【発明の属する技術分野】
本発明は、配電線から需要者の建物に引留碍子を介して引込まれる配電線用引込線に添わせて光ケーブルの引込線を配設する場合、該光ケーブルの引込線を前記配電線用引込線または引留碍子用フックに保持しておくための光ケーブルの保持具に関するものである。
【０００２】
【従来の技術】
近時、情報化社会が進む中では、搬送すべき情報量も格段に増加しているところ、従来のメタル製の通信線では性能を満足し得ないため、これを解決すべく通信線自体の光ケーブル化が進んでいる。ところで、一般に電柱には配電線と共に通信線が架設されており、近年インターネット等の普及により、これを一般需要家の建物内に引き込むケースが増えてきている。この場合、電柱上の分岐部から建物側まで、新たに光ケーブルの引込線を架設することになる。
【０００３】
【発明が解決しようとする課題】
そこで、前記分岐部から引き出される光ケーブルの引込線を新たに建物側に配設するには、例えば建物外壁の適宜位置に螺子などを使用して掛止金具を固定し、そこに光ケーブルの引込線を一旦保持してから建物側に導く方法が考えられるが、この場合は、新たに掛止金具が必要となるばかりか配設工事に余分な手間や時間が掛かり、しかも、新築の建物であると外壁にキズをつけるなど需要者に余分な負担を掛けさせといったことにもなる。よって、できれば既存の設備を利用でき、しかも工事が簡単に能率良く行なえるようにすることが望ましい。
そこで、本発明は上記課題を解決すべくなされたもので、既存の設備を利用して簡単に取り付けられ需要者に余分な負担を掛けずに済み、しかも構造が簡単であって成形が容易である光ケーブルの保持具を提供することを目的とするものである。
【０００４】
【課題を解決するための手段】
かかる目的を達成するため本発明に係る光ケーブルの保持具は、配電線用引込線または該配電線用引込線の引留碍子用フックに掛止するための掛止部と、光ケーブルの引込線を保持する保持部と、を備えた構成よりなる。このような光ケーブルの保持具を使用することにより例えば既存の引留碍子用フックに簡単に掛止でき、しかも需要者に余分な負担を掛けずに済む。
【０００５】
前記光ケーブルの保持具としては、例えば配電線用引込線または該配電線用引込線の引留碍子用フックに掛止するための掛止部と光ケーブルの引込線を保持する保持部とを備え、該保持部は断面コ字状をなすと共にその内側の一側面にこれと対向する他側面側に付勢される弾力舌片が設けられ、前記両側面間に介挿される光ケーブルの引込線を弾力舌片と他側面とで挟着するようにして構成される。
【０００６】
また、配電線用引込線または該配電線用引込線の引留碍子用フックに掛止するための掛止部と光ケーブルの引込線を保持する保持部とを備え、該保持部は線材をコイル状に巻回すると共に光ケーブルの許容曲げ半径以上の範囲で曲がる筒状に形成され、該保持部に前記光ケーブルの引込線を挿通するようにして構成される。
【０００７】
また、配電線用引込線または該配電線用引込線の引留碍子用フックに掛止するための掛止部と光ケーブルの引込線を保持する保持部とを備え、該保持部は帯板を螺旋状に巻回すると共に光ケーブルの許容曲げ半径以上の範囲で曲がる筒状に形成され、該保持部に前記光ケーブルの引込線を挿通するようにして構成される。
【０００８】
また、配電線用引込線または該配電線用引込線の引留碍子用フックに掛止するための掛止部と光ケーブルの引込線を保持する保持部とを備え、該保持部は帯板を光ケーブルの許容曲げ半径以上の範囲で曲げると共にその両端部に光ケーブルの引込線を差込む挟着部を設け、光ケーブルの引込線を保持部に沿わせるようにして配置しかつ両狭着部に差し込むようにて構成される。
【０００９】
また、配電線用引込線または該配電線用引込線の引留碍子用フックに掛止するための掛止部と光ケーブルの引込線を保持する保持部とを備え、該保持部は雄型部材と雌型部材とからなり、前記雄型部材は外周面が先端に向かって窄まる挿入部を有すると共にその軸線に沿って光ケーブルの引込線を挿通する挿通孔が貫設され、また該雄型部材はその外周一側にその長手方向全体に亘り前記挿通孔と連通する差込溝が開設され、一方、前記雌型部材は内周面が先端に向かって窄まり前記挿入部が嵌合される挿入孔を有し、また該雌型部材の外周一側にその長手方向全体に亘り前記挿入孔と連通する差込溝が開設され、前記挿入部を挿入孔に嵌合して前記挿通孔の内径を狭めることにより光ケーブルの引込線を狭着するようにして構成される。
