【産業上の利用分野】
電柱間にケーブルを架設する際、電柱間に吊架した吊り線（メッセンジャーワイヤー）に螺旋状ケーブル吊り具を吊架せしめ、該螺旋状ケーブル吊り具にケーブルを受支させるようにし、前記螺旋状ケーブル吊り具は順次連結して電柱間のほぼ全域に吊架するようにしているが、本発明は、螺旋状ケーブル吊り具を順次連結する際に用いる連結具に関するものである。
【０００２】
【従来の技術】
例えば、特開平９−７０１２８号公報所載のとおりアルミニウム製の筒体より成る連結具の両端に、互いに連結する螺旋状ケーブル吊り具の端末を嵌挿するようにして構成した構造のものがある。
【０００３】
前記従来例は、基本的に連結具を圧潰して一対の螺旋状ケーブル吊り具を連結して得るものであるが、該圧潰作業が煩雑であるのみならず、連結具よりケーブル吊り具が抜ける方向の外力が負荷したとき容易に抜け易く、連結状態を維持できない等々の欠点がある。
【０００４】
本発明は斯様な従来例の欠点を回避し、斬新な構造の連結具を提供すべく創案したものである。
【０００５】
【課題を解決するための手段】
互いに連結する螺旋状ケーブル吊り具の端末に基部片において固着する合成樹脂製の第一、第二の連結材で成り、前記螺旋状ケーブル吊り具の連結方向に長い係止部と頸部とで成る嵌挿部片を、前記第一連結材の前記基部片に前記頸部において連設し、該嵌挿部片を強制的に嵌挿して係止する筒状部片を前記第二連結材の前記基部片に連設し、該筒状部片の第一連結材の前記基部片に接する開口端側には、前記嵌挿部片より短かく、しかも、前記連結方向に沿う一対のスリットを設けた構成とするのである。
【０００６】
【実施例】
図面は本発明に係る螺旋状ケーブル吊り具の連結の一実施例を示し、図１は一部欠截正面図、図２は図１のｘ−ｘ線断面図、図３は一部欠截分解平面図、図４は使用状態を示す正面図である。
【０００７】
本発明は、鋼線より成る芯材を合成樹脂で被覆して構成した螺旋状ケーブル吊り具１，１´（具体例を挙げるまでもなく公知）を第一、第二の連結材（ポリアセタール樹脂を素材とするが、他の樹脂素材でも良い）２，３で連結する連結具Ａに係り、第一、第二の連結材２，３は、それぞれの基部片４，５に設けた接続穴６，６´に螺旋状ケーブル吊り具（以下、単にケーブル吊り具と称す）１，１´の端末を嵌挿するようにしてケーブル吊り具１に固着して用いる。
【０００８】
この固着作業は、工場で行われ、接続穴６，６´にケーブル吊り具１の端末を嵌挿して、ケーブル吊り具１，１´乃至連結材２，３の弾性変形を利用して固着状態を維持させる場合と、接続穴６，６´に接着剤を注入して接着剤の接着力を利用して固着状態を維持する場合があり、ここで「固着」とは本発明の連結具Ａを用いた連結装置に外力が負荷した際、連結材２，３とケーブル吊り具１とが不測のとき以外は互いに離脱しない状態にあることをいう。
【０００９】
前記第一連結材２は、前記ケーブル吊り具１，１´の連結方向に長い係止部７ａと頸部７ｂとで成る嵌挿部片７を前記基部片４に連設して構成する。
【００１０】
この第一連結材２を構成する前記嵌挿部片７の係止部７ａは、前記頸部７ｂ側の基部を大径にした先細状に構成し、相対する一対の周縁部７ａ´，７ａ´を円弧面状に、該周縁部７ａ´，７ａ´間に存して互いに相対する他の一対の周縁部７ａ´´，７ａ´´を直面状にして形成して、前記第二連結材３の筒状部片８内において回動しないようにしてあり、この係止部７ａと前記基部片４との間に介在する前記頸部７ｂは係止部７ａの大径部に隣接して径を小さくして、前記筒状部片８の内径の狭い開口端部８ａが係合するようにしてある。
【００１１】
なお、頸部７ｂと係止部７ａの中間部に鍔部片９，９を突設してあるが、この鍔部片９は筒状部片８に形成したスリット１０に係合され、位置合わせの目印となり、また、頸部７ｂの補強材として機能すると共に、第一、第二の連結材２，３の結合状態における折れ曲げ方向の外力の負荷に対する補強ともなる。
【００１２】
前記第二連結材２は、前記基部片５に前記筒状部片８を連設して構成し、筒状部片８は内壁８´を、鍔部片９を除いた前記嵌挿部片７の外形とほぼ同形にしてある。
【００１３】
しかして、互いに連結する一方のケーブル吊り具１の端末に第一連結材２を、他の一方のケーブル吊り具１´の端末に第二連結材３をそれぞれ前記のようにして接続固着し、第二連結材３の筒状部片８、一方のケーブル吊り具１に取付けた第一連結材２の嵌挿部片７を、一致させて第一連結材２側を押圧すると、嵌挿部片７は筒状部片８に強制的に圧入され、両連結材２，３の先端面２´，３´が互いに面接触して設定した接触角度を維持して両連結材２，３すなわち一対のケーブル吊り具１，１´は互いに連結され、このとき、前記嵌挿部片７が筒状部片８に圧入される際、筒状部片８の先端部側にスリット１０を設けて、筒状部片８をいわば二又に分岐してあるので、これが弾性変形して嵌挿部片７と筒状部片８との嵌合操作が円滑に行われる。
【００１４】
しかして、一方の電柱から他の電柱位置まで、ケーブル吊り具を前記電柱間に吊架した吊り線ａに巻回して第一連結材２と第二連結材３を互いに連結する操作を繰り返すことにより、電柱間に第一連結材２と第二連結材３を用いて順次連結された適宜数のケーブル吊り具が配され、このケーブル吊り具を挿通するようにしてケーブルＣを前記吊り線ａに沿って移動させることによりケーブルＣは前記電柱間にケーブル吊り具に受支されて吊架される。
【００１５】
そして、このケーブル吊架作業中或いは吊架作業後に、ケーブル吊り具１，１´乃至第一、第二の連結材２，３に外力が負荷しても、嵌挿部片７と筒状部片８の結合関係によりケーブル吊り具１，１´の連結状態は確実に維持される。
【００１７】
【発明の効果】
本発明は前記の通りの構成であるから、嵌挿部片と筒状部片とが成す連結部にケーブル吊り具の半径方向に外力が付加しても嵌挿部片はスリットより長いため、前記折曲げ方向の外力により嵌挿部片が筒状部片より抜けることがなく、また、連結部の連結方向（ケーブル吊り具の軸線方向）に外力が付加されることは殆どないから、筒状部片を強制的に弾性変形させて嵌挿部片を引き抜かない限り、連結状態は維持され、従って、螺旋状ケーブル吊り具同士の連結状態を確実に維持する連結装置を提供できる。そして、必要に際しては、嵌挿部片を筒状部片より離脱させて、前記の連結状態を解消することができる。
【００１８】
ケーブル吊り具同士を連結状態から解消できるから、ケーブル吊り具の再利用のできる連結具を提供できる。

