Description

本発明は、例えば自動車用ワイヤーハーネスのコネクターに挿入される端子に接続される端末絶縁剥離電線、及び、電線接続構造体に関する。   The present invention relates to a terminal insulated peeled electric wire connected to a terminal inserted into a connector of, for example, an automobile wire harness, and an electric wire connection structure.
従来、自動車の車内配線では、多くの電気配線を必要とするため、複数の電線を束にして集合部品としたワイヤーハーネスが用いられている。このように自動車等に使用されるワイヤーハーネスでは、多芯コネクターに電線が接続された端子としての電線接続構造体が挿入されて、電気接続が確保されている。電線接続構造体には、端子のワイヤーバレルと呼ばれるU字型の電線接続部分に被覆が剥離された電線が圧着と呼ばれる工法でかしめられている。この種の電線接続構造体では、被覆を剥離した電線の表面が露出しているため、雨水等に晒されて腐食が発生しやすいという問題があった。このため、電線の腐食を防止するために、端子に電線を圧着した後に、電線の露出領域及びその近傍領域の全外周を樹脂材等の絶縁被覆部材によってモールド成形する技術が提案されている(例えば、特許文献1参照)。   2. Description of the Related Art Conventionally, in-vehicle wiring of an automobile requires a lot of electric wiring, and therefore, a wire harness that is a collective part made by bundling a plurality of electric wires is used. Thus, in the wire harness used for a motor vehicle etc., the electric wire connection structure as a terminal with which the electric wire was connected to the multi-core connector is inserted, and the electrical connection is ensured. In the electric wire connection structure, an electric wire having a coating peeled off at a U-shaped electric wire connection portion called a wire barrel of a terminal is caulked by a method called crimping. In this type of wire connection structure, the surface of the wire from which the coating has been peeled is exposed, so that there is a problem that corrosion is likely to occur due to exposure to rainwater or the like. For this reason, in order to prevent the corrosion of the electric wire, after the electric wire is crimped to the terminal, a technique for molding the entire outer periphery of the exposed region of the electric wire and the vicinity thereof with an insulating coating member such as a resin material has been proposed ( For example, see Patent Document 1).
特開2011−222243号公報JP 2011-222243 A
しかしながら、特許文献1に記載の技術では、モールド成形は圧着後に個々の圧着部に対して樹脂をモールドする作業を要するため、作業が煩雑になるとともに、ワイヤーハーネスの製造の工程が大きく増す等の課題があった。さらに、モールド成形によって、圧着部が肥大してしまい、各端子が装着されるコネクターハウジングのサイズを上げる必要が生じ、コネクターが大型化してしまうこととなり、ワイヤーハーネス全体を高密小型に成形することができなかった。
そのため、管状の電線接続部と嵌合部とを含む管端子に電線を圧着結合した電線接続構造体が検討されているが、管端子の電線挿入口に端末の絶縁被覆が剥離された電線を挿入する必要があり、電線の管端子への挿入性が悪かった。
本発明は、上述した従来の技術が有する課題を解消し、管端子への電線の挿入性を向上することができる端末絶縁剥離電線、及び、電線接続構造体を提供することを目的とする。
However, in the technique described in Patent Document 1, since molding requires a process of molding a resin on each crimped part after crimping, the process becomes complicated and the manufacturing process of the wire harness greatly increases. There was a problem. In addition, the crimping part is enlarged by molding, and it is necessary to increase the size of the connector housing to which each terminal is mounted, which increases the size of the connector, and the entire wire harness can be molded in a high density and small size. could not.
Therefore, an electric wire connection structure in which an electric wire is crimped and bonded to a tube terminal including a tubular electric wire connection portion and a fitting portion has been studied, but an electric wire having a terminal insulation coating peeled off at an electric wire insertion port of the tube terminal. It was necessary to insert, and the insertability of the wire into the tube terminal was bad.
