Abstract

The flat cable connector comprises cutting-type terminal contacts (14, 16) with two pointed arms (18) which have a slot between them. The arms are crimped into the insulation (30) of a flat cable (24) and are mechanically secured in the latter. In this way they contact with the metallic conductor (26, 28) and thus make electrical contact with it. The flat cable can thus be joined with other cables or a printed circuit. According to the invention, the mechanical securing of the arm which is crimped into the insulation can be increased. For this purpose a projection (12) is provided on the cutting-type terminal, and extending from this projection is a fan-shaped element (22). Whereas the arms are crimped into the insulator of the flat cable from below, the fan-shaped element is pressed on to the cable from above. In this way, it is clamped between the arms and the fan-shaped element. This results in a mechanical connection between the cutting-type terminal and the flat cable which does not come loose even in the event of vibrations.

Description

FlachkabelverbinderFlat cable connector
Die Erfindung betrifft einen Flachkabelverbinder zürn An¬ schließen der Leiter eines Flachkabels an eine Leiterplatte oder zum Spleißen von zwei Flachkabeln 51it einem die Isola¬ tion durchstoßenden und zwischen sich einen Schlitz begren¬ zenden, U-Form aufweisenden Schneidklemmkontakt und mit ei¬ nem sich an diesen anschließenden Buchsenkontakt zum mecha¬ nischen und elektrischen Anschluß an einen mit einer Leiter¬ ik platte verbundenen Kontaktstift oder Kontaktstiftpaar oder mit einem identischen Schneidklemmkontakt zum mechanischen und elektrischen Anschluß an ein zweites Flachkabel. Schneid¬ klemmkontakte dieser Art sind bekannt. Sie weisen zwei ange¬ spitzte und angeschärfte Schenkel auf, die zwischen sich den Schlitz mit einer Breite von in etwa einer Leiterbreite be¬ grenzen. Zum Konfektionieren eines Flachkabels werden diese Schenkel in die Kabelisolation hineingedrückt. Dabei gelangen ihre Innenseiten mit dem Leiter in mechanische Berührung. Da¬ mit entsteht auch der gewünschte elektrische Kontakt. Mit diesem Schneidklemmkontakt sind paarweise Buchsenkontakte verbunden. Diese Buchsenkontakte stellen wiederum die Ver¬ bindung zu mechanisch und elektrisch mit der Leiterplatte verbundenen Kontaktstiften her. Damit entsteht auch hier ein gewünschter elektrischer Kontakt, und die Leiterbahn der Lei¬ terplatte wird elektrisch mit dem Leiter des Flachkabels ver¬ bunden. Ebenso gibt es Flachkabelverbinder, bei denen zwei Schneidklemmkontakte integral miteinander verbunden sind. Solche Flachkabelverbinder dienen zum Spleißen von Flach- kabeln.The invention relates to a flat cable connector for connecting the conductors of a flat cable to a printed circuit board or for splicing two flat cables 51 with an insulation displacement contact penetrating the insulation and defining a slot between them and having a U-shape and with an inherent connection this subsequent socket contact for mechanical and electrical connection to a contact pin or pair of contact pins connected to a circuit board or with an identical insulation displacement contact for mechanical and electrical connection to a second flat cable. Insulation displacement contacts of this type are known. They have two sharpened and sharpened legs which between them delimit the slot with a width of approximately one conductor width. To assemble a flat cable, these legs are pressed into the cable insulation. In doing so, their inner sides come into mechanical contact with the conductor. This also creates the desired electrical contact. Socket contacts are connected in pairs to this insulation displacement contact. These socket contacts in turn establish the connection to contact pins mechanically and electrically connected to the printed circuit board. Thus here a desired electrical contact, and the conductor track of Lei¬ arises terplatte is electrically connected to the conductor of the flat cable ver ¬. There are also flat cable connectors in which two insulation displacement contacts are integrally connected to one another. Such flat cable connectors are used for splicing flat cables.
