Description

本発明は、端子金具付き編組線および端子金具付き編組線の製造方法に関する。   The present invention relates to a braided wire with terminal metal fittings and a method for manufacturing a braided wire with terminal metal fittings.

従来、ボルトを締結するための締結端子が接続された金属製の編組線として、下記特許文献１に記載のものが知られている。編組線は、金属素線を筒状に編み込むことにより帯状に形成されており、締結端子は、編組線の端末を金属板材の上に重ね合わせ、この金属板材の両端を互いに突き合わせるようにプレスして折り返した後、金属板材をさらにプレスすることで編組線の端末に締結端子を形成している。   Conventionally, the thing of the following patent document 1 is known as a metal braided wire to which the fastening terminal for fastening a volt | bolt was connected. The braided wire is formed in a band shape by braiding metal strands into a cylindrical shape, and the fastening terminal is pressed so that the ends of the braided wire overlap each other on the metal plate and both ends of this metal plate are butted against each other Then, after being folded, the metal plate material is further pressed to form a fastening terminal at the end of the braided wire.

特開平８−１５３５６１号公報JP-A-8-153561

ところで、上記のような編組線を、底板の幅方向両側縁から立ち上がり形成された一対のバレル片を有する端子金具に接続する場合には、一対のバレル片の間に編組線の端末を挿入して底板に編組線を載置し、両バレル片を編組線に対して圧着する。
ところが、編組線は、細い金属素線を編み込んで形成されていることから、編組線の端末では、金属素線が編み込む前の状態に戻ろうとすることで、金属素線がほつれてしまい、編組線の他の部分に比べて、嵩張った状態になってしまう。
このため、金属素線がほつれた状態の編組線の端末を一対のバレル片の間に挿入して、両バレル片を編組線に圧着しようとすると、バレル片とバレル片との間からほつれた金属素線がはみ出すなど編組線に対してバレル片を圧着しづらく、編組線にバレル片を圧着させる作業性が低下してしまう。 By the way, when connecting the braided wire as described above to a terminal fitting having a pair of barrel pieces formed upright from both side edges of the bottom plate, the end of the braided wire is inserted between the pair of barrel pieces. Then, place the braided wire on the bottom plate and press both barrel pieces against the braided wire.
However, since the braided wire is formed by weaving thin metal strands, at the end of the braided wire, trying to return to the state before the metal strands are braided, the metal strands are frayed, and the braided wire Compared to other parts of the line, it becomes bulky.
For this reason, when the end of the braided wire with the metal strands frayed was inserted between a pair of barrel pieces and both barrel pieces were to be crimped to the braided wire, they frayed from between the barrel pieces and the barrel pieces. It is difficult to press the barrel piece against the braided wire such as the metal wire sticking out, and the workability of pressing the barrel piece against the braided wire is lowered.

本発明は上記のような事情に基づいて完成されたものであって、編組線に端子金具を圧着する作業性を向上させると共に、金属素線のほつれのない端子金具付き編組線を提供することを目的とする。   The present invention has been completed based on the above circumstances, and provides a braided wire with a terminal fitting that improves the workability of crimping the terminal fitting to the braided wire and does not fray metal strands. With the goal.

