Description

本発明は、モールドコネクタ付きの電線に関するもので、特に、自動車に配索する１本の電線端末から端子を突設したコネクタとして好適に用いられるものである。   The present invention relates to an electric wire with a molded connector, and in particular, is suitably used as a connector in which a terminal protrudes from one electric wire terminal arranged in an automobile.

自動車等の被水領域に配線する電線の端末にコネクタを接続する場合、コネクタの開口部から浸入した水がコネクタ内の芯線露出部に至り、該芯線露出部の腐食や断線が生じることを防止する種々の防水コネクタが提案されている。該防水コネクタの一つとして、電線端末の端子をモールドして成形したモールドコネクタとしている場合がある。   When connecting a connector to the end of an electric wire wired to a wet area such as an automobile, water that has entered from the opening of the connector reaches the core wire exposed part in the connector and prevents the core wire exposed part from being corroded or broken. Various waterproof connectors have been proposed. As one of the waterproof connectors, there is a case where a molded connector is formed by molding a terminal of an electric wire terminal.

図７に、従来の電線の端末に形成したモールドコネクタの一例を示す。（特開２００２−２０３６１５号（特許文献１）参照）
該モールドコネクタ１は、複数の電線２の端末を皮剥ぎして芯線を露出させ、この芯線露出部２ａに端子３Ａ、３Ｂの電線接続部３ａ、３ｂを加締め接続した状態の該芯線露出部２ａ全体と電線２の端末被覆部２ｂの外周に樹脂４をモールドして形成している。 FIG. 7 shows an example of a molded connector formed at the end of a conventional electric wire. (Refer to Unexamined-Japanese-Patent No. 2002-203615 (patent document 1))
The molded connector 1 peels off the ends of the plurality of electric wires 2 to expose the core wire, and the core wire exposed portion in a state where the wire connecting portions 3a and 3b of the terminals 3A and 3B are crimped and connected to the core wire exposed portion 2a. The resin 4 is molded and formed on the outer periphery of the entire 2a and the terminal covering portion 2b of the electric wire 2.

このように、電線２の芯線露出部２ａから端末被覆部２ｂまでを樹脂４で被覆することにより、電線２の外周に付着した水が伝い流れて端末に至ることを防ぎ、前記芯線露出部２ａの浸水および腐食を防止することができる。   Thus, by covering the core wire exposed portion 2a of the electric wire 2 to the terminal covering portion 2b with the resin 4, the water adhering to the outer periphery of the electric wire 2 is prevented from flowing and reaching the terminal, and the core exposed portion 2a. Can prevent flooding and corrosion.

しかしながら、この種のモールドコネクタ１においても、樹脂４を電線２の端末被覆部２ｂの外周面に完全に密着させることは難しく、僅かでも隙間があくと、その隙間からコネクタ１内に水が浸入し、前記芯線露出部２ａに水が至る場合がある。   However, even in this type of molded connector 1, it is difficult to completely adhere the resin 4 to the outer peripheral surface of the terminal covering portion 2b of the electric wire 2, and if there is even a slight gap, water enters the connector 1 from the gap. However, water may reach the core wire exposed portion 2a.

このような問題を解決するために、前記モールドコネクタ１は、さらに、端子３Ａ、３Ｂの電線接続部３ａ、３ｂと電線２の端末被覆部２ｂとの間の芯線露出部２ａにハンダを十分に浸みこませたハンダ浸透導体部領域５を形成し、該ハンダ浸透導体部領域５から端末被覆部２ｂまでの外周に熱収縮チューブ６を密着被覆して防水処理を施している。この熱収縮チューブ６による密着被覆後に、該熱収縮チューブ６の外周に前記樹脂４をモールドすることにより、芯線露出部２ａへの水の浸透をより有効に防止できるとしている。
しかしながら、前記防水処理工程が加わることにより、工数が増え、コスト高となる点に課題がある。 In order to solve such a problem, the molded connector 1 further sufficiently solders the core wire exposed portion 2a between the wire connecting portions 3a and 3b of the terminals 3A and 3B and the terminal covering portion 2b of the wire 2. A soaked solder permeation conductor region 5 is formed, and a heat-shrinkable tube 6 is tightly coated on the outer periphery from the solder permeation conductor portion region 5 to the terminal covering portion 2b for waterproofing. After the heat-shrinkable tube 6 is tightly coated, the resin 4 is molded on the outer periphery of the heat-shrinkable tube 6 to prevent water penetration into the core wire exposed portion 2a more effectively.
However, there is a problem in that the number of steps increases and the cost increases due to the addition of the waterproofing process.