【００１０】
【発明の実施形態】
以下、本発明に係る光ケーブルの引込線の実施の形態を図面に基づき説明する。図１、図２は第一実施の形態に係るもので、この光ケーブルの保持具Ａ１は図１に示すように金属製の線材を屈曲して形成され、長杆部１の上端部を屈曲すると共にその先端部１ａを長杆部１に当接してほぼ直角に折り曲げ環状の掛止部２を設け、また前記長杆部１の下端部を一重半程度に巻回して後記する光ケーブルの引込線Ｋが保持できる保持部３を設けて形成される。この光ケーブルの保持具Ａ１はその線材の表面にナイロンコーティングを施すことが好ましい。これにより長期に使用に十分耐え、耐用年数が伸びる。また、光ケーブルのズレ防止効果も有る。
【００１１】
第一実施の形態の光ケーブルの保持具Ａ１は上記構成よりなる。図２はその使用状態を示すもので、図中、Ｅは配電線用引込線であり、引留碍子Ｇに巻回され建物Ｈ側に引込まれる。引留碍子Ｇは引留碍子用フックＦが取着され、該引留碍子用フックＦを建物Ｈ側に係留することにより支持される。これらは既存の設備である。そこで、光ケーブルの引込線Ｋを前記保持部３に挿通し、この状態で先端部１ａを開きそこから引留碍子用フックＦを掛止部２内に挿通させる。なお、光ケーブルの引込線Ｋの余長部は建物Ｈの外壁面等に取り付けられる接続部収納用キャビネット（図示せず。）に収容される。これにより、光ケーブルの引込線Ｋが配電線用引込線Ｅに沿って保持される。このように既存の設備に簡単に取り付けられ、しかも、光ケーブルの引込線Ｋはズレることなくしっかりと保持され大きく撓むことが無い。よって、光ケーブルの引込線Ｋは配電線用引込線Ｅに沿って大きく撓むことなく保持されることから風圧の影響もあまり受けることがなく、その破損も防止される。
【００１２】
図３乃至図５は第二実施の形態に係るもので、この光ケーブルの保持具Ａ２は図３に示すように第一実施の形態とその保持部の構造が相違するのみであるので、共通する部分は同一符号を附して詳しい説明は省略する。この保持部４は合成樹脂材により形成され、光ケーブルの引込線Ｋが介挿し得る幅を有した平行な一対の上下壁５ａ，５ｂとその一側に設けられた垂直壁６とにより断面コ字状をなしている。また、前記上壁５ａ内側面にこれと対向する下壁５ｂ内側面側へ付勢される弾力舌片７が設けらる。該弾力舌片７は垂直壁６に沿って平行に延設され先端を自由端としている。そして、図４に示すように光ケーブルの引込線Ｋを前記両壁５ａ，５ｂ間に介挿した状態では、該光ケーブルの引込線Ｋが弾力舌片７と下壁５ｂ内側面とで挟着され保持される。この場合、弾力舌片７が光ケーブルの引込線Ｋの表面に面として圧接するので、該光ケーブルの引込線Ｋに集中した過度の圧力が加わるようなことがない。しかも、弾力舌片７は逃げるように作用するので光ケーブルの引込線Ｋは弾力舌片７の延出方向には摺動し易いが、逆の方向には弾力舌片７が圧接して摺動しにくくしている。前記下壁５ｂの開放側にはその端縁に垂直壁６と平行な立ち壁８が突設されている。これは前記両壁５ａ，５ｂ間に介挿された光ケーブルの引込線Ｋがそこから外れにくくするためである。
【００１３】
第二実施の形態に係る光ケーブルの保持具Ａ２は上記構成よりなり、弾力舌片７の先端が引留碍子Ｇと反対側に向くようにして、保持部４に光ケーブルの引込線Ｋを介挿し、更にこの状態で、図５に示すように先端部１ａを開きそこから引留碍子用フックＦを掛止部２内に挿通させる。これにより、光ケーブルの引込線Ｋが配電線用引込線Ｅに沿って保持される。この光ケーブルの引込線Ａ２にあっては、前記弾力舌片７が合成樹脂材からなることから、光ケーブルの引込線Ａ２を介挿した後に、摺動させて送り込むことが可能であり扱いやすい。また、引留碍子用フックＦを掛止部２内に挿通させた後に光ケーブルの引込線Ｋを保持部４に介挿するようにしてもよく、このようにすれば光ケーブルの引込線Ｋが容易に保持できる。なお、光ケーブルの許容曲げ半径以上の範囲で保持すべきときは、配電線用引込線Ｅに光ケーブルの保持具Ａ２をもう一個取り付けるようにする。
【００１４】
