Die vorliegende Erfindung betrifft einen Schneidklem ontakt . Die australische Patentschrift 90449/98 beschreibt eine Stromsteckdose mit Schneidklemm- kontakten zum Anschließen einer isolierten Ader daran.

Bei der Anordnung, wie sie zuletzt beschrieben wurde, kann ein Trager vorgesehen sein, der bezüglich des leitenden Elements gleiten kann und eine Öffnung aufweist, in die die Ader so eingeführt werden kann, das sich die Ader in die Öffnung und auch durch die Apertur an einer von dem Kanal beabstandeten Partie der Apertur erstreckt, wobei die Ader dann in den Kanal bewegt werden kann, um den Kontakt herzustellen, indem der Trager zum Tragen der Ader in den Kanal geschoben wird. Bei einer Anordnung, wie sie in derThe present invention relates to an insulation displacement contact. The Australian patent specification 90449/98 describes a power socket with insulation displacement contacts for connecting an insulated wire to it. In particular, an insulation displacement contact is described which is formed from a conductive element with an aperture therein, opposing portions of the edge of the aperture defining opposing contact portions that extend inwardly toward one another and having inner opposite contact edges that define a channel therebetween, thereby creating a A wire with a conductor surrounded by insulation can be inserted into the channel and the channel can be printed to cut the insulation of the wire and to make electrical contact between the contact edges and the conductor. In the arrangement as described last, a carrier can be provided which can slide with respect to the conductive element and has an opening into which the wire can be inserted so that the wire fits into the opening and also through the aperture a portion of the aperture spaced from the channel, the wire then being moved into the channel to make contact by pushing the carrier into the channel to carry the wire. With an arrangement as in the
Patentschrift 90449/98 beschrieben ist, hat sich herausgestellt, daß das leitende Element eine gewisse Neigung aufweist zu knicken, wenn eine Ader abgeschlossen wird, es sei denn, das leitende Element ist aus einem relativ schweren Material hergestellt.No. 90449/98, it has been found that the conductive element has a tendency to kink when a wire is terminated, unless the conductive element is made of a relatively heavy material.
Unter einem Gesichtspunkt stellt die Erfindung einen Schneidklemmkontakt bereit, der aus einem leitenden Element mit einer Apertur darin ausgebildet ist, wobei gegenüberliegende Partien der Kante der Apertur gegenüberliegende Kontaktpartien definieren, die sich nach innen aufemanderzu erstrecken und die innere gegenüberliegende Kontaktkanten aufweisen, die einen Kanal dazwischen definieren, wodurch eine Ader mit einem von Isolierung umgebenen Leiter m den Kanal eingeführt und in den Kanal gedruckt werden kann, um die Isolierung der Ader zu schneiden und einen elektrischen Kontakt zwischen den Kontaktkanten und dem Leiter herzustellen, wobei der Schneidklemmkontakt an gegenüberliegenden Seitenkanten des leitenden Elements jeweilige Flansche aufweist, die allgemein parallel zu der Erstreckungsrichtung des Kanals verlaufen und zueinander entgegengesetzt gerichtet sind. Insbesondere kann das leitende Element eine zentrale Partie definieren, die in der Erstreckungsrichtung des Kanals länglich ist, und die Flansche können sich in der Richtung und aus der Ebene der zentralen Partie heraus zu jeweiligen gegenüberliegenden Seiten dieser Ebene erstrecken. Die Kontaktpartien können sich so von im wesentlichen fixierten Enden unter einem Winkel zu der Erstreckungsrichtung des Kanals erstrecken, daß sie aufeinanderzulaufen, und freie Endteile aufweisen, die sich allgemein parallel zueinander erstrecken und die Kontaktkanten definieren. Freie Endkanten der freien Endteile können sich bezüglich der Erstreckungsrichtung des Kanals in Querrichtung erstrecken und zueinander in der Richtung auseinanderlaufen, die von den im wesentlichen fixierten Enden wegfuhrt, so daß eine Einfuhrungsstruktur zum Erleichtern des Eintritts der Ader in den Kanal gebildet wird. Die freien Endkanten können sich bezuglich der Ebene der zentralen Partie unter einem Winkel erstrecken und bezuglich dieser Ebene entgegengesetzt verlaufen, so daß sie dazu neigen, eine Verschiebung der Kontaktpartien in entgegengesetzten Drehrichtungen aus der Ebene heraus einzufuhren, wenn eine Ader in Kontakt mit den freien Endkanten zur Einfuhrung in den Kanal gebracht wird. Die Erfindung wird nun beispielhaft unterIn one aspect, the