Description

Die Erfindung betrifft eine Kontaktklemme für ein isoliertes, mehradriges elektrisches Kabel, insbesondere ein formcodiertes Profilkabel nach dem Oberbegriff des Anspruchs 1.The invention relates to a contact terminal for an insulated, multi-core electrical cable, in particular a shape-coded Profile cable according to the preamble of claim 1.

Formcodierte Profilkabel werden als Busleitung oder Energieleitung in Maschinensteuerungen eingesetzt, um Aktoren (Magnetventile und dgl.) wie Sensoren mit einem Interface zu verbinden. Diese Profilkabel müssen neben hohen mechanischen Belastungen auch widerstandsfähig gegen Schmutz, Säure, Lösungsmittel und dgl. sein, weshalb eine entsprechende widerstandsfähige Isolierung gewählt ist. Diese meist als Flachkabel ausgeführten Profilkabel sind aufgrund ihrer widerstandsfähigen Isolierung schlecht zu kontaktieren, weshalb die Piercing-Technik verwendet wird. Bei dieser Technik wird das Profilkabel auf Kontaktmesser aufgedrückt, welche die Isolierung durchschneiden und in die Kupferseele der Leitungsadern eindringen, um eine elektrische Kontaktierung herzustellen.Shape coded profile cables are called bus or power line used in machine controls to actuators (solenoid valves and the like.) How to connect sensors with an interface. These profile cables must in addition to high mechanical loads also resistant to dirt, acid, solvents and Like., Which is why a corresponding resistant insulation is selected. These are usually designed as flat cables Profile cables are due to their resistant insulation bad to contact, which is why the piercing technique used becomes. In this technique, the profile cable is on contact blades imprinted, which cut through the insulation and into the Copper core of the wires penetrate to an electric Establish contact.

Die US-A 3 874 762 offenbart einen Stecker, der über Piercing Kontakte mit einer mehradrigen Energieleitung zu verbinden ist. US-A-3 874 762 discloses a plug piercing Connect contacts with a multi-core power line.

Die Energieleitung ist im Querschnitt symmetrisch aufgebaut, so daß sie in verschiedenen Drehlagen in eine mit Piercing-Kontakten versehene Aufnahme des Steckers einsetzbar ist. Durch Schließen der Aufnahme mit einem Deckel werden die Piercing-Kontakte in die Kupferadern der Energieleitung hereingedrückt.The power line is symmetrical in cross section, so that they are in different rotational positions in one with piercing contacts provided receptacle of the plug can be used. By Close the recording with a lid, the piercing contacts pushed into the copper wires of the power line.

Die EP-A 0 726 623 zeigt einen Piercing-Anschluß, bei dem ein im Querschnitt asymmetrisches Kabel lagerichtig in eine Aufnahme eines Anschlußgehäuses einzulegen und zu fixieren ist. Durch im Gehäuse vorgesehene Schlitze werden Piercing-Kontakte gesteckt und durch Aufschrauben eines Deckels in die Kupferadern der Leitung getrieben. Die Piercing-Kontakte selbst stellen die elektrisch leitende Verbindung zu einem Abgriff her. Dabei muß dafür Sorge getragen werden, daß eine polrichtige Kontaktierung erfolgt, um die elektrische Funktionsfähigkeit sicherzustellen. In der Praxis hat sich gezeigt, daß bei der Installation Profilkabel mitunter lageverkehrt an einem Piercing-Anschluß ankommen; um eine lagerichtige Zuführung des Kabels zu erreichen, mußten meist zusätzliche Schleifen gelegt werden, was umständlich ist, Installationsraum verbraucht und bei einer Fehlersuche sehr störend ist.EP-A 0 726 623 shows a piercing connection in which an im Cross-section of asymmetric cable in the correct position in a receptacle a terminal housing insert and fix is. By im Housing slots provided piercing contacts are inserted and by screwing a lid into the copper wires of Driven by leadership. The piercing contacts themselves represent the electrically conductive connection to a tap ago. It must Care must be taken that a correct polarity contact done to ensure the electrical functionality. In practice it has been shown that during installation Profile cable sometimes reversed at a piercing connection Arrive; to a correct position supply of the cable to reach, usually additional loops had to be laid, which is cumbersome, installation space consumed and at one Troubleshooting is very disturbing.

