Description

本発明は、インバータ装置の機器内配線等に用いられる車両用の機器用配線集合に関する。 The present invention relates to a device wiring set for a vehicle used for wiring in a device of an inverter device.

車両用の大電流用のワイヤハーネスは、車両に搭載されたインバータ装置等の機器に接続される。ワイヤハーネスのコネクタがメス端子である場合には、オス端子（バスバ端子）が機器側（例えば、機器内部）に配置される。オス端子と機器内の接続端子との接続には、機器用配線部材が用いられる。 A large-current wire harness for a vehicle is connected to a device such as an inverter device mounted on the vehicle. When the connector of the wire harness is a female terminal, the male terminal (bus bar terminal) is arranged on the device side (for example, inside the device). A device wiring member is used to connect the male terminal to the connection terminal in the device.

機器用配線部材は、素線を撚り合わせた撚線導体と、撚線導体の両端に設けられる２つ接続部と、を備えて構成されている（例えば、特許文献１参照）。 The device wiring member is configured to include a stranded wire conductor in which strands are twisted together, and two connecting portions provided at both ends of the stranded wire conductor (see, for example, Patent Document 1).

ところで、近年、車両に搭載されるインバータ装置等の機器では、小型化が進んでいる。このような機器の小型化に伴い、当該機器に用いられる機器用配線部材は、特許文献１の図７に示されるような長尺のものではなく、短尺のものが要求されている。さらに、機器の小型化に伴い、機器内で配線する際（機器内の配線作業）には、機器用配線部材を、例えば直角（９０度）に屈曲させることも要求されている。 By the way, in recent years, devices such as an inverter device mounted on a vehicle have been downsized. With such miniaturization of equipment, a wiring member for equipment used in the equipment is required to have a short length rather than a long length as shown in FIG. 7 of Patent Document 1. Further, with the downsizing of equipment, it is required to bend the equipment wiring member, for example, at a right angle (90 degrees) when wiring in the equipment (wiring work in the equipment).

しかしながら、機器用配線部材は、大電流で使用されるため、撚線導体の導体断面積を所定の大きさとする必要があり、所定の剛性を有している。そのため、大電流で使用される機器用配線部材は、屈曲し難いという課題がある。 However, since the device wiring member is used with a large current, it is necessary to set the conductor cross-sectional area of the stranded wire conductor to a predetermined size, and has a predetermined rigidity. Therefore, there is a problem that a wiring member for equipment used with a large current is difficult to bend.

さらに、上述のように、近年では、機器用配線部材も短尺のものが要求されており、短尺であるが故に屈曲し難いという課題は顕著であった。この屈曲のし難さという課題は、配線作業における微調整がし難い課題にも繋がっている。 Further, as described above, in recent years, a short wiring member for equipment has been required, and the problem that it is difficult to bend because of the short length has been remarkable. This problem of difficulty in bending also leads to a problem that it is difficult to finely adjust the wiring work.

本発明は、上記課題に鑑みなされたもので、たとえ短尺化した場合であっても、屈曲のし難さを低減することができる車両用の機器用配線集合を提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a device wiring set for a vehicle, which can reduce the difficulty of bending even when the length is shortened.

本発明は、上記課題を解決することを目的として、素線を複数本撚り合わせた子撚り線をさらに複数本撚り合わせた複合撚線導体である撚線導体と前記撚線導体の両端に設けられた２つの接続部とを有する機器用配線部材を複数備えた車両用の機器用配線集合体において、複数の前記機器用配線部材を所定間隔で保持する保持部材を備え、前記２つの接続部は、前記撚線導体の一方の端部に設けられ、ワイヤハーネスのメス端子が嵌合され接続されるオス端子と、前記撚線導体の他方の端部に設けられ、機器の接続端子と接続される圧着端子とからなり、前記撚線導体の中央部は、配線の際に屈曲させる部分である配線屈曲部を含み、前記配線屈曲部における前記複数本の子撚り線が撚り合わされた状態が維持されつつ前記配線屈曲部における前記子撚り線同士の撚りが両端側よりほぐれており、前記保持部材は、前記撚線導体の中央部を保持しておらず、前記撚線導体の前記圧着端子側に近い端側の１箇所を保持している、車両用の機器用配線集合体を提供する。 The present invention, for the purpose of solving the above problems, provides a twisted wire conductor which is a composite twisted wire conductor in which a plurality of twisted wires obtained by twisting a plurality of strands are further twisted and the both ends of the twisted wire conductor. in equipment wiring assembly for a vehicle having a plurality of wiring members equipment having two connecting portions which are provided with a holding member for holding the wire member for a plurality of the devices at predetermined intervals, said two connection The portion is provided at one end of the stranded wire conductor, a male terminal to which a female terminal of a wire harness is fitted and connected, and a other end of the stranded wire conductor, which is provided as a connection terminal of a device. The crimp terminal to be connected, the central portion of the twisted wire conductor includes a wiring bent portion that is a portion to be bent during wiring, and a state in which the plurality of child twisted wires in the wiring bent portion are twisted together. The twisting of the child twisted wires in the bent portion of the wiring is unraveled from both end sides while maintaining, and the holding member does not hold the central portion of the twisted wire conductor, and the crimping of the twisted wire conductor is performed. ( EN ) Provided is a device wiring assembly for a vehicle, which holds one end side near a terminal side .

本発明によれば、たとえ短尺化した場合であっても、屈曲のし難さを低減することができる車両用の機器用配線集合体を提供できる。 According to the present invention, it is possible to provide a device wiring assembly for a vehicle, which can reduce the difficulty of bending even when the length is shortened.

［実施の形態］
以下、本発明の実施の形態を添付図面にしたがって説明する。 [Embodiment]
Embodiments of the present invention will be described below with reference to the accompanying drawings.

（車両用の機器用配線部材の説明）
図１は、本実施の形態に係る車両用の機器用配線部材（以下、単に機器用配線部材という）の斜視図である。 (Explanation of wiring members for equipment for vehicles)
FIG. 1 is a perspective view of a device wiring member for a vehicle (hereinafter, simply referred to as a device wiring member) according to the present embodiment.

図１に示すように、機器用配線部材１は、複数本の素線を撚り合わせた撚線導体２と、撚線導体２の両端に設けられる２つ接続部３，４と、を備えている。 As shown in FIG. 1, the device wiring member 1 includes a stranded wire conductor 2 in which a plurality of element wires are twisted together, and two connecting portions 3 and 4 provided at both ends of the stranded wire conductor 2. There is.

機器用配線部材１は、車両に搭載される機器の機器内配線等に用いられ、例えば最大で２００〜５００Ａの大電流が導通されるものである。本実施の形態では、一例として、電気自動車やハイブリッド車において走行用の電動モータにモータ電流を供給するインバータ装置の機器内配線に機器用配線部材１を用いる場合について説明する。 The device wiring member 1 is used for, for example, in-device wiring of a device mounted on a vehicle, and conducts a large current of, for example, 200 to 500 A at the maximum. In the present embodiment, as an example, a case where the device wiring member 1 is used as the device internal wiring of an inverter device that supplies a motor current to a running electric motor in an electric vehicle or a hybrid vehicle will be described.

