Die Erfindung betrifft eine Kontaktbuchse für einen Flachstecker mit einem im Querschnitt rechteckigen Steckerstift, der eine vorbestimmte Breite und Dicke aufweist, mit einem Kontaktelement, das eine Längsachse bildet, das zwei federnde Kontaktzungen aufweist, die sich entlang der Längsachse einander annähern und jeweils eine Kontaktzone aufweisen und die dazu bestimmt sind, den Steckerstift zwischen sich eingespannt zu kontaktieren, wobei die Kontaktzonen einander gegenüberliegen, einem Stützelement, das rohrförmig rechteckig gestaltet ist und durch vier Wände begrenzt ist, die das Kontaktelement umschließen, in dem die federnden Kontaktzungen aufgenommen sind, wobei zwei gegenüberliegende Wände die Kontaktzungen überdecken, das mit dem Kontaktelement verbunden ist, das an den zwei gegenüberliegenden Wänden, die nicht die Kontaktzungen überdecken, jeweils eine Sperrzunge aufweist, wobei die Sperrzungen zwischen die federnden Kontaktzungen greifen und deren Kontaktzonen, solange der Flachstecker nicht eingesteckt ist, vorgespannt und kontaktfrei auf einem Abstand zueinander halten, der geringer ist als die Dicke des einzuführenden Steckerstiftes und Mitteln zum elektrisch leitenden Verbinden eines Leiters.The invention relates to a contact socket for a tab having a rectangular cross-sectional pin having a predetermined width and thickness, with a contact element which forms a longitudinal axis having two resilient contact tongues which approach each other along the longitudinal axis and each having a contact zone and which are intended to contact the pin between them clamped, wherein the contact zones face each other, a support member which is tubular in shape rectangular and is bounded by four walls which enclose the contact element, in which the resilient contact tongues are accommodated, two opposite walls cover the contact tongues, which is connected to the contact element, which has in each case a locking tongue on the two opposite walls which do not overlap the contact tongues, wherein the locking tongues engage between the resilient contact tongues and their contact zones as long as the tab is not inserted, biased and non-contact at a distance to each other, which is less than the thickness of the inserted plug pin and means for electrically conductive connection of a conductor.

Die DE 297 19 153 U1 beschreibt eine Kontaktbuchse für einen Flachstecker mit einem im Querschnitt rechteckigen Steckerstift mit vorbestimmter Breite und Dicke. Die Kontaktbuchse umfasst ein Kontaktelement, welches eine Längsachse bildet. Das Kontaktelement weist zwei federnde Kontaktzungen auf, die sich entlang der Längsachse einander annähern und jeweils eine Kontaktzone aufweisen, die dazu bestimmt sind, den Steckerstift zwischen sich eingespannt zu kontaktieren. Die Kontaktzonen liegen einander gegenüber. Die Kontaktbuchse umfasst ferner ein Stützelement, das rohrförmig gestaltet und durch Wände begrenzt ist, die das Kontaktelement umschließen. In dem Stützelement sind die federnden Kontaktzungen aufgenommen. Die Kontaktzungen werden durch Stützzungen beaufschlagt. Das Stützelement weist an zwei gegenüberliegenden Wänden jeweils eine Sperrzunge auf, die zwischen die federnden Kontaktzungen greifen und deren Kontaktzonen, solange der Flachstecker nicht eingesteckt ist, vorgespannt auf einem Abstand zueinander halten, der geringer ist als die Dicke des einzuführenden Steckerstiftes. Die Sperrzungen sollen darüber hinaus den Flachstecker beim Einführen führen. Sie sind nach innen zum Kontaktpunktbereich gebogen und sind mit den den zugehörigen Wänden der Einführöffnung der Kontaktbuchsen nahen Enden verbunden.The DE 297 19 153 U1 describes a contact socket for a tab with a rectangular cross-section pin with a predetermined width and thickness. The contact socket comprises a contact element which forms a longitudinal axis. The contact element has two resilient contact tongues which approach each other along the longitudinal axis and each have a contact zone intended for this purpose are to contact the connector pin clamped between them. The contact zones are opposite each other. The contact socket further comprises a support element which is tubular and bounded by walls which surround the contact element. In the support member, the resilient contact tongues are accommodated. The contact tongues are acted upon by supporting tongues. The support member has on two opposite walls in each case a locking tongue which engage between the resilient contact tongues and whose contact zones, as long as the tab is not inserted, biased hold at a distance from each other, which is less than the thickness of the inserted plug pin. The locking tongues should also lead the tab during insertion. They are bent inwardly to the contact point area and are connected to the associated walls of the insertion of the contact terminals near ends.