invention provides an insulation displacement contact formed from a conductive member having an aperture therein, with opposing portions of the edge of the Aperture define opposing contact portions that extend inwardly toward one another and have inner opposing contact edges that define a channel therebetween, whereby a wire with a conductor surrounded by insulation can be inserted into the channel and printed into the channel to isolate the wire to cut and establish electrical contact between the contact edges and the conductor, the insulation displacement contact having respective flanges on opposite side edges of the conductive element, which flanges are generally parallel to the direction of extension of the channel and are opposite to one another. In particular, the conductive element can define a central part which is elongate in the direction of extension of the channel, and the flanges can extend in the direction and out of the plane of the central part to respective opposite sides of this plane. The contact portions may extend from substantially fixed ends at an angle to the direction of extension of the channel to converge and have free end portions that extend generally parallel to one another and define the contact edges. Free end edges of the free end portions may extend transversely of the direction of extension of the channel and diverge from each other in the direction leading away from the substantially fixed ends, so that an insertion structure is formed to facilitate the entry of the wire into the channel. The free end edges can extend at an angle with respect to the plane of the central part and run opposite to this plane, so that they tend to introduce a shift of the contact parts in opposite directions of rotation out of the plane when a wire comes into contact with the free end edges is brought into the canal for introduction. The invention will now be exemplified under

Figur 9 eine Ruckansicht einer mit elektrischen Verbindern und Adertragern, wie in Figur 7 gezeigt, ausgestatteten Stromsteckdose. Der in Figur 1 gezeigte Schneidklemmkontakt 2 besteht aus einem länglichen, allgemein ebenen leitenden Element 4 mit einer Reihe von entlang seiner Lange beabstandeten Aperturen 6. Die Kante jeder Apertur 6 definiert ein paar nach innen ragender Kontaktpartien 8, die zwischen sich einen relativ schmalen Kanal 10 definieren. Adern, die m die Aperturen 6 eingeführt werden, indem die Adern quer zu dem Element 4 m Längsrichtung bewegt werden, können seitlich und in Längsrichtung des Elements 8 bewegt werden, damit sie m einen Kanal 10 so eintreten, daß gegenüberliegende Kontaktkanten der Partien 8 die Adern kontaktieren, ihre Isolierung schneiden und eine elektrische Verbindung mit Innenleitern der Adern herstellen. Um das Fuhren der Ader in den Kanal zu erleichtern, können die Partien 8 jeweilige Vorderkanten 12 aufweisen, und diese können, wie gezeigt, bezuglich der Ebene des Elements entgegengesetzt geneigt sein. Wenn eine Ader mit den Kanten 12 wahrend der Einfuhrung der Ader in den Kanal 10 in Eingriff gebracht wird, kommt es somit zu einer Verdrehungsverschiebung der Partien 8 relativ zu der Längsrichtung des Elements 4. Dadurch werden die Partien 8 relativ zu der Ebene des Elements 4 entgegengesetzt verschoben.FIG. 9 shows a rear view of a power socket equipped with electrical connectors and wire carriers, as shown in FIG. 7. The insulation displacement contact 2 shown in FIG. 1 consists of an elongated, generally planar conductive element 4 with a series of apertures 6 spaced along its length. The edge of each aperture 6 defines a pair of inwardly projecting contact parts 8, which have a relatively narrow channel 10 between them define. Veins, which are introduced into the apertures 6 by moving the wires transversely to the element 4 m in the longitudinal direction, can be moved laterally and in the longitudinal direction of the element 8 so that they enter a channel 10 in such a way that opposite contact edges of the parts 8 Contact the wires, cut their insulation and establish an electrical connection with the inner conductors of the wires. To lead the vein into the channel the portions 8 may have respective leading edges 12 and, as shown, these may be inclined opposite to the plane of the element. If a wire is brought into engagement with the edges 12 during the insertion of the wire into the channel 10, there is thus a rotational displacement of the parts 8 relative to the longitudinal direction of the element 4. This makes the parts 8 relative to the plane of the element 4 oppositely shifted.
