　以下、第１実施形態に係る電気接続部品及びこれを備えるワイヤーハーネスについて説明する。図１は、第１実施形態に係る電気接続部品２０及びこれを備えるワイヤーハーネス１０を示す斜視図である。図２は、第１実施形態に係る電気接続部品２０を示す側面図である。図３は、図２のＩＩＩ－ＩＩＩ線に沿って切断した断面図である。図４は、電気接続部２１と外部導体との接続構造を示す説明図である。 {First embodiment}
Hereinafter, the electrical connection component according to the first embodiment and the wire harness including the electrical connection component will be described. FIG. 1 is a perspective view showing an electrical connection component 20 and a wire harness 10 including the electrical connection component 20 according to the first embodiment. FIG. 2 is a side view showing the electrical connection component 20 according to the first embodiment. 3 is a cross-sectional view taken along line III-III in FIG. FIG. 4 is an explanatory diagram showing a connection structure between the electrical connection portion 21 and the external conductor.
　ワイヤーハーネス１０は、電線１２と、電線１２に接続される電気接続部品２０と、電気接続部品２０に接続される外部導体とを備える。本実施形態は、外部導体が端子付電線７０（より詳細には、端子付電線７０における端子７４）である事例である。この際、複数の端子付電線７０が、１つの電気接続部品２０に接続されている。ここでは、電線１２が電源線であり、電気接続部品２０を介して複数の端子付電線７０に電源が分配されるものとして説明する。従って、ここでは、電気接続部品２０は電源分配機能を有する。 The wire harness 10 includes an electric wire 12, an electric connection component 20 connected to the electric wire 12, and an external conductor connected to the electric connection component 20. This embodiment is an example in which the outer conductor is the terminal-attached electric wire 70 (more specifically, the terminal 74 in the terminal-attached electric wire 70). At this time, the plurality of electric wires with terminals 70 are connected to one electrical connecting component 20. Here, the description will be made assuming that the electric wire 12 is a power supply line, and the power is distributed to the plurality of electric wires 70 with terminals via the electrical connection component 20. Therefore, here, the electrical connection component 20 has a power distribution function.
　電線１２は、横断面が偏平な金属板１４を含む。さらにここでは、電線１２は、金属板１４の周囲を覆う被覆１６を含む。 The electric wire 12 includes a metal plate 14 having a flat cross section. Furthermore, here, the electric wire 12 includes a coating 16 that covers the periphery of the metal plate 14.
　金属板１４は、長尺形状に形成されており、その長手方向に対して直交する面における横断面が偏平形状（ここでは、一方向に長い長方形状）に形成されている。従って、金属板１４は、細長い帯状に形成されている。金属板１４は、銅、銅合金、アルミニウム、アルミニウム合金などの材料によって形成される。金属板１４には、スズやニッケルなどの金属めっきが施されていても良い。 The metal plate 14 is formed in a long shape, and a cross section in a plane orthogonal to the longitudinal direction is formed in a flat shape (here, a rectangular shape long in one direction). Therefore, the metal plate 14 is formed in an elongated strip shape. The metal plate 14 is formed of a material such as copper, a copper alloy, aluminum, or an aluminum alloy. The metal plate 14 may be subjected to metal plating such as tin or nickel.
　かかる金属板１４は、単線として機能する。金属板１４を単線として用いることによって、複数の素線で一つの導電路を成す場合と比較して、断面積を大きく設定しやすくなり、大電流に対応させることが容易となる。このとき金属板１４が偏平であることによって、車両において狭いスペースに配設させやすくなる。この点から、車両に配設するうえで、円形断面の単線を用いる場合と比較した場合でも、断面積を大きく設定しやすくなり、大電流に対応させることが容易となる。なお、金属板１４は、長手方向に沿って、一続きに形成されていてもよいし、分割された分割体が連結されて形成されていてもよい。 The metal plate 14 functions as a single wire. By using the metal plate 14 as a single wire, it becomes easier to set a cross-sectional area larger than in the case where a plurality of strands form one conductive path, and it is easy to cope with a large current. Since the metal plate 14 is flat at this time, it becomes easy to arrange | position in a narrow space in a vehicle. From this point, it is easy to set a large cross-sectional area and cope with a large current even when compared with the case where a single wire having a circular cross section is used in the vehicle. In addition, the metal plate 14 may be formed continuously along the longitudinal direction, or may be formed by connecting divided parts.
　被覆１６は、上記金属板１４を偏平な形態で覆う絶縁部材である。被覆１６は、例えば、金属板１４の周囲に樹脂を押出被覆すること等によって形成される。被覆１６は、金属板１４の周囲を均一な厚み寸法で覆っており、従って、電線１２を、その長手方向に対して直交する横断面で観察すると、偏平形状を呈する。 The covering 16 is an insulating member that covers the metal plate 14 in a flat shape. The coating 16 is formed, for example, by extrusion coating a resin around the metal plate 14. The coating 16 covers the periphery of the metal plate 14 with a uniform thickness. Therefore, when the electric wire 12 is observed in a cross section orthogonal to the longitudinal direction, it has a flat shape.
　上記電線１２は、例えば、車両においてバッテリと、ＤＣ－ＤＣコンバータ、スタータ・ジェネレータ又はインバータ等とを電気的につなぐ電力系の配線部材として用いられることが好ましい。 The wire 12 is preferably used as a power system wiring member that electrically connects a battery and a DC-DC converter, a starter / generator, an inverter, or the like in a vehicle.
　ここでは、電線１２のうち長手方向中間部分に電気接続部品２０が接続されている。また、ここでは、電気接続部品２０は、電線１２のうち被覆１６が皮剥ぎされた部分に接続されている。もっとも、電線用接続部品は、被覆１６が皮剥ぎされていない部分に接続されるものであってもよい。このような電線用接続部品について詳しくは後述する。 Here, the electrical connection component 20 is connected to the middle portion of the electric wire 12 in the longitudinal direction. Here, the electrical connection component 20 is connected to a portion of the electric wire 12 where the coating 16 is peeled off. But the connection part for electric wires may be connected to the part which the coating | coated 16 is not stripped. Details of such connecting parts for electric wires will be described later.
　電気接続部品２０は、電気接続部２１と、ハウジング５０と、を備える。 The electrical connection component 20 includes an electrical connection portion 21 and a housing 50.
　電気接続部２１は、金属板に接触して電気的接続する金属板側接続部と、金属板側接続部に連なり外部導体が接続される少なくとも１つの外部導体側接続部とを含む。本実施形態において、電気接続部２１は、複数の外部導体側接続部を含む。さらに、電気接続部２１は、金属板側接続部と複数の外部導体側接続部それぞれとの間に介在する複数のヒューズ２２を含む。本実施形態では、金属板側接続部を含む部材として、バスバ３０が設けられている。また、外部導体側接続部は端子形状に形成されており、外部導体側接続部を含む部材として、中継端子４０が設けられている。 The electrical connection portion 21 includes a metal plate side connection portion that contacts and electrically connects to the metal plate, and at least one external conductor side connection portion that is connected to the metal plate side connection portion and to which an external conductor is connected. In the present embodiment, the electrical connection portion 21 includes a plurality of external conductor side connection portions. Furthermore, the electrical connection portion 21 includes a plurality of fuses 22 interposed between the metal plate side connection portion and each of the plurality of external conductor side connection portions. In this embodiment, the bus bar 30 is provided as a member including the metal plate side connection portion. Moreover, the external conductor side connection part is formed in the terminal shape, and the relay terminal 40 is provided as a member containing the external conductor side connection part.
　ヒューズ２２は、複数設けられている。複数のヒューズ２２は、バスバ３０を介して金属板１４に接続されている。また、各ヒューズ２２には、外部導体が接続される。具体的には、ヒューズ２２は、ヒューズエレメント２４と、ヒューズエレメント２４の一部を収めるケース２８とを含む。 A plurality of fuses 22 are provided. The plurality of fuses 22 are connected to the metal plate 14 via the bus bar 30. An external conductor is connected to each fuse 22. Specifically, the fuse 22 includes a fuse element 24 and a case 28 that houses a part of the fuse element 24.
　ヒューズエレメント２４は、一対の端子部２５、２６と、その間に設けられた溶断部２７とを含む。ヒューズエレメント２４は、例えば低融点金属材料の亜鉛合金（ＺｎＡｌなど）又は銅合金（Ｃｕ－Ｆｅ系など）等からなる金属板がプレス打ち抜き加工されて形成される。 The fuse element 24 includes a pair of terminal portions 25 and 26 and a fusing portion 27 provided therebetween. The fuse element 24 is formed, for example, by stamping a metal plate made of a low melting point metal material such as a zinc alloy (ZnAl or the like) or a copper alloy (Cu-Fe type or the like).
