  • the short-circuit plate 42 and the insulating plate 47 are formed with the mis-assembly prevention protrusion 49 and the mis-assembly prevention recess 43 that can be fitted only when the assembly is in an appropriate assembly form. 47 can be prevented from being assembled in an unauthorized form.
  • ⁇ Other embodiments> The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.
  • a plurality of short-circuit plates are stacked via insulating plates (insulation members), but the plurality of short-circuit members may be arranged so as to be spaced apart from each other.
  • the insulating plate (insulating member) is provided with a guide hole corresponding to the non-contact hole and having an opening area smaller than the non-contact hole.
  • the insulating plate has such a guide hole. It may be a form that does not.
  • the short circuit plate (short circuit member) and the insulation plate (insulation member) were assembled
  • the short-circuit plate (short-circuit member) and the insulation plate (insulation member) are formed with the wrong assembly prevention portion (the wrong assembly prevention recess and the wrong assembly prevention projection). The form which does not form a prevention part may be sufficient.
  • one short-circuit plate (short-circuit member) is attached to one insulation plate (insulation member), but a plurality of short-circuit plates may be attached to one insulation plate.
  • one short-circuit plate may be attached to each of the front and back surfaces of the insulating plate, or a plurality of short-circuit plates may be attached to the front surface of the insulating plate in a non-contact state.
  • the opening shape of the conduction hole is an H shape, but the opening shape of the conduction hole may be an I shape (slit shape), a concave shape, or the like.
  • the joint connector and the terminal fitting have a function for relaying the wire harness and a function for branching the wire harness. The present invention can also be applied to the case where one or both of the relay function and the branch function are not provided.
