Abstract

A power distribution member (1) is provided with a pair of terminal fittings (10), and two braided wires (20) which have flexibility, are bundled and extend between the pair of terminal fittings (10), and each have both ends in the extension direction that are connected to the terminal fittings, respectively. As compared to when one large-sized braided wire is connected between the pair of terminal fittings (10), the surface area of a conductor increases, thereby enabling improved heat release performance between the pair of terminal fittings (10). Further, as compared to when one large-sized braided wire is connected between the pair of terminal fittings (10), the degree of freedom of each of the braided wires (20) increases, thereby enabling improved flexibility between the terminal fittings (10).

Description

配電部材Power distribution member
　本明細書で開示される技術は、配電部材に関する。 The technology disclosed in this specification relates to a power distribution member.
　従来、端子金具等の一対の接続部の間に編組線等の可撓性を有する導体が接続された配電部材が知られている。例えば特許文献１には、インバータ側接続端子とモータ側接続端子との間に編組線が接続された配電部材を備える端子台が開示されている。 Conventionally, a power distribution member is known in which a flexible conductor such as a braided wire is connected between a pair of connection portions such as a terminal fitting. For example, Patent Document 1 discloses a terminal block including a power distribution member in which a braided wire is connected between an inverter side connection terminal and a motor side connection terminal.
特開２０１１－１８７２２４号公報JP 2011-187224 A
　ところで、上記のような配電部材では、大電流を通電させる場合、接続部の間に接続される導体のサイズを大きくする必要がある。しかしながら、接続部のサイズを変更することなく導体のサイズを大きくすると、導体の一部を折り曲げる等して導体と接続部とを接続させる必要がある。この場合、導体と接続部との接続部位の形状が定まり難く、１つの導体において重なり合う部位も生じるため、接続部の間で導体の可撓性を確保することが困難となる。また、上記のような配電部材に大電流を通電させる場合、接続部の間の温度が上昇するため、接続部の間の導体に高い放熱性が要求される。 By the way, in the power distribution member as described above, when a large current is applied, it is necessary to increase the size of the conductor connected between the connection portions. However, if the size of the conductor is increased without changing the size of the connecting portion, it is necessary to connect the conductor and the connecting portion by bending a part of the conductor. In this case, it is difficult to determine the shape of the connection portion between the conductor and the connection portion, and a portion where one conductor overlaps is generated, so that it is difficult to ensure the flexibility of the conductor between the connection portions. In addition, when a large current is applied to the power distribution member as described above, the temperature between the connection portions rises, and thus high heat dissipation is required for the conductor between the connection portions.
　本明細書で開示される技術は、上記の課題に鑑みて創作されたものであって、接続部間の放熱性及び可撓性を向上させることを目的とする。 The technology disclosed in this specification has been created in view of the above-described problems, and aims to improve heat dissipation and flexibility between connecting portions.
　本明細書で開示される技術は、一対の接続部と、可撓性を有し、一対の前記接続部の間に束ねられて延在するとともに、その延在方向の両端部が前記接続部にそれぞれ接続された複数の導体と、を備える配電部材に関する。 The technology disclosed in the present specification includes a pair of connection portions and flexibility, and is bundled and extended between the pair of connection portions, and both ends in the extending direction thereof are the connection portions. And a plurality of conductors connected to each other.
　上記の配電部材によると、一対の接続部の間にサイズの大きな一つの導体が接続される場合と比べて、導体の表面積が増大するため、接続部間における放熱性を向上させることができる。また、一対の接続部の間にサイズの大きな一つの導体が接続される場合と比べて、サイズの小さな複数の導体が束ねられて接続されることで、接続部の間で各導体の自由度が増すため、接続部間の可撓性を向上させることができる。以上のように上記の配電部材では、接続部間の放熱性及び可撓性を向上させることができる。 According to the above power distribution member, since the surface area of the conductor is increased as compared with a case where one conductor having a large size is connected between the pair of connection portions, heat dissipation between the connection portions can be improved. Compared to the case where one large conductor is connected between a pair of connection parts, a plurality of small conductors are bundled and connected, so that the degree of freedom of each conductor between the connection parts. Therefore, the flexibility between the connecting portions can be improved. As described above, in the above power distribution member, heat dissipation and flexibility between the connecting portions can be improved.