図６，図７は第三実施の形態に係るもので、この光ケーブルの保持具Ａ３は図６に示すように金属製の線材を屈曲して形成され、上端部９を円弧状に形成すると共にその両側から所定の間隔離して平行に一対の支持杆部１０ａ，１０ｂを下方に延設して掛止部１１が形成される。各支持杆部１０ａ，１０ｂの下端部は一部接触するようにしてそれぞれ逆方向にコイル状に巻回され、筒状かつ互いに連通する挿通部１２ａ，１２ｂが延設される。これにより、光ケーブルの引込線Ｋが挿通され保持される保持部１３が形成される。各挿通部１２ａ，１２ｂは光ケーブルの許容曲げ半径以上の範囲でへの字状に曲げられている。この場合も光ケーブルの保持具Ａ３はその線材の表面にナイロンコーティングを施すことが好ましい。
【００１５】
第三実施の形態に係る光ケーブルの保持具Ａ３は上記構成よりなり、図７に示すように前記各支持杆部１０ａ，１０ｂの下端部を開きそこから引留碍子用フックＦを掛止部１１内に挿通させる。そして、前記挿通部１２ａ，１２ｂの一端から光ケーブルの引込線Ｋを挿通し送り込んでゆく。これにより、光ケーブルの引込線Ｋが配電線用引込線Ｅに沿って保持される。
【００１６】
図８，図９は第四実施の形態に係るものでこの光ケーブルの保持具Ａ４は、図８に示すように、金属製の平板の上端と下端とを互いに逆向きに湾曲してそれぞれ係止部１４と握持部１５とを備えた掛止部１６と、比較的柔軟な合成樹脂材からなり帯板１８を螺旋状に巻回すると共に光ケーブルの引込線Ｋの許容曲げ半径以上の範囲で曲げた筒状に形成される保持部１７とからなり、該保持部１７のほぼ中央部を前記握持部１５内に嵌入して固定して構成される。平板の一端は前記係止部１４の先端部内側面に開閉自在に当接しており、挿通される引留碍子用フックＦが外れないようにしている。そして、この場合、保持部１７が比較的柔軟な合成樹脂材からなることからよく撓み、挿通された光ケーブルの引込線Ｋの撓みにもよく追随して光ケーブルに集中的な応力が加わることをなくし破損を防止している。
【００１７】
第四実施の形態に係る光ケーブルの保持具Ａ４は上記構成よりなり、まず、前記帯板１８を光ケーブルの引込線Ｋに螺旋状に巻回して保持部１７に光ケーブルの引込線Ｋを挿通する。そして、平板の上部を開いて掛止部１６下端の握持部１５に保持部１７を固定し、また、上端の係止部１４を引留碍子用フックＦに係止する。これにより、光ケーブルの引込線Ｋが配電線用引込線Ｅに沿って保持される。
【００１８】
図１０，図１１は第五実施の形態に係るものでこの光ケーブルの保持具Ａ５は、図１０に示すように金属製からなり、第一実施の形態のように線材からなる長杆部１９の上端部を屈曲すると共にその先端部１９ａを長杆部１９に当接してほぼ直角に折り曲げ環状の掛止部２０が設けられ、前記長杆部１９の下端に保持部２１が一体に設けられている。該保持部２１は帯板２２を全体に長手方向に沿って捻ると共に光ケーブルの許容曲げ半径以上の範囲で弧状に湾曲されており、その両端部に光ケーブルの引込線Ｋを差込む挟着部２３が設けられている。光ケーブルの引込線Ｋは保持部２１における捻られた帯板２２面に添わせて湾曲した状態で各挟着部２３に差し込まれるので、光ケーブルの引込線Ｋには無理な応力が加わらずこれにより破損が防止される。
【００１９】
第五実施の形態に係る光ケーブルの保持具Ａ５は上記構成よりなり、まず先端部１９ａを開きそこから引留碍子用フックＦを掛止部２０内に挿通させる。そして、光ケーブルの引込線Ｋを保持部２１における捻られた帯板２２面に添わせて湾曲させ保持部２１両端の挟着部２３にそれぞれ差し込む。これにより、光ケーブルの引込線Ｋが配電線用引込線Ｅに沿って保持される。
【００２０】
図１２乃至図１４は第六実施の形態に係るものでこの光ケーブルの保持具Ａ６は、図１２に示すように雄型部材２４と該雄型部材２４が嵌脱自在に嵌合する雌型部材２５とからなる合成樹脂製の保持部２６を備え、前記雄型部材２４の外周面に金属製の線材からなり中央部を円弧状に折り曲げ両端部を回動自在に軸挿すると共にその一部を切断断して重ね合わせ部２７ａを設けた環状の掛止部２７を設けてなる。
【００２１】
前記雄型部材２４は、外周面が先端に向かって窄まると共に該外周面に螺子２８ａが刻設された挿入部２９を有し、その基端部には太径の把持部３０が一体に設けられる。該把持部３０は前記挿入部２９の先端側が開口された円筒状に形成される。そして、雄型部材２４の長手方向の軸心に沿って光ケーブルの引込線Ｋが挿通される挿通孔３１が貫設され、また把持部３０を含め挿入部２９の外周一側にその長手方向全体に亘り前記挿通孔３１と連通する差込溝３２が開設される。この雄型部材２４は弾性を有し、外周面に外力が加えられると前記差込溝３２の隙間分外径が小さくなるようになっている。
