Description

Die vorliegende Erfindung betrifft eine Vorrichtung der im Oberbegriff des Anspruches 1 genannten Art sowie ein Verfahren der im Oberbegriff des Anspruchs 13 genannten Art.The present invention relates to a device of the type mentioned in the preamble of claim 1 and a method of the type mentioned in the preamble of claim 13.

Es besteht vielfach die Notwendigkeit, die Adern eines Rundkabels flach nebeneinanderliegend auszubreiten, sei es, um an den Aderenden Kontaktschuhe anzubringen oder um an das Rundkabel einen Flachstecker anzuschlagen. In beiden Fällen müssen die Adern nebeneinanderliegend und im allgemeinen mit vorgegebenen gegenseitigen Abständen angeordnet und in dieser Anordnung festgehalten werden.There is often a need to spread the wires of a round cable flat next to each other, be it to attach contact shoes to the wire ends or to attach a flat connector to the round cable. In both cases, the wires must be arranged side by side and generally with predetermined mutual distances and held in this arrangement.

Die DE-C-24 39 171 zeigt bereits eine Vorrichtung der im Oberbegriff des Anspruches 1 genannten Art, bei welcher die Adern des Rundkabels mittels eines in Längsrichtung des Kabels beweglichen Niederhalters an eine Auflageplatte angedrückt bzw. in in der Auflageplatte ausgebildete Aufnahmenuten eingedrückt und festgehalten werden. Um sicherzustellen, daß die Adern bei diesem Vorgang in die ihnen zugeordneten Aufnahmenuten gedrückt werden, führt der Niederhalter zusätzlich quer zur Richtung der Adern gerichtete Vibrationsbewegungen aus. Dadurch, daß für die Zustellung des Niederhalters, für dessen Bewegung in Längsrichtung des Kabels und die Vibrationsbewegung quer zum Kabel jeweils eigene Antriebe vorgesehen sein müssen, wird diese Vorrichtung äußerst aufwendig und deshalb teuer. Vor allem dann, wenn es beabsichtigt ist, die Adern des Rundkabels zu zwei zueinander parallelen Reihen zu ordnen, um sie an einen zweireihigen Flachstecker anzuschließen, führt das bekannte Konstruktionsprinzip zu einem untragbaren konstruktiven und fertigungstechnischen Aufwand.DE-C-24 39 171 already shows a device of the type mentioned in the preamble of claim 1, in which the wires of the round cable are pressed onto a support plate by means of a hold-down device movable in the longitudinal direction of the cable or in the support plate trained grooves are pressed in and held. In order to ensure that the wires are pressed into the receiving grooves assigned to them during this process, the hold-down device also carries out vibratory movements transverse to the direction of the wires. Characterized in that for the delivery of the hold-down, for its movement in the longitudinal direction of the cable and the vibration movement across the cable each own drives must be provided, this device is extremely complex and therefore expensive. Especially when it is intended to arrange the wires of the round cable into two parallel rows in order to connect them to a two-row flat connector, the known design principle leads to an unbearable design and manufacturing effort.

Es ist die Aufgabe der vorliegenden Erfindung, eine Vorrichtung der im Oberbegriff des Anspruches 1 genannten Art mit einem wesentlich einfacheren Aufbau zu schaffen, so daß mit tragbarem technischen Aufwand beispielsweise auch eine Anordnung der Adern in zwei zueinander parallelen Reihen möglich wird.It is the object of the present invention to provide a device of the type mentioned in the preamble of claim 1 with a much simpler structure, so that, for example, an arrangement of the wires in two rows parallel to one another is possible with portable technical outlay.

Diese Aufgabe ist erfindungsgemäß durch die im Kennzeichen des Anspruches 1 enthaltenen Merkmale gelöst.This object is achieved by the features contained in the characterizing part of claim 1.

