Description

本発明は光ファイバケーブル等の支持線を固定するケーブル支持線固定部材に関する。   The present invention relates to a cable support line fixing member for fixing a support line such as an optical fiber cable.

光ファイバケーブルを各加入者宅に配線するために、ドロップケーブルと呼ばれる光ファイバケーブルが使用されている。図１８に断面図として示すように、ドロップケーブル８０は、１つまたは複数の光ファイバ芯線８３と、光ファイバ芯線８３の両側に配置されたテンションメンバ８４とを内蔵するケーブル部８２と、ケーブル部８２から切り離し可能に設けられた支持線８６とを有する。支持線８６は、典型的には金属や高強度FRP（繊維強化プラスチック）からなる芯線８７が樹脂被覆８８で覆われたものである。例えば、ドロップケーブルの芯線として、許容張力６００Ｎ以上を有するφ１．２ｍｍ鋼線が使用されている。ドロップケーブルの敷設時には、ケーブルを住宅や電柱に対して固定したり、ドロップケーブル同士を直線接続したりする場合がある。このとき、ケーブルに内蔵されている光ファイバを接続すると共に、ケーブル部から支持線を所定長さだけ切り離し、支持線を他の支持線や固定部材に接続する。   In order to wire the optical fiber cable to each subscriber's house, an optical fiber cable called a drop cable is used. As shown in a sectional view in FIG. 18, the drop cable 80 includes a cable portion 82 including one or a plurality of optical fiber core wires 83 and tension members 84 arranged on both sides of the optical fiber core wire 83, and a cable portion. And a support line 86 provided so as to be separable from 82. The support wire 86 is typically a core wire 87 made of metal or high-strength FRP (fiber reinforced plastic) and covered with a resin coating 88. For example, a φ1.2 mm steel wire having an allowable tension of 600 N or more is used as the core wire of the drop cable. When laying a drop cable, the cable may be fixed to a house or a utility pole, or the drop cables may be connected in a straight line. At this time, the optical fiber built in the cable is connected, the support line is cut from the cable part by a predetermined length, and the support line is connected to another support line or a fixing member.

ドロップケーブル同士を直線接続するために、支持線固定具とクロージャースリーブとからなるクロージャーが考案されている（特許文献１）。特許文献１の段落００１５には以下のような記載がある。「支持線固定具５は、支持板１１を備えており、支持板１１の上面には、両端側にそれぞれ配置された支持線押さえ部１２と、２つ配置された突起部１３が突設されている。支持線押さえ部１２は、断面略ひし形に形成された柱状部１２Ａと、その上端側に形成された傘部１２Ｂとから構成されている。また、突起部１３は、断面略楕円形に形成された柱部１３Ａと、その上端側に形成された傘部１３Ｂとから構成されている。」   In order to connect drop cables with each other in a straight line, a closure composed of a support wire fixing tool and a closure sleeve has been devised (Patent Document 1). Paragraph 0015 of Patent Document 1 has the following description. “The support line fixture 5 includes a support plate 11, and on the upper surface of the support plate 11, support line pressing portions 12 disposed on both ends, and two projecting portions 13 are provided. The support wire pressing portion 12 is composed of a columnar portion 12A having a substantially rhombic cross section and an umbrella portion 12B formed on the upper end side thereof, and the protrusion 13 is substantially oval in cross section. It is comprised from the pillar part 13A formed in this, and the umbrella part 13B formed in the upper end side. "

さらに、段落００２０には、「両端側から進入させた支持線３Ａ、３Ｂを突起部１３に巻き付け、進入方向に折り返し、折り返した支持線３Ａ、３Ｂを支持線押え部１２に押さえつけた後、折り返した支持線３Ａ，３Ｂの先端部と、支持線３Ａ、３Ｂとをテープ等により巻き付けて固定する」ことが記載されている。   Further, in paragraph 0020, “the support lines 3A and 3B entered from both ends are wound around the protrusion 13 and folded back in the approach direction, and the folded support lines 3A and 3B are pressed against the support line presser 12 and then folded back. In other words, the front ends of the support wires 3A and 3B and the support wires 3A and 3B are wound and fixed with a tape or the like.

また、ドロップケーブルを住宅に引き込むときには、支持線が住宅の壁面に対して支持線の固定具を介して固定される（例えば特許文献２）。特許文献２の段落０００２には、「図９では、電柱２１上を架空されて来た光ファイバ２４を電柱２１に設けた支持具であるフック金具２５ａと引留金具２５ｂとで一旦支持させた後、家屋２６に引込んでいる。そして、家屋２６の引込み部は軒下等に設けた外壁引留金具２７ａと引留金具２７ｂとで光ファイバ２４を引留め、引込線収納箱２８を設置して余長分を収納した後に屋内に引込む」ことが記載されている。   Further, when the drop cable is drawn into the house, the support line is fixed to the wall surface of the house via a support wire fixing tool (for example, Patent Document 2). In paragraph 0002 of Patent Document 2, “In FIG. 9, after the optical fiber 24 that has been suspended over the utility pole 21 is once supported by the hook fitting 25a and the retaining fitting 25b that are supports provided on the utility pole 21. The retracting portion of the house 26 is secured to the optical fiber 24 by the outer wall retaining metal fitting 27a and the retaining metal fitting 27b provided under the eaves, etc. "It is retracted indoors after storage".

ドロップケーブルを直線接続する、あるいは、家屋の壁面に対して固定する場合には、ケーブルを無駄にすることなく接続することが好ましい。支持線はケーブルと一体的に作製されていることが多いため、できるだけ短い支持線の余長で支持線を固定できることが望まれている。また、支持線の固定作業は電柱上や梯子の上等の足場の悪い状況下で行われる場合が多い。そのため、支持線の固定作業は簡潔にできることが望まれている。   When the drop cable is connected in a straight line or fixed to the wall surface of the house, it is preferable to connect the cable without wasting it. Since the support line is often manufactured integrally with the cable, it is desired that the support line can be fixed with a surplus length of the support line as short as possible. In addition, the fixing work of the support line is often performed under poor conditions such as on a utility pole or ladder. Therefore, it is desired that the fixing work of the support line can be simplified.

本発明はその一態様において、短い余長で支持線を容易に固定できるケーブル支持線固定部材を提供する。   In one aspect, the present invention provides a cable support line fixing member capable of easily fixing a support line with a short extra length.

本発明はその一態様において、先端を折り曲げたケーブル支持線を挿入し、固定するケーブル支持線固定部材であって、主壁と、主壁から立ち上がって延出する、対向して配置された２つの側壁と、少なくとも一方の側壁から立ち上がって他方の側壁に近づく方向に延出する副壁と、主壁と側壁と副壁とで概略画定される支持線受容部と、ケーブル支持線を支持線受容部に挿入したときに、ケーブル支持線の先端部を係止する係止部と、を有し、係止部は、ケーブル支持線の端面に当接することにより先端部を係止する、ケーブル支持線固定部材を提供する。 In one aspect, the present invention is a cable support line fixing member that inserts and fixes a cable support line having a bent tip, and is arranged to face and extend from the main wall and rise from the main wall. One side wall, a sub-wall that rises from at least one side wall and extends in a direction approaching the other side wall, a support line receiving portion that is roughly defined by the main wall, the side wall, and the sub-wall, and a cable support line when inserted into the receiving portion, possess a locking unit for locking the front end portion of the cable support line, the locking portion is to lock the tip by abutting the end face of the cable support wire, cable A support wire fixing member is provided .

本発明の一態様によるケーブル支持線固定部材によれば、短い余長で容易に支持線を固定することができる。   According to the cable support line fixing member according to one aspect of the present invention, the support line can be easily fixed with a short extra length.

本発明の１実施形態によるケーブル支持線固定部材は、支持線を受容して固定する支持線受容部を有する、略長方体の部材である。支持線受容部は、主壁と、主壁の両側から略垂直方向に延出する２つの側壁と、側壁から略垂直に延出する副壁とによって、概略画定されている。ケーブル支持線固定部材は、一つの側壁に隣接して設けられた係止部をさらに有する。支持線は、先端を鉤状に折り曲げた状態でケーブル支持線固定部材に挿入される。支持線の端部がケーブル支持線固定部材の係止部に当接して係止され、支持線がケーブル支持線固定部材に対して固定される。このように本発明の1実施形態によるケーブル支持線固定部材によれば、支持線の先端を折り曲げてケーブル支持線固定部材に挿入するだけで、支持線をケーブル支持線固定部材に対して容易に固定することができる。また、支持線をケーブル支持線固定部材に巻きつける必要がないので、必要とされる支持線の長さも短くできる。   A cable support wire fixing member according to an embodiment of the present invention is a substantially rectangular member having a support wire receiving portion for receiving and fixing a support wire. The support line receiving portion is roughly defined by a main wall, two side walls extending in a substantially vertical direction from both sides of the main wall, and a sub-wall extending in a substantially vertical direction from the side wall. The cable support line fixing member further includes a locking portion provided adjacent to one side wall. The support line is inserted into the cable support line fixing member with the tip bent in a hook shape. The end portion of the support line is brought into contact with and locked with the locking portion of the cable support line fixing member, and the support line is fixed to the cable support line fixing member. As described above, according to the cable support line fixing member according to the embodiment of the present invention, it is possible to easily support the support line with respect to the cable support line fixing member simply by bending the tip of the support line and inserting it into the cable support line fixing member. Can be fixed. Further, since it is not necessary to wind the support wire around the cable support wire fixing member, the length of the support wire required can be shortened.

以下図面を参照しながら、本発明のケーブル支持線固定部材を説明する。図１は本発明の第１の実施形態によるケーブル支持線固定部材１が支持線８６ａ、８６ｂを直線的に固定した状態を示す図であり、図２（ａ）は本発明の一実施形態によるケーブル支持線固定部材１を示す上面図であり、図２（ｂ）は右側面図である。   The cable support line fixing member of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a state in which the cable support line fixing member 1 according to the first embodiment of the present invention linearly fixes the support lines 86a and 86b, and FIG. 2 (a) is according to one embodiment of the present invention. It is a top view which shows the cable support wire fixing member 1, and FIG.2 (b) is a right view.

図１に示すように、ケーブル支持線固定部材１は、内部に支持線受容部１０を有する概略長方体の形状をしている。２つの支持線８６ａ、８６ｂはケーブル支持線固定部材１の長手方向両端部から支持線受容部１０に挿入され、ケーブル支持線固定部材１に対して固定されている。図４に示すように、支持線８６は、先端部８６３と基端部８６１との間で折り曲げられており、折り曲げ部８６２がケーブル支持線固定部材１の中心近傍に配置されている。   As shown in FIG. 1, the cable support line fixing member 1 has a substantially rectangular shape having a support line receiving portion 10 inside. The two support wires 86 a and 86 b are inserted into the support wire receiving portion 10 from both longitudinal ends of the cable support wire fixing member 1 and are fixed to the cable support wire fixing member 1. As shown in FIG. 4, the support line 86 is bent between the distal end portion 863 and the base end portion 861, and the bent portion 862 is disposed in the vicinity of the center of the cable support line fixing member 1.

