Definitions

  • the present disclosure relates to an apparatus, a method and a system for crimping or inverse crimping.
  • Inverse crimping here means that the crimp anvil, together with the crimp contact part supported on the crimp anvil or guided in the separating knife, is moved towards a stationary crimper instead of the usual movement of the crimper on a stationary crimping anvil with crimp contact part supported on the crimping anvil or guided in the separating knife.
  • all crimp contact parts are applied to the cores (individual cables) of a multi-core cable with the same orientation. For example, in the case of a four-wire line, two crimp contact parts are crimped onto the corresponding wires from above. Then the crimp contact parts are rotated by appropriate devices (or manually) into the desired positions with which the plug housing is to be populated. This subsequent turning of the individual wires or crimp contact parts is the more difficult the shorter the stripping length of the jacket of the multi-core cable.
  • the cables and the others are alternatively inserted into the crimping device automatically or by hand, rotated about their longitudinal axis, or the entire crimping device is rotated (in the example above, first the upper wires and then after a 180 ° rotation of the cable around them Longitudinal axis crimped the lower wires).
  • the object of the present disclosure is to specify an apparatus, a method and a system for inverse crimping, with which the formation of crimped multi-core lines with different orientations of the crimp contact parts can be simplified and improved.
  • the crimping device described in this disclosure differs from a standard crimping device in that the crimping boss is mounted on the moving part of the crimping device instead of the fixed part and the crimper is mounted on the fixed part of the crimping device instead of the moving part.
  • the crimping anvil and the crimper are thus mounted inversely with respect to a conventional crimping device.
  • the movement in or with which the crimping process is carried out is still from top to bottom.
  • the crimp contact parts are also rotated by 180 ° with respect to their longitudinal axis (inverse), i.e. opened downwards, fed or inserted into the crimping device.
  • a crimp contact part is preferably a metallic, preferably plastically deformable, at least partially electrically conductive component.
  • the crimp contact part has a crimp area in its longitudinal direction on one side and a contact area on the other side.
  • the crimping area is connected during the crimping by plastic deformation by means of the crimping device with a cable / conductor / cable end or a wire, which is or is optionally provided with a wire end sleeve, preferably firmly or positively connected.
  • the contact area preferably forms a plug, a pin or a Socket out. After crimping, the contact area can be mounted in a corresponding housing of a multi-pin plug.
  • the crimp contact part does not have a contact area in the above sense but is an open profile in the uncrimped state (tubular or V-shaped or U-shaped), which is completely not overlapping, completely overlapping or not completely closed when crimping around the wire .
  • the crimp contact part in the crimped state can preferably form a support sleeve, for example for surrounding a braided jacket.
  • Each crimp contact part is preferably crimped with a single line or a single cable or a single wire.
  • the crimp contact parts mentioned here are preferably not used for the direct connection of two wires within the area to be reshaped.
  • the crimp contact parts are preferably fed to the crimping device by means of a feed belt.
  • Each crimp contact part is preferably held at least on one side on the feed belt, the connection between the feed belt and the crimp contact part being such that a predetermined breaking point enables the crimp contact part to be easily separated or sheared from the feed belt without substantial damage or deformation of the crimp contact part.
  • the feed belt is preferably metallic, but can also be made of plastic.
  • the crimp contact part held on the feed belt is already preformed. In the case of a crimp contact part with a crimp area and a contact area, the contact area is preferably already completely formed, so that no further shaping is necessary for later use as a plug or socket, for example.
  • the crimp area is preferably also preformed, so that only a final and slight deformation is required for connection to the wire, but at the same time insertion of the wire is not unnecessarily hindered.
  • the feed belt guide device that is preferably provided is preferably provided as a guide slot in the severing knife.
  • the severing knife or the guide slot formed therein thus serves to guide the feed belt.
  • the guide slot is designed such that only the feed belt is guided in it and the crimp contact part held on the feed belt protrudes therefrom.
  • the crimping anvil and the severing knife are slidably mounted on each other.
  • the crimp contact part projects in such a way that a support surface of the crimp anvil is in contact with the projecting crimp contact part or comes into contact in a sliding relative movement between the crimp contact part and the crimp anvil can.
  • the crimp contact part is moved together with the crimp anvil towards the crimper while it is held on the feed belt which is guided in the guide slot.
  • the crimp contact part supported on the supporting surface of the crimp anvil is moved further together with the crimp anvil in the direction of the crimper, while the cutting knife remains stationary.
  • the crimp contact part is sheared off by the edge of the support surface facing the severing knife or a shearing edge provided on the crimping boss near the supporting surface and the edge of the severing knife facing the crimping boss.
  • opened downwards means that the regions of the crimp contact part to be formed or reshaped are arranged below the regions not to be reshaped or formed, and / or that the wire to be crimped with the crimp contact part is inserted from bottom to top.
  • the claimed crimping device which is only slightly modified compared to conventional crimping devices, enables inverse crimping, ie crimping contact parts rotated by 180 ° to the standard crimping device.
  • a first wire of a multi-core line in the standard crimping device can thus have a first crimp contact part and a second wire of the multi-wire line in the inverse
  • the crimping device can be provided with a crimp contact part which is rotated through 180 ° with respect to the first crimp contact part, without the multi-core line having to be rotated about its longitudinal axis between the crimping processes.
  • the multi-core cable can therefore be continuously clamped or clamped, reducing the processing time is reduced and a high position and position correctness of the multi-core cables to the crimping device or the crimp contact parts is made possible.
  • the crimping process is preferably at least the process in which the wire is firmly connected to the wire by reshaping the crimp contact part or the crimp contact part is firmly connected to the wire by reshaping the same.
  • the crimping anvil is preferably the tool that supports the crimp contact part at least from above during the crimping process.
  • the crimp anvil is preferably not used directly for reshaping the regions of the crimp contact part to be reshaped, in particular the crimp contact parts to be crimped are preferably not opened in the direction of the crimp anvil.
  • the crimper is designed to shape the regions (or at least a large part thereof) of the crimp contact part supported on the crimp anvil in the crimping process in a relative movement between the crimp anvil and the crimper.
  • the crimp contact parts to be crimped are preferably opened in the direction of the crimper. In some embodiments, it is not excluded that regions of the crimp contact part are also deformed by the crimping boss. If crimp contact parts are used which are already "closed” in the initial state, the crimper is arranged on the side on which the overlap of the regions to be reshaped to one another is enlarged or changed in the crimping process.

  • the base 32 likewise has a stop 26 in the upper region, here horizontally offset from the crimper region, the function of which will be described later.
  • a crimp anvil 16 is provided vertically above the crimper 18.
  • the crimping anvil 16 is held movably in the vertical direction by means of a drive unit 36.
  • the crimping anvil 16 has a support area (support surface) 38, which is not shown in detail.

At least one crimp contact part itself (ie not the feed belt) held on the feed belt projects from the guide slot on the open side of the guide slot into the area between the crimping boss and the crimper (overlap area). So there is only the feed belt in the guide slot and only the crimp contact part between the crimping boss and the crimper.
  • a wire insertion opening 48 is further provided in the projecting area of the separating knife 22.

Furthermore, a crimp contact part 12 has already been fed by means of the feed belt 24 to a position between the crimping boss 16, in particular the support region 38, and the crimper 18, in particular the crimper region 34.

Das Inverscrimpen bedeutet hier, dass der Crimpamboss zusammen mit dem am Crimpamboss abgestützten bzw. im Abtrennmesser geführten Crimpkontaktteil auf einen ortsfesten Crimper zubewegt wird, statt der üblichen Bewegung des Crimpers auf einen ortsfesten Crimpamboss mit am Crimpamboss abgestützten bzw. im Abtrennmesser geführten Crimpkontaktteil.The present disclosure relates to an apparatus, a method and a system for crimping or inverse crimping. Inverse crimping here means that the crimp anvil, together with the crimp contact part supported on the crimp anvil or guided in the separating knife, is moved towards a stationary crimper instead of the usual movement of the crimper on a stationary crimping anvil with crimp contact part supported on the crimping anvil or guided in the separating knife.

Beim Crimpen von Crimpkontaktteilen an mehradrigen Leitungen werden gewöhnlicher Weise alle Crimpkontaktteile in der sogenannten Standard-Crimpgeometrie von einer Seite (von oben) erzeugt (siehe Fig. 5B). Bei bestimmten Steckertypen kann es nunmehr erforderlich sein, die Crimpkontaktteile an den Einzeladern zueinander entsprechend einer vorbestimmten Orientierung zu crimpen. Beispielsweise sollen bei einer 4-adrigen Leitung, die mit B-Crimpkontaktteilen zu versehen ist, die zwei oberen der B-Crimpkontaktteile im geöffneten Ausgangszustand nach oben geöffnet sein und die unteren zwei der B-Crimpkontaktteile im geöffneten Ausgangszustand nach unten geöffnet sein (horizontale Symmetrielinie).When crimping crimp contact parts on multi-core cables, all crimp contact parts in the so-called standard crimp geometry are usually produced from one side (from above) (see Figure 5B ). With certain connector types, it may now be necessary to crimp the crimp contact parts on the individual wires to one another in accordance with a predetermined orientation. For example, in the case of a 4-wire line which is to be provided with B crimp contact parts, the two upper ones of the B crimp contact parts are to be opened upwards in the open initial state and the lower two of the B crimp contact parts are to be open downwards in the open initial state (horizontal line of symmetry ).