Die erläuterte elektrische Verbindung hat nur dann Bestand, wenn der Flachkabelverbinder auch mechanisch fest mit dem oder den Flachkabeln verbunden bleibt. Bei den bekannten Flachkabelverbindern ergibt sich der mechanische Halt durch den Druck, mit dem der Leiter an den in die Isolation hinein¬ gedrückten Schneidklemmkontakten anliegt. Die sich daraus er¬ gebende Verklemmung reicht zum Halt aus, wenn die Flachkabel ortsfest verlegt sind und keine Bewegungen ausführen. Es gibt jedoch Anwendungen, bei denen die Flachkabelverbinder Vibra¬ tionen ausgesetzt sind. Hier kann sich die Verklemmung im Ex¬ tremfall lösen. Aufgabe der Erfindung ist damit eine solche Ausbildung eines Flachkabelverbinders, daß sein mechanischer Halt auf einem Flachkabel auch bei Vibrationen dauerhaft be¬ stehen bleibt. Die Lösung für diese Aufgabe ergibt sich bei einem Flachkabelverbinder der eingangs genannten Gattung durch einen unter einem rechten Winkel an den Schneidklemm¬ kontakt angeformten Steg und eine an diesen angeformte Fahne zum Aufdrücken auf einen Leiter des Flachkabels. Zusätzlich zu dem konventionellen Schneidklemmkontakt weist der Verbin¬ der somit eine Fahne auf, die nach dem Hineindrücken des Schneidklemmkontaktes in die Isolation auf den Leiter aufge¬ drückt wird. Dabei ergibt sich, daß der Schneidklemmkontakt von einer Seite, die unten genannt werden kann, in die Isola¬ tion hineingestoßen wird und die Fahne dann von oben auf den Leiter aufgedrückt wird. Damit umschließt der Flachkabelver¬ binder das Flachkabel und liegt von beiden Seiten an diesem an. Damit ergibt sich eine dauerhafte, sich auch bei Vibra¬ tionen nicht lösende Verbindung.The electrical connection explained only exists if the flat cable connector also remains mechanically firmly connected to the flat cable or cables. In the known flat cable connectors, the mechanical hold results from the pressure with which the conductor rests on the insulation displacement contacts pressed into the insulation. The resulting jamming is sufficient to hold when the flat cables are fixed in place and do not make any movements. However, there are applications in which the flat cable connectors are exposed to vibrations. Here the jamming can be released in extreme cases. The object of the invention is thus such a design of a flat cable connector that its mechanical hold on a flat cable remains even in the event of vibrations. The solution to this problem is obtained in the case of a flat cable connector of the type mentioned at the outset by a web formed at right angles on the insulation displacement contact and a tab integrally formed thereon for pressing onto a conductor of the flat cable. In addition to the conventional insulation displacement contact, the connector thus has a flag which is pressed onto the conductor after the insulation displacement contact has been pressed into the insulation. The result is that the insulation displacement contact is pushed into the insulation from one side, which can be mentioned below, and the flag is then pressed onto the conductor from above. The flat cable connector thus encloses the flat cable and lies against it from both sides. This results in a permanent connection that does not detach even with vibrations.
In einer zweckmäßigen Ausgestaltung ist an den Steg ein wei¬ terer Schneidklemmkontakt angeformt. Dabei können sich an je¬ dem Ende des Steges je zwei Schneidklemmkontakte paarweise gegenüberliegen. Dadurch wird die mechanische und elektri¬ sche Verbindung mi*- einem Kabel bzw. Jessen Leiter verstärkt. Ebenso können auch zwei Kabel miteinander verbunden werden.In an expedient embodiment, a further insulation displacement contact is molded onto the web. In this case, two insulation displacement contacts can lie opposite each other in pairs at each end of the web. This strengthens the mechanical and electrical connection mi * - a cable or Jessen conductor. Two cables can also be connected to each other.
In einer weiteren Ausgestaltung ist vorgesehen, daß je eine Fahne an jede Seite des Steges angeformt ist. Damit werden zwei miteinander zu verbindende Flachkabel vorsätzlich ge¬ halten.In a further embodiment it is provided that a flag is formed on each side of the web. Two flat cables to be connected to one another are thus intentionally held.
Der Steg und die beiden Schneidklemmkontakte weisen in der Aufsicht vorteilhaft die Form eines U auf.The web and the two insulation displacement contacts advantageously have the shape of a U when viewed from above.
Zum Verbinden von Flachkabeln mit unterschiedlicher Stärke ihrer Leiter sieht die Erfindung Schneidklemmkontakte mit unterschiedlicher Schlitzbreite vor.To connect flat cables with different thicknesses of their conductors, the invention provides insulation displacement contacts with different slot widths.

The flags 22 are bent again and rest on the coats 32 from above. To assemble the arrangement, the third housing part 42 with its clamps 44 is passed through the slots 40. The housing parts lock together. In this assembled state, the contact 46 and the contact pins 48 rest against the legs 18 assigned to them and make electrical contact with them. As a result, the conductors 26 and 28 are electrically connected to the conductor tracks (not shown) located on the printed circuit board 50. This electrical contact is maintained even with vibrations. The flags 22 bent up onto the flat cable prevent the leg 18 from being detached from the flat cable.
