Description
【０００１】[0001]
この考案は、テンションメンバを端末に有する光ファイバケーブル（以下「光 ケーブル」という。）を管路に布設する際に用いるものであり、詳しくは、光ケ ーブルの端末を気密化して牽引に適した状態とするための光ケーブル牽引用端末 具（以下「端末具」という。）に関する。 This invention is used for laying an optical fiber cable having a tension member at a terminal (hereinafter referred to as “optical cable”) in a pipe line. Specifically, it is suitable for towing an optical cable terminal by hermetically sealing it. The present invention relates to a terminal device for pulling an optical cable (hereinafter, referred to as "terminal device") to bring the optical cable into a closed state.
【０００２】[0002]
図４は、従来の端末具を示す一部を切り欠いた側面図である。 従来の端末具１００は、光ケーブル１０２の端末にあるテンションメンバ１０ ４を接続する締付スリーブ１０６を一端に有するとともにアイナット１０８等の 掛止手段を螺合する螺合部１１０を他端に有するプーリングボルト１１２と、螺 合部１１０を突出口１１４から突出させて締付スリーブ１０６を収容する外筒ス リーブ１１６とを備えたものである。外筒スリーブ１１６には縮径部１１８が形 成されている。プーリングボルト１１２には、締付スリーブ１０６と螺合部１１ ０との間に、パッキング１２０を介してソケット１２２に当接するフランジ１２ ４が形成されている。 FIG. 4 is a partially cutaway side view showing a conventional terminal device. A conventional terminal device 100 has a tightening sleeve 106 for connecting a tension member 104 at the end of the optical cable 102 at one end, and a screwing portion 110 for screwing a hooking means such as an eye nut 108 at the other end. The bolt 112 and the outer sleeve sleeve 116 that accommodates the tightening sleeve 106 by projecting the screwing portion 110 from the projecting opening 114 are provided. A reduced diameter portion 118 is formed on the outer cylinder sleeve 116. The pooling bolt 112 has a flange 124 formed between the tightening sleeve 106 and the threaded portion 110 so as to contact the socket 122 via the packing 120.
【０００３】 次に、端末具１００の使用方法を説明する。 締付スリーブ１０６内にテンションメンバ１０４を構成する単線を挿入し、締 付スリーブ１０６をかしめてテンションメンバ１０４を接続する。螺合部１１０ を、パッキング１２０及びソケット１２２に挿通させ、外筒スリーブ１１６の内 部から突出口１１４へ挿通させる。続いて、螺合部１１０をナット１２６で螺合 することにより、プーリングボルト１１２を外筒スリーブ１１６に固着させる。 その後、外筒スリーブ１１６の外周をかしめて縮径部１１８を形成することによ り、縮径部１１８が外皮１２８にくい込んで光ケーブル１０２の端末が気密化さ れる。そして、端末具１００に螺合されたアイナット１０８を引っ張ることによ り、光ケーブル１０２が管路に布設される。Next, a method of using the terminal device 100 will be described. A single wire forming the tension member 104 is inserted into the tightening sleeve 106, and the tightening sleeve 106 is caulked to connect the tension member 104. The threaded portion 110 is inserted into the packing 120 and the socket 122, and is inserted into the projecting opening 114 from the inner portion of the outer cylinder sleeve 116. Next, the pooling bolt 112 is fixed to the outer cylinder sleeve 116 by screwing the screwing portion 110 with the nut 126. After that, by crimping the outer circumference of the outer sleeve 116 to form the reduced diameter portion 118, the reduced diameter portion 118 is embedded in the outer skin 128, and the end of the optical cable 102 is made airtight. Then, by pulling the eye nut 108 screwed to the terminal device 100, the optical cable 102 is laid in the conduit.
