Die Erfindung betrifft eine Vorrichtung zum Umformen von Leitungsummantelungen mit einem Aufnähmeelement , das mindestens einen Einlegeschlitz aufweist, in welchen eine Einzelleitung einpreßbar ist, und einem Eindrückelement, welches mittels eines Betätigungselementes auf das Aufnähmeelement zu bewegbar ist und mindestens ein mit einem Einlegeschlitz zusammenwirkendes Stempelblatt aufweist, welches bei Betätigung des Eindrückelementes zumindest teilweise in den Einlegeschlitz eintaucht und ein Verfahren zum Umformen von Leitungsummantelungen mit Hilfe einer solchen Vorrichtung.The invention relates to a device for reshaping cable sheathing with a receiving element which has at least one insertion slot into which a single line can be pressed, and a pressing-in element which can be moved towards the receiving element by means of an actuating element and has at least one stamping sheet interacting with an insertion slot. which at least partially dips into the insertion slot when the push-in element is actuated and a method for reshaping cable sheaths with the aid of such a device.
Aus CH 660 935 A5 ist ein Werkzeug und dessen Verwendung zum einfachen und schnellen Andrahten eines Steckers mit Schneid- steckanschluß bekannt. Im wesentlichen besteht das Werkzeug aus einer Handzange, an welcher ein Gesenkteil an einem ar- beitsseitigen Hebelende und ein Stempelkopf an einem anderen arbeitsseitigen Hebelende befestigt ist. Des weiteren weist der Gesenkteil eine zum Einschieben eines Steckers bestimmte Kammer sowie Einlegeschlitze für anzuschließende Drahtenden auf. Der Stempelkopf trägt auf die Einlegeschlitze ausgerichtete Stempelblätter, so daß die Stempelblätter bei Betätigung der Zangengriffe in die Einlegeschlitze eindringen und die Drahtenden in die Klemmschneide der Schneidsteckanschlüsse des Steckers pressen.From CH 660 935 A5 a tool and its use for simple and quick wire connection of a plug with a plug-in connector is known. The tool essentially consists of a pair of pliers on which a die part is attached to a working lever end and a punch head to another working lever end. Furthermore, the die part has a chamber intended for inserting a plug and insertion slots for wire ends to be connected. The stamp head carries stamp sheets aligned with the insertion slots, so that the stamp sheets penetrate into the insertion slots when the pliers handles are actuated and press the wire ends into the clamping cutting edge of the cutting plug connections of the plug.
In vielen Anwendungsgebieten ist es wünschenswert, daß sowohl NF-Kabel als auch HF-Kabel an Schneidklemmkontakte ein und demselben IDC-Steckverbinders angeschlagen und mit dem selben Konfektionierungswerkzeug gleichzeitig verarbeitet werden können. Ein Problem in dieser Hinsicht stellen die unterschiedlichen Durchmesser von NF- und HF-Kabeln dar. Dies führt beim Anschlagen von HF-Einzelleitungen an einen gemein¬ samen IDC-Steckverbinder zu nachteiligen Aufstauchungen ihrer Leitungsummantelungen. Neben negativen Auswirkungen auf die Qualität der elektrischen Verbindungen ist bei aus mehreren Kontaktlamellen bestehenden Steckverbindern die Stapelbarkeit der in einem gemeinsamen Steckergehäuse untergebrachten Kontaktlamellen aufgrund überquellender Leitungsummantelungen eingeschränkt. Um dieses Problem bei HF-Einzelleitungen zu umgehen, werden vielfach die Leitungsummantelungen abisoliert und anschließend spezielle Crimpschläuche montiert. Des weiteren ist es sogar oft erforderlich, für HF-Einzelleitungen komplett andere Steckverbinder zu verwenden, wobei separate Konfektionierungswerkzeuge für die HF-Einzelleitungen benötigt werden.In many areas of application, it is desirable that both NF cables and HF cables can be attached to insulation displacement contacts of the same IDC connector and processed at the same time with the same assembly tool. The different diameters of LF and HF cables pose a problem in this regard. This rt fo h at A nschlagen RF individual lines to a common ¬ seed IDC connectors to their adverse Aufstauchungen conductor sheaths. In addition to negative effects on the quality of the electrical connections, in the case of connectors consisting of a plurality of contact blades, the stackability of the contact blades accommodated in a common connector housing is restricted due to overflowing cable sheaths. In order to avoid this problem with individual HF lines, the cable sheaths are stripped in many cases and then special crimping tubes are installed. Furthermore, it is often even necessary to use completely different plug connectors for HF individual lines, separate assembly tools being required for the HF individual lines.
