Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer elektrischen Steckvorrichtung nach der Gattung des Anspruchs 1. Eine derartige Steckvorrichtung ist aus der EP 0 273 999 B1 bekannt.The invention relates to an electrical plug-in device according to the preamble of claim 1. Such a plug-in device is known from EP 0 273 999 B1 known.

Bei einer Steckvorrichtung, die aus zwei zusammenfügbaren Steckverbindern besteht, ist die Kraft, die zum Zusammenfügen oder Trennen der beiden Steckverbinder benötigt wird, abhängig von der Anzahl der in der Steckvorrichtung jeweils paarweise zugeordneten Steckkontaktelementen.In a plug-in device, which consists of two mating connectors, the force that is required to join or disconnect the two connectors, depending on the number of pairs in the plug device associated mating contact elements.

Für eine sichere elektrische Kontaktierung, insbesondere bei Vorliegen hoher Beanspruchungen der Steckvorrichtung z.B. durch Vibration und Temperaturschwankungen, wird eine Mindestkontaktnormalkraft benötigt, mit der der Kontaktbereich eines Buchsenkontakts auf einen messerförmigen Gegenkontakt aufgepresst wird. Somit ist zur Herstellung einer Steckverbindung eine Mindeststeckkraft für jeden einzelnen Kontakt erforderlich.For a secure electrical contact, in particular in the presence of high stresses of the plug-in device, for. due to vibration and temperature fluctuations, a minimum contact normal force is required, with which the contact area of a socket contact is pressed onto a knife-shaped mating contact. Thus, a minimum insertion force for each contact is required to produce a connector.

Insbesondere bei hochpoligen Steckvorrichtungen mit einer großen Zahl von Kontakten resultiert aus der Steckkraft der Einzelkontakte eine Gesamtsteckkraft der Steckverbindung, die für den Anwender nur noch schwer aufzubringen ist.Especially with high-pin plug devices with a large number of contacts resulting from the insertion force of the individual contacts a Gesamtsteckkraft the connector, which is difficult to apply for the user.

Aus der EP 0 273 999 B1 ist bekannt, zur Überwindung der Gesamtsteckkraft der Steckvorrichtung eine Hilfsvorrichtung zu verwenden. Die Hilfsvorrichtung umfasst ein an einem der Steckverbinder gelagertes Handhabungsteil, das einseitig einen Ritzelbereich aufweist, dessen Zähne in einer Zahnstange in Eingriff sind, die bei einem Schwenken des Handhabungsteils in dem einen Steckverbinder verschiebbar ist. An der Zahnstange sind schräg zur Steckrichtung verlaufende Kulissennuten angebracht, die jeweils an einem, zum anderen Steckverbinder weisenden Endbereich offen sind und mit zugeordneten Nockenvorsprüngen am anderen der Steckverbinder in Eingriff gebracht werden können.From the EP 0 273 999 B1 It is known to use an auxiliary device to overcome the Gesamtsteckkraft the plug-in device. The auxiliary device comprises a mounted on one of the connectors handling part having a pinion portion on one side, the teeth of which are engaged in a rack, which in a pivoting of the handling part in the one Connector is slidable. On the rack obliquely to the direction of insertion extending guide grooves are mounted, which are each open at one, the other connector facing end portion and can be brought with associated cam projections on the other of the connector in engagement.

Durch diese Anordnung lassen sich die Gesamtsteckkräfte der Steckvorrichtung zwar reduzieren; jedoch ist durch den erforderlichen baulichen Aufwand die Steckvorrichtung großvolumig und in der Herstellung kostenintensiv.By this arrangement, the total insertion force of the plug-in device can indeed reduce; However, the plug-in device is bulky and costly to manufacture due to the required structural complexity.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße elektrische Steckvorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, dass die zuvor erwähnten Unzulänglichkeiten in zufriedenstellendem Maß vermieden werden.The electrical plug-in device according to the invention with the characterizing features of claim 1 has the advantage that the aforementioned shortcomings are satisfactorily avoided.

