Description

Elektrischer'Steckverbinder, Verfahren zu seinem Anschluß und Vorrichtung zur Durchführung des Verfahrens.Electrical connector, method for its connection and device for carrying out the method.

Die Erfindung betrifft einen elektrischen Steckverbinder mit einem Kontaktabschnitt, der mit einem Abschnitt eines mehrdrähtigen Leiters verbunden ist, sowie ein Verfahren zum Anschluß dieses Steckverbinders und eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to an electrical connector with a contact section which is connected to a section of a multi-wire conductor, and to a method for connecting this connector and a device for carrying out the method.

Derartige Steckverbinder finden Anwendung bei der Verdrahtung von elektrischen und elektronischen Geräten und An- - lagen, insbesondere auch in Hausgeräten und Automobilen. An die Verbindung zwischen dem Steckverbinder und dem Draht werden insbesondere zwei Anforderungen gestellt: Zum ersten soll der elektrische Übergangswiderstand gleichbleibend gering sein. Zum zweiten soll die Verbindungsstelle auf Zug hochbelastbar sein.Such connectors are used in the wiring of electrical and electronic devices and systems, in particular also in household appliances and automobiles. There are two particular requirements for the connection between the connector and the wire: First, the electrical contact resistance should be consistently low. Secondly, the connection point should be able to withstand high loads on the train.

Es ist bekannt, einen elektrischen Steckverbinder mit dem Draht zu verlöten, zu verschweißen oder mittels Krimpen auf diesen aufzupressen (anzuschlagen). Es ist auch schon eine Vorrichtung bekannt geworden, mittels der die Verbindung durch Kombination von Verschweißen und Anschlagen hergestellt wird, siehe DE-OS 27 22 552. Eine Schweißverbindung kann jedoch in der Regel nur bei gleichartigen zu verbindenden Metallen erfolgen, und der werkzeugmäßige Aufwand ist beachtlich. Schließlich ist es bekannt, verzinnte Litzen an ein Kontaktteil anzuschlagen.It is known to solder an electrical connector to the wire, to weld it or to press it onto it (by crimping). A device has also become known, by means of which the connection is made by combining welding and striking, see DE-OS 27 22 552. However, a welded connection can generally only be made with metals of the same type to be connected, and the tooling effort is considerable remarkable. Finally, it is known to attach tinned strands to a contact part.

Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder zu schaffen, bei dem die Vorteile des Lötens und des Anschlagens miteinander verbunden sind. Hierzu schlägt die Erfindung vor, daß der Kontaktabschnitt in mindestens ein Paar Lappen geteilt ist, das den Leiter umfaßt, daß zwischen den um den Leiter gebogenen Lappen mindestens eine öffnung als Zugang zum Leiter angeordnet ist und daß die Lappen mit dem Leiter verlötet sind. Die Öffnung kann sich quer zur Längsachse oder in Richtung der Längsachse des Steckverbinders erstrecken. Ein Verfahren zur Herstellung einer elektrischen Verbindung mit einem elektrischen Steckverbinder sieht vor, daß ein Stück Lötdraht zwischen die Lappen geklemmt wird, daß das oder die Paar Lappen um den Leiter gebogen werden und daß der Steckverbinder und/oder der Leiter im Bereich des Zwischenraumes erhitzt wird. Bei einer Vorrichtung zur Durchführung des vorgenannten Verfahrens erfolgt die Erhitzung durch an dem Kontaktabschnitt und/oder dem Leiter anliegende Elektroden.The invention has for its object to provide a connector in which the advantages of soldering and of attachment are connected to each other. For this purpose, the invention proposes that the contact section is divided into at least one pair of tabs that surround the conductor, that at least one opening is arranged between the tabs bent around the conductor as an access to the conductor, and that the tabs are soldered to the conductor. The opening can extend transversely to the longitudinal axis or in the direction of the longitudinal axis of the connector. One method of making an electrical connection with an electrical connector is to clamp a piece of solder wire between the tabs, to bend the pair or tabs around the conductor, and to heat the connector and / or conductor in the space . In the case of a device for carrying out the aforementioned method, the heating is carried out by electrodes resting on the contact section and / or the conductor.

Ein anderes Verfahren zur Herstellung einer elektrischen Verbindung mit einem-Steckverbinder nach der Erfindung sieht vor, daß das oder die Paar Lappen um den Leiter gebogen werden und daß durch den Zwischenraum erhitztes, flüssiges Lot auf den Leiter aufgetropft wird. Eine Vorrichtung zur Durchführung des vorgenannten Verfahrens sieht vor, daß eine elektrische Spule zur Aufnahme und zur Erhitzung eines Lötdrahtes dient.Another method of making an electrical connection with a connector according to the invention provides that the pair or tabs are bent around the conductor and that liquid solder heated through the space is dripped onto the conductor. A device for performing the aforementioned method provides that an electrical coil is used to receive and heat a solder wire.