In der Regel werden hierfür alle Crimpkontaktteile mit der gleichen Orientierung auf die Adern (einzelnen Kabel) einer mehradrigen Leitung aufgebracht. Beispielsweise werden hierbei bei einer vieradrigen Leitung zwei Crimpkontaktteile von oben auf die entsprechenden Adern aufgecrimpt. Anschließend werden die Crimpkontaktteile durch entsprechende Vorrichtungen (oder manuell) in die gewünschten Positionen gedreht, mit der die Bestückung der Steckergehäuse stattfinden soll. Dieses nachträgliche Drehen der einzelnen Adern bzw. Crimpkontaktteile ist umso schwieriger, je kürzer die Abmantellänge des Mantels der mehradrigen Leitung ist. Um diese Schwierigkeit zu umgehen, werden alternativ die Leitungen samt Andern automatisiert oder in Handarbeit um ihre Längsachse gedreht in die Crimpvorrichtung eingelegt oder die gesamte Crimpvorrichtung gedreht (im obigen Beispiel paarweise zuerst die oberen Adern und anschließend nach einer 180°-Drehung der Leitung um ihre Längsachse die unteren Adern gecrimpt).As a rule, all crimp contact parts are applied to the cores (individual cables) of a multi-core cable with the same orientation. For example, in the case of a four-wire line, two crimp contact parts are crimped onto the corresponding wires from above. Then the crimp contact parts are rotated by appropriate devices (or manually) into the desired positions with which the plug housing is to be populated. This subsequent turning of the individual wires or crimp contact parts is the more difficult the shorter the stripping length of the jacket of the multi-core cable. In order to avoid this difficulty, the cables and the others are alternatively inserted into the crimping device automatically or by hand, rotated about their longitudinal axis, or the entire crimping device is rotated (in the example above, first the upper wires and then after a 180 ° rotation of the cable around them Longitudinal axis crimped the lower wires).

Die WO 2008/087938 A1 , die US 3,685,148 A , die FR 1.395.498 A und die US 3,018,816 A offenbaren im Stand der Technik bekannte Crimpvorrichtungen.The WO 2008/087938 A1 , the US 3,685,148 A , the FR 1,395,498 A and the US 3,018,816 A disclose crimping devices known in the art.

Aufgabe der vorliegenden Offenbarung ist es, eine Vorrichtung, ein Verfahren und ein System zum Inverscrimpen anzugeben, mit der bzw. dem das Ausbilden von gecrimpten mehradrigen Leitungen mit verschiedenen Orientierungen der Crimpkontaktteile vereinfacht und verbessert werden kann.The object of the present disclosure is to specify an apparatus, a method and a system for inverse crimping, with which the formation of crimped multi-core lines with different orientations of the crimp contact parts can be simplified and improved.

Diese Aufgabe wird gelöst mit einer Vorrichtung nach Anspruch 1, einem System nach Anspruch 10 und einem Verfahren nach Anspruch 11. Weiterbildungen sind in den abhängigen Ansprüchen angegeben.This object is achieved with a device according to claim 1, a system according to claim 10 and a method according to claim 11. Further developments are specified in the dependent claims.

Die in dieser Offenbarung beschriebene Crimpvorrichtung unterscheidet sich von einer Standard-Crimpvorrichtung dadurch, dass der Crimpamboss statt an dem ortsfesten Teil an dem beweglichen Teil der Crimpvorrichtung und der Crimper statt an dem beweglichen Teil an dem ortsfesten Teil der Crimpvorrichtung montiert ist. Der Crimpamboss und der Crimper sind somit invers in Bezug auf eine herkömmliche Crimpvorrichtung montiert. Die Bewegung, in bzw. mit der der Crimpvorgang durchgeführt wird, ist nach wie vor von oben nach unten. Entsprechend der inversen Anordnung des Crimpamboss und des Crimpers werden auch die Crimpkontaktteile bezüglich ihrer Längsachse um 180° gedreht (invers), d.h. nach unten geöffnet, zugeführt bzw. in die Crimpvorrichtung eingelegt. D.h. sie werden so in die Crimpvorrichtung zugeführt bzw. eingelegt, dass sie im geöffneten Ausgangszustand nach unten hin geöffnet sind. Somit müssen auch die jeweiligen Adern (Leitungen), auf die die Crimpkontaktteile zu crimpen sind, unterhalb statt oberhalb des Crimpkontaktteils (invers) zugeführt bzw. in die Crimpvorrichtung eingelegt werden.The crimping device described in this disclosure differs from a standard crimping device in that the crimping boss is mounted on the moving part of the crimping device instead of the fixed part and the crimper is mounted on the fixed part of the crimping device instead of the moving part. The crimping anvil and the crimper are thus mounted inversely with respect to a conventional crimping device. The movement in or with which the crimping process is carried out is still from top to bottom. In accordance with the inverse arrangement of the crimp anvil and the crimp, the crimp contact parts are also rotated by 180 ° with respect to their longitudinal axis (inverse), i.e. opened downwards, fed or inserted into the crimping device. I.e. they are fed or inserted into the crimping device in such a way that they are open towards the bottom in the open initial state. The respective wires (lines) to which the crimp contact parts are to be crimped must therefore also be fed in below or instead of above the crimp contact part (inversely) or inserted into the crimping device.

In der vorliegenden Offenbarung ist ein Crimpkontaktteil bevorzugt ein metallisches, bevorzugt plastisch verformbares, wenigstens teilweise elektrisch leitendes Bauteil.In the present disclosure, a crimp contact part is preferably a metallic, preferably plastically deformable, at least partially electrically conductive component.

In einer bevorzugten Ausführungsform weist das Crimpkontaktteil in seiner Längsrichtung auf der einen Seite einen Crimpbereich und auf der anderen Seite einem Kontaktbereich auf. Der Crimpbereich wird während dem Crimpen durch plastische Umformung mittels der Crimpvorrichtung mit einem Kabel/Leiter/Kabelende oder einer Ader, welches bzw. welche gegebenenfalls mit einer Aderendhülse versehen ist, verbunden, bevorzugt fest bzw. formschlüssig verbunden. Der Kontaktbereich bildet bevorzugt einen Stecker, einen Stift oder eine Buchse aus. Der Kontaktbereich kann nach dem Crimpen in ein entsprechendes Gehäuse eines mehrpoligen Steckers montiert werden.In a preferred embodiment, the crimp contact part has a crimp area in its longitudinal direction on one side and a contact area on the other side. The crimping area is connected during the crimping by plastic deformation by means of the crimping device with a cable / conductor / cable end or a wire, which is or is optionally provided with a wire end sleeve, preferably firmly or positively connected. The contact area preferably forms a plug, a pin or a Socket out. After crimping, the contact area can be mounted in a corresponding housing of a multi-pin plug.

In einer anderen bevorzugten Ausführungsform weist das Crimpkontaktteil keinen Kontaktbereich im obigen Sinne auf sondern ist im ungecrimpten Zustand ein geöffnetes Profil (rohrförmig oder V- oder U-förmig), welches beim Crimpen um die Ader vollständig nicht überlappend, vollständig überlappend oder nicht vollständig geschlossen wird. In diesem Fall kann das Crimpkontaktteil im gecrimpten Zustand vorzugsweise eine Stützhülse, beispielsweise zum Umgeben eines Mantelgeflechts, bilden.In another preferred embodiment, the crimp contact part does not have a contact area in the above sense but is an open profile in the uncrimped state (tubular or V-shaped or U-shaped), which is completely not overlapping, completely overlapping or not completely closed when crimping around the wire . In this case, the crimp contact part in the crimped state can preferably form a support sleeve, for example for surrounding a braided jacket.

Bevorzugt wird jedes Crimpkontaktteil mit einer einzigen Leitung oder einem einzelnen Kabel oder einer einzelnen Ader vercrimpt. Die hier genannten Crimpkontaktteile dienen bevorzugt nicht zur unmittelbaren Verbindung zweier Adern innerhalb des umzuformenden Bereichs.Each crimp contact part is preferably crimped with a single line or a single cable or a single wire. The crimp contact parts mentioned here are preferably not used for the direct connection of two wires within the area to be reshaped.

Die Crimpkontaktteile werden bevorzugt mittels eines Zuführbands zu der Crimpvorrichtung zugeführt. Bevorzugt ist jedes Crimpkontaktteil mindestens einseitig an dem Zuführband gehalten, wobei die Verbindung zwischen dem Zuführband und dem Crimpkontaktteil dergestalt ist, dass mittels einer Sollbruchstelle eine leichte Abtrennung oder Abscherung des Crimpkontaktteils von dem Zuführband ohne wesentliche Beschädigung oder Verformung des Crimpkontaktteils möglich ist. Das Zuführband ist bevorzugt metallisch, kann aber auch aus Kunststoff sein. Das am Zuführband gehaltene Crimpkontaktteil ist bereits vorgeformt. Im Falle eines Crimpkontaktteils mit Crimpbereich und Kontaktbereich ist der Kontaktbereich bevorzugt bereits vollständig ausgeformt bzw. ausgebildet, so dass zur späteren Verwendung als beispielsweise Stecker oder Buchse keine weitere Umformung notwendig ist. Der Crimpbereich ist bevorzugt ebenfalls vorgeformt, so dass zur Verbindung mit der Ader lediglich eine finale und geringe Umformung erforderlich ist, aber gleichzeitig ein Einlegen der Ader nicht unnötig behindert wird.The crimp contact parts are preferably fed to the crimping device by means of a feed belt. Each crimp contact part is preferably held at least on one side on the feed belt, the connection between the feed belt and the crimp contact part being such that a predetermined breaking point enables the crimp contact part to be easily separated or sheared from the feed belt without substantial damage or deformation of the crimp contact part. The feed belt is preferably metallic, but can also be made of plastic. The crimp contact part held on the feed belt is already preformed. In the case of a crimp contact part with a crimp area and a contact area, the contact area is preferably already completely formed, so that no further shaping is necessary for later use as a plug or socket, for example. The crimp area is preferably also preformed, so that only a final and slight deformation is required for connection to the wire, but at the same time insertion of the wire is not unnecessarily hindered.

