Description

本発明は、端子付電線の端末に熱収縮チューブが取り付けられてなる熱収縮チューブ付電線に関するものである。   The present invention relates to an electric wire with a heat-shrinkable tube in which a heat-shrinkable tube is attached to the end of an electric wire with a terminal.

従来から、自動車などの電装系では、被覆電線の端末において露出された芯線に対して端子金具が圧着などにより取り付けられてなる端子付電線が広く採用されている。端子付電線の端子金具は、例えば、特開２０１３−２５４６５７号公報（特許文献１）に記載されているように、先端側に設けられて相手方の端子に接続される接続部と、基端側に設けられて被覆電線の絶縁被覆の外周面に圧着される被覆圧着部と、それらの間に設けられて芯線に圧着される芯線圧着部を備えている。そして、防食の目的から、芯線圧着部と被覆圧着部の周囲には熱収縮チューブが装着されて加熱による熱収縮により密着固定されるようになっている。   2. Description of the Related Art Conventionally, in an electrical system such as an automobile, a terminal-attached electric wire in which a terminal fitting is attached to a core wire exposed at the end of a covered electric wire by crimping or the like is widely used. For example, as described in JP 2013-254657 A (Patent Document 1), a terminal fitting of a terminal-attached electric wire is provided on a distal end side and connected to a counterpart terminal, and a proximal end side And a coated crimping portion that is crimped to the outer peripheral surface of the insulating coating of the coated electric wire, and a core wire crimping portion that is disposed between them and is crimped to the core wire. For the purpose of anticorrosion, a heat-shrinkable tube is attached around the core crimping part and the covering crimping part, and is closely fixed by heat shrinkage due to heating.

ところで、熱収縮チューブの先端側の開口部が熱収縮により縮径して被着される芯線圧着部と接続部との間を連結する連結部には、連結部上に載置された芯線端部の径寸法に起因して芯線端部の上面と連結部の表面により比較的大きな段差が形成される。それゆえ、かかる段差により縮径した熱収縮チューブの開口部と連結部の間に隙間が生じ、防水性が確保できないという問題が生じ得る。かかる問題に対して、芯線圧着部から接続部に至る連結部の長さを長く確保して、その分熱収縮チューブの長さ寸法を長くすることが行われていた。これにより、突出高さの大きな芯線圧着部から延び出す熱収縮チューブの開口部を扁平な状態で連結部を挟んで密着することができることから、防食性を確保されるのである。   By the way, the end of the core wire placed on the connecting portion is connected to the connecting portion that connects the core wire crimping portion and the connecting portion to which the opening portion on the distal end side of the heat shrinkable tube is reduced in diameter by heat shrinkage and is attached. Due to the diameter of the portion, a relatively large step is formed by the upper surface of the end portion of the core wire and the surface of the connecting portion. Therefore, a gap may be formed between the opening and the connecting portion of the heat-shrinkable tube having a reduced diameter due to such a step, resulting in a problem that waterproofness cannot be ensured. In order to deal with such a problem, it has been practiced to secure a long connecting portion from the core crimping portion to the connecting portion and to increase the length of the heat shrinkable tube accordingly. Thereby, since the opening part of the heat contraction tube extended from the core wire crimping part with big protrusion height can be contact | adhered on both sides of a connection part in the flat state, corrosion resistance is ensured.

しかしながら、このような構造では、端子金具の大型化が避けられず、有効な対策とは言い難かった。そこで、特開２０１４−１４６５３８号公報（特許文献２）の図２に記載されているように、芯線圧着部と接続部との間に位置する連結部に対して樹脂成形品である閉塞部材を配設する構造が提案されている。かかる構造によれば、熱収縮チューブの収縮方向において熱収縮チューブの開口部を芯線端部よりも大きく離隔して位置する連結部ではなく芯線端部からの離隔距離が小さい閉塞部材の周囲に密着させることができる。これにより、芯線圧着部から接続部に至る連結部の長さを長く確保しなくても熱収縮チューブと端子金具の間に隙間が生ずることがなく防食性を確保することが可能となる。   However, such a structure inevitably increases the size of the terminal fitting, and is not an effective measure. Therefore, as described in FIG. 2 of Japanese Patent Application Laid-Open No. 2014-146538 (Patent Document 2), a blocking member that is a resin molded product is provided for the connecting portion positioned between the core wire crimping portion and the connecting portion. A structure for disposing has been proposed. According to such a structure, the opening of the heat-shrinkable tube in the shrinking direction of the heat-shrinkable tube is closely attached to the periphery of the closing member that is not separated from the end of the core wire, rather than the connecting portion that is located farther than the end of the core wire. Can be made. Thereby, even if it does not ensure the length of the connection part from a core wire crimping part to a connection part long, a clearance gap does not arise between a heat contraction tube and a terminal metal fitting, and it becomes possible to ensure corrosion resistance.

