Description

本発明は、一本の導体芯線が絶縁体に被覆された単芯線を相手側の接続箇所に直接的に接続するための接続構造に関する。   The present invention relates to a connection structure for directly connecting a single-core wire in which a single conductor core wire is covered with an insulator to a connection point on the other side.

従来から、単芯線と相手側の接続箇所とを接続するための種々の接続構造が提案されている(例えば、特許文献1〜3を参照)。例えば、従来の接続構造の一つでは、単芯線の端部において露出した導体芯線と、相手側の多芯電線の端部において露出した多数の素線を溶着して束ねた接続箇所と、を超音波接合法により溶着させるようになっている(例えば、特許文献1を参照)。   Conventionally, various connection structures for connecting a single-core wire and a connection point on the other side have been proposed (see, for example, Patent Documents 1 to 3). For example, in one of the conventional connection structures, a conductor core wire exposed at the end of a single-core wire and a connection point formed by welding and bundling a large number of exposed strands at the end of the multicore wire on the other side Welding is performed by ultrasonic bonding (see, for example, Patent Document 1).

特開2016−058137号公報JP, 2016-058137, A 特開2017−027687号公報JP, 2017-027687, A 特開2011−113928号公報JP, 2011-113928, A

上述した従来の接続構造は、単芯線の導体芯線と相手側の接続箇所とを超音波接合法によって溶着して接続しているため、その溶着が一旦完了すると、接続状態の解除(即ち、溶着した箇所の分離)が困難である。一方、電線同士を容易に着脱可能に接続する手法として、双方の電線の端部にコネクタを取り付け、コネクタ同士を嵌合することが挙げられる。しかし、このようなコネクタ接続の場合、単芯線と相手側の接続箇所との双方にコネクタを付ける分だけ、部品点数が増大することになる。   In the conventional connection structure described above, since the conductor core wire of the single core wire and the connection portion on the other side are welded and connected by ultrasonic bonding, once the welding is completed, the connection state is released (i.e., welding) Separation is difficult. On the other hand, attaching a connector to the end part of both electric wires and fitting connectors as a method of connecting electric wires easily detachably is mentioned. However, in the case of such a connector connection, the number of parts is increased by attaching a connector to both the single-core wire and the other connection point.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、部品点数の増大を避けながら単芯線と相手側の接続箇所とを着脱可能に接続する接続構造、を提供することにある。   The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a connection structure for detachably connecting a single core wire and a connection portion on the other side while avoiding an increase in the number of parts. is there.

以下、図面を参照しながら、本発明の実施形態に係る単芯線の接続構造1について説明する。
Embodiment
Hereinafter, the single core wire connection structure 1 according to the embodiment of the present invention will be described with reference to the drawings.

図1及び図2に示すように、この接続構造1は、単芯線10と相手側単芯線20とを接続するための接続構造である。以下、単芯線10及び相手側単芯線20の構造について、順に説明する。   As shown in FIGS. 1 and 2, the connection structure 1 is a connection structure for connecting the single-core wire 10 and the other-side single-core wire 20. Hereinafter, the structure of the single cored wire 10 and the mating single cored wire 20 will be described in order.

先ず、単芯線10について説明する。図1(a)及び図2(a)〜(c)に示すように、単芯線10は、一本の断面円形の導体芯線11と、導体芯線11の外周を覆う樹脂製の絶縁被覆12と、を備える。本例では、絶縁被覆12は、導体芯線11の外周面の全体を覆っている。導体芯線11は、導電性の金属から構成され、好ましくは、軽量化及び低コスト化のため、アルミニウム又はアルミニウム合金から構成される。   First, the single core wire 10 will be described. As shown in FIGS. 1 (a) and 2 (a) to 2 (c), the single-core wire 10 comprises a single conductor core wire 11 having a circular cross section and a resin insulation coating 12 covering the outer periphery of the conductor core wire 11. And. In the present example, the insulating coating 12 covers the entire outer peripheral surface of the conductor core wire 11. The conductor core wire 11 is made of a conductive metal, and preferably made of aluminum or an aluminum alloy for weight reduction and cost reduction.

