【発明の属する技術分野】
本発明は、架設対象のケーブル体を接続したケーブル体架設具を、既に架設された先設ケーブル体に支持させた状態でその先設ケーブル体に沿わせて押送することで架設対象ケーブル体を架設するケーブル体架設作業において、ケーブル体架設具と架設対象ケーブル体とを接続する接続コネクタに関する。
【0002】
【従来の技術】
従来の接続コネクタは、ケーブル体架設具を接続する雄ネジ部を備えた雄ネジ具と、その雄ネジ具に対し揺動自在な状態で連結された架設対象ケーブル接続用の連結体と、雄ネジ具と連結体とに亘る状態で、それら雄ネジ具と連結体とに対し摺動自在に外嵌する円筒部とから構成されている。
【0003】
円筒部は、筒軸芯方向に一直線状に位置させた雄ネジ具と連結体とに亘る状態で外嵌することで、連結体の雄ネジ具に対する揺動を規制した固定状態を現出し、その円筒部は付勢手段により前記固定状態を維持する側に付勢されている。
【0004】
そして、上記固定状態から円筒部を付勢手段の付勢力に抗し固定状態解除側に摺動させて雄ネジ具と連結体との連結箇所を円筒部から露出させる(即ち、雄ネジ具と連結体とに亘る外嵌を解除する)ことで、雄ネジ具に対し連結体が揺動自在となる可動状態を現出する。
【0005】
このような固定状態と可動状態とに切り換え可能な接続コネクタを用いてケーブル体架設具と架設対象ケーブル体とを接続すると、架設対象ケーブル体を接続してあるケーブル体架設具を先設ケーブル体に装着する際には、接続コネクタを可動状態にして、連結体に接続の架設対象ケーブル体に対し雄ネジ具に接続のケーブル体架設具を揺動自在にすることで、垂れ下がる架設対象ケーブル体の存在にかかわらず装着作業の自由度を高めることができて、架設対象ケーブル体が装着作業の邪魔になることを解消することができる。
【0006】
そして、ケーブル体架設作業を行なう際には、接続コネクタを可動状態から固定状態に切り換えると、雄ネジ具に接続のケーブル体架設具と連結鯛に接続の架設対象ケーブル体とを一直線状に固定することで、架設対象ケーブル体の押出操作によるケーブル体架設具の先設ケーブル体に沿わせての押送が容易になる(例えば、非特許文献1参照。)。

【発明が解決しようとする課題】
しかし、上述の従来の接続コネクタでは、前記可動状態から前記固定状態へ切り換えるのに、即ち、円筒部を付勢手段の付勢力により雄ネジ具と連結体とに亘る状態に復帰移動させて前記固定状態を現出するのに、架設対象ケーブル体が接続された連結体をケーブル体架設部接続側の雄ネジ部と円筒部の筒軸芯方向で一直線状になるように揺動操作をしなければならず手間がかかる。
【0009】
この実情に鑑み、本発明の主たる課題は、上記問題を合理的な改良を以って効果的に解消する点にある。
【0010】
【課題を解決するための手段】
〔1〕請求項1に係る発明は接続コネクタに係り、その特徴は、
架設対象のケーブル体を接続したケーブル体架設具を、既に架設された先設ケーブル体に支持させた状態でその先設ケーブル体に沿わせて押送することにより架設対象ケーブル体を架設するケーブル体架設作業において、ケーブル体架設具と架設対象ケーブル体とを接続する接続コネクタにおいて、
ケーブル体架設具を接続するコネクタ本体と、架設対象ケーブル体を接続する連結体と相対揺動自在に、且つ、ケーブル体架設具押し方向の所定幅で相対移動可能に連結する連結手段が設けられているとともに、前記連結体と前記コネクタ本体との間には、連結体が前記コネクタ本体に対してケーブル体架設具押送向きに押し操作されて連結体とコネクタ本体とが相対移動限界位置に位置したときに連結体とコネクタ本体とがケーブル体架設具押し方向で一直線状になった所定姿勢で当接して該連結体とコネクタ本体との相対揺動を規制する姿勢固定手段が設けられ、
前記姿勢固定手段は、前記コネクタ本体のケーブル体架設具押し方向における架設対象ケーブル体接続側に、ケーブル体架設具押し方向でコネクタ本体の架設対象ケーブル体接続側端の側ほどケーブル体架設具押し方向に対する直行方向の外方に広がる押し側の受止テーパー面を形成するとともに、前記連結体に、前記押し操作によって連結体とコネクタ本体とが押し側の相対移動限界位置に位置したときに前記所定姿勢で前記受止テーパー面と当接する押し側の接当テーパー面部を設けて構成されている点にある。
【0011】
