Description

Die Erfindung geht aus von einen elektrischer Steckverbinder nach dem Oberbegriff des unabhängigen Anspruchs 1.The invention relates to an electrical connector according to the preamble of the independent claim 1.

Derartige elektrischer Steckverbinder werden benötigt um elektrische Leitungen oder Kabel miteinander reversibel zu verbinden. Dadurch soll ein elektrischer Kontakt zwischen einer ersten Leitung oder einem ersten Kabel und einer zweiten Leitung oder einem zweiten Kabel hergestellt werden.Such electrical connectors are needed to reversibly connect electrical cables or cables with each other. This is intended to produce an electrical contact between a first line or a first cable and a second line or a second cable.

Die meist aus einem isolierenden Grundkörper gebildeten Steckverbinder verfügen über eine Vielzahl von elektrischen Kontaktelementen, welche durch Kontaktöffnungen mit den elektrischen Kontaktelementen eines Gegensteckverbinders verbindbar sind. Je nach Baugröße sind verschiedene Ausführungsformen von elektrischen Steckverbindern aus dem Stand der Technik bekannt. Abhängig von der Größe und Ausführung der elektrischen Kontaktelemente ist auch die Fixierung der Kontaktelemente im Steckverbinder realisiert.The most commonly formed of an insulating body connectors have a plurality of electrical contact elements, which are connectable by contact openings with the electrical contact elements of a mating connector. Depending on the size of various embodiments of electrical connectors of the prior art are known. Depending on the size and design of the electrical contact elements and the fixation of the contact elements in the connector is realized.

Stand der TechnikState of the art

Die DE 14 65 124 B2 zeigt einen elektrischen Steckverbinder, bestehend aus einem Gehäuseblock mit in Einschubrichtung begrenzten Längskanälen, in die aus einem Stanzteil gebogene Kontakthülsen, deren Anschlußdrähte sich in Längsrichtung erstrecken, einschiebbar und hinter einem Absatz des Längskanals lösbar verrastbar sind, und mit seitlich in die Kontakthülsen einmündenden Einstecköffnungen für die Steckerstifte eines Anschlußsteckers, mit an sich bekannte Kontakthülsen nach Art einer Rinne mit einem einen Ausschnitt aufweisenden Boden und mit Seitenwänden, die die Kontaktflächen für den von oben her senkrecht zum Boden einführbaren Steckerstift bilden und vorn und hinten durch hakenförmige Fortsätze verbunden sind. Durch eine vom Vorderende des Ausschnitts sich nach rückwärts in Richtung zum Anschlußdraht erstreckende, mit ihrem freien Ende bis unterhalb des Steckerstifts reichende, nach außen abgebogene Rastzunge, und durch eine kleine Öffnung zum Einführen eines Lösewerkzeugs in der den Längskanal begrenzenden Vorderwand des Gehäuseblocks in Richtung auf den Rastabsatz des Längskanals.The DE 14 65 124 B2 shows an electrical connector consisting of a housing block with limited in the insertion direction longitudinal channels, in the punched part of a bent contact sleeves whose connecting wires extend in the longitudinal direction, and behind a shoulder of the longitudinal channel are releasably latched, and laterally in the contact sleeves opening insertion openings for the plug pins of a connector plug, known per se contact sleeves in the manner of a channel with a cutout having bottom and side walls that form the contact surfaces for the top of the insertable perpendicular to the ground pin pin and front and Rear are connected by hook-shaped extensions. By a from the front end of the section extending backwards in the direction of the connecting wire, reaching with its free end to below the pin, outwardly bent latching tongue, and through a small opening for inserting a release tool in the longitudinal channel delimiting the front wall of the housing block in the direction of the locking shoulder of the longitudinal channel.

Aus der DE 20 2006 018 019 U1 ist eine Steckverbindung mit einem ersten Steckverbinderteil, das als Steckerteil ausgebildet ist und mit einem zweiten Steckerteil, das als Buchsenteil ausgebildet ist, bekannt. Das Steckverbinderteil weist je Leiter wenigstens einen oder mehr isolationsdurchdringende Kontakte und ein Betätigungselement zum Kontaktieren der Leiter mit den isolationsdurchdringenden Kontakten auf. Das Betätigungselement weist wenigstens eine oder mehrere Aufnahmekonturen zur Aufnahme der Leiter auf, welche eine sich verjüngende Form zum Zentrieren des jeweils zu kontaktierenden Leiters aufweisen.From the DE 20 2006 018 019 U1 is a plug connection with a first connector part, which is designed as a plug part and with a second plug part, which is designed as a socket part known. The connector part has at least one or more insulation piercing contacts per conductor and an actuating element for contacting the conductors with the insulation piercing contacts. The actuating element has at least one or more receiving contours for receiving the conductors, which have a tapered shape for centering the respective conductor to be contacted.