　一対の端子部２５、２６は、それぞれ平板状に形成された一端側端子部２５と、他端側端子部２６とで構成されている。端子部２５、２６の先端側がそれぞれ別の相手側に接続される一方、端子部２５、２６の基端側が溶断部２７を介して接続されている。一端側端子部２５は、相手側としてのバスバ３０の後述するヒューズ接続部３２と接続される。また、他端側端子部２６は、相手側としての中継端子４０の後述するヒューズ接続部４２と接続される。ここで、端子部２５、２６は、先端に行くにつれて幅が狭くなるテーパ状に形成されており、ヒューズ接続部３２、４２のスロット３３、４３への挿入がスムーズに行えるようになっている。各端子部２５、２６の形状は、タブ端子とも呼ばれる。 The pair of terminal portions 25 and 26 includes a first end side terminal portion 25 and a second end side terminal portion 26 each formed in a flat plate shape. The distal end sides of the terminal portions 25 and 26 are respectively connected to different counterpart sides, while the proximal end sides of the terminal portions 25 and 26 are connected via a fusing portion 27. The one end side terminal portion 25 is connected to a fuse connecting portion 32 described later of the bus bar 30 as a counterpart side. Moreover, the other end side terminal part 26 is connected with the fuse connection part 42 mentioned later of the relay terminal 40 as a counterpart. Here, the terminal portions 25 and 26 are formed in a tapered shape whose width becomes narrower toward the tip, so that the insertion of the fuse connection portions 32 and 42 into the slots 33 and 43 can be smoothly performed. The shape of each terminal part 25 and 26 is also called a tab terminal.
　溶断部２７は、端子部２５、２６よりも細幅とされて過電流が流れた際にジュール熱により溶断し易くなっている。溶断部２７は、一対の端子部２５、２６と共に一体的に形成されている。なお、図４に示す例では、溶断部２７は、端子部２５、２６の側面に接続されているが、溶断部２７と端子部２５、２６との接続位置は上記したものに限られない。例えば、溶断部２７は、端子部２５、２６の主面に接続されていてもよいし、上面に接続されていてもよい。 The fusing part 27 is narrower than the terminal parts 25 and 26 and is easily blown by Joule heat when an overcurrent flows. The fusing part 27 is integrally formed with the pair of terminal parts 25 and 26. In the example shown in FIG. 4, the fusing part 27 is connected to the side surfaces of the terminal parts 25 and 26, but the connection position between the fusing part 27 and the terminal parts 25 and 26 is not limited to the above. For example, the fusing part 27 may be connected to the main surfaces of the terminal parts 25 and 26 or may be connected to the upper surface.
　ケース２８は、直方体状に形成され、ヒューズエレメント２４のうち溶断部２７及び端子部２５、２６のうち基端側を収容する。例えば、ケース２８は、ヒューズエレメント２４の周囲に樹脂等の絶縁材料をモールド成型することによって得られる。 The case 28 is formed in a rectangular parallelepiped shape and accommodates the base end side of the fusing portion 27 and the terminal portions 25 and 26 of the fuse element 24. For example, the case 28 is obtained by molding an insulating material such as resin around the fuse element 24.
　バスバ３０は、ヒューズ２２と金属板１４とを接続する。具体的には、バスバ３０は、ヒューズ接続部３２と当接部３４とを含む。かかる当接部３４が上記電気接続部２１において金属板１４と接続される上記金属板側接続部の一例である。 The bus bar 30 connects the fuse 22 and the metal plate 14. Specifically, the bus bar 30 includes a fuse connection portion 32 and a contact portion 34. The contact portion 34 is an example of the metal plate side connection portion that is connected to the metal plate 14 in the electrical connection portion 21.
　ヒューズ接続部３２は、ヒューズ２２の一端側端子部２５が接続される。ここでは、ヒューズ接続部３２は、相手方のタブ端子が圧入されるスロット３３が切り込まれた形状に形成されている。このようなヒューズ接続部３２の形状は、音叉端子とも呼ばれる。もっとも、ヒューズ接続部３２は、外部導体としての端子７４のように、底部の幅方向両縁に立設された係止片が底部に向けて折り返された形状、いわゆる雌端子状に形成されたものであってもよい。 The fuse connection portion 32 is connected to the one end side terminal portion 25 of the fuse 22. Here, the fuse connecting portion 32 is formed in a shape in which a slot 33 into which a mating tab terminal is press-fitted is cut. Such a shape of the fuse connection portion 32 is also called a tuning fork terminal. However, the fuse connecting portion 32 is formed in a so-called female terminal shape in which locking pieces erected on both edges in the width direction of the bottom portion are folded back toward the bottom portion, like a terminal 74 as an external conductor. It may be a thing.
　当接部３４は、平板状に形成されている。当接部３４は、金属板１４の主面１５に面接触して接続可能である。ここでは、当接部３４が間隔をあけて一対設けられている。一対の当接部３４は、例えば、金属板１４の厚みと同程度の間隔をあけている。このため、一対の当接部３４が金属板１４の相互に反対側を向く２つの主面１５ａ、１５ｂに当接可能である。一対の当接部３４は、基端側で連結部３６によって連結されている。ここでは、１つの当接部３４に対して複数のヒューズ接続部３２が設けられるものとして説明するが、このことは必須ではない。例えば、１つの当接部３４に対して１つのヒューズ接続部３２が設けられるものであってもよい。この場合、複数のヒューズ２２の数だけバスバが並列に設けられる。 The contact portion 34 is formed in a flat plate shape. The contact portion 34 can be connected in surface contact with the main surface 15 of the metal plate 14. Here, a pair of abutting portions 34 are provided at intervals. For example, the pair of contact portions 34 are spaced apart from each other by the same thickness as the metal plate 14. For this reason, a pair of contact part 34 can contact | abut to the two main surfaces 15a and 15b which face the mutually opposite side of the metal plate 14. FIG. The pair of contact portions 34 are connected by a connecting portion 36 on the base end side. Here, although it demonstrates as what is provided with the some fuse connection part 32 with respect to one contact part 34, this is not essential. For example, one fuse connection portion 32 may be provided for one contact portion 34. In this case, as many bus bars as the plurality of fuses 22 are provided in parallel.
　ここで、バスバ３０は、一枚の平板に打抜き加工及び折り曲げ加工などが施されて形成されることが考えられる。この際、当接部３４又は連結部３６の一部を切り起こすなどして、ヒューズ接続部３２を形成することが考えられる。図４に示す例では、連結部３６を切り起こしてヒューズ接続部３２を形成している。もっとも、ヒューズ接続部３２は、平板の端部等に設けられるものであってもよい。例えば、当接部３４又は連結部３６から枝分かれさせることで、平板の端部にヒューズ接続部３２を設けることが可能である。 Here, it is conceivable that the bus bar 30 is formed by punching or bending a single flat plate. At this time, it is conceivable to form the fuse connection portion 32 by cutting up a part of the contact portion 34 or the connecting portion 36. In the example shown in FIG. 4, the connecting portion 36 is cut and raised to form the fuse connecting portion 32. But the fuse connection part 32 may be provided in the edge part etc. of a flat plate. For example, it is possible to provide the fuse connecting portion 32 at the end portion of the flat plate by branching from the contact portion 34 or the connecting portion 36.
　中継端子４０は、複数のヒューズ２２の他端側にそれぞれ連なる。中継端子４０は、外部導体としての端子７４と接続される。ここでは、中継端子４０は、ヒューズ２２とは別体に設けられている。具体的には、中継端子４０は、ヒューズ接続部４２と外部導体側接続部４４とを含む。 The relay terminal 40 is connected to the other end of each of the plurality of fuses 22. The relay terminal 40 is connected to a terminal 74 as an external conductor. Here, the relay terminal 40 is provided separately from the fuse 22. Specifically, the relay terminal 40 includes a fuse connection portion 42 and an external conductor side connection portion 44.
　図４に示す例では、中継端子４０のヒューズ接続部４２は、バスバ３０のヒューズ接続部３２と同様に、スロット４３が形成された音叉端子状に形成されている。一方、外部導体側接続部４４は、タブ端子状に形成されている。ヒューズ接続部４２と外部導体側接続部４４とは、それぞれの基端側で連結部４６を介して連なっている。 In the example shown in FIG. 4, the fuse connection portion 42 of the relay terminal 40 is formed in the shape of a tuning fork terminal in which a slot 43 is formed, like the fuse connection portion 32 of the bus bar 30. On the other hand, the outer conductor side connecting portion 44 is formed in a tab terminal shape. The fuse connecting portion 42 and the external conductor side connecting portion 44 are connected to each other through the connecting portion 46 on the base end side.
