Description
本発明は例えば自動車等に用いられる端子付き電線に関するものである。 TECHNICAL FIELD The present invention relates to an electric wire with a terminal for use in automobiles, for example.
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, OA equipment, home electric appliances, and the like, electric wires made of copper-based materials with excellent electrical conductivity have been used as power lines and signal lines. In particular, in the field of automobiles, the performance and functionality of vehicles are rapidly advancing, and the number of various electric devices and control devices to be mounted on vehicles is increasing. Therefore, along with this, the number of electric wires with terminals used tends to increase.
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, while environmental problems are attracting attention, there is a demand for weight reduction of automobiles. Therefore, an increase in weight due to an increase in the amount of use of the wire harness becomes a problem. For this reason, light weight aluminum wires have attracted attention 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 when connecting such electric wires or at a connection portion of equipment. However, even in an electric wire with a terminal using an aluminum electric wire, there are cases where copper, which has excellent electrical properties, is used for the terminal portion for the reliability of the connecting portion. In such a case, an aluminum electric wire and a copper terminal are joined and used.
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 dissimilar metals are brought into contact with each other, so-called electrolytic corrosion may occur due to the difference in standard electrode potential. In particular, since the standard electrode potential difference between aluminum and copper is large, corrosion on the electrically base aluminum side progresses due to the influence of water splashing and condensation on the contact portion. As a result, the connection between the wire and the terminal at the connection part becomes unstable, and there is a risk of an increase in contact resistance, an increase in electrical resistance due to a decrease in wire diameter, and even a disconnection, which may lead to malfunction or stoppage of electrical components. be.
このため、被覆導線と端子との接続部を樹脂部材で被覆する方法が提案されている（例えば特許文献１）。 For this reason, a method has been proposed in which the connecting portion between the covered conductor and the terminal is covered with a resin member (for example, Patent Document 1).
従来の方法は、端子と被覆導線を圧着した後、接続部の外周に樹脂部材を塗布して、樹脂部材で互いの接触部分を被覆するものである。しかし、被覆導線と端子との微小な隙間に樹脂部材を塗布することは困難である。特に、被覆導線の先端近傍は、被覆部が除去されて内部の導線が露出するが、被覆部の端部と導線露出部の境界部において、外径の変化に伴う微小な隙間が生じやすい。したがって、被覆部と被覆圧着部との隙間を通じて、圧着部内部に水が浸入するおそれがある。 In the conventional method, after crimping the terminal and the covered conductor, a resin member is applied to the outer circumference of the connecting portion to cover the mutual contact portion with the resin member. However, it is difficult to apply the resin member to the minute gap between the coated conductor and the terminal. In particular, in the vicinity of the tip of the covered conductor, the covered part is removed and the conductor inside is exposed. Therefore, there is a possibility that water may enter the inside of the crimping portion through the gap between the covering portion and the covering crimping portion.
本発明は、このような問題に鑑みてなされたもので、圧着部の内部へ水が浸入することを抑制することが可能な端子付き電線を提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide an electric wire with a terminal that can prevent water from entering the inside of the crimping portion.
前述した目的を達成するために本発明は、被覆導線と端子とが接続された端子付き電線であって、前記端子は、前記被覆導線が圧着される圧着部と、端子本体とを有し、前記圧着部は、前記被覆導線の被覆部を圧着する被覆圧着部と、前記被覆部から露出する導線を圧着する導線圧着部とを有し、長手方向の少なくとも一部において、前記被覆圧着部に凹溝が形成されることなく、前記被覆圧着部と前記被覆部との間の全周及び前記被覆部の端部と前記導線の露出部との境界部近傍における前記導線の全周の双方に跨って樹脂部材が塗布されており、前記樹脂部材は、紫外線硬化樹脂であることを特徴とする端子付き電線である。 In order to achieve the above object, the present invention provides an electric wire with a terminal in which a coated conductor and a terminal are connected, wherein the terminal has a crimping portion to which the coated conductor is crimped and a terminal body, The crimping portion has a covering crimping portion for crimping the covering portion of the covered conductor, and a conductor crimping portion for crimping the conductor exposed from the covering portion. Both the entire circumference between the covering crimping portion and the covering portion and the entire circumference of the conducting wire in the vicinity of the boundary portion between the end portion of the covering portion and the exposed portion of the conducting wire without forming a recessed groove. A resin member is applied across the wire, and the resin member is an ultraviolet curable resin.
硬化後の前記樹脂部材の硬度が、前記被覆部の硬度よりも低いことが望ましい。 It is desirable that the hardness of the resin member after curing is lower than the hardness of the covering portion.
本発明によれば、高い防食性を確保することができる。 According to the present invention, high corrosion resistance can be ensured.