Die WO 02/15339 A1 betrifft einen elektrischen Steckverbinder, umfassend ein Steckverbindergehäuse, eine Leiterplatte mit zwei Sätzen von Kontaktelementen, wobei der erste Satz der Kontaktelemente auf der Vorderseite der Leiterplatte angeordnet ist und in eine Öffnung im Steckverbindergehäuse ragt. Der zweite Satz von Kontaktelementen ist auf der Rückseite der Leiterplatte angeordnet und die Kontaktelemente sind als Schneid-Klemm-Kontakte ausgebildet. Der Steckverbinder umfasst einen Kabelmanager, der eine durchgehende Öffnung aufweist und auf der Vorderseite mit Führungen für mit den Schneid-Klemm-Kontakten zu kontaktierende Adern ausgebildet ist, wobei die Führungen im Bereich der Schneid-Klemm-Kontakte mit vertieften Aufnahmen für die Schneid-Klemm-Kontakte ausgebildet sind und der Kabelmanager mit dem Steckverbindergehäuse verrastbar ist.The WO 02/15339 A1 relates to an electrical connector comprising a connector housing, a printed circuit board with two sets of contact elements, wherein the first set of the contact elements is arranged on the front side of the printed circuit board and projects into an opening in the connector housing. The second set of contact elements is arranged on the back of the circuit board and the contact elements are designed as insulation displacement contacts. The connector comprises a cable manager having a through opening and formed on the front with guides for to be contacted with the insulation displacement contacts wires, the guides in the region of the insulation displacement contacts with recessed receptacles for the insulation displacement Contacts are formed and the cable manager is latched to the connector housing.

Nachteilig an den aus dem Stand der Technik bekannten Steckverbindern wirkt sich die Fixierung der Kontaktelemente aus. Die meisten bekannten Steckverbinder verrasten oder verklemmen lediglich das elektrische Kontaktelement im Isolierkörper des Steckverbinders. Hier kann eine zu große mechanische Belastung eines angeschlossenen Kabels zur Beeinträchtigung der Verbindung zwischen Kabel und Kontaktelement führen. Im schlimmsten Fall kann das Kabel vom elektrischen Kontaktelement abreisen und die elektrische Verbindung getrennt werden, was einen Ausfall des Steckverbinders zur Folge hätte.A disadvantage of the connectors known from the prior art, the fixation of the contact elements affects. Most known connectors lock or jam only the electrical contact element in the insulating body of the connector. Too much mechanical stress on a connected cable can impair the connection between the cable and the contact element. In the worst case, the cable can leave the electrical contact element and the electrical connection can be disconnected, which would result in failure of the connector.

Bei Ausführungsformen mit einer zusätzlichen Kabelverschraubung, werden zwar die angeschlossenen Kabel zusätzlich am Steckverbinder mechanisch fixiert und gehalten, diese sind jedoch sehr platzintensiv. Der mechanische Anschluss der Kabel am Steckverbinder benötigt zusätzlichen Bauraum im Anschlussbereich des Steckverbinders. Zudem ist ein umständlicher und aufwändiger Arbeitsschritt bei der Montage des Steckverbinders nötig.In embodiments with an additional cable gland, although the connected cables are mechanically fixed and held in addition to the connector, but these are very space-intensive. The mechanical connection of the cables to the connector requires additional space in the connection area of the connector. In addition, a cumbersome and time-consuming step in the assembly of the connector is necessary.

Aufgabenstellungtask

Die Aufgabe der Erfindung besteht darin einen Steckverbinder oben genannter Art vorzustellen, welcher einen geringen Bauraum einnimmt und zudem eine zusätzliche, mechanische Fixierung angeschlossener Kabel ermöglicht. Dabei soll die Montage einfach, ohne zusätzliche Hilfsmittel und schnell erfolgen können.The object of the invention is to present a connector of the aforementioned type, which occupies a small space and also allows additional, mechanical fixation of connected cables. The assembly should be easy, without additional aids and can be done quickly.

