That is, when the PC32 tube crosses the PC25 tube, the PC32 tube is laid on the upper portion of the junction box 5, and both ends of the PC25 tube are connected to the terminals of the junction box 5 at the crossing points, respectively.

When the first wire tube 11 crosses the third wire tube 13, the first wire tube 11 is laid on the upper portion of the terminal block 5, and both ends of the third wire tube 13 are connected to the connection terminals of the terminal block 5 at the crossing points, respectively.