また、この際、硬化後の樹脂部材の硬度が被覆部の硬度よりも低ければ、被覆部の圧着時に、樹脂部材が容易に変形して、被覆部と被覆圧着部との隙間を確実に埋めることができる。 Further, at this time, if the hardness of the resin member after curing is lower than the hardness of the covering portion, the resin member is easily deformed when the covering portion is crimped, and the gap between the covering portion and the covering crimping portion is reliably filled. be able to.
本発明によれば、圧着部の内部へ水が浸入することを抑制することが可能な端子付き電線を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the electric wire with a terminal which can suppress that water permeates into the inside of a crimping part can be provided.
以下、図面を参照しながら、本発明の実施形態について説明する。図１は、端子付き電線１０を示す斜視図である。なお、図は、樹脂部材１７を透視した図である。端子付き電線１０は、端子１および被覆導線１１等から構成される。端子１は、オープンバレル型であり、銅もしくは黄銅などの銅合金あるいはそれらにスズなどがめっきされたものが使用される。端子付き電線１０は、端子１と被覆導線１１が接続されて構成される。被覆導線１１は、アルミニウム線またはアルミニウム合金線である導線１３と、導線１３を被覆する被覆部１５からなる。すなわち、被覆導線１１は、被覆部１５と、その先端から露出する導線１３とを具備する。
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an electric wire 10 with a terminal. Note that the drawing is a perspective view of the resin member 17 . An electric wire 10 with a terminal is composed of a
端子１は、端子本体３と圧着部５とからなる。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。
A
圧着部５は、被覆導線１１と圧着される部位であり、圧着前において、端子１の長手方向に垂直な断面形状が略Ｕ字状のバレル形状を有する。端子１の圧着部５は、被覆導線の先端側に被覆部から露出する導線を圧着する導線圧着部７と、被覆導線１１の被覆部１５を圧着する被覆圧着部９とからなる。
The crimping portion 5 is a portion to be crimped with the coated conductor 11, and has a substantially U-shaped cross-sectional shape perpendicular to the longitudinal direction of the
導線圧着部７の内面の一部には、幅方向（長手方向に垂直な方向）には、図示を省略したセレーションが設けられる。このようにセレーションを形成することで、導線を圧着した際に、導線の表面の酸化膜を破壊しやすく、また、導線との接触面積を増加させることができる。 A portion of the inner surface of the conductor crimping portion 7 is provided with serrations (not shown) in the width direction (direction perpendicular to the longitudinal direction). By forming the serrations in this way, when the conductive wire is crimped, the oxide film on the surface of the conductive wire can be easily destroyed, and the contact area with the conductive wire can be increased.
被覆導線１１の先端は、被覆部１５が剥離され、内部の導線１３が露出する。被覆導線１１の被覆部は、端子１の被覆圧着部９によって圧着される。また、被覆部１５が剥離されて露出する導線１３は、導線圧着部７により圧着される。導線圧着部７において導線１３と端子１とが電気的に接続される。なお、被覆部１５の端面は、被覆圧着部９と導線圧着部７の間に位置する。
At the tip of the covered conductor 11, the covering portion 15 is peeled off, and the conductor 13 inside is exposed. The coated portion of the coated conductor 11 is crimped by the coated crimping portion 9 of the
本発明では、少なくとも、被覆部１５や端子１から露出する導線１３が、樹脂部材１７で覆われる。本実施形態では、導線圧着部７および被覆圧着部９が樹脂部材１７によって被覆され、少なくとも導線１３は、樹脂部材１７によって外部に露出しない。すなわち、被覆圧着部９における被覆部１５から導線圧着部７の先端側の導線１３の露出部にわたって樹脂部材１７が塗布されて、樹脂部材１７によって覆われる。樹脂部材１７は、例えば、シリコーンアクリレート、ウレタンアクリレート、アクリルアクリレートなどの紫外線硬化樹脂である。なお、樹脂部材１７の詳細については後述する。
In the present invention, at least the covering portion 15 and the conducting wire 13 exposed from the
次に、端子付き電線１０の製造方法について説明する。図２は、端子１に対して被覆導線１１を配置した状態を示す斜視図であり、図３は、端子付き電線１０（被覆導線１１）の長手方向の断面図である。まず、被覆導線１１の先端の所定長さの被覆部１５を除去して、導線１３を露出させる。次に、圧着部５に被覆導線１１を配置する。この際、導線圧着部７には導線１３の露出部が位置し、被覆圧着部９には被覆部１５が位置する。
Next, a method for manufacturing the electric wire with terminal 10 will be described. FIG. 2 is a perspective view showing a state in which the covered conductor 11 is arranged with respect to the
次に、図４に示すように、導線圧着部７と導線１３を本圧着する（第１圧着工程）。すなわち、この状態においては、導線圧着部７のみが本圧着され、被覆圧着部９は圧着されない。 Next, as shown in FIG. 4, the conductor crimping portion 7 and the conductor 13 are finally crimped (first crimping step). That is, in this state, only the conductor crimping portion 7 is fully crimped, and the cover crimping portion 9 is not crimped.