Der Niederhalter ist als flexibles Band ausgebildet, welches sich von einer Seite her quer über das mehr oder weniger aufgefächerte Aderbündel des Rundkabels legt und deshalb die Adern nacheinander einzeln erfaßt und nebeneinanderliegend auf die Auflageplatte drückt. Das Andrücken bzw. Abheben des Niederhalters läßt sich durch eine einfache Abroll- bzw. Aufrollbewegung des flexiblen Bandes darstellen, die mit einfachen technischen Mitteln bewerkstelligt werden kann, wie anhand eines Ausführungsbeispieles genauer ausgeführt wird.The hold-down device is designed as a flexible band, which is laid from one side across the more or less fanned out wire bundle of the round cable and therefore seizes the wires one by one and presses them side by side onto the support plate. The pressing or lifting of the hold-down device can be represented by a simple rolling or rolling movement of the flexible band, which can be accomplished with simple technical means, as will be explained in more detail using an exemplary embodiment.

Um die Adern mit vorgegebenen seitlichen Abständen zueinander auf der Auflageplatte zu ordnen und zu halten, ist in einer Ausgestaltung der Erfindung vorgesehen, daß die Auflageplatte eine glatte Auflagefläche hat und daß das flexible Band an seiner der Auflageplatte zugewandten Seite mit Ausnehmungen zur Aufnahme je einer Ader versehen ist. Die Ausnehmungen lassen sich so gestalten, daß sie beim Auflegen des flexiblen Bandes jeweils genau eine Ader erfassen, so daß die Adern mit den Abständen der Ausnehmungen entsprechenden Abständen seitlich nebeneinander auf der Auflageplatte liegen und gehalten werden.In order to arrange and hold the wires with predetermined lateral distances from one another on the support plate, it is provided in one embodiment of the invention that the support plate has a smooth contact surface and that the flexible band on its side facing the support plate has recesses for receiving one wire each is provided. The recesses can be designed in such a way that when the flexible band is placed on them, they each capture exactly one wire, so that the wires with the spacings of the recesses correspond laterally to one another on the support plate and are held.

Eine mechanisch sehr einfache Konstruktion ergibt sich, wenn erfindungsgemäß das flexible Band mit einem Ende bezüglich der Auflageplatte fest angeordnet ist und dem flexiblen Band ein quer zu den Adern über die Auflageplatte verstellbarer Ab- und Aufrollmechanismus zugeordnet ist. Für einen derartigen Ab- und Aufrollmechanismus sind unterschiedliche Konstruktionen denkbar. Bei einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, daß das flexible Band an seiner der Auflageplatte abgewandten Seite ein Längsführungsprofil hat, welches in ein entsprechendes Aufnahmeprofil einer quer zu den Adern ausgerichteten, parallel zur Auflageplatte verstellbaren Führungsschiene eingreift, und daß die Führungsschiene zumindest einen zur Auflageplatte parallen und zumindest einen daran anschließenden, zur Aufnahmeplatte divergierend verlaufenden Abschnitt hat. Der in dem parallelen Abschnitt befindliche Teil des flexiblen Bandes befindet sich in der auf die Auflageplatte aufgelegten Stellung, während sich der im divergierenden Abschnitt befindliche Teil des flexiblen Bandes in einer abgehobenen Stellung befindet, wie anhand des Ausführungsbeipieles noch genauer dargelegt wird. Auf diese Weise läßt sich das flexible Band durch eine einfache Linearbewegung der Führungsschiene auf die Auflageplatte auflegen bzw. von dieser abheben.A mechanically very simple construction results if, according to the invention, the flexible band is fixedly arranged with one end with respect to the support plate and the unwinding and reeling mechanism, which is adjustable transversely to the wires via the support plate, is assigned to the flexible band. Different constructions are conceivable for such a roll-off and roll-up mechanism. In a preferred embodiment of the invention it is provided that the flexible band on its side facing away from the support plate has a longitudinal guide profile which engages in a corresponding receiving profile of a guide rail which is oriented transversely to the wires and is adjustable parallel to the support plate, and that the guide rail has at least one to the support plate parallel and has at least one adjoining, diverging section to the receiving plate. The part of the flexible band located in the parallel section is in the position placed on the support plate, while the part of the flexible band located in the diverging section is in a raised position, as shown in FIG of the execution example is explained in more detail. In this way, the flexible band can be placed on or removed from the support plate by a simple linear movement of the guide rail.

