Description

本発明は例えば自動車等に用いられる端子付き電線およびその製造方法に関するものである。   The present invention relates to a terminal-equipped electric wire used for, for example, an automobile, and a method for manufacturing the same.

従来、自動車、OA機器、家電製品等の分野では、電力線や信号線として、電気導電性に優れた銅系材料からなる電線が使用されている。特に、自動車分野においては、車両の高性能化、高機能化が急速に進められており、車載される各種電気機器や制御機器が増加している。したがって、これに伴い、使用される端子付き電線も増加する傾向にある。   2. Description of the Related Art Conventionally, in the fields of automobiles, office automation equipment, home electric appliances, and the like, electric wires made of a copper-based material having excellent electric conductivity have been used as power lines and signal lines. In particular, in the field of automobiles, high performance and high functionality of vehicles are being rapidly promoted, and various electric devices and control devices mounted on vehicles are increasing. Accordingly, the number of electric wires with terminals used tends to increase accordingly.

一方、環境問題が注目される中、自動車の軽量化が要求されている。したがって、ワイヤハーネスの使用量増加に伴う重量増加が問題となる。このため、従来使用されている銅線に代えて、軽量なアルミニウム電線が注目されている。   On the other hand, with the focus on environmental issues, there is a demand for lighter vehicles. Therefore, there is a problem of an increase in weight due to an increase in the use amount of the wire harness. For this reason, attention has been paid to lightweight aluminum electric wires in place of conventionally used copper wires.

ここで、このような電線同士を接続する際や機器類等の接続部においては、接続用端子が用いられる。しかし、アルミニウム電線を用いた端子付き電線であっても、接続部の信頼性等のため、端子部には、電気特性に優れる銅が使用される場合がある。このような場合には、アルミニウム電線と銅製の端子とが接合されて使用される。   Here, a connection terminal is used at the time of connecting such electric wires or at a connection portion of devices or the like. However, even in the case of an electric wire with a terminal using an aluminum electric wire, copper having excellent electric characteristics may be used for the terminal portion in some cases due to the reliability of the connection portion. In such a case, an aluminum electric wire and a copper terminal are used by being joined.

しかし、異種金属を接触させると、標準電極電位の違いから、いわゆる電食が発生する恐れがある。特に、アルミニウムと銅との標準電極電位差は大きいため、接触部への水の飛散や結露等の影響により、電気的に卑であるアルミニウム側の腐食が進行する。このため、接続部における電線と端子との接続状態が不安定となり、接触抵抗の増加や線径の減少による電気抵抗の増大、更には断線が生じて電装部品の誤動作、機能停止に至る恐れがある。   However, when different metals are brought into contact with each other, so-called electrolytic corrosion may occur due to a difference in the standard electrode potential. In particular, since the standard electrode potential difference between aluminum and copper is large, corrosion of the electrically-noble aluminum side progresses due to the effects of water scattering and dew condensation on the contact portion. For this reason, the connection state between the electric wire and the terminal in the connection portion becomes unstable, and the electric resistance increases due to an increase in the contact resistance and a decrease in the wire diameter. is there.

このため、電線と端子との接続部を防食材で被覆する方法が提案されている。しかし、圧着後の端子付き電線に防食材を塗布すると、防食材が流れてしまい、必要な部分を確実に防食材で覆うことができない場合がある。   For this reason, a method has been proposed in which the connection between the electric wire and the terminal is covered with an anticorrosive material. However, when the anticorrosive material is applied to the crimped electric wire with terminal, the anticorrosive material flows, and a necessary portion may not be reliably covered with the anticorrosive material.

これに対し、端子圧着部と端子本体との間のトランジション部に流れ止めを形成して、導線圧着部を被覆する樹脂が端子本体側に流れることを抑制する端子付き電線の製造方法が提案されている。(特許文献1)。   On the other hand, there has been proposed a method for manufacturing a terminal-equipped wire in which a flow stopper is formed at a transition portion between a terminal crimping portion and a terminal main body to suppress a resin covering the conductor crimping portion from flowing toward the terminal main body. ing. (Patent Document 1).

しかし、圧着時に、導線圧着部の先端から露出する導線が変形し、導線の先端部が他の部位よりも上方に向けて突き出すおそれがある。この場合には、導線の一部が樹脂被覆部から上方に露出する場合がある。また、被覆圧着部と導線圧着部との間において、導線が上方に膨らみ、この部位において、導線の一部が樹脂被覆部から露出する場合がある。このように、導線の一部が樹脂被覆部から露出すると、十分な防食性を確保できなくなる。   However, at the time of crimping, the conductor exposed from the tip of the conductor crimping part may be deformed, and the tip of the conductor may protrude upward from other parts. In this case, a part of the conductive wire may be exposed upward from the resin coating. In addition, the conductive wire may swell upward between the coated crimping portion and the conductive wire crimping portion, and at this portion, a portion of the conductive wire may be exposed from the resin coating portion. As described above, when a part of the conductive wire is exposed from the resin-coated portion, it is not possible to secure sufficient corrosion protection.

本発明は、このような問題に鑑みてなされたもので、樹脂被覆からの導線の露出を抑制して、確実に防食性を確保することが可能な端子付き電線およびその製造方法を提供することを目的とする。   The present invention has been made in view of such a problem, and it is an object of the present invention to provide a terminal-equipped electric wire capable of suppressing exposure of a conductive wire from a resin coating and reliably ensuring corrosion protection, and a method of manufacturing the same.

That is, the covered conductor 11 includes the covered portion 15 and the conductor 13 exposed from the tip. The conducting wire 13 is, for example, a stranded wire in which a plurality of strands are twisted.

端子1は、オープンバレル型であり、銅または銅合金製である。端子1には被覆導線11が接続される。端子1は、端子本体3と圧着部5とがトランジション部4を介して連結されて構成される。圧着部5と端子本体3の間に位置するトランジション部4は、上方が開口する。   The terminal 1 is an open barrel type and is made of copper or a copper alloy. The terminal 1 is connected to a covered conductor 11. The terminal 1 is configured by connecting a terminal body 3 and a crimping portion 5 via a transition portion 4. The upper part of the transition part 4 located between the crimping part 5 and the terminal body 3 is open.