次に、図５に示すように、被覆圧着部９における被覆部１５から導線圧着部７の先端側の導線１３の露出部にわたって樹脂部材１７を塗布する（樹脂塗布工程）。すなわち、この状態においては、露出する導線１３が完全に樹脂部材１７によって被覆される。 Next, as shown in FIG. 5, the resin member 17 is applied from the covering portion 15 of the covering crimping portion 9 to the exposed portion of the conductor 13 on the tip side of the conductor crimping portion 7 (resin application step). That is, in this state, the exposed conductor 13 is completely covered with the resin member 17 .
なお、導線圧着部７における導線１３の表面の樹脂部材１７の被覆厚は、２０μｍ以上であることが望ましい。樹脂部材１７の被覆厚が十分でないと、防食性が悪くなる。 It is desirable that the thickness of the coating of the resin member 17 on the surface of the conductor 13 in the conductor crimping portion 7 is 20 μm or more. If the coating thickness of the resin member 17 is not sufficient, the anti-corrosion property will be deteriorated.
次に、図６に示すように、被覆圧着部９と、樹脂部材１７が塗布された被覆部１５を本圧着する（第２圧着工程）。すなわち、この状態においては、被覆圧着部９によって、樹脂部材１７とともに被覆部１５が本圧着される。 Next, as shown in FIG. 6, the covering pressure-bonding portion 9 and the covering portion 15 coated with the resin member 17 are fully pressure-bonded (second pressure-bonding step). That is, in this state, the covering portion 15 is fully crimped together with the resin member 17 by the covering pressure bonding portion 9 .
図７（ａ）は、図４のＡ－Ａ線断面図、図７（ｂ）は、図５のＢ－Ｂ線断面図、図７（ｃ）は、図６のＣ－Ｃ線断面図である。また、図８（ａ）は、図４のＤ部拡大図、図８（ｂ）は、図５のＥ部拡大図、図８（ｃ）は、図６のＦ部拡大図である。前述したように、導線圧着部７の本圧着時には、被覆圧着部９は圧着されていない。このため、図７（ａ）に示すように、被覆圧着部９は、上方に向けて開口し、被覆部１５と被覆圧着部９との間には、十分な隙間が生じる。特に、図８（ａ）に示すように、被覆部１５の端部（被覆部１５の端部と導線露出部の境界部周辺における導線１３と端子（圧着部５）との間の隙間）には、十分な隙間が形成され、上部に開口する。 7(a) is a cross-sectional view along the line AA in FIG. 4, FIG. 7(b) is a cross-sectional view along the line BB in FIG. 5, and FIG. 7(c) is a cross-sectional view along the line CC in FIG. is. 8A is an enlarged view of the D section in FIG. 4, FIG. 8B is an enlarged view of the E section in FIG. 5, and FIG. 8C is an enlarged view of the F section in FIG. As described above, when the conductor crimping portion 7 is finally crimped, the covering crimping portion 9 is not crimped. Therefore, as shown in FIG. 7( a ), the covering pressure-bonding portion 9 opens upward, and a sufficient gap is generated between the covering portion 15 and the covering pressure-bonding portion 9 . In particular, as shown in FIG. 8A, at the end of the covering portion 15 (the gap between the conductor 13 and the terminal (crimping portion 5) around the boundary between the end of the covering portion 15 and the conductor exposed portion). is formed with a sufficient gap and opens at the top.
したがって、図７（ｂ）、図８（ｂ）に示すように、被覆圧着部９の上方から樹脂部材１７を容易に塗布することができ、樹脂部材１７を被覆部１５と被覆圧着部９の隙間（特に、被覆部１５の端部と導線露出部の境界部周辺における導線１３と端子（圧着部５）との間の隙間）に浸透させることができる。 Therefore, as shown in FIGS. 7(b) and 8(b), the resin member 17 can be easily applied from above the covering pressure-bonding portion 9, and the resin member 17 can be applied between the covering portion 15 and the covering pressure-bonding portion 9. It can permeate the gap (especially the gap between the conductor 13 and the terminal (crimping part 5) around the boundary between the end of the covering part 15 and the conductor exposed part).
なお、本実施形態では、樹脂部材１７のＪＩＳ Ｚ ８８０３による塗布時（硬化前）の粘度が、１０～２０００ｍＰａ・ｓ（より望ましくは、樹脂部材１７の粘度が、１０～１０００ｍＰａ・ｓ）であることが望ましい。粘度が１０ｍＰａ・ｓ未満では、樹脂部材１７を塗布した際に、樹脂部材１７が圧着部近傍から流れ出し、適切に被覆がされない恐れがある。粘度が１０００ｍＰａ・ｓを超えると、樹脂部材１７を塗布した際に、樹脂部材１７が圧着部の内部まで十分に浸透せず、内部に隙間が生じるおそれがあり、特に粘度が２０００ｍＰａ・ｓを超えると、樹脂部材１７を被覆部１５の下部に浸透させることが困難となる。 In this embodiment, the viscosity of the resin member 17 at the time of application (before curing) according to JIS Z 8803 is 10 to 2000 mPa s (more preferably, the viscosity of the resin member 17 is 10 to 1000 mPa s). is desirable. If the viscosity is less than 10 mPa·s, when the resin member 17 is applied, the resin member 17 may flow out from the vicinity of the crimped portion, resulting in improper coating. If the viscosity exceeds 1000 mPa·s, when the resin member 17 is applied, the resin member 17 may not sufficiently penetrate into the inside of the crimped portion, and a gap may be generated inside. As a result, it becomes difficult to allow the resin member 17 to penetrate into the lower portion of the covering portion 15 .
