Abstract

The plug pin connector (1) to carry a high current, in a motor vehicle electrical system, has a hollow cylindrical end sleeve (20) of defined tolerances around the end surface (12) of the core (11) of the cable (10) with an insulation mantle (14). A portion of the insulation is cut away to give a length of exposed core (13) equal to the length of the sleeve covering it. The sleeve is locked to the core by crimping (30) at a point away from the end surface. The end (26) of the sleeve is flush with the end surface of the core.

Description

Die Erfindung bezieht sich auf eine steckbare Hochstromleitung bzw. einen Hochstromkabelstecker für Hochstromanwendungen.The invention relates to a pluggable high current cable or a high current cable connector for high current applications.

Preferred embodiments of the invention will become apparent from the dependent claims.

Weitere Vorteile, Ziele und Einzelheiten der Erfindung seien im Folgenden anhand der Zeichnung beschrieben.Further advantages, objects and details of the invention are described below with reference to the drawing.

Kurze Beschreibung der Zeichnung:Brief description of the drawing:

  • Figur 1 zeigt eine schematische Schnittansicht eines Ausführungsbeispiels einer erfindungsgemäßen steckbaren Hochstromleitung (Hochstromkabelstecker);Figure 1 shows a schematic sectional view of an embodiment of a plug-in high current line according to the invention (high current cable connector);
  • Figur 2 zeigt eine schematische Schnittansicht einer Kabel- bzw. Gerätedose und zwar ausgebildet mit RADSOK®-Kontakt für die der erfindungsgemäße Kabelstecker insbesondere geeignet ist;Figure 2 shows a schematic sectional view of a cable or device box and that formed with RADSOK® contact for the cable connector according to the invention is particularly suitable;
  • Figur 3 zeigt eine schematische Schnittansicht durch die Kabel- bzw. Gerätedose gemäß Figur 2 und die steckbare Hochstromleitung gemäß Figur.1 und zwar im zusammengesteckten und verriegelten Zustand.FIG. 3 shows a schematic sectional view through the cable or device box according to FIG. 2 and the pluggable high-current line according to FIG. 1, namely in the assembled and locked state.
  • Figur 4 zeigt eine dreidimensionale Ansicht einer erfindungsgemäßen Aderendhülse;FIG. 4 shows a three-dimensional view of a wire end ferrule according to the invention;
  • Figur 5 zeigt eine dreidimensionale Ansicht der steckbaren Hochstromleitung gemäß Figur 1.FIG. 5 shows a three-dimensional view of the pluggable high-current line according to FIG. 1.

In Figur 1 ist eine erfindungsgemäße steckbare Hochstromleitung ein Kabelstecker bzw. Hochstromkabelstecker (Steckpin) 1 dargestellt, die bzw. der aus einem Kabel (Leitung) 10 sowie einer damit verbundenen Aderendhülse 20 besteht. Das Kabel 10 weist einen Leiter 11 sowie einen diesen den umgebenden Isoliermantel 14 auf. Der Leiter bzw, die Ader 11 kann vorzugsweise als Litze ausgebildet sein und aus Aluminium, Kupfer oder einem anderen gut leitenden Material bestehen. Der Leiter 11 weist eine vordere d.h. steckrichtungsseitige Stirnfläche 12 und einen an die Stirnfläche 12 anschließenden abisolierten Bereich 13 auf, in dem der Isoliermantel 14 der Leitung 10 entfernt ist. Die vordere bzw. steckrichtungsseitige Stirnfläche 15 des Isoliermantels 14 dient als Endanschlag 15 beim Einstecken in eine Kabel- bzw. Gerätedose 40.In FIG. 1, a plug-type high-current line according to the invention is shown with a cable plug or high-current cable plug (plug pin) 1, which consists of a cable (line) 10 and a ferrule 20 connected thereto. The cable 10 has a conductor 11 and a surrounding this insulating jacket 14. The conductor or, the core 11 may preferably be formed as a strand and made of aluminum, copper or other highly conductive material. The conductor 11 has a front, i.e. Plug-side end face 12 and a subsequent to the end face 12 stripped region 13, in which the insulating jacket 14 of the line 10 is removed. The front or plug-side end face 15 of the insulating jacket 14 serves as an end stop 15 when plugged into a cable or device box 40th