　上記の配電部材において、複数の前記導体が同一種類のものとされてもよい。 In the above power distribution member, the plurality of conductors may be of the same type.
　この構成によると、種類の異なる複数の導体を用いることなく接続部間の放熱性及び柔軟性を向上させることができるため、部材点数の削減を図ることができる。 According to this configuration, since the heat dissipation and flexibility between the connecting portions can be improved without using a plurality of different types of conductors, the number of members can be reduced.
　上記の配電部材において、複数の前記導体は、前記延在方向から視た断面が幅方向に長い扁平形状とされ、前記延在方向と前記幅方向との両者に直交する厚み方向に積層した形で束ねられるとともに、その厚み方向の一方側の導体から他方側の導体に向かうにつれて前記延在方向の寸法が大きくなるものとされてもよい。 In the above power distribution member, the plurality of conductors have a shape in which a cross section viewed from the extending direction is a flat shape having a long width direction, and are stacked in a thickness direction orthogonal to both the extending direction and the width direction. And the dimension in the extending direction may be increased from the conductor on one side in the thickness direction toward the conductor on the other side.
　この構成によると、延在方向の寸法が等しい複数の導体が接続部間に接続される場合と比べて、導体の表面積が増大するため、接続部間の放熱性を一層向上させることができる。さらに上記の構成によると、接続部の間の距離は各編組線で等しいため、延在方向の寸法が他の編組線よりも相対的に大きな編組線がその厚み方向に撓んだ状態で接続部の間に接続され、厚み方向に積層した各導体の間に隙間が生じる。このため、当該隙間から熱が効果的に分散され、各導体の間に熱が籠り難くなり、配電部材の温度上昇を抑制することができる。 According to this configuration, since the surface area of the conductor is increased as compared with the case where a plurality of conductors having the same dimension in the extending direction are connected between the connection portions, the heat dissipation between the connection portions can be further improved. Further, according to the above configuration, since the distance between the connecting portions is equal in each braided wire, the braided wire whose dimension in the extending direction is relatively larger than the other braided wires is connected in a state where the braided wire is bent in the thickness direction. A gap is formed between the conductors connected between the portions and laminated in the thickness direction. For this reason, heat is effectively dispersed from the gap, and it is difficult for the heat to be generated between the conductors, and an increase in the temperature of the power distribution member can be suppressed.
　上記の配電部材において、複数の前記導体は、前記延在方向から視た断面が幅方向に長い扁平形状とされ、前記幅方向に並列した形で束ねられていてもよい。 In the power distribution member described above, the plurality of conductors may have a flat shape with a cross section viewed from the extending direction being long in the width direction, and may be bundled in parallel with each other in the width direction.
　この構成によると、複数の導体がその厚み方向に積層した形で束ねられた場合と比べて、各導体の間で対向する部位の表面積が小さくなるので、各導体の間に熱が籠り難くなり、配電部材の温度上昇を抑制することができる。 According to this configuration, compared to the case where a plurality of conductors are bundled in the form of being stacked in the thickness direction, the surface area of the opposing portions between the conductors is reduced, so that heat is not easily generated between the conductors. The temperature rise of the power distribution member can be suppressed.
　本明細書で開示される技術によれば、接続部間の放熱性及び可撓性を向上させることができる。 According to the technique disclosed in this specification, heat dissipation and flexibility between the connecting portions can be improved.

　一対の端子金具１０は、同一種類のものとされ、銅または銅合金からなるとともに、図２に示すように、厚み方向の寸法が異なる２つの部位１０Ａ，１０Ｂを有する。このうち厚み方向の寸法が相対的に小さな部位は、編組線２０の一端部が重ね合わされて固着された略平板状の端子側固着部１０Ａとされ、厚み方向の寸法が相対的に大きな部位は、編組線２０が固着されない略ブロック状の非固着部１０Ｂとされる。この非固着部１０Ｂは、図示しない相手側端子等と接続される。 The pair of terminal fittings 10 are of the same type, and are made of copper or a copper alloy and have two portions 10A and 10B having different dimensions in the thickness direction as shown in FIG. Of these, the part having a relatively small dimension in the thickness direction is a substantially flat terminal-side fixing part 10A in which one end of the braided wire 20 is overlapped and fixed, and the part having a relatively large dimension in the thickness direction is The braided wire 20 is a non-fixed portion 10B having a substantially block shape to which the braided wire 20 is not fixed. The non-fixed portion 10B is connected to a counterpart terminal or the like (not shown).