このように、樹脂部材１７を塗布した状態で、被覆圧着部９を圧着することで、図７（ｃ）、図８（ｃ）に示すように、圧着後には、被覆部１５と被覆圧着部９との隙間が狭くなる部分、特に、被覆部１５の端部と導線露出部の境界部周辺における導線１３と端子（圧着部５）との間の隙間も、確実に樹脂部材１７で埋めることができる。 By crimping the covering pressure-bonding portion 9 in a state where the resin member 17 is applied in this way, as shown in FIGS. 9, especially the gap between the conductor 13 and the terminal (crimping portion 5) around the boundary between the end of the covering portion 15 and the exposed portion of the conductor must be filled with the resin member 17. can be done.
なお、樹脂部材１７は、例えば紫外線硬化樹脂である。この場合、被覆圧着部９の圧着（第２圧着工程）の前に、樹脂部材１７を硬化（樹脂硬化工程）させてもよく、被覆圧着部９の圧着（第２圧着工程）の後に、樹脂部材１７を硬化（樹脂硬化工程）させてもよい。 In addition, the resin member 17 is, for example, an ultraviolet curable resin. In this case, the resin member 17 may be cured (resin curing step) before crimping the covering crimping portion 9 (second crimping step), and after crimping the covering crimping portion 9 (second crimping step), the resin The member 17 may be cured (resin curing step).
被覆圧着部９の圧着の前に、樹脂部材１７を硬化させれば、図７（ｂ）に示すように、被覆圧着部９の上方が開いており、被覆部１５と被覆圧着部９の隙間も大きいため、紫外線をより深くまで照射することができる。また、被覆圧着部９の圧着時に、樹脂部材１７の飛散などが生じにくい。 If the resin member 17 is cured before the covering crimping portion 9 is crimped, the upper portion of the covering crimping portion 9 is open as shown in FIG. is large, it is possible to irradiate ultraviolet rays to a deeper depth. In addition, when the covering pressure-bonding portion 9 is pressure-bonded, the resin member 17 is less likely to scatter.
なお、この場合には、硬化後の樹脂部材１７の硬度が、被覆部１５の硬度よりも低いことが望ましい。例えば、硬化後の樹脂部材１７および被覆部１５の樹脂によって、それぞれ２ｍｍ厚のシートを作成し、ＪＩＳ Ｋ６２５３－３による硬度測定を行った場合、被覆部のデュロメータ硬さはＡ５０～Ａ１００であり、硬化後の樹脂部材１７のデュロメータ硬さはＡ２０～Ａ５０の範囲である。 In this case, it is desirable that the hardness of the resin member 17 after curing is lower than the hardness of the covering portion 15 . For example, when a sheet with a thickness of 2 mm is prepared from each of the cured resin member 17 and the resin of the coating portion 15 and the hardness is measured according to JIS K6253-3, the durometer hardness of the coating portion is A50 to A100. The durometer hardness of the cured resin member 17 is in the range of A20 to A50.
このように、樹脂部材１７の硬度が低いと、被覆部１５を圧着した際に、樹脂部材１７が容易に変形し、被覆部１５と被覆圧着部９との隙間を確実に埋めることができる。 Thus, when the hardness of the resin member 17 is low, the resin member 17 is easily deformed when the covering portion 15 is crimped, and the gap between the covering portion 15 and the covering crimping portion 9 can be reliably filled.
一方、被覆圧着部９の圧着の後に、樹脂部材１７を硬化させれば、被覆圧着部９の圧着時において、樹脂部材１７の流動性を確保することができる。 On the other hand, if the resin member 17 is cured after the covering pressure-bonding portion 9 is pressure-bonded, the fluidity of the resin member 17 can be ensured during the pressure-bonding of the coating pressure-bonding portion 9 .