【０００４】 また、光ケーブルはメタルケーブルに比較して細径である。そのため、空き管 路が無い場合でも、管路に隙間があればその隙間にインナパイプを挿通して光ケ ーブルを布設することができる。この場合、インナパイプの内径は小さいので、 端末具の外径も小さいことが望まれている。なお、端末具の外径は、外筒スリー ブの外径で決まるものである。Further, the optical cable has a smaller diameter than the metal cable. Therefore, even if there is no empty pipeline, if there is a gap in the pipeline, the inner pipe can be inserted into the gap to install the optical cable. In this case, since the inner diameter of the inner pipe is small, it is desired that the outer diameter of the terminal device is also small. The outer diameter of the terminal device is determined by the outer diameter of the outer sleeve.
【０００５】[0005]
しかしながら、従来の端末具１００では、次のような問題があった。 外筒スリーブ１１６の外周をかしめて縮径部１１８を形成することから、気密 を保持するための一定の強度（例えば、外皮１２８に押し戻されないような強度 ）が縮径部１１８に必要であった。この強度を外筒スリーブ１１６の厚さｔ3 に よって得ているので、外筒スリーブ１１６の外径Ｄ3 を小さくするには限界があ った。したがって、端末具１００の外径Ｄ3 が大き過ぎて光ケーブル１０２を管 路に布設できない場合があった。 突出口１１４側の気密を保つために、パッキング１２０、ソケット１２２、ナ ット１２６等が必要であり。そのため、端末具１００の構成部品数が多く、小型 化、軽量化、組み立ての容易化等の妨げとなっていた。 そこで、この考案の目的は、外径の縮小化及び構成部品数の削減を可能にした 端末具を提供することにある。However, the conventional terminal device 100 has the following problems. Since the reduced diameter portion 118 is formed by caulking the outer circumference of the outer sleeve 116, the reduced diameter portion 118 needs to have a certain strength for maintaining airtightness (for example, the strength so as not to be pushed back by the outer skin 128). It was Since this strength is obtained by the thickness t 3 of the outer cylinder sleeve 116, there is a limit in reducing the outer diameter D 3 of the outer cylinder sleeve 116. Therefore, the outer diameter D 3 of the terminal device 100 may be too large to lay the optical cable 102 in the conduit. The packing 120, the socket 122, the nut 126, and the like are required to maintain the airtightness on the side of the protrusion 114. Therefore, the number of components of the terminal device 100 is large, which hinders downsizing, weight reduction, and easy assembly. Therefore, an object of the present invention is to provide a terminal device capable of reducing the outer diameter and the number of constituent parts.

この考案に係る端末具は、掛止手段を螺合する螺合部が棒状部材の先端側に形 成され、光ケーブル端末の外皮を挿入する大径挿入口が上記棒状部材の基端に形 成され、上記外皮を螺合する雌ねじ部を有する大径スリーブが上記大径挿入口か ら上記棒状部材の内部へ形成され、上記光ケーブル端末のテンションメンバを挿 入する小径挿入口が上記大径スリーブの最深部に形成され、上記テンションメン バを接続する小径スリーブが上記小径挿入口から上記棒状部材の内部へ形成され てなるものである。また、上記棒状部材を周方向に回転可能とする六角部が上記 棒状部材の外周に形成されてなるものとしてもよい。 In the terminal device according to the present invention, the screwing portion for screwing the hooking means is formed on the tip side of the rod-shaped member, and the large-diameter insertion port for inserting the outer sheath of the optical cable terminal is formed on the base end of the rod-shaped member. And a large-diameter sleeve having a female thread portion for screwing the outer cover is formed from the large-diameter insertion opening to the inside of the rod-shaped member, and the small-diameter insertion opening for inserting the tension member of the optical cable terminal is the large-diameter sleeve. A small-diameter sleeve that is formed at the deepest part and connects the tension member is formed inside the rod-shaped member from the small-diameter insertion port. Further, a hexagonal portion that allows the rod-shaped member to rotate in the circumferential direction may be formed on the outer periphery of the rod-shaped member.
