［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]
Hereinafter, embodiments of the present invention will be described 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 wiring member for equipment for a vehicle (hereinafter, simply referred to as a wiring member for equipment) 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 equipment wiring member 1 includes a stranded conductor 2 in which a plurality of strands are twisted together, and two connecting portions 3 and 4 provided at both ends of the stranded 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 wiring member 1 for equipment is used for wiring in equipment of equipment mounted on a vehicle, and for example, a large current of 200 to 500A at the maximum is conducted. In the present embodiment, as an example, a case where the device wiring member 1 is used for the wiring inside the device of the inverter device that supplies the motor current to the electric motor for traveling 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 conductor 2 is, for example, a composite stranded wire obtained by twisting 17 strands (good electric conductors such as copper and aluminum) having an outer diameter of 0.32 mm to form a child stranded wire, and further twisting 19 of these stranded wires. It is a conductor, and the outer diameter of the entire stranded conductor 2 is, for example, 7.5 mm. Further, the twist pitch of the stranded conductor 2 (the interval along the longitudinal direction in which 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 conductor 2 is set according to the wiring length in the equipment to which the equipment wiring member 1 is applied, and is, for example, as short as 80 mm (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。 It is conceivable to use a single wire as the conductor of the wiring member 1 for equipment, but when a single wire having a large cross-sectional area is used, it becomes difficult to bend the wiring member 1 for equipment, and the wiring work is fine. It also makes adjustments difficult. That is, by using the stranded conductor 2 as the conductor of the wiring member 1 for equipment, it becomes easier to bend as compared with the case where a single wire is used, and fine adjustment at the time of wiring work becomes easy. Further, by using a stranded conductor 2 (composite stranded conductor) in which strands are twisted in advance, it is possible to integrally hold a large number of strands so that they do not fall apart, such as ultrasonic bonding described later. 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 periphery of the stranded conductor 2. In the present embodiment, since a large current is conducted through the stranded conductor 2 and the temperature becomes high, it is necessary to use an insulating tube 5 having excellent heat resistance. Specifically, as the insulating tube 5, it is desirable to use a tube having a heat resistance of about 150 ° C. to 200 ° C., and for example, a tube made of silicon 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 conductor 2 slides in the insulating tube 5 and the stranded conductor 2 can move freely to some extent. Details will be described later, but in the present embodiment, in order to untwist the child stranded wires in a part of the stranded conductor 2, a gap is formed between the stranded wires at the untied position (wiring bent portion) and the stranded conductor. 2 is in a state of bulging outward in the radial direction. The diameter of the insulating tube 5 is selected according to the outer shape (outer diameter) after the swelling in advance in consideration of the outward swelling of the stranded conductor 2 in the radial direction.

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 a nylon tube 5 is used, the thickness of the insulating tube 5 is preferably 2 mm or less. Further, from the viewpoint of ensuring the mechanical strength of the insulating tube 5 and maintaining the insulating performance, it is desirable that the thickness of the insulating tube 5 is 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 conductor 2 are exposed from the insulating tube 5, and connecting portions 3 and 4 are provided at both ends of the stranded 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 connection portions 3 and 4 include a male terminal 3a to which a female terminal of a wire harness (not shown) is fitted and connected, and a crimp terminal 4a to be connected to a connection 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 electric conductor, that is, a bus bar terminal, and the tip side thereof (the side opposite to the extending side of the stranded conductor 2) makes it easy to insert the wire harness into the female terminal. It is chamfered for this purpose.

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 for inserting the tip portion of the male terminal 3a, and is an elastic member or the like provided in the tubular portion. The pressing member is configured to press the male terminal 3a inserted into the tubular portion to electrically connect the male terminal 3a and the female terminal. Since the wire harness is gripped by the operator during wiring work, it has a touch protection structure so that the operator cannot directly touch the female terminal. By setting the wire harness side as a female terminal and the device side (device wiring member 1 side) as a male terminal 3a, it is possible to easily realize a touch protection 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 this embodiment, the male terminal 3a and the stranded conductor 2 are connected by ultrasonic bonding (ultrasonic welding). When ultrasonic bonding is performed, the strands (child stranded wires) of the stranded conductor 2 are bonded in a twisted state so as not to be separated.

