Description
本発明は端子および該端子の電線接続構造に関し、特に、車両に配索されるアルミニウム電線に接続する端子として好適に用いられるものである。 The present invention relates to a terminal and an electric wire connection structure of the terminal, and is particularly preferably used as a terminal connected to an aluminum electric wire arranged in a vehicle.
従来、電線端末に接続する銅系金属板からなる端子100は、図4に示すように、長さ方向の一側に電線接続部101、他側に電気接触部102を連続して備え、電線接続部101に絶縁被覆バレル103と芯線バレル104を設けている。該端子100に対して、電線200の端末で露出した芯線201を芯線バレル104で加締め圧着し、絶縁被覆層202を絶縁被覆バレル103で加締め圧着している。
Conventionally, as shown in FIG. 4, a
近時、芯線を銅系金属で形成した銅電線に対して、軽量化の観点から芯線をアルミニウム系金属で形成したアルミニウム電線(以下、アルミ電線と称する)が自動車用電線として用いられている。該アルミ電線では芯線のアルミニウム系金属と銅系金属からなる端子とが異種金属であるため、互いに接触する接続部に水分が付着すると腐食が発生しやすい問題がある。 Recently, an aluminum electric wire (hereinafter referred to as an aluminum electric wire) in which a core wire is formed of an aluminum-based metal has been used as an electric wire for an automobile, from the viewpoint of weight reduction, with respect to a copper electric wire having a core wire formed of a copper-based metal. In the aluminum electric wire, since the aluminum metal of the core wire and the terminal made of copper metal are dissimilar metals, there is a problem that corrosion tends to occur when moisture adheres to the connecting portions that are in contact with each other.
前記問題に対して、特開2013−80682号公報で、図5に示すように、端子と芯線との接続部を防水仕様としたアルミ電線圧着用の端子300が提供されている。該端子300は電線接続部に、アルミ電線400の芯線401と絶縁被覆402を連続的に加締め圧着する長尺なバレル303(303a、303b)を基板304の幅方向両側から突設した加締め部305が設けられている。該加締め部305の長さ方向の両端およびバレルの突出端の長さ方向端縁に沿う四角周縁にシール材306(306a、306b、306c、306d)が設けられている。該シール材306はポリアミド系、シリコーン系、ポリウレタン系等の樹脂、エラストマー等から形成されている。
As shown in FIG. 5, JP 2013-80682 A discloses a
前記端子300はバレル303を芯線401および絶縁被覆402に加締め圧着すると、バレル後端のシール材306bが絶縁被覆402の外周面に密着し、シール材306cと306dがバレル303aと303bとの重ね部を囲み、芯線401の先端をシール材306aで囲むことにより、芯線401と端子300との接触部へ浸水を許容する隙間が生じないように封止している。
When the
特許文献1で提供されている端子300は、銅系金属板からなる端子の加締め部305の四辺の周縁に沿って樹脂あるいはエラストマーからなる細帯状のシール材306を接着剤を介して接着し、または接着性を有するシール材306を接着し、あるいは加熱して融着させている。さらに、シール材306が液相材料の場合は、加熱、紫外線照射、2液混合、嫌気、水分反応等により端子に塗布した後に硬化されている。
A
前記のように、金属材からなる端子に樹脂あるいはエラストマーからなる別体のシール材306と付設するために端子を製造する工程で作業工程が増えて作業時間がかかり、生産性が悪く且つコストがかかる問題がある。
さらに、シール材を金属製の端子に接着した場合、接着部が経年劣化してシール材と端子との間に隙間が発生する恐れがある。一方、融着あるいは塗布後に硬化した場合はシール材306の厚さ精度が劣り、均一性がなく、バレルを圧着した状態で絶縁被覆との接触部に隙間が発生する恐れがあり、止水性が十分でない問題がある。
As described above, the number of work steps increases in the process of manufacturing a terminal to attach a separate seal material 306 made of resin or elastomer to a terminal made of a metal material, and the work takes time, resulting in poor productivity and cost. There is such a problem.
Furthermore, when the sealing material is bonded to a metal terminal, the bonded portion may deteriorate over time and a gap may be generated between the sealing material and the terminal. On the other hand, when cured after fusion or application, the thickness accuracy of the sealing material 306 is inferior, there is no uniformity, and there is a risk that a gap will occur at the contact portion with the insulating coating in a state where the barrel is pressure-bonded. There is not enough problem.
本発明は前記問題を解消せんとするもので、電線と端子との接続部への浸水を確実に防止でき、電線の芯線と端子との接触部で水分による腐食が発生するのを確実に防止できる端子および該端子の電線接続構造を提供することを課題としている。 The present invention is intended to solve the above-mentioned problems, and can reliably prevent water from entering the connection portion between the electric wire and the terminal, and can reliably prevent corrosion due to moisture at the contact portion between the core wire and the terminal of the electric wire.

ついで、加締め圧着装置(図示せず)に端子1をセットし、丸型バレルからなる芯線挿入筒部10の前端10aから加締め部10bの後端位置までを、図3(C)に示すように加締め固着する。該加締め圧着により電線接続部の円筒の上側部が偏平状に加締められ、加締め部10b内の芯線21は該加締め部10bの内周面に密着固着される。其の際、芯線挿入筒部10の前端10aを斜め傾斜させているとともに、内部の芯線21が前端10aに突出させないため、加締め圧着時に前端10aの上下面が重なるように加締め圧着され、芯線21の先端を隙間がない密閉する状態で前端開口を閉鎖する。
Next, the terminal 1 is set in a crimping crimping device (not shown), and the
前記のように、端子1と電線端末の芯線21を丸型バレルからなる芯線挿入筒部10内で加締め固着するとともに、絶縁被覆23に密嵌したゴム栓15を端子1に弾性圧縮して挿入固着しているため、電気接続信頼性の向上と止水性能の向上とを図ることができる。