撚線導体２は、例えば、外径０．３２ｍｍの素線（銅やアルミニウム等の電気良導体）を１７本撚り合わせて子撚り線とし、この子撚り線をさらに１９本撚り合わせた複合撚線導体であり、撚線導体２全体の外径は例えば７．５ｍｍである。また、撚線導体２の撚りピッチ（任意の素線が周方向の同じ位置となる長手方向に沿った間隔）は例えば２３ｍｍ、導体断面積は例えば５０ｍｍ^２である。撚線導体２の長さは、機器用配線部材１を適用する機器における配線長に応じて設定されるが、例えば、８０ｍｍと短尺（例えば５０ｍｍ〜１５０ｍｍ）である。 The stranded wire conductor 2 is, for example, a composite stranded wire in which 17 strands (electrically good conductors such as copper and aluminum) having an outer diameter of 0.32 mm are twisted together to form a child stranded wire, and further 19 stranded wires are stranded. It is a conductor, and the outer diameter of the whole stranded wire conductor 2 is 7.5 mm, for example. The twist pitch of the stranded wire conductor 2 (the interval along the longitudinal direction where arbitrary strands are at the same position in the circumferential direction) is, for example, 23 mm, and the conductor cross-sectional area is, for example, 50 mm ² . The length of the stranded wire conductor 2 is set according to the wiring length in the device to which the device wiring member 1 is applied, and is 80 mm and a short length (for example, 50 mm to 150 mm).

なお、機器用配線部材１の導体として、単線を用いることも考えられるが、断面積の大きい単線を用いた場合には、機器用配線部材１を屈曲させることが困難となり、配線作業時の微調整を行うことも困難になる。つまり、機器用配線部材１の導体として撚線導体２を用いることで、単線を用いた場合と比較して屈曲させやすくなり、配線作業時の微調整も容易になる。また、予め素線を撚り合わせた撚線導体２（複合撚線導体）を用いることで、多数の素線がばらばらにならないように一体に保持することが可能であり、後述する超音波接合等の作業が容易になる。 Although it is conceivable to use a single wire as the conductor of the device wiring member 1, it is difficult to bend the device wiring member 1 when a single wire having a large cross-sectional area is used, and a fine wire is required during wiring work. It is also difficult to make adjustments. That is, by using the stranded wire conductor 2 as the conductor of the device wiring member 1, it is easier to bend the wire conductor 2 as compared with the case where a single wire is used, and fine adjustment during wiring work is also facilitated. Further, by using the stranded wire conductor 2 (composite stranded wire conductor) in which the wires are twisted in advance, it is possible to hold a large number of the wires together so as not to come apart from each other. Work becomes easier.

撚線導体２の外周には、絶縁体からなる絶縁チューブ５が設けられている。本実施の形態では、撚線導体２に大電流が導通され高温となるため、絶縁チューブ５としては、耐熱性の優れたものを用いる必要がある。具体的には、絶縁チューブ５としては、１５０℃〜２００℃程度の耐熱性を有するものを用いることが望ましく、例えば、シリコンゴムからなるものを用いることができる。 An insulating tube 5 made of an insulator is provided on the outer circumference of the stranded conductor 2. In the present embodiment, since a large current is conducted to the stranded conductor 2 and the temperature becomes high, it is necessary to use the insulating tube 5 having excellent heat resistance. Specifically, as the insulating tube 5, it is desirable to use one having heat resistance of about 150° C. to 200° C., for example, one made of silicone rubber can be used.

絶縁チューブ５は、絶縁チューブ５内で撚線導体２が滑り、撚線導体２がある程度自由に動くことができるように構成されている。詳細は後述するが、本実施の形態では、撚線導体２の一部において子撚り線同士の撚りをほぐすため、ほぐした位置（配線屈曲部）において子撚り線間に隙間ができ撚線導体２が径方向外方に膨らんだ状態となる。絶縁チューブ５は、この撚線導体２の径方向外方への膨らみを考慮して、あらかじめ膨らんだ後の外形（外径）に合わせてチューブ径を選定する。 The insulating tube 5 is configured so that the stranded wire conductor 2 can slide in the insulating tube 5 and the stranded wire conductor 2 can move to some extent. Although the details will be described later, in the present embodiment, since twisting between the child twisted wires is unwound in a part of the twisted wire conductor 2, a gap is formed between the child twisted wires at the unwound position (wiring bent portion). 2 is in a state of bulging outward in the radial direction. The tube diameter of the insulating tube 5 is selected in consideration of the outward bulging of the stranded wire conductor 2 in accordance with the outer shape (outer diameter) of the bulged wire in advance.

具体的には、絶縁チューブ５としてナイロンからなるものを用いる場合、絶縁チューブ５の厚さは、２ｍｍ以下とすることが望ましい。また、絶縁チューブ５の機械的強度を確保し絶縁性能を維持するという観点からは、絶縁チューブ５の厚さは、０．５ｍｍ以上とすることが望ましい。 Specifically, when the insulating tube 5 made of nylon is used, the thickness of the insulating tube 5 is preferably 2 mm or less. From the viewpoint of ensuring the mechanical strength of the insulating tube 5 and maintaining the insulating performance, the thickness of the insulating tube 5 is preferably 0.5 mm or more.

撚線導体２の両端は絶縁チューブ５から露出されており、この撚線導体２の両端に接続部３，４がそれぞれ設けられている。 Both ends of the stranded wire conductor 2 are exposed from the insulating tube 5, and the connecting portions 3 and 4 are provided at both ends of the stranded wire conductor 2.

本実施の形態では、２つの接続部３，４は、図示しないワイヤハーネスのメス端子が嵌合され接続されるオス端子３ａと、機器の接続端子と接続される圧着端子４ａと、からなる。 In the present embodiment, the two connecting portions 3 and 4 include a male terminal 3a into which a female terminal of a wire harness (not shown) is fitted and connected, and a crimp terminal 4a connected to a connecting terminal of a device.

オス端子３ａは、電気良導体からなる板状の部材、すなわちバスバ端子からなり、その先端側（撚線導体２の延出側と反対側）には、ワイヤハーネスのメス端子への挿入を容易とするために面取り加工が施されている。 The male terminal 3a is a plate-shaped member made of a good electrical conductor, that is, a bus bar terminal, and its tip side (the side opposite to the extending side of the stranded wire conductor 2) facilitates insertion into the female terminal of the wire harness. Chamfering is performed to do this.

なお、図示していないが、ワイヤハーネスのメス端子は、例えば、オス端子３ａの先端部を挿入する挿入穴が形成された筒状部を有し、筒状部内に設けられた弾性部材等の押圧部材により、筒状部内に挿入されたオス端子３ａを押圧してオス端子３ａとメス端子とが電気的に接続されるように構成されている。ワイヤハーネスは配線作業時に作業者が把持するものであるため、作業者がメス端子に直接触れることができないようにタッチプロテクト構造となっている。ワイヤハーネス側をメス端子、機器側（機器用配線部材１側）をオス端子３ａとすることで、ワイヤハーネス側のタッチプロテクト構造を容易に実現することが可能になる。 Although not shown, the female terminal of the wire harness has, for example, a tubular portion having an insertion hole into which the tip portion of the male terminal 3a is inserted, and an elastic member or the like provided in the tubular portion. The pressing member is configured to press the male terminal 3a inserted in the tubular portion to electrically connect the male terminal 3a and the female terminal. Since the wire harness is to be gripped by a worker during wiring work, it has a touch protection structure so that the worker cannot directly touch the female terminal. By using the female terminal on the wire harness side and the male terminal 3a on the device side (device wiring member 1 side), it is possible to easily realize the touch protect structure on the wire harness side.

