Description

本発明は、高圧線に引下線用コネクタを介して引下線を電気的・機械的に接続する際に、引下線用コネクタを支持することができる間接活線工法に好適な引下線用コネクタ支持具に関する。   The present invention provides an underline connector support suitable for an indirect hot wire method capable of supporting an underline connector when the underline is electrically and mechanically connected to a high voltage line via an underline connector. Concerning ingredients.

電柱間に架設される高圧線には、高圧線を分岐させて柱上変圧器に引き込む引下線が接続される。引下線は、高圧線に固定される引下線用コネクタを介して高圧線と電気的・機械的に固定される。
引下線用コネクタについて図1を参照して説明する。
引下線用コネクタ200は、高圧線W1を挟圧する円弧状の挟圧部(挟圧面)211、221が互いの対向面に形成された第一挟圧片210及び第二挟圧片220とを備えている。また引下線用コネクタ200は、第一挟圧片210及び第二挟圧片220の夫々に貫通形成されて互いに連通する第一挿通孔212及び第二挿通孔222と、第二挟圧片220側から第二挿通孔222及び第一挿通孔212に跨がって軸部231bが挿通されると共に第二挟圧片220に対する相対回転を禁止されたボルト231と、第一挟圧片210の第一挿通孔212から突出したボルト231の軸部231bに螺着されるナット233と、を備えている。また、ボルト231は、その頭部231a近傍の軸部231bに貫通形成されて引下線W2を挿通するための引下線挿通穴232を備えている。更に、引下線用コネクタ200は、第一挟圧片210と第二挟圧片220とを一体化すると共に、2つの挟圧部211、221を互いに離間させる方向に弾性付勢する概略C字形状の線材からなるバネ部材234を備えている。
The high-voltage line laid between the power poles is connected to a pull-down line that branches the high-voltage line and draws it into the pole transformer. The underline is electrically and mechanically fixed to the high voltage line via a draw line connector fixed to the high voltage line.
The underline connector will be described with reference to FIG.
The underline connector 200 includes a first pinching piece 210 and a second pinching piece 220 in which arc-shaped pinching portions (pressing surfaces) 211 and 221 for pinching the high-voltage line W1 are formed on the opposing surfaces. I have. The underline connector 200 includes a first insertion hole 212 and a second insertion hole 222 that are formed through the first clamping piece 210 and the second clamping piece 220 to communicate with each other, and the second clamping piece 220. The shaft 231b is inserted over the second insertion hole 222 and the first insertion hole 212 from the side, and the relative rotation with respect to the second pressing piece 220 is prohibited, and the first pressing piece 210 A nut 233 that is screwed onto the shaft portion 231b of the bolt 231 protruding from the first insertion hole 212. Further, the bolt 231 is provided with a drawing line insertion hole 232 that is formed through the shaft portion 231b in the vicinity of the head portion 231a to insert the drawing line W2. Further, the underline connector 200 integrates the first pinching piece 210 and the second pinching piece 220 and elastically biases the two pinching portions 211 and 221 away from each other. A spring member 234 made of a shaped wire is provided.

引下線用コネクタを高圧線に固定する際には、引下線用コネクタを支持するコネクタ支持具が用いられる。図5は、従来のコネクタ支持具の使用状況を示す図であり、図1の矢印B方向から観察した図に対応する。
従来のコネクタ支持具240は、コネクタ200の下端部(バネ部材234側)を収容する概略円筒状の収容部241と、収容部241の側面に形成されてバネ部材234が挿入されるスリット242と、絶縁操作棒(不図示)の先端に着脱自在に装着するための菊座部243とを備えている。コネクタ支持具240は、予め絶縁操作棒の先端に固定された状態にて使用される。
従来は、引下線W2を保持したコネクタ200を高圧線W1周りに1周させて引下線W2を高圧線W1に巻き付けた後、絶縁操作棒の先端に取り付けられたコネクタ支持具240をコネクタ200に装着し、挟圧部211、221間に高圧線W1が位置するように絶縁操作棒を操作してコネクタ200を移動させていた。
しかし、コネクタ200は重心位置の関係から引下線W2周りに回転して横を向いた姿勢で安定してしまい、バネ部材234が下方に向くことは殆どない。そのため、作業員の一人が絶縁ヤットコを操作してバネ部材234が下方に位置するようにコネクタ200の向きを調整し、もう一人の作業員が絶縁操作棒の先端に固定されたコネクタ支持具240を、コネクタ200の真下からコネクタ200に装着する必要があり、コネクタ200にコネクタ支持具240を装着する作業に無駄に多くの時間を要していた。
When the underline connector is fixed to the high-voltage line, a connector support that supports the underline connector is used. FIG. 5 is a diagram illustrating a usage state of a conventional connector support, and corresponds to a diagram observed from the direction of arrow B in FIG. 1.
The conventional connector support 240 includes a substantially cylindrical accommodating portion 241 that accommodates the lower end portion (spring member 234 side) of the connector 200, and a slit 242 that is formed on the side surface of the accommodating portion 241 and into which the spring member 234 is inserted. , And a chrysanthemum part 243 for detachably attaching to the tip of an insulating operation rod (not shown). The connector support 240 is used in a state of being fixed in advance to the tip of the insulating operation rod.
Conventionally, after the connector 200 holding the underline W2 is made to make one turn around the high-voltage line W1 and the underline W2 is wound around the high-voltage line W1, the connector support 240 attached to the tip of the insulating operation rod is attached to the connector 200. The connector 200 is moved by operating the insulation operating rod so that the high-voltage line W1 is positioned between the clamping parts 211 and 221.
However, the connector 200 is stabilized in a posture in which the connector 200 rotates around the underline W2 and faces sideways because of the position of the center of gravity, and the spring member 234 rarely faces downward. For this reason, one of the workers operates the insulating jacket to adjust the orientation of the connector 200 so that the spring member 234 is positioned below, and the other worker fixes the connector support 240 fixed to the tip of the insulating operating rod. Therefore, it is necessary to attach the connector support 240 to the connector 200 from a position just below the connector 200, and much time is wasted.

