Description

Die Erfindung betrifft eine Anschlusseinrichtung für elektrische Litzenleiter in einem Steckergehäuse nach dem Oberbegriff des Anspruchs 1.The invention relates to a connection device for electrical stranded conductors in a connector housing according to the preamble of claim 1.

Eine derartige Abschlusseinrichtung wird speziell bei elektrischen Leitern benötigt, die als Litzenleitern ausgebildet sind.Such termination device is required especially for electrical conductors, which are designed as stranded conductors.

Die DE 101 43 008 A1 zeigt eine Anschlusseinrichtung für elektrische Litzenleiter in einem elektrischen Steckergehäuse mit in separaten Kammern in Reihen und Spalten angeordneten Stift- und/oder Buchsenkontakten.Die Kontaktierung der Litzenleiter erfolgt hier über einen so genannten Kontaktspieß.The DE 101 43 008 A1 shows a connection device for electrical stranded wire in an electrical connector housing with arranged in separate chambers in rows and columns pin and / or socket contacts. The contacting of the stranded conductor takes place here via a so-called contact spike.

Aus der DE 101 45 324 C1 ist ein elektrisches Anschlusselement zur Kontaktierung von Litzenleitern bekannt, dessen Anschlussende eine sägezahnähnliche Struktur aufweist, auf die eine mittels eines Keiles aufgeweitete, federnde Hülse aufschiebbar ist.From the DE 101 45 324 C1 an electrical connection element for contacting stranded conductors is known, whose terminal end has a sawtooth-like structure, on which a widened by means of a wedge, resilient sleeve can be pushed.

Nachteilig wirkte sich dabei die Anzahl der zur Funktion erforderlichen Einzelteile aus, die mit der erfindungsgemäßen Anmeldung wesentlich reduziert wurde.A disadvantage was the number of items required for the function, which was substantially reduced with the application according to the invention.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Anschlusseinrichtung der eingangs genannten Art dahingehend auszubilden, dass der Anschluss von Litzenleitern mit wenigen und einfachen Bauteilen werkzeuglos erfolgt, wobei ein möglichst großer Bereich bezüglich der zu kontaktierenden Drahtquerschnitte erfasst wird.The invention is therefore based on the object to form a connection device of the type mentioned in that the connection of stranded conductors with few and simple components without tools, wherein the largest possible area is detected with respect to the wire cross sections to be contacted.

Diese Aufgabe wird durch die Kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is solved by the characterizing features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 - 7 angegeben.Advantageous embodiments of the invention are specified in claims 2-7.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass mit diesem Steckergehäuse ein für Litzenleiter werkzeugloses Anschlusssystem zur Verfügung steht, bei dem die Litzenleiter mittels einer federnden Hülse auf den Anschlussbereichen als Stifte und Buchsen ausgebildeter elektrischer Steckkontakte fixierbar sind.
Dabei ist vorgesehen einen Querschnittsbereich von 0,35 - 1,5 mm2 für die Litzenleiter mittel einer montagefreundlichen Klemmvorrichtung abzudecken. Aufgrund eines identischen Rastermaßes mit ähnlichen Steckergehäusen, jedoch anderen Anschlussarten, wie z. B. mit Schraubanschlüssen, ist ein problemloser Austausch möglich.
Dazu sind in dem Steckergehäuse eine Anzahl von Kammern in Reihen und Spalten angeordnet, in denen jeweils eine Klemmvorrichtung für einen Litzenleiter vorgesehen ist.
Die Klemmvorrichtung wird als Anschlusseinrichtung für elektrische Litzenleiter aus einem axial verschiebbaren Schlittenelement gebildet, das zusammen mit einer Klemmhülse auf den Anschlussbereich eines als Stift oder Buchse ausgebildeten elektrischen Kontaktelementes aufschiebbar ist. Dabei ist speziell für Litzenleiter Voraussetzung, dass deren Zuführung in einen Kontaktierungsbereich kraftlos erfolgt, um ein Verdrehen oder Verbie-gen einzelner Kupferadern bis zum Erreichen eines Anschlagpunktes möglichst zu verhindern.The advantages achieved by the invention are, in particular, that with this connector housing for a cordless tool-free connection system is available, in which the stranded conductors by means of a resilient sleeve on the connection areas as pins and sockets trained electrical plug contacts can be fixed.
It is envisaged to cover a cross-sectional area of 0.35 - 1.5 mm 2 for the stranded conductor means of a mounting-friendly clamping device. Due to an identical pitch with similar connector housings, but other types of connection, such. B. with screw, a problem-free replacement is possible.
For this purpose, a number of chambers in rows and columns are arranged in the connector housing, in each of which a clamping device is provided for a stranded conductor.
The clamping device is formed as a connection device for electrical stranded wire from an axially displaceable slide element, which is pushed together with a clamping sleeve on the connection region of a designed as a pin or socket electrical contact element. It is a prerequisite for stranded conductors in particular that their supply into a contacting area is powerless, to a twisting or bending conditions individual copper cores as far as possible to prevent reaching an anchor point.

