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

Die Erfindung betrifft einen Flachkabelverbinder zum Anschließen der Leiter eines Flachkabels an eine Leiterplatte mit mindestens einem die Isolation durchstoßenden und zwischen sich einen Schlitz begrenzenden, U-Form aufweisenden Schneidklemmkontakt mit einem an diesen anlegbaren Buchsenkontakt und einem Kontaktstiftpaar zum mechanischen und elektrischen Anschluß an eine Leiterplatte mit einem unter einem rechten Winkel an den Schneidklemmkontakt angeformten Steg und mit einer an diesen angeformten Fahne zum Aufdrücken auf den Mantel des Flachkabels.The invention relates to a flat cable connector for connecting the conductors of a flat cable to a printed circuit board with at least one insulation-piercing insulation-piercing contact between a slot and having a U-shape and having an insertable socket contact and a pair of contact pins for mechanical and electrical connection to a printed circuit board a web molded onto the insulation displacement contact at a right angle and with a tab molded onto it for pressing onto the jacket of the flat cable.

Flachkabelverbinder zum Anschließen der Leiter eines Flachkabels mit einem die Isolation durchstoßenden und zwischen sich einen Schlitz begrenzenden, U-Form aufweisenden Schneidkontakt und mit einem sich an diesen anschließenden Buchsenkontakt zum mechanischen und elektrischen Anschluß an einen mit einer Platte verbundenen Kontaktstift oder Kontaktstiftpaar mit einem unter einem rechten Winkel an den Schneidklemmkontakt angeformten Steg und eine an diesen angeformte Fahne zum Aufdrücken auf den Mantel des Flachkabels sind bekannt (WO A-79/01118). Bekannt ist es auch, Schneidklemmkontakte der genannten Art mit den einzelnen Leitern des Flachkabels zu verbinden und diese Schneidklemmkontakte dann in einem getrennten Arbeitsgang in die Augen einer Leiterplatte einzusetzen und damit diese elektrisch mit den Leitern des Flachkabels zu verbinden (US-A 3 963 319). Bekannt ist auch ein Flachkabelverbinder, der mit die Isolation verdrängenden Schneidklemmkontakten an die einzelnen Leiter eines Flachkabels angeschlossen und mit einem an seinem anderen Ende vorgesehenen Schlitz über eine Leiterplatte geschoben wird. In dem zuletzt genannten Schlitz befinden sich Blattfedern, die sich federnd an die beiden Seiten der Leiterplatte anlegen und dabei gleichzeitig elektrischen Kontakt machen (GB-A-2 037 494).Flat cable connector for connecting the conductors of a flat cable with a cutting contact penetrating the insulation and defining a slot between them and having a U-shape and with an adjoining socket contact for mechanical and electrical connection to a contact pin connected to a plate or a pair of contact pins with one under one Right angles to the web formed on the insulation displacement contact and a tab formed thereon for pressing onto the jacket of the flat cable are known (WO A-79/01118). It is also known to connect insulation displacement contacts of the type mentioned to the individual conductors of the flat cable and then insert these insulation displacement contacts into the eyes of a printed circuit board in a separate operation and thus to electrically connect them to the conductors of the flat cable (US Pat. No. 3,963,319). . Also known is a flat cable connector which is connected to the insulation displacement displacement contacts to the individual conductors of a flat cable and is pushed over a circuit board with a slot provided at its other end. In the last-mentioned slot there are leaf springs which rest resiliently on the two sides of the circuit board and at the same time make electrical contact (GB-A-2 037 494).

Von diesem Stand der Technik ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Flachkabelverbinder so auszubilden, daß er mit wenigen Arbeitsschritten einfach sowohl mit den Leitern eines Flachkabels als auch mit einer Leiterplatte verbunden werden kann und damit diese beiden Teile elektrisch miteinander verbindet. Diese Verbindung soll stoß-und schwingungsfest sein. Die Lösung für diese Aufgabe ergibt sich bei einem Flachkabelverbinder der eingangs genannten Gattung nach der Erfindung dadurch, daß der Schneidklemmkontakt in einem Gehäuse aus einem Unterteil und einem Oberteil und der Buchsenkontakt und das Kontaktstiftpaar in einem dritten Gehäuseteil angeordnet sind, in dem Unterteil Öffnungen zum Durchführen des Buchsenkontaktes und des Kontaktstiftpaares zwecks Anlage an dem Schneidklemmkontakt vorgesehen sind und das Gehäuse seitlich Schlitze und das dritte Gehäuseteil durch diese durchsteckbare und mit ihnen verriegelbare Klemmen aufweist.Starting from this prior art, the invention has for its object to form a flat cable connector so that it can be easily connected to both the conductors of a flat cable and a circuit board with a few steps and thus electrically connects these two parts. This connection should be shock and vibration resistant. The solution to this problem arises in a flat cable connector of the type mentioned according to the invention in that the insulation displacement contact is arranged in a housing from a lower part and an upper part and the socket contact and the contact pin pair in a third housing part, openings in the lower part for performing of the socket contact and of the contact pin pair are provided for the purpose of contact with the insulation displacement contact and the housing has slots on the side and the third housing part has clampable and lockable terminals through these.

