Description

Die Erfindung betrifft ein Anschlußorgan für elektrische Leitungen, das in einem im Querschnitt U-förmigen Anschlußbereich für die Leitung mit mindestens einem Paar von einander gegenüberliegenden Crimpschenkeln ausgebildet ist.The invention relates to a connecting element for electrical lines, which is formed in a cross-sectionally U-shaped connection region for the line with at least one pair of opposing crimp legs.

Derartige Anschlußorgane sind durch DE 89 09 562 U1, JP9-180772 und DE 93 04 392 U1 bekannt, wo sie das Anschlußteil eines Kontaktelementes mit Schneidklemm- und Crimpanschluß bilden.Such connecting members are known from DE 89 09 562 U1, JP9-180772 and DE 93 04 392 U1, where they form the terminal part of a contact element with insulation displacement and crimp connection.

Bei den bekannten Anschlußorganen ist der Anschlußbereich für eine isolierte elektrische Leitung mit einem Paar oder mehreren Paaren von Crimpschenkeln ausgebildet und im allgemeinen für Leitungen eines einzigen bestimmten Durchmessers ausgelegt. Wenn mehrere solche gleichartige Anschlußorgane als Bestandteil eines Kontaktes z. B. in einem Kontaktgehäuse eines elektrischen Steckverbinders verwendet und Leitungen unterschiedlichen Durchmessers angeschlossen werden sollen, so müssen diese mit speziell auf den jeweiligen Leitungsdurchmesser abgestimmten Verarbeitungswerkzeugen an den Anschlußorganen angeschlagen werden. Als Beispiel aus der Praxis sei ein vielpoliges, mit Kontakten vollbestücktes Kontaktgehäuse betrachtet, bei dem Leitungen mit einem Leitungsquerschnitt von zum Beispiel 0,35 und 0,5 mm2 verarbeitet werden. Hierbei müssen in einem ersten Arbeitsschritt zum Beispiel die Leitungen des kleineren Querschnitts sequentiell mit einem speziellen Werkzeug an die dafür vorgesehenen Kontakte angeschlagen werden. In einem zweiten Arbeitsschritt müssen wiederum mit einem speziellen Werkzeug die Leitungen des größeren Querschnitts sequentiell an die verbleibenden Kontakte angeschlagen werden. Dies hat eine verarbeitungsmittel- und zeitaufwendige Vorgehensweise zur Folge.In the prior art connection members, the insulated electrical lead terminal region is formed with a pair or more pairs of crimp legs and is generally designed for single single diameter leads. If several such similar connection organs as part of a contact z. B. used in a contact housing of an electrical connector and cables of different diameters to be connected, they must be posted with specially tailored to the respective pipe diameter processing tools to the terminal organs. As an example from the practice, a multi-pole, fully equipped with contacts contact housing is considered, are processed in the lines with a cross-section of, for example, 0.35 and 0.5 mm 2 . Here, in a first step, for example, the lines of the smaller cross-section must be sequentially struck with a special tool to the designated contacts. In a second step, in turn, the lines of the larger cross section must be sequentially connected to the remaining contacts with a special tool. This results in a processing-consuming and time-consuming procedure.

Der Erfindung liegt die Aufgabe zugrunde, eine einfache und kostengünstigere Lösung zum Crimpanschluß von unterschiedlichen Leitungsdurchmessern anzugeben.The invention has for its object to provide a simple and cost-effective solution for crimping of different cable diameters.

Diese Aufgabe wird bei einem Anschlußorgan der eingangs genannten Art gemäß der Erfindung dadurch gelöst, daß aus der Wandung eines jeden Crimpschenkels mindestens ein Haltelappen so herausgerissen und nach innen in Richtung auf den gegenüberliegenden Schenkel gebogen ist, daß zwei einander gegenüberliegende Haltelappen eines Crimpschenkelpaares mit ihrem freien Ende aufeinander zu gerichtet sind.This object is achieved in a connecting member of the type mentioned according to the invention in that out of the wall of each crimp leg at least one retaining tabs is torn out and bent inwardly toward the opposite leg that two opposing retaining tabs of a pair of crimp legs with their free Towards each other.

