Description

Die Erfindung betrifft eine elektrische Steckverbinderbuchse und ein Verfahren zur Herstellung einer elektrischen Steckverbinderbuchse.The invention relates to an electrical connector socket and a method for producing an electrical connector socket.

In der US 2002/0187686 A1 wird eine Buchse gezeigt mit einem T-förmigen Anschluss sowie die Fertigung eines Lamellenkontaktes, bestehend aus einem Lamellenkäfig und einem gerollten Kontakthalter, die auf komplexe Art und Weise und unter Zuhilfenahme verschiedener Hilfsmittel in einer Art "Sanduhrform" verdreht werden.In the US 2002/0187686 A1 A socket is shown with a T-shaped connection as well as the production of a lamellar contact, consisting of a lamellar cage and a rolled contact holder, which are twisted in a complex manner and with the help of various tools in a kind of "hourglass shape".

Ebenfalls wird in der US 4,657,335 eine Buchse beschrieben, die durch eine relativ-rotatorische Bewegung der Enden eines Lamellenkäfigs in eine Hülse ausgebildet wird. Zur Festlegung des Lamellenkäfigs in der Hülse werden an den jeweiligen Enden der Hülse Ringe übergestülpt.Also in the US 4,657,335 a bushing is described which is formed by a relative rotational movement of the ends of a lamellar cage in a sleeve. To secure the lamellar cage in the sleeve, rings are slipped over the respective ends of the sleeve.

Die US 2003/0068931 A1 zeigt eine elektrische Steckverbinderbuchse umfassend eine im wesentlichen zylindrische Buchsenhülse, die an ihren stirnseitigen Enden mit Ausnehmungen versehen ist, um ein hyperbolisch gedrehten Lamellenkäfig mit seinen Anschlusszungen an bzw. in diesen Ausnehmungen zu befestigen.The US 2003/0068931 A1 shows an electrical connector socket comprising a substantially cylindrical socket sleeve which is provided with recesses at its front ends in order to fasten a hyperbolically rotated lamella cage with its connection tongues to or in these recesses.

Aus der DE 10 2011 105 821 B4 ist ferner eine elektrische Steckverbinderbuchse bekannt mit einer zylindrischen Buchsenhülse, wobei die Buchsenhülse mit einem Aufnahmeraum, in dem ein hyperbolisch gedrehter Lamellenkäfig angebracht ist und die Buchsenhülse über eine erste und zweite Stirnfläche verfügt und der Lamellenkäfig mit Anschlusszungen an der ersten und zweiten Stirnfläche der Buchsenhülse mit dieser formschlüssig verbunden ist und dass in dem Übergangsbereich zwischen der Buchsenhülse und der Anschlusszunge Durchbrüche angebracht sind und dass wenigstens eine der Anschlusszungen des Lamellenkäfigs durch einen der Durchbrüche hindurchragt. DE 10 2012 221384 A1 , DE 10 2006 006845 B3 und US 2003/068931 A1 offenbaren weitere Beispiele für elektrische Steckverbinderbuchsen.From the DE 10 2011 105 821 B4 Furthermore, an electrical connector socket is known with a cylindrical socket sleeve, wherein the socket sleeve has a receiving space in which a hyperbolically rotated lamellar cage is mounted and the socket sleeve has a first and second end face and the lamellar cage is positively connected to the socket sleeve with connection tongues on the first and second end face of the latter and that openings are provided in the transition region between the socket sleeve and the connection tongue and that at least one of the connection tongues of the lamellar cage protrudes through one of the openings. DE 10 2012 221384 A1 , DE 10 2006 006845 B3 and US 2003/068931 A1 reveal further examples of electrical connector sockets.

EP 0922314 B1 offenbart eine elektrische Steckverbinderbuchse nach dem Oberbegriff des Anspruchs 1 und ein Verfahren zur Herstellunng einer elektrischen Steckverbinderbuchse nach Anspruch 8. EP 0922314 B1 discloses an electrical connector socket according to the preamble of claim 1 and a method for producing an electrical connector socket according to claim 8.