本実施の形態では、オス端子３ａと撚線導体２とは、超音波接合（超音波溶着）により接続されている。超音波接合を行う際には、撚線導体２の素線（子撚り線）がばらばらにならないように、全体が撚られた状態のまま接合を行う。 In the present embodiment, the male terminal 3a and the stranded wire conductor 2 are connected by ultrasonic bonding (ultrasonic welding). When ultrasonic bonding is performed, bonding is performed with the whole twisted state so that the strands (child twisted wires) of the stranded conductor 2 are not disjointed.

圧着端子４ａは、ボルト穴４１ａが形成された板状の接続部４１と、接続部４１の基端側（撚線導体２の延出側）に形成され撚線導体２を圧着固定（かしめ固定）するための導体固定部４２と、を一体に備えている。導体固定部４２は筒状に形成されており、その中空部に撚線導体２の端部を挿入した後に導体固定部４２を変形させる（押し潰す）ことで、撚線導体２を導体固定部４２に圧着固定するように構成されている。撚線導体２の圧着固定を行う際には、撚線導体２の素線（子撚り線）がばらばらにならないように、全体が撚られた状態のまま圧着固定を行う。 The crimp terminal 4a is formed on the base end side (extension side of the stranded wire conductor 2) of the connection portion 41 and the plate-shaped connecting portion 41 in which the bolt hole 41a is formed, and is crimped and fixed (caulked and fixed). And a conductor fixing portion 42 for integrally forming. The conductor fixing portion 42 is formed in a tubular shape, and the conductor fixing portion 42 is deformed (crushed) after the end portion of the stranded wire conductor 2 is inserted into the hollow portion of the conductor fixing portion 42. It is configured to be crimped and fixed to 42. When crimping and fixing the stranded wire conductor 2, the stranded wire conductor 2 is crimped and fixed in a completely twisted state so that the strands (child twisted wires) of the stranded wire conductor 2 are not disjointed.

さて、本実施の形態に係る機器用配線部材１では、撚線導体２の中央部２１は、配線の際に屈曲させる部分であって子撚り線同士の撚りが両端側よりほぐれている配線屈曲部（中央部２１の一部）を含んでおり、この配線屈曲部にて、所定の角度に屈曲（湾曲）されている。 In the device wiring member 1 according to the present embodiment, the center portion 21 of the stranded wire conductor 2 is a portion that is bent during wiring, and the twisting of the child twisted wires is loosened from both ends. The wiring bent portion is bent (curved) at a predetermined angle.

なお、ここでいう中央部２１とは、撚線導体２の両端側の部分（撚りピッチが細かい部分）、すなわち接続部３，４の近傍の部分を除いた部分であり、撚線導体２の両端部を除いた中間部分をいう。また、図１では、一例として、撚線導体２を直角（９０度）に屈曲させた場合を示しているが、撚線導体２を屈曲させる角度は、機器の配線レイアウト等に応じて適宜変更可能である。 The central portion 21 mentioned here is a portion excluding the portions on both end sides of the stranded wire conductor 2 (portions having a fine twist pitch), that is, the portions in the vicinity of the connecting portions 3 and 4, and the stranded wire conductor 2 The middle part excluding both ends. Further, in FIG. 1, as an example, the case where the stranded wire conductor 2 is bent at a right angle (90 degrees) is shown, but the angle at which the stranded wire conductor 2 is bent is appropriately changed according to the wiring layout of the device. It is possible.

撚線導体２において、子撚り線同士の撚りをほぐすと、曲がり癖（巻き癖）の影響により、当該子撚り線同士の撚りをほぐした位置において子撚り線間に隙間ができ、撚線導体２が径方向外方に膨らんだ状態となる。この状態で撚線導体２を屈曲させることで、形成された隙間や外方に子撚り線が移動して容易に屈曲させることが可能になる。 In the twisted wire conductor 2, when the twists of the child twisted wires are unraveled, a gap is created between the child twisted wires at the position where the twists of the child twisted wires are unwound due to the influence of the bending tendency (winding tendency). 2 is in a state of bulging outward in the radial direction. By bending the stranded conductor 2 in this state, the twisted strands can be moved to the formed gap or outward and easily bent.

また、本実施の形態では、ワイヤハーネスのメス端子が嵌合され接続されるオス端子３ａを撚線導体２に接続しているが、ワイヤハーネスのメス端子に嵌合する際に、撚線導体２における子撚り線同士の撚りがほぐれている中央部２１（配線屈曲部）が調整部分となりオス端子３ａの動きを許容することが可能となり、嵌合時にオス端子３ａが少し動くことで、ワイヤハーネスのメス端子との接続性を向上させることも可能になる。 Further, in the present embodiment, the male terminal 3a to which the female terminal of the wire harness is fitted and connected is connected to the stranded wire conductor 2. However, when the male terminal 3a is fitted to the female terminal of the wire harness, the stranded wire conductor is used. The central portion 21 (wiring bent portion) in which the twist of the twisted pair of wires in 2 becomes an adjustment portion, and it is possible to allow the movement of the male terminal 3a. It is also possible to improve the connectivity with the female terminal of the harness.

子撚り線同士の撚りをほぐす方法として、例えば、子撚り線同士の撚り方向と反対方向に撚線導体２を回転させる（捩る）方法が挙げられる。この場合、子撚り線同士の撚りのほぐし具合は、撚りをほぐす際の撚線導体２の回転量（捩り角度）により調整することができる。なお、撚線導体２の中央部２１の一部のみで局所的に撚りがほぐされていてもよいし、中央部２１の略全体で緩やかに撚りがほぐされていてもよい。すなわち、中央部２１のうち、少なくとも屈曲される部分にて撚りがほぐされていればよい。 As a method for loosening the twist between the twisted pair wires, for example, there is a method of rotating (twisting) the twisted wire conductor 2 in a direction opposite to the twisting direction between the twisted pair wires. In this case, the degree of untwisting of the twisted strands can be adjusted by the amount of rotation (twisting angle) of the twisted wire conductor 2 when untwisting the twisted wires. The twist may be locally untwisted only in a part of the central portion 21 of the stranded wire conductor 2, or may be gently untwisted in substantially the entire central portion 21. That is, it is sufficient that the twist is untied at least in the bent portion of the central portion 21.

撚線導体２の中央部２１における子撚り線同士の撚りのほぐし具合は、素線や子撚り線の外径や本数、屈曲角度等に応じて適宜設定可能であるが、少なくとも、撚線導体２を屈曲させる前の状態（撚線導体２を直線状とした状態）において、中央部２１（配線屈曲部）の最大外径が、両端側（撚りがほぐされていない部分）の最大外径の１．１倍以上となるようにすることで、屈曲性を向上することができる。なお、ここでいう最大外径とは、撚線導体２の長手方向に垂直な方向、すなわち周方向の各位置から見たときの撚線導体２の最大幅（観察方向と対向配置した平面に投影した像の最大幅）をいう。撚線導体２を９０度に屈曲させた際には、その屈曲部分の最大外径（ここでは、両面Ａ，Ｂの法線方向に対して垂直な方向の長さ）が、両端側の最大外径の１．３倍以上となるように構成するとよい。 The degree of twisting of the twisted strands in the central portion 21 of the twisted conductor 2 can be appropriately set according to the outer diameter and the number of strands or twisted strands, the bending angle, etc. In the state before bending 2 (the stranded wire conductor 2 is in a linear shape), the maximum outer diameter of the central portion 21 (wiring bent portion) is the maximum outer diameter of both ends (the portion where the twist is not unraveled). By setting the ratio to be 1.1 times or more, the flexibility can be improved. The maximum outer diameter referred to here is the maximum width of the twisted wire conductor 2 when viewed from each position in the direction perpendicular to the longitudinal direction of the twisted wire conductor 2, that is, in the circumferential direction (in the plane arranged facing the observation direction). The maximum width of the projected image). When the stranded wire conductor 2 is bent at 90 degrees, the maximum outer diameter of the bent portion (here, the length in the direction perpendicular to the normal direction of both surfaces A and B) is the maximum at both ends. It is preferable that the outer diameter is 1.3 times or more.