【００２２】
一方、前記雌型部材２５は、前記把持部３０と同じ外径の円柱状をなし、長手方向の軸心に沿って内周面が先端に向かって窄まると共にその内周面に螺子２８ｂを刻設し前記挿入部２９が螺合して嵌合される挿入孔３３を有し、また、外周一側にその長手方向全体に亘り前記挿入孔３３と連通する差込溝３４が開設されている。また、この雌型部材２５の基端側外周面に細径部３５が設けられ、該細径部３５に前記把持部３０が嵌着されることとなる。
【００２３】
第六実施の形態に係る光ケーブルの保持具Ａ６は上記構成よりなり、互いの差込溝３２，３４から挿通孔３１及び挿入孔３３内に光ケーブルの引込線Ｋを挿通させ、この状態で挿入部２９を挿入孔３３に螺合して嵌合させ、雄型部材２４と雌型部材２５を組み付ける。これにより挿入部２９が締められて細径になり挿通孔３１内の光ケーブルの引込線Ｋを挟着して固定する。そして、重ね合わせ部２７ａを開いて前記掛止部２７内に引留碍子用フックＦを挿通させる。これにより、光ケーブルの引込線Ｋが配電線用引込線Ｅに沿って保持される。前記差込溝３２，３４は直線状に設けたが、他に蛇行させるようにしても良い。これにより両差込溝３２，３４が仮に一致した場合であっても光ケーブルの引込線Ｋがそこから外れ難い。
【００２４】
このように、いずれの実施の形態の光ケーブルの保持具Ａ１〜Ａ６であっても、光ケーブルの引込線Ｋまたは配電線用引込線Ｅに簡単に取り付けられる。なお、各光ケーブルの保持具Ａ１〜Ａ６を引留碍子用フックＦに掛止するようにしたが、配電線用引込線Ｅに掛止するようにしても良い。
【００２５】
【発明の効果】
以上説明したように本発明に係る光ケーブルの保持具は、配電線用引込線または引留碍子用フックに掛止して光ケーブルの引込線を保持できるので、既存の設備を利用して取り付けられ、新たに光ケーブルの引込線を保持するポールを設置するなどの必要がなく、これにより従来のような外壁に掛止金具を固定するなど需要者に余分な負担を掛けずに済む。
【００２６】
また、光ケーブルの引込線を配電線用引込線にほぼ沿わせて配設できるので、風などの影響も受けにくくしてケーブルの破損も防止でき、更には配電線用引込線または引留碍子用フックに簡単に掛止できることから工事に多くの手間や時間がかからず作業能率が向上する。
【００２７】
更に、構造が簡単であって成形が容易であることから、製作コストが低廉になし得るという効果がある。

[0010]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of an optical cable lead-in wire according to the present invention will be described with reference to the drawings. 1 and 2 relate to the first embodiment, and the optical cable holder A1 is formed by bending a metal wire as shown in FIG. 1, and bending the upper end portion of the eaves portion 1. FIG. At the same time, the front end portion 1a is brought into contact with the long eave portion 1 to be bent at a substantially right angle, and an annular hooking portion 2 is provided. Is formed by providing a holding portion 3 that can hold the. The optical cable holder A1 preferably has a nylon coating on the surface of the wire. This will withstand long-term use and increase the service life. In addition, there is an effect of preventing the optical cable from shifting.