端子本体3は、所定の形状の板状素材を、断面が矩形の筒体に形成したものである。端子本体3は、内部に、板状素材を矩形の筒体内に折り込んで形成される弾性接触片を有する。端子本体3は、前端部から雄型端子などが挿入されて接続される。なお、以下の説明では、端子本体3が、雄型端子等の挿入タブ(図示省略)の挿入を許容する雌型端子である例を示すが、本発明において、この端子本体3の細部の形状は特に限定されない。例えば、雌型の端子本体3に代えて例えば雄型端子の挿入タブを設けてもよい。   The terminal body 3 is formed by forming a plate-shaped material having a predetermined shape into a tubular body having a rectangular cross section. The terminal body 3 has an elastic contact piece formed by folding a plate-shaped material into a rectangular cylinder inside.

The conductive wire 13 from which the covering portion 15 is peeled off and exposed is crimped by the conductor crimping portion 7. In the wire crimping portion 7, the wire 13 and the terminal 1 are electrically connected. In addition, the end face of the covering portion 15 is located in the inter-barrel portion 8 between the covering crimping portion 9 and the wire crimping portion 7.

トランジション部4には、樹脂製の流出防止部19が設けられる。流出防止部19の高さは、導線13の先端部の高さ(トランジション部4上面からの高さ)よりも高い。例えば、図2に示すように、導線13の先端は、導線圧着部7における導線13の高さよりも高くなる場合があるが、流出防止部19の高さは、導線圧着部7から露出する導線13の先端部の高さよりも高い。特に、図示したように、導線圧着部7の先端に露出する導線13の先端の高さが、導線圧着部7の先端部における上面高さよりも高くなる場合には、流出防止部19は、導線13の先端部の高さよりも高い位置まで形成されるため、導線圧着部7の先端部における上面高さよりも高くまで形成されることとなる。なお、流出防止部19は、トランジション部4の幅方向の全幅に渡って形成される。   The transition section 4 is provided with a resin outflow prevention section 19. The height of the outflow prevention portion 19 is higher than the height of the distal end portion of the conductive wire 13 (height from the upper surface of the transition portion 4). For example, as shown in FIG. 2, the leading end of the conductive wire 13 may be higher than the height of the conductive wire 13 in the conductive wire crimping portion 7, but the height of the outflow prevention portion 19 may be larger than the height of the conductive wire exposed from the conductive wire crimping portion 7. 13 is higher than the height of the tip. In particular, as shown in the figure, when the height of the distal end of the conductive wire 13 exposed at the distal end of the conductive wire crimping portion 7 is higher than the upper surface height at the distal end portion of the conductive wire crimping portion 7, the outflow preventing portion 19 is connected to the conductive wire. 13 is formed to a position higher than the height of the distal end portion of the conductive wire crimping portion 7, so that the conductive wire crimping portion 7 is formed to be higher than the top surface height. The outflow prevention portion 19 is formed over the entire width of the transition portion 4 in the width direction.

本実施形態では、少なくとも、バレル間部8から流出防止部19までの導線13が露出する部位が防食材17で覆われている。また、防食材17は、流出防止部19の上端近傍まで設けられるため、導線13が、防食材17によって完全に覆われて、外部に露出しない。   In the present embodiment, at least a portion where the conductive wire 13 is exposed from the inter-barrel portion 8 to the outflow prevention portion 19 is covered with the anticorrosion material 17. In addition, since the anticorrosion material 17 is provided to the vicinity of the upper end of the outflow prevention portion 19, the conductive wire 13 is completely covered by the anticorrosion material 17 and is not exposed to the outside.

なお、防食材17および流出防止部19を構成する樹脂は、例えば、アクリレート系の光硬化樹脂である。なお、防食材17と流出防止部19とは、明確な境界なく完全に一体化されていてもよい。この場合でも、両者の形成タイミングが異なるため、その境界を、断面研磨後に光学顕微鏡や偏光顕微鏡で識別は可能である。   The resin constituting the anticorrosion material 17 and the outflow prevention portion 19 is, for example, an acrylate-based photocurable resin. In addition, the anticorrosion material 17 and the outflow prevention part 19 may be completely integrated without a clear boundary. Even in this case, since the two are formed at different timings, the boundary can be identified by an optical microscope or a polarizing microscope after polishing the cross section.

次に、端子付き電線10の製造方法について説明する。まず、被覆導線11と端子1とを圧着により接続する。次に、トランジション部4に、樹脂の塗布と硬化によって、流出防止部19を形成する。ここで、流出防止部19は、ジェットディスペンサによって、樹脂を打ち出す工程と、樹脂を硬化させる工程を繰り返し、樹脂を、所定の幅に対し所定の高さに積層させることで形成することができる。   Next, a method of manufacturing the electric wire with terminal 10 will be described. First, the covered conductor 11 and the terminal 1 are connected by crimping. Next, the outflow prevention section 19 is formed on the transition section 4 by applying and curing a resin. Here, the outflow prevention unit 19 can be formed by repeating the step of ejecting the resin and the step of curing the resin by the jet dispenser, and stacking the resin at a predetermined height with respect to a predetermined width.

例えば、図3(a)に示すように、トランジション部4に対して樹脂の液滴をジェットディスペンサで打ち出し、打ち出しと連動させて光を照射させて硬化させ、その横に、同様にしてわずかにラップするように樹脂の液滴の打ち出しと硬化を行い、トランジション部4の幅方向に流出防止部19を形成する。すなわち、流出防止部19は、複数の樹脂の液滴の塗布と硬化を繰り返して形成されることが望ましい。なお、光を点滅させて打ち出しと連動させるのではなく、光を照射した状態で樹脂を打ち出してもよい。トランジション部4の全幅に渡って流出防止部19が形成されると、次に、1段目の流出防止部19の上部に、2段目の流出防止部19を積層する。   For example, as shown in FIG. 3A, a droplet of resin is ejected to the transition section 4 with a jet dispenser, and light is radiated in conjunction with the ejection to cure the resin. The resin droplets are ejected and hardened so as to wrap, and the outflow prevention portions 19 are formed in the width direction of the transition portion 4. That is, it is desirable that the outflow prevention unit 19 is formed by repeatedly applying and curing a plurality of resin droplets. Note that the resin may be ejected in a state of irradiating the light, instead of blinking the light and linking it with the ejection. When the outflow prevention portions 19 are formed over the entire width of the transition portion 4, the second-stage outflow prevention portions 19 are stacked on the first-stage outflow prevention portions 19 next.