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 plate-shaped connecting portion 41 in which the bolt hole 41a is formed and the base end side (extending side of the stranded conductor 2) of the connecting portion 41, and the stranded conductor 2 is crimped and fixed (caulked and fixed). ) Is integrally provided with a conductor fixing portion 42. The conductor fixing portion 42 is formed in a tubular shape, and by inserting (crushing) the conductor fixing portion 42 after inserting the end portion of the stranded conductor 2 into the hollow portion thereof, the stranded conductor 2 is fixed to the conductor fixing portion. It is configured to be crimp-fixed to 42. When crimping and fixing the stranded conductor 2, crimp and fix the stranded conductor 2 in a twisted state so that the strands (child stranded wires) of the stranded conductor 2 do not come apart.

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。 By the way, in the wiring member 1 for equipment according to the present embodiment, the central portion 21 of the stranded conductor 2 is a portion to be bent at the time of wiring, and the twist between the child stranded wires is unraveled from both ends. A portion (a part of the central portion 21) is included, and the wiring is bent (curved) at a predetermined angle at the bent portion of the wiring.

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 referred to here is a portion of the stranded conductor 2 on both ends (a portion having a fine twist pitch), that is, a portion excluding a portion near the connecting portions 3 and 4. The middle part excluding both ends. Further, FIG. 1 shows a case where the stranded conductor 2 is bent at a right angle (90 degrees) as an example, but the angle at which the stranded conductor 2 is bent is appropriately changed according to the wiring layout of the device and the like. 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 stranded conductor 2, when the twists of the child stranded wires are untwisted, a gap is created between the stranded wires at the position where the stranded wires are untwisted due to the influence of the bending habit (winding habit), and the stranded conductor 2 is in a state of bulging outward in the radial direction. By bending the stranded conductor 2 in this state, the child stranded conductor can move to the formed gap or outward and can be 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 conductor 2, but when the female terminal of the wire harness is fitted, the stranded conductor is connected. The central portion 21 (wiring bent portion) where the twists of the child stranded wires in 2 are untwisted serve as an adjusting portion, and the movement of the male terminal 3a can be allowed. The male terminal 3a moves a little at the time of fitting, so that the wire 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 of untwisting the child stranded wires, for example, a method of rotating (twisting) the stranded conductor 2 in a direction opposite to the twisting direction of the child stranded wires can be mentioned. In this case, the degree of untwisting of the child stranded wires can be adjusted by the amount of rotation (twisting angle) of the stranded conductor 2 when untwisting. The twist may be locally untwisted only in a part of the central portion 21 of the stranded conductor 2, or the twist may be loosely unraveled in substantially the entire central portion 21. That is, the twist may be unwound 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 untwisting of the child stranded wires in the central portion 21 of the stranded conductor 2 can be appropriately set according to the outer diameter and number of the strands and the child stranded wires, the bending angle, etc., but at least the stranded conductor In the state before bending 2 (the state where the stranded conductor 2 is linear), 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 untied). Flexibility can be improved by setting the value to 1.1 times or more of. The maximum outer diameter referred to here is the maximum width of the stranded conductor 2 when viewed from each position in the direction perpendicular to the longitudinal direction of the stranded conductor 2, that is, in the circumferential direction (on a plane arranged opposite to the observation direction). The maximum width of the projected image). When the stranded 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 sides A and B) is the maximum on both ends. It is preferable to configure it so that it is 1.3 times or more the outer diameter.

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 stranded conductors 2 are untwisted too much, the width (maximum outer diameter) of the stranded conductor 2 at the untwisted position (wiring bent portion) of the stranded conductors becomes large. Too much, when a plurality of device wiring members 1 are arranged in an aligned manner to form a device wiring assembly (described later), they interfere with each other of adjacent device wiring members 1 or with surrounding members such as a device case. There is a risk of wiring. Therefore, it is advisable to adjust the degree of untwisting of the child stranded wires so that the width (maximum outer diameter) does not interfere with the adjacent device wiring member 1 and surrounding members when applied to the device. From the viewpoint of suppressing interference with surrounding members, the maximum outer diameter of the stranded conductor 2 is the width of the male terminal 3a (thickness direction and extension direction of the stranded conductor 2 (female)) in the entire stranded conductor 2. It is desirable that the length is smaller than the length in the direction perpendicular to the mating 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 to which the stranded conductor 2 of the male terminal 3a is joined and the surface B of the connection portion 41 of the crimp terminal 4a to which the stranded conductor 2 is connected are on the same plane. The stranded conductor 2 is bent 90 degrees in the direction in which both sides A and B are close to each other to form the wiring member 1 for equipment. The 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 side opposite to the surface A of the male terminal 3a from the tip of the crimp terminal 4a. The distance W to the surface of the surface is, for example, 60 mm. The device wiring member 1 may be bent as long as it is provided in the device and used for wiring, and may not be bent in the unwired state. Further, the orientations of the surfaces A and B of both terminals 3a and 4a may be appropriately determined according to the arrangement of the connection terminals of the applicable device, and the orientations of the surfaces A and B of both terminals 3a and 4a are in the directions shown in the drawing. Not limited.

