Description

Stand der TechnikState of the art

Die Erfindung betrifft einen Kontaktierungsstecker zum Kontaktieren eines Kontaktträgers, insbesondere einer Leiterplatte, gemäß dem Oberbegriff des Anspruchs 1 sowie eine einen Kontaktierungsstecker umfassende Kontaktierungsverbindung gemäß Anspruch 11.The invention relates to a Kontaktierungsstecker for contacting a contact carrier, in particular a printed circuit board, according to the preamble of claim 1 and a Kontaktierungsstecker comprehensive Kontaktierungsverbindung according to claim 11.

Ein Kontaktierungsstecker gemäß dem Oberbegriff des Anspruches 1 ist aus dem Dokument US 3,594,699 bekannt.A Kontaktierungsstecker according to the preamble of claim 1 is from the document US 3,594,699 known.

Eine bekannte Kontaktierungsverbindung, umfassend einen Kontaktierungsstecker, sowie eine Kontaktierungssteckeraufnahme ist in der DE 10 2005 063 239 A1 beschrieben. Die bekannte Kontaktierungsverbindung zeichnet sich dadurch aus, dass die von Kontaktelementen auf eine Leiterplatte aufgebrachten Kontaktkräfte unabhängig sind von Klemmkräften, mit denen die die Kontaktelemente tragenden, als Kontakthalter ausgebildeten Klemmklauen an der Leiterplatte anliegen. Die bekannte Kontaktierungsverbindung hat sich bewährt. Problematisch erscheint jedoch, dass es im nicht kontaktierenden, d.h. nicht eingesteckten, Zustand des Kontaktierungssteckers zu einer Beschädigung der Kontaktelemente kommen kann, da die Kontaktelemente aufgrund der federnden Wirkung der Federmittel gegen die jeweils gegenüberliegende Klemmklaue bzw. gegen die gegenüberliegende Kontaktelemente gepresst werden.A known Kontaktierungsverbindung comprising a Kontaktierungsstecker, and a Kontaktierungssteckeraufnahme is in the DE 10 2005 063 239 A1 described. The known Kontaktierungsverbindung is characterized by the fact that the applied contact elements on a printed circuit board contact forces are independent of clamping forces with which the contact elements carrying, designed as a contact holder clamping jaws abut the circuit board. The known Kontaktierungsverbindung has been proven. The problem, however, appears that it may come in non-contacting, ie not plugged, state of Kontaktierungssteckers damage to the contact elements, since the contact elements are pressed due to the resilient action of the spring means against the respective opposite clamping jaw or against the opposite contact elements.

Aus der EP 0 083 862 A2 ist bereits ein Kontaktierungsstecker zum Kontaktieren eines Kontaktträgers, insbesondere einer Leiterplatte bekannt, der zwei quer zu einer Einsteckrichtung relativ zueinander verschwenkbaren Klemmklauen besitzt. Von den Klemmklauen ist zumindest eine als zumindest ein federndes Kontaktelement tragender Kontakthalter ausgebildet, der zum Aufliegen auf dem Kontaktträger mit einer Kontaktkraft ausgebildet ist, wobei die Klemmklauen mindestens jeweils eine Anschlagfläche aufweisen, die im nicht kontaktierenden Zustand des Kontaktierungssteckers aneinander anliegen und damit eine plastische Verformung des Kontaktelementes verhindern.From the EP 0 083 862 A2 is already a Kontaktierungsstecker for contacting a contact carrier, in particular a printed circuit board known, which has two transversely to a plug-in direction relative to each other pivotable clamping jaws. Of the clamping claws, at least one contact holder carrying at least one resilient contact element is formed, which is designed to rest on the contact carrier with a contact force, wherein the clamping claws at least each have a stop surface which abut each other in the non-contacting state of Kontaktierungssteckers and thus a plastic deformation prevent the contact element.

Offenbarung der ErfindungDisclosure of the invention Technische AufgabeTechnical task

Der Erfindung liegt die Aufgabe zugrunde, den Kontaktstecker der Direkt-Kontaktierungsverbindung dahingehend zu verbessern, dass eine Beschädigung der Kontaktelemente im nicht eingesteckten, nicht kontaktierenden Zustand des Kontaktierungssteckers vermieden wird. Ferner besteht die Aufgabe darin, eine Kontaktierungsverbindung, umfassend einen entsprechend verbesserten Kontaktierungsstecker, vorzuschlagen.The object of the invention is to improve the contact plug of the direct contacting connection such that damage to the contact elements in the non-inserted, non-contacting state of the contacting plug is avoided. Furthermore, the object is to propose a contacting connection comprising a correspondingly improved contacting plug.