上記の目的を達成するための手段として本発明は、複数の金属素線からなる編組線の端末に端子金具が圧着されて接続された端子金具付き編組線であって、前記編組線の端末には、前記金属素線を密集させて束ねた被圧着部が形成されており、前記被圧着部には、前記端子金具に設けられたバレルが圧着されているところに特徴を有する。
また、本発明は、複数の金属素線からなる編組線に端子金具が圧着されて接続される端子金具付き編組線の製造方法であって、前記編組線の前記金属素線同士もしくは前記金属素線の表面に形成されためっき層同士を接合させて被圧着部を形成する被圧着部形成工程と、前記端子金具に設けられたバレルを前記被圧着部形成工程により形成された被圧着部に圧着する圧着工程とを備えているところに特徴を有する。 As a means for achieving the above object, the present invention provides a braided wire with a terminal metal fitting connected to a terminal of a braided wire composed of a plurality of metal strands, the terminal metal wire being connected to the terminal of the braided wire. Is characterized in that a crimped portion in which the metal strands are densely bundled is formed, and a barrel provided on the terminal fitting is crimped to the crimped portion.
Further, the present invention is a method of manufacturing a braided wire with terminal metal fittings in which a terminal metal fitting is crimped and connected to a braided wire composed of a plurality of metal strands, wherein the metal strands of the braided wires or the metal element A bonded portion forming step of bonding the plating layers formed on the surface of the wire to form a bonded portion; and a barrel provided in the terminal fitting on the bonded portion formed by the bonded portion forming step. And a crimping process for crimping.

このような構成の端子金具付き編組線によると、金属素線がほつれずに束ねられた状態の被圧着部にバレルを圧着することができるので、バレルの圧着作業をし易くすることができる。また、圧着されたバレルから金属素線がほつれてはみ出すことがなく、見た目をよくすることができる。   According to the braided wire with a terminal fitting having such a configuration, the barrel can be crimped to the crimped portion in a state where the metal strands are bundled without fraying, and thus the crimping operation of the barrel can be facilitated. In addition, the metal strand does not fray from the crimped barrel, and the appearance can be improved.

本発明の実施の態様として、以下の構成が好ましい。
前記被圧着部は、前記金属素線同士もしくは前記金属素線の表面に形成されためっき層同士を接合させることで形成されている構成が好ましい。
このような構成によると、一般に用いられる超音波溶接や抵抗溶接などによって、被圧着部を容易に形成することができる。 The following configuration is preferable as an embodiment of the present invention.
The structure to which the said to-be-crimped part is formed is joined by joining the said metal strands or the plating layers formed in the surface of the said metal strand.
According to such a structure, a to-be-compressed part can be easily formed by ultrasonic welding, resistance welding, etc. which are generally used.

前記被圧着部における外周の長さ寸法は、前記編組線における前記被圧着部とは異なる部分の外周の長さ寸法よりも小さく形成されている構成としてもよい。
このような構成によると、被圧着部が編組線の他の部分よりも細くなっているので、被圧着部をバレルにさらに配しやすくすることができる。これにより、端子金具に対するバレルの組み付け作業性を向上させることができる。 The length dimension of the outer periphery in the said to-be-bonded part is good also as a structure formed smaller than the length dimension of the outer periphery of the part different from the said to-be-bonded part in the said braided wire.
According to such a structure, since the to-be-bonded part is thinner than the other part of the braided wire, the to-be-bonded part can be further easily arranged on the barrel. Thereby, the assembly | attachment workability | operativity of the barrel with respect to a terminal metal fitting can be improved.

前記めっき層は、錫めっき層であって、前記被圧着部は、前記金属素線の前記めっき層同士が超音波振動により溶着されて形成されている構成にしてもよい。
一般に、錫同士は、超音波溶着技術を適用しても、溶着し難い。このため、上記のような構成によると、被圧着部にワイヤバレルを圧着する際に、錫めっき層同士が溶着された部分が容易に破断され、被圧着部をバレルの形状に追従させて変形させることができる。これにより、バレルと被圧着部との接続状態を良好にすることができる。 The plating layer may be a tin plating layer, and the pressure-bonded portion may be formed by welding the plating layers of the metal strands by ultrasonic vibration.
Generally, tin is difficult to weld even if an ultrasonic welding technique is applied. For this reason, according to the above configuration, when the wire barrel is crimped to the crimped portion, the portion where the tin plating layers are welded is easily broken, and the crimped portion is deformed by following the shape of the barrel. Can be made. Thereby, the connection state of a barrel and a to-be-bonded part can be made favorable.