Der Niederhalter ist vorzugsweise durch ein Gliederband gebildet. Dabei entspricht die Gliederteilung des Gliederbandes dem gewünschten gegenseitigen Abstand der Adern auf der Auflageplatte. Die Glieder haben an ihrer der Auflageplatte zugewandten Seite jeweils ein der Außenkontur einer Ader entsprechendes Aufnahmeprofil und an ihrer anderen Seite ein dem Aufnahmeprofil der Führungsschiene entsprechendes Führungsprofil. Das Giederband ist vorzugsweise einstückig aus Kunststoff gefertigt, wobei die Verbindung der Glieder miteinander über sogenannte Filmscharniere hergestellt ist.The hold-down device is preferably formed by a link belt. The division of the link band corresponds to the desired mutual spacing of the wires on the support plate. The links each have a receiving profile corresponding to the outer contour of a wire on their side facing the support plate and a guide profile corresponding to the receiving profile of the guide rail on their other side. The link belt is preferably made in one piece from plastic, the connection of the links to one another being established via so-called film hinges.

In einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die Führungsschiene in einzelnen, der Gliederteilung entsprechenden Schritten verstellbar ist. Dadurch wird es einer Bedienungsperson erleichtert, das Erfassen der einzelnen Adern durch die Glieder manuell zu unterstützen.In a further embodiment of the invention it is provided that the guide rail can be adjusted in individual steps corresponding to the division of the limbs. This makes it easier for an operator to manually support the detection of the individual wires by the links.

Häufig ist es erforderlich, die Adern eines Rundkabels zu zwei zueinander parallelen, übereinanderliegenden Reihen zu ordnen. Für einen derartigen Fall ist gemäß einer weiteren Ausgestaltung der Erfindung vorgesehen, daß zwei Halteschablonen mit zwei zueinander parallelen Auflageplatten vorgesehen sind, deren Auflageflächen voneinander abgewandt sind. Diese Anordnung erlaubt es, in jeder der Halteschablonen eine Aderreihe zu bilden. Wie anhand eines Ausführungsbeispieles dargelegt wird, ist eine konstruktive Lösung möglich, die es erlaubt, diese beiden Aderreihen gleichzeitig zu bilden und in ihrer vorgegebenen gegenseitigen Konfiguration zu halten.It is often necessary to arrange the cores of a round cable into two parallel rows, one above the other. For such a case, it is provided according to a further embodiment of the invention that two holding templates are provided with two mutually parallel support plates, the support surfaces of which face away from each other. This arrangement makes it possible to form a row of wires in each of the holding templates. As will be explained with the aid of an exemplary embodiment, a constructive solution is possible which allows these two wire rows to be formed simultaneously and in to maintain their predetermined mutual configuration.

In weiteren Ausgestaltungen der Erfindung sind jeder Halteschablone Ablängeinrichtungen sowie Einrichtungen zum Anschlagen eines Flachsteckers an die abgelängten Aderenden zugeordnet. Für den Fall, daß die Vorrichtung in der beschriebenen Weise zwei Halteschablonen aufweist, können die Ablängeinrichtungen sowie die Anschlageinrichtungen so ausgebildet sein, daß die beiden Aderreihen jeweils gleichzeitig verarbeitet werden.In further refinements of the invention, each holding template is assigned cutting devices and devices for attaching a tab to the cut wire ends. In the event that the device has two holding templates in the manner described, the cutting-to-length devices and the stop devices can be designed such that the two wire rows are each processed simultaneously.

Ein auf die erfindungsgemäße Vorrichtung abgestimmtes Verfahren ist durch die im Anspruch 13 enthaltenen Merkmale gekennzeichnet. Dabei werden die Aderenden des Rundkabels in aufeinanderfolgenden Verfahrensschritten vereinzelt, auf einer Halteplatte ausgerichtet und gehalten und unter Beibehaltung dieser Einspannung abgelängt sowie an einen Flachstecker angeschlagen.A method matched to the device according to the invention is characterized by the features contained in claim 13. The wire ends of the round cable are separated in successive process steps, aligned and held on a holding plate and cut to length while maintaining this clamping and attached to a flat connector.