Das bedeutet, dass während des "Montagezustandes" die Zuführung der Litzenleiter in den Anschlussbereich mit dem Kontaktelement, stets bis zum Anschlagpunkt der Litzen an das Kontaktelement durchgängig offen gestaltet sein muss.This means that during the "mounting state" the supply of the stranded conductors in the connection region with the contact element, must always be designed to be open continuously up to the attachment point of the strands to the contact element.

Dabei wird bei der Montage der abisolierte Teil eines Litzenleiters in eine durch das Schlittenelement hindurchführende Bohrung einschließlich einer am Schlitten fixierten Klemmhülse geführt.In this case, during assembly, the stripped part of a stranded conductor is guided into a bore passing through the carriage element, including a clamping sleeve fixed to the carriage.

Dann wird das Schlittenelement in Steckrichtung des Litzenleiters axial in das Steckergehäuse hinein verschoben.Then, the carriage member is axially displaced in the insertion direction of the stranded conductor into the connector housing.

Dabei ist von Vorteil, dass an den beiden nach außen weisenden Eckbereichen der Schlittenelemente in Schieberichtung angeformte Wulste vorgesehen sind, die aufgrund eines gewissen Übermaßes gegenüber der sie aufnehmenden Kammer, ein unbeabsichtigtes Abgleiten eines Schlittenelementes in Richtung eines Kontaktelementes verhindern.It is advantageous that are provided on the two outwardly facing corner regions of the carriage elements in the sliding direction formed beads, which prevent due to a certain excess over the receiving chamber, an inadvertent sliding of a carriage element in the direction of a contact element.

Mit zunehmender Endstellung des Schlittenelementes wird die federnd ausgebildete Klemmhülse über den vorzugsweise kegelförmig ausgebildeten Kontaktierungs- oder Anschlussbereich der Stift- oder Buchsenkontakte mit dem ihn umgebenden Litzenleiter geschoben.With increasing end position of the carriage member, the resiliently formed clamping sleeve is pushed over the preferably conically shaped Kontaktierungs- or connection area of the pin or socket contacts with the surrounding stranded conductor.

Weiterhin kann der Anschlussbereich pyramiden- bis polygon- wie auch pfeilförmig mit mindestens einer Klemmschulter ausgebildet sein.Furthermore, the connection region can be designed in the shape of a pyramid, polygon or arrow with at least one clamping shoulder.

Dabei gewährleistet die vorteilhaft mit einem mäanderförmigen, durchgehenden Längsschlitz versehene Klemmhülse eine stets der Anzahl und Größe der Litzen angepasste, einschnürende Kraft auf eine durch die Basis des Kegels ausgebildete Klemmschulter am Anschlussbereich der Stift- oder Buchsenkontakte.The advantageously provided with a meandering, continuous longitudinal slot clamping sleeve ensures a constantly adapted to the number and size of the strands, constricting force on a formed by the base of the cone clamping shoulder at the connection area of the pin or socket contacts.

Mit Einsatz eines schmalen, flachen Gegenstandes, z. B. auch einem Schraubendreher, in einen dazu vorgesehenen Schräge an der Außenseite einer jeden Kammer, die in eine Ausnehmung im Schlittenelement hineinreicht, kann jedes Schlittenelement wieder aus der jeweiligen Kammer herausgehebelt werden, womit der Litzenleiter auch wieder freigegeben wird.With the use of a narrow, flat object, z. As well as a screwdriver, in a slant provided on the outside of each chamber, which extends into a recess in the carriage element, each slide member can be levered out again from the respective chamber, whereby the stranded conductor is also released again.

