Description

Die Erfindung betrifft einen Flachkontakt, mit einem Messerkontaktabschnitt, der zur Aufnahme in einem geeigneten Kontaktfederpaar eines Gegensteckverbinders ausgebildet ist, und mit Federarmen zur Dämpfung von Relativbewegungen zwischen dem Messerkontaktabschnitt und einem solchen Kontaktfederpaar, wobei die Federarme einstückig an die langen Schmalseiten des Flachkontakts angeformt sind.The invention relates to a flat contact, with a blade contact section which is designed to be received in a suitable contact spring pair of a mating connector, and with spring arms for damping relative movements between the blade contact section and such a contact spring pair, wherein the spring arms are integrally formed on the long narrow sides of the flat contact.

Ein derartiger Flachkontakt ist aus der deutschen Offenlegungsschrift DE 10 2011 076 506 A1 bekannt.Such a flat contact is known from the German publication EN 10 2011 076 506 A1 known.

Viele elektrische Steckverbinder, die unter anderem als Flachkontakt ausgebildet sein können, werden unter schwierigen Umweltbedingungen eingesetzt. Werden Steckverbinder etwa in Kraftfahrzeugen verwendet, so sind sie häufig neben wechselnden Temperaturen auch aggressiven Gasen und Dämpfen, sowie auch Vibrationsbelastungen ausgesetzt.Many electrical connectors, which can be designed as flat contacts, are used under difficult environmental conditions. If connectors are used in motor vehicles, for example, they are often exposed to changing temperatures, aggressive gases and vapors, and vibrations.

Durch Vibrationen einerseits, sowie auch aufgrund von thermischen Längenausdehnungen aufgrund wechselnder Temperaturen andererseits ergeben sich Relativbewegungen zwischen miteinander verbundenen Kontakten. Bekannt ist das Phänomen der Reibkorrosion. Durch Relativbewegungen, die die Kontakte von miteinander verbundenen Steckverbinderteilen gegeneinander ausführen, werden die Kontaktoberflächen mechanisch und, unter entsprechenden Umweltbedingungen, auch chemisch belastet und angegriffen. Dadurch verschlechtern sich die elektrischen Eigenschaften der Kontakte, oftmals bis hin zum Funktionsausfall.Vibrations on the one hand and thermal expansion due to changing temperatures on the other hand result in relative movements between connected contacts. The phenomenon of fretting corrosion is well known. The relative movements that the contacts of connected connector parts make against each other cause the contact surfaces to be mechanically and, under certain environmental conditions, chemically stressed and attacked. This causes the electrical properties of the contacts to deteriorate, often to the point of failure.

Aus der deutschen Gebrauchsmusterschrift DE 299 06 652 U1 ist eine Steckverbinderanordnung bekannt, bestehend aus einem Flachkontakt in Form eines Messerkontakts und einem buchsenartigen Federarmkontaktelement. An die den Flachkontakt kontaktierenden Federkontaktarmen des Federarmkontaktelements sind Federschenkel einer mechanisch steifen Überfeder gekoppelt, die den Flachkontakt zusätzlich klemmend halten, und die dadurch durch externe Vibrationen verursachte Relativbewegungen zwischen dem Flachkontakt und den Federkontaktarmen des Federarmkontaktelements unterbinden sollen.From the German utility model specification DE 299 06 652 U1 A connector arrangement is known, consisting of a flat contact in the form of a blade contact and a socket-like spring arm contact element. Spring legs of a mechanically stiff overspring are coupled to the spring contact arms of the spring arm contact element that contact the flat contact, which additionally hold the flat contact in a clamping manner and are intended to prevent relative movements between the flat contact and the spring contact arms of the spring arm contact element caused by external vibrations.

Die hier buchsenseitig vorgesehenen Maßnahmen zur Verhinderung von Relativbewegungen zwischen den Kontaktelementen, und damit von Reibkorrosion, erfordern durch die vorgesehene Überfeder einen zumindest zweiteiligen Aufbau des Federarmkontaktelements und damit einen relativ hohen Kosten- und Montageaufbau.The measures provided here on the socket side to prevent relative movements between the contact elements, and thus frictional corrosion, require a construction of at least two parts of the spring arm contact element due to the provided overspring and thus a relatively high cost and assembly structure.

