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 connection element for electrical lines, that in a cross-sectionally U-shaped connection area for line with at least one pair of each other opposite crimp legs is formed.

Derartige Anschlußorgane sind durch DE 89 09 562 U1 und DE 93 04 392 U1 bekannt, wo sie das Anschlußteil eines Kontaktelementes mit Schneidklemm- und Crimpanschluß bilden.Such connection members are by DE 89 09 562 U1 and DE 93 04 392 U1 known where it is the connecting part of a contact element Form 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 known connection elements, the connection area for an insulated electrical line is designed with a pair or more pairs of crimp legs and is generally designed for lines of a single specific diameter. If several such similar connection elements as part of a contact z. B. used in a contact housing of an electrical connector and lines of different diameters to be connected, they must be attached to the connection elements with processing tools specially matched to the respective line diameter. A practical example is a multi-pole contact housing that is fully equipped with contacts, in which cables with a cable cross-section of, for example, 0.35 and 0.5 mm 2 are processed. In a first step, for example, the lines of smaller cross-section must be struck sequentially with a special tool on the contacts provided. In a second step, the cables of the larger cross section must be struck sequentially on the remaining contacts using a special tool. This results in a processing 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 a simple and cheaper solution for crimp connection of different Specify cable diameters.

Diese Aufgabe wird bei einem Anschlußorgan der eingangs genannten Art gemaß 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 task is carried out at a connecting member of the aforementioned Art solved according to the invention in that from the Wall of each crimp leg at least one retaining tab so ripped out and inward towards the opposite Leg is bent that two opposite each other Holding flaps of a pair of crimp legs with theirs free end are directed 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 connector, the crimp legs are also Provide holding tabs for the electrical line. The holding tabs are torn out of the wall of a crimp leg and bent inwards. Tearing out the retaining tabs is in connection organs, which - especially if they Connection part of a contact element for electrical plug connections form - usually manufactured in a stamping and bending process are made possible by this in the wall corresponding separating cuts are introduced into the crimping leg become. To hold flaps with their free ends on top of each other To get straightened are in the crimp legs thus two mutually parallel, spaced apart Separation cuts perpendicular to the longitudinal direction and one in the longitudinal direction the line across the two parallel cuts Make another separating cut.

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 the torn out of the wall of the crimp legs, after inside bent state are two related lobes spaced from the bottom of the connection area, that is they protrude freely into the interior between two crimp legs. The retaining tabs thus form a support for one Electrical crimp connection to be inserted between two crimp legs Management. Generally the electrical lines insulated electrical cables for a crimp connection, however, it is also conceivable to use bare electrical conductors on one Fasten 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 Leitungsquerscnnitt 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 design of a connection element is now suitable in the following manner for lines with different cross-sections. 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 the cables with a smaller cross-section are attached, the insulated cable rests on the retaining tab after the crimp legs have been rolled over the cable insulation. These penetrate somewhat into the isolation. When the cables of larger cross section are struck, the insulated cable pushes the retaining tabs down, that is, back into the wall of the crimp legs, 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 crimp connection formed by the retaining tabs, which is so designed that no plunger stroke adjustment on the processing tool is required when connecting lines with different cross sections.

Die erfindungsgemäße Ausbildung eines Anschlußorganes hat somit die Vorteile, daß bei der Verarbeitung von Leitungen unterschiedlichen Querschnitts mindestens ein Verarbeitungswerkzeug eingespart wird und die Möglichkeit der parallelen Verarbeitung aller Kontakte gegeben ist (Zeitersparnis).The formation of a connecting element according to the invention thus has the advantages that different when processing lines Cross-section at least one processing tool is saved and the possibility of parallel Processing of all contacts is given (time saving).

Durch eine speziell abgestimmte Länge der Haltelappen werden für die unterschiedlichen Leitungsquerschnitte jeweils optimale Haltekräfte erreicht.Thanks to a specially matched length of the retaining tabs optimal for the different line cross-sections Holding forces reached.