Eine weitere Ausgestaltung des erfindungsgemäßen Verfahrens erlaubt es darüber hinaus, die Adern eines Rundkabels zu zwei parallelen Reihen zu ordnen, sie in dieser Konfiguration festzuhalten und sie dann gleichzeitig abzulängen sowie mit einem Flachstecker zu verbinden, wie anhand eines Ausführungsbeispieles im einzelnen dargelegt wird.A further embodiment of the method according to the invention also allows the wires of a round cable to be arranged in two parallel rows, held in this configuration and then cut to length and connected with a flat plug, as will be explained in detail using an exemplary embodiment.

Die in Fig. 1 dargestellte Vorrichtung umfaßt im wesentlichen ein Vorrichtungsgehäuse 2, an welchem zwei Auflageplatten 4, 6 angeordnet sind. Die Auflageplatten 4 bzw. 6 sind in Richtung der Doppelpfeile 8 bzw. 10 verstellbar am Vorrichtungsgehäuse 2 gelagert. Sie können durch einen nicht dargestellten Verstellmechanismus symmetrisch zur Mittellinie 12 aufeinander zu bzw. voneinander weg bewegt werden.The device shown in Fig. 1 essentially comprises a device housing 2, on which two support plates 4, 6 are arranged. The support plates 4 and 6 are adjustably mounted on the device housing 2 in the direction of the double arrows 8 and 10. They can be moved towards or away from each other symmetrically to the center line 12 by an adjustment mechanism, not shown.

An den Auflageplatten 4 bzw. 6 sind Zahnvorsprünge 14 bzw. 16 (siehe auch Fig. 2) ausgebildet, die jeweils in an der gegenüberliegenden Auflageplatte vorgesehene, zugeordnete Ausnehmungen 18 bzw. 20 eingreifen, wenn die beiden Auflageplatten 4 bzw. 6 ihre in den Fig. 5 und 6 dargestellte, aneinanderliegende Stellung einnehmen. Die Zahnvorsprünge 14, 16 und die zugeordneten Ausnehmungen 18, 20 dienen zur lagegenauen Fixierung der beiden Auflageplatten 4, 6 zueinander.Toothed projections 14 and 16 (see also FIG. 2) are formed on the support plates 4 and 6, respectively, which engage in the corresponding recesses 18 and 20 provided on the opposite support plate when the two support plates 4 and 6 insert their into the Fig. 5 and 6, shown in the adjacent position. The tooth projections 14, 16 and the associated recesses 18, 20 serve to fix the two support plates 4, 6 to one another in the correct position.

Die der Mittellinie 12 abgewandten Außenseiten der Auflageplatten 4 bzw. 6 bilden jeweils Auflageflächen 22 bzw. 24, auf die die Adern 26 bzw. 28 eines Rundkabels 30 aufgelegt werden können. Zu diesem Zweck werden die Adern 26, 28 des Rundkabels 30 grob vorsortiert und über die Auflageflächen 22 bzw. 24 gebracht.The outer sides of the support plates 4 and 6 facing away from the center line 12 each form support surfaces 22 and 24, on which the wires 26 and 28 of a round cable 30 can be placed. For this purpose, the wires 26, 28 of the round cable 30 are roughly pre-sorted and brought over the contact surfaces 22 and 24, respectively.

Um die Adern 26 bzw. 28 an die zugeordneten Auflageflächen 22 bzw. 24 anzudrücken und mit vorgegebenem seitlichen Abstand zu halten, sind den Auflageplatten 4 bzw. 6 je ein Niederhalter 32 bzw. 34 zugeordnet, die im folgenden anhand des Niederhalters 32 genauer beschrieben werden.

