Description
Die vorliegende Erfindung betrifft eine mit einem Steckerteil durch eine Steckverbindung
koppelbare und elektrisch kontaktierbare Steckerbuchse nach dem Oberbegriff des
Anspruches 1 sowie ein Verfahren zur Herstellung einer derartigen Steckerbuchse.The present invention relates to a connector with a plug connection
couplable and electrically contactable plug socket according to the preamble of
Eine gattungsgemäße Steckerbuchse ist beispielsweise aus der US-A-5,033,982 bekannt, wobei diese Steckerbuchse einteilig ausgestaltet und aus einem Stanzteil hergestellt ist. Die Steckerbuchse weist Kontaktbereiche in Form von Lamellen auf, welche sich in Längsrichtung der Steckerbuchse parallel zur Längsachse erstrecken und derart gebogen sind, daß sich eine hyperbolische Form ergibt. Eine derartige Anordnung der Kontaktbereiche hat jedoch zur Folge, daß nicht immer ein zufriedenstellender elektrischer Kontakt zwischen dem entsprechenden Steckerteil und den Kontaktbereichen der Steckerbuchse gewährleistet ist.A generic connector is known for example from US-A-5,033,982, wherein this socket is designed in one piece and made from a stamped part. The Plug socket has contact areas in the form of lamellae, which are in The longitudinal direction of the socket extends parallel to the longitudinal axis and is bent in such a way that there is a hyperbolic form. Such an arrangement of the contact areas has however, with the consequence that not always a satisfactory electrical contact between the corresponding plug part and the contact areas of the plug socket is guaranteed.
Daher wurden abgewandelte Steckerbuchsen mit hyperbolisch ausgebildeten Kontaktbereichen entwickelt, die unter dem Namen HYPCON-Stecker bekannt sind. Eine entsprechende Steckerbuchse ist beispielhaft in Fig. 3 dargestellt. Therefore modified connectors with hyperbolic trained Contact areas developed, which are known under the name HYPCON connector. A corresponding plug socket is shown as an example in Fig. 3.
Wie aus Fig. 3 ersichtlich ist, weist diese bekannte Steckerbuchse einen im wesentlichen
zylinderförmigen Buchsenkörper 22 auf, der vergleichsweise dünnwandig und innen hohl
ist. Innerhalb des Buchsenkörpers 22 sind mehrere Kontaktdrähte 23 angeordnet, wobei
diese Kontaktdrähte 23 gegenüber der Längsachse der Steckerbuchse mit einem derartigen
Neigungswinkel angeordnet sind, daß sie im Inneren des Buchsenkörpers 22 einen die
Form eines Hyperboloids aufweisenden Körper begrenzen, so daß die Kontaktdrähte 23
hyperbolisch ausgebildete und angeordnete Kontaktbereiche für ein in die Steckerbuchse,
d.h. in das Innere des Buchsenkörpers 22, einzuführendes Steckerteil bilden. Das
Steckerteil besitzt insbesondere einen Kontaktstift, dessen Außenform komplementär zu
dem Buchsenkörper 22 ausgebildet ist. Als Außendurchmesser des Kontaktstifts und
entsprechend als Innendurchmesser des Buchsenkörpers 22 sind beispielsweise
Durchmesserwerte von 0,6 mm, 0,76 mm, 1,0 mm, 1,5 mm, 3,5mm, 7mm oder sogar
15mm usw. üblich.As can be seen from FIG. 3, this known plug socket essentially has one
Die in den Buchsenkörper 22 eingesetzten Kontaktdrähte 23 sind vorzugsweise aus Bronze
gefertigt. Die über die seitlichen Begrenzungen des Buchsenkörpers 22 hinausstehenden
Enden der Kontaktdrähte 23 werden wie in Fig. 3 gezeigt umgebogen, so daß sie die
Endbereiche des Buchsenkörpers 22 umgreifen, wodurch die Kontaktdrähte 23 innerhalb
des Buchsenkörpers 22 befestigt werden. The
Aufgrund der besonderen, in Fig. 3 dargestellten Gestaltung dieser sogen. HYPCON-Steckverbindungen
besitzen diese Steckverbindungen hervorragende elektrische und
mechanische Eigenschaften. So ist beispielsweise der zum Zusammenstecken bzw.