ケーブル支持線固定部材１は任意の材料から作製することができる。例えば、鉄やステンレス等の金属、各種プラスチック等から作製することができる。図示のケーブル支持線固定部材１は板状の金属を折り曲げ加工して形成されているが、作製方法はこれに限らず公知の作製方法で作製することができる。例えば、押し出し成型により断面が矩形の中空パイプを作製した後に、必要な部分を切削加工することでも作製することができる。また、ケーブル支持線固定部材１は、概略円柱形であっても良い。   The cable support wire fixing member 1 can be made of any material. For example, it can be produced from metals such as iron and stainless steel, various plastics, and the like. The illustrated cable support line fixing member 1 is formed by bending a plate-like metal, but the production method is not limited to this, and can be produced by a known production method. For example, after a hollow pipe having a rectangular cross section is produced by extrusion molding, it can also be produced by cutting a necessary portion. Further, the cable support line fixing member 1 may have a substantially cylindrical shape.

図２（ａ）および図２（ｂ）に示すように、ケーブル支持線固定部材１は概略長方形の主壁１２と、主壁１２の２つの長辺１４ａ、１４ｂから主壁１２と概略垂直な方向に延出する側壁１６ａ、１６ｂとを有する。側壁１６ａ、１６ｂは対向して概略並行に配置されている。側壁１６ａ、１６ｂは支持線８６の外径よりも若干大きい高さを有するように形成されている。   As shown in FIGS. 2A and 2B, the cable support wire fixing member 1 includes a substantially rectangular main wall 12 and two main sides 12 a and 14 b of the main wall 12 that are substantially perpendicular to the main wall 12. Side walls 16a and 16b extending in the direction. The side walls 16a and 16b are arranged substantially parallel to face each other. The side walls 16 a and 16 b are formed to have a height slightly larger than the outer diameter of the support wire 86.

ケーブル支持線固定部材１は、それぞれの側壁１６ａ、１６ｂから連続的に形成され、ケーブル支持線固定部材１の長手方向中心線Ｃに向けて、主壁１２と概略平行に延出する副壁１８ａ、１８ｂを更に有する。副壁１８ａ、１８ｂは、ケーブル支持線固定部材１の長手方向中心線Ｃ付近まで延出している。副壁１８ａと副壁１８ｂとの間には、若干の隙間がある。この隙間はケーブル支持線固定部材の機能的に必要なものではないが、板状の金属を曲げ加工して成型する場合には隙間を設けた方がケーブル支持線固定部材の作製が容易となる。ケーブル支持線固定部材を押し出し加工された部材から作製する場合、この隙間を設ける必要はない。   The cable support line fixing member 1 is formed continuously from the respective side walls 16a and 16b, and extends toward the longitudinal center line C of the cable support line fixing member 1 so as to extend substantially parallel to the main wall 12. , 18b. The sub-walls 18 a and 18 b extend to the vicinity of the longitudinal center line C of the cable support line fixing member 1. There is a slight gap between the subwall 18a and the subwall 18b. This gap is not necessary for the function of the cable support line fixing member. However, when bending and forming a plate-like metal, it is easier to produce the cable support line fixing member by providing a gap. . When the cable support line fixing member is made from an extruded member, there is no need to provide this gap.

主壁１２、側壁１６ａ、１６ｂおよび副壁１８ａ、１８ｂは、断面形状が略矩形の内部空間（支持線受容部）１０を概略画定する。なお概略画定するとは、主壁１２、側壁１６ａ、１６ｂおよび副壁１８ａ、１８ｂ相互の間に隙間があっても良いことを意味し、完全に閉じた空間を画定する必要がないことを意味する。   The main wall 12, the side walls 16a and 16b, and the sub-walls 18a and 18b roughly define an internal space (support line receiving portion) 10 having a substantially rectangular cross-sectional shape. Note that the general definition means that there may be a gap between the main wall 12, the side walls 16a and 16b, and the sub-walls 18a and 18b, and it is not necessary to define a completely closed space. .

支持線受容部１０に、後述するように先端を鉤状に折り曲げた支持線８６を挿入することで、支持線８６がケーブル支持線固定部材１に対して固定される。したがって、支持線受容部１０の高さ寸法（つまり側壁１６ａ、１６ｂの高さ寸法）は、使用される支持線８６の外径よりも若干大きい寸法であることが好ましい。他方、支持線８６がケーブル支持線固定部材１の支持線受容部１０内で、ケーブル支持線固定部材１の延在方向に関して回転しないように、支持線受容部１０の高さは支持線８６の外径の２倍を越えない寸法であることが好ましい。   The support wire 86 is fixed to the cable support wire fixing member 1 by inserting a support wire 86 whose tip is bent into a hook shape as described later. Therefore, it is preferable that the height of the support wire receiving portion 10 (that is, the height of the side walls 16a and 16b) is slightly larger than the outer diameter of the support wire 86 to be used. On the other hand, the height of the support wire receiving portion 10 is such that the support wire 86 does not rotate in the support wire receiving portion 10 of the cable support wire fixing member 1 with respect to the extending direction of the cable support wire fixing member 1. It is preferable that the dimension does not exceed twice the outer diameter.

主壁１２の幅Ｗ（つまり対向する側壁間の距離）は、支持線８６の材質や折り曲げ寸法により適宜決定される。支持線８６は主壁１２の面内方向に折り曲げられるため、支持線８６の折り曲げに対する特性が主壁の幅寸法への制約となる。主壁１２の幅Ｗは、折り曲げ部８９２の支持線８６が強度を大幅に損なわない程度の曲げ半径となる寸法に設定される。   The width W of the main wall 12 (that is, the distance between the opposing side walls) is appropriately determined depending on the material of the support line 86 and the bending dimensions. Since the support line 86 is bent in the in-plane direction of the main wall 12, the characteristic of the support line 86 with respect to bending becomes a restriction on the width of the main wall. The width W of the main wall 12 is set to a dimension that provides a bending radius such that the support line 86 of the bent portion 892 does not significantly impair the strength.

ケーブル支持線固定部材１は、図２（ａ）に示すように、一方の長辺１４ａ側に設けられた側壁１６ａと並んで、ケーブル支持線固定部材１の端部側に、主壁１２から略垂直方向に延出している傾斜壁２０を有する。傾斜壁２０は主壁１２から側壁１６と略同一方向に延出しているが、傾斜壁２０の延在方向は側壁１６の延在方向（ケーブル支持線固定部材１の長手方向）と所定の角度を成している。傾斜壁２０の側壁１６ａ側の端部は、傾斜壁２０の他方の端部よりも、長手方向中心線Ｃ寄りに位置している。つまり、傾斜壁２０と側壁１６ｂとの間の距離が、ケーブル支持線固定部材１の長手方向端部側で広くなり、長手方向中心側で狭くなるように、傾斜壁２０は傾斜して配置されている。傾斜壁２０は支持線８６を挿入するときに支持線８６を支持線受容部１０に向けて案内するため、支持線挿入作業を容易にする。   As shown in FIG. 2A, the cable support line fixing member 1 is arranged on the end side of the cable support line fixing member 1 from the main wall 12 side by side with the side wall 16a provided on one long side 14a side. It has the inclined wall 20 extended in the substantially perpendicular direction. The inclined wall 20 extends from the main wall 12 in substantially the same direction as the side wall 16, but the extending direction of the inclined wall 20 is a predetermined angle with the extending direction of the side wall 16 (longitudinal direction of the cable support wire fixing member 1). Is made. The end of the inclined wall 20 on the side wall 16 a side is located closer to the longitudinal center line C than the other end of the inclined wall 20. That is, the inclined wall 20 is inclined and arranged so that the distance between the inclined wall 20 and the side wall 16b becomes wider on the end portion side in the longitudinal direction of the cable support line fixing member 1 and becomes narrower on the center side in the longitudinal direction. ing. Since the inclined wall 20 guides the support line 86 toward the support line receiving portion 10 when the support line 86 is inserted, the support line insertion work is facilitated.

ケーブル支持線固定部材１は、傾斜壁２０の一方の端部に、係止部２２を有する。係止部２２は、傾斜壁２０の端面部分であり、傾斜壁２０と隣接する側壁１６ａよりも、長手方向中心線Ｃ寄りに位置している。本実施形態において、係止部２２は、側壁１６ａよりも支持線８６の半径と概略等しい寸法だけ長手方向中心線Ｃ寄りの位置に配置されている。支持線９６の先端は鉤状に折り曲げられた状態でケーブル支持線固定部材１に挿入される。そして、対向する側壁１６ａ、１６ｂ間の距離は、支持線８６の端部８６４と基端部８６１との距離よりも小さく設定されるので、ケーブル支持線固定部材１の内部では、支持線８６の先端部８６３は基端部８６１に向かって弾性的に圧縮された状態に置かれる。この圧縮によって生じる支持線８６の弾性反発力によって、先端部８６３と基端部８６１は、それぞれに隣接する側壁１６ａ、１６ｂの内面に対して押し付けられる。これにより端部８６４は側壁１６ａの内面に接することになり、支持線８６の端面は係止部２２と当接できる位置に配置される。このようにして係止部２２は支持線８６の端部８６４と係止し、支持線８６をケーブル支持線固定部材１に対して固定する。
なお、端部８６４とは、支持線８６の先端部８６３における、折り曲げ部８６２とは反対側に位置する一端である。 The cable support line fixing member 1 has a locking portion 22 at one end of the inclined wall 20. The locking portion 22 is an end surface portion of the inclined wall 20 and is located closer to the longitudinal center line C than the side wall 16 a adjacent to the inclined wall 20. In the present embodiment, the locking portion 22 is disposed at a position closer to the longitudinal center line C by a dimension substantially equal to the radius of the support line 86 than the side wall 16a. The distal end of the support wire 96 is inserted into the cable support wire fixing member 1 in a state of being bent into a hook shape. Since the distance between the opposing side walls 16a and 16b is set to be smaller than the distance between the end portion 864 and the base end portion 861 of the support line 86, inside the cable support line fixing member 1, The distal end portion 863 is placed in an elastically compressed state toward the proximal end portion 861. By the elastic repulsive force of the support wire 86 generated by the compression, the distal end portion 863 and the proximal end portion 861 are pressed against the inner surfaces of the side walls 16a and 16b adjacent to each other. As a result, the end portion 864 comes into contact with the inner surface of the side wall 16 a, and the end surface of the support line 86 is disposed at a position where it can contact the locking portion 22. In this manner, the locking portion 22 is locked with the end portion 864 of the support wire 86 and fixes the support wire 86 to the cable support wire fixing member 1.
Note that the end portion 864 is one end located on the opposite side of the bent portion 862 at the tip end portion 863 of the support line 86.

係止部２２は支持線８６の先端部８６３と当接できる、任意の位置に配置することができる。上述のように支持線８６の端部８６４が側壁１６ａの内面に接する場合、係止部２２を、支持線８６の直径を越ない範囲で、側壁１６ａの内面から長手方向中心線Ｃ寄りに離れた位置に配置することができる。   The locking portion 22 can be disposed at any position where it can come into contact with the distal end portion 863 of the support line 86. As described above, when the end portion 864 of the support line 86 is in contact with the inner surface of the side wall 16a, the locking portion 22 is separated from the inner surface of the side wall 16a toward the longitudinal center line C within a range not exceeding the diameter of the support line 86. Can be placed at different positions.