Der Flachkabelverbinder wird damit in einem mehrteiligen Gehäuse angeordnet. Das oder die Flachkabel befinden sich in dem Gehäuse aus Unter- und Oberteil. In diesem werden die Leiter des Flachkabels in die Schneidklemmkontakte eingeschoben und machen elektrischen Kontakt. Der Buchsenkontakt und das Kontaktstiftpaar befinden sich im dritten Gehäuseteil. Dieses wird mit einer einfachen Bewegung an das aus Unter- und Oberteil bestehende Gehäuse angesetzt und nach Durchschieben seiner Klemmen durch dessen Öffnungen mit diesem verriegelt. Dadurch entsteht eine stoß- und schwingungsfeste Verbindung. Der Flachkabelverbinder kann damit nicht nur in ortsfesten und schwingungsfrei arbeitenden Anlagen verwendet werden. Er kann auch in Kraftfahrzeugen und in Maschinen verwendet werden, in denen durch umlaufende Teile oder Hin- und Herbewegungen Stöße und Schwingungen entstehen. Die einmal entstandene Verbindung ist dauerhaft und hat eine praktisch unendliche Betriebsdauer.The flat cable connector is thus arranged in a multi-part housing. The flat cable or cables are located in the housing made of the lower and upper part. In this, the conductors of the flat cable are inserted into the insulation displacement contacts and make electrical contact. The socket contact and the pair of contact pins are located in the third housing part. This is attached to the housing consisting of the lower and upper part with a simple movement and, after pushing its clamps through the openings, is locked with it. This creates a shock and vibration resistant connection. The flat cable connector can therefore not only be used in fixed and vibration-free systems. It can also be used in motor vehicles and in machines in which shocks and vibrations are caused by rotating parts or back and forth movements. The connection once established is permanent and has a practically infinite operating time.

Die Figuren 1 bis 3 zeigen den erfindungsgemäßen Flachkabelverbinder mit dem Steg 12 und die an dessen beiden Enden angeformten Schneidklemmenkontakte 14 und 16. Diese bestehen jeweils aus den Schenkeln 18 mit einem dazwischenliegenden Schlitz 20. Sämtliche Schenkel 18 sind angespitzt. Die Schenkel 18 werden in bekannter Weise in die Isolation eines Flachkabels hineingedrückt. Die Figuren 1 bis 3 zeigen eine Ausführungsform zum Spleißen von zwei Flachkabeln. An die beiden Seiten des Steges 12 sind Fahnen 22 angeformt. Gemäß der Darstellung in Fig. 3 werden diese Fahnen 22 nach innen umgebogen. Dabei legen sie sich von unten und oben auf ein Flachkabel und umschließen dieses. Hierdurch ergibt sich der erläuterte angestrebte dauerhafte mechanische Halt.Figures 1 to 3 show the flat cable connector according to the invention with the web 12 and the insulation displacement contacts 14 and 16 formed on its two ends. These each consist of the legs 18 with an intermediate slot 20. All legs 18 are pointed. The legs 18 are pressed into the insulation of a flat cable in a known manner. Figures 1 to 3 show an embodiment for splicing two flat cables. Flags 22 are formed on the two sides of the web 12. 3, these flags 22 are bent inwards. They lay on a flat cable from below and above and enclose it. This results in the desired permanent mechanical hold.