　ハウジング５０は、絶縁材料で形成されている。ハウジング５０は、金属板側接続部の接続点を電線１２と接続可能な態様で且つ外部導体側接続部を外部導体と接続可能な態様で露出させつつ電気接続部２１を保持する。ここでは、ハウジング５０は、当接部３４の当接面を電線１２と接続可能な態様で且つ中継端子４０を外部導体としての端子７４と接続可能な態様で露出させつつバスバ３０及び中継端子４０を保持する。ここでは、ハウジング５０は、ヒューズ２２をさらに保持する。具体的には、ハウジング５０は、第１部分５２と、第２部分５４と、第３部分５６とを含む。 The housing 50 is made of an insulating material. The housing 50 holds the electrical connection portion 21 while exposing the connection point of the metal plate side connection portion to the electric wire 12 and exposing the external conductor side connection portion to the external conductor. Here, the housing 50 exposes the bus bar 30 and the relay terminal 40 while exposing the contact surface of the contact portion 34 to the wire 12 and exposing the relay terminal 40 to the terminal 74 as the external conductor. Hold. Here, the housing 50 further holds the fuse 22. Specifically, the housing 50 includes a first portion 52, a second portion 54, and a third portion 56.
　第１部分５２は、バスバ３０の当接部３４及び連結部３６が収まる部分である。第１部分５２の内周面は、当接部３４及び連結部３６の外周面に沿った形状に形成されている。そして、その内周面の形状（ここでは、横断面Ｕ字状）が電線１２の延在方向に連続する形状を呈する。一対の当接部３４は、相互に相手側を向く主面３５が露出する態様で第１部分５２に収まる。このため、第１部分５２内の一対の当接部３４間に金属板１４を挿し込み可能とされている。 The first portion 52 is a portion in which the abutting portion 34 and the connecting portion 36 of the bus bar 30 are accommodated. The inner peripheral surface of the first portion 52 is formed in a shape along the outer peripheral surfaces of the contact portion 34 and the connecting portion 36. And the shape (here U-shaped cross section) of the internal peripheral surface exhibits the shape which continues in the extension direction of the electric wire 12. FIG. A pair of contact part 34 is settled in the 1st part 52 in the aspect in which the main surface 35 which faces the other party mutually is exposed. For this reason, the metal plate 14 can be inserted between the pair of contact portions 34 in the first portion 52.
　第２部分５４は、バスバ３０のヒューズ接続部３２、中継端子４０のヒューズ接続部４２及びヒューズ２２が収まる部分である。ここでは、第２部分５４には、側面視で長方形の穴５５が形成されている。穴５５は、有底であり、底５５ａの部分は第１部分５２との仕切となっている。また、底５５ａの部分にヒューズ接続部３２の基端部が通過可能な孔５５ｂが形成されている。これにより、ヒューズ接続部３２のスロット３３が穴５５内に突出している。また、穴５５の内周側部５５ｃのうち下方の部分は、第３部分５６の後述する穴５７（キャビティ６０）との仕切となっている。この内周側部５５ｃの下方の部分に孔５５ｄが形成されている。孔５５ｄには、中継端子４０の連結部４６が挿通され、中継端子４０のヒューズ接続部４２が穴５５内に突出可能となっている。そして、穴５５内においてヒューズ２２の一端側端子部２５がバスバ３０のヒューズ接続部３２のスロット３３に圧入接続されると共に、ヒューズ２２の他端側端子部２６が中継端子４０のヒューズ接続部４２のスロット４３に圧入接続される。この際、ヒューズ２２は、バスバ３０及び中継端子４０を介してハウジング５０に保持される。従って、ヒューズ２２はスロット３３、４３から抜くことでハウジング５０から外すことが可能となっており、これによりヒューズ２２は切れた際などに交換可能となっている。もっとも、ヒューズ２２はハウジング５０に埋設されるなどして交換不能であってもよい。この場合は、ヒューズ２２が切れた場合、電気接続部品２０ごと交換することが考えられる。 The second portion 54 is a portion in which the fuse connection portion 32 of the bus bar 30, the fuse connection portion 42 of the relay terminal 40, and the fuse 22 are accommodated. Here, a rectangular hole 55 is formed in the second portion 54 in a side view. The hole 55 has a bottom, and a portion of the bottom 55 a is a partition with the first portion 52. Further, a hole 55b through which the base end portion of the fuse connecting portion 32 can pass is formed in the bottom 55a. As a result, the slot 33 of the fuse connecting portion 32 protrudes into the hole 55. Further, the lower portion of the inner peripheral side portion 55 c of the hole 55 serves as a partition with a hole 57 (cavity 60) described later of the third portion 56. A hole 55d is formed in a portion below the inner peripheral side portion 55c. The connecting portion 46 of the relay terminal 40 is inserted into the hole 55 d so that the fuse connecting portion 42 of the relay terminal 40 can protrude into the hole 55. In the hole 55, the one end side terminal portion 25 of the fuse 22 is press-fitted and connected to the slot 33 of the fuse connection portion 32 of the bus bar 30, and the other end side terminal portion 26 of the fuse 22 is connected to the fuse connection portion 42 of the relay terminal 40. Are press-fitted into the slots 43 of At this time, the fuse 22 is held in the housing 50 via the bus bar 30 and the relay terminal 40. Therefore, the fuse 22 can be removed from the housing 50 by being pulled out of the slots 33 and 43, so that the fuse 22 can be replaced when it is blown. However, the fuse 22 may be non-replaceable by being embedded in the housing 50. In this case, when the fuse 22 is blown, it is conceivable to replace the electrical connection component 20 together.
　第３部分５６は、中継端子４０の外部導体側接続部４４及びこれに接続される外部導体としての端子７４が収められる部分である。ここで電気接続部品２０には、キャビティ６０が形成されている。キャビティ６０には、中継端子４０のうちヒューズ２２と接続される側とは反対側部分及びこれに接続される外部導体としての端子７４を収容可能である。ここでは、ハウジング５０の第３部分５６に形成された穴５７が上記キャビティ６０として機能する。 The third portion 56 is a portion in which the external conductor side connection portion 44 of the relay terminal 40 and the terminal 74 as an external conductor connected thereto are accommodated. Here, a cavity 60 is formed in the electrical connection component 20. The cavity 60 can accommodate a portion of the relay terminal 40 opposite to the side connected to the fuse 22 and a terminal 74 as an external conductor connected thereto. Here, the hole 57 formed in the third portion 56 of the housing 50 functions as the cavity 60.
　上述したようにここでは、外部導体として端子付電線７０における端子７４が想定されている。端子付電線７０は、電線７２の端部に端子７４が設けられている。電線７２と端子７４とは、電線７２端部の芯線露出部が端子７４に対して圧着又は溶接等されることによって接続される。上述したように、ここでは端子７４は、中継端子４０のタブ状の外部導体側接続部４４と接続可能な雌端子状に形成されている。従って、キャビティ６０は、この雌端子状の端子７４を収容可能な大きさに形成される。 As described above, here, the terminal 74 in the terminal-attached electric wire 70 is assumed as the outer conductor. The terminal-attached electric wire 70 is provided with a terminal 74 at the end of the electric wire 72. The electric wire 72 and the terminal 74 are connected by crimping or welding the core wire exposed portion at the end of the electric wire 72 to the terminal 74. As described above, the terminal 74 is formed in a female terminal shape that can be connected to the tab-shaped outer conductor side connection portion 44 of the relay terminal 40 here. Accordingly, the cavity 60 is formed in a size that can accommodate the female terminal-like terminal 74.
　ハウジング５０は、例えば、バスバ３０及び中継端子４０の少なくとも一方の周囲に樹脂等の絶縁材料をモールド成型することによって得られる。もっとも、ハウジング５０は、バスバ３０及び中継端子４０とは別体に成型された成型品であってもよい。この場合、ハウジング５０には、バスバ３０及び中継端子４０をそれぞれ係止可能な係止手段が形成されているとよい。 The housing 50 is obtained, for example, by molding an insulating material such as resin around at least one of the bus bar 30 and the relay terminal 40. However, the housing 50 may be a molded product molded separately from the bus bar 30 and the relay terminal 40. In this case, the housing 50 may be formed with locking means capable of locking the bus bar 30 and the relay terminal 40 respectively.
　また、ここでは、電気接続部品２０は、電線１２に対して一対の当接部３４が金属板１４を挟み込むことによって位置決め固定されている。もっとも、電線１２に対する電気接続部品２０の取付構造は上記したものに限られない。例えば、電気接続部品２０は、図示省略の係止構造等によって、電線１２に対して位置決め固定されているものであってもよい。 Further, here, the electrical connecting component 20 is positioned and fixed by the pair of abutting portions 34 sandwiching the metal plate 14 with respect to the electric wire 12. But the attachment structure of the electrical connection component 20 with respect to the electric wire 12 is not restricted to what was mentioned above. For example, the electrical connection component 20 may be positioned and fixed with respect to the electric wire 12 by a locking structure (not shown) or the like.