Bei einem derartigen Anschlußorgan sind die Crimpschenkel mit Haltelappen für die elektrische Leitung versehen. Die Haltelappen sind aus der Wandung eines Crimpschenkels herausgerissen und nach innen gebogen. Das Herausreißen der Haltelappen wird bei Anschlußorganen, die - insbesondere, wenn sie das Anschlußteil eines Kontaktelementes für elektrische Steckverbindungen bilden - meist in einem Stanzbiegeverfahren hergestellt werden, dadurch ermöglicht, daß hierbei in die Wandung der Crimpschenkel entsprechende Trennschnitte eingebracht werden. Um Haltelappen, die mit ihrem freien Ende aufeinander zu gerichtet sind, zu erhalten, sind in den Crimpschenkeln also zwei zueinander parallele, voneinander beabstandete Trennschnitte senkrecht zur Längsrichtung und ein in Längsrichtung der Leitung quer zu den beiden parallelen Trennschnitten verlaufender weiterer Trennschnitt anzubringen.In such a connecting member, the crimp legs are provided with retaining tabs for electrical conduction. The retaining tabs are torn out of the wall of a crimp leg and bent inwards. The tearing out of the retaining tabs is in connection organs, which - in particular, if they form the connection part of a contact element for electrical connections - are usually made in a stamping bending process, thereby allowing this in the wall of the crimp leg corresponding separating cuts are introduced. In order to obtain retaining tabs which are directed towards one another with their free end, two mutually parallel, mutually spaced separating cuts perpendicular to the longitudinal direction and one in the longitudinal direction of the line transverse to the two parallel separating cuts extending further separating cut are to be attached in the crimp legs.

Im aus der Wandung der Crimpschenkel herausgerissenen, nach innen gebogenen Zustand sind zwei zusammengehörende Haltelappen vom Boden des Anschlußbereiches beabstandet, das heißt sie ragen frei in den Innenraum zwischen zwei Crimpschenkeln. Die Haltelappen bilden somit also eine Auflage für eine zum Crimpanschluß zwischen zwei Crimpschenkeln einzufügende elektrische Leitung. Im allgemeinen sind die elektrischen Leitungen bei einem Crimpanschluß isolierte elektrische Leitungen, es ist jedoch auch denkbar, blanke elektrische Leiter an einem Crimpanschluß zu befestigen.In torn from the wall of the crimp leg, inwardly bent state two matching retaining tabs are spaced from the bottom of the terminal area, that is, they protrude freely in the interior space between two crimp legs. The retaining tabs thus thus form a support for an electrical line to be inserted for crimping between two crimp legs. In general, the electrical leads in a crimp connection are insulated electrical leads, However, it is also conceivable to attach bare electrical conductors to a crimp connection.

Die erfindungsgemäße Ausbildung eines Anschlußorganes ist nun in folgender Weise für Leitungen mit unterschiedlichem Querschnitt geeignet. Als Beispiel werden isolierte elektrische Leitungen mit einem Leitungsquerschnitt von 0,35 mm2 (Außendurchmesser über die Isolation ca. 1,3 - 1,4 mm) und mit einem Leitungsquerschnitt von 0,5 mm2 (Außendurchmesser über die Isolation ca. 1,6 mm) angenommen. Beim Anschlagen der Leitungen kleineren Querschnitts liegt die isolierte Leitung nach dem Einrollen der Crimpschenkel über die Leitungsisolation auf den Haltelappen auf. Diese dringen hierbei etwas in die Isolation ein. Beim Anschlagen der Leitungen größeren Querschnitts drängt die isolierte Leitung die Haltelappen nach unten, also zurück in die Wandung der Crimpschenkel, und liegt dann auf dem Boden des Anschlußbereiches auf. Die Besonderheit der Erfindung ist also in der durch die Haltelappen gebildeten Geometrie des Crimpanschlusses zu sehen, der damit so ausgebildet ist, daß beim Anschlagen von Leitungen mit unterschiedlichen Querschnitten keine Stempelhubverstellung am Verarbeitungswerkzeug erforderlich wird.The inventive construction of a connecting element is now suitable in the following manner for cables with different cross section. As an example, insulated electrical cables with a cable cross section of 0.35 mm 2 (outer diameter over the insulation approx. 1.3 - 1.4 mm) and with a cable cross section of 0.5 mm 2 (outer diameter over the insulation approx. 1, 6 mm). When hitting the lines of smaller cross section, the insulated line is after rolling the crimp leg on the line insulation on the retaining tabs. These penetrate something in the isolation. When hitting the lines of larger cross-section, the insulated line pushes the retaining tabs down, ie back into the wall of the crimp leg, and then lies on the bottom of the connection area. The peculiarity of the invention is thus to be seen in the geometry of the crimping connection formed by the retaining tabs, which is thus designed so that no punch stroke adjustment on the processing tool is required when striking lines with different cross sections.