本実施形態のケーブル支持線固定部材１は、１つの側壁１６ａと、傾斜壁２０との間に、解除部２４を更に有する。図３は、解除部２４付近を、ケーブル支持線固定部材１の下面からみた拡大図である。解除部２４は、支持線８６がケーブル支持線固定部材１に固定されたときに、支持線８６の先端部８６３と隣接する側壁１６ａに隣接して配置される。本実施形態の解除部２４では、解除部２４に隣接している主壁１２の一部が切除されている。また本実施形態の解除部２４は、側壁１６および副壁１８を有していない。そのため係止部２２に係止している支持線８６の端部８６４付近が解除部２４を通して外部に露出している。   The cable support line fixing member 1 according to the present embodiment further includes a release portion 24 between one side wall 16a and the inclined wall 20. FIG. 3 is an enlarged view of the vicinity of the release portion 24 as seen from the lower surface of the cable support line fixing member 1. The release portion 24 is disposed adjacent to the side wall 16a adjacent to the distal end portion 863 of the support line 86 when the support line 86 is fixed to the cable support line fixing member 1. In the release part 24 of this embodiment, a part of the main wall 12 adjacent to the release part 24 is cut off. Further, the release portion 24 of the present embodiment does not have the side wall 16 and the sub wall 18. Therefore, the vicinity of the end portion 864 of the support line 86 that is locked to the locking portion 22 is exposed to the outside through the release portion 24.

支持線８６とケーブル支持線固定部材１との係止を解除するときには、解除部２４を通して、支持線８６の端部８６４を支持線８６の基端部８６１側に押し込んで、支持線８６の端部８６４と係止部２２との係止を解除する。その状態で支持線８６をケーブル支持線固定部材１から離れる方向に抜去すると、支持線８６をケーブル支持線固定部材１から取り外すことができる。ケーブル支持線固定部材１が解除部２４を有すると、加入者の引越し等でケーブルを撤去する場合に、容易に支持線をケーブル支持線固定部材から取り外すことができる。   When releasing the locking between the support wire 86 and the cable support wire fixing member 1, the end portion 864 of the support wire 86 is pushed into the base end portion 861 side of the support wire 86 through the release portion 24, and the end of the support wire 86. The locking between the portion 864 and the locking portion 22 is released. In this state, when the support line 86 is removed in a direction away from the cable support line fixing member 1, the support line 86 can be detached from the cable support line fixing member 1. When the cable support line fixing member 1 has the release portion 24, the support line can be easily detached from the cable support line fixing member when the cable is removed by moving the subscriber or the like.

本実施形態では、解除部２４は主壁１２と、側壁１６と、副壁１８とを有さないが、本発明の解除部２４はこの形態に限定されるものではない。解除部２４は、支持線８６の先端部８６３を操作することで係止部２２との係止を解除できるものであればよい。例えば、隣接した副壁１８ａの一部が解除部２４を部分的に覆うようにしてもよいし、主壁１２の一部に切り欠きを設けなくともよい。   In this embodiment, the release part 24 does not have the main wall 12, the side wall 16, and the subwall 18, but the release part 24 of this invention is not limited to this form. The release unit 24 may be any unit that can release the locking with the locking unit 22 by operating the tip 863 of the support line 86. For example, a part of the adjacent sub wall 18a may partially cover the release portion 24, or a part of the main wall 12 may not be provided with a notch.

あるいは、解除部２４は主壁１２、副壁１８ａまたは側壁１６ａに開口部を設けることでも形成することができる。解除部２４を主壁１２、副壁１８ａまたは側壁１６ａに開口を設けて形成する場合、例えばマイナスドライバをその開口に挿入して係止部２２と先端部８６３との係止を解除することができる。また、解除部２４は端部８６４と折り曲げ部８６２との間の支持線の部分と隣接する、ケーブル支持線固定部材１の任意の位置に配置することができる。つまり、解除部２４を係止部２２と直接隣接する位置に配置してもよいし、係止部２２と離間して隣接する位置に配置してもよい。   Alternatively, the release portion 24 can be formed by providing an opening in the main wall 12, the sub wall 18a, or the side wall 16a. When the release portion 24 is formed by providing an opening in the main wall 12, the sub-wall 18 a or the side wall 16 a, for example, a minus driver may be inserted into the opening to release the lock between the lock portion 22 and the tip portion 863. it can. Further, the release portion 24 can be disposed at an arbitrary position of the cable support line fixing member 1 adjacent to the portion of the support line between the end portion 864 and the bent portion 862. That is, the release part 24 may be disposed at a position directly adjacent to the locking part 22 or may be disposed at a position adjacent to and spaced from the locking part 22.

図２（ａ）に示すように、本実施形態のケーブル支持線固定部材１は、解除部２４が設けられている長辺１４ａに対向する長辺１４ｂ側で、副壁１８ｂに隣接して支持線ガイド部２６を有する。支持線ガイド部２６は、ケーブル支持線固定部材１の長手方向端部に隣接して配置されている。支持線ガイド部２６は、ケーブル支持線固定部材１の端部付近の主壁１２から延出する側壁１６ｂと、側壁１６ｂから所定の間隔だけ離れて、側壁１６ｂと略並行に対向配置されたガイド片２８とを有する。ガイド片２８と側壁１６ｂとの間の寸法は、支持線８６の直径よりも若干大きい寸法とすることができる。   As shown in FIG. 2A, the cable support line fixing member 1 of the present embodiment is supported adjacent to the sub-wall 18b on the long side 14b side facing the long side 14a where the release portion 24 is provided. A line guide portion 26 is provided. The support line guide portion 26 is disposed adjacent to the longitudinal end portion of the cable support line fixing member 1. The support line guide part 26 is a guide that is disposed opposite to the side wall 16b and substantially parallel to the side wall 16b at a predetermined interval from the side wall 16b extending from the main wall 12 near the end of the cable support line fixing member 1. And a piece 28. The dimension between the guide piece 28 and the side wall 16 b can be a dimension slightly larger than the diameter of the support line 86.

後述するように、折り曲げ部８６２に隣接する基端部８６１が支持線ガイド部２６に受容されるように支持線８６を配置した後、支持線８６をケーブル支持線固定部材１に挿入する。したがって、支持線ガイド部２６は副壁１８によって覆われていない状態とすることが好ましい。もちろん、支持線ガイド部２６に支持線８６を配置可能なように、ガイド片２８の先端から充分に隙間を空けて副壁１８を配置することも可能である。   As will be described later, after the support wire 86 is disposed so that the base end portion 861 adjacent to the bent portion 862 is received by the support wire guide portion 26, the support wire 86 is inserted into the cable support wire fixing member 1. Therefore, it is preferable that the support line guide portion 26 is not covered with the sub-wall 18. Of course, it is also possible to arrange the sub-wall 18 with a sufficient gap from the tip of the guide piece 28 so that the support line 86 can be arranged in the support line guide portion 26.

支持線ガイド部２６は、支持線８６がケーブル支持線固定部材１に挿入されるときに、支持線８６を案内するだけでなく、支持線８６の座屈を防止する機能を果たすことができる。本実施形態のケーブル支持線固定部材１では、支持線８６がケーブル支持線固定部材１に対して固定された状態になる前に、支持線８６の先端部８６３が傾斜壁２０と当接する。傾斜壁２０において、先端部８６３は基端部８６１側に変位させられるので、その変位によって生じる支持線８６の弾性反発力によって、支持線８６はケーブル支持線固定部材１から離れる方向に力を受ける。そのため、支持線８６をケーブル支持線固定部材１に挿入するには、弾性反発力により生じる反力、およびそれにより生じる支持線８６とケーブル支持線固定部材１間の摩擦力よりも大きい力で支持線８６を押す必要がある。このとき、ガイド片２８がないと、作業者が支持線８６を押す力の大きさによっては、作業者が保持している支持線８６の場所と折り曲げ部８６２との間の支持線８６が先端部８６３側に向けて屈曲する恐れがある。   The support line guide portion 26 can not only guide the support line 86 when the support line 86 is inserted into the cable support line fixing member 1, but can also function to prevent buckling of the support line 86. In the cable support line fixing member 1 of the present embodiment, the tip end portion 863 of the support line 86 contacts the inclined wall 20 before the support line 86 is fixed to the cable support line fixing member 1. In the inclined wall 20, the distal end portion 863 is displaced toward the proximal end portion 861, so that the support wire 86 receives a force in a direction away from the cable support wire fixing member 1 due to the elastic repulsive force of the support wire 86 generated by the displacement. . Therefore, in order to insert the support wire 86 into the cable support wire fixing member 1, the support wire 86 is supported with a force larger than the reaction force generated by the elastic repulsion force and the friction force generated by the support wire 86 and the cable support wire fixing member 1. It is necessary to press line 86. At this time, if the guide piece 28 is not provided, depending on the magnitude of the force with which the operator pushes the support line 86, the support line 86 between the location of the support line 86 held by the operator and the bent portion 862 is the tip. There is a risk of bending toward the portion 863 side.

支持線ガイド部２６のガイド片２８は、支持線８６の基端部８６１と先端部８６３との間に位置するので、基端部８６１が先端部８６３側に向かって撓んだときにガイド片２８が支持線８６の基端部８６１に当接し、支持線８６の屈曲を防ぐことができる。このため、支持線ガイド部２６を設けることで、支持線８６の挿入作業をより容易なものとすることができる。   Since the guide piece 28 of the support line guide portion 26 is located between the base end portion 861 and the tip end portion 863 of the support line 86, the guide piece is bent when the base end portion 861 is bent toward the tip end portion 863 side. 28 abuts on the base end portion 861 of the support line 86, and the support line 86 can be prevented from bending. For this reason, by providing the support wire guide portion 26, the insertion operation of the support wire 86 can be made easier.

支持線ガイド部２６は更に、支持線８６の折り曲げ部８６２に対して、ケーブル支持線固定部材１の長手方向から支持線８６の先端部８６３側に傾いた方向に引っ張り力が作用することを防ぐことができる。例えば施工時や強風下等に、支持線８６がケーブル支持線固定部材１の長手方向から傾いた方向に引っ張られる場合が考えられる。そのような場合、ガイド片２８がないと、支持線８６の剛性や先端部８６３の長さ寸法によっては、支持線８６の先端部８６３がケーブル支持線固定部材１の中で主壁１２に平行な面内で回動する恐れがある。あるいは、折り曲げ部８６２の曲率半径が小さくなり、折り曲げ部の支持線が弾性領域を超えて曲げられることとなり、先端部８６３が基端部８６１から離れる方向に作用している支持線８６の弾性反発力が減少することも考えられる。上記のような状況が生じた場合、ケーブル支持線固定部材１が支持線８６を固定する力が、所期の力を下回る恐れがある。しかし、支持線ガイド部２６は、ケーブル支持線固定部材１の長手方向から支持線８６の先端部８６３側に傾いた方向に支持線が引っ張られることを防ぐので、上述のような状況が生じにくくなる。   Further, the support line guide part 26 prevents a tensile force from acting on the bent part 862 of the support line 86 in a direction inclined from the longitudinal direction of the cable support line fixing member 1 toward the tip end part 863 side of the support line 86. be able to. For example, it is conceivable that the support wire 86 is pulled in a direction inclined from the longitudinal direction of the cable support wire fixing member 1 during construction or under strong wind. In such a case, if the guide piece 28 is not provided, the tip portion 863 of the support wire 86 is parallel to the main wall 12 in the cable support wire fixing member 1 depending on the rigidity of the support wire 86 and the length dimension of the tip portion 863. There is a risk of turning in a plane. Alternatively, the radius of curvature of the bent portion 862 is reduced, the support line of the bent portion is bent beyond the elastic region, and the elastic repulsion of the support line 86 acting in the direction in which the distal end portion 863 is separated from the base end portion 861. The power may be reduced. When the above situation arises, the force with which the cable support wire fixing member 1 fixes the support wire 86 may be less than the expected force. However, since the support line guide part 26 prevents the support line from being pulled in the direction inclined from the longitudinal direction of the cable support line fixing member 1 to the tip end part 863 side of the support line 86, the above-described situation hardly occurs. Become.