なお、撚線導体２の子撚り線同士の撚りをほぐしすぎると、当該子撚り線同士の撚りをほぐした位置（配線屈曲部）での撚線導体２の幅（最大外径）が大きくなりすぎ、複数の機器用配線部材１を整列配置して機器用配線集合体（後述する）を構成した際に、隣り合う機器用配線部材１同士、あるいは機器のケース等の周囲の部材と干渉してしまうおそれが生じる。よって、機器へ適用した際に、隣り合う機器用配線部材１や周囲の部材と干渉しない程度の幅（最大外径）となるように、子撚り線同士の撚りのほぐし具合を調整するとよい。周囲の部材との干渉を抑制するという観点から、撚線導体２の全体において、撚線導体２の最大外径がオス端子３ａの幅（厚さ方向および撚線導体２の延出方向（メス端子との嵌合方向）に対して垂直な方向の長さ）よりも小さいことが望ましい。 If the twists of the twisted pair conductors 2 of the twisted conductor 2 are loosened too much, the width (maximum outer diameter) of the twisted conductor 2 at the position where the twists of the twisted pair conductors are loosened (the wire bending portion) becomes large. When a plurality of device wiring members 1 are aligned and arranged to form a device wiring assembly (described later), the device wiring members 1 interfere with each other or adjacent members such as a case of the device. May occur. Therefore, when applied to a device, it is advisable to adjust the degree of untwisting of the twisted strands so that the width (maximum outer diameter) does not interfere with the adjacent device wiring member 1 and surrounding members. From the viewpoint of suppressing interference with surrounding members, in the entire stranded wire conductor 2, the maximum outer diameter of the stranded wire conductor 2 is the width of the male terminal 3a (thickness direction and extension direction of the stranded wire conductor 2 (female). It is desirable that it is smaller than the length (direction perpendicular to the fitting direction with the terminal).

本実施の形態では、非屈曲状態において、オス端子３ａの撚線導体２を接合した面Ａと、圧着端子４ａの接続部４１における撚線導体２を接続した側の面Ｂとを同一平面上に配置した後、両面Ａ，Ｂが近接する方向に撚線導体２を９０度屈曲させて機器用配線部材１を構成している。９０度に屈曲させたときのオス端子３ａの先端から圧着端子４ａの面Ｂと反対側の面までの距離Ｈは例えば７０ｍｍであり、圧着端子４ａの先端からオス端子３ａの面Ａと反対側の面までの距離Ｗは例えば６０ｍｍである。なお、機器用配線部材１は、機器に設けられ配線に使用された状態で屈曲されていればよく、未配線状態では屈曲されていなくてもよい。また、両端子３ａ，４ａの面Ａ，Ｂの向きは適用する機器の接続端子の配置等に応じて適宜決定すればよく、両端子３ａ，４ａの面Ａ，Ｂの向きは図示の方向に限定されない。 In the present embodiment, in the non-bent state, the surface A on which the stranded wire conductor 2 of the male terminal 3a is joined and the surface B on the side where the stranded wire conductor 2 is connected in the connection portion 41 of the crimp terminal 4a are on the same plane. After that, the stranded wire conductor 2 is bent 90 degrees in the direction in which the two surfaces A and B are close to each other to form the device wiring member 1. A distance H from the tip of the male terminal 3a to the surface opposite to the surface B of the crimp terminal 4a when bent at 90 degrees is, for example, 70 mm, and the distance H from the tip of the crimp terminal 4a to the surface A of the male terminal 3a. The distance W to the surface is, for example, 60 mm. The device wiring member 1 may be bent in a state provided in the device and used for wiring, and may not be bent in an unwired state. Further, the directions of the surfaces A and B of both terminals 3a and 4a may be appropriately determined in accordance with the arrangement of the connection terminals of the applicable device, and the directions of the surfaces A and B of both terminals 3a and 4a are in the directions shown in the drawing.

ところで、車両用の機器用配線部材１では、車両の振動による影響を大きく受けるため、繰り返し振動を受けた際の信頼性が重要になる。機器用配線部材１のオス端子３ａにワイヤハーネスのメス端子を接続すると、ワイヤハーネスから機器用配線部材１に振動が伝わり、オス端子３ａと撚線導体２の接続部が振動し、オス端子３ａの基端部の角部Ｃが撚線導体２と干渉して撚線導体２に損傷や断線等の不具合が生じるおそれがある。 By the way, since the device wiring member 1 for a vehicle is greatly affected by the vibration of the vehicle, reliability when repeatedly subjected to the vibration is important. When the female terminal of the wire harness is connected to the male terminal 3a of the device wiring member 1, vibration is transmitted from the wire harness to the device wiring member 1 and the connecting portion between the male terminal 3a and the stranded wire conductor 2 vibrates and the male terminal 3a. There is a possibility that the corner portion C of the base end of will interfere with the stranded wire conductor 2 and cause problems such as damage or disconnection of the stranded wire conductor 2.

そこで、本実施の形態では、図２（ａ）に示すように、オス端子３ａとオーバーラップさせた撚線導体２のうち、一部のみを超音波接合により接続している。図２（ａ）における符号２２は、超音波接合がなされた部分（以下、超音波接合部という）を表している。ここでは、オス端子３ａの基端部（撚線導体２の延出側の端部）から所定距離先端側に離れた位置に、超音波接合部２２を形成しており、角部Ｃでは超音波接合を行っていない。 Therefore, in the present embodiment, as shown in FIG. 2A, only a part of the stranded wire conductor 2 overlapping the male terminal 3a is connected by ultrasonic bonding. Reference numeral 22 in FIG. 2A represents a portion where ultrasonic bonding is performed (hereinafter referred to as an ultrasonic bonding portion). Here, the ultrasonic bonding portion 22 is formed at a position distant from the base end portion (the end portion on the extension side of the stranded wire conductor 2) of the male terminal 3a to the front end side by a predetermined distance, and the corner portion C has an ultrasonic bonding portion 22. Sonic bonding is not done.

オス端子３ａとオーバーラップさせた撚線導体２のうち、一部のみ（オス端子３ａの基端部から所定距離先端側に離れた位置）に超音波接合部２２を形成しておくことで、図２（ｂ）に示すように、面Ａの法線方向（上述の面Ａ，Ｂが近接する方向）に撚線導体２を屈曲させると、超音波接合部２２よりも基端側の撚線導体２が、オス端子３ａの基端部における角部Ｃから離間し、これにより、角部Ｃと撚線導体２との干渉を抑制し、振動の影響により撚線導体２に断線等の不具合が発生することを抑制できる。 By forming the ultrasonic bonding portion 22 only on a part (a position apart from the base end portion of the male terminal 3a to the tip side by a predetermined distance) of the stranded wire conductor 2 that is overlapped with the male terminal 3a, As shown in FIG. 2B, when the stranded wire conductor 2 is bent in the normal direction of the surface A (the direction in which the above-mentioned surfaces A and B are close to each other), the twisting on the base end side with respect to the ultrasonic bonding portion 22 is performed. The wire conductor 2 is separated from the corner portion C at the base end portion of the male terminal 3a, thereby suppressing the interference between the corner portion C and the twisted wire conductor 2, and the twisted wire conductor 2 may be disconnected due to the influence of vibration. It is possible to suppress the occurrence of defects.

