Here, the extension direction X, width direction Y, and vertical direction Z are substantially orthogonal to each other. The extension direction X corresponds to the direction in which the electric wire W to which the terminal 1 is connected extends, one being the front side (front end side) and the other being the back side (rear end side). The width direction Y and the vertical direction Z correspond to cross directions that intersect with the extension direction X, and one of them in the vertical direction Z is called the upper side, and the other is called the lower side.

電線Wは、図1から図4に示すように、導電性を有する線状の導体部W1と、当該導体部W1の外側を覆う絶縁性の被覆部W2と、を含んで構成される。電線Wは、被覆部W2で導体部W1を被覆した絶縁電線である。導体部W1は、導電性の金属である、銅や、銅合金、アルミニウム、アルミニウム合金等の素線を複数束ねた芯線や、複数の素線を撚り合わせた撚り芯線として構成される。被覆部W2は、導体部W1の外周側を被覆する電線被覆である。被覆部W2は、絶縁性の樹脂材料である、PP(Polypropylene)や、PVC(polyvinyl chloride)、架橋PE(polyethylene)等を押出成形することによって形成される。被覆部W2を構成する絶縁性の樹脂材料は、耐摩耗性や、耐薬品性、耐熱性等に配慮して適宜選定される。電線Wは、その先端において、被覆部W2が剥ぎ取られて導体部W1の先端部が被覆部W2の先端から露出して形成される。端子付電線100は、この導体部W1が露出している電線Wの先端に端子1が接続される。実施形態の電線Wは、図1に示すように、線状の延在方向Xと交差する方向の断面形状において導体部W1が略円形状、被覆部W2が略円環形状となっており全体として略円形状に形成され、延在方向Xで略同径に形成される。 As shown in FIGS. 1 to 4, the electric wire W includes a conductive linear conductor portion W1 and an insulating covering portion W2 that covers the outside of the conductor portion W1. The electric wire W is an insulated electric wire in which a conductor portion W1 is covered with a covering portion W2. The conductor portion W1 is configured as a core wire obtained by bundling a plurality of element wires of conductive metal such as copper, copper alloy, aluminum, aluminum alloy, etc., or a twisted core wire obtained by twisting a plurality of element wires. The covering portion W2 is a wire covering that covers the outer peripheral side of the conductor portion W1. The covering portion W2 is formed by extruding an insulating resin material such as PP (polypropylene), PVC (polyvinyl chloride), cross-linked PE (polyethylene), or the like. The insulating resin material forming the coating W2 is appropriately selected in consideration of abrasion resistance, chemical resistance, heat resistance, and the like. At the tip of the electric wire W, the covering portion W2 is stripped and the tip of the conductor portion W1 is exposed from the tip of the covering portion W2. The electric wire 100 with a terminal has a terminal 1 connected to the tip of the electric wire W from which the conductor portion W1 is exposed. As shown in FIG. 1, the electric wire W of the embodiment has a conductor portion W1 having a substantially circular shape and a covering portion W2 having a substantially annular shape in a cross-sectional shape in a direction intersecting with the linear extending direction X. , and formed to have substantially the same diameter in the extending direction X. As shown in FIG.

端子1は、主に、基部2と、溶接固定部3と、固定片4と、当接部5と、を含み構成される。端子1は、基部2と、溶接固定部3と、固定片4と、当接部5と、を含む全体が導電性の金属である、銅や、銅合金、アルミニウム、アルミニウム合金等で一体に形成され、その表面にすずメッキ等が施された端子金具である。端子1は、導電性の金属が各構成部に対応した形状に打ち抜かれた一枚の板金を、プレス加工、及び、折り曲げ加工によって成形して立体的に一体で形成される。 The terminal 1 mainly includes a base portion 2 , a weld fixing portion 3 , a fixing piece 4 and a contact portion 5 . The terminal 1 is integrally made of a conductive metal such as copper, copper alloy, aluminum, aluminum alloy, etc., including the base portion 2, the welded fixing portion 3, the fixing piece 4, and the contact portion 5. It is a terminal fitting that is formed and whose surface is plated with tin or the like. The terminal 1 is three-dimensionally integrally formed by pressing and bending a piece of sheet metal in which a conductive metal is punched into a shape corresponding to each constituent part.