Technische LösungTechnical solution

Diese Aufgabe wird hinsichtlich des Kontaktierungssteckers mit den Merkmalen des Anspruchs 1 und hinsichtlich der Kontaktierungsverbindung mit den Merkmalen des Anspruchs 11 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. In den Rahmen der Erfindung fallen sämtliche Kombinationen aus zumindest zwei von in der Beschreibung, den Ansprüchen und/oder den Figuren offenbarten Merkmalen.This object is achieved in terms of Kontaktierungssteckers with the features of claim 1 and in terms of Kontaktierungsverbindung with the features of claim 11. Advantageous developments of the invention are specified in the subclaims. All combinations of at least two features disclosed in the description, the claims and / or the figures fall within the scope of the invention.

Der Erfindung liegt der Gedanke zugrunde, jeder Klemmklaue mindestens eine Anschlagfläche zuzuordnen und die Anschlagflächen derart anzuordnen, dass sich die Klemmklauen mittels der Anschlagfläche im nicht eingesteckten Zustand des Kontaktierungssteckers, also dann, wenn das von den Klemmklauen gebildete Klemmmaul nicht geöffnet ist, aneinander abstützen. Wesentlich ist, dass die Anschlagflächen derart angeordnet sind, dass die Klemmklauen im Bereich der Kontaktelemente auf einem Mindestabstand voneinander gehalten werden, sodass verhindert wird, dass auf die Kontaktelemente die (volle) Klemmkraft wirkt. Anders ausgedrückt wird durch das Vorsehen von Anschlagflächen und deren entsprechende Anordnung zumindest eine plastische Verformung der Kontaktelemente verhindert, wodurch die Gefahr einer Beschädigung der Kontaktelemente im nicht eingesteckten Zustand des Kontaktierungssteckers auf ein absolutes Minimum reduziert ist.The invention is based on the idea to assign each clamping claw at least one stop surface and the stop surfaces to be arranged such that the clamping claws by means of the stop surface in the non-inserted state of Kontaktierungssteckers, so then when the clamp jaw formed by the clamping jaw is not open, supported each other. It is essential that the abutment surfaces are arranged such that the clamping claws are held in the region of the contact elements at a minimum distance from each other, so that it is prevented that the contact elements the (full) clamping force acts. In other words, the provision of stop surfaces and their corresponding arrangement at least prevents plastic deformation of the contact elements, whereby the risk of damage to the contact elements in the non-inserted state of Kontaktierungssteckers is reduced to an absolute minimum.

In der Erfindung ist vorgesehen, dass die Anschlagflächen derart angeordnet sind, dass nicht nur eine plastische Verformung des mindestens einen Kontaktelementes im nicht montierten, d.h. nicht kontaktierenden Zustand des Kontaktierungssteckers verhindert wird, sondern jegliche Verformung, also auch eine elastische Verformung. Hierdurch wird die Gefahr einer Beschädigung des mindestens einen Kontaktelementes noch weiter reduziert. Anders ausgedrückt sind die Anschlagflächen gemäß der beschriebenen Weiterbildung der Erfindung derart relativ zueinander angeordnet, dass die mindestens eine das mindestens eine federnde, vorzugsweise metallische Kontaktelement die gegenüberliegende Klemmklaue und/oder ein gegenüberliegendes Kontaktelement nicht berührt, sodass das Kontaktelement aufgrund der auf die Klemmklauen wirkenden, von den Federmitteln verursachten Klemmkräften nicht deformiert wird.In the invention it is provided that the stop surfaces are arranged such that not only a plastic deformation of the at least one contact element in the unassembled, i. non-contacting state of Kontaktierungssteckers is prevented, but any deformation, including an elastic deformation. As a result, the risk of damage to the at least one contact element is further reduced. In other words, the abutment surfaces according to the described embodiment of the invention are arranged relative to one another such that the at least one at least one resilient, preferably metallic contact element does not touch the opposite clamping claw and / or an opposing contact element, so that the contact element acts on the clamping claws, Clamping forces caused by the spring means is not deformed.

Ganz besonders bevorzugt ist eine Ausführungsform des Kontaktierungssteckers, bei der beide Klemmklauen jeweils mindestens zwei, vorzugsweise ausschließlich zwei quer zu einer Einsteckrichtung (Montagerichtung) des Kontaktierungssteckers voneinander beabstandete Anschlagflächen aufweisen, wobei die Anschlagflächen der unterschiedlichen Klemmklauen jeweils paarweise zusammenwirkend angeordnet sind.Very particular preference is given to an embodiment of the contacting plug, in which both clamping claws each have at least two, preferably only two transverse to a plug-in direction (mounting direction) of Kontaktierungssteckers spaced stop surfaces, wherein the abutment surfaces of the different clamping jaws are arranged in pairs cooperating.