なお、これに限らず、図３に示すように、オス端子３ａの撚線導体２の延出側の端部（角部Ｃの位置）に、面取り加工（丸め加工）を施すことでも、角部Ｃと撚線導体２との干渉を抑制することが可能である。この場合、オス端子３ａとオーバーラップさせた撚線導体２の全体を超音波接合部２２とし、オス端子３ａと撚線導体２の接続強度をより高めることが可能である。また、この場合において、さらに、オス端子３ａとオーバーラップさせた撚線導体２のうち、一部のみ（オス端子３ａの基端部から所定距離先端側に離れた位置）に超音波接合部２２を形成することで、角部Ｃと撚線導体２との干渉をより抑制し、振動の影響による撚線導体２の断線等の不具合をより抑制することも可能である。 Not limited to this, as shown in FIG. 3, it is also possible to chamfer (round) the end (position of the corner C) on the extension side of the stranded conductor 2 of the male terminal 3a to form a corner. It is possible to suppress the interference between the portion C and the stranded conductor 2. In this case, the entire twisted wire conductor 2 overlapping the male terminal 3a is used as the ultrasonic bonding portion 22, and the connection strength between the male terminal 3a and the twisted wire conductor 2 can be further increased. Further, in this case, the ultrasonic bonding portion 22 is further provided only on a part (a position apart from the base end portion of the male terminal 3a toward the tip end side) of the stranded wire conductor 2 overlapping the male terminal 3a. It is also possible to further suppress the interference between the corner portion C and the stranded wire conductor 2 by forming the above, and to further suppress problems such as disconnection of the stranded wire conductor 2 due to the influence of vibration.

（機器用配線部材１の製造方法の説明）
次に、機器用配線部材１の製造方法について説明する。 (Description of manufacturing method of wiring member 1 for equipment)
Next, a method for manufacturing the device wiring member 1 will be described.

機器用配線部材１を製造する際には、まず、図４（ａ）に示すように、撚線導体２の一端を超音波接合によりオス端子３ａに接続する。このとき、撚線導体２は屈曲されておらず直線状となっている。また、超音波接合の際には、撚線導体２の素線（子撚り線）がばらばらにならないように、全体が撚られた状態のまま接合を行う。 When manufacturing the device wiring member 1, first, as shown in FIG. 4A, one end of the stranded conductor 2 is connected to the male terminal 3a by ultrasonic bonding. At this time, the stranded conductor 2 is not bent and has a linear shape. In addition, during ultrasonic bonding, bonding is performed in the entire twisted state so that the strands (child strands) of the stranded wire conductor 2 do not come apart.

具体的には、超音波接合装置のアンビルにオス端子３ａを固定し、撚線導体２の側方からガイドの型を当てた状態で、撚線導体２に超音波ホーンを押し当て、超音波ホーンを超音波振動させる。すると、撚線導体２の素線が加振され、撚線導体２とオス端子３ａの酸化被膜や表面の不純物が飛散され、接合面に清浄な活性化した金属分子が現れる。さらに超音波振動を与えると、金属原子間の引力により固相溶接状態が作り出され、撚線導体２とオス端子３ａとが接合される。 Specifically, the male terminal 3a is fixed to the anvil of the ultrasonic bonding apparatus, and the ultrasonic horn is pressed against the twisted wire conductor 2 in a state where the guide mold is applied from the side of the twisted wire conductor 2. The horn is ultrasonically vibrated. Then, the strands of the stranded conductor 2 are vibrated, the oxide film of the stranded conductor 2 and the male terminal 3a and impurities on the surface are scattered, and clean activated metal molecules appear on the joint surface. When ultrasonic vibration is further applied, a solid state welded state is created by the attractive force between the metal atoms, and the stranded wire conductor 2 and the male terminal 3a are joined together.

このとき、オス端子３ａと同じ幅か、あるいはオス端子３ａの幅よりも小さい幅となるように、超音波接合部２２を形成するとよい。 At this time, the ultrasonic bonding portion 22 may be formed to have the same width as the male terminal 3a or a width smaller than the width of the male terminal 3a.

その後、図４（ｂ）に示すように、撚線導体２の他端を圧着端子４ａの導体固定部４２に挿入し、導体固定部４２を変形させることで、撚線導体２を圧着端子４ａに圧着固定する。 Then, as shown in FIG. 4B, the other end of the stranded wire conductor 2 is inserted into the conductor fixing portion 42 of the crimp terminal 4a, and the conductor fixing portion 42 is deformed, so that the stranded wire conductor 2 is crimped to the crimp terminal 4a. Crimped and fixed to.

つまり、本実施の形態では、オス端子３ａと撚線導体２とを超音波接合により接続した後に、圧着端子４ａと撚線導体２とを圧着により接続している。これにより、末端を揃えた状態で圧着により圧着端子４ａを取り付けることができ、また、超音波接合の際の振動が圧着端子４ａと撚線導体２との接続部分に悪影響を及ぼすことを抑制できる。 That is, in the present embodiment, after the male terminal 3a and the stranded wire conductor 2 are connected by ultrasonic bonding, the crimp terminal 4a and the stranded wire conductor 2 are connected by crimping. As a result, the crimp terminal 4a can be attached by crimping with the ends aligned, and it is possible to suppress vibration during ultrasonic bonding from having an adverse effect on the connection between the crimp terminal 4a and the stranded conductor 2. ..

その後、図４（ｃ）に示すように、撚線導体２を、子撚り線同士の撚り方向と反対方向に捩る。すると、撚線導体２の中央部２１において、子撚り線同士の撚りがほぐれた状態になる。このとき、撚線導体２が絶縁チューブ５内で移動（回転）して子撚り線同士の撚りがほぐされるため、絶縁チューブ５自体には捩れは生じない。その後、子撚り線同士の撚りがほぐれた撚線導体２の中央部２１にて撚線導体２を屈曲させると、図１の機器用配線部材１が得られる。なお、図４（ａ）〜（ｃ）では、絶縁チューブ５を一点鎖線にて示している。 Thereafter, as shown in FIG. 4C, the stranded wire conductor 2 is twisted in a direction opposite to the twisting direction of the child twisted wires. Then, in the central portion 21 of the twisted wire conductor 2, the twists of the child twisted wires are loosened. At this time, since the twisted wire conductor 2 moves (rotates) in the insulating tube 5 to untwist the twisted wires, the insulating tube 5 itself is not twisted. After that, when the twisted wire conductor 2 is bent at the central portion 21 of the twisted wire conductor 2 in which the twists of the child twisted wires are loosened, the device wiring member 1 of FIG. 1 is obtained. Note that, in FIGS. 4A to 4C, the insulating tube 5 is shown by a dashed line.

