Description

Die Erfindung betrifft einen Steckverbinder nach der Gattung des unabhängigen Anspruchs 1.The invention relates to a connector according to the preamble of independent claim 1.

Stand der TechnikState of the art

Ein gattungsgemäßer Steckverbinder geht aus der DE 10 2006 030 784 A1 hervor. Bei diesem Steckverbinder wird ein in einem Steckverbinder-Grundelement angeordnetes Kontaktelement mittels einer Sekundär-Verriegelung gehalten. Hierzu ist in dem Kontaktelement wenigstens eine quer zur Steckrichtung angeordnete Sekundär-Verriegelungsausnehmung vorgesehen, in welche eine Verriegelungsnocke eines Sekundär-Verriegelungselements in der Verriegelungsposition des Sekundär-Verrieglungselements eingreift. Das Kontaktelement dieses Steckverbinders weist eine Crimpfahne auf, die zur Kontaktierung eines abisolierten elektrischen Leiters dient.A generic connector goes out of the DE 10 2006 030 784 A1 out. In this connector, a arranged in a connector base element contact element is held by a secondary latch. For this purpose, at least one transverse to the insertion direction arranged secondary locking recess is provided in the contact element, in which engages a locking cam of a secondary locking element in the locking position of the secondary locking element. The contact element of this connector has a Crimpfahne, which serves for contacting a stripped electrical conductor.

Derartige Stecker werden auch im Kraftfahrzeugbereich eingesetzt. In Kraftfahrzeugen unterliegen die Stecker und insbesondere auch die Crimpanschlüsse der Leiter erheblichen Belastungen, beispielsweise Rüttelbelastungen, Vibrationsbelastungen und dergleichen. Dies führt zu einer erheblichen Belastung des Übergangsbereichs zwischen Messer- bzw. Federkontakten und dem Crimpbereich. Aufgrund dieser Vibrationen kann es beispielsweise zu einem Bruch kommen. Darüber hinaus wurde festgestellt, dass aufgrund großer Vibrationen eine Kontaktkorrosion eines Kupferleiters in dem Crimpanschluss auftritt, die isolierend wirkt und dadurch den Widerstand in nicht akzeptabler Weise erhöht.Such connectors are also used in the automotive field. In motor vehicles, the plugs and in particular the crimp terminals of the conductors are subject to considerable loads, for example shaking loads, Vibration loads and the like. This leads to a considerable load on the transition region between knife or spring contacts and the crimping area. For example, these vibrations can cause breakage. In addition, it has been found that due to large vibrations, contact corrosion of a copper conductor occurs in the crimp terminal, which acts as an insulator and thereby unacceptably increases the resistance.

Der Erfindung liegt daher die Aufgabe zugrunde, einen solchen Steckverbinder so weiterzubilden, dass die vorbeschriebenen Nachteile nicht auftreten und dass insbesondere ein solcher Steckverbinder auch erheblichen Rüttelbelastungen und/oder Vibrationsbelastungen, wie sie in Fahrzeugen auftreten, ausgesetzt werden kann.The invention is therefore the object of developing such a connector so that the above-described disadvantages do not occur and that in particular such a connector and considerable vibration loads and / or vibration loads, such as occur in vehicles can be suspended.

Die Aufgabe wird durch die im unabhängigen Anspruch 1 angegebenen Merkmale gelöst.The object is solved by the features specified in the independent claim 1.

Offenbarung der ErfindungDisclosure of the invention

Der erfindungsgemäße Steckverbinder ist durch ein endseitig eines Crimpbereichs angeordnetes Fixierelement gekennzeichnet, welches in eine gegengleiche Ausnehmung in dem Steckverbindergrundelement eingreift.The connector according to the invention is characterized by a fixed end of a crimping fixation, which engages in a gegengleiche recess in the connector base.

Grundidee der Erfindung ist es, den Steckverbinder nicht nur mittels der Primär- und Sekundär-Verriegelung zu sichern und zu fixieren, sondern ein Fixierelement vorzusehen, welches in einem maximal möglichen Abstand von dem Sekundär-Verriegelungselement angeordnet ist und so eine Fixierung des Kontaktelements in dem Steckverbindergrundelement an zwei Punkten und insbesondere eine Fixierung des Crimpbereichs des Kontaktelements sicherstellt.The basic idea of the invention is not only to secure and fix the connector by means of the primary and secondary locking, but to provide a fixing element which is arranged at a maximum possible distance from the secondary locking element and thus fixes the contact element in the Connector base element at two points and in particular ensures a fixation of the crimping of the contact element.

