The tube has front contact plates (11, 21) with central and circumferential contact units electrically connected with central and circumferential connection plates (161, 162) of a back contact plate (15) by wires (14) in tube segments (1, 2), respectively. A flexible side piece (17) of the segments is extended into an accommodation chamber of the adjacent tube segments and is pressed against side walls of the tube segment. The plates (161, 162) are connected with the central and circumferential contact units, respectively, at the front contact plates. |