Es stellte sich die Aufgabe, einen besonders einfachen und kostengünstigen Flachkontakt zu schaffen, die nur wenig anfällig für Reibkorrosion ist.The task was to create a particularly simple and cost-effective flat contact that is only slightly susceptible to fretting corrosion.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Endabschnitte der Federarme als in einer Kontaktkammer verschiebbar lagerbare Rasthaken ausgebildet sind.This object is achieved according to the invention in that the end sections of the spring arms are designed as locking hooks that can be displaceably mounted in a contact chamber.

In der vorgenannten Druckschrift DE 10 2011 076 506 A1 gibt es keinen Hinweis auf diese Lösung. Dieses Dokument zeigt zwar zwei Federarme, die einstückig an die langen Schmalseiten eines Flachkontakts angeformt sind, jedoch keine Endanschnitte und damit insbesondere keine als Rasthaken ausgebildete Endabschnitte.In the above-mentioned publication EN 10 2011 076 506 A1 There is no reference to this solution. This document shows two spring arms that are integrally formed on the long narrow sides of a flat contact, but no end cuts and therefore in particular no end sections designed as locking hooks.

Der erfindungsgemäße Flachkontakt weist ein paar angeformte Federarme auf, welche sowohl in Längsrichtung als auch in den beiden Querrichtungen auf den Flachkontakt einwirkenden Vibrationen ausgleichen können.The flat contact according to the invention has a pair of molded spring arms which extend both in the longitudinal direction and in the two transverse directions can compensate for vibrations acting on the flat contact.

Die Federarme lassen Bewegungen in Längsrichtung zu um Relativbewegungen in dieser Richtung auszugleichen. Zudem lassen sie eine Taumelbewegung zu, die dazu geeignet sind, die Lötstellen des Gegenkontaktes zu entlasten.The spring arms allow movements in the longitudinal direction to compensate for relative movements in this direction. They also allow a wobbling movement, which is suitable for relieving the soldering points of the counter contact.

Der Flachkontakt erfüllt auf vorteilhafte Weise zugleich die folgenden Anforderungen:

  • gute Leitung von elektrischem Strom,
  • Ausgleich von Längenausdehnungen und Vibrationen des Gesamtsystems, damit diese nicht die Kontaktstelle verschieben und damit zu einer Schädigung der Kontaktstelle durch Reibkorrosion führen,
  • Minimierung von Kräften, die dauerhaft auf Lötstellen (die in THT- oder SMD-Technik ausgeführt sein können) des Kontaktpartners des Flachkontakts anstehen und diese Lötverbindungen über die Zeit beanspruchen und schädigen können,
  • Ausgleich von Toleranzen des Gesamtsystems, damit diese keine Kraftwirkung auf den Kontaktpartner des Flachkontakts und dessen Lötstellen erzeugen,
  • Positionierung des Flachkontaktes zum Kontaktpartner beim Steckvorgang,
  • einfache Montage des Flachkontakts.
The flat contact advantageously meets the following requirements at the same time:
  • good conduction of electrical current,
  • Compensation of linear expansions and vibrations of the entire system so that these do not shift the contact point and thus lead to damage to the contact point through fretting corrosion,
  • Minimization of forces that are permanently applied to solder joints (which can be made using THT or SMD technology) of the contact partner of the flat contact and that can stress and damage these solder joints over time,
  • Compensation of tolerances of the overall system so that they do not generate any force on the contact partner of the flat contact and its soldering points,
  • Positioning of the flat contact to the contact partner during the mating process,
  • easy installation of the flat contact.

Die Montage des Flachkontakts erfolgt durch Einsetzen in eine Kontaktkammer, welche insbesondere Teil eines Steckverbindergehäuses oder eines Gerätegehäuses sein kann. Die Endabschnitte der Federarme, die als Rasthaken ausgebildet sind, verrasten mit Rastausnehmungen, die in die Kontaktkammer eingeformt sind. Vorzugsweise steht der Flachkontakt nur über diese Rasthaken mit der Kontaktkammer in mechanischer Verbindung.The flat contact is mounted by inserting it into a contact chamber, which can in particular be part of a connector housing or a device housing. The end sections of the spring arms, which are designed as locking hooks, lock into locking recesses that are formed in the contact chamber. The flat contact is preferably only mechanically connected to the contact chamber via these locking hooks.