また、他の防水処理方法として、図８に示すように、モールドコネクタ８の首下位置の電線引出部８ａの周囲に、電線７の絶縁被覆部７ａからコネクタ８の端面部にかけてシリコンシーラント９を塗布して、前記電線引出部８ａの周縁の隙間をシールする方法が知られている。
しかしながら、このシリコンシーラントによる防水処理も、シリコンとの密着性向上のために電線７の絶縁被覆７ａを脱脂する工程、プライマー処理工程、シリコンシーラント塗布工程、乾燥工程という複数の工程を必要とし、やはり工数が多く、コスト高となる点に問題がある。 As another waterproofing treatment method, as shown in FIG. 8, a silicon sealant 9 is provided around the wire lead-out portion 8 a at a position under the neck of the molded connector 8 from the insulating coating portion 7 a of the wire 7 to the end surface portion of the connector 8. A method of applying and sealing a gap at the periphery of the wire lead-out portion 8a is known.
However, this waterproofing treatment with a silicon sealant also requires a plurality of steps of degreasing the insulating coating 7a of the electric wire 7 for improving adhesion with silicon, a primer treatment step, a silicon sealant application step, and a drying step. There is a problem in that the man-hours are large and the cost is high.

特開２００２−２０３６１５号公報JP 2002-203615 A

本発明は前記問題に鑑みてなされたもので、製造工程における工数が少なく、コスト低減を図ることができると共に、優れた防水性を備えるモールドコネクタ付きの電線の提供を課題としている。   The present invention has been made in view of the above problems, and it is an object of the present invention to provide an electric wire with a molded connector having a small number of man-hours in the manufacturing process and capable of reducing cost and having excellent waterproofness.

前記問題を解決するために、本発明は、芯線を絶縁被覆で被覆している被覆電線の端末より芯線を露出させ、該芯線に端子を接続し、該端子の電気接触部は露出させると共に該端子の電線接続部および該端子と接続される前記被覆電線の端末を樹脂モールドしてコネクタを一体に設けているモールドコネクタ付きの電線であって、
前記被覆電線の絶縁被覆の表面に凹凸部を予め設けており、該絶縁被覆の表面と前記モールドコネクタとの接合面は凹凸嵌合形状となっていることを特徴とするモールドコネクタ付きの電線を提供している。 In order to solve the above problems, the present invention exposes the core wire from the end of the covered electric wire covering the core wire with an insulating coating, connects the terminal to the core wire, exposes the electrical contact portion of the terminal, and A wire with a molded connector in which a connector is integrally provided by resin-molding a terminal of the terminal and the terminal of the covered electric wire connected to the terminal,
An electric wire with a molded connector, wherein an uneven portion is provided in advance on the surface of the insulating coating of the coated electric wire, and a joint surface between the surface of the insulating coating and the molded connector has an uneven fitting shape. providing.

このように、被覆電線の絶縁被覆の表面に凹凸部を設け、該絶縁被覆の表面と前記モールドコネクタとの接合面を凹凸嵌合形状とすることにより、前記芯線露出部に至るまでの前記接合面の沿面距離を長くすることができる。また、前記凹凸部を形成する絶縁被覆のゴム弾性により、該絶縁被覆の表面とモールドコネクタとの接合面の密着性を高めることができる。よって、このような防水構造を備えたモールドコネクタ付き電線は、被覆電線の表面に付着した水が絶縁被覆の表面を伝ってコネクタ内に浸入することを前記凹凸嵌合部によって堰き止めることができるため、コネクタ内の前記芯線露出部の浸水を防ぎ、該芯線露出部の腐食、断線を有効に防止することができる。   In this way, by providing an uneven portion on the surface of the insulation coating of the covered electric wire, and forming the joint surface between the surface of the insulation coating and the mold connector into an uneven fitting shape, the bonding up to the core wire exposed portion is performed. The creepage distance of the surface can be increased. In addition, due to the rubber elasticity of the insulating coating forming the concavo-convex portion, the adhesion of the surface of the insulating coating and the joint surface of the mold connector can be enhanced. Therefore, the electric wire with a molded connector having such a waterproof structure can prevent the water adhering to the surface of the covered electric wire from entering the connector through the surface of the insulating coating by the uneven fitting portion. Therefore, it is possible to prevent the core wire exposed portion in the connector from being flooded, and to effectively prevent corrosion and disconnection of the core wire exposed portion.

