a heating and cooling device can be integrated in tools of the multi-stage press.

Gemäß einem zweiten Aspekt betrifft die Erfindung einen Kontaktstecker, der aus einer bleifreien Messinglegierung besteht, mit einem durch Halbwarmumformung eines ersten Abschnitts eines Rohlings umgeformten Crimpbereich, wobei der Crimpbereich eine Öffnung zum Einführen eines Leiterendes hat, und mit einem Steckbereich, wobei der Steckbereich eine Mehrzahl von Lamellen hat, wobei der Crimpbereich zumindest abschnittsweise eine geringere Kaltverfestigung aufweist, als der Steckbereich. So können einerseits eine gute Crimpbarkeit des Crimpbereichs als auch eine ausreichende Festigkeit und Steifigkeit der Lamellen erreicht werden. Es versteht sich, dass es sich hierbei um einen Vergleich der Kaltverfestigung des Crimpbereichs gegenüber der des Steckbereichs vor einem tatsächlichen Vercrimpen eines Leiterendes im Crimpbereich handelt.According to a second aspect, the invention relates to a contact plug, which consists of a lead-free brass alloy, with a crimping area formed by semi-hot forming of a first section of a blank, wherein the crimping area has an opening for inserting a conductor end, and with a plugging area, the plugging area having a plurality of lamellas, wherein the crimping area has, at least in sections, less strain hardening than the plugging area. In this way, on the one hand, good crimpability of the crimping area and sufficient strength and rigidity of the laminations can be achieved. It goes without saying that this is a comparison of the strain hardening of the crimping area compared to that of the plugging area before an actual crimping of a conductor end in the crimping area.

Es kann vorgesehen sein, dass der Kontaktstecker nach einem erfindungsgemäßen Verfahren hergestellt worden ist.Provision can be made for the contact plug to have been produced using a method according to the invention.

Es kann vorgesehen sein, dass der Kontaktstecker aus einer bleifreien Messinglegierung CuZn36, CuZn30, CuZn20, CuZn15 oder CuZn5 besteht.It can be provided that the contact plug consists of a lead-free brass alloy CuZn36, CuZn30, CuZn20, CuZn15 or CuZn5.

Mit Bezug zu den Figuren 1-5 wird nachfolgend zunächst ein erfindungsgemäßes Verfahren zum Herstellen eines Kontaktsteckers beschrieben. Ein mit dem erfindungsgemäßen Verfahren hergestellter Kontaktstecker 2 ist in Fig. 6 dargestellt.Related to the Figures 1-5 a method according to the invention for producing a contact plug is first described below. A contact plug 2 produced with the method according to the invention is in 6 shown.

Zum Herstellen des Kontaktsteckers 2 wird zunächst ein Rohling 4 bereitgestellt, der aus einer bleifreien Messinglegierung besteht.To produce the contact plug 2, a blank 4 is first provided, which consists of a lead-free brass alloy.

Nach dem Bereitstellen des Rohlings 4 wird ein erster Abschnitt 6 des Rohlings 4 durch Halbwarmumformung zu einem Crimpbereich 6 umgeformt. An dem Crimpbereich 6 wird mithilfe eines Werkzeugs 8 eine Öffnung 10 zum Einführen eines Leiterendes gebildet. Der erste Abschnitt 6 wird vorliegend vor und während der Halbwarmumformung mithilfe einer Induktionsheizeinrichtung 12 auf eine Halbwarmumformtemperatur von 350° erwärmt.After the blank 4 has been provided, a first section 6 of the blank 4 is formed into a crimping region 6 by warm forming. An opening 10 for inserting a conductor end is formed on the crimping area 6 with the aid of a tool 8 . In the present case, the first section 6 is heated to a warm forming temperature of 350° with the aid of an induction heating device 12 before and during the warm forming.

