Moreover, since the partition wall 3p can secure the spatial distance and creepage distance between the busbars 2A and 2B in advance, even if the filling condition of the filler 5 varies, the insulation between the two can be securely secured.
  • the present invention is not limited to this.
  • one lid portion 4c may be provided with one space portion 3v.
  • the present invention is not limited to this, and the lid member 4 may be provided for each of the spaces 3v.
  • thermosetting elastomers or thermoplastic elastomers may be used as long as they satisfy adhesion and followability, and any material called elastic polymer can be used. is.
  • the material constituting the housing 3 is not limited to thermoplastic resin, and thermosetting resin may be used as long as the bus bar 2 is embedded and the material has rigidity as a housing.
  • the space portion 3v is shown as an example in which the space portion 3v is opened vertically so that molding can be performed only by the upper and lower dies, but the space portion 3v is not limited to this.
  • the bus bars 2 may be made of any conductor having excellent conductivity, and the number of bus bars is not limited to two.
  • the plurality of busbars 2 and both ends (ends 2ea, 2eb) of each of the plurality of busbars 2 are exposed, and are spaced apart from each other.
  • the housing 3 is made of a resin and has a space 3v formed with openings through which the intermediate portions 2m of the plurality of bus bars 2 are exposed.
  • a filling material 5 made of elastomer covering the entire circumference of the bus bar 2 at the boundary between and a lid portion 4c that closes the opening and extends toward the filling material 5 from the lid portion 4c and is embedded in the filling material 5 It is configured to include a lid member 4 having an embedded portion 4b.
  • the space 3v is configured to have a second opening on the opposite side of the opening closed by the lid 4c, it becomes possible to perform molding using upper and lower molds without using slide molds.
  • the housing 3 is integrally molded with a plurality of busbars 2, it can be manufactured easily, and in particular, when it has a second opening, it can be manufactured more easily using only upper and lower dies.
  • the embedded portion 4b has a portion whose area in the direction (xy plane direction) perpendicular to the direction (z direction) extending from the lid portion 4c increases toward the distal end away from the lid portion 4c.
  • the filling material 5 is configured so as to cover the entire circumference of the intermediate portion 2m, even if a plurality of busbars 2 are arranged without partitions in the space portion 3v, leakage current between the busbars 2 can be reliably suppressed. can be prevented.
  • a ridge 4r projecting in the thickness direction and a groove 4d recessed in the thickness direction are formed along the entire circumference of the outer edge of the face 4ff facing the opening of the lid 4c.
  • the lid member 4 and the housing 3 are provided with a snap-fit mechanism for forming a snap-fit coupling that regulates movement in the direction of removing the lid member 4 from the housing 3 when the lid portion 4c closes the opening. With this configuration, it is possible to prevent the lid member 4 from falling off from the housing 3 even before the potting material hardens.
  • a male screw 4 cms is formed on the outer peripheral surface of the lid portion 4c, and a female screw 3 fs corresponding to the male screw 4 cms is formed on the inner peripheral surface of the opening of the housing 3. It is possible to prevent the lid member 4 from falling off from the housing 3 even before the potting material hardens.