また、前記防水構造は簡易な構造であるうえ、従来のように樹脂モールド前の前処理や、樹脂モールド後の後処理が不要となるため、工数を削減でき、コスト低減も図ることができる。   In addition, the waterproof structure is a simple structure, and the pre-treatment before the resin molding and the post-treatment after the resin molding are not required as in the prior art, so that the number of steps can be reduced and the cost can be reduced.

前記絶縁被覆の表面に設ける凹凸部は周方向に連続する環状のＶ状凹凸部とし、該凹凸部を長さ方向に連続させて鋸刃状とし、あるいは、
前記凹凸部は周方向に連続する環状の円弧状凹部と円弧状山部とし、該凹凸部を長さ方向に連続する波形状としている。 The concavo-convex portion provided on the surface of the insulating coating is an annular V-shaped concavo-convex portion continuous in the circumferential direction, and the concavo-convex portion is continuous in the length direction to have a saw blade shape, or
The concavo-convex part has an annular arc-shaped concave part and an arc-shaped peak part that are continuous in the circumferential direction, and the concavo-convex part has a wave shape that is continuous in the length direction.

前記絶縁被覆の表面に設ける凹凸部は前記モールドコネクタとの接合部のみに部分的に設け、あるいは、前記被覆電線の全長に設けている。
即ち、前記凹凸部は、モールドコネクタとの接合部にさえ設ければ、絶縁被覆表面とモールドコネクタとの接合部に前記凹凸嵌合形状を形成でき、モールドコネクタに至った水がコネクタ内に浸入することを堰き止めることができるが、さらに、被覆電線の全長に凹凸部を設ければ、絶縁被覆の表面に付着した水が該絶縁被覆の表面を伝い流れることを阻止でき、被水領域で付着した水が端末のモールドコネクタにまで至ることを防止できるため、芯線露出部の浸水を一層有効に防ぐことができる。 The uneven portion provided on the surface of the insulation coating is provided partially only at the joint portion with the mold connector or provided over the entire length of the covered electric wire.
That is, as long as the concave and convex portions are provided only at the joint portion with the mold connector, the concave and convex fitting shape can be formed at the joint portion between the insulating coating surface and the mold connector, and water reaching the mold connector enters the connector. However, if an uneven portion is provided on the entire length of the covered electric wire, it is possible to prevent water adhering to the surface of the insulating coating from flowing along the surface of the insulating coating. Since it is possible to prevent the adhered water from reaching the terminal mold connector, it is possible to more effectively prevent the core wire exposed portion from being submerged.

前記端子は前記電気接触部にボルト穴を設けていると共に、該電気接触部に連続して芯線加締めバレル、絶縁被覆加締めバレルを設けたボルト締め用の圧着端子からなり、
前記電気接触部を前方に突出させ、前記芯線加締めバレル、絶縁被覆加締めバレルおよび該絶縁被覆加締めバレルに連続する被覆電線端末に前記モールドコネクタを設けている。 The terminal is provided with a bolt hole in the electrical contact portion, and is composed of a crimp terminal for bolt tightening provided with a core wire caulking barrel and an insulation coating caulking barrel continuously with the electric contact portion,
The electrical contact portion protrudes forward, and the molded connector is provided on the core wire crimping barrel, the insulating coating crimping barrel, and the coated electric wire terminal continuing to the insulating coating crimping barrel.