Dazu wird zu Beginn des Kopplungsvorgangs der beiden Steckverbinder vor oder mit einer Einführung der Steckkontakte in die Buchsenkontakte durch wenigstens ein Spreizelement die Buchsenkontakte aufgespreizt. Damit lassen sich die Steckkontakte erleichtert in die Buchsenkontakte einführen und die Gesamtsteckkraft der Steckverbindung ist reduziert. Erst während oder im weiteren Verlauf der Einführung der Steckkontakte in die Buchsenkontakte wird die Aufspreizung zurückgeführt, so dass im Kontaktbereich die erforderliche Kontaktnormalkräfte zur Sicherung der elektrischen Verbindungen auftreten. Auf diese Weise lässt sich eine funktionssichere elektrische Steckvorrichtung realisieren, deren Gesamtsteckkraft gering ist und die dabei bei kleinem Volumen fertigungsgünstig herstellbar ist.For this purpose, at the beginning of the coupling process of the two connectors before or with an introduction of the plug contacts in the socket contacts by at least one expansion element spreads the socket contacts. This makes it easier to insert the plug contacts in the socket contacts and the total insertion force of the connector is reduced. Only during or in the course of the introduction of the plug contacts in the socket contacts, the spreading is returned, so that occur in the contact area, the required contact normal forces to secure the electrical connections. In this way, a functionally reliable electrical plug-in device can be realized whose total insertion force is low and which can be produced at low production volume.

In den Unteransprüchen sind vorteilhafte Maßnahmen für die Realisierung der Erfindung angegeben.In the dependent claims advantageous measures for the realization of the invention are given.

Durch die Lagezuordnung des Buchsenkontakts zu einer Aufnahmekammer eines Kontaktträgers lässt sich der Buchsenkontakt gezielt kontaktieren.Due to the position assignment of the socket contact to a receiving chamber of a contact carrier, the socket contact can specifically contact.

Mit der Ausbildung eines Spreizelements in der Aufnahmekammer wird der Buchsenkontakt schon im Laufe der Einführung in die Aufnahmekammer selbstständig, ohne einen separaten Aurbeitsschritt, aufgespreizt.With the formation of a spreading element in the receiving chamber of the socket contact already in the course of the introduction into the receiving chamber automatically, without a separate Aurbeitsschritt, spread.

Durch die Längsverschieblichkeit des Buchsenkontakts in der Aufnahmekammer lässt sich die Kopplung mit dem in der Aufnahmekammer angebrachten Spreizelement axial verändern.Due to the longitudinal displaceability of the socket contact in the receiving chamber, the coupling with the spreading element mounted in the receiving chamber can be changed axially.

Mittels einer in dem Buchsenkontakt angebrachten Anlauffläche ist ein Element für eine Axialverschiebung des Buchsenkontakts durch einen eingeführten Steckkontakt gegeben.By means of a contact surface mounted in the socket contact is given an element for an axial displacement of the socket contact by an inserted plug contact.

Durch eine Axialverschiebung des Buchsenkontakts in der Aufnahmekammer können die erforderliche Kontaktkräfte zur Sicherung der elektrischen Verbindungen wirksam werden.By an axial displacement of the socket contact in the receiving chamber, the required contact forces to secure the electrical connections can be effective.

Mit dem Einführen eines der Aufnahmekammer zugeführten Spreizelements in den dort platzierten Buchsenkontakt kann ein bereits in der Aufnahmekammer befindlicher Buchsenkontakt aufgespreizt werden und diese Aufspreizung mit der nachfolgenden Einführung des Steckkontakts in die Aufnahmekammer rückgeführt werden.With the introduction of a receiving chamber supplied spreading element in the socket contact placed there, a already in the receiving chamber befindlicher socket contact can be spread and this spread with the subsequent introduction of the plug contact are returned to the receiving chamber.

Mittels eines in der Aufnahmekammer angeordneten rückfederungsfähigen Rastarms lässt sich eine Axialverschiebung des Buchsenkontakts in der Aufnahmekammer begrenzen und so eine Sicherung der Überdeckung des Buchsenkontakts mit dem Steckkontakt erzielen.By means arranged in the receiving chamber spring-back latching arm can be an axial displacement of the socket contact in the receiving chamber limit and so achieve a backup of the coverage of the socket contact with the plug contact.

Durch die Ausgestaltung einer Rastkontur an dem Spreizelement kann ein vorbestimmter Aufspreizweg der Kontaktlamellen in fertigungstechnisch vorteilhafter Weise kraftgesteuert vorgenommen werden.Due to the configuration of a latching contour on the expansion element, a predetermined Aufspreizweg the contact blades can be made force-controlled in production technology advantageous manner.

