ところで、従来のバスバ連結構造においては、連結体の弾性変形に伴う反力を保持力として利用して、相手方のバスバの被連結体を挟み込む。このため、従来のバスバ連結構造は、被連結体の板厚に公差程度の誤差が生じていたとしても、この被連結体に対する保持力を複数の連結体で発生させることができる。しかしながら、従来のバスバ連結構造においては、公差程度の誤差では済まないくらい板厚の厚いバスバが相手方に用いられてしまうと、この厚みの増した被連結体に対する保持力を複数の連結体で発生させることができなくなる可能性がある。 By the way, in the conventional busbar connection structure, the reaction force due to the elastic deformation of the connecting body is used as a holding force to sandwich the connected body of the mating busbar. Therefore, in the conventional busbar connection structure, even if there is an error of the tolerance level in the plate thickness of the connected body, the plurality of connected bodies can generate a holding force for the connected body. However, in the conventional busbar connection structure, if a busbar having a thickness that is too thick to be satisfied with the tolerance is used as the mating member, a plurality of connecting members generate a holding force for the thicker connected member. may become impossible.

［実施形態］
本発明に係るバスバ連結構造及び連結バスバの実施形態の１つを図１から図９に基づいて説明する。 [Embodiment]
One embodiment of the busbar connection structure and the connection busbar according to the present invention will be described with reference to FIGS. 1 to 9. FIG.

図１から図６の符号１は、本実施形態の連結バスバを示す。その連結バスバ１は、複数の接続対象物（図示略）の間を電気的に接続させるものであり、例えば、電気接続箱等における絶縁性の筐体（図示略）の中に収容される。尚、接続対象物とは、例えば、リレーや回路保護部品等の電子部品、回転機等の負荷、二次電池等の電源などのことをいう。 Reference numeral 1 in FIGS. 1 to 6 indicates the connection bus bar of this embodiment. The connection bus bar 1 electrically connects a plurality of connection objects (not shown), and is housed in an insulating housing (not shown) such as an electric connection box, for example. The objects to be connected include, for example, electronic components such as relays and circuit protection components, loads such as rotating machines, power sources such as secondary batteries, and the like.

具体的に、本実施形態の連結バスバ１は、導電性の第１バスバ１０と第２バスバ２０とを備え、これらが連結構造（バスバ連結構造）３０を介して一体化されたものである（図１から図６）。 Specifically, the connection bus bar 1 of the present embodiment includes a conductive first bus bar 10 and a second bus bar 20, which are integrated via a connection structure (bus bar connection structure) 30 ( 1 to 6).

第１バスバ１０と第２バスバ２０は、金属等の導電性材料で成形される。この例示の第１バスバ１０と第２バスバ２０は、母材となる金属板に打ち抜き加工や折り曲げ加工等を施して成形される。第１バスバ１０については、後述するように一部に弾性を持たせるので、導電率が高く且つ第２バスバ２０よりも高弾性の金属板（例えば、銅合金を原材料とするもの）で成形する。一方、第２バスバ２０については、導電率が高く且つ原価の低い金属板（例えば、銅を原材料とするもの）で成形する。 The first bus bar 10 and the second bus bar 20 are made of a conductive material such as metal. The illustrated first bus bar 10 and second bus bar 20 are formed by punching, bending, or the like from a metal plate serving as a base material. Since the first bus bar 10 is partially elastic as will be described later, it is formed of a metal plate (for example, made of copper alloy as a raw material) having high conductivity and higher elasticity than the second bus bar 20. . On the other hand, the second bus bar 20 is made of a metal plate (for example, made of copper as a raw material) with high conductivity and low cost.