基部2は、電線Wの延在方向Xに沿って形成され、導体部W1と被覆部W2とに当接する部分である。基部2は、接続部2Aと、溶接部2Bと、支持部2Cと、固定部2Dと、を含む。基部2は、接続部2Aと、溶接部2Bと、支持部2Cと、固定部2Dと、がこの順で延在方向Xに沿って連続し、延在方向X、及び、幅方向Yにおいて板面を展開する板形状に形成される。ここで、延在方向Xにおいて接続部2Aに向く側を正面側とし、固定部2Dに向く側を背面側とする。 The base portion 2 is formed along the extending direction X of the electric wire W and is a portion that contacts the conductor portion W1 and the coating portion W2. The base 2 includes a connecting portion 2A, a welding portion 2B, a supporting portion 2C, and a fixing portion 2D. The base portion 2 includes a connecting portion 2A, a welding portion 2B, a supporting portion 2C, and a fixing portion 2D, which are continuous in this order along the extending direction X, and extend in the extending direction X and the width direction Y. It is formed in the shape of a plate with an expanded surface. Here, the side facing the connecting portion 2A in the extending direction X is the front side, and the side facing the fixing portion 2D is the rear side.

接続部2Aは、導電性部材と電気的に接続される部分である。導電性部材は、例えば、アース部材(不図示)である。実施形態の接続部2Aは、板厚を貫通する貫通孔2Aaが形成され、この貫通孔2Aaにボルト等が挿通されてアース部材に対して電気的に接続される。なお、導電性部材は、相手側端子(不図示)であってもよい。この場合、接続部2Aは、相手側端子に対して電気的に接続される雄型、または、雌型の端子接続部として構成される。 The connecting portion 2A is a portion electrically connected to the conductive member. The conductive member is, for example, a ground member (not shown). The connection portion 2A of the embodiment is formed with a through hole 2Aa penetrating through the plate thickness, and a bolt or the like is inserted through the through hole 2Aa to be electrically connected to the ground member. The conductive member may be a mating terminal (not shown). In this case, the connection portion 2A is configured as a male-type or female-type terminal connection portion that is electrically connected to the mating terminal.

溶接部2Bは、接続部2Aの延在方向Xの背面側に連続して形成される。溶接部2Bは、幅方向Yの両側に溶接固定部3が形成される。溶接固定部3は、溶接部2Bから折り曲げ加工によって各図で示す上下方向Zの上側に立ち上がって形成される板片として構成される。溶接固定部3は、抵抗溶接やレーザ溶接等の熱によって溶融する部分であり、溶融後に固化することで電線Wの先端に露出した導体部W1と溶接部2Bとを固定する。従って、幅方向Yの両側に溶接固定部3が形成された溶接部2Bは、各溶接固定部3の間で電線Wの導体部W1を配置する幅寸法を有する。また、溶接部2Bは、溶融固化した溶接固定部3によって固定された電線Wの導体部W1が各図で示す上下方向Zの上側の板面に接触して配置される。 The welded portion 2B is formed continuously on the back side in the extending direction X of the connecting portion 2A. The welded portion 2B has welded fixing portions 3 formed on both sides thereof in the width direction Y. As shown in FIG. The welded fixing portion 3 is configured as a plate piece formed by bending from the welded portion 2B so as to rise upward in the up-down direction Z shown in each drawing. The weld fixing portion 3 is a portion that is melted by heat such as resistance welding or laser welding, and solidifies after melting to fix the conductor portion W1 exposed at the tip of the electric wire W and the weld portion 2B. Therefore, the welded portion 2B formed with the welded fixing portions 3 on both sides in the width direction Y has a width dimension for arranging the conductor portion W1 of the electric wire W between the welded fixing portions 3 . The welded portion 2B is arranged such that the conductor portion W1 of the electric wire W fixed by the melted and solidified welded fixing portion 3 is in contact with the upper plate surface in the vertical direction Z shown in each drawing.