Die im Stand der Technik bekannten Lösungen weisen allesamt den Nachteil auf, dass die Fertigung sehr aufwendig ist, insbesondere auch die geometrischen Abmessungen von Hülsen, endseitigen Hülsen und Lamellenkäfigen aufeinander abgestimmt sein müssen. Fertigungsbedingt kommt es zu einem Toleranzfeld, was erhebliche praktische Probleme aufwirft. Regelmäßig müssen Hochpräzisionsrohre eingesetzt werden, da jeweils das Innenrohr des Lamellenkäfigs in die Rohrform der umgebenen Hülse passen muss und ggf. die umgebene Hülse wiederum in eine weitere Hülsenaufnahme eingebracht werden muss und dort befestigt werden muss.The solutions known in the state of the art all have the disadvantage that manufacturing is very complex, in particular the geometric dimensions of sleeves, end sleeves and lamella cages have to be coordinated with one another. Due to manufacturing, there is a tolerance range, which causes considerable practical problems. High-precision tubes must be used regularly, since the inner tube of the lamella cage has to fit into the tube shape of the surrounding sleeve and, if necessary, the surrounding sleeve has to be inserted into another sleeve holder and secured there.

Ein erhebliches Problem stellen solche Kontaktsysteme dar, bei der ein zylinderförmiges, insbesondere zylinderförmig gerolltes Kontaktgitter an beiden endseitigen Bundstegen in der das Kontaktgitter umgebenden Hülse zu befestigen ist und die Toleranzen aufeinander abzustimmen sind.A significant problem is posed by contact systems in which a cylindrical, in particular cylindrically rolled, contact grid has to be fastened to both end flanges in the sleeve surrounding the contact grid and the tolerances have to be coordinated with one another.

In der Regel umfassen daher gattungsgemäße Steckverbinderbuchsen ein eingesetztes Kontaktgitter, welches mittels aufwendiger materialschlüssiger Fügeverfahren (wie z. B. Schweißen) mit der Hülse verbunden ist. Dennoch ist regelmäßig ein Präzisionsrohr erforderlich, um zumindest den Innendurchmesser in einem kleineren Toleranzfeld zu haben. Andererseits unterliegen das Kontaktgitter und die typischerweise daran ausgebildeten Bundstege dennoch solchen Fertigungstoleranzen, dass es fertigungstechnische Schwierigkeiten bei den herkömmlichen Fügeverfahren gibt.As a rule, generic connector sockets therefore include an inserted contact grid, which is connected to the sleeve using complex material-locking joining processes (such as welding). Nevertheless, a precision tube is regularly required in order to at least have the inner diameter within a smaller tolerance range. On the other hand, the contact grid and the collars typically formed on it are subject to such manufacturing tolerances that there are manufacturing difficulties with conventional joining processes.

Aufgabe der vorliegenden Erfindung ist es daher, vorbesagte Nachteile zu überwinden und eine Steckverbinderbuchse unter Inkaufnahme von ggf. höheren Toleranzen wesentlich einfacher und wirtschaftlicher zu fertigen, wobei gleichzeitig die Anzahl der Bauteile reduziert werden soll, aber dennoch eine hohe Stromtragfähigkeit bei hoher Temperaturbelastung gewährleistet ist, insbesondere bei Temperaturen zwischen 150° und 170° und teilweise bei höheren Temperaturen sicher gewährleistet sein muss.The object of the present invention is therefore to overcome the aforementioned disadvantages and to manufacture a connector socket in a much simpler and more economical manner, accepting possibly higher tolerances, while at the same time reducing the number of components, but nevertheless ensuring a high current-carrying capacity under high temperature loads, in particular at temperatures between 150° and 170° and partly at higher temperatures.