この例示の第１バスバ１０は、平板状の主体１１と、複数の電気接続体１２と、を有する（図１から図４）。主体１１は、矩形に形成されている。電気接続体１２は、電子部品の電気接続体（図示略）との間で物理的且つ電気的に接続されるものであり、接続端子としての機能を成す。この例示の電気接続体１２は、電子部品の電気接続体たる雄タブ状の相手方端子が挿入嵌合される音叉端子として形成されている。この電気接続体１２は、主体１１の短手方向における一方の端部１１ａの端面から同一の平面上で主体１１の短手方向に沿って突出させている。それぞれの電気接続体１２は、主体１１の長手方向に沿って互いに間隔を空けて直列配置されている。 The illustrated first bus bar 10 has a flat main body 11 and a plurality of electrical connectors 12 (FIGS. 1 to 4). The main body 11 is formed in a rectangular shape. The electrical connector 12 is physically and electrically connected to an electrical connector (not shown) of an electronic component, and functions as a connection terminal. The illustrated electrical connector 12 is formed as a tuning fork terminal into which a male tab-like mating terminal, which is an electrical connector of an electronic component, is inserted and fitted. The electrical connector 12 protrudes along the width direction of the main body 11 on the same plane from the end face of one end portion 11a of the main body 11 in the width direction. Each electrical connector 12 is arranged in series with a space therebetween along the longitudinal direction of the main body 11 .

この例示の第２バスバ２０は、平板状の主体２１と、片体状の電気接続体２２と、を有する（図１から図４）。主体２１は、矩形に形成されている。電気接続体２２は、雄タブ状に形成されており、例えば、電源側の雌端子（図示略）が嵌合接続される。この電気接続体２２は、主体１１の短手方向における一方の端部２１ａの端面から同一の平面上で主体２１の短手方向に沿って突出させている。それぞれの電気接続体２２は、主体２１の長手方向に沿って互いに間隔を空けて直列配置されている。 The illustrated second bus bar 20 has a flat main body 21 and a piece-shaped electrical connector 22 (FIGS. 1 to 4). The main body 21 is formed in a rectangular shape. The electrical connector 22 is formed in the shape of a male tab, and for example, a female terminal (not shown) on the power supply side is fitted and connected. The electrical connector 22 protrudes along the width direction of the main body 21 on the same plane from the end surface of one end 21a of the main body 11 in the width direction. Each electrical connector 22 is arranged in series with a space therebetween along the longitudinal direction of the main body 21 .

第１バスバ１０と第２バスバ２０は、それぞれの電気接続体１２とそれぞれの電気接続体２２の突出方向を同じ向きに合わせた状態で、バスバ連結構造３０によって連結される。そのバスバ連結構造３０は、第１バスバ１０に設けた第１から第３の連結体１３Ａ－１３Ｃと、第２バスバ２０に設けた被連結体２３と、を備える（図１から図４）。 The first bus bar 10 and the second bus bar 20 are connected by the bus bar connection structure 30 with the projecting directions of the respective electrical connection bodies 12 and the respective electrical connection bodies 22 aligned in the same direction. The busbar connection structure 30 includes first to third connection bodies 13A to 13C provided on the first busbar 10 and a connected body 23 provided on the second busbar 20 (FIGS. 1 to 4).

第１から第３の連結体１３Ａ－１３Ｃは、図７から図９に示す基準バスバ５００の被連結体（以下、「基準被連結体」という。）５１０に連結させるべく形成される。その基準被連結体５１０は、平行な第１基準平面５１１及び第２基準平面５１２を有する平板状に形成されている。第１から第３の連結体１３Ａ－１３Ｃは、後述するように、その第１基準平面５１１及び第２基準平面５１２の間隔（つまり、基準被連結体５１０の板厚）よりも板厚の厚い第２バスバ２０にも連結させる（図１から図６）。 The first to third connecting bodies 13A-13C are formed to be connected to a connected body (hereinafter referred to as a "reference connected body") 510 of the reference bus bar 500 shown in FIGS. The reference connected body 510 is formed in a flat plate shape having a first reference plane 511 and a second reference plane 512 parallel to each other. As will be described later, the first to third connecting bodies 13A to 13C are thicker than the interval between the first reference plane 511 and the second reference plane 512 (that is, the thickness of the reference connected body 510). It is also connected to the second bus bar 20 (FIGS. 1 to 6).