つまり、この構成によれば、ケーブル体架設具とコネクタ本体、架設対象ケーブル体と連結体をそれぞれ接続した後、ケーブル体架設具を既に架設された先設ケーブル体に支持させた状態で、架設対象ケーブル体を介して連結体をコネクタ本体に対し押し操作することによりケーブル体架設具を先設ケーブル体に沿わせて押送すると、自動的に連結体に接続の架設対象ケーブル体とコネクタ本体に接続のケーブル体架設具とがケーブル体架設具の押し方向で一直線状の姿勢に固定された固定状態となるので、従来の接続コネクタのように、架設対象ケーブル体が接続された連結体をケーブル体架設具接続側の雄ネジ具と一直線状の姿勢になるように揺動操作することで、円筒部を連結体と雄ネジ具とに亘って外嵌させるといった手間がかからず、容易でかつ確実に接続コネクタを固定状態にすることができ、そのことにより、迅速でかつ容易にケーブル体架設作業を実施することができる。
【0013】
そして、連結体をコネクタ本体に対し押し操作すると、コネクタ本体に形成された押し側受止テーパー面と連結体に形成された押し側接当テーパー面部とが相互の接触案内作用下で当接状態に至って固定状態を現出するので、連結体とコネクタ本体とのそれぞれにテーパー面を形成するといった簡単な構造でありながら、押し操作による可動状態から固定状態への切り換えが極めて円滑なものになり、そのことで、架設作業の作業性を一層高めることができる。
【0014】
〔2〕請求項に係る発明は、請求項に係る発明の実施に好適な実施形態を特定するものであり、その特徴は、
前記コネクタ本体が、ケーブル体架設具押し方向に沿う筒軸芯を備える筒状に形成され、その内周面に、コネクタ本体半径方向の内方に括れる括れ部が形成されているとともに、前記連結体には前記括れ部に嵌通可能な嵌通部が形成されていて、
前記姿勢固定手段は、前記括れ部のコネクタ本体長手方向における架設対象ケーブル体接続側に、コネクタ本体長手方向でコネクタ本体の架設対象ケーブル体接続側端の側ほどコネクタ本体半径方向の外方に広がる押し側の受止テーパー面を形成し、括れ部のコネクタ本体長手方向におけるケーブル体架設具接続側に、コネクタ本体長手方向でコネクタ本体のケーブル体架設具接続側端の側ほどコネクタ本体半径方向の外方に広がる引き側の受止テーパー面を形成するとともに、前記連結体の嵌通部に、前記押し操作によって連結体とコネクタ本体とが押し側の相対移動限界位置に位置したときに前記所定姿勢で前記押し側受止テーパー面と当接する押し側の接当テーパー面部と、前記引き操作によって連結体とコネクタ本体とが引き側の相対移動限界位置に位置したときに前記所定姿勢で前記引き側受止テーパー面に当接する引き側の接当テーパー面部とを設けて、前記連結体が前記コネクタ本体に対してケーブル体架設具押送向きに押し操作されて連結体とコネクタ本体とが押し側の相対移動限界位置に位置したときと、連結体がコネクタ本体に対してケーブル体架設具押送向きとは反対向きに引き操作されて連結体とコネクタ本体とが引き側の相対移動限界位置に位置したときの夫々において前記所定姿勢で当接して連結体とコネクタ本体との相対揺動を規制し、連結体とコネクタ本体とを両相対移動限界位置の間に位置させたときに前記規制を解除する構成にしてある点にある。
【0015】
つまり、この構成によれば、上記固定状態を、連結体をコネクタ本体に対して押し操作したときだけでなく、連結体をコネクタ本体に対し引き操作したときにも現出することができ、また、連結体をそれら押し止め位置と引き止め位置と間に位置させたときに、連結体を可動状態にすることができるので、ケーブル体架設作業において、連結体に接続された架設対象ケーブル体における押し操作によるケーブル体架設具の押送を容易にする固定状態と、接続コネクタをケーブル体架設具に接続操作及び離脱操作を容易にする可動状態と、架設対象ケーブル体における引き操作によるケーブル体架設具の牽引を容易にする固定状態とに簡便に切り換えることができので、ケーブル体架設作業を迅速でかつ容易に実施することができる。
【0017】
また、この構成によれば、連結体をコネクタ本体に対し押し操作すると、押し側受止テーパー面と押し側接当テーパー面部とが相互の接触案内作用下で当接状態に至って固定状態を現出する。
そして、押し側の固定状態から連結体をコネクタ本体に対し引き操作すると、押し側受止テーパー面と押し側接当テーパー面部とが当接していない状態、かつ、コネクタ本体に形成された引き側受止テーパー面と連結体に形成された引き側接当テーパー面部とが当接していない状態にある可動状態を現出し、また、その可動状態からの引き操作によって引き側受止テーパー面と引き側接当テーパー面部とが相互の接触案内作用下で当接状態に至って固定状態を現出するので、連結体とコネクタ本体とのそれぞれにテーパー面を形成するといった簡単な構造でありながら、押し操作及び引き操作による可動状態から固定状態への切り換え、及び、固定状態から可動状態への切り換えが極めて円滑なものになり、そのことで架設作業の作業性を一層高めることができる。
【0018】
【発明の実施の形態】
〔第1実施形態〕