In Weiterbildung der Erfindung ist mit Vorteil vorgesehen, dass sich die Anschlagflächen nicht auf einem mittleren Bereich des Kontaktierungssteckers befinden, sondern randseitig, d.h. im Bereich der Längsseiten, vorzugsweise an den in Einsteckrichtung vorderen Ecken des Kontaktierungssteckers.In a further development of the invention is advantageously provided that the abutment surfaces are not located on a central region of the Kontaktierungssteckers, but at the edge, i. in the region of the longitudinal sides, preferably at the front in the insertion direction of the Kontaktierungssteckers.

Wie zuvor erläutert, sind die Anschlagflächen, d.h. ist die Abstandshalterfunktion auf den nicht montierten Zustand des Kontaktierungssteckers ausgelegt. Die Abstandhalterfunktion ist im eingesteckten, d.h. montierten, den Kontaktträger kontaktierenden Zustand nicht mehr erforderlich und auch nicht erwünscht. In sofern ist in Weiterbildung der Erfindung mit Vorteil vorgesehen, dass die einander zugeordneten Anschlagflächen im eingesteckten Zustand des Kontaktierungssteckers voneinander beabstandet sind.As previously explained, the abutment surfaces, i. the spacer function is designed for the unmounted state of the contacting plug. The spacer function is in the inserted, i. mounted, the contact carrier contacting state no longer necessary and not desirable. In so far, it is advantageously provided in a development of the invention that the mutually associated abutment surfaces are spaced apart in the inserted state of the contacting plug.

Besonders zweckmäßig ist es, wenn die Klemmklauen nicht wie im Stand der Technik einteilig, sondern als zwei voneinander separate Bauteile ausgebildet sind. Bevorzugt handelt es sich im Hinblick auf eine vereinfachte Fertigung und Montage dabei um Gleichteile, vorzugsweise um Kunststoffspritzgussteile, die über zwei quer zur Einsteckrichtung voneinander beabstandete, insbesondere als Rastelemente ausgebildete Drehgelenke gelenkig miteinander verbunden sind.It is particularly expedient if the clamping claws are not formed in one piece as in the prior art, but as two separate components. With regard to a simplified production and assembly, these are preferably identical parts, preferably plastic injection-molded parts, which are connected to one another in an articulated manner via two swivel joints spaced apart from one another, in particular as latching elements.

Ganz besonders bevorzugt ist es, wenn sich der Kontaktträger mit entsprechenden Anlageflächen im eingesteckten, d.h. kontaktierenden Zustand nicht benachbart zu mindestens einer Leiterbahn und/oder mindestens einem Land des Kontaktträgers, sondern unmittelbar auf der Leiterbahn bzw. dem Land des Kontaktträgers abstützt, wodurch Fertigungstoleranzen im Bezug auf die Dickenerstreckung der Leiterbahn bzw. des Lands erstmals ausgeglichen werden können.It is particularly preferred if the contact carrier with corresponding contact surfaces in the inserted, ie contacting state not adjacent to at least one conductor track and / or at least one country of the contact carrier, but directly on the conductor track or the Land of the contact carrier is supported, whereby manufacturing tolerances in relation to the thickness extension of the conductor or the country can be compensated for the first time.

Besonders bevorzugt ist eine Ausführungsform des Kontaktierungssteckers, bei der der Kontakthalter mindestens eine die Lage des Kontaktelementes zum Kontaktträger definierende Anlagefläche aufweist. Anders ausgedrückt sind die Klemmklauen bevorzugt mit jeweils einer Anlagefläche versehen, die, wenn die Klemmklauen in der Endmontageposition auf dem Kontaktträger aufliegen, eine definierte Relativposition der Kontaktelemente zu der Leiterplatte bzw. eine definierte Relativposition der Aufnahmegräben für die Kontaktelemente zu der Leiterplatte sicherstellen und damit für eine definierte Vorspannung der, vorzugsweise metallischen, federnden Kontaktelemente bewirken, beispielsweise in der Art, wie dies in der DE 10 2005 063 239 A1 gezeigt und beschrieben ist. Besonders bevorzugt ist es, wenn sich die Anlageflächen nicht benachbart zu den Leiterbahnen bzw. Lands auf dem Kontaktträger abstützen, sondern unmittelbar auf mindestens einer Leiterbahn oder einem Land, um Fertigungstoleranzen im Hinblick auf die Dickenerstreckung der Leiterbahnen bzw. Lands auszugleichen.Particularly preferred is an embodiment of the contacting plug, wherein the contact holder has at least one contact surface defining the position of the contact element to the contact carrier. In other words, the clamping claws are preferably each provided with a contact surface which, when the clamping claws rest on the contact carrier in the final assembly position, ensure a defined relative position of the contact elements to the printed circuit board or a defined relative position of the receiving trenches for the contact elements to the printed circuit board and thus cause a defined bias of, preferably metallic, resilient contact elements, for example in the manner as shown in the DE 10 2005 063 239 A1 shown and described. It is particularly preferred if the contact surfaces are not supported adjacent to the conductor tracks or land on the contact carrier, but directly on at least one conductor track or a country to compensate for manufacturing tolerances with respect to the thickness extension of the conductors or land.