[Industrial application fields]
When laying a cable between utility poles, a spiral cable suspender is suspended on a suspending line (messenger wire) suspended between the utility poles, and the cable is supported by the spiral cable suspender. The cable suspenders are sequentially connected to be suspended over almost the entire area between the utility poles, but the present invention relates to a connector used when the spiral cable suspenders are sequentially connected.
[0002]
[Prior art]
For example, as disclosed in Japanese Patent Application Laid-Open No. 9-70128, there is a structure in which a terminal of a spiral cable suspension connected to each other is fitted to both ends of a connector made of an aluminum cylinder. .
[0003]
The conventional example is basically obtained by crushing a connecting tool and connecting a pair of helical cable hanger, but the crushing operation is not only complicated, but the cable hanger comes out of the connecting tool. When the external force in the direction is applied, there is a drawback that it is easy to come off and the connected state cannot be maintained.
[0004]
The present invention has been devised to avoid such drawbacks of the prior art and to provide a connector having a novel structure.
[0005]
[Means for Solving the Problems]
It consists of first and second connecting members made of synthetic resin that are fixed at the base piece to the ends of the spiral cable suspensions that are connected to each other. A cylindrical piece for connecting and locking the fitting part forcibly by inserting and engaging the fitting part in the neck part to the base piece of the first coupling member. A pair of slits that are shorter than the fitting insertion piece and extend in the connecting direction on the opening end side of the first connecting member of the cylindrical piece that is in contact with the base piece. It is set as the structure which provided.
[0006]
【Example】
The drawings show an embodiment of the connection of the helical cable suspension according to the present invention, FIG. 1 is a partially cutaway front view, FIG. 2 is a sectional view taken along line xx of FIG. 1, and FIG. FIG. 4 is an exploded plan view and FIG. 4 is a front view showing a use state.
[0007]
In the present invention, helical cable suspensions 1 and 1 '(known without mentioning specific examples) formed by coating a core material made of steel wire with a synthetic resin are used as first and second connecting materials (polyacetal resin). The first and second connecting members 2 and 3 are connection holes provided in the base pieces 4 and 5, respectively. 6 and 6 'are used by being fixed to the cable hanger 1 so that the ends of spiral cable hanger (hereinafter simply referred to as cable hanger) 1 and 1' are inserted.