支持部2Cは、溶接部2Bの延在方向Xの背面側に連続して形成される。支持部2Cは、溶接部2Bから背面側に向かって幅方向Yの幅寸法が大きくなるように広がって形成されている。支持部2Cは、溶接部2Bに向く正面側で幅方向Yの小さい幅寸法が溶接部2Bと同等であり、電線Wの導体部W1を配置する幅寸法を有する。また、支持部2Cは、背面側で幅方向Yの大きい幅寸法が電線Wの被覆部W2を配置する幅寸法を有する。さらに、支持部2Cは、溶接部2Bから背面側に向かって上下方向Zの下側に向けて傾斜して形成されている。従って、支持部2Cは、電線Wの被覆部W2から導体部W1が露出して外径が変化する部分において、導体部W1と被覆部W2とが各図で示す上下方向Zの上側の板面に沿って配置される。 The support portion 2C is formed continuously on the back side in the extending direction X of the welded portion 2B. 2 C of support parts are formed so that the width dimension of the width direction Y may become large toward a back side from the welding part 2B, and is formed. The supporting portion 2C has a small width dimension in the width direction Y on the front side facing the welding portion 2B, which is the same as that of the welding portion 2B, and has a width dimension in which the conductor portion W1 of the electric wire W is arranged. In addition, the support portion 2C has a width dimension in which the covering portion W2 of the electric wire W is disposed on the rear surface side in the width direction Y, which is larger. Further, the support portion 2C is formed so as to be inclined downward in the up-down direction Z from the welded portion 2B toward the back side. Therefore, in the support portion 2C, in a portion where the conductor portion W1 is exposed from the covering portion W2 of the electric wire W and the outer diameter changes, the conductor portion W1 and the covering portion W2 are located on the upper plate surface in the up-down direction Z shown in each drawing. placed along the

また、支持部2Cは、幅方向Yの両側に支持片6が形成される。支持片6は、支持部2Cから折り曲げ加工によって各図で示す上下方向Zの上側に立ち上がって形成される板片として構成される。実施形態の支持片6は、溶接固定部3と延在方向Xにおいて連続して形成されているが、連続していなくてもよい。また、支持片6は、溶接固定部3よりも上下方向Zの高さ寸法が小さく形成されている。各支持片6は、支持部2Cの延在方向Xに沿って形成され、背面側に向かって幅方向Yの間隔が大きくなるように形成されている。従って、各支持片6は、その間に、電線Wの被覆部W2から導体部W1が露出して外径が変化する部分を挟んで支持できる。 Support pieces 6 are formed on both sides in the width direction Y of the support portion 2C. The support piece 6 is configured as a plate piece formed by bending from the support portion 2C so as to rise upward in the up-down direction Z shown in each drawing. Although the support piece 6 of the embodiment is formed continuously with the welded fixing portion 3 in the extension direction X, it does not have to be continuous. Further, the support piece 6 is formed so that the height dimension in the vertical direction Z is smaller than that of the weld fixing portion 3 . Each supporting piece 6 is formed along the extending direction X of the supporting portion 2C, and is formed such that the interval in the width direction Y increases toward the rear side. Therefore, each supporting piece 6 can be supported by sandwiching therebetween the portion where the conductor portion W1 is exposed from the covering portion W2 of the electric wire W and the outer diameter changes.