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 wiring member 1 for equipment for a vehicle is greatly affected by the vibration of the vehicle, the 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 wiring member 1 for equipment, vibration is transmitted from the wire harness to the wiring member 1 for equipment, the connection portion between the male terminal 3a and the stranded conductor 2 vibrates, and the male terminal 3a The corner portion C of the base end portion of the above may interfere with the stranded wire conductor 2 to cause 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 conductor 2 overlapped with 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 ultrasonic bonding portion). Here, an ultrasonic bonding portion 22 is formed at a position separated from the base end portion of the male terminal 3a (the end portion on the extending side of the stranded conductor 2) to the tip end side by a predetermined distance, and the corner portion C is super No ultrasonic bonding.

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 an ultrasonic bonding portion 22 on only a part of the stranded conductor 2 that overlaps with the male terminal 3a (a position separated from the base end portion of the male terminal 3a by a predetermined distance to the tip end side), As shown in FIG. 2B, when the stranded 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 stranded conductor 2 is twisted on the proximal end side of the ultrasonic bonding portion 22. 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 stranded conductor 2, and the stranded conductor 2 is 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, the corners can also be chamfered (rounded) at the end (position of the corner C) on the extension side of the stranded conductor 2 of the male terminal 3a. It is possible to suppress the interference between the portion C and the stranded conductor 2. In this case, the entire stranded conductor 2 that overlaps the male terminal 3a is formed as an ultrasonic bonding portion 22, and the connection strength between the male terminal 3a and the stranded conductor 2 can be further increased. Further, in this case, of the stranded conductor 2 overlapped with the male terminal 3a, only a part (a position separated from the base end portion of the male terminal 3a by a predetermined distance to the tip end side) is ultrasonically bonded. By forming the above, it is possible to further suppress the interference between the corner portion C and the stranded conductor 2, and further suppress defects such as disconnection of the stranded 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。 (Explanation of Manufacturing Method of Wiring Member 1 for Equipment)
Next, a method of manufacturing the wiring member 1 for equipment 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 wiring member 1 for equipment, 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 is linear. Further, at the time of ultrasonic bonding, bonding is performed while the entire wire is twisted so that the strands (child stranded wires) of the stranded conductor 2 are not separated.

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 device, and the ultrasonic horn is pressed against the stranded conductor 2 with the guide mold applied from the side of the stranded conductor 2 to obtain ultrasonic waves. Ultrasonically vibrate the horn. 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 phase welding state is created by the attractive force between the metal atoms, and the stranded conductor 2 and the male terminal 3a are joined.

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 so as 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。 After that, as shown in FIG. 4B, the other end of the stranded conductor 2 is inserted into the conductor fixing portion 42 of the crimp terminal 4a, and the conductor fixing portion 42 is deformed to deform the stranded conductor 2 into the crimp terminal 4a. It is 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 conductor 2 are connected by ultrasonic bonding, the crimp terminal 4a and the stranded 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 that vibration during ultrasonic bonding adversely affects the connection portion 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。 After that, as shown in FIG. 4C, the stranded conductor 2 is twisted in the direction opposite to the twisting direction of the child stranded wires. Then, in the central portion 21 of the stranded conductor 2, the twists between the child stranded wires are untied. At this time, since the stranded conductor 2 moves (rotates) in the insulating tube 5 and untwists the child stranded wires, the insulating tube 5 itself does not twist. After that, when the stranded conductor 2 is bent at the central portion 21 of the stranded conductor 2 in which the strands of the child stranded wires are untwisted, the wiring member 1 for equipment shown in FIG. 1 is obtained. In FIGS. 4A to 4C, the insulating tube 5 is shown by a alternate long and short dash 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 method of twisting the stranded conductor 2 is adopted in order to untwist the stranded conductor 2, the crimp terminal 4a has the stranded conductor 2 twisted and then both terminals 3a. The mounting angle is adjusted so that the surfaces A and B of 4a 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 (connection portion 41) are perpendicular to each other, the stranded conductor 2 is 90. By twisting the degree, both sides A and B are located on the same plane, but the mounting angle of the crimp terminal 4a can be adjusted as appropriate according to the desired twist angle (the degree of untwisting of the child stranded wires). Is. That is, it is possible to adjust the degree of untwisting of the child stranded wires of the stranded conductor 2 by the angle at the time of mounting the crimp terminal 4a (relative angle of the surfaces A and B).