Auf dem abisolierten Bereich 13 des Leiters 11 wird die Aderendhülse 20 aufgeschoben. Die Aderendhülse 20 besitzt eine zylinderförmige metallische Kontur, wobei der Zylinder innen hohl ist, um einen Aufnahmeraum 29 zur Aufnahme wenigstens eines Teils des abisolierten Bereichs 13 des Leiters 11 zu bilden. Die Aderendhülse 20 weist eine steckrichtungsseitige bzw. vordere Stirnfläche 26, sowie ein leitungsseitige oder auch hintere Stirnfläche 28 auf. An die vordere Stirnfläche 26 schließt sich ein Aderendhülsen-Steckbereich 22 mit definierten Toleranzen an. An den Aufnahmeendhülsen-Steckbereich 22 schließt sich in Richtung der hinteren Stirnfläche 28 ein Crimpbereich bzw. hinterer Bereich 24 an.On the stripped region 13 of the conductor 11, the ferrule 20 is pushed. The ferrule 20 has a cylindrical metallic contour, wherein the cylinder is hollow inside to form a receiving space 29 for receiving at least a portion of the stripped portion 13 of the conductor 11. The ferrule 20 has a plug-side or front end face 26, and a line-side or rear end face 28. The front end face 26 is followed by a wire end sleeve plug-in region 22 with defined tolerances. A crimp area or rear area 24 adjoins the receiving end sleeve plug-in area 22 in the direction of the rear end face 28.

Vorzugsweise weist die Aderendhülse 20 eine Oberflächenbeschichtung auf. Als Oberflächenbeschichtung kann beispielsweise Zinn, Nickel Gold, Silber verwendet werden. Die Verwendung dieser Oberflächenbeschichtung führt zur verbesserten Stromübertragung und verhindert vorzeitige Korrosion an der Kontaktstelle (Reibkorrosion, elektrochemische Korrosion).Preferably, the ferrule 20 has a surface coating. As the surface coating, for example, tin, nickel, gold, silver can be used. The use of this surface coating leads to improved power transmission and prevents premature corrosion at the contact point (fretting corrosion, electrochemical corrosion).

Die definierten Toleranzen bzw. Abmessungen der Aderendhülse 20 dienen dazu, eine sichere Verbindung und sicheren elektrischen Kontakt mit der Buchse 40 auszubilden.The defined tolerances or dimensions of the ferrule 20 serve to form a secure connection and secure electrical contact with the sleeve 40.

Wie in Figur 1 zu sehen, ist die Länge des abisolierten Bereichs (Abisolierlänge) 13 etwas größer als die Länge der Aderendhülse (Hülsenlänge) 20. Durch diese Differenz der Abisolierlänge des Kabels zur Hülsenlänge ist ein Hinterschnitt 17 ausgebildet. Dieser Hinterschnitt 17 kann zur Verrastung des Hochstromkabelsteckers in einem Gehäuse 42 (im Zusammenhang mit Figur 2 beschrieben) der Kabeldose 40 genutzt werden.As can be seen in FIG. 1, the length of the stripped-off region (stripping length) 13 is slightly greater than the length of the wire end sleeve (sleeve length) 20. This difference between the stripping length of the cable and the sleeve length forms an undercut 17. This undercut 17 can be used for latching the high-current cable plug in a housing 42 (described in connection with FIG. 2) of the cable box 40.

Die vordere Stirnfläche 12 des Leiters 11 und die vordere Stirnfläche 26 der Aderendhülse 20 liegen vorzugsweise in einer Ebene bzw. schließen vorzugsweise bündig ab.The front end surface 12 of the conductor 11 and the front end surface 26 of the ferrule 20 are preferably in a plane or close preferably flush.

Die Aderendhülse 20 ist vorzugsweise durch Crimpen auf dem Leiter 11 befestigt. Durch den Crimpungsvorgang im hinteren Bereich 24 der Aderendhülse 20 bildet sich eine Crimpungsverformung 30, die die Aderendhülse 20 auf dem Leiter 11 hält. Durch die Crimpung tritt auch eine Aufweitung der Aderendhülse 20 an der hinteren Stirnfläche 28 auf, die zu einem radial aufgeweiteten Hülsenende 32 führt. Dies wird auch als Tulpeneffekt bezeichnet.The ferrule 20 is preferably fixed by crimping on the conductor 11. The crimping process in the rear region 24 of the ferrule 20 forms a crimping deformation 30, which holds the ferrule 20 on the conductor 11. The crimping also causes a widening of the wire end sleeve 20 on the rear end face 28, which leads to a radially widened sleeve end 32. This is also known as the tulip effect.

Das durch den Tulpeneffekt aufgeweitete Hülsenende 32 begünstigt die Verrastung des Hochstromkabelstecker 1 in dem Gehäuse 42.The expanded by the tulip effect sleeve end 32 favors the locking of the high current cable connector 1 in the housing 42.

Es sind jedoch auch andere Befestigungsmöglichkeiten der Aderendhülse 20 auf dem Leiter 11 möglich, insbesondere Verlöten bzw. auch Verschweißen.However, there are also other ways of securing the ferrule 20 on the conductor 11 possible, in particular soldering or welding.