Die einzelnen Glieder 38 sind in an sich bekannter Weise über verdünnte Materialstege, sogenannte Filmscharniere miteinander verbunden. Die einzelnen Glieder 38 haben an ihren der Auflageplatte 4 zugewandten Seiten Ausnehmungen 40 zur Aufnahme je einer Ader 26. Wie Fig. 1 erkennen läßt, sind diese Ausnehmungen 40 so geformt, daß sie an einer Seite einen keilförmig nach unten weisenden Steg 42 bilden, welcher jeweils zwischen zwei eng aneinanderliegende Adern 26 greift und diese trennt, so daß jede der Ausnehmungen 40 genau eine Ader aufnimmt.In order to press the wires 26 and 28 against the associated support surfaces 22 and 24 and to hold them with a predetermined lateral distance, the hold-down plates 4 and 6 are each assigned a hold-down device 32 and 34, which are described in more detail below with the aid of the hold-down device 32 . The hold-down device 32 comprises a flexible band 36 designed as a link band; this is made, for example, in one piece from an elastic plastic. The individual links 38 are connected to one another in a manner known per se via thinned material webs, so-called film hinges. The individual members 38 have on their sides facing the support plate 4 recesses 40 for receiving one core 26 each. As can be seen in FIG. 1, these recesses 40 are shaped such that they form a wedge-shaped downward web 42 on one side, which each engages between two closely spaced wires 26 and separates them, so that each of the recesses 40 receives exactly one wire.

An der der Auflageplatte 4 abgewandten Seite ist jedes der Glieder 38 mit einem T-förmigen Führungsprofil 44 versehen, welches in ein entsprechendes Aufnahmeprofil 46 einer quer zu den Adern 26 ausgerichteten Führungsschiene 48 eingreifen kann. Die Führungsschiene 48 ist parallel zur Auflagefläche 22 in Richtung des Doppelpfeiles 50 verstellbar. An ihrer der Auflageplatte 4 zugewandten Seite hat die Führungsschiene 48 einen zur Auflagefläche 22 parallelen Abschnitt 52 und einen daran anschließenden, zur Auflagefläche 22 divergierend verlaufenden Abschnitt 54.On the side facing away from the support plate 4, each of the links 38 is provided with a T-shaped guide profile 44 which fits into a corresponding receiving profile 46 a guide rail 48 aligned transversely to the wires 26 can engage. The guide rail 48 is adjustable parallel to the bearing surface 22 in the direction of the double arrow 50. On its side facing the support plate 4, the guide rail 48 has a section 52 which is parallel to the support surface 22 and an adjoining section 54 which diverges from the support surface 22.

Der in Fig. 1 untere Niederhalter 34 ist bezüglich der Mittellinie 12 symmetrisch zum oberen Niederhalter 32 ausgebildet und umfaßt ein flexibles Band 56 sowie eine Führungsschiene 58, die gemeinsam mit der oberen Führungsschiene 48 in Richtung des Doppelpfeiles 60 verstellbar ist. Die flexiblen Bänder 36 bzw. 56 sind jeweils mit ihren in Fig. 1 linken Enden am Vorrichtungsgehäuse 2 befestigt.The lower hold-down device 34 in FIG. 1 is formed symmetrically with respect to the center line 12 to the upper hold-down device 32 and comprises a flexible band 56 and a guide rail 58 which can be adjusted together with the upper guide rail 48 in the direction of the double arrow 60. The flexible bands 36 and 56 are each fastened to the device housing 2 with their left ends in FIG. 1.

Die Funktion der in den Fig. 1 und 2 dargestellten Vorrichtung ist folgende:The function of the device shown in FIGS. 1 and 2 is as follows:

In der Ausgangsstellung nehmen die beiden Auflageplatten 4 bzw. 6 die in den Fig. 1 bis 4 dargestellte, am weitesten voneinander entfernte Lage ein. Die Führungsschienen 48 bzw. 58 sind soweit in das Vorrichtungsgehäuse 2 eingefahren, daß das jeweils innere, dem Vorrichtungsgehäuse 2 nächste Glied der flexiblen Bänder 36 bzw. 56 sich in dem divergierenden Abschnitt 54 der zugeordneten Führungsschiene 48 bzw. 58 befindet; dadurch sind die flexiblen Bänder 36 bzw. 56 von den zugeordneten Auflageplatten 4 bzw. 6 abgehoben.In the starting position, the two support plates 4 and 6 assume the most distant position shown in FIGS. 1 to 4. The guide rails 48 and 58 have been inserted into the device housing 2 to such an extent that the respective inner link of the flexible bands 36 and 56 closest to the device housing 2 is located in the diverging section 54 of the associated guide rail 48 and 58; as a result, the flexible bands 36 and 56 are lifted off the associated support plates 4 and 6, respectively.