Der Schneidklemmkontakt 20 der Figuren 2 bis 9 wird aus einem leitenden Element 22 laminarer Form, das allgemein eben ist, gebildet. Entlang der Lange des Elements 22 sind Aperturen 24 beabstandet, die sich durch eine Zentrale Partie 26 des Elements 22 erstrecken und m der Langserstreckungsπchtung des Elements 22 beabstandet sind. In diesem Fall gibt es zwei Aperturen 24, die jeweils so konfiguriert sind, daß sie zwei jeweilige Kontaktstrukturen 28, 30 definieren, wobei die Kontaktstrukturen 28, 30 jeder Apertur 24 in der Langserstreckungsπchtung des Elements 22 beabstandet sind. Da die beiden Aperturen 24 und die dazugehörige Kontaktstruktur 28, 30 im wesentlichen die gleichen sind, beschrankt sich die folgende Beschreibung auf eine dieser Aperturen und dazugehörige Kontaktstrukturen.The insulation displacement contact 20 of Figures 2 to 9 is formed from a laminar shape conductive member 22 which is generally planar. Apertures 24 are spaced along the length of the element 22, which extend through a central part 26 of the element 22 and are spaced apart in the longitudinal direction of the element 22. In this case there are two apertures 24, which are each configured such that they define two respective contact structures 28, 30, the contact structures 28, 30 of each aperture 24 being spaced apart in the longitudinal direction of the element 22. Since the two apertures 24 and the associated contact structure 28, 30 are essentially the same, the following description is limited to one of these apertures and associated contact structures.
Wie am besten in Figur 3 gezeigt, weist jede der Kontaktstrukturen 28, 30 ein Paar von durch die Kante der dazugehörigen Apertur 24 definierten Kontaktpartien 32 auf, die sich von gegenüberliegenden Seiten des Elements 22 aus nach innen aufeinander zu erstrecken. Jedes Paar von Kontaktpartien 32 definiert dazwischen einen jeweiligen Kanal 42. Jede Kontaktpartie 32 weist einen Teil 32a auf, der sich von einem jeweiligen, im wesentlichen fixierten Ende neben einer jeweiligen Kante des Elements 22 erstreckt, wobei er bezuglich der Langserstreckungsπchtung des Elements 22 unter einem Winkel angeordnet ist, wobei die Richtung in den Zeichnungen mit "A" markiert ist. Die Teile 32a jedes Paars von Kontaktpartien 32 laufen in Richtung "A" aufeinander zu. An äußeren Enden der Kontaktpartien 32 sind freie Endteile 32b definiert, die sich ungefähr parallel zu der Richtung "A" erstrecken und an Innenkanten davon Kontaktkanten 32c definieren. Die Kontaktkanten 32c an jedem Paar von Kontaktpartien 32 definieren dazwischen einen jeweiligen der Kanäle 42. An freien Enden der Kontaktteile 32b sind querverlaufende freie Endkanten 32d vorgesehen, die in der Richtung "A" auseinanderlaufen, und diese definieren eine jeweilige Einfuhrungsstruktur 34 (Figur 2) zum Erleichtern des Eintritts von Adern in den dazugehörigen Kanal 42. Diese Kanten 32d sind, wie gezeigt, durch geneigte Oberflachen definiert, wobei die Oberflachen bezuglich der Ebene des Elements 22 entgegengesetzt geneigt sind, so daß bei Einfuhrung einer Ader in eine Kanalstruktur 42, wie sie durch ein paar Kanten 32d dargestellt wird, eine Tendenz vorliegt, daß die jeweiligen Kontaktpartien 32 bezüglich der Längsrichtung des Kontaktelements 22 relativ entgegengesetzt gedreht werden und zu jeweiligen gegenüberliegenden Seiten der Ebene des Elements 22 verschoben werden.As best shown in FIG. 3, each of the contact structures 28, 30 has a pair of contact portions 32 defined by the edge of the associated aperture 24 that extend inwardly toward one another from opposite sides of the element 22. Each pair of contact portions 32 define a respective channel 42 therebetween. Each contact portion 32 has a portion 32a which extends from a respective substantially fixed end adjacent a respective edge of the element 22, with respect to the longitudinal direction of the element 22 under one Angle is arranged, the direction being marked in the drawings with "A". The Parts 32a of each pair of contact portions 32 converge towards "A". Free end portions 