前記被圧着部形成工程において、前記被圧着部は、前記編組線の中間部分における前記金属素線同士もしくは前記金属素線の表面に形成されためっき層同士を接合して束ねて、この束ねて溶着された溶着部分を前記編組線の延出された方向と交差する方向に切断することにより切断された前記編組線の両端末にそれぞれ形成されている構成としてもよい。
このような構成によると、編組線の中間部分の一部を溶着によって束ねて、その束ねて溶着された溶着部分を切断することで、一度に２つの被圧着部を形成することができる。また、編組線をコンベアなどの搬送装置によって搬送しながら、溶着作業と切断作業とを繰り返すことで被圧着部を連続して形成することができる。これにより、編組線の端末に被圧着部を個別に形成する場合に比べて、被圧着部を形成する作業性を飛躍的に向上させることができる。 In the to-be-bonded part forming step, the to-be-bonded part is formed by bonding and bundling the metal strands or plating layers formed on the surface of the metal strands in the middle part of the braided wire. It is good also as a structure currently formed in the both ends of the said braided wire cut | disconnected by cut | disconnecting the welded part welded in the direction which cross | intersects the direction where the said braided wire was extended.
According to such a configuration, a part of the intermediate portion of the braided wire is bundled by welding, and the two welded portions can be formed at a time by cutting the welded portion that is bundled and welded. Moreover, a to-be-bonded part can be continuously formed by repeating a welding operation | work and a cutting | disconnection operation | work, conveying a braided wire with conveying apparatuses, such as a conveyor. Thereby, the workability | operativity which forms a to-be-crimped part can be improved dramatically compared with the case where a to-be-crimped part is individually formed in the terminal of a braided wire.

本発明によれば、編組線に端子金具を圧着する作業性を向上させると共に、金属素線のほつれのない端子金具付き編組線を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, while improving the workability | operativity which crimps | bonds a terminal metal fitting to a braided wire, the braided wire with a terminal metal fitting which does not fray a metal strand can be provided.

＜実施形態＞
本発明の実施形態について、図１乃至図６を参照して説明する。
本実施形態は、図１に示すように、編組線２０の端末に丸形端子（「端子金具」の一例）３０を電気的に接続した端子金具付き編組線１０を例示している。
編組線２０は、導電性に優れた細い複数の金属素線２１を網目状に編み込んで形成されており、筒状をなしている。金属素線２１の表面には、錫めっきが施されることで錫めっき層（図示省略）が形成されており、金属素線２１の酸化や錆の発生が抑制されている。編組線２０の端末には、金属素線２１を密集させて束ねた被圧着部２２が形成されている。被圧着部２２は、金属素線２１の表面に形成された錫めっき層同士を超音波振動によって溶着させることで一束にまとめられた中実形状とされており、被圧着部２２の外周寸法は、被圧着部２２とは異なる位置の編組線（例えば編組線の中央部分２４）の外周寸法よりも小さく形成されている。 <Embodiment>
An embodiment of the present invention will be described with reference to FIGS. 1 to 6.
In the present embodiment, as shown in FIG. 1, a braided wire 10 with a terminal fitting in which a round terminal (an example of a “terminal fitting”) 30 is electrically connected to the end of the braided wire 20 is illustrated.
The braided wire 20 is formed by braiding a plurality of thin metal wires 21 having excellent conductivity into a mesh shape, and has a cylindrical shape. A tin plating layer (not shown) is formed on the surface of the metal strand 21 by performing tin plating, and oxidation of the metal strand 21 and generation of rust are suppressed. At the end of the braided wire 20, a pressure-bonded portion 22 in which metal strands 21 are densely bundled is formed. The to-be-crimped part 22 is made into the solid shape put together by bundle-bonding the tin plating layers formed in the surface of the metal strand 21 by ultrasonic vibration, The outer periphery dimension of the to-be-crimped part 22 Is formed to be smaller than the outer peripheral dimension of the braided wire (for example, the central portion 24 of the braided wire) at a position different from the crimped portion 22.