Die Adern 26 bzw. 28 werden mehr oder weniger vorsortiert über die zugeordneten Auflageflächen 22 bzw. 24 gebracht. Sodann werden die Führungsschienen 48 bzw. 58 in Fig. 1 nach rechts verstellt, wobei die Glieder 38 der flexiblen Bänder 36 bzw. 56 nacheinander entlang dem divergierenden Abschnitt 54 in den parallelen Abschnitt 52 gleiten und sich der zugeordneten Auflageplatte 4 bzw. 6 nähern. Dabei ergreifen sie jeweils eine der Adern, drücken diese an die zugeordnete Auflagefläche 22 bzw. 24 an und halten sie auf dieser fest, bis alle Adern erfaßt sind.The wires 26 and 28 are more or less pre-sorted over the assigned contact surfaces 22 and 24. Then the guide rails 48 and 58, respectively 1 to the right, the links 38 of the flexible bands 36 and 56 sliding in succession along the diverging section 54 into the parallel section 52 and approaching the associated support plate 4 and 6, respectively. They each take one of the wires, press it against the associated support surface 22 or 24 and hold it there until all the wires are gripped.

In einem zweiten Verfahrensschritt werden die Adern 26 bzw. 28 abgelängt (Fig. 3). Dazu wird an der Seite der Vorrichtung, an der die freien Enden der Adern 26, 28 über die zugeordneten Auflageplatten 4, 6 überstehen , eine Ablängeinrichtung angeordnet, die als Ganzes mit 62 bezeichntet ist. Sie besteht aus einem zwischen die beiden Reihen der Adern 26 bzw. 28 einzuführenden, beiden Reihen gemeinsamen Gegenmesser 64 sowie zwei Schneidmessern 66 bzw. 68. Zum Ablängen wird das in Fig. 3 obere Schneidmesser 66 in Richtung des Pfeiles 70 nach unten und das untere Schneidmesser 68 in Richtung des Pfeiles 72 nach oben verstellt, wobei diese Schneidmesser 66, 68 im Zusammenwirken mit dem Gegenmesser 64 die Adern 26, 28 auf gleiche Länge abschneiden. Nach Entfernen der Ablängeinrichtung 62 können die freien Enden der Adern 26, 28 weiterverarbeitet werden.In a second process step, the wires 26 and 28 are cut to length (FIG. 3). For this purpose, a cutting device is arranged on the side of the device on which the free ends of the wires 26, 28 protrude beyond the associated support plates 4, 6, which is identified as a whole by 62. It consists of a counter knife 64 to be inserted between the two rows of wires 26 and 28, two rows common, and two cutting knives 66 and 68. For cutting to length, the upper cutting knife 66 in FIG. 3 is downward in the direction of arrow 70 and the lower one Cutting knife 68 is adjusted upward in the direction of arrow 72, these cutting knives 66, 68, in cooperation with counter knife 64, cutting the wires 26, 28 to the same length. After the cutting device 62 has been removed, the free ends of the wires 26, 28 can be processed further.

