Description

本発明は、ねじ部を備えた軸体を回動させてその先端を電線に当接させ、電線の把持等を行う配電用工具に係り、特に、複数の異なる形状のねじ部を形成することで軸体の粗動及び微動を可能とする配電用工具に関する。   The present invention relates to a power distribution tool for rotating a shaft provided with a threaded portion so that its tip abuts against an electric wire and gripping the electric wire, and in particular, forming a plurality of differently shaped threaded portions. The present invention relates to a power distribution tool that enables coarse and fine movement of a shaft body.

従来、間接活線工具を使用して電線を把持したり、電線に対して機材を取り付けたりする場合には、特開平５−２５２６２７号公報に開示されるような、電線挟持部と、受片と、受片の下方に取り付けられたねじ軸等からなる端末固定具が使用されてきた。このような構成の端末固定具によれば、ねじ軸の下端を間接活線工具の先端に接続した後、間接活線工具を操作してねじ軸を回動させ、受片を電線挟持部に近付けることによって上記の把持等を行うことが可能である。
しかし、ねじ軸に設けられた雄ねじ部は、先端から末端まで比較的短い一定のピッチを有しており、ねじ軸の先端を電線等に当接させてこれを完全に締め付けるまでには、多数回に亘ってねじ軸を回動させることが必要であった。その結果、握力の低下や作業の長時間化を招き、作業者の疲労が増大したり、作業効率が低下したりするという課題があった。さらに、この疲労増大によって、締め付け作業の途中に、電線挟持部が電線から外れて落下し、作業の確実性や安全性を損なう場合があるという課題もあった。
したがって、このような課題を解決するためには、例えば、電線等に対する締め付けを開始する際、ねじ軸を粗動させることにより迅速な締め付けを可能とするとともに、電線等にねじ軸の先端が当接する直前には、ねじ軸を微動させることにより正確な締め付けを可能とする手段が必要となる。
そこで、このような解決手段として、近年、先端工具に関する技術ではないものの、ねじ軸を迅速かつ正確に回動させるための技術が開発されており、それに関して既に考案が開示されている。 Conventionally, when an indirect hot wire tool is used to hold an electric wire or to attach equipment to the electric wire, an electric wire holding portion and a receiving piece as disclosed in JP-A-5-252627 And the terminal fixture which consists of a screw shaft etc. which were attached below the receiving piece has been used. According to the terminal fixture having such a configuration, after connecting the lower end of the screw shaft to the tip of the indirect hot wire tool, the screw shaft is rotated by operating the indirect hot wire tool, and the receiving piece is placed on the electric wire holding portion. The above-described gripping or the like can be performed by approaching.
However, the male thread portion provided on the screw shaft has a relatively short constant pitch from the tip to the end, and many times are required until the tip of the screw shaft is brought into contact with an electric wire or the like and completely tightened. It was necessary to rotate the screw shaft over a number of times. As a result, there has been a problem that the gripping force is reduced and the work is prolonged, and the worker's fatigue is increased or the work efficiency is lowered. Furthermore, due to the increase in fatigue, there is a problem that the wire holding part may come off from the wire and drop during the tightening operation, thereby impairing the reliability and safety of the operation.
Therefore, in order to solve such a problem, for example, when tightening an electric wire or the like is started, the screw shaft is coarsely moved to enable quick tightening, and the tip of the screw shaft is applied to the electric wire or the like. Immediately before the contact, means for enabling accurate tightening by finely moving the screw shaft is required.
Therefore, as a means for solving such a problem, a technique for rapidly and accurately rotating a screw shaft has been developed in recent years, although it is not a technique related to a tip tool.