Dabei wird eine Arretierung dieses Fixierelements in der gegengleichen Ausnehmung in der Verriegelungsposition des Sekundär-Verriegelungselements ermöglicht, sodass letzten Endes durch die Betätigung des Sekundär-Verriegelungselements gleichzeitig auch eine Fixierung und Arretierung des Fixierelements in der Ausnehmung in dem Steckverbindergrundelement auf sehr vorteilhafte Weise erreicht wird.In this case, a locking of this fixing is made possible in the opposite recess in the locking position of the secondary locking element, so that at the same time a fixation and locking of the fixing element in the recess in the connector base element is achieved in a very advantageous manner by the actuation of the secondary locking element.

Dabei wirkt das Fixierelemnt mit der gegengleichen Ausnehmung so zusammen, dass das Fixierelement durch die Bewegung des Kontaktelements in Steckrichtung an einer Fläche der gegengleichen Ausnehmung in dem Steckverbindergrundelement unter Ausübung einer Vorspannung zur Anlage kommt. Durch diese vorgespannte Positionierung wird ein rüttel- und vibrierfestes Arretieren des Kontaktelements in dem Steckverbindergrundelement erreicht.In this case, the Fixierelemnt cooperates with the opposite recess so that the fixing element comes by the movement of the contact element in the insertion direction on a surface of the opposite recess in the connector base element by applying a bias to the plant. By this biased positioning a vibration and vibration resistant locking of the contact element is achieved in the connector base element.

J Vorteilhafte Weiterbildungen und Ausgestaltungen des erfindungsgemäßen Steckverbinders sind Gegenstand der auf Anspruch 1 rückbezogenen Unteransprüche.Advantageous developments and refinements of the connector according to the invention are the subject of the dependent claims on claim 1.

So sieht eine vorteilhafte Ausgestaltung vor, dass die wenigstens eine Sekundär-Verriegelungsausnehmung konisch ausgebildet ist und der Verriegelungsnocken in Bezug auf diese Sekundär-Verriegelungsausnehmung ein (geringfügiges) Übermaß aufweist, sodass bei einem Eingreifen des Sekundär-Verriegelungsnockens in die Sekundär-Verriegelungsausnehmung bei einer gleichzeitigen Bewegung des Kontaktelements im Steckverbindergrundelement parallel zur Steckrichtung ein Festklemmen des Verriegelungsnockens in der Sekundär-Verriegelungsausnehmung hervorgerufen wird.Thus, an advantageous embodiment provides that the at least one secondary locking recess is conical and the locking cam with respect to this secondary locking recess has a (slight) oversize, so that upon engagement of the secondary locking cam in the secondary locking recess at a simultaneous Movement of the contact element in the connector base parallel to the insertion direction a clamping of the locking cam in the secondary locking recess is caused.

Beim Eingreifen des Verriegelungsnockens in die Sekundär-Verriegelungsausnehmung wird also zunächst eine minimale Bewegung des Kontaktelements in dem Steckverbinder-Grundelement parallel zur Steckrichtung hervorgerufen und sodann durch einen vollständigen Eingriff des Nockens in die Sekundär-Verriegelungsausnehmung das Kontaktelement in dem Steckverbindergrundelement gesichert.Upon engagement of the locking cam in the secondary locking recess so a minimal movement of the contact element in the connector base element is initially caused parallel to the insertion direction and then secured by a complete engagement of the cam in the secondary locking recess, the contact element in the connector base.

Die Anordnung des Fixierelements an dem Kontaktelement kann rein prinzipiell auf die unterschiedlichste Art und Weise geschehen.The arrangement of the fixing element on the contact element can be done purely in principle in a variety of ways.