しかしながら、閉塞部材が配設される端子金具の連結部には一対の側壁を形成する必要があり、複雑な構造の端子金具が必要となる。また、閉塞部材により一対の側壁が形成された連結部の内側を隙間なく閉塞する必要があるが、樹脂成形品である閉塞部材の寸法公差などにより防水性を安定して確保することが困難となる場合もあった。   However, it is necessary to form a pair of side walls at the connecting portion of the terminal fitting on which the closing member is disposed, and a terminal fitting having a complicated structure is required. In addition, it is necessary to close the inside of the connecting portion in which the pair of side walls are formed by the closing member without gaps, but it is difficult to stably ensure waterproofness due to the dimensional tolerance of the closing member which is a resin molded product. There was also a case.

特開２０１３−２５４６５７号公報JP 2013-254657 A 特開２０１４−１４６５３８号公報JP 2014-146538 A

本発明は、上述の事情を背景に為されたものであって、その解決課題は、複雑な構造の端子金具を必要とすることなく、寸法公差の影響を低減して熱収縮チューブによる防食性を安定して確保することができる、新規な構造の熱収縮チューブ付電線を提供することにある。   The present invention has been made in the background of the above-mentioned circumstances, and its solution is to eliminate the influence of dimensional tolerances without requiring a complicated metal fitting, and to prevent corrosion by a heat-shrinkable tube. An object of the present invention is to provide an electric wire with a heat-shrinkable tube having a novel structure that can stably secure the above.

本発明の第一の態様は、芯線が絶縁被覆により覆われてなる被覆電線と、先端側に設けられて相手方の端子に接続される接続部と、基端側に設けられて前記被覆電線の前記絶縁被覆の外周面に圧着された被覆圧着部と、前記接続部と前記被覆圧着部の間に設けられて前記被覆電線の前記芯線に固着された芯線固着部とを有する端子金具と、前記芯線固着部と前記被覆圧着部の周囲に外挿されて接着剤を介して固着された熱収縮チューブと、を備えた熱収縮チューブ付電線において、前記芯線固着部と前記接続部を連結する連結部に弾性リングが外嵌されかつ弾性復元力により密着固定されることで、前記連結部の全周に亘って前記弾性リングが配設されており、前記弾性リングの外周面の全周に亘って、前記熱収縮チューブの先端側の開口部が密着固定されていることを特徴とする。   According to a first aspect of the present invention, there is provided a covered electric wire in which a core wire is covered with an insulating coating, a connecting portion provided on a distal end side and connected to a counterpart terminal, and provided on a proximal end side of the covered electric wire. A terminal fitting having a coated crimped portion crimped to an outer peripheral surface of the insulating coating, and a core wire fixing portion provided between the connecting portion and the coated crimped portion and fixed to the core wire of the coated wire; In a heat shrinkable tube-equipped electric wire comprising: a core wire fixing portion and a heat shrinkable tube which is extrapolated around the covering crimping portion and fixed via an adhesive, the connection for connecting the core wire fixing portion and the connection portion An elastic ring is externally fitted to the portion and is closely fixed by an elastic restoring force, so that the elastic ring is disposed over the entire circumference of the connecting portion, and over the entire circumference of the outer peripheral surface of the elastic ring. The opening on the tip side of the heat shrink tube Characterized in that it is tightly fixed.

本態様によれば、弾性リングの外周面の全周に亘って熱収縮チューブの先端側の開口部が密着固定されていることから、従来の如き熱収縮チューブの先端側の開口部を連結部に密着固定する場合に比して、熱収縮チューブの縮径方向における熱収縮チューブの先端側の開口部と密着固定領域（弾性リングの外周面）との間の離隔距離（段差）を大幅に低減することができる。それゆえ、熱収縮チューブの先端側の開口部を弾性リングの外周面に安定して密着固定することができる。これにより、従来の如き芯線端部と連結部間の段差に起因して熱収縮チューブと端子金具の間に隙間が生じる不具合を改善でき、防食性を確保することができる。   According to this aspect, since the opening on the distal end side of the heat shrinkable tube is tightly fixed over the entire circumference of the outer peripheral surface of the elastic ring, the opening on the distal end side of the conventional heat shrinkable tube is connected to the connecting portion. The separation distance (step) between the opening on the tip side of the heat-shrinkable tube and the tight-fixed region (the outer peripheral surface of the elastic ring) in the diameter-reducing direction of the heat-shrinkable tube is greatly Can be reduced. Therefore, the opening on the distal end side of the heat shrinkable tube can be stably and firmly fixed to the outer peripheral surface of the elastic ring. Thereby, the malfunction which a clearance gap produces between a heat-shrinkable tube and a terminal metal fitting resulting from the level | step difference between a core wire edge part and a connection part like the past can be improved, and corrosion resistance can be ensured.