Die erfindungsgemäße Ausbildung eines Anschlußorganes hat somit die Vorteile, daß bei der Verarbeitung von Leitungen unterschiedlichen Querschnitts mindestens ein Verärbeitungswerkzeug eingespart wird und die Möglichkeit der parallelen Verarbeitung aller Kontakte gegeben ist (Zeitersparnis).The inventive design of a connecting member thus has the advantages that at least one processing tool is saved in the processing of lines of different cross-section and the possibility of parallel processing of all contacts is given (time savings).

Durch eine speziell abgestimmte Länge der Haltelappen werden für die unterschiedlichen Leitungsquerschnitte jeweils optimale Haltekräfte erreicht.By a specially tuned length of the retaining tabs optimum holding forces are achieved for the different cable cross sections.

Das Kontaktelement 1 weist einen Kontaktbereich 2 und einen Anschlußbereich 3 als das erfindungsgemäße Anschlußorgan auf. Der Kontaktbereich 2 kann zum Beispiel von einer Kontaktbuchse oder einer Kontaktfeder gebildet sein, in die ein Kontaktstift oder ein Kontaktmesser eines Gegenkontaktelementes eingesteckt werden kann. Der Anschlußbereich 3 ist zur Verbindung des Kontaktelementes 1 mit einem isolierten elektrischen Leiter vorgesehen und weist hierzu einen im wesentlichen U-förmigen Querschnitt auf, wodurch ein Kanal zum Einlegen eines Endabschnittes eines in Figur 1 nicht näher dargestellten elektrischen Leiters gebildet wird. Für einen Schneidklemmanschluß des Leiters sind aus dem Boden 13 des Anschlußbereiches 3 Bodenwandteile 4, 5 freigeschnitten und quer zur Längsrichtung des Anschlußbereiches 3 zwischen Seitenwände 6, 7 der U-Form senkrecht zum Boden 13 abgewinkelt, so daß die Bodenwandteile 4, 5 zueinander parallel verlaufen, voneinander beabstandet sind und jeweils einen durch zwei einander gegenüberliegende Schneiden 8 gebildeten Schlitz 9 für die Einführung des isolierten Leiters bilden. Auf diese Weise ist das in den Figuren 1 und 2 dargestellte Kontaktelement 1 mit jeweils zwei von den Bodenwandteilen 4 und 5 gebildeten Schneidklemmstellen versehen.The contact element 1 has a contact region 2 and a connection region 3 as the connection element according to the invention. The contact region 2 can be formed for example by a contact socket or a contact spring into which a contact pin or a contact blade of a mating contact element can be inserted. The connection region 3 is provided for connection of the contact element 1 with an insulated electrical conductor and for this purpose has a substantially U-shaped cross-section, whereby a channel for inserting an end portion of an electrical conductor not shown in detail in Figure 1 is formed. For an insulation displacement connection of the conductor 3 bottom wall parts 4, 5 are cut free and angled transversely to the longitudinal direction of the connection region 3 between side walls 6, 7 of the U-shape perpendicular to the bottom 13 so that the bottom wall parts 4, 5 extend parallel to each other are spaced apart and one each through two Forming opposite edges 8 formed slot 9 for the introduction of the insulated conductor. In this way, the contact element 1 shown in Figures 1 and 2 is provided with two each of the bottom wall parts 4 and 5 formed insulation displacement points.