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 area 2 and one Connection area 3 as the connection element according to the invention. The contact area 2 can be, for example, from a contact socket or a contact spring into which a contact pin is formed or a contact knife of a counter contact element can be inserted. The connection area 3 is for connection of the contact element 1 with an insulated electrical Ladder is provided and has an essentially U-shaped cross section on, creating a channel for insertion an end section of a not shown in Figure 1 electrical conductor is formed. For one Insulation displacement connection of the conductor are from the bottom 13 of the Connection area 3 cut out floor panels 4, 5 and transverse to the longitudinal direction of the connection area 3 between side walls 6, 7 of the U-shape angled perpendicular to the floor 13, so that the bottom wall parts 4, 5 run parallel to each other, are spaced from each other and one by two opposing blades 8 formed slot 9 form for the introduction of the insulated conductor. To this The way is the contact element shown in Figures 1 and 2 1 with two each formed by the bottom wall parts 4 and 5 Provide 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 area 2 Side of the insulation displacement point 4 is an outer pair of crimp legs 10, 11 provided in the side walls 6, 7 of the connection area 3 are formed and lie opposite one another. The crimp legs 10, 11 of the outer pair are Shark fin-like and opposed to each other staggered. Furthermore, the connection area 3 to Crimp connection of the conductor on its two long sides still with another pair of opposite, identically shaped crimp legs 12, 13 provided, which also formed in the side walls 6, 7 of the connection area 3 and in the same way as the crimp legs 10, 11 of the outer pair of crimp legs offset in opposite directions, but as an inner pair of crimp legs between the Insulation displacement points 4 and 5 are arranged. With that point all four crimp legs 10 to 13 have the same shape and the same Height up, the height of the crimp legs before bending or curling 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 due to higher pull-out forces and its compact design for contact arrangements with very small pitch suitable. Striking the line, the is called pressing the conductor into the insulation displacement points 4, 5, and the bending or curling of the crimp legs 10 up 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 implement a crimp connection for lines of different cross-sections (for example 0.35 and 0.5 mm 2 ) with one and the same embodiment of a connecting element, the crimp legs 10 to 13 are designed with retaining tabs 14 to 17 in the following manner. From the wall of each crimp leg - after the introduction of two mutually parallel, spaced-apart and perpendicular to the direction of the line separating cuts and a longitudinal cross-cut when producing the contact element in a stamping and bending process - here a narrow retaining tab 14, 15 and 16 respectively , 17 torn out and bent inwards towards the opposite crimp leg in such a way that two opposing retaining tabs 14, 15 and 16, 17 of a pair of crimp legs 10, 11 and 12, 13 are directed towards each other with their free end 21. The retaining tabs 14, 15 and 16, 17 are each provided at mutually opposite positions of the crimp legs 10 to 13, so that they are aligned with one another in the inwardly bent state (FIG. 1). In the state torn out of the wall of the crimp legs 10 to 13, that is to say in the initial state before the crimp connection, the retaining tabs 14 to 17 run parallel and spaced apart from the base 20 of the connection region 3 (FIG. 3). The length of the retaining tabs 14 to 17 is specially matched to the cable diameter, i.e. to a cable outer diameter over the insulation of approx. 1.3 - 1.4 mm for the cable with a smaller cross-section and approx. 1.6 mm for the cable 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. Figures 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 line diameter of approximately 1.3-1.4 mm) lies on the retaining tabs 12 and 13 after the insulation displacement connection and the rolling in of the crimp legs 16, 17, which easily penetrate the cable insulation. The line 19 (for example with a cross section of 0.5 mm 2 and a line diameter of approximately 1.6 mm) pushes the retaining tabs 16, 17 down and into the wall of the crimp legs, so that in the final state (FIG. 5 ) rests on the floor 20 of the connection area 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 version of a crimp connection is suitable for lines with different cross sections. As shown in FIGS. 4 and 5, in both cases the crimp connection of the lines without punch stroke adjustment on the processing tool ( X1 = X2 ) possible. In addition, optimal holding forces are achieved for both line cross sections.