Each in a sectional view, the first embodiment in the FIG. 1 and the second embodiment in the FIG. 2 shown. Each of these figures shows in a series representation with joined sub-figures individual phases in the assembly of a first connector with a female contact and a subsequent insertion of a plug contact in the socket contact for closing the electrical connector.

Beschreibung der AusführungsbeispieleDescription of the embodiments

In den Figuren sind gleiche Bauteile und Bauteile mit gleicher Funktion mit den gleichen Bezugszeichen gekennzeichnet.In the figures, the same components and components with the same function with the same reference numerals.

Eine elektrische Steckvorrichtung 11, entsprechend den Figuren 1, 2, umfaßt einen ersten Steckverbinder 12, der Buchsenkontakte 13 aufweist und einen zweiten Steckverbinder 14, der Steckkontakte 16 enthält, die entlang einer Steckrichtung 17 jeweils in den zugeordneten Buchsenkontakt 13 einführbar sind.An electrical connector 11, according to the FIGS. 1 . 2 , comprises a first connector 12, the socket contacts 13 and a second connector 14, the plug contacts 16 includes, which are insertable along a plug-in direction 17 in the associated socket contact 13.

In einem Kontaktträger 18 des ersten Steckverbinders 12 sind entsprechend der Polzahl der Steckvorrichtung 11 in Reihen angeordnete Aufnahmekammern 19 für die Buchsenkontakte 13 angeordnet.In a contact carrier 18 of the first connector 12 11 arranged in rows receiving chambers 19 are arranged for the socket contacts 13 corresponding to the number of poles of the plug-in device.

Der Buchsenkontakt 13 weist zum Anschluß eines elektrischen Leiters 21 einen Anschlußabschnitt 22, einen daran anschließenden Verriegelungsabschnitt 23 zur Lagefixierung des Buchenkontakts 13 in der Aufnahmekammer 19 und einen darauf folgenden Kontaktabschnitt 24 zum Kontaktieren mit einem zugeordnetenSteckkontakt 16 auf. Der Verriegelungsabschnitt 23 nimmt gegenüber dem Anschlußabschnitt 22 und dem Kontaktabschnitt 24 eine verminderte Querschnittsfläche ein.The socket contact 13 has for connection of an electrical conductor 21 a connecting portion 22, an adjoining locking portion 23 for fixing the position of the Buchungskontakts 13 in the receiving chamber 19 and a subsequent contact portion 24 for contacting with an associated male contact 16. The locking portion 23 occupies a reduced cross-sectional area with respect to the terminal portion 22 and the contact portion 24.

In der Figur 1 ist bei einem ersten Ausführungsbeispiel in einer Reihendarstellung mit aneinandergefügten Teilfiguren die Bestückung einer Aufnahmekammer 19 durch einen Buchsenkontakt 13 im Bewegungsablauf in einer der Steckrichtung 17 entgegengerichteten Fügerichtung und die Zuführung eines der Steckkontakte 16 in Steckrichtung 17 schrittweise fortfahrend gezeigt.In the FIG. 1 is in a first embodiment in a series representation with joined sub-figures, the assembly of a receiving chamber 19 by a socket contact 13 in the sequence of movement in a direction of insertion 17 opposing joining direction and the supply of one of the plug contacts 16 in the insertion direction 17 gradually shown progressively.

In der ersten Teilfigur links außen ist der Buchsenkontakt 13 noch außerhalb der Aufnahmekammer 19 angeordnet. Dabei ist der Kontaktabschnitt 24 des Buchsenkontakts mit einem außenliegenden kastenförmigen Grundkörper 26 einer Zuführöffnung 27 der Aufnahmekammer 19 fluchtend zur Steckrichtung 17 zugewandt.In the first part figure left outside of the female contact 13 is still arranged outside the receiving chamber 19. In this case, the contact portion 24 of the socket contact with an outer box-shaped base body 26 of a feed opening 27 of the receiving chamber 19 facing the direction of insertion 17 is aligned.