Eine sehr vorteilhafte Ausführungsform, die insbesondere auch eine leichte Kontaktierung des Leiters in dem Crimpbereich des Kontaktelementes ermöglicht, sieht vor, dass das Fixierelement an einer sich senkrecht zur Steckrichtung erstreckenden Abbiegung anzuordnen. Durch diese Anordnung wird der maximale Öffnungsquerschnitt für die Aufnahme des Leiters im Crimpbereich nicht nur bereitgestellt, sondern die Abbiegung erfüllt sogar die Aufgabe einer Einführhilfe für den Leiter in den Crimpbereich, da bei einer Fehlpositionierung des Leiters dieser an der Abbiegung entlanggeführt wird, bis er in den Crimpbereich gelangt.A very advantageous embodiment, which in particular also enables easy contacting of the conductor in the crimp region of the contact element, provides for arranging the fixing element on a bend extending perpendicularly to the plug-in direction. By this arrangement, the maximum opening cross section for receiving the conductor in the crimping area is not only provided, but the bend even fulfills the task of an insertion aid for the conductor in the crimping area, as in a faulty positioning of the conductor, this is guided along the turn until he in reaches the crimping area.

Bevorzugt schließt die Abbiegung einen Winkel von 90° mit der Steckrichtung ein. Es ist allerdings auch möglich, den Winkel geringfügig kleiner als 90° auszubilden. Ein Winkel von 90° ermöglicht die beste Ausbildung eines Widerlagers.Preferably, the bend includes an angle of 90 ° with the plugging direction. However, it is also possible to form the angle slightly smaller than 90 °. An angle of 90 ° allows the best training of an abutment.

Das Fixierelement selbst weist vorzugsweise eine im Wesentlichen T-förmige Gestalt auf. Hierdurch wird aufgrund der gegengleichen Ausbildung in dem Steckverbindergrundelement auch eine seitliche, das heißt senkrecht zur Steckrichtung wirkende Fixierung auf sehr vorteilhafte Weise erzielt. Gemäß einer vorteilhaften Ausführungsform ist an dem Kontaktelement eine Arretierfeder zur Einfederung in eine in dem Steckverbinder-Grundelement vorgesehene Primär-Verriegelungsausnehmung angeordnet.The fixing element itself preferably has a substantially T-shaped form. As a result, a lateral, that is perpendicular to the direction of insertion fixation achieved in a very advantageous manner due to the opposite education in the connector base. According to an advantageous embodiment, a locking spring for deflection into a provided in the connector base element primary locking recess is arranged on the contact element.

Die Auszugskraft kann durch eine Variation der Anzahl der Ausnehmungen, in welche jeweils Verriegelungsnocken des Sekundär-Verriegelungselements in der Verriegelungsposition des Sekundär-Verriegelungselements eingreifen, an vorgegebene Auszugskraft-Anforderungen angepasst werden. Dadurch sind auch sehr hohe Auszugskräfte beispielsweise von 100 Newton oder mehr erreichbar.The pull-out force can by a variation of the number of recesses, in which each locking cam of the secondary locking element engage in the locking position of the secondary locking element, be adapted to predetermined pull-out requirements. As a result, very high pull-out forces of, for example, 100 Newton or more can be achieved.

Eine Ausgestaltung sieht vor, dass im Steckverbinder-Grundelement eine Sekundär-Verriegelungselement-Ausnehmung vorgesehen ist, welche das Sekundär-Verriegelungselement in der Verriegelungsposition aufnimmt. Das Sekundär-Verriegelungselement wird mit dieser Maßnahme in der Verriegelungsposition integraler Bestandteil des Steckverbinders.One embodiment provides that a secondary locking element recess is provided in the connector base element, which receives the secondary locking element in the locking position. The secondary locking element is with this measure in the locking position an integral part of the connector.

Eine besonders vorteilhafte Ausgestaltung sieht vor, dass das Sekundär-Verriegelungselement am vorderen Ende eine Codierfläche aufweist, die ein Stecken des Steckverbinders verhindert, wenn das Sekundär-Verriegelungselement außerhalb der Verriegelungsposition positioniert ist. Mit dieser Maßnahme wird die Sicherheit der Steckverbindung erhöht. Das Einstecken des erfindungsgemäßen Steckverbinders in den zum erfindungsgemäßen Steckverbinder korrespondierenden zweiten Steckverbinder ist nur möglich, wenn das Sekundär-Verriegelungselement in der Verriegelungsposition positioniert ist.A particularly advantageous embodiment provides that the secondary locking element at the front end has a coding surface, which prevents plugging of the connector when the secondary locking element is positioned outside the locking position. With this measure, the safety of the connector is increased. The insertion of the connector according to the invention in the connector corresponding to the second connector according to the invention is only possible if the secondary locking element is positioned in the locking position.