　２つの編組線２０は、同一種類のものとされており、延在方向の寸法、幅方向の寸法、及び厚み方向の寸法がいずれも等しいものとされる。各編組線２０は、それぞれ延在方向から視た断面が幅方向に長い扁平形状とされており（図３参照）、その厚み方向はその延在方向とその幅方向との両者と直交する。また、各編組線２０の幅方向の寸法は、各端子金具１０における端子側固着部１０Ａの幅方向の寸法と等しくなっている。 The two braided wires 20 are of the same type, and the dimension in the extending direction, the dimension in the width direction, and the dimension in the thickness direction are all equal. Each braided wire 20 has a flat shape whose cross section viewed from the extending direction is long in the width direction (see FIG. 3), and the thickness direction is orthogonal to both the extending direction and the width direction. Further, the dimension in the width direction of each braided wire 20 is equal to the dimension in the width direction of the terminal side fixing portion 10 </ b> A in each terminal fitting 10.
　各編組線２０は、銅または銅合金からなる複数の細い金属素線２２（図１参照）を網目状に編み込んだ電線とされている。金属素線２２の表面には錫めっきが施されることにより錫めっき層（不図示）が形成されており、金属素線２２の酸化や錆の発生が抑制されている。 Each braided wire 20 is an electric wire in which a plurality of thin metal wires 22 (see FIG. 1) made of copper or copper alloy are knitted in a mesh shape. A tin plating layer (not shown) is formed on the surface of the metal strand 22 by performing tin plating, and the occurrence of oxidation and rust of the metal strand 22 is suppressed.
　２つの編組線２０は、一対の端子金具１０の間に束ねられて延在しており、その延在方向の両端部がそれぞれ端子金具１０と接続されている。具体的には、２つの編組線２０は、図２及び図３に示すように、その延在方向における位置が互いに一致するとともにその幅方向における位置が互いに一致するように、その厚み方向に隙間無く積層した形で束ねられている。 The two braided wires 20 are bundled and extended between the pair of terminal fittings 10, and both end portions in the extending direction are connected to the terminal fitting 10, respectively. Specifically, as shown in FIGS. 2 and 3, the two braided wires 20 are spaced in the thickness direction so that the positions in the extending direction coincide with each other and the positions in the width direction coincide with each other. They are bundled in a laminated form.
　各編組線２０の両端部は、それぞれ端子金具１０の端子側固着部１０Ａと重ね合わされ、抵抗溶接によって固着された編組線側固着部２０Ａとされる。各編組線２０の編組線側固着部２０Ａは、図２に示すように、編組線２０の厚み方向に圧縮され、端子金具１０の端子側固着部１０Ａ及び金属素線２２の錫めっき層から溶融した錫めっきによって固められることで、端子金具１０の端子側固着部１０Ａと固着されて接続されている。なお、各編組線２０の編組線側固着部２０Ａは、端子金具１０の端子側固着部１０Ａの幅方向における全域に亘って固着されている。 Both end portions of each braided wire 20 are overlapped with the terminal side fixing portion 10A of the terminal fitting 10, respectively, and become a braided wire side fixing portion 20A fixed by resistance welding. As shown in FIG. 2, the braided wire side fixing portion 20 </ b> A of each braided wire 20 is compressed in the thickness direction of the braided wire 20 and melted from the terminal side fixing portion 10 </ b> A of the terminal fitting 10 and the tin plating layer of the metal strand 22. By being solidified by the tin plating, the terminal side fixing part 10A of the terminal fitting 10 is fixed and connected. The braided wire side fixing portion 20A of each braided wire 20 is fixed over the entire region in the width direction of the terminal side fixing portion 10A of the terminal fitting 10.