　上記のように構成された電気接続部品２０及びこれを備えるワイヤーハーネス１０によると、外部導体側接続部を有する電気接続部品２０を、偏平な金属板１４の延在方向に沿ったいずれの部分に対しても接続容易となる。これにより、電気接続部品２０を介して、外部導体を、偏平な金属板１４の延在方向に沿ったいずれの部分に対しても容易に接続可能にすることができる。特にここでは、当接部３４が金属板１４の主面に当接して入力された電源を、ヒューズ２２及び中継端子４０を介して容易に分配することができる。当接部３４は、金属板１４の延在方向に沿ったいずれの部分にも当接可能である。従って、電気接続部品２０は、金属板１４の延在方向に沿ったいずれの部分からでも容易に電源を分配可能である。 According to the electrical connection component 20 configured as described above and the wire harness 10 including the electrical connection component 20, the electrical connection component 20 having the outer conductor side connection portion is placed on any portion along the extending direction of the flat metal plate 14. Connection is also easy. Thereby, the external conductor can be easily connected to any portion along the extending direction of the flat metal plate 14 via the electrical connection component 20. In particular, here, the power that is input with the contact portion 34 in contact with the main surface of the metal plate 14 can be easily distributed via the fuse 22 and the relay terminal 40. The abutting portion 34 can abut on any portion along the extending direction of the metal plate 14. Therefore, the electrical connection component 20 can easily distribute the power from any part along the extending direction of the metal plate 14.
　また、一対の当接部３４がそれぞれ金属板１４と接続されるため、接続状態が安定する。この際、一対の当接部３４が金属板１４を挟み込むことで、電気接続部品２０と金属板１４との位置決め固定が図られる。また、当接部３４が金属板１４と面接触しているため、これらの接続部分において断面積を大きくできる。 In addition, since the pair of contact portions 34 are connected to the metal plate 14, the connection state is stabilized. At this time, the pair of contact portions 34 sandwich the metal plate 14 so that the electrical connection component 20 and the metal plate 14 are positioned and fixed. Further, since the contact portion 34 is in surface contact with the metal plate 14, the cross-sectional area can be increased at these connection portions.
　また、ハウジング５０にキャビティ６０が形成されているため、キャビティ６０に外部導体と接続可能な端子（ここでは中継端子４０）を設けておくことで、当該電気接続部品２０に、例えば、端子付電線７０などの外部導体を容易に接続することができる。 Further, since the cavity 60 is formed in the housing 50, by providing a terminal (here, the relay terminal 40) that can be connected to the external conductor in the cavity 60, for example, an electric wire with a terminal is provided in the electrical connection component 20. An external conductor such as 70 can be easily connected.
　｛第１実施形態の変形例｝
　第１実施形態において、電気接続部品２０が電線１２における被覆１６が皮剥ぎされた部分に接続されたものとして説明したが、このことは必須ではない。例えば、図５に示す第１変形例に係る電気接続部品１２０のように、電線１２における被覆１６を備える部分に接続されるものであってもよい。 {Modification of the first embodiment}
In 1st Embodiment, although the electrical-connection component 20 demonstrated as what was connected to the part by which the coating | coated 16 in the electric wire 12 was peeled, this is not essential. For example, like the electrical connection component 120 according to the first modification shown in FIG. 5, it may be connected to a portion of the electric wire 12 that includes the coating 16.
　より詳細には、バスバ１３０の当接部１３４の先端が先細りの形状に形成され、電線１２の被覆１６を貫通して金属板１４に当接可能に形成されている。この際、ハウジング１５０のうち当接部１３４の外側に位置する部分は省略可能である。 More specifically, the tip of the abutting portion 134 of the bus bar 130 is formed in a tapered shape so as to be able to abut against the metal plate 14 through the coating 16 of the electric wire 12. At this time, a portion of the housing 150 located outside the contact portion 134 can be omitted.
　このような電気接続部品１２０によると、電線１２の被覆１６を皮剥ぎせずとも当該電気接続部品１２０を接続できる。 According to such an electrical connection component 120, the electrical connection component 120 can be connected without peeling off the coating 16 of the electric wire 12.
　また、第１実施形態において、当接部３４が金属板１４を挟み込み可能に一対設けられているものとして説明したが、このことは必須ではない。例えば、図６に示す第２変形例に係る電気接続部品２２０のように、バスバ２３０に当接部１３４が１つのみ設けられ、バスバ２３０が金属板１４の一方主面１５にのみ当接するように設けられていてもよい。なお、図６に示す例では、電気接続部品２２０は、図５に示す電気接続部品１２０から一方の当接部１３４を省略した形状に形成されているが、当然図１に示す電気接続部品２０から一方の当接部３４を省略した形状に形成されていてもよい。 In the first embodiment, a pair of contact portions 34 are provided so as to be able to sandwich the metal plate 14, but this is not essential. For example, like the electrical connection component 220 according to the second modification shown in FIG. 6, only one contact portion 134 is provided on the bus bar 230 so that the bus bar 230 contacts only one main surface 15 of the metal plate 14. May be provided. In the example illustrated in FIG. 6, the electrical connection component 220 is formed in a shape in which one contact portion 134 is omitted from the electrical connection component 120 illustrated in FIG. 5, but naturally the electrical connection component 20 illustrated in FIG. 1. The one contact portion 34 may be omitted from the shape.
　また、第１実施形態において、ワイヤーハーネス１０が電線１２を１つ備えるものとして説明したが、このことは必須ではない。例えば、図７に示す変形例に係るワイヤーハーネス３１０のように、複数の電線１２を備えるものであってもよい。この場合、複数の電線１２は、薄手方向に並ぶように設けられるとよい。そして、図７に示す例では、複数の電線１２それぞれに対して、別の電気接続部品２０が接続されている。もっとも、複数の電線１２に対して１つの電気接続部品が一括して接続されている場合も考えられる。このように複数の電線１２に一括して接続可能な電気接続部品の例を図８に示す。 In the first embodiment, the wire harness 10 has been described as including one electric wire 12, but this is not essential. For example, like the wire harness 310 which concerns on the modification shown in FIG. In this case, the plurality of electric wires 12 are preferably provided so as to be arranged in the thin direction. In the example shown in FIG. 7, another electrical connection component 20 is connected to each of the plurality of electric wires 12. But the case where one electrical connection component is collectively connected with respect to the some electric wire 12 is also considered. FIG. 8 shows an example of an electrical connection component that can be connected to the plurality of electric wires 12 at once.
　図８に示す第３変形例に係る電気接続部品４２０では、２つのバスバ３０が１つのハウジング４５０に保持されている。従って、ハウジング４５０は２つの第１部分５２を含んだ形状に形成されている。２つのバスバ３０は、それぞれの当接部３４が金属板１４との当接方向に並ぶように設けられている。各バスバ３０に対して、第１実施形態に係る電気接続部品２０と同様に、ヒューズ２２及び中継端子４０が複数接続されている。従って、ハウジング４５０には２つのバスバ３０にそれぞれ接続されるヒューズ２２及び中継端子４０を収める第２部分５４及び第３部分５６が形成されている。図８に示す例では、一方のバスバ３０に接続されるヒューズ２２及び中継端子４０を収める第２部分５４及び第３部分５６の下方に、他方のバスバ３０に接続されるヒューズ２２及び中継端子４０を収める第２部分５４及び第３部分５６が形成されている。このような電気接続部品４２０によると、１つの部品で、複数の電線１２に接続できる。 8, in the electrical connection component 420 according to the third modification, two bus bars 30 are held in one housing 450. Accordingly, the housing 450 is formed in a shape including the two first portions 52. The two bus bars 30 are provided so that the respective contact portions 34 are aligned in the contact direction with the metal plate 14. As with the electrical connection component 20 according to the first embodiment, a plurality of fuses 22 and relay terminals 40 are connected to each bus bar 30. Accordingly, the housing 450 is formed with a second portion 54 and a third portion 56 that house the fuse 22 and the relay terminal 40 respectively connected to the two bus bars 30. In the example shown in FIG. 8, the fuse 22 and the relay terminal 40 connected to the other bus bar 30 are provided below the second portion 54 and the third portion 56 for housing the fuse 22 and the relay terminal 40 connected to the one bus bar 30. A second portion 54 and a third portion 56 are formed. According to such an electrical connection component 420, it is possible to connect to the plurality of electric wires 12 with one component.