固定部2Dは、支持部2Cの延在方向Xの背面側に連続して形成される。固定部2Dは、支持部2Cにおいて幅方向Yの幅寸法が大きくなった部分と幅寸法が同等である。固定部2Dは、接続部2A、及び、溶接部2Bと延在方向Xで平行に配置されている。従って、固定部2Dは、電線Wの被覆部W2が各図で示す上下方向Zの上側の板面に沿って配置される。また、固定部2Dは、幅方向Yの両側に固定片4が形成される。固定片4は、固定部2Dから折り曲げ加工によって各図で示す上下方向Zの上側の立ち上がり方向に立ち上がって形成される板片として構成される。各固定片4は、上下方向Zの高さ寸法が電線Wの被覆部W2の直径の半分を超えて形成される。各固定片4は、固定部2Dの延在方向Xに沿って形成されている。従って、各固定片4は、それぞれが電線Wの被覆部W2の周面の一部に対向して配置され、相互の間に被覆部W2を挟んで支持できる。 The fixed portion 2D is formed continuously on the back side in the extending direction X of the support portion 2C. The fixed portion 2D has the same width as the portion of the supporting portion 2C whose width in the width direction Y is increased. The fixing portion 2D is arranged parallel to the connecting portion 2A and the welding portion 2B in the extending direction X. As shown in FIG. Accordingly, the fixed portion 2D is arranged along the upper plate surface in the up-down direction Z shown in each drawing where the covering portion W2 of the electric wire W is located. In addition, the fixing pieces 4 are formed on both sides in the width direction Y of the fixing portion 2D. The fixed piece 4 is configured as a plate piece that is formed by bending from the fixed portion 2</b>D so as to rise upward in the up-down direction Z shown in each drawing. Each fixed piece 4 is formed such that the height dimension in the vertical direction Z exceeds half the diameter of the covering portion W2 of the electric wire W. As shown in FIG. Each fixed piece 4 is formed along the extending direction X of the fixed portion 2D. Therefore, each fixed piece 4 is arranged to face a part of the peripheral surface of the covering portion W2 of the electric wire W, and can support the covering portion W2 therebetween.

当接部5は、固定片4に形成される。当接部5は、図1から図4に示す実施形態において、固定片4の正面側の縁に形成された切欠として構成されている。当接部5は、矩形状の切欠により構成され、固定片4の正面側の縁を正面側に開放するコ字形状に形成する。当接部5は、延在方向Xにおいて、背面側が塞がって正面側に向く第一端面5Aを形成する。また、当接部5は、上下方向Zにおいて、上側が塞がって下側に向く第二端面5Bを形成する。また、当接部5は、上下方向Zにおいて、第二端面5Bと対向し、下側が塞がって上側に向く第三端面5Cを形成する。当接部5は、電線Wの配置からすると、第一端面5Aが電線Wの先端側に向き、第二端面5Bが電線Wの基部2に対する接触側に向き、第三端面5Cが電線Wの基部2に対する離隔側に向く。 The contact portion 5 is formed on the fixed piece 4 . In the embodiment shown in FIGS. 1 to 4, the contact portion 5 is configured as a notch formed in the edge of the fixed piece 4 on the front side. The abutting portion 5 is formed by a rectangular notch, and is formed in a U-shape opening the edge of the fixing piece 4 on the front side to the front side. The contact portion 5 forms a first end face 5</b>A facing the front side in the extending direction X with the rear side closed. In addition, the contact portion 5 forms a second end surface 5B that is closed at the upper side and faces downward in the vertical direction Z. As shown in FIG. In addition, the contact portion 5 forms a third end surface 5C that faces the second end surface 5B in the up-down direction Z, is closed at the bottom, and faces upward. Considering the arrangement of the electric wire W, the contact portion 5 has a first end surface 5A facing the tip side of the electric wire W, a second end surface 5B facing the contact side of the electric wire W with respect to the base portion 2, and a third end surface 5C facing the electric wire W. It faces away from the base 2 .