Zum Crimpanschluß des Leiters an der dem Kontaktbereich 2 abgewandten Seite der Schneidklemmstelle 4 ist ein äußeres Paar von Crimpschenkeln 10, 11 vorgesehen, die in den Seitenwänden 6, 7 des Anschlußbereiches 3 ausgeformt sind und sich gegenüberliegen. Die Crimpschenkel 10, 11 des äußeren Paares sind haifischflossenartig gestaltet und zueinander gegensinnig versetzt angeordnet. Ferner ist der Anschlußbereich 3 zum Crimpanschluß des Leiters an seinen beiden Längsseiten noch mit einem weiteren Paar von einander gegenüberliegenden, gleich geformten Crimpschenkeln 12, 13 versehen, die ebenfalls in den Seitenwänden 6, 7 des Anschlußbereiches 3 ausgeformt und in gleicher Weise wie die Crimpschenkel 10, 11 des äußeren Crimpschenkelpaares gegensinnig gegeneinander versetzt, aber als inneres Crimpschenkelpaar zwischen den Schneidklemmstellen 4 und 5 angeordnet sind. Damit weisen alle vier Crimpschenkel 10 bis 13 die gleiche Form und gleiche Höhe auf, wobei die Höhe der Crimpschenkel vor dem Umbiegen oder Einrollen etwa gleich der Höhe der Seitenwände 6, 7 und der Schneidklemmstellen 4, 5 des Anschlußbereiches 3 ist. Das Kontaktelement ist für höhere Ausreißkräfte und aufgrund seines kompakten Aufbaus für Kontaktanordnungen mit sehr kleinem Rastermaß geeignet. Das Anschlagen der Leitung, das heißt das Eindrücken des Leiters in die Schneidklemmstellen 4, 5, und das Umbiegen oder Einrollen der Crimpschenkel 10 bis 13 kann in einem Werkzeug und in einem Arbeitsgang erfolgen.For crimping the conductor on the side facing away from the contact region 2 of the insulation displacement point 4, an outer pair of crimp legs 10, 11 are provided, which are formed in the side walls 6, 7 of the connection region 3 and opposite each other. The crimp legs 10, 11 of the outer pair are shark fin shaped and arranged offset in opposite directions. Further, the terminal portion 3 is provided to the crimp terminal of the conductor at its two longitudinal sides with another pair of opposed, equally shaped crimp legs 12, 13, which are also formed in the side walls 6, 7 of the terminal portion 3 and in the same manner as the crimp leg 10th , 11 of the outer crimp leg pair offset in opposite directions to each other, but are arranged as an inner crimp leg pair between the insulation displacement points 4 and 5. Thus, all four crimp legs 10 to 13 have the same shape and height, wherein the height of the crimp leg before bending or curling is approximately equal to the height of the side walls 6, 7 and the insulation displacement points 4, 5 of the connection area 3. The contact element is suitable for higher pull-out forces and because of its compact design for contact arrangements with a very small pitch. The striking of the line, that is, the pressing of the conductor in the insulation displacement points 4, 5, and the bending or curling of the crimp legs 10 to 13 can be done in one tool and in one operation.