コネクタを支持する支持具として特許文献1には、コネクタのボルトの頭部及びナットを嵌める受け部を一端部に有して対向配置された2枚の側板部と、側板部の他端部に配置されて2枚の側板部間の距離を一定に保持する架橋部材と、側板部の中間部に配置されて2枚の側板部の間隔を拡大又は縮小させるボルト及びナットを備えた支持具が記載されている。   As a support for supporting a connector, Patent Document 1 discloses that two side plate portions having a receiving portion for fitting a bolt head of a connector and a nut at one end portion and arranged opposite to each other, and the other end portion of the side plate portion. A support member including a bridging member that is arranged and maintains a constant distance between the two side plate portions, and a bolt and a nut that are arranged at an intermediate portion of the side plate portion and that enlarges or reduces the distance between the two side plate portions. Have been described.

しかし、特許文献1に記載の支持具をコネクタから取り外す場合は、間接ラチェットにてナットを緩める必要があり、取り外し作業が繁雑である。また、支持具を落下させないために、二人の作業員の共同作業が必要となる。
本発明は上述の事情に鑑みてなされたものであり、引下線用コネクタに着脱自在に装着され、引下線用コネクタを高圧線に対して電気的・機械的に固定する作業を行う際に引下線用コネクタを支持する引下線用コネクタ支持具であって、間接活線用の作業用具として好適であり、且つ、簡単な操作で引下線用コネクタからの取り外しを容易に行えるようにした新規な引下線用コネクタ支持具を提供することを目的とする。
However, when removing the support described in Patent Document 1 from the connector, it is necessary to loosen the nut with an indirect ratchet, and the removal work is complicated. In addition, in order not to drop the support tool, it is necessary to work together by two workers.
The present invention has been made in view of the above-described circumstances, and is detachably attached to the underline connector, and is pulled when performing the work of electrically and mechanically fixing the underline connector to the high voltage line. A novel underline connector support tool for supporting an underline connector, which is suitable as a work tool for indirect live lines, and can be easily detached from the underline connector with a simple operation. An object of the present invention is to provide an underline connector support.

[First embodiment]
The underline connector support according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view showing a usage state of the underline connector support according to the first embodiment of the present invention. FIG. 2 is a view as seen from an arrow A and a view as seen from an arrow B in FIG.
The underline connector support tool (hereinafter simply referred to as “support tool”) according to the first embodiment of the present invention is provided with two holding members that are attached to the outer surface of the holding piece of the connector and hold the holding piece. It is characterized in that it is configured to open and close one of the parts so that the support can be easily attached to and detached from the connector.

引下線用コネクタ支持具(支持具1)は、ベース10と、第一挟圧片210の外側面に添設される第一挟持部21を備えると共にベース10によって支持された第一挟持部材20と、一端部に、第二挟圧片220の外側面に添設されることにより第一挟持部21との間で第一挟圧片210及び第二挟圧片220を挟持する第二挟持部31を備え、中間部にベース10によって回動自在に支持された軸支部33を備え、他端部に軸支部33を中心として第二挟持部31を第一挟持部21に対して開閉動作させる操作部35を備えた第二挟持部材30と、ベース10に設けられて絶縁ヤットコにて把持可能な把持部50と、を備えている。
ベース10、第一挟持部材20、第二挟持部材30、及び把持部50は、容易には変形しない程度の剛性を有した金属、樹脂等から構成される。
The underline connector support tool (support tool 1) includes a base 10 and a first clamping member 20 that includes a first clamping part 21 that is attached to the outer surface of the first clamping piece 210 and is supported by the base 10. And the second sandwiching part that sandwiches the first sandwiching piece 210 and the second sandwiching piece 220 between the first sandwiching part 21 by being attached to the outer surface of the second sandwiching piece 220 at one end. The first pinching portion 21 is opened and closed with the shaft support portion 33 rotatably supported by the base 10 at the intermediate portion and the second pinching portion 31 around the shaft support portion 33 at the other end portion. A second holding member 30 provided with the operating portion 35 to be operated, and a gripping portion 50 provided on the base 10 and gripped by an insulating jacket.
The base 10, the first clamping member 20, the second clamping member 30, and the grip portion 50 are made of metal, resin, or the like having a rigidity that does not easily deform.

