Description

Die Erfindung betrifft eine Vorrichtung zur Befestigung von Klemmkontakten an elektrische Leiter mit einer aus zwei Spannbacken bestehenden Spanneinrichtung zur Erfassung der eingeführten isolierten Leiter, hinter der etwas abgesetzt zwei gegenphasig bewegbare Abisoliermesser an einem in Längsrichtung verschiebbaren Abisolierkopf angebracht sind, wobei oberhalb des Abisolierkopfes unmittelbar hinter den Spannbacken ein vertikal bewegbarer Prägeeinsatz und darunter ein Amboß angeordnet ist, dem über eine Transporteinrichtung in Streifen aufgeteilte Klemmkontakte zuführbar sind, wobei einer der Spannbacken vertikal bewegbar und der andere Spannbacken feststehend ausgebildet sind, und ein Sensor zur Auslösung des Klemmvorangs am Abisolierkopf befestigt ist, bei der der Prägeeinsatz und der ebenfalls vertikal bewegbare Amboß zweiteilig zur Klemmung von Isolations- und Leitungsklemmlappen der Klemmkontakte ausgebildet sind, und die Transporteinrichtung aus einer fest mit dem Amboß verbundenen Bandführung besteht, auf der das mit Klemmkontakten bestückte Trägerband quer horizontal an der Oberseite des Ambosses vorbei bewegbar ist, wobei an der Oberkante des Ambosses entlang ein Messer zum Abtrennen der Klemmkontakte vom Trägerband vorgesehen ist.The invention relates to a device for fastening clamping contacts to electrical conductors with a clamping device consisting of two clamping jaws for detecting the inserted insulated conductors, behind which two stripping knives movable in opposite phases are attached to a stripping head which can be displaced in the longitudinal direction, above the stripping head directly behind the Clamping jaws a vertically movable stamping insert and an anvil is arranged below it, to which clamping contacts divided into strips can be fed via a transport device, one of the clamping jaws being vertically movable and the other clamping jaw being fixed, and a sensor for triggering the clamping process being attached to the stripping head which the embossing insert and the also vertically movable anvil are formed in two parts for clamping insulation and cable clamping tabs of the clamping contacts, and the transport device from a fixed to the anvil connected tape guide, on which the carrier tape equipped with clamping contacts can be moved transversely horizontally past the top of the anvil, a knife for separating the clamping contacts from the carrier tape being provided along the upper edge of the anvil.

In der deutschen Patentschrift DE 35 28 203 C1 wird bereits eine solche Vorrichtung zur Befestigung von Klemmkontakten an elektrische Leiter beschrieben.Such a device for fastening terminal contacts to electrical conductors is already described in German Patent DE 35 28 203 C1.