In Weiterbildung der Erfindung ist mit Vorteil vorgesehen, den Kontaktierungsstecker im Hinblick auf die Größe der Klemmkraft, mit der die, vorzugsweise als Kontakthalter ausgebildeten, Klemmklauen an dem Kontaktträger, insbesondere einer Leiterplatte, anliegen, autark auszubilden. Anders ausgedrückt ist die die Klemmklauen beaufschlagende Klemmkraft des Kontaktierungssteckers in Weiterbildung der Erfindung zumindest näherungsweise, vorzugsweise vollständig unabhängig von einer Kontaktierungssteckeraufnahme. Dies wird bevorzugt dadurch erreicht, dass sich die Federmittel im Endmontagezustand einer mit dem Kontaktierungsstecker ausgestatteten Kontaktierungsverbindung, also bei in der Kontaktierungssteckeraufnahme aufgenommenem Kontaktierungsstecker, zum Erzeugen der Klemmkraft nicht mehr wie im Stand der Technik an der Kontaktierungssteckeraufnahme abstützen, sondern ausschließlich am Kontaktierungsstecker. Die Federmittel greifen also ausschließlich am Kontaktierungsstecker an, derart, dass die Klemmklauen, von denen zumindest eine als mindestens ein federndes Kontaktelement tragender Kontakthalter ausgebildet ist, bestrebt sind, sich aufeinander zu zu bewegen. Noch anders ausgedrückt wirken die sich zum Erzeugen der Klemmkraft ausschließlich an dem Kontaktierungsstecker, vorzugsweise ausschließlich an den Klemmklauen, abstützenden Federmittel einer beim Einsteckvorgang erzwungenen Öffnungsbewegung der Klemmklauen entgegen. Da die Klemmkraft gemäß der beschriebenen Weiterbildung nicht länger abhängig ist von einer Formänderung oder Relaxation der Kontaktierungssteckeraufnahme, wird ein Unterschreiten einer minimal erforderlichen Klemmkraft mit Vorteil vermieden. Darüber hinaus kann der Aufbau des Kontaktierungssteckers aufgrund der speziellen Ausbildung und Anordnung der Federmittel wesentlich vereinfacht werden. Ggf. kann sogar auf das Vorsehen einer Kontaktierungssteckeraufnahme vollständig verzichtet werden.In a further development of the invention is advantageously provided, the Kontaktierungsstecker with respect to the size of the clamping force with which the, preferably designed as a contact holder, clamping claws on the contact carrier, in particular a circuit board, abut, self-sufficient form. In other words, the clamping force acting on the clamping jaws of the contacting plug is at least approximately in the invention, preferably completely independent of a contacting plug receptacle. This is preferably achieved in that the spring means in the final assembly state equipped with the Kontaktierungsstecker Kontaktierungsverbindung, that is not supported in the Kontaktierungssteckeraufnahme Kontaktierungsstecker to generate the clamping force no longer as in the prior art on the Kontaktierungssteckeraufnahme, but exclusively on Kontaktierungsstecker. The spring means thus act exclusively on the contacting plug, such that the clamping claws, of which at least one contact holder carrying at least one resilient contact element, are endeavored to move toward one another. Stated another way, the spring means, which are supported exclusively for generating the clamping force exclusively on the contacting plug, preferably exclusively on the clamping claws, counteract an opening movement of the clamping claws forced during the insertion process. Since the clamping force according to the described embodiment is no longer dependent on a change in shape or relaxation of Kontaktierungssteckeraufnahme, falling below a minimum required clamping force is advantageously avoided. In addition, the structure of the Kontaktierungssteckers be significantly simplified due to the special design and arrangement of the spring means. Possibly. can even be completely dispensed with the provision of a Kontaktierungssteckeraufnahme.

