  • the extension length of the first connection portion 22 from the first terminal main body 21 of the first terminal fitting 20 and the extension length of the second connection portion 32 from the second terminal main body 31 of the second terminal fitting 30 are It's different.
  • the positioning unit 41 positions the plurality of first terminal fittings 20 and the plurality of second terminal fittings 30 in a state of being alternately aligned so that the first terminal main body 21 and the second terminal main body 31 are lined up in a row. ..
  • the plurality of first connection holes 16 and the plurality of second connection holes 17 are staggered.
  • the holding member is formed with a locking portion for locking the sheet-shaped flexible conductive member, but the holding member may be in a form having no locking portion.
  • a plurality of first terminal fittings and second terminal fittings and a fixing portion between the sheet-shaped flexible conductive member are housed in the housing, but the plurality of first terminal fittings, the second terminal fittings and the sheet are accommodated.
  • the portion fixed to the flexible conductive member may be exposed to the outside of the housing.
  • the first connection portion and the second connection portion formed on the first terminal fitting and the second terminal fitting are passed through the first connection hole and the second connection hole of the sheet-shaped flexible conductive member.
  • the terminal fitting and the second terminal fitting may be fixed in a surface mount form mounted on the surface of the sheet-shaped flexible conductive member.
  • the first connection hole and the second connection hole are arranged in a staggered manner, but the first connection hole and the second connection hole may be arranged so as to be lined up in a row.