In den Fig. 4 und 5 sind Verfahrensschritte dargestellt, in denen die freien Enden der Adern 26, 28 an einen Flachstecker 74 angeschlagen werden. Der Flachstecker 74 besteht im wesentlichen aus einem Steckergehäuse 76, in welchem zwei Reihen von Kontaktelementen 78, 80 in jeweils einer der Anzahl der Adern 26 bzw. 28 entsprechenden Anzahl vorgesehen sind. Die Kontaktelemente 78, 80 enden an der Rückseite des Flachsteckers 74 in rechtwinklig abgebogenen Schneidkontakten 82, 84; wie Fig. 4 zeigt, stehen diese Schneidkontakte 82, 84 bei zwischen die Adern 26 bzw. 28 eingeführtem Flachstecker 74 senkrecht zu diesen Adern. Der seitliche Abstand der Kontaktelemente 78, 80 entspricht dem seitlichen Abstand der auf den Auflageplatten 4 bzw. 6 aufliegenden Adern, wobei zum Zwecke einer besseren Unterbringung der Schneidkontakte 82 bzw. 84 diese in an sich bekannter Weise hintereinander gestaffelt sind, wie aus Fig. 4 ersichtlich ist.4 and 5 process steps are shown in which the free ends of the wires 26, 28 are struck on a tab 74. The flat connector 74 essentially consists of a connector housing 76, in which two rows of contact elements 78, 80 are provided, each in a number corresponding to the number of wires 26 and 28, respectively. The contact elements 78, 80 end at the rear of the flat connector 74 in right-angled cutting contacts 82, 84; as 4 shows, these cutting contacts 82, 84 are perpendicular to these wires when the flat plug 74 is inserted between the wires 26 and 28, respectively. The lateral spacing of the contact elements 78, 80 corresponds to the lateral spacing of the wires resting on the support plates 4 and 6, respectively, for the purpose of better accommodating the cutting contacts 82 and 84, these are staggered in a manner known per se, as shown in FIG. 4 can be seen.

Auf die freien Enden der Adern 26, 28 werden in einem weitern Verfahrensschritt jeweils zum Flachstecker 74 gehörende Halteleisten 86 bzw. 88 aufgelegt, die mit entsprechend der Anordnung der Schneidkontakte 82 bzw. 84 angeordneten Ausnehmungen 90 bzw. 92 versehen sind.In a further process step, retaining strips 86 and 88 belonging to the flat connector 74 are placed on the free ends of the wires 26, 28 and are provided with recesses 90 and 92 arranged in accordance with the arrangement of the cutting contacts 82 and 84, respectively.

Wie Fig. 5 zeigt, wirkt die Vorrichtung in einem weiteren Verfahrensschritt mit einer Anschlageinrichtung zusammen, die als Ganzes mit 94 bezwichnet wird. Diese umfaßt im Wesentlichen zwei Preßstempel 96 bzw. 98, die symmetrisch zur Mittellinie 12 in Richtung der Doppelpfeile 100 bzw. 102 verstellbar sind. Durch diese Preßstempel 96, 98 werden die zugeordneten Halteleisten 86 bzw. 88 aufeinander zu gedrückt, wobei die Adern 26 bzw. 28 in die zugeordneten Schneidkontakte 82 bzw. 84 gedrückt und mit diesen kontaktiert werden. Wie Fig. 5 erkennen läßt, werden die Preßstempel 96 bzw. 98 gleichzeitig mit den jeweils aus einer Auflageplatte und einem Niederhalter bestehenden Halteschablonen aufeinander zu verstellt.As shown in FIG. 5, in a further method step the device interacts with a stop device, which as a whole is dubbed 94. This essentially comprises two press rams 96 and 98, which can be adjusted symmetrically to the center line 12 in the direction of the double arrows 100 and 102, respectively. The associated holding strips 86 and 88 are pressed towards one another by these press punches 96, 98, the wires 26 and 28 being pressed into the associated cutting contacts 82 and 84 and being contacted with them. As can be seen in FIG. 5, the press punches 96 and 98 are adjusted towards one another simultaneously with the holding templates each consisting of a support plate and a hold-down device.

In einem weiteren, in Fig. 6 schematisch angedeuteten Verfahrensschritt werden die flexiblen Bänder 36 bzw. 56 durch Verstellen der Führungsschienen 48 bzw. 58 in Fig. 1 nach links von den zugeordneten Halteplatten 4 bzw. 6 abgehoben, so daß die Adern 26 bzw. 28 freigegeben werden. Das Rundkabel 30 mit dem daran angeschlageenen Flachstecker 74 kann dann in Fig. 1 nach rechts aus der Vorrichtung entnommen werden.In a further process step, indicated schematically in FIG. 6, the flexible bands 36 and 56 are moved to the left of the assigned holding plates 4 by moving the guide rails 48 and 58 in FIG. 1 or 6 lifted off so that the wires 26 and 28 are released. The round cable 30 with the tab 74 attached to it can then be removed from the device to the right in FIG. 1.
