Fig. 1a zeigt eine Darstellung eines Abschnittes eines bei allen dargestellten Ausführungen beschaltbaren durchgehenden Flachkabels 1 mit zwei parallel zueinander angeordneten Leitern 2, 3, die in einen umgebenden Mantel 4 aus Isolierstoff eingebettet sind. Der Isolierstoffmantel 4 ist konturiert ausgebildet und weist einerseits obere und untere Kerben 5, 6 zwischen den Leitern 2, 3 auf und andererseits einen Steg 7 zur Polarisierung bzw. optischen Unterscheidung der zwei Leiter 2, 3. Fig. 1a shows a representation of a portion of a connectable in all the illustrated embodiments continuous flat cable 1 with two mutually parallel conductors 2, 3, which are embedded in a surrounding jacket 4 of insulating material. The Isolierstoffmantel 4 is formed contoured and has on the one hand upper and lower notches 5, 6 between the conductors 2, 3 and on the other hand a web 7 for polarization or optical discrimination of the two conductors 2, 3rd

Zur Realisierung einer T-Stückartigen Abzweigung bzw. zur Realisierung eines elektrischen Anschlusses an das Kabel 1 ohne ein Durchtrennen des Kabels und ohne ein Entfernen des Kabelmantels dienen die in Fig. 1 bis 12 dargestellten Anschlussvorrichtungen 8, die kostengünstig ausgebildet sind und den Abdichtungsstandard "IP 20" erfüllen.To realize a tee-like branch or to realize an electrical connection to the cable 1 without a severing of the cable and without removing the cable sheath serve in Fig. 1 to 12 illustrated connecting devices 8, which are designed inexpensively and meet the sealing standard "IP 20".

Die Anschlussvorrichtungen 8 weisen jeweils ein Grundgehäuse 9 aus Isolierstoff auf sowie eine mehrteilige Betätigungseinrichtung 10, die dazu dient, das Flachkabel 1 bzw. die zwei Leiter 2, 3 in isolationsdurchdringende Kontakte 11, 12 ― hier gabelförmig mit Kontaktschneiden - im Grundgehäuse 9 einzudrücken. Die isolationsdurchdringenden Kontakte können auch als isolationsdurchstechende Kontakte ― auch Piercingkontakte genannt ― ausgebildet sein, was bei mehradrigen Leiter besonders vorteilhaft ist (Fig. 2 bis 12).The connecting devices 8 each have a base housing 9 made of insulating material and a multi-part actuator 10, which serves to press the flat cable 1 and the two conductors 2, 3 in isolationsdurchdringende contacts 11, 12 - here forked with contact blades - in the base housing 9. The insulation-penetrating contacts can also be designed as insulation piercing contacts - also called piercing contacts - which is particularly advantageous in the case of multi-core conductors ( Fig. 2 to 12 ).

Die isolationsdurchdringenden Kontakte 11,12 der Fig. 1 sind jeweils in einem mündungsartigen Bereich 13 mit Schneiden zur Isolationsdurchdringung versehen und weisen einen Kontaktschlitz 14 zum Kontaktieren der Leiter auf. Die zwei IDC-Kontakte 11,12 sind ähnlich ausgebildet und im Grundgehäuse 9 in Leiterrichtung axial und radial zueinander versetzt angeordnet. Sie sind ferner hier in vorteilhafter und kostengünstiger Weise einstückig über Stromschienenabschnitte 15 mit Kontakttulpen 16 verbunden, die zum Anschluss externer (hier nicht dargestellter) Leiter in einen nach außen offenen Kragen 17 des Gehäuses 8 ragen, der mit einem korrespondierenden Buchsenteil mit Kontaktstiften (hier nicht dargestellt) zusammensteckbar ist.The insulation piercing contacts 11,12 of Fig. 1 are each provided in a muzzle-like region 13 with cutting for insulation penetration and have a contact slot 14 for contacting the conductors. The two IDC contacts 11,12 are similarly formed and arranged offset in the base housing 9 in the conductor direction axially and radially to each other. They are also here in an advantageous and cost-effective manner integrally connected via busbar sections 15 with contact tulips 16, which protrude to connect external (not shown here) head in an outwardly open collar 17 of the housing 8, with a corresponding socket part with contact pins (not here shown) can be plugged together.

Die Betätigungseinrichtung 10 ist relativ zum Grundgehäuse 9 beweglich und zumindest in einer Offenstellung und in einer Geschlossenstellung nach dem Einlegen des Kabels 1 positionierbar, was die Handhabung vereinfacht. Das Kabel kann dabei am Grundgehäuse 9 oder an der Betätigungseinrichtung 10 vorzugsweise auch vorverrastet werden.The actuator 10 is movable relative to the base housing 9 and at least in an open position and in a closed position after insertion of the cable 1 positionable, which simplifies handling. The cable can preferably also be pre-locked on the base housing 9 or on the actuating device 10.

