Description

Die vorliegende Erfindung betrifft einen Mehrfach-Kontaktstifthalter eines modularen Steckverbinders für Telefon- oder Schwachstromanlagen, mit Mitteln zur lötfreien Schneid-Klemm-Andrahtung, welche mindestens einen, auf einen Körper des Kontaktstifthalters niederdrückbaren Schwenkdeckel umfassen, von welchem kontaktseitige Druckrippen abragen, die beim Niederdrücken des Schwenkdeckels auf den Körper in dessen Draht-Einlegeschlitze eindringen und die eingelegten Drähte in Klemmschneiden der Kontaktstifte pressen. The present invention relates to a multiple contact pin holder of a modular Connector for telephone or low-voltage systems, with means for solderless insulation displacement wire, which has at least one, on one body of the contact pin holder depressible swivel cover comprise of which contact-side pressure ribs protrude, which when pressing the Swing lid on the body penetrate into its wire insertion slots and press the inserted wires into the clamping edges of the contact pins.

Solche Mehrfach-Kontaktstifthalter eines modularen Steckverbinders für Telefonoder Schwachstromanlagen sind bereits durch die EP-A-0 310 832 oder die EP-A-0 427 132 bekannt geworden, deren Mitteln zur lötfreien Schneid-Klemm-Andrahtung einen, auf einen Körper des Kontaktstifthalters niederdrückbaren Schwenkdeckel umfassen, von welchem kontaktseitige Druckrippen abragen, die beim Niederdrücken des Schwenkdeckels auf den Körper in dessen Draht-Einlegeschlitze eindringen und die eingelegten Drähte in Klemmschneiden der Kontaktstifte pressen.Such multiple contact pin holder of a modular connector for telephone or Low-voltage systems are already covered by EP-A-0 310 832 or EP-A-0 427 132 become known, their means for solderless insulation displacement wire one that can be pressed onto a body of the contact pin holder Include swivel cover, from which contact-side pressure ribs protrude, the when pressing the swivel cover onto the body in its wire insertion slots penetrate and the inserted wires in clamping edges of the Press contact pins.

Problematisch ist bei solchen Anordnung jedoch, dass die eingelegten Drähte vor dem Einpressen in die Draht-Einlegeschlitze relativ leicht verspringen und so die Einlegearbeit wiederholt werden muss. Ferner ist nachteilig, dass die Schwenkdeckel nach deren Niederdrücken verbleiben müssen, um die eingepressten Drähte zu fixieren.However, the problem with such an arrangement is that the inserted wires jump relatively easily before being pressed into the wire insertion slots and such the inlay work must be repeated. Another disadvantage is that the Swivel covers must remain after they have been pressed down in order to press them in Fix wires.

Aufgabe der Erfindung ist deshalb die Schaffung einer, die genannten Nachteile behebenden Ausführungsform eines Mehrfach-Kontaktstifthalters der vorgenannten Art.The object of the invention is therefore to create one, the disadvantages mentioned corrective embodiment of a multiple contact pin holder of the aforementioned Art.

Dies wird erfindungsgemäss dadurch erreicht, dass die Draht-Einlegeschlitze seitliche, übereinander angeordnete Drahthaltenocken aufweisen, von welchen mindestens ein Drahthaltenocken sich im Draht-Einlege-Bereich befindet, um einen eingelegten Draht zu positionieren und mindestens ein anderer Drahthaltenocken sich im Klemmschneide-Bereich befindet, um den in die Klemmschneide eingepressten Draht zu fixieren. This is achieved according to the invention in that the wire insertion slots have lateral, superimposed wire holding cams, of which at least one wire holding cam is located in the wire insertion area to position an inserted wire and at least one other wire holding cam is in the clamping cutting area, around the in the clamping cutting edge to fix pressed wire.

Somit kann weder ein eingelegter noch ein eingepresster Draht aus seinem Einlegeschlitz heraustreten, unabhängig von irgendwelchen Sperrfunktionen des Schwenkdeckels.Thus, neither an inserted nor a pressed one Step the wire out of its insertion slot, independently of any locking functions of the swivel cover.