Die bevorzugt vorgesehene Zuführbandführungsvorrichtung ist bevorzugt als Führungsschlitz in dem Abtrennmesser vorgesehen. Das Abtrennmesser bzw. der darin ausgebildete Führungsschlitz dient also zum Führen des Zuführbandes. Der Führungsschlitz ist dabei so ausgebildet, dass nur das Zuführband in diesem geführt ist und das an dem Zuführband gehaltene Crimpkontaktteil von diesem vorsteht. Der Crimpamboss und das Abtrennmesser sind aufeinander gleitend gelagert. Das Crimpkontaktteil steht derart vor, dass eine Abstützfläche des Crimpamboss mit dem vorstehenden Crimpkontaktteil in Berührung ist oder in einer gleitenden Relativbewegung zwischen Crimpkontaktteil und Crimpamboss in Berührung kommen kann. Solange das Crimpkontaktteil nicht sicher zwischen dem Crimper und dem Crimpamboss gehalten ist, wird das Crimpkontaktteil, während es am Zuführband, das in dem Führungsschlitz geführt ist, gehalten ist, mit dem Crimpamboss gemeinsam auf den Crimper zu bewegt. Mit dem Anschlag des Abtrennmessers am Crimper oder einem zu dem Crimper ortsfesten Anschlag wird das an der Abstützfläche des Crimpambosses abgestützte Crimpkontaktteil mit dem Crimpamboss zusammen weiter in Richtung auf den Crimper zu mitbewegt während das Abtrennmesser ortsfest bleibt. Durch die Relativbewegung wird das Crimpkontaktteil durch die dem Abtrennmesser zugewandte Kante der Abstützfläche oder eine am Crimpamboss nahe der Abstützfläche vorgesehene Abscherkante und die dem Crimpamboss zugewandte Kante des Abtrennmessers abgeschert.The feed belt guide device that is preferably provided is preferably provided as a guide slot in the severing knife. The severing knife or the guide slot formed therein thus serves to guide the feed belt. The guide slot is designed such that only the feed belt is guided in it and the crimp contact part held on the feed belt protrudes therefrom. The crimping anvil and the severing knife are slidably mounted on each other. The crimp contact part projects in such a way that a support surface of the crimp anvil is in contact with the projecting crimp contact part or comes into contact in a sliding relative movement between the crimp contact part and the crimp anvil can. As long as the crimp contact part is not securely held between the crimper and the crimp anvil, the crimp contact part is moved together with the crimp anvil towards the crimper while it is held on the feed belt which is guided in the guide slot. With the stop of the cutting knife on the crimper or a stop fixed to the crimper, the crimp contact part supported on the supporting surface of the crimp anvil is moved further together with the crimp anvil in the direction of the crimper, while the cutting knife remains stationary. As a result of the relative movement, the crimp contact part is sheared off by the edge of the support surface facing the severing knife or a shearing edge provided on the crimping boss near the supporting surface and the edge of the severing knife facing the crimping boss.

"Nach oben geöffnet" bedeutet hier, dass die umzuformenden bzw. umgeformten Bereiche des Crimpbereichs des Crimpkontaktteils über den nicht-umzuformenden bzw. nicht-umgeformten Bereichen angeordnet sind und/oder die mit dem Crimpkontaktteil zu crimpende Ader von oben nach unten eingesetzt wird. Nicht-umzuformende Bereiche sind Bereiche des Crimpbereichs, die beim Crimpen nicht oder zumindest nicht signifikant umgeformt werden. Bevorzugt überlappen die nicht-umzuformenden Bereiche senkrecht zur Längsrichtung des Crimpkontaktteils (=Längsrichtung der Ader) mit den umzuformenden Bereichen. "Nach unten geöffnet" bedeutet umgekehrt dass die umzuformenden bzw. umgeformten Bereiche des Crimpkontaktteils unter den nicht-umzuformenden bzw. nicht-umgeformten Bereichen angeordnet sind und/oder die mit dem Crimpkontaktteil zu crimpende Ader von unten nach oben eingesetzt wird."Opened upwards" here means that the regions of the crimp region of the crimp contact part to be formed or reshaped are arranged above the regions that are not to be reshaped or formed and / or the wire to be crimped with the crimp contact part is inserted from top to bottom. Areas not to be reshaped are areas of the crimping area which are not or at least not significantly reshaped during crimping. The areas not to be reshaped preferably overlap with the areas to be reshaped perpendicular to the longitudinal direction of the crimp contact part (= longitudinal direction of the wire). Conversely, "opened downwards" means that the regions of the crimp contact part to be formed or reshaped are arranged below the regions not to be reshaped or formed, and / or that the wire to be crimped with the crimp contact part is inserted from bottom to top.

Die beanspruchte und gegenüber herkömmlichen Crimpvorrichtungen nur geringfügig modifizierte Crimpvorrichtung ermöglicht das Inverscrimpen, d.h. Crimpkontaktteile um 180° gedreht zur Standard-Crimpvorrichtung zu crimpen. In einem Crimpsystem, bestehend aus einer Standard-Crimpvorrichtung und einer Invers-Crimpvorrichtung, wie sie hier beschrieben wird, kann somit eine erste Ader einer mehradrigen Leitung in der Standard-Crimpvorrichtung mit einem ersten Crimpkontaktteil und eine zweite Ader der mehradrigen Leitung in der Invers-Crimpvorrichtung mit einem Crimpkontaktteil, dass um 180° bezüglich des ersten Crimpkontaktteils gedreht ist, versehen werden, ohne dass die mehradrige Leitung zwischen den Crimpvorgängen um ihre Längsachse gedreht werden muss. Die mehradrige Leitung kann daher durchgehend eingespannt bzw. festgeklemmt sein, wodurch die Bearbeitungszeit verringert wird und eine hohe Position- und Lagerichtigkeit der mehradrigen Leitungen zur Crimpvorrichtung bzw. den Crimpkontaktteilen ermöglicht wird.The claimed crimping device, which is only slightly modified compared to conventional crimping devices, enables inverse crimping, ie crimping contact parts rotated by 180 ° to the standard crimping device. In a crimping system, consisting of a standard crimping device and an inverse crimping device, as described here, a first wire of a multi-core line in the standard crimping device can thus have a first crimp contact part and a second wire of the multi-wire line in the inverse The crimping device can be provided with a crimp contact part which is rotated through 180 ° with respect to the first crimp contact part, without the multi-core line having to be rotated about its longitudinal axis between the crimping processes. The multi-core cable can therefore be continuously clamped or clamped, reducing the processing time is reduced and a high position and position correctness of the multi-core cables to the crimping device or the crimp contact parts is made possible.

Der Crimpvorgang ist bevorzugt zumindest der Vorgang, bei dem die Ader durch Umformung des Crimpkontaktteils mit demselben fest verbunden wird bzw. das Crimpkontaktteil durch Umformen desselben mit der Ader fest verbunden wird. Der Crimpamboss ist dabei bevorzugt das Werkzeug, dass das Crimpkontaktteil während des Crimpvorgangs mindestens von oben her abstützt. Bevorzugt dient der Crimpamboss nicht unmittelbar zum Umformen der umzuformenden Bereiche des Crimpkontaktteils, insbesondere sind die zu crimpenden Crimpkontaktteile bevorzugt nicht in Richtung zu dem Crimpamboss hin geöffnet. Der Crimper ist umgekehrt dazu ausgebildet, die umzuformenden Bereiche (oder zumindest einen Großteil derselben) des am Crimpamboss abgestützten Crimpkontaktteils in dem Crimpvorgang in einer Relativbewegung zwischen dem Crimpamboss und dem Crimper umzuformen. Die zu crimpenden Crimpkontaktteile sind bevorzugt in Richtung zu dem Crimper hin geöffnet. In einigen Ausführungsformen ist nicht ausgeschlossen, dass Bereiche des Crimpkontaktteils auch durch den Crimpamboss umgeformt werden. Werden Crimpkontaktteile verwendet, die bereits im Ausgangszustand "geschlossen" sind, ist der Crimper auf der Seite angeordnet, auf der im Crimpvorgang die Überlappung der umzuformenden Bereiche zueinander vergrößert oder verändert wird.The crimping process is preferably at least the process in which the wire is firmly connected to the wire by reshaping the crimp contact part or the crimp contact part is firmly connected to the wire by reshaping the same. The crimping anvil is preferably the tool that supports the crimp contact part at least from above during the crimping process. The crimp anvil is preferably not used directly for reshaping the regions of the crimp contact part to be reshaped, in particular the crimp contact parts to be crimped are preferably not opened in the direction of the crimp anvil. Conversely, the crimper is designed to shape the regions (or at least a large part thereof) of the crimp contact part supported on the crimp anvil in the crimping process in a relative movement between the crimp anvil and the crimper. The crimp contact parts to be crimped are preferably opened in the direction of the crimper. In some embodiments, it is not excluded that regions of the crimp contact part are also deformed by the crimping boss. If crimp contact parts are used which are already "closed" in the initial state, the crimper is arranged on the side on which the overlap of the regions to be reshaped to one another is enlarged or changed in the crimping process.