ベース10は、第一挟持部材20、第二挟持部材30、及び把持部50を一体化させる部材であり、ベース10には第一挟持部材20及び把持部50が固定されている。ベース10に対して第二挟持部材30のみが回動動作する構成であり、支持具1の構成が簡略化されている。
ベース10は概略平板状であり、ベース10の一面10a側には、第一挟持部材20及び第二挟持部材30の第二挟持部31が一面10aと交差する方向に突出している。ベース10の他面10b側には第二挟持部材30の操作部35及び、把持部50が突出している。本実施形態におけるベース10は、概略平板状であるが、その形状は特に限定されない。
The base 10 is a member that integrates the first clamping member 20, the second clamping member 30, and the gripping part 50, and the first clamping member 20 and the gripping part 50 are fixed to the base 10. Only the second clamping member 30 rotates with respect to the base 10, and the configuration of the support 1 is simplified.
The base 10 has a substantially flat plate shape, and the second clamping portion 31 of the first clamping member 20 and the second clamping member 30 protrudes in a direction intersecting the one surface 10a on the one surface 10a side of the base 10. On the other surface 10 b side of the base 10, the operation part 35 and the grip part 50 of the second clamping member 30 protrude. Although the base 10 in this embodiment is substantially flat plate shape, the shape is not particularly limited.

第一挟持部材20の第一挟持部21は、ナット233を外部に露出させる第一開口23を有する。コネクタ200を高圧線W1に取り付ける際には、間接ラチェット等のレンチ類を用いてナット233をボルト231に締結させる必要があるから、ナット233は、支持具1をコネクタ200に装着した状態で支持具1から露出している必要がある。従って、第一挟持部材20の第一挟持部21の厚さ(図1中左右方向の長さ)は、ナット233の軸方向長よりも短く(薄く)設定される。これにより、ナット233は第一開口23から第一挟圧片210との非対向面側へ突出する。第一挟持部21から露出したナット233に間接ラチェット等のレンチ類(不図示)を嵌合又は係合させることができ、ナット233をボルト231に締結することができる。   The first clamping part 21 of the first clamping member 20 has a first opening 23 that exposes the nut 233 to the outside. When attaching the connector 200 to the high-voltage line W1, it is necessary to fasten the nut 233 to the bolt 231 using a wrench such as an indirect ratchet. Therefore, the nut 233 is supported with the support 1 attached to the connector 200. The tool 1 must be exposed. Therefore, the thickness (length in the left-right direction in FIG. 1) of the first clamping portion 21 of the first clamping member 20 is set shorter (thinner) than the axial length of the nut 233. As a result, the nut 233 protrudes from the first opening 23 toward the non-opposing surface with the first pinching piece 210. A wrench (not shown) such as an indirect ratchet can be fitted or engaged with the nut 233 exposed from the first clamping unit 21, and the nut 233 can be fastened to the bolt 231.

図2に示す第一開口23は、第一挟持部21の長手方向の一端縁21aを切り欠いた凹状の切欠きである。第一開口23の開口幅tは、切欠きに沿ってナット233が進退移動可能な大きさに設定されている。このため、ナット233は第一挟持部21に対して、第一開口23に沿って図2中上下方向に移動可能である。図1のように第一挟持部材20がベース10に対して固定されていたとしても、第二挟持部材30を第二挟持片220から離間させて支持具1を下方に移動させれば、支持具1を引下線用コネクタ200から容易に取り外すことができる。   The first opening 23 shown in FIG. 2 is a concave notch formed by notching one end edge 21 a in the longitudinal direction of the first clamping part 21. The opening width t of the first opening 23 is set to a size that allows the nut 233 to move forward and backward along the notch. For this reason, the nut 233 is movable in the vertical direction in FIG. Even if the first clamping member 20 is fixed to the base 10 as shown in FIG. 1, if the second clamping member 30 is moved away from the second clamping piece 220 and the support 1 is moved downward, it is supported. The tool 1 can be easily detached from the underline connector 200.