Fig. 4 zeigt ein Flachkabel 24 mit einem Leiter 26 größeren und zwei Leitern 28 kleineren Querschnittes. Sie liegen in den ineinander übergehenden Mänteln 30 und 32. Der Leiter größeren Querschnittes dient zur Übertragung von «Kraft»-Strom, während die Leiter kleineren Querschnittes Steuersignale führen. Bis zum Zeitpunkt der vorliegenden Erfindung war es nicht bekannt, solche Flachkabel mit Leitern unterschiedlichen Querschnittes mit Verbindern der hier beschriebenen Gattung zu konfektionieren. Fig. 5 und Fig. 6 zeigen eine solche Anwendung. Fig. 5 zeigt ein Gehäuse aus einem Unterteil 34 und einem Oberteil 36. Im Boden des Unterteiles 34 sind Öffnungen 38 vorgesehen. Seitlich befinden sich Schlitze 40. Fig. 6 zeigt ein drittes Gehäuseteil 42. Dieses weist Klemmen 44 auf. Diese werden in die Schlitze 40 eingeschoben. Im dritten Gehäuseteil wird ein Kontakt 46, der als Buchse ausgebildet sein kann, gehalten. Weiter befinden sich im dritten Gehäuseteil noch zwei ein Paar bildende Kontaktstifte 48. Der Kontakt 46 und die beiden Kontaktstifte 48 stecken in Lötaugen einer Leiterplatte 50. Im oberen Gehäuseteil 36 liegt ein Flachkabel von der in Fig. 4 gezeigten Art. Im Gehäuseteil befinden sich weiter Flachkabelverbinder mit Schneidklemmenkontakten unterschiedlicher Größe. Ein Flachkabelverbinder mit großen Schenkeln 18 liegt an dem großen Leiter 26 an. Die Schenkel 18 sind durch den Mantel 30 durchgestoßen. Die Fahne 22 ist nach rechts umgebogen und liegt von oben auf dem Mantel 30 auf. Rechts zeigt Fig. 5 ein entsprechendes Bild für die beiden kleineren Leiter 28. Hier werden Flachkabelverbinder mit kleineren Schenkeln 18 verwendet. Diese sind durch die Mäntel 32 durchgedrückt. Die Fahnen 22 sind wieder umgebogen und liegen von oben auf den Mänteln 32 auf. Zum Zusammenbau der Anordnung wird das dritte Gehäuseteil 42 mit seinen Klemmen 44 durch die Schlitze 40 durchgeführt. Dabei verrigeln sich die Gehäuseteile miteinander. In diesem zusammengebauten Zustand liegen der Kontakt 46 und die Kontaktstifte 48 an den ihnen zugeordneten Schenkeln 18 an und machen mit diesen elektrischen Kontakt. Dadurch werden die Leiter 26 und 28 mit den nicht dargestellten, auf der Leiterplatte 50 befindlichen Leiterbahnen elektrisch verbunden. Dieser elektrische Kontakt bleibt auch bei Vibrationen erhalten. Die auf das Flachkabel aufgebogenen Fahnen 22 verhindern ein Herauslösen der Schenkel 18 aus dem Flachkabel.Fig. 4 shows a flat cable 24 with a conductor 26 larger and two conductors 28 smaller cross section. They lie in the merging sheaths 30 and 32. The conductor of larger cross-section serves to transmit "force" current during the conductors of smaller cross section carry control signals. Until the present invention, it was not known to assemble such flat cables with conductors of different cross-sections with connectors of the type described here. 5 and 6 show such an application. 5 shows a housing comprising a lower part 34 and an upper part 36. Openings 38 are provided in the bottom of the lower part 34. There are slots 40 on the side. FIG. 6 shows a third housing part 42. This has clamps 44. These are inserted into the slots 40. A contact 46, which can be designed as a socket, is held in the third housing part. Furthermore, there are two contact pins 48 forming a pair in the third housing part. The contact 46 and the two contact pins 48 are in the soldering eyes of a printed circuit board 50. In the upper housing part 36 there is a flat cable of the type shown in FIG. 4 Flat cable connector with insulation displacement contacts of different sizes. A flat cable connector with large legs 18 abuts the large conductor 26. The legs 18 are pierced through the jacket 30. The flag 22 is bent to the right and rests on the jacket 30 from above. 5 shows a corresponding image for the two smaller conductors 28. Flat cable connectors with smaller legs 18 are used here. These are pushed through the jackets 32. 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 bear 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 onto the flat cable prevent the legs 18 from coming out of the flat cable.

Der Querschnitt in Fig. 7 und die Aufsicht in Fig. 8 zeigen eine Kabelverzweigung. Auch hier werden die Schneidklemmenkontakte 14 und 16 von einer Seite in das Flachkabel hineingestoßen, und die Fahnen 22 werden von der anderen Seite auf dieses aufgedrückt.The cross section in FIG. 7 and the top view in FIG. 8 show a cable branch. Again, the insulation displacement contacts 14 and 16 are pushed into the flat cable from one side, and the tabs 22 are pressed onto the flat cable from the other side.