第１から第３の連結体１３Ａ－１３Ｃは、互いに間隔を空けた直列配置状態で第１バスバ１０に設けられる（図１から図４、図７及び図８）。この例示の第１から第３の連結体１３Ａ－１３Ｃは、主体１１の短手方向における他方の端部１１ｂの端面から主体１１の短手方向に沿って電気接続体１２とは逆向きに突出させている。つまり、この第１から第３の連結体１３Ａ－１３Ｃは、第１バスバ１０の主体１１から各々同一方向に突出させることで延在させている。 The first through third links 13A-13C are provided on the first busbar 10 in a spaced-apart series arrangement (FIGS. 1-4, 7 and 8). The illustrated first to third connecting bodies 13A to 13C protrude from the end surface of the other end portion 11b in the short direction of the main body 11 along the short direction of the main body 11 in the direction opposite to the electrical connector 12. I am letting In other words, the first to third connecting bodies 13A to 13C extend by protruding in the same direction from the main body 11 of the first bus bar 10 respectively.

第１から第３の連結体１３Ａ－１３Ｃは、その延在方向に沿って第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間に基準被連結体５１０を嵌入させるものとして形成される。つまり、第１から第３の連結体１３Ａ－１３Ｃは、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間に基準被連結体５１０を挟み込み、その基準被連結体５１０の第１基準平面５１１と第２基準平面５１２との間に挟持力を作用させることによって、第２バスバ２０に連結させる。 The first to third connecting bodies 13A to 13C have a reference connecting body 510 inserted between the first connecting body 13A and the second connecting body 13B and the third connecting body 13C along their extending directions. formed as That is, the first to third connecting bodies 13A to 13C sandwich the reference connected body 510 between the first connecting body 13A and the second connecting body 13B and the third connecting body 13C, and the reference connected body 510 By applying a clamping force between the first reference plane 511 and the second reference plane 512 , the second bus bar 20 is connected.

そこで、第１から第３の連結体１３Ａ－１３Ｃについては、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間への基準被連結体５１０の挿入と挟み込みを可能にするべく、それぞれを主体１１の他方の端部１１ｂ側が固定端となる片持ち形状に形成し、かつ、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの内の少なくとも一方を主体１１の平面１１ｃ，１１ｄに対する直交方向にオフセットさせる（図３及び図４）。更に、第１から第３の連結体１３Ａ－１３Ｃについては、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間で基準被連結体５１０に挟持力を作用させるべく、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの内の少なくとも一方を基準被連結体５１０に対する挟持方向に弾性変形し得るものとして形成する。 Therefore, for the first to third connecting bodies 13A to 13C, it is possible to insert and sandwich the reference connected body 510 between the first connecting body 13A and the second connecting body 13B and the third connecting body 13C. In order to do so, each is formed in a cantilever shape with the other end 11b side of the main body 11 serving as a fixed end, and at least one of the first connecting body 13A, the second connecting body 13B, and the third connecting body 13C are offset perpendicularly to the planes 11c and 11d of the main body 11 (FIGS. 3 and 4). Furthermore, for the first to third connecting bodies 13A to 13C, in order to apply a clamping force to the reference connected body 510 between the first connecting body 13A, the second connecting body 13B, and the third connecting body 13C, At least one of the first connecting body 13A, the second connecting body 13B, and the third connecting body 13C is formed to be elastically deformable in the clamping direction with respect to the reference connected body 510 .

第１連結体１３Ａは、第１基準平面５１１に対して押圧力を作用させる第１押圧部１３ａを有する（図３）。また、第２連結体１３Ｂは、第１基準平面５１１に対して第１押圧部１３ａと同じ向きに押圧力を作用させる第２押圧部１３ｂを有する（図３、図５、図６及び図９）。また、第３連結体１３Ｃは、第１押圧部１３ａと第２押圧部１３ｂとの間で、第２基準平面５１２に対して第１押圧部１３ａ及び第２押圧部１３ｂとは逆向きに押圧力を作用させる第３押圧部１３ｃを有する（図４、図５、図６及び図９）。この例示では、第３連結体１３Ｃを主体１１の平面１１ｃ，１１ｄに対する直交方向にオフセットさせ且つ弾性変形し得るものとして形成している（図１から図９）。 13 A of 1st connection bodies have the 1st press part 13a which makes press force act on the 1st reference plane 511 (FIG. 3). In addition, the second connecting body 13B has a second pressing portion 13b that applies a pressing force in the same direction as the first pressing portion 13a to the first reference plane 511 (FIGS. 3, 5, 6 and 9). ). Further, the third connecting body 13C is pressed between the first pressing portion 13a and the second pressing portion 13b with respect to the second reference plane 512 in the opposite direction to the first pressing portion 13a and the second pressing portion 13b. It has a third pressing portion 13c for applying pressure (FIGS. 4, 5, 6 and 9). In this example, the third connecting body 13C is offset in the direction perpendicular to the planes 11c and 11d of the main body 11 and is elastically deformable (FIGS. 1 to 9).