ここで、前述したように、樹脂部材１７は、例えば紫外線硬化樹脂である。この場合、樹脂部材１７が塗布された端子付き電線１０に上方から紫外線を照射すると、導線１３の影が生じる。すなわち、紫外線が、導線１３の下部の樹脂部材１７へ十分に照射されない恐れがある。しかし、上方から照射された紫外線は、樹脂部材１７を透過し、導線１３の表面や端子１の内面で反射する。このため、導線１３による影部分へも、紫外線が回り込み、樹脂部材１７を硬化させることができる。
Here, as described above, the resin member 17 is, for example, an ultraviolet curable resin. In this case, when the electric wire 10 with terminal coated with the resin member 17 is irradiated with ultraviolet rays from above, a shadow of the conducting wire 13 is generated. That is, the resin member 17 below the conducting wire 13 may not be sufficiently irradiated with ultraviolet rays. However, the ultraviolet rays irradiated from above pass through the resin member 17 and are reflected on the surface of the conducting wire 13 and the inner surface of the
このため、樹脂部材１７は、紫外線が透過しやすい樹脂であれば、より深くまで紫外線を照射することができる。そこで、本発明では、樹脂部材１７の厚さ０．２ｍｍにおける波長３６５ｎｍの分光透過率を６０％以上とすることが望ましい。 For this reason, if the resin member 17 is a resin that easily transmits ultraviolet rays, it is possible to irradiate the ultraviolet rays to a greater depth. Therefore, in the present invention, it is desirable to set the spectral transmittance of the resin member 17 having a thickness of 0.2 mm to 60% or more at a wavelength of 365 nm.
ここで、厚さ０．２ｍｍにおける分光透過率が６０％以上とは、樹脂部材１７を構成する樹脂で０．２ｍｍ厚さのシートを形成し、シートの一方の側から入射した光（例えば光照射量３０００ｍＪ／ｃｍ）が、他方へ透過する透過率である。具体的には、紫外線を照射し、所定の距離で分光光度計によって光強度Ｉ０を測定する。次に、光源と分光光度計の間に、当該シートを配置して、同様に光強度Ｉを測定する。この際、Ｉ／Ｉ０が厚さ０．２ｍｍにおける分光透過率となる。 Here, the spectral transmittance of 60% or more at a thickness of 0.2 mm means that a sheet of the resin constituting the resin member 17 is formed into a sheet with a thickness of 0.2 mm, and light incident from one side of the sheet (for example, light A dose of 3000 mJ/cm) is the transmittance to the other. Specifically, ultraviolet rays are irradiated, and the light intensity I0 is measured with a spectrophotometer at a predetermined distance. Next, the sheet is placed between the light source and the spectrophotometer, and the light intensity I is similarly measured. At this time, I/I0 is the spectral transmittance at a thickness of 0.2 mm.
なお、透過率の対数とシート厚みとは比例関係にある。具体的には、シート厚みをｔとし、透過率をＴとすると、ｔ＝－Ｄｐ×ｌｏｇ１０Ｔとなる。ここで、Ｄｐは、硬化深度であり、シート厚みの増加に伴う透過率の減少（対数）のグラフの傾きとして表せられる。したがって、０．２ｍｍ厚以外のシートを用いて評価を行う場合には、上記式によって、そのシートの厚みに応じた透過率の範囲を算出すればよい。 Note that the logarithm of the transmittance and the sheet thickness are in a proportional relationship. Specifically, when the sheet thickness is t and the transmittance is T, t=−Dp×log10T. Here, Dp is the cure depth, which is expressed as the slope of a graph of decrease in transmittance (logarithmic) with increasing sheet thickness. Therefore, when evaluation is performed using a sheet with a thickness other than 0.2 mm, the transmittance range according to the thickness of the sheet may be calculated by the above formula.
なお、透過率は、光開始剤の添加量によって調整することができる。ここで、透過率が高すぎると、樹脂部材１７を視認することが困難となり、目視での品質確認が困難となるため、透過率は９０％以下であることが望ましい。 The transmittance can be adjusted by adjusting the amount of photoinitiator added. Here, if the transmittance is too high, it becomes difficult to visually recognize the resin member 17, and it becomes difficult to visually check the quality. Therefore, the transmittance is preferably 90% or less.
なお、樹脂部材１７の透過率を向上させたとしても、導線１３と端子１との隙間が狭くなりすぎると、反射回数が増えるため、反射に伴う光の減衰によって、紫外線が導線１３の影部に十分に回り込みにくくなる。このため、導線１３と端子１との隙間を適切に設定することが望ましい。
Even if the transmittance of the resin member 17 is improved, if the gap between the conductor 13 and the
例えば、被覆圧着部９の圧着の後に、樹脂部材１７を硬化する場合において、導線１３と端子１との隙間は、被覆部１５の端面と導線圧着部７までの距離と、被覆部１５の端面における導線１３と端子１との距離によって形成される。この場合、端子付き電線１０の長手方向の断面における、被覆部１５の端面と導線圧着部７までの距離が０．１ｍｍ以上であることが望ましく、被覆部１５の端面における導線１３と端子１との距離が、０．１ｍｍ以上であることが望ましい。このようにすることで、光が隙間に回り込みやすく、導線１３の影部の樹脂部材１７を硬化させることができる。なお、被覆部１５の端面における導線１３と端子１との距離は、概ね、被覆部１５の厚みと言い換えることができる。
For example, when the resin member 17 is cured after the crimping of the covering crimping portion 9, the gap between the conductor wire 13 and the
なお、樹脂部材１７は、紫外線硬化のみではなく、紫外線硬化と湿気硬化、嫌気硬化、熱硬化などを組み合わせたハイブリッド硬化型であってもよい。このようにすることで、紫外線の照射困難な部位も容易に硬化させることができる。 In addition, the resin member 17 may be of a hybrid curing type in which ultraviolet curing, moisture curing, anaerobic curing, heat curing, etc. are combined in addition to ultraviolet curing. By doing so, it is possible to easily cure a portion which is difficult to be irradiated with ultraviolet rays.
