In the terminal housing member 20, the connecting portion 12 of the bus bar 10 and the connecting portion 32 of the bus bar holding body 30 are both inserted and sandwiched in the slit 25 </ b> A in the above-described housed state. The slit 25B is provided on one outer wall 27 in the arrangement direction of the adjacent shared accommodation space 21A and has a slit 25B communicating with the outside. The slit 25B sandwiches and holds the protruding portion 18 of the bus bar 10 in the accommodated state.

  The bus bar holding body 30 is a holding member that is accommodated in the terminal accommodating member 20 together with the bus bar 10 and holds the bus bar 10 in the terminal accommodating member 20. The bus bar holding body 30 is made of a metal material (for example, copper or copper alloy) having conductivity and high heat dissipation. The bus bar holding body 30 is formed in a shape required by, for example, pressing a metal material formed in a plate shape. As shown in FIG. 4, the bus bar holding body 30 is accommodated in the terminal accommodating member 20 in a state combined with the bus bar 10. As shown in FIG. 6, the bus bar holding body 30 is configured by connecting a plurality of bus bar holding members 31 in a connecting direction (X direction). In the bus bar holding body 30, bus bar holding members 31 adjacent in the connecting direction are connected to each other by a connecting portion 32. The connecting portion 32 is a second connecting portion and is a portion that connects the plate-like portions 34 of the adjacent bus bar holding members 31.

  The bus bar holding member 31 is housed in the terminal housing member 20 together with the bus bar terminal 11 and holds the bus bar terminal 11. The bus bar holding member 31 includes an elastic part 33, a plate-like part 34, a locking hole 35, and a holding part 36.

  The elastic part 33 is formed at the end of the plate-like part 34 in the insertion direction. Of the pair of inner walls 24 that constitute the accommodation space 23 of the terminal accommodating member 20 and oppose each other in the opposing direction (Y direction), the elastic portion 33 is directed from the inner wall 24 on the bus bar holding member 31 side toward the inner wall 24 on the bus bar terminal 11 side. It is a part that elastically deforms in the direction. That is, the elastic portion 33 is elastically deformed in the above-described housing state, thereby pressing the main body portion 14 toward one of the pair of inner walls 24 that constitute the common housing space and oppose each other in the facing direction. Here, the inner wall 24 on the bus bar holding member 31 side is the inner wall on the side where the elastic portion 33 contacts, and the inner wall 24 on the bus bar terminal 11 side is in surface contact with the plate-like portion 34 of the bus bar holding member 31 on the bus bar terminal 11. It is the inner wall of the side to do. When viewed from the connecting direction of the bus bar holding member 31, the elastic portion 33 is formed in a C shape that opens to the extraction direction side, and the opening widens from the bottom in the insertion direction toward the opening direction (extraction direction). Formed as follows. Here, the width between the inner wall 24 on the bus bar holding member 31 side and the inner wall 24 on the bus bar terminal 11 side is L1, and the width in the opposite direction at the opening of the elastic portion 33 in the state where no external force is applied is L2. The plate | board thickness of the main-body part 14 of the bus bar terminal 11 with which the plate-shaped part of the member 31 surface-contacts is set to L3. The elastic part 33 is set so that the width (L2 + L3) obtained by adding the plate thickness L3 to the width L2 satisfies the relationship of width L1 <width (L2 + L3) with respect to the width L1. The elastic portion 33 has a bent portion 33a that extends from the main body portion 14 in the insertion direction and bends in the opposite direction. In the accommodated state, the bent portion 33a holds the bent portion 15 of the bus bar terminal 11 in the insertion direction and holds the bus bar terminal 11 toward the inner wall 24 side.

  The plate-like portion 34 is a portion that extends in the insertion / extraction direction and is in surface contact with the facing direction (here, the Y direction) facing the main body portion 14 in the accommodated state. The plate-like portion 34 is connected to the adjacent plate-like portions by a connecting portion 32.

