【発明の属する技術分野】
本発明は、例えば自動車用ワイヤハーネスにおける電線の何本かを分岐などの目的で別の電線と接続した場合に、その接続部を電気的に絶縁した状態で保護するための電線接続部用保護クリップに関する。
【0002】
【従来の技術】
このように電線の接続部を絶縁して保護する技術の一例が図10に示されている。この技術では、まず図10(A)で示すように電線50と分岐用の電線52との接続部54に熱収縮性の素材からなる絶縁チューブ60を被せる。そしてこの絶縁チューブ60を加熱することにより、図10(B)で示すように収縮させて前記接続部54を電気的に絶縁すると同時に保護している。
【0003】
【発明が解決しようとする課題】
ところが前記絶縁チューブ60の取り付けは、この絶縁チューブ60に電線50の一端を挿入し、かつ絶縁チューブ60を前記接続部54に向けて移動させるといった手間を要し、しかもその後に絶縁チューブ60を前記のように加熱する作業も必要である。また前記絶縁チューブ60で保護した後であっても、前記接続部54に大きな引っ張り力が加わると、絶縁チューブ60が破断されるだけでなく、接続部54がちぎれてしまう場合もある。
【0004】
本発明の目的は、ワンタッチで電線の接続部を電気的に絶縁すると同時に各電線の外周を把持してそれぞれの位置決めを果たすことにより、電線の接続部を絶縁して保護する作業の簡素化を図り、また接続部に加わる引っ張り力に対しても接続状態の保持を可能とすることである。
【0005】
【課題を解決するための手段】
請求項1記載の発明は、クリップ本体と蓋体とがヒンジによって結合されているとともに、クリップ本体と蓋体とを合わせることにより、これら相互が前記ヒンジの反対側で係合状態に保持されるように構成され、クリップ本体と蓋体との合わせ部には、収容部がそれぞれ形成され、クリップ本体における収容部の両側にはリブが形成されているとともに、蓋体における収容部の両側には押さえ部が形成され、クリップ本体における収容部の一方側には二つのリブと、両リブの間に位置する凹部とが形成され、蓋体における収容部の一方側には二つの押さえ部と、両押さえ部の間に位置する突片とが形成され、収容部に電線の接続部を入れてクリップ本体と蓋体とを互いに合わせたときに、リブと押さえ部とにより、接続部の両側において電線の外周を把持するとともに、二つのリブ間の凹部に二つの押さえ部間の突片が差し込まれるように構成されていることを特徴とする。
【0006】
この構成によれば、クリップ本体と蓋体とを、これら相互の収容部に電線の接続部を入れた後にワンタッチで係合状態とすることにより、電線の接続部が電気的に絶縁されるとともに、接続部の両側に位置する電線の外周がリブと押さえ部とによって把持される。このため、電線に加わる引っ張り力に対して充分に持ちこたえ、電線の接続状態を適正に保持する。しかも、クリップ本体と蓋体とを合わせて係合させたときに、クリップ本体の凹部に蓋体の突片が差し込まれ、この突片が二つのリブに対するクサビ効果を果たし、この箇所での電線の把持力が高められる。
【0008】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。
図1は保護クリップを表した外観斜視図、図2は同じく保護クリップを表した平面図、図3は図2の左側面図、図4は同じく図2の右側面図である。これらの図面で示すように保護クリップは、主としてクリップ本体10と蓋体30とから構成され、これらの相互は薄肉のヒンジ20によって結合されている。すなわちこの保護クリップは樹脂材による一体成型品であって、前記ヒンジ20の弾性(可撓性)によりクリップ本体10と蓋体30とを互いに合わせることができるようになっている。
【0009】
図5は図2のA−A線断面図、図6は同じく図2のB−B線断面図、図7は同じく図2のC−C線断面図である。これらの図面からも明らかなように、前記クリップ本体10及び蓋体30におけるそれぞれの中央部には、その大部分の領域にわたって凹形状の収容部12,32が形成されている。そしてクリップ本体10における収容部12の一方側(図2の右側)中央で、この収容部12を開放させるように半円弧状にへこませた部分の内部には一つのリブ14が形成されている。また収容部12の他方側(図2の左側)の開放部には、二つのリブ16が並列に形成されている。なおこれらの両リブ16の間には凹部18が形成されている。
【0010】
一方、前記蓋体30における収容部32の一方側(図2の右側)中央には、この収容部32を開放させるように半円弧状にへこませた一つの押さえ部34が形成されている。さらにこの収容部32の他方側(図2の左側)には、同じように半円弧状にへこませた二つの押さえ部36が並列に形成されている。これらの両押さえ部36の間には突片38が形成されている。
【0011】
前記クリップ本体10のリブ14,16と前記蓋体30の押さえ部34,36とは、前記のようにヒンジ20の可撓性によってクリップ本体10と蓋体30とを互いに合わせたときに、個々の位置が合致するように設定されている。またこのときにクリップ本体10の前記凹部18に蓋体30の前記突片38が差し込まれるようになっている。しかもクリップ本体10及び蓋体30には、ヒンジ20の反対側において係合孔19と係合爪39とがそれぞれ形成されている。
【0012】
つづいて前記のように構成された保護クリップの使用について説明する。
この実施の形態では図8で示すように電線50に分岐用の電線52が接続されたものを対象とし、その接続部54を前記クリップ本体10の収容部12に位置させる。このとき、電線50については前記一つのリブ14と二つ並列のリブ16のうちの一方との上にそれぞれ位置させ、かつ電線52はリブ16のうちの他方の上に位置させておく。
【0013】
この状態で図9で示すように前記蓋体30とクリップ本体10とを互いに接合させると、クリップ本体10の前記係合孔19に蓋体30の前記係合爪39が係合する。これと同時に前記の各リブ14,16上に位置している電線50,52の外周が、これらのリブ14,16と蓋体30の各押さえ部34,36とによって局部的に挟み付けられた状態で把持される。しかも前記リブ16の間の凹部18に蓋体30の突片38が差し込まれることにより、この突片38が両リブ16に対するクサビ効果を果たし、この箇所での電線50,52の把持力がより高められる。
【0014】
このように前記クリップ本体10の各リブ14,16と、前記蓋体30における各押さえ部34,36とにより、これらのクリップ本体10と蓋体30との合わせ部において前記電線50,52の外周をそれぞれ把持する「クランプ部」が構成されている。なお各リブ14,16と各押さえ部34,36との関係は相対的なものであり、クリップ本体10が押さえ部34,36を備え、蓋体30がリブ14,16を備えた構成も当然可能である。
【0015】
本実施の形態においては、前記クリップ本体10と蓋体30とをワンタッチで図9で示す状態に接合させることができ、これによって電線50,52の接続部54を電気的に絶縁すると同時に前記リブ14,16と押さえ部34,36とにより電線50,52の外周を把持してその位置決めを果たすことができる。したがって前記接続部54を適正に保護できるのはもちろんのこと、電線50,52に加わる引っ張り力に対しても前記接続部54がちぎれるといった事態を防止できる。