上述したように、本発明によれば、被覆電線の絶縁被覆の表面に凹凸部を設け、該絶縁被覆の表面とモールドコネクタとの接合面を凹凸嵌合形状とすることにより、モールドコネクタ内の芯線露出部に至るまでの前記接合面の沿面距離を長くすることができる。また、前記凹凸部を形成する絶縁被覆のゴム弾性により、該絶縁被覆の表面とモールドコネクタとの接合面の密着性を高めることができる。よって、このような防水構造を備えたモールドコネクタ付き電線は、被覆電線の表面に付着した水が絶縁被覆の表面を伝ってコネクタ内に浸入し前記芯線露出部に至ることを、前記凹凸嵌合部によって有効に堰き止めることができ、優れた防水性を備えることができる。
また、前記防水構造は簡易な構造であるうえ、従来のように樹脂モールド前の前処理や、樹脂モールド後の後処理が不要となるため、工数を削減でき、コスト低減も図ることができる。 As described above, according to the present invention, a concave and convex portion is provided on the surface of the insulating coating of the covered electric wire, and the joint surface between the surface of the insulating coating and the molded connector has a concave and convex fitting shape. The creepage distance of the joint surface up to the core wire exposed portion can be increased. In addition, due to the rubber elasticity of the insulating coating forming the concavo-convex portion, the adhesion of the surface of the insulating coating and the joint surface of the mold connector can be enhanced. Therefore, the wire with a molded connector having such a waterproof structure is such that the water adhering to the surface of the covered wire enters the connector through the surface of the insulating coating and reaches the exposed portion of the core wire. It can be effectively dammed by the part, and can be provided with excellent waterproofness.
In addition, the waterproof structure is a simple structure, and the pre-treatment before the resin molding and the post-treatment after the resin molding are not required as in the prior art, so that the number of steps can be reduced and the cost can be reduced.

以下、本発明の実施形態を図面を参照して説明する。
図１乃至図３に、本発明の第１実施形態にかかるモールドコネクタ付きの電線１０を示す。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show an electric wire 10 with a molded connector according to a first embodiment of the present invention.

電線１０は、図２（Ａ）（Ｂ）に示すように、芯線１１を絶縁被覆１２で被覆した被覆電線であり、端末に穴あき端子２０を接続している。該電線１０は、本実施形態では、ハイブリッド電気自動車のエンジンルーム内に配索し、図１に示すように、前記穴あき端子２０をモーター５０の接続部５１にボルト５２とナット５３とで締結接続する。   As shown in FIGS. 2A and 2B, the electric wire 10 is a covered electric wire in which a core wire 11 is covered with an insulating coating 12, and a perforated terminal 20 is connected to a terminal. In this embodiment, the electric wire 10 is routed in the engine room of the hybrid electric vehicle, and the perforated terminal 20 is fastened to the connecting portion 51 of the motor 50 with a bolt 52 and a nut 53 as shown in FIG. Connecting.

前記穴あき端子２０は、図２（Ａ）（Ｂ）に示すように、電気接触部２１にボルト穴２２を設けていると共に、該電気接触部２１に連続して芯線加締めバレル２３と絶縁被覆加締めバレル２４とからなる電線接続部を設けている。該穴あき端子２０は、電線１０の端末部の絶縁被覆１２を皮剥ぎして露出させた芯線１１に前記芯線加締めバレル２３を圧着して導通を得ると共に、前記絶縁被覆加締めバレル２４を電線１０の絶縁被覆部１３の端末に圧着している。   As shown in FIGS. 2 (A) and 2 (B), the holed terminal 20 is provided with a bolt hole 22 in the electrical contact portion 21 and is insulated from the core wire crimping barrel 23 continuously to the electrical contact portion 21. An electric wire connecting portion including a covering caulking barrel 24 is provided. The perforated terminal 20 is made conductive by crimping the core wire crimping barrel 23 to the exposed core wire 11 by peeling off the insulation coating 12 at the end portion of the electric wire 10, and the insulation coating crimping barrel 24. It is crimped to the end of the insulation coating portion 13 of the electric wire 10.