An object of this invention is to provide the terminal insulation peeling electric wire which can eliminate the subject which the prior art mentioned above has, and can improve the insertion property of the electric wire to a tube terminal, and an electric wire connection structure.

図1は、本発明を適用した実施形態にかかる電線接続構造体10を示す斜視図であり、図2は、電線接続構造体10の長手方向断面を示した断面図である。
電線接続構造体10は、図1に示すように、管端子11と、この管端子11に圧着結合される電線13とを備える。管端子11は、雌型端子の嵌合部20と電線接続部30とを有し、これらの橋渡しとしてトランジション部40を有する。管端子11は、導電性と強度を確保するために基本的に金属材料(本実施形態では、銅または銅合金)の基材で製造されている。なお、管端子11の基材は、銅または銅合金に限るものではなく、アルミニウムや鋼、またはこれらを主成分とする合金等を用いることもできる。
また、管端子11は、端子としての種々の特性を担保するために、例えば管端子11の一部あるいは全部にスズ、ニッケル、銀めっきまたは金等のめっき処理が施されていても良い。また、めっきのみならず、スズ等のリフロー処理を施しても良い。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an electric wire connection structure 10 according to an embodiment to which the present invention is applied, and FIG. 2 is a cross-sectional view showing a longitudinal section of the electric wire connection structure 10.
As shown in FIG. 1, the electric wire connection structure 10 includes a tube terminal 11 and an electric wire 13 that is pressure-bonded to the tube terminal 11. The tube terminal 11 has a female terminal fitting portion 20 and an electric wire connection portion 30, and has a transition portion 40 as a bridge between them. The tube terminal 11 is basically made of a base material made of a metal material (copper or copper alloy in this embodiment) in order to ensure conductivity and strength. In addition, the base material of the tube terminal 11 is not limited to copper or a copper alloy, and aluminum, steel, an alloy containing these as a main component, or the like can also be used.
Moreover, in order to ensure various characteristics as the terminal, the tube terminal 11 may be subjected to, for example, a plating process such as tin, nickel, silver plating, or gold on part or all of the tube terminal 11. Further, not only plating but also reflow treatment of tin or the like may be performed.
電線13は、図2に示すように、例えば、アルミニウムまたはアルミニウム合金性のアルミニウム素線14aを束ねたアルミニウム芯線14を、絶縁樹脂(例えば、ポリ塩化ビニル)で構成する導体絶縁層(電線被覆)15で被覆して構成される。アルミニウム芯線14は、所定の断面積となるように、アルミニウム素線14aを撚って構成しているが、この形態に限定されるものではなく単線で構成しても良い。
なお、芯線を構成する金属材料は、高い導電性を有する金属であればよく、アルミニウムまたはアルミニウム合金の替わりに、銅または銅金属を用いても良い。
As shown in FIG. 2, the electric wire 13 is, for example, a conductor insulating layer (electric wire covering) in which an aluminum core wire 14 in which aluminum or aluminum alloy-like aluminum wires 14a are bundled is made of an insulating resin (for example, polyvinyl chloride). 15 is configured to be covered. The aluminum core wire 14 is formed by twisting the aluminum wire 14a so as to have a predetermined cross-sectional area. However, the aluminum core wire 14 is not limited to this form and may be formed by a single wire.
In addition, the metal material which comprises a core wire should just be a metal which has high electroconductivity, and it may use copper or a copper metal instead of aluminum or an aluminum alloy.
管端子11の嵌合部20は、例えば雄型端子等の挿入タブの挿入を許容する雌型端子の嵌合部である。本発明において、この嵌合部の細部の形状は特に限定されない。すなわち、管端子11は、少なくともトランジション部40を介して電線接続部30を備えていれば良く、例えば嵌合部を有さなくても良いし、例えば嵌合部が雄型端子の挿入タブであっても良い。また、電線接続部30に他の形態に係る端子端部が接続された形状であっても良い。本明細書では、本発明の管端子11を説明するために便宜的に雌型ボックスを備えた例を示している。   The fitting portion 20 of the tube terminal 11 is a fitting portion of a female terminal that allows insertion of an insertion tab such as a male terminal. In the present invention, the shape of the details of the fitting portion is not particularly limited. That is, the tube terminal 11 only needs to include the electric wire connection portion 30 through at least the transition portion 40, and for example, the fitting portion may not have a fitting portion. For example, the fitting portion may be an insertion tab of a male terminal. There may be. Moreover, the shape in which the terminal end part which concerns on another form to the electric wire connection part 30 was connected may be sufficient. In this specification, in order to explain the tube terminal 11 of the present invention, an example in which a female box is provided for convenience is shown.