Die bekannte Vorrichtung ist in Figur 1 dargestellt. Die Spannbacken sind an ihren benachbarten Seiten mit zwei Halböffnungen 3 und 4 versehen, die zusammen eine kreisförmige Öffnung ergeben, in die der zu behandelnde Leiter 5, der üblicherweise aus Litzendraht besteht, einführbar ist. Hinter den Spannbacken 1, 2 ist ein in Längsrichtung verfahrbarer Abisolierkopf 7 vorgesehen, der zwei in querhorizontaler Richtung bewegbare Abisoliermesser 6 enthält und hinter denen der Sensor 8 angeordnet ist. Im Ruhezustand oberhalb des Abisolierkopfes 7 und unmittelbar hinter den Spannbacken 1, 2 ist der Prägesatz 9 angeordnet, der aus zwei Teilen besteht, wobei in der Figur nur das Prägeteil für die abisolierte Leitung dargestellt ist, während das Prägeteil für die,die Isolation umfassenden Lappen, der Einfachheit halber nicht gezeigt ist. Dieses Teil hat die gleiche Form wie der Prägesatz 9, jedoch ist dieser Prägeeinsatz an seiner unteren Seite mit einer halbkreisförmigen Ausnehmung versehen. Unterhalb des Prägesatzes 9 ist der Amboß 12 angeordnet, der wiederum aus zwei Teilen besteht, wobei auch hier aus Übersichtlichkeitsgründen nur das mit dem Prägesatz 9 zusammenarbeitende Amboßteil 12 dargestellt ist. Der Amboß 12 ist nach oben verjüngt, wodurch er von dem wäscheklammerartig geformten Prägesatz 9 in Arbeitsstellung umgriffen werden kann. Der Amnboß 12 ist außerdem fest mit der Bandführung 13 verbunden und sowohl Amboß 12 bzw. Bandführung 13 und Prägesatz 9 sind in vertikaler Richtung bewegbar. Auf der Bandführung 13 wird das Trägerband 16 querhorizontal bewegt Dieses Trägerband enthält nebeneinander angeordnet eine Anzahl der Klemmkontakte 14, wobei das Trägerband 16 seitlich mit der oberen Amboßfläche fluchtend am Amboß vorbeigeführt wird, so daß jeweils ein Klemmkontakt 14 auf der oberen Amboßfläche zu liegen kommt.The known device is shown in Figure 1. The clamping jaws are provided on their adjacent sides with two half openings 3 and 4, which together result in a circular opening into which the conductor 5 to be treated, which usually consists of stranded wire, can be inserted. A stripping head 7 which can be moved in the longitudinal direction is provided behind the clamping jaws 1, 2 and contains two stripping knives 6 which can be moved in the transverse horizontal direction and behind which the sensor 8 is arranged. In the idle state above the stripping head 7 and immediately behind the clamping jaws 1, 2, the stamping set 9 is arranged, which consists of two parts, only the stamping part for the stripped line being shown in the figure, while the stamping part for the tabs comprising the insulation is not shown for the sake of simplicity. This part has the same shape as the stamping set 9, but this stamping insert is provided on its lower side with a semicircular recess. The anvil 12, which in turn consists of two parts, is arranged below the embossing set 9, with only the anvil part 12 cooperating with the embossing set 9 being shown here for reasons of clarity. The anvil 12 is after tapers at the top, so that it can be gripped by the clothespin-shaped embossing set 9 in the working position. The anvil 12 is also firmly connected to the tape guide 13 and both anvil 12 or tape guide 13 and embossing set 9 can be moved in the vertical direction. On the tape guide 13, the carrier tape 16 is moved transversely horizontally. This carrier tape contains a number of clamping contacts 14 arranged next to one another, the carrier tape 16 being guided laterally in alignment with the upper anvil surface past the anvil, so that a clamping contact 14 comes to rest on the upper anvil surface.

Der Ablauf des Crimpvorganges ist wie folgt: Die isolierte Leitung 5, die eine Litzenleitung sein kann, wird zwischen den fest eingebauten Spannbacken 2 und den beweglichen Spannbacken 1 eingeführt. Der Abisolierkopf 7 befindet sich dabei in der Position A. Beim Einführen des Leiter 5 berührt dieser den Sensor 8 im Abisolierkopf 7. Dadurch löst der Sensor den Arbeitszyklus des Strippercrimpers aus. Zunächst wird der Leiter mit dem beweglichen Spannbacken 1 gespannt. Das wesentliche dabei ist daß der Leiter 5 in dieser Lage bleibt und nicht wie bei bekannten Anordnungen schlagartig nach unten bewegt wird. Dieser Vorteil bietet eine gute Voraussetzung für eine automatische Verarbeitung von Einzellitzen.The sequence of the crimping process is as follows: The insulated line 5, which can be a stranded line, is inserted between the fixed jaws 2 and the movable jaws 1. The stripping head 7 is in position A. When the conductor 5 is inserted, it touches the sensor 8 in the stripping head 7. As a result, the sensor triggers the working cycle of the stripper crimper. First, the conductor is clamped with the movable jaw 1. The essential thing is that the conductor 5 remains in this position and is not suddenly moved downwards as in known arrangements. This advantage offers a good prerequisite for automatic processing of individual strands.

Die beiden Abisoliermesser 6 werden danach gleichmäßig zur Mitte hin bewegt und dringen mit ihren Schneiden in die Isolation ein, ohne die Metallseele des Leiters 5 zu verletzen. Der Abisolierkopf 7 fährt dann in die Position B und zieht dabei die Isolation vom Leiter 5 ab und wird abgesaugt. Danach öffnen die Abisoliermesser 6 und gehen in ihre Ausgangslage zurück.The two stripping knives 6 are then moved evenly towards the center and penetrate with their cutting edges into the insulation without damaging the metal core of the conductor 5. The stripping head 7 then moves to position B, pulling the insulation off the conductor 5 and being suctioned off. Then the stripping blades 6 open and return to their starting position.