Im Folgenden wird eine erste Ausführungsform einer Invers-Crimpvorrichtung 10 mit Bezugnahme auf Fig. 1, die eine Querschnittsansicht derselben zeigt, beschrieben.A first embodiment of an inverse crimping device 10 is described below with reference to FIG Fig. 1 which shows a cross-sectional view of the same.

Die Invers-Crimpvorrichtung 10 weist einen starr beispielsweise an einer Bodenplatte 28 montierten Crimper 18 auf. In dieser Ausführungsform ist der Crimper 18 beispielhaft mittels einer Schraube 30 an einem Sockel 32 befestigt, welcher auf der Bodenplatte 28 montiert ist.The inverse crimping device 10 has a crimper 18 rigidly mounted, for example, on a base plate 28. In this embodiment, the crimper 18 is fastened, for example, by means of a screw 30 to a base 32 which is mounted on the base plate 28.

Der Crimper 18 dient dazu, wie später beschrieben wird, in einem Crimpvorgang umzuformende Bereiche 20 eines an einem Crimpamboss 16 abgestützten Crimpkontaktteils 12 umzuformen (siehe auch Fig. 5A). Hierzu weist der Crimper 18 im oberen Bereich einen nicht näher dargestellten Crimperbereich 34 auf. Der Crimperbereich 34 kann beispielsweise aus V-oder U-förmigen Nasen ausgebildet sein, die an die spezifische Form der umzuformenden Bereiche 20 des oder der Crimpkontaktteile 12 angepasst ist. Der Crimperbereich 34 kann zum Umformen von einem einzelnen oder mehreren Crimpkontaktteilen 12 gleichzeitig ausgebildet sein. Der Sockel 32 weist ebenfalls im oberen Bereich, hier horizontal versetzt zu dem Crimperbereich, einen Anschlag 26 auf, dessen Funktion später beschrieben wird.The crimper 18 serves, as will be described later, to reshape regions 20 of a crimp contact part 12 supported on a crimp anvil 16 in a crimping process (see also Figure 5A ). For this purpose, the crimper 18 has a crimper area 34, not shown in the upper area. The crimper region 34 can be formed, for example, from V-shaped or U-shaped lugs, which is adapted to the specific shape of the regions 20 of the crimp contact part or parts 12 to be shaped. The crimper region 34 can be designed for reshaping a single or a plurality of crimp contact parts 12 at the same time. The base 32 likewise has a stop 26 in the upper region, here horizontally offset from the crimper region, the function of which will be described later.

Vertikal über dem Crimper 18 ist ein Crimpamboss 16 vorgesehen. Der Crimpamboss 16 ist mittels einer Antriebseinheit 36 in der vertikalen Richtung bewegbar gehalten. An seiner Unterseite weist der Crimpamboss 16 einen nicht näher dargestellten Abstützbereich (Abstützfläche) 38 auf. Der Abstützbereich 38 liegt dem Crimperbereich 34 in der vertikalen Richtung gegenüber und ist zum Abstützen eines Crimpkontaktteils 12 (von oben her) ausgebildet.A crimp anvil 16 is provided vertically above the crimper 18. The crimping anvil 16 is held movably in the vertical direction by means of a drive unit 36. On its underside, the crimping anvil 16 has a support area (support surface) 38, which is not shown in detail. The support area 38 lies opposite the crimper area 34 in the vertical direction and is designed to support a crimp contact part 12 (from above).

Die Antriebseinheit 36 ist so ausgebildet, dass der Crimpamboss 16 zum Ausführen des Crimpvorgangs von einer ersten vertikalen Stellung (Ruheposition), in der er mit einem vorbestimmten vertikalen Abstand zu dem Crimper 18 beabstandet ist, in eine zweite vertikale Stellung, in der die umzuformenden Bereiche 20 des Crimpkontaktteils 12 vollständig umgeformt sind, auf den Crimper 18 zu bewegbar ist. Der Crimpamboss 16 und der Crimper 18 können in der zweiten Stellung zumindest im Bereich des Abstützbereichs 38 und des Crimperbereichs 34 in der Horizontalrichtung überlappen, d.h. ineinandergreifen. Die Antriebseinheit 36 ist beispielsweise ein Elektromotor mit Getriebe (z.B.: Schneckengetriebe, Zahnstangenantrieb) oder ein hydraulischer oder pneumatischer Antrieb. Die Antriebseinheit enthält eine entsprechende Steuerung.The drive unit 36 is designed such that the crimping anvil 16 for carrying out the crimping process from a first vertical position (rest position), in which it is spaced a predetermined vertical distance from the crimper 18, into a second vertical position, in which the regions to be formed 20 of the crimp contact part 12 are completely deformed, towards which the crimper 18 can be moved. In the second position, the crimping anvil 16 and the crimper 18 can overlap in the horizontal direction, at least in the region of the support region 38 and the crimper region 34, that is to say they interlock. The drive unit 36 is for example an electric motor with gear (e.g. worm gear, rack and pinion drive) or a hydraulic or pneumatic drive. The drive unit contains a corresponding control.

Der Amboss 16 weist weiter eine bevorzugt starr, auch über dritte Bauteile, am Amboss befestigte Führungsplatte (Führungsmittel) 40 auf. Der Amboss 16 und die Führungsplatte 40 sind so ausgebildet bzw. aneinander befestigt, dass zwischen ihnen ein Abtrennmesser 22 (nur) vertikal beweglich geführt wird. Zur vertikalen Führung des Abtrennmesser 22 weist die Führungsplatte 40 ein vertikales Langloch 42 auf, in dem ein starr an dem Abtrennmesser 22 angebrachter Führungsbolzen 44, der von dem Abtrennmesser 22 vorsteht, in vertikaler Richtung zwischen einer oberen Anschlagposition und einer unteren Anschlagposition geführt wird. Das Abtrennmesser 22 ist also zwischen einer oberen und einer unteren Anschlagposition bewegbar, wobei lediglich die untere Anschlagposition angefahren wird und die obere Anschlagposition weggelassen werden könnte. Bevorzugt wird das Abtrennmesser 22 beispielsweise über eine Feder 45 in die untere Anschlagposition vorgespannt.The anvil 16 also has a guide plate (guide means) 40, preferably rigid, also via third components, attached to the anvil. The anvil 16 and the guide plate 40 are designed or fastened to one another in such a way that a separating knife 22 (only) is guided between them in a vertically movable manner. For the vertical guidance of the severing knife 22, the guide plate 40 has a vertical elongated hole 42 in which a guide bolt 44, which is rigidly attached to the severing knife 22 and projects from the severing knife 22, is guided in a vertical direction between an upper stop position and a lower stop position. The separating knife 22 can thus be moved between an upper and a lower stop position, only the lower stop position being approached and the upper stop position could be omitted. The severing knife 22 is preferably biased into the lower stop position, for example, by a spring 45.

In der unteren Anschlagposition ist das Abtrennmesser 22 in seiner vertikal untersten Position bezüglich bzw. relativ zu dem Crimpamboss 16. Das untere Ende des Abtrennmessers 22 steht in dieser unteren Anschlagposition von dem Amboss 16 nach unten in Richtung zu dem Crimper 18 bzw. der Bodenplatte 28 vor. Der Abstützbereich 38 bzw. der Amboss 16 und das Abtrennmesser 22 sind so ausgebildet, dass der nach unten vorstehende Bereich des Abtrennmessers 22 in horizontaler Richtung benachbart (in horizontaler Richtung überlappend) zu dem Abstützbereich 38 ausgebildet ist. In dieser Ausführungsform steht der nach unten vorstehende Bereich in der ersten Stellung des Crimpambosses 16 so weit vor, dass er auch bereichsweise in horizontaler Richtung benachbart (in horizontaler Richtung überlappend) zu dem Crimperbereich 34, zumindest dessen oberen Ende, angeordnet ist.In the lower stop position, the severing knife 22 is in its vertically lowest position with respect to or relative to the crimping anvil 16. In this lower stop position, the lower end of the severing knife 22 stands downward from the anvil 16 towards the crimper 18 or the base plate 28 in front. The support area 38 or the anvil 16 and the cut-off knife 22 are designed such that the downwardly projecting area of the cut-off knife 22 is formed adjacent to the support area 38 in the horizontal direction (overlapping in the horizontal direction). In this embodiment, the downwardly protruding area projects so far in the first position of the crimping boss 16 that it is also partially adjacent in the horizontal direction (overlapping in the horizontal direction) to the crimper area 34, at least its upper end.