前記電線１０と前記穴あき端子２０との接続部分には、外周に樹脂３１をモールドしてモールドコネクタ３０を形成している。
詳しくは、前記芯線１１の露出部分、前記芯線加締めバレル２３、前記絶縁被覆加締めバレル２４、および該絶縁被覆加締めバレルに連続する端末被覆部１４を樹脂３１でモールドしてモールドコネクタ３０を形成し、該モールドコネクタ３０の前方から穴あき端子２０の電気接触部２１を突出させ、後方からは電線１０の絶縁被覆部１３を引き出している。 A molded connector 30 is formed by molding a resin 31 on the outer periphery of the connection portion between the electric wire 10 and the perforated terminal 20.
More specifically, the exposed portion of the core wire 11, the core wire crimping barrel 23, the insulation coating crimping barrel 24, and the terminal coating portion 14 continuing to the insulation coating crimping barrel are molded with a resin 31 to form a molded connector 30. The electrical contact portion 21 of the perforated terminal 20 is projected from the front of the molded connector 30 and the insulation coating portion 13 of the electric wire 10 is drawn from the rear.

前記電線１０の絶縁被覆１２の表面には、前記モールドコネクタ３０との接合領域Ａに当たる領域全体に予め凹凸部１５を形成している。該凹凸部１５は、周方向に連続する環状のＶ状凹凸部を長さ方向に連続させた鋸刃状としている。
前記凹凸部１５の形成に際しては、まず、芯線１１を被覆樹脂の押し出し成形機に通して芯線１１の外周に絶縁被覆１２の層を形成し、この押し出しの直後に、図３（Ａ）（Ｂ）に示すように、内周に凹凸４３、４４を設けた上下型４１、４２を絶縁被覆１２の表面に押し当てて形成する。 On the surface of the insulating coating 12 of the electric wire 10, the concavo-convex portion 15 is formed in advance in the entire region corresponding to the bonding region A with the mold connector 30. The concavo-convex portion 15 has a saw blade shape in which an annular V-shaped concavo-convex portion continuous in the circumferential direction is continued in the length direction.
When forming the uneven portion 15, first, the core wire 11 is passed through a coating resin extrusion molding machine to form an insulating coating 12 layer on the outer periphery of the core wire 11. Immediately after this extrusion, FIG. ), The upper and lower molds 41 and 42 provided with irregularities 43 and 44 on the inner periphery are formed by pressing against the surface of the insulating coating 12.

前記構成のモールドコネクタ付き電線１０は、絶縁被覆１２の表面に予め前記凹凸部１５を形成していることにより、図２（Ａ）（Ｂ）に示すように、該凹凸部１５の形成領域においてモールドコネクタ３０と絶縁被覆１２との接合面が凹凸嵌合形状となる。よって、絶縁被覆１２とモールドコネクタ３０との接合領域Ａの接合面Ｂの沿面長さを長く確保することができる。   In the electric wire 10 with a molded connector having the above-described configuration, the uneven portion 15 is formed on the surface of the insulating coating 12 in advance, so that in the region where the uneven portion 15 is formed, as shown in FIGS. The joint surface between the mold connector 30 and the insulating coating 12 has an uneven fitting shape. Therefore, a long creepage length of the joint surface B of the joint region A between the insulating coating 12 and the molded connector 30 can be secured.

また、前記接合領域Ａにはモールドコネクタ３０と絶縁被覆１２との凹凸嵌合部１６が形成されると共に、絶縁被覆１２のゴム弾性によりその嵌合の密着性を高めることができるため、優れたシール性を備えることができる。   Moreover, since the uneven | corrugated fitting part 16 of the mold connector 30 and the insulation coating 12 is formed in the said joining area | region A, and the adhesiveness of the fitting can be improved with the rubber elasticity of the insulation coating 12, it was excellent. Sealability can be provided.

これらにより、被水領域において電線１０の絶縁被覆１２の表面に付着した水が絶縁被覆１２の表面を伝いモールドコネクタ３０の電線引出口３２の僅かな隙間からコネクタ内部に浸入しようとしても、シール性の高い前記凹凸嵌合部１６により水の浸入を阻止することができるうえ、前記接合面Ｂの凹凸嵌合形状により前記電線引出口３２から芯線１１の露出部に到達するまでの距離が長いため、芯線１１に水が到達することを有効に防ぐことができる。よって、優れた防水性を備えることができ、芯線１１の腐食や断線を防止することができる。   As a result, even if water adhering to the surface of the insulating coating 12 of the electric wire 10 passes through the surface of the insulating coating 12 and enters the inside of the connector from a slight gap of the electric wire outlet 32 of the molded connector 30 in the wet area, the sealing performance In addition, it is possible to prevent water from entering due to the high concave / convex fitting portion 16, and because the concave / convex fitting shape of the joint surface B increases the distance from the wire outlet 32 to the exposed portion of the core wire 11. It is possible to effectively prevent water from reaching the core wire 11. Therefore, excellent waterproofness can be provided, and the core wire 11 can be prevented from being corroded or disconnected.