Um zudem dem immer geringeren zur Verfügung stehenden Platzbedarf Rechnung zu tragen und zudem den Schwenkdeckel in seiner Handhabung zu verbessern, besteht eine bevorzugte Ausführungsform darin, dass der Schwenkdeckel mit Stegmitteln an seiner Rückseite einsetzbar und schwenkbar eine Schulter an der Rückseite des Körpers untergreift und ferner, dass der Schwenkdeckel in seiner Einpresslage vom Körper lösbar seitlich klemmend oder durch Einrastmittel gehalten ist; dass ferner der Schwenkdeckel in seiner Offenlage höchstens bündig ist mit der Rückseite des Körpers und dass der Schwenkdeckel ein mehrfach verwendbares Hilfswerkzeug zum Einpressen von Drähten in die Klemmschneiden von mehreren Kontaktstifthaltern ist.In addition, to the ever less available Space requirements and the swivel cover improving its handling is a preferred one Embodiment in that the swivel cover with web means insertable at the back and swiveling one Under the shoulder on the back of the body and further, that the swivel cover in its press-in position from the body releasably clamped to the side or held by snap-in means is; that further the swivel lid in its open position is at most flush with the back of the body and that the swivel cover is a multi-use auxiliary tool for pressing wires into the clamping cutting edges of several contact pin holders.

Eine beispielsweise Ausführungsform des Erfindungsgegenstandes ist nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

An example embodiment of the subject matter of the invention is explained in more detail below with reference to the drawing. Show it:
Fig. 1
in a diagrammatic representation in partial section an inventive multiple contact pin holder with an open swivel cover;
Fig. 2
the contact pin holder of Figure 1 with the closed swivel cover. and
Fig. 3
Detail and in a diagram-like, enlarged representation of a wire insertion slot of the arrangement according to FIG. 1.

Der in den Fig. 1 und 2 veranschaulichte Mehrfach-Kontaktstifthalter 1 stellt sich in der Regel als Kontaktleiste dar, welche für jeden Draht 20 einen querlaufenden Draht-Einlegeschlitz 5 aufweist. In jeden dieser Schlitze 5 ragt querstehend die Klemmschneide 6 eines abragenden Kontaktstiftes 7 hinein, wobei benachbarte Kontaktstifte 7 in der Regel gegeneinander versetzt sind (nicht gezeigt).The multiple contact pin holder illustrated in FIGS. 1 and 2 1 usually turns out to be a contact bar which has a transverse wire insertion slot for each wire 20 5 has. 5 protrudes into each of these slots transversely the clamping edge 6 of a protruding contact pin 7 into it, with adjacent contact pins 7 in the Are usually offset from each other (not shown).

Soweit sind solche Mehrfach-Kontaktstifthalter bekannt. Weiter ist bekannt, dass die Mittel zur Schneid-Klemm-Andrahtung auf den Körper 2 des Kontaktstifthalters 1 einen niederdrückbaren Schwenkdeckel 3 umfassen. Von diesem Schwenkdeckel 3 ragen in modulem Abstand kontaktseitig Druckrippen 4 ab, die beim Niederdrücken des Schwenkdeckels 3 auf den Körper 2 in dessen Draht-Einlegeschlitze 5 eindringen und die eingelegten Drähte 20 in die Klemmschneiden 6 der Kontaktstifte 7 pressen. So far, such multiple contact pin holders are known. It is also known that the means for insulation displacement connection on the body 2 of the contact pin holder 1 depressible swivel cover 3 include. Of this Swivel cover 3 protrude on the contact side at a modular distance Pressure ribs 4 from when pressing down the swivel cover 3 penetrate the body 2 into its wire insertion slots 5 and the inserted wires 20 in the clamping cutting edges Press 6 of the contact pins 7.