図1〜図7は本願発明の第1実施形態を示し、電柱P1,P2間に張設されているメッセンジャーワイヤーMに、同じく電柱P1,P2間に架設する電線等のケーブルBを懸架する懸架具Hの一例であるケーブルハンガー9を釣支し、このケーブルハンガー9の環状に形成されているケーブル抱込部hに先設の本設ケーブルBを抱え込み状に挿通した状態で懸架してあるケーブル施設において、架設対象ケーブル体である追加ケーブル10をケーブルハンガー9のケーブル抱込部hに挿通させて追加架設する際、そのケーブル抱込部hに先立って挿通させ引き戻すことで追加ケーブル10を架設するファイバロッド11(別の架設対象ケーブル体)に、先立って挿通させるためのケーブル体架設具の一例である通線ガイド具Gが接続コネクタCを介して接続される。
【0019】
通線ガイド具Gの本体1は、2つの分割部分1A,1Bを枢支連結して構成され、その一方の本体分割部分1Aに対し他方の本体分割部分1Bを枢支軸芯X周りで相対的に開き揺動させて本設ケーブルBに対するガイド具本体1の着脱操作を可能にする開き状態と、一方の本体分割部分1Aに対し他方の本体分割部分1Bを枢支軸芯X周りで相対的に閉じ揺動させてガイド具本体1本設ケーブルBに外嵌させる閉じ状態とに切り換え可能に構成されている。
また、ガイド具本体1を閉じ状態にした時には、その内側に本設ケーブルBを相対摺動自在に位置させる円筒空間状の先設ケーブル体嵌装部Sを形成するとともに、両本体分割部分1A,1Bには、先設ケーブル体長手方向に延びる嵌合孔7が形成してあり、この嵌合孔7はガイド具本体1における先設ケーブル体嵌装部Sの内径D1を種々の本設ケーブルBの外径D2に適応させるための分割インナースペーサー8をガイド具本体1に装着するための取付け部として機能する。
【0020】
そして、2つの本体分割部分1A,1Bのそれぞれにおける先設ケーブル体長手方向の一端側には、ガイド具本体1が閉じ状態にあるとき集合して架設対象ケーブル体接続部2を形成する接続部形成片2a,2bを設けてあり、一方の本体分割部分1Aの接続部形成片2aの先端部には、ガイド具本体1とファイバロッド11との間に介在させる接続コネクタC(雌ネジ具)を螺着する雄ネジ部3が突設されている。
【0021】
接続コネクタCは、先設ケーブル体長手方向の一端に形成した雌ネジ部4aによりガイド具本体1の雄ネジ部3に螺着するコネクタ本体4と、ファイバロッド11と連結してある連結体5、6とから構成されている。
【0022】
連結体5、6は、コネクタ本体4の先設ケーブル体長手方向他に設けられた屈曲操作ピン具5とそれに嵌合するリング6から構成され、この接続コネクタCは、ガイド具本体1とファイバロッド11との間に介在してガイド具本体1に対しファイバロッド11を接続する。また、この接続コネクタCは、ガイド具本体1を閉じ状態で固定する固定具を兼ねている。
【0023】
そして、この接続コネクタCは、連結体5、6に接続されたファイバロッド11を以って連結体5、6をコネクタ本体4に対し押し操作することで連結体5、6とコネクタ本体4とをその押し方向(即ち、先設ケーブル体長手方向)に一直線状の所定姿勢に固定された固定状態と、連結体5、6とコネクタ本体4とが相対揺動自在な可動状態と、ファイバロッド11を以って連結体5、6をコネクタ本体4に対し引き操作することで連結体5、6とコネクタ本体4とを先設ケーブル体長手方向に一直線状の所定姿勢に固定された固定状態とに切り換え操作可能に構成されている。
換言すれば、接続コネクタCにおける連結体5、6とコネクタ本体4との間には、連結体5、6に接続されたファイバロッド11を以って連結体5、6がコネクタ本体4に対してケーブル体架設具押送向きに押し操作されたときに当接して、前記所定姿勢で連結体5、6とコネクタ本体4との相対揺動を規制することにより前記固定状態を現出するとともに、ファイバロッド11を以って連結体5、6をコネクタ本体4に対して、ケーブル体架設具押送向きとは反対向きに引き操作されたときに当接して、前記所定姿勢で連結体5、6とコネクタ本体4との相対揺動を規制することにより前記固定状態を現出する姿勢固定手段が設けられている。
【0024】
接続コネクタCの構造を詳しく説明すると、図1〜図3に示すように、コネクタ本体4は、その内周面におけるファイバロッド11寄り(即ち、先設ケーブル体長手方向における他端寄り)の一部がコネクタ本体半径方向(即ち、先設ケーブル体長手方向に対する直行方向)内方に括れていて、その括れ部4bからファイバロッド11の側の端に向かってコネクタ本体半径方向外方に広がる押し側受止テーパー面部4cと、その括れ部4bからガイド具本体1の側(即ち、先設ケーブル体長手方向における一端側)に向かってコネクタ本体半径方向外方に広がる引き側受止テーパー面部4dとがコネクタ本体4の内部に形成されている。
【0025】