特許文献１には「測量機回転軸の微動固定装置」という名称で、回転軸の粗微動と細微動を可能とする測量機回転軸の微動固定装置に関する考案が開示されている。
以下、特許文献１に開示された考案について説明する。特許文献１に開示された測量機回転軸の微動固定装置に関する考案は、測量機本体に螺合した微動ネジ筒と、微動ネジ筒に同軸に螺合した微動ツマミと、微動ツマミの微動ネジ筒に対する一方向への回転によって係合し、以後同方向の回転においては微動ツマミと微動ネジ筒とを一体に回転させる第１のストッパ手段と、微動ツマミの微動ネジ筒に対する他方向への回転によって係合し、以後同方向の回転によって微動ツマミと微動ネジ筒とを一体に回転させる第２のストッパ手段と、微動ツマミの微動ネジ筒に対する螺進螺退運動を縮小して測量機の固定軸の軸方向進退運動に変換するとともに微動ツマミと微動ネジ筒の一体の螺進螺退運動をそのまま固定軸の軸方向進退運動に伝達する変換伝達手段と、からなることを特徴とする。
このような特徴を備えた測量機回転軸の微動固定装置においては、微動ツマミを一方向へ回転させると、第１のストッパ手段を介して微動ネジ筒が微動ツマミと一緒に粗動ネジによって螺進し、変換伝達手段によって固定軸が押圧される。また、微動ツマミを他方向へ回転させると、第２のストッパ手段を介して微動ツマミは微動ネジによって螺進し、変換伝達手段によってこの螺進量が縮小され固定軸に伝達される。したがって、視準作業が正確かつ迅速となり、作業性の良い精密測量が可能となる。 Patent Document 1 discloses a device related to a fine movement fixing device for a surveying instrument rotating shaft that enables coarse and fine movement of the rotating shaft under the name of “fine movement fixing apparatus for a rotating shaft of surveying instrument”.
Hereinafter, the device disclosed in Patent Document 1 will be described. The device related to the fine movement fixing device for the rotating shaft of the surveying instrument disclosed in Patent Document 1 is a fine movement screw cylinder screwed into the main body of the surveying instrument, a fine movement knob screwed coaxially with the fine movement screw cylinder, and a fine movement screw cylinder of the fine movement knob. The first stopper means for rotating the fine movement knob and the fine movement screw cylinder integrally in the rotation in the same direction, and the rotation of the fine movement knob with respect to the fine movement screw cylinder in the other direction. A second stopper means for engaging and rotating the fine movement knob and the fine movement screw cylinder integrally by rotation in the same direction thereafter, and the screwing / retraction movement of the fine movement knob with respect to the fine movement screw cylinder is reduced to reduce the fixed shaft of the surveying instrument. And a conversion transmission means for converting the integral screw advance / retract movement of the fine movement knob and the fine movement screw cylinder to the axial advance / retreat movement of the fixed shaft as it is.
In the fine movement fixing device for the rotating shaft of the surveying instrument having such a feature, when the fine movement knob is rotated in one direction, the fine movement screw cylinder is screwed together with the fine movement knob by the coarse movement screw via the first stopper means. The fixed shaft is pressed by the conversion transmission means. When the fine movement knob is rotated in the other direction, the fine movement knob is screwed by the fine movement screw via the second stopper means, and the screwing amount is reduced by the conversion transmission means and transmitted to the fixed shaft. Therefore, collimation work is accurate and quick, and precise surveying with good workability is possible.

実願昭６１−５８８５１号（実開昭６２−１７０５１４号）のマイクロフィルムMicrofilm of Japanese Utility Model No. 61-58851 (Japanese Utility Model Application No. 62-170514)

しかしながら、特許文献１に開示された考案においては、第１及び第２のストッパ手段や変換伝達手段を必要とすることから、構成がやや複雑である。さらに、微動固定装置は、元々測量という精密作業において使用することを目的としていることから、微動ツマミを回動させる操作は手動による微調整を伴って行われる。
これに対し、間接活線工具を介して配電用工具を操作する場合、このような微調整を伴う回動操作を行うことは、通常困難である。したがって、微動固定装置を配電用工具に対し容易に適用することはできない。 However, since the device disclosed in Patent Document 1 requires first and second stopper means and conversion transmission means, the configuration is somewhat complicated. Further, since the fine movement fixing device is originally intended to be used in a precision work such as surveying, an operation for rotating the fine movement knob is performed with manual fine adjustment.
On the other hand, when operating a power distribution tool via an indirect hot wire tool, it is usually difficult to perform a turning operation with such fine adjustment. Therefore, the fine movement fixing device cannot be easily applied to the power distribution tool.