Das Grundgehäuse 9 der Fig. 1 ist hülsenartig, hier zylindrisch, ausgebildet und mit einem seitlichen Schlitz 18 versehen, in den das Flachkabel einschiebbar ist.The basic housing 9 of Fig. 1 is sleeve-like, here cylindrical, formed and provided with a lateral slot 18 into which the flat cable is inserted.

Die Betätigungseinrichtung 10 weist einen zylindrischen Basiskörper 19 nach Art eines Schiebeelementes auf, der seitlich ebenfalls mit einem Schlitz 20 versehen ist und der teleskopartig in einer axialen Öffnung oder Bohrung 21 des Grundgehäuses 9 verschieblich geführt ist.The actuating device 10 has a cylindrical base body 19 in the manner of a sliding element which is laterally also provided with a slot 20 and which is telescopically guided in an axial opening or bore 21 of the base housing 9 slidably.

Zum Kontaktieren ist das Flachkabel 1 von der Seite her radial in den Schlitz 18 des Grundgehäuses 9 und in den hiermit fluchtenden Schlitz 20 der Betätigungseinrichtung einzuführen und dann der Basiskörper 19 axial in der Bohrung zu verschieben, bis die Kontaktierung erfolgt.To contact the flat cable 1 is inserted from the side radially into the slot 18 of the base housing 9 and in the aligned therewith slot 20 of the actuator and then move the base body 19 axially in the bore until the contact is made.

Das Verschieben des Basiskörpers 19 in der Öffnung 21 wird mittels eines Schraubelementes realisiert, das mit einem Gewinde am oder im Grundgehäuse 9 zusammenwirkt.The displacement of the base body 19 in the opening 21 is realized by means of a screw which cooperates with a thread on or in the base housing 9.

Das Schraubelement ist hier als Deckel 22 realisiert, der nach Art einer Schraubkappe ausgestaltet ist, die ein Innengewinde aufweist und mit einem korrespondierenden Außengewinde 23 des Grundgehäuses 9 zusammenwirkt. Beim Zuschrauben wird der zylindrische Betätigungskörper 19 in der Bohrung 21 verschoben, bis das eingelegte und zuvor vorzugsweise in einer Rastkontur im Schlitz 20 vorverrastete Kabel von den IDC-Kontakten durchdrungen und der Kontakt hergestellt wird. Der Schlitz 18 im Grundgehäuse ist axial so lang, dass ein genügendes axiales Verschieben des Flachkabels 1 im Schlitz möglich ist, um das Flachkabel zu kontaktieren. Denkbar ist auch eine Vorverrastung durch Rasthaken.The screw is realized here as a cover 22 which is designed in the manner of a screw cap which has an internal thread and cooperates with a corresponding external thread 23 of the base housing 9. When screwing the cylindrical actuator body 19 is moved in the bore 21 until the inserted and previously preferably pre-latched in a locking contour in the slot 20 cable penetrated by the IDC contacts and the contact is made. The slot 18 in the base housing is axially so long that a sufficient axial displacement of the flat cable 1 in the slot is possible to contact the flat cable. It is also conceivable Vorverrastung by locking hooks.

Die Fig. 2 - 11 zeigen Ausführungsbeispiele, bei denen das aus Montagegründen vorzugsweise zweistückige Grundgehäuse 9 mit zwei miteinander verrastbaren Gehäusehälften rechtwinklig zueinander ausgerichtete Außenflächen aufweist. Andere Formen sind ebenfalls denkbar. Die dargestellte Ausgestaltung ist aber besonders kompakt und montagefreundlich.The Fig. 2 - 11 show embodiments in which the assembly reasons preferably two-piece base housing 9 having two mutually latchable housing halves perpendicular to each other aligned outer surfaces. Other shapes are also conceivable. The illustrated embodiment is particularly compact and easy to install.

Das Grundgehäuse 9 der Fig.2, das wiederum aus isolierendem Kunststoff besteht, weist wie das Ausführungsbeispiel der Fig. 1 den seitlichen Schlitz 18 auf, in den das Flachkabel 1 einschiebbar ist.The basic housing 9 of Fig.2 , which in turn consists of insulating plastic, has as the embodiment of Fig. 1 the lateral slot 18, in which the flat cable 1 is inserted.