第二挟持部材30の第二挟持部31は、第一挟持部21に対向して配置されており、第一挟持部21と第二挟持部31との対向面にて、コネクタ200を挟持する。
第二挟持部材30は、長手方向中間部に設けた軸支部33において、ベース10によって回動自在に軸支されており、第二挟持部31は軸支部33を中心として回動しつつ第一挟持部21に対して接離移動する。
第二挟持部材30の第二挟持部31は、ボルト231の頭部231aを外部に露出させる第二開口37を有する。第二開口37は、第二挟持部31の短手方向の一端縁31cを切り欠いた切欠きである。第二開口37は、引下線挿通穴232から引き出された引下線W2及びボルト231の頭部231aが第二挟持部31の内側の面(第一挟持部21との対向面)と干渉しないようにする。このようにすることで、第二挟持部31の内側の面(第一挟持部21との対向面)を第二挟圧片220の外側面から浮かないようにすることができ、コネクタ200挟持した支持具1のコネクタ200からの脱落やガタツキを防止する。なお、第二挟持部31は回動により、第一挟持部21に対して接近又は離間移動するので、第二開口37の一端縁31c側の開口幅は第一開口23とは異なり、必ずしもボルト231の頭部231aが通過可能である必要はない。
また、第二開口37を短手方向の一端縁31cから形成したことにより、第二挟持部31の長手方向一端部(上端部)は、ボルト231の頭部231aに係止可能な係止部39が形成されている。係止部39をボルト231の頭部231aに係止することにより、支持具1がコネクタ200に吊り下げられる格好となるので、支持具1がコネクタ200から脱落しにくくなる。
第二挟持部材30の長手方向他端部には、第二挟持部材30を回転操作するための操作部35が形成されている。第二挟持部31は、操作部35を軸支部33周りに回動させることにより、その回動操作に伴って、第一挟持部21に対して矢印C方向に接離移動する。
絶縁ヤットコ250と接触する操作部35の表面には、滑止部材36が配置されている。滑止部材36は、絶縁ヤットコ250との間で高い摩擦力を発生させる材料(例えばゴム等)を塗布するか、又は当該材料からなるシート状部材を貼付すること等により形成される。或いは、操作部35の表面に複数の溝(又は凹凸)を形成して、これを滑止部材としてもよい。絶縁ヤットコ250にて操作部35を操作したときに、絶縁ヤットコの滑動を防止して操作性を向上させる。
The second clamping part 31 of the second clamping member 30 is arranged to face the first clamping part 21, and clamps the connector 200 on the facing surface between the first clamping part 21 and the second clamping part 31. .
The second clamping member 30 is pivotally supported by the base 10 at a pivotal support portion 33 provided in the middle portion in the longitudinal direction, and the second clamping portion 31 is pivoted about the pivotal support portion 33 to the first. It moves toward and away from the clamping part 21.
The 2nd clamping part 31 of the 2nd clamping member 30 has the 2nd opening 37 which exposes the head 231a of the volt | bolt 231 outside. The second opening 37 is a notch formed by notching one end edge 31 c of the second clamping portion 31 in the short direction. The second opening 37 is such that the underline W2 drawn out from the underline insertion hole 232 and the head 231a of the bolt 231 do not interfere with the inner surface of the second clamping part 31 (the surface facing the first clamping part 21). To. By doing so, the inner surface of the second clamping part 31 (the surface facing the first clamping part 21) can be prevented from floating from the outer surface of the second clamping piece 220, and the connector 200 is clamped. This prevents the support tool 1 from falling off or loosening from the connector 200. In addition, since the 2nd clamping part 31 moves to approach or separate with respect to the 1st clamping part 21 by rotation, the opening width by the side of the one end edge 31c of the 2nd opening 37 differs from the 1st opening 23, and is not necessarily a volt | bolt. It is not necessary that the head 231a of 231 can pass through.
Further, since the second opening 37 is formed from the one end edge 31c in the short direction, the one end portion (upper end portion) in the longitudinal direction of the second holding portion 31 can be locked to the head portion 231a of the bolt 231. 39 is formed. By locking the locking portion 39 to the head 231 a of the bolt 231, the support tool 1 can be suspended from the connector 200, so that the support tool 1 is less likely to drop off from the connector 200.
An operation portion 35 for rotating the second clamping member 30 is formed at the other longitudinal end of the second clamping member 30. The second clamping unit 31 is moved toward and away from the first clamping unit 21 in the direction of the arrow C by rotating the operation unit 35 around the shaft support unit 33 with the rotation operation.
A non-slip member 36 is disposed on the surface of the operation unit 35 that comes into contact with the insulating Yatco 250. The non-slip member 36 is formed by applying a material (for example, rubber or the like) that generates a high frictional force with the insulating jacket 250 or by sticking a sheet-like member made of the material. Alternatively, a plurality of grooves (or irregularities) may be formed on the surface of the operation unit 35 and used as a non-slip member. When the operation unit 35 is operated with the insulating Yachto 250, the insulating Yatco is prevented from sliding and the operability is improved.