　ここで、端子金具１０の端子側固着部１０Ａのサイズを変更することなく、本実施形態で示す編組線２０よりもサイズの大きな編組線が一対の端子金具１０の間に接続される場合、例えば延在方向の寸法及び厚み方向の寸法が本実施形態で示す編組線２０のものと等しく、幅方向の寸法が本実施形態で示す編組線２０の約２倍の寸法とされた編組線（以下、幅広編組線と称する）を接続させることができる。 Here, when a braided wire having a size larger than the braided wire 20 shown in the present embodiment is connected between the pair of terminal fittings 10 without changing the size of the terminal side fixing portion 10A of the terminal fitting 10, for example, A braided wire (hereinafter referred to as a braided wire 20) whose dimensions in the extending direction and the thickness direction are equal to those of the braided wire 20 shown in the present embodiment and whose dimensions in the width direction are about twice that of the braided wire 20 shown in the present embodiment , Referred to as a wide braided wire).
　これに対し本実施形態の配電部材１では、上述したように一対の端子金具１０の間に２つの編組線２０が束ねられて接続されるため、一対の端子金具１０の間にサイズの大きな一つの編組線、例えば上記幅広編組線が接続される場合と比べて、編組線２０の表面積が増大する。このため、一対の端子金具１０の間にサイズの大きな一つの編組線が接続される場合と比べて、一対の端子金具１０の間における放熱性を向上させることができる。このように本実施形態の配電部材１では、端子金具１０のサイズを変更することなく、放熱性を向上させることができ、大電流を通電した場合であっても効果的に放熱させることができる。 On the other hand, in the power distribution member 1 of the present embodiment, the two braided wires 20 are bundled and connected between the pair of terminal fittings 10 as described above. The surface area of the braided wire 20 is increased as compared to the case where two braided wires, for example, the wide braided wire is connected. For this reason, compared with the case where one large braided wire is connected between a pair of terminal metal fittings 10, the heat dissipation between a pair of terminal metal fittings 10 can be improved. Thus, in the power distribution member 1 of this embodiment, heat dissipation can be improved without changing the size of the terminal fitting 10, and even when a large current is applied, heat can be effectively radiated. .
　また、一対の端子金具１０の間にサイズの大きな一つの編組線、例えば上記幅広編組線が接続される場合、当該幅広編組線の幅方向の両端部を折り返して厚み方向に重ねた状態で、端子金具１０と接続されることとなる。このため、一対の端子金具１０の間において幅広編組線が撓み難いものとなる。これに対し本実施形態の配電部材１では、上述したように一対の端子金具１０の間に２つの編組線２０が束ねられて接続されるため、端子金具１０の間において編組線２０の自由度が増し、一対の端子金具１０の間の可撓性を向上させることができる。このように本実施形態の配電部材１では、端子金具１０のサイズを変更することなく、端子金具１０の間の可撓性を向上させることができ、配電部材１を相手側端子等に組付ける際の作業性等を向上させることができる。 In addition, when one large braided wire, for example, the above wide braided wire is connected between the pair of terminal fittings 10, the widthwise ends of the wide braided wire are folded and overlapped in the thickness direction, The terminal fitting 10 is connected. For this reason, the wide braided wire is difficult to bend between the pair of terminal fittings 10. On the other hand, in the power distribution member 1 of the present embodiment, since the two braided wires 20 are bundled and connected between the pair of terminal fittings 10 as described above, the degree of freedom of the braided wire 20 between the terminal fittings 10. The flexibility between the pair of terminal fittings 10 can be improved. Thus, in the power distribution member 1 of this embodiment, the flexibility between the terminal metal fittings 10 can be improved without changing the size of the terminal metal fittings 10, and the power distribution member 1 is assembled to a counterpart terminal or the like. The workability at the time can be improved.