Die Betätigungseinrichtung 10 weist wiederum einen schlittenartigen Basis- und Betätigungskörper 19 auf, der seitlich ebenfalls mit dem Schlitz 20 versehen ist und der teleskopartig in der Bohrung 21 des Grundgehäuses 9 senkrecht zum zu kontaktierenden Flachkabel verschieblich geführt ist.The actuator 10 in turn has a slide-like base and actuator body 19 which is also provided laterally with the slot 20 and which is guided telescopically in the bore 21 of the base housing 9 perpendicular to the flat cable to be contacted.

Zum Kontaktieren ist das Flachkabel 1 von der Seite her radial in den Schlitz 18 des Grundgehäuses und in den hiermit fluchtenden Schlitz 20 der Betätigungseinrichtung einzuführen und dann der Basiskörper 19 axial in der Bohrung zu verschieben, bis die Kontaktierung erfolgt.To contact the flat cable 1 is inserted from the side radially into the slot 18 of the base housing and in the aligned therewith slot 20 of the actuator and then move the base body 19 axially in the bore until the contact is made.

Das Verschieben des Basis- bzw. Betätigungskörpers 19 in der Öffnung 21 wird hier nicht wie in Fig. 1 mit einem Deckel sondern mit Hilfe einer Schraube 24 als Schraubelement ― siehe auch Fig. 9 - realisiert, die ein Außengewinde 25 aufweist und mit einem korrespondierenden Innengewinde 26 in einem ersten axialen Bereich der Bohrung 21 des Grundgehäuses 9 zusammenwirkt.The displacement of the base or operating body 19 in the opening 21 is not here as in Fig. 1 with a cover but with the help of a screw 24 as a screw - see also Fig. 9 - realized, which has an external thread 25 and cooperates with a corresponding internal thread 26 in a first axial region of the bore 21 of the base housing 9.

Beim Beschalten bzw. Einschrauben der madenartig bzw. bolzenartig ohne Schraubenkopf ausgebildeten Schraube 24 drückt diese auf den in axialer Verlängerung der Schraube 24 angeordneten schlittenartigen Betätigungskörper 19 und verschiebt diesen in der Bohrung 21, bis das Kabel von den isolationsdurchdringenden Kontakten 25 durchdrungen und der Kontakt hergestellt wird.When wiring or screwing the maggot-like or bolt-like without screw head formed screw 24 presses them on the arranged in the axial extension of the screw 24 slide-like actuator body 19 and moves it in the bore 21 until the cable penetrated by the insulation piercing contacts 25 and made the contact becomes.

Der Schlitz 18 im Grundgehäuse 9 weist eine größere axiale Erstreckung senkrecht zur Erstreckung des Flachkabels aufweist als der Schlitz 20 im Basiskörper 19, um eine genügende Verschiebbarkeit des Kabels zu realisieren.The slot 18 in the base housing 9 has a greater axial extent perpendicular to the extension of the flat cable than the slot 20 in the base body 19 in order to realize a sufficient displaceability of the cable.

Die Kontakte sind hier als isolationsdurchdringende Piercingkontakte 30 ausgestaltet, an die sich jeweils ein Leiterstift 31 anschließt, die jeweils aus dem Grundgehäuse 9 vorstehen und an denen das Grundgehäuse 9 auf einer Leiterplatte montierbar ist (hier nicht dargestellt). Die Leiterstifte können je nach Ausgestaltung gerade oder winklig ausgebildet sein (Fig. 1, Fig. 11), was es erlaubt, Ausgestaltungen verschiedener Art zu realisieren, um die Anschlußvorrichtung auf der Leiterplatte entweder seitlich oder senkrecht nach oben auszurichten.The contacts are configured here as insulation piercing piercing contacts 30, to each of which a conductor pin 31 connects, each projecting from the base housing 9 and where the base housing 9 is mounted on a circuit board (not shown here). The conductor pins can be formed straight or angled depending on the configuration ( Fig. 1 . Fig. 11 ), which allows embodiments of various kinds to be realized to align the terminal device on the circuit board either laterally or vertically upwards.

Die Piercingkontakte durchsetzen Löcher oder Schlitze 32 im Basiskörper und sind im Grundgehäuse fixiert, so dass der Basiskörper auf den Piercingkontakten verschieblich ist.The piercing contacts pass through holes or slots 32 in the base body and are fixed in the base housing, so that the base body is displaceable on the piercing contacts.

Das Grundgehäuse 9 mit relativ großen ebenen ― hier zueinander rechtwinkligen - Außenflächen eignet sich hervorragend zur Nutzung von Bestückungswerkzeugen beispielsweise in Pick-and-Place-Techniken.The basic housing 9 with relatively large planes - here mutually perpendicular - outer surfaces is ideal for the use of placement tools, for example in pick-and-place techniques.