In der Fig.1 ist eine Steckerhälfte 1 bestehend aus einem Gehäuse 10 mit darin angeordneten Stiftkontakten 50 in einer perspektivischen und geschnittenen Darstellung gezeigt.In the Fig.1 is a connector half 1 consisting of a housing 10 with pin contacts 50 disposed therein shown in a perspective and sectional view.

Dabei weist das Gehäuse 10 einen kragenförmigen Steckbereich 4 auf, in den die Stiftkontakte 50 mit ihrer Steckseite 51 hineinragen sowie einen Anschlussbereich 5, der zum Anschluss von Litzenleitern vorgesehen ist.In this case, the housing 10 has a collar-shaped plug-in region 4 into which the pin contacts 50 protrude with their plug side 51 and a connection region 5, which is provided for the connection of stranded conductors.

Der Anschlussbereich 5 weist eine Anzahl von einzelnen Kammern 11 auf, in denen in Reihen und Spalten nebeneinander axial verschiebbare Schlittenelemente 20 angeordnet sind.The connection region 5 has a number of individual chambers 11, in which slide elements 20, which are axially displaceable in rows and columns next to each other, are arranged.

In der gleichen Anordnung sind die Stiftkontakte 50 in dem Gehäuse 10 positioniert.In the same arrangement, the pin contacts 50 are positioned in the housing 10.

Dazu weisen die Stiftkontakte 50 jeweils einen Bund 57 auf, mit dem sie in einem entsprechend geformten Haltebereich 13 etwa mittig des Gehäuses 10 unterhalb der Kammern 11 eingefügt und mittels Rastelementen 15 verrastet sind.For this purpose, the pin contacts 50 each have a collar 57, with which they are inserted in a correspondingly shaped holding portion 13 approximately centrally of the housing 10 below the chambers 11 and latched by means of locking elements 15.

Dabei ragt die stiftförmige Steckseite 51 der Stiftkontakte durch Öffnungen 12 unterhalb des Haltebereiches 13 in den Steckbereich 4 hinein, während der Anschlussbereich 52 mit einer Kegelspitze 53 und einer Klemmschulter 54 ausgebildet, in die Kammer 11 hineinreicht.In this case, the pin-shaped plug-in side 51 of the pin contacts projects through openings 12 below the holding region 13 into the plug-in region 4, while the connection region 52 with a cone tip 53 and a clamping shoulder 54 extends into the chamber 11.

In jeder der Kammern 11 ist ein axial verschiebbares Schlittenelement 20 eingefügt, wobei das Schlittenelement hier in einer "Montagestellung" zum Teil aus dem Gehäuse 10 herausragend gezeigt ist.In each of the chambers 11, an axially displaceable slide member 20 is inserted, wherein the slide member is shown here in a "mounting position" partially protruding from the housing 10.

Das Schlittenelement weist prinzipiell einen Rundkörper 22 auf, an dem außen eine quadratische Form bildend, vier Eckbereiche 23 angeformt sind, von denen zwei nebeneinander liegende Eckbereiche in eine Schlittenführung 21 übergehen.In principle, the carriage element has a round body 22 on which a square shape is formed on the outside, four corner areas 23 are formed, two of which adjoin adjacent corner areas in a carriage guide 21.

An dieser Seite sind die beiden außenliegenden Eckbereiche 23 bereichsweise mit einem in Schieberichtung angeformten Wulst 33 versehen, der aufgrund eines leichten Aufmaßes gegenüber der aufnehmenden Kammer 11, ein unbeabsichtigtes Absinken des Schlittenelementes 20, bei nicht montierten Litzenleitern, verhindert.On this side, the two outer corner regions 23 are provided in regions with a molded bead 33 in the sliding direction, which prevents due to a slight oversize relative to the receiving chamber 11, an unintentional lowering of the carriage member 20, not mounted stranded conductors.

Weiterhin ist an der Schlittenführung 21 ein Anschlag 29 vorgesehen, der beim Verschieben des Schlittenelementes an den für die Arretierung des Stiftkontaktes 50 vorgesehenen Anschlag 16 des außenliegenden Rastelementes 15 anschlägt.Furthermore, a stop 29 is provided on the carriage guide 21, which abuts when moving the carriage member to the provided for the locking of the pin contact 50 stop 16 of the outer latching element 15.