また、硬化させた樹脂部材１７の厚さ２００μｍのシートを作製し、ＪＩＳ Ｋ７１１３により２５℃破断伸びを測定した際の、樹脂部材１７の破断伸びは、１００％以上が好ましい。このように、樹脂部材１７の破断伸びが１００％以上であれば、圧着後における温度変化や外力などによる膨張や変形に対して、樹脂部材１７を容易に追従させることができる。 Further, when a 200 μm thick sheet of the cured resin member 17 is prepared and the breaking elongation at 25° C. is measured according to JIS K7113, the breaking elongation of the resin member 17 is preferably 100% or more. As described above, if the breaking elongation of the resin member 17 is 100% or more, the resin member 17 can easily follow expansion and deformation due to temperature change and external force after pressure bonding.
また、樹脂部材１７の、ＪＩＳ Ｋ６８５０による引張せん断接着強度は１ＭＰａ以上であることが望ましい。より詳細には、接着剤の引張せん断接着強さ試験方法により、錫めっき付銅板とアクリル板を重ね合わせて樹脂部材１７で接着した際の引張せん断接着強さ、アルミ板とアクリル板を重ね合わせて樹脂部材１７で接着した際の引張せん断接着強さ、および、軟質ＰＶＣ板とアクリル板とを重ね合わせて樹脂部材１７で接着した際の引張せん断接着強さの各々に対して、引張せん断接着強度は１ＭＰａ以上であることが望ましい。このようにすることで、樹脂部材１７が導線圧着部７や被覆部１５から剥がれて隙間が生じることを抑制することができる。 Moreover, it is desirable that the tensile shear adhesive strength of the resin member 17 according to JIS K6850 is 1 MPa or more. More specifically, by the tensile shear bond strength test method for adhesives, the tensile shear bond strength when a tin-plated copper plate and an acrylic plate are superimposed and bonded with the resin member 17, and the aluminum plate and the acrylic plate are superimposed. For each of the tensile shear bond strength when the resin member 17 is used to bond the soft PVC plate and the acrylic plate together and the resin member 17 is used to bond the soft PVC plate and the acrylic plate, the tensile shear bond It is desirable that the strength is 1 MPa or more. By doing so, it is possible to prevent the resin member 17 from being peeled off from the wire crimping portion 7 and the covering portion 15 to form a gap.
また、被覆圧着部９を圧着した後、さらに、図９に示すように、樹脂部材１７ａを塗布してもよい。このようにすることで、被覆圧着部９の圧着時に生じた隙間等に対しても、樹脂部材１７ａで被覆することができる。なお、この場合、樹脂部材１７と樹脂部材１７ａは、同じ樹脂であってもよいが、異なる樹脂であってもよい。例えば、樹脂部材１７は、浸透性が高い相対的に粘度が低いものを適用し、樹脂部材１７ａは、被覆厚を確保するために、相対的に粘度の高いものを適用することができる。 Further, after the covering pressure-bonding portion 9 is pressure-bonded, a resin member 17a may be further applied as shown in FIG. By doing so, it is possible to cover gaps and the like generated when the covering pressure-bonding portion 9 is pressure-bonded with the resin member 17a. In this case, the resin member 17 and the resin member 17a may be made of the same resin or may be made of different resins. For example, the resin member 17 may have high permeability and relatively low viscosity, and the resin member 17a may have relatively high viscosity in order to ensure a sufficient coating thickness.
また、本実施形態においては、図１０に示すように、導線圧着部７の本圧着時に、被覆圧着部９を仮圧着（仮圧着工程）してもよい。すなわち、樹脂塗布工程の前に、被覆圧着部９と被覆部１５を仮圧着してもよい。仮圧着では、被覆圧着部９は完全に被覆部１５と圧着されず、十分な隙間を維持しつつ、被覆圧着部９の形状を円形に近い形に整えることができる。これにより、導線圧着部７の本圧着時に、被覆圧着部９における電線が端子底面から所定量以上浮き上がってしまい、その後の樹脂塗布工程において樹脂部材１７ａを適切に塗布できなくなることを防ぐことができる。 Further, in the present embodiment, as shown in FIG. 10 , the covered crimping portion 9 may be temporarily crimped (temporary crimping step) at the time of the main crimping of the conductor crimping portion 7 . That is, the covering pressure-bonding portion 9 and the covering portion 15 may be temporarily pressure-bonded before the resin coating step. In the temporary pressure-bonding, the covering pressure-bonding portion 9 is not completely pressure-bonded to the covering portion 15, and the shape of the covering pressure-bonding portion 9 can be adjusted to a nearly circular shape while maintaining a sufficient gap. As a result, it is possible to prevent the electric wire in the covering crimping portion 9 from floating above the terminal bottom surface by a predetermined amount or more during the main crimping of the conductor crimping portion 7, thereby preventing the resin member 17a from being appropriately applied in the subsequent resin coating step. .