導体芯線11の端面11a(平面)からは、端面11aに近い側から順に小径部13、大径部14、及び、タブ部15からなる段付き円柱状の凹凸形状部16が、絶縁被覆12から露出するように、軸線方向先端側へ向けて導体芯線11と同軸的に一体で突出している。本例では、大径部14の外径が導体芯線11の外径より小さく、小径部13の外径が大径部14の外径より小さく、タブ部15の外径が小径部13の外径より小さい。   From the end face 11 a (plane) of the conductor core 11, the stepped cylindrical uneven portion 16 including the small diameter portion 13, the large diameter portion 14, and the tab portion 15 in this order from the side close to the end surface 11 a It projects integrally integrally with the conductor core wire 11 toward the axial direction tip side so as to be exposed. In this example, the outer diameter of the large diameter portion 14 is smaller than the outer diameter of the conductor core wire 11, the outer diameter of the small diameter portion 13 is smaller than the outer diameter of the large diameter portion 14, and the outer diameter of the tab portion 15 is outer diameter of the small diameter portion 13. Less than diameter.

小径部13と大径部14との境界の段部(大径部14の基端側側面)は、軸線方向に垂直な垂直面14aで構成され、大径部14とタブ部15との境界の段部(大径部14の先端側側面)は、先細り状(円錐側面状)に傾斜するテーパ面14bで構成されている。更に、導体芯線11の端面11aと、小径部13と、大径部14の垂直面14aとで、環状凹部17が形成されている。タブ部15の軸線方向の途中部分には、同軸的に径方向に曲面状に膨出する接触部18が形成されている。接触部18の最大外径は、小径部13の外径より若干小さい寸法に設定されている。   The stepped portion of the boundary between the small diameter portion 13 and the large diameter portion 14 (the proximal end side surface of the large diameter portion 14) is constituted by a vertical surface 14a perpendicular to the axial direction, and the boundary between the large diameter portion 14 and the tab portion 15 The step portion (the end side surface of the large diameter portion 14) is formed of a tapered surface 14b which is inclined in a tapered shape (conical side surface shape). Furthermore, an annular recess 17 is formed by the end face 11 a of the conductor core wire 11, the small diameter portion 13, and the vertical surface 14 a of the large diameter portion 14. At an intermediate portion in the axial direction of the tab portion 15, a contact portion 18 that bulges in a curved shape in the radial direction is formed coaxially. The maximum outer diameter of the contact portion 18 is set to a size slightly smaller than the outer diameter of the small diameter portion 13.

凹凸形状部16は、導体芯線11の端部に対する切削加工によっても形成され得るが、導体芯線11の端部に対するプレス加工によって形成されることが好ましい。即ち、凹凸形状部16は、単芯線10の端面から凹凸形状部16の軸線方向長さ分だけ絶縁被覆12を除去して得られる導体芯線11の露出部分(円柱状部分)に対してプレス加工を施すことで形成され得る。   The concavo-convex shaped portion 16 may be formed by cutting the end of the conductor core 11 but is preferably formed by pressing the end of the conductor 11. That is, the concavo-convex shaped part 16 is pressed on the exposed part (cylindrical part) of the conductor core 11 obtained by removing the insulation coating 12 from the end face of the single core wire 10 by the axial length of the concavo-convex part 16 It can be formed by applying

次いで、相手側単芯線20について説明する。図1(b)及び図2に示すように、相手側単芯線20も、単芯線10と同様、一本の断面円形の導体芯線21と、導体芯線21の外周を覆う樹脂製の絶縁被覆22と、を備える。導体芯線21も、導体芯線11と同様、導電性の金属から構成され、好ましくは、軽量化及び低コスト化のため、アルミニウム又はアルミニウム合金から構成される。   Next, the mating single core wire 20 will be described. As shown in FIG. 1 (b) and FIG. 2, the mating single core wire 20 also has a single conductor core wire 21 having a circular cross section and the resin insulation coating 22 covering the outer periphery of the conductor core wire 21 as the single core wire 10. And. The conductor core wire 21 is also made of a conductive metal like the conductor core wire 11, and preferably made of aluminum or an aluminum alloy for weight reduction and cost reduction.