この例示の第１連結体１３Ａと第２連結体１３Ｂは、各々、主体１１と同一の平面１１ｃ，１１ｄ上で矩形の片体状に形成されている（図３及び図４）。つまり、第１連結体１３Ａと第２連結体１３Ｂは、各々、一方の平面が主体１１の一方の平面１１ｃと面一になっており、他方の平面が主体１１の他方の平面１１ｄと面一になっている。第１連結体１３Ａにおいては、その一方の平面が第１押圧部１３ａとして利用される。また、第２連結体１３Ｂにおいては、その一方の平面が第２押圧部１３ｂとして利用される。 The illustrated first connecting body 13A and second connecting body 13B are each formed in a rectangular piece shape on the same planes 11c and 11d as the main body 11 (FIGS. 3 and 4). That is, each of the first connecting body 13A and the second connecting body 13B has one plane flush with one plane 11c of the main body 11 and the other plane flush with the other plane 11d of the main body 11. It has become. One plane of the first connecting body 13A is used as the first pressing portion 13a. In addition, one plane of the second connecting body 13B is used as the second pressing portion 13b.

一方、この例示の第３連結体１３Ｃは、主体１１の他方の端部１１ｂの端面から主体１１の短手方向における電気接続体１２とは逆向きに突出させた突出部１３Ｃ1と、この突出部１３Ｃ1における突出方向側の端部から一方の平面１１ｃ側に折り曲げられたオフセット部１３Ｃ2と、を有する（図３及び図６）。更に、この例示の第３連結体１３Ｃは、その折り曲げられた先のオフセット部１３Ｃ2の端部から他方の平面１１ｄ側に折り返された折り返し部１３Ｃ3と、その折り返された先の折り返し部１３Ｃ3の端部から一方の平面１１ｃ側に折り曲げられた拾い部１３Ｃ4と、を有する（図３及び図６）。 On the other hand, the illustrated third connecting body 13C includes a projecting portion 13C 1 projecting from the end surface of the other end portion 11b of the main body 11 in the direction opposite to the electrical connecting body 12 in the lateral direction of the main body 11, and the projecting portion 13C 1 . and an offset portion 13C2 that is bent from the end of the portion 13C1 on the protruding direction side toward the one plane 11c (FIGS . 3 and 6). Further, the illustrated third connecting body 13C includes a folded portion 13C3 folded back from the end of the folded offset portion 13C2 toward the other plane 11d, and a folded portion 13C 3 and a pickup portion 13C4 bent toward one plane 11c (FIGS. 3 and 6).

この例示の第３連結体１３Ｃにおいては、突出部１３Ｃ1とオフセット部１３Ｃ2と折り返し部１３Ｃ3と拾い部１３Ｃ4とが各々矩形の片体状に形成されている。また、この例示の第３連結体１３Ｃにおいては、折り返し部１３Ｃ3における第１連結体１３Ａ側及び第２連結体１３Ｂ側の平面が第３押圧部１３ｃとして利用される。よって、オフセット部１３Ｃ2は、嵌入されてきた基準被連結体５１０をその嵌入方向で係止させる係止部として利用することができる。また、拾い部１３Ｃ4は、嵌入させる基準被連結体５１０を第１から第３の押圧部１３ａ－１３ｃに向けて誘い込むための部位として利用される。 In the illustrated third connecting body 13C, the protruding portion 13C1 , the offset portion 13C2 , the folded portion 13C3 , and the pick-up portion 13C4 are each formed in a rectangular piece shape. Further, in the illustrated third connecting body 13C, the flat surfaces of the folded portion 13C3 on the first connecting body 13A side and the second connecting body 13B side are used as the third pressing portion 13c. Therefore, the offset portion 13C2 can be used as a locking portion that locks the inserted reference connected body 510 in its insertion direction. Further, the pick-up portion 13C 4 is used as a portion for guiding the reference connected body 510 to be fitted toward the first to third pressing portions 13a to 13c.

