This makes it easier to automate the bolt fastening operation between the first terminal 30 and the second terminal 110.
  • the guide member 140 having the inclined surface 142 is formed as a separate part from the housing body 121. This allows the guide member 140 to be manufactured separately from the housing body 121.