図3(b)に示すように、上記の工程を繰り返すことで、トランジション部4において、樹脂が積層されている流出防止部19を形成することができ、導線圧着部7から露出する導線13の先端部の高さよりも高く流出防止部19を形成することができる。なお、前述したように、流出防止部19を構成する硬化した樹脂の各液滴や各層の樹脂は、形成タイミングが異なるため、その境界を、断面研磨後に光学顕微鏡や偏光顕微鏡で識別は可能である。   As shown in FIG. 3B, by repeating the above steps, the outflow prevention portion 19 in which the resin is laminated can be formed in the transition portion 4, and the lead 13 exposed from the lead crimping portion 7 can be formed. The outflow prevention portion 19 can be formed higher than the height of the distal end portion. As described above, since the formation timing of each droplet of the cured resin and the resin of each layer constituting the outflow prevention portion 19 is different, the boundary thereof can be identified by an optical microscope or a polarizing microscope after section polishing. is there.

図4は、流出防止部19近傍の拡大図である。前述したように、樹脂の液滴の打ち出しと硬化とを繰り返すことで、厚みに対して高さの高い流出防止部19を形成することができる。ここで、流出防止部19の高さ(トランジション部4の鏡面からの高さ)をHとすると、前述したように、高さHは、導線13の先端部の高さ(図中C)よりも高い。   FIG. 4 is an enlarged view of the vicinity of the outflow prevention unit 19. As described above, by repeatedly ejecting and curing the resin droplets, it is possible to form the outflow prevention portion 19 having a height higher than the thickness. Here, assuming that the height of the outflow prevention portion 19 (the height of the transition portion 4 from the mirror surface) is H, the height H is greater than the height of the distal end portion of the conductive wire 13 (C in the figure) as described above. Is also expensive.

また、平面視において、流出防止部19の頂点(平面視における厚みの中心)から流出防止部19の裾野までの距離(すなわち、流出防止部19の厚み(電線の長手方向の厚み)の1/2)をDとする。この場合、距離Dは、3mm以下であることが望ましい。   Further, in plan view, the distance from the vertex of the outflow prevention portion 19 (the center of the thickness in plan view) to the foot of the outflow prevention portion 19 (that is, 1 / th of the thickness of the outflow prevention portion 19 (the thickness in the longitudinal direction of the electric wire)). Let 2) be D. In this case, the distance D is desirably 3 mm or less.

ここで、距離Dは、端子のサイズ等によって適切な値が変わる。一般に、大型端子ではDが大きくなり、小型端子ではDは小さくなる。Dが大きすぎると、硬化前の流出防止部19の樹脂材の滴が、端子の複数の部位に同時に接触することで、滴の形状がくずれるため、流出防止部19を所望の形状に形成することが困難である。一方、Dが小さすぎると、流出防止部19を形成するために樹脂材の滴の数が多くなるため、製造に要する時間が長くなる。すなわちコストアップ要因となる。   Here, an appropriate value of the distance D changes depending on the size of the terminal and the like. In general, D is large for large terminals and D is small for small terminals. If D is too large, the droplet of the resin material of the outflow prevention portion 19 before curing simultaneously contacts a plurality of portions of the terminal, and the shape of the droplet is distorted, so that the outflow prevention portion 19 is formed in a desired shape. It is difficult. On the other hand, if D is too small, the number of droplets of the resin material increases to form the outflow prevention portion 19, so that the time required for manufacturing becomes long. That is, it becomes a factor of cost increase.

また、流出防止部19のH/Dは、0.5以上であることが望ましく、さらに望ましくは1.0以上であり、2以上であればより望ましい。このように、Dに対するHを所定以上大きくすることで、流出防止部19が、厚みに対して十分な高さを有するため、より効率の良い流出防止部19となる。   Further, the H / D of the outflow prevention portion 19 is preferably 0.5 or more, more preferably 1.0 or more, and more preferably 2 or more. As described above, by making H with respect to D larger than a predetermined value, the outflow preventing portion 19 has a sufficient height with respect to the thickness, so that the outflow preventing portion 19 becomes more efficient.

次に、流出防止部19の後方(少なくともバレル間部8から流出防止部19までの間)に防食材17を塗布した後、光照射することで防食材17を硬化させ、バレル間部8から流出防止部19までの導線13が露出する部位を防食材17で覆う。以上により、端子付き電線10を得ることができる。   Next, after the anticorrosion material 17 is applied to the rear of the outflow prevention portion 19 (at least between the inter-barrel portion 8 and the outflow prevention portion 19), the anticorrosion material 17 is cured by light irradiation, A portion where the conductive wire 13 is exposed to the outflow prevention portion 19 is covered with the anticorrosion material 17. Thus, the electric wire with terminal 10 can be obtained.

なお、本発明において、防食材17を塗布するとは、防食材17の液滴を対象部に接触させる方法や、防食材17の液滴を供給部から打ち出して(滴下させて)対象部に付着させる方法など、対象部に防食材17が付着した状態を得る方法の全てを含むものとする。例えば、防食材17の液滴を対象部に対して、メカニカルディスペンサで接触させて塗布してもよく、流出防止部19と同様に、ジェットディスペンサで供給部から打ち出して塗布してもよい。   In the present invention, the application of the anticorrosion material 17 means that the droplets of the anticorrosion material 17 are brought into contact with the target portion, or the droplets of the anticorrosion material 17 are ejected from the supply section (dropped) and adhere to the target portion. The method includes all methods for obtaining a state in which the anticorrosion material 17 is attached to the target portion, such as a method for causing the anticorrosion material 17 to adhere to the target portion. For example, a droplet of the anticorrosion material 17 may be applied to the target portion by contacting it with a mechanical dispenser, or, similarly to the outflow prevention portion 19, may be ejected from a supply portion by a jet dispenser and applied.

