    摘要: An electrical connection line (L) for an electrical unit of a motor vehicle, which electrical connection line serves to electrically connect the unit to an electrical power source which is arranged in the motor vehicle and/or to another electrical unit. The connection line (L) is designed as a three-phase line with three insulated electrical conductors (1, 2, 3), of which each has an electrical individual sheath (5) which is in contact with its insulation means (4) and is closed all the way around. An electrical outer sheath (7) which surrounds the three sheathed conductors (1, 2, 3) and is closed all the way around is also provided and a coupling element which is equipped with electrical contacts which are insulated from one another is fitted at least to one end of the connection line (L) in a moisture-tight manner, and the electrical conductors (1, 2, 3), their individual sheaths (5) and the outer sheath (7) are electrically conductively connected to the contacts of the said coupling element.