　また、一対の端子金具１０の間に上記のような幅広編組線が接続される場合、上記のように幅広編組線の一部が折り返して接続されるため、幅広編組線と端子金具１０との接続部位の形状が定まり難くなる。これに対し、本実施形態の配電部材１では、上述したように一対の端子金具１０の間に２つの編組線２０が束ねられて接続されるため、各編組線２０と端子金具１０との接続部位の形状が定まり、当該接続部位における品質（引張強度や抵抗等）を安定化させることができる。 Further, when the wide braided wire as described above is connected between the pair of terminal fittings 10, since a part of the wide braided wire is folded back as described above, the wide braided wire and the terminal fitting 10 are connected. The shape of the connection site is difficult to determine. In contrast, in the power distribution member 1 of the present embodiment, since the two braided wires 20 are bundled and connected between the pair of terminal fittings 10 as described above, the connection between each braided wire 20 and the terminal fitting 10 is performed. The shape of the part is determined, and the quality (tensile strength, resistance, etc.) at the connection part can be stabilized.
　また、本実施形態の配電部材１では、一対の端子金具１０の間に接続される２つの編組線２０が同一種類のものとされているため、種類の異なる２つの編組線を用いることなく一対の端子金具１０の間の放熱性及び柔軟性を向上させることができる。このため、種類の異なる２つの編組線を用いる場合と比べて、部材点数の削減を図ることができる。 Moreover, in the power distribution member 1 of this embodiment, since the two braided wires 20 connected between the pair of terminal fittings 10 are of the same type, a pair without using two different braided wires. The heat dissipation and flexibility between the terminal fittings 10 can be improved. For this reason, compared with the case where two types of braided wires are used, the number of members can be reduced.
　＜実施形態２＞
　次に、実施形態２について図４を参照して説明する。本実施形態の配電部材１０１は、２つの編組線１２０，１２１の延在方向の寸法が互いに異なる点で実施形態１のものと異なっている。その他の構成については実施形態１のものと同様であるため、構造、作用、及び効果の説明は省略する。なお、図４では、紙面左右方向が編組線１２０，１２１の延在方向と一致し、紙面上下方向が端子金具１１０及び編組線１２０，１２１の厚み方向と一致する。また、図４において、図２の参照符号に数字１００を加えた部位は、実施形態１で説明した部位と同一である。 <Embodiment 2>
Next, Embodiment 2 will be described with reference to FIG. The power distribution member 101 of the present embodiment is different from that of the first embodiment in that the dimensions of the two braided wires 120 and 121 in the extending direction are different from each other. Since the other configuration is the same as that of the first embodiment, the description of the structure, operation, and effect is omitted. In FIG. 4, the horizontal direction on the paper surface coincides with the extending direction of the braided wires 120 and 121, and the vertical direction on the paper surface coincides with the thickness direction of the terminal fitting 110 and the braided wires 120 and 121. Further, in FIG. 4, the part obtained by adding the numeral 100 to the reference sign in FIG. 2 is the same as the part described in the first embodiment.
　本実施形態の配電部材１０１では、図４に示すように、実施形態１と同様、一対の端子金具１１０の間に２つの編組線１２０，１２１がその厚み方向に積層した形で束ねられている。２つの編組線１２０，１２１は、その延在方向の寸法が異なっており、一方の編組線１２１の延在方向の寸法が他方の編組線１２０の延在方向の寸法よりも相対的に長くなっている。換言すれば、各編組線１２０，１２１は、その厚み方向の一方側の編組線１２０から他方側の編組線１２１に向かうにつれて延在方向の寸法が大きくなっている。 In the power distribution member 101 of the present embodiment, as shown in FIG. 4, as in the first embodiment, two braided wires 120 and 121 are bundled between the pair of terminal fittings 110 so as to be stacked in the thickness direction. . The two braided wires 120 and 121 have different dimensions in the extending direction, and the dimension in the extending direction of one braided wire 121 is relatively longer than the dimension in the extending direction of the other braided wire 120. ing. In other words, each braided wire 120, 121 has a dimension in the extending direction that increases from the braided wire 120 on one side in the thickness direction toward the braided wire 121 on the other side.
　ここで、配電部材１０１において一対の端子金具１１０の間の距離は各編組線１２０，１２１で等しいので、図４に示すように、延在方向の寸法が相対的に長い上記一方の編組線１２１がその厚み方向に撓んだ状態で一対の端子金具１１０の間に接続されている。このため、配電部材１０１では、図４に示すように、厚み方向に積層した２つの編組線１２０，１２１の間に隙間Ｓが生じている。 Here, since the distance between the pair of terminal fittings 110 in the power distribution member 101 is equal between the braided wires 120 and 121, as shown in FIG. 4, the one braided wire 121 having a relatively long dimension in the extending direction. Are connected between the pair of terminal fittings 110 while being bent in the thickness direction. For this reason, in the power distribution member 101, as shown in FIG. 4, a gap S is generated between the two braided wires 120 and 121 stacked in the thickness direction.