次に図４〜図６を参照し、本実施形態のケーブル支持線固定部材１に支持線８６を固定する手順を説明する。   Next, with reference to FIGS. 4-6, the procedure which fixes the support wire 86 to the cable support wire fixing member 1 of this embodiment is demonstrated.

必要に応じて、支持線８６をケーブル部８２から必要長だけ切り離す。そして、支持線８６の端部８６４から所定長離れた位置で、支持線８６を鉤状に折り曲げる。このとき、支持線の端部８６４と基端部８６１との距離Ｌが、ケーブル支持線固定部材１の対向する側壁１６ａ、１６ｂ間の距離Ｗよりも大きくなるようにする。（図４）   If necessary, the support wire 86 is separated from the cable portion 82 by a necessary length. Then, the support line 86 is bent into a bowl shape at a position away from the end 864 of the support line 86 by a predetermined length. At this time, the distance L between the end portion 864 of the support line and the base end portion 861 is set to be larger than the distance W between the opposing side walls 16a, 16b of the cable support line fixing member 1. (Fig. 4)

次に、支持線８６の折り曲げ部８６２をケーブル支持線固定部材１に配置する。このとき、基端部８６１の折り曲げ部８６２に隣接する部分は、支持線ガイド部２６に受容される（図５）。   Next, the bent portion 862 of the support wire 86 is disposed on the cable support wire fixing member 1. At this time, a portion of the base end portion 861 adjacent to the bent portion 862 is received by the support line guide portion 26 (FIG. 5).

支持線１をケーブル支持線固定部材１に向けて押し込む。支持線８６の先端部８６３は傾斜壁２０に当接し、支持線８６の基端部８６１側に変位する（図６）。さらに支持線８６をケーブル支持線固定部材１に押し込んで、先端部８６３が傾斜壁２０を超えてケーブル支持線固定部材１の中心側に位置するようになると、先端部８６３は弾性的に広がる。支持線８６の先端部８６３と基端部８６１は、それぞれに隣接する側壁１６ｂ、１６ａの内面に対して、支持線８６の弾性反発力よって当接する。その状態で支持線８６の端部８６４は係止部２２と対向する場所に位置し、支持線８６の端部８６４が係止部２２と係止する（図３参照）。   The support wire 1 is pushed toward the cable support wire fixing member 1. The distal end portion 863 of the support line 86 abuts on the inclined wall 20 and is displaced toward the base end portion 861 side of the support line 86 (FIG. 6). Further, when the support wire 86 is pushed into the cable support wire fixing member 1 and the tip end portion 863 is positioned on the center side of the cable support wire fixing member 1 beyond the inclined wall 20, the tip end portion 863 expands elastically. The distal end portion 863 and the proximal end portion 861 of the support wire 86 abut against the inner surfaces of the side walls 16b and 16a adjacent to each other by the elastic repulsion force of the support wire 86, respectively. In this state, the end portion 864 of the support line 86 is positioned at a position facing the locking portion 22, and the end portion 864 of the support line 86 is locked with the locking portion 22 (see FIG. 3).

これら一連の工程をケーブル支持線固定部材１の他端においても行うことで、図１に示すように２つの支持線８６ａ、８６ｂを直線的に接続することができる。   By performing these series of steps also at the other end of the cable support wire fixing member 1, the two support wires 86a and 86b can be linearly connected as shown in FIG.

以上、本発明のケーブル支持線固定部材を第１の実施形態に基づいて説明したが、本発明は上記の実施形態に限られるものではない。以下、本発明の他の実施形態や変形例を説明する。なお、上述の実施形態と対応する要素には、共通の参照符号をつける。   The cable support wire fixing member of the present invention has been described based on the first embodiment, but the present invention is not limited to the above embodiment. Hereinafter, other embodiments and modifications of the present invention will be described. Note that elements corresponding to those in the above-described embodiment are denoted by common reference numerals.

図７には本発明によるケーブル支持線固定部材の第２の実施形態を示す。本実施形態によるケーブル支持線固定部材１０１は、その長手方向の略中心に阻止壁３０を有し、阻止壁３０の両側に補強部材３２を有することにおいて、第１の実施形態と異なる。   FIG. 7 shows a second embodiment of a cable support line fixing member according to the present invention. The cable support line fixing member 101 according to the present embodiment is different from the first embodiment in that the cable support line fixing member 101 has a blocking wall 30 at the approximate center in the longitudinal direction and has reinforcing members 32 on both sides of the blocking wall 30.

阻止壁３０は、支持線受容部１０に突出するように切り起こされた主壁１２の一部分である。阻止壁３０はケーブル支持線固定部材１０１の長手方向に概略中心に位置している。阻止壁３０は支持線受容部１０に挿入された支持線８６の折り曲げ部８６２と当接できる高さに切り起こされており、ケーブル支持線固定部材１０１の一方の端部から挿入された支持線８６が、誤ってケーブル支持線固定部材１０１の他端側に侵入することや、さらには他端側からケーブル支持線固定部材１０１の外部に突き抜けることを防止できる。したがって、阻止壁３０は支持線８６の折り曲げ部８６２と当接できるように構成されていれば良く、副壁１８や側壁１６の一部を折り曲げて構成することも可能であるし、別部材をケーブル支持線固定部材１０１に組付けて構成することも可能である。   The blocking wall 30 is a part of the main wall 12 cut and raised so as to protrude into the support wire receiving portion 10. The blocking wall 30 is positioned approximately at the center in the longitudinal direction of the cable support line fixing member 101. The blocking wall 30 is cut and raised to a height at which it can come into contact with the bent portion 862 of the support wire 86 inserted into the support wire receiving portion 10, and the support wire inserted from one end of the cable support wire fixing member 101. It is possible to prevent 86 from entering the other end side of the cable support line fixing member 101 by mistake, and further penetrating from the other end side to the outside of the cable support line fixing member 101. Therefore, the blocking wall 30 only needs to be configured to be able to contact the bent portion 862 of the support line 86, and the auxiliary wall 18 and the side wall 16 may be partially bent. The cable support line fixing member 101 may be assembled and configured.

補強部材３２は、支持線８６がケーブル支持線固定部材１０１に固定された後に、支持線８６の折り曲げ部８６２の内側に配置される。支持線８６に過大な張力が印加されたときに、補強部材３２は支持線８６と接触し、折り曲げ部８６２の曲率半径が小さくなることを防ぐので、補強部材３２がない場合に比べてケーブル支持線固定部材１０１による支持線８６の固定強度を高めることができる。図示の実施形態では、ケーブル支持線固定部材１０１の主壁１２に雌螺子（図示せず）を設け、支持線８６をケーブル支持線固定部材１０１に固定した後に、螺子（補強部材）３２をケーブル支持線固定部材に螺合させる。補強部材３２は支持線８６の固定強度を高める効果を発揮できるので、必要とされる支持線固定強度によっては、補強部材３２のみで支持線８６をケーブル支持線固定部材１０１に固定することも可能である。つまり、補強部材３２が係止部として機能することが可能である。   The reinforcing member 32 is disposed inside the bent portion 862 of the support line 86 after the support line 86 is fixed to the cable support line fixing member 101. When excessive tension is applied to the support wire 86, the reinforcing member 32 comes into contact with the support wire 86 and prevents the bending radius of the bent portion 862 from becoming smaller. The fixing strength of the support wire 86 by the wire fixing member 101 can be increased. In the illustrated embodiment, a female screw (not shown) is provided on the main wall 12 of the cable support line fixing member 101, and after fixing the support line 86 to the cable support line fixing member 101, the screw (reinforcing member) 32 is connected to the cable. Screw onto the support wire fixing member. Since the reinforcing member 32 can exert an effect of increasing the fixing strength of the support wire 86, the supporting wire 86 can be fixed to the cable support wire fixing member 101 only by the reinforcing member 32 depending on the required supporting wire fixing strength. It is. That is, the reinforcing member 32 can function as a locking portion.

また、図７に示すように、必要に応じて補強部材３２と副壁１８ａ、１８ｂとの干渉を防ぐ目的で、副壁１８ａ、１８ｂに凹部３４を設けても良い。補強部材３２はケーブル支持線固定部材１０１と一体に設けてもよいし、ケーブル支持線固定部材１０１とは別部材として設けてもよい。補強部材３２をケーブル支持線固定部材１０１とは別部材として設けるときには、図示の螺子以外に、円柱状や角柱状などの任意の形状の部材を補強部材として使用することができる。補強部材３２をケーブル支持線固定部材１０１と一体に設ける場合には、主壁１２または副壁１８の一部を支持線受容部１０側に折り曲げて、補強部材３２とすることもできる。   Moreover, as shown in FIG. 7, you may provide the recessed part 34 in subwall 18a, 18b in order to prevent interference with the reinforcement member 32 and subwall 18a, 18b as needed. The reinforcing member 32 may be provided integrally with the cable support line fixing member 101 or may be provided as a separate member from the cable support line fixing member 101. When the reinforcing member 32 is provided as a separate member from the cable support line fixing member 101, a member having an arbitrary shape such as a columnar shape or a prismatic shape can be used as the reinforcing member in addition to the illustrated screw. When the reinforcing member 32 is provided integrally with the cable support line fixing member 101, a part of the main wall 12 or the sub wall 18 can be bent toward the support line receiving portion 10 to form the reinforcing member 32.

図８には本発明によるケーブル支持線固定部材の第３の実施形態を示す。本実施形態によるケーブル支持線固定部材２０１は、その長手方向一端側に円形の開口部３６を有することにおいて、第１の実施形態と異なる。   FIG. 8 shows a third embodiment of a cable support line fixing member according to the present invention. The cable support line fixing member 201 according to the present embodiment is different from the first embodiment in having a circular opening 36 on one end side in the longitudinal direction.

