Definitions

• the invention relates to an electrical energy distribution system with modular components, which can be contacted at any position of a longitudinal conductor or conductor system by means of a special contact. This applies in particular to single conductors running parallel in the longitudinal direction.
• a system is known from European laid-open specification 0 330 525 which has conductors running in the longitudinal direction inside a metallic sheath. These conductors are provided for different currents, and they have a U-shaped cross section. At regular intervals there is the possibility of inserting junction boxes into prepared openings along the casing. These branches serve e.g. for feeding devices with a lower current. The contact is made by resilient contact terminals with the U-shaped conductors in the channel.