Besonders bevorzugt ist es, wenn die Federmittel derart ausgebildet und angeordnet sind, dass die von den Federmitteln erzeugte Klemmkraft und die von dem mindestens einen federnden Kontaktelement erzeugte Kontaktkraft in einer gemeinsamen Wirkebene liegen.It is particularly preferred if the spring means are designed and arranged such that the clamping force generated by the spring means and the contact force generated by the at least one resilient contact element lie in a common plane of action.

In Weiterbildung der Erfindung ist mit Vorteil vorgesehen, dass der Kontaktierungsstecker zum Zusammenwirken mit mindestens einem, die Federmittel beim Einstecken des Kontaktierungssteckers spannenden, Gegeneinsteckelement ausgebildet ist. Dabei ist das Gegeneinsteckelement bevorzugt Bestandteil einer eingangs erwähnten Kontaktierungssteckeraufnahme und wird beim Einstecken des Kontaktierungssteckers in eine entsprechende Aufnahme (Aufnahmekanal) desselben eingeschoben und bewirkt beim Einschubvorgang ein Aufweiten der Klemmklauen, also ein relatives Verschwenken derselben zueinander, also ein Öffnen des von den Klemmklauen gebildeten Klemmmauls, was wiederum zu einer Spannung der Federmittel führt.In a further development of the invention is advantageously provided that the Kontaktierungsstecker is designed to cooperate with at least one, the spring means when inserting the Kontaktierungssteckers exciting, Gegeneinsteckelement. In this case, the Gegeneinsteckelement is preferably part of a Kontaktierungssteckeraufnahme mentioned and inserted during insertion of the Kontaktierungssteckers in a corresponding receptacle (receiving channel) and causes the insertion process widening of the clamping jaws, ie a relative pivoting thereof to each other, so opening the clamping jaw formed by the clamping jaws , which in turn leads to a tension of the spring means.

Die Erfindung führt auch auf eine Kontaktierungsverbindung, umfassend mindestens einen zuvor beschriebenen Kontaktierungsstecker, dem eine, vorzugsweise auf einem Kontaktträger festgelegte, Kontaktierungssteckeraufnahme zugeordnet ist. Bevorzugt handelt es sich bei der Kontaktierungsverbindung um eine elektrische Direkt-Steckverbindung zur Leiterplattenkontaktierung von Steuergeräten und/oder Komponenten, insbesondere für Türsteuergeräte und/oder Motorsteuergeräte in Kraftfahrzeugen.The invention also leads to a contacting connection comprising at least one contacting plug described above, to which a contacting plug receptacle, which is preferably fixed on a contact carrier, is assigned.

In den Figuren sind gleiche Elemente und Elemente mit der gleichen Funktion mit den gleichen Bezugszeichen gekennzeichnet.In the figures, like elements and elements having the same function are denoted by the same reference numerals.

In Fig. 1 ist in einer unvollständigen Darstellung ein mögliches Ausführungsbeispiel eines Kontaktierungssteckers 1 zum Kontaktieren eines, vorzugsweise als Leiterplatte ausgebildeten, nicht dargestellten Kontaktträgers gezeigt. Mittels des Kontaktierungssteckers 1 kann eine elektrisch leitende Verbindung zwischen einem nicht gezeigten Kabelbaum und dem Kontaktträger hergestellt werden. Der Kontaktierungsstecker 1 umfasst zwei identisch ausgebildete und spiegelbildlich angeordnete Klemmklauen 2, 3, die jeweils als Kontakthalter 4, 5 ausgebildet sind, wobei dieser Kontakthalter 4, 5 in dem gezeigten Ausführungsbeispiel eine Vielzahl von quer zu einer Einsteckrichtung E nebeneinander angeordneten, federnden Kontaktelementen 6 aus Metall trägt. Diese dienen zur unmittelbaren Kontaktierung des nicht gezeigten Kontaktträgers, genauer einer Leiterbahn oder einem Land. Auf das Vorsehen von Messerleisten wird hierbei bewusst verzichtet. Die Kontaktelemente 6 sind als metallische, durch Biegen hergestellte Federelemente ausgebildet, die mit einer im Wesentlichen senkrecht zur Flächenerstreckung des Kontaktträgers orientierten Kontaktkraft an diesem anliegen. Die Kontaktkraft, mit der die Kontaktelemente 6 an dem Kontaktträger anliegen, ist unabhängig von einer Klemmkraft, mit der sich die Klemmklauen 2, 3 im Wesentlichen in Normalrichtung an dem Kontaktträger abstützen.In Fig. 1 is an incomplete illustration of a possible embodiment of a Kontaktierungssteckers 1 for contacting a, preferably designed as a printed circuit board, not shown contact carrier shown. By means of the Kontaktierungssteckers 1, an electrically conductive connection between a harness, not shown, and the contact carrier can be made. The Kontaktierungsstecker 1 comprises two identically formed and mirror-image arranged clamping jaws 2, 3, which are each formed as a contact holder 4, 5, said contact holder 4, 5 in the embodiment shown a plurality of transversely to a plug E arranged side by side, resilient contact elements 6 from Metal carries. These are used for direct contacting of the contact carrier, not shown, more precisely, a conductor or a country. On the provision of male connectors is deliberately omitted. The contact elements 6 are formed as metallic, produced by bending spring elements which bear with a substantially perpendicular to the surface extension of the contact carrier oriented contact force thereon. The contact force with which the contact elements 6 bear against the contact carrier is independent of a clamping force with which the clamping claws 2, 3 are supported in the normal direction on the contact carrier.