しかも、端子金具の連結部に筒状の弾性リングが外嵌されかつ弾性復元力により密着固定されることで、弾性リングが連結部の全周に亘って配設されている。これにより、弾性リングと連結部間においても、連結部の全周に亘って弾性リングが密着固定されている。要するに、弾性リングの弾性復元力を巧く利用して、寸法公差などの影響を低減しつつ連結部と弾性リングの間の隙間の発生を防止して、安定した防食性を確保することができるのである。加えて、弾性リングを端子金具に外装固定すればよいことから、複雑な特定構造の端子金具を必要とせず、既存の端子金具を用いて構成できるのである。   In addition, the elastic ring is disposed over the entire circumference of the connecting portion by fitting a cylindrical elastic ring to the connecting portion of the terminal metal fitting and fixing it tightly by an elastic restoring force. Thereby, also between the elastic ring and the connecting portion, the elastic ring is tightly fixed over the entire circumference of the connecting portion. In short, by utilizing the elastic restoring force of the elastic ring, it is possible to prevent the occurrence of a gap between the connecting portion and the elastic ring while reducing the influence of dimensional tolerance and the like, and to ensure stable corrosion resistance. It is. In addition, since it is only necessary to externally fix the elastic ring to the terminal fitting, the terminal fitting having a complicated specific structure is not required and can be configured using the existing terminal fitting.

また、弾性リングが弾力性を有していることから、熱収縮チューブの先端側の開口部と弾性リング間および弾性リングと連結部間を一層有利に隙間なく密着して覆うことが可能となる。そして、熱収縮チューブが熱収縮して弾性リングの外周面に密着固定される際には、熱収縮チューブの収縮力により弾性リングが圧縮されている。それゆえ、高温の使用環境下で熱圧縮チューブが緩み、内部の接着剤が溶解した場合でも、弾性リングが弾性復帰することで熱収縮チューブの開口部と弾性リングの外周面の密着性が保持される。これにより、熱収縮チューブ内の接着剤が外部に流出して、接続部などへ悪影響を与える不具合も未然に防止できる。なお、弾性リング３８は、ＥＰＤＭ（エチレンプロピレンゴム）、ＡＣＭ（アクリルゴム）、ＥＶＡ（エチレン酢酸ビニルゴム）などのゴム材料によって一体的に形成されている。   Further, since the elastic ring has elasticity, it becomes possible to more closely adhere and cover the opening portion on the tip side of the heat shrinkable tube and the elastic ring and between the elastic ring and the connecting portion without any gap. . When the heat-shrinkable tube is heat-shrinked and firmly fixed to the outer peripheral surface of the elastic ring, the elastic ring is compressed by the shrinkage force of the heat-shrinkable tube. Therefore, even when the heat compression tube loosens and the internal adhesive dissolves under high-temperature usage conditions, the elastic ring returns elastically, so that the adhesion between the heat shrink tube opening and the outer peripheral surface of the elastic ring is maintained. Is done. Thereby, it is possible to prevent a problem that the adhesive in the heat-shrinkable tube flows out to the outside and adversely affects the connection part. The elastic ring 38 is integrally formed of a rubber material such as EPDM (ethylene propylene rubber), ACM (acrylic rubber), EVA (ethylene vinyl acetate rubber).

本発明の第二の態様は、前記第一の態様に記載のものにおいて、前記連結部に切欠部が設けられており、該切欠部の形成部位に前記弾性リングが外装されて密着固定されているものである。   According to a second aspect of the present invention, in the one described in the first aspect, a cutout portion is provided in the connection portion, and the elastic ring is externally fitted and fixedly fixed to a formation site of the cutout portion. It is what.

本態様によれば、連結部に設けた切欠部に弾性リングを外装することにより、弾性リングの連結部に対する位置決め固定を一層確実に行うことができる。それゆえ、既存の端子に切欠部を設けるだけで構成できるのである。さらに、かかる切欠部は、連結部を切り欠くことで形成できることから、材料費が増加するおそれもない。   According to this aspect, it is possible to more reliably position and fix the elastic ring with respect to the connecting portion by covering the cutout portion provided in the connecting portion with the elastic ring. Therefore, it can be configured only by providing a notch in an existing terminal. Furthermore, since such a notch part can be formed by notching a connection part, there is also no possibility that material cost will increase.

加えて、切欠部に筒状の弾性リングが挿通されて連結部の全周に亘って配設されていることから、弾性リングを端子金具の連結部に取付ける際に、切欠部を目印にして容易に取付けることができる。   In addition, since the cylindrical elastic ring is inserted through the notch and is arranged over the entire circumference of the connecting part, when attaching the elastic ring to the connecting part of the terminal fitting, the notch is used as a mark. Can be easily installed.

