Description

Beschreibungdescription

Die Erfindung betrifft einen Anschlusskontakt für elektrische Leiter in einem Isoliergehäuse mit in einzelnen Kammern angeordneten elektrischen Kontakten.The invention relates to a connection contact for electrical conductors in an insulating housing arranged in individual chambers electrical contacts.

Ein derartiger Abschlusskontakt wird speziell bei elektrischen Leitern benötigt, die als Litzenleitern ausgebildet sind.Such a termination contact is needed especially for electrical conductors that are designed as stranded conductors.

Stand der TechnikState of the art

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.

Aufgabenstellungtask

Der Erfindung liegt die Aufgabe zugrunde, einen einfachen Anschlusskontakt auszubilden, bei dem der Anschluss von unterschiedlich gearteten elektrischen Leitern mit wenigen und einfachen Bauteilen werkzeuglos erfolgt, wobei ein möglichst großer Bereich bezüglich der zu kontaktierenden Drahtquerschnitte erfasst wird.The invention has for its object to form a simple terminal contact, in which the connection of different types of electrical conductors with few and simple components without tools, with the largest possible area is detected with respect to the wire cross-sections to be contacted.

Diese Aufgabe wird dadurch gelöst, dass der Anschlusskontakt aus einer Stromschiene gebildet ist, mit einem entgegen der Steckrichtung widerhakenförmig gebogenen Kontaktierungsbereich, umgeben von einer Klemmhülse, die in axialer Ausrichtung mit einem Schlittenelement verbunden ist, das eine Durchgangsbohrung zur Einführung eines elektrischen Leiters aufweist, angeordnet in jeweils einer einzelnen Kammer des Steckergehäuses, wobei das Schlittenelement über dem Kontaktierungsbereich der Stromschiene aufschiebbar und wieder abziehbar ist, so dass auf einen zwischen dem Kontaktierungsbereich und der Klemmhülse eingefügten elektrischen Leiter eine fixierende Kraft einwirkt.This object is achieved in that the terminal contact is formed from a busbar, with a barb-shaped contacting area opposite to the plug-in direction, surrounded by a clamping sleeve which is connected in axial alignment with a carriage element, the a through hole for insertion of an electrical conductor, arranged in each case in a single chamber of the plug housing, wherein the carriage member is pushed over the contacting region of the bus bar and again peelable, so that acting on a inserted between the contacting region and the clamping sleeve electrical conductor acts a fixing force.

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 ein für ein- oder mehrdrähtige elektrische Leiter werkzeugloses Anschlusssystem zur Verfügung steht, bei dem die Leiter mittels einer federnden Hülse auf den Anschlussbereich elektrischer Kontakte fixierbar sind. Dazu sind in dem Steckergehäuse eine Anzahl von Kammern angeordnet, in denen jeweils eine Klemmvorrichtung für einen Litzenleiter vorgesehen ist. Die Klemmvorrichtung wird als Anschlusseinrichtung für elektrische Leiter aus einem axial verschiebbaren Schlittenelement gebildet, das zusammen mit einer Klemmhülse auf den Anschlussbereich eines elektrischen Kontaktelementes aufschiebbar ist, das hier eine widerhakenähnliche Form aufweist. Dabei ist speziell für Litzenleiter Voraussetzung, dass deren Zuführung in einen Kontaktierungsbereich kraftlos erfolgt, um ein Verdrehen oder Verbiegen einzelner Adern bis zum Erreichen eines Anschlagpunktes möglichst zu verhindern.
Dabei wird bei der Montage der abisolierte Teil eines Litzenleiters in eine durch das Schlittenelement hindurchführende Bohrung einschließlich einer am Schlitten fixierten Klemmhülse geführt.
Dann wird das Schlittenelement in Steckrichtung mit dem Litzenleiter axial in das Gehäuse hinein verschoben.
Dabei ist von Vorteil, dass entsprechende konstruktive Maßnahmen wie eines in einer Nut auf Reibung gleitenden Führungskeiles in der Kammer und dem Schlittenelement ein unbeabsichtigtes Abgleiten eines Schlittenelementes in Richtung des Kontaktelementes verhindert.The advantages achieved by the invention are in particular that with this one for single or stranded electrical conductor tool-free connection system is available, in which the conductors are fixed by means of a resilient sleeve on the connection region of electrical contacts. For this purpose, a number of chambers 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 conductors of an axially displaceable slide element, which is pushed together with a clamping sleeve on the connection region of an electrical contact element, which here has a barb-like shape. It is a prerequisite for stranded conductors in particular that their supply into a contacting area is powerless in order to prevent twisting or bending of individual wires as far as possible until an abutment point is reached.
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.
Then, the carriage member is axially displaced in the insertion direction with the stranded conductor into the housing.
It is advantageous that appropriate structural measures such as a sliding in a groove on friction guide wedge in the chamber and the carriage element prevents unintentional sliding of a carriage element in the direction of the contact element.