Die Erfindung wird durch eine Steckverbinderbuchse mit den Merkmalen von Anspruch 1 sowie einem Verfahren nach den Merkmalen von Anspruch 8 gelöst.The invention is solved by a connector socket with the features of claim 1 and a method according to the features of claim 8.

Die Grundidee der vorliegenden Erfindung ist es dabei, den zylinderförmigen Lamellenkäfig nicht wie im Stand der Technik bekannt an einem oder beiden Enden mit einem Fügeverfahren (wie z.B. Schweißen) zu fügen, sondern am ersten Ende des Lamellenkäfigs Ausnehmungen vorzusehen, in die Auswölbungen der Hülse mittels einer Prägeverbindungen hineingeformt werden, um den Lamellenkäfig in der Hülse zu fixieren, dann den Lamellenkäfig ggf. um einem bestimmten Winkel zu tordieren (um daraus einen hyperbolisch geformten Lamellenkäfig auszubilden) und in einem weiteren Schritt Auswölbungen der Hülse mittels weiterer Prägeverbindungen in Ausnehmungen, die am anderen Ende der Hülse vorgesehen sind hineinzuformen.The basic idea of the present invention is not to join the cylindrical laminar cage at one or both ends using a joining process (such as welding), as is known in the prior art, but to provide recesses at the first end of the laminar cage, into which bulges of the sleeve are formed by means of a stamped connection in order to fix the laminar cage in the sleeve, then to twist the laminar cage, if necessary, by a certain angle (in order to form a hyperbolically shaped laminar cage) and, in a further step, to form bulges of the sleeve into recesses provided at the other end of the sleeve by means of further stamped connections.

Erfindungsgemäß ist daher eine elektrische Steckverbinderbuchse umfassend eine zylindrische Buchsenhülse vorgesehen, wobei die Buchsenhülse mit einem Aufnahmeraum ausgebildet ist, in dem ein zylinderförmiger Lamellenkäfig mit einer Vielzahl von parallel verlaufenden Kontaktlamellen eingeschoben ist, wobei der Lamellenkäfig über einen ersten und zweiten endseitige umlaufenden Bundsteg verfügt zwischen denen die Kontaktlamellen verlaufen, wobei der Lamellenkäfig an beiden Bundstegen über fensterartige Ausnehmungen verfügt und wobei durch ein Prägeverfahren mehrere Auswölbungen in den Mantel der Buchsenhülse eingebracht sind, die sich in die fensterartigen Ausnehmungen derart hinein erstrecken, dass eine kraftschlüssige Verbindung zwischen dem Lamellenkäfig und der Buchsenhülse gebildet wird.According to the invention, an electrical connector socket comprising a cylindrical socket sleeve is therefore provided, wherein the socket sleeve is formed with a receiving space into which a cylindrical lamellar cage with a plurality of parallel contact lamellae is inserted, wherein the lamellar cage has a first and second end-side circumferential collar web between which the contact lamellae run, wherein the lamellar cage has window-like recesses on both collar webs and wherein a plurality of bulges are introduced into the jacket of the socket sleeve by means of an embossing process, which extend into the window-like recesses in such a way that a force-fitting connection is formed between the lamellar cage and the socket sleeve.

In einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass am ersten und zweiten Bundsteg zwei oder mehrere fensterartige Ausnehmungen oder Öffnungen am Rand des jeweiligen Bundstegs so angeordnet sind, dass die jeweilige Ausnehmung stirnseitig zum jeweiligen Rand hin offen ist und vorzugsweise als eine stirnseitige Verzahnung geformt oder gebildet ist.In an advantageous embodiment of the invention, it is provided that on the first and second gutter web, two or more window-like recesses or openings are arranged at the edge of the respective gutter web in such a way that the respective recess is open on the front side towards the respective edge and is preferably shaped or formed as a front-side toothing.