なお、流出防止部19を形成する樹脂の粘度は、例えば常温で1000mPa・s以上の樹脂を加熱して100mPa・sで打ち出すことで、ジェットディスペンサによる打ち出しが可能であるとともに、打ち出し後の樹脂が流れてしまうことを抑制することができる。一方、防食材17の粘度は、1000mPa・s以下で塗布すればよく、より好ましくは、粘度を数mPa・s〜数百mPa・s程度とすればよく、例えば、浸透性をより高めるため、3mPa・s以下の粘度でも良い。   In addition, the viscosity of the resin forming the outflow prevention portion 19 is, for example, by heating a resin of 1000 mPa · s or more at room temperature and firing the resin at 100 mPa · s. Flowing can be suppressed. On the other hand, the viscosity of the anticorrosion material 17 may be applied at 1000 mPa · s or less, and more preferably, the viscosity may be about several mPa · s to several hundred mPa · s. The viscosity may be 3 mPa · s or less.

以上説明したように、本実施形態によれば、トランジション部4に、導線13の高さよりも高い流出防止部19が形成されるため、流出防止部19を堰として、防食材17を流出防止部19の高さまで塗布することができる。このため、導線圧着部7の先端(端子本体3側の端部)から露出する導線13を確実に防食材17で覆うことができる。特に、導線圧着部7において強圧着する場合には、導線圧着部7の先端から露出する導線13の先端が、導線圧着部7の上面よりも高い位置に跳ね上がる場合があるが、流出防止部19を、さらにそれ以上の高さに形成することで、確実に防食性を確保することができる。また、この場合には、流出防止部19の高さが、導線圧着部7の上面よりも高い位置まで形成されるため、導線圧着部7の上面に塗布した防食材17の流出を防止することができる。   As described above, according to the present embodiment, since the outflow prevention portion 19 that is higher than the height of the conductive wire 13 is formed in the transition portion 4, the anticorrosion material 17 is formed by using the outflow prevention portion 19 as a weir. It can be applied up to a height of 19. For this reason, the conductive wire 13 exposed from the front end (the end on the terminal body 3 side) of the conductive wire crimping portion 7 can be reliably covered with the anticorrosive material 17. In particular, when the wire crimping portion 7 is strongly crimped, the tip of the conductor 13 exposed from the tip of the wire crimping portion 7 may jump to a position higher than the upper surface of the wire crimping portion 7. Is formed at a height higher than that, the anticorrosion can be surely secured. Also, in this case, the height of the outflow prevention portion 19 is formed to a position higher than the upper surface of the conductor crimping portion 7, so that the anticorrosion material 17 applied to the upper surface of the conductor crimping portion 7 is prevented from flowing out. Can be.

また、樹脂を積層して流出防止部19が形成されるため、厚みに対して高さの高い流出防止部19を得ることができる。このため、効率よく、所定高さの流出防止部19を得ることができ、防食材17の流出を防止しつつ所定の高さまで防食材17を塗布することができる。   Further, since the outflow prevention portion 19 is formed by laminating the resin, the outflow prevention portion 19 having a height higher than the thickness can be obtained. Therefore, the outflow prevention portion 19 having a predetermined height can be efficiently obtained, and the anticorrosion material 17 can be applied to the predetermined height while preventing the anticorrosion material 17 from flowing out.

また、流出防止部19と防食材17がいずれも光硬化樹脂であるため、短時間で硬化させることができ、製造性が良好である。   Further, since both the outflow prevention portion 19 and the anticorrosion material 17 are photocurable resins, they can be cured in a short time, and the manufacturability is good.

次に、第2の実施形態について説明する。図5(a)は、端子付き電線10aを示す平面図である。なお、以下の説明において、第1の実施形態と同様の機能を奏する構成については、図1〜図4と同一の符号を付し、重複する説明を省略する。また、以下に示す各流出防止部は、前述の通り、複数の樹脂の液滴が硬化することで形成される。   Next, a second embodiment will be described. FIG. 5A is a plan view showing the electric wire with terminal 10a. In the following description, components having the same functions as those in the first embodiment are denoted by the same reference numerals as those in FIGS. 1 to 4, and redundant description will be omitted. As described above, the outflow prevention portions described below are formed by curing a plurality of resin droplets.

端子付き電線10aは、端子付き電線10と略同様の構成であるが、流出防止部19に加えて流出防止部19aが設けられる点で異なる。前述したように、トランジション部4の上方には、トランジション部4の全幅に渡って、流出防止部19が設けられる。すなわち、流出防止部19は、トランジション部4の側壁部の内面に接触する。   The electric wire with terminal 10a has substantially the same configuration as the electric wire with terminal 10, but differs in that an outflow prevention portion 19a is provided in addition to the outflow prevention portion 19. As described above, the outflow prevention portion 19 is provided over the entire width of the transition portion 4 above the transition portion 4. That is, the outflow prevention portion 19 contacts the inner surface of the side wall portion of the transition portion 4.

流出防止部19aは、トランジション部4の側壁上に形成される。すなわち、流出防止部19aの厚みは、トランジション部4の側壁の厚み以下で形成される。例えば、流出防止部19aのD(図4参照)は、0.1mm程度である。流出防止部19aは、流出防止部19と略同一の高さであって、流出防止部19から導線圧着部7側に向けて形成される。すなわち、流出防止部19、19aで導線圧着部7の先端側を略コの字状に囲むように形成される。   The outflow prevention portion 19a is formed on the side wall of the transition portion 4. That is, the thickness of the outflow prevention portion 19a is formed to be equal to or less than the thickness of the side wall of the transition portion 4. For example, D (see FIG. 4) of the outflow prevention portion 19a is about 0.1 mm. The outflow prevention portion 19a has substantially the same height as the outflow prevention portion 19, and is formed from the outflow prevention portion 19 toward the conductor crimping portion 7 side. That is, the outflow prevention portions 19 and 19a are formed so as to surround the leading end side of the wire crimping portion 7 in a substantially U-shape.

防食材17は、バレル間部8から、流出防止部19、19aで囲まれる範囲にわたって設けられ、バレル間部8から導線圧着部7の先端露出する導線13を覆う。   The anticorrosion material 17 is provided over the area between the barrel portion 8 and the area surrounded by the outflow prevention portions 19 and 19a, and covers the conductive wire 13 exposed from the barrel portion 8 at the tip of the wire crimping portion 7.