第３の実施形態によるケーブル支持線固定部材２０１は、例えば家屋の壁面に支持線８６を固定する場合や、電柱に支持線８６を固定する場合等に使用できる。開口部３６に既設のフック等を掛けることで、ケーブル支持線固定部材２０１を家屋等に固定することができる。つまり、支持線８６同士を直線的に接続しない場合においても、本発明のケーブル支持線固定部材を使用することができる。   The cable support wire fixing member 201 according to the third embodiment can be used, for example, when the support wire 86 is fixed to the wall surface of a house or when the support wire 86 is fixed to a utility pole. By hooking an existing hook or the like to the opening 36, the cable support line fixing member 201 can be fixed to a house or the like. That is, even when the support wires 86 are not connected linearly, the cable support wire fixing member of the present invention can be used.

図９に本発明によるケーブル支持線固定部材の第４の実施形態を示す。本実施形態においては、副壁３１８がケーブル支持線固定部材３０１の一方の長辺側に設けられた側壁１６ｂのみから延出している点において、第１の実施形態と異なる。副壁３１８と他方の側壁１６ａとの間の設けられている隙間は支持線８６の外径よりも小さく設定されているので、他方の側壁１６ａから延出する副壁を有さなくとも、支持線８６を支持線受容部１０に受容することができる。また、支持線８６の基端部側８６１と隣接する側壁１６ｂから副壁３１８をケーブル支持線固定部材３０１の長手方向に延出させ、副壁３１８が支持線８６の折り曲げ部８６２をある程度覆うようにすると、支持線８６が基端部８６１を中心として軸方向に関して回転できなくなる。そのため副壁３１８と他方の側壁１６ａとの間の隙間が支持線８６の外径よりも大きい寸法を有していても、支持線８６がその隙間を通って支持線受容部１０外に脱落することを防げる。   FIG. 9 shows a fourth embodiment of a cable support line fixing member according to the present invention. This embodiment is different from the first embodiment in that the sub-wall 318 extends only from the side wall 16b provided on one long side of the cable support wire fixing member 301. Since the gap provided between the sub-wall 318 and the other side wall 16a is set to be smaller than the outer diameter of the support wire 86, the support can be provided without having a sub-wall extending from the other side wall 16a. The wire 86 can be received in the support wire receiving portion 10. Further, the auxiliary wall 318 is extended in the longitudinal direction of the cable supporting wire fixing member 301 from the side wall 16b adjacent to the base end side 861 of the supporting wire 86, and the auxiliary wall 318 covers the bent portion 862 of the supporting wire 86 to some extent. Then, the support line 86 cannot rotate about the base end portion 861 in the axial direction. Therefore, even if the gap between the sub-wall 318 and the other side wall 16a has a size larger than the outer diameter of the support line 86, the support line 86 falls out of the support line receiving portion 10 through the gap. I can prevent that.

上述の各々の実施形態において、さらに以下のよう種々の変形を行うことができる。
上述の実施形態では、傾斜壁２０の端部を係止部２２としていたが、係止部２２は他の形態で設けることができる。例えば、図１０に示すように、傾斜壁２０を長手方向に延長し、その延長した部分２１を外側に折り曲げて係止部２２とすることもできる。あるいは、副壁、副壁もしくは側壁の一部を折り曲げて係止部としてもよい。これに加え、傾斜壁２０は対向する側壁１６ｂと実質的に平行に配置しても良い。 In each of the above-described embodiments, various modifications can be further made as follows.
In the above-described embodiment, the end portion of the inclined wall 20 is the locking portion 22, but the locking portion 22 can be provided in other forms. For example, as shown in FIG. 10, the inclined wall 20 can be extended in the longitudinal direction, and the extended portion 21 can be bent outward to form the locking portion 22. Alternatively, a part of the subwall, the subwall, or the side wall may be bent to form the locking portion. In addition, the inclined wall 20 may be disposed substantially parallel to the opposing side wall 16b.

図１１に示すように、端部８６４が基端部８６１から離れる方向に向くように、先端部８６３を支持線８６の端部８６４近傍で折り曲げてもよい。支持線８６にこのような加工をした場合、係止部２２を、隣接する側壁１６ａよりもケーブル支持線固定部材１の長手方向中心線Ｃ寄りの位置に配置することもできるし、隣接する側壁１６ａと略同一の平面内に位置するように配置したり、隣接する側壁１６ａよりもケーブル支持線固定部材１の長手方向中心線Ｃから離れた位置に配置したりすることができる。これに加え、傾斜壁２０は対向する側壁１６ｂと実質的に平行に配置しても良い。   As shown in FIG. 11, the distal end 863 may be bent near the end 864 of the support line 86 so that the end 864 faces away from the base end 861. When the support line 86 is subjected to such processing, the locking portion 22 can be disposed at a position closer to the longitudinal center line C of the cable support line fixing member 1 than the adjacent side wall 16a. It can arrange | position so that it may be located in the substantially the same plane as 16a, and can arrange | position in the position away from the longitudinal direction centerline C of the cable supporting wire fixing member 1 rather than the adjacent side wall 16a. In addition, the inclined wall 20 may be disposed substantially parallel to the opposing side wall 16b.

更なる他の変形例として、端部８６４が主壁１２から離れる方向に向くように、先端部８６３を端部８６４近傍で折り曲げてもよい。この場合、副壁１８の端部や副壁１８に設けた開口部等を係止部２２とすることができる。もしくは端部８６４が主壁１２の方向を向くように、端部８６４を主壁１２方向に折り曲げてもよい。この場合、主壁１２に開口等を設けて係止部２２とすることができる。これに加え、傾斜壁２０は対向する側壁１６ｂと実質的に平行に配置しても良い。   As yet another modification, the distal end 863 may be bent near the end 864 so that the end 864 faces away from the main wall 12. In this case, an end portion of the sub wall 18, an opening provided in the sub wall 18, or the like can be used as the locking portion 22. Alternatively, the end portion 864 may be bent in the direction of the main wall 12 so that the end portion 864 faces the direction of the main wall 12. In this case, an opening or the like can be provided in the main wall 12 to form the locking portion 22. In addition, the inclined wall 20 may be disposed substantially parallel to the opposing side wall 16b.

つぎに、図１２を参照し、本発明の更なる他の実施形態を説明する。本発明の第５の実施形態によるケーブル支持線固定部材５０１は、本体５０３と、本体に移動可能に支持されているスライド部材５０４とから構成されている。スライド部材５０４は、本体の主壁１２、第1の側壁１６ａ、１６ｂおよび副壁１８ａ、１８ｂが構成する断面形状が略矩形の内部空間１０に挿入可能な大きさを有しており、スライド部材５０４上面に支持線８６を配置して、支持線８６とともに本体５０３の内部空間１０に挿入、固定される。   Next, still another embodiment of the present invention will be described with reference to FIG. A cable support line fixing member 501 according to the fifth embodiment of the present invention includes a main body 503 and a slide member 504 that is movably supported by the main body. The slide member 504 has such a size that the cross-sectional shape formed by the main wall 12, the first side walls 16a and 16b, and the sub walls 18a and 18b of the main body can be inserted into the internal space 10 having a substantially rectangular shape. A support line 86 is disposed on the upper surface of 504, and is inserted and fixed in the internal space 10 of the main body 503 together with the support line 86.

本体５０３は、概略長方形の主壁１２と、主壁１２の２つの長辺から主壁１２と概略垂直な方向に延出する第１の側壁１６ａ、１６ｂとを有する。第１の側壁１６ａ、１６ｂはスライド部材５０４が挿入可能な高さを有している。本体５０３はさらに、その主壁１２の長手方向中心線に上に、スライド部材５０４を本体５０３に固定する固定部である複数の固定孔５４０を有する。   The main body 503 includes a substantially rectangular main wall 12 and first side walls 16 a and 16 b extending from two long sides of the main wall 12 in a direction substantially perpendicular to the main wall 12. The first side walls 16a and 16b have a height at which the slide member 504 can be inserted. The main body 503 further has a plurality of fixing holes 540 which are fixing portions for fixing the slide member 504 to the main body 503 above the longitudinal center line of the main wall 12.

本体５０３は、それぞれの第１の側壁１６ａ、１６ｂから連続的に形成され、本体の長手方向中心線Ｃに向けて、主壁１２と概略平行に延出する副壁１８ａ、１８ｂを更に有する。   The main body 503 further includes sub-walls 18a and 18b that are formed continuously from the respective first side walls 16a and 16b and extend substantially parallel to the main wall 12 toward the longitudinal center line C of the main body.

スライド部材５０４は、ベース５５０と、ベース５５０に支持された操作部材５７０とを有する。ベース５５０は略直方体の部材であり、その一端側に支持線８６が係止され、他端側に操作部材５７０が支持されている。スライド部材５０４は、図１２に示すように、支持線８６が係止される一端側が、ケーブル支持線固定部材５０１の外側に向くように、本体５０３に配置される。   The slide member 504 includes a base 550 and an operation member 570 supported by the base 550. The base 550 is a substantially rectangular parallelepiped member, and a support line 86 is locked on one end side thereof, and an operation member 570 is supported on the other end side thereof. As shown in FIG. 12, the slide member 504 is disposed on the main body 503 such that one end side to which the support line 86 is locked faces the outside of the cable support line fixing member 501.

スライド部材５０４の一端側の上面５５２には、一対の第２の側壁１７ａ、１７ｂがスライド部材５０４の長手方向に延在する。一対の第２の側壁１７ａ、１７ｂの略中間には、支持線８６を係止するリブ状の部分である係止部５５６が、第２の側壁１７ａ、１７ｂと略並行に延在する。鉤状に折り曲げられた支持線８６は、その折り曲げ部８６２の内側にリブ５５６の端部がくるように、スライド部材５０４に配置される。一対の第２の側壁１７ａ、１７ｂは支持線８６の先端を弾性的に挟持し、支持線８６の先端を鉤状に保つ。係止部５５６の厚さは支持線８６の直径よりも小さくすることができるので、折り曲げ部８６２における支持線８６の曲げ半径を小さくすることができる。第２の側壁１７ａ、１７ｂと係止部５５６とは協働して、支持線８６をスライド部材５０４に対して強固に係止する。   A pair of second side walls 17 a and 17 b extend in the longitudinal direction of the slide member 504 on the upper surface 552 on one end side of the slide member 504. A locking portion 556, which is a rib-shaped portion that locks the support wire 86, extends substantially in parallel with the second side walls 17 a and 17 b, approximately in the middle between the pair of second side walls 17 a and 17 b. The support line 86 bent in a bowl shape is disposed on the slide member 504 so that the end of the rib 556 comes inside the bent portion 862. The pair of second side walls 17a and 17b elastically sandwich the tip of the support wire 86, and keep the tip of the support wire 86 in a bowl shape. Since the thickness of the locking portion 556 can be made smaller than the diameter of the support line 86, the bending radius of the support line 86 at the bent portion 862 can be reduced. The second side walls 17 a and 17 b and the locking portion 556 cooperate to firmly lock the support line 86 with respect to the slide member 504.

スライド部材５０４の他端側の上面５５４は、一端側の上面５５２よりも高い位置に設けられており、段差部分に前壁５６０が形成されている。この前壁５６０は、スライド部材５０４上に配置された支持線８６が、所定の位置よりも他端側に位置ずれすることを防止する。   The upper surface 554 on the other end side of the slide member 504 is provided at a position higher than the upper surface 552 on the one end side, and a front wall 560 is formed at the step portion. The front wall 560 prevents the support line 86 disposed on the slide member 504 from being displaced from the predetermined position to the other end side.