Der Erfindung liegt das Ziel zugrunde, eine Vorrichtung zu schaffen, welche eine schnelle und einfache Vorverarbeitung von HF-Einzelleitungen ermöglicht, so daß sowohl NF- als auch HF-Einzelleitungen unter Gewährleistung einer optimalen Qua- lität für elektrische Verbindungen an ein und demselben IDC-The invention is based on the objective of creating a device which enables rapid and simple preprocessing of individual HF lines, so that both NF and HF individual lines, while ensuring optimum quality for electrical connections to one and the same IDC,
Steckverbinder angeschlagen werden können.Connectors can be struck.
Erfindungsgemäß wird dieses Ziel dadurch erreicht, daß jeder Einlegeschlitz an zwei gegenüberliegenden Seiten in Längs- richtung ausgebildete scharfkantige Schneidzonen aufweist.According to the invention, this aim is achieved in that each insertion slot has sharp-edged cutting zones formed on two opposite sides in the longitudinal direction.
Die erfindungsgemäße Vorrichtung ermöglicht die Umformung der Leitungsummantelungen bei HF-Einzelleitungen durch seitliches Abschneiden eines Teils der Leitungsummantelungen, wobei die Form der Leitungsummantelungen derart optimiert ist, daß eine gemeinsame und gleichzeitige Verarbeitung von NF- und HF-Einzelleitungen bei IDC-Steckverbindern problemlos möglich ist. Die Umformung der Leitungsummantelungen ist vorteilhafterweise auf in Schneidklemmanschlüsse einzudrückende Abschnitte der HF-Einzelleitungen beschränkt. Somit werden beim Anschlagen von NF- und HF-Einzelleitungen an einen gemeinsamen IDC- Steckverbinder weder spezielle Schneidklemmkontakte noch se- parate Konfektionierungswerkzeuge für die HF-Einzelleitungen benötigt. Ebenso erübrigt sich die Verwendung zusätzlicher Crimpschlauche für HF-Einzelleitungen. Daher entfallen etwaige Kosten für Montagehilfsmittel bei gleichzeitiger Reduktion des Montageaufwandes. Nicht zuletzt ermöglicht die erfindungsgemäße Umformvorrichtung eine optimierte Qualität für Schneidklemmverbindungen zu realisieren.The device according to the invention makes it possible to reshape the cable sheaths in the case of HF individual lines by cutting off a part of the line sheaths at the side, the shape of the line sheaths being optimized in such a way that joint and simultaneous processing of NF and HF individual lines is easily possible with IDC connectors. The reshaping of the cable sheathing is advantageously limited to sections of the HF individual lines to be pressed into insulation displacement connections. This means that when NF and HF individual cables are attached to a common IDC connector, neither special insulation displacement contacts nor ready assembly tools for the HF single lines required. Likewise, there is no need to use additional crimp tubing for HF individual lines. Therefore, any costs for assembly aids are eliminated with a simultaneous reduction in assembly costs. Last but not least, the forming device according to the invention enables optimized quality for insulation displacement connections to be realized.
