  In the above description, the divided block aggregate 6 has a total of four divided blocks 7A, divided blocks 7B, divided blocks 7C, and divided blocks 7D, one by one, as a plurality of divided blocks 7. However, the present invention is not limited to this. In the divided block aggregate 6, all of the plurality of divided blocks 7 may have the same shape. The divided block aggregate 6 may be constituted by two divided blocks 7 or may be constituted by three divided blocks 7. Furthermore, the divided block aggregate 6 may include five or more divided blocks 7.

  At least one of the locking portions 72 and 74 included in each divided block 7 described above is locked to the bus bar 5 in the divided block assembly 6 so that the bus bar 5 and the divided block assembly 6 do not fall off. It is sufficient that all of them are not locked to the bus bar 5.