導体芯線21の端面21aには、タブ部15を挿入するための細長円柱状の穴部23が同軸的に形成されている。更に、導体芯線21の端面21aには、直径方向両端部に対応する位置から、一対のアーム部24が、絶縁被覆22から露出するように、径方向に対向しながら軸線方向先端側へ向けて突出している。一対のアーム部24で挟まれた空間は、大径部14を保持するための保持空間26を構成している。片持ち梁状のアーム部24は、径方向に弾性可能となっている。   An elongated cylindrical hole 23 for inserting the tab 15 is coaxially formed in the end face 21 a of the conductor core wire 21. Furthermore, on the end face 21 a of the conductor core wire 21, from the position corresponding to both end portions in the diameter direction, the pair of arm portions 24 face the tip end side in the axial direction while opposing in the radial direction It protrudes. A space sandwiched by the pair of arm portions 24 constitutes a holding space 26 for holding the large diameter portion 14. The cantilevered arm 24 is resilient in the radial direction.

一対のアーム部24の先端部には、互いに近付く方向に(径方向内側に)突出する一対の係合部25が形成されている。各係合部25における径方向内側端部の軸線方向先端側の角部には、テーパ面25aが形成されている。ここで、穴部23、一対のアーム部24、及び、一対の係合部25により、相手側単芯線20の接続箇所27が構成されている。   A pair of engaging portions 25 that project in directions (inward in the radial direction) approaching each other are formed at the tip end portions of the pair of arm portions 24. A tapered surface 25 a is formed at the corner on the tip side in the axial direction of the radial inner end of each engaging portion 25. Here, the connection portion 27 of the mating single-core wire 20 is configured by the hole portion 23, the pair of arm portions 24, and the pair of engagement portions 25.

図2(c)から理解できるように、穴部23の内径は、タブ部15の接触部18の最大外径と同等の寸法(該最大外径より若干小さい寸法が好ましい)に設定されている。一対のアーム部24の間隔は、大径部14の外径と同等の寸法に設定されている。一対の係合部25の径方向内側端部同士の間隔は、小径部13の外径と同等の寸法(よって、接触部18の最大外径より若干大きい寸法)に設定されている。換言すれば、相手側単芯線20の接続箇所27は、単芯線10の導体芯線11の凹凸形状部16に対応した形状を有している。   As can be understood from FIG. 2C, the inner diameter of the hole 23 is set to a dimension equal to the maximum outer diameter of the contact portion 18 of the tab portion 15 (a size slightly smaller than the maximum outer diameter is preferable) . The distance between the pair of arm portions 24 is set to the same dimension as the outer diameter of the large diameter portion 14. The distance between the radially inner end portions of the pair of engaging portions 25 is set to a dimension equal to the outer diameter of the small diameter portion 13 (therefore, a dimension slightly larger than the maximum outer diameter of the contact portion 18). In other words, the connection portion 27 of the mating single-core wire 20 has a shape corresponding to the uneven portion 16 of the conductor core 11 of the single-core wire 10.

接続箇所27(穴部23、一対のアーム部24、及び、一対の係合部25)は、導体芯線21の端部に対する切削加工によって形成されることが好ましい。即ち、接続箇所27は、相手側単芯線20の端面からアーム部24の軸線方向長さ分だけ絶縁被覆22を除去して得られる導体芯線21の露出部分(円柱状部分)に対して切削加工を施すことで形成され得る。   The connection portion 27 (the hole portion 23, the pair of arm portions 24, and the pair of engagement portions 25) is preferably formed by cutting the end of the conductor core wire 21. That is, the connection point 27 is cut on the exposed portion (cylindrical portion) of the conductor core wire 21 obtained by removing the insulation coating 22 from the end face of the mating single-core wire 20 by the axial length of the arm portion 24 It can be formed by applying

次いで、図2(a)〜(c)を参照しながら、単芯線10と相手側単芯線20とを接続方法の一例について説明する。先ず、図2(a)に示すように、単芯線10のタブ部15における接触部18より基端側の部分が相手側単芯線20の一対の係合部25間の隙間に位置するように単芯線10及び相手側単芯線20を同軸的に配置する。次いで、この状態から、単芯線10及び相手側単芯線20を軸線方向に相対的に近づけて、タブ部15の先端部を相手側単芯線20の穴部23に挿入する。   Then, an example of the connection method of the single cored wire 10 and the other party single cored wire 20 is demonstrated, referring FIG. 2 (a)-(c). First, as shown in FIG. 2A, the proximal end portion of the tab portion 15 of the single core wire 10 with respect to the contact portion 18 is positioned in the gap between the pair of engagement portions 25 of the mating single core wire 20. The single cored wire 10 and the mating single cored wire 20 are coaxially arranged. Next, from this state, the single core wire 10 and the single core wire 20 on the other side are made relatively close in the axial direction, and the tip of the tab portion 15 is inserted into the hole 23 of the single core wire 20 on the other side.

