Abstract

The electrical cable for vehicle wiring has alternate round or flat configurations. This is obtained by arranging the cable conductors in a circle and providing a longitudinal separation line (Fig. D) in the cable insulation between 2 of these conductors (Fig. A) allowing the cable to be opened out, so that the conductors lie next to one another in a common plane. The separation line (Fig. D) is provided by a notch in the cable insulation reducing its wall thickness. The notch location is indicated by a colour coding. Alternatively it may be provided by spaced perforations extending in a line along the cable insulation. ADVANTAGE - Combines advantages of round and ribbon cables.

Description

Meine Erfindung hat den Zweck, die diversen Probleme der Flachkabel zu lösen.My invention has the purpose of addressing the various problems of flat cables to solve.

Definition of flat cable

Ein Flachkabel zum Leiten von elektrischem Strom besteht aus der Isolierung (Fig. 1) und den Leitern (Fig. 2).A flat cable for conducting electrical current consists of the insulation ( Fig. 1) and the conductors ( Fig. 2).

Es ist dadurch gekennzeichnet, daß die Breite b größer als die Dicke d ist.It is characterized in that the width b is larger than the thickness d.

Advantages of flat cables

- Fig. 3: The individual conductors are unmistakably defined in their order.
- Fig. 4: Small bending radii are possible compared to the round cable.
- Flat cables can be cut using the insulation displacement technology Connect plugs.
For this purpose, the flat cable is placed between the connector housing ( Fig. 6) and the cover ( Fig. 5). When pressing down the cover ( Fig. 5) zer cut the contact pins ( Fig. 7) the insulation ( Fig. 8) and make the connection by clamping the conductor ( Fig. 9).

Disadvantages of flat cables

- Fig. 10: If the bending plane is not parallel to the line of symmetry running through all conductors, the required bending radius increases. This leads to poor installation z. B. construction in the vehicle.
- If a cable is led through the hole in a narrow wall ( Fig. 12), special seals ( Fig. 11) are required to prevent water and dirt from entering.
Due to the non-circular contour of the flat cable, this type of Sealing complex and unsafe.
- Flat cables cannot be laid with elements suitable for round cables ( Fig. 13).

Eliminate the disadvantages Flat / round cable according to drawing

Dieses Kabel besteht aus den Leitern (Fig. A) zum Leiten von elektrischem Strom, der Isolierung (Fig. B), einem Hohlraum (Fig. C) und einer längs des Kabels verlaufenden Sollbruchlinie (Fig. D).This cable consists of the conductors ( Fig. A) for conducting electrical current, the insulation ( Fig. B), a cavity ( Fig. C) and a predetermined breaking line running along the cable ( Fig. D).

Die Anzahl der Leiter ist variabel, im Beispiel sind vier dargestellt. Dieses Flach/Rundkabel läßt sich wie ein herkömmliches Rundkabel verlegen.The number of conductors is variable, four are shown in the example. This flat / round cable can be laid like a conventional round cable.

Zum Verbinden mit einem Schneid-Klemm-Stecker wird das Kabel im Stecker bereich entlang der Sollbruchlinie (Fig. D) geöffnet und ausgebreitet (Fig. J und P). Ausführung der Sollbruchlinie nach Einzelheit Z 1-4.To connect with an insulation displacement connector, the cable in the connector area is opened and spread out along the predetermined breaking line ( Fig. D) ( Fig. J and P). Execution of the predetermined breaking line according to detail Z 1-4.

Im folgenden ein Anwendungsbeispiel:In the following an application example:

Das Flach-Rundkabel (Fig. L) ist mit zwei Steckern versehen, ein Stecker am Kabelende und der andere davor. Zum Anschließen muß das Kabel nicht getrennt werden und kann in Reihenschaltung von einem Verbraucher zum anderen verlegt werden.The flat round cable ( Fig. L) is provided with two plugs, one plug at the end of the cable and the other in front. The cable does not have to be disconnected for connection and can be laid in series from one consumer to another.

Da das Kabel nur im Steckerbereich abgeflacht ist, hat es bei Verlegen einen in alle Richtungen gleichen Biegeradius.Since the cable is only flattened in the connector area, it has to be laid when laying a bending radius that is the same in all directions.

Beim Durchlaufen von Trennwänden (Fig. M) können für das Flach/Rundkabel handelsübliche Kabeltüllen (Fig. O) verwendet werden.When passing through partition walls ( Fig. M), standard cable grommets ( Fig. O) can be used for the flat / round cable.

Zum Befestigen eignen sich handelsübliche Befestigungselemente (Fig. N).Standard fastening elements ( Fig. N) are suitable for fastening.