この状態から、図１１に示すように、樹脂部材１７を塗布することで、樹脂部材１７を効率よく被覆部１５と被覆圧着部９との隙間に浸透させることができる。このため、この後の被覆圧着部９の圧着によって、確実に樹脂部材１７によって、被覆部１５と被覆圧着部９との隙間を埋めることができる。 By applying the resin member 17 from this state, as shown in FIG. Therefore, the gap between the covering portion 15 and the covering pressure-bonding portion 9 can be reliably filled with the resin member 17 by the pressure-bonding of the covering pressure-bonding portion 9 thereafter.
ウレタンアクリルオリゴマー、アクリルモノマー、および光開始剤を主成分とする紫外線硬化と湿気硬化の硬化機構を持つ紫外線硬化型樹脂組成物を作成し、各種条件で端子付き電線に塗布した。この際、本組成物のオリゴマー成分、モノマー成分を調整して粘度の異なる樹脂部材を作成して、防食試験を実施した。 A UV-curable resin composition having a curing mechanism of UV-curing and moisture-curing, which consists mainly of urethane-acrylic oligomer, acrylic monomer, and photoinitiator, was prepared and applied to electric wires with terminals under various conditions. At this time, the oligomer component and the monomer component of the present composition were adjusted to prepare resin members having different viscosities, and an anticorrosion test was carried out.
防食性能は、図１２に示すように、水槽３１に塩水３３を貯留し、端子付き電線１０（端子１）を浸漬した後、端子－電線間の抵抗変動を測定することで評価を行った。塩水３３の濃度は、ＮａＣｌ３．０±０．５％とした。また、端子１の浸漬深さは３００±１０ｍｍとした。また、水没時間は２４時間とし、水没後６０±５℃で、９５±５％ＲＨ雰囲気に４８時間の環境で放置した後に、抵抗を測定し、塩水浸漬前の抵抗と比較した。なお、電線は、０．７５ｓｑサイズを用いた。
As shown in FIG. 12, the anti-corrosion performance was evaluated by storing salt water 33 in a water tank 31, immersing the terminal-equipped wire 10 (terminal 1), and then measuring the resistance variation between the terminal and the wire. The concentration of the salt water 33 was NaCl 3.0±0.5%. Moreover, the immersion depth of the
表１は、樹脂部材の粘度を変えて、被覆圧着前に樹脂部材を塗布した結果である。なお、以下の各実施例は、それぞれｎ＝１０で評価を行い、表中の、「防食性合否」については、ｎ＝１０の全ての抵抗変動が、１．０ｍΩ以下であったものを「◎」とし、２．０ｍΩ以下であったものを「○」とした。また、ｎ＝１０の一部の抵抗変動が２．０ｍΩを超えたものを「△」とし、ｎ＝１０の全ての抵抗変動が、２．０ｍΩを超えたものを「×」とした。また、各樹脂部材の粘度は塗布時の粘度である。 Table 1 shows the results of coating the resin member with different viscosities before covering and press-bonding. In addition, each of the following examples was evaluated at n = 10, and for "corrosion resistance pass/fail" in the table, all resistance fluctuations at n = 10 were 1.0 mΩ or less. ⊚”, and those with a value of 2.0 mΩ or less were evaluated as “◯”. In addition, when the resistance variation of a part of n=10 exceeded 2.0 mΩ, it was evaluated as "Δ", and when all the resistance variation of n=10 exceeded 2.0 mΩ, it was evaluated as "x". Also, the viscosity of each resin member is the viscosity at the time of application.
樹脂部材を被覆圧着前に塗布した場合には、樹脂部材の粘度が１０ｍＰａ・ｓ～２０００ｍＰａ・ｓの範囲において良好な結果となり、特に、樹脂部材の粘度が１０ｍＰａ・ｓ～１０００ｍＰａ・ｓの範囲においては、特に良好な結果となった。粘度が３０００ｍＰａ・ｓのものは、樹脂部材が十分に隙間に浸透せずに、防食性が劣った。 When the resin member is applied before coating pressure bonding, good results are obtained when the viscosity of the resin member is in the range of 10 mPa s to 2000 mPa s, particularly when the viscosity of the resin member is in the range of 10 mPa s to 1000 mPa s. gave particularly good results. When the viscosity was 3000 mPa·s, the resin member did not sufficiently permeate the gaps, resulting in poor anti-corrosion properties.