In der zweiten Teilfigur von links ist der Grundkörper 26 bereits durch die Zuführöffnung 27 hindurchgetreten und befindet sich größtenteils in einem Dichtabschnitt 28 der Aufnahmekammer 19. Eine freiliegende Stirnseite 29 des Grundkörpers befindet sich bereits in einem, an den Dichtabschnitt 28 angrenzenden Zentriertrichter 31, der in der vorgehenden Teilfigur unverdeckt dargestellt und hier bezeichnet ist.In the second subfigure from the left, the main body 26 has already passed through the feed opening 27 and is located for the most part in a sealing section 28 of the receiving chamber 19. An exposed end face 29 of the main body is already located in a centering funnel 31 adjacent to the sealing section 28 the preceding part of the figure uncovered and referred to here.

In der dritten Teilfigur von links ist der Grundkörper 26 vollständig in einen, dem Zentriertrichter 31 nachfolgenden Lagerabschnitt 32 der Aufnahmekammer 19 eingetaucht. Der Lagerabschnitt 32 endet stirnseitig an einer Wand 33, die von einer Einstecköffnung 34 durchbrochen ist, die sich gegen die Steckrichtung 17 trichterförmig erweitert. Ein seitlich in dem Lagerabschnitt 32 fest angeordneter rückfederungsfähiger Rastarm 36 ist durch den Grundkörper 26 aus seiner Ruhelage, entsprechend den ersten beiden Teilfiguren, vorgespannt ausgelenkt.In the third subfigure from the left, the main body 26 is completely immersed in a bearing section 32, following the centering funnel 31, of the receiving chamber 19. The bearing portion 32 terminates at the end on a wall 33 which is pierced by an insertion opening 34, which widens in a funnel shape against the insertion direction 17. A laterally in the bearing portion 32 fixedly arranged spring-back locking arm 36 is biased by the base body 26 from its rest position, corresponding to the first two sub-figures, biased.

Über der Einstecköffnung ist auf der Wand 33 ein in den Lagerabschnitt 32 ragendes keilförmiges Spreizelement 37 angebracht. Dieses ist axial, in Flucht zur Steckrichtung 17, für einen, im nachfolgenden Verlauf beschriebenen Durchtritt eines Steckkontakts 16 durchbrochen.About the insertion opening 33 projecting into the bearing portion 32 wedge-shaped expansion element 37 is mounted on the wall. This is axially, in alignment with the plug-in direction 17, broken for a described in the following course passage of a plug-in contact 16.

In der 4. Teilfigur von links ist das Spreizelement 37 soweit in den Kontaktabschnitt 24 eingedrungen, dass es zwischen zwei ausfederungsfähigen Kontaktlamellen 38 gelangt ist und diese auseinanderspreizt. Ferner ist der Rastarm 36 in seine Ruhelage zurückgekehrt und blockiert mit einer hinter dem Grundkörper 26 liegenden Rastnase 39 ein mögliches Ausschieben des Buchsenkontakts 13 aus der Aufnahmekammer 19.In the 4th subfigure from the left, the spreader element 37 has penetrated into the contact section 24 so far that it can be rebated between two Contact blades 38 has arrived and this spread apart. Further, the latch arm 36 has returned to its rest position and blocked with a lying behind the main body 26 locking lug 39 a possible pushing out of the socket contact 13 from the receiving chamber 19th

In der 5. Teilfigur von links ist die Zuführbewegung des Buchsenkontakts 13 in die Aufnahmekammer 19 durch ein Aufstoßen der Stirnseite 29 an der Wand 33 abgeschlossen.In the 5th sub-figure from the left, the feed movement of the socket contact 13 is closed in the receiving chamber 19 by a regurgitation of the end face 29 on the wall 33.

In der 6. Teilfigur von links wird ein auf die Einstecköffnung 34 gerichteter Steckkontakt 16 dem Buchsenkontakt 13 in der Aufnahmekammer 19 zugeführt.In the 6th subfigure from the left, a plug-in contact 34 directed towards the insertion opening 16 is fed to the socket contact 13 in the receiving chamber 19.

In der 7. Teilfigur von links ist der Steckkontakt 16 über eine Teillänge durch den Zentriertrichter 31 geführt und ragt endseitig in den aufgespreizten Bereich der Kontaktlamellen 38 hinein.In the 7th part figure from the left of the plug-in contact 16 is guided over a partial length by the centering funnel 31 and protrudes end into the spread area of the contact blades 38 inside.