Die Bandführung 13 und der Amboß 12, die eine Einheit bilden, fahren, nachdem der Abisolierkopf 7 in die Position B zurückgefahren ist und eine mechanische Verriegelung dadurch aufgehoben wurde, nach oben. Der Kontakt 14 wird dabei zum Leiter 5 und in die richtige Crimpposition gebrachtThe tape guide 13 and the anvil 12, which form a unit, move upwards after the stripping head 7 has been moved back to the position B and a mechanical lock has been released thereby. The contact 14 is brought to the conductor 5 and in the correct crimping position

Mit zeitlicher Verzögerung bewegt sich der Prägeeinsatz 9 nach unten und klemmt den Kontakt 14 so an den Leiter 5 an, daß die hinteren beiden Kontaktlappen 10 die Isolation des Leiters 5 und die vorderen Kontaktlappen 11 die Seele des Leiters 5 umfassen. In der letzten Phase des Crimpvoganges trennt das zwischen Kontakt 14 und Leiter 5 befindliche Messer 15 den Klemmkontakt 14 vom Trägerband 16. Das Trägerband 16 selbst wird in einem nicht dargestellten Afalltrenner in Stücke geschnitten.With a time delay, the embossing insert 9 moves downward and clamps the contact 14 onto the conductor 5 in such a way that the rear two contact tabs 10 encompass the insulation of the conductor 5 and the front contact tab 11 surround the core of the conductor 5. In the last phase of the crimping process, the knife 15 located between contact 14 and conductor 5 separates the clamping contact 14 from the carrier tape 16. The carrier tape 16 itself is cut into pieces in a fall separator, not shown.

Anschließend fährt der Amboß 12 zusammen mit der Bandführung 13 und dem Prägesatz 9 in ihre Ausgangsstellung in die Positionen C und D zurück.Then the anvil 12 moves back together with the tape guide 13 and the embossing set 9 in their starting position in positions C and D.

Der bewegliche Spannbacken 1 öffnet und läßt jetzt ein genügend großes Fenster frei, um den gecrimpten Kontakt aus dem Strippercrimper entnehmen zu können.The movable jaw 1 opens and now leaves a window large enough to be able to remove the crimped contact from the stripper crimper.

Anschließend fährt der bewegliche Spannbacken 1 bis auf einen geringen Spalt an den festen Spannbacken 2 heran. Gleichzeitig fährt der Abisolierkopf 7 in die Startposition A. Der Strippercrimper ist für den nächsten Arbeitszyklus bereitThen the movable jaw 1 moves up to a small gap on the fixed jaws 2. At the same time, the stripping head 7 moves to the start position A. The stripper crimper is ready for the next work cycle

Aufgabe der vorliegenden Erfindung ist, die bekannte Vorrichtung so auszubilden, daß, unter Beibehaltung des prinzipiellen Verfahrensablaufes, das gleichzeitige Abisolieren von mehr als einem elektrischen Leiter gleichzeitig mit anschließendem Befestigen nur eines gemeinsamen Klemmkontaktes möglich ist.The object of the present invention is to design the known device in such a way that, while maintaining the basic process sequence, the simultaneous stripping of more than one electrical conductor is possible at the same time with subsequent fastening of only one common clamping contact.

Zur Lösung dieser Aufgabe wird die Vorrichtung erfindungsgemäß derart ausgebildet, daß die Spannbacken der Spanneinrichtung der Zahl der Leiter entsprechende Halböffnungen für die Aufnahme mehrerer nebeneinander liegender Leiter aufweisen, und daß die Abisoliermesser mit der Zahl der Leiter entsprechenden halbkreisförmigen Schnittkanten versehen und zueinander vertikal bewegbar ausgebidlet sind, und daß der Prägesatz für mehrere Leiter gemeinsam vorgesehen ist.To achieve this object, the device is designed according to the invention in such a way that the clamping jaws of the clamping device have half openings corresponding to the number of conductors for receiving several conductors lying next to one another, and that the stripping knives are provided with semicircular cutting edges corresponding to the number of conductors and are designed to be vertically movable with respect to one another , and that the embossing set is intended for several conductors together.

Durch diese Maßnahmen wird erreicht, daß mehrere Leiter oder Litzen in einem Arbeitsgang abisolier und mit einem Klemmkontakt versehen werden können.These measures ensure that several conductors or strands can be stripped in one operation and provided with a terminal contact.