　また、これまでヒューズ２２とバスバ３０と中継端子４０が別体であるものとして説明してきたが、このことは必須ではない。ヒューズが直接外部導体と接続可能であってもよい。つまり、ヒューズに中継端子の機能が組み込まれていてもよい。この場合、例えば、図９に示すように、ヒューズ５２２の他端側端子部５２６が、端子付電線５７０の端子５７４と直接接続可能な形状に形成されている構成が考えられる。図９に示す例では、ヒューズ５２２の他端側端子部５２６が音叉端子状に形成され、端子付電線５７０の端子５７４がタブ端子状に形成されている。そして、ヒューズ５２２のケース５２８に端子５７４を挿入保持可能なキャビティ５６０が形成されている。この場合、ハウジングにキャビティ（第３部分）を設ける必要はない。また、この場合、一端側端子部２５がバスバ３０と接続する向きと、他端側端子部５２６が端子５７４と接続する向きとは相互に逆向きとなっている。また、例えば、図１０に示す電気接続部６２１のようにヒューズ６２２の機能とバスバ６３０の機能とを有する一体品であってもよい。この際、図９と同様に、ヒューズ６２２の他端側端子部６２６が端子７４と直接接続可能な形状に形成されていてもよい。もっとも、ヒューズ６２２は、第１実施形態と同様に中継端子４０を介して端子７４と接続するものであってもよい。図１０に示す例では、電気接続部６２１において、金属板側接続部と、ヒューズと、外部導体側接続部とが一体物である。このような電気接続部６２１は、例えば一の板材に対して、プレス加工、打ち抜き加工、曲げ加工等が施されて形成される。 In addition, the fuse 22, the bus bar 30, and the relay terminal 40 have been described so far, but this is not essential. The fuse may be directly connectable to the external conductor. That is, the function of the relay terminal may be incorporated in the fuse. In this case, for example, as illustrated in FIG. 9, a configuration in which the other end side terminal portion 526 of the fuse 522 is formed in a shape that can be directly connected to the terminal 574 of the terminal-attached electric wire 570 is conceivable. In the example shown in FIG. 9, the other end side terminal portion 526 of the fuse 522 is formed in a tuning fork terminal shape, and the terminal 574 of the terminal-attached electric wire 570 is formed in a tab terminal shape. A cavity 560 in which the terminal 574 can be inserted and held is formed in the case 528 of the fuse 522. In this case, it is not necessary to provide a cavity (third portion) in the housing. In this case, the direction in which the one end side terminal portion 25 is connected to the bus bar 30 and the direction in which the other end side terminal portion 526 is connected to the terminal 574 are opposite to each other. Further, for example, an integrated product having the function of the fuse 622 and the function of the bus bar 630 may be used as in the electrical connection portion 621 shown in FIG. At this time, similarly to FIG. 9, the terminal 626 on the other end side of the fuse 622 may be formed in a shape that can be directly connected to the terminal 74. However, the fuse 622 may be connected to the terminal 74 via the relay terminal 40 as in the first embodiment. In the example shown in FIG. 10, in the electrical connection portion 621, the metal plate side connection portion, the fuse, and the external conductor side connection portion are integrated. Such an electrical connection portion 621 is formed by, for example, pressing, punching, bending, or the like on one plate material.
　また、図１１に示す電気接続部品７２０のように、電気接続部品７２０が電線１２の全周を覆う場合もあり得る。図１１に示す電気接続部品７２０では、ハウジング７５０の第１部分７５２が電線１２の全周を覆っている。バスバ７３０の当接部７３４は、電線１２の幅方向全体に亘っている。バスバ７３０は、電線１２の全周を覆っていない。もっとも、バスバが電線１２の全周を覆う一方でハウジングが電線１２の全周を覆っていないものであってもよい。また、バスバとハウジングの両方が電線１２の全周を覆っていてもよい。 In addition, like the electrical connection component 720 illustrated in FIG. 11, the electrical connection component 720 may cover the entire circumference of the electric wire 12. In the electrical connection component 720 shown in FIG. 11, the first portion 752 of the housing 750 covers the entire circumference of the electric wire 12. The contact portion 734 of the bus bar 730 extends over the entire width direction of the electric wire 12. The bus bar 730 does not cover the entire circumference of the electric wire 12. However, the housing may not cover the entire circumference of the electric wire 12 while the bus bar covers the entire circumference of the electric wire 12. Further, both the bus bar and the housing may cover the entire circumference of the electric wire 12.
　電気接続部品７２０のように、電線１２の全周を覆う場合であって電線１２の中間部に接続される場合、周方向に分割可能に且つ合体可能な形状とされていることが好ましい。これにより、電気接続部品を電線１２の中間部に取付容易となる。このように周方向に分割可能に且つ合体可能な電気接続部品については、後述する第２実施形態で詳しく説明する。なお、電気接続部品が電線１２の全周を覆う場合であっても電線１２の端部に接続される場合には、周方向に分割可能に且つ合体可能な形状とされていなくても、ハウジング側面に電線１２端部を収容可能なキャビティが形成されていれば、取付容易となる。 As in the case of the electrical connection component 720, when the entire circumference of the electric wire 12 is covered and connected to the intermediate portion of the electric wire 12, it is preferable that the shape is separable in the circumferential direction and can be combined. Thereby, it becomes easy to attach the electrical connection component to the intermediate portion of the electric wire 12. The electrical connection parts that can be divided in the circumferential direction and can be combined will be described in detail in a second embodiment to be described later. Even when the electrical connection component covers the entire circumference of the electric wire 12, when it is connected to the end of the electric wire 12, the housing can be formed even if it is not formed into a shape that can be divided and combined in the circumferential direction. If a cavity capable of accommodating the end portion of the electric wire 12 is formed on the side surface, the attachment becomes easy.
　また、これまでヒューズ２２が電線１２に対して側方に位置するものとして説明してきたが、このことは必須ではない。例えば、ヒューズ２２は、電線１２に対して上方又は下方に位置するものであってもよい。また、１つの電線１２に対してバスバ３０を介して複数接続されるヒューズ２２が電線１２の長手方向に並ぶものとして説明してきたが、このことは必須ではない。例えば、複数のヒューズ２２は、電線１２の厚み方向又は幅方向に並ぶものであってもよい。上記は、中継端子についても同様である。 In the above description, it has been described that the fuse 22 is positioned laterally with respect to the electric wire 12, but this is not essential. For example, the fuse 22 may be located above or below the electric wire 12. Moreover, although it has been described that a plurality of fuses 22 connected to one electric wire 12 via the bus bar 30 are arranged in the longitudinal direction of the electric wire 12, this is not essential. For example, the plurality of fuses 22 may be arranged in the thickness direction or the width direction of the electric wire 12. The same applies to the relay terminal.
　また、これまで外部導体が端子付電線７０であるものとして説明したがこのことは必須ではない。例えば、外部導体として、複数の端子付電線７０がハウジングのキャビティに挿入接続されたコネクタが採用されてもよい。 In addition, although it has been described so far that the outer conductor is the terminal-attached electric wire 70, this is not essential. For example, a connector having a plurality of terminal-attached electric wires 70 inserted and connected to the cavity of the housing may be employed as the external conductor.
　｛第２実施形態｝
　以下、第２実施形態に係る電気接続部品及びこれを備えるワイヤーハーネスについて説明する。図１２は、第２実施形態に係る電気接続部品８２０及びこれを備えるワイヤーハーネス８１０を示す斜視図である。図１３は、第２実施形態に係る電気接続部品８２０を示す側面図である。図１４は、図１３のＸＩＶ－ＸＩＶ線に沿って切断した断面図である。なお、本実施の形態の説明において、これまで説明したものと同様構成要素については同一符号を付してその説明を省略する。 {Second Embodiment}
Hereinafter, the electrical connection component according to the second embodiment and the wire harness including the electrical connection component will be described. FIG. 12 is a perspective view showing an electrical connection component 820 and a wire harness 810 including the electrical connection component 820 according to the second embodiment. FIG. 13 is a side view showing an electrical connection component 820 according to the second embodiment. 14 is a cross-sectional view taken along line XIV-XIV in FIG. In the description of the present embodiment, the same components as those described above are denoted by the same reference numerals, and the description thereof is omitted.
　本実施形態に係るワイヤーハーネス８１０は、電気接続部品２０に替えて電気接続部品８２０を備えている。本実施形態は、外部導体がコネクタ８７０におけるコネクタ端子８７５である事例である。従って、電気接続部品８２０は、コネクタ８７０と接続可能に形成されている点で、第１実施形態に係る電気接続部品２０とは異なる。 The wire harness 810 according to the present embodiment includes an electrical connection component 820 instead of the electrical connection component 20. This embodiment is an example in which the outer conductor is the connector terminal 875 in the connector 870. Therefore, the electrical connection component 820 is different from the electrical connection component 20 according to the first embodiment in that the electrical connection component 820 is formed to be connectable to the connector 870.
　さらにここでは電気接続部品８２０は、ヒューズを備えていない点で、第１実施形態に係る電気接続部品２０とは異なる。もっとも、電気接続部品８２０は、第１実施形態に係る電気接続部品２０のように、ヒューズを備えていてもよい。 Furthermore, here, the electrical connection component 820 is different from the electrical connection component 20 according to the first embodiment in that it does not include a fuse. But the electrical connection component 820 may be equipped with the fuse like the electrical connection component 20 which concerns on 1st Embodiment.
　電気接続部品８２０のバスバ８３０は、金属板１４とコネクタ８７０のコネクタ端子８７５とを接続する。具体的には、バスバ８３０は、コネクタ接続部８３２と当接部８３４とを含む。 The bus bar 830 of the electrical connection component 820 connects the metal plate 14 and the connector terminal 875 of the connector 870. Specifically, the bus bar 830 includes a connector connecting portion 832 and a contact portion 834.