これに対し、屈曲操作ピン具5は、括れ部4bの内径よりも小径に形成された先設ケーブル体長手方向における一端側の挿入ピン5aと、コネクタ本体4の押し側受止テーパー面部4cに密接(当接)させる押し側接当テーパー面部5dを有する中央部5bと、ファイバロッド11に対し外嵌固着する先設ケーブル体長手方向における他端側の嵌合部5cとから形成され、挿入ピン5aがコネクタ本体4に先設ケーブル体長手方向における他端側から挿入されている。
【0026】
また、引き側受止テーパー面部4dに密接(当接)させる引き側接当テーパー面部6aを有するリング6と、そのリング6を固定するリング留め具6Aとが、コネクタ本体4に先設ケーブル体長手方向における一端側からコネクタ本体4に挿入され、屈曲操作ピン具5がコネクタ本体4に対し先設ケーブル体長手方向で所定の範囲内において摺動するのを許す状態で、それらリング6及びリング留め具6Aを挿入ピン5aに対して外嵌固着してあり、もって、コネクタ本体4と連結体5,6とを相対揺動自在に、且つ、先設ケーブル体長手方向の所定の範囲内において相対移動可能に連結してある。(すなわち、屈曲操作ピン具5、リング6、リング留め具6Aは、コネクタ本体4と連結体5、6とを相対揺動自在に、且つ、ケーブル体架設具押し方向の所定幅で相対移動可能に連結する連結手段を構成する。)
【0027】
つまり、屈曲操作ピン具5の中央部5bの押し側接当テーパー面部5dがコネクタ本体4の押し側受止テーパー面部4cに密接(当接)している状態(即ち、押し止め位置にあるとき、換言すれば、連結体5、6とコネクタ本体4とが押し側の相対移動限界位置にあるとき)、及び、リング6の引き側接当テーパー面部6aがコネクタ本体4の引き側受止テーパー面部4dに密接(当接)した状態(即ち、引き止め位置にあるとき、換言すれば、連結体5、6とコネクタ本体4とが引き側の相対移動限界位置にあるとき)のそれぞれにおいて連結体5、6の屈曲操作ピン具5がコネクタ本体4に対し固定された(即ち、連結体5、6とコネクタ本体4とが前記所定姿勢で相対揺動を規制された)固定状態になるとともに、押し側接当テーパー面部5dと押し側受止テーパー面部4cとが離間した状態で、かつ、引き側接当テーパー面部6aと引き側受止テーパー面部4dとが離間した状態で(即ち、連結体5、6とコネクタ本体4とが押し側の相対移動限界位置と引き側の相対移動限界位置の間にあるとき)は、屈曲操作ピン具5とコネクタ本体4とが相対揺動可能な可動状態になるようにしてある。
尚、本実施形態において前記姿勢固定手段は、連結体5、6の押し側接当テーパー面部5d及び引き側接当テーパー面部6aと、コネクタ本体の押し側受止テーパー面部4c及び引き側受止テーパー面部4dとから構成されている。
【0028】
そして、図4及び図5に示すように、接続具と固定具とを兼ねる接続コネクタCは、ファイバロッド11を接続した状態で、コネクタ本体4の雌ネジ部4aを一方の本体分割部分1Aにおける接続部形成片2aの雄ネジ部3に対してのみ螺嵌させた状態では、ファイバロッド11とガイド具本体1とを接続状態にしながらも一方の本体分割部分1Aに対して他方の本体分割部分1Bが相対的に開閉揺動することを許し、その後、ガイド具本体1が閉じ状態にある状況下で更に雄ネジ部3に対する雌ネジ部4aの螺入操作を進行させると、コネクタ本体4の雌ネジ部4aが、一方の本体分割部分1Aにおける接続部形成片2aと他方の本体分割部分1Bにおける接続部形成片2bとの集合により形成された架設対象ケーブル体接続部2に外嵌してそれら接続部形成片2a,2bを結束し、これによって、一方の本体分割部分1Aに対して他方の本体分割部分1Bが相対的に開閉揺動することを不能にして、ガイド具本体1を閉じ状態に固定する。
【0029】
図6及び図7に示す、2本の電柱P1,P2間に上記構成の通線ガイド具Gを用いて、追加ケーブル10を架設するケーブル追加架設作業工程を説明する。
【0030】
まず、本設ケーブルBの外径D2に適応する分割インナースペーサー8を選択し、その分割インナースペーサー8の各分割部分をガイド具本体1の各本体分割部分1A,1Bに装着する。
【0031】
次に、接続コネクタCの屈曲操作ピン具5の嵌合部5cにファイバロッド11を内嵌し、嵌合部5cをかしめることでファイバロッド11を嵌合部5cに固着したのち、ガイド具本体1の一方の本体分割部分1Aに設けられている雄ネジ部3に対し接続コネクタCのコネクタ本体4における雌ネジ部4aを螺着する。
【0032】
そして、雄ネジ部3にのみ接続コネクタCを螺装した状態のガイド具本体1、即ち、ガイド具本体1に対し接続コネクタCを介してファイバロッド11を接続した状態でありながら、他方の本体分割部分1Bが一方の本体分割部分1Aに対して相対的に開閉揺動することを許す状態にあるガイド具本体1を、第1作業者W1が手にして一方の電柱P1に上り、その電柱P1上でガイド具本体1を開き状態から閉じ状態にして本設ケーブルBに外嵌装着する。
