Abstract

The electrical connecting element for a connecting of fine wire cables (strands) consists of a contact pin having preferably points at both its ends and a radially projecting abutment flange on the shaft of the pin which contact pin penetrates through insulations. A shoulder between tip and shaft ensures that the pin which has been pressed in can not be torn out and the flange acts for a limiting of the depth of penetration.

Description

Die vorliegende Erfindung betrifft ein Element zur Erstellung einer elektrisch leitenden Verbindung mit einer feindrähtigen Aderseele in einem Kabel, insbesondere einem Flachbandkabel und im besonderen ein derartiges Element zur Erstellung einer elektrisch leitenden Verbindung zwischen feindrähtigen Aderseelen in übereinanderliegend angeordneten Kabeln, insbesondere Flachbandkabeln.The present invention relates to an element for creation an electrically conductive connection with a fine wire Core in a cable, especially a ribbon cable and in particular such an element for creating a electrically conductive connection between fine-wire cores in cables arranged one above the other, in particular Ribbon cables.

Zur Erstellung elektrischer Verbindungen der vorstehend beschriebenen Art sind die unterschiedlichsten, mehr oder weniger aufwendigen Vorrichtungen, wie z.B. Verbindungs- oder Abzweigdosen bekannt.To make electrical connections to those described above Kind are the most different, more or less complex devices, e.g. Junction boxes or junction boxes known.

Aufgabe der vorliegenden Erfindung war es, eine wesentlich einfachere elektrische und mechanische Verbindung mit bzw. zwischen feindrähtigen Leitern in Kabeln, insbesondere Flachbandkabeln zu schaffen, wobei die Verbindung auch auf kleinstem Raum sicher und sehr schnell erstellbar sein sollte.The object of the present invention was to provide a much simpler one electrical and mechanical connection with or between finely stranded conductors in cables, in particular ribbon cables to create, the connection even on the smallest Space should be safe and very quick to create.

Diese Aufgabe wird nun bei einem Verbindungselement der eingangs definierten Art erfindungsgemäss durch die Merkmale des kennzeichnenden Teils von Anspruch 1 (für einen einfachen Anschluss an einen Leiter) bzw. von Anspruch 2 (für die Verbindung von Leitern in übereinanderliegenden Kabeln) gelöst.This task is now the case with a connecting element defined type according to the invention by the features of characterizing part of claim 1 (for a simple connection to a conductor) or of claim 2 (for the connection from conductors in cables one on top of the other).

Besondere Ausführungsformen des Erfindungsgegenstandes sind in den abhängigen Ansprüchen definiert.Particular embodiments of the subject matter of the invention are in the dependent claims.

Die erfindungsgemässe Lösung wird weitgehend auch dadurch ermöglicht, als die heutigen Kabel sehr präzis gefertigt sind (genaue Position der Leiteradern und deren Isolation im Kabelmantel). The solution according to the invention is also largely made possible by than today's cables are made very precisely (exact position of the conductor wires and their insulation in the cable jacket).

Die Erfindung wird nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels noch etwas näher erläutert. Es zeigt:

Fig. 1
einen Querschnitt durch zwei übereinanderliegende fünfadrige Flachkabel mit einem Element zum Verbinden der Leiteradern, und
Fig. 2
rein schematisch die Anordnungsmöglichkeiten der Verbindungsstellen für die Verbindung aller Adern.
The invention is explained in more detail below with reference to an embodiment shown in the drawing. It shows:
Fig. 1
a cross section through two superimposed five-wire flat cable with an element for connecting the conductor wires, and
Fig. 2
The arrangement possibilities of the connection points for the connection of all wires are purely schematic.

Figur 1 der Zeichnung zeigt zwei übereinanderliegende Flachkabel 1, 2 mit jeweils fünf Leiteradern (feindrähtige bzw. Litzenadern) 3 - 7 die von einer Aderisolation 3' - 7' umgeben in den Kabelmantel 1' bzw. 2' eingebettet sind.Figure 1 of the drawing shows two superimposed flat cables 1, 2 with five conductor wires each (fine-stranded or stranded wires) 3 - 7 surrounded by a wire insulation 3 '- 7' in the cable sheath 1 'or 2' are embedded.

Zur sicheren elektrischen Verbindung der Adern 3-3, 4-4 ... der beiden Kabel 1, 2 sind elektrisch leitende (metallische) Verbindungselemente 8 vorgesehen. Diese bestehen aus einem nagelförmigen Kontaktstift mit jeweils an jedem Ende vorgesehener Nagelspitze 10, 11 und dazwischenliegendem Nagelschaft 9. Der Basisdurchmesser der Nagelspitzen 10, 11 ist etwas grösser als der Durchmesser des Nagelschaftes, so dass jeweils eine Schulter gebildet wird.For safe electrical connection of wires 3-3, 4-4 ... the Both cables 1, 2 are electrically conductive (metallic) connecting elements 8 provided. These consist of a nail-shaped Contact pin with one at each end Nail tip 10, 11 and intermediate nail shaft 9. The The base diameter of the nail tips 10, 11 is slightly larger than the diameter of the nail shaft, making one shoulder each is formed.

