Description

GERMAN

The invention relates to a cable lug for a carbon core cable with a thermoplastic Material existing coat. As tests have shown, such cables are special Suitable for compensating radio reception interference caused by the ignition sparks of motor vehicles caused.

The ignition of engines for motorcycles and especially mopeds is particularly important for radio reception very annoying. It has been found that when using a carbon core cable for these vehicles such a disturbance can be avoided. The difficulty, however, is this cable with one to provide good, connectable termination.

Cable lugs for ignition cables with metallic conductors have become known that are used to make contact have a mandrel that penetrates the metal strand serving as a conductor. The cable sheath is used in the known cable lugs held in an opening with a matching diameter or by bending them together clamped in a sheet metal sleeve.

These known cable lugs do not exclude a slight displacement of the dome to the metal conductor, what is not a disadvantage with metal conductors. When using carbon core cables, however, a slight movement between the mandrel and the carbon core interrupted the contact. That's why the known versions of cable lugs are unsuitable for this.

To this end, the invention proposes a novel end connection for this particular type of Cables in front. It is a known cable lug used, which consists of a metal cap with a within the same lying and with this attached, pointed metal mandrel. According to the invention, the mandrel is almost completely surrounded by a thermoplastic jacket, on the one hand the cap fills and on the other hand is expanded like a sleeve. The sleeve-like part is over the Sheath of the cable pushed and welded to this.

In the drawing, an embodiment of the invention is shown, namely the invention End connection shown in cross section.

1 with the jacket of a cable is referred to, within which insulating material 2 is located. Of the The core of the cable is made of carbon. The end connection is formed by a jacket 4, which with a extended part 5 is provided. At the top there is a metal cap 7 with one on the same attached, pointed mandrel 6, which is also of conductive material, e.g. B. metal, and is attached to the cap. When fastening the connection on the cable, the cable jacket 1 is in the