上述した端子付電線100を製造する製造方法は、図1から図5に示すように、電線Wを基部2の上側の板面に載置し、抵抗溶接やレーザ溶接等の熱によって溶接固定部3と導体部W1とを溶接で固定する(ステップS1)。このとき、ステップS1の溶接の熱によって被覆部W2の一部が溶融した溶融部W2aを当接部5の中に入り込ませて幅方向Yの外側に出す(ステップS2)。次に、溶融部W2aを固化した溶融固化部W2a’を形成する(ステップS3)。 1 to 5, the manufacturing method for manufacturing the terminal-equipped electric wire 100 described above is to place the electric wire W on the upper plate surface of the base portion 2, and weld and fix the portion by heat such as resistance welding or laser welding. 3 and the conductor W1 are fixed by welding (step S1). At this time, the melted portion W2a, which is a portion of the covering portion W2 melted by the heat of the welding in step S1, is made to enter the contact portion 5 and emerge outside in the width direction Y (step S2). Next, a molten solidified portion W2a' is formed by solidifying the molten portion W2a (step S3).

ステップS2において、被覆部W2は、ステップS1で溶接固定部3に加わる熱が溶接部2Bから支持部2Cを経て固定部2Dに伝わり、図4に示すように固定部2Dの板面に沿う部分が溶融して変形する。そして、被覆部W2は、固定片4に挟まれることで溶融部W2aが当接部5の中に入り込み、当接部5から幅方向Yの外側にはみ出す。また、ステップS3において、溶融部W2aは、溶融固化部W2a’として固化し、当接部5の第一端面5A、第二端面5B、及び、第三端面5Cに突き当たる。 In step S2, the heat applied to the welded fixing portion 3 in step S1 is transferred from the welded portion 2B to the fixed portion 2D via the support portion 2C, and as shown in FIG. melts and deforms. As the covering portion W2 is sandwiched between the fixed pieces 4, the fusion portion W2a enters the contact portion 5 and protrudes outward in the width direction Y from the contact portion 5. As shown in FIG. Further, in step S3, the melted portion W2a is solidified as a melted and solidified portion W2a', and hits the first end surface 5A, the second end surface 5B, and the third end surface 5C of the contact portion 5.

このような製造方法により形成された端子付電線100は、当接部5の第一端面5Aに溶融固化部W2a’が当接することで、延在方向Xに沿って電線Wの後端側への溶融固化部W2a’の移動を規制する。また、端子付電線100は、当接部5の第二端面5Bに溶融固化部W2a’が当接することで、上下方向Zの上側である固定片4の立ち上がり方向に沿って基部2から離れる側への溶融固化部W2a’の移動を規制する。 The terminal-attached electric wire 100 formed by such a manufacturing method moves toward the rear end side of the electric wire W along the extending direction X by contacting the first end surface 5A of the contact portion 5 with the melted and solidified portion W2a′. restricts the movement of the molten solidified portion W2a'. Further, the terminal-equipped electric wire 100 is separated from the base portion 2 along the rising direction of the fixed piece 4, which is the upper side in the vertical direction Z, by contacting the second end surface 5B of the contact portion 5 with the melted and solidified portion W2a'. to regulate the movement of the molten solidified portion W2a'.

ここで、例えば、端子を電線に取り付けて端子付電線を製造する際、かしめ加工を行う工程と、溶着を行う工程と、を要する場合、製造工数が多く、製造時間が嵩み、製造コストが高くなる傾向がある。また一方で、端子付電線は、電線Wと端子との脱落を抑制するため、電線Wが延在方向Xの後端側に移動する応力と、電線Wが基部2から離れる側に移動する応力に耐える強度を有することが要求される。 Here, for example, when manufacturing an electric wire with a terminal by attaching a terminal to an electric wire, if a step of crimping and a step of welding are required, the number of manufacturing steps is large, the manufacturing time is long, and the manufacturing cost is high. tend to be higher. On the other hand, since the terminal-equipped electric wire suppresses the falling off of the electric wire W and the terminal, the stress that the electric wire W moves to the rear end side in the extending direction X and the stress that the electric wire W moves to the side away from the base portion 2 are applied. It is required to have the strength to withstand