32b are defined at outer ends of the contact portions 32, which extend approximately parallel to the direction "A" and define contact edges 32c at inner edges thereof. The contact edges 32c on each pair of contact portions 32 define a respective one of the channels 42 therebetween. At free ends of the contact parts 32b, transverse free end edges 32d are provided which diverge in the direction "A", and these define a respective insertion structure 34 (FIG. 2) to facilitate the entry of veins into the associated channel 42. These edges 32d are, as shown, defined by inclined surfaces, the surfaces being oppositely inclined with respect to the plane of the element 22, so that when a wire is inserted into a channel structure 42, such as it is represented by a few edges 32d, there is a tendency that the respective contact parts 32 are rotated relatively opposite with respect to the longitudinal direction of the contact element 22 and are shifted to respective opposite sides of the plane of the element 22.
Jeder Kanal 42 fuhrt in der Richtung "A" von den fixierten Enden der Kontaktpartien 32 weg zu einer vergrößerten Partie 24a, 24b der jeweiligen Apertur 24. Das heißt, es liegt eine vergrößerte Aperturpartie 24a neben dem Kanal 42 für die Kontaktstruktur 28 an einem Ende der Apertur 24 und eine ahnliche vergrößerte Aperturpartie 24b neben der Kontaktstruktur 30 an dem anderen Ende der Apertur 24 vor.Each channel 42 leads in the direction "A" away from the fixed ends of the contact sections 32 to an enlarged section 24a, 24b of the respective aperture 24. That is, there is an enlarged aperture section 24a next to the channel 42 for the contact structure 28 at one end the aperture 24 and a similar enlarged aperture portion 24b next to the contact structure 30 at the other end of the aperture 24.
Die Aperturpartien 24a, 24b definieren auch auf ihren gegenüberliegenden Seiten ausgeschnittene Aperturteile 44, die m der zu der Richtung "A" entgegengesetzten Richtung nach außen auseinanderlaufen. Diese definieren Kanten 36 der Kontaktpartien 32. Im Vergleich mit der in Figur 1 gezeigten Anordnung laßt sich infolgedessen beobachten, daß die Kontaktpartien 32 relativ langer (Abmessung " L" in Figur 3) sind und eine geringere Breite aufweisen αnd dadurch eine etwas größere Flexibilität als die Kontaktelemente 8 in Figur 1 aufweisen.The aperture parts 24a, 24b also define aperture parts 44 which are cut out on their opposite sides and which diverge outwards in the direction opposite to the direction "A". These define edges 36 of the contact parts 32. In comparison with the arrangement shown in FIG. 1, it can consequently be observed that the contact parts 32 are relatively longer (dimension "L" in Figure 3) and have a smaller width and thus have a slightly greater flexibility than the contact elements 8 in Figure 1.
Die Kanten 38 der Kontaktpartien 32 der Kontaktstruktur 28, ihre gegenüberliegenden Kanten 36, werden durch eine Partie des Umfangs der Aperturpartie 24b definiert. Diese Kanten 38 sind bezüglich der Erstreckungsrichtung des Elements 22 in Querrichtung angeordnet und laufen in der Richtung A" zusammen. Die Kanten 38 der Kontaktpartien 32 der Kontaktstruktur 30 werden durch eine andere Partie des Umfangs einer weiteren Partie 24c der Apertur 24 definiert. Auch diese Kanten 38 sind bezuglich der Erstreckungsrichtung des Elements 22 in Querrichtung angeordnet und laufen in der Richtung "A" zusammen.The edges 38 of the contact parts 32 of the contact structure 28, their opposite edges 36, are defined by a part of the circumference of the aperture part 24b. These edges 38 are arranged in the transverse direction with respect to the direction of extension of the element 22 and converge in the direction A ". The edges 38 of the contact parts 32 of the contact structure 30 are defined by another part of the circumference of a further part 24c of the aperture 24. These edges too 38 are arranged in the transverse direction with respect to the direction of extension of the element 22 and converge in the direction "A".
