Steckverbindung für eine elektrische Verbindung Stand der Technik  Plug connection for an electrical connection prior art
Die vorliegende Erfindung betrifft eine Steckverbindung für eine elektrische Verbindung. The present invention relates to a connector for an electrical connection.
Beispielsweise in der Leistungselektronik werden Kontaktsysteme für trennbare elektrische Verbindungen zwischen Leitungen verwendet. Dabei werden üblicherweise Steckkontaktsysteme mit Federkontakten oder For example, in power electronics contact systems are used for separable electrical connections between lines. In this case, usually plug contact systems with spring contacts or
Schraubverbindungen eingesetzt. Steckkontakte können verdeckt gefügt werden, wobei Schraubverbindungen eine Zugänglichkeit für das Schraubwerkzeug benötigen. Steckkontakte erfüllen jedoch oft nicht die nötigen Screw used. Plug contacts can be joined concealed, with screw connections require accessibility for the screwing. However, plug contacts often do not meet the necessary
Vibrationsanforderungen, z.B. für Steuergeräte bei Getriebe- und Motoranbau in einem Fahrzeug. Dabei ist auch zu beachten, dass die Steckkontaktsysteme nicht beliebig groß gebaut werden können. Im Fahrzeugbereich sollen die Steckkräfte für Handmontage kleiner 75 N betragen. Vibration requirements, e.g. for control units for gearbox and engine mounting in a vehicle. It should also be noted that the plug contact systems can not be built arbitrarily large. In the vehicle area, the insertion forces for manual installation should be less than 75 N.
Das Grundmaterial der Federkontakte von Steckkontaktsystemen hat aufgrund der erforderlichen Federeigenschaften eine schlechte elektrische und thermische Leitfähigkeit. Die Kontaktflächen sind meist punkt- oder linienförmig und dadurch in der Größe auf wenige Quadratmillimeter begrenzt. Wegen der schlechten elektrischen und thermischen Leitfähigkeit und der geringen Kontaktflächen ergibt sich ein elektrischer und thermischer Widerstand, der zu starken The base material of the spring contacts of plug-in contact systems has a poor electrical and thermal conductivity due to the required spring properties. The contact surfaces are usually punctiform or linear and thus limited in size to a few square millimeters. Because of the poor electrical and thermal conductivity and the small contact surfaces results in an electrical and thermal resistance, the strong
Erwärmungen des Kontaktsystems führt. Dadurch wird die Stromtragfähigkeit begrenzt. Die Grenztemperatur für Kontaktsysteme liegt beispielsweise bei 180 °C. Warming of the contact system leads. This limits the current carrying capacity. The limit temperature for contact systems is, for example, 180 ° C.
Offenbarung der Erfindung Im Gegensatz zu Steckkontaktsystemen nach dem Stand der Technik zeigt vorliegende Erfindung eine Steckverbindung, bei der ein Kontaktbolzen großflächig über beinahe den gesamten Umfang mit einer Spannzange in Kontakt kommt (erstes und zweites Ausführungsbeispiel), oder eine Disclosure of the invention In contrast to the prior art plug-in contact systems, the present invention shows a plug-in connection in which a contact pin over a large area over almost the entire circumference with a collet comes into contact (first and second embodiment), or a
Kontakthülse vollflächig über den gesamten Umfang mit einem Spannbolzen inContact sleeve all over the entire circumference with a clamping bolt in
Kontakt kommt (drittes Ausführungsbeispiel). Erfindungsgemäß gibt es dabei keinen Punkt- oder Linienkontakt, sondern einen flächigen Kontakt. Gleichzeitig handelt es sich nicht um einen herkömmlichen Federkontakt, sodass mit sehr geringen Kräften das erfindungsgemäße System gesteckt werden kann. Für das Grundmaterial kann hochleitfähiges Kupfer oder Aluminium verwendet werden, sodass sehr geringe elektrische und thermische Übergangswiderstände entstehen. Eine Relativbewegung zwischen Kontaktbolzen und Spannzange bzw. zwischen Kontakthülse und Spannbolzen aufgrund der Erwärmung wird durch den großen Oberflächenkontakt und die gute Wärmeleitfähigkeit der Grundmaterialien verhindert. Bevorzugt ist hier ein reines Stecksystem, keinContact comes (third embodiment). According to the invention there is no point or line contact, but a flat contact. At the same time, it is not a conventional spring contact, so that the system according to the invention can be plugged with very little force. Highly conductive copper or aluminum can be used for the base material, resulting in very low electrical and thermal contact resistance. A relative movement between the contact pin and collet or between the contact sleeve and clamping bolt due to the heating is prevented by the large surface contact and the good thermal conductivity of the base materials. Preferred here is a pure plug-in system, no
Schraubkontakt , vorgesehen, sodass verdeckt gefügt werden kann, wobei es keiner Zugänglichkeit für ein Werkzeug bedarf. Zwischen den Klemmpartnern erfolgt eine flächige Klemmung, sodass die erfindungsgemäße Steckverbindung hohe Vibrationsbelastungen aushält. Durch die Keilwirkung entstehen große Spannkräfte, durch die selbst Relativbewegungen im μ-Bereich verhindert werden. Des Weiteren ermöglicht die erfindungsgemäße Steckverbindung eine sehr geringe Bauhöhe, da nur eine geringe Fügetiefe erforderlich ist. Screw contact, provided so that can be joined concealed, which requires no accessibility for a tool. Between the clamping partners there is a surface clamping, so that the connector according to the invention withstands high vibration loads. Due to the wedge effect, large clamping forces are generated, which prevent even relative movements in the μ-range. Furthermore, the connector according to the invention allows a very low height, since only a small joint depth is required.
All diese Vorteile werden erreicht durch eine erfindungsgemäße Steckverbindung (die erfindungsgemäße Steckverbindung kann im Rahmen der gesamtenAll these advantages are achieved by a connector according to the invention (the connector according to the invention can in the context of the entire

Dadurch ist gewährleistet, dass der Kontaktbolzen mit seinemconnectable contact pin and connectable to the second line collet. The connector is closed by the contact pin is inserted into the collet. The collet has for this purpose a recess into which the contact pin is inserted. The geometric shape of the recess corresponds to the geometric shape of the contact pin. Further, the outer diameter of the contact pin corresponds to the inner diameter of the recess. This ensures that the contact pin with his
Umfang in der Aussparung anliegt. Die Spannzange weist eine konische Spannzangenaußenfläche auf. In dieser Spannzangenaußenfläche ist zumindest ein Schlitz ausgebildet. Dieser Schlitz wird auch als axialer Schlitz bezeichnet, der sich in Radialrichtung vollständig von der Aussparung durch die die Aussparung umgebende Wandung nach außen erstreckt. Der zumindest eine Schlitz unterteilt den die Aussparung umgebenden Bereich der Spannzange in zumindest einen Spannbacken. Scope rests in the recess. The collet has a conical collet outer surface. In this collet outer surface at least one slot is formed. This slot is also referred to as an axial slot extending in the radial direction completely from the recess through the wall surrounding the recess to the outside. The at least one slot divides the region of the collet surrounding the recess into at least one clamping jaw.
Allgemein betrachtet bilden n Schlitze n Spannbacken, wobei n > 1. Generally speaking, n slots form n jaws, where n> 1.