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 conductor 2, both terminals 3a and 4a may be gripped and twisted, or any two positions of the stranded conductor 2 may be gripped and twisted. When both terminals 3a and 4a are gripped and twisted, in the vicinity of both terminals 3a and 4a, the stranded conductor 2 is fixed (joined or crimped) in a twisted state, so that the twist is hard to unravel, and the twist is hard to unravel. At a certain central portion 21, the twists of the child strands are loosened as a whole (gentlely). On the other hand, when the stranded conductor 2 is twisted by grasping the positions of any two positions, the twists between the child stranded wires are locally unwound at the portion between the two positions. Therefore, for example, when it is desired to make the bending radius at the time of bending smaller, the twisting of the child stranded wires is locally untwisted by grasping any two positions of the stranded conductor 2, and the entire central portion 21 is unwound. When the terminals 3a and 4a may be gripped and the twisted central portion 21 may be untwisted.

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, due to the influence of the bending habit (winding habit) of the stranded conductor 2, it is conceivable that even if the stranded conductor 2 is twisted, the twist may return to the tightening direction. In such a case, for example, after twisting the stranded conductor 2 significantly in the direction opposite to the twisting direction of the child stranded wires, the terminals 3a and 4a are twisted in the same direction as the twisting direction until the positions where the terminals 3a and 4a have a desired positional relationship. You may try to return it. Further, after twisting the stranded conductor 2 to a position where both terminals 3a and 4a have a desired positional relationship, a pressing force is applied to the stranded conductor 2 with a jig or the like to crush a part of the stranded conductor 2. As a result, 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 where the stranded conductor 2 is twisted after connecting both terminals 3a and 4a to untwist the child stranded wires has been described, but the present invention is not limited to this, and one end of the stranded conductor 2 is over. After connecting to the male terminal 3a by ultrasonic bonding, the stranded conductor 2 may be bent, and after the stranded conductor 2 is bent, the crimp terminal 4a may be connected to the other end of the stranded 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 conductor 2 is bent with one end of the stranded conductor 2 connected to the male terminal 3a, the stranded conductor 2 is affected by the tensile or compressive stress acting on each wire when the stranded conductor 2 is bent. The twists between the child stranded wires of the conductor 2 are naturally untied. After that, the crimp terminal 4a is connected to the other end of the stranded conductor 2, but when the stranded conductor 2 is bent, the ends of the strands (child stranded wires) are not aligned at the other end of the stranded conductor 2. After partially cutting off the other end of the stranded conductor 2 to align the ends of the strands (child stranded wires), the crimp terminal 4a may be crimped and fixed to the other end of the stranded 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, from the central portion 21 of the stranded conductor 2 to the crimp terminal 4a side, the twists of the child stranded wires are gently untwisted. More specifically, since the stranded conductor 2 has a bending habit (winding habit), the twist between the child stranded wires is most unraveled at the central portion 21 (bending portion) having a smaller bending radius, and the crimp terminal 4a The closer to, the tighter the twist (not unraveled).

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 loosening of the child stranded wires of the stranded conductor 2 and suppress an increase in the width (maximum outer diameter) of the stranded conductor 2. Further, by providing the crimp terminal 4a with the stranded conductor 2 bent, each strand (each child stranded wire) is crimped and fixed in the bent state, so that the stranded conductor 2 is bent. It becomes 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 device wiring members 1 for a plurality of vehicles 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 on the assumption that three-phase AC power is transmitted will be described, but the number of wiring members 1 for equipment is not limited to this, and two or four. It may be the above.

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 a 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 portion of the holding member 52 that comes into contact with the equipment wiring member 1 may be made of an insulating resin, and the portion that does not come into contact with the equipment wiring member 1 may be made of metal.

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 wiring member 1 for equipment are formed, and is formed in a substantially comb-teeth shape. By accommodating the wiring member 1 for each device in the notch 53, the wiring member 1 for the device is held at a predetermined interval.