In dem nach unten vorstehenden Bereich des Abtrennmessers 22 ist auf der dem Amboss 16 zugewandten Seite (obere Seite, oberer Endbereich des nach unten vorstehenden Bereichs) ein bevorzugt horizontaler Führungsschlitz 46 zur Aufnahme eines Zuführbands (auch als Kontaktstreifen bezeichnet) 24, mit dem die Crimpkontaktteile 12 zugeführt werden, vorgesehen. Der Führungsschlitz ist auf der Seite zu dem Crimpamboss hin geöffnet. Das Zuführband 24 ist beispielsweise ein metallisches Band, an dem die Crimpkontaktteile 12 beispielsweise einseitig (an einem Ende in ihrer Längsrichtung) gehalten werden. Der Führungsschlitz 46 ist so vorgesehen, dass, wenn das Abtrennmesser 22 in seiner unteren Anschlagposition ist (und der Crimpamboss in seiner Ausgangslage (erste Stellung) ist), die Crimpkontaktteile 12 in einer Richtung senkrecht zur Zeichenebene von Fig. 1 (horizontal) zugeführt werden können, ohne mit dem Abstützbereich 38 des Ambosses 16 oder dem Crimperbereich 34 des Crimpers 18 zu kollidieren. Mindestens ein am Zuführband gehaltenes Crimpkontaktteil selbst (also nicht das Zuführband) steht dabei auf der geöffneten Seite des Führungsschlitzes aus dem Führungsschlitz in den Bereich zwischen Crimpamboss und Crimper (Überlappungsbereich) vor. Es befindet sich also nur das Zuführband in dem Führungsschlitz und nur das Crimpkontaktteil zwischen dem Crimpamboss und dem Crimper.In the downwardly projecting area of the severing knife 22, on the side facing the anvil 16 (upper side, upper end area of the downwardly projecting area) there is a preferably horizontal guide slot 46 for receiving a feed band (also referred to as a contact strip) 24 with which the crimp contact parts 12 are provided. The guide slot is open on the crimp anvil side. The feed belt 24 is, for example, a metallic belt on which the crimp contact parts 12 are held, for example, on one side (at one end in their longitudinal direction). The guide slot 46 is like this provided that when the severing knife 22 is in its lower stop position (and the crimping boss is in its initial position (first position)), the crimping contact parts 12 in a direction perpendicular to the plane of the drawing of Fig. 1 can be supplied (horizontally) without colliding with the support area 38 of the anvil 16 or the crimper area 34 of the crimper 18. At least one crimp contact part itself (ie not the feed belt) held on the feed belt projects from the guide slot on the open side of the guide slot into the area between the crimping boss and the crimper (overlap area). So there is only the feed belt in the guide slot and only the crimp contact part between the crimping boss and the crimper.

Zwischen dem unteren Ende (dem dem Crimper 18 zugewandten Ende) des Abtrennmesser 22 und dem Führungsschlitz 46 ist in dem vorstehenden Bereich des Abtrennmessers 22 weiter eine Adereinführöffnung 48 vorgesehen. Die Adereinführöffnung 48 ist bevorzugt konisch, d.h. sich von der dem Amboss 16 abgewandten Seite verjüngend, ausgebildet und dient somit zum einfachen Einführen einer mit dem Crimpkontaktteil 12 zu crimpenden Ader 14. Das untere (äußerste) Ende des Abtrennmessers 22 dient, wie später beschrieben werden wird, als ein Anschlagbereich 50 des Abtrennmessers 22.Between the lower end (the end facing the crimper 18) of the separating knife 22 and the guide slot 46, a wire insertion opening 48 is further provided in the projecting area of the separating knife 22. The wire insertion opening 48 is preferably conical, i.e. tapers from the side facing away from the anvil 16 and thus serves for the simple insertion of a wire 14 to be crimped with the crimp contact part 12. The lower (outermost) end of the cutting knife 22 serves, as will be described later, as a stop area 50 of the cutting knife 22.

Die so ausgewählte Invers-Crimpvorrichtung 10 wird, wie es anhand der Figuren 2A bis 2E beschrieben werden wird, wie folgt betrieben. Figuren 2A bis 2E basieren auf Fig. 1, zeigen aber nicht alle vorher beschriebenen Bauteile. Des Weiteren sind nicht alle Bezugszeichen in allen Figuren eingezeichnet.The inverse crimping device 10 selected in this way is, as is shown in FIG Figures 2A to 2E will be described as follows. Figures 2A to 2E based on Fig. 1 , but do not show all the components previously described. Furthermore, not all reference numerals are shown in all figures.

In dem in Fig. 1 und 2A gezeigten Ausgangszustand (Ruheposition) der Invers-Crimpvorrichtung 10 ist der Crimpamboss 16 in seiner ersten vertikalen Stellung (oberste Stellung) und das Abtrennmesser 22 in seiner bezüglich des Ambosses 16 untersten Stellung (ebenfalls Ruheposition oder Ausgangsstellung, erste Position). Weiter ist bereits ein Crimpkontaktteil 12 mittels des Zuführbands 24 an eine Position zwischen den Crimpamboss 16, insbesondere den Abstützbereich 38, und den Crimper 18, insbesondere den Crimperbereich 34, zugeführt. Das Crimpkontaktteil 12 ist bevorzugt sehr nahe oder in Anlage (in Berührung) mit dem Abstützbereich 38.In the in Fig. 1 and 2A The initial state (rest position) of the inverse crimping device 10 shown is the crimping boss 16 in its first vertical position (uppermost position) and the severing knife 22 in its lowest position with respect to the anvil 16 (likewise rest position or starting position, first position). Furthermore, a crimp contact part 12 has already been fed by means of the feed belt 24 to a position between the crimping boss 16, in particular the support region 38, and the crimper 18, in particular the crimper region 34. The crimp contact part 12 is preferably very close or in contact (in contact) with the support region 38.

Weiter ist die Ader 14 beispielsweise einer mehradrigen Leitung von links nach rechts in die Invers-Crimpvorrichtung 10, insbesondere die Adereinführöffnung 48 so weit eingeführt, dass die Ader 14 vertikal unter dem Crimpkontaktteil 12 angeordnet ist und mit demselben überlappt (siehe auch Fig. 1). Die Invers-Crimpvorrichtung 10 ist also so ausgebildet, dass das Crimpkontaktteil 12 und die Ader 14 vertikal übereinander in dem vertikalen Zwischenraum zwischen dem Abstützbereich 38 das Crimpambosses 16 und dem Crimperbereich 34 des Crimpers 18 Platz finden.Furthermore, the wire 14, for example of a multi-wire line, is inserted from left to right into the inverse crimping device 10, in particular the wire insertion opening 48, so that the wire 14 is arranged vertically under the crimp contact part 12 and overlaps it (see also Fig. 1 ). The inverse crimping device 10 is thus designed in such a way that the crimp contact part 12 and the wire 14 are placed vertically one above the other in the vertical space between the support area 38, the crimping boss 16 and the crimper area 34 of the crimper 18.

Wie es aus einem Vergleich der Fig. 2A mit der Fig. 2B, die eine nachfolgende Bewegungsposition zeigt, zu sehen ist, wird nun in einem ersten Schritt der Crimpamboss 16 mittels der Antriebseinheit 36 (hier nicht gezeigt) nach unten, in Richtung zu dem Crimper 18 (in Richtung zu der zweiten vertikalen Stellung des Crimpambosses 16) hin, bewegt. Da das Abtrennmesser 22 über die Feder 45 (hier nicht gezeigt) stark genug nach unten vorgespannt ist, bewegt sich das Abtrennmesser 22 zusammen mit dem Crimpamboss 16 nach unten. Das im Führungsschlitz 46 geführte Zuführband 24 wird mit dem daran angebrachten Crimpkontaktteil 12 somit ebenfalls nach unten bewegt. In der nach unten Bewegung des Abtrennmessers 22 kommt die in die Adereinführöffnung 48 eingeführte und in einer hier nicht gezeigten und später beschriebenen Ader-Zuführeinrichtung vorerst ortsfest gehaltene Ader 14 mit der oberen Kante der Adereinführöffnung 48 in Berührung und wird ebenfalls mit nach unten mitbewegt. Damit die Ader 14 nicht gebogen wird, kann die später beschriebene Ader-Zuführeinrichtung so ausgebildet, dass sie eine Mitbewegung der Ader 14 nach unten erlaubt, d.h., sie senkt sich bevorzugt zusammen mit der Ader 14 ab. Gegebenenfalls kann hierzu auch eine mechanische und/oder elektrische oder sonst wie geartete Kopplung mit der Bewegung des Abtrennmessers vorgesehen sein. Des Weiteren kommt der Crimperbereich 34 des Crimpers 18 mit dem Crimpkontaktteil 12 in Berührung.As it is from a comparison of the Figure 2A with the Figure 2B , which shows a subsequent movement position, can now be seen in a first step, the crimping anvil 16 by means of the drive unit 36 (not shown here) downwards, in the direction of the crimper 18 (in the direction of the second vertical position of the crimping anvil 16) there, moved. Since the severing knife 22 is biased downwards sufficiently strongly by the spring 45 (not shown here), the severing knife 22 moves downward together with the crimping boss 16. The feed belt 24 guided in the guide slot 46 is thus also moved downward with the crimp contact part 12 attached to it. In the downward movement of the separating knife 22, the wire 14 inserted into the wire insertion opening 48 and initially held stationary in a wire feeding device (not shown here and described later) comes into contact with the upper edge of the wire insertion opening 48 and is also moved downward. So that the wire 14 is not bent, the wire feed device described later can be designed in such a way that it allows the wire 14 to move downward, ie it preferably lowers together with the wire 14. If necessary, a mechanical and / or electrical or other type of coupling with the movement of the cutting knife can also be provided for this purpose. Furthermore, the crimper region 34 of the crimper 18 comes into contact with the crimp contact part 12.