次いで、単芯線10及び相手側単芯線20を軸線方向に更に近づけて、大径部14のテーパ面14bを一対の係合部25のテーパ面25aに当接させ、この状態にて、単芯線10及び相手側単芯線20を軸線方向に相対的に近づく方向に押圧する。この押圧力により、テーパ面14bが一対のテーパ面25aを径方向外側に押圧する。   Next, the single-core wire 10 and the mating single-core wire 20 are brought closer to the axial direction, and the tapered surface 14b of the large diameter portion 14 is brought into contact with the tapered surfaces 25a of the pair of engaging portions 25. 10 and the mating single core wire 20 are pressed in a direction relatively approaching in the axial direction. By this pressing force, the tapered surfaces 14 b press the pair of tapered surfaces 25 a radially outward.

この結果、一対のアーム部24が径方向外側に弾性変形した状態で大径部14が一対の係合部25間の隙間を通過し、且つ、タブ部15が穴部23に更に深く進入しながら、単芯線10及び相手側単芯線20が軸線方向に相対的に更に近づく。このように、タブ部15が穴部23に更に深く進入していくことで、タブ部15の接触部18が穴部23に進入していく。   As a result, the large diameter portion 14 passes through the gap between the pair of engaging portions 25 in a state where the pair of arm portions 24 is elastically deformed outward in the radial direction, and the tab portion 15 penetrates deeper into the hole 23. However, the single cored wire 10 and the mating single cored wire 20 are relatively closer in the axial direction. Thus, the contact portion 18 of the tab portion 15 enters the hole 23 as the tab portion 15 enters the hole 23 more deeply.

そして、大径部14が一対の係合部25間の隙間を通り越してその全体が保持空間26に進入すると、一対のアーム部24が径方向内側に弾性復帰し、一対の係合部25が環状凹部17に嵌合する。この結果、図2(b)及び図2(c)に示すように、単芯線10及び相手側単芯線20の接続が完了し、単芯線の接続構造1が得られる。   Then, when the large diameter portion 14 passes the gap between the pair of engaging portions 25 and the whole enters the holding space 26, the pair of arm portions 24 elastically return inward in the radial direction, and the pair of engaging portions 25 The annular recess 17 is fitted. As a result, as shown in FIG. 2B and FIG. 2C, the connection of the single-core wire 10 and the mating single-core wire 20 is completed, and the single-core connection structure 1 is obtained.

この接続構造1では、タブ部15の接触部18が穴部23の内壁面に直接的に接触することで、導体芯線11及び導体芯線21(よって、単芯線10及び相手側単芯線20)が電気的に接続され、且つ、一対の係合部25が大径部14の垂直面14aを係止することで、単芯線10及び相手側単芯線20が軸線方向に分離する(相対的に遠ざかる)ことが防止されている。   In this connection structure 1, the conductor core 11 and the conductor core 21 (thereby, the single core wire 10 and the mating single core wire 20) are directly connected by the contact portion 18 of the tab portion 15 directly contacting the inner wall surface of the hole 23. The single core wire 10 and the mating single core wire 20 are separated in the axial direction by being electrically connected and the pair of engaging portions 25 engaging the vertical surface 14 a of the large diameter portion 14 (relatively distant) ) Is prevented.