Auseinanderziehen der Teile erforderliche Kraftaufwand sehr gering. Die Abnutzung der
hyperbolisch innerhalb des Buchsenkörpers 22 angeordneten Kontaktdrähte 23 ist daher
sehr gering, wodurch die Lebensdauer enorm hoch ist. So sind beispielsweise bis zu
100 000 Steckverbindungsvorgänge mit ein und derselben Steckerbuchse möglich. Des
weiteren ist aufgrund der speziellen hyperbolischen Anordnung der Kontaktdrähte 23 der
Kontakt- und Übertragungswiderstand bei einer Steckverbindung minimal, so daß eine sehr
hohe Kontaktsicherheit gewährleistet ist. Schließlich ist die Steckverbindung auch
gegenüber Erschütterungen sicher, da die innerhalb des Buchsenkörpers 22 angeordneten
Kontaktdrähte 23 allseitig an einen eingeführten Kontaktstift anliegen.Due to the special design of this so-called. HYPCON plug connections
these connectors have excellent electrical and
mechanical properties. For example, the one for plugging together or
Pulling the parts apart requires very little effort. The wear of the
Aufgrund der oben beschriebenen hervorragenden Eigenschaften finden derartige
HYPCON-Steckverbindungen überall dort Anwendung, wo eine überaus hohe
Kontaktsicherheit gefordert ist, wie z.B. bei computergesteuerten Vorrichtungen.
Abhängig von der Anzahl der eingesetzten Kontaktdrähte 23 kann mit Hilfe einer
derartigen Steckverbindung bei einem Durchmesser 0.76mm Strom mit einer Stromstärke
von bis zu 6A übertragen werden. Abhängig von dem Durchmesser können jedoch
durchaus höhere Stromstärken bis zu 150A übertragen werden.Due to the excellent properties described above, such
HYPCON plug connections can be used wherever extremely high
Contact security is required, such as in computer-controlled devices.
Depending on the number of
Aufgrund des geringen Kraftaufwandes, der zum Zusammenstecken bzw. Auseinanderziehen der Teile erforderlich ist, kann eine Vielzahl von derartigen parallel angeordneten Steckverbindungen leicht zusammengesteckt und auseinandergezogen werden, was mit anderen Verbindungsarten nicht möglich wäre.Due to the low effort required to plug or Pulling apart the parts is required, a variety of such parallel arranged connectors easily plugged together and pulled apart what would not be possible with other connection types.
Wie aus Fig. 3 ersichtlich ist, ist die für eine derartige Steckverbindung erforderliche
Steckerbuchse relativ kompliziert aufgebaut und kann daher nur aufwendig hergestellt
werden. Insbesondere besteht diese Steckerbuchse aus einer Vielzahl von Einzelteilen, die
zunächst zusammengesetzt werden müssen. So müssen in einem ersten Schritt mehrere
Kontaktdrähte 23 in den Buchsenkörper 22 mit einem bestimmten Neigungswinkel
d.h. Schräg, gegenüber der Längsachse des Buchsenkörpers 22 eingesetzt werden, so daß diese
Kontaktdrähte 23 den hyperbolisch geformten Körper begrenzen. Anschließend müssen die
Seitenenden der Kontaktdrähte 23 wie in Fig. 3 gezeigt umgebogen werden, so daß die
Seitenenden die Endbereiche des Buchsenkörpers 22 umgreifen. Schließlich wird der
Buchsenkörper 22 mit den darin eingesetzten Kontaktdrähten 23 in zwei Hälften 20 und 21
eines Außengehäuses eingesetzt, wobei diese Außenhälften 20 und 21 beispielsweise
miteinander verbunden werden.As can be seen from Fig. 3, is required for such a connector
Plug socket is relatively complicated and can therefore only be manufactured with great effort
become. In particular, this connector consists of a variety of items
must first be put together. So in a first step,
Das Herstellungsverfahren der in Fig. 3 gezeigten bekannten Steckerbuchse ist somit sehr aufwendig, so daß eine vollautomatisierte Herstellung dieser Steckerbuchse nicht möglich ist. The manufacturing process of the known plug socket shown in FIG. 3 is thus very great complex, so that a fully automated production of this socket is not possible is.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Steckerbuchse, welche auf einfache Art und Weise und insbesondere billig, schnell und vollautomatisiert herstellbar ist und sehr gute Kontakteigenschaften aufweist, sowie ein Verfahren zur Herstellung einer derartigen Steckerbuchse bereitzustellen.The present invention is therefore based on the object of a plug socket can be produced in a simple manner and in particular cheaply, quickly and fully automatically is and has very good contact properties, and a method for producing a to provide such a socket.