Auf dem Nagelschaft 9 in vorbestimmtem Abstand von den Nagelspitzen 10, 11 ist ein radial abstehender Flansch 12 vorgesehen. Die Funktion sowohl der Schulter an der Spitzenbasis als auch des Flansches 12 geht aus nachfolgender Beschreibung hervor:On the nail shaft 9 at a predetermined distance from the nail tips 10, 11 a radially projecting flange 12 is provided. The function of both the shoulder at the tip base as well flange 12 is also evident from the following description:

Um auf kleinstem Raum in kürzester Zeit eine sichere elektrische und mechanische Verbindung zwischen feindrähtigen Litzen-Flachbandkabeln zu erstellen, wurde das vorstehend beschriebene Verbindungselement entwickelt (Kontaktnagel). Mit einem Werkzeug (nicht dargestellt) werden beispielsweise bei einem fünfadrigen Flachbandkabel 2 die Kontaktnägel 8 im richtigen Abstand voneinander gehalten und dann mittels einer Vorrichtung (nicht dargestellt) zuerst in das eine Flachbandkabel 2 gepresst und dann wird das andere Flachbandkabel 1 auf die vorstehenden Kontaktnägel 8 aufgepresst. Die Spitzen 10, 11 der Kontaktnägel 8 durchstechen den Kabelmantel 1' und die Aderisolation 3' - 7' und dringen in die feindrähtige Aderseele 3 - 7 ein, ohne aber die Aderisolation 3' - 7' auf der entgegengesetzten Seite zu durchbohren. Um zu verhindern, dass die so miteinander verbundenen Flachbandkabel 1, 2 von den Kontaktnägeln 8 abgleiten, wenn die Pressvorrichtung entfernt wird und der Pressdruck aufhört, ist der Durchmesser an der Basis der Nagelspitzen 10, 11 etwas grösser als der Durchmesser des Nagelschafts 9. Der etwas grössere Durchmesser an der Basis der Nagelspitzen 10, 11 wirkt wie ein Widerhaken im Geflecht der feindrähtigen Aderseele 3 - 7. Die Adern vom Hauptleiter zum Abzweigleiter sind elektrisch und mechanisch miteinander verbunden und die Flachbandkabel können sich nicht von selbst von den Kontaktnägeln 8 lösen.To ensure a safe electrical in the smallest space in the shortest possible time and mechanical connection between finely stranded flat ribbon cables to create, has been described above Connection element developed (contact nail). With one tool (not shown) are, for example, at a five-core ribbon cable 2 the contact nails 8 in the correct Keep distance from each other and then by means of a device (not shown) first pressed into a ribbon cable 2 and then the other ribbon cable 1 to the above Contact nails 8 pressed on. The tips 10, 11 of the Contact nails 8 pierce the cable jacket 1 'and the wire insulation 3 '- 7' and penetrate into the fine wire core 3 - 7 one, but without the wire insulation 3 '- 7' on the opposite Pierce side. To prevent them from doing so interconnected ribbon cables 1, 2 from the contact nails 8 slide when the press device is removed and the pressing pressure stops, is the diameter at the base of the Nail tips 10, 11 slightly larger than the diameter of the nail shaft 9. The slightly larger diameter at the base of the Nail tips 10, 11 act like a barb in the braid finely stranded core 3 - 7. The wires from the main conductor to the Branch conductors are electrically and mechanically connected to each other and the ribbon cables cannot go by themselves loosen the contact pins 8.

Da bei heutigen Kabeln deren "Geometrie" mit hoher Präzision bekannt ist, kann durch passende Anordnung des Flansches 12 die Eindringtiefe des Kontaktnagels 8 festgelegt werden (so dass der Kontaktnagel 8 nur in die Adern 3 - 7 eindringt, deren Isolation 3' - 7' jedoch im Bereich der Spitzen 10, 11 (nach dem Einpressen) nicht durchdringt.Because with today's cables their "geometry" with high precision is known, can by the appropriate arrangement of the flange 12 Penetration depth of the contact nail 8 can be set (so that the contact nail 8 only penetrates into the wires 3 - 7, their insulation 3 '- 7', however, in the area of the tips 10, 11 (after the Pressing) does not penetrate.

Figur 2 der Zeichnung zeigt (im Vergleich zu Fig. 1 verändertem Massstab) zwei Anordnungsmöglichkeiten der Verbindungselemente zum Verbinden der Adern von zwei übereinander gelegten fünfadrigen Kabeln A-B-C-D-E oder A-B-C'-D'-E'.Figure 2 of the drawing shows (compared to Fig. 1 changed Scale) two possible arrangements of the connecting elements for connecting the wires of two superimposed five-wire Cables A-B-C-D-E or A-B-C'-D'-E '.

Grundsätzlich würde sich ein Verbindungselement auch für die einfache elektrische Verbindung mit nur einem Leiter eignen, wobei dann am abstehenden Schaft des Elementes (Kontaktnagel) ein weiterer Leiter angeschlossen werden könnte (z.B. mittels Klemme). Die wichtigste Anwendung dürfte jedoch im Verbinden von Kabeln liegen, wie z.B. in Fig. 1 und 2 gezeigt.Basically, a connecting element would also work for the simple electrical connection with only one conductor is suitable, then on the protruding shaft of the element (contact nail) another conductor could be connected (e.g. using Terminal). However, the most important application is likely to be in connection of cables, e.g. shown in Figs. 1 and 2.