Figur 3 zeigt isolierte Adern 48 mit von Isolierung 52 umgebenen Innenleitern 50. Die Partien 24a, 24b der Apertur 24 sind ausreichend groß, so daß sie jeweilige dieser Adern 48, wie gezeigt, so aufnehmen können, daß sich diese Adern normal zu der Ebene der zentralen Partie 26 des Elements 22 erstrecken. Nachdem sich die Adern, wie in Figur 3 gezeigt, in Position befinden, können sie in der der Richtung "A" entgegengesetzten Richtung bewegt werden, so daß sie in die Kanäle 42 gelangen, um die Isolierung 52 zu schneiden und eine elektrische Verbindung zwischen den Kontaktkanten 32c der Kontaktpartien 32 und den Leitern 50 ähnlich wie in Figur 1 beschrieben herzustellen. Um die Wirksamkeit der Funktion weiter zu verbessern, weist das Element 22 an seinen gegenüberliegenden Langskanten Flansche 46, 47 auf. Diese sind, wie gezeigt, bezüglich der Ebene einer zentralen Partie 26 des Elements 22 entgegengesetzt ausgerichtet, so daß sich einer auf jeder der beiden Seiten dieser Ebene befindet. Sie erstrecken sich außerdem, wie gezeigt, bei Betrachtung in einem Schnitt quer zur Erstreckungsrichtung des Elements 22 unter einem Winkel von ungefähr 45° zu der Ebene der zentralen Partie 26. Die Flansche 46, 47 verstarken das Element 22 und erleichtern eine wirksame Verbindung mit den Adern.Figure 3 shows insulated wires 48 with inner conductors 50 surrounded by insulation 52. The portions 24a, 24b of the aperture 24 are sufficiently large that they can accommodate each of these wires 48, as shown, such that these wires are normal to the plane of the extend central portion 26 of the element 22. After the cores are in position as shown in Figure 3, they can be moved in the opposite direction of "A" direction so that they enter channels 42 to cut insulation 52 and establish an electrical connection between the To produce contact edges 32c of the contact portions 32 and the conductors 50 similar to that described in Figure 1. In order to further improve the effectiveness of the function, the element 22 has flanges 46, 47 on its opposite long edges. As shown, these are oppositely oriented with respect to the plane of a central portion 26 of element 22 so that one is on either side of that plane. They also extend, as shown, when viewed in a section transverse to the direction of extension of element 22 at an angle of approximately 45 ° to the plane of FIG central part 26. The flanges 46, 47 reinforce the element 22 and facilitate an effective connection with the veins.
Wie in Figur 6 gezeigt, kann der Kontakt 20 zur Verwendung in Anwendungen, wie sie beispielsweise m der erwähnten australischen Patentschrift beschrieben sind, wo eine Verbindung mit anderen Schaltungselementen erforderlich ist, durch eine geeignete Endpartie 56 mit anderen Leitern, wie beispielsweise dem gezeigten Leiter 58, verbunden werden.As shown in FIG. 6, the contact 20 can be used through a suitable end portion 56 with other conductors, such as the shown conductor 58, for use in applications such as described in the aforementioned Australian patent where connection to other circuit elements is required , get connected.