Um die erfindungsgemäße Umformvorrichtung in einer vorteil- haften Ausgestaltung auch für den Feldeinsatz bereitzustellen, sind das Aufnahmeelement und das Eindrückelement an einer zangenartigen Vorrichtung befestigt. Dabei ist das Auf- nahmeelement an einem Basisgestell der zangenartigen Vorrichtung angebracht . Ferner ist ein Hebelarm an einem ersten Ende schwenkbar am Basisgestell gelagert, wobei das Eindrückelement am zweiten Ende des Hebelarmes befestigt ist. Darüber hinaus ist der Hebelarm über einen auf ein Betätigungselement einwirkenden Handgriff auslenkbar.In order to also provide the shaping device according to the invention in an advantageous embodiment for field use, the receiving element and the pressing-in element are fastened to a forceps-like device. The receiving element is attached to a base frame of the tongs-like device. Furthermore, a lever arm is pivotally mounted on the base frame at a first end, the push-in element being fastened to the second end of the lever arm. In addition, the lever arm can be deflected via a handle acting on an actuating element.
In vorteilhafter Ausgestaltung sind die Einlegeschlitze in ihrem äußeren Bereich verbreitert, wodurch Fixierungsorgane für die umzuformenden Einzelleitungen gebildet sind. Hierdurch wird insbesondere ein seitliches Verrutschen der Einzelleitungen beim Einpressen der Einzelleitungen in die Schneidzonen der Einlegeschlitze vermieden. Des weiteren sind die Stempelblätter an ihren den Einlegeschlitzen zugewandten Kanten vorzugsweise konkav geformt, um eine optimale Führung der Einzelleitungen beim Einpressen in die Schneidzonen der Einlegeschlitze zu erreichen.In an advantageous embodiment, the insertion slots are widened in their outer area, thereby forming fixing elements for the individual lines to be formed. This in particular prevents the individual lines from slipping sideways when the individual lines are pressed into the cutting zones of the insertion slots. Furthermore, the stamp sheets are preferably concave at their edges facing the insertion slots in order to achieve optimum guidance of the individual lines when pressed into the cutting zones of the insertion slots.
Vorteilhafterweise sind das Aufnähmeelement und das Eindrük- kelement am Basisgestell und am Hebelarm mittels lösbarer Befestigungsmittel angebracht, so daß die beiden Vorrichtungs- elemente schnell und einfach gegen entsprechende Werkzeugkom- ponenten zum Anschlagen von Einzelleitungen an IDC-Kontakte ausgetauscht werden können. Dies bietet den Vorteil, daß eine durch Basisgestell, Hebelarm, Betätigungselement und Hand- griff gebildete IDC-Feldzange nicht nur für ein Umformwerk- zeug verwendet werden kann, sondern auch für ein Anschlagwerkzeug.The receiving element and the push-in element are advantageously attached to the base frame and on the lever arm by means of releasable fastening means, so that the two device elements can be quickly and easily exchanged for corresponding tool components for attaching individual lines to IDC contacts. This offers the advantage that a base frame, lever arm, actuating element and hand handle formed IDC field forceps can not only be used for a forming tool, but also for a stop tool.
Das Verfahren zum Umformen von Leitungsummantelungen gestaltet sich mit Hilfe des Umformwerkzeuges für den Feldeinsatz denkbar einfach. Zunächst werden die Einzelleitungen in die Einlegeschlitze des Aufnahmeelementes eingelegt, und der Hebelarm wird soweit eingeschwenkt, bis die Stempelblätter auf den Einzelleitungen aufliegen. Im Anschluß daran erfolgt ein Einschwenken des Betätigungselementes mit Hilfe des Handgriffs. Im folgenden wird mit Hilfe des Handgriffs auf den Hebelarm und die Stempelblätter Druck ausgeübt, so daß die Leitungsummantelungen der Einzelleitungen durch Eindrücken der Einzelleitungen in die Schneidzonen der Einlegeschlitze mittels der Stempelblätter seitlich abgeschnitten werden.The process for forming cable sheaths is very easy with the help of the forming tool for field use. First, the individual lines are inserted into the insertion slots of the receiving element, and the lever arm is pivoted in until the stamp sheets rest on the individual lines. The actuating element is then swiveled in using the handle. In the following, pressure is exerted on the lever arm and the stamp sheets with the aid of the handle, so that the line sheaths of the individual lines are cut off laterally by pressing the individual lines into the cutting zones of the insertion slots by means of the stamp sheets.