In der EP 0 352 871 B1 ist eine Kontaktbuchse für einen Flachstecker mit einem im Querschnitt rechteckigen Steckerstift, in der Beschreibung Kastenfeder genannt, erläutert. Die Kontaktbuchse umfasst ein Kontaktelement, das einen Basisabschnitt aufweist, von dem zwei federnde Kontaktzungen ausgehen, die sich vom ersten Ende weg entlang der Längsachse erstrecken und einander annähern. Die Kontaktzungen bilden an ihren freien Enden Kontaktzonen. Die Kontaktzungen streben, ausgehend von den Kontaktzonen, auseinander. Das Kontaktelement und insbesondere die federnden Kontaktzungen werden von einer sogenannten Überfeder (Stützelement) umschlossen, wobei die Überfeder Überfederarme besitzt, die auf den Kontaktzungen aufliegen und diese zusätzlich stützen.In the EP 0 352 871 B1 is a contact socket for a tab with a rectangular cross-section pin pin, called in the description box spring explained. The contact socket comprises a contact element having a base portion from which emanate two resilient contact tongues extending along the longitudinal axis from the first end and approaching each other. The contact tongues form contact zones at their free ends. The tongues strive, starting from the contact zones, apart. The contact element and in particular the resilient contact tongues are enclosed by a so-called over-spring (support element), wherein the over-spring has over-spring arms which rest on the contact tongues and additionally support them.

Bei den zwei rechtwinklig zu den Kontaktfedern versetzten Wänden der Überfeder sind zwei Einbuchtungen vorhanden, welche die Kontaktzungen auf Abstand vorgespannt halten, solange kein Steckerstift eingeführt ist. Die eingebuchteten Bereiche sind dadurch erzeugt, dass zwei parallele Schnitte in der Wandung der Überfeder vorhanden sind, so dass sich ein mit der Wandung der Kastenfeder verbundener Streifen ergibt, der in Richtung auf die Kontaktzungen zu verformt ist.In the two offset perpendicular to the contact springs walls of the over-spring two indentations are present, which keep the contact tongues biased at a distance, as long as no pin is inserted. The indented areas are created by having two parallel cuts in the wall of the over-spring so that there is a strip connected to the wall of the box spring that is deformed towards the contact tongues.

Von Nachteil bei beiden Ausführungen ist, dass durch die eingebuchteten Bereiche bzw. Sperrzungen zwar ermöglich ist, die Kontaktzungen auf Vorspannung zu halten, so dass bei eingestecktem Steckerstift ein hoher Kontaktdruck erzielt wird, dass jedoch in seitlicher Richtung die Möglichkeit gegeben ist, dass der Steckerstift vibriert, so dass ein entsprechender Verschleiß auftritt und aufgrund der Vibrationen im Betrieb auch Geräusche entstehen können.A disadvantage of both embodiments is that although it is possible by the indented areas or locking tongues to keep the contact tongues on bias, so that when the plug pin plugged in a high contact pressure is achieved, but that there is the possibility in the lateral direction that the plug pin vibrates, so that a corresponding wear occurs and noise may occur due to the vibrations during operation.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Kontaktbuchse bereitzustellen, bei der ebenfalls gewährleistet ist, dass die Kontaktzungen mit einer hohen Vorspannkraft im Betrieb einen Steckerstift zwischen sich halten, so dass eine günstige elektrische Verbindung hergestellt ist, die jedoch darüber hinaus geeignet ist, Schwingungen, die im Betrieb an den Steckerstiften auftreten, zu dämpfen.The invention is therefore based on the object to provide a contact socket, which also ensures that the contact tongues hold a plug pin with a high biasing force in operation between them, so that a favorable electrical connection is made, which is also suitable, however, vibrations , which occur in operation on the connector pins to attenuate.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Sperrzungen federnd ausgebildet sind,
dass der freie Abstand zwischen den beiden Sperrzungen vor dem Einführen eines Steckerstiftes geringer als die Breite des Steckerstiftes ist und
dass die Sperrzungen den Steckerstift im eingeführten Zustand entlang der Längsachse in einem Kontaktbereich berühren, der weiter von einem ersten Ende des Stützelementes versetzt ist als die Kontaktzonen der Kontaktzungen.This object is achieved in that the locking tongues are resilient,
that the free distance between the two locking tongues before insertion of a connector pin is less than the width of the connector pin and
in that the locking tongues contact the plug pin in the inserted state along the longitudinal axis in a contact region which is further offset from a first end of the support element than the contact zones of the contact tongues.