丸形端子３０は、導電性に優れた金属板材をプレス加工して形成されており、略円形平板状の接続部３１と、接続部３１の後方に接続部３１と一体に形成されたバレル３２とを備えて構成されている。
接続部３１には、同接続部３１を上下方向（板厚方向）に貫通する丸孔３３が形成されており、この丸孔３３にボルトなどの締結部材（図示せず）を挿通させることができるようになっている。
バレル３２は、図１、図５及び図６に示すように、いわゆるオープンバレル型であって、接続部３１から後方に延出された底板３４と、この底板３４に載置された被圧着部２２に圧着される一対のバレル片３５とを備えて構成されている。 The round terminal 30 is formed by pressing a metal plate excellent in conductivity, and includes a connection part 31 having a substantially circular flat plate shape and a barrel 32 formed integrally with the connection part 31 behind the connection part 31. And is configured.
The connection portion 31 is formed with a round hole 33 penetrating the connection portion 31 in the vertical direction (plate thickness direction), and a fastening member (not shown) such as a bolt can be inserted into the round hole 33. It can be done.
As shown in FIGS. 1, 5 and 6, the barrel 32 is a so-called open barrel type, and includes a bottom plate 34 extending rearward from the connection portion 31, and a pressure-bonded portion placed on the bottom plate 34. 22 and a pair of barrel pieces 35 to be crimped to 22.

底板３４の断面は、上方に向かって僅かに湾曲する凹形状をなしており、凹形状の底板３４の内側には、編組線２０の被圧着部２２が載置されている。
一対のバレル片３５は、被圧着部２２に圧着される前の状態では、底板３４の幅方向両側縁から上方に立ち上がった形態をなしており、被圧着部２２に圧着されることで、図１および図２に示すように、底板３４に載置された被圧着部２２の軸心に一対のバレル片３５の端部３５Ａを食い込ませて、一対のバレル片３５と被圧着部２２とが密着した状態となっている。また、圧着された一対のバレル片３５の前後両端部からは被圧着部２２が露出した状態となっており、前後両端部から露出した被圧着部２２は、バレル片３５が圧着されることで変形しているものの、金属素線２１は溶着して束ねられた状態のままとなっている。 The cross section of the bottom plate 34 has a concave shape that is slightly curved upward, and the crimped portion 22 of the braided wire 20 is placed inside the concave bottom plate 34.
The pair of barrel pieces 35 are in a state of rising upward from both side edges in the width direction of the bottom plate 34 before being crimped to the crimped portion 22, and are crimped to the crimped portion 22. As shown in FIG. 1 and FIG. 2, the end portions 35 </ b> A of the pair of barrel pieces 35 are bitten into the axial center of the crimped portion 22 placed on the bottom plate 34, so that the pair of barrel pieces 35 and the crimped portion 22 are It is in close contact. Moreover, the to-be-bonded portion 22 is exposed from the front and rear end portions of the pair of pressure-bonded barrel pieces 35, and the to-be-bonded portion 22 exposed from both the front and rear end portions is bonded to the barrel piece 35. Although deformed, the metal strand 21 remains welded and bundled.

次に、端子金具付き編組線１０を製造する製造方法を説明する。
端子金具付き編組線１０は、図３乃至図６に示すように、編組線２０の端末に被圧着部２２を形成する被圧着部形成工程と、この被圧着部形成工程によって形成された被圧着部２２に丸形端子３０を圧着する圧着工程とを行うことで製造される。 Next, the manufacturing method which manufactures the braided wire 10 with a terminal metal fitting is demonstrated.
As shown in FIGS. 3 to 6, the braided wire with terminal fitting 10 is formed by a crimped portion forming step for forming a crimped portion 22 at the end of the braided wire 20 and a crimped portion formed by the crimped portion forming step. It is manufactured by performing a crimping process for crimping the round terminal 30 to the portion 22.