また、前記防水構造は樹脂３１のモールド成形と同時に完成する簡易なものであり、樹脂モールド前の前処理工程や樹脂モールド後の後処理工程も不要となる。よって、製造工程における工数を削減でき、コスト低減を図ることができる。   Further, the waterproof structure is a simple one that is completed simultaneously with the molding of the resin 31, and a pre-processing step before the resin molding and a post-processing step after the resin molding are not required. Therefore, the man-hour in a manufacturing process can be reduced and cost reduction can be aimed at.

前記凹凸部１５は、図４に示す変形例１のように、周方向に連続する円弧状凹部１５ａと円弧状山部１５ｂとを長さ方向に交互に連続させてなる波形状としてもよい。   As in the first modification shown in FIG. 4, the uneven portion 15 may have a wave shape in which arc-shaped concave portions 15 a and arc-shaped mountain portions 15 b that are continuous in the circumferential direction are alternately continued in the length direction.

図５に本発明の第２実施形態を示す。
第２実施形態では、前記凹凸部１５を被覆電線１０の全長に設けている。その他の構成は前記第１実施形態と同一であるため、同一符合を付して説明を省略する。 FIG. 5 shows a second embodiment of the present invention.
In the second embodiment, the uneven portion 15 is provided over the entire length of the covered electric wire 10. Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

このように全長に凹凸部１５を形成することにより、水が電線１０の絶縁被覆１２の表面を伝い流れることを防止できるため、被水領域で付着した水がモールドコネクタ３０にまで至ることを有効に阻止でき、防水性を一層高めることができる。   By forming the uneven portion 15 over the entire length in this way, it is possible to prevent water from flowing along the surface of the insulating coating 12 of the electric wire 10, so that it is effective that the water adhering to the wet area reaches the mold connector 30. Can be prevented, and the waterproofness can be further enhanced.

図６に本発明の第３実施形態に係るモールドコネクタ付き電線１０ーＡを示す。
該電線１０ーＡは、芯線１１を絶縁被覆１２で被覆した被覆電線であり、その端末には、オス端子２５を接続していると共にメス型のモールドコネクタ３５を形成している。該電線１０ーＡは、自動車のエンジンルーム内に配索し、前記モールドコネクタ３５と相手方コネクタ５５とを嵌合させて、該相手方コネクタ５５内に収容されたメス端子５６を前記オス端子２５と接続させる。 FIG. 6 shows an electric wire 10-A with a molded connector according to a third embodiment of the present invention.
The electric wire 10-A is a covered electric wire in which the core wire 11 is covered with an insulating coating 12, and a male terminal 25 is connected to a terminal of the electric wire 10-A and a female molded connector 35 is formed. The electric wire 10-A is routed in the engine room of the automobile, and the molded connector 35 and the mating connector 55 are fitted together, and the female terminal 56 accommodated in the mating connector 55 is connected to the male terminal 25. Connect.

前記オス端子２５は、オス型の電気接触部２６と、該電気接触部２６に連続して芯線加締めバレル２７と絶縁被覆加締めバレル２８とを設けている。該オス端子２５は、電線１０ーＡの端末部の絶縁被覆１２を皮剥ぎして露出させた芯線１１に前記芯線加締めバレル２７を圧着して導通を得ると共に、前記絶縁被覆加締めバレル２８を電線１０ーＡの絶縁被覆部１３の端末に圧着している。   The male terminal 25 is provided with a male electric contact portion 26, and a core wire caulking barrel 27 and an insulating coating caulking barrel 28 that are continuous with the electric contact portion 26. The male terminal 25 is electrically connected by crimping the core crimping barrel 27 to the exposed core wire 11 by peeling off the insulation coating 12 at the end of the electric wire 10-A, and the insulation coating crimping barrel 28. Is crimped to the end of the insulating coating 13 of the electric wire 10-A.