Eine vorteilhafte Ausführungsform sieht dabei vor, dass im vorderen Bereich des Sekundär-Verriegelungselements wenigstens eine in Steckrichtung angeordnete Codier-Rippe vorgesehen ist. Die Codier-Rippe verhindert eine fehlerhafte Herstellung der Steckverbindung, wenn das Sekundär-Verriegelungselement in der Verriegelungsposition positioniert ist.An advantageous embodiment provides that in the front region of the secondary locking element at least one arranged in the insertion direction coding rib is provided.

Beschreibung von AusführungsbeispielenDescription of exemplary embodiments

Ein als Ganzer mit 100 bezeichneter, in den Figuren 1 bis 4 in verschiedenen Ansichten dargestellter Steckverbinder weist ein Steckverbindergrundelement 110 auf, das aus einem isolierenden Material, insbesondere aus Kunststoff, besteht. In diesem Steckverbindergrundelement 110 ist ein Kontaktelement 200 angeordnet. Ferner ist in dem Steckverbindergrundelement 110 ein Sekundär-Verriegelungselement 300 angeordnet, wobei das Sekundär-Verriegelungselement 300 Verriegelungsnocken 305, 306 aufweist, die im verriegelten Zustand (Fig. 2, Fig. 4) in Sekundär-Verriegelungsausnehmungen 205, 206 des Kontaktelements 200 eingreifen. Wie insbesondere der Fig. 3 und der Fig. 4 zu entnehmen ist, ist die Sekundär-Verriegelungsausnehmung 205, 206 konisch ausgebildet, wohingegen wenigstens ein Verriegelungsnocken 305 gegenüber der Sekundär-Verriegelungsausnehmung 205 ein (geringfügiges) Übermaß aufweist, das heißt, etwas größer ist als die Sekundär-Verriegelungsausnehmung 205. Die konische Ausbildung der Sekundär-Verriegelungsaufnahmen 205, 206 bewirkt, dass während des Eingreifens der Verriegelungsnocken 305, 306 eine Bewegung des Kontaktelements entgegen der Steckrichtung, die in Fig. 3 und Fig. 4 mit einem Pfeil R gekennzeichnet ist, hervorgerufen wird. Nach vollständigem Eingriff der Verriegelungsnocken 305, 306 in die Sekundär-Verriegelungsausnehmung 205, 206, der durch Ausübung einer Kraft entlang eines in Fig. 3 mit Pfeil 301 bezeichneten Richtung bewirkt wird, ist das Kontaktelement 300 in dem Steckverbindergrundelement 200 fixiert und arretiert. Die Ausübung einer entgegen der Steckrichtung R wirkenden Bewegung des Kontaktelements 200 in dem Steckverbindergrundelement 110 bewirkt aber gleichzeitig auch, dass ein an dem Kontaktelement (vergleiche Fig. 6, Fig. 7) angeordnetes Fixierelement 215 in eine gegengleiche Ausnehmung 115 des Steckverbindergrundelements 110 eingreift und dort an eine Anschlagfläche 116 unter Ausübung einer Vorspannung zur Anlage kommt (Fig. 1, Fig. 2). Durch diese Vorspannung wird eine Fixierung des Kontaktelements 200 in dem Steckverbindergrundelement 110 an einer zweiten Position bewerkstelligt. Auf diese Weise ist das Kontaktelement 200 an zwei Stellen in dem Steckverbindergrundelement 110 fixiert, zum einen durch die Sekundär-Verriegelung mittels der Nocken 305, 306 in den entsprechenden konischen Öffnungen 205, 206 in dem Kontaktelement 200, zum anderen durch das Fixierelement 215 in den Öffnungen 115 des Steckverbindergrundelements 110 unter Vorspannung. Die Fixierung durch das Fixierelement 215 bewirkt insbesondere, dass auch bei einer starken Vibrationen oder Rüttelbewegungen ausgesetzten Betriebsweise des Steckverbinders 