被圧着部形成工程では、まず、編組線２０の延出方向における中間部分の金属素線２１を密集させた状態で超音波溶着装置（図示せず）に配し、超音波振動によって金属素線２１の錫めっき層同士を溶着させて、金属素線２１を中実に一束にまとめた溶着部分２３を形成する。詳細には、超音波溶着装置によって編組線２０に超音波振動を与えると、密集された金属素線２１の錫めっき層同士が擦れ合い、摩擦熱によって錫めっき層が溶解する。その後、超音波振動を停止し、金属素線２１が冷却されることにより、図３に示すように、編組線２０の中間部分において、金属素線２１が密集して束ねられた溶着部分２３が形成される。   In the to-be-bonded part forming step, first, the metal strands 21 in the intermediate portion in the extending direction of the braided wire 20 are arranged in a dense state in an ultrasonic welding apparatus (not shown), and the metal strands are ultrasonically vibrated. 21 tin plating layers are welded together to form a welded portion 23 in which the metal strands 21 are solidly bundled. Specifically, when ultrasonic vibration is applied to the braided wire 20 by the ultrasonic welding apparatus, the tin plating layers of the dense metal element wires 21 are rubbed with each other, and the tin plating layer is melted by frictional heat. Thereafter, the ultrasonic vibration is stopped and the metal strand 21 is cooled, so that a welded portion 23 in which the metal strands 21 are densely bundled and bundled is formed in the middle portion of the braided wire 20 as shown in FIG. It is formed.

次に、図４に示すように、金属素線２１が密集して束ねられた溶着部分２３を編組線２０が延出された方向と略直交する方向に切断する。詳細には、溶着部分２３を切断装置５０上に配し、上方に配されたカッター部５１を溶着部分２３の中間位置に降下させることで、溶着部分２３を編組線２０が延出された方向と略直交する方向に切断する。これにより、切断された編組線２０の両端末に、編組線２０の他の部分よりも小径に形成された略円柱形状の被圧着部２２がそれぞれ形成される。   Next, as shown in FIG. 4, the welded portion 23 in which the metal strands 21 are densely bundled is cut in a direction substantially orthogonal to the direction in which the braided wire 20 is extended. Specifically, the welded portion 23 is disposed on the cutting device 50, and the cutter portion 51 disposed above is lowered to an intermediate position of the welded portion 23, whereby the welded portion 23 is extended in the direction in which the braided wire 20 is extended. And cut in a direction substantially orthogonal to Thereby, the substantially cylindrical press-bonded portions 22 each having a smaller diameter than the other portions of the braided wire 20 are formed at both ends of the cut braided wire 20.

すなわち、被圧着部形成工程では、編組線２０の中間部分である１カ所を小径に束ねた状態に溶着させて、この溶着部分２３を切断することで、一度に２つの被圧着部２２を形成することができる。また、編組線２０をコンベアなどの搬送装置によって、編組線を編組線が延出された方向に搬送しながら、この溶着作業と切断作業とを繰り返すことにより、編組線２０の端末に被圧着部２２を連続して形成することができる。これにより、編組線の端末に被圧着部を個別に形成する場合に比べて、被圧着部２２を形成する作業性を飛躍的に向上させることができる。   That is, in the to-be-bonded portion forming step, two portions to be bonded 22 are formed at a time by welding one portion, which is an intermediate portion of the braided wire 20, in a bundled state with a small diameter and cutting the welded portion 23. can do. In addition, by repeating the welding operation and the cutting operation while conveying the braided wire 20 in a direction in which the braided wire is extended by a conveying device such as a conveyor, a portion to be pressed is attached to the end of the braided wire 20. 22 can be formed continuously. Thereby, the workability | operativity which forms the to-be-crimped part 22 can be improved greatly compared with the case where the to-be-crimped part is formed separately in the terminal of a braided wire.