【０００７】[0007]
小径挿入口から小径スリーブへテンションメンバを挿入すると、大径挿入口に 外皮が当接する。外皮は適度に弾性を有する合成樹脂で形成されている。そのた め、大径スリーブ内へ外皮を押圧しながら、棒状部材を周方向に回転させると、 雌ねじ部に外皮が螺合される。これにより、光ケーブル端末が気密化される。こ のとき、六角部が形成されていれば、六角部をスパナ等で回転させることにより 作業が容易になる。そして、螺合部に掛止手段を螺合させて、掛止手段を引っ張 ることにより光ケーブルが布設される。 When the tension member is inserted from the small diameter insertion port into the small diameter sleeve, the outer cover contacts the large diameter insertion port. The outer skin is made of a synthetic resin having an appropriate elasticity. Therefore, when the rod-shaped member is rotated in the circumferential direction while pressing the outer cover into the large-diameter sleeve, the outer cover is screwed into the female thread portion. As a result, the optical cable terminal is made airtight. At this time, if the hexagonal part is formed, the work becomes easier by rotating the hexagonal part with a spanner or the like. Then, the hooking means is screwed into the screwing portion, and the hooking means is pulled to lay the optical cable.

図１乃至図３はこの考案に係る端末具の一実施例を示し、図１は一部を切り欠 いた側面図、図２は分解斜視図、図３は雌ねじ部の拡大断面図である。以下、こ れらの図面に基づき詳しく説明する。 1 to 3 show an embodiment of a terminal device according to the present invention, FIG. 1 is a partially cutaway side view, FIG. 2 is an exploded perspective view, and FIG. 3 is an enlarged cross-sectional view of an internal thread portion. A detailed description will be given below with reference to these drawings.
【０００９】 この考案に係る端末具１０は、アイナット１２等の掛止手段を螺合する螺合部 １４が棒状部材１６の先端側に形成され、光ケーブル１０２の端末の外皮１２８ を挿入する大径挿入口１８が棒状部材１６の基端に形成され、外皮１２８を螺合 する雌ねじ部２０を有する大径スリーブ２２が大径挿入口１８から棒状部材１６ の内部へ形成され、光ケーブル１０２の端末のテンションメンバ１０４を挿入す る小径挿入口２４が大径スリーブ２２の最深部２６に形成され、テンションメン バ１０４を接続する小径スリーブ２８が小径挿入口２４から棒状部材１６の内部 へ形成されてなるものである。また、棒状部材１６を周方向に回転可能とする六 角部３０が棒状部材１６の外周に形成されている。In the terminal device 10 according to the present invention, the screwing portion 14 for screwing the hooking means such as the eye nut 12 is formed on the tip end side of the rod-shaped member 16 and has a large diameter for inserting the outer cover 128 of the end of the optical cable 102. An insertion port 18 is formed at the proximal end of the rod-shaped member 16, and a large-diameter sleeve 22 having an internal thread portion 20 for screwing an outer cover 128 is formed from the large-diameter insertion port 18 to the inside of the rod-shaped member 16 to connect the end of the optical cable 102. A small-diameter insertion port 24 for inserting the tension member 104 is formed in the deepest portion 26 of the large-diameter sleeve 22, and a small-diameter sleeve 28 for connecting the tension member 104 is formed from the small-diameter insertion port 24 to the inside of the rod-shaped member 16. It is a thing. Further, a hexagonal portion 30 that allows the rod-shaped member 16 to rotate in the circumferential direction is formed on the outer periphery of the rod-shaped member 16.
【００１０】 棒状部材１６は、鉄等を切削して、雄ねじからなる螺合部１４を先端側に、軸 方向へ穿設された大径スリーブ２２及び小径スリーブ２８を基端側にそれぞれ形 成したものである。棒状部材１６の中央付近には六角部３０が形成されている。 棒状部材１６の最大外径は大径スリーブ２２の外径Ｄ1 である。外径Ｄ1 が端末 具１０に外径となる。The rod-shaped member 16 is formed by cutting iron or the like to form a male threaded portion 14 on the tip side and a large-diameter sleeve 22 and a small-diameter sleeve 28 bored in the axial direction on the proximal side. It was done. A hexagonal portion 30 is formed near the center of the rod member 16. The maximum outer diameter of the rod-shaped member 16 is the outer diameter D 1 of the large-diameter sleeve 22. The outer diameter D 1 is the outer diameter of the terminal device 10.