本実施の形態では、撚線導体２の撚りをほぐすために撚線導体２を捩る方法を採用しているため、圧着端子４ａは、撚線導体２を捩る作業を行った後に、両端子３ａ，４ａの面Ａ，Ｂが一致するように（面Ａ，Ｂが機器への取付時の位置関係に応じた位置関係となるように）、取付角度が調整される。ここでは、オス端子３ａの面Ａの法線方向と圧着端子４ａ（接続部４１）の面Ｂの法線方向とが垂直となるように圧着端子４ａを取り付けた後、撚線導体２を９０度捩ることで、両面Ａ，Ｂが同一平面上に位置するようにしたが、圧着端子４ａの取付角度は、所望の捩り角度（子撚り線同士の撚りのほぐれ具合）に応じて適宜調整可能である。つまり、圧着端子４ａの取付時の角度（面Ａ，Ｂの相対的な角度）により、撚線導体２の子撚り線同士の撚りのほぐれ具合を調整することが可能である。 In the present embodiment, since the twisted wire conductor 2 is twisted to loosen the twist of the twisted wire conductor 2, the crimp terminal 4a is used after the twisted wire conductor 2 is twisted. , 4a are adjusted so that the surfaces A and B coincide with each other (so that the surfaces A and B have a positional relationship according to the positional relationship at the time of mounting on the device). Here, after attaching the crimp terminal 4a so that the normal direction of the surface A of the male terminal 3a and the normal direction of the surface B of the crimp terminal 4a (connecting portion 41) are perpendicular to each other, Although both sides A and B are positioned on the same plane by twisting once, the mounting angle of the crimp terminal 4a can be appropriately adjusted according to the desired twist angle (the degree of unraveling of the twist of the twisted pair wires). Is. That is, it is possible to adjust the degree of untwisting of the twisted strands of the twisted conductor 2 by adjusting the angle (the relative angle between the surfaces A and B) when the crimp terminal 4a is attached.

また、撚線導体２を捩る際には、両端子３ａ，４ａを把持して捩るようにしてもよいし、撚線導体２の任意の２箇所を把持して捩るようにしてもよい。両端子３ａ，４ａを把持して捩る場合、両端子３ａ，４ａの近傍では、撚線導体２が撚られた状態で固定（接合あるいは圧着）されているため撚りがほぐれにくく、その中間部分である中央部２１にて全体的に（緩やかに）子撚り線同士の撚りがほぐされることになる。他方、撚線導体２の任意の２箇所の位置を把持して捩る場合、当該２箇所の間の部分で局所的に子撚り線同士の撚りがほぐされることになる。よって、例えば、屈曲時の曲げ半径をより小さくしたい場合には、撚線導体２の任意の２箇所を把持して捩り局所的に子撚り線同士の撚りがほぐされるようにし、中央部２１全体で緩やかに湾曲させ屈曲させてもよい場合には、両端子３ａ，４ａを把持して捩り中央部２１の全体で撚りがほぐされるようにしてもよい。 Further, when twisting the stranded wire conductor 2, both terminals 3a and 4a may be gripped and twisted, or any two positions of the stranded wire conductor 2 may be gripped and twisted. When both terminals 3a, 4a are gripped and twisted, the twisted wire conductor 2 is fixed (joined or crimped) in the twisted state in the vicinity of both terminals 3a, 4a, and the twisting is difficult to unravel, and in the middle part thereof. In some central portion 21, the twists of the twisted strands are loosened as a whole (gradually). On the other hand, when gripping and twisting arbitrary two positions of the twisted wire conductor 2, the twist between the child twisted wires is locally loosened in the portion between the two positions. Therefore, for example, when it is desired to reduce the bending radius at the time of bending, arbitrary two points of the stranded wire conductor 2 are gripped to locally untwist the twisted wires, so that the central portion 21 is entirely untwisted. In the case where it is possible to gently bend and bend it, the terminals 3a and 4a may be grasped so that the twist is unwound in the entire twist center portion 21.

なお、撚線導体２の曲がり癖（巻き癖）の影響により、撚線導体２を捩っても撚りが締まる方向に戻る場合も考えられる。このような場合、例えば、撚線導体２を子撚り線同士の撚り方向と反対方向に大きく捩った後に、両端子３ａ，４ａが所望の位置関係となる位置まで撚り方向と同じ方向に捩って戻すようにしてもよい。また、両端子３ａ，４ａが所望の位置関係となる位置まで撚線導体２を捩った後、撚線導体２に治具等で押圧力を加えて撚線導体２の一部を押し潰すことで、両端子３ａ，４ａを所望の位置関係に維持するようにしてもよい。 In addition, even if the stranded wire conductor 2 is twisted, the twisting may return to the tightening direction due to the bending habit (winding habit) of the stranded wire conductor 2. In such a case, for example, the twisted wire conductor 2 is largely twisted in a direction opposite to the twisting direction of the child twisted wires, and then twisted in the same direction as the twisting direction until the terminals 3a and 4a have a desired positional relationship. It may be returned. Moreover, after twisting the stranded wire conductor 2 to a position where both terminals 3a and 4a have a desired positional relationship, a pressing force is applied to the stranded wire conductor 2 with a jig or the like to crush a part of the stranded wire conductor 2. Therefore, both terminals 3a and 4a may be maintained in a desired positional relationship.

本実施の形態では、両端子３ａ，４ａを接続した後に撚線導体２を捩ることで子撚り線同士の撚りをほぐす場合について説明したが、これに限らず、撚線導体２の一端を超音波接合によりオス端子３ａに接続した後に、撚線導体２を屈曲させ、撚線導体２を屈曲させた後に撚線導体２の他端に圧着端子４ａを接続するようにしてもよい。 In the present embodiment, a case has been described in which the twisted wire conductor 2 is twisted after connecting both terminals 3a and 4a to loosen the twist between the child twisted wires, but the present invention is not limited to this, and one end of the twisted wire conductor 2 is The stranded wire conductor 2 may be bent after connecting to the male terminal 3a by sonic bonding, and the crimp terminal 4a may be connected to the other end of the stranded wire conductor 2 after bending the stranded wire conductor 2.

撚線導体２の一端をオス端子３ａに接続した状態で撚線導体２を屈曲させると、撚線導体２を屈曲させる際に各素線に作用する引張または圧縮の応力の影響で、撚線導体２の子撚り線同士の撚りが自然にほぐれた状態となる。その後、撚線導体２の他端に圧着端子４ａを接続するが、撚線導体２を屈曲させた際に撚線導体２の他端において素線（子撚り線）の端部が揃わなくなるので、撚線導体２の他端部を一部切除して素線（子撚り線）の末端を揃えた後に、撚線導体２の他端に圧着端子４ａを圧着固定するとよい。 When the stranded wire conductor 2 is bent in a state where one end of the stranded wire conductor 2 is connected to the male terminal 3a, the stranded wire conductor 2 is affected by the tensile or compression stress acting on each strand when the stranded wire conductor 2 is bent. The twist between the twisted wires of the conductor 2 is naturally unraveled. After that, the crimp terminal 4a is connected to the other end of the stranded wire conductor 2, but when the stranded wire conductor 2 is bent, the ends of the strands (child twisted wires) are not aligned at the other end of the stranded wire conductor 2. It is advisable to partially crimp the other end of the stranded wire conductor 2 to align the ends of the strands (child twisted wires), and then crimp the crimp terminal 4a to the other end of the stranded wire conductor 2.

この場合、撚線導体２の中央部２１から圧着端子４ａ側にかけて、緩やかに子撚り線同士の撚りがほぐれた状態となる。より詳細には、撚線導体２には曲がり癖（巻き癖）があるため、より曲げ半径が小さい中央部２１（屈曲部分）で子撚り線同士の撚りが最もほぐれた状態となり、圧着端子４ａに近づくほど撚りが締まった（ほぐれていない）状態となる。 In this case, the twist of the twisted pair wires is gradually loosened from the central portion 21 of the stranded wire conductor 2 to the side of the crimp terminal 4a. More specifically, since the twisted wire conductor 2 has a bending tendency (winding tendency), the twist of the child twisted wires is most loosened in the central portion 21 (bent portion) where the bending radius is smaller, and the crimp terminal 4a is formed. The closer it is to, the tighter the twist becomes (not loosened).