Das Umformwerkzeug nach Figur 1 enthält ein Basisgestell 1, ein Aufnahmeelement 4 für eine oder mehrere umzuformende HF- Einzelleitungen, ein Eindrückelement 7 und ein auf das Eindrückelement einwirkendes Betätigungselement 9, welches mit Hilfe eines Handgriffes 3 verschiebbar ist. Am Eindrückelement 7 sind Stempelblätter 8 zu erkennen, welche genau auf Eindrückschlitze 5 des Aufnahmeelementes 4 ausgerichtet sind.The forming tool according to FIG. 1 contains a base frame 1, a receiving element 4 for one or more HF individual lines to be formed, a pressing element 7 and an actuating element 9 acting on the pressing element, which can be moved with the aid of a handle 3. On the press-in element 7, stamp sheets 8 can be seen, which are precisely aligned with press-in slots 5 of the receiving element 4.
BERICHTIGTES BLATT (REGEL 91) ISA/EP Das Eindrückelement 7 ist an einem Hebelarm 2 befestigt, welcher mit einem Ende am Basisgestell 1 gelagert ist (Figur 2) . Das Eindrückelement 7 ist am freien Ende des Hebelarms 2 angebracht und ist bei Betätigung des Hebelarmes 2 auf einer kreisförmigen Bahn geführt. Das mit dem Eindrückelement 7 zusammenwirkende Aufnahmeelement 4 ist am Basisgestell 1 montiert. Ferner ist anhand von Figur 2 zu erkennen, daß der Hebelarm 2 mit einem Höhenanschlag 10 ausgestattet ist.CORRECTED SHEET (RULE 91) ISA / EP The push-in element 7 is fastened to a lever arm 2 which is supported at one end on the base frame 1 (FIG. 2). The push-in element 7 is attached to the free end of the lever arm 2 and is guided on a circular path when the lever arm 2 is actuated. The receiving element 4 cooperating with the pressing element 7 is mounted on the base frame 1. It can also be seen from FIG. 2 that the lever arm 2 is equipped with a height stop 10.
Anhand von Figur 3 sind die Details des Aufnahmeelementes 4 und des Eindrückelementes 7 näher dargestellt. Die am Eindrückelement 7 angeformten Stempelblätter 8 sind an ihrer dem Aufnahmeelement 4 zugewandten Kante konkav ausgebildet, so daß die Stempelblätter 8 an die Kontur einzupressender Einzelleitungen 11 im Sinne einer verbesserten Führung angepaßt sind. Die Einlegeschlitze 5 am Aufnahmeelement 4 sind von innen nach außen verbreitert ausgeführt, so daß die Einzelleitungen 11 zunächst in die verbreiterten Außenbereiche der Einlegeschlitze 5 eingelegt werden können und bündig mit der Außenkontur des Auf ahmeelementes 4 abschließen. Dies dient ebenfalls einer verbesserten Führung der Einzelleitungen 11 beim Einpreßvorgang, wodurch ein Verschieben der Einzelleitungen 11 verhindert und ihrer Beschädigung vorgebeugt wird. An den Trennstellen zwischen den beiden unterschiedlich breiten Abschnitten der Einlegeschlitze 5 sind Schneidzonen 6 ausgebildet, welche das Material der Leitungsummantelungen 12a (siehe dazu Figur 4A) seitlich abtragen.The details of the receiving element 4 and the pressing element 7 are shown in more detail with reference to FIG. 3. The stamp sheets 8 formed on the pressing-in element 7 are concave on their edge facing the receiving element 4, so that the stamp sheets 8 are adapted to the contour of individual lines 11 to be pressed in in the sense of improved guidance. The insertion slots 5 on the receiving element 4 are widened from the inside out, so that the individual lines 11 can first be inserted into the widened outer regions of the insertion slots 5 and are flush with the outer contour of the receiving element 4. This also serves to improve the guidance of the individual lines 11 during the press-in process, as a result of which the individual lines 11 are prevented from moving and their damage is prevented. At the separation points between the two differently wide sections of the insertion slots 5, cutting zones 6 are formed which laterally remove the material of the cable sheaths 12a (see FIG. 4A).