【0033】
第1作業者W1は、第3作業者W3の操作によりロッドリール12から繰り出されるファイバロッド11を手繰りながら、他方の電柱P2に上っている第2作業者W2に向かって、そのファイバロッド11で押し出すようにしてガイド具本体1を本設ケーブルBに沿わせて摺動押送し、そして、この押送において、本設ケーブルBを懸架するケーブルハンガー9のケーブル抱込部hにガイド具本体1及びそれに接続されているファイバロッド11を通過させる。
【0034】
このとき、接続コネクタCは、押し操作によりコネクタ本体4の押し側受止テーパー面部4cと屈曲操作ピン具5の中央部5bの押し側接当テーパー面部5dとが密接(当接)した固定状態になっており、これによって、ガイド具本体1とファイバロッド11とをケーブルハンガー9のケーブル抱込部hに押送するのが容易になる。
【0035】
第2作業者W2は、第1作業者W1から届いたガイド具本体1を本設ケーブルBから外して下方の第4作業者W4に渡し、第4作業者W4はファイバロッド11からガイド具本体1を取り外して、接続コネクタCにケーブル接続用フック13を介して追加ケーブル10を接続したのち、第3作業者W3がファイバロッド11をロッドリール12に巻き取り、一方の電柱P1側に引き戻すことで、追加ケーブル10を本設ケーブルBと共にケーブルハンガー9のケーブル抱込部hに挿通させた一束化状態に架設する。
【0036】
そして、ファイバロッド11を引き戻している時、接続コネクタCは、引き操作によりコネクタ本体4の引き側受止テーパー面部4dと屈曲操作ピン具5に嵌合したリング6の引き側接当テーパー面部6aと密接(当接)した固定状態になっており、これにより、接続コネクタCを介して追加ケーブル10を接続しているファイバロッド11を容易に引き戻すことができる。
【0037】
〔第2実施形態〕
図8及び図9は本願発明の第2実施形態を示し、先設の本設ケーブルBが存在しない新設ケーブル施設において、2本の電柱P1,P2間に先設ケーブル体の一例であるメッセンジャーワイヤーMを張設し、メッセンジャーワイヤーMにケーブル用の懸架具Hであるスパイラルハンガー14(コイルハンガー)を取り付けたのち、極小径の先設ケーブル体(例えば、メッセンジャーワイヤーM)用の分割インナースペーサー8を装着し、かつ、ファイバロッド11を固着した接続コネクタCを架設対象ケーブル体接続部2に接続したガイド具本体1をメッセンジャーワイヤーMに外嵌装着する。
そして、そのガイド具本体1を一方の電柱P1の側からメッセンジャーワイヤーMに沿って他方の電柱P2に向かって、ファイバロッド11を以って押送することで、ファイバロッド11をスパイラルハンガー14のケーブル抱込部hに挿通するとともに、他方の電柱P2の側において、届いたガイド具本体1に代え新設ケーブル15を、接続コネクタCを介してファイバロッド11に接続し、一方の電柱P1の側からファイバロッド11を引き戻して新設ケーブル15をスパイラルハンガー14のケーブル抱込部hに挿通させることで、新設ケーブル15を架設する。
【0038】
〔第3実施形態〕
図10は、本願発明の第3実施形態を示し、先設の本設ケーブルBが存在しない新設ケーブル施設において、2本の電柱P1,P2間に先設ケーブル体の一例であるメッセンジャーワイヤーMを張設し、メッセンジャーワイヤーMにケーブル体架設具の一例である複数の移動金具16のそれぞれを紐状部材で連結した状態で垂下させ、ファイバロッド11を固着した接続コネクタCを先頭の移動金具16aの接続部に螺着させる。
そして、ファイバロッド11を以って移動金具16を一方の電柱P1の側からメッセンジャーワイヤーMに沿って他方の電柱P2に向かって押し出すように移動させ、他方の電柱P2の側において届いた先頭の移動金具16aに代え新設ケーブル15を接続コネクタCを介してファイバロッド11に接続し、一方の電柱P1の側からファイバロッド11を引き戻して新設ケーブル15を架設する。
【0039】
〔別の実施形態〕
本発明の実施において、接続コネクタCは、それのコネクタ本体4及び連結体5、6にテーパー面を形成してある構成を以って、押し操作や引き操作による固定状態、及び、可動状態を現出したが、その構成は上記の構成に限るのもではなく、種々のものであってもよい。
【0040】
接続コネクタCのコネクタ本体4と連結体5、6との連結構造は、可動状態において、一軸周りでのみ揺動自在にする構造あってもよく、ユニバーサルジョイントのように複数方向に揺動自在にする構造であってもよい。
【0041】