これに対し、実施形態の端子付電線100、及び、端子付電線100の製造方法は、導体部W1を固定する溶接の熱によって被覆部W2が溶融した溶融部W2aを当接部5に入り込ませ、この溶融部W2aを固化した溶融固化部W2a’を形成している。このため、実施形態の端子付電線100、及び、端子付電線100の製造方法によれば、例えば、かしめ加工、及び、溶着の工程を要することがなく、溶接するだけでよく製造を容易に行うことができ、端子1と電線Wとを適正に固定できる。 On the other hand, in the electric wire 100 with terminal and the method for manufacturing the electric wire 100 with terminal according to the embodiment, the melted portion W2a in which the covering portion W2 is melted by the welding heat for fixing the conductor portion W1 is made to enter the contact portion 5. , forming a melted and solidified portion W2a′ obtained by solidifying the melted portion W2a. Therefore, according to the electric wire 100 with a terminal and the method for manufacturing the electric wire 100 with a terminal of the embodiment, for example, the steps of caulking and welding are not required, and the manufacturing can be easily performed only by welding. , and the terminal 1 and the wire W can be properly fixed.

また、実施形態の端子付電線100では、当接部5は、被覆部W2において溶融して固化した溶融固化部W2a’が当接し、延在方向Xに沿って電線Wの後端側への溶融固化部W2a’の移動、及び、固定片4の立ち上がり方向である上下方向Zに沿って基部2から離れる側への溶融固化部W2a’の移動を規制する。このため、実施形態の端子付電線100によれば、電線Wが基部2から離れる側に移動する応力に耐える強度を有することができ、端子1と電線Wとを適正に固定できる。 Further, in the electric wire 100 with terminal of the embodiment, the contact portion 5 is in contact with the melted and solidified portion W2a′ melted and solidified in the covering portion W2, and extends toward the rear end side of the electric wire W along the extending direction X. Movement of the melted and solidified portion W2a′ and movement of the melted and solidified portion W2a′ away from the base portion 2 along the vertical direction Z, which is the rising direction of the fixed piece 4, are restricted. Therefore, according to the terminal-equipped wire 100 of the embodiment, the wire W can have the strength to withstand the stress that moves away from the base 2, and the terminal 1 and the wire W can be properly fixed.

具体的に、実施形態の端子付電線100は、当接部5の第一端面5Aが、延在方向Xに沿って電線Wの後端側への溶融固化部W2a’の移動を規制し、当接部5の第二端面5Bが、上下方向Zの上側である固定片4の立ち上がり方向に沿って基部2から離れる側への溶融固化部W2a’の移動を規制する。なお、実施形態の端子付電線100は、当接部5の第二端面5Bと第三端面5Cとの間で溶融固化部W2a’を上下方向Zで挟むため、電線Wが基部2に対して上下方向Zに振動することを抑制でき、端子1と電線Wとを適正に固定できる。 Specifically, in the terminal-equipped wire 100 of the embodiment, the first end surface 5A of the contact portion 5 regulates the movement of the melted and solidified portion W2a' toward the rear end side of the wire W along the extending direction X, The second end surface 5B of the contact portion 5 restricts the movement of the molten solidified portion W2a' away from the base portion 2 along the rising direction of the fixing piece 4, which is the upper side in the vertical direction Z. In the electric wire 100 with terminal of the embodiment, since the molten solidified portion W2a′ is sandwiched in the vertical direction Z between the second end surface 5B and the third end surface 5C of the contact portion 5, the electric wire W is Vibration in the vertical direction Z can be suppressed, and the terminal 1 and the wire W can be properly fixed.