Ein Herausfallen des Schlittenelementes 20 aus einer der Kammern 1 1 des Gehäuses wird mittels gegenseitig verrastender Rastkanten 18, 28 an der nach außen weisenden Seite der Schlittenführung 21 und an der entsprechenden Seite der Kammern 11 verhindert.Falling out of the carriage member 20 from one of the chambers 1 1 of the housing is prevented by means of mutually latching locking edges 18, 28 on the outwardly facing side of the carriage guide 21 and on the corresponding side of the chambers 11.

Dazu ist an der nach außen weisenden Schlittenführung 21 eine erhabene, schmale Führungsschiene 32 angeformt, die in eine Nut 19 an der Gehäusewand eingreift.For this purpose, a raised, narrow guide rail 32 is integrally formed on the outwardly facing carriage guide 21, which engages in a groove 19 on the housing wall.

Im Zentrum des Schlittenelementes 20 ist eine Durchgangsbohrung 24 mit einem sich trichterförmig verengenden Ausgang 25 vorgesehen.In the center of the carriage member 20, a through hole 24 is provided with a funnel-shaped narrowing exit 25.

Unterhalb des trichterförmigen Ausganges 25 ist eine Klemmhülse 40 angeordnet, und zwar so, dass die Klemmhülse in einer ihrem Durchmesser angepassten, gabelförmigen Halterung 26 einsetzbar ist und gleichzeitig mittels eines rechtwinklig von der Klemmhülse abgekanteter Halteringes 42 in einem oberhalb der Halterung vorgesehen Schlitz 27 des Schlittenelementes fixierbar ist.Below the funnel-shaped outlet 25, a clamping sleeve 40 is arranged, in such a way that the clamping sleeve is adapted to be used in a diameter-adapted, fork-shaped holder 26 and simultaneously a right angle of the clamping sleeve bent retaining ring 42 in a slot 27 provided above the holder of the carriage member is fixable.

Die eigentliche Anschlusseinrichtung wird demnach aus dem Schlittenelement 20, der Klemmhülse 40 und dem hier kegelförmigen Anschlussbereich 52 des Stiftkontaktes 50 gebildet.The actual connection device is accordingly formed from the slide element 20, the clamping sleeve 40 and the here conical connection region 52 of the pin contact 50.

Für die Montage dieser Anschlusseinrichtung ist zunächst der Stiftkontakt 50 in den Haltebereich 13 des Gehäuses 10 einzusetzen und mittels der Rastelemente 15 zu fixieren. Anschließend ist die Klemmhülse 40 mit dem Schlittenelement 20 zu verbinden und zusammen in eine der Kammern 11 einzuschieben, bis die Rastkanten 18 und 28 von Gehäuse und Schlittenelement aneinander liegen.For the installation of this connection device, the pin contact 50 is first to be inserted into the holding region 13 of the housing 10 and fixed by means of the latching elements 15. Subsequently, the clamping sleeve 40 is to be connected to the carriage member 20 and to push together into one of the chambers 11 until the locking edges 18 and 28 of the housing and carriage member are adjacent to each other.

Diese Position ― in der das Schlittenelement 20 noch aus dem Gehäuse 10 herausragt - stellt die "Bestückungsposition" dar, in der ein abisolierter Litzenleiter 8 in die zentral im Schlittenelement 20 eingeformte Durchgangsbohrung 24 bis in die darunter befindliche Klemmhülse 40 und über den kegelförmigen Anschlussbereich 52 bis an den Bund 57 des Stiftkontaktes 50 einschiebbar ist.This position - in which the carriage element 20 still protrudes from the housing 10 - represents the "assembly position" in which a stripped stranded conductor 8 in the centrally formed in the carriage member 20 through hole 24 into the underlying clamping sleeve 40 and the conical terminal portion 52nd until the collar 57 of the pin contact 50 is inserted.

Der hier noch oberhalb des Gehäuses sichtbare Teil des Schlittenelementes weist eine seitlich geneigte, V-förmige Ausnehmung 30 auf, in die ein entsprechend flaches Werkzeugteil, wie z. B. ein Schraubendreher, einsetzbar ist, um ein eingeschobenes Schlittenelement wieder herauszuhebeln. Für den Einsatz des Werkzeuges ist an der Innenseite der Gehäusewandfläche in jeder Kammer eine Schräge 17 vorgesehen.The visible here above the housing part of the carriage member has a laterally inclined, V-shaped recess 30 into which a correspondingly flat tool part, such. As a screwdriver, can be used to lever out an inserted carriage element again. For the use of the tool, a slope 17 is provided on the inside of the housing wall surface in each chamber.