Auch eine Kombination zwischen Crimpen und einem Lötprozess beispielsweise einem Plasmalötprozess, der die hier vorhandene freie Zugänglichkeit der Stirnseite 12 des Leiters 11 erfordert, ist möglich.A combination between crimping and a soldering process, for example a plasma soldering process, which requires the available free accessibility of the front side 12 of the conductor 11, is possible.

In Figur 2 ist eine Kabel- bzw. Gerätedose 40 dargestellt, die das Gehäuse 42 sowie einen Steckverbindereinsatz bzw. Buchseneinsatz 44 aufweist.FIG. 2 shows a cable or device socket 40, which has the housing 42 as well as a connector insert or socket insert 44.

Als Buchseneinsatz 44 ist insbesondere der RADSOK-Kontakt geeignet, der nur eine zylinderförmige metallische Kontur als Steckpartner bzw. Stecker benötigt. Eine detaillierte Beschreibung der RADSOK-Buchse findet sich in DE 3702012 A1 .As a female insert 44 in particular the RADSOK contact is suitable, which requires only a cylindrical metallic contour as a partner or connector. A detailed description of the RADSOK socket can be found in DE 3702012 A1 ,

Das Steckverbindergehäuse 42 weist eine Schiebehülse 46 und einen Gehäusekörper 48 auf. Der Gehäusekörper 48 besitzt eine steckerseitige bzw. aufnahmeseitige d.h. vordere Stirnfläche 50 sowie ein der vorderen Stirnfläche 50 entgegengesetzt gelegenes hinteres Ende 52. An der vorderen Stirnfläche 50 befindet sich eine Öffnung 54 zum Einstecken des Hochstromkabelsteckers 1. Im Gehäusekörper 48 ist wenigstens ein Schlitz 56, der sich ausgehend von der vorderen Stirnfläche 50 in Richtung des hinteren Endes 52 erstreckt. Durch diesen Schlitz 56 ist es möglich, die an der vorderen Stirnfläche 50 gelegene Öffnung 54 beim Einsteckvorgang durch den Hochstromkabelstecker 1 aufzuweiten. In die Öffnung 54 ragen Rastmittel 58, die durch wenigstens einen Rasthaken, vorzugsweise jedoch mehrere Rasthaken bzw. einen Rastring, gebildet werden, hinein. Die Rastmittel 58 weisen eine angeschrägte Fläche 60 auf, die die Öffnung 54 nach innen, d.h. in Richtung des hinteren Endes 52 verjüngen bzw. verkleinern. Auf der Innen-, d.h. in Richtung des hinteren Endes 52 gelegenen Seite weisen die Rastmittel 58 eine Rast- bzw. Haltefläche 62 auf.The connector housing 42 has a sliding sleeve 46 and a housing body 48. The housing body 48 has a plug-side or receiving-side ie front end face 50 and a front end face 50 opposite located rear end 52. At the front end face 50 is an opening 54 for insertion of the high current cable connector 1. In the housing body 48 is at least one slot 56, which extends from the front end surface 50 toward the rear end 52. Through this slot 56, it is possible to widen the opening 54 located on the front end face 50 during the insertion process by the high-current cable connector 1. In the opening 54 protrude locking means 58 which are formed by at least one latching hook, but preferably a plurality of latching hooks or a latching ring, into it. The latching means 58 have a tapered surface 60, which taper the opening 54 inwardly, ie in the direction of the rear end 52 or reduce. On the inner side, ie in the direction of the rear end 52, the latching means 58 have a latching or holding surface 62.

Die Schiebehülse 46 ist auf dem Gehäusekörper 48 in Längsrichtung, d.h. in Richtung des vorderen Endes 50 bzw. des hinteren Endes 52 verschiebbar. In Figur 2 ist die Schiebehülse 46 in einer nicht verriegelnden Position gezeigt. In dieser Position können beim Einschieben des Hochstromkabelsteckers 1 in die Kabeldose 40 die Rastmittel 58 nach außen geschoben werden und erlauben somit ein Einführen des Hochstromkabelsteckers 1 in den Buchseneinsatz 44. Die maximale Einstecktiefe wird durch die steckrichtungsseitige Stirnfläche 15 - auch als Endanschlag 15 bezeichnet - des Isoliermantels 14 begrenzt. Dabei steht der Endanschlag 15 am Gehäusekörper 48 an.The sliding sleeve 46 is mounted on the housing body 48 in the longitudinal direction, i. slidable in the direction of the front end 50 and the rear end 52. In Figure 2, the sliding sleeve 46 is shown in a non-locking position. In this position, the locking means 58 can be pushed to the outside during insertion of the high-current cable connector 1 in the cable box 40 and thus allow insertion of the high-current cable connector 1 in the female insert 44. The maximum insertion depth is through the plug-side end face 15 - also referred to as end stop 15 - Insulating jacket 14 limited. In this case, the end stop 15 abuts on the housing body 48.