Zum Erzeugen der Klemmkraft sind Federmittel 7 vorgesehen, die von zwei als Drahtfederelementen ausgebildeten Federelementen 8, 9 gebildet sind. Diese sind formschlüssig miteinander verbunden und als Gleichteile ausgebildet, um die Herstellungskosten zu minimieren und die Montage zu vereinfachen. Wie sich aus Fig. 2 ergibt, sind die als Drahtfederelemente ausgebildeten Federelemente 8, 9 ineinander eingehängt und bilden somit die umfangsgeschlossenen Federmittel 7. Anders ausgedrückt, ergeben die Federmittel 8, 9 ein Ringfederelement, das die Klemmklauen 2, 3 in Richtung aufeinander zu federkraftbeaufschlagt. Anstelle der Herstellung einer formschlüssigen Verbindung zwischen den Federelementen 8, 9 können diese zusätzlich oder alternativ durch Löten, Schweißen, Kleben oder durch andersartige, insbesondere mechanische, Befestigungsmittel aneinander festgelegt werden.To generate the clamping force spring means 7 are provided, which are formed by two formed as wire spring elements spring elements 8, 9. These are positively connected with each other and formed as a common part to minimize manufacturing costs and simplify installation. As it turned out Fig. 2 In other words, the spring means 8, 9 give an annular spring element, which acts on the clamping claws 2, 3 toward each other to spring force. Instead of producing a positive connection between the spring elements 8, 9, these can additionally or alternatively be fixed to one another by soldering, welding, gluing or by other, in particular mechanical, fastening means.

Wie sich aus Fig. 1 ergibt, sind die Klemmklauen 2, 3 als voneinander separate Bauteile ausgebildet, die über zwei quer zur Einsteckrichtung E voneinander beabstandete Drehgelenke 10 gelenkig miteinander verbunden sind, wobei auch eine Ausführungsform analog zur DE 10 2005 063 239 A1 mit einstückig miteinander ausgebildeten Klemmklauen 2, 3 realisierbar ist, die vorzugsweise über ein Filmscharnier verschwenkbar sind.As it turned out Fig. 1 shows, the clamping jaws 2, 3 are formed as separate components, which are connected via two transversely to the insertion E spaced from each other hinges 10 articulated with each other, wherein also an embodiment analogous to DE 10 2005 063 239 A1 with integrally formed with each other clamping claws 2, 3 realized is, which are preferably pivotable via a film hinge.

Die Federmittel 7 sind in sich quer zur Längserstreckung des Kontaktierungssteckers 1 erstreckenden Nuten 11, 12 aufgenommen, die die Federmittel 7 führen. Die Federelemente 8, 9 greifen abschnittsweise in diese Nuten 11, 12 ein, wobei die Nuten 11, 12 derart angeordnet sind, dass sie sich in einer Ebene mit den nicht gezeigten Kontaktpunkten befinden, an denen die Kontaktelemente 6 von beiden Seiten an dem nicht dargestellten Kontaktträger anliegen. Somit liegen die Kontaktkräfte sowie die auf die Klemmklauen 2, 3 wirkende Klemmkraft in einer gemeinsamen Wirkebene. Die Kontaktelemente 6 verbinden Anschlussleitungen 29 eines Kabelbaums 30 mit den entsprechenden elektrischen Kontakten 27 des Kontaktträgers 25.The spring means 7 are in transversely to the longitudinal extent of the Kontaktierungssteckers 1 extending grooves 11, 12 received, which lead the spring means 7. The spring elements 8, 9 engage in sections in these grooves 11, 12, wherein the grooves 11, 12 are arranged such that they are in a plane with the contact points, not shown, at which the contact elements 6 from both sides to the not shown Contact carrier abut. Thus, the contact forces as well as acting on the clamping jaws 2, 3 clamping force in a common plane of action. The contact elements 6 connect connection lines 29 of a wiring harness 30 with the corresponding electrical contacts 27 of the contact carrier 25th

Anstelle der von Drahtfederelementen gebildeten Federmittel können auch Federmittel eingesetzt werden, die aus einem, vorzugsweise gummielastischen, Elastomermaterial ausgebildet sind. Auch ist es möglich, als Schrauben- oder Spiralfeder ausgebildete, die Klemmklauen 2, 3 auf Zug belastende Federelemente einzusetzen.Instead of the spring means formed by spring elements and spring means can be used, which are formed of a, preferably rubber-elastic, elastomeric material. It is also possible, designed as a helical or spiral spring, use the clamping claws 2, 3 on train loading spring elements.