　このように本実施形態の配電部材１０１では、厚み方向に積層した２つの編組線１２０，１２１の間に隙間Ｓが生じていることから、この隙間Ｓから熱が効果的に分散され、２つの編組線がその厚み方向に隙間なく積層している場合と比べて、２つの編組線１２０，１２１の間に熱が籠り難いものとなる。その結果、配電部材１０１の温度上昇を抑制することができる。 Thus, in the power distribution member 101 of this embodiment, since the gap S is generated between the two braided wires 120 and 121 laminated in the thickness direction, heat is effectively dispersed from the gap S, and the two Compared with the case where the braided wires are laminated without gaps in the thickness direction, heat is less likely to be generated between the two braided wires 120 and 121. As a result, the temperature rise of the power distribution member 101 can be suppressed.
　また、本実施形態の配電部材１０１では、一方の編組線１２１の延在方向の寸法が他方の編組線１２０の延在方向の寸法よりも相対的に長くなっていることで、延在方向の寸法が等しい２つの編組線が一対の端子金具１１０の間に接続される場合と比べて、編組線１２０，１２１の表面積が増大する。このため、一対の端子金具１１０の間の放熱性を一層向上させることができる。 Further, in the power distribution member 101 of the present embodiment, the dimension in the extending direction of one braided wire 121 is relatively longer than the dimension in the extending direction of the other braided wire 120, so that Compared with the case where two braided wires having the same dimensions are connected between the pair of terminal fittings 110, the surface areas of the braided wires 120 and 121 are increased. For this reason, the heat dissipation between the pair of terminal fittings 110 can be further improved.
　なお、延在方向の寸法が等しい２つの編組線がその厚み方向に隙間なく積層している場合であっても、２つの編組線１２０，１２１の間にスペーサ部材等を挟み込むことで、２つの編組線１２０，１２１の間に強制的に隙間を生じさせることができる。しかしながら、この場合、部材点数の増加によって部材コストが増大し、さらに、２つの編組線１２０，１２１の間にスペーサ部材等を挟み込むための作業やその作業に伴う治具等も必要となる。また、強制的に隙間を生じさせることで、配電部材の保持の面で問題が生じる。これに対し本実施形態では、２つの編組線１２０，１２１の延在方向の寸法が異なるようにすることで、別途部材を必要とすることなく、また、別途作業を必要とすることなく、２つの編組線１２０，１２１の間に隙間Ｓを生じさせることができる。 Even when two braided wires having the same dimension in the extending direction are laminated without gaps in the thickness direction, two spacer wires are sandwiched between the two braided wires 120 and 121 to A gap can be forcibly generated between the braided wires 120 and 121. However, in this case, the member cost increases due to the increase in the number of members, and an operation for sandwiching the spacer member between the two braided wires 120 and 121 and a jig accompanying the operation are also required. Further, forcibly creating a gap causes a problem in terms of holding the power distribution member. On the other hand, in this embodiment, by making the dimension in the extending direction of the two braided wires 120 and 121 different, no additional member is required and no additional work is required. A gap S can be generated between the two braided wires 120, 121.
　＜実施形態３＞
　次に、実施形態３について図５を参照して説明する。本実施形態の配電部材２０１は、一対の端子金具２１０の間に束ねられて延在する編組線２２０の数が実施形態１のものと異なっている。その他の構成については実施形態１のものと同様であるため、構造、作用、及び効果の説明は省略する。なお、図５では、紙面左右方向が編組線２２０の延在方向と一致し、紙面上下方向が端子金具２１０及び編組線２２０の厚み方向と一致する。また、図５において、図２の参照符号に数字２００を加えた部位は、実施形態１で説明した部位と同一である。 <Embodiment 3>
Next, Embodiment 3 will be described with reference to FIG. The power distribution member 201 of the present embodiment is different from that of the first embodiment in the number of braided wires 220 that are bundled and extended between a pair of terminal fittings 210. Since the other configuration is the same as that of the first embodiment, the description of the structure, operation, and effect is omitted. In FIG. 5, the left-right direction on the paper surface coincides with the extending direction of the braided wire 220, and the up-down direction on the paper surface coincides with the thickness direction of the terminal fitting 210 and the braided wire 220. Further, in FIG. 5, the part obtained by adding the numeral 200 to the reference sign in FIG. 2 is the same as the part described in the first embodiment.