An der Oberfläche des Grundgehäuses 9 ist eine genügend große Fläche für Farbkodierungen oder dgl. vorhanden.On the surface of the base housing 9 is a sufficiently large area for color coding or the like. Exists.

Ein Zeigerelement 27 an der von außen erkenntlichen Schraube 24 erlaubt ― ggf. in Kombination mit einer Gehäusemarkierung oder Beschriftung - eine leichte Erkennbarkeit des Schaltzustandes von Außen. Hier schließt sich das Zeigerelement 27 seitlich an einen Betätigungsschlitz 28 zum Ansetzen eines Werkzeugs, insbesondere eines Schraubendrehers an.A pointer element 27 on the externally visible screw 24 allows - possibly in combination with a housing mark or label - an easy recognizability of the switching state from the outside. Here, the pointer element 27 connects laterally to an actuating slot 28 for attaching a tool, in particular a screwdriver.

Vorzugsweise ist das Gewinde 25, 26 des Schraubelementes selbsthemmend ausgelegt, was sowohl die Offenstellung als auch die beschaltete Position sichert und insbesondere in Einbausituationen vorteilhaft ist, in denen die gesamte Vorrichtung Vibrationen ausgesetzt ist.Preferably, the thread 25, 26 of the screw is self-locking, which ensures both the open position and the switched position and is particularly advantageous in installation situations in which the entire device is exposed to vibration.

Die Schraube 24 als das auf den Basiskörper bzw. das Schieberelement einwirkende Glied erlaubt die Abstützung der beim Be- und Entschalten auftretenden hohen Kräfte direkt im Gehäuse.The screw 24 as the member acting on the base body or the slider element allows the support of the high forces occurring during loading and unloading directly in the housing.

Der Deckel 22 der Fig. 1 als Schraubelement kann vorzugsweise manuell betätigt werden. Bei der Schraube 24 wird eine Schraubendreherbetätigung bevorzugt, die einfach, schnell und sicher durchführbar ist. Bevorzugt ist das Gewinde so ausgelegt, dass mit einer weniger als einer ganzen Umdrehung, insbesondere einer halben Umdrehung um 180°, eine Be- oder Entschaltung des Kontaktes schnell und einfach möglich ist.The lid 22 of Fig. 1 as a screw can preferably be operated manually. In the screw 24, a screwdriver operation is preferred, which is simple, quick and safe to carry out. Preferably, the thread is designed so that with a less than a complete revolution, in particular a half turn by 180 °, a switching on or disconnection of the contact is quick and easy.

Rastkonturen 28 (Fig. 10) im Schlitz 18 des Betätigungselementes ermöglichen eine sichere Vorverrastung des zu kontaktierenden durchgehenden Kabels.Lock contours 28 ( Fig. 10 ) in the slot 18 of the actuator allow a secure Vorverrastung to be contacted continuous cable.

Im Grundgehäuse können seitlich des Schlitzes des Betätigungselementes Vorsprünge 29 oder dgl. ausgebildet sein, die zur Realisierung einer Zugentlastung und zur Litzenabstützung dienen.In the base housing may laterally of the slot of the actuating element projections 29 or the like. Be formed, which serve to realize a strain relief and Litzenabstützung.

Damit das Schraubelement das Basiselement 19 und damit den Leiter 1 wieder vom Kontakt 30 lösen kann, ist es vorteilhaft, wenn das Schraubelement und das Basiselement 19 formschlüssig ineinander greifen. Dies kann beispielsweise ― wie in Fig. 7 oder 10 zu erkennen - durch eine nut-/federartige Verbindung zwischen der bolzenartigen Schraube (ohne Spitze) 24 und dem Basiselement 19 erfolgen.So that the screw element can release the base element 19 and thus the conductor 1 again from the contact 30, it is advantageous if the screw element and the base element 19 engage in one another in a form-fitting manner. This can for example - as in Fig. 7 or 10 to recognize - done by a nut- / spring-like connection between the bolt-like screw (without tip) 24 and the base member 19.

Realisierbar ist dies auf einfache Weise beispielsweise mit einem T-förmigen Ansatz 33 am Basiselement 19 erreicht werden, der in eine korrespondierende Nut am Basiselement eingreift. Derart zieht die Schraube 24 beim Lösen das Basiselement 19 und damit auch den Leiter 1 wieder vom Kontakt 30 fort und löst den Leiter 1 nach Art einer Schnellentriegelung aus der Kontaktstellung.This can be achieved in a simple manner, for example with a T-shaped projection 33 on the base element 19, which engages in a corresponding groove on the base element. Thus, the screw 24 pulls when loosening the base member 19 and thus also the conductor 1 again from the contact 30 and dissolves the conductor 1 in the manner of a quick release of the contact position.