Aus Fig. 1 ergibt sich weiterhin, dass an jeder Längsseite des Kontaktierungssteckers 1 ein von den Klemmklauen 2, 3 begrenzter, sich in Einsteckrichtung E erstreckender Aufnahmekanal 13, 14 vorgesehen ist. Die Aufnahmekanäle 13, 14 dienen zur jeweiligen Aufnahme eines Gegeneinsteckelementes, welches bevorzugt an der in Fig. 1 nicht gezeigten Kontaktierungssteckeraufnahme angeordnet ist. Die Gegeneinsteckelemente sorgen über entsprechende Anlaufschrägen dafür, dass die Klemmklauen 2, 3 beim Einschieben in die Kontaktierungssteckeraufnahme relativ zueinander um die Drehgelenke 10 verschwenkt werden, wobei bei diesem Verschwenkvorgang die Federmittel 7 gespannt und die Klemmklauen 2, 3 in Richtung aufeinander zu federkraftbeaufschlagt werden.Out Fig. 1 It also follows that on each longitudinal side of the Kontaktierungssteckers 1 one of the clamping jaws 2, 3 limited, extending in the insertion direction E receiving channel 13, 14 is provided. The receiving channels 13, 14 serve for receiving a respective Gegeneinsteckelementes, which preferably at the in Fig. 1 Not shown Kontaktierungssteckeraufnahme is arranged. The Gegeneinsteckelemente provide via corresponding run-in slopes that the clamping jaws 2, 3 when inserted into the Kontaktierungssteckeraufnahme be pivoted relative to each other about the pivot joints 10, wherein in this pivoting operation, the spring means 7 stretched and the clamping jaws 2, 3 in the direction towards each other to spring force.

Aus Fig. 1 ergibt sich weiterhin, dass die Klemmklauen 2, 3 in dem gezeigten, nicht eingesteckten, d.h. den Kontaktträger nicht kontaktierenden Zustand sich mittels einander zugeordneter Anschlagflächen 15, 16; 17, 18 aneinander abstützen. Die Anschlagflächen 15, 16 bzw. 17, 18 bilden Anschläge, die die Klemmklauen 2, 3 in einem in Einsteckrichtung E von den Drehgelenken 10 voneinander beabstandeten Bereich soweit voneinander beabstanden, dass die Kontaktelemente 6 nicht mit der von den Federmitteln 7 erzeugten Klemmkraft beaufschlagt werden, wodurch eine plastische und in dem gezeigten Ausführungsbeispiel zusätzlich eine elastische Verformung der Kontaktelemente 6 im gezeigten, nicht eingesteckten Zustand des Kontaktierungssteckers 1 mit Vorteil vermieden wird. Bei der Ausführungsform gemäß Fig. 1 werden die Klemmklauen 2, 3 in einem Bereich zwischen den quer zur Einsteckrichtung E voneinander beabstandeten Anschlagflächen 15, 16; 17, 18 soweit voneinander beabstandet, dass die Kontaktelemente der in der Zeichnungsebene oberen Klemmklaue 2 die gegenüberliegende Klemmklaue 3 und deren Kontaktelemente 6 nicht berühren und auch kein Kontakt zwischen den Kontaktelementen 6 der in der Zeichnungsebene unteren Klemmklaue 3 und der oberen Klemmklaue 2 oder den Kontaktelementen 6 der oberen Klemmklaue 2 gegeben ist.Out Fig. 1 further shows that the clamping jaws 2, 3 in the shown, not inserted, ie the contact carrier not contacting state by means of mutually associated abutment surfaces 15, 16; 17, 18 abut each other. The abutment surfaces 15, 16 and 17, 18 form stops which space the clamping claws 2, 3 apart from one another in an insertion direction E from the pivot joints 10 so that the contact elements 6 are not subjected to the clamping force generated by the spring means 7 whereby a plastic and in the embodiment shown additionally an elastic deformation of the contact elements 6 in the shown, not inserted state of the Kontaktierungssteckers 1 is advantageously avoided. In the embodiment according to Fig. 1 the clamping jaws 2, 3 in a region between the transversely to the insertion direction E spaced stop surfaces 15, 16; 17, 18 spaced apart so far that the contact elements of the upper plane in the drawing clamping jaw 2, the opposite clamping claw 3 and their contact elements 6 do not touch and no contact between the contact elements 6 of the drawing plane lower clamping jaw 3 and the upper clamping jaw 2 or the contact elements 6 of the upper clamping claw 2 is given.