Die erfindungsgemäßen Verbindungen zeigen sehr kleine elektrische Übergangswiderstände und sind auf Zug hoch belastbar. Die Korrosionsgefahr ist gering, und die beiden Verfahrenstechniken Krimpen und Löten lassen sich hier vorrichtungsmäßig gut kombinieren. Insbesondere wird vermieden, daß Lot bis zur Steckbuchse oder dergl. wandert und die ordnungsgemäße Steckverbindung beeinträchtigt.The connections according to the invention show very small electrical contact resistances and are highly resilient under tension. The risk of corrosion is low, and the two process technologies crimping and soldering can be combined well in terms of device. In particular, it is avoided that solder migrates to the socket or the like and impairs the correct plug connection.

In der Zeichnung sind zwei Ausführungsbeispiele von erfindungsgemäßen Steckverbindern dargestellt, die anhand zweier möglicher Verfahren mit einem Litzenleiter verbunden werden.

  • Figur 1 zeigt einen ersten elektrischen Steckverbinder nach der Erfindung, in dessen Anschlußbereich ein Stück Lötdraht eingeklemmt ist.
  • Figur 2 zeigt den elektrischen Steckverbinder nach Figur 1, dessen Anschlußbereich - nachdem er mitsamt dem Stück Lötdraht an ein Endstück einer Litze angeschlagen wurde - mit Hilfe einer elektrischen Widerstands-Lötvorrichtung erhitzt wird.
  • Figur 3 zeigt den Steckverbinder nach Figur 1, der jedoch zunächst ohne Lötdraht an ein Endstück einer Litze angeschlagen wurde, wobei ein Lötdraht nun mit Hilfe einer elektrischen Induktivität zum Schmelzen gebracht wird, so daß flüssiges Lot in den Anschlußbereich eindringt.
  • Figur 4 zeigt einen zweiten Steckverbinder, bei dem eine Litze im rechten Winkel zu seiner Längsachse angebracht werden soll und in dessen Anschlußbereich ein Stück Lötdraht eingeklemmt ist.
  • Figur 5 zeigt die Anwendung einer Lötvorrichtung bei dem zweiten Steckverbinder entsprechend der Figur 2.
  • Figur 6 zeigt die Ansicht A in Figur 4, also die Ansicht auf den Anschlußbereich des zweiten Steckverbinders mit einem eingeklemmten Stück Lötdraht.
The drawing shows two exemplary embodiments of plug connectors according to the invention, which are connected to a stranded conductor using two possible methods.
  • Figure 1 shows a first electrical connector according to the invention, in the connection area a piece of solder wire is clamped.
  • Figure 2 shows the electrical connector according to Figure 1, the connection area - after it was struck together with the piece of solder wire to an end piece of a strand - is heated with the aid of an electrical resistance soldering device.
  • FIG. 3 shows the plug connector according to FIG. 1, which, however, was first struck on an end piece of a strand without a solder wire, a solder wire now being melted with the aid of an electrical inductor, so that liquid solder penetrates into the connection area.
  • Figure 4 shows a second connector in which a strand is to be attached at right angles to its longitudinal axis and in the connection area a piece of solder wire is clamped.
  • FIG. 5 shows the use of a soldering device in the second connector corresponding to FIG. 2.
  • FIG. 6 shows view A in FIG. 4, that is, the view of the connection area of the second connector with a clamped-in piece of solder wire.

Der Steckverbinder 1 ist im Ausführungsbeispiel als Steckbuchse 2 mit einer Krimp-Kralle 3 aus Metallblech gestanzt und gebogen. Die Krimp-Kralle 3 dient zum Anschluß an einen abisolierten Endabschnitt 4 eines mit einer Isolierung 5 versehenen Litzenleiters 6. Die Krimp-Kralle 3 weist zwei Paar Lappen 7 und 8 auf, zwischen denen je ein Zwischenraum 9 und 10 vorgesehen ist. Die Längsachse der Krimp-Kralle 3 stimmt hier mit der Längsachse der Steckbuchse 2 überein, sie ist mit x-x bezeichnet. Daß dies nicht immer der Fall sein muß, ist zum Beispiel zu den Figuren 4 bis 6 beschrieben. Die Zwischenräume 9 und 10 erstrecken sich etwa rechtwinklig zur Längsachse x-x; eine andere Anordnung, zum Beispiel im Winkel von 45°, ist ebenfalls möglich. In die Zwischenräume 9 und 10 ist ein Stück Lötdraht 11 eingeklemmt.The connector 1 is stamped and bent in the exemplary embodiment as a socket 2 with a crimp claw 3 from sheet metal. The crimping claw 3 is used to connect to a stripped end section 4 of a stranded conductor 6 provided with insulation 5. The crimping claw 3 has two pairs of tabs 7 and 8, between each of which a space 9 and 10 is provided. The longitudinal axis of the crimp claw 3 coincides here with the longitudinal axis of the socket 2, it is denoted by x-x. That this does not always have to be the case is described, for example, in FIGS. 4 to 6. The spaces 9 and 10 extend approximately at right angles to the longitudinal axis x-x; another arrangement, for example at an angle of 45 °, is also possible. A piece of solder wire 11 is clamped into the spaces 9 and 10.