　本実施形態の配電部材２０１では、図５に示すように、一対の端子金具２１０の間に３つの編組線２２０がその厚み方向に互いに隙間無く積層した形で束ねられている。３つの編組線２２０は、同一種類のものとされており、延在方向の寸法、幅方向の寸法、及び厚み方向の寸法がいずれも等しいものとされる。このような構成とされた本実施形態の配電部材２０１では、実施形態１の配電部材１のように２つの編組線２０がその厚み方向に隙間無く積層した構成と比べて、編組線２２０の断面積が増大するので、一対の端子金具２１０の間により多くの電流を通電させることができる。 In the power distribution member 201 of the present embodiment, as shown in FIG. 5, three braided wires 220 are bundled between the pair of terminal fittings 210 so as to be laminated without gaps therebetween in the thickness direction. The three braided wires 220 are of the same type, and the dimension in the extending direction, the dimension in the width direction, and the dimension in the thickness direction are all equal. In the power distribution member 201 of the present embodiment configured as described above, the braided wire 220 is cut off as compared with the structure in which the two braided wires 20 are laminated without gaps in the thickness direction as in the power distribution member 1 of the first embodiment. Since the area increases, more current can be passed between the pair of terminal fittings 210.
　＜実施形態４＞
　次に、実施形態４について図６を参照して説明する。本実施形態の配電部材３０１は、２つの編組線３２０の束ねられる態様が実施形態１のものと異なっている。その他の構成については実施形態１のものと同様であるため、構造、作用、及び効果の説明は省略する。なお、図６では、紙面左右方向が編組線３２０の延在方向と一致し、紙面上下方向が端子金具３１０及び編組線３２０の幅方向と一致する。また、図６において、図１の参照符号に数字３００を加えた部位は、実施形態１で説明した部位と同一である。 <Embodiment 4>
Next, Embodiment 4 will be described with reference to FIG. The power distribution member 301 of the present embodiment is different from that of the first embodiment in that the two braided wires 320 are bundled. Since the other configuration is the same as that of the first embodiment, the description of the structure, operation, and effect is omitted. In FIG. 6, the horizontal direction on the paper surface coincides with the extending direction of the braided wire 320, and the vertical direction on the paper surface coincides with the width direction of the terminal fitting 310 and the braided wire 320. Further, in FIG. 6, the part obtained by adding the numeral 300 to the reference numeral in FIG. 1 is the same as the part described in the first embodiment.
　本実施形態の配電部材３０１では、図６に示すように、一対の端子金具３１０の間に２つの編組線３２０がその厚み方向ではなく、その幅方向に並列した形で束ねられている。２つの編組線３２０は、同一種類のものとされており、延在方向の寸法、幅方向の寸法、及び厚み方向の寸法がいずれも等しいものとされる。このため、各編組線３２０の両端部（編組線側固着部３２０Ａ）は、編組線３２０の幅方向に圧縮された状態で端子金具３１０の端子側固着部と固着されて接続されている。 In the power distribution member 301 of the present embodiment, as shown in FIG. 6, two braided wires 320 are bundled between a pair of terminal fittings 310 in parallel with each other in the width direction, not in the thickness direction. The two braided wires 320 are of the same type, and the dimension in the extending direction, the dimension in the width direction, and the dimension in the thickness direction are all equal. Therefore, both end portions (braided wire side fixing portion 320A) of each braided wire 320 are fixedly connected to the terminal side fixing portion of the terminal fitting 310 while being compressed in the width direction of the braided wire 320.