第１から第３の連結体１３Ａ－１３Ｃにおいては、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間に基準被連結体５１０を嵌入させていくことによって、その基準被連結体５１０に第３連結体１３Ｃの自由端側（つまり、拾い部１３Ｃ4側）が押し動かされ、その第３連結体１３Ｃの固定端側（つまり、突出部１３Ｃ1側及びオフセット部１３Ｃ2側）が弾性変形させられる。この第１から第３の連結体１３Ａ－１３Ｃにおいては、基準被連結体５１０の嵌入が完了すると、第１押圧部１３ａ及び第２押圧部１３ｂから第１基準平面５１１に各々押圧力を作用させ、かつ、第３押圧部１３ｃから第２基準平面５１２に押圧力を作用させた状態となる。よって、第１から第３の連結体１３Ａ－１３Ｃは、基準被連結体５１０に対して保持力（以下、「要求保持力」という。）を作用させ続けることができるので、この基準被連結体５１０に対する連結状態を保つことができる。従って、第１から第３の連結体１３Ａ－１３Ｃは、第１バスバ１０を基準バスバ５００に連結させ、その連結状態を維持させることができる。 In the first to third connecting bodies 13A to 13C, by inserting the reference connected body 510 between the first connecting body 13A and the second connecting body 13B and the third connecting body 13C, the reference The free end side of the third connecting body 13C (that is, the pickup portion 13C4 side) is pushed by the connected body 510, and the fixed end side of the third connecting body 13C (that is, the projecting portion 13C1 side and the offset portion 13C) is pushed. 2 side) is elastically deformed. In the first to third connecting bodies 13A to 13C, when the insertion of the reference connected body 510 is completed, a pressing force is applied to the first reference plane 511 from the first pressing portion 13a and the second pressing portion 13b. In addition, a state is created in which a pressing force is applied to the second reference plane 512 from the third pressing portion 13c. Therefore, since the first to third connecting bodies 13A to 13C can continue to exert a holding force (hereinafter referred to as "required holding force") on the reference connecting body 510, this reference connecting body 510 can remain connected. Therefore, the first to third connecting bodies 13A-13C can connect the first bus bar 10 to the reference bus bar 500 and maintain the connected state.

要求保持力とは、第１から第３の連結体１３Ａ－１３Ｃと基準被連結体５１０との間の連結状態を保ち続けることが可能な大きさの保持力のことであり、設計上の要求値として定められたもののことである。また、第１から第３の連結体１３Ａ－１３Ｃと基準被連結体５１０との間においては、第１押圧部１３ａと第１基準平面５１１とを面接触させ、かつ、第２押圧部１３ｂと第１基準平面５１１とを面接触させ、かつ、第３押圧部１３ｃと第２基準平面５１２とを面接触させることが望ましい。 The required holding force is a holding force of a magnitude that allows the first to third connecting bodies 13A-13C and the reference connected body 510 to maintain the connected state, and is a design requirement. It is defined as a value. Further, between the first to third connecting bodies 13A to 13C and the reference connected body 510, the first pressing portion 13a and the first reference plane 511 are in surface contact, and the second pressing portion 13b and the second pressing portion 13b are in contact with each other. It is desirable to bring the first reference plane 511 into surface contact and bring the third pressing portion 13c into surface contact with the second reference plane 512 .