支持具1は、第二挟持部材30を閉止方向(第一挟持部材20に対して接近する方向)に常時弾性付勢する弾性付勢部材(不図示)を備えている。弾性付勢部材は、例えば軸支部33に内蔵したトーションバネとすることができる。
把持部50は、ベース10に設けられている。把持部50は、ベース10の他面10b(第一挟持部材20が形成された面とは反対の面)から、この面と交差する方向に突出形成されている。
絶縁ヤットコ250と接触する把持部50の表面には滑止部材51が配置されている。滑止部材51は、絶縁ヤットコ250との間で高い摩擦力を発生させる材料(例えばゴム等)を塗布するか、又は当該材料からなるシート状部材を貼付すること等により形成される。或いは、操作部35の表面に複数の溝を形成して、これを滑止部材としてもよい。絶縁ヤットコ250にて把持部50を把持等したときに、絶縁ヤットコ250の滑動を防止して操作性を向上させる。
把持部50のベース10寄りの位置には、外方に突出したつば状のヤットコストッパ53が設けられている。ヤットコストッパ53は、容易には変形しない程度の剛性を有した金属、樹脂等から構成される。ヤットコストッパ53は、絶縁ヤットコ250にて把持部50を把持したとき、把持部50に対する絶縁ヤットコ250の、図中上下方向における位置を安定させる。ヤットコストッパ53は、把持部50と一体形成されてもよいし、別体として構成された部品を後に一体化させたものでもよい。
The support 1 includes an elastic biasing member (not shown) that constantly elastically biases the second clamping member 30 in the closing direction (direction approaching the first clamping member 20). The elastic biasing member can be, for example, a torsion spring built in the shaft support portion 33.
The grip 50 is provided on the base 10. The grip portion 50 is formed to project from the other surface 10b of the base 10 (the surface opposite to the surface on which the first clamping member 20 is formed) in a direction intersecting with this surface.
A non-slip member 51 is disposed on the surface of the grip portion 50 that contacts the insulating Yatco 250. The non-slip member 51 is formed by applying a material (for example, rubber or the like) that generates a high frictional force with the insulating jacket 250 or by sticking a sheet-like member made of the material. Alternatively, a plurality of grooves may be formed on the surface of the operation unit 35, and these may be used as non-slip members. When the gripping portion 50 is gripped by the insulating jacket 250, the sliding of the insulating jacket 250 is prevented and the operability is improved.
A flange-shaped Yatco stopper 53 protruding outward is provided at a position near the base 10 of the grip 50. The Yatco stopper 53 is made of a metal, resin, or the like having a rigidity that does not easily deform. The Yatco stopper 53 stabilizes the position of the insulating YT 250 in the vertical direction in the figure with respect to the holding unit 50 when the holding unit 50 is held by the insulating YT 250. The Yatco stopper 53 may be formed integrally with the gripping part 50, or may be formed by later integrating parts configured separately.

第一挟持部21と第二挟持部31の面内の適所には、バネ部材234を外部に露出させて、各挟持部とバネ部材234との干渉を防止するスリット状のバネ部材露出穴25、41が貫通形成されている。なお、バネ部材234は、必ずしも外部に露出させる必要はない。例えば、各挟持部のコネクタ200との対向面にバネ部材234を受け入れる凹所を形成して、各挟持部とバネ部材234との干渉を防止する構成としてもよい。   A slit-like spring member exposure hole 25 that exposes the spring member 234 to the outside and prevents interference between each of the sandwiching portions and the spring member 234 at appropriate positions in the plane of the first sandwiching portion 21 and the second sandwiching portion 31. 41 are formed through. The spring member 234 is not necessarily exposed to the outside. For example, a recess for receiving the spring member 234 may be formed on the surface of each clamping part facing the connector 200 to prevent interference between each clamping part and the spring member 234.

第一挟持部材20の長手方向の他端部21bには、第二挟持部31との対向面から第二挟持部31に向けてコネクタストッパ60が突出形成されている。コネクタストッパ60の上面は、コネクタ200の下端が当接する当接面である。
ナット233をボルト231に締結する際に、間接ラチェットをボルト231の軸周りに回転させることから、コネクタ200には一時的に押し下げる力が働く。このような力が加わったとき、コネクタストッパ60がコネクタ200の下端を支持することにより、コネクタ200の姿勢を安定させて、ナット233の締結作業を容易に行えるようにする。
コネクタストッパ60は、容易には変形しない程度の剛性を有した金属、樹脂等から構成される。コネクタストッパ60は、第一挟持部材20と一体成形されてもよいし、別体として構成された部品を後に一体化させたものでもよい。
なお、コネクタストッパ60は、第二の実施形態に示すように、ベース10の一面10a(上面)から上方に突出させた構成としてもよい。
A connector stopper 60 protrudes from the surface facing the second clamping part 31 toward the second clamping part 31 at the other end part 21 b in the longitudinal direction of the first clamping member 20. The upper surface of the connector stopper 60 is a contact surface with which the lower end of the connector 200 contacts.
When the nut 233 is fastened to the bolt 231, the indirect ratchet is rotated around the axis of the bolt 231. When such a force is applied, the connector stopper 60 supports the lower end of the connector 200, thereby stabilizing the posture of the connector 200 and facilitating the fastening operation of the nut 233.
The connector stopper 60 is made of a metal, resin, or the like having a rigidity that does not easily deform. The connector stopper 60 may be integrally formed with the first clamping member 20 or may be a component that is separately integrated later.
The connector stopper 60 may be configured to protrude upward from one surface 10a (upper surface) of the base 10, as shown in the second embodiment.