Diese Aufgabe wird erfindungsgemäß durch eine Steckerbuchse mit den Merkmalen des
Anspruches 1 bzw. ein Verfahren zur Herstellung einer derartigen Steckerbuchse mit den
Merkmalen des Anspruches 16 gelöst. Die Unteransprüche definieren jeweils vorteilhafte und
bevorzugte Ausführungsformen der vorliegenden Erfindung. This object is achieved by a plug socket with the features of

Fig. 1 zeigt eine Draufsicht auf ein Stanzband 14, welches insbesondere aus einem
elektrisch leitfähigen Material, wie z.B. einem Bimetall, gefertigt ist. Aus dem Stanzband
14 wird ein Fertigungsteil 15 ausgestanzt, aus dem die in Fig. 2 gezeigte Steckerbuchse
hergestellt, d.h. insbesondere gebogen wird.Fig. 1 shows a plan view of a
Das Stanzteil 15 weist - als wesentlichen Bestandteil - einen Lamellenbereich 13 auf,
welcher in der späteren Steckerbuchse als aktiver Kontaktbereich dient. Der
Lamellenbereich 13 weist eine Vielzahl von im wesentlichen parallel und äquidistant
verlaufenden länglichen Lamellen 7 auf, die durch Ausstanzen entsprechender
Zwischenbereiche 16 zurückbleiben. Angrenzend zu diesen Lamellen 7 sind mehrere
Zungen 5 ausgestanzt, wobei bei dem in Fig. 1 und 2 dargestellten Ausführungsbeispiel
insbesondere vier Zungen vorhanden sind, deren Breite identisch ist und die äquidistant
angeordnet sind. Die Zungen 5 bilden einen Stabilisierungsbereich 12, der in der später
daraus hergestellten Steckerbuchse zur Stabilisierung des eigentlichen Kontaktabschnittes
dient.The stamped
Neben dem Stabilisierungsbereich 12 und dem Lamellenbereich 13 weist das Stanzteil
mehrere Laschen 8, 9 und 10 auf, wobei die Laschenpaare 8 und 9 als Kontaktbereich 11
für eine elektrische Kontaktierung eines an die Steckerbuchse anzuschließenden Leiters
dienen. Die Länge der Laschen 8 und 9 ist unterschiedlich, so daß mit den Laschenpaaren
8 und 9 unterschiedliche Leiterdurchmesser in Form einer Crimpverbindung kontaktierbar
sind. So kann beispielsweise mit den Laschen 8 ein Leiterdurchmesser von 1,5 bis 2,5
mm2 und mit den Laschen 9 ein Leiterdurchmesser zwischen 4,0 und 6,0 mm2 kontaktiert
werden. Das weitere Laschenpaar 10 ist zur Fixierung des an die Steckerbuchse
anzuschließenden elektrischen Leiters vorgesehen, wobei diese Laschen 10 ebenfalls im
Sinne einer Crimpung gebogen werden und auf diese Weise den Isolationsmantel der
elektrischen Leitung umgreifen und fixieren können. Die Laschen 10 dienen somit
zugleich als Zugentlastung. Vorteilhafterweise sind die Laschen 10 breiter ausgestaltet als
die Kontaktlaschen 8 und 9.In addition to the
Zwischen dem Lamellenbereich 13 und den Laschen 8 - 10 ist ein länglicher
Übergangsbereich 2 ausgebildet, der eine Führungsbohrung bzw. ein Führungsloch 4 für
eine automatische Crimpmaschine aufweist, so daß das Kontaktieren und Fixieren des oben
beschriebenen elektrischen Leiters, der mit der Steckerbuchse zu verbinden ist.
automatisch mit einer Crimpmaschine durchgeführt werden kann.Between the
Wie bereits beschrieben worden ist, ist das Stanzteil vorzugsweise aus einem Bimetall,
welches aus einem Basismaterial und einem sehr gut leitendem Material, welches den
Lamellen- oder Kontaktbereich 13 bildet, besteht. Dieses elektrisch gut leitende Material
kann auch auf bekannte Art und Weise auf das Basismaterial aufgebracht werden, wie z.B.