Der Flachkontakt befindet sich in montierten Zustand in einer Mittelstellung innerhalb der Kontaktkammer. Dies ermöglicht eine Bewegung und dadurch eine Positionierung des Flachkontakts relativ zur Kontaktkammer, sowie auch zum Kontaktpartner des Flachkontakts. Der Kontaktpartner des Flachkontakts kann insbesondere als ein Gabelkontakt ausgeführt sein. Toleranzen und Kräfte baut der Flachkontakt durch die Torsion und Verbiegung der Federarme innerhalb der Kontaktkammer ab.When assembled, the flat contact is in a central position within the contact chamber. This allows movement and therefore positioning of the flat contact relative to the contact chamber, as well as to the contact partner of the flat contact. The contact partner of the flat contact can in particular be designed as a fork contact. The flat contact reduces tolerances and forces through the torsion and bending of the spring arms within the contact chamber.

Der Flachkontakt ist somit nach der Montage in der Kontaktkammer beweglich gelagert. Falls eine Vibrationsquelle auf die Kontaktkammer einwirkt bewirken die mechanische Trägheit des Flachkontakts und die Federwirkung der Federarme eine nur gedämpfte Übertragung von Vibrationen von der Kontaktkammer auf das Messerkontaktelement des Flachkontakts. Damit kommt es auch unter mechanischen Vibrationsbelastungen zu keinen bedeutsamen Verschiebungen der Kontaktelemente gegeneinander, die eine Schädigung der Kontaktstelle bewirken könnten.After assembly, the flat contact is thus movably mounted in the contact chamber. If a source of vibration acts on the contact chamber, the mechanical inertia of the flat contact and the spring action of the spring arms result in only a dampened transmission of vibrations from the contact chamber to the blade contact element of the flat contact. This means that even under mechanical vibration loads, there is no significant displacement of the contact elements against each other that could cause damage to the contact point.

Dabei ist es vorteilhaft, wenn die Rastausnehmungen entlang der Längsrichtung der Kontaktkammer größer ausgebildet sind als die Rasthaken und damit Freiräume ausbilden, in der die Rasthaken in der Längsrichtung der Kontaktkammer beweglich angeordnet sind.It is advantageous if the locking recesses along the longitudinal direction of the contact chamber are larger than the locking hooks and thus form free spaces in which the locking hooks are movably arranged in the longitudinal direction of the contact chamber.

Vorteilhaft ist, dass der Messerkontaktabschnitt sich in einer Sollstellung befindet und durch die Einführschrägen des Gegenkontaktes unter geringer Gegenkraft ausgelenkt werden kann. Spannungen in den Lötstellen werden durch Toleranzen des Aufbaus, Flachkontakt und Gegenkontakt verursacht.It is advantageous that the blade contact section is in a desired position and can be deflected by the insertion bevels of the counter contact with a small counterforce. Stresses in the soldering points are caused by tolerances in the structure, flat contact and counter contact.

Nachfolgend soll ein erfindungsgemäß ausgebildeter Flachkontakt und eine Flachsteckverbinderanordnung mit einem derartigen Flachkontakt anhand der Zeichnung dargestellt und näher erläutert werden. Es zeigen die

Die Figur 1 zeigt eine Draufsicht auf einen erfindungsgemäß ausgebildeten Flachkontakt 10. Die Figur 2 verdeutlicht durch eine Seitenansicht, dass der Flachkontakt 10 im Ganzen einen ebenen Aufbau aufweist. Daher kann er in einem Arbeitsgang einfach einem ebenen Blechstück ausgestanzt werden, ohne dass etwa Biegevorgänge als weitere Arbeitsschritte erforderlich wären. Der Flachkontakt 10 kann dadurch äußerst kostengünstig hergestellt werden.The Figure 1 shows a plan view of a flat contact 10 designed according to the invention. The Figure 2 shows through a side view that the flat contact 10 has a flat structure as a whole. It can therefore be simply punched out of a flat piece of sheet metal in one operation, without any bending processes being required as additional work steps. The flat contact 10 can therefore be manufactured extremely cost-effectively.