Der Erfindung liegt die Aufgabe zugrunde, eine Piercing-Kontaktklemme anzugeben, bei der unabhängig von der Lage des anzuschließenden Kabels ein polrichtiger Anschluß gewährleistet ist.The invention is based on the object, a piercing contact terminal specify, regardless of the location of the connected Cable a polar connection is guaranteed.

Je nach der Lage des zugeführten Kabels wird somit entweder der eine äußere Kontaktpin oder der andere äußere Kontaktpin zur Kontaktierung der Ader im zugeführten Kabel genutzt, wobei der jeweils andere äußere Kontaktpin blind bleibt.Depending on the position of the supplied cable is thus either the an outer contact pin or the other outer contact pin to Contacting the wire used in the supplied cable, the each other outer contact pin remains blind.

Bevorzugt ist die Anordnung so getroffen, daß eine mittlere Kontaktreihe in einer Ebene liegt, die die Aufnahme in Längsrichtung des Kabels symmetrisch teilt. Die Lageveränderung des Kabels innerhalb der Aufnahme entspricht somit jeweils dem Mittenabstand der Leitungsadern im Kabel, wobei die mittlere Kontaktreihe unabhängig von der Lage des Kabels in der Aufnahme immer die gleiche Ader kontaktiert.Preferably, the arrangement is such that a middle Contact row lies in a plane, which is the longitudinal recording the cable splits symmetrically. The change in position of the Cable within the receptacle thus corresponds to the respective Center distance of the wires in the cable, the middle Contact row regardless of the location of the cable in the receptacle always contacted the same vein.

Bevorzugt ist das Kabel ein zweiadriges Kabel, dem drei quer zur Längsrichtung des Kabels nebeneinander liegende Kontaktpins zugeordnet sind. Das Kabel wird dabei in der einen Lage an dem einen Seitenrand der Aufnahme liegen und in der anderen Lage an dem anderen Seitenrand der Aufnahme, so daß das Kabel von der einen Lage in die andere Lage um den mittleren Kontaktpin um 180°C gedreht liegen kann.Preferably, the cable is a two-core cable, the three transverse to Associated longitudinal direction of the cable adjacent contact pins are. The cable will be in one position on the one side edge of the recording lie and in the other position the other side edge of the recording, so that the cable from the one layer to the other position around the middle contact pin 180 ° C can be rotated.

Die Kontaktpins sind bevorzugt als Kontaktmesser vorgesehen, deren jeweiliges Schneidblatt etwa in Längsrichtung des Kabels ausgerichtet liegt und die Seele der Leitungsader zentral einschneidet.The contact pins are preferably provided as a contact blade, their respective cutting blade approximately in the longitudinal direction of the cable is aligned and cuts the soul of the conductor vein central.

Um unabhängig von der Lage des Kabels der Aufnahme einen polrichtigen Anschluß der Kontaktklemme zu gewährleisten, sind die äußeren Kontaktpins elektrisch miteinander verbunden. Regardless of the location of the cable recording a polrichtigen To ensure connection of the contact terminal, are the outer contact pins electrically connected together.

Um auch den Anforderungen hoher Schutzklassen zu genügen, ist bevorzugt vorgesehen, das Paßstück als Dichtung auszubilden, wobei das Paßstück zweckmäßig das Kabel insbesondere vollständig umgreift. Das Paßstück selbst bildet somit eine das Kabel einschließende Dichtung, so daß der Kontaktbereich der Piercingmesser von der Umgebung sauber abgedichtet ist.To meet the requirements of high protection classes, is preferably provided to form the fitting as a seal, wherein the fitting appropriately the cable in particular completely embraces. The fitting itself thus forms a cable enclosing Seal so that the contact area of the piercing knife is sealed from the environment clean.

Das Profilkabel kann die Kontaktklemme durchlaufen, wobei die Kontaktklemme selbst als elektrischer Verbinder zwischen Endstücken von Profilkabeln oder parallel nebeneinander liegender Profilkabel genutzt werden kann. Auch kann mittels der erfindungsgemäßen Kontaktklemme ein Steckanschluß angebracht werden, wozu z.B. der Steckanschluß an dem einen oder anderen Klemmenteil angeordnet ist. Bevorzugt ist der Steckanschluß oder dgl. an dem Klemmenteil vorgesehen, der auch die Kontaktpins bzw. die Kontaktmesser trägt.The profile cable can pass through the contact terminal, wherein the Contact terminal itself as an electrical connector between end pieces of profile cables or parallel next to each other Profile cable can be used.