Mit zunehmender Endstellung des Schlittenelementes wird die federnd ausgebildete Klemmhülse über den widerhakenförmigen Kontaktierungs- oder Anschlussbereich mit dem elektrischen Leiter geschoben.
Dabei gewährleistet die vorteilhaft mit einem mäanderförmigen, durchgehenden Längsschlitz versehene Klemmhülse eine stets der Anzahl und Größe der unterschiedlich gearteten elektrischen Leiter angepasste, einschnürende Kraft auf den Anschlussbereich.
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 elektrische Leiter auch wieder freigegeben wird.
Der Isolierkörper kann mittels entsprechend ausgebildeter elektrischer Kontakte als Monoblock für Steckerverbinder oder in Segmenttechnik für Reihenklemmen ausgeführt sein.
Weiterhin ist bei einem Monoblock vorgesehen, die einfach zu fertigende Stromschiene mit einer Buchse oder einem Stiftstecker zu verbinden, so dass mit einem derartigen Kontaktierungs- oder Anschlussbereich ein Steckverbinder auszubilden ist.With increasing end position of the carriage element, the resiliently formed clamping sleeve is pushed over the barb-shaped contacting or connection region with the electrical conductor.
The advantageously provided with a meandering, continuous longitudinal slot clamping sleeve ensures an always the number and size of different types of electrical conductors adapted, constricting force on the connection area.
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 electrical conductor is also released again.
The insulating body can be designed by means of appropriately trained electrical contacts as a monobloc for plug connector or in segmental technology for terminal blocks.
Furthermore, it is provided in a monoblock to connect the easily manufactured busbar with a socket or a male connector, so that with such a Kontaktierungs- or connection area a connector is to be formed.

In der Fig. 1 ist in einer geschnittenen Darstellung ein Isolierkörper 1 gezeigt, in dem ein verschiebbares Schlittenelement 2 mit einer damit verbundenen Klemmhülse 3 in einer Kammer 11 angeordnet ist.
Weiterhin ist eine Stromschiene 4 in dem Isolierkörper 1 vorgesehen, deren Kontaktierungsbereich 41 die Form eines Widerhakens aufweist.
Dabei ist die Stromschiene 4 so in dem Isolierkörper 1 angeordnet, dass die verschiebbare Klemmhülse 3 immer den Kontaktierungsbereich 41 umfasst. Wobei im geöffneten Montagezustand, bei dem der Schlitten 2 maximal aus dem Isoliergehäuse 1 herausragt, das Widerhakenende 42 in etwa mit der trichterförmigen Aufweitung 33 auf der gleichen Linie sind, so dass eine maximale Schlitzöffnung zum kraftlosen Einfädeln eines durch die Durchgangsbohrung 21 des Schlittenelementes geführten Litzenleiters entsteht. Während beim Eindrücken des Schlittenelementes in das Isoliergehäuse die einzelnen Litzen zunehmend gegen die Wand der Klemmhülse 3 gedrückt und an dem eine Klemmschulter bildenden Widerhakenende 42 fixiert werden.
Das gilt ebenso für die Nutzung eines eindrähtigen elektrischen Leiter.In Fig. 1, an insulating body 1 is shown in a sectional view, in which a displaceable slide element 2 is arranged with a clamping sleeve 3 connected thereto in a chamber 11.
Furthermore, a bus bar 4 is provided in the insulating body 1, the contacting region 41 has the shape of a barb.
In this case, the busbar 4 is arranged in the insulating body 1, that the displaceable clamping sleeve 3 always includes the contacting region 41. Wherein, in the open mounting state, in which the carriage 2 protrudes maximally from the insulating housing 1, the barbed end 42 approximately in the same direction with the funnel-shaped widening 33, so that a maximum slot opening for powerless threading a guided through the through hole 21 of the carriage element stranded conductor arises. While the individual strands are increasingly pressed against the wall of the clamping sleeve 3 and in which a clamping shoulder forming barbs end 42 are fixed when pressing the carriage element in the insulating.
This also applies to the use of a single-wire electrical conductor.