Die Aufgabe wird durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 gelöst.The object is solved by the characterizing features of independent claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Die Erfindung betrifft einen elektrischen Steckverbinder welcher ein isolierendes Steckverbindergehäuse und zumindest ein in dem Steckverbindergehäuse aufgenommenes, elektrisches Kontaktelement aufweist. Das Steckverbindergehäuse bildet eine Steckseite und eine, der Steckseite gegenüberliegende Anschlussseite aus. Im Steckverbindergehäuse ist zudem zumindest eine Kontaktöffnung ausgebildet. Die Kontaktöffnung erstreckt sich von der Steckseite des Steckverbinders durch das Steckverbindergehäuse bis zur Anschlussseite des Steckverbinders. Das Steckverbindergehäuse bildet zugleich den Grundkörper des elektrischen Steckverbinders und vereint die Funktionen von isolierendem Kontaktträger, Gehäuse und Verrastung.The invention relates to an electrical connector which has an insulating connector housing and at least one received in the connector housing, electrical contact element. The connector housing forms a plug-in side and a connection side opposite the plug-in side. In addition, at least one contact opening is formed in the connector housing. The contact opening extends from the plug side of the connector through the connector housing to the terminal side of the connector. The connector housing also forms the main body of the electrical connector and combines the functions of insulating contact carrier, housing and latching.

Die zumindest eine Kontaktöffnung ist dafür vorgesehen ein elektrisches Kontaktelement aufzunehmen. Dabei ist das Kontaktelement in der Kontaktöffnung verrastet und mechanisch fixiert. Eine vorteilhafte Ausführungsform sieht vor, das Kontaktelement über eine Rastnase an einem Vorsprung in der Kontaktöffnung zu verrasten, so dass das Kontaktelement nicht aus der Kontaktöffnung gezogen werden kann.The at least one contact opening is intended to receive an electrical contact element. In this case, the contact element is latched in the contact opening and mechanically fixed. An advantageous embodiment provides to lock the contact element via a latching lug on a projection in the contact opening, so that the contact element can not be pulled out of the contact opening.

Erfindungsgemäß weist das Steckverbindergehäuse auf der Anschlussseite eine Kabelfixierung auf. Die Kabelfixierung ist dafür vorsehen, ein mit einem elektrischen Kontaktelement kontaktiertes Kabel zusätzlich am Steckverbinder zu fixieren. Dabei kann es sich sowohl um ein vollständiges, mehraderiges Kabel handeln, als auch um eine einzelne Ader oder Litze eines Kabels. In beiden Fällen kann die vorliegende Erfindung zur Anwendung kommen. Insofern ist als Kabel sowohl ein Kabel, als auch eine Litze zu verstehen.According to the invention, the connector housing has a cable fixing on the connection side. The cable fixing is intended to additionally fix a contacted with an electrical contact element cable to the connector. This can be either a complete, multi-strand cable, as well as a single wire or strand of a cable. In both cases, the present invention for Application come. In this respect, cable is understood as meaning both a cable and a stranded wire.

Die Kabelfixierung ist aus einem, am Steckverbindergehäuse angeformten, ersten Fixierungselement und einem, mit dem ersten Fixierungselement zusammenwirkenden, zweiten Fixierungselement gebildet. Dabei kann das erste Fixierungselement als separates Bauteil mit dem Steckverbindergehäuse verrastet, verklebt, verschraubt, verschweißt oder anders verbunden sein, oder einstückig mit dem Steckverbindergehäuse ausgeführt sein.The cable fixing is formed from a first fixing element formed on the connector housing and a second fixing element interacting with the first fixing element. In this case, the first fixing element can be locked as a separate component with the connector housing, glued, screwed, welded or otherwise connected, or be designed in one piece with the connector housing.

Das zweite Fixierungselement ist so ausgebildet, dass es mit dem ersten, am Steckverbindergehäuse vorgesehenen Fixierungselement verrastbar ist. Das heißt, dass das zweite Fixierungselement als separates Bauteil geliefert und mit dem ersten Fixierungselement zusammengefügt werden kann. Das zweite Fixierungselement kann jedoch auch bereits am ersten Fixierungselement gehalten sein und durch eine einfache Montage mit diesem verrastet werden.The second fixing element is designed so that it can be latched to the first, provided on the connector housing fixing element. This means that the second fixing element can be supplied as a separate component and joined together with the first fixing element. However, the second fixing element can also already be held on the first fixing element and locked by a simple assembly with this.