本発明の第三の態様は、前記第一または第二の態様に記載のものにおいて、前記弾性リングの底面が平坦とされているものである。   According to a third aspect of the present invention, in the first or second aspect, the bottom surface of the elastic ring is flat.

本態様によれば、弾性リングの底面が平坦とされていることから、例えば端子金具の接続部をボルト締結する場合には、弾性リングの底面が近隣部材と干渉してボルト締結が安定してできないという問題を解消することが可能となる。   According to this aspect, since the bottom surface of the elastic ring is flat, for example, when the connection portion of the terminal fitting is bolted, the bottom surface of the elastic ring interferes with a neighboring member and the bolt fastening is stable. It becomes possible to solve the problem of being unable.

本発明の第四の態様は、前記第一乃至第三の何れか一つの態様に記載のものにおいて、前記弾性リングの上面が山型とされているものである。   According to a fourth aspect of the present invention, in the one described in any one of the first to third aspects, the upper surface of the elastic ring has a mountain shape.

本態様によれば、弾性リングの上面が山型とされていることから、熱収縮チューブの先端側の開口部の形状（円筒形状）と弾性リングの上面の形状を沿うようにすることができる。これにより、径方向内方に熱収縮する熱収縮チューブの先端側の開口部と弾性リングの上面の間に隙間が発生することを一層有利に防止することが可能になる。   According to this aspect, since the upper surface of the elastic ring has a mountain shape, the shape (cylindrical shape) of the opening on the distal end side of the heat shrinkable tube and the shape of the upper surface of the elastic ring can be aligned. . As a result, it is possible to more advantageously prevent a gap from being generated between the opening on the distal end side of the heat-shrinkable tube that thermally shrinks inward in the radial direction and the upper surface of the elastic ring.

本発明の第五の態様は、前記第二乃至第四の何れか一つの態様に記載のものにおいて、前記切欠部が前記連結部の幅方向両側の対向する位置に設けられているものである。   According to a fifth aspect of the present invention, in the one according to any one of the second to fourth aspects, the notch portion is provided at an opposing position on both sides in the width direction of the connecting portion. .

本態様によれば、切欠部が連結部の幅方向両側の対向する位置に設けられていることから、弾性リングを連結部の周囲に均等な状態でより一層安定して位置決め固定することが可能となり、熱収縮チューブ付電線の製品ばらつきを低減することが可能となる。   According to this aspect, since the notch portions are provided at opposite positions on both sides in the width direction of the connecting portion, the elastic ring can be positioned and fixed more stably around the connecting portion in an even state. Thus, it is possible to reduce the product variation of the electric wire with the heat shrinkable tube.

本発明によれば、弾性リングの外周面の全周に亘って熱収縮チューブの先端側の開口部が密着固定されていることから、従来の如き芯線端部と連結部間の段差に起因して熱収縮チューブと端子金具の間に隙間が生じる不具合を改善でき、防食性を確保できる。しかも、弾性リングが連結部の全周に亘って配設されている。これにより、弾性リングの弾性復元力を巧く利用して、寸法公差などの影響を低減しつつ連結部と弾性リングの間の隙間の発生を防止して、安定した防食性を確保できる。加えて、弾性リングを連結部へ外装して密着固定するという簡単な構造で実現できることから、複雑な特定構造の端子金具を必要とせず、既存の端子金具を利用して構成できる。また、熱収縮チューブが熱収縮して弾性リングの外周面に密着固定される際に熱収縮チューブの収縮力により弾性リングが圧縮されていることから、高温の使用環境下で内部の接着剤が溶解した場合でも、弾性リングが弾性復帰することで熱収縮チューブの開口部と弾性リングの外周面の密着性が保持されて、接着剤が流出して接続部などへ悪影響を与える不具合も未然に防止できる。   According to the present invention, since the opening on the distal end side of the heat shrinkable tube is tightly fixed over the entire circumference of the outer peripheral surface of the elastic ring, it is caused by the step between the core end and the connecting portion as in the prior art. Therefore, it is possible to improve the problem that a gap is generated between the heat-shrinkable tube and the terminal fitting, and to ensure corrosion resistance. Moreover, the elastic ring is disposed over the entire circumference of the connecting portion. Accordingly, the elastic restoring force of the elastic ring can be skillfully utilized to prevent the occurrence of a gap between the connecting portion and the elastic ring while reducing the influence of dimensional tolerance and the like, thereby ensuring stable corrosion resistance. In addition, since it can be realized with a simple structure in which the elastic ring is externally attached to the connecting portion and fixed in close contact, it is possible to configure using existing terminal fittings without requiring a complicated terminal fitting with a specific structure. In addition, since the elastic ring is compressed by the contraction force of the heat-shrinkable tube when the heat-shrinkable tube is heat-shrinked and firmly fixed to the outer peripheral surface of the elastic ring, Even when melted, the elastic ring returns elastically, so that the adhesiveness between the opening of the heat shrinkable tube and the outer peripheral surface of the elastic ring is maintained. Can be prevented.