Ansonsten ist an der Oberfläche des Schlittenelementes 20 eine Nut 31 vorgesehen, in die ein Werkzeug zum Eindrücken des Schlittenelementes 20 in das Gehäuse 10 einfügbar ist.Otherwise, a groove 31 is provided on the surface of the carriage element 20, into which a tool for pressing the carriage element 20 into the housing 10 can be inserted.

Beim Eindrücken des Schlittenelementes 20 bis in seine Endposition, wobei der Anschlag 29 am Ende der Schlittenführung 21 gegen den Anschlag 16 des Rastelementes 15 stößt, wird die Klemmhülse 40 über den kegelförmigen Anschlussbereich 52 geschoben, so dass die darin eingefügten Litzen zwischen der Innenwand der Klemmhülse und der durch die Kegelbasis gebildete Klemmschulter 54 fixiert sind.When pressing the carriage member 20 to its final position, wherein the stop 29 abuts against the stop 16 of the locking element 15 at the end of the carriage guide 21, the clamping sleeve 40 is pushed over the conical connecting portion 52, so that the inserted therein strands between the inner wall of the clamping sleeve and the clamping shoulder formed by the cone base 54 are fixed.

In der Fig. 2 ist die Steckerhälfte 1 in einer perspektivischen Schnittdarstellung mit einer Sicht auch auf den Anschlussbereich 5 gezeigt.In the Fig. 2 the connector half 1 is shown in a perspective sectional view with a view of the connection area 5.

Dabei ist die hier linke bzw. vordere Schlittenelementreihe bereits in das Gehäuse 10 eingeschoben gezeigt, während die rechte bzw. hintere Schlittenelementreihe noch aus dem Gehäuse hervorragt.Here, the left or front carriage element row is shown already inserted into the housing 10, while the right and rear carriage element row still protrudes from the housing.

Weiterhin ist das vordere linke Schlittenelement 20 in einer geschnittenen Darstellung gezeigt, so dass deutlich erkennbar ist, dass für das Einfädeln eines Litzenleiters der sich verengende Trichterausgang 25 des Schlittenelementes einen kleineren Durchmesser aufweist, als die darunter angeordnete Klemmhülse 40. Damit wird verhindert, dass vereinzelte Drähte eines Litzenleiters sich eventuell im Bereich der abgekanteten Halterung 42 der Klemmhülse verklemmen.Furthermore, the front left slide element 20 is shown in a sectional view, so that it can be clearly seen that for the threading of a stranded conductor, the narrowing funnel exit 25 of the carriage element has a smaller diameter than the clamping sleeve 40 arranged underneath Wires of a stranded conductor may jam in the region of the bent bracket 42 of the clamping sleeve.

In dem hier bereits abgesenkt gezeigten Schlittenelement 20 ist das aufeinandertreffen des Anschlages 29 der Schlittenführung 21 auf das Rastelement 15 erkennbar. Bei eingefügten Litzenleitern verbleibt das Schlittenelement in dieser Position, da die Klemmhülse durch die Aufweitung ihres Durchmessers der dazwischen liegenden Litzen auf der Klemmschulter 54 festgehalten wird.In the carriage element 20, which is already shown lowered, the collision of the stop 29 of the carriage guide 21 with the catch element 15 can be seen. When inserted stranded conductors, the carriage element remains in this position, since the clamping sleeve is held by the widening of its diameter of the intervening strands on the clamping shoulder 54.

Während bei nicht eingeschobenen Litzenleiter die an den Eckbereichen 23 des Schlittenelementes 20 angeformten Wulste 33 ein unbeabsichtigtes Abgleiten in Richtung des Stiftkontaktes verhindern.While at not inserted stranded conductor formed on the corner portions 23 of the carriage member 20 beads 33 prevent unintentional sliding in the direction of the pin contact.

Die Fig. 3 zeigt die Steckerhälfte 2 mit einem Steckergehäuse 10' in einer Schnittdarstellung mit mindestens einem darin angeordneten Buchsenkontakt 60.The Fig. 3 shows the connector half 2 with a connector housing 10 'in a sectional view with at least one socket contact 60 arranged therein.