Zur Verrastung des ersten Fixierungselements mit dem zweiten Fixierungselement ist eine Führung der Fixierungselemente zueinander ausgebildet. Die Führung ermöglicht es das zweite Fixierungselement linear zum ersten Fixierungselement zu bewegen bis diese zusammen verrasten. Die Führung ist vorteilhaft quer zu der zumindest einen Kontaktöffnung im Steckverbindergehäuse ausgerichtet. Das heißt, dass die Führung ebenfalls quer, also senkrecht zu einer Steckverbinderachse ausgerichtet ist, welche sich von der Steckseite zur Anschlussseite des Steckverbinders erstreckt.For latching the first fixing element with the second fixing element, a guide of the fixing elements to each other is formed. The guide makes it possible to move the second fixing element linearly to the first fixing element until they lock together. The guide is advantageously aligned transversely to the at least one contact opening in the connector housing. This means that the guide is also aligned transversely, ie perpendicular to a connector axis, which extends from the plug side to the connection side of the connector.

Das zweite Fixierungselement weist zumindest zwei erste Schlitze auf. Die ersten Schlitze sind so im Fixierungselement eingeformt, dass sie entlang der Steckverbinderachse und hin zum ersten Fixierungselement offen gestaltet sind. Das heißt, dass die ersten Schlitze von der Anschlussseite hin zur Steckseite offen sind und aus Richtung des ersten Fixierungselements Zugriff gewährt. Die ersten Schlitze sind zwekckmäßig nebeneinander im zweiten Fixierungselement vorgesehen. Sie dienen der Aufnahme von Kabeln, welche in das Steckverbindergehäuse geführt werden.The second fixing element has at least two first slots. The first slots are formed in the fixing element so that they along the connector axis and towards the first fixing element are designed open. This means that the first slots are open from the connection side to the plug-in side and allow access from the direction of the first fixing element. The first slots are provided zwekckmäßig side by side in the second fixing element. They serve to accommodate cables which are guided into the connector housing.

Zur Fixierung von Kabeln in den ersten Schlitzen im zweiten Fixierungselement sind in den ersten Schlitzen zudem zumindest zwei Stege vorgesehen. Die auf zwei gegenüberliegenden Innenseiten der ersten Schlitze angeformten Stege sind in Richtung des ersten Fixierungselements ausgerichtet. Das heißt, dass die Stege zueinander parallel und senkrecht zur Steckverbinderachse ausgerichtet sind. So kann das zweite Fixierelement mit einem ersten Schlitz über ein Kabel greifen, wenn es mit dem ersten Fixierelement verrastet wird.For fixing cables in the first slots in the second fixing element, at least two webs are additionally provided in the first slots. The integrally formed on two opposite inner sides of the first slots webs are aligned in the direction of the first fixing element. This means that the webs are aligned parallel to each other and perpendicular to the connector axis. Thus, the second fixing element can engage with a first slot via a cable when it is locked with the first fixing element.

Das zweite Fixierungselement weist einen zweiten Schlitz zwischen jeweils zwei ersten Schlitzen auf. Der zweite Schlitz ist zur Aufnahme einer Rippe vorgesehen, welche am ersten Fixierungselement angeformt ist. Dabei greift die in Richtung des zweiten Fixierungselements ausgerichtete Rippe bei Zusammenführen der Fixierungselemente in den zweiten Schlitz ein.The second fixing element has a second slot between each two first slots. The second slot is provided for receiving a rib, which is integrally formed on the first fixing element. In this case, the aligned in the direction of the second fixing element rib engages in merging the fixing elements in the second slot.