上記第1、第2及び第3実施形態における接続コネクタCでは、コネクタ本体4にケーブル体架設具との接続部として雌ネジ部4aを設けたが、雌ネジ部4aに限定されるものではなく、ケーブル体架設具の架設対象ケーブル体接続部の構成に対応して変更可能である
【0042】
同様に、屈曲操作ピン具5に、ファイバロッド11と接続する嵌合部を設け、内嵌させたファイバロッド11をかしめて接続したが、屈曲操作ピン具5とファイバロッド11との接続手段においても、上記の構成に限ったのもではない。
【0043】
上記第1実施形態では、架設対象ケーブル体接続部2に通線案内用のファイバロッド11を接続コネクタCを介し接続したガイド具本体1を、本設ケーブルBに装着し、そのガイド具本体1を一方の電柱P1の側から本設ケーブルBに沿わせて押送させる形態でケーブルハンガー9のケーブル抱込部hに挿通させたのち、他方の電柱P2の側でファイバロッド11に追加ケーブル10を接続して、ファイバロッド11を一方の電柱P1の側に引き戻すことにより、ケーブル追加架設作業を行い、
また、上記第2実施形態では、架設対象ケーブル体接続部2に通線案内用のファイバロッド11を接続コネクタCを介し接続したガイド具本体1を、メッセンジャーワイヤーMに装着し、そのガイド具本体1を一方の電柱P1の側からメッセンジャーワイヤーMに沿わせて摺動移動させる形態でスパイラルハンガー14のケーブル抱込部hに挿通させたのち、他方の電柱P2の側でファイバロッド11に新設ケーブル15を接続して、ファイバロッド11を一方の電柱P2の側に引き戻すことにより、新設ケーブル架設作業を行うが、
後端に架設対象ケーブル体である追加ケーブル10又は新設ケーブル15を接続したファイバロッド11の先端を接続コネクタCを介し架設対象ケーブル体接続部2に接続したガイド具本体1を、先設ケーブル体としての本設ケーブルB又はメッセンジャーワイヤーMに装着し、そのガイド具本体1を一方の電柱P1の側から本設ケーブルB又はメッセンジャーワイヤーMに沿わせて押送させる形態で懸架具Hのケーブル抱込部hに挿通させたのち、ファイバロッド11を他方の電柱P2の側から引っ張って、ケーブル追加架設作業又は新設ケーブル架設作業を行なってもよい。
【0045】
上記第1及び第2実施形態では、ガイド具本体1は本体分割部分1A,1Bは2分割に構成してあるが、ガイド具本体1は必ずしも2分割構成に限るものではない。
【0046】
上記第3実施形態では、先設ケーブル体としてメッセンジャーワイヤーMが張設されているが、メッセンジャーワイヤーMに限ったものではなく、自己支持型ケーブル体等の種々のものであってよい。

BACKGROUND OF THE INVENTION
In the present invention, the cable body installation tool connected to the cable body to be installed is supported by the existing cable body that has already been installed. The present invention relates to a connection connector for connecting a cable body installation tool and an installation target cable body in a cable body installation work.
[0002]
[Prior art]
A conventional connection connector includes a male screw tool having a male screw part for connecting a cable body installation tool, a connector for connecting a cable to be installed connected in a swingable manner to the male screw tool, and a male connector. It is comprised from the cylindrical part which slidably fits with respect to these male screw tools and a connection body in the state over a screw tool and a connection body.
[0003]
