Abstract

A connector for connecting two conductor rail sections, the connector having an electrical conductor that is fastened at each end to the conductor rails. A central region of the conductor is fastened to a connection element. The connection element is slidingly connected to both of the two conductor rails. The electrical conductor has two flexible, undulating portions. These are located between the central region of the electrical conductor and each of its two, attached ends, and serve to compensate for the expansion and contraction of the two conductor rails with changes in temperature.