Ebenfalls können, wie in Figur 7 gezeigt, gleitende Trager 60 an dem Kontaktelement 20 angebracht sein. In dem Fall von Figur 7 liegen zwei derartige Trager 60 vor, wobei jeder Apertur 24 jeweils einer zugeordnet ist. Jeder Trager 60 ist als ein Korper 62 gebildet, der aus elektrisch isolierendem Material mit einem sich in Längsrichtung dadurch erstreckenden Schlitz 64 gebildet ist, der das Element 22 für eine gleitende Bewegung der Trager 60 dort entlang passend und gleitend aufnimmt. Jeder Trager 60 weist zwei Offnungen 66, 68 auf, wobei sich diese allgemein parallel zu den Flanschen 46, 47 und somit unter einem Winkel von 45° zu der zentralen Partie 26 des Kontaktelements 22 erstrecken. Jeder Trager 60 und die Offnungen 66, 68 dort hindurch sind so angeordnet, daß die Offnungen 66, 68 m jeweiligen ersten Positionen der Trager n Ausrichtung auf die Partien 24a, 24b der jeweiligen Aperturen 24 m dem Element 22 angeordnet sind. In diesem Zustand können Adern in die Trager eingeführt werden, so daß sie sich durch die jeweiligen Offnungen 66, 68 und in die Partien 24a, 24b der Aperturen erstrecken. Danach werden die Adern durch eine Gleitbewegung der Trager 60 in der bei Betrachtung in Figur 7 der Richtung "A" entgegengesetzten Richtung zwischen die Kanäle 42 gedruckt, um, wie beschrieben, eine elektrische Verbindung herzustellen.Also, as shown in FIG. 7, sliding supports 60 can be attached to the contact element 20. In the case of FIG. 7 there are two such carriers 60, each aperture 24 being assigned to one. Each carrier 60 is formed as a body 62 which is formed from electrically insulating material with a longitudinally extending slot 64 which matingly and slidably receives the member 22 for sliding movement of the carriers 60 therealong. Each carrier 60 has two openings 66, 68, these generally extending parallel to the flanges 46, 47 and thus at an angle of 45 ° to the central part 26 of the contact element 22. Each support 60 and the openings 66, 68 therethrough are arranged such that the openings 66, 68 m are arranged in the element 22 in the respective first positions of the supports n in alignment with the parts 24a, 24b of the respective apertures 24 m. In this state, veins can be inserted into the supports so that they extend through the respective openings 66, 68 and into the parts 24a, 24b of the apertures. Thereafter, the wires are printed between the channels 42 by sliding movement of the carriers 60 in the direction opposite the direction "A" as viewed in Figure 7 to establish an electrical connection as described.
Figur 9 zeigt eine Anordnung, in der mehrere Kontakte 20 in einem Gehäuse 70 enthalten sind, das jeweilige, den Tragern 60 zugeordnete Offnungen aufweist, wobei es, wie in Figur 7 gezeigt, für jeden Kontakt 20 zwei Trager 60 gibt. Das Gehäuse weist Schlitze 72 auf, so daß, wenn sich die Trager 60 in Positionen für die Aufnahme von Adern befinden (wie in Figur 9 gezeigt) , die Offnungen 68 der Trager an einem Ende der jeweiligen Schlitze 72 positioniert sind. Die Schlitze 72 sind ausreichend lang, so daß die Trager 60 bewegt werden können, um eine elektrische Verbindung, wie beschrieben, durch eine derartige Bewegung herzustellen, daß die andere Öffnung 66 von jedem dann an dem gegenüberliegenden Ende des jeweiligen Schlitzes 72 positioniert ist.Figure 9 shows an arrangement in which a plurality of contacts 20 are contained in a housing 70 which has respective openings assigned to the supports 60, wherein, as shown in FIG. 7, there are two supports 60 for each contact 20. The housing has slots 72 so that when the carriers 60 are in positions for receiving wires (as shown in Figure 9), the openings 68 of the carriers are positioned at one end of the respective slots 72. The slots 72 are sufficiently long so that the supports 60 can be moved to establish an electrical connection as described by movement such that the other opening 66 of each is then positioned at the opposite end of the respective slot 72.
Das Gehäuse 70 kann beispielsweise einen Teil einer Stromsteckdose bilden, wie in der australischen Patentanmeldung Nr. 90449/98 beschrieben.For example, housing 70 may form part of an electrical outlet as described in Australian Patent Application No. 90449/98.