スライド部材５０４の他端側には、操作部材５７０が配置されている。操作部材５７０は本体５０３と係止可能に構成されており、スライド部材５０４を本体５０３に対して固定する。図１３の断面図に示すように、スライド部材５０４の他端側には、ベース５５０の上下方向に貫通する貫通孔５５８を有する。貫通孔５５８は、上側の小径部５５８ａと、小径部５５８ａの下側の拡径部５５８ｂとを有し、小径部５５８ａと拡径部５５８ｂとの段差部分に当接面５５８ｃを有している。   An operation member 570 is disposed on the other end side of the slide member 504. The operation member 570 is configured to be latchable with the main body 503, and fixes the slide member 504 to the main body 503. As shown in the cross-sectional view of FIG. 13, the slide member 504 has a through hole 558 that penetrates in the vertical direction of the base 550 on the other end side. The through hole 558 includes an upper small diameter portion 558a and a lower diameter enlarged portion 558b on the lower side, and a contact surface 558c at a step portion between the small diameter portion 558a and the enlarged diameter portion 558b. .

操作部材５７０の操作部５７４がベース５５０の上面５５４側に位置するように、操作部材５７０の軸部５７６が貫通孔５５８に挿入されている。操作部材５７０は、操作部５７４とは反対側の先端５７６ａ近傍にフランジ部５７８を有する。操作部材５７０は、フランジ部５７８の上面５７８ａと貫通孔５５８の当接面５５８ｃとの間に、操作部材５７０と略同軸状に配置された圧縮コイルバネ５８０を有する。   The shaft portion 576 of the operation member 570 is inserted into the through hole 558 so that the operation portion 574 of the operation member 570 is positioned on the upper surface 554 side of the base 550. The operation member 570 has a flange portion 578 in the vicinity of the tip 576 a on the side opposite to the operation portion 574. The operation member 570 includes a compression coil spring 580 disposed substantially coaxially with the operation member 570 between the upper surface 578 a of the flange portion 578 and the contact surface 558 c of the through hole 558.

軸部５７６の先端５７６ａがフランジ部５７８の下面５７８ｂから突出し、かつ、フランジ部５７８の下面５７８ｂとベース５５０の下面５５０ｂとが略同一面内に位置したときに、圧縮コイルバネ５８０が圧縮された状態となる軸部５７６上の位置に、フランジ部５７８は配置されている。このように構成することで、圧縮コイルバネ５８０が操作部材５７０を本体５０３の固定孔５４０に向かって付勢する。   The compression coil spring 580 is compressed when the tip 576a of the shaft portion 576 protrudes from the lower surface 578b of the flange portion 578 and the lower surface 578b of the flange portion 578 and the lower surface 550b of the base 550 are positioned in substantially the same plane. The flange portion 578 is disposed at a position on the shaft portion 576. With this configuration, the compression coil spring 580 biases the operation member 570 toward the fixing hole 540 of the main body 503.

操作部材５７０と固定孔５４０との位置が略一致する位置にスライド部材５０４を移動させると、圧縮コイルバネ５８０のバネ力により操作部材５７０の軸部５７６の先端5５７６ａが固定孔５４０に嵌入され、図１３に示すようにスライド部材５０４が本体５０３に対して係止される。また、圧縮コイルバネ５８０は、操作部材５７０と固定孔５４０とが係止した状態でもバネ力を発揮しているので、意図せずにスライド部材５０４と本体５０３との係止が解除されることを防止できる。   When the slide member 504 is moved to a position where the positions of the operation member 570 and the fixing hole 540 substantially coincide with each other, the tip 5576a of the shaft portion 576 of the operation member 570 is fitted into the fixing hole 540 by the spring force of the compression coil spring 580. As shown in FIG. 13, the slide member 504 is locked to the main body 503. Further, since the compression coil spring 580 exerts a spring force even when the operation member 570 and the fixing hole 540 are locked, the locking of the slide member 504 and the main body 503 is unintentionally released. Can be prevented.

スライド部材５０４を移動させる場合には、操作部材５７０を圧縮コイルバネ５８０のバネ力に反して引き上げることで操作部材５７０と固定孔５４０との係止を容易に解除することができる。   When the slide member 504 is moved, the operation member 570 can be easily unlocked by pulling up the operation member 570 against the spring force of the compression coil spring 580.

これまで述べたように、本実施形態のケーブル支持線固定部材５０１においては、支持線８６はスライド部材５０４の一端側の上面５５２に配置された状態で、本体５０３に対して固定される。つまり、スライド部材５０４上面５５２と、一対の第２の側壁１７ａ、１７ｂと、副壁１８ａ、１８ｂとによって、支持線受容部５１０が確定されている。   As described above, in the cable support line fixing member 501 of the present embodiment, the support line 86 is fixed to the main body 503 in a state where the support line 86 is disposed on the upper surface 552 on one end side of the slide member 504. That is, the support line receiving portion 510 is defined by the upper surface 552 of the slide member 504, the pair of second side walls 17a and 17b, and the sub walls 18a and 18b.

本実施形態のケーブル支持線固定部材５０１を使用してドロップケーブル８０の光ファイバ８４の接続と、支持線８６固定とを行う手順の一例を説明する。   An example of a procedure for connecting the optical fiber 84 of the drop cable 80 and fixing the support line 86 using the cable support line fixing member 501 of the present embodiment will be described.

１：相互に接続する一方のドロップケーブル８０から、所定の長さにわたって支持線８６とケーブル部８２とを分離する。
２：本体５０３の端部にスライド部材５０４を配置する。そして、先端を鉤状に折り曲げた支持線８６を、スライド部材５０４の上面５５２に配置する（図１２）。
３：操作部５７４を保持してスライド部材５０４をケーブル支持線固定部材５０１の中心方向に移動させ、本体５０３の最も中央側の固定孔５４０に対して操作部材５７０を係止させて、スライド部材５０４を本体５０３に固定する。
４：他方のドロップケーブル８０についても、上記の１〜３を行う。この状態で、支持線８６同士が機械的に接続されるので、光ファイバ８４の接続作業中にドロップケーブル８０に意図せぬ張力が加わっても、光ファイバ８４の接続部に張力が加わることを防止できる。また、スライド部材５０４をケーブル支持線固定部材５０１の最も中央寄りに位置させて双方のドロップケーブルを接近させているので、光ファイバ８４の取り回しが容易となり、光ファイバ８４の接続作業性が向上する。
５：双方のドロップケーブル８０の光ファイバ８４を、メカニカルスプライスやコネクタ等の任意の接続手段によって、光学的に接続する。光ファイバ８４の接続部は、適当なケースに収納しても良い。
６：光ファイバ８４の接続後に、支持線８６部分の長さに比べ、メカニカルスプライス等の接続手段で接続されたケーブル部８２の長さが長くなることがある。その場合、ケーブル部８２が過剰に撓んでしまい、ケーブル部８２の曲げによって過剰の光学損失（曲げ損失）が発生する恐れがある。そこで、必要に応じて、一方または双方のスライド部材５０４をケーブル支持線固定部材５０１の端部側に向けて移動し、所望の固定孔５０４と操作部材５７０とを係止させてケーブル部８２の過剰な撓みを除去する。 1: The support line 86 and the cable portion 82 are separated from each other from one drop cable 80 connected to each other over a predetermined length.
2: The slide member 504 is disposed at the end of the main body 503. Then, the support line 86 whose tip is bent in a hook shape is disposed on the upper surface 552 of the slide member 504 (FIG. 12).
3: Holding the operation portion 574, the slide member 504 is moved toward the center of the cable support line fixing member 501, and the operation member 570 is locked to the most central fixing hole 540 of the main body 503, so that the slide member 504 is fixed to the main body 503.
4: The above 1 to 3 are also performed for the other drop cable 80. In this state, since the support wires 86 are mechanically connected to each other, even if an unintentional tension is applied to the drop cable 80 during the connection work of the optical fiber 84, the tension is applied to the connection portion of the optical fiber 84. Can be prevented. Further, since the slide member 504 is positioned closest to the center of the cable support line fixing member 501 and both drop cables are brought close to each other, the optical fiber 84 can be easily routed and the connection workability of the optical fiber 84 is improved. .
5: Optical fibers 84 of both drop cables 80 are optically connected by an arbitrary connection means such as a mechanical splice or a connector. The connecting portion of the optical fiber 84 may be housed in an appropriate case.
6: After the optical fiber 84 is connected, the length of the cable portion 82 connected by connection means such as a mechanical splice may be longer than the length of the support wire 86 portion. In this case, the cable portion 82 is excessively bent, and there is a possibility that excessive optical loss (bending loss) may occur due to the bending of the cable portion 82. Therefore, if necessary, one or both of the slide members 504 are moved toward the end side of the cable support line fixing member 501, and the desired fixing hole 504 and the operation member 570 are locked to each other. Remove excess deflection.

このように、本実施形態のケーブル支持線固定部材５０１を使用すると、ケーブル部８２の接続作業時に余長を長くとれるので光ファイバの接続作業性が向上する。また、ケーブル部８２の接続後に、ケーブル部８２の撓みをスライド部材５０４を移動することで容易に調整できるので、ケーブル部８２に過剰な光学損失が生じないようにすることができる。   As described above, when the cable support line fixing member 501 of the present embodiment is used, the extra length can be increased during the connection work of the cable portion 82, so that the optical fiber connection workability is improved. In addition, since the bending of the cable portion 82 can be easily adjusted by moving the slide member 504 after the connection of the cable portion 82, excessive optical loss can be prevented from occurring in the cable portion 82.

上述の各実施形態では主壁１２と副壁１８とが平行に設けられている場合について説明しているが、上述の機能を阻害しない程度において、主壁１２と副壁１８とは非平行であってもよい。また、側壁１６は主壁１２から略垂直に延出する平面状の部分として説明しているが、側壁１６は平面状でなくともよく、例えば支持線８６の外径に沿うように、ケーブル支持線固定部材１の外側に膨らんだ所定の曲率半径を有する凸面状としてもよい。   In each of the above-described embodiments, the case where the main wall 12 and the sub-wall 18 are provided in parallel is described. However, the main wall 12 and the sub-wall 18 are not parallel to the extent that the above-described functions are not hindered. There may be. Although the side wall 16 is described as a planar portion extending substantially perpendicularly from the main wall 12, the side wall 16 does not have to be planar. For example, the cable support is provided along the outer diameter of the support wire 86. It is good also as the convex surface shape which has the predetermined | prescribed radius of curvature swelled outside the line fixing member 1.

本発明の第６の実施形態によるケーブル支持線固定部材６０１を、図１４から図１６を参照し説明する。図１４は第６の実施形態によるケーブル支持線固定部材６０１を示す分解斜視図であり、図１５はケーブル支持線固定部材６０１によって支持線８６を接続した状態を示す斜視図であり、図１６は図１５の部分断面図である。   A cable support line fixing member 601 according to a sixth embodiment of the present invention will be described with reference to FIGS. 14 to 16. 14 is an exploded perspective view showing a cable support line fixing member 601 according to the sixth embodiment, FIG. 15 is a perspective view showing a state where the support line 86 is connected by the cable support line fixing member 601, and FIG. It is a fragmentary sectional view of FIG.