  The locking hole 35 is a through-hole penetrating in the plate thickness direction (Y direction) of the plate-like portion 34 in the bus bar holding member 31. The locking hole 35 is formed in a predetermined shape by punching or the like, for example. The locking hole 35 is locked to the locking projection 17 on the bus bar terminal 11 side in the above-described accommodated state, and restricts the movement of the bus bar holding member 31 in the removal direction. In accordance with the shape of the locking projection 17 on the bus bar terminal 11 side, the locking hole 35 is formed in a straight line in the direction perpendicular to the insertion direction (here, the X direction). Has been.

  The holding portion 36 is formed at an end portion in the removal direction in the insertion / extraction direction of the plate-like portion 34. The holding part 36 is formed toward one of the Y directions by bending the end part of the plate-like part 34 and bending. The holding portion 36 holds the end portion of the main body portion 14 in the removal direction so as to restrict the movement of the bus bar terminal 11 in the removal direction.

  Next, the assembly procedure of the bus bar holding structure 3 according to the present embodiment will be described. In addition, as an assembly procedure of the bus bar holding structure 3 is not limited to the one described below, the bus bar holding structure 3 may be configured after the assembly. . First, the worker combines the bus bar holder 30 with the bus bar 10. In this case, the worker inserts the locking projection 17 of the main body 14 into the holding portion 36 provided on each bus bar holding member 31 while inserting the end of the main body 14 of each bus bar terminal 11 in the removal direction. The plate-like portion 34 is locked in the locking hole 35. Next, the worker accommodates the assembly (ASS′Y) in which the bus bar 10 and the bus bar holding body 30 are combined in the common accommodation space 21 </ b> A of the terminal accommodation member 20. In this case, the worker inserts the assembly from the opening 22A and pushes it into the shared accommodation space 21A. In the assembly housed in the shared housing space 21A, the elastic portion 33 of the bus bar holding member 31 moves from the inner wall 24 on the bus bar holding member 31 side to the inner wall 24 on the bus bar terminal 11 side of the pair of inner walls 24 facing in the facing direction. Elastically deforms in the direction it heads. Then, the worker inserts the protruding portion 18 of the bus bar 10 into the slit 25B while inserting the portion where the connecting portion 12 of the bus bar terminal 11 and the connecting portion 32 of the bus bar holding member 31 overlap each other into the slit 25A. Next, the worker assembles the connection terminal 120 to the terminal accommodating member 20. In this case, for example, the worker accommodates the connection terminal 120 in the plurality of single accommodation spaces 21 </ b> B (or a part of the plurality of common accommodation spaces 21 </ b> A) of the terminal accommodation member 20. Next, the worker accommodates the corresponding electronic component 2 from the opening 22 of the terminal accommodating member 20. In this case, in the electronic component 2, the bus bar terminal 11 is electrically connected to one terminal 212, and the connection terminal 120 is electrically connected to the other terminal 212. When the bus bar holding structure 3 is the electrical connection box 1 accommodated in the housing 4, the electronic component 2 may be assembled immediately before the electrical connection box 1 is assembled.

  As described above, the bus bar holding structure 3, the electrical junction box 1, and the wire harness WH have the following configurations. That is, the bus bar holding member 31 accommodated in the terminal accommodating member 20 together with the bus bar terminal 11 is in surface contact with the opposite direction facing the bus bar terminal 11 in the accommodated state, and from the inner wall 24 on the bus bar holding member 31 side to the bus bar terminal. It is elastically deformed toward the inner wall 24 on the 11th side. Thereby, since the bus bar holding member 31 holds the bus bar terminal 11 so as to press the bus bar terminal 11 against the inner wall 24 of the terminal accommodating member 20, rattling of the bus bar 10 can be suppressed. Further, since the bus bar holding member 31 is in surface contact with the bus bar terminal 11, heat generated at the bus bar terminal 11 when energized can be transferred to the bus bar holding member 31 side to be dissipated. In addition, since the bus bar holding member 31 has conductivity and is in surface contact with the main body portion 14 of the bus bar terminal 11, the electric resistance of the portion of the main body portion 14 where the horizontal sectional area (X direction and Y direction) is reduced is reduced. It is possible to reduce the heat generated in the bus bar terminal 11.