Durch eine vorteilhafte Relation der Stärke der Rippen und der zweiten Schlitze zueinander, wird so eine besonders vorteilhafte Klemmung von Kabeln in den ersten Schlitzen erzielt. Dafür sind die Rippen etwas breiter als die zweiten Schlitze ausgeführt. Beim Zusammenführen der ersten und zweiten Fixierungselemente werden so die zweiten Schlitze etwas auseinander gedrückt und gleichzeitig die ersten Schlitze zusammen gedrückt. In den ersten Schlitzen gehaltene Kabel werden so noch besser fixiert und gehalten.By an advantageous relation of the strength of the ribs and the second slots to each other, a particularly advantageous clamping of cables in the first slots is achieved. For the ribs are slightly wider than the second slots executed. When merging the first and second fixing elements so the second slots are pressed slightly apart and at the same time pressed together the first slots. In the first slots held cables are fixed and held even better.

Die Erfindung löst so die Aufgabe, einen Steckverbinder vorzustellen, welcher auf sehr kleinem Bauraum eine zusätzliche Kabelfixierung realisiert. Die Montage von Kontaktelementen und Kabeln ist durch ein einfaches Verrasten der zwei Fixierungselemente möglich.The invention thus solves the problem of presenting a connector which realizes an extra cable fixation in a very small space. The assembly of contact elements and cables is possible by a simple locking of the two fixing elements.

Die Figur 2 zeigt eine weitere perspektivische Darstellung des erfindungsgemäßen elektrischen Steckverbinders 1 aus Figur 1. In dieser Darstellung ist der Steckverbinder 1 mit Blick auf den Anschlussseite 5 gezeigt. Auf der Anschlussseite 5 ist das erste Fixierungselement 8 einteilig mit dem Steckverbindergehäuse 2 verbunden.The FIG. 2 shows a further perspective view of the electrical connector 1 according to the invention FIG. 1 , In this illustration, the connector 1 is shown with a view of the connection side 5. On the connection side 5, the first fixing element 8 is integrally connected to the connector housing 2.

Unterhalb des ersten Fixierungselements 8 ist das zweite Fixierungselement 9 angeordnet. Beide Fixierungselemente 8, 9 verfügen seitlich über Führungen 14. Mittels der Führungen 14 wird ein lineares Führen der Fixierungselemente 8, 9 zueinander ermöglicht. Das zweite Fixierungselement 9 kann so auf das erste Fixierungselement 8 geschoben und mit diesem verrastet werden.Below the first fixing element 8, the second fixing element 9 is arranged. Both fixing elements 8, 9 have laterally guides 14. By means of the guides 14 is a linear guiding the fixing elements 8, 9 allows each other. The second fixing element 9 can be pushed onto the first fixing element 8 and locked with this.

Erfindungsgemäß verfügt das zweite Führungselement 9 über mehrere - hier fünf - erste Schlitze 10. Die ersten Schlitze sind so ausgerichtet, dass sie entlang der Steckverbinderachse und hin zum ersten Fixierungselement 8 offen sind. Dies ermöglicht, dass beim Zusammenfügen des ersten Fixierungselements 8 mit dem zweiten Fixierungselement 9 die Kabel 20 in den ersten Schlitzen 10 aufgenommen werden können.According to the invention, the second guide element 9 has several - here five - first slots 10. The first slots are aligned so that they are open along the connector axis and towards the first fixing element 8. This makes it possible for the cables 20 to be received in the first slots 10 when the first fixing element 8 is joined to the second fixing element 9.

Um eine mechanische Fixierung der Kabel 20 in den ersten Schlitzen 10 zu gewähren, sind auf den Innenseiten der ersten Schlitze 10 zusätzlich Stege 11 angeformt. Die Stege 11 sind so ausgelegt, dass sie ein eingeführtes Kabel 10 mechanisch klemmen. Die Stege 11 sind in der Figur 4 noch näher beschrieben.In order to provide a mechanical fixation of the cable 20 in the first slots 10, webs 11 are additionally formed on the inner sides of the first slots 10. The webs 11 are designed to mechanically clamp an inserted cable 10. The webs 11 are in the FIG. 4 described in more detail.

Ein Querschnitt durch einen erfindungsgemäßen, elektrischen Steckverbinder 1 ist in der Figur 3 dargestellt. Im Unterschied zu den Figuren 1 und 2 ist die Kabelfixierung, bestehend aus dem ersten Fixierungselement 8 und dem zweiten Fixierungselement 9 vollständig montiert. Die Führungen 14 der ersten und zweiten Fixierungselemente 8, 9 greifen vollständig ineinander.A cross section through an inventive electrical connector 1 is in the FIG. 3 shown. Unlike the Figures 1 and 2 is the cable fixing, consisting of the first fixing element 8 and the second fixing element 9 completely assembled. The guides 14 of the first and second fixing elements 8, 9 fully engage each other.