コネクタ支持具の使用方法について説明する。
コネクタ200に、柱上変圧器から引き出された引下線W2を接続する。引下線挿通穴232内に引下線W2の先端部を挿通し、引下線挿通穴232から露出した引下線W2の先端部を折り返して、引下線W2が引下線挿通穴232から離脱しないようにする。
コネクタ200に支持具1を装着する。操作部35を操作して第二挟持部31を第一挟持部21から離間させ、第一挟持部21と第二挟持部31との間にコネクタ200を挿入し、第一挟持部21と第二挟持部31とによって第一挟圧片210と第二挟圧片220を挟持した状態とする。このとき、第一開口23からナット233を露出させ、第二開口37からボルト231の頭部231a及び引下線W2を露出させる。なお、この段階で引下線W2は充電されていないため、この作業は素手で行ってよい。
続いて、絶縁ヤットコ250を用いて二人の作業員により引下線W2を高圧線W1に1回だけ巻き付ける(図5参照)。なお、高圧線W1は活線状態であるので、以降の作業は絶縁ヤットコ等を使用した間接活線工法により行う。引下線W2を高圧線W1に巻き付けた後、支持具1は重心のある把持部50側が下方となるように引下線W2周りに回動してその姿勢が安定する。
一人の作業員が絶縁ヤットコ250にて把持部50を把持し、挟圧部211、221間に高圧線W1が挿入されるようにコネクタ200を移動させる。もう一人の作業員が間接ラチェットを用いてナット233をボルト231に締結し、挟圧部211、221にて高圧線W1を挟圧する。
間接ラチェットの使用時には、絶縁ヤットコ250をヤットコストッパ53に当接させて支持具1を上方に押し上げておくようにすれば、コネクタ200が高圧線W1から離間することはない。また、コネクタ200に対して下向きの力が加わったとしても、コネクタ200はコネクタストッパ60よりも下方に移動しないため、その姿勢を安定させた状態にて締結作業を進めることができる。
最後に、把持部50と操作部35とを絶縁ヤットコ250にて同時に挟持することにより、第二挟持部31をボルト231の頭部231aから離間させる。そして、支持具1を下方に移動させれば、ナット233が第一開口23に沿って移動し、支持具1をスムーズにコネクタ200から取り外すことができる。
A method of using the connector support will be described.
The connector 200 is connected to the underline W2 drawn from the pole transformer. The tip of the underline W2 is inserted into the underline insertion hole 232, and the tip of the underline W2 exposed from the underline insertion hole 232 is folded back so that the underline W2 is not detached from the underline insertion hole 232. .
The support tool 1 is attached to the connector 200. The operation unit 35 is operated to move the second clamping unit 31 away from the first clamping unit 21, and the connector 200 is inserted between the first clamping unit 21 and the second clamping unit 31. The first sandwiching piece 210 and the second sandwiching piece 220 are sandwiched by the two sandwiching portions 31. At this time, the nut 233 is exposed from the first opening 23, and the head 231a and the underline W2 of the bolt 231 are exposed from the second opening 37. Since the underline W2 is not charged at this stage, this operation may be performed with bare hands.
Subsequently, the underline W2 is wound around the high-voltage line W1 only once by two workers using the insulating Yatco 250 (see FIG. 5). In addition, since the high voltage line W1 is in a live line state, the subsequent operations are performed by an indirect hot line method using an insulating jacket or the like. After the draw line W2 is wound around the high voltage line W1, the support 1 is rotated around the draw line W2 so that the gripping portion 50 side having the center of gravity is located downward, and the posture is stabilized.
One worker grips the gripping part 50 with the insulating Yatco 250, and moves the connector 200 so that the high-voltage line W1 is inserted between the clamping parts 211 and 221. Another worker fastens the nut 233 to the bolt 231 using an indirect ratchet, and clamps the high-pressure line W1 by the clamping units 211 and 221.
When the indirect ratchet is used, the connector 200 will not be separated from the high-voltage line W1 if the support tool 1 is pushed upward by bringing the insulating jacket 250 into contact with the jacket stopper 53. Even if a downward force is applied to the connector 200, the connector 200 does not move below the connector stopper 60, so that the fastening operation can proceed with the posture stabilized.
Finally, the gripping unit 50 and the operation unit 35 are simultaneously clamped by the insulating jacket 250, thereby separating the second clamping unit 31 from the head 231 a of the bolt 231. And if the support tool 1 is moved below, the nut 233 will move along the first opening 23, and the support tool 1 can be removed from the connector 200 smoothly.

以上のように本実施形態によれば、絶縁ヤットコにて把持可能な把持部を備えたので、支持具が接続された引下線を高圧線に巻き付けた後であっても、支持具を容易に操作することができる。また、把持部と操作部とを絶縁ヤットコにて同時に挟持するという簡単な操作で、一方の挟持部が他方の挟持部に対して洗濯バサミ状に開閉するようにしたので、支持具の取り外しが容易であり、作業性が向上する。   As described above, according to the present embodiment, since the gripping portion that can be gripped by the insulating jacket is provided, the support tool can be easily mounted even after the underline to which the support tool is connected is wound around the high-voltage line. Can be operated. In addition, since the holding part is opened and closed like a clothespin with respect to the other holding part by a simple operation of holding the holding part and the operating part at the same time with an insulating jacket, it is possible to remove the support tool. It is easy and the workability is improved.