　コネクタ接続部８３２は、少なくとも１つの端子部８３３を含む。図１２に示す例では、３つの端子部８３３が設けられている。各端子部８３３は、コネクタ８７０に収められたコネクタ端子８７５とそれぞれ接続可能である。なお、ここでは、１つの当接部８３４に対して複数の端子部８３３が設けられるものとして説明するが、このことは必須ではない。例えば、１つの当接部８３４に対して１つの端子部８３３が設けられるものであってもよい。この場合、複数のコネクタ端子８７５の数だけバスバが並列に設けられる。 The connector connecting portion 832 includes at least one terminal portion 833. In the example shown in FIG. 12, three terminal portions 833 are provided. Each terminal portion 833 can be connected to a connector terminal 875 housed in the connector 870. In addition, although demonstrated here that the some terminal part 833 is provided with respect to one contact part 834, this is not essential. For example, one terminal portion 833 may be provided for one abutting portion 834. In this case, the bus bars are provided in parallel by the number of the plurality of connector terminals 875.
　当接部８３４は、平板状に形成されている。当接部８３４は、金属板１４の主面１５に面接触して接続可能である。ここでは、当接部８３４は１つのみ設けられ、金属板１４の一方の主面１５に当接している。バスバ８３０は、当接部８３４の基端側で折り曲げられて連結部８３６に連なっている。ここでは、連結部８３６にコネクタ接続部８３２が設けられている。 The contact portion 834 is formed in a flat plate shape. The contact portion 834 can be connected in surface contact with the main surface 15 of the metal plate 14. Here, only one abutting portion 834 is provided and abuts against one main surface 15 of the metal plate 14. The bus bar 830 is bent at the base end side of the abutting portion 834 and continues to the connecting portion 836. Here, a connector connecting portion 832 is provided in the connecting portion 836.
　ここで、バスバ８３０は、一枚の平板に打抜き加工及び折り曲げ加工などが施されて形成されることが考えられる。この際、当接部８３４又は連結部８３６の一部を切り起こすなどして、端子部８３３を形成するものであってもよいし、当接部８３４又は連結部８３６から枝分かれさせることで、平板の端部に端子部８３３を設けるものであってもよい。 Here, it is conceivable that the bus bar 830 is formed by punching or bending a single flat plate. At this time, the terminal portion 833 may be formed by raising a part of the abutting portion 834 or the connecting portion 836, or by branching from the abutting portion 834 or the connecting portion 836. A terminal portion 833 may be provided at the end of the terminal.
　電気接続部品８２０におけるハウジング８５０は、当接部８３４の当接面を電線１２と接続可能な態様で且つ端子部８３３をコネクタ８７０のコネクタ端子８７５と接続可能な態様で露出させつつバスバ８３０を保持する。ハウジング８５０は、第１収容部８５２と、第２収容部８５３とを有するハウジング本体８５１を含む。ハウジング本体８５１にはコネクタ８７０を挿入保持可能なキャビティ８５４が形成されている。 The housing 850 in the electrical connection component 820 holds the bus bar 830 while exposing the contact surface of the contact portion 834 in a form that can be connected to the electric wire 12 and the terminal portion 833 in a form that can be connected to the connector terminal 875 of the connector 870. To do. The housing 850 includes a housing body 851 having a first housing portion 852 and a second housing portion 853. A cavity 854 into which the connector 870 can be inserted and held is formed in the housing main body 851.
　第１収容部８５２は、バスバ８３０の当接部８３４及び連結部８３６が収まる部分である。ここでは第１収容部８５２は、金属板１４の全周を囲繞可能に形成されている。つまり、第１収容部８５２は、筒状に形成され、その軸心方向が電線１２の延在方向に沿った方向となっている。当接部８３４は、連結部８３６との折り曲げ形状に関し内周側になる主面が筒の内側を向く態様で第１収容部８５２に収まる。このため、連結部８３６の内向き面が金属板１４の側面に当接している。なお、第１収容部８５２は、バスバ８３０を金属板１４に向けて押しつけ可能な寸法又は形状を有するように形成されているとよい。 The 1st accommodating part 852 is a part in which the contact part 834 and the connection part 836 of the bus bar 830 are settled. Here, the 1st accommodating part 852 is formed so that the perimeter of the metal plate 14 can be enclosed. That is, the 1st accommodating part 852 is formed in a cylinder shape, and the axial center direction has become the direction along the extension direction of the electric wire 12. FIG. The abutting portion 834 is accommodated in the first accommodating portion 852 in such a manner that the main surface on the inner peripheral side in the bent shape with the connecting portion 836 faces the inside of the cylinder. For this reason, the inward surface of the connection part 836 is in contact with the side surface of the metal plate 14. In addition, the 1st accommodating part 852 is good to be formed so that it may have the dimension or shape which can press the bus bar 830 toward the metal plate 14. FIG.
　第２収容部８５３は、バスバ８３０のコネクタ接続部８３２、及びコネクタ８７０が収まる部分である。ここでは、第２収容部８５３には、側面視で長方形のキャビティ８５４が形成されている。キャビティ８５４は、有底であり、底８５５ａの部分は第１収容部８５２との仕切となっている。また、底８５５ａの部分に端子部８３３の基端部が通過可能な孔８５５ｂが形成されている。これにより、端子部８３３の先端がキャビティ８５４内に突出している。そして、キャビティ８５４内においてバスバ８３０の各端子部８３３がキャビティ８５４内に収まったコネクタ８７０のコネクタ端子８７５に接続されている。 The second accommodating portion 853 is a portion in which the connector connecting portion 832 and the connector 870 of the bus bar 830 are accommodated. Here, a rectangular cavity 854 is formed in the second housing portion 853 in a side view. The cavity 854 has a bottom, and a portion of the bottom 855a is a partition with the first accommodating portion 852. Further, a hole 855b through which the base end portion of the terminal portion 833 can pass is formed in the bottom 855a. As a result, the tip of the terminal portion 833 protrudes into the cavity 854. In the cavity 854, each terminal portion 833 of the bus bar 830 is connected to the connector terminal 875 of the connector 870 that is accommodated in the cavity 854.
　特にここでは、ハウジング８５０は、当該第１収容部８５２を２分する態様で、第１合体部分８５６と第２合体部分８５７とで構成される。第１合体部分８５６は、第１収容部８５２の一部と、第２収容部８５３を含む。第１合体部分８５６における第１収容部８５２は、横断面Ｕ字状に形成され、これが電線１２の延在方向に連続する形状を呈する。第２合体部分８５７は、第１収容部８５２の一部を含む。ここでは、第２合体部分８５７は、Ｕ字状の第１合体部分８５６の蓋を成している。 Particularly here, the housing 850 is composed of a first combined portion 856 and a second combined portion 857 in such a manner that the first accommodating portion 852 is divided into two. The first combined portion 856 includes a part of the first storage portion 852 and the second storage portion 853. The 1st accommodating part 852 in the 1st union part 856 is formed in the cross-sectional U shape, and this exhibits the shape which continues in the extension direction of the electric wire 12. FIG. The second combined portion 857 includes a part of the first housing portion 852. Here, the second merged portion 857 forms a lid for the U-shaped first merged portion 856.
　ここでは、第１合体部分８５６と第２合体部分８５７とは、凸部８５８と凹部８５９との嵌め合い構造により合体可能とされている。図１４に示す例では、凸部８５８が第１合体部分８５６に形成され、凹部８５９が第２合体部分８５７に形成され散るが、逆であってもよい。この際、凸部８５８と凹部８５９とは金属板１４の幅方向に沿って嵌り合うように形成されている。もっとも、第１合体部分８５６と第２合体部分８５７との合体を可能にする構造は、上記したものに限られない。例えば、第１合体部分８５６及び第２合体部分８５７の対応する位置にネジ穴が形成され、当該ネジ穴にネジを螺合することによって、第１合体部分８５６及び第２合体部分８５７を合体するものであってもよい。また、第１合体部分８５６と第２合体部分８５７とが凸部８５８と凹部８５９との嵌めあい構造によって合体する場合でも、その嵌めあい構造は上記したものに限られない。例えば、凸部８５８と凹部８５９とが金属板８１４の厚み方向又は延在方向に沿って嵌り合うように形成されていてもよい。 Here, the first combined portion 856 and the second combined portion 857 can be combined by a fitting structure of the convex portion 858 and the concave portion 859. In the example shown in FIG. 14, the convex portion 858 is formed in the first combined portion 856 and the concave portion 859 is formed and scattered in the second combined portion 857, but the reverse may be possible. At this time, the convex portion 858 and the concave portion 859 are formed to fit along the width direction of the metal plate 14. However, the structure that enables the first merged portion 856 and the second merged portion 857 to be merged is not limited to the above. For example, screw holes are formed at corresponding positions of the first combined portion 856 and the second combined portion 857, and the first combined portion 856 and the second combined portion 857 are combined by screwing screws into the screw holes. It may be a thing. Further, even when the first combined portion 856 and the second combined portion 857 are combined by the fitting structure of the convex portion 858 and the concave portion 859, the fitting structure is not limited to the above. For example, the convex portion 858 and the concave portion 859 may be formed so as to fit along the thickness direction or the extending direction of the metal plate 814.