電線接続部30は、管端子11と電線13とを圧着結合する部位である。電線接続部30の一端は、電線13を挿入することができる電線挿入口31を有し、他端(先端)32はトランジション部40に接続されている。電線接続部30のトランジション部40側の先端32は、溶接等によって封止されており、トランジション部40側から水分等が浸入しないように形成されている。
管端子11の金属基材(銅または銅合金)とアルミニウム芯線14との接合部に水分が付着すると、両金属の起電力(イオン化傾向)の差からアルミニウム芯線14が腐食する。また、管端子11とアルミニウム芯線14とがアルミニウム同士であっても微妙な合金組成の違いによって、それらの接合部は腐食しやすい。
The electric wire connection part 30 is a part for crimping and joining the tube terminal 11 and the electric wire 13. One end of the wire connecting portion 30 has a wire insertion port 31 into which the wire 13 can be inserted, and the other end (tip) 32 is connected to the transition portion 40. The tip 32 on the transition part 40 side of the wire connection part 30 is sealed by welding or the like, and is formed so that moisture or the like does not enter from the transition part 40 side.
When moisture adheres to the joint between the metal base (copper or copper alloy) of the tube terminal 11 and the aluminum core wire 14, the aluminum core wire 14 corrodes due to the difference in electromotive force (ionization tendency) between the two metals. Further, even if the tube terminal 11 and the aluminum core wire 14 are made of aluminum, their joints are easily corroded due to a subtle difference in alloy composition.
本構成では、電線接続部30は、有底の管状に形成されることにより、外部より水分等の浸入が抑制され、管端子11と電線13との接合部の腐食を抑えることができる。なお、電線接続部30は、管状であれば腐食に対して一定の効果を得られるため、必ずしも長手方向に対して円筒である必要はなく、場合によっては楕円や矩形の管であっても良い。また、径が一定である必要はなく、長手方向で半径が変化していても良い。   In this configuration, the wire connection portion 30 is formed in a bottomed tubular shape, so that ingress of moisture and the like is suppressed from the outside, and corrosion of the joint portion between the tube terminal 11 and the wire 13 can be suppressed. In addition, since the electric wire connection part 30 can acquire a fixed effect with respect to corrosion if it is tubular, it does not necessarily need to be a cylinder with respect to the longitudinal direction, and may be an elliptical or rectangular tube depending on the case. . Further, the diameter does not need to be constant, and the radius may change in the longitudinal direction.
電線接続部30では、電線接続部30をかしめて、電線接続部30を構成する金属基材と電線13とを圧着結合することにより、同時に電気的な接合を確保する。このように、電線接続部30では、かしめ接合により、電線接続部30の基材や電線(芯線)を塑性変形させて結合する。従って、電線接続部30は、かしめ接合をすることができるように肉厚を設計する必要があるが、人力加工や機械加工等で接合を自由に行うことができるので、特に限定されるものではない。   In the electric wire connection part 30, the electric connection is ensured simultaneously by crimping the electric wire connection part 30 and crimping | bonding the metal base material and electric wire 13 which comprise the electric wire connection part 30. FIG. Thus, in the electric wire connection part 30, the base material and electric wire (core wire) of the electric wire connection part 30 are plastically deformed and couple | bonded by caulking joining. Therefore, it is necessary to design the thickness of the electric wire connecting portion 30 so that it can be caulked and joined, but since it can be joined freely by human processing or machining, it is not particularly limited. Absent.