100 kein Bruch des Kontaktelements 200, beispielsweise im Bereich unmittelbar zwischen den Sekundär-Verriegelungsausnehmungen 205, 206 und den Crimpflügeln 240 auftritt und dass insbesondere auch keine Kontaktkorrosion im Crimpbereich durch fortwährende sehr starke Vibrationen entsteht. Vielmehr wird das Kontaktelement 200 und insbesondere der Crimpbereich völlig unverrückbar und auch gegenüber Vibrationen ortsfest in seiner Position in dem Steckverbindergrundelement 110 gehalten.One as a whole with 100 designated, in the FIGS. 1 to 4 shown in various views connector has a connector base 110, which consists of an insulating material, in particular of plastic. In this connector base element 110, a contact element 200 is arranged. Furthermore, a secondary locking element 300 is arranged in the plug connector base element 110, wherein the secondary locking element 300 has locking cams 305, 306, which in the locked state (FIG. Fig. 2 . Fig. 4 ) engage in secondary locking recesses 205, 206 of the contact element 200. How the particular Fig. 3 and the Fig. 4 it can be seen, the secondary locking recess 205, 206 is conical, whereas at least one locking cam 305 relative to the secondary locking recess 205 has a (slight) oversize, that is, is slightly larger than the secondary locking recess 205. The conical configuration of the secondary locking receptacles 205, 206 causes, during the engagement of the locking cams 305, 306, a movement of the contact element against the plugging direction, which in Fig. 3 and Fig. 4 is indicated with an arrow R, is caused. After complete engagement of the locking cams 305, 306 in the secondary locking recess 205, 206, which by applying a force along a in Fig. 3 caused by arrow 301, the contact element 300 is fixed and locked in the connector base 200. However, the exercise of a counter to the direction of insertion R acting movement of the contact element 200 in the connector base 110 causes at the same time that a on the contact element (see Fig. 6 . Fig. 7 ) arranged fixing element 215 engages in a gegengleiche recess 115 of the connector base member 110 and there comes to a stop surface 116 while exerting a bias to the plant ( Fig. 1 . Fig. 2 ). By this biasing a fixation of the contact element 200 is accomplished in the connector base 110 at a second position. In this way, the contact element 200 is fixed in two places in the connector base element 110, on the one hand by the secondary locking means of the cams 305, 306 in the corresponding conical openings 205, 206 in the contact element 200, on the other hand by the fixing element 215 in the Openings 115 of the connector base 110 under bias. The fixation by the fixing element 215 causes in particular that even with a strong vibrations or shaking exposed operation of the connector 100 no breakage of the contact element 200, for example, in the area directly between the secondary locking recesses 205, 206 and the Crimflügeln 240 occurs and that in particular no Contact corrosion in the crimping area is caused by continuous very strong vibrations. Rather, the contact element 200 and in particular the crimping area is held completely immovable and also stationary with respect to vibrations in its position in the connector base element 110.