この端子付電線101を製造する製造方法は、端子付電線100と同様にステップ1からステップ3の工程を含む(図5参照)。ステップS2において、被覆部W2は、ステップS1で溶接固定部3に加わる熱によって溶融して変形した溶融部W2aが当接部51の中に入り込み、当接部51から幅方向Yの外側にはみ出す。また、ステップS3において、溶融部W2aは、溶融固化部W2a’として固化し、当接部51の第一端面51A、第二端面51B、及び、第三端面51Cに突き当たる。このため、実施形態の端子付電線101、及び、端子付電線101の製造方法によれば、溶接するだけでよく製造を容易に行うことができ、端子11と電線Wとを適正に固定できる。また、実施形態の端子付電線101は、当接部51の第一端面51Aが、延在方向Xに沿って電線Wの後端側への溶融固化部W2a’の移動を規制し、当接部51の第二端面51Bが、上下方向Zの上側である固定片4の立ち上がり方向に沿って基部2から離れる側への溶融固化部W2a’の移動を規制する。このため、実施形態の端子付電線101によれば、電線Wが基部2から離れる側に移動する応力に耐える強度を有することができ、端子11と電線Wとを適正に固定できる。なお、実施形態の端子付電線101は、当接部51の第二端面51Bと第三端面51Cとの間で溶融固化部W2a’を上下方向Zで挟むため、電線Wが基部2に対して上下方向Zに振動することを抑制でき、端子11と電線Wとを適正に固定できる。 The manufacturing method for manufacturing this terminal-equipped electric wire 101 includes steps 1 to 3 as in the case of the terminal-equipped electric wire 100 (see FIG. 5).

In addition, since the electric wire 101 with a terminal of the embodiment sandwiches the molten solidified portion W2a′ in the vertical direction Z between the second end surface 51B and the third end surface 51C of the contact portion 51, the electric wire W is Vibration in the vertical direction Z can be suppressed, and the terminal 11 and the wire W can be properly fixed.

図9に示す変形例の端子付電線100では、固定片4は、電線Wの被覆部W2に向けて幅方向Yに弾性力を付与されている。具体的に、各固定片4は、図9に一点鎖線で示すように電線Wを取り付ける前は幅方向Yの内側に寄せて傾斜して形成されている。そして、各固定片4の間に電線Wの被覆部W2を配置することで、各固定片4が被覆部W2により幅方向Yの外側に押し広げられる。これにより、各固定片4は、被覆部W2に向けて幅方向Yに弾性力を付与される。 In the terminal-equipped electric wire 100 of the modified example shown in FIG. Specifically, each fixing piece 4 is formed so as to be inclined toward the inside in the width direction Y before the electric wire W is attached, as indicated by the dashed line in FIG. 9 . By arranging the covering portion W2 of the wire W between the fixing pieces 4, the fixing pieces 4 are spread outward in the width direction Y by the covering portion W2. As a result, each fixed piece 4 is given an elastic force in the width direction Y toward the covering portion W2.

図9に示す変形例の端子付電線100は、固定片4が被覆部W2に向けて弾性力を付与されているため、その製造のステップS2(図5参照)において、固定片4の弾性力によって溶融部W2aが当接部53の中に押し込まれて入り込みやすくなる。この結果、実施形態の端子付電線100、及び、端子付電線100の製造方法によれば、製造が容易であり、かつ、溶融固化部W2a’を確実に各端面5A,5B,5Cに当接させて、端子1と電線Wとを適正に固定できる。なお、上記の構造は、端子付電線101,102,103に適用することも可能である。 In the modified terminal-attached electric wire 100 shown in FIG. 9, since the fixing piece 4 is given an elastic force toward the covering portion W2, the elastic force of the fixing piece 4 is , the fusion zone W2a is easily pushed into the contact part 53. As shown in FIG. As a result, according to the electric wire 100 with a terminal and the method for manufacturing the electric wire 100 with a terminal of the embodiment, the manufacturing is easy, and the melted and solidified portion W2a′ is reliably brought into contact with the end faces 5A, 5B, 5C. and the terminal 1 and the electric wire W can be properly fixed. The above structure can also be applied to the electric wires 101, 102, 103 with terminals.

図10は、実施形態に係る端子付電線の変形例の側断面図である。 FIG. 10 is a side cross-sectional view of a modification of the terminal-equipped electric wire according to the embodiment.