図５に示すように、編組線２０の端末に被圧着部２２が形成されたところで、この被圧着部２２に丸形端子３０のバレル３２を圧着する圧着工程を行う。
圧着工程では、まず、一対のバレル片３５が上方に立ち上がった状態の丸形端子３０をアンビル（図示省略）上に位置決めして配置する。そして、丸形端子３０がアンビルに配置されたところで、図６に示すように、編組線被圧着部を一対のバレル片の間に挿入し、底板上に被圧着部を載置する。なお、図６においては、バレル３２の底板３４上に被圧着部２２が載置された状態を分かりやすくするために、アンビルを図示省略している。 As shown in FIG. 5, when the crimped portion 22 is formed at the end of the braided wire 20, a crimping process for crimping the barrel 32 of the round terminal 30 to the crimped portion 22 is performed.
In the crimping step, first, the round terminal 30 with the pair of barrel pieces 35 rising upward is positioned and arranged on the anvil (not shown). Then, when the round terminal 30 is disposed on the anvil, as shown in FIG. 6, the braided wire crimping portion is inserted between the pair of barrel pieces, and the crimping portion is placed on the bottom plate. In FIG. 6, the anvil is not shown in order to make it easy to understand the state in which the bonded portion 22 is placed on the bottom plate 34 of the barrel 32.

ところで、一般に、編組線は、細い金属素線を網目状に編み込んで形成されていることから、編組線を切断すると、編組線の端末では、金属素線が編み込む前の状態に戻ろうとすることで、金属素線がほつれてしまい、編組線の他の部分に比べて、嵩張った状態になってしまう。このため、切断した状態のままの編組線の端末を一対のバレル片の間に配して一対のバレル片を編組線に圧着しようとすると、バレル片とバレル片との間からほつれた金属素線がはみ出すなど、編組線に対してバレル片を圧着しづらく、編組線にバレル片を圧着する圧着作業の作業性が低下してしまう。
ところが、本実施形態によると、編組線２０の端末には、金属素線２１がほつれないように小径に束ねられた被圧着部２２が形成されているので、一対のバレル片３５の間に編組線２０の端末を配し易く、底板３４上に編組線２０の端末を配置する作業性を向上させることができるようになっている。 By the way, in general, the braided wire is formed by braiding thin metal strands in a mesh shape. Therefore, when the braided wire is cut, the end of the braided wire attempts to return to the state before the metal strands are knitted. Thus, the metal strands are frayed and become bulky as compared with other portions of the braided wire. For this reason, when the end of the braided wire that has been cut is disposed between the pair of barrel pieces and the pair of barrel pieces are to be crimped to the braided wire, the metal element loosened from between the barrel pieces and the barrel pieces It is difficult to press the barrel piece against the braided wire, for example, the wire sticks out, and the workability of the crimping operation to press the barrel piece against the braided wire is lowered.
However, according to the present embodiment, the end of the braided wire 20 is formed with the crimped portion 22 bundled in a small diameter so that the metal strands 21 are not frayed. The terminal of the wire 20 can be easily arranged, and the workability of arranging the terminal of the braided wire 20 on the bottom plate 34 can be improved.

そして、バレル３２の底板３４上に被圧着部２２が載置されたところで、アンビル及び丸形端子３０の上方に配されたクリンパ（図示せず）を下降させる。すると、一対のバレル片３５の端部３５Ａを被圧着部２２の軸心に向かって食い込ませるようにして一対のバレル片３５が被圧着部２２に対して圧着され、図１に示すように、編組線２０の端末に丸形端子３０が電気的に接続された端子金具付き編組線１０が完成する。   And when the to-be-compressed part 22 is mounted on the bottom plate 34 of the barrel 32, the crimper (not shown) arranged above the anvil and the round terminal 30 is lowered. Then, the pair of barrel pieces 35 are crimped to the crimped portion 22 so that the end portions 35A of the pair of barrel pieces 35 are bitten toward the axial center of the crimped portion 22, and as shown in FIG. The braided wire with terminal fitting 10 in which the round terminal 30 is electrically connected to the end of the braided wire 20 is completed.