Aus der hier gezeigten Sicht ist erkennbar, dass das Steckergehäuse zwar grundsätzlich ähnlich dem des Stiftkontakte aufnehmenden Gehäuses aufgebaut ist, jedoch ist zur Aufnahme der Buchsenkontakte eine etwas veränderte Konstruktion erfordert.From the point of view shown here it can be seen that the plug housing is basically constructed similar to the housing receiving the pin contacts, however, a slightly different construction is required to accommodate the socket contacts.

Dabei ist der Buchsenkontakt 60 mit der zum Teil geschlitzten Steckseite 61 bis zum Anschlag 14 in den hier röhrenförmigen Haltebereich 13 eingefügt und mittels der Rastelemente 15 verrastet.In this case, the socket contact 60 is inserted with the partially slotted plug side 61 up to the stop 14 in the here tubular holding portion 13 and locked by means of the locking elements 15.

Weiterhin zeigt diese Figur, in der auch die Klemmhülse 40 geschnitten dargestellt ist, den Anschlussbereich 62, bestehend aus der kegelförmigen Spitze 63 an dem Verbindungsstift 66 an den sich die Anschlagfläche 65 der buchsenförmigen Steckseite 61 anschließt.Furthermore, this figure, in which the clamping sleeve 40 is shown cut, the connection portion 62, consisting of the conical tip 63 on the connecting pin 66 to which the stop surface 65 of the sleeve-shaped plug side 61 connects.

Dabei ragt die kegelförmige Spitze 63 in der "Bestückungsposition" bereits in die Klemmhülse 40 hinein, während sich die Klemmschulter 64 noch außerhalb der Klemmhülse befindet.In this case, the conical tip 63 already protrudes into the clamping sleeve 40 in the "loading position", while the clamping shoulder 64 is still located outside the clamping sleeve.

Das untere Ende der Klemmhülse 40 weist eine nach außen gerichtete trichterförmige Aufweitung 44 auf, die beim Absenken der Klemmhülse mit ihrer Innenwandung eine Haltekraft auf die zwischen Klemmhülse und Klemmschulter angeordnete Litzenleiter ausübt.The lower end of the clamping sleeve 40 has an outwardly directed funnel-shaped widening 44, which exerts a holding force on the stranded conductor arranged between clamping sleeve and clamping shoulder when the clamping sleeve is lowered with its inner wall.

Aus dieser Darstellung ist weiterhin leicht erkennbar, dass ein genügend großer Kreisring zwischen der Klemmhülse und der Spitze zum Einschieben für die Litzen eines elektrischen Leiters zur Verfügung steht, so dass die Litzen ohne Kraftaufwand bis maximal an den Anschlag 65 unterhalb der Klemmschulter 64 anstoßen können.From this representation, it is still easy to see that a sufficiently large circular ring between the clamping sleeve and the tip for insertion for the strands of an electrical conductor is available, so that the strands can abut without effort to a maximum of the stop 65 below the clamping shoulder 64.

Dabei ist der Innendurchmesser der Hülse ein wenig größer gewählt als der Durchmesser der Klemmschulter am Kegelende des Anschlussbereiches eines Stift- oder Buchsenkontaktes ― aber mindestens so groß, dass der kleinste vorgesehene Litzenleiter bereits sicher gehalten wird.The inner diameter of the sleeve is chosen to be slightly larger than the diameter of the clamping shoulder at the cone end of the connection region of a pin or socket contact - but at least so large that the smallest intended stranded conductor is already securely held.

Die Klemmhülse 40, gezeigt in der Fig. 4, ist als gerollte, federnde Klemmhülse gefertigt und weist einen mäanderförmigen Schlitz 41 längs der Hülsenwand auf, so dass bei einer radialen Aufweitung eine federnde Wirkung gesichert ist.The clamping sleeve 40, shown in the Fig. 4 is made as a rolled, resilient clamping sleeve and has a meandering slot 41 along the sleeve wall, so that a resilient effect is secured in a radial expansion.

Eine der Endseiten ist mit einem nach außen abgekanteten mehrfach durch Trennschlitze 43 unterbrochenen Haltering 42 versehen, während die gegenüberliegende Seite eine trichterförmige Aufweitung 44 aufweist.One of the end faces is provided with a retaining ring 42, which is bent outwards several times through separating slots 43, while the opposite side has a funnel-shaped widening 44.