durch Aufwalzen oder galvanisches Auftragen. Vorteilhafterweise wird als Basismaterial
ein federndes bzw. federelastisches Material, wie z.B. Berylliumkupfer, gewählt. welches

Ausgangszustand zurückfedert. Als Material für den Lamellen- bzw. Kontaktbereich 13
kommt beispielsweise Silber oder insbesondere Gold in Betracht.As has already been described, the stamped part is preferably made of a bimetal,
which consists of a base material and a very good conductive material, which the

Der Lamellenbereich 13 wird zunächst verdreht und gestaucht, so daß sich der für diese
Art der Steckerbuchse typische hyperbolische Verlauf der Lamellen 7 ergibt, nachdem der
Lamellenbereich 13 in die in Fig. 2 gezeigte zylinderähnliche Form gebogen worden ist.
D.h., die nunmehr gegenüber der Längsachse der in Fig. 2 gezeigten Steckerbuchse schräg
verlaufenden Lamellen 7 bilden die Form eines Hyperboloids und entsprechen den in Fig.
3 verwendeten Kontaktdrähten 23, so daß die Lamellen 7 hyperbolisch angeordnete
Kontaktbereiche für einen Kontaktstift eines Steckers bilden.The
Die Zungen 5 werden derart nach außen geklappt bzw. gebogen, daß sie die Außenfläche
des Kontaktabschnitts 1 der Steckerbuchse bilden und insbesondere die Lamellen 7
stabilisieren. Der in Fig. 1 dargestellte Übergangsbereich 6 zwischen dem Lamellenbereich
13 und den Zungen 5 stellt bei der in Fig. 2 gezeigten Steckerbuchse, die aus dem in Fig.
1 gezeigten Stanzteil 15 hergestellt worden ist, eine obere Biegekante 6 dar.The
Die Laschenpaare 8 - 10 werden abschließend wie in Fig. 2 dargestellt gebogen, um (mit
Hilfe der Laschen 8 und 9) einen an die Steckerbuchse anschließbaren Leiter elektrisch zu
kontaktieren bzw. (mit Hilfe der Laschen 10) diesen Leiter zu fixieren. Die Laschen 8 und
9 bilden dabei mit dem Leiter eine Crimpverbindung. Auch die Laschen 10 werden in der
Form einer Crimpung gebogen, um den Isolationsmantel des elektrischen Leiters zu
umgreifen und zu fixieren. Die Laschen 8 - 10 bilden somit einen Befestigungsabschnitt 3,
während die Zungen 5 sowie die Lamellen 7 den bereits zuvor erwähnten Kontaktabschnitt
1 der in Fig. 2 gezeigten Steckerbuchse bilden.The pairs of tabs 8-10 are finally bent as shown in FIG. 2 in order to (with

Die obige Beschreibung macht deutlich, daß die erfindungsgemäße Steckerbuchse auf sehr einfache Art und Weise hergestellt werden kann, ohne daß die eingangs beschriebenen hervorragenden elektrischen und mechanischen Eigenschaften einer HYPCON-Steckverbindung verloren gehen. Insbesondere ist die erfindungsgemäße Steckerbuchse einteilig ausgestaltet, so daß die Materialkosten minimiert werden können. Des weiteren wird die erfindungsgemäße Steckerbuchse aus einem einzigen Stanzteil gebogen, welches zuvor aus einem elektrisch leitfähigen Material, beispielsweise einem Bimetall, ausgestanzt worden ist. Die Herstellung der erfindungsgemäßen Steckerbuchse ist somit gegenüber dem in Fig. 3 gezeigten Stand der Technik deutlich vereinfacht und billiger und kann insbesondere vollautomatisiert durchgeführt werden.The above description makes it clear that the plug socket according to the invention on very can be produced in a simple manner without the above-described excellent electrical and mechanical properties of a HYPCON connector get lost. In particular, the plug socket according to the invention designed in one piece so that the material costs can be minimized. Furthermore the plug socket according to the invention is bent from a single stamped part, which previously punched out of an electrically conductive material, for example a bimetal has been. The manufacture of the plug socket according to the invention is thus opposite the prior art shown in Fig. 3 significantly simplified and cheaper and can especially fully automated.