第2の実施形態によれば、第1の実施形態と同様の効果を得ることができる。また、トランジション部4の側壁上に流出防止部19aを設けることで、トランジション部4の側壁よりも高い流出防止部19、19aとすることができる。このため、トランジション部4の側方への防食材17の流出を防止することができ、より確実に、導線13を防食材17で覆うことができる。   According to the second embodiment, the same effect as in the first embodiment can be obtained. Further, by providing the outflow prevention portions 19a on the side walls of the transition portion 4, the outflow prevention portions 19, 19a that are higher than the side walls of the transition portion 4 can be provided. For this reason, it is possible to prevent the anticorrosion material 17 from flowing out to the side of the transition portion 4, and it is possible to more reliably cover the conductive wire 13 with the anticorrosion material 17.

次に、第3の実施形態について説明する。図5(b)は、第3の実施形態にかかる端子付き電線10bを示す平面図である。端子付き電線10bは、端子付き電線10aと略同様の構成であるが、流出防止部19、19aに加えて流出防止部19bが設けられる点で異なる。   Next, a third embodiment will be described. FIG. 5B is a plan view illustrating the electric wire with terminal 10b according to the third embodiment. The electric wire with terminal 10b has substantially the same configuration as the electric wire with terminal 10a, but differs in that an outflow prevention portion 19b is provided in addition to the outflow prevention portions 19 and 19a.

前述したように、トランジション部4の上方には、トランジション部4の全幅に渡って、流出防止部19が設けられる。また、流出防止部19aは、トランジション部4の側壁上に形成される。流出防止部19bは、流出防止部19、19aと略同一の高さであって、導線圧着部7の先端部近傍に、両サイドの流出防止部19a同士を繋ぐように設けられる。すなわち、流出防止部19、19a、19bで導線圧着部7の先端側を略ロの字状に囲むように形成される。   As described above, the outflow prevention portion 19 is provided over the entire width of the transition portion 4 above the transition portion 4. The outflow prevention portion 19a is formed on the side wall of the transition portion 4. The outflow prevention portions 19b have substantially the same height as the outflow prevention portions 19 and 19a, and are provided near the distal end of the wire crimping portion 7 so as to connect the outflow prevention portions 19a on both sides. That is, the outflow prevention portions 19, 19a, and 19b are formed so as to surround the distal end side of the wire crimping portion 7 in a substantially rectangular shape.

防食材17は、流出防止部19、19a、19bで囲まれた範囲内と、バレル間部8から、流出防止部19bまでに設けられ、導線13を覆う。なお、この場合でも、バレル間部8から流出防止部19までの導線13が露出する部位が防食材17で覆われているとする。   The anticorrosion material 17 is provided in a range surrounded by the outflow prevention portions 19, 19 a, and 19 b, and between the barrel portion 8 and the outflow prevention portion 19 b, and covers the conductive wire 13. Also in this case, it is assumed that the portion where the conductive wire 13 is exposed from the inter-barrel portion 8 to the outflow prevention portion 19 is covered with the anticorrosion material 17.

第3の実施形態によれば、第2の実施形態と同様の効果を得ることができる。また、導線圧着部7の先端側に流出防止部19bを設けることで、導線圧着部7の先端側の導線13を確実に防食材17で覆うことができる。   According to the third embodiment, the same effects as in the second embodiment can be obtained. In addition, by providing the outflow preventing portion 19 b on the distal end side of the conductive wire crimping portion 7, the conductive wire 13 on the distal end side of the conductive wire crimping portion 7 can be reliably covered with the anticorrosion material 17.

次に、第4の実施形態について説明する。図6(a)は、第4の実施形態にかかる端子付き電線10cを示す平面図である。端子付き電線10cは、端子付き電線10aと略同様の構成であるが、流出防止部19、19aに加えて流出防止部19cが設けられる点で異なる。   Next, a fourth embodiment will be described. FIG. 6A is a plan view showing an electric wire with terminal 10c according to the fourth embodiment. The electric wire with terminal 10c has substantially the same configuration as the electric wire with terminal 10a, but differs in that an outflow prevention portion 19c is provided in addition to the outflow prevention portions 19 and 19a.

流出防止部19cは、被覆圧着部9の先端部(導線圧着部7側の端部)近傍に幅方向に形成されるとともに、バレル間部8の両側壁上にバレル間部8を挟むように形成される。すなわち、流出防止部19cでバレル間部8を後方から略コの字状に囲むように形成される。   The outflow prevention portion 19c is formed in the width direction near the tip end (the end on the conductor wire crimping portion 7 side) of the covering crimping portion 9 and sandwiches the inter-barrel portion 8 on both side walls of the inter-barrel portion 8. It is formed. That is, the outflow preventing portion 19c is formed so as to surround the inter-barrel portion 8 in a substantially U-shape from the rear.

防食材17は、流出防止部19、19aで囲まれた範囲から流出防止部19cで囲まれた範囲まで設けられ、当該範囲における導線13を覆う。   The anticorrosion material 17 is provided from a range surrounded by the outflow prevention portions 19 and 19a to a range surrounded by the outflow prevention portion 19c, and covers the conductive wire 13 in the range.

第4の実施形態によれば、第2の実施形態と同様の効果を得ることができる。また、防食材17が、被覆圧着部9の後方や側方に流出することも抑制することができる。   According to the fourth embodiment, the same effects as those of the second embodiment can be obtained. In addition, it is possible to suppress the anticorrosion material 17 from flowing out behind or to the side of the coating and crimping portion 9.

次に、第5の実施形態について説明する。図6(b)は、第5の実施形態にかかる端子付き電線10dを示す平面図である。端子付き電線10dは、端子付き電線10cと略同様の構成であるが、流出防止部19、19a、19cに加えて流出防止部19dが設けられる点で異なる。   Next, a fifth embodiment will be described. FIG. 6B is a plan view showing an electric wire with terminal 10d according to the fifth embodiment. The electric wire with terminal 10d has substantially the same configuration as the electric wire with terminal 10c, but differs in that an outflow prevention portion 19d is provided in addition to the outflow prevention portions 19, 19a, and 19c.