Von Vorteil bei dieser Ausbildung ist, dass der Steckerstift, der in der Kontaktbuchse aufgenommen wird, sowohl über die Kontaktzungen als auch über die Sperrzungen federnd beaufschlagt ist, so dass eine sichere Halterung gegeben ist.An advantage of this design is that the pin, which is accommodated in the contact socket, is resiliently acted upon both via the contact tongues and on the locking tongues, so that a secure support is provided.

Hierdurch wird erreicht, dass der Steckerstift schon zu einem erheblichen Maße eingeführt werden kann, so dass das Vorzentrieren und Einführen nicht unter der vollen Vorspannungskraft erfolgen muss. Darüber hinaus werden Schwingungen wirksam gedämpft, die quer zur Wirkungsrichtung der Kontaktzungen auftreten. Solche Schwingungen können nämlich Reibkorrosion bzw. Verschleiß in den Kontaktzonen herbeiführen, wodurch die Übergangswiderstände erheblich verschlechtert werden. Da die Sperrzungen den Steckerstift beim Einführen erst später als dieser die Kontaktzonen der Kontaktzungen berühren, ist zunächst beim Einführen nur die Vorspannung der Kontaktzungen zu überwinden und erst später der Kontaktdruck der Sperrzungen. Die Sperrzungen sind mit ihrem der Einführöffnung bzw. des Stützelementes nahen Ende mit den beiden Wänden verbunden, die sich einander gegenüberliegen und die nicht dazu genutzt werden, die Kontaktzungen vorgespannt abzustützen. Die freien Enden der Sperrzungen weisen also von der Einführöffnung bzw. dem ersten Ende des Stützelementes weg. Beim Stand der Technik nach der EP 0 352 871 E1 und der DE 297 19 153 U1 üben die Einbuchtungen bzw. Sperrzungen keine Kräfte auf die seitlichen Flächen des Steckerstiftes ausüben, da diese relativ steif sind, d.h. keinen Federweg zur Verfügung stellen. Im übrigen erfolgt die Abstützung der Kontaktzungen im Bereich deren Kontaktzonen, so dass die Einbuchtungen den Steckerstift nur seitlich führen dürfen, um die Kräfte, die beim Einführen des Steckerstiftes zu überwinden sind, noch vertretbar gering zu halten. Ansonsten bestünde die Gefahr, dass beim Einführen des Steckerstiftes ein Verbiegen desselben erfolgen würde.This ensures that the pin can already be introduced to a considerable extent, so that the pre-centering and insertion must not be made under the full biasing force. In addition, vibrations are effectively damped, which occur transversely to the direction of action of the contact tongues. Namely, such vibrations can cause fretting corrosion or wear in the contact zones, whereby the contact resistance is significantly deteriorated. Since the locking tabs touch the plug pin during insertion later than this, the contact zones of the contact tongues, initially only the bias of the contact tongues to overcome during insertion and only later the contact pressure of the locking tabs. The locking tongues are with their the insertion or the support element near end connected to the two walls, which are opposite to each other and are not used to support the contact tongues biased. The free ends of the locking tongues thus point away from the insertion opening or the first end of the support element. In the prior art after the EP 0 352 871 E1 and the DE 297 19 153 U1 practice the indentations or locking tongues exert no forces on the lateral surfaces of the pin, since they are relatively stiff, ie provide no spring travel available. Moreover, the support of the contact tongues in the region of their contact zones, so that the indentations may only lead the connector pin laterally to keep the forces that are to be overcome during insertion of the connector pin, still reasonable to keep. Otherwise, there would be a risk that the insertion of the pin would be the same bending.