本実施形態のケーブル支持線固定部材６０１は、図１４および図１５に示すように、本体６０３と、本体６０３に移動可能に支持されたスライド部材６０４とを有する。   As shown in FIGS. 14 and 15, the cable support line fixing member 601 of the present embodiment includes a main body 603 and a slide member 604 that is movably supported by the main body 603.

本体６０３は略長方体を有しており、他の実施形態同様に板状の金属を折り曲げる加工をすることで作製することができる。本体６０３は、概略長方形の主壁６１２と、主壁６１２の２つの長辺から主壁６１２と概略垂直な方向に延出する一対の側壁６１６ａ、６１６ｂとを有する。   The main body 603 has a substantially rectangular parallelepiped shape, and can be manufactured by bending a plate-like metal as in the other embodiments. The main body 603 includes a substantially rectangular main wall 612 and a pair of side walls 616a and 616b extending from two long sides of the main wall 612 in a direction substantially perpendicular to the main wall 612.

主壁６１２は、その長手方向中心線Ｃに沿って、本体６０３の端部近傍から中心付近に延在するガイド開口６４２を有する。ガイド開口６４２は、スライド部材６０４を移動させるときに、スライド部材６０４を案内する。   The main wall 612 has a guide opening 642 extending from the vicinity of the end of the main body 603 to the vicinity of the center along the longitudinal center line C thereof. The guide opening 642 guides the slide member 604 when the slide member 604 is moved.

主壁６１２は更に、両側辺に隣接して複数の固定孔６４０を有する。この固定孔６４０は、後述するように、スライド部材６０４の固定片６７６を係止し、スライド部材６０４を本体６０３に対して固定する固定部としての機能を有する。また、複数の固定孔６４０のうちの任意の固定孔６４０を選択して使用することで、第５の実施形態のケーブル支持線固定部材５０１同様、ケーブル部８２の接続作業時にはケーブル部８２の余長を長くすることができ、ケーブル部８２の接続後にはケーブル部８２に生じた過剰な撓みを除去することができる。   The main wall 612 further has a plurality of fixing holes 640 adjacent to both sides. As will be described later, the fixing hole 640 has a function as a fixing portion that locks the fixing piece 676 of the slide member 604 and fixes the slide member 604 to the main body 603. In addition, by selecting and using an arbitrary fixing hole 640 among the plurality of fixing holes 640, as with the cable support wire fixing member 501 of the fifth embodiment, when the cable portion 82 is connected, the remaining portion of the cable portion 82 is used. The length can be increased, and excessive bending generated in the cable portion 82 can be removed after the cable portion 82 is connected.

スライド部材６０４は、中央に第１開口部６５２を有する略矩形の第１枠部６５０と、基端部６５４で第１枠部６５０と連続して第１開口部６５２に突出している、中央に第２開口部６６０を有する略矩形の第２枠部６５８とを有する。   The slide member 604 has a substantially rectangular first frame portion 650 having a first opening 652 at the center, and a base end portion 654 that is continuous with the first frame portion 650 and protrudes into the first opening 652 at the center. A substantially rectangular second frame portion 658 having a second opening 660.

第２枠部６５８は、図１４で図示されるように、基端部６５４と対向する第２先端部６６２から、下側に向けて突出する第１ガイド片６６４を有する。第１ガイド片６６４の幅は、本体６０３のガイド開口６４２の幅よりも狭くなっている。   As illustrated in FIG. 14, the second frame portion 658 includes a first guide piece 664 that protrudes downward from a second distal end portion 662 that faces the base end portion 654. The width of the first guide piece 664 is narrower than the width of the guide opening 642 of the main body 603.

第１ガイド片６６４は、その先端に左右に広がっている第１フック６６６を有している。第１フック６６６の幅は主壁６１２のガイド開口６４２の幅よりも大きくなっており、第２枠部６５８の下面６５８ｂ（図１６参照）から本体６０３の主壁６１２の厚みと略同じか、それよりも若干大きい間隔を開けて配置されている。   The first guide piece 664 has a first hook 666 that spreads left and right at the tip. The width of the first hook 666 is larger than the width of the guide opening 642 of the main wall 612, and is substantially the same as the thickness of the main wall 612 of the main body 603 from the lower surface 658b (see FIG. 16) of the second frame portion 658. It is arranged with a gap slightly larger than that.

スライド部材６０４は、図１６に示すように、第１枠部６５０の下面６５０ｂと本体６０３の主壁６１２の上面６１２ａとが対向するように、本体６０３の主壁６１２上に配置される。スライド部材６０４が本体６０３と組み合わされたときに、第１ガイド片６６４はガイド開口６４２に挿入され、第１フック６６６は主壁６１２の下面６１２ｂ側に突出する。本体６０３の主壁６１２は、第１フック６６６と第２枠部６５８との間に包持される。これによって、スライド部材６０４はガイド開口６４２に沿って案内されるとともに、本体６０３から脱落することが防止される。   As shown in FIG. 16, the slide member 604 is disposed on the main wall 612 of the main body 603 so that the lower surface 650 b of the first frame portion 650 and the upper surface 612 a of the main wall 612 of the main body 603 face each other. When the slide member 604 is combined with the main body 603, the first guide piece 664 is inserted into the guide opening 642, and the first hook 666 protrudes toward the lower surface 612b of the main wall 612. The main wall 612 of the main body 603 is held between the first hook 666 and the second frame portion 658. Thus, the slide member 604 is guided along the guide opening 642 and is prevented from falling off from the main body 603.

第１ガイド片６６４は、図１４に示すように、その下端に略半円形の凹部６６８を有する。凹部６６８は支持線８６の半径と略同じ曲率半径を有している。後述のように、支持線８６の折り曲げ部８６２の内側が凹部６６８に配置されることで（図１６参照）、安定して支持線８６を係止することができる。つまり、第１ガイド片６６４は、支持線８６を係止する係止部としての機能を併せ持っている。   As shown in FIG. 14, the first guide piece 664 has a substantially semicircular recess 668 at its lower end. The recess 668 has a radius of curvature that is substantially the same as the radius of the support line 86. As described later, the inside of the bent portion 862 of the support wire 86 is disposed in the recess 668 (see FIG. 16), so that the support wire 86 can be locked stably. That is, the first guide piece 664 also has a function as a locking portion that locks the support wire 86.

スライド部材６０４は、基端部６５４に連続して、下側に向けて突出する第２ガイド片６７０を有する。第２ガイド片６７０は、左右に広がっている第２フック６７２を先端に有する。第２ガイド片６７０は、中央部に凹部を有さない点を除いて第１ガイド片６６４と同様である。   The slide member 604 includes a second guide piece 670 that is continuous with the base end portion 654 and protrudes downward. The second guide piece 670 has a second hook 672 that extends from side to side at the tip. The second guide piece 670 is the same as the first guide piece 664 except that it does not have a recess at the center.

第２枠部６５８は、第１ガイド片６６４と第２ガイド片６７０とによって、長手方向の２箇所で本体６０３に対して支持されている。このため、第２枠部６５８に上方向に、つまり本体６０３から離れる方向に、力が作用しても、第２枠部６５８の浮き上がりが防止される。   The second frame portion 658 is supported by the first guide piece 664 and the second guide piece 670 with respect to the main body 603 at two locations in the longitudinal direction. For this reason, even if a force acts on the second frame portion 658 upward, that is, in a direction away from the main body 603, the second frame portion 658 is prevented from being lifted.

基端部６５４と対向する第１枠部６５０の第１先端部６５６から、固定孔６４０に係止されてスライド部材６０４を本体６０３に固定する固定部である固定片６７６が、第１枠部６５０の下面６５０ｂ側に向かって突出している。   A fixing piece 676 that is a fixing portion that is locked to the fixing hole 640 and fixes the slide member 604 to the main body 603 from the first distal end portion 656 of the first frame portion 650 that faces the base end portion 654 is a first frame portion. It protrudes toward the lower surface 650b side of 650.

一対の固定片６７６の間には、固定片６７６と固定孔６４０との係止を解除する操作部である操作片６７４が延出している。操作片６７４は、第１先端部６５６から下方に延出し、さらに第１枠部６５０と略平行な方向に略直角に曲がり、本体６０３の中心方向に向かって延出している。   Between the pair of fixed pieces 676, an operation piece 674 that is an operation portion for releasing the locking between the fixed piece 676 and the fixed hole 640 extends. The operation piece 674 extends downward from the first tip portion 656, further bends at a substantially right angle in a direction substantially parallel to the first frame portion 650, and extends toward the center direction of the main body 603.

図１６に示されるように、スライド部材６０４が本体６０３に配置され固定されている状態では、スライド部材６０４の一対の固定片６７６は本体６０３の主壁６１２の固定孔６４０に挿入されて係止され、操作部６７４は本体６０３のガイド開口６４２から主壁６１２の下面６１２ｂ側に突出している。   As shown in FIG. 16, in a state where the slide member 604 is disposed and fixed to the main body 603, the pair of fixing pieces 676 of the slide member 604 are inserted into the fixing holes 640 of the main wall 612 of the main body 603 and locked. The operation unit 674 protrudes from the guide opening 642 of the main body 603 toward the lower surface 612b of the main wall 612.

固定片６７６と固定孔６４０とが係止した状態で操作片６７４を上方に向かって変位させると、第１枠部６５０は基端部６５４を基点として撓み、第１先端部６５６が本体６０３の主壁６１２上面６１２ａから離れることができる。この第１先端部６５６の変位によって、固定片６７６も本体６０３の主壁６１２から離れる方向に変位して固定片６７６が固定孔６４０から離脱し、固定片６７６と固定孔６４０との係止が解除される。   When the operation piece 674 is displaced upward in a state where the fixing piece 676 and the fixing hole 640 are locked, the first frame portion 650 is bent with the base end portion 654 as a base point, and the first tip end portion 656 is bent on the main body 603. The main wall 612 can be separated from the upper surface 612a. Due to the displacement of the first tip 656, the fixed piece 676 is also displaced in the direction away from the main wall 612 of the main body 603, the fixed piece 676 is detached from the fixed hole 640, and the fixed piece 676 and the fixed hole 640 are locked. Canceled.

