PURPOSE:To facilitate the connection of a ground coil for a magnetically floating railway by providing an internal conductor slidably contacted, insulating the outer perphery of the conductor with molding resin and employing an insulating bus provided with a grounding layer on the outer peripheral surface. CONSTITUTION:A conductor 2 of a ground coil 1 is electrically connected to a conductor 12 of an insulated bus 11 via slidably contacting connector 13, e.g., tulip connector or the like, and the outermost ground layer 7 is connected via a metallic ring and bolt 14. The bus 11 consists of an internal conductor 12 and molding resin 15, and the layer 7, and is connected to the conductor 4 of a cable 3 with a wedge 16 urged by a clamp 17. A premolding insulator 18 is provided between the bus 11 and the cable 3, and is urged by a bracket 19. The ground terminal 9 of the cable 3 is connected to a protection bracket 21 via a grounding wire 20, and is connected to the layer 7 of the bus 11 via bolt 22. According to this construction, since the insulating layer is formed of resin, it can be increased in its withstand voltage, it is not necessary to bent it with a large radius, it can be reduced in size, and can be detachable with bolt clamping type. |