このような製造方法を適用することで、撚線導体２の子撚り線同士のほぐれを最小限として、撚線導体２の幅（最大外径）の増加を抑制することが可能になる。また、撚線導体２を屈曲させた状態で圧着端子４ａを設けることで、屈曲された状態で各素線（各子撚り線）が圧着固定されることとなるため、撚線導体２が屈曲された状態で維持されやすくなる。 By applying such a manufacturing method, it is possible to minimize the unraveling of the child twisted wires of the twisted wire conductor 2 and suppress an increase in the width (maximum outer diameter) of the twisted wire conductor 2. Further, by providing the crimp terminal 4a in a state in which the stranded wire conductor 2 is bent, each strand (each twisted wire) is crimped and fixed in a bent state, so that the stranded wire conductor 2 is bent. It will be easier to maintain the condition.

（機器用配線集合体の説明）
次に、機器用配線部材１を用いた機器用配線集合体について説明する。 (Explanation of wiring assembly for equipment)
Next, a device wiring assembly using the device wiring member 1 will be described.

図５に示すように、機器用配線集合体５１は、複数の機器用配線部材１と、複数の車両用の機器用配線部材１を所定間隔で保持する保持部材５２と、を備えている。 As shown in FIG. 5, the device wiring assembly 51 includes a plurality of device wiring members 1 and a holding member 52 that holds the plurality of vehicle device wiring members 1 at predetermined intervals.

ここでは、三相交流電力を伝送することを想定し、３つの機器用配線部材１を用いる場合を説明するが、機器用配線部材１の数はこれに限定されず、２つ、あるいは４つ以上であってもよい。 Here, the case where three wiring members 1 for equipment are used is assumed on the assumption that three-phase AC power is transmitted, but the number of wiring members 1 for equipment is not limited to this, and two or four wiring members 1 are used. It may be more than.

保持部材５２としては、１５０℃〜２００℃程度の耐熱性を有する絶縁性樹脂からなるものを用いるとよい。保持部材５２に好適な絶縁性樹脂としては、例えば、ＰＢＴ、ＰＰＳ、ナイロンが挙げられる。なお、保持部材５２は機器用配線部材１と接触する部分が絶縁性樹脂で構成されていればよく、機器用配線部材１と接触しない部分が金属で構成されていてもよい。 As the holding member 52, a member made of an insulating resin having heat resistance of about 150° C. to 200° C. may be used. Examples of the insulating resin suitable for the holding member 52 include PBT, PPS, and nylon. The holding member 52 only needs to be made of an insulating resin in the portion that comes into contact with the device wiring member 1, and may be made of metal in the portion that does not come into contact with the device wiring member 1.

保持部材５２は、全体として直方体状に形成されると共に、機器用配線部材１を保持するための切欠き５３が３つ形成されており、略櫛歯状に形成されている。この切欠き５３に各機器用配線部材１をそれぞれ収容することで、機器用配線部材１が所定間隔で保持される。 The holding member 52 is formed in a rectangular parallelepiped shape as a whole, and three notches 53 for holding the device wiring member 1 are formed, and are formed in a substantially comb-tooth shape. By housing the device wiring members 1 in the notches 53, the device wiring members 1 are held at predetermined intervals.

なお、ここでは、３つの機器用配線部材１を保持する保持部材５２を形成したが、隣り合う機器用配線部材１の間隔を保持するように構成された保持部材を複数備えるようにしてもよい。つまり、保持部材は、一体構成であってもよいし、複数に分割されていてもよい。 Although the holding member 52 that holds the three device wiring members 1 is formed here, a plurality of holding members configured to hold the space between the adjacent device wiring members 1 may be provided. .. That is, the holding member may have an integral structure or may be divided into a plurality of parts.

本実施の形態に係る機器用配線集合体５１では、保持部材５２は、撚線導体２の中央部２１に設けられておらず、撚線導体２の圧着端子４ａ側に近い端側に設けられている。これにより、各機器用配線部材１を保持部材５２により保持させ機器用配線部材１の配線作業を容易としつつも、保持部材５２よりもオス端子３ａ側の撚線導体２（子撚り線同士の撚りがほぐされた中央部２１）が調整部分となり、オス端子３ａの動きを許容することが可能になり、ワイヤハーネスのメス端子を嵌合させる際の接続性を向上させることが可能になる。 In the device wiring assembly 51 according to the present embodiment, the holding member 52 is not provided in the central portion 21 of the stranded wire conductor 2 but is provided on the end side of the stranded wire conductor 2 close to the crimp terminal 4a side. ing. Thereby, the wiring member 1 for each device is held by the holding member 52 to facilitate the wiring work of the wiring member 1 for devices, and the twisted wire conductor 2 (of the twisted wires The central portion 21) in which the twist is unraveled serves as an adjusting portion, and the movement of the male terminal 3a can be allowed, and the connectivity when fitting the female terminal of the wire harness can be improved.

図５では、３つの切欠き５３を等間隔に形成し、３つの機器用配線部材１を等間隔で保持するように保持部材５２を構成した場合を示しているが、適用する機器の配線レイアウトに応じて、各機器用配線部材１の間隔は異なっていてもよい。この場合、各機器用配線部材１のオス端子３ａには共通のワイヤハーネスが接続されることになるため、オス端子３ａの位置は、ワイヤハーネスのメス端子の位置に応じた固定の位置とされ、圧着端子４ａ側の位置（撚線導体２の圧着端子４ａ側の端の間隔）が適宜調整されることになる。 Although FIG. 5 shows the case where the three notches 53 are formed at equal intervals and the holding member 52 is configured to hold the three device wiring members 1 at equal intervals, the wiring layout of the device to be applied is shown. Accordingly, the intervals of the wiring members 1 for each device may be different. In this case, since a common wire harness is connected to the male terminal 3a of each device wiring member 1, the position of the male terminal 3a is a fixed position corresponding to the position of the female terminal of the wire harness. The position on the crimp terminal 4a side (the distance between the ends of the stranded wire conductor 2 on the crimp terminal 4a side) is appropriately adjusted.

また、図５では、３つの機器用配線部材１の長さ（撚線導体２の長さ）が同じ場合を示しているが、機器用配線部材１の長さ（撚線導体２の長さ）は異なっていてもよい。この場合も、各機器用配線部材１のオス端子３ａには共通のワイヤハーネスが接続されることになるため、オス端子３ａの位置は、ワイヤハーネスのメス端子の位置に応じた固定の位置とされ、圧着端子４ａ側の位置（図示上下方向の位置）や撚線導体２の屈曲角度等が適宜調整されることになる。 Further, although FIG. 5 shows the case where the lengths of the three device wiring members 1 (the lengths of the stranded wire conductors 2) are the same, the length of the device wiring member 1 (the length of the stranded wire conductor 2) is shown. ) May be different. Also in this case, since a common wire harness is connected to the male terminal 3a of each device wiring member 1, the position of the male terminal 3a is a fixed position corresponding to the position of the female terminal of the wire harness. Then, the position on the crimp terminal 4a side (the position in the vertical direction in the drawing), the bending angle of the stranded conductor 2, and the like are adjusted appropriately.

（機器への適用例）
次に、機器用配線部材１（機器用配線集合体５１）を車両のインバータ装置に適用した場合の具体的な配置等について説明する。 (Application example to equipment)
Next, a specific arrangement and the like when the device wiring member 1 (device wiring assembly 51) is applied to an inverter device of a vehicle will be described.