次に、本実施形態の熱収縮チューブ付電線１０の製造方法について説明する。先ず、被覆電線１２の端末側の絶縁被覆１８を剥いで芯線１４を露出させる。続いて、この被覆電線１２の外周側に熱収縮チューブ４４を遊挿して、端末よりも後方側（図１および図２中、下側）に移動させておく。そして、芯線１４が露出された被覆電線１２の端末を、被覆電線１２が端子金具１６の被覆圧着部２２の載置部２８上に載置され、かつ芯線１４が芯線固着部２４の載置部３２上に載置されるように配設する。   Next, the manufacturing method of the electric wire 10 with a heat contraction tube of this embodiment is demonstrated. First, the insulation coating 18 on the terminal side of the covered electric wire 12 is peeled to expose the core wire 14. Subsequently, the heat-shrinkable tube 44 is loosely inserted on the outer peripheral side of the covered electric wire 12 and moved to the rear side (lower side in FIGS. 1 and 2) from the terminal. Then, the end of the covered electric wire 12 with the core wire 14 exposed is covered on the placement portion 28 of the covered crimping portion 22 of the terminal fitting 16 and the core wire 14 is placed on the placement portion of the core wire fixing portion 24. 32 so as to be placed on the surface.

かかる状態下で、例えば実開平５−２３３８９号公報に示されるような公知の加締め装置を用いて、被覆電線加締め部３０，３０に加締め加工を施す。これにより、被覆電線加締め部３０，３０を備えた被覆圧着部２２が塑性変形して、被覆電線１２を外周面から包み込むようにして圧着される。   Under such a condition, for example, using a known caulking device as disclosed in Japanese Utility Model Laid-Open No. 5-23389, the covered wire caulking portions 30 and 30 are caulked. As a result, the covered crimp portion 22 including the covered wire crimping portions 30 and 30 is plastically deformed and crimped so as to wrap the covered wire 12 from the outer peripheral surface.

次に、芯線固着部２４の載置部３２に載置された芯線１４を、例えば超音波溶接を用いて芯線固着部２４に溶接固着する。この結果、芯線１４すなわち被覆電線１２が端子金具１６に対して電気的に接続される。   Next, the core wire 14 mounted on the mounting portion 32 of the core wire fixing portion 24 is welded and fixed to the core wire fixing portion 24 using, for example, ultrasonic welding. As a result, the core wire 14, that is, the covered electric wire 12 is electrically connected to the terminal fitting 16.

続いて、弾性リング３８を端子金具１６の接続部２０側から挿通して、連結部３４の切欠部３６の形成部位に配設する。より詳細には、弾性リング３８の挿通孔４０を押し広げるすなわち弾性変形させることにより弾性リング３８を端子金具１６の接続部２０側から挿通して、連結部３４の切欠部３６の形成部位に外嵌する。その際、押し広げられた弾性リング３８の挿通孔４０が弾性復帰されて、弾性リング３８が切欠部３６の形成部位に弾性復元力により密着固定されるようになっている。この結果、連結部３４の全周に亘って弾性リング３８が配設されるのである。また、かかる状態において、弾性リング３８の底面４２は平坦とされている。   Subsequently, the elastic ring 38 is inserted from the connection part 20 side of the terminal fitting 16, and disposed at the formation part of the notch part 36 of the coupling part 34. More specifically, the elastic ring 38 is inserted from the connecting portion 20 side of the terminal fitting 16 by expanding or inserting the insertion hole 40 of the elastic ring 38, and elastically deforming the elastic ring 38. Fit. At this time, the insertion hole 40 of the expanded elastic ring 38 is elastically restored, and the elastic ring 38 is tightly fixed to the formation site of the notch 36 by an elastic restoring force. As a result, the elastic ring 38 is disposed over the entire circumference of the connecting portion 34. In this state, the bottom surface 42 of the elastic ring 38 is flat.