Die Figuren 4A bis 4C veranschaulichen die Querschnittsverhältnisse bei einer HF-Einzelleitung 11a in ursprünglichem Zustand (Figur 4A) , bei einer HF-Einzelleitung 11b in umgeformtem Zustand (Figur 4B) und bei einer NF-Einzelleitung 11c (Figur 4C) . Für das Anschlagen von NF- und HF-Einzelleitungen an einen gemeinsamen IDC-Steckverbinder erweisen sich die stark unterschiedlichen Kabeldurchmesser als nachteilig, wo-FIGS. 4A to 4C illustrate the cross-sectional relationships in the case of an HF individual line 11a in the original state (FIG. 4A), in the case of an HF individual line 11b in the deformed state (FIG. 4B) and in the case of an LF individual line 11c (FIG. 4C). For the attachment of LF and HF individual lines to a common IDC connector, the widely differing cable diameters have proven to be disadvantageous.

Remedied by lateral Abschnei ¬ of the cable sheath 12a, wherein the sheathing development of the formed single RF line 11b is optimized such that it is matched in its width to the diameter of NF-single line 11c. As a result, HF individual lines 11b and LF individual lines 11c can be attached to a common IDC connector without any problems.
Der Umformvorgang selbst wird im folgenden anhand der Figuren 1 bis 3 näher erläutert.The forming process itself is explained in more detail below with reference to FIGS. 1 to 3.
Zunächst wird die Vorrichtung durch Einlegen der Einzelleitungen 11 in die Einlegeschlitze 5 des Aufnahmeelementes 4 bestückt. Im folgenden wird der Hebelarm 2 so weit einge- schwenkt, bis die Stempelblätter 8 mit ihren konkav ausgeformten Außenkanten an den in den äußeren Abschnitten der Einlegeschlitze 5 fixierten Einzelleitungen 11 aufliegen. Danach wird das Betätigungselement 9 mit Hilfe des Handgriffs 3 weiter eingeschwenkt, so daß direkt Druck auf den Hebelarm 2 und die Stempelblätter 8 ausgeübt wird. Unter weiterem Eindrücken der Einzelleitungen 11 in die Einlegeschlitze 5 werden die Leitungsummantelungen der Einzelleitungen 11 an den Schneidzonen 6 abgetrennt .First, the device is fitted by inserting the individual lines 11 into the insertion slots 5 of the receiving element 4. In the following, the lever arm 2 is pivoted in until the stamp sheets 8 with their concavely shaped outer edges rest on the individual lines 11 fixed in the outer sections of the insertion slots 5. Then the actuating element 9 is pivoted further by means of the handle 3, so that pressure is exerted directly on the lever arm 2 and the stamp sheets 8. With further pressing of the individual lines 11 into the insertion slots 5, the line sheaths of the individual lines 11 are cut off at the cutting zones 6.
Die so umgeformten HF-Einzelleitungen können in einem nächsten Arbeitsschritt zusammen mit NF-Einzelleitungen an einem gemeinsamen IDC-Steckverbinder angeschlagen werden. The RF individual lines thus formed can be attached to a common IDC connector in a next step together with NF individual lines.