Ausgehend von der in Fig. 2B gezeigten Position kommt der Crimperbereich 34 in der weiteren nach unten Bewegung (in den Zustand von Fig. 2C) des Crimpambosses 16 in Richtung auf den Crimper 18 zu zunehmend mit den umzuformenden Bereichen 20 des Crimpkontaktteils 12 in Berührung, wodurch das Crimpkontaktteil 12 zunehmend fester zwischen dem Abstützbereich 38 und dem Crimperbereich 34 gehalten wird. In dieser fortschreitenden Bewegung des Crimpambosses 16 findet beispielsweise ein erstes plastisches Umformen der umzuformenden Bereiche 20 statt, was zu einer ersten Berührung und wenigstens teilweisen Umschließung der Ader 14 durch das Crimpkontaktteil 12 führen kann. Der Crimperbereich 34 kommt in dieser Bewegung in dieser Ausführungsform zunehmend in Überlappungen (horizontal) mit dem Abstützbereich 38. Die Ader 14 wird weiterhin mit der Bewegung des Abtrennmessers 22 durch Anlage an der oberen Kante der Adereinführöffnung 48 mit nach unten bewegt.Starting from the in Figure 2B In the position shown, the crimper region 34 comes in the further downward movement (in the state of Figure 2C ) of the crimping boss 16 in the direction of the crimper 18 increasingly in contact with the regions 20 of the crimp contact part 12 to be reshaped, as a result of which the crimp contact part 12 is held increasingly firmly between the support region 38 and the crimper region 34. In this progressive movement of the crimping boss 16, for example, a first plastic forming of the areas 20 to be formed takes place, which can lead to a first contact and at least partial encasing of the wire 14 by the crimp contact part 12. In this embodiment, the crimper region 34 increasingly overlaps (horizontally) with the support region 38 in this embodiment. The wire 14 continues to move with the movement of the severing knife 22 moved by abutting the upper edge of the wire insertion opening 48 with.

In Fig. 2C ist eine Position erreicht, in der das Crimpkontaktteil 12 sicher zwischen dem Crimperbereich 34 und dem Abstützbereich 38 gehalten wird. Es besteht daher kein Bedarf mehr dafür, dass das Crimpkontaktteil 12 an dem Zuführband 24 gehalten wird. Aus diesem Grund sind das Abtrennmesser 22, insbesondere dessen Anschlagbereich 50, und der Sockel 32 bzw. der Anschlag 26 so ausgebildet und zueinander angeordnet, dass in der in Fig. 2C gezeigten Position der Anschlagbereich 50 des Abtrennmessers 22 mit dem Anschlag 26, der an dem Sockel 32 des Crimpers 18 vorgesehen ist, in Berührung kommt.In Figure 2C a position is reached in which the crimp contact part 12 is securely held between the crimper area 34 and the support area 38. There is therefore no longer any need for the crimp contact part 12 to be held on the feed belt 24. For this reason, the separating knife 22, in particular its stop area 50, and the base 32 or the stop 26 are designed and arranged with respect to one another in such a way that in FIG Figure 2C shown position of the stop area 50 of the severing knife 22 comes into contact with the stop 26, which is provided on the base 32 of the crimper 18.

In der weiteren Bewegung des Crimpambosses 16 auf den Crimper 18 zu (in die in Fig. 2D gezeigte zweite vertikale Stellung) kann somit das Abtrennmesser 22 nicht mehr zusammen mit dem Crimpamboss 16 mitbewegt werden. Stattdessen resultiert die weitere Bewegung des Crimpambosses 16 auf den Crimper 18 zu in einer Relativbewegung zwischen dem Crimpamboss 16 und dem nunmehr ortsfesten (nicht mehr mitbewegten) Abtrennmesser 22 in eine zweite Position, was zu einer Abscherung des Crimpkontaktteils 12 vom Zuführband 24 führt. Mit anderen Worten, dass Crimpkontaktteil 12 wird zusammen mit der darin eingelegten Ader 14 weiter mit dem Crimpamboss 16 nach unten bewegt, wohingegen das im Abtrennmesser 22 geführte Zuführband 24 nicht nach unten bewegt wird, was zu der Abscherung führt. Die Abscherung erfolgt dabei bevorzugt zwischen der unteren rechten (der dem Crimper näheren und dem Crimpamboss zugewandten) Kante des Führungsschlitzes und der dem Abtrennmesser zugewandten Kante des Abstützbereichs des Crimpambosses. Alternativ kann auch am Abtrennmesser und/oder am Crimpamboss eine spezielle Abscherkante vorgesehen sein.In the further movement of the crimping anvil 16 towards the crimper 18 (into the in Figure 2D shown second vertical position), the separating knife 22 can therefore no longer be moved together with the crimping boss 16. Instead, the further movement of the crimping anvil 16 on the crimper 18 results in a relative movement between the crimping anvil 16 and the now stationary (no longer moved) separating knife 22 into a second position, which leads to shearing of the crimp contact part 12 from the feed belt 24. In other words, the crimp contact part 12, together with the wire 14 inserted therein, is moved further downward with the crimping boss 16, whereas the feed belt 24 guided in the separating knife 22 is not moved downward, which leads to the shearing off. The shearing is preferably carried out between the lower right edge (the edge closer to the crimper and facing the crimp anvil) of the guide slot and the edge of the support area of the crimp anvil facing the severing knife. Alternatively, a special shearing edge can also be provided on the severing knife and / or on the crimping anvil.

In dieser Bewegung des Crimpambosses 16 in die Fig. 2D gezeigte zweite vertikale Stellung, d.h. in der Relativbewegung zwischen dem Crimpamboss 16 und dem Crimper 18 erfolgt (gleichzeitig) bevorzugt auch die Vollendung des Crimpvorgangs. Die Ader 14 kommt außer Eingriff mit der oberen Kante der Adereinführöffnung 48 und die umzuformenden Bereiche 20 werden in ihre finale gecrimpte Position (plastisch) umgeformt. Dabei wird die Ader 14 in der nach unten Bewegung des Crimpambosses 16 zusammen mit dem Crimpkontaktteil 12 nach unten bewegt. Die Ader 14 und das Crimpkontaktteil 12 sind nun fest miteinander verbunden (vercrimpt).In this movement of the crimping boss 16 in the Figure 2D Second vertical position shown, ie in the relative movement between the crimping anvil 16 and the crimper 18, the crimping process is preferably (simultaneously) also completed. The wire 14 disengages from the upper edge of the wire insertion opening 48 and the areas 20 to be reshaped are (plastically) reshaped into their final crimped position. The wire 14 is moved in the downward movement of the crimping boss 16 together with the crimp contact part 12. The wire 14 and the crimp contact part 12 are now firmly connected to one another (crimped).

Im nächsten Schritt wird der Crimpamboss 16 zurück nach oben bewegt, wodurch zuerst das gecrimpte Crimpkontaktteil 12 freigegeben wird und zusammen mit der Ader 14 beispielsweise nach links entfernt werden kann. Nach der Rückkehr des Crimpambosses 16 und die entsprechenden Rückkehr des Abtrennmessers 22 in ihre Ausgangslagen kann, wie es in Fig. 2E gezeigt ist, bereits ein neues Crimpkontaktteil 12 über das Zuführband 24 zugeführt werden.In the next step, the crimp anvil 16 is moved back upward, as a result of which the crimped crimp contact part 12 is released first and can be removed together with the wire 14, for example to the left. After the return of the crimping boss 16 and the corresponding return of the severing knife 22 to their starting positions, as can be seen in Figure 2E is shown, a new crimp contact part 12 can already be fed via the feed belt 24.

Unter Crimpvorgang soll insbesondere die Bewegung verstanden werden, mit der das eigentliche Crimpen (Umformen) des Crimpkontaktteils auf die Ader bewirkt wird. Im Wesentlichen ist damit also hier die Bewegung des Crimpambosses von der ersten Stellung in die zweite Stellung gemeint.The crimping process is to be understood in particular as the movement with which the actual crimping (forming) of the crimp contact part onto the wire is effected. Essentially, this means the movement of the crimp anvil from the first position to the second position.

Fig. 3 zeigt eine weitere Ausführungsform der Crimpvorrichtung bei der zusätzlich zu den bisher beschriebenen Merkmalen eine Zuführband-Transportvorrichtung 52 und eine Ader-Zuführvorrichtung (auch als Ader- oder Kabelklemmvorrichtung bezeichnet) 54 vorgesehen sind. Fig. 3 shows a further embodiment of the crimping device in which, in addition to the features described so far, a feed belt transport device 52 and a wire feed device (also referred to as wire or cable clamping device) 54 are provided.

Die Zuführband-Transportvorrichtung 52 dient zum Zuführen des Zuführbandes 24 in das Abtrennmesser 22. Beispielsweise weist die Zuführband-Transportvorrichtung 52 zwei Rollen, von denen mindestens eine beispielsweise mittels eines über eine Steuerung gesteuerten Elektromotors drehangetrieben ist, auf, zwischen denen das Zuführband 24 transportiert wird. Bevorzugt ist das Zuführband 24 als Lochband ausgebildet, so dass ein entsprechender Zahnkranz den Transport bzw. Vortrieb übernehmen und die exakte Positionierung sicherstellen kann. Die Zuführband Transportvorrichtung 52 ist in dieser Ausführungsform starr mit dem Abtrennmesser 22 verbunden, so dass bei der vertikalen Bewegung des Abtrennmessers 22 zusammen mit dem Crimpamboss 16 eine Mitbewegung der Zuführband-Transportvorrichtung 52 erfolgt. Bevorzugt wird ein Schrittmotor eingesetzt, mit dem die diskontinuierliche Zuführung gewährleistet wird.The feed belt transport device 52 serves to feed the feed belt 24 into the severing knife 22. For example, the feed belt transport device 52 has two rollers, at least one of which is rotated, for example by means of an electric motor controlled by a control, between which the feed belt 24 is transported . The feed belt 24 is preferably designed as a perforated belt so that a corresponding toothed ring can take over the transport or advance and ensure the exact positioning. In this embodiment, the feed belt transport device 52 is rigidly connected to the severing knife 22, so that during the vertical movement of the severing knife 22 together with the crimping boss 16, the feed belt transport device 52 also moves. A stepper motor is preferably used, with which the discontinuous supply is ensured.