電線接続部30と電線13とを圧着する際には、アンビル及びクリンパ(不図示)等の治具を用いて強圧縮することで塑性変形させる。なお、電線接続部30では、アルミニウム芯線14を強圧縮して導通を維持する機能と、導体絶縁層15を圧縮して電線接続部30の内周面と電線13の外周面との間のシール性を維持する機能とが要求される。電線接続部30と電線13とを圧着させる際には、アンビル上にセットした電線接続部30に、上方からクリンパを下降させ、圧力を加えて、かしめる(圧着する)工法を取ることができる。なお、電線13は、電線接続部30に挿入された際に、導体絶縁層15の外周が電線接続部30の内周に密接する径寸法に形成され、電線接続部30と電線13との間のシール性が維持される構成であっても良い。   When the wire connecting portion 30 and the wire 13 are crimped, they are plastically deformed by strong compression using a jig such as an anvil and a crimper (not shown). In addition, in the electric wire connection part 30, the function of maintaining the continuity by strongly compressing the aluminum core wire 14 and the seal between the inner peripheral surface of the electric wire connection part 30 and the outer peripheral surface of the electric wire 13 by compressing the conductor insulating layer 15 And a function to maintain the sex. When crimping the wire connection portion 30 and the wire 13, it is possible to take a construction method in which the crimper is lowered from above and crimped (crimped) by applying pressure to the wire connection portion 30 set on the anvil. . In addition, when the electric wire 13 is inserted in the electric wire connection part 30, the outer periphery of the conductor insulating layer 15 is formed in the diameter dimension closely_contact | adhered to the inner periphery of the electric wire connection part 30, and between the electric wire connection part 30 and the electric wire 13 is formed. The structure in which the sealing property is maintained may be used.
なお、図2は、電線接続部30を嵌合部20と一体に銅または銅合金からなる条材(条)から平面展開した形状に打ち抜き、曲げ加工によって形成した管端子11を有する電線接続構造体10を示す図である。また、この図2に示した電線接続構造体10は、電線接続部30が、プレス断面を上面側で突合せ溶接して管状に形成されている構成である。
電線接続構造体10は、図示は省略するが、電線接続部30が、プレス断面を下面側で突合せ溶接して管状に形成されている構成であっても良い。また、電線接続構造体10は、電線接続部30と嵌合部20とが別体に条材から打ち抜かれ、曲げ加工した電線接続部30と嵌合部20とを溶接して管端子11を形成する構成であっても良い。また、電線接続構造体10は、プレス絞り加工により形成された絞り管の電線接続部30と嵌合部20とを溶接して管端子11を形成する構成であっても良い。
FIG. 2 shows an electric wire connection structure having a tube terminal 11 formed by punching the electric wire connection portion 30 into a shape developed from a strip (copper) made of copper or a copper alloy integrally with the fitting portion 20 and bending. FIG. Moreover, the electric wire connection structure 10 shown in this FIG. 2 is the structure by which the electric wire connection part 30 is formed in the tubular shape by butt-welding a press cross section on the upper surface side.
Although illustration is abbreviate | omitted for the electric wire connection structure 10, the structure by which the electric wire connection part 30 is formed in the tubular shape by butt-welding a press cross section on the lower surface side may be sufficient. Further, in the wire connection structure 10, the wire connection portion 30 and the fitting portion 20 are punched separately from the strip material, and the bent wire connection portion 30 and the fitting portion 20 are welded to connect the tube terminal 11. The structure to form may be sufficient. Further, the wire connection structure 10 may have a configuration in which the tube terminal 11 is formed by welding the wire connection portion 30 and the fitting portion 20 of the drawn tube formed by press drawing.