一方、表２は、樹脂部材の粘度を変えて、被覆圧着後に樹脂部材を塗布した結果である。なお、各評価方法は表１と同様である。 On the other hand, Table 2 shows the results of applying the resin member after pressure-bonding the coating by changing the viscosity of the resin member. In addition, each evaluation method is the same as that of Table 1.
被覆圧着後に樹脂部材を塗布すると、樹脂部材の粘度によらず、防食性が悪い結果となった。 When the resin member was applied after press-bonding the coating, the corrosion resistance was poor regardless of the viscosity of the resin member.
なお、他の径（０．５ｓｑ～２．５ｓｑ）の導線に対しても評価を行ったところ、同様の結果となった。 Similar results were obtained when conducting wires with other diameters (0.5 sq to 2.5 sq) were also evaluated.
以上説明したように、本実施形態によれば、樹脂部材１７によって、端子１と被覆導線１１との接続部を覆うため、効率良く防食効果を得ることができる。この際、被覆圧着前に樹脂部材１７を塗布するため、被覆圧着後における被覆部１５と被覆圧着部９との狭い隙間（特に、被覆部１５の端部と導線露出部の境界部周辺における導線１３と端子（圧着部５）との間の隙間）にも、確実に樹脂部材１７を塗布することができる。このため、被覆部１５と被覆圧着部９との隙間を伝い、被覆部１５の端部と導線露出部の境界部から水が浸入することを防止することができる。したがって、被覆圧着部９の長手方向の少なくとも一部において、被覆部１５と被覆圧着部９との間に、全周にわたって樹脂部材１７が塗布された、高い防食性を有する端子付き電線を得ることができる。 As described above, according to the present embodiment, since the resin member 17 covers the connecting portion between the terminal 1 and the covered conductor 11, the corrosion prevention effect can be obtained efficiently. At this time, since the resin member 17 is applied before the covering pressure bonding, the narrow gap between the covering portion 15 and the covering pressure bonding portion 9 after the covering pressure bonding (especially, the conductor around the boundary portion between the end portion of the covering portion 15 and the conductor exposed portion) The resin member 17 can also be reliably applied to the gap between 13 and the terminal (crimping portion 5). Therefore, it is possible to prevent water from entering through the gap between the covering portion 15 and the covering crimping portion 9 and entering from the boundary portion between the end portion of the covering portion 15 and the conductor exposed portion. Therefore, it is possible to obtain a highly corrosion-resistant electric wire with a terminal in which the resin member 17 is applied over the entire circumference between the covering portion 15 and the covering crimping portion 9 at least partly in the longitudinal direction of the covering crimping portion 9. can be done.
また、被覆圧着前に樹脂部材１７を硬化させることで、より深い部位まで紫外線を照射することができ、より確実に樹脂部材１７を硬化させることができる。また、被覆圧着時に、樹脂部材１７が飛散することを抑制することができる。 Further, by curing the resin member 17 before covering and press-bonding, it is possible to irradiate ultraviolet rays to a deeper portion, and the resin member 17 can be cured more reliably. Moreover, it is possible to suppress scattering of the resin member 17 at the time of pressure bonding.
また、この際、硬化後の樹脂部材１７の硬度が、被覆部１５の硬度よりも低ければ、樹脂部材１７が被覆圧着時に容易に変形し、被覆圧着部９および被覆部１５の変形に追従して、隙間を埋めることができる。 Further, at this time, if the hardness of the resin member 17 after curing is lower than the hardness of the covering portion 15 , the resin member 17 is easily deformed during covering pressure bonding, and follows the deformation of the covering pressure bonding portion 9 and the covering portion 15 . can fill in the gaps.
また、被覆圧着後に樹脂部材１７を硬化させることもできる。この場合には、被覆圧着時における、樹脂部材１７の流動性が良好であるため、樹脂部材１７を狭い隙間にも確実に塗布することができる。 Also, the resin member 17 can be cured after the cover pressure bonding. In this case, since the fluidity of the resin member 17 is good at the time of cover pressure bonding, the resin member 17 can be reliably applied even to a narrow gap.
また、樹脂部材１７を塗布する前に、被覆圧着部を仮圧着して、形状を整えることで、樹脂部材１７の流れ落ちなどを抑制することができる。 Moreover, before the resin member 17 is applied, the covering pressure-bonding portion is temporarily pressure-bonded to adjust the shape, thereby suppressing the resin member 17 from flowing down.
また、被覆圧着後にさらに樹脂部材１７ａを塗布することで、より確実に被覆部１５と被覆圧着部９との隙間を埋めることができる。 Further, by further applying the resin member 17a after the covering pressure bonding, the gap between the covering portion 15 and the covering pressure bonding portion 9 can be more reliably filled.