Das Steckverbindergrundelement 110 weist auf an sich bekannte Weise eine Primärverriegelungsausnehmung 127 auf, die durch Spritzgießen herstellbar ist oder durch Fräsen und dergleichen. Das Sekundär-Verriegelungselement 300 weist an seiner den Kontaktfedern 210 zugewandten Seite des Kontaktelements 200, das heißt steckseitig eine Codierrippe 330 auf, die in Steckrichtung R verläuft. Diese wenigstens eine Codierrippe 330 verhindert einen fehlerhaften Steckvorgang, wenn das Sekundär-Verriegelungselement 300 bereits in der Verriegelungsposition positioniert ist.The connector base element 110 has, in a known manner, a primary locking recess 127, which can be produced by injection molding or by milling and the like. The secondary locking element 300 has on its side facing the contact springs 210 of the contact element 200, that is, on the plug side an encoder rib 330, which extends in the plugging direction R. This at least one coding rib 330 prevents an erroneous mating operation when the secondary locking element 300 is already positioned in the locking position.

Darüber hinaus kann auch an dem Steckverbindergrundelement 110 ein Codierelement 111 angeordnet sein, dass insbesondere eine falsche Orientierung des Steckverbinders in Bezug zu einem korrespondierenden Steckverbinder (nicht dargestellt) verhindert. Dieses Codierelement 111 wirkt auch mit dem Sekundär-Verriegelungselement 300 zusammen. An der Codierrippe 330 ist nämlich stirnseitig eine Codierfläche 332 angeordnet, die ein Stecken des Steckverbinders verhindert, wenn das Sekundär-Verriegelungselement 300 außerhalb der Verriegelungsposition positioniert ist, wie es beispielsweise in Fig. 1 und Fig. 3 dargestellt ist. In diesem Falle schlägt ein komplementärer (nicht dargestellter) Steckverbinder an die Codierfläche 332 an. Erst im verriegelten Zustand (dargestellt in Fig. 2 und Fig. 4) fluchtet die Codierrippe 330 mit dem Codierelement 111 des Steckverbindergrundelements 110 und die Codierfläche 332 steht nicht mehr über dieses Codierelement 111 über. In diesem Fall liegt das Sekundär-Verriegelungselement 300 in einer in dem Steckverbindergrundelement 110 angeordneten Sekundär-Verriegelungselement-Ausnehmung 119 und wird von dieser aufgenommen.In addition, a coding element 111 can also be arranged on the plug connector base element 110, which in particular prevents incorrect orientation of the plug connector relative to a corresponding plug connector (not illustrated). This coding element 111 also cooperates with the secondary locking element 300. On the Codierrippe 330 namely a coding surface 332 is arranged, which prevents plugging of the connector, when the secondary locking member 300 is positioned outside the locking position, as for example in FIG Fig. 1 and Fig. 3 is shown. In this case, a complementary connector (not shown) abuts the coding surface 332. Only in the locked state (shown in Fig. 2 and Fig. 4 ), the coding rib 330 is aligned with the coding element 111 of the connector base element 110, and the coding surface 332 no longer communicates with this coding element 111. In this case, the secondary locking element 300 lies in a secondary locking element recess 119 arranged in the connector base element 110 and is received thereby.

In dem Steckverbindergrundelement 110 sind darüber hinaus ebenfalls Codierrippen 191, 192 angeordnet, die eine fehlerhafte Steckung mit einem entsprechenden weiteren Steckverbinder verhindern (Fig. 5).In addition, coding ribs 191, 192 are arranged in the connector base element 110, which prevent an incorrect connection with a corresponding further connector ( Fig. 5 ).

Das Kontaktelement 200 weist auf seiner den Kontaktelementen, im gezeigten Fall sind dies Federelemente 210, zugewandten Seite einen im Wesentlichen rechteckigen Positionierrahmen 211 mit einer Öffnung 212 auf. Dieser Positionierrahmen findet in einer entsprechenden Ausnehmung 123 des Steckverbinderg rundelements 110 Aufnahme und ermöglicht eine exakte Positionierung der Federelemente 210 auf an sich bekannte Weise.The contact element 200 has on its contact elements, in the case shown, this spring elements 210, side facing a substantially rectangular positioning frame 211 with an opening 212. This positioning frame is in a corresponding recess 123 of the Steckverbinderg round member 110 receiving and allows exact positioning of the spring elements 210 in a known manner.

Das Kontaktelement 200 weist darüber hinaus eine Arretierfeder 220 auf, die ebenfalls auf an sich bekannte Weise im eingeschobenen Zustand des Kontaktelements 200 in die Primärverriegelungsausnehmung 127 einfedert und das Kontaktelement 200 gegen ein Herausziehen an einem Primärverriegelungswiderlager 128 auf an sich bekannte Weise abstützt.The contact element 200 also has a locking spring 220, which also springs in known manner in the inserted state of the contact element 200 in the Primärverriegelungsausnehmung 127 and the contact element 200 is supported against pulling on a Primärverriegelungswiderlager 128 in a known per se.

Wie insbesondere in Fig. 6 und Fig. 7 dargestellt ist, ist das Fixierelement 215 an einer gebogenen Abbiegung 216 angeordnet, die mit der Steckrichtung R einen Winkel von 90° einschließt. Dies hat den Vorteil, dass die Öffnung zur Einführung eines Kabels 204 leicht zugänglich ist. Das Kabel wird auf an sich bekannte Weise abisoliert, wobei der abisolierte Teil im Crimpbereich 240 durch Crimpen kontaktiert wird. Der nicht abisolierte Kabelmantel wird in einem Klemmbereich 243 geklemmt und somit eine Zugentlastung bereitgestellt.As in particular in Fig. 6 and Fig. 7 is shown, the fixing element 215 is arranged on a curved bend 216 which forms an angle of 90 ° with the plugging direction R. This has the advantage that the opening for the introduction of a cable 204 is easily accessible. The cable is stripped in a known manner, the stripped part is contacted in the crimping area 240 by crimping. The non-stripped cable sheath is clamped in a clamping region 243 and thus provided a strain relief.