【００１１】 大径スリーブ２２内の大径挿入口１８から最深部２６までには雌ねじ部２０が 形成されている。最深部２６には外皮１２８が当接する。大径スリーブ２２の内 径Ｄ2 は、図３に示すねじ山３８の谷の部分を測定したものであり、外皮１２８ の外径と同一にしてある。また、小径スリーブ２８には、テンションメンバ１０ ４を接続するためのかしめ部４０、４０が形成されている。A female screw portion 20 is formed in the large-diameter sleeve 22 from the large-diameter insertion opening 18 to the deepest portion 26. The outer skin 128 contacts the deepest portion 26. The inner diameter D 2 of the large-diameter sleeve 22 is obtained by measuring the valley portion of the screw thread 38 shown in FIG. 3, and is the same as the outer diameter of the outer cover 128. Further, the small-diameter sleeve 28 is provided with caulking portions 40, 40 for connecting the tension member 104.
【００１２】 次に、端末具１０の使用方法を説明する。 小径挿入口２４から小径スリーブ２８へテンションメンバ１０４を挿入すると 、大径挿入口１８に外皮１２８が当接する。外皮１２８は適度に弾性を有する合 成樹脂で形成されている。そのため、大径スリーブ２２内へ外皮１２８を押圧し ながら、棒状部材１６を周方向に回転させると、雌ねじ部２０に外皮１２８が螺 合される。これにより、光ケーブル１０２の端末が気密化される。このとき、六 角部３０が形成されていれば、六角部３０をスパナ等で回転させることにより作 業性が向上する。続いて、小径スリーブ２８を工具でかしめてかしめ部４０、４ ０を形成し、小径スリーブ２８にテンションメンバ１０４を接続する。そして、 螺合部１４にアイナット１２を螺合させて、アイナット１２を引っ張ることによ り光ケーブル１０２が布設される。Next, a method of using the terminal device 10 will be described. When the tension member 104 is inserted into the small diameter sleeve 28 from the small diameter insertion port 24, the outer cover 128 contacts the large diameter insertion port 18. The outer cover 128 is made of synthetic resin having appropriate elasticity. Therefore, when the rod-shaped member 16 is rotated in the circumferential direction while pressing the outer cover 128 into the large-diameter sleeve 22, the outer cover 128 is screwed into the female screw portion 20. As a result, the terminal of the optical cable 102 is made airtight. At this time, if the hexagonal portion 30 is formed, the workability is improved by rotating the hexagonal portion 30 with a spanner or the like. Subsequently, the small diameter sleeve 28 is crimped with a tool to form the crimped portions 40, 40, and the tension member 104 is connected to the small diameter sleeve 28. Then, the eye nut 12 is screwed into the screwing portion 14, and the optical fiber 102 is laid by pulling the eye nut 12.
【００１３】 図４に示す縮径部１１８は、外皮１２８に対して円状の線接触により外皮１２ ８を気密化している。これに対し、雌ねじ部２０は、多数のねじ山３８からなる 円筒状の面接触により外皮１２８を気密化している。すなわち、雌ねじ部２０は 縮径部１１８に比べて気密性が優れている。また、外皮１２８の揺動等の外力に 対しては、縮径部１１８は線接触であるために応力が集中しやすいが、雌ねじ部 ２０は面接触であるため応力が分散しやすい。このような理由により、大径スリ ーブ２２は、外筒スリーブ１１６に比べて、気密性を保持したままその厚さｔ1 を薄くできる。The reduced diameter portion 118 shown in FIG. 4 makes the outer skin 128 airtight by circular line contact with the outer skin 128. On the other hand, the female threaded portion 20 hermetically seals the outer skin 128 by a cylindrical surface contact consisting of a large number of threads 38. That is, the female threaded portion 20 is more airtight than the reduced diameter portion 118. Further, with respect to an external force such as rocking of the outer cover 128, stress is likely to be concentrated in the reduced diameter portion 118 due to the line contact, but stress is likely to be dispersed in the female screw portion 20 due to the surface contact. For this reason, large-diameter Sri chromatography Bed 22, compared to the outer cylinder sleeve 116, can be reduced its thickness t 1 while maintaining the airtightness.