このように形成された第１から第３の連結体１３Ａ－１３Ｃは、第１基準平面５１１及び第２基準平面５１２の間隔（つまり、基準被連結体５１０の板厚）よりも板厚の厚い第２バスバ２０にも連結させる（図１から図６）。第２バスバ２０においては、主体２１が第１基準平面５１１及び第２基準平面５１２の間隔（基準被連結体５１０の板厚）よりも厚い板厚に形成されている。その主体２１の板厚とは、例えば、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間に嵌入させることが不可能な厚さのことである。また、この主体２１の板厚とは、例えば、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間への嵌入が可能であったとしても、第１から第３の連結体１３Ａ－１３Ｃから主体２１に対して要求保持力を作用させることが不可能な厚さのことである。また、この主体２１の板厚とは、例えば、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間への嵌入が可能であったとしても、第１から第３の連結体１３Ａ－１３Ｃを塑性域まで変形させてしまう可能性のある厚さのことである。主体２１は、自らの板厚の厚さ分の間隔で平行に配置された第１主平面２１ｃ及び第２主平面２１ｄを有する（図１から図９）。 The first to third connecting bodies 13A to 13C thus formed are thicker than the interval between the first reference plane 511 and the second reference plane 512 (that is, the thickness of the reference connected body 510). It is also connected to the second bus bar 20 (FIGS. 1 to 6). In the second busbar 20 , the main body 21 is formed to have a thickness greater than the interval between the first reference plane 511 and the second reference plane 512 (the thickness of the reference connected body 510 ). The plate thickness of the main body 21 is, for example, a thickness that cannot be inserted between the first connecting body 13A, the second connecting body 13B, and the third connecting body 13C. Further, the plate thickness of the main body 21 means, for example, even if it is possible to fit between the first connecting body 13A, the second connecting body 13B, and the third connecting body 13C, The thickness is such that the required holding force cannot be applied to the main body 21 from the connecting bodies 13A-13C. Further, the plate thickness of the main body 21 means, for example, even if it is possible to fit between the first connecting body 13A, the second connecting body 13B, and the third connecting body 13C, It is the thickness that may cause the connectors 13A-13C to deform into the plastic region. The main body 21 has a first main plane 21c and a second main plane 21d arranged in parallel with an interval corresponding to the thickness of the main body 21 (FIGS. 1 to 9).

第１から第３の連結体１３Ａ－１３Ｃは、第２バスバ２０に設けた被連結体２３に連結させる。よって、その被連結体２３は、第１押圧部１３ａからの押圧力を受ける第１被押圧部２３ａと、第２押圧部１３ｂからの押圧力を受ける第２被押圧部２３ｂと、第３押圧部１３ｃからの押圧力を受ける第３被押圧部２３ｃと、を有する（図１から図６）。ここで、この被連結体２３は、第１基準平面５１１及び第２基準平面５１２の間隔（基準被連結体５１０の板厚）と同じ間隔を空けて平行に配置された第１平面２３ｄ及び第２平面２３ｅを有する（図１から図６）。この被連結体２３においては、その第１平面２３ｄに第１被押圧部２３ａと第２被押圧部２３ｂとを設け、第２平面２３ｅに第３被押圧部２３ｃを設けている。よって、第１から第３の連結体１３Ａ－１３Ｃにおいては、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間に被連結体２３が配置されることによって、第１から第３の押圧部１３ａ－１３ｃから被連結体２３に対して基準被連結体５１０と同じ要求保持力を作用させることができる。従って、本実施形態のバスバ連結構造３０及び連結バスバ１においては、第１バスバ１０の第１から第３の連結体１３Ａ－１３Ｃについて、基準バスバ５００の基準被連結体５１０だけでなく、その基準被連結体５１０よりも厚みのある第２バスバ２０に対しても連結させることができる。即ち、このバスバ連結構造３０及び連結バスバ１は、第２バスバ２０に被連結体２３を設けることによって、基準バスバ５００や板厚違いの第２バスバ２０に対する第１バスバ１０の共用化を図ることができる。 The first to third connecting bodies 13A-13C are connected to a connected body 23 provided on the second bus bar 20. As shown in FIG. Therefore, the connected body 23 includes a first pressed portion 23a that receives the pressing force from the first pressing portion 13a, a second pressed portion 23b that receives the pressing force from the second pressing portion 13b, and a third pressing portion 23b. and a third pressed portion 23c that receives the pressing force from the portion 13c (FIGS. 1 to 6). Here, this connected body 23 is arranged in parallel with a first plane 23d and a second plane 23d which are arranged in parallel with the same distance as the distance between the first reference plane 511 and the second reference plane 512 (plate thickness of the reference connected body 510). It has two planes 23e (FIGS. 1 to 6). In this connected body 23, a first pressed portion 23a and a second pressed portion 23b are provided on the first plane 23d, and a third pressed portion 23c is provided on the second plane 23e. Therefore, in the first to third connecting bodies 13A to 13C, by placing the connected body 23 between the first connecting body 13A and the second connecting body 13B and the third connecting body 13C, the first Therefore, the same required holding force as the reference connected body 510 can be applied to the connected body 23 from the third pressing portions 13a to 13c. Therefore, in the busbar connecting structure 30 and the connecting busbar 1 of the present embodiment, the first to third connecting bodies 13A to 13C of the first busbar 10 are not only the reference connected body 510 of the reference busbar 500 but also the reference It can also be connected to the second bus bar 20 that is thicker than the connected body 510 . That is, in the bus bar connecting structure 30 and the connecting bus bar 1, by providing the connected body 23 to the second bus bar 20, the first bus bar 10 can be used in common with the reference bus bar 500 and the second bus bar 20 having a different plate thickness. can be done.