Nach einer weitergeführten Zuführbewegung des Steckkontakts 16 entsprechend der 8. Teilfigur von links ist der Steckkontakt 16 endseitig in Anlage an eine fest in dem Kontaktabschnitt 24 des Buchsenkontaktes 13 angebrachte, lotrecht zur Steckrichtung ausgerichtete Anlauffläche 41 gelangt und der Buchsenkontakt 13 wird im weiteren Verlauf der Zuführbewegung in der Aufnahmekammer 19 axial in Steckrichtung 17 verschoben. Damit gelangt das Spreizelement 37 in einen Bereich, in dem der Abstand der Kontaktlamellen 38 sich trichterförmig erweitert, so dass der Einfluß des Spreizelements 37 auf die Kontaktlamellen 38 endet. Dadurch schnappen die zuvor aufgehaltenen Kontaktlamellen 38 zurück und der Kontakt zwischen den Kontaktlamellen 38 des Buchsenkontakts 13 und dem Steckkontakt 16 erhält die gewünschte hohe Kontaktnormalkraft.After a continued feed movement of the plug contact 16 according to the 8th subfigure from the left of the plug contact 16 end is in contact with a fixed in the contact portion 24 of the female contact 13 attached, aligned perpendicular to the insertion direction stop face 41 and the female contact 13 is in the further course of the feed moved axially in the receiving direction 19 in the receiving chamber 17. Thus, the expansion element 37 reaches a region in which the distance of the contact blades 38 widens in a funnel shape, so that the influence of the expansion element 37 ends on the contact blades 38. As a result, the previously held contact blades 38 snap back and the contact between the contact blades 38 of the socket contact 13 and the plug contact 16 receives the desired high contact normal force.

Die rückwärtige Axialverschiebung des Buchsenkontakts 13 in der Aufnahmekammer 19 endet entsprechend der 9. Teilfigur von links mit einem Anschlag einer Rückseite 42 des Kontaktabschnitts 24 an der Rastnase 39.The rearward axial displacement of the socket contact 13 in the receiving chamber 19 ends in accordance with the 9th subfigure from the left with a stop of a rear side 42 of the contact portion 24 on the detent 39th

In der Figur 2 ist bei einem zweiten Ausführungsbeispiel in einer Reihendarstellung mit aneinandergefügten Teilfiguren die Bestückung einer Aufnahmekammer 19 durch einen Buchsenkontakt 13 im Bewegungsablauf in der der Steckrichtung 17 entgegengerichteten Fügerichtung und die Zuführung eines Steckkontaktes 16 in Steckrichtung 17 schrittweise fortfahrend gezeigt.In the FIG. 2 is in a second embodiment in a series representation with joined sub-figures, the placement of a receiving chamber 19 by a female contact 13 in the movement in the joining direction 17 opposing joining direction and the supply of a plug-in contact 16 in the insertion direction 17 shown gradually progressing.

Abweichend von dem ersten Ausführungsbeispiel ist weder in dem Lagerabschnitt 32 der Aufnahmekammer 19 ein ortsfestes Spreizelement 37, noch in dem Kontaktabschnitt 24 des Buchsenkontakts 13 eine Anlauffläche 41 angebracht. Vielmehr wird vor Einführung des Steckkontakts 16 in den Buchsenkontakt 13 ein hohlkammerförmiges Spreizelement 37, dessen Ausformung einen späteren Durchtritt des Steckkontakts 16 erlaubt, in Steckrichtung 17 durch die Einstecköffnung 34 der Aufnahmekammer 19 über eine Teillänge in den Lagerabschnitt 32 eingebracht und in nicht näher dargestellter Weise in einer Vorraststellung fixiert.Notwithstanding the first embodiment, neither in the bearing portion 32 of the receiving chamber 19, a stationary expansion element 37, still in the contact portion 24 of the female contact 13, a contact surface 41 is attached. Rather, before introduction of the plug-in contact 16 in the socket contact 13, a hollow-chambered expansion element 37 whose shape allows a later passage of the plug contact 16, introduced in the insertion direction 17 through the insertion opening 34 of the receiving chamber 19 over a partial length in the bearing portion 32 and in a manner not shown fixed in a pre-locked position.