図10に示す変形例の端子付電線100では、基部2の固定部2Dに、上下方向Zに貫通する孔7が形成されている。孔7は、円形状やその他の形状に形成される。 In the modified electric wire 100 with terminal shown in FIG. 10 , a hole 7 penetrating in the up-down direction Z is formed in the fixed portion 2D of the base 2 . The holes 7 are formed in circular or other shapes.

図10に示す変形例の端子付電線100は、その製造のステップS2(図5参照)において、導体部W1の溶接時に溶接固定部3に加わる熱によって被覆部W2が溶融して変形し、その溶融部W2bが孔7の中に入り込み、孔7から上下方向Zの下側にはみ出す。さらに、ステップ2の追加工程として、孔7から上下方向Zの下側にはみ出した溶融部W2bを延在方向X、及び幅方向Yを含む面方向に広げて変形させる。この追加工程は、固定部2Dの上下方向Zの下側から孔7を囲む凹型を用いることで実施できる。この追加工程により、固定部2Dの上下方向Zの下側で孔7の周縁に掛かる溶融部W2baが形成される。その後、ステップS3において、溶融部W2a,W2b,W2baを固化した溶融固化部W2a’,W2b’,W2ba’を形成する。 In the modified electric wire with terminal 100 shown in FIG. 10, in the manufacturing step S2 (see FIG. 5), the covering portion W2 is melted and deformed by the heat applied to the weld fixing portion 3 when the conductor portion W1 is welded. The fusion zone W2b enters the hole 7 and protrudes downward in the vertical direction Z from the hole 7. - 特許庁Furthermore, as an additional process of step 2, the melted portion W2b protruding downward in the vertical direction Z from the hole 7 is expanded and deformed in the planar direction including the extending direction X and the width direction Y. As shown in FIG. This additional step can be performed by using a concave mold surrounding the hole 7 from below the fixed part 2D in the vertical direction Z. As shown in FIG. Through this additional step, a fusion zone W2ba that hangs over the periphery of the hole 7 is formed on the lower side of the fixed part 2D in the vertical direction Z. As shown in FIG. Thereafter, in step S3, melted and solidified portions W2a', W2b' and W2ba' are formed by solidifying the melted portions W2a, W2b and W2ba.

図10に示す変形例の端子付電線100は、孔7が、延在方向Xに沿って電線Wの後端側への溶融固化部W2ab’の移動を規制する。また、図10に示す実施形態の端子付電線100は、孔7の周縁が、上下方向Zの上側である固定片4の立ち上がり方向に沿って基部2から離れる側への溶融固化部W2ba’の移動を規制する。このため、実施形態の端子付電線100によれば、電線Wが基部2から離れる側に移動する応力に耐える強度を有することができ、端子1と電線Wとを適正に固定できる。なお、実施形態の端子付電線100は、孔7の内周面で溶融固化部W2b’を囲むため、電線Wが基部2に対して延在方向Xに振動することを抑制でき、端子1と電線Wとを適正に固定できる。また、図10に示す実施形態の端子付電線100、及び、端子付電線100の製造方法によれば、溶接するだけでよく製造を容易に行うことができ、端子1と電線Wとを適正に固定できる。なお、上記の構成は、端子付電線101,102,103に適用することも可能である。 10, the hole 7 restricts the movement of the molten solidified portion W2ab' toward the rear end side of the electric wire W along the extending direction X. As shown in FIG. In the electric wire 100 with a terminal of the embodiment shown in FIG. Regulate movement. Therefore, according to the terminal-equipped wire 100 of the embodiment, the wire W can have the strength to withstand the stress that moves away from the base 2, and the terminal 1 and the wire W can be properly fixed. In the electric wire 100 with terminal of the embodiment, since the inner peripheral surface of the hole 7 surrounds the melted and solidified portion W2b′, the electric wire W can be suppressed from vibrating in the extending direction X with respect to the base portion 2. The electric wire W can be properly fixed. Moreover, according to the electric wire 100 with a terminal and the method for manufacturing the electric wire 100 with a terminal of the embodiment shown in FIG. can be fixed. The above configuration can also be applied to the electric wires 101, 102, 103 with terminals.