次に、熱収縮チューブ４４を被覆電線１２に沿ってスライドさせ、熱収縮チューブ４４の先端側が弾性リング３８を越えた接続部２０側にくるように、かつ熱収縮チューブ４４の後端側が被覆電線１２の絶縁被覆１８の外周面上にくるように、熱収縮チューブ４４の端部を位置決めする。これにより、弾性リング３８が配設された連結部３４と芯線固着部２４と被覆圧着部２２と被覆電線１２の絶縁被覆１８の周囲を覆うように、熱収縮チューブ４４が被覆電線１２の端末に対して位置決めして装着されている。そして、この状態で、電熱器などの加熱手段を用いて熱収縮チューブ４４を加熱する。なお、熱収縮チューブ４４の内面には接着剤４６が塗布されており、常温では容易に外部へ流れ出さない程度の高粘度を保つと共に、熱収縮チューブ４４が熱収縮を生じさせる温度に加熱されると粘度が低下して流れ出すようになっている。   Next, the heat-shrinkable tube 44 is slid along the covered electric wire 12 so that the front end side of the heat-shrinkable tube 44 comes to the connecting portion 20 side beyond the elastic ring 38 and the rear end side of the heat-shrinkable tube 44 is the covered electric wire. The end portion of the heat shrinkable tube 44 is positioned so as to be on the outer peripheral surface of the 12 insulating coatings 18. As a result, the heat shrinkable tube 44 is attached to the end of the covered wire 12 so as to cover the connecting portion 34 provided with the elastic ring 38, the core wire fixing portion 24, the covered crimp portion 22, and the insulation coating 18 of the covered wire 12. It is positioned and attached to it. In this state, the heat shrinkable tube 44 is heated using heating means such as an electric heater. Note that an adhesive 46 is applied to the inner surface of the heat shrinkable tube 44 so that the heat shrinkable tube 44 is heated to a temperature that causes heat shrinkage while maintaining a high viscosity that does not easily flow out to the outside at room temperature. As a result, the viscosity decreases and the liquid flows out.

この結果、図４に示されているように、熱収縮チューブ４４は熱収縮されて、被覆電線１２の端末を載置部２８，３２とともに締め付ける。これに伴って溶融した接着剤４６は、熱収縮チューブ４４の収縮力によって、連結部３４の先端側および弾性リング３８と、芯線固着部２４と、被覆圧着部２２に亘って広がってそれらと熱収縮チューブ４４の間を密着する。しかも、加熱により溶融した接着剤４６は粘度が低下して流動化していることから、上述した各部材との間に大きな隙間を空けることなく満遍なく埋めることができる。すなわち、上述した各部材に対して接着剤４６を介して液密状態で固着させることができるのである。これにより、図５に示されているように、弾性リング３８の外周面４８の全周に亘って、熱収縮チューブ４４の先端側の開口部５０が密着固定されている。そして、熱収縮チューブ４４の接着剤４６を冷却固化することにより、本実施形態の熱収縮チューブ付電線１０が完成する。   As a result, as shown in FIG. 4, the heat-shrinkable tube 44 is heat-shrinked, and the terminal of the covered electric wire 12 is tightened together with the placement portions 28 and 32. Along with this, the melted adhesive 46 spreads over the distal end side of the connecting portion 34 and the elastic ring 38, the core wire fixing portion 24, and the coated crimping portion 22 by the shrinkage force of the heat shrinkable tube 44, and heats them. The contraction tubes 44 are in close contact with each other. In addition, since the adhesive 46 melted by heating has a reduced viscosity and is fluidized, it can be filled evenly without leaving a large gap between the above-described members. That is, it can be fixed in a liquid-tight state to each member described above via the adhesive 46. As a result, as shown in FIG. 5, the opening 50 on the distal end side of the heat shrinkable tube 44 is tightly fixed over the entire circumference of the outer peripheral surface 48 of the elastic ring 38. And the electric wire 10 with a heat contraction tube of this embodiment is completed by cooling and solidifying the adhesive agent 46 of the heat contraction tube 44. FIG.

このような構造とされた熱収縮チューブ付電線１０によれば、熱収縮チューブ４４の先端側の開口部５０が弾性リング３８の外周面４８の全周に亘って密着固定されている。これにより、従来のように熱収縮チューブ４４の先端側の開口部５０を密着固定領域（従来は連結部３４の外周面）に密着固定する場合に比べて、熱収縮チューブ４４の縮径方向（図２中、左右方向）における熱収縮チューブ４４の先端側の開口部５０と密着固定領域（本実施形態では弾性リング３８の外周面４８）との間の離隔距離（段差）を大幅に低減することができる。すなわち、図２に示されているように、かかる段差を、従来の段差：Ｌ２から本実施形態の段差：Ｌ１へと大幅に低減できるのである。それゆえ、図４，５に示されているように、熱収縮チューブ４４の先端側の開口部５０を弾性リング３８の外周面４８に対して安定して密着固定することができるのである。これにより、従来のように芯線１４端部と連結部３４間の大きな段差：Ｌ２に起因して熱収縮チューブ４４と端子金具１６の間に隙間が生じる不具合を改善でき、防食性を確保することができる。   According to the heat-shrinkable tube-equipped electric wire 10 having such a structure, the opening 50 on the distal end side of the heat-shrinkable tube 44 is tightly fixed over the entire circumference of the outer peripheral surface 48 of the elastic ring 38. Thereby, compared with the case where the opening part 50 of the front end side of the heat-shrinkable tube 44 is tightly fixed to the contact | adherence fixation area | region (conventionally the outer peripheral surface of the connection part 34) conventionally, the diameter reduction direction ( The separation distance (step) between the opening 50 on the distal end side of the heat-shrinkable tube 44 and the tightly fixing region (in this embodiment, the outer peripheral surface 48 of the elastic ring 38) in the left-right direction in FIG. 2 is greatly reduced. be able to. That is, as shown in FIG. 2, this step can be greatly reduced from the conventional step: L2 to the step: L1 of the present embodiment. Therefore, as shown in FIGS. 4 and 5, the opening 50 on the distal end side of the heat shrinkable tube 44 can be stably and firmly fixed to the outer peripheral surface 48 of the elastic ring 38. Thereby, it is possible to improve the problem that a gap is generated between the heat-shrinkable tube 44 and the terminal fitting 16 due to the large step difference L2 between the end portion of the core wire 14 and the connecting portion 34 as in the prior art, and to ensure corrosion resistance. Can do.