Danach erfolgt eine Einführung des Buchsenkontaktes 13 in die Aufnahmekammer 19, wie zu den ersten fünf Teilfiguren der Figur 1 beschrieben und in den ersten vier Teilfiguren der Figur 2 dargestellt. Damit sind die Kontaktlamellen 38, vorbereitet für die Einführung des jeweiligen Steckkontaktes 16, durch das Auflaufen der Kontaktlamellen 38 auf das Spreizelement 37 aufgespreizt.Thereafter, an introduction of the female contact 13 in the receiving chamber 19, as to the first five sub-figures of FIG. 1 described and in the first four subfigures of FIG. 2 shown. Thus, the contact blades 38, prepared for the introduction of the respective plug contact 16, spread by the emergence of the contact blades 38 on the spreader 37.

Entsprechend der Figur 2 mit den Teilfiguren 5-8 von links wird der Steckkontakt 16, der aus einer Leiste 43 des zweiten Steckverbinders 14 herausragt, fortschreitend in den Lagerabschnitt 32 des Buchsenkontaktes 13 in Steckrichtung 17 eingeführt. Dabei gelangt das freie Ende des stiftförmigen Steckkontakts 16 durch das Spreizelement 37 hindurch zwischen die aufgespreizten Kontaktlamellen 38.According to the FIG. 2 with the subfigures 5-8 from the left of the plug contact 16, which protrudes from a bar 43 of the second connector 14, progressively inserted into the bearing portion 32 of the female contact 13 in the insertion direction 17. In this case, the free end of the pin-shaped plug contact 16 passes through the spreader 37 through between the spread contact blades 38th

Danach erfasst die Leiste 43 eine von einer Außenseite der Wand 33 in der Vorraststellung des Spreizelements 37 distanzierte Bodenplatte 44, auf der das Spreizelement 37 lotrecht hervorstehend gelagert ist und führt diese Bodenplatte 44 bis zu einer Endstellung beim Anschlag an die Außenseite der Wand 33 mit.Thereafter, the bar 43 detects a distance from an outer side of the wall 33 in the pre-locking position of the spreader 37 bottom plate 44 on which the spreader 37 is mounted perpendicular protruding and leads this bottom plate 44 to an end position when attacking the outside of the wall 33 with.

Durch die Verlagerung der Bodenplatte 44 wird auch das darauf befindliche Spreizelement 37 mitbewegt und es gelangt dabei in den Bereich, in dem sich der Abstand der Kontaktlamellen 38 trichterförmig erweitert, so dass der Einfluß des Spreizelements 37 auf die Kontaktlamellen 38 endet. Dadurch schnappen die zuvor aufgespreizten Kontaktlamellen 38 zurück und der Kontakt zwischen den Kontaktlamellen 38 des Buchsenkontakts 13 und dem Steckkontakt 16 erhält die gewünschte hohe Kontaktnormalkraft.By the displacement of the bottom plate 44 and the spreading element 37 located thereon is also moved and it passes into the area in which the distance of the contact blades 38 widens funnel-shaped, so that the influence of the expansion element 37 ends on the contact blades 38. As a result, the previously spread contact blades 38 snap back and the contact between the contact blades 38 of the socket contact 13 and the plug contact 16 receives the desired high contact normal force.

Der Rastarm 36 sichert mit einer Rastnase 39 bei diesem Bewegungsablauf auch hier, wie beim 1. Ausführungselement, ein Ausschieben des Kontaktabschnitts 24 des Buchsenkontaktes 13 entgegen der Fügerichtung aus dem Lagerabschnitt 32.The locking arm 36 secures with a locking lug 39 in this motion sequence here, as in the first embodiment, a pushing out of the contact portion 24 of the socket contact 13 against the joining direction of the bearing portion 32nd

Mit der Ausgestaltung der elektrischen Steckverbindung entsprechend den beiden Ausführungsbeispielen ist es möglich, die Steckkraft und die Kontaktnormalkraft voneinander unabhängig auszubilden in dem Sinne, dass durch die aufgespreizten Kontaktlamellen 38 die Steckkraft gering ausfällt und durch die anschließende Verlagerung des Spreizelements 37 in eine Nichteingriffslage eine gewünschte hohe Kontaktnormalkraft zwischen den Kontaktlamellen 38 und dem Steckkontakt 16 erlangt wird.With the configuration of the electrical connector according to the two embodiments, it is possible to form the insertion force and the contact normal force independently of each other in the sense that due to the spread contact blades 38, the insertion force low and by the subsequent displacement of the expansion element 37 in a disengaged position a desired high Contact normal force between the contact blades 38 and the plug contact 16 is obtained.