Das Schlittenelement 2 ist prinzipiell als Rechteckkörper geformt, mit einer Durchgangsbohrung 21, die einen nach innen sich verengenden Trichterausgang 22 aufweist.
Zum Aushebeln eines im Isoliergehäuse 1 eingeschobenen Schlittenelementes 2, z. B. mit einem Schraubendreher, ist im hier oberen Bereich des Isoliergehäuses eine Schräge 12 und dazu passend im Schlitten eine keilförmige Ausnehmung 24 vorgesehen.
Unterhalb der keilförmigen Ausnehmung ist eine Schlittenführung vorgesehen, die aus einem langgezogenen Keil 25 am Schlitten und einer Führungsnut 14 im Isoliergehäuse gebildet ist, wobei die Führungsnut im oberen Bereich des Isoliergehäuses mit einem Vorsprung 13 endet, gegen die das vorstehende Keilende 26 des Schlittenelementes anstößt und das Herausragen und letztlich ein Herausfallen des Schlittens aus dem Isoliergehäuse verhindert. Die Klemmhülse 3 ist mit dem nach außen rechtwinklig abgebogenen Haltering 32 in einer Haltenut 23 gehalten, und zwar so, dass das Zentrum des Trichterausganges etwa mittig zum darunter angeordneten widerhakenförmigen Kontaktierungsbereich 41 zur hier rechten Wand der Klemmhülse 3.The carriage element 2 is in principle shaped as a rectangular body, with a through-bore 21 which has a funnel exit 22 narrowing inwards.
For levering a slid in the insulating housing 1 slide element 2, z. B. with a screwdriver, in the upper region of the insulating housing, a slope 12 and to match a wedge-shaped recess 24 is provided in the carriage.
Below the wedge-shaped recess, a slide guide is provided, which is formed of an elongated wedge 25 on the carriage and a guide groove 14 in the insulating housing, wherein the guide groove in the upper region of the insulating housing ends with a projection 13 against which abuts the projecting wedge end 26 of the carriage member and the protruding and ultimately falling out of the carriage from the insulating prevented. The clamping sleeve 3 is held with the outwardly bent at right angles retaining ring 32 in a retaining groove 23, in such a way that the Center of the funnel exit approximately centrally to the barb-shaped contacting region 41 arranged therebelow to the right wall of the clamping sleeve 3.

Die Fig. 2 zeigt eine perspektivische, geschnittene Darstellung des bereits im Schnitt aus der Fig. 1 gezeigten Isoliergehäuses 1 mit dem Schlittenelement 2, der Klemmhülse 3 und der Stromschiene 4.
An der Innenrückwand ist hier noch die bereits erwähnte Führungsnut 14 erkennbar, in der der Schlittenführungskeil 25 geführt ist.2 shows a perspective, sectional view of the already shown in section from FIG. 1 insulating housing 1 with the carriage element 2, the clamping sleeve 3 and the busbar. 4
On the inner rear wall is here still the aforementioned guide groove 14 can be seen, in which the carriage guide wedge 25 is guided.

Die Klemmhülse 3 in der Fig. 3 ist als rechteckige, federnde Klemmhülse gefertigt und weist einen mäanderförmigen Schlitz 31 längs einer Hülsenwand auf, so dass bei einer Aufweitung durch in den Schlitz zwischen dem Widerhakenende 42 und der Hülsenwand eingefügter unterschiedlich gearteter elektrische Leiter, beim Absenken des Schlittenelementes in die Kammer des Isolierkörpers, eine federnde Wirkung gesichert ist.
Dabei ist die eine Endseite mit einem nach außen abgekanteten mehrfach durch Trennschlitze 34 unterbrochenen Halterand 32 versehen, während die gegenüberliegende Seite eine trichterförmige Aufweitung 33 aufweist.The clamping sleeve 3 in Fig. 3 is made as a rectangular, resilient clamping sleeve and has a meandering slot 31 along a sleeve wall, so that at an expansion by inserted into the slot between the barbed end 42 and the sleeve wall different kind of electrical conductor when lowering the carriage element is secured in the chamber of the insulating body, a resilient effect.
In this case, the one end side is provided with an outwardly bent multiple interrupted by separating slots 34 retaining edge 32, while the opposite side has a funnel-shaped widening 33.

Eine Variante der Klemmhülse 3 ist in der Fig. 4 ersichtlich, bei der der Schlitz 31' im mittleren Bereich der Klemmhülse einen nahezu diagonalen Verlauf aufweist.A variant of the clamping sleeve 3 can be seen in Fig. 4, in which the slot 31 'in the central region of the clamping sleeve has a nearly diagonal course.

Die in den beiden Figuren gezeigte Stromschiene 4 ist jeweils mit einem Leiterplattenanschlussende 43 ausgestattet und daher auch in einer gewinkelten Form durch das Isoliergehäuse 1 geführt. Wobei diese Gehäuse zusätzlich noch aneinanderreihbar sind.
Es ist jedoch auch vorgesehen, das Anschlussende als Stift- oder Buchsenkontakt auszubilden, bzw. mit einem solchen zu verbinden, so dass eine steckbare Konfiguration denkbar ist.The bus bar 4 shown in the two figures is in each case equipped with a printed circuit board connection end 43 and therefore also guided in an angled form through the insulating housing 1. Whereby these housings are additionally stackable.
However, it is also provided to form the terminal end as a pin or socket contact, or to connect with such, so that a pluggable configuration is conceivable.