〔第二の実施形態〕
本発明の第二の実施形態に係るコネクタ支持具について図3に基づいて説明する。図3は、本発明の第二の実施形態に係る引下線用コネクタ支持具の使用状態を示す正面図である。本実施形態に係るコネクタ支持具は、第一挟持部材を第二挟持部材と同様にベースによって回動自在に支持した点に特徴がある。以下、第一の実施形態と同一の構成には同一の符号を付してその説明を省略する。
第一挟持部材70は、一端部に第一挟圧片210の外側面に添設されることにより第二挟持部31との間で第一挟圧片210及び第二挟圧片220を挟持する第一挟持部21を備え、中間部にベース10によって回動自在に支持された第一軸支部73を備え、他端部に第一軸支部73を中心として第一挟持部21を第二挟持部31に対して開閉動作させる第一操作部75を備えている。
第一挟持部材70は、第二挟持部材30と同様に可動する構成である。また、絶縁ヤットコ250と接触する第一操作部75の表面には、滑止部材76が配置されている。
コネクタストッパ61は、ベース10の一面10a(上面)から上方に突出形成されており、コネクタストッパ61の上面がコネクタ200の下端と当接する当接面である。なお、コネクタストッパ61は第一の実施形態と同様に、第一挟持部21又は第二挟持部31から、他方の挟持部に向けて突出形成したものであってもよい。
本実施形態に係る支持具の使用方法は第一の実施形態と同様であるため、その説明を省略する。
以上のように本実施形態によれば、第二挟持部材30のみならず第一挟持部材20も回動するので、第一挟持部材20と第二挟持部材30を大きく開くことができ、コネクタ200に対して支持具1を着脱する操作が容易となる。
[Second Embodiment]
A connector support according to a second embodiment of the present invention will be described with reference to FIG. FIG. 3: is a front view which shows the use condition of the connector support tool for underlining which concerns on 2nd embodiment of this invention. The connector support according to the present embodiment is characterized in that the first holding member is rotatably supported by the base in the same manner as the second holding member. Hereinafter, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
The first sandwiching member 70 is attached to the outer surface of the first sandwiching piece 210 at one end portion so as to sandwich the first sandwiching piece 210 and the second sandwiching piece 220 with the second sandwiching portion 31. The first pinching portion 21 is provided, the first shaft support portion 73 is rotatably supported by the base 10 at the intermediate portion, and the first pinching portion 21 is the second pinion centered on the first shaft support portion 73 at the other end portion. A first operation unit 75 that opens and closes the holding unit 31 is provided.
The first clamping member 70 is configured to move similarly to the second clamping member 30. Further, a non-slip member 76 is disposed on the surface of the first operation portion 75 that comes into contact with the insulating Yatco 250.
The connector stopper 61 protrudes upward from one surface 10 a (upper surface) of the base 10, and the upper surface of the connector stopper 61 is a contact surface that contacts the lower end of the connector 200. As in the first embodiment, the connector stopper 61 may be formed so as to protrude from the first clamping part 21 or the second clamping part 31 toward the other clamping part.
Since the usage method of the support according to this embodiment is the same as that of the first embodiment, the description thereof is omitted.
As described above, according to the present embodiment, not only the second clamping member 30 but also the first clamping member 20 is rotated, so that the first clamping member 20 and the second clamping member 30 can be greatly opened, and the connector 200. On the other hand, the operation of attaching and detaching the support 1 becomes easy.

〔挟持部の変形実施形態〕
第一挟持部と第二挟持部の変形例について図4に基づいて説明する。図4(a)〜(c)は、第一挟持部と第二挟持部の変形例を示した側面図である。
第一挟持部21は、図2のB矢視図に示す形状の他にも、図2のA矢視図に示された第二挟持部31と同様の形状とすることができる。
また、第一挟持部21は図4(a)に示すように、第一挟持部21の長手方向の一端縁21aを切り欠いた凹状の切欠きとしての第一開口23と、スリット状のバネ部材露出穴25とを連結、一体化して1つの切欠きを形成した概略U字形状とすることができる。或いは、第一挟持部21は、図4(b)に示すように、ナット233の一方の側部(図ではナット233の右側のみ)に沿って伸びる片腕形状とすることができる。或いは、図4(c)に示すように、第一開口23を第一挟持部21の面内に貫通形成した穴としてよい。この場合、第一挟持部21の長手方向一端部側には、ナット233に係止される係止部27が形成される。また、図4(c)に示す第一開口23とバネ部材露出穴25とを連結、一体化させてもよい。
[Modified Embodiment of Nipping Portion]
A modified example of the first clamping unit and the second clamping unit will be described with reference to FIG. 4A to 4C are side views showing modifications of the first clamping unit and the second clamping unit.
In addition to the shape shown in the B arrow view of FIG. 2, the first clamping portion 21 can have the same shape as the second clamping portion 31 shown in the A arrow view of FIG. 2.
Further, as shown in FIG. 4A, the first clamping part 21 includes a first opening 23 as a concave notch formed by cutting out one end edge 21a in the longitudinal direction of the first clamping part 21, and a slit-like spring. The member exposure hole 25 can be connected and integrated to form a substantially U-shape in which one notch is formed. Or the 1st clamping part 21 can be made into the one-arm shape extended along one side part (only the right side of the nut 233 in a figure) of the nut 233, as shown in FIG.4 (b). Alternatively, as shown in FIG. 4 (c), the first opening 23 may be a hole formed so as to penetrate in the plane of the first clamping part 21. In this case, a locking portion 27 that is locked to the nut 233 is formed on one end side in the longitudinal direction of the first clamping portion 21. Further, the first opening 23 and the spring member exposure hole 25 shown in FIG. 4C may be connected and integrated.