ここで、被連結体２３は、第１から第３の連結体１３Ａ－１３Ｃの延在方向に沿って第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間に嵌入させるものとして形成される。この被連結体２３は、主体２１における一方の端部２１ａの端面から第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間に嵌入させる。そこで、この被連結体２３は、主体２１における一方の端部２１ａ側（電気接続体２２が設けられている部分を除く）に設ける。この例示の第１平面２３ｄは、その主体２１の第１主平面２１ｃに設けている（図２及び図４から図６）。つまり、この例示の第１平面２３ｄは、その第１主平面２１ｃの一部を利用するものである。よって、この例示の第１平面２３ｄは、主体２１における一方の端部２１ａの端面に直交状態で連接している。また、この例示の第２平面２３ｅは、主体２１の第２主平面２１ｄに対して第１主平面２１ｃ及び第１平面２３ｄの側にオフセットさせて設けている（図１、図３、図５及び図６）。この第２平面２３ｅは、主体２１における一方の端部２１ａの端面に直交状態で連接させる。よって、第１から第３の連結体１３Ａ－１３Ｃにおいては、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間に被連結体２３を嵌入させることができる。そして、その被連結体２３は、第１連結体１３Ａ及び第２連結体１３Ｂと第３連結体１３Ｃとの間への嵌入が完了するまでの間、第１から第３の押圧部１３ａ－１３ｃから要求保持力以上の大きさの力を作用させないので、その力の反力による第１から第３の押圧部１３ａ－１３ｃの塑性変形を防ぐことができる。 Here, the connected body 23 is fitted between the first connecting body 13A and the second connecting body 13B and the third connecting body 13C along the extending direction of the first to third connecting bodies 13A to 13C. formed as a thing. This connected body 23 is fitted between the first connecting body 13A, the second connecting body 13B, and the third connecting body 13C from the end surface of one end portion 21a of the main body 21 . Therefore, this connected body 23 is provided on one end 21a side of the main body 21 (excluding the portion where the electrical connector 22 is provided). This exemplary first plane 23d is provided on the first major plane 21c of the main body 21 (FIGS. 2 and 4-6). That is, the illustrated first plane 23d utilizes a portion of the first main plane 21c. Therefore, the illustrated first plane 23d is connected to the end face of one end 21a of the main body 21 in a perpendicular state. In addition, the second plane 23e of this example is offset from the second main plane 21d of the main body 21 toward the first main plane 21c and the first plane 23d (FIGS. 1, 3, and 5). and FIG. 6). The second plane 23e is connected to the end face of one end 21a of the main body 21 in a perpendicular state. Therefore, in the first to third connecting bodies 13A to 13C, the connected body 23 can be fitted between the first connecting body 13A, the second connecting body 13B, and the third connecting body 13C. Then, until the connected body 23 is completely inserted between the first connecting body 13A, the second connecting body 13B, and the third connecting body 13C, the first to third pressing portions 13a to 13c are pressed. Since a force larger than the required holding force is not applied, plastic deformation of the first to third pressing portions 13a to 13c due to the reaction force of the force can be prevented.

具体的に、この例示の被連結体２３には、第２主平面２１ｄを第１主平面２１ｃ及び第１平面２３ｄの側にオフセットさせた溝部２３ｆを設ける（図１、図３、図５及び図６）。この被連結体２３においては、その溝部２３ｆの溝底を第２平面２３ｅとして利用する。よって、第３被押圧部２３ｃは、溝部２３ｆの溝底に設けられている。 Specifically, the exemplified connected body 23 is provided with a groove portion 23f in which the second main plane 21d is offset to the side of the first main plane 21c and the first plane 23d (FIGS. 1, 3, 5 and 5). Figure 6). In this connected body 23, the groove bottom of the groove portion 23f is used as the second plane 23e. Therefore, the third pressed portion 23c is provided at the groove bottom of the groove portion 23f.