Die Ader-Zuführvorrichtung 54 dient zum Zuführen und Positionieren der Ader 14 in der Invers-Crimpvorrichtung 10. Insbesondere ermöglicht sie ein zumindest in Längsrichtung der Ader genaues Positionieren des zu crimpenden Teils der Ader an einer vorbestimmten Relativposition zum Crimpkontaktteil. Beispielsweise weist die Ader-Zuführvorrichtung 54 zwei Rollen oder Walzen, von denen mindestens eine beispielsweise mittels eines über eine Steuerung gesteuerten Elektromotors drehangetrieben ist, auf, mittels derer die Ader 14 transportiert und geklemmt wird. Bevorzugt wird mit der Ader-Zuführvorrichtung 54 die zu der jeweiligen Ader gehörende mehradrige Leitung transportiert und positioniert und werden nur eine vorbestimmte Anzahl der Adern in die Crimpvorrichtung eingeführt und ggfs. nach dem Crimpen wieder heraus transportiert.The wire feed device 54 serves to feed and position the wire 14 in the inverse crimping device 10. In particular, it enables the part of the wire to be crimped to be precisely positioned at least in the longitudinal direction of the wire at a predetermined relative position to the crimp contact part. For example, the wire feed device 54 has two rollers, at least one of which, for example, by means of a controller Controlled electric motor is driven in rotation, by means of which the wire 14 is transported and clamped. The multi-core line belonging to the respective core is preferably transported and positioned with the core feed device 54 and only a predetermined number of the cores are inserted into the crimping device and, if necessary, transported out again after crimping.

Die Ader-Zuführvorrichtung 54 ist in dieser Ausführungsform beispielsweise über Federn vertikal bewegbar, so dass bei der beschriebenen nach unten Bewegung des Crimpambosses 16 zwischen der Position in Fig. 2B und Fig. 2D der in dem Crimpkontaktteil 12 befindlichen Ader 14 auch eine nach unten Bewegung der Ader-Zuführvorrichtung 54 stattfindet. Hierdurch wird eine mögliche Positionsänderung der Ader aufgrund einer Relativpositionsänderung zwischen Ader-Zuführvorrichtung 54 und Crimpamboss 16 vermieden. Die Ader-Zuführvorrichtung 54 kann auch starr am Crimpamboss 16 befestigt oder mit dem Crimpamboss mechanisch gekoppelt sein. Alternativ kommt auch eine über Sensoren gesteuerte Bewegung in Frage.In this embodiment, the wire feed device 54 can be moved vertically, for example by means of springs, so that in the described downward movement of the crimping boss 16 between the position in FIG Figures 2B and 2D of the wire 14 located in the crimp contact part 12 there is also a downward movement of the wire feed device 54. This avoids a possible change in the position of the wire due to a change in the relative position between the wire feed device 54 and the crimping boss 16. The wire feed device 54 can also be rigidly attached to the crimping boss 16 or mechanically coupled to the crimping boss. Alternatively, a movement controlled by sensors can also be used.

Die bezüglich der Umgebung bewegliche Lagerung sowohl der Zuführband-Transportvorrichtung 52 als auch der Ader-Zuführvorrichtung 54 dient somit zur Verringerung von Kräften, die aus der Bewegung des Crimpambosses 16 bzw. des Abtrennmessers 22 während des Crimpvorgangs resultieren. Die Zuführband-Transportvorrichtung 52, die Ader-Zuführvorrichtung 54 und die Antriebseinheit 36 können zentral oder dezentral gesteuert und ggfs. miteinander vernetzt sein.The storage of both the feed belt transport device 52 and the wire feed device 54, which is movable in relation to the environment, thus serves to reduce forces which result from the movement of the crimping boss 16 or the severing knife 22 during the crimping process. The feed belt transport device 52, the wire feed device 54 and the drive unit 36 can be controlled centrally or decentrally and, if necessary, networked with one another.

Fig. 4 zeigt eine Aufsicht auf ein Crimpsystem 56, in dem neben der in Fig. 3 gezeigten Invers-Crimpvorrichtung 10 eine weitere herkömmliche Crimpvorrichtung 56 vorgesehen ist. Die herkömmliche Crimpvorrichtung 58 unterscheidet sich von der oben beschriebenen Invers-Crimpvorrichtung 10 insbesondere dadurch, dass der Crimpamboss an der Stelle/Position des Crimpers und der Crimper an der Stelle/Position des Crimpamboss vorgesehen ist. Die einzelnen diesen Bauteilen zugewiesenen Funktionen bleiben dabei gleich. Es wird also ein Crimpkontaktteil, welches im Unterschied zur obigen Invers-Crimpvorrichtung 10 nach oben hin geöffnet ist, über ein Zuführband in den Crimpamboss zugeführt. Anschließend wird eine Ader beispielsweise von oben nach unten in das Crimpkontaktteil eingelegt (mittels einer Ader-Zuführvorrichtung 54) und erfolgt das Crimpen des Crimpkontaktteils auf die Ader durch Bewegen des Crimpers von oben nach unten auf den Crimpamboss zu (hier ist der Crimper über eine Antriebseinheit (nicht separat dargestellt) angetrieben). Fig. 4 shows a plan view of a crimping system 56, in which in addition to the in Fig. 3 Inverse crimping device 10 shown, another conventional crimping device 56 is provided. The conventional crimping device 58 differs from the inverse crimping device 10 described above in particular in that the crimping anvil is provided at the position / position of the crimper and the crimper at the position / position of the crimping anvil. The individual functions assigned to these components remain the same. A crimp contact part, which, in contrast to the above inverse crimping device 10, is open at the top, is fed into the crimping boss via a feed belt. A wire is then inserted into the crimp contact part, for example from top to bottom (by means of a wire feed device 54), and the crimp contact part is crimped onto the wire by moving the crimper from top to bottom towards the crimp anvil (here the crimper is driven by a drive unit (not shown separately)).

Weiter ist in dem gezeigten Crimpsystem 56 bevorzugt nur eine einzige Ader-Zuführvorrichtung (hier auch Kabelzuführvorrichtung) 54 vorgesehen, die bevorzugt horizontal (in der Zeichenebene) in zwei Richtungen (beispielsweise über einen Antrieb (Elektromotor)) gesteuert verfahrbar ausgebildet ist, so dass jeweils mindestens eine Ader 14 einer mehradrigen Leitung 58 zu sowohl der herkömmlichen Crimpvorrichtung 58 als auch der Invers-Crimpvorrichtung 10 zugeführt werden kann. Alternativ können die Crimpvorrichtungen 10, 56 verfahrbar ausgebildet sein.Furthermore, in the crimping system 56 shown, preferably only a single wire feed device (here also cable feed device) 54 is provided, which is preferably designed to be movable horizontally (in the drawing plane) in two directions (for example via a drive (electric motor)), so that in each case at least one wire 14 of a multi-core line 58 can be fed to both the conventional crimping device 58 and the inverse crimping device 10. Alternatively, the crimping devices 10, 56 can be designed to be movable.

Insbesondere kann ein nach oben geöffnetes Crimpkontaktteil 12 auf eine erste Ader 14 einer mehradrigen Leitung mittels der herkömmlichen Crimpvorrichtung 58 und ein nach unten geöffnetes Crimpkontaktteil 12 auf eine zweite Ader derselben mehradrigen Leitung 58 mittels der oben beschriebenen Invers-Crimpvorrichtung 10 gecrimpt werden. Die Leitung bzw. Adern müssen zwischen den Crimpvorgängen nicht um ihre Längsachse gedreht werden.In particular, a crimp contact part 12 which is open at the top can be crimped onto a first wire 14 of a multi-wire line by means of the conventional crimping device 58 and a crimp contact part 12 which is open at the bottom can be crimped onto a second wire of the same multi-wire line 58 by means of the inverse crimping device 10 described above. The cable or wires do not have to be rotated about their longitudinal axis between the crimping processes.

Bevorzugt ist jede der in Fig. 4 gezeigten Crimpvorrichtungen 10, 56 zum gleichzeitigen Crimpen zweier Crimpkontaktteile (jeweils beide nach oben oder nach unten geöffnet) ausgebildet. Beispielhaft werden also mittels der Ader-Zuführvorrichtung 54 zwei Adern 14 einer vieradrigen Leitung 58 in den Crimpamboss der herkömmlichen Crimpvorrichtung 56 zugeführt und gleichzeitig mit nach oben geöffneten Crimpkontaktteilen versehen. Anschließend werden die gecrimpten Adern aus der herkömmlichen Crimpvorrichtung 58 mittels der verfahrbaren Ader-Zuführvorrichtung 54 entfernt (herausgezogen) und in der zweiten Invers-Crimpvorrichtung 10 positioniert. In der zweiten Invers-Crimpvorrichtung 10 erfolgt das Crimpen der inversen, nach unten geöffneten Crimpkontaktteile.Each of the in Fig. 4 Crimping devices 10, 56 shown for the simultaneous crimping of two crimp contact parts (both opened up or down). For example, by means of the wire feed device 54, two wires 14 of a four-wire line 58 are fed into the crimping boss of the conventional crimping device 56 and at the same time are provided with crimp contact parts which are open at the top. The crimped wires are then removed (pulled out) from the conventional crimping device 58 by means of the movable wire feed device 54 and positioned in the second inverse crimping device 10. In the second inverse crimping device 10, the inverse crimp contact parts which are open at the bottom are crimped.