Um nun mit ein und derselben Ausführungsform eines Anschlußorganes einen Crimpanschluß für Leitungen unterschiedlichen Querschnitts (zum Beispiel 0,35 und 0,5 mm2) realisieren zu können, sind die Crimpschenkel 10 bis 13 in folgender Weise mit Haltelappen 14 bis 17 ausgebildet. Aus der Wandung eines jeden Crimpschenkels ist - nach der Einbringung von zwei zueinander parallelen, voneinander beabstandeten und senkrecht zur Leitungsrichtung verlaufenden Trennschnitten und einem in Längsrichtung verlaufenden Quertrennschnitt bei der Herstellung des Kontaktelementes in einem Stanzbiegeverfahren - hier jeweils ein schmaler Haltelappen 14, 15 bzw. 16, 17 so herausgerissen und nach innen in Richtung auf den gegenüberliegenden Crimpschenkel gebogen, daß zwei einander gegenüberliegende Haltelappen 14, 15 bzw. 16, 17 eines Crimpschenkelpaares 10, 11 bzw. 12, 13 mit ihrem freien Ende 21 aufeinander zu gerichtet sind. Die Haltelappen 14, 15 bzw. 16, 17 sind jeweils an einander gegenüberliegenden Stellen der Crimpschenkel 10 bis 13 vorgesehen, so daß sie im nach innen gebogenen Zustand zueinander fluchten (Figur 1). Im aus der Wandung der Crimpschenkel 10 bis 13 herausgerissenen Zustand, also im Ausgangszustand vor dem Crimpanschluß, verlaufen die Haltelappen 14 bis 17 parallel und beabstandet zum Boden 20 des Anschlußbereiches 3 (Figur 3). Die Länge der Haltelappen 14 bis 17 ist speziell auf den Leitungsdurchmesser abgestimmt, also auf einen Leitungs-Außendurchmesser über die Isolation von ca. 1,3 - 1,4 mm bei der Leitung kleineren Querschnitts und von ca. 1,6 mm bei der Leitung größeren Querschnitts.In order to be able to realize a crimp connection for lines of different cross-section (for example 0.35 and 0.5 mm 2 ) with one and the same embodiment of a connection element, the crimp legs 10 to 13 are in the following manner formed with retaining tabs 14 to 17. From the wall of each crimp leg is - after the introduction of two mutually parallel, spaced apart and perpendicular to the line direction separating cuts and a longitudinal cross-cutting in the manufacture of the contact element in a stamping process - here in each case a narrow retaining tabs 14, 15 and 16 , 17 so torn and bent inwardly towards the opposite crimp leg that two opposing retaining tabs 14, 15 and 16, 17 of a crimp leg pair 10, 11 and 12, 13 are directed with their free end 21 toward each other. The retaining tabs 14, 15 and 16, 17 are respectively provided at opposite points of the crimp legs 10 to 13, so that they are aligned in the inwardly bent state to each other (Figure 1). In the torn from the wall of the crimp leg 10 to 13 state, ie in the initial state before the crimp, the retaining lugs 14 to 17 parallel and spaced from the bottom 20 of the connection area 3 (Figure 3). The length of the holding lugs 14 to 17 is specially adapted to the line diameter, ie to a line outer diameter over the insulation of about 1.3 - 1.4 mm in the line of smaller cross-section and of about 1.6 mm in the line larger cross section.

Die Figuren 4 und 5 zeigen nun den vollzogenen Crimpanschluß der beiden unterschiedlichen Leitungen. Die Leitung 18 (zum Beispiel mit einem Querschnitt von 0,35 mm2 und einem Leitungsdurchmesser von ca. 1,3 - 1,4 mm) liegt nach dem Schneidklemmanschluß und dem Einrollen der Crimpschenkel 16, 17 auf den Haltelappen 12 und 13 auf, welche leicht in die Leitungsisolation eindringen. Die Leitung 19 (zum Beispiel mit einem Querschnitt von 0,5 mm2 und einem Leitungsdurchmesser von ca. 1,6 mm) drängt die Haltelappen 16, 17 nach unten und in die Wandung der Crimpschenkel zurück, so daß sie im Endzustand (Figur 5) auf dem Boden 20 des Anschlußbereiches 3 aufliegt.FIGS. 4 and 5 now show the completed crimp connection of the two different lines. The line 18 (for example, with a cross section of 0.35 mm 2 and a cable diameter of about 1.3 - 1.4 mm) is after the insulation displacement connection and the curling of the crimp legs 16, 17 on the retaining tabs 12 and 13, which easily penetrate the line insulation. The line 19 (for example, with a cross section of 0.5 mm 2 and a cable diameter of about 1.6 mm) urges the retaining tabs 16, 17 down and into the wall of the crimp leg, so that in the final state (Figure 5 ) rests on the bottom 20 of the connection region 3.

Auf diese Weise ist ein und dieselbe Ausführung eines Crimpanschlusses für Leitungen mit unterschiedlichem Querschnitt geeignet. Wie die Figuren 4 und 5 zeigen, ist in beiden Fällen der Crimpanschluß der Leitungen ohne Stempelhubverstellung am Verarbeitungswerkzeug (X1 = X2) möglich. Außerdem werden für beide Leitungsquerschnitte optimale Haltekräfte erreicht.In this way, one and the same embodiment of a crimp connection is suitable for cables with different cross sections. As shown in Figures 4 and 5, in both cases, the crimping of the lines without Stempelhubverstellung the processing tool (X1 = X2) is possible. In addition, optimum holding forces are achieved for both cable cross sections.