また、連結部３４の切欠部３６の形成部位には、弾性リング３８が弾性復帰されて弾性復元力により密着固定されることにより、弾性リング３８が連結部３４の全周に亘って配設されている。このように、弾性リング３８と連結部３４の間においても、連結部３４の全周に亘って弾性リング３８が密着固定されている。すなわち、弾性リング３８の弾性復元力を巧く利用して、寸法公差などを吸収しつつ弾性リング３８と連結部３４の間の隙間の発生を防止して、安定した防食性を確保することができるのである。   The elastic ring 38 is disposed over the entire circumference of the connecting portion 34 by elastically returning the elastic ring 38 to the site where the cutout portion 36 of the connecting portion 34 is formed, and being firmly fixed by an elastic restoring force. ing. As described above, the elastic ring 38 is tightly fixed over the entire circumference of the connecting portion 34 also between the elastic ring 38 and the connecting portion 34. That is, the elastic restoring force of the elastic ring 38 can be skillfully used to prevent the formation of a gap between the elastic ring 38 and the connecting portion 34 while absorbing dimensional tolerances, thereby ensuring stable corrosion resistance. It can be done.

しかも、弾性リング３８が弾力性を有していることから、熱収縮チューブ４４の先端側の開口部５０と弾性リング３８の間および弾性リング３８と連結部３４の間を一層有利に隙間なく密着して覆うことが可能となる。また、熱収縮チューブ４４が熱収縮して弾性リング３８の外周面４８に密着固定される際には、熱収縮チューブ４４の収縮力により弾性リング３８が圧縮されている。これにより、高温の使用環境下で熱収縮チューブ４４が緩み、内部の接着剤４６が溶解した場合でも、弾性リング３８が弾性復帰することにより熱収縮チューブ４４の先端側の開口部５０と弾性リング３８の外周面４８の密着性が保持される。それゆえ、熱収縮チューブ４４内の接着剤４６が外部に流出して、接続部２０などへ悪影響を与える不具合も未然に防止できる。   In addition, since the elastic ring 38 has elasticity, the opening 50 on the distal end side of the heat shrinkable tube 44 and the elastic ring 38 and between the elastic ring 38 and the connecting portion 34 are more advantageously adhered without gaps. And can be covered. Further, when the heat-shrinkable tube 44 is heat-shrinked and tightly fixed to the outer peripheral surface 48 of the elastic ring 38, the elastic ring 38 is compressed by the contraction force of the heat-shrinkable tube 44. As a result, even when the heat shrinkable tube 44 is loosened and the internal adhesive 46 is dissolved under a high temperature use environment, the elastic ring 38 is elastically restored, whereby the opening 50 and the elastic ring on the distal end side of the heat shrinkable tube 44 are restored. The adhesion of the outer peripheral surface 48 of 38 is maintained. Therefore, it is possible to prevent a problem that the adhesive 46 in the heat shrinkable tube 44 flows out to the outside and adversely affects the connection portion 20 or the like.