[0011]
The optical cable holder A1 of the first embodiment has the above-described configuration. FIG. 2 shows the state of use. In the figure, E is a lead-in wire for distribution lines, wound around a retaining insulator G and drawn into the building H side. The retention insulator G is supported by attaching a retention insulator hook F and mooring the retention insulator hook F to the building H side. These are existing facilities. Therefore, the lead-in wire K of the optical cable is inserted into the holding portion 3, and in this state, the tip end portion 1 a is opened, and the retaining lever hook F is inserted into the latching portion 2 from there. In addition, the extra length part of the lead-in line K of an optical cable is accommodated in the connection part storage cabinet (not shown) attached to the outer wall surface etc. of the building H. Thereby, the lead-in line K of an optical cable is hold | maintained along the lead-in line E for distribution lines. In this way, it can be easily attached to existing equipment, and the optical cable lead-in line K is firmly held without shifting and does not bend greatly. Therefore, since the lead-in wire K of the optical cable is held along the distribution-wire lead-in wire E without being greatly bent, it is not significantly affected by the wind pressure and is prevented from being damaged.
[0012]
FIGS. 3 to 5 relate to the second embodiment, and the optical cable holder A2 is common in that the structure of the holding portion is different from that of the first embodiment as shown in FIG. Parts are denoted by the same reference numerals, and detailed description thereof is omitted. The holding portion 4 is formed of a synthetic resin material, and has a U-shaped cross section by a pair of parallel upper and lower walls 5a and 5b having a width that can be inserted by a lead-in line K of the optical cable and a vertical wall 6 provided on one side thereof. I am doing. Further, an elastic tongue piece 7 is provided on the inner side surface of the upper wall 5a so as to be biased toward the inner side surface of the lower wall 5b opposite to the upper wall 5a. The elastic tongue piece 7 extends in parallel along the vertical wall 6 and has a free end at the tip. As shown in FIG. 4, when the optical cable lead-in line K is interposed between the walls 5a and 5b, the optical cable lead-in line K is sandwiched and held between the elastic tongue 7 and the inner surface of the lower wall 5b. The In this case, since the resilient tongue 7 is pressed against the surface of the optical cable lead-in line K as a surface, excessive pressure concentrated on the optical cable lead-in line K is not applied. In addition, since the elastic tongue 7 acts so as to escape, the optical cable lead-in line K is easy to slide in the extending direction of the elastic tongue 7, but the elastic tongue 7 is pressed against and slides in the opposite direction. It is difficult. On the open side of the lower wall 5b, a standing wall 8 parallel to the vertical wall 6 is projected at the end edge. This is to make it difficult for the lead-in line K of the optical cable inserted between the walls 5a and 5b to come off from there.
[0013]
The optical cable holder A2 according to the second embodiment has the above-described configuration, and the optical cable lead-in line K is inserted into the holding portion 4 so that the tip of the elastic tongue piece 7 faces the side opposite to the retaining lever G. In this state, as shown in FIG. 5, the distal end portion 1 a is opened, and the retaining lever hook F is inserted into the hook portion 2 from there. Thereby, the lead-in line K of an optical cable is hold | maintained along the lead-in line E for distribution lines. In the optical cable lead-in wire A2, the elastic tongue piece 7 is made of a synthetic resin material. Therefore, after the optical cable lead-in wire A2 is inserted, the optical cable lead-in wire A2 can be slid and fed. Further, the optical cable lead-in line K may be inserted into the holding part 4 after the retaining insulator hook F is inserted into the hooking part 2, and in this way, the optical cable lead-in line K can be easily held. . In addition, when it should hold | maintain in the range beyond the permissible bending radius of an optical cable, it is made to attach another holder A2 of an optical cable to the lead-in wire E for distribution lines.
[0014]
FIGS. 6 and 7 relate to the third embodiment. The optical cable holder A3 is formed by bending a metal wire as shown in FIG. 6, and the upper end 9 is formed in an arc shape. The latching portion 11 is formed by extending a pair of support flanges 10a, 10b downwardly in parallel with each other at a predetermined interval from both sides. The lower end portions of the support flanges 10a and 10b are wound in a coil shape in the opposite directions so as to partially contact each other, and the insertion portions 12a and 12b that are tubular and communicate with each other are extended.