Der in Fig. 5 gezeigte Stiftkontakt 50 ist als Drehteil ausgeführt und weist eine stiftförmige Steckseite 51 und einen Anschlussbereich 52 mit einer kegelförmigen Spitze 53 auf.The in Fig. 5 shown pin contact 50 is designed as a rotating part and has a pin-shaped insertion side 51 and a connection portion 52 with a conical tip 53.

Zwischen Steckseite 51 und Anschlussbereich 52 ist ein zylinderförmiger Bund 57 angeformt, dessen zur Kegelspitze weisende Kreisringfläche als Anschlagfläche 55 definiert ist. Die kegelförmige Spitze ist mittels eines Verbindungsstiftes 56 mit dem Bund 57 einstückig verbunden.Between the insertion side 51 and the connection region 52, a cylindrical collar 57 is formed, whose annular surface facing the apex is defined as a stop surface 55. The conical tip is integrally connected by means of a connecting pin 56 with the collar 57.

Die Kanten der Kegelbasis bilden eine Klemmschulter 54, über die bei Anschluss eines Litzenleiters die federnde Klemmhülse 40 gestülpt wird, die eine radial nach innen wirkende Kraft ausübt.The edges of the cone base form a clamping shoulder 54, over which upon connection of a stranded conductor, the resilient clamping sleeve 40 is slipped, which exerts a radially inwardly acting force.

Der in Fig. 6 dargestellte Buchsenkontakt 60 ist wie der bereits beschriebene Stiftkontakt 50 mit einer Steckseite 61 und einem Anschlussbereich 62 versehen. Die Steckseite ist als teilweise geschlitzte Buchse ausgebildet, während der Anschlussbereich 62 mit einer kegelförmigen Spitze 63 versehen ist, an deren Kegelbasis eine Klemmschulter 64 zur Arretierung der Litzen mittels der über dem Anschlussbereich 62 gestülpten Klemmhülse 40 vorgesehen ist.The in Fig. 6 Socket contact 60 shown is like the pin contact 50 already described with a plug side 61 and a connection portion 62 is provided. The plug-in side is designed as a partially slotted socket, while the connection region 62 is provided with a conical tip 63, on whose cone base a clamping shoulder 64 is provided for locking the strands by means of the clamping sleeve 40 which is slipped over the connection region 62.

In der Fig. 7 ist das Schlittenelement 20 vereinzelt in einer perspektivischen Darstellung gezeigt. Dabei ist der Rundkörper 22 mit der Durchgangsbohrung 24 und den angeformten Eckbereichen 23 und der gleichfalls angeformten Schlittenführung 21 ersichtlich.In the Fig. 7 the carriage element 20 is shown isolated in a perspective view. In this case, the round body 22 with the through hole 24 and the integrally formed corner regions 23 and the likewise integrally formed slide guide 21 can be seen.

Aus der Außenfläche der Schlittenführung ragt eine keilförmige Führungsschiene 32 mit der Rastkante 28 hervor, die in einer entsprechend ausgebildete Führungsnut 19 in der Kammer 11 des Steckergehäuses 10, 10' in Steckrichtung gleitet. Wobei die Rastkante 28 gegen die Rastkante 18 in der Kammer stößt und damit ein Herausfallen des Schlittenelementes 20 verhindert.From the outer surface of the carriage guide protrudes a wedge-shaped guide rail 32 with the locking edge 28, which slides in a correspondingly shaped guide groove 19 in the chamber 11 of the plug housing 10, 10 'in the insertion direction. Wherein the locking edge 28 abuts against the locking edge 18 in the chamber and thus prevents falling out of the carriage member 20.

Die Führungsschiene unterbrechend, ist die V-förmige Ausnehmung 30 für den Einsatz eines einfachen Werkzeuges vorgesehen, so dass ein in der Kammer 11 abgesenktes Schlittenelement wieder heraushebelbar ist.Interrupting the guide rail, the V-shaped recess 30 is provided for the use of a simple tool, so that a lowered in the chamber 11 carriage element is again heraushebelbar.

Oberhalb der Ausnehmung 30 im Anschlussbereich 5 ist eine Nut 31 vorgesehen, in die das gleiche Werkzeug wie oben zum Absenken des Schlittenelementes in die Kammer hinein einsetzbar ist.Above the recess 30 in the connection region 5, a groove 31 is provided into which the same tool as above for lowering the carriage element into the chamber can be inserted.