また、電線接続部30の内壁面には、図3に示すように、電線の周方向に延びるセレーションと呼ばれる電線係止溝39が複数設けられている構成であっても良い。そして、電線13を電線挿入口31から電線接続部30内に挿入する際には、この電線係止溝39により、露出したアルミニウム芯線14表面の酸化被膜が破られる構成であっても良い。
図3(A)、図3(B)、及び、図3(C)は、先端の導体絶縁層15が剥離され、アルミニウム芯線14が剥きだしとなった電線13である端末絶縁剥離電線13A〜13Cをそれぞれ示す図である。電線13は、このように、先端の導体絶縁層15が剥離され、アルミニウム芯線14が剥きだしとなった状態で電線接続部30に挿入される。そのため、露出した導体先端16が外周方向に広がり、電線13の電線接続部30への挿入性が悪かった。そのため、本実施形態では、電線13の露出した導体先端16を先細り形状にすることで、電線13の電線接続部30への挿入性を向上させている。
Further, as shown in FIG. 3, a configuration in which a plurality of wire locking grooves 39 called serrations extending in the circumferential direction of the wire is provided on the inner wall surface of the wire connecting portion 30 may be adopted. And when inserting the electric wire 13 in the electric wire connection part 30 from the electric wire insertion port 31, the structure by which the oxide film of the exposed aluminum core wire 14 surface is broken by this electric wire latching groove 39 may be sufficient.
3 (A), 3 (B), and 3 (C), terminal insulated peeled wires 13A to 13C, which are wires 13 in which the conductor insulating layer 15 at the tip is peeled off and the aluminum core wire 14 is exposed. It is a figure which shows 13C, respectively. Thus, the electric wire 13 is inserted in the electric wire connection part 30 in the state from which the conductor insulating layer 15 of the front-end | tip was peeled and the aluminum core wire 14 was exposed. Therefore, the exposed conductor tip 16 spreads in the outer peripheral direction, and the insertion property of the electric wire 13 into the electric wire connecting portion 30 was poor. Therefore, in this embodiment, the insertion property to the electric wire connection part 30 of the electric wire 13 is improved by making the conductor tip 16 which the electric wire 13 exposed tapered.
図3(A)は、導体先端16Aを先端中心に向かって先細りする先細り形状にした端末絶縁剥離電線13Aを示す図である。端末絶縁剥離電線13Aは、電線先端の導体絶縁層15が適切な長さストリップされ、先端からアルミニウム芯線14Aが露出している。そして、アルミニウム芯線14Aが露出した導体先端16Aは、先端中心に向かって先細りするように切断されている。導体先端16Aは、先端中心が頂点となる円錐形状に切断されていることが望ましい。この構成によれば、端末絶縁剥離電線13Aは、導体先端16Aが先端中心に向かって先細りする先細り形状に切断されているため、電線接続部30への端末絶縁剥離電線13Aの挿入作業を容易にすることができる。   FIG. 3A is a diagram showing a terminal insulated peeled wire 13A having a tapered shape in which the conductor tip 16A is tapered toward the tip center. In the terminal insulated peeled electric wire 13A, the conductor insulating layer 15 at the tip of the wire is stripped to an appropriate length, and the aluminum core wire 14A is exposed from the tip. The conductor tip 16A from which the aluminum core wire 14A is exposed is cut so as to taper toward the tip center. The conductor tip 16A is desirably cut into a conical shape having the tip center as a vertex. According to this configuration, the terminal insulated peeled electric wire 13A is cut into a tapered shape with the conductor tip 16A tapering toward the tip center, so that the terminal insulated peeled wire 13A can be easily inserted into the wire connecting portion 30. can do.