The cylindrical portion is externally fitted in a state extending over the male screw tool and the coupling body that are positioned in a straight line in the cylinder axis direction, thereby revealing a fixed state in which swinging of the coupling body with respect to the male screw tool is restricted, The cylindrical portion is urged to the side maintaining the fixed state by the urging means.
[0004]
Then, the cylindrical portion is slid against the urging force of the urging means from the fixed state and is slid to the fixed state release side to expose the connection portion between the male screw tool and the connecting body from the cylindrical portion (ie By releasing the external fitting over the connecting body), a movable state in which the connecting body can swing with respect to the male screw tool appears.
[0005]
When the cable body installation tool and the installation target cable body are connected using the connection connector that can be switched between the fixed state and the movable state, the cable body installation tool to which the installation target cable body is connected is connected to the pre-installed cable body. When mounting to the cable body, the connecting connector is made movable, and the cable body installation tool connected to the male screw tool is swingable with respect to the installation object cable body connected to the coupling body, so that the installation target cable body is suspended. The degree of freedom of the mounting work can be increased regardless of the presence of the cable, and it is possible to eliminate the fact that the installation target cable body obstructs the mounting work.
[0006]
When the cable body erection work is performed, when the connection connector is switched from the movable state to the fixed state, the cable body erection tool connected to the male screw tool and the erection target cable body connected to the connecting rod are fixed in a straight line. By doing so, it becomes easy to push the cable body installation tool along the pre-installed cable body by pushing out the cable body to be installed (see Non-Patent Document 1, for example).