Wie sich aus Fig. 1 ergibt, sind die Anschlagflächen 15, 16; 17, 18 stirnseitig an einstückig mit den Klemmklauen 2, 3 ausgebildeten Anschlagabschnitten 19, 20; 21, 22 ausgebildet, die sich im Wesentlichen senkrecht zur Einsteckrichtung E in Richtung der jeweils gegenüberliegenden Klemmklaue 2, 3 erstrecken.As it turned out Fig. 1 results, the stop surfaces 15, 16; 17, 18 at the end face integrally with the clamping claws 2, 3 formed stop portions 19, 20; 21, 22 are formed, which are substantially perpendicular to the insertion direction E in the direction of the respective opposite clamping claw 2, 3 extend.

Fig. 2 zeigt eine montierte Kontaktierungsverbindung 23. Zu erkennen ist der Kontaktierungsstecker 1, der mit seinem Montagehilfsgehäuse 24 in einer fest mit einem als Leiterplatte ausgebildeten Kontaktträger 25 verbundenen Kontaktierungssteckeraufnahme 26 aufgenommen ist. Zu erkennen ist, dass sich die Federmittel 7 nicht an der Kontaktierungssteckeraufnahme 26 abstützen. Die von den Kontakthaltern 4, 5 bzw. Klemmklauen 2, 3 getragenen, nur teilweise dargestellten Kontaktelemente 6 kontaktieren unmittelbar als Leiterbahnen ausgebildete elektrische Kontakte 27 auf beiden Flachseiten des als Leiterplatte ausgebildeten Kontaktträgers 25. Die Klemmklauen 2, 3 stützen sich unmittelbar mit Anlageflächen 28 an den elektrischen Kontakten 27 ab, wodurch die Lage der Kontaktelemente 6 zu den elektrischen Kontakten 27 definiert wird und eine Unabhängigkeit der von den Kontaktelementen 6 erzeugten Kontaktkräfte von den von den Federmitteln 7 erzeugten Klemmkräften resultiert. Fig. 2 shows a mounted Kontaktierungsverbindung 23. It can be seen the Kontaktierungsstecker 1, which is accommodated with its auxiliary assembly housing 24 in a fixedly connected to a printed circuit board formed as a contact carrier 25 Kontaktierungssteckeraufnahme 26. It can be seen that the spring means 7 are not supported on the Kontaktierungssteckeraufnahme 26. The contact elements 6 carried by the contact holders 4, 5 or clamping claws 2, 3 contact contact elements 6 formed directly as strip conductors on both flat sides of the contact carrier 25 formed as a printed circuit board. The clamping claws 2, 3 are directly supported by contact surfaces 28 the electrical contacts 27, whereby the position of the contact elements 6 is defined to the electrical contacts 27 and an independence of the contact forces generated by the contact elements 6 results from the clamping forces generated by the spring means 7.

Die in Fig. 1 gezeigten Anschlagflächen 15 bis 18, die eine Beschädigung der Kontaktelemente 6 im nicht eingesteckten Zustand des Kontaktierungssteckers 1 verhindern, sind in der Darstellung gemäß Fig. 2 aufgrund der Lage der Schnittlinie nicht zu erkennen.In the Fig. 1 shown stop surfaces 15 to 18, which prevent damage to the contact elements 6 in the non-inserted state of the Kontaktierungssteckers 1, are in the illustration according to Fig. 2 not recognizable due to the position of the cutting line.

Aus Fig. 2 ist die Position eines Gegeneinsteckelementes 31 zu erkennen, das einteilig mit der Kontaktierungssteckeraufnahme 26 ausgebildet ist, und das beim Einschieben in den zugehörigen Aufnahmekanal das von den Klemmklauen 2, 3 gebildete Klemmmaul aufspreizt, derart, dass die Klemmklauen 2, 3 um die zugehörigen Drehgelenke 10 verschwenkt werden. Out Fig. 2 the position of a Gegeneinsteckelementes 31 can be seen, which is formed integrally with the Kontaktierungssteckeraufnahme 26, and spreads when inserted into the associated receiving channel formed by the clamping jaws 2, 3 clamping jaw, such that the clamping jaws 2, 3 are pivoted about the associated pivot joints 10.