In Figur 3 ist der Hochstromkabelstecker 1 in die Kabeldose 40 vollständig eingesteckt und die Schiebehülse 46 befindet sich in der verriegelnden Position in Richtung der vorderen Stirnfläche 50 des Gehäusekörpers 48. Die Rastmittel 58 hintergreifen dabei mit der Haltefläche 62 die hintere Stirnfläche 28 der Aderendhülse 20. Der durch die Rastmittel 58 gebildete, eingeengte Bereich der Öffnung 54 entspricht im Wesentlichen dem Durchmesser des Leiters 11. Dadurch ist eine sichere Verriegelung des Hochstromkabelsteckers 1 in der Kabeldose 40 gegeben.In Figure 3, the high current cable connector 1 is completely inserted into the cable box 40 and the sliding sleeve 46 is in the locking position in the direction of the front end face 50 of the housing body 48. The locking means 58 engage behind with the support surface 62, the rear end face 28 of the end sleeve 20th The constricted region of the opening 54 formed by the latching means 58 essentially corresponds to the diameter of the conductor 11. This ensures reliable locking of the high-current cable plug 1 in the cable socket 40.

Figur 4 zeigt eine dreidimensionale Ansicht der zylinderförmigen; insbesondere rohrförmigen Aderendhülse 20.Figure 4 shows a three-dimensional view of the cylindrical; in particular tubular end sleeve 20.

Figur 5 zeigt eine dreidimensionale Darstellung des Steckpins 1. In dieser Darstellung ist das hintere Ende der Aderendhülse durch den Crimpvorgang nicht aufgeweitet dargestellt.Figure 5 shows a three-dimensional representation of the plug pin 1. In this illustration, the rear end of the wire end ferrule is not shown widened by the crimping process.

Durch das Aufbringen einer Aderendhülse mit definierten Toleranzen wird eine Verwendung des Leiters 11 des Kabels 10 als Hochstromkabelstecker 1 möglich. Durch Verwendung, insbesondere eines RADSOK®-Kontakts der nur eine zylinderförmige metallische Kontur als Steckpartner benötigt und vergleichsweise große Toleranzen bei dem Hochstromkabelstecker 1 zulässt, ist es möglich, den Hochstromkabelstecker 1 als abisolierten Leiter 11 mit Aderendhülse 20 vorzusehen. Dadurch entfallen die im Stand der Technik verwendeten Steckerkomponenten. Durch den erfindungsgemäßen Hochstromkabelstecker 1 wird eine Reduzierung des erforderlichen Bauraums, eine Minimierung des Übergangswiderstandes, eine Verbesserung der Wärmeabfuhr und eine Reduktion der Teileanzahl möglich. Dadurch wird eine höhere Leistungsfähigkeit bei geringerem Bauraum und weniger Bauteilen erreicht.By applying a wire end ferrule with defined tolerances, use of the conductor 11 of the cable 10 as a high current cable connector 1 is possible. By using, in particular a RADSOK® contact requires only a cylindrical metallic contour as a partner and allows comparatively large tolerances in the high-current cable connector 1, it is possible to provide the high-current cable connector 1 as a stripped conductor 11 with end sleeve 20. This eliminates those used in the prior art Connector components. By the high-current cable connector 1 according to the invention, a reduction of the required installation space, a minimization of the contact resistance, an improvement in heat dissipation and a reduction in the number of parts is possible. As a result, higher performance is achieved with less installation space and fewer components.

Durch die freie Zugänglichkeit der Stirnseite 12 des Leiters 11 bei der Verwendung der beschriebenen Aderendhülse 20 ist ein Plasmalötprozess an dieser Stirnseite 12 möglich, Insbesondere lassen sich dadurch die einzelnen Litzen des Leiters 11 verbinden, insbesondere auch mit der Aderendhülse 20 und man erreicht dadurch die Ausbildung einer stoffschlüssigen Verbindung, welche an der Stirnseite erzeugt wird.Due to the free accessibility of the end face 12 of the conductor 11 when using the wire end ferrule 20 described a plasma soldering process on this end face 12 is possible, in particular can be the individual strands of the conductor 11 connect, especially with the wire end ferrule 20 and thereby achieves the training a cohesive connection, which is generated on the front side.

Die beschriebene erfindungsgemäße steckbare Hochstromleitung 1 bzw. der Hochstromkabelstecker 1 ist insbesondere in einem Hochstromsteckverbinder für Anwendungen in Kraftfahrzeugen mit entsprechend großen Leitungsquerschnitten geeignet.