Jeder der ersten Schlitze 10 nimmt zwei Kabel 20 übereinander auf. Zwischen jeweils zwei ersten Schlitzen 10 weist das zweite Fixierungselement 9 jeweils einen weiteren, zweiten Schlitz 13 auf. In den zweiten Schlitzen 13 ist jeweils eine Rippe 12 des ersten Fixierungselements 8 aufgenommen. Neben einer zusätzlichen Führung des ersten Fixierungselements 8 und dem zweiten Fixierungselement 9 zueinander, dienen die zweiten Schlitze 13 in Verbindung mit den Rippen 12 zur zusätzlichen Fixierung der Kabel 20, sowie zur Versteifung des zweiten Fixierungselements 9.Each of the first slots 10 receives two cables 20 one above the other. Between each two first slots 10, the second fixing element 9 each have a further, second slot 13. In each case a rib 12 of the first fixing element 8 is received in the second slots 13. In addition to an additional guidance of the first fixing element. 8 and the second fixing element 9 to each other, serve the second slots 13 in conjunction with the ribs 12 for additional fixing of the cable 20, and for stiffening the second fixing element. 9

Die Rippen 12 sind etwas breiter dimensioniert, als die zweiten Schlitze 13. Dadurch werden die zweiten Schlitze 13 beim Zusammenfügen der beiden Fixierungselemente 8, 9 etwas geweitet. Gleichzeitig werden die ersten Schlitze 10 dadurch etwas zusammengepresst. Dies führt wiederum zu einer stärkeren Klemmung der Kabel 20 die in den ersten Schlitzen 10 aufgenommen sind.The ribs 12 are dimensioned slightly wider than the second slots 13. As a result, the second slots 13 are somewhat widened when joining the two fixing elements 8, 9. At the same time, the first slots 10 are slightly compressed thereby. This in turn leads to a stronger clamping of the cables 20 which are received in the first slots 10.

Ein vereinzeltes zweites Fixierungselement 9 ist in der Figur 4 in perspektivischer Darstellung gezeigt. Fünf erste Schlitze 10 sind nebeneinander angeordnet, wobei zwischen jeweils zwei ersten Schlitzen 10 ein zweiter Schlitz 13 vorgesehen ist.An isolated second fixing element 9 is in the FIG. 4 shown in perspective. Five first slots 10 are arranged side by side, wherein between each two first slots 10, a second slot 13 is provided.

Besonders gut sind die Stege 11 erkennbar. Diese sind auf den Innenseiten der ersten Schlitze 10 vorgesehen. In diesem Ausführungsbeispiel sind jeweils drei Stege 11 parallel nebeneinander angeordnet. Die Stege 11 sind senkrecht zur Steckverbinderachse ausgereichtet, so dass beim Zusammenfügen des zweiten Fixierungselements 9 und des ersten Fixierungselements 8 die Kabel 20 entlang der Stege 11 in die ersten Schlitze 10 gleiten können. Durch die Ausrichtung der Stege 11 senkrecht zur Steckverbinderachse können die Kabel 20 jedoch nicht entlang der Steckverbinderachse aus der Kabelfixierung und dem Steckverbinder 1 gezogen werden.Particularly well, the webs 11 are recognizable. These are provided on the insides of the first slots 10. In this embodiment, three webs 11 are arranged parallel to each other. The webs 11 are aligned perpendicular to the connector axis, so that when joining the second fixing element 9 and the first fixing element 8, the cables 20 can slide along the webs 11 in the first slots 10. By aligning the webs 11 perpendicular to the connector axis, however, the cables 20 can not be pulled along the connector axis of the cable fixing and the connector 1.

Die erfindungsgemäße Aufgabe, einen elektrischen Steckverbinder 1 mit einer zusätzlichen Kabelfixierung auszustatten wird so besonders vorteilhaft auf sehr kleinem Bauraum realisiert. Die Montage kann durch einen einfachen Handgriff ohne weiteres Werkzeug getätigt werden.The object of the invention to equip an electrical connector 1 with an additional cable fixation is realized so particularly advantageous in a very small space. The assembly can be made by a simple operation without further tools.
