Abstract

An electrical line ( 5 ) for electrically conductively connecting two units arranged in a motor vehicle, where the units have insulated electrical conductors surrounded by a common electrically effective screen. Over the entire length of the line ( 5 ) the construction of the line includes at least one light conductor ( 10 ) which is connected in the operating position to an evaluating unit ( 12 ) coupled to a switching element ( 11 ), and is integrated in the screen ( 9 ) of the line ( 5 ), or is arranged directly underneath the screen ( 9 ) of the line ( 5 ) while being in contact with the line ( 5 ), so that damage to the line ( 5 ) leads with certainty at least to a deformation of the light conductor ( 10 ) which leads to a signal which can be recognized by the evaluating unit ( 12 ).

First claim

The invention claimed is:

1. An electrical line for electrically conductively connecting two units arranged in a motor vehicle, said electrical line comprising:
at least one electrical conductor;
an electrically conductive screen surrounding said least one electrical conductor; and
at least one light conductor, said light conductor is either one of integrated in said electrically conductive screen or positioned directly underneath and in contact with said electrically conductive screen, said at least one light conductor extending over the entire length of said electrical line,
wherein said light conductor is connected to an evaluating unit,
wherein said electrically conductive screen and said light conductor are arranged together in a manner that deformation of said screen simultaneously deforms said light conductor, the deformation of said light conductor being detectable at said evaluating unit as a signal change within said light conductor, and
wherein said evaluating unit is connected to a switching element, said switching unit configured to disconnect said electrical line from power in the event said evaluating unit detects a signal change within said light conductor.