[0008]
This fixing work is performed at the factory, and the end of the cable hanger 1 is inserted into the connection holes 6 and 6 ′, and is fixed using the elastic deformation of the cable hanger 1, 1 ′ to the connecting members 2, 3. In some cases, an adhesive is injected into the connection holes 6 and 6 'and the adhesive state of the adhesive is used to maintain the fixed state. Here, "fixed" means the connector A of the present invention. When an external force is applied to the connecting device using, the connecting members 2 and 3 and the cable suspension 1 are in a state where they are not separated from each other except when unexpected.
[0009]
The first connecting member 2 is configured by connecting a fitting insertion piece 7 composed of a locking portion 7 a and a neck portion 7 b that are long in the connecting direction of the cable suspensions 1, 1 ′ to the base piece 4.
[0010]
The engaging portion 7a of the fitting insertion piece 7 constituting the first connecting member 2 is formed in a tapered shape with the base portion on the neck portion 7b side having a large diameter, and a pair of opposed peripheral edge portions 7a ′ and 7a. ′ Is formed in a circular arc shape, facing the other pair of peripheral edge portions 7a ″, 7a ″ existing between the peripheral edge portions 7a ′, 7a ′, and the second connecting member 3 is prevented from rotating in the cylindrical piece 8, and the neck 7b interposed between the locking portion 7a and the base piece 4 is adjacent to the large diameter portion of the locking portion 7a. The opening end 8a with a narrow inner diameter of the cylindrical piece 8 is engaged with the diameter reduced.
[0011]
In addition, although the collar part 9 and 9 are protrudingly provided in the intermediate part of the neck part 7b and the latching | locking part 7a, this collar part piece 9 is engaged with the slit 10 formed in the cylindrical part piece 8, and position. In addition to functioning as a reinforcing material for the neck portion 7b, it also serves as a reinforcement against the load of external force in the bending direction when the first and second connecting members 2 and 3 are joined.
[0012]
The second connecting member 2 is configured by connecting the cylindrical piece 8 to the base piece 5, and the cylindrical piece 8 is an insertion wall piece except for an inner wall 8 ′ and a flange piece 9. 7 is almost the same shape as the outer shape.
[0013]
Thus, the first connecting member 2 and the second connecting member 3 are fixedly connected to the ends of one of the cable suspensions 1 connected to each other and the other one of the cable suspensions 1 ′ as described above, respectively. When the cylindrical connecting piece 8 of the second connecting member 3 and the fitting inserting piece 7 of the first connecting member 2 attached to one cable suspension 1 are made to coincide and press the first connecting member 2 side, the inserting portion The piece 7 is forcibly press-fitted into the cylindrical piece 8 and maintains the contact angle set by the tip surfaces 2 'and 3' of the connecting members 2 and 3 being in surface contact with each other. The pair of cable suspenders 1 and 1 ′ are connected to each other. At this time, when the fitting piece 7 is press-fitted into the tubular piece 8, a slit 10 is provided on the distal end side of the tubular piece 8. Since the cylindrical piece 8 is bifurcated, it is elastically deformed so that the fitting operation between the fitting insertion piece 7 and the cylindrical piece 8 is performed smoothly. That.
[0014]
Thus, the operation of connecting the first connecting member 2 and the second connecting member 3 to each other by winding the cable hanger around the suspension line a suspended between the utility poles from one utility pole to the other utility pole position is repeated. Thus, an appropriate number of cable suspenders sequentially connected using the first linking material 2 and the second linking material 3 are arranged between the utility poles, and the cable C is connected to the suspending line a so as to pass through the cable suspending device. The cable C is supported and supported by the cable suspension between the power poles.
[0015]
And even if this cable suspension work or after the suspension work, even if an external force is applied to the cable suspensions 1, 1 ′ to the first and second connection members 2, 3, the fitting insertion piece 7 and the tubular part The connection state of the cable suspensions 1 and 1 ′ is reliably maintained by the connection relationship of the pieces 8.
[0017]
【The invention's effect】
Since the present invention is configured as described above, even if an external force is applied in the radial direction of the cable hanger to the connecting portion formed by the fitting insertion piece and the cylindrical piece, the fitting insertion piece is longer than the slit. The external insertion force in the bending direction prevents the fitting insertion piece from coming out of the cylindrical piece, and the external force is hardly applied in the connecting direction of the connecting portion (the axial direction of the cable suspension). Unless the insertion piece is pulled out by forcibly elastically deforming the shape piece, the connection state is maintained. Therefore, it is possible to provide a connection device that reliably maintains the connection state between the helical cable suspensions. And when necessary, the above-mentioned connection state can be canceled by detaching the fitting insertion piece from the cylindrical piece.
[0018]
Since the cable suspenders can be eliminated from the connected state, a connector capable of reusing the cable suspenders can be provided.