以上、本発明の実施形態に係る単芯線の接続構造1によれば、単芯線10の導体芯線11そのものが、相手側接続対象である相手側単芯線20の接続箇所27との係合に適した凹凸形状部16を有するようになっている。そして、相手側単芯線20の接続箇所27が有する一対の係合部25と、導体芯線11の凹凸形状部16と、が係合することで、単芯線10と相手側単芯線20の接続箇所27とが直接的に接続されることになる。よって、コネクタ等を介して両者を接続することがないため、部品点数の増大を避けられる。また、導体芯線11と接続箇所27との係合によって両者が接続されるため、両者を溶着等によって接続する場合に比べ、両者の着脱が容易である。   As mentioned above, according to the connection structure 1 of the single core wire which concerns on embodiment of this invention, the conductor core wire 11 of the single core wire 10 itself is suitable for engagement with the connection location 27 of the other party single core wire 20 which is the other party connection object. The uneven portion 16 is provided. Then, the pair of engaging portions 25 of the connection portion 27 of the mating single core wire 20 and the concavo-convex shaped portion 16 of the conductor core wire 11 engage with each other to connect the single core wire 10 and the mating single core wire 20 27 will be directly connected. Therefore, since both are not connected via a connector etc., the increase in a number of parts is avoidable. Moreover, since both are connected by engagement with the conductor core wire 11 and the connection location 27, compared with the case where both are connected by welding etc., attachment or detachment of both is easy.

したがって、本構成の単芯線の接続構造1は、部品点数の増大を避けながら、単芯線10の凹凸形状部16と相手側単芯線20の接続箇所27とを着脱可能に接続できる。   Therefore, the single-core wire connection structure 1 of the present configuration can detachably connect the uneven portion 16 of the single-core wire 10 and the connection portion 27 of the other single-core wire 20 while avoiding an increase in the number of parts.

<Other aspects>
The present invention is not limited to the above embodiments, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the embodiments described above, and appropriate modifications, improvements, etc. are possible. In addition, the material, shape, size, number, arrangement location, and the like of each component in the embodiment described above are arbitrary and not limited as long as the present invention can be achieved.

例えば、上記実施形態では、単芯線10の相手側接続対象として相手側単芯線20が採用されている(図1及び図2を参照)。しかし、図3に示すように、単芯線10の相手側接続対象が電気接続箱30であってもよい。この場合、電気接続箱30の所定の接点(導体部分)に、相手側単芯線20の接続箇所27と同じ構成の接続箇所27(穴部23、一対のアーム部24、及び、一対の係合部25)が設けられ、単芯線10の凹凸形状部16と電気接続箱30の接続箇所27とが着脱可能に接続される。   For example, in the said embodiment, the other party single core wire 20 is employ | adopted as the other party connection object of the single core wire 10 (refer FIG.1 and FIG.2). However, as shown in FIG. 3, the other-side connection target of the single-core wire 10 may be the electric connection box 30. In this case, the connection point 27 (the hole 23, the pair of arm parts 24, and the pair of engagements) having the same configuration as the connection point 27 of the mating single core wire 20 at the predetermined contact (conductor part) of the electrical connection box 30 A portion 25) is provided, and the uneven portion 16 of the single-core wire 10 and the connection portion 27 of the electric connection box 30 are detachably connected.

更に、上記実施形態では、接続箇所27に一対のアーム部24が設けられているが、一対のアーム部24のうち何れか1本のアーム部24のみが設けられていてもよい。これによっても、1本のアーム部24の係合部25が大径部14の垂直面14aを係止することで、単芯線10及び相手側単芯線20が軸線方向に分離する(相対的に遠ざかる)ことを防止する機能が維持され得る。   Furthermore, in the above embodiment, the pair of arm portions 24 is provided at the connection portion 27. However, only one of the arm portions 24 may be provided among the pair of arm portions 24. Also by this, the single core wire 10 and the mating single core wire 20 are separated in the axial direction by the engagement portion 25 of one arm portion 24 engaging the vertical surface 14 a of the large diameter portion 14 (relatively The ability to prevent going away can be maintained.

更に、上記実施形態では、タブ部15が細長円柱状の棒状部分、且つ、穴部23が細長円柱状の穴となっているが、逆に、タブ部15が細長角柱状の棒状部分、且つ、穴部23が細長角柱状の穴であってもよい。この場合、タブ部15が穴部23に挿入されることで、単芯線10及び相手側単芯線20が周方向に相対的に回転することが防止され得る。   Furthermore, in the above embodiment, the tab portion 15 is an elongated cylindrical rod portion and the hole 23 is an elongated cylindrical hole, but conversely, the tab portion 15 is an elongated prismatic rod portion, and The hole 23 may be an elongated prismatic hole. In this case, inserting the tab portion 15 into the hole portion 23 can prevent the single core wire 10 and the mating single core wire 20 from rotating relative to each other in the circumferential direction.