前述したように、流出防止部19、19aによって、導線圧着部7の先端側が略コの字状に囲まれる。また、流出防止部19cによって、バレル間部8が後方から略コの字状に囲まれる。流出防止部19dは、流出防止部19aと流出防止部19cを繋ぐように設けられる。すなわち、流出防止部19dは、導線圧着部7の上方であって、バレル同士の突合せ部の両側に設けられ、流出防止部19、19a、19c、19dによってバレル間部8からトランジション部4までの所定の範囲が囲まれる。   As described above, the leading end side of the wire crimping portion 7 is surrounded by the outflow preventing portions 19 and 19a in a substantially U-shape. Also, the outflow preventing portion 19c surrounds the barrel-to-barrel portion 8 in a substantially U-shape from the rear. The outflow prevention unit 19d is provided so as to connect the outflow prevention unit 19a and the outflow prevention unit 19c. That is, the outflow prevention portions 19d are provided above the wire crimping portion 7 and on both sides of the butting portion of the barrels, and are provided by the outflow prevention portions 19, 19a, 19c, and 19d from the inter-barrel portion 8 to the transition portion 4. A predetermined range is enclosed.

防食材17は、流出防止部19、19a、19c、19dで囲まれた範囲に設けられ、当該範囲における導線13を覆う。   The anticorrosion material 17 is provided in a range surrounded by the outflow prevention portions 19, 19a, 19c, and 19d, and covers the conductive wire 13 in the range.

第5の実施形態によれば、第4の実施形態と同様の効果を得ることができる。また、バレル同士の突合せ部の両側の流出防止部19dの間を防食材17で覆うことができ、導線圧着部7の側方に防食材17が流出することも抑制することができる。   According to the fifth embodiment, the same effects as in the fourth embodiment can be obtained. Further, the space between the outflow prevention portions 19d on both sides of the butted portion of the barrels can be covered with the anticorrosion material 17, and the outflow of the anticorrosion material 17 to the side of the wire crimping portion 7 can also be suppressed.

次に、第6の実施形態について説明する。図7(a)は、第6の実施形態にかかる端子付き電線10eを示す平面図であり、図7(b)は、端子付き電線10eを示す断面図である。端子付き電線10eは、端子付き電線10と略同様の構成であるが、流出防止部19に加えて流出防止部19eが設けられる点で異なる。   Next, a sixth embodiment will be described. FIG. 7A is a plan view illustrating an electric wire with terminal 10e according to the sixth embodiment, and FIG. 7B is a cross-sectional view illustrating the electric wire with terminal 10e. The electric wire with terminal 10e has substantially the same configuration as the electric wire with terminal 10 except that an outflow prevention portion 19e is provided in addition to the outflow prevention portion 19.

流出防止部19eは、導線圧着部7の上方または後方(バレル間部8との境界部近傍)に、導線圧着部7またはバレル間部8の全幅に設けられる。図7(c)は、流出防止部19e近傍の拡大図である。流出防止部19eの高さ(図中H1)は、被覆部15から露出する導線の高さ(図中C1)よりも高い。なお、高さH1及びC1は、いずれもバレル間部8における端子上面からの高さである。   The outflow prevention portion 19e is provided over or behind the wire crimping portion 7 (near the boundary with the inter-barrel portion 8) over the entire width of the wire crimping portion 7 or the inter-barrel portion 8. FIG. 7C is an enlarged view near the outflow prevention portion 19e. The height (H1 in the drawing) of the outflow prevention portion 19e is higher than the height (C1 in the drawing) of the conductor exposed from the covering portion 15. Both the heights H1 and C1 are the heights of the inter-barrel portions 8 from the upper surface of the terminal.

防食材17は、流出防止部19eの後方と、流出防止部19の後方のそれぞれに設けられる。すなわち、バレル間部8から流出防止部19eまでの導線13が露出する部位が、防食材17で覆われるとともに、流出防止部19eから流出防止部19までの導線13が露出する部位が、防食材17で覆われる。   The anticorrosion material 17 is provided behind the outflow prevention portion 19e and behind the outflow prevention portion 19, respectively. That is, the portion where the conductive wire 13 from the barrel space 8 to the outflow prevention portion 19e is exposed is covered with the anticorrosion material 17, and the portion where the conductive wire 13 from the outflow prevention portion 19e to the outflow prevention portion 19 is exposed is the anticorrosion material. 17 covered.

なお、前述したように、トランジション部4には、導線13の先端部の高さよりも高い流出防止部19が設けられ、導線圧着部7の上方または後方には、被覆部15から露出する導線13の高さよりも高い流出防止部19eが設けられる。この際、トランジション部4に設けられる流出防止部19と、導線圧着部7の上方または後方に設けられる流出防止部19eの高さは異なり、流出防止部19eの高さの方が高い。   As described above, the transition portion 4 is provided with the outflow prevention portion 19 that is higher than the height of the end portion of the conductor 13, and above or behind the wire crimping portion 7, the conductor 13 exposed from the covering portion 15 is provided. An outflow prevention portion 19e higher than the height is provided. At this time, the height of the outflow prevention portion 19e provided in the transition portion 4 and the height of the outflow prevention portion 19e provided above or behind the wire crimping portion 7 are different, and the height of the outflow prevention portion 19e is higher.

第6の実施形態によれば、第1の実施形態と同様の効果を得ることができる。また、導線圧着部7の先端部の導線13を確実に覆うとともに、バレル間部8における導線13を確実に覆うことができる。また、各部の導線13の高さに応じた高さで防食材17を塗布することができるため、流出防止部19のみで防食材17の塗布高さを設定する場合と比較して、防食材17の塗布量を削減することができる。なお、バレル間部8における導線13を防食材17で確実に覆う場合には、流出防止部19は必ずしも必要ではなく、流出防止部19eのみとしてもよい。   According to the sixth embodiment, the same effects as those of the first embodiment can be obtained. In addition, the conductor 13 at the distal end of the conductor crimping portion 7 can be reliably covered, and the conductor 13 in the inter-barrel section 8 can be reliably covered. Further, since the anticorrosion material 17 can be applied at a height corresponding to the height of the conductive wire 13 of each part, the anticorrosion material can be applied as compared with the case where the application height of the anticorrosion material 17 is set only by the outflow prevention portion 19. 17 can be reduced. When the conductor 13 in the inter-barrel section 8 is surely covered with the anticorrosion material 17, the outflow prevention section 19 is not always necessary, and only the outflow prevention section 19e may be provided.