Wie bereits einleitend ausgeführt und besonders der Fig. 3 entnehmbar, ist es erfindungswesentlich, dass die Draht-Einlegeschlitze 5 seitliche, übereinander angeordnete Drahthaltenocken 11,12 aufweisen, von welchen mindestens ein Drahthaltenocken 11 sich im Draht-Einlege-Bereich befindet, um einen eingelegten Draht zu positionieren und mindestens ein anderer Drahthaltenocken 12 sich im Klemmschneide-Bereich befindet, um den in die Klemmschneide eingepressten Draht zu fixieren.As already stated in the introduction and in particular in FIG. 3 Removable, it is essential to the invention that the wire insertion slots 5 side, one above the other Have wire holding cams 11, 12 of which at least a wire holding cam 11 is located in the wire insertion area, to position an inserted wire and at least one other wire-holding cam 12 in Clamping edge area is located around the in the clamping edge to fix pressed wire.

Dies verhindert zunächst, dass die eingelegten Drähte vor dem Einpressen in die Draht-Einlegeschlitze verspringen können und so die Einlegearbeit wiederholt werden müsste. Ferner ist es nicht mehr notwendig, dass die Schwenkdeckel nach deren Niederdrücken verbleiben müssen, um die eingepressten Drähte zu fixieren.This initially prevents the wires from being inserted jump into the wire insertion slots and the inlay work would have to be repeated. Furthermore, it is no longer necessary for the swivel cover after they have been depressed must remain to the pressed Fix wires.

Um zudem dem immer geringeren, zur Verfügung stehenden Platzbedarf Rechnung zu tragen und zudem den Schwenkdeckel in seiner Handhabung zu verbessern, besteht eine bevorzugte Ausführungsform darin, dass der Schwenkdeckel 3 mit Stegmitteln 9 an seiner Rückseite einsetzbar und schwenkbar eine Schulter 8 an der Rückseite des Körpers 2 untergreift, wie das Fig. 1 im Einzelnen zeigt. Hierbei ist es von Bedeutung, dass der Schwenkdeckel 3 in seiner Offenlage die Rückseite des Körpers 2 nicht überragt, also höchstens mit dieser Rückseite bündig ist.In addition to the ever smaller, available Space requirements and the swivel cover improving its handling is a preferred one Embodiment in that the swivel cover 3 with web means 9 insertable on its back and swiveling engages under a shoulder 8 on the back of the body 2, as shown in Fig. 1 in detail. It is important here that the swivel cover 3 in its open position Back of the body 2 is not towered over, at most with this back is flush.

Weiter ist es vorteilhaft, wenn der Schwenkdeckel 3 in seiner Einpresslage vom Körper 2 lösbar seitlich klemmend oder durch Einrastmittel gehalten ist (nicht näher veranschaulicht).It is also advantageous if the swivel cover 3 in its press-in position from the body 2 releasably clamping laterally or is held by latching means (not illustrated in detail).

Dadurch, dass die eingepressten Drähte 20 von den unteren Nocken 12 niedergehalten werden, ist es nunmehr möglich, den Schwenkdeckel 3 als ein mehrfach verwendbares Hilfswerkzeug zum Einpressen von Drähten in die Klemmschneiden von mehreren Kontaktstifthaltern zu verwenden.The fact that the pressed wires 20 from the lower Cams 12 are held down, it is now possible the swivel cover 3 as a reusable auxiliary tool for pressing wires into the clamping blades to be used by several contact pin holders.

Aus dem Vorbeschriebenen ergibt sich somit ein Mehrfach-Kontaktstifthalter eines modularen Steckverbinders für Telefon- oder Schwachstromanlagen, mit Mitteln zur lötfreien Schneid-Klemm-Andrahtung, bei dem das Hauptproblem der Fixierung die Drähte resp. Adern vor und nach der Schneid-Klemm-Andrahtung optimal sowie herstellungs- und handhabungstechnisch relativ einfach gelöst ist.A multiple contact pin holder thus results from the above a modular connector for Telephone or low-voltage systems, with means for solderless Insulation displacement wiring, in which the main problem the fixation the wires respectively. Veins before and after the Insulation displacement wire optimal as well as manufacturing and is relatively easy to handle in terms of handling.