Um ein Abgleiten eines nicht genutzten Schlittenelementes in seine Kammer zu verhindern, sind an der zur Ausnehmung 30 weisenden Seite und über eine bestimmte Länge, Wulste 33 auf den Eckbereichen 23 angeformt, die über die Fläche des jeweiligen Eckbereiches hinausragen und damit gegen die Innenwand der Kammer 11 gedrückt werden.In order to prevent slipping of an unused carriage element into its chamber, bulges 33 are formed on the side facing the recess 30 and over a certain length on the corner regions 23, which project beyond the surface of the respective corner region and thus against the inner wall of the chamber 11 are pressed.

In der Fig. 8a, 8b ist in einer Schnittdarstellung eines Gehäuses 10 für Stiftkontakte das Zusammenspiel der Anschlusseinrichtung, gebildet aus dem Schlittenelement 20, der Klemmhülse 40 und dem Anschlussbereich eines Stiftkontaktes 50 mit einem darin eingeschobenen Litzenleiter 7 gezeigt. Dazu werden die Einzeladern 8 des Litzenleiters 7 zunächst auf eine vorgegebene Länge abisoliert, die etwas länger als die Länge der Klemmhülse 40 sein soll.In the Fig. 8a . 8b is a sectional view of a housing 10 for pin contacts, the interaction of the connection device, formed from the carriage member 20, the clamping sleeve 40 and the terminal portion of a pin contact 50 with a therein inserted stranded conductor 7 is shown. For this purpose, the individual wires 8 of the stranded conductor 7 are first stripped to a predetermined length, which should be slightly longer than the length of the clamping sleeve 40.

Dann werden der Litzenleiter 7 in die Durchgangsbohrung 24 des Schlittenelementes 20 eingeschoben, so dass dessen Ummantelung etwa bis in den Trichterausgang 25 ragt, wobei die Einzelleiter 8 selber unterhalb der Klemmhülse 40 mindestens über die Klemmschulter 54 ragen.Then, the stranded conductor 7 are inserted into the through hole 24 of the carriage member 20, so that its sheath protrudes approximately into the funnel exit 25, wherein the individual conductors 8 themselves project below the clamping sleeve 40 at least over the clamping shoulder 54.

Anschließend wird das Schlittenelement 20 in das Gehäuse 10 eingedrückt, wobei die Einzelieiter um den Schiebeweg des Schlittens über die Kegelspitze 53 verschoben werden und mit Sicherheit über der Klemmschulter des Anschlussbereiches positioniert sind, wobei sie dort je nach Dicke und Anzahl der Litzen von der sich aufweitenden aber federnden Klemmhülse 40 fixiert sind.Subsequently, the carriage member 20 is pressed into the housing 10, wherein the Einzelieiter are shifted by the sliding path of the carriage over the apex 53 and are positioned with certainty on the clamping shoulder of the connection area, where they depending on the thickness and number of strands of the widening but resilient clamping sleeve 40 are fixed.

In der Fig. 9 ist ein pyramidenförmigen Anschlussbereich 52 mit vier Klemmschultern 54 hier für einen Stiftkontakten 50 gezeigt, während in der Fig. 10 einen Buchsenkontakt mit einem pfeilförmigen Anschlussbereich 62 und zwei Klemmschultern 64 dargestellt ist. Eine für diese Varianten vorgesehene Klemmhülse 40' mit einer hier quadratischen Ausführung und einem vereinfachten mäanderförmigen Längsschlitz 41 ist in der Fig. 11 gezeigt.In the Fig. 9 For example, a pyramidal terminal region 52 having four clamping shoulders 54 is shown here for a pin contact 50, while in FIG Fig. 10 a female contact with an arrow-shaped terminal portion 62 and two clamping shoulders 64 is shown. A provided for these variants clamping sleeve 40 'with a square design here and a simplified meander-shaped longitudinal slot 41 is in the Fig. 11 shown.

Darüber hinaus kann auch eine polygone Form des den Anschlussbereich formenden Volumenkörpers vorsehbar sein, der eine dazu entsprechend modifizierte Klemmhülse erfordert.In addition, it is also possible to provide a polygonal shape of the volume body forming the connection region, which requires a correspondingly modified clamping sleeve.