第二挟持部31は、図2のA矢視図に示す形状の他にも、図2のB矢視図に示された第一挟持部21と同様の形状とすることができる。
また、第二挟持部31は図4(a)に示すように、第二挟持部31の長手方向の一端縁を切り欠いた凹状の切欠きとしての第二開口37とバネ部材露出穴41とを連通させた概略U字形状とすることができる。或いは、第二挟持部31は、図4(b)に示すように、ボルト231の一方の側部(図ではナット233の右側のみ)に沿って伸びる片腕形状とすることができる。或いは、図4(c)に示すように、第二開口37を第二挟持部31の面内に貫通形成した穴としてよい。この場合、第二挟持部31の長手方向一端部側には、ボルト231の頭部231aに係止される係止部39が形成される。また、図4(c)に示す第二開口37と、バネ部材露出穴41とを連結、一体化させてもよい。
The 2nd clamping part 31 can be made into the same shape as the 1st clamping part 21 shown by B arrow view of FIG. 2 other than the shape shown to A arrow view of FIG.
Further, as shown in FIG. 4A, the second clamping part 31 includes a second opening 37 as a concave notch in which one end edge in the longitudinal direction of the second clamping part 31 is cut out, and a spring member exposure hole 41. It can be made into the general U shape which made these communicate. Or the 2nd clamping part 31 can be made into the one-arm shape extended along one side part (only the right side of the nut 233 in a figure) of the volt | bolt 231 as shown in FIG.4 (b). Alternatively, as shown in FIG. 4C, the second opening 37 may be a hole formed so as to penetrate in the plane of the second clamping unit 31. In this case, a locking portion 39 that is locked to the head portion 231 a of the bolt 231 is formed on the one end side in the longitudinal direction of the second clamping portion 31. Further, the second opening 37 shown in FIG. 4C and the spring member exposure hole 41 may be connected and integrated.

更に第二挟持部31は、図4(c)に示す第二開口37の代わりに、第一挟持部21との対向面にボルト231の頭部231a及び引下線W2の先端部を受け入れ可能な凹所を形成してもよい。この場合も、ボルト231の頭部231aには凹所の上部が係止されることになるので、コネクタ200に装着したときの支持具の脱落を防止できる。
何れの場合も、第二挟持部31に関しては、引下線挿通穴232から引き出された引下線W2と干渉しないようにする必要がある。例えば、図2のB矢視図や図4(a)、(c)に示す形状の挟持部を第二挟持部として採用する場合、引下線挿通穴232から引き出された引下線W2を受け入れる凹所を、第二挟圧片220との対向面に形成することが望ましい。
上記各構成は、第一挟持部と第二挟持部とで適宜組み合わせて実施することができるが、少なくとも、第一挟持部と第二挟持部の一方がボルト231の頭部231a又はナット233に係止可能な係止部を備えるようにして、コネクタ200からの脱落を防止するように構成することが望ましい。
Furthermore, the 2nd clamping part 31 can receive the front-end | tip part of the head 231a of the volt | bolt 231 and the draw-down line W2 on the opposing surface with the 1st clamping part 21 instead of the 2nd opening 37 shown in FIG.4 (c). A recess may be formed. Also in this case, since the upper portion of the recess is locked to the head portion 231a of the bolt 231, it is possible to prevent the support from falling off when the bolt is mounted on the connector 200.
In any case, it is necessary to prevent the second holding part 31 from interfering with the underline W2 drawn out from the underline insertion hole 232. For example, in the case of adopting the holding part having the shape shown in the arrow B of FIG. 2 or the shape shown in FIGS. 4A and 4C as the second holding part, the recess that receives the draw line W2 drawn from the draw line insertion hole 232. It is desirable to form the point on the surface facing the second pinching piece 220.
Although each said structure can be implemented combining suitably with a 1st clamping part and a 2nd clamping part, at least one of a 1st clamping part and a 2nd clamping part serves as the head 231a or nut 233 of the bolt 231. It is desirable to provide a locking portion that can be locked to prevent the connector 200 from falling off.

By operating the operation part 35 of the connector support tool 1 for the underline, the second clamping member 30 rotates and the second clamping member 30 opens and closes with respect to the first clamping member 20 like a clothespin. Removal from the underline connector is very easy. Moreover, since the 2nd clamping member 30 is the structure opened and closed like a clothespin, the underline connector support tool can be easily removed from the underline connector.

(第二の実施態様)
引下線用コネクタ200は、第一挟圧片210及び第二挟圧片220の夫々に貫通形成されて互いに連通する第一挿通孔212及び第二挿通孔222と、第二挟圧片220側から第二挿通孔222及び第一挿通孔212に跨がって軸部231bが挿通されると共に第二挟圧片220に対して相対回転を禁止されたボルト231と、第一挟圧片210の第一挿通孔212から突出したボルト231の軸部231bに螺着されるナット233と、を備えている。