Ein solches Crimpsystem ermöglicht das in Fig. 5A gezeigte Aufbringen von vier Crimpkontaktteilen, von denen zwei nach oben und zwei nach unten geöffnet sind, ohne dass die in der Ader-Zuführvorrichtung 54 gehaltene (geklemmte) mehradrige Leitung 60 oder einzelne Adern 14 von ihr um ihre Längsachse gedreht werden müssen. Hierdurch wird ein einfacher, effizienter und sicherer Produktionsablauf gewährleistet.Such a crimping system enables this in Figure 5A shown application of four crimp contact parts, two of which are open upwards and two downwards, without the multi-core line 60 (clamped) held in the wire feed device 54 or individual wires 14 having to be rotated by it about its longitudinal axis. This ensures a simple, efficient and safe production process.

Ein mögliches Beispiel einer herkömmlichen Crimpvorrichtung 58, wie sie in dem oben beschriebenen System verwendet werden kann, ist in Fig. 6 vereinfacht dargestellt. Wie aus Fig. 6 ersichtlich ist, ist der Crimpamboss 70 fest zur Umgebung angeordnet. Der der Crimper 74 ist über einen Träger 76 an dem Crimpamboss 70 gehalten, wobei der Crimper 74 über eine Antriebseinheit 78, die wie die Antriebseinheit 36 ausgebildet sein kann, in Richtung auf den Crimpamboss 70 zu und entgegengesetzt verfahrbar ist. Eine Zuführbandführungsvorrichtung 80 dient zum Zuführen und/oder Transport eines Zuführbandes an dem das Crimpkontaktteil 72 gehalten wird. Vor dem eigentlichen Crimpvorgang wird ein Crimpkontaktteil zwischen den Crimper und den Crimpamboss derart zugeführt, dass das Crimpkontaktteil nach oben geöffnet ist. Anschließend erfolgt ein Zuführen (Einlegen) einer Ader 82 in das geöffnete Crimpkontaktteil. Im eigentlichen Crimpvorgang wird der Crimper mittels der Antriebseinheit in Richtung auf den Crimpamboss abgesenkt, so dass das Crimpkontaktteil unter Verformung mit der Ader verbunden wird. Ein Abtrennen des Crimpkontaktteils von dem Zuführband kann vor oder gleichzeitig mit dem Crimpvorgang durch eine am Crimper vorgesehene Schneidkante erfolgen.A possible example of a conventional crimping device 58 as can be used in the system described above is shown in FIG Fig. 6 shown in simplified form. How out Fig. 6 can be seen, the crimping anvil 70 is arranged fixed to the environment. The crimper 74 is held on the crimping anvil 70 by means of a carrier 76, the crimper 74 being able to be moved towards and opposite to the crimping anvil 70 via a drive unit 78, which can be designed like the drive unit 36. A feed belt guide device 80 is used to feed and / or transport a feed belt on which the crimp contact part 72 is held. Before the actual crimping process, a crimp contact part is fed between the crimper and the crimping boss in such a way that the crimp contact part is open at the top. A wire 82 is then fed (inserted) into the open crimp contact part. In the actual crimping process, the crimper is lowered in the direction of the crimping boss by means of the drive unit, so that the crimp contact part is connected to the wire under deformation. The crimp contact part can be separated from the feed belt before or simultaneously with the crimping process by a cutting edge provided on the crimper.

Im Weiteren werden weitere mögliche Ausgestaltungen der Inverse-Crimpvorrichtung bzw. des Crimpsystems beschrieben, die, soweit nicht im Widerspruch, mit den oberen beschriebenen Merkmalen kombiniert werden können und/oder zum Austausch derselben dienen.Furthermore, further possible configurations of the inverse crimping device or of the crimping system are described which, if not in contradiction, can be combined with the features described above and / or are used to replace them.

Statt der Führung mittels der Führungsplatte 40 kann das Abtrennmesser 22 auch auf irgendeine andere geeignete Weise an dem Crimpamboss 16 in der Vertikalrichtung beweglich geführt sein. Die Anschlagpostionen des Abtrennmessers 22 können auch durch entsprechend integral ausgebildete Ausformungen in dem Abtrennmesser 22 und/oder dem Crimpamboss 16 ausgebildet werden. Zudem kann auf die obere Anschlagpostion des Abtrennmessers verzichtet werden, da diese für eine Funktion der Vorrichtung nicht relevant ist.Instead of being guided by means of the guide plate 40, the severing knife 22 can also be movably guided on the crimping boss 16 in the vertical direction in any other suitable manner. The stop positions of the severing knife 22 can also be formed by correspondingly integrally formed shapes in the severing knife 22 and / or the crimping boss 16. In addition, the upper stop position of the severing knife can be dispensed with, since this is not relevant for a function of the device.

Die Vorspannung des Abtrennmessers 22 in seine untere Position bezüglich des Crimpambosses 16 kann statt mit einer Feder auch mittels hydraulischer, elektrischer oder sonstige gearteter Aktuatoren bewirkt werden. Alternativ kann es ausreichend sein, dass das Abtrennmesser 22 durch seine eigene Gewichtskraft "vorgespannt" ist und mit dem Crimpamboss nach unten mitbewegt wird.The pretensioning of the separating knife 22 in its lower position with respect to the crimping boss 16 can also be effected by means of hydraulic, electrical or other types of actuators instead of with a spring. Alternatively, it may be sufficient for the severing knife 22 to be “biased” by its own weight and to be moved downward with the crimping boss.

Die oben beschriebene Reihenfolge (Bewegung des Crimpambosses mit Crimpkontaktteil nach unten -> Berührung Crimpkontaktteil mit Ader-> Berührung umzuformende Bereiche mit Crimperbereich usw.) kann auch abgewandelt werden, solange die Funktion des Crimpens gewährleistet ist.The sequence described above (movement of the crimp anvil with crimp contact part down -> contact crimp contact part with wire -> contact areas to be reformed with crimper area etc.) can also be modified as long as the function of the crimping is guaranteed.

Wie bereits erläutert, kann die Inverse-Crimpvorrichtung bzw. das Crimpsystem zum gleichzeitigen Crimpen mehrerer Adern ausgebildet sein. Entsprechend kann auch das Abtrennmesser eine oder mehrere Einführöffnung oder eine einzelne für das Einführen mehrerer Adern ausgebildete Einführöffnung aufweisen.As already explained, the inverse crimping device or the crimping system can be designed to crimp several wires simultaneously. Correspondingly, the severing knife can also have one or more insertion openings or a single insertion opening designed for the insertion of a plurality of wires.

Bei den in den Figuren gezeigten Beispielen werden die Crimpkontaktteile nur auf die Enden der Adern aufgecrimpt. Alternativ können diese auf beliebige Bereiche der Adern oder auch mehrere Adern aufgecrimpt werden.In the examples shown in the figures, the crimp contact parts are only crimped onto the ends of the wires. Alternatively, these can be crimped onto any area of the wire or several wires.

In den Figuren sind nur B-Crimpkontaktteile gezeigt. Es können beliebige Crimpkontaktteile, wie beispielsweise C-Crimpkontaktteile, verwendet werden.Only B crimp contact parts are shown in the figures. Any crimp contact parts, such as C-crimp contact parts, can be used.

Die Bewegung des Crimpamboss ist nicht auf eine oben-unten Bewegung beschränkt. Vielmehr kann die Bewegung in jegliche (horizontale/vertikale) Richtung erfolgen, solange eine Relativbewegung bezüglich des Crimpers (auf den Crimper zu) erreicht wird.The movement of the crimp anvil is not limited to an up-down movement. Rather, the movement can take place in any (horizontal / vertical) direction, as long as a relative movement with respect to the crimper (towards the crimper) is achieved.

Die oben beschriebenen Bewegungsabläufe bzw. Reihenfolgen, wann welches Bauteil mit welchem Bauteil in Berührung kommt oder in Interaktion treten, können selbstverständlich abgeändert werden. Beispielsweise kann die Ader schon beim Einlegen mit dem Crimpkontaktteil in Berührung kommen und/oder auch das Crimpkontaktteil bereits nach dem Zuführen desselben mit dem Crimpamboss in Kontakt stehen. Des Weiteren kann das Umformen des Crimpkontaktteils auch erst nach dem oder bei dem Abscheren desselben aus dem Zuführstreifen erfolgen. Bezugszeichenliste 10 (Invers-)Crimpvorrichtung 70 Crimpamboss 12 Crimpkontaktteil 72 Crimpkontaktteil 14 Ader 74 Crimper 16 Crimpamboss 76 Träger 18 Crimper 78 Antriebseinheit 20 umzuformende Bereiche 80 Zuführbandführungsvorrichtung 22 Abtrennmesser 82 Ader 24 Zuführband 26 Anschlag 28 Bodenplatte 30 Schraube 32 Sockel 34 Crimperbereich 36 Antriebseinheit 38 Abstützbereich 40 Führungsplatte 42 Langloch 44 Führungsbolzen 45 Feder 46 Führungsschlitz 48 Adereinführöffnung 50 Anschlagbereich 52 Zuführband-Transportvorrichtung 54 Ader-Zuführvorrichtung 56 Crimpsystem 58 herkömmliche Crimpvorrichtung 60 mehradrige Leitung The movement sequences or sequences described above, when which component comes into contact with which component or come into interaction, can of course be changed. For example, the wire can come into contact with the crimp contact part as soon as it is inserted and / or the crimp contact part can also be in contact with the crimping boss after it has been supplied. Furthermore, the shaping of the crimp contact part can also take place only after or when the crimp contact part is sheared off from the feed strip.