  Further, the bus bar holding structure 3, the electrical junction box 1, and the wire harness WH are arranged such that the terminal housing member 20 is adjacent to the shared housing space 21 </ b> A provided corresponding to the bus bar terminals 11. A slit 25A that communicates the inner wall 24 between 21A is provided. As a result, both the bus bar 10 and the bus bar holding body 30 are inserted and held in the slit 25A in the accommodated state, and the bus bar 10 and the bus bar holding body 30 are prevented from rattling, and the bus bar 10 and the bus bar holding body 30 are connected to the counterpart terminal.

As a result, the bus bar holding member 31 restricts the movement of the bus bar terminal 11 in the removal direction and the bus bar terminal 11 restricts the movement of the bus bar holding member 31 in the removal direction, so that the bus bar terminal 11 and the bus bar holding member 31 are not dropped. Can be prevented.

  Further, in the bus bar holding structure 3, the electrical junction box 1, and the wire harness WH, since the bus bar terminal 11 has the bent portion 15 and the locked portion 16, the bus bar terminal 11 can be changed without changing the shape of the common accommodation space 21A. The terminal 11 can be accommodated and held in the shared accommodation space 21A.

  The bus bar holding structure 3, the electrical junction box 1, and the wire harness WH are formed such that the plurality of shared accommodation spaces 21 </ b> A extend longer than the plurality of single accommodation spaces 21 </ b> B in the insertion / extraction direction of the bus bar terminal 11. Yes. As a result, the difference between the shared accommodation space 21A and the single accommodation space 21B can be easily confirmed visually, and assembly errors of the connection terminal 120 and the bus bar 10 during assembly work can be reduced.

As shown in FIG. 27, the extending portion 19B contacts the inner wall 24b facing the main body portion 14B in the facing direction in the accommodated state where the bus bar terminal 11Bb is accommodated in the shared accommodating space 21A. In other words, the elastic portion 133B is elastically deformed in a state where the bus bar terminal 11Ba is accommodated together with the heat radiating member 40 in the common accommodating space 21A, and thereby moves from the inner wall 24a on the heat radiating member 40 side to the inner wall 24b on the extending portion 19B side. The extending part 19B is pressed in the direction.

  As shown in FIG. 22, the heat radiating member 40 is accommodated in the shared accommodating space 21A in a state combined with the bus bar 10C. The heat dissipating member 40 is in close contact with the bus bar 10C and is accommodated in the shared accommodating space 21A, and transmits heat generated by the bus bar 10C to be released to the outside. The heat radiating member 40 is formed into a shape required by, for example, pressing a plate-shaped metal material (for example, copper or copper alloy) having high heat dissipation. As shown in FIG. 6, the heat dissipating member holding body 30 is configured by connecting a plurality of bus bar holding members 31 in a connecting direction (X direction). In the bus bar holding body 30, bus bar holding members 31 adjacent in the connecting direction are connected to each other by a connecting portion 32. The connecting portion 32 is a second connecting portion and is a portion that connects the plate-like portions 34 of the adjacent bus bar holding members 31.

  As described above, the heat radiating member 40 is formed to extend in the insertion / extraction direction, and the main body portion 14B and the extending portion 19A are disposed in the accommodated state where the heat radiating member 40 is accommodated in the common accommodating space 21A together with the bus bar terminals 11Ba and 11Bb. And is in surface contact with the main body 14B in the opposing direction. Thereby, since the heat generated in the bus bar 10C is transmitted to the heat radiating member 40, the generated heat can be dispersed and radiated to the outside.