加えて、弾性リング３８の連結部３４への位置決め固定は、従来のように複雑な特定構造の端子金具を必要とせず、端子金具１６の連結部３４に切欠部３６を設けるという簡単な構造で実現できる。また、弾性リング３８を端子金具１６の連結部３４に取付ける際には、切欠部３６を目印にして容易に取付けることができる。しかも、かかる切欠部３６は、連結部３４を切り欠くことで形成できることから、材料費が増加するおそれもない。さらに、切欠部３６が連結部３４の幅方向両側の対向する位置に設けられていることから、弾性リング３８を連結部３４の周囲に均等な状態でより一層安定して位置決め固定することが可能となり、熱収縮チューブ付電線１０の製品ばらつきを低減することが可能となる。   In addition, the positioning and fixing of the elastic ring 38 to the connecting portion 34 does not require a complicated specific structure of the terminal fitting as in the prior art, and has a simple structure in which the notched portion 36 is provided in the connecting portion 34 of the terminal fitting 16. realizable. Further, when attaching the elastic ring 38 to the connecting portion 34 of the terminal fitting 16, it can be easily attached with the notch 36 as a mark. In addition, since the cutout portion 36 can be formed by cutting out the connecting portion 34, there is no possibility that the material cost increases. Furthermore, since the notches 36 are provided at opposite positions on both sides of the connecting portion 34 in the width direction, the elastic ring 38 can be positioned and fixed more stably around the connecting portion 34 in an even state. Thus, it is possible to reduce the product variation of the heat shrinkable tube-attached electric wire 10.

また、弾性リング３８の底面４２が平坦とされていることから、例えば端子金具１６の接続部２０をボルト締結する場合には、弾性リング３８の底面４２が近隣部材と干渉してボルト締結が安定してできないという問題を解消することが可能となっている。   Further, since the bottom surface 42 of the elastic ring 38 is flat, for example, when the connection portion 20 of the terminal fitting 16 is bolted, the bottom surface 42 of the elastic ring 38 interferes with neighboring members and the bolt fastening is stable. It is possible to solve the problem that cannot be done.

以上、本発明の実施形態について説明してきたが、かかる実施形態における具体的な記載によって、本発明は、何等限定されるものでない。例えば、本実施形態では、切欠部３６は連結部３４の幅方向の両側の対向する位置に設けられていたが、切欠部３６は連結部３４の幅方向の片側のみに形成されていてもよい。また、本実施形態では、芯線１４は芯線固着部２４に溶接されていたが、圧着などの公知の手法を用いて芯線１４を芯線固着部２４に固着するようにしてもよい。   As mentioned above, although embodiment of this invention has been described, this invention is not limited at all by the specific description in this embodiment. For example, in the present embodiment, the notches 36 are provided at opposite positions on both sides of the connecting portion 34 in the width direction, but the notches 36 may be formed only on one side of the connecting portion 34 in the width direction. . In the present embodiment, the core wire 14 is welded to the core wire fixing portion 24. However, the core wire 14 may be fixed to the core wire fixing portion 24 using a known method such as crimping.

さらに、本実施形態では、図３に示されているように、弾性リング３８は略矩形平板状とされていたが、弾性リング３８の形状は、熱収縮チューブ４４の先端側の開口部５０を安定して密着固定することができるようなものであれば、任意の形状が採用可能である。例えば、図６に示されているように、弾性リング５２は略蒲鉾平板状すなわち上面５４が山型とされていてもよい。これにより、弾性リング５２の上面５４の形状を熱収縮チューブ４４の先端側の開口部５０の形状（円筒形状）と沿うようにすることができることから、径方向内方に熱収縮する熱収縮チューブ４４の先端側の開口部５０と弾性リング５２の上面５４の間に隙間が発生することを一層有利に防止することが可能になる。   Furthermore, in this embodiment, as shown in FIG. 3, the elastic ring 38 has a substantially rectangular flat plate shape, but the shape of the elastic ring 38 is such that the opening 50 on the distal end side of the heat shrinkable tube 44 is formed. Any shape can be adopted as long as it can be stably tightly fixed. For example, as shown in FIG. 6, the elastic ring 52 may have a substantially flat plate shape, that is, the upper surface 54 may have a mountain shape. Thereby, since the shape of the upper surface 54 of the elastic ring 52 can be made to follow the shape (cylindrical shape) of the opening part 50 of the front-end | tip side of the heat contraction tube 44, the heat contraction tube which heat-shrinks radially inward. It is possible to more advantageously prevent a gap from being generated between the opening 50 on the distal end side of the 44 and the upper surface 54 of the elastic ring 52.

加えて、例示の実施形態では、連結部３４に切欠部３６を設けて、かかる切欠部３６の形成部位に弾性リング３８を外装固定するようにしていたが、切欠部３６は必ずしも設ける必要はない。すなわち、切欠部３６を設けない既存の端子金具に対して弾性リング３８の弾性復元力を利用して連結部３４に位置決め固定するようにしてもよい。   In addition, in the illustrated embodiment, the notch portion 36 is provided in the connecting portion 34 and the elastic ring 38 is externally fixed to the site where the notch portion 36 is formed. However, the notch portion 36 is not necessarily provided. . In other words, the existing terminal fitting not provided with the notch 36 may be positioned and fixed to the connecting portion 34 using the elastic restoring force of the elastic ring 38.