次に、第7の実施形態について説明する。図8(a)は、第7の実施形態にかかる端子付き電線10fを示す平面図である。端子付き電線10fは、端子付き電線10cと略同様の構成であるが、流出防止部19、19aに代えて、流出防止部19eが設けられる点で異なる。   Next, a seventh embodiment will be described. FIG. 8A is a plan view illustrating an electric wire with terminal 10f according to the seventh embodiment. The electric wire with terminal 10f has substantially the same configuration as the electric wire with terminal 10c, but differs in that an outflow prevention portion 19e is provided instead of the outflow prevention portions 19 and 19a.

本実施形態では、流出防止部19が形成されない。このように、導線圧着部7の先端部おける導線13については、防食材17で容易に被覆することができれば、流出防止部19を設けなくてもよい。一方、前述したように、バレル間部8においては、被覆部15から露出する導線13の高さが高い。このため、バレル間部8における導線13をより確実に覆うため、流出防止部19c、19eによって、バレル間部8を囲む。このようにすることで、バレル間部8の周囲に防食材17が流出することをより確実に抑制し、導線13を防食材17で覆うことができる。   In the present embodiment, the outflow prevention portion 19 is not formed. As described above, the lead wire 13 at the distal end of the lead wire crimping portion 7 does not need to be provided with the outflow prevention portion 19 as long as it can be easily covered with the anticorrosion material 17. On the other hand, as described above, in the inter-barrel section 8, the height of the conductive wire 13 exposed from the covering section 15 is high. For this reason, in order to more reliably cover the conducting wire 13 in the inter-barrel section 8, the outflow-prevention sections 19c and 19e surround the inter-barrel section 8. In this way, it is possible to more reliably suppress the anticorrosion material 17 from flowing around the inter-barrel section 8 and cover the conductive wire 13 with the anticorrosion material 17.

第7の実施形態によれば、バレル間部8における導線13を確実に覆うことができる。   According to the seventh embodiment, it is possible to reliably cover the conducting wire 13 in the inter-barrel portion 8.

次に、第8の実施形態について説明する。図8(b)は、第8の実施形態にかかる端子付き電線10gを示す平面図である。端子付き電線10gは、端子付き電線10fと略同様の構成であるが、流出防止部19、19a、19bと、流出防止部19c、19eが設けられる点で異なる。   Next, an eighth embodiment will be described. FIG. 8B is a plan view showing an electric wire with terminal 10g according to the eighth embodiment. The electric wire with terminal 10g has substantially the same configuration as the electric wire with terminal 10f, but differs in that outflow prevention portions 19, 19a and 19b and outflow prevention portions 19c and 19e are provided.

前述したように、トランジション部4において、流出防止部19、19a、19bで導線圧着部7の先端側が、略ロの字状に囲まれる。また、バレル間部8が、流出防止部19c、19eで囲まれる。   As described above, in the transition portion 4, the leading end side of the wire crimping portion 7 is surrounded by the outflow preventing portions 19, 19a, and 19b in a substantially square shape. In addition, the inter-barrel section 8 is surrounded by the outflow prevention sections 19c and 19e.

防食材17は、流出防止部19、19a、19b及び流出防止部19c、19eで囲まれた範囲と、導線圧着部7の上方に塗布される。すなわち、バレル間部8から、トランジション部4までの間の、導線13が防食材17で覆われる。   The anticorrosion material 17 is applied to the area surrounded by the outflow prevention portions 19, 19a, 19b and the outflow prevention portions 19c, 19e and above the conductive wire crimping portion 7. In other words, the conductive wire 13 between the barrel portion 8 and the transition portion 4 is covered with the anticorrosion material 17.

第8の実施形態によれば、第3の実施形態及び第7の実施形態と同様の効果を得ることができる。このように、特に導線13の露出のおそれがある部位を流出防止部で囲むことで、防食材17の流出を効率よく抑制し、導線13をより確実に防食材17で覆うことができる。   According to the eighth embodiment, the same effects as those of the third embodiment and the seventh embodiment can be obtained. In this way, by particularly circumventing the portion where the conductive wire 13 is likely to be exposed by the outflow preventing portion, the outflow of the anticorrosive material 17 can be efficiently suppressed, and the conductive wire 13 can be more reliably covered with the anticorrosive material 17.

次に、第9の実施形態について説明する。図9(a)は、第9の実施形態にかかる端子付き電線10hを示す平面図である。端子付き電線10hは、端子付き電線10dと略同様の構成であるが、流出防止部19eが設けられる点で異なる。   Next, a ninth embodiment will be described. FIG. 9A is a plan view showing an electric wire with terminal 10h according to the ninth embodiment. The electric wire with terminal 10h has substantially the same configuration as the electric wire with terminal 10d, but differs in that an outflow prevention portion 19e is provided.

本実施形態では、流出防止部19c、19eでバレル間部8が囲まれ、流出防止部19、19a、19d、19eによって、導線圧着部7からトランジション部4までが囲まれ、それぞれの領域において、防食材17が塗布される。このため、流出防止部19c、19eによって、バレル間部8の周囲へ防食材17が流出することが抑制され、流出防止部19、19a、19d、19eによって、導線圧着部7およびトランジション部4の周囲へ防食材17が流出することが抑制される。   In the present embodiment, the inter-barrel portion 8 is surrounded by the outflow preventing portions 19c and 19e, and the portion from the wire crimping portion 7 to the transition portion 4 is surrounded by the outflow preventing portions 19, 19a, 19d and 19e. An anticorrosion material 17 is applied. For this reason, the anticorrosion material 17 is prevented from flowing out around the inter-barrel portion 8 by the outflow prevention portions 19c and 19e, and the outflow prevention portions 19, 19a, 19d, and 19e prevent the anticorrosion material 17 from forming the conductor crimping portion 7 and the transition portion 4. The outflow of the anticorrosion material 17 to the surroundings is suppressed.

第9の実施形態によれば、第5の実施形態及び第6の実施形態と同様の効果を得ることができる。このように、特に導線13の露出のおそれがある部位を流出防止部で囲むことで、防食材17の流出を効率よく抑制し、導線13をより確実に防食材17で覆うことができるとともに、各部の導線13の高さに応じた高さで防食材17を塗布することができる。   According to the ninth embodiment, the same effects as in the fifth embodiment and the sixth embodiment can be obtained. In this way, especially by enclosing the part where the conductor 13 may be exposed with the outflow prevention part, the outflow of the anticorrosion material 17 can be efficiently suppressed, and the conductor 13 can be more reliably covered with the anticorrosion material 17. The anticorrosion material 17 can be applied at a height corresponding to the height of the conductive wire 13 at each part.