　ハウジング８５０の第１合体部分８５６及び第２合体部分８５７は、例えば、バスバ８３０とは別体に成型された成型品であることが考えられる。この場合、第１合体部分８５６には、バスバ８３０を係止可能な係止手段が形成されているとよい。ここでは、第１合体部分８５６の第１収容部８５２にバスバ８３０が嵌る凹み８５７ａが形成されている。もっとも、第１合体部分８５６は、バスバ８３０の周囲に樹脂等の絶縁材料をモールド成型することによって形成されるものであってもよい。この場合、樹脂材料とバスバとが接合するため、係止構造は不要とされる。 The first combined portion 856 and the second combined portion 857 of the housing 850 are considered to be molded products formed separately from the bus bar 830, for example. In this case, the first combined portion 856 may be formed with locking means that can lock the bus bar 830. Here, a recess 857 a into which the bus bar 830 is fitted is formed in the first housing portion 852 of the first combined portion 856. However, the first combined portion 856 may be formed by molding an insulating material such as resin around the bus bar 830. In this case, since the resin material and the bus bar are joined, the locking structure is unnecessary.
　コネクタ８７０は、コネクタハウジング８７２と、コネクタハウジング８７２に形成されたキャビティ８７３に挿入接続されているコネクタ端子８７５とを含む。コネクタ端子８７５は、例えば、電線８７６の端部の芯線露出部に圧着、圧接又は溶接等により接続されて端子付電線８７４の一部をなしている。もっとも、当該コネクタ端子８７５が電線８７６と直接接続されない中継端子等で構成されている場合もあり得る。コネクタ端子８７５は、少なくとも１つ含まれていればよい。図１２に示す例では、３本の端子付電線８７４が１つのコネクタハウジング８７２に挿入接続されている。なお、コネクタハウジング８７２に形成されたすべてのキャビティ８５４にコネクタ端子８７５が挿入接続されることは必須ではなく、コネクタ８７０においてコネクタ端子８７５が挿入接続されていないキャビティ８５４が存在していてもよい。ここでは端子部８３３がタブ状のオス端子形状に形成されているため、コネクタ端子８７５は当該オス端子と接続可能なメス端子形状に形成されている。かかるメス端子形状としては、例えば、底部の幅方向両縁に立設された係止片が底部に向けて折り返された形状、又は箱部に孔が開けられた形状等が考えられる。 The connector 870 includes a connector housing 872 and connector terminals 875 inserted and connected to a cavity 873 formed in the connector housing 872. For example, the connector terminal 875 is connected to the core wire exposed portion at the end of the electric wire 876 by crimping, pressure welding, welding, or the like and forms a part of the electric wire 874 with terminal. However, the connector terminal 875 may be configured by a relay terminal or the like that is not directly connected to the electric wire 876. At least one connector terminal 875 may be included. In the example shown in FIG. 12, three electric wires with terminals 874 are inserted and connected to one connector housing 872. It is not essential that the connector terminals 875 are inserted and connected to all the cavities 854 formed in the connector housing 872, and there may be cavities 854 in the connector 870 to which the connector terminals 875 are not inserted and connected. Here, since the terminal portion 833 is formed in a tab-shaped male terminal shape, the connector terminal 875 is formed in a female terminal shape that can be connected to the male terminal. As the shape of the female terminal, for example, a shape in which locking pieces erected on both edges in the width direction of the bottom portion are folded back toward the bottom portion, a shape in which a hole is formed in the box portion, or the like can be considered.
　上記電気接続部品８２０及びこれを備えるワイヤーハーネス８１０によると、ハウジング８５０に挿入保持されるコネクタ８７０が、ハウジング８５０に保持されるバスバ８３０の端子部８３３及び当接部８３４を介して金属板１４と接続可能である。この際、当接部８３４は、金属板１４の延在方向に沿ったいずれの部分にも当接可能である。従って、電気接続部品８２０を金属板１４に接続することによって、金属板１４の延在方向に沿ったいずれの部分にも容易にコネクタ８７０を接続可能である。この際、端子部８３３とコネクタ端子８７５との接続を介して金属板１４と外部導体とが接続されるため、外部導体を容易に金属板１４に接続させることができる。 According to the electrical connection component 820 and the wire harness 810 including the electrical connection component 820, the connector 870 inserted and held in the housing 850 is connected to the metal plate 14 via the terminal portion 833 and the contact portion 834 of the bus bar 830 held in the housing 850. Connectable. At this time, the contact part 834 can contact any part along the extending direction of the metal plate 14. Therefore, by connecting the electrical connection component 820 to the metal plate 14, the connector 870 can be easily connected to any portion along the extending direction of the metal plate 14. At this time, since the metal plate 14 and the external conductor are connected via the connection between the terminal portion 833 and the connector terminal 875, the external conductor can be easily connected to the metal plate 14.
　また、第１合体部分８５６と第２合体部分８５７との合体が解除された状態で電気接続部品８２０の内部に金属板１４を挿通させることができる。これにより、電気接続部品８２０を金属板１４に取付容易となる。また、第１合体部分８５６と第２合体部分８５７とが合体した状態で、金属板１４の全周を囲繞可能であるため、電気接続部品８２０と金属板１４とに位置ずれ等が生じにくい。 In addition, the metal plate 14 can be inserted into the electrical connection component 820 in a state where the merge of the first merged portion 856 and the second merged portion 857 is released. Thereby, the electrical connection component 820 can be easily attached to the metal plate 14. In addition, since the entire circumference of the metal plate 14 can be surrounded in a state where the first merged portion 856 and the second merged portion 857 are merged, misalignment or the like hardly occurs between the electrical connection component 820 and the metal plate 14.
　｛第２実施形態の変形例｝
　第２実施形態において、ハウジング本体８５１が別体に設けられた第１合体部分８５６と第２合体部分８５７とで構成されるものとして説明したが、このことは必須ではない。例えば図１５に示す第１変形例に係る電気接続部品９２０のように、ハウジング本体９５１が相互にヒンジ９６２で開閉可能に連結された第１開閉部分９６０と第２開閉部分９６１とで構成されていてもよい。 {Modification of Second Embodiment}
In 2nd Embodiment, although the housing main body 851 demonstrated as what is comprised with the 1st unification part 856 and the 2nd unification part 857 which were provided separately, this is not essential. For example, like the electrical connection component 920 according to the first modification shown in FIG. 15, the housing body 951 is configured by a first opening / closing portion 960 and a second opening / closing portion 961 that are connected to each other by a hinge 962 so as to be opened and closed. May be.
　具体的には、第１開閉部分９６０は、金属板１４の周方向に沿った一部分を覆う。第２開閉部分９６１は、金属板１４の周方向に沿った他部分を覆う。第１開閉部分９６０の主要な部分は、凸部８５８以外については第１合体部分８５６と同様の形状に形成される。第２開閉部分９６１の主要な部分は、凹部８５９以外については第２合体部分８５７と同様の形状に形成される。また、第２開閉部分９６１は、第１開閉部分９６０とヒンジ９６２で開閉可能に連結されている。ハウジング本体９５１は、第１開閉部分９６０と第２開閉部分９６１とが閉じた状態で金属板１４の全周を囲繞可能である。 Specifically, the first opening / closing portion 960 covers a part of the metal plate 14 along the circumferential direction. The second opening / closing part 961 covers other parts along the circumferential direction of the metal plate 14. The main part of the first opening / closing part 960 is formed in the same shape as the first combined part 856 except for the convex part 858. The main part of the second opening / closing part 961 is formed in the same shape as the second combined part 857 except for the recess 859. The second opening / closing portion 961 is connected to the first opening / closing portion 960 and a hinge 962 so as to be opened and closed. The housing body 951 can surround the entire circumference of the metal plate 14 with the first opening / closing portion 960 and the second opening / closing portion 961 closed.
　また、電気接続部品９２０には、ヒンジ９６２の反対側に閉状態を維持可能なロック部９６３が設けられている。ロック部９６３はロック片９６４とロック片９６４が挿通可能に且つ挿通後に係止可能なロック凹部９６５とで構成されている。図１５に示す例では、ロック片９６４が第２開閉部分９６１に設けられ、ロック凹部９６５が第１開閉部分９６０に設けられているが、逆の配置であってもよい。 In addition, the electrical connection component 920 is provided with a lock portion 963 capable of maintaining a closed state on the opposite side of the hinge 962. The lock portion 963 includes a lock piece 964 and a lock recess 965 that allows the lock piece 964 to be inserted and can be locked after the insertion. In the example shown in FIG. 15, the lock piece 964 is provided in the second opening / closing part 961 and the lock recess 965 is provided in the first opening / closing part 960, but the arrangement may be reversed.