In die Krimp-Kralle 3 wird nun der Endabschnitt 4 des Litzenleiters 6 eingelegt und zusammen mit dem Stück Lötdraht 11 durch Verformung der Krimp-Kralle 3 an den Steckverbinder 1 angekrimpt (angeschlagen). Das Ergebnis ist in Figur 2 zu erkennen. Die Enden des Stück Lötdrahtes 11 ragen aus den Zwischenräumen 9 und 10 heraus; sie sind hier etwa 5 Millimeter lang.The end section 4 of the stranded conductor 6 is now inserted into the crimping claw 3 and, together with the piece of solder wire 11, is crimped (struck) to the plug connector 1 by deforming the crimping claw 3. The result can be seen in Figure 2. The ends of the piece of solder wire 11 protrude from the spaces 9 and 10; here they are about 5 millimeters long.

Sodann wird die Krimp-Kralle 3 zwischen zwei Elektroden 12 und 13 gebracht. Der untere Brückenteil 3a der Krimp-Kralle 3 liegt dabei auf der Elektrode 12 auf, während die Elektrode 13 zwischen den Lappenpaaren 7 und 8 hindurch im Bereich der Zwischenräume 9 und 10 unmittelbar auf den Abschnitt 4 des Litzenleiters 6 drückt. In Folge der elektrischen Widerstandserhitzung des Bereiches zwisschen den Elektroden 12 und 13 schmilzt der Lötdraht 4. Es ist dabei eine Art Kapillarwirkung zu erkennen: Die Enden des Stück Lötdrahtes 11 werden in den Litzen-Abschnitt 4 "hineingesaugt" und füllen dort die Zwischenräume der Litze 6 aus. Die Folge ist eine homogene Verbindung zwischen der Litze 6 und der Krimp-Kralle 3.Then the crimp claw 3 is placed between two electrodes 12 and 13. The lower bridge part 3a of the crimping claw 3 lies on the electrode 12, while the electrode 13 presses directly between the flap pairs 7 and 8 in the region of the spaces 9 and 10 onto the section 4 of the stranded conductor 6. As a result of the electrical resistance heating of the area between the electrodes 12 and 13 melts the solder wire 4. A kind of capillary effect can be seen: The ends of the piece of solder wire 11 are "sucked" into the strand section 4 and fill the spaces between the strands 6 there. The result is a homogeneous connection between the strand 6 and the crimp claw 3.

In Figur 3 ist der gleiche Steckverbinder 1 wie in Figur 1 dargestellt. Jedoch wurde hier die Krimp-Kralle 3 zunächst ohne Lötdraht an eine Litze 6' angeschlagen. Von oben wird ein Endabschnitt eines Lötdrahtes 11' senkrecht in Richtung auf den Abschnitt 4' der Litze 6' herangeführt, der in den Zwischenräumen 9 und 10 zwischen den Lappenpaaren 7 und 8 unisoliert freiliegt. Oberhalb der Krimp-Kralle 3 ist eine Spule 14 angeordnet, die den Lötdraht 11' induktiv erwärmt, so daß das Lot in Form von Tropfen durch die Zwischenräume 9 und 10 auf den Abschnitt 4' der Litze 6' fällt. Das Lot dringt dabei in die Litze 6' ein und füllt alle vorhandenen Zwischenräume aus. Die Folge ist eine homogene Verbindung zwischen der Litze 6' und der Krimp-Kralle 3.In Figure 3, the same connector 1 is shown as in Figure 1. However, the crimping claw 3 was first struck on a strand 6 'without solder wire. From above, an end section of a solder wire 11 'is brought vertically in the direction of the section 4' of the strand 6 ', which is exposed in the spaces 9 and 10 between the pairs of tabs 7 and 8 without insulation. A coil 14 is arranged above the crimping claw 3, which inductively heats the solder wire 11 ', so that the solder falls in the form of drops through the spaces 9 and 10 onto the section 4' of the strand 6 '. The solder penetrates into the strand 6 'and fills in all the spaces in between. The result is a homogeneous connection between the strand 6 'and the crimp claw 3.