Der Vorteil des vorbeschriebenen Steckverbinders 100 besteht darin, dass durch die Fixierung des Steckverbinders mittels Primär-Verriegelungselement, gebildet aus Feder 220 und Primärverriegelungswiderlager 125, Sekundär-Verriegelungselement, gebildet aus Sekundär-Verriegelungsausnehmungen 205, 206, die konisch ausgebildet sind, und Nocken 305, 306 des Sekundär-Verriegelungselements 300, deren wenigstens eine gegenüber einer Sekundär-Verriegelungsausnehmung 205 ein (geringfügiges) Übermaß aufweist, und gebildet durch das Fixierelement 215, welches in eine entsprechende gegengleiche Ausnehmung 115 in dem Sekundär-Verriegelungsgrundelement 110 eingreift und eine vorgespannte Fixierung des Kontaktelements 200 in dem Steckverbindergrundelement 110 vermittelt, eine Fixierung und Arretierung an mehreren Punkten des Kontaktelements 200 in dem Steckverbindergrundelement 110 und insbesondere auch endseitig des Crimpbereichs erzielt wird. Dabei erweist sich die gebogene rechtwinklige Abbiegung 216 auch im Hinblick auf die Ausübung der Vorspannung als besonders vorteilhaft, da hierdurch eine Federwirkung erzielbar ist. Das Kontaktelement 200 ist auf diese Weise an zwei Punkten, die voneinander räumlich beabstandet sind, nämlich der Sekundär-Verriegelung, gebildet durch die Sekundär-Verriegelungsausnehmung 205, 206 und die Nocken 305, 306 und das endseitig des Crimpbereichs angeordnete Fixierelement 215, welches in die gegengleiche Öffnung 115 des Sekundär-Verriegelungsgrundelements 110 eingreift, fixiert. Hierdurch wird eine Vibration des Crimpbereichs 240 und des Klemmbereichs 242 verhindert, der zu einer störenden Kontaktkorrosion und damit einer Unterbrechung des elektrischen Kontakts durch Widerstandserhöhung oder sogar zu einem Bruch des Kontaktelements 200 führen kann.The advantage of the above-described connector 100 is that by fixing the connector by means of primary locking element formed from spring 220 and primary locking abutment 125, secondary locking element formed from secondary locking recesses 205, 206, which are conical, and cams 305, 306 of the secondary locking element 300, whose at least one opposite a secondary locking recess 205 has a (slight) oversize, and formed by the fixing element 215, which engages in a corresponding opposite recess 115 in the secondary locking base element 110 and a prestressed Fixing the contact element 200 in the connector base element 110 mediates, a fixing and locking at a plurality of points of the contact element 200 in the connector base element 110 and in particular also ends of the crimping is achieved. In this case, the curved right-angled bend 216 also proves to be particularly advantageous with regard to the exertion of the prestressing, as a result of this a spring effect can be achieved. The contact element 200 is in this way at two points spaced from each other spatially, namely the secondary locking, formed by the secondary locking recess 205, 206 and the cams 305, 306 and the end of the crimping region arranged fixing element 215, which in the opposite opening 115 of the secondary locking element 110 engages fixed. This prevents vibration of the crimping area 240 and of the clamping area 242, which can lead to disruptive contact corrosion and thus interruption of the electrical contact due to resistance increase or even breakage of the contact element 200.

Das Fixierelement ist im Wesentlichen T-förmig ausgebildet. Hierdurch wird nicht nur die Auflagefläche in Steckrichtung vergrößert, sondern auch eine optimale Arretierung senkrecht zur Steckrichtung vermittelt.The fixing element is essentially T-shaped. As a result, not only the contact surface is increased in the insertion direction, but also conveys an optimal locking perpendicular to the direction of insertion.

An dieser Stelle ist zu bemerken, dass die Anzahl der Sekundär-Verriegelungsausnehmungen 205, 206 abhängig von der Ausziehkraft gewählt wird. Bei kleinerer Ausziehkraft genügt eine, bei größerer Ausziehkraft werden zwei Ausnehmungen gewählt. Darüber hinaus könnten auch mehr als zwei Ausnehmungen vorgesehen sein.At this point, it should be noted that the number of secondary locking recesses 205, 206 is selected depending on the pull-out force. If the pull-out force is smaller, one of the two pull-outs is sufficient. In addition, more than two recesses could be provided.