Während der Halbfahrerhalbwarmumformung des ersten Abschnitts 6 wird ein zweiten Abschnitt 14 des Rohlings 4 mithilfe einer Kühleinrichtung 16 aktiv gekühlt. Die Kühleinrichtung 16 weist Kühlkanäle 18 auf, die ein Kühlfluid führen.A second section 14 of the blank 4 is actively cooled with the aid of a cooling device 16 during semi-automatic semi-hot forming of the first section 6 . The cooling device 16 has cooling channels 18 which carry a cooling fluid.

Anschließend erfolgt ein in Fig. 3 dargestelltes Kaltumformen des zweiten Abschnitts 14, wobei während des Kaltumformens des zweiten Abschnitts 14 der erste Abschnitt 6 mithilfe einer Kühleinrichtung 20, die Kühlkanäle 22 zum Führen eines Kühlfluid aufweist, gekühlt wird.This is followed by an in 3 illustrated cold forming of the second portion 14, wherein during the cold forming of the second portion 14, the first portion 6 using a Cooling device 20, which has cooling channels 22 for guiding a cooling fluid, is cooled.

Wie den Figuren 2 und 3 zu entnehmen ist, sind die Heizvorrichtung 12 und die Kühlvorrichtungen 16, 22 integraler Bestandteil von Werkzeugen die den Rohling 4 während der Umformung einfassen.Like the Figures 2 and 3 can be seen, the heating device 12 and the cooling devices 16, 22 are an integral part of tools that enclose the blank 4 during the forming.

Fig. 4 zeigt eine weitere Kaltumformung des zweiten Abschnitts 14 zu einem Steckbereich 14, wobei mit einem Werkzeug 24 Lamellen 26 an dem zweiten Abschnitt 14 geformt werden. 4 14 shows a further cold forming of the second section 14 to form a plug-in area 14, lamellae 26 being formed on the second section 14 with a tool 24. FIG.

Bei den Lamellen 26 handelt es sich um axial auskragende Federstege, die um eine zentrale Öffnung in äquidistanten Winkelabständen angeordnet sind. Zwischen den Lamellen 26 sind vorliegend axiale Schlitze 38 gebildet.The lamellae 26 are axially projecting spring bars which are arranged at equidistant angular intervals around a central opening. In the present case, axial slots 38 are formed between the lamellae 26 .

In einem letzten Umformschritt wird gemäß Fig. 5 ein Teilbereich 28 des durch Halbwarmumformung gebildeten Crimpbereichs 6 kaltumgeformt. Der Bereich 28 bildet einen kreisrund umlaufenden Kragen 28.In a final forming step according to figure 5 a partial area 28 of the crimping area 6 formed by semi-hot forming is cold-formed. The area 28 forms a circular collar 28.

Durch das mit Bezug zu den Figuren 1-5 beschriebene, erfindungsgemäße Herstellverfahren, wird einem ersten Längenabschnitt 30 des Kontaktsteckers 2 ein kaltverfestigter Bereich bereitgestellt (vgl. Fig. 6), an den ein Längenabschnitt 32 mit einer geringeren Kaltverfestigung angeschlossen ist, der einen duktilen Crimpbereich bildet. Entlang des Längenabschnitts 34 entspricht die Festigkeit des Kontaktsteckers 2 im Wesentlichen der des ursprünglich bereitgestellten Rohlings 4. Entlang des Längenbereichs 36, in dem die Lamellen 26 durch Kaltumformen gebildet worden sind, ist die Kaltverfestigung am höchsten, da hier die höchsten Umformgrade bewirkt worden sind.Through that related to the Figures 1-5 described manufacturing method according to the invention, a first longitudinal section 30 of the contact plug 2 is provided with a work-hardened area (cf. 6 ) to which is attached a length portion 32 with less work hardening, forming a ductile crimp region. Along the longitudinal section 34, the strength of the contact plug 2 essentially corresponds to that of the originally provided blank 4. Along the longitudinal region 36, in which the lamellae 26 have been formed by cold forming, the strain hardening is highest, since the highest degrees of forming have been effected here.