　このような電気接続部品９２０によると、第１開閉部分９６０と第２開閉部分９６１とが開いた状態で電気接続部品９２０の内部に金属板１４を挿通させることができる。これにより、電気接続部品９２０を電線１２に取付容易となる。また、第１開閉部分９６０と第２開閉部分９６１とが閉じた状態で、金属板１４の全周を囲繞可能であるため、電気接続部品９２０と電線１２とに位置ずれ等が生じにくい。 According to such an electrical connection component 920, the metal plate 14 can be inserted into the electrical connection component 920 with the first opening / closing portion 960 and the second opening / closing portion 961 open. Thereby, it becomes easy to attach the electrical connection component 920 to the electric wire 12. In addition, since the entire periphery of the metal plate 14 can be surrounded with the first opening / closing portion 960 and the second opening / closing portion 961 closed, misalignment or the like hardly occurs between the electrical connection component 920 and the electric wire 12.
　また、第２実施形態において、ワイヤーハーネス８１０が電線１２を１つ備えるものとして説明したが、このことは必須ではない。ワイヤーハーネスは、複数の電線１２を備えるものであってもよい。この場合、複数の電線１２は、薄手方向に並ぶように設けられるとよい。複数の電線１２それぞれに対して別の電気接続部品８２０が接続されていることが考えられる。もっとも、複数の電線１２に対して１つの電気接続部品が一括して接続されている場合も考えられる。このように複数の電線１２に一括して接続可能な電気接続部品の例を図１６に示す。 In the second embodiment, the wire harness 810 has been described as including one electric wire 12, but this is not essential. The wire harness may include a plurality of electric wires 12. In this case, the plurality of electric wires 12 are preferably provided so as to be arranged in the thin direction. It is conceivable that another electrical connection component 820 is connected to each of the plurality of electric wires 12. But the case where one electrical connection component is collectively connected with respect to the some electric wire 12 is also considered. FIG. 16 shows an example of an electrical connection component that can be connected to the plurality of electric wires 12 at once.
　図１６に示す第２変形例に係る電気接続部品１０２０では、２つのバスバ８３０が１つのハウジング１０５０に保持されている。従って、ハウジング本体１０５１は２つの第１収容部８５２を含んだ形状に形成されている。２つのバスバ８３０は、それぞれの当接部８３４が金属板１４との当接方向に並ぶように設けられている。各バスバ８３０に対して、第２実施形態に係る電気接続部品８２０と同様に、コネクタ８７０が接続されている。従って、ハウジング本体１０５１には２つのバスバ８３０にそれぞれ接続されるコネクタ８７０を収める第２収容部８５３が形成されることが考えられる。図１６に示す例では、一方のバスバ８３０に接続されるコネクタ８７０を収める第２収容部８５３の下方に、他方のバスバ８３０に接続されるコネクタ８７０を収める第２収容部８５３が形成されている。もっとも、図１７に示す第３変形例に係る電気接続部品１１２０のように、２つのバスバ８３０に対して１つのコネクタ１１７０が接続されるものであってもよい。この場合、ハウジング本体１１５１には、第２収容部１１５４が１つ形成される。このような電気接続部品１０２０、１１２０によると、１つの部品で、複数の電線１２に接続できる。 In the electrical connection component 1020 according to the second modification shown in FIG. 16, two bus bars 830 are held in one housing 1050. Therefore, the housing main body 1051 is formed in a shape including the two first accommodating portions 852. The two bus bars 830 are provided so that the respective contact portions 834 are aligned in the contact direction with the metal plate 14. A connector 870 is connected to each bus bar 830 in the same manner as the electrical connection component 820 according to the second embodiment. Therefore, it is conceivable that the housing body 1051 is formed with a second housing portion 853 for housing the connectors 870 connected to the two bus bars 830, respectively. In the example shown in FIG. 16, a second housing portion 853 for housing the connector 870 connected to the other bus bar 830 is formed below the second housing portion 853 for housing the connector 870 connected to one bus bar 830. . However, one connector 1170 may be connected to the two bus bars 830 as in the electrical connection component 1120 according to the third modification shown in FIG. In this case, one second housing portion 1154 is formed in the housing main body 1151. According to such electrical connection components 1020 and 1120, a single component can be connected to the plurality of electric wires 12.
　また、第２実施形態において、複数の端子部８３３が金属板１４の厚み方向に並ぶものとして説明したが、このことは必須ではない。例えば、図１８に示す第４変形例に係る電気接続部品１２２０のように、複数の端子部１２３３が金属板１４の延在方向に沿って並ぶものであってもよい。 In the second embodiment, it has been described that the plurality of terminal portions 833 are arranged in the thickness direction of the metal plate 14, but this is not essential. For example, a plurality of terminal portions 1233 may be arranged along the extending direction of the metal plate 14 as in an electrical connection component 1220 according to a fourth modification shown in FIG.
　また、第２実施形態において、１つのバスバ８３０に１つのコネクタ８７０が接続されるものとして説明したが、このことは必須ではない。１つのバスバ８３０に複数のコネクタ８７０が接続されるものであってもよい。また、２つのバスバ８３０にそれぞれコネクタ８７０が接続される場合、複数のコネクタ８７０が金属板１４の厚み方向に並ぶものとして説明したが、このことは必須ではない。複数のコネクタ８７０が金属板１４の延在方向に沿って並ぶものであってもよい。 In the second embodiment, it has been described that one connector 870 is connected to one bus bar 830, but this is not essential. A plurality of connectors 870 may be connected to one bus bar 830. Further, when the connectors 870 are connected to the two bus bars 830, respectively, it has been described that the plurality of connectors 870 are arranged in the thickness direction of the metal plate 14, but this is not essential. A plurality of connectors 870 may be arranged along the extending direction of the metal plate 14.
　例えば、電気接続部品１２２０においてコネクタ８７０を挿入保持可能な４つのキャビティ１２５４ａ、１２５４ｂ、１２５４ｃ、１２５４ｄが設けられているが、そのうち上側（金属板１４の厚み方向一方側）２つのキャビティ１２５４ａ、１２５４ｂに挿入接続されるコネクタ８７０が上側のバスバ８３０に接続可能であると共に下側（金属板１４の厚み方向他方側）２つのキャビティ１２５４ｃ、１２５４ｄに挿入接続されるコネクタ８７０が下側のバスバ８３０に接続可能であってもよい。また、左側（金属板１４の延在方向一方側）２つのキャビティ１２５４ａ、１２５４ｃに挿入接続されるコネクタ８７０が上側のバスバ８３０に接続可能であると共に右側（金属板１４の延在方向他方側）２つのキャビティ１２５４ｂ、１２５４ｄに挿入接続されるコネクタ８７０が下側のバスバ８３０に接続可能であってもよい。 For example, four cavities 1254a, 1254b, 1254c, and 1254d in which the connector 870 can be inserted and held in the electrical connection component 1220 are provided. The connector 870 to be inserted and connected can be connected to the upper bus bar 830, and the connector 870 to be inserted and connected to the two cavities 1254c and 1254d on the lower side (the other side in the thickness direction of the metal plate 14) is connected to the lower bus bar 830. It may be possible. Further, a connector 870 inserted and connected to the two cavities 1254a and 1254c on the left side (one side in the extending direction of the metal plate 14) can be connected to the upper bus bar 830, and the right side (the other side in the extending direction of the metal plate 14). The connector 870 inserted and connected to the two cavities 1254b and 1254d may be connectable to the lower bus bar 830.
　また、これまでコネクタ８７０が電線１２に対して側方に位置するものとして説明してきたが、このことは必須ではない。例えば、コネクタ８７０は、電線１２に対して上方又は下方に位置するものであってもよい。 In the above description, the connector 870 has been described as being lateral to the electric wire 12, but this is not essential. For example, the connector 870 may be located above or below the electric wire 12.
　｛その他の変形例｝
　上記各実施形態において、電気接続部品における金属板側接続部が金属板１４と面接触するものとして説明してきたが、このことは必須の構成ではない。例えば、図１９に示す電気接続部品１３２０のようにバスバ１３３０における当接部１３３４が、金属板１４と点接触する場合も考えられる。 {Other variations}
In each said embodiment, although the metal plate side connection part in an electrical connection component has demonstrated as what is surface-contacted with the metal plate 14, this is not an essential structure. For example, a case where the contact portion 1334 of the bus bar 1330 makes point contact with the metal plate 14 as in the electrical connection component 1320 shown in FIG.
　図１９に示す例では、当接部１３３４は、連結部１３３６から片持ち梁状に延びる梁部１３３４ａと、梁部１３３４ａから金属板１４側へ突出するように設けられた突部１３３４ｂとを有している。この際、バスバ１３３０においてかかる当接部１３３４が、金属板１４を挟持可能に一対設けられている。なお、金属板側接続部が金属板１４と点接触する場合、図１９に示すように、ハウジング１３５０における第１収容部１３５２が金属板１４の全周を覆うことが好ましい。 In the example shown in FIG. 19, the contact portion 1334 has a beam portion 1334a extending in a cantilever shape from the connecting portion 1336, and a protrusion 1334b provided so as to protrude from the beam portion 1334a to the metal plate 14 side. is doing.