Der einstückige Flachkontakt 10 weist einen zentralen flachen Metallstreifen 16 auf, der an einem Endabschnitt einen Messerkontakt 11 und an seinem anderen Endabschnitt einen Leitungskontaktierungsabschnitt 17 ausbildet.The one-piece flat contact 10 has a central flat metal strip 16 which forms a blade contact 11 at one end portion and a line contacting portion 17 at its other end portion.

Der Leitungskontaktierungsabschnitt 17 kann auf unterschiedliche Weise ausgeführt sein und insbesondere einen Crimp-, Löt-, Schweiß- oder einen weiteren Messerkontaktabschnitt ausbilden.The line contacting section 17 can be designed in different ways and in particular form a crimping, soldering, welding or another blade contact section.

An die beiden langen Schmalseiten 19 des Metallstreifens 16 ist jeweils ein Federarm 12, 13 angeformt. Die Anformungsstellen 46, 47 sind dabei, bezogen auf die Längsrichtung des Metallstreifens 16, vorzugsweise auf gleicher Höhe angeordnet. Vorzugsweise sind die beiden Federarme 12, 13 spiegelsymmetrisch zur Längsachse des Metallstreifens 16 ausgebildet und angeordnet.A spring arm 12, 13 is formed on each of the two long narrow sides 19 of the metal strip 16. The forming points 46, 47 are preferably arranged at the same height in relation to the longitudinal direction of the metal strip 16. The two spring arms 12, 13 are preferably designed and arranged mirror-symmetrically to the longitudinal axis of the metal strip 16.

Die Endabschnitte der Federarme 12, 13 weisen jeweils einen einstückig angeformten Rasthaken 14, 15 auf. Zwischen den Anformungsstellen 46, 47 und den Rasthaken 14, 15 ist jeder Federarm 12, 13 mehrfach abgerundet, so dass sich seine Erstreckungsrichtung mehrfach ändert. Dabei bildet jeder Federarm 12, 13 aufeinanderfolgend mindestens zwei kehrenartige Kurven 40, 41, 42, 43 aus.The end sections of the spring arms 12, 13 each have an integrally formed locking hook 14, 15. Between the forming points 46, 47 and the locking hooks 14, 15, each spring arm 12, 13 is rounded several times, so that its direction of extension changes several times. Each spring arm 12, 13 forms at least two successive bends 40, 41, 42, 43.

Durch diese mehrfachen kehrenartigen Kurven 40, 41, 42, 43 erstrecken sich die Federarme 12, 13 insgesamt hauptsächlich parallel zur Längsachse des Metallstreifens 16 des Kontaktelements 1.Due to these multiple, sweeping curves 40, 41, 42, 43, the spring arms 12, 13 extend mainly parallel to the longitudinal axis of the metal strip 16 of the contact element 1.

Zur Herstellung eines Flachsteckverbinders 1 wird der Flachkontakt 10 in eine Kontaktkammer 30 eingesetzt, wodurch der in der Figur 3, und deutlicher in der Schnittansicht der Figur 4 dargestellte Montagezustand hergestellt ist. Bei diesem Montageschritt kann der Flachkontakt 10 bereits eine elektrisch und mechanisch angebundene Anschlussleitung 50 aufweisen.To produce a flat plug connector 1, the flat contact 10 is inserted into a contact chamber 30, whereby the Figure 3 , and more clearly in the sectional view of the Figure 4 shown assembly state is established. In this assembly step, the flat contact 10 can already have an electrically and mechanically connected connecting line 50.

Die Kontaktkammer 30 dient zur Halterung des Flachkontakts 10 und kann insbesondere ein Teil eines hier nicht näher dargestellten Steckverbindergehäuses oder eines Gerätegehäuses sein.The contact chamber 30 serves to hold the flat contact 10 and can in particular be a part of a connector housing (not shown in detail here) or a device housing.