図3(B)は、導体先端16Bを先端下端に向かって先細りする先細り形状にした端末絶縁剥離電線13Bを示す図である。端末絶縁剥離電線13Bは、電線先端の導体絶縁層15が適切な長さストリップされ、アルミニウム芯線14Bが露出した導体先端16Bが先端下端に向かって先細りするように、斜めに切断されている。本実施形態では、電線接続部30は、先端32を底面側に向かって押し潰して内部が封止されているため、導体先端16Bを先端下端に向かって先細りする形状とすることで、端末絶縁剥離電線13Bを電線接続部30の奥まで容易に挿入することができる。この構成によれば、端末絶縁剥離電線13Bは、導体先端16Bが先端下端に向かって先細りする先細り形状に切断されているため、電線接続部30への端末絶縁剥離電線13Bの挿入作業を容易にすることができる。
なお、端末絶縁剥離電線13Bは、導体先端16Bが斜めに切断されて先細りする形状に形成されている構成であればよく、下端に向かって斜めに切断されている構成に限られるものではない。
FIG. 3B is a diagram showing a terminal insulated peeled wire 13B having a tapered shape in which the conductor tip 16B is tapered toward the lower end of the tip. The terminal-insulated peeled electric wire 13B is cut obliquely so that the conductor insulating layer 15 at the tip of the wire is stripped to an appropriate length and the conductor tip 16B from which the aluminum core wire 14B is exposed tapers toward the lower end of the tip. In the present embodiment, since the wire connection portion 30 is crushed toward the bottom surface side by crushing the tip 32, the inside is sealed, so that the conductor tip 16B is tapered toward the tip bottom end, thereby terminal insulation.

The terminal insulating peeled electric wire 13C is cut so that the conductor insulating layer 15 at the tip of the wire is stripped to an appropriate length, and the conductor tip 16C from which the aluminum core wire 14C is exposed tapers in a hemispherical convex shape toward the tip center. According to this configuration, the terminal insulated peeled wire 13C is cut into a tapered shape in which the conductor tip 16C tapers in a hemispherical convex shape toward the tip center, and therefore the terminal insulated peeled wire 13A is inserted into the wire connecting portion 30. Work can be facilitated.
As shown in FIGS. 3 (A), 3 (B), and 3 (C), the wire 13 is stripped of the conductor insulating layer 15 at the tip of the wire, and the exposed conductor tips 16A to 16C are removed.

図4は、電線13の一部を圧縮した後に導体絶縁層15を適切な長さストリップして、導体先端16Dが先細りする端末絶縁剥離電線13Cを製造する製造工程の例を示す図である。図4(B)に示すように、電線13は、長さ方向の任意の一部を、圧縮部分の先端が先端中心に向かって先細りするように、導体絶縁層15上から周方向に圧縮される。これにより、電線13は、圧縮された部分の導体絶縁層15及び導体絶縁層15内部のアルミニウム芯線14Dが圧縮され塑性変形する。   FIG. 4 is a diagram illustrating an example of a manufacturing process for manufacturing the terminal insulated peeled electric wire 13C in which the conductor insulating layer 15 is stripped to an appropriate length after a part of the electric wire 13 is compressed and the conductor tip 16D is tapered. As shown in FIG. 4B, the electric wire 13 is compressed in the circumferential direction from above the conductor insulating layer 15 so that an arbitrary part in the length direction is tapered toward the center of the tip. The As a result, in the electric wire 13, the compressed portion of the conductor insulating layer 15 and the aluminum core wire 14D inside the conductor insulating layer 15 are compressed and plastically deformed.

And the conductor insulating layer 15 of the front-end | tip part of the cut | disconnected electric wire 13 is stripped from the outer side of a compression part. Thereby, the terminal insulation peeling electric wire 13D which the conductor front-end | tip 16D formed in the taper shape by compression is exposed is manufactured. In the terminal insulated peeled wire 13D, since the conductor insulating layer 15 is stripped from the outside of the compressed portion, the conductor tip 16D is compressed and tapered, and the conductor insulating layer 15 is not compressed.

Thereby, the terminal insulation peeling electric wire 13E which the conductor tip 16E compressed and formed in the taper shape exposed is manufactured. Moreover, in the terminal insulation peeling electric wire 13E, since the conductor insulating layer 15 is stripped from the inner side of the compression portion, the conductor tip 16E and the tip 15A of the conductor insulating layer 15 are compressed and tapered.