再び図１４を参照すると、基端部６５４からは、更に、ケーブルガイド部６７８が延出している。ケーブルガイド部６７８は、基端部６５４の幅よりも狭い幅を有し、ケーブル支持線固定部材６０１の長手方向に延在する連結部６８０と、連結部６８０から略直角に折れ曲がり、上方に延出するガイド板部６８２とを有する。ガイド板部６８２は連結部６８０よりも広い幅を有し、下辺６８２ｂから上辺６８２ａに向かって延在する第１ガイド溝６８４と、第１ガイド溝６８４よりも長い第２ガイド溝６８６とを有する。ケーブルガイド部６７８は、図１５に示すように、支持線８６の先端部８６３を保持するとともに、ドロップケーブル８０がケーブル支持線固定部材６０１から略直線状に延出するように、ドロップケーブル８０の延出方向をコントロールする。   Referring again to FIG. 14, a cable guide portion 678 further extends from the base end portion 654. The cable guide portion 678 has a width that is narrower than the width of the base end portion 654, a connection portion 680 that extends in the longitudinal direction of the cable support line fixing member 601, bends substantially at a right angle from the connection portion 680, and extends upward. And a guide plate portion 682 to be taken out. The guide plate portion 682 has a width wider than the connecting portion 680, and includes a first guide groove 684 extending from the lower side 682b toward the upper side 682a, and a second guide groove 686 longer than the first guide groove 684. . As shown in FIG. 15, the cable guide portion 678 holds the tip end portion 863 of the support wire 86, and the drop cable 80 extends substantially linearly from the cable support wire fixing member 601. Control the extension direction.

次に、図１６を参照し、本実施形態のケーブル支持線固定部材６０１における支持線８６の固定状態を説明する。ドロップケーブル８０は、支持線８６とケーブル部８２とが一括して、ガイド板部６８２の第２ガイド溝６８６に受容されている。支持線８６の基端部８６１側がスライド部材６０４の上面に沿って配置される。支持線８６は第１ガイド片６６４先端の凹部６６８を通って、第２枠部６５８の上面６５８ａ側から下面６５８ｂ側に折り返される。支持線８６の折り曲げ部８６２は、折り曲げ部８６２の内側に第１ガイド片６６４が位置するように、スライド部材６０４に配置される。支持線８６の先端部８６３は第２開口部６６０を下から上に通過して、スライド部材６０４の基端部６５４の上面側６５８ａを通り、ガイド板部６８２に向かって延在している。支持線８６は、その端部８６４近傍で第１ガイド溝６８４に受容されている。   Next, with reference to FIG. 16, the fixed state of the support line 86 in the cable support line fixing member 601 of this embodiment is demonstrated. In the drop cable 80, the support wire 86 and the cable portion 82 are collectively received in the second guide groove 686 of the guide plate portion 682. The base end portion 861 side of the support line 86 is disposed along the upper surface of the slide member 604. The support line 86 passes through the recess 668 at the tip of the first guide piece 664 and is folded back from the upper surface 658a side to the lower surface 658b side of the second frame portion 658. The bent portion 862 of the support line 86 is disposed on the slide member 604 so that the first guide piece 664 is positioned inside the bent portion 862. The distal end portion 863 of the support line 86 passes through the second opening 660 from the bottom to the top, passes through the upper surface side 658 a of the base end portion 654 of the slide member 604, and extends toward the guide plate portion 682. The support line 86 is received in the first guide groove 684 near the end 864 thereof.

支持線８６の先端部８６３は、側面から見たときに略への字状に折り曲げられた状態となる。このように先端部８６３をへの字状にすることで、支持線８６の折り曲げ部８６２が係止部である第１ガイド片６６４に対してより強く押し当てられることになり、支持線８６と係止部６６４との抵抗が増大する。つまり、基端部６５４は、支持線８６の先端部８６３を、単にＵターンさせた状態よりも支持線８６の基端部８６１側に近づけさせるバイアス部として機能し、ケーブル支持線固定部材６０１による支持線８６の固定強度を効果的に増大させることができる。   The distal end portion 863 of the support line 86 is bent into a substantially U shape when viewed from the side. Thus, by making the tip end portion 863 into a U-shape, the bent portion 862 of the support line 86 is more strongly pressed against the first guide piece 664 that is the locking portion. Resistance with the locking portion 664 increases. That is, the base end portion 654 functions as a bias portion that brings the tip end portion 863 of the support wire 86 closer to the base end portion 861 side of the support wire 86 than the state where the support wire 86 is simply U-turned, and is based on the cable support wire fixing member 601. The fixing strength of the support wire 86 can be effectively increased.

本実施形態のケーブル支持線固定部材６０１においても、支持線８６をケーブル支持線固定部材６０１に容易に取り付けることができる。支持線の先端を鉤状に折り曲げ、折り曲げ部８６２を第１開口部６５２とガイド開口６４２へ上側から下側に向けて挿入する。先端部８６３がガイド開口６４２を完全に通過するまで挿入したのち、支持線８６を挿入方向とは反対側に引っ張り、先端部８６３を第２開口６６０の下側から上側に通過させる（図１７）。支持線８６の折り曲げ部８６２内側に、係止部である第１ガイド片６６４が配置される。折り曲げ部８６２内側が係止部６６４と当接するまで支持線８６を引っ張ってから、支持線８６の端部８６４近傍を第１ガイド溝６８４に受容させ、支持線８６の基端部８６１側をケーブル部８２とともに第２ガイド溝６８６に受容させる。このような手順により、支持線８６をケーブル支持線固定部材６０１に固定することができる。   Also in the cable support line fixing member 601 of this embodiment, the support line 86 can be easily attached to the cable support line fixing member 601. The tip of the support line is bent in a bowl shape, and the bent portion 862 is inserted into the first opening 652 and the guide opening 642 from the upper side to the lower side. After the distal end portion 863 is inserted until it completely passes through the guide opening 642, the support line 86 is pulled to the side opposite to the insertion direction, and the distal end portion 863 is passed from the lower side to the upper side of the second opening 660 (FIG. 17). . A first guide piece 664 that is a locking portion is disposed inside the bent portion 862 of the support line 86. After pulling the support line 86 until the inside of the bent part 862 contacts the locking part 664, the vicinity of the end part 864 of the support line 86 is received in the first guide groove 684, and the base end part 861 side of the support line 86 is connected to the cable. The second guide groove 686 is received together with the portion 82. With such a procedure, the support wire 86 can be fixed to the cable support wire fixing member 601.

第６の実施形態のケーブル支持線固定部材６０１においても、第５の実施形態のケーブル支持線固定部材５０１と同様に、ケーブル部８２の光ファイバ８４接続時に必要に応じてスライド部材６０４を前に移動させて、光ファイバ８４の接続作業中に余長を長くすることができる。さらに、光ファイバ８４の接続後にスライド部材６０４を後に移動させ、接続されたケーブル部８２の過剰な撓みが解除される位置で、スライド部材６０４を本体６０３に対して固定することができる。   Similarly to the cable support line fixing member 501 of the fifth embodiment, the cable support line fixing member 601 of the sixth embodiment also moves the slide member 604 forward as necessary when the optical fiber 84 of the cable portion 82 is connected. The extra length can be increased during the connection work of the optical fiber 84 by being moved. Furthermore, the slide member 604 can be moved later after the optical fiber 84 is connected, and the slide member 604 can be fixed to the main body 603 at a position where excessive bending of the connected cable portion 82 is released.

本実施形態のケーブル支持線固定部材６０１では、その一対の側壁６１６ａ、６１６ｂの間に、光ファイバを接続したスプライスやコネクタの光ファイバ接続手段を配置することができる。そのため、光ファイバの接続手段とケーブル支持線固定部材６０１とを容易に一体的に取り扱うことができる。また、光ファイバ接続手段や、その前後の支持線を引き剥がしたケーブル部に意図しない張力や外力から保護することもできる。   In the cable support line fixing member 601 of this embodiment, an optical fiber connecting means such as a splice or a connector to which an optical fiber is connected can be disposed between the pair of side walls 616a and 616b. Therefore, the optical fiber connecting means and the cable support line fixing member 601 can be easily and integrally handled. Further, it is possible to protect the optical fiber connecting means and the cable portion from which the support wires before and after the optical fiber connecting means are peeled off from unintended tension and external force.

第６の実施形態のケーブル支持線固定部材６０１は上述の実施形態に限られるものではなく、各種の変形が行える。上記の実施形態では、第１ガイド片６６４が係止部として機能しているが、他の部位を係止部としてもよい。例えば、第１ガイド片を他の部位に配置して、第２枠部の第２先端部を係止部としてもよい。   The cable support line fixing member 601 of the sixth embodiment is not limited to the above-described embodiment, and various modifications can be made. In the above embodiment, the first guide piece 664 functions as a locking portion, but other portions may be used as the locking portion. For example, the first guide piece may be disposed in another part, and the second tip portion of the second frame portion may be used as the locking portion.

スライド部材を本体に移動可能に支持する構造も本実施形態に限られず、公知の任意の構造をとることができる。また、本体に副壁を設けて、第５の実施形態と同様にスライド部材を移動可能に支持してもよい。   The structure for supporting the slide member movably on the main body is not limited to this embodiment, and any known structure can be adopted. Further, a sub-wall may be provided on the main body, and the slide member may be movably supported as in the fifth embodiment.

ガイド板部６８２は、１つのガイド溝のみを有し、１つのガイド溝が支持線８６の先端部８６３と、支持線８６の基端部８６１とケーブル部８２とを受容するようにしてもよい。例えば、１つのガイド溝に、縦にケーブル部８２と支持線８６の基端部８６１と先端部８６３とを配置してもよい。このようにすると、ケーブル支持線固定部材６０１の幅方向（ケーブル支持線固定部材の長手方向に垂直な方向であり、かつ、主壁の面内方向と平行な方向）に関して、支持線８６の先端部８６３と基端部８６１とが同じ位置に配置される。そのため、折り曲げ部８６２前後で支持線８６にねじりが加わらないので、支持線８６の先端部８６３側と基端部８６１側の双方が、ケーブル支持線固定部材６０１から直線的に導出され、ドロップケーブル８０に不要な曲げやねじりの力が生じる恐れを、さらに低くすることができる。   The guide plate portion 682 may have only one guide groove, and one guide groove may receive the distal end portion 863 of the support wire 86, the proximal end portion 861 of the support wire 86, and the cable portion 82. . For example, the cable portion 82 and the proximal end portion 861 and the distal end portion 863 of the support wire 86 may be arranged vertically in one guide groove. In this way, with respect to the width direction of the cable support line fixing member 601 (the direction perpendicular to the longitudinal direction of the cable support line fixing member and parallel to the in-plane direction of the main wall), the tip of the support line 86 The portion 863 and the base end portion 861 are disposed at the same position. Therefore, since the support wire 86 is not twisted before and after the bent portion 862, both the distal end portion 863 side and the proximal end portion 861 side of the support wire 86 are linearly led out from the cable support wire fixing member 601, and the drop cable The possibility that an unnecessary bending or twisting force is generated in 80 can be further reduced.

本明細書では光ファイバ芯線を内蔵するドロップケーブルを例にケーブル支持線固定部材の各実施形態を説明したが、本発明はドロップケーブル以外の光ファイバケーブルへも適用できるし、電力ケーブル等の光ファイバケーブル以外のケーブルへも適用できる。また、ケーブル部と支持線とが一体的に構成されていないケーブルについても、同様に本発明を適用することができる。   In the present specification, each embodiment of the cable support line fixing member has been described by taking a drop cable having a built-in optical fiber core as an example. However, the present invention can be applied to an optical fiber cable other than a drop cable, and an optical cable such as a power cable. It can also be applied to cables other than fiber cables. Further, the present invention can be similarly applied to a cable in which the cable portion and the support wire are not integrally configured.