以上のように本実施形態によると、編組線２０の端末に金属素線２１がほつれないように小径に束ねられた被圧着部２２が形成されているので、一対のバレル片３５の間から金属素線２１をはみ出させることなく、編組線２０の端末をバレル３２の底板３４上に配してバレル片３５を被圧着部２２に圧着させることができる。すなわち、切断したままの状態の編組線の端末にバレル片を圧着する場合に比べて、編組線２０に対して丸形端子３０を圧着する圧着工程の作業性を飛躍的に向上させることができる。また、被圧着部２２は、バレル片３５が圧着された後も、金属素線２１が大きくほつれることなく密集して束ねられた状態のままの形状をしているので、見た目もきれいに仕上げることができる。   As described above, according to the present embodiment, the crimped portion 22 bundled in a small diameter is formed at the end of the braided wire 20 so that the metal strand 21 is not frayed. Without protruding the strand 21, the end of the braided wire 20 can be disposed on the bottom plate 34 of the barrel 32 and the barrel piece 35 can be crimped to the crimped portion 22. That is, the workability of the crimping process for crimping the round terminal 30 to the braided wire 20 can be dramatically improved as compared with the case where the barrel piece is crimped to the end of the braided wire that is still cut. . Moreover, since the to-be-crimped part 22 has the shape in which the metal strands 21 are closely packed and bundled without being greatly frayed after the barrel piece 35 is crimped, the appearance is also finished finely. Can do.

また、本実施形態によると、バレル片３５を圧着した際に、被圧着部２２がバレル片３５の形状に合わせて追従するように、錫めっき層同士を超音波振動によって溶着しているので、バレル３２と被圧着部２２との接続状態を良好にすることができ、編組線２０にバレル３２を有する丸形端子３０を圧着する際に非常に有効である。   In addition, according to the present embodiment, when the barrel piece 35 is crimped, the tin plating layers are welded by ultrasonic vibration so that the bonded portion 22 follows the shape of the barrel piece 35, so The connection state between the barrel 32 and the part to be crimped 22 can be improved, which is very effective when the round terminal 30 having the barrel 32 is crimped to the braided wire 20.

また、本実施形態では、端子金具付き編組線１０の製造時においても、編組線２０の中間部分の一部に金属素線２１を密集して１つに束ねた溶着部分２３を形成し、その溶着部分２３を２つに切断することで、一度に２つの被圧着部２２を切断された編組線２０の両端末にそれぞれ形成することができる。さらに、編組線２０を搬送装置などによって搬送しながら、この溶着作業と切断作業とを繰り返して行うことで、編組線２０の端末に被圧着部２２を連続して形成することができる。これにより、編組線の端末に被圧着部を個別に形成する場合に比べて、被圧着部２２を形成する被圧着部形成工程の作業性を飛躍的に向上させることができる。   Further, in the present embodiment, even when the braided wire 10 with terminal fittings is manufactured, a welded portion 23 is formed in which the metal strands 21 are densely bundled and bundled together in a part of the intermediate portion of the braided wire 20, By cutting the welded portion 23 in two, two crimped portions 22 can be formed at both ends of the braided wire 20 cut at a time. Further, by repeatedly performing this welding operation and cutting operation while conveying the braided wire 20 by a conveying device or the like, the crimped portion 22 can be continuously formed at the end of the braided wire 20. Thereby, the workability | operativity of the to-be-bonded part formation process which forms the to-be-bonded part 22 can be improved dramatically compared with the case where the to-be-bonded part 22 is individually formed in the terminal of a braided wire.