Anhand des Ausführungsbeispiels nach der Figur 2 wird die Erfindung näher erläutertThe invention is explained in more detail using the exemplary embodiment according to FIG

Es ist eine Anordnung mit zwei Leitern dargestellt, wobei jedoch die Zahl der Leiter auch größer sein kann. Die Leiter werden durch die Spannbacken 1, 2 gehalten. Der Abisolierkopf 7a ist in Längsrichtung verfahrbar und enthält ein Sensorteil 8a, 8b, das entweder nur einen Sensor enthält, was jedoch den Nachteil mit sich bringt, daß bei unterschiedlich langen Leitungen der Abisoliervorgang bereits bei der ersten Berührung eingeleitet wird, so daß die Leitungen nach dem Crimpvorgang unterschiedlich lang sind. Dieser Nachteil wird dadurch vermieden, daß man jeder Leitung einen Sensor zuordnet, und erst wenn alle Sensoren betätigt sind, der Abisoliervorgang beginnt.An arrangement with two conductors is shown, although the number of conductors can also be larger. The ladder is held by the jaws 1, 2. The stripping head 7a can be moved in the longitudinal direction and contains a sensor part 8a, 8b, which either contains only one sensor, but this has the disadvantage that, in the case of lines of different lengths, the stripping process is initiated at the first touch, so that the lines after the crimping process are of different lengths. This disadvantage is avoided by assigning a sensor to each line and only when all the sensors are actuated does the stripping process begin.

Die Abisoliermesser 6a, sind an der Vorderseite des Abisolierkopfes angeordnet und im Gegensatz zur bekannten Anordnung vertikal aufeinander zubewegbar, wobei die Schnittkanten 17 entsprechend an die Form der Leitungen angepaßt sind. In der Figur 2 ist lediglich das untere Messer dargestellt, um einen besseren Einblick in das Innere des Abisolierkopfes 7 zu gestatten. Das obere Messer ist entsprechend dem unteren ausgebildet Beide Messer wobei in der Figur nur das Prägeteil für die abisolierte Leitung dargestellt ist, während das Prägeteil für die die Isolation umfassenden Lappen der Einfachheit halber nicht gezeigt ist. Dieses Teil hat die gleiche Form wie der Prägeeinsatz 9, jedoch ist dieser Prägeeinsatz an seiner unteren Seite mit einer halbkreisförmigen Ausnehmung versehen. Unterhalb des Prägeeinsatzes 9 ist wiederum der Amboß 12 angeordnet, der ebenfalls aus zwei Teilen besteht, wobei auch hier aus Übersichtlichkeitsgründen nur das mit dem Prägeeinsatz 9 zusammenarbeitende Amboßteil 12 dargestellt ist. Auch hier ist der Amboß 12 wieder nach oben verjüngt, wodurch er von dem wäscheklammerartig geformten Prägeeinsatz 9 in Arbeitsstellung umgriffen werden kann. Auf der Bandführung 13 wird das Trägerband 16 so weit quer horizontal bewegt, bis der Klemmkontakt 14 auf den Amboß 12 unmittelbar unterhalb der beiden Leitungen 5a, 5b aufliegt Anschließend fährt der Prägeeinsatz 9 nach unten und bewerkstelligt den Crimpvorgang. Dabei werden beide Leitungen nur mit einem Klemmkontakt verbunden.The stripping knives 6a are arranged on the front of the stripping head and, in contrast to the known arrangement, can be moved vertically towards one another, the cutting edges 17 being correspondingly adapted to the shape of the lines. In Figure 2, only the lower knife is shown to allow a better view of the inside of the stripping head 7. The upper knife is designed according to the lower one. Both knives only the stamped part for the stripped line is shown in the figure, while the stamped part for the tabs comprising the insulation is not shown for the sake of simplicity. This part has the same shape as the stamping insert 9, but this stamping insert is provided on its lower side with a semicircular recess. The anvil 12, which likewise consists of two parts, is arranged below the embossing insert 9, again only the anvil part 12 cooperating with the embossing insert 9 being shown here for reasons of clarity. Here, too, the anvil 12 is again tapered upwards, as a result of which the embossing insert 9, which is shaped like a clothespin, can grip it in the working position. On the tape guide 13, the carrier tape 16 is moved horizontally until the clamping contact 14 rests on the anvil 12 immediately below the two lines 5a, 5b. The embossing insert 9 then moves downward and carries out the crimping process. Both lines are only connected with one terminal contact.
