| 摘要 |
<p>The present invention relates to a mechanical arrangement, adapted to be able to extend along a selected stretch of road and its assigned series-oriented road sections (2a1, 2a2) and intended to be able to receive a vehicle-related current-collecting means, comprising one or more elongate track or gaps (51, 52) assigned to each road section and having inserted current-feedable and energizable electrical conductors (4a, 4b), the electrical conductors comprising at least two essentially similar rail sections (4a1, 4a2) connectable with each other in the longitudinal direction of the track. In its longitudinal end portion (401), the first rail section comprises a first contact structure (403), and in its end portion (402) facing one end portion of the first rail section, the second rail section comprises a second contact structure (404) corresponding to the first contact structure, at least a part of the first contact structure being adapted to be received in a cavity in the second contact structure in order to, via said first and second contact structures, allow a relative movement in the longitudinal direction of the rail sections caused by a temperature difference, the first and second contact structures corresponding to each other being adapted to co-operate electrically and mechanically, allowing a transfer of an electric current and voltage between the first rail section and the second rail section.</p> |