In Ausgestaltung der Erfindung ist für eine erste Ausführungsform vorgesehen, dass

  • ein Kontaktelement einen hohlen rechteckigen Basisabschnitt mit einem ersten Ende und einem zweiten Ende und vier Seitenwänden, die sich paarweise gegenüberliegen, aufweist,
  • bei dem von dem ersten Ende des Basisabschnitts von zwei gegenüberliegenden Seitenwänden jeweils eine federnde Kontaktzunge entlang der Längsachse vorsteht, die sich vom ersten Ende weg einander annähern und gegenüberliegend jeweils eine Kontaktzone bilden.
In an embodiment of the invention, it is provided for a first embodiment that
  • a contact element comprises a hollow rectangular base portion having a first end and a second end and four side walls facing each other in pairs,
  • wherein each of the first end of the base portion of two opposing side walls protrudes a resilient contact tongue along the longitudinal axis, which approach each other away from the first end and opposite to each form a contact zone.

Bei dieser Ausbildung sind die federnden Kontaktzungen dem Kontaktelement zugeordnet. Dieses ist durch die hohle rechteckige Ausbildung des Basisabschnittes entsprechend starr gestaltet, wobei zusätzlich die Stützung über das das Kontaktelement umschließende Stützelement erfolgt. Es ist aufgrund dieser Gestaltung auch möglich, das Kontaktelement und das Stützelement aus unterschiedlichen Materialien zu gestalten. Von Vorteil ist beispielsweise, wenn das Stützelement aus einem nicht rostenden Stahl hergestellt wird und dazu beispielsweise aus einem Blech geformt wird, so dass eine Kastenform entsteht, wobei die Sperrzungen auch bewirken, dass die vorbestimmte Position eingehalten ist und keine Drehverlagerung erfolgen kann. Das Kontaktelement kann aus einem Werkstoff hergestellt werden, der eine gute elektrische Leitfähigkeit aufweist.In this embodiment, the resilient contact tongues are associated with the contact element. This is designed by the hollow rectangular shape of the base portion according to rigid, in addition, the support via the contact element enclosing the support element takes place. It is also possible because of this design, to make the contact element and the support element made of different materials. It is advantageous, for example, if the support element is made of a stainless steel and is formed, for example, from a sheet, so that a box shape is formed, wherein the locking tongues also cause the predetermined position is met and no rotational displacement can take place. The contact element can be made of a material having a good electrical conductivity.

Ein solcher Aufbau ist insbesondere von Bedeutung, da es sich um extrem kleine Anschlussbuchsen handelt, die zum Beispiel für Steckerstifte gedacht sind, bei denen der rechteckige Querschnitt eine Breite im Bereich von 1 mm und eine Dicke im Bereich von 0,6 mm aufweist.Such a construction is particularly important, since they are extremely small sockets intended, for example, for connector pins in which the rectangular cross-section has a width in the range of 1 mm and a thickness in the range of 0.6 mm.

In Ausgestaltung der Erfindung ist vorgesehen, dass die Mittel zum elektrisch leitenden Verbinden eines Leiters durch einstückig mit dem zweiten Ende des Basisabschnitts des Kontaktelements ausgebildete Crimplaschen dargestellt sind.In an embodiment of the invention it is provided that the means for electrically conductive connection of a conductor are formed by integrally formed with the second end of the base portion of the contact element Crimplaschen.

Zusätzlich sind für einen isolierten Leiter noch Crimplaschen vorgesehen, die zum Quetschverbinden mit der Isolierung dienen.In addition, Crimplaschen are still provided for an insulated conductor, which serve for crimping with the insulation.

Eine weitere Ausführungsform sieht vor, dass das Stützelement die Verbindung zum Leiter bewirkt, während das Kontaktelement lediglich zwei miteinander verbundene Kontaktzungen aufweist, die in dem Stützelement aufgenommen sind. In diesem Fall ist vorgesehen, dass die Mittel zum elektrisch leitenden Verbinden eines Leiters durch einstückig mit dem Stützelement ausgebildete Crimplaschen dargestellt sind.A further embodiment provides that the support element causes the connection to the conductor, while the contact element has only two mutually connected contact tongues, which are accommodated in the support element. In this case, it is provided that the means for electrically conductive connection of a conductor are formed by crimps formed integrally with the support element.

Zur Erleichterung des Einführens bei beiden Ausführungsformen ist vorgesehen, dass die Kontaktzungen anschließend an die Kontaktzone in Richtung zur Einführöffnung der Kontaktbuchse wieder auseinanderstreben.In order to facilitate the insertion in both embodiments, it is provided that the contact tongues subsequently diverge again from the contact zone in the direction of the insertion opening of the contact socket.