In den Figuren 4 bis 6 ist ein Steckverbinder 21 mit einer Steckbuchse 22 dargestellt, bei dem die Längsachse x'-x' der Krimp-Kralle 23 senkrecht zur Achse X xnder Steckbuchse 22 verläuft; sie könnte in einem anderen Anwendungsfalle auch in einem Winkel von zum Beispiel 45 oder 60° hierzu verlaufen. Die Krimp-Kralle 23 ist bestimmt zum Anschlagen an einen Endabschnitt 24 eine isolierten Litze. Hierzu ist an der Krimp-Kralle 23 ein Lappenpaar 25 angeordnet, das sich nahezu senkrecht zur Achse x-x und zur Achse x'-x' erstreckt. Die Krimp-Kralle 23 ist zum besseren Einrollen an den Enden 26 des Lappenpaares 25 etwas in Richtung zu der Steckbuchse 22 hin abgebogen. Zwischen das Lappenpaar 25 ist in dem Zwischenraum 27 ein Stück Lötdraht 28 geklemmt.FIGS. 4 to 6 show a plug connector 21 with a socket 22, in which the longitudinal axis x'-x 'of the crimping claw 23 extends perpendicular to the axis X x n of the socket 22; in another application, it could also run at an angle of, for example, 45 or 60 ° to it. The crimping claw 23 is intended for attachment to an end section 24 of an insulated wire. For this purpose, a pair of tabs 25 is arranged on the crimp claw 23, which extends almost perpendicular to the axis xx and the axis x'-x '. The crimping claw 23 is bent slightly at the ends 26 of the pair of flaps 25 in the direction of the socket 22 for better rolling. Between the pair of rags 25, a piece of solder wire 28 is clamped in the intermediate space 27.

In die Krimp-Kralle 23 wird nun ein abisolierter Endabschnitt 24 (oder Zwischenabschnitt) eines Litzenleiters eingebracht und durch Einrollen der Lappen 25 zusammen mit dem Stück Lötdraht 28 an den Steckverbinder 21 angeschlagen. Das Ergebnis ist in Figur 5 zu erkennen. Ein Ende des Lötdrahtes 28 ragt aus dem Zwischenraum 27 der Krimp-Kralle 23 heraus. Wie schon zur Figur 2 beschrieben, wird nun die Lötstelle erhitzt und der Lötdraht 28 zieht sich in die Litze 24. Die Folge ist eine homogene Verbindung zwischen der Litze 24 und der Krimp-Kralle 23.A stripped end section 24 (or intermediate section) of a stranded conductor is now introduced into the crimping claw 23 and struck on the plug connector 21 together with the piece of soldering wire 28 by rolling in the tabs 25. The result can be seen in FIG. 5. One end of the solder wire 28 protrudes from the space 27 of the crimping claw 23. As already described for FIG. 2, the solder joint is now heated and the solder wire 28 pulls into the strand 24. The result is a homogeneous connection between the strand 24 and the crimping claw 23.

Eine weitere Möglichkeit, den Steckverbinder 21 zu verlöten, ist schon zur Figur 3 beschrieben worden: In den Zwischenraum 27 wird flüssiges Lot getropft.Another possibility for soldering the plug connector 21 has already been described for FIG. 3: liquid solder is dripped into the intermediate space 27.

Zwei mögliche Anordnungen der Krimp-Kralle, zwei mögliche Verfahren und zwei Vorrichtungen hierzu sind ausführlich beschrieben worden. Jedoch sind diese zwar als vorteilhafte, aber auch nur als beispielhafte Ausführungen der Erfindung zu verstehen. So kann die öffnung nicht nur als offener Schlitz, sondern z.B. auch als Langloch ausgebildet sein, das z.B. im Brückenteil 3a der Krimp- kralle 3 angeordnet ist. In diesem Fall ist der Zwischenraum nur auf die andere Seite der Krimpkralle 3 verlegt worden.Two possible arrangements of the crimp claw, two possible methods and two devices for this have been described in detail. However, these are to be understood as advantageous, but also only as exemplary embodiments of the invention. So the opening can not only be an open slot, but e.g. also be designed as an elongated hole, e.g. the crimp claw 3 is arranged in the bridge part 3a. In this case, the space has only been moved to the other side of the crimp claw 3.