その溝部２３ｆは、例えば、板厚を変えずに主体２１で第２平面２３ｅとして利用する部分をオフセットさせることによって形成される。このような溝部２３ｆの場合には、第２平面２３ｅに対して主体２１の板厚分だけ間隔を空けて平行に配置され、かつ、第１主平面２１ｃ及び第１平面２３ｄから突出させた突出平面２３ｇが形成される（図２及び図４から図６）。 The groove portion 23f is formed, for example, by offsetting a portion of the main body 21 that is used as the second plane 23e without changing the plate thickness. In the case of such a groove portion 23f, the protrusion is arranged parallel to the second plane 23e with a gap corresponding to the plate thickness of the main body 21, and protrudes from the first main plane 21c and the first plane 23d. A plane 23g is formed (FIGS. 2 and 4-6).

また、溝部２３ｆは、例えば、第２平面２３ｅが第１主平面２１ｃに対して基準被連結体５１０の板厚分だけ間隔を空けて平行に配置されるよう形成されたものであってもよい。例えば、この場合の溝部２３ｆは、第２主平面２１ｄを部分的に削り取ったものであってもよく、第２主平面２１ｄを部分的に押し潰したものであってもよい。また、この場合の溝部２３ｆは、第２バスバ２０を鋳造することによって、その金型で形成されたものであってもよい。 Further, the groove portion 23f may be formed, for example, so that the second plane 23e is arranged parallel to the first main plane 21c with a gap corresponding to the plate thickness of the reference connected body 510. . For example, the groove portion 23f in this case may be obtained by partially cutting off the second main plane 21d, or by partially crushing the second main plane 21d. Moreover, the groove part 23f in this case may be formed with the mold by casting the second bus bar 20 .

ここで、その溝部２３ｆは、自らの側壁２３ｆ1，２３ｆ2間に第３連結体１３Ｃを挟み込ませる形状で、かつ、それぞれの側壁２３ｆ1，２３ｆ2に第３連結体１３Ｃを係止させる形状のものとして形成されることが望ましい（図１及び図３）。これにより、被連結体２３は、その溝部２３ｆの中で主体２１の長手方向に沿う第３連結体１３Ｃの相対移動を抑えることができる。よって、このバスバ連結構造３０及び連結バスバ１においては、その長手方向に沿う第１バスバ１０と第２バスバ２０との間の相対移動を抑えることができ、かつ、その方向での第１バスバ１０と第２バスバ２０との間の位置決めを図ることができる。 Here, the groove portion 23f has a shape that allows the third connecting body 13C to be sandwiched between its own side walls 23f 1 and 23f 2 and has a shape that allows the third connecting body 13C to be locked to the respective side walls 23f 1 and 23f 2 . (FIGS. 1 and 3). Thereby, the connected body 23 can suppress the relative movement of the third connected body 13C along the longitudinal direction of the main body 21 in the groove portion 23f. Therefore, in the busbar connection structure 30 and the connection busbar 1, relative movement between the first busbar 10 and the second busbar 20 along the longitudinal direction can be suppressed, and the first busbar 10 can be prevented from moving in that direction. and the second bus bar 20 can be achieved.

以上示したように、本実施形態のバスバ連結構造３０及び連結バスバ１は、基準バスバ５００や板厚違いの第２バスバ２０に対する第１バスバ１０の共用化を図ることができる。このため、このバスバ連結構造３０及び連結バスバ１は、基準バスバ５００よりも厚い第２バスバ２０に連結させるための新設の第１バスバを用意する必要がない。よって、このバスバ連結構造３０及び連結バスバ１は、部品管理が容易になり、かつ、原価の低減を図ることができる。 As described above, the busbar coupling structure 30 and the coupling busbar 1 of the present embodiment can share the first busbar 10 with respect to the reference busbar 500 and the second busbar 20 having a different plate thickness. Therefore, the busbar connecting structure 30 and the connecting busbar 1 do not need to prepare a newly installed first busbar for connecting to the second busbar 20 that is thicker than the reference busbar 500 . Therefore, the busbar connection structure 30 and the connection busbar 1 can facilitate parts management and reduce costs.