　以上のような構成とされた本実施形態の配電部材３０１では、編組線３２０の断面が幅方向に長い扁平形状とされていることから、２つの編組線がその厚み方向に積層した形で束ねられた場合と比べて、２つの編組線３２０の間で対向する部位（図６の参照符号３２０Ｃで示す部位）の表面積が小さくなり、２つの編組線３２０の間に熱が籠り難くなる。このため、２つの編組線がその厚み方向に積層した形で束ねられた場合と比べて、配電部材３０１の温度上昇を抑制することができる。 In the power distribution member 301 of the present embodiment configured as described above, since the cross section of the braided wire 320 is a flat shape that is long in the width direction, the two braided wires are bundled in a stacked manner in the thickness direction. Compared with the case where it is made, the surface area of the site | part (part shown by 320 C of reference numerals of FIG. 6) which opposes between the two braided wires 320 becomes small, and it becomes difficult to heat between the two braided wires 320. FIG. For this reason, the temperature rise of the power distribution member 301 can be suppressed compared with the case where two braided wires are bundled in the form of being laminated in the thickness direction.
　＜実施形態５＞
　次に、実施形態５について図７を参照して説明する。本実施形態の配電部材４０１は、２つの編組線４２０，４２１の幅方向の寸法が互いに点で実施形態１のものと異なっている。その他の構成については実施形態１のものと同様であるため、構造、作用、及び効果の説明は省略する。なお、図７では、紙面左右方向が編組線４２０，４２１の延在方向と一致し、紙面上下方向が端子金具４１０及び編組線４２０，４２１の厚み方向と一致する。また、図７において、図１の参照符号に数字４００を加えた部位は、実施形態１で説明した部位と同一である。 <Embodiment 5>
Next, Embodiment 5 will be described with reference to FIG. The power distribution member 401 of the present embodiment is different from that of the first embodiment in that the dimensions of the two braided wires 420 and 421 in the width direction are different from each other. Since the other configuration is the same as that of the first embodiment, the description of the structure, operation, and effect is omitted. In FIG. 7, the horizontal direction on the paper surface coincides with the extending direction of the braided wires 420 and 421, and the vertical direction on the paper surface coincides with the thickness direction of the terminal fitting 410 and the braided wires 420 and 421. In FIG. 7, a part obtained by adding the numeral 400 to the reference numeral in FIG. 1 is the same as the part described in the first embodiment.
　本実施形態の配電部材４０１では、図７に示すように、一対の端子金具４１０の間に２つの編組線４２０，４２１がその厚み方向に隙間無く積層した形で束ねられている。２つの編組線４２０，４２１は、その幅方向の寸法が異なっており、一方の編組線４２０の幅方向の寸法が他方の編組線４２１の幅方向の寸法よりも相対的に大きくなっている。 In the power distribution member 401 of this embodiment, as shown in FIG. 7, two braided wires 420 and 421 are bundled between a pair of terminal fittings 410 so as to be laminated without gaps in the thickness direction. The two braided wires 420 and 421 have different dimensions in the width direction, and the dimension in the width direction of one braided wire 420 is relatively larger than the dimension in the width direction of the other braided wire 421.
　本実施形態では、このように、一対の端子金具４１０の間に束ねられた２つの編組線４２０，４２１の種類が異なる場合であっても、一対の端子金具４１０の間にサイズの大きな一つの編組線が接続される場合と比べて、編組線４２０，４２１の表面積が増大するため、一対の端子金具４１０の間における放熱性を向上させることができる。また、一対の端子金具４１０の間にサイズの大きな一つの編組線が接続される場合と比べて、端子金具４１０の間において各編組線４２０，４２１の自由度も増すため、端子金具４１０の間の可撓性を向上させることができる。 In the present embodiment, in this way, even if the types of the two braided wires 420 and 421 bundled between the pair of terminal fittings 410 are different, one large size is provided between the pair of terminal fittings 410. Compared with the case where the braided wire is connected, the surface area of the braided wires 420 and 421 increases, so that the heat dissipation between the pair of terminal fittings 410 can be improved. In addition, since the degree of freedom of the braided wires 420 and 421 is increased between the terminal fittings 410 as compared to a case where one large braided wire is connected between the pair of terminal fittings 410, The flexibility can be improved.
　上記の実施形態の他の変形例を以下に列挙する。