次に、第10の実施形態について説明する。図9(b)は、第10の実施形態にかかる端子付き電線10iを示す平面図である。端子付き電線10iは、端子付き電線10hと略同様の構成であるが、流出防止部19bが設けられる点で異なる。   Next, a tenth embodiment will be described. FIG. 9B is a plan view showing a terminal-attached electric wire 10i according to the tenth embodiment. The terminal-equipped electric wire 10i has substantially the same configuration as the terminal-equipped electric wire 10h, except that an outflow prevention portion 19b is provided.

本実施形態では、流出防止部19c、19eでバレル間部8が囲まれ、流出防止部19、19a、19bによって、導線圧着部7の先端側が囲まれ、流出防止部19b、19d、19eによって、導線圧着部7の上方のバレル同士の突合せ部が囲まれ、それぞれの領域において、防食材17が塗布される。このため、流出防止部19c、19eによって、バレル間部8の周囲へ防食材17が流出することが抑制され、流出防止部19、19a、19bによって、トランジション部4の周囲へ防食材17が流出することが抑制され、流出防止部19b、19d、19eによって、導線圧着部7の周囲へ防食材17が流出することが抑制される。   In the present embodiment, the barrel gap 8 is surrounded by the outflow prevention portions 19c and 19e, and the leading end side of the wire crimping portion 7 is surrounded by the outflow prevention portions 19, 19a and 19b. The butted portion of the barrels above the wire crimping portion 7 is surrounded, and an anticorrosion material 17 is applied in each region. Therefore, the anti-corrosion material 17 is prevented from flowing out around the inter-barrel portion 8 by the outflow prevention portions 19c and 19e, and the anti-corrosion material 17 flows out around the transition portion 4 by the outflow prevention portions 19, 19a and 19b. Is prevented, and the anti-corrosion material 17 is prevented from flowing out around the wire crimping portion 7 by the outflow prevention portions 19b, 19d, and 19e.

第10の実施形態によれば、第9の実施形態と同様の効果を得ることができる。このように、各部を別々に流出防止部で囲むことで、防食材17の流出を効率よく抑制し、導線13をより確実に防食材17で覆うことができるとともに、各部の導線13の高さに応じた高さで防食材17を塗布することができる。   According to the tenth embodiment, the same effects as in the ninth embodiment can be obtained. In this way, by separately surrounding each part with the outflow prevention part, the outflow of the anticorrosion material 17 can be efficiently suppressed, and the conductor 13 can be more reliably covered with the anticorrosion material 17, and the height of the conductor 13 of each part The anticorrosion material 17 can be applied at a height corresponding to the height.

次に、第11の実施形態について説明する。図10は、第11の実施形態にかかる端子付き電線10jを示す断面図である。端子付き電線10jは、端子付き電線10eと略同様の構成であるが、流出防止部19fが設けられる点で異なる。   Next, an eleventh embodiment will be described. FIG. 10 is a sectional view showing an electric wire with terminal 10j according to the eleventh embodiment. The terminal-equipped electric wire 10j has substantially the same configuration as the terminal-equipped electric wire 10e, except that an outflow prevention portion 19f is provided.

本実施形態では、被覆圧着部9の後方の被覆部15の外周に流出防止部19fが設けられる。流出防止部19fは、被覆圧着部9の後方に所定の隙間をあけて形成される。なお、流出防止部19fは、例えば、被覆部15の上方の略半周に渡って形成される。   In the present embodiment, an outflow preventing portion 19f is provided on the outer periphery of the covering portion 15 behind the covering pressure bonding portion 9. The outflow prevention portion 19f is formed behind the covering pressure bonding portion 9 with a predetermined gap. The outflow prevention portion 19f is formed, for example, over substantially a half circumference above the covering portion 15.

流出防止部19fが形成され後、被覆圧着部9と流出防止部19fの間に上方から防食材17を塗布すると、防食材17は、被覆部15の上方から下方に向かって流れ、被覆圧着部9の後端部を全周に渡って覆う。すなわち、被覆圧着部9の後端部から被覆部15の外周の流出防止部19fまでの間を防食材17で覆うことができる。この際、被覆部15の上方に塗布された防食材17は、流出防止部19fによって、被覆導線11に沿って後方に流れることが抑制される。なお、被覆部15の下方の半周においては、防食材17は、被覆圧着部9の後端に沿って流れるため、被覆導線11の後方への流れが抑制され、被覆圧着部9の後端部の全周に渡って防食材17を塗布することができる。   After the outflow prevention portion 19f is formed, when the anticorrosion material 17 is applied from above to between the coating and crimping portion 9 and the outflow prevention portion 19f, the anticorrosion material 17 flows from above the coating portion 15 to below and the coating and crimping portion. 9. Cover the rear end over the entire circumference. That is, the area from the rear end of the coating press-bonding portion 9 to the outflow prevention portion 19f on the outer periphery of the coating portion 15 can be covered with the anticorrosive material 17. At this time, the anticorrosion material 17 applied above the covering portion 15 is prevented from flowing backward along the covered conductor 11 by the outflow preventing portion 19f. In the lower half of the covering portion 15, the anticorrosion material 17 flows along the rear end of the covering crimping portion 9, so that the flow of the covering conductor 11 to the rear is suppressed, and the rear end portion of the covering crimping portion 9 is prevented. The anticorrosion material 17 can be applied over the entire circumference of the above.

第11の実施形態によれば、第6の実施形態と同様の効果を得ることができる。また、被覆圧着部9の後端部を防食材17で覆うことができるため、被覆圧着部9の後端からの水の浸入を抑制することができる。   According to the eleventh embodiment, the same effect as in the sixth embodiment can be obtained. In addition, since the rear end of the coating and crimping section 9 can be covered with the anticorrosive material 17, it is possible to suppress the intrusion of water from the rear end of the coating and crimping section 9.

When the outflow prevention portions are formed at a plurality of locations, it is desirable that the resin and the anticorrosion material 17 constituting all the outflow prevention portions are photocurable resins, but other resins may be used.