図６に示すように、機器用配線部材１は、例えば、車両のインバータ装置６１の機器内配線として用いられる。 As shown in FIG. 6, the device wiring member 1 is used, for example, as a device internal wiring of an inverter device 61 of a vehicle.

インバータ装置６１は、複数のパワートランジスタ等のスイッチング素子やフライホイールダイオード等を有するインバータ本体６２と、インバータ本体６２を収容するアルミニウム等の導電性金属からなるインバータケース６３と、インバータケース６３に設けられたコネクタ部６４と、を備えて構成されている。 The inverter device 61 is provided in the inverter body 62 having a plurality of switching elements such as power transistors and flywheel diodes, the inverter case 63 made of a conductive metal such as aluminum for housing the inverter body 62, and the inverter case 63. And a connector portion 64.

インバータ本体６２は、直流電力をスイッチング素子のオン／オフ状態の切り替えによって交流電力に変換し、変換した交流電力をコネクタ部６４を介して出力するように構成されている。本実施の形態では、三相交流電力を３つの機器用配線部材１を有する機器用配線集合体５１を介して出力するが、図６では、このうち１つの機器用配線部材１のみを図示している。 The inverter main body 62 is configured to convert DC power into AC power by switching the switching element between ON/OFF states and output the converted AC power via the connector unit 64. In the present embodiment, three-phase AC power is output via the device wiring assembly 51 having the three device wiring members 1, but in FIG. 6, only one device wiring member 1 is shown. ing.

インバータケース６３は、図示しないグランド線により電気的に接地され、インバータ本体６２から放射される電磁波を遮断するように構成されている。インバータケース６３のコネクタ部６４に対応する部分には、開口６３ａが形成されている。 The inverter case 63 is electrically grounded by a ground wire (not shown), and is configured to block electromagnetic waves emitted from the inverter body 62. An opening 63a is formed in a portion of the inverter case 63 corresponding to the connector portion 64.

コネクタ部６４は、ボルト６５によってインバータケース６３に固定された導電性金属からなる固定部材６６と、固定部材６６に支持され、各機器用配線部材１のオス端子３ａを保持する絶縁性樹脂からなるインシュレータ６７と、を備えている。オス端子３ａは、インバータケース６３の開口６３ａを挿通され、その先端部がインシュレータ６７内に収容されている。 The connector portion 64 is made of a conductive metal fixing member 66 fixed to the inverter case 63 by bolts 65, and an insulating resin that is supported by the fixing member 66 and holds the male terminal 3 a of each device wiring member 1. And an insulator 67. The male terminal 3 a is inserted through the opening 63 a of the inverter case 63, and its tip is housed in the insulator 67.

インシュレータ６７は、オス端子３ａの全体を覆うように設けられると共に、オス端子３ａの先端よりも前方（図示右側）に突出するように設けられており、これにより、オス端子３ａへの人体等の不用意な接触を抑止するタッチプロテクト構造を実現している。このコネクタ部６４に、電気モータから延出されたワイヤハーネスを嵌合させることにより、ワイヤハーネスのメス端子にオス端子３ａが嵌合され、ワイヤハーネスを介して電気モータに三相交流電力が供給されることになる。 The insulator 67 is provided so as to cover the entire male terminal 3a, and is provided so as to project forward (to the right in the drawing) from the tip of the male terminal 3a. We have realized a touch protection structure that prevents inadvertent contact. By fitting the wire harness extended from the electric motor to the connector portion 64, the male terminal 3a is fitted to the female terminal of the wire harness, and three-phase AC power is supplied to the electric motor through the wire harness. Will be done.

各機器用配線部材１の圧着端子４ａは、インバータ本体６２の接続端子（バスバ端子）６８にボルト６９により固定され電気的に接続される。接続端子６８の圧着端子４ａを接続する接続部６８ａは、ワイヤハーネスのメス端子の嵌合方向に対して略垂直方向に延びるように形成されており、圧着端子４ａとオス端子３ａ間の撚線導体２は、略９０度屈曲（湾曲）されて配置される。 The crimp terminal 4a of each device wiring member 1 is fixed to a connection terminal (bus bar terminal) 68 of the inverter main body 62 by a bolt 69 to be electrically connected. The connection portion 68a for connecting the crimp terminal 4a of the connection terminal 68 is formed so as to extend in a direction substantially perpendicular to the fitting direction of the female terminal of the wire harness, and the twisted wire between the crimp terminal 4a and the male terminal 3a. The conductor 2 is arranged so as to be bent (curved) by approximately 90 degrees.

図示の例では、各機器用配線部材１を保持する保持部材５２が、インバータ本体６２から延出された支持部材７０に固定されている場合を示しているが、これに限らず、支持部材７０はインバータケース６３に固定されていてもよいし、保持部材５２が支持部材７０を介さず直接インバータ本体６２やインバータケース６３に支持される構造となっていてもよい。 In the illustrated example, the holding member 52 that holds the device wiring member 1 is fixed to the support member 70 extending from the inverter body 62, but the present invention is not limited to this. May be fixed to the inverter case 63, or the holding member 52 may be directly supported by the inverter body 62 or the inverter case 63 without the support member 70.

（実施の形態の作用及び効果）
以上説明したように、本実施の形態に係る機器用配線部材１では、撚線導体２の中央部２１（配線屈曲部）の子撚り線同士の撚りが両端側よりほぐれている。 (Operation and Effect of Embodiment)
As described above, in the device wiring member 1 according to the present embodiment, the twists of the child twisted wires of the central portion 21 (wiring bent portion) of the twisted wire conductor 2 are loosened from both ends.

これにより、子撚り線同士の撚りをほぐした中央部２１（配線屈曲部）にて撚線導体２を屈曲させやすくなり、たとえ、機器用配線部材１を短尺化しても、屈曲のし難さを低減することが可能になる。また、機器用配線部材１が屈曲し易くなることにより、配線作業における微調整がし易くなり、配線作業も容易になる。 This makes it easier to bend the stranded wire conductor 2 at the central portion 21 (wiring bent portion) where the twists of the child twisted wires are disentangled, and even if the wiring member 1 for equipment is shortened, it is difficult to bend it. Can be reduced. Further, since the device wiring member 1 is easily bent, fine adjustment in the wiring work is facilitated and the wiring work is facilitated.

さらに、機器用配線部材１では、２つの接続部３，４は、ワイヤハーネスのメス端子が嵌合され接続されるオス端子３ａと、機器の接続端子６８と接続される圧着端子４ａと、からなる。 Further, in the device wiring member 1, the two connecting portions 3 and 4 are composed of the male terminal 3a to which the female terminal of the wire harness is fitted and connected, and the crimp terminal 4a connected to the connecting terminal 68 of the device. Become.

このように構成することで、ワイヤハーネスのメス端子にオス端子３ａを嵌合する際に、撚線導体２における子撚り線同士の撚りがほぐれている中央部２１が調整部分となりオス端子３ａの動きを許容することが可能となり、嵌合時にオス端子３ａが少し動くことで、ワイヤハーネスのメス端子との接続性を向上させることが可能になる。 With this configuration, when the male terminal 3a is fitted to the female terminal of the wire harness, the central portion 21 where the twists of the child twisted wires of the twisted wire conductor 2 are loosened serves as an adjustment portion of the male terminal 3a. It is possible to allow the movement, and the male terminal 3a slightly moves at the time of fitting, so that the connectivity with the female terminal of the wire harness can be improved.