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 for holding the three wiring members 1 for equipment is formed here, a plurality of holding members configured to hold the distance between the wiring members 1 for equipment adjacent to each other 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 wiring assembly 51 for equipment according to the present embodiment, the holding member 52 is not provided at the central portion 21 of the stranded conductor 2, but is provided at the end side of the stranded conductor 2 near the crimp terminal 4a side. ing. As a result, the wiring member 1 for each device is held by the holding member 52, facilitating the wiring work of the wiring member 1 for the device, and the stranded conductor 2 (of the child stranded wires) on the male terminal 3a side of the holding member 52. The untwisted central portion 21) serves as an adjusting portion, and it becomes possible to allow the movement of the male terminal 3a, and it becomes possible to improve the connectivity when fitting the female terminal of the wire harness.

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。 FIG. 5 shows a 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. However, the wiring layout of the device to be applied is shown. The spacing between the wiring members 1 for each device may be different depending on the situation. In this case, since a common wire harness is connected to the male terminal 3a of the wiring member 1 for each device, the position of the male terminal 3a is fixed according 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 conductor 2 on the crimp terminal 4a side) will be adjusted as appropriate.

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, FIG. 5 shows a case where the lengths of the three wiring members 1 for equipment (the length of the stranded conductor 2) are the same, but the length of the wiring member 1 for equipment (the length of the stranded conductor 2) is the same. ) May be different. Also in this case, since a common wire harness is connected to the male terminal 3a of the wiring member 1 for each device, the position of the male terminal 3a is a fixed position according to the position of the female terminal of the wire harness. Therefore, the position on the crimp terminal 4a side (position in the vertical direction in the drawing), the bending angle of the stranded conductor 2, and the like are appropriately adjusted.

（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。 (Example of application to equipment)
Next, a specific arrangement and the like when the equipment wiring member 1 (equipment wiring assembly 51) is applied to the inverter device of the 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 the wiring inside the device of the inverter device 61 of the 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 an inverter main body 62 having a switching element such as a plurality of power transistors, a flywheel diode, and the like, an inverter case 63 made of a conductive metal such as aluminum that houses the inverter main body 62, and an inverter case 63. It is configured to include a connector portion 64 and the like.

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 ON / OFF state of the switching element, and output the converted AC power via the connector unit 64. In the present embodiment, the 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 of the device wiring members 1 is illustrated. 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 radiated from the inverter main 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 fixing member 66 made of a conductive metal fixed to the inverter case 63 by a bolt 65, and an insulating resin supported by the fixing member 66 and holding the male terminal 3a of the wiring member 1 for each device. It is equipped with an insulator 67. The male terminal 3a is inserted through the opening 63a of the inverter case 63, and the tip portion thereof 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 protrudes forward (on the right side in the drawing) from the tip of the male terminal 3a, whereby the human body or the like to the male terminal 3a can be provided. A touch protection structure that suppresses inadvertent contact is realized. By fitting the wire harness extending from the electric motor into 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 via 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 the wiring member 1 for each device is fixed to the connection terminal (bus bar terminal) 68 of the inverter main body 62 by a bolt 69 and electrically connected. The connection portion 68a for connecting the crimp terminal 4a of the connection terminal 68 is formed so as to extend substantially perpendicular to the fitting direction of the female terminal of the wire harness, and the stranded 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 wiring member 1 for each device is fixed to the support member 70 extending from the inverter main body 62, but the present invention is not limited to this, and the support member 70 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 main 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。 (Actions and effects of embodiments)
As described above, in the wiring member 1 for equipment according to the present embodiment, the twists between the child stranded wires in the central portion 21 (wiring bent portion) of the stranded conductor 2 are untied 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。 As a result, the stranded conductor 2 can be easily bent at the central portion 21 (wiring bending portion) where the twists of the child stranded wires are untwisted, and even if the wiring member 1 for equipment is shortened, it is difficult to bend. Can be reduced. Further, since the wiring member 1 for equipment is easily bent, fine adjustment in wiring work is facilitated, and wiring work is also 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 wiring member 1 for equipment, the two connection portions 3 and 4 consist of a male terminal 3a to which a female terminal of a wire harness is fitted and connected, and a crimp terminal 4a connected to a connection terminal 68 of the equipment. 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 stranded wires in the stranded conductor 2 are untwisted becomes the adjusting portion of the male terminal 3a. The movement can be allowed, and the male terminal 3a moves a little at the time of fitting, so that the connectivity of the wire harness with the female terminal can be improved.