【００１４】 端末具１０では、光ケーブル１０２の端末を気密化するのに、図４に示す外筒 スリーブ１１６の代わりに大径スリーブ２２を用いている。そのため、大径スリ ーブ２２の厚さをｔ1 とすると、端末具１０の外径Ｄ1 は、従来の端末具１００ の外径Ｄ3 よりも２（ｔ3 −ｔ1 ）だけ小さくなる。In the terminal device 10, a large-diameter sleeve 22 is used in place of the outer sleeve 116 shown in FIG. 4 to hermetically seal the end of the optical cable 102. Therefore, when the thickness of the large diameter sleeve 22 is t 1 , the outer diameter D 1 of the terminal device 10 is smaller than the outer diameter D 3 of the conventional terminal device 100 by 2 (t 3 −t 1 ). .
【００１５】 具体的な数値例を示せば、外筒スリーブ１１６の厚さｔ3 が１〜１．５ｍｍで あるのに対し、大径スリーブ２２の厚さｔ1 が０．５ｍｍ以下にできる。また、 図３に示すねじ山３８は、角度θが６０°、ピッチＰが１ｍｍである。さらに、 図２に示す雌ねじ部２０の長さＬは８ｍｍである。As a specific numerical example, the thickness t 3 of the outer cylinder sleeve 116 is 1 to 1.5 mm, while the thickness t 1 of the large-diameter sleeve 22 can be 0.5 mm or less. The thread 38 shown in FIG. 3 has an angle θ of 60 ° and a pitch P of 1 mm. Further, the length L of the female screw portion 20 shown in FIG. 2 is 8 mm.
【００１６】 また、端末具１０によれば、大径スリーブ２２だけで充分な気密化が達成でき るので、図４における外筒スリーブ１１６、パッキング１２０、ソケット１２２ 、ナット１２６等を不要にでき、構成部品数を削減できる。したがって、極めて 安価な端末具１０を提供でき、端末具１０の使い捨ても可能である。Further, according to the terminal device 10, since sufficient airtightness can be achieved only by the large-diameter sleeve 22, the outer sleeve sleeve 116, the packing 120, the socket 122, the nut 126 and the like in FIG. 4 can be eliminated, The number of components can be reduced. Therefore, the extremely inexpensive terminal device 10 can be provided, and the terminal device 10 can be disposable.
【００１７】[0017]
請求項１又は２記載の端末具によれば、大径スリーブの雌ねじ部に外皮を螺合 するだけで簡単に光ケーブ端末を気密化できることから、次の効果を奏する。 大径スリーブの厚さは薄いものであるので、端末具の外径を縮小化でき、管路 の小さな隙間にも光ケーブルを布設できる。 外筒スリーブ、パッキング等を不要にできるので、構成部品数の削減により、 小型化、軽量化、組み立ての容易化等を達成できる。 According to the terminal device of the first or second aspect, the optical cable terminal can be easily hermetically sealed by simply screwing the outer skin onto the female thread portion of the large-diameter sleeve. Since the large-diameter sleeve is thin, the outer diameter of the terminal device can be reduced, and the optical cable can be laid in a small gap in the conduit. Since it is possible to eliminate the need for an outer sleeve and packing, it is possible to achieve size reduction, weight reduction, and easy assembly by reducing the number of components.
【００１８】 請求項２記載の端末具によれば、六角部をスパナ等で回転させることにより雌 ねじ部に外皮を簡単に螺合でき、作業性を向上できる。According to the terminal device of the second aspect, by rotating the hexagonal portion with a spanner or the like, the outer skin can be easily screwed into the female screw portion, and the workability can be improved.