Die Figur 4 verdeutlicht, dass die Rasthaken 14, 15 der Federarme 12, 13 in Rastausnehmungen 34, 35 der Kontaktkammer 30 eingesetzt sind. Die Kontaktkammer 30 ist so ausgeführt, dass der zentrale Metallstreifen 16 des Flachkontakts 10 die Innenwände der Kontaktkammer 30 nicht berührt und somit gegen die Kraft der Federarme 12, 13 in mehrere Richtungen verschieb- und verkippbar ist. Hierdurch werden auf die Kontaktkammer 30 einwirkende Einwirkungen von den Federarmen 12, 13 abgeschwächt, so dass etwas äußere Vibrationen sich nicht mehr oder zumindest nur deutlich vermindert auf den Messerkontaktabschnitt 11 des Flachkontakts 10 übertragen.The Figure 4 shows that the locking hooks 14, 15 of the spring arms 12, 13 are inserted into locking recesses 34, 35 of the contact chamber 30. The contact chamber 30 is designed in such a way that the central metal strip 16 of the flat contact 10 does not touch the inner walls of the contact chamber 30 and can therefore be moved and tilted in several directions against the force of the spring arms 12, 13. As a result, effects on the contact chamber 30 from the spring arms 12, 13 are weakened so that some external vibrations are no longer transmitted to the blade contact section 11 of the flat contact 10 or at least are transmitted only to a significantly reduced extent.

Die Rasthaken 14, 15 der Federarme 12, 13 sind in Rastausnehmungen 34, 35 eingesetzt, welche in der Längsrichtung der Federarme 12, 13 etwas größer ausgebildet sind als die Rasthaken 14, 15, so dass in den Rastausnehmungen 34, 35 nach dem Einsetzen der Rasthaken 14, 15 noch jeweils ein Freiraum 36, 37 verbleibt, in dem sich die Rasthaken entlang der durch ein Koordinatendreibein verdeutlichten z-Richtung bewegen können. Dieses ist vorteilhaft, da die Federarme 12, 13 in der z-Richtung starrer ausgebildet sind als in der x- und der y-Richtung. In der x- und der y-Richtung können daher die Federarme 12, 13 Bewegungen des Metallstreifens 16 relativ zur Kontaktkammer 30 recht gut federnd ausgleichen.The locking hooks 14, 15 of the spring arms 12, 13 are inserted into locking recesses 34, 35, which are slightly larger in the longitudinal direction of the spring arms 12, 13 than the locking hooks 14, 15, so that in the locking recesses 34, 35 after the locking hooks 14, 15 have been inserted, a free space 36, 37 remains in each case in which the locking hooks can move along the z-direction, which is illustrated by a coordinate tripod. This is advantageous because the spring arms 12, 13 are more rigid in the z-direction than in the x- and y-directions. In the x- and y-directions, the spring arms 12, 13 can therefore compensate for movements of the metal strip 16 relative to the contact chamber 30 quite well in a springy manner.

In der Flachsteckverbinderanordnung 100 ist der Flachsteckverbinder 1 mit einem Gegensteckverbinder 20 verbunden, der in den Figuren 5 und 6 als ein Gabelfederkontakt dargestellt ist. Der Messerkontaktabschnitt 11 des Flachkontakts 10 wird hier von zwei Kontaktfederpaaren 22 des Gabelfederkontakts 20 klemmend gehalten.In the flat connector arrangement 100, the flat connector 1 is connected to a mating connector 20, which is inserted into the Figures 5 and 6 as a fork spring contact. The blade contact section 11 of the flat contact 10 is held clamped here by two contact spring pairs 22 of the fork spring contact 20.

Durch die über die Federarme 12, 13 bewirkte Entkopplung übertragen sich auf die Kontaktkammer 30 einwirkende Belastungen nicht oder zumindest in deutlich vermindertem Maße auf die Verbindung zwischen dem Flachkontakt 10 und dem Gabelkontakt 20 und vermindern so die Gefahr des Auftretens von Reibkorrosion an dem Messerkontaktabschnitt 11, den Kontaktfederpaaren 22 sowie an den Lötstiften 24 des Gabelkontaktes 20.Due to the decoupling effected by the spring arms 12, 13, loads acting on the contact chamber 30 are not transferred, or at least are transferred to a significantly reduced extent, to the connection between the flat contact 10 and the fork contact 20, thus reducing the risk of fretting corrosion occurring on the blade contact section 11, the contact spring pairs 22 and on the solder pins 24 of the fork contact 20.