Weiter vorteilhaft ist es, wenn am ersten und zweiten Bundsteg zwei oder mehrere fensterartige Ausnehmungen oder Öffnungen mit je einer in Axialrichtung (A) betrachteten Länge L vorgesehen sind, in die an einer Innenwand der Buchsenhülse jeweils vorgesehene Auswölbungen einer jeweils nahezu identischen Länge L' eingreifen, so dass dadurch eine axiale Bewegung des jeweiligen Bundsteges verhindert wird.It is further advantageous if two or more window-like recesses or openings, each with a length L viewed in the axial direction (A), are provided on the first and second flange webs, into which bulges of a virtually identical length L' provided on an inner wall of the bushing sleeve engage, so that an axial movement of the respective flange web is thereby prevented.

In einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass am ersten und zweiten Bundsteg fensterartige Ausnehmungen mit einer quer zur Axialrichtung (A) betrachteten Breite B vorgesehen sind, in die an einer Innenwand der Buchsenhülse vorgesehene Auswölbungen einer gleichen oder fast gleichen Breite B' eingreifen, so dass ein Verdrehen des jeweilige Bundstegs verhindert wird.In an advantageous embodiment of the invention, window-like recesses with a width B viewed transversely to the axial direction (A) are provided on the first and second flange webs, into which bulges of the same or almost the same width B' provided on an inner wall of the bushing sleeve engage, so that twisting of the respective flange web is prevented.

Weiter vorteilhaft ist es, wenn Befestigungsmittel an der Buchsenhülse als Prägungen im Mantel der Buchsenhülse vorgesehen sind, wobei am Außenmandel der Buchsenhülse Vertiefungen und am Innenmantel der Buchsenhülse hervorstehende Auswölbungen ausgebildet sind.It is further advantageous if fastening means on the socket sleeve are provided as embossings in the jacket of the socket sleeve, with depressions being formed on the outer flange of the socket sleeve and protruding bulges being formed on the inner jacket of the socket sleeve.

In einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass Befestigungsmittel als im Wesentlichen quaderförmige Aufwölbungen mit jeweils zwei gegenüberliegenden Längsseitenkanten und jeweils zwei gegenüberliegenden Querseitenkanten ausgebildet sind. Weiter vorteilhaft ist es, wenn der Lamellenkäfig in einem zentralen mittigen Abschnitt in Axialrichtung (A) betrachten einen geringeren Durchmesser aufweist, als an den Bundestegen, vorzugsweise dadurch gebildet, dass der eine Bundsteg des Lamellenkäfigs gegenüber dem anderen Bundsteg tordiert wurde.In an advantageous embodiment of the invention, it is provided that fastening means are designed as essentially cuboid-shaped bulges, each with two opposite longitudinal side edges and two opposite transverse side edges. It is also advantageous if the lamella cage has a smaller diameter in a central middle section, viewed in the axial direction (A), than at the flanges, preferably formed by twisting one flange of the lamella cage relative to the other flange.

Ein weiterer Aspekt der vorliegenden Erfindung betrifft ein Verfahren zur Herstellung einer wie zuvor beschriebenen elektrischen Steckverbinderbuchse, mit den folgenden Verfahrensschritten:

  1. a. Herstellen eines Kontaktlamellengitters mit zwei endseitigen Bundstegen mit einer Vielzahl von dazwischen verlaufenden parallelen Kontaktlamellen;

  5. e. Anbringen von in den Aufnahemraum hervorstehenden weiteren Auswölbungen an dem Innenmantel der Buchsenhülse durch Prägen korrespondierend zu den Ausnehmungen des zweiten Bundstegs derart, dass die entsprechenden 2. geprägten Auswölbungen kraftschlüssig in die fensterartigen Öffnungen am zweiten Bundsteg eingreifen und diesen festlegen.

  1. a. Manufacturing a contact lamella grid with two end flanges with a plurality of parallel contact lamellas running between them;
  2. b. Inserting two or more window-like openings open at the front into the two flanges of the contact lamella grid and transferring the contact lamella grid into a cylindrical lamella cage,
  3. c. Providing a bushing sleeve with a receiving space and inserting the laminar cage into the receiving space;