本発明は、このような従来の事情に対処してなされたものであり、構成が簡易であって、かつ間接活線工具を介して容易に操作可能であり、しかも軸体の粗動及び微動を可能とすることで作業者の疲労防止及び作業効率を向上させる配電用工具を提供することを目的とする。   The present invention has been made in response to such a conventional situation, has a simple configuration, can be easily operated through an indirect hot wire tool, and has coarse and fine movements of the shaft body. It is an object of the present invention to provide a power distribution tool that prevents worker fatigue and improves work efficiency.

上記目的を達成するため、請求項１記載の発明に係る配電用工具は、間接活線工具の取付具用先端に取付具を介して装着される配電用工具であって、電線に対して係止可能な屈曲部を有する係止部材と、この係止部材を一端面において支持するとともに、この一端面と他端面に開口する軸孔が穿設される筒状体と、第１の端部が屈曲部の内周側へ対向し、第２の端部が取付具に連結されるとともに、軸孔の内部へ挿入され、この軸孔の長手方向に沿ってスライドする軸体と、を備え、軸孔は、一端面及び他端面寄りに、それぞれ第１及び第２の雌ねじ部が形成され、軸体は、第１の端部及び第２の端部寄りに、第１及び第２の雌ねじ部にそれぞれ螺合する第１及び第２の雄ねじ部が形成され、第１の雄ねじ部のピッチは、第２の雄ねじ部のピッチよりも長く、第１の雄ねじ部が第１の雌ねじ部に螺合する場合は、第２の雄ねじ部が第２の雌ねじ部に螺合しないように構成されることを特徴とする。 In order to achieve the above object, a power distribution tool according to the first aspect of the present invention is a power distribution tool that is attached to the tip of a fixture for an indirect hot wire tool via a fixture, and is associated with an electric wire. A locking member having a bendable portion, a cylindrical body that supports the locking member on one end surface, and is provided with a shaft hole opened on the one end surface and the other end surface, and a first end portion Is opposed to the inner peripheral side of the bent portion, and the second end portion is coupled to the fixture, and is inserted into the shaft hole and slides along the longitudinal direction of the shaft hole. The shaft hole has first and second female thread portions formed near the one end surface and the other end surface, respectively, and the shaft body has the first and second end portions near the first end portion and the second end portion . First and second male threaded portions that are respectively screwed into the female threaded portion are formed, and the pitch of the first male threaded portion is the pitch of the second male threaded portion. Chiyori even longer, when the first male screw portion is screwed into the first female threaded portion, characterized in that the second male threaded portion is configured to not screwed into the second female threaded portion.

このような構成の配電用工具において、第１及び第２の雄ねじ部の「ピッチ」とは、隣り合うねじ山の間隔をいう。また、第１及び第２の雌ねじ部の「ピッチ」も同様に隣り合うねじ山の間隔をいい、これらはそれぞれ第１及び第２の雄ねじ部の「ピッチ」と等しい。
上記構成の配電用工具においては、例えば、係止部材と軸体による電線の挟持を開始する際には、まず屈曲部を電線の上から係止し、次いで筒状体の軸孔の他端面から軸孔に挿入された軸体を、間接活線工具を回動操作することで一方向に回動させると、軸孔に形成された第１の雌ねじ部に対して軸体に形成された第１の雄ねじ部が螺合する。そのため、軸体は、屈曲部の内周側へ向かって軸孔の長手方向に沿ってスライドする。
そして、そのまま軸体のスライドを継続させると、第１の雌ねじ部に対する第１の雄ねじ部の螺合に代わって、軸孔に形成された第２の雌ねじ部に対して軸体に形成された第２の雄ねじ部が螺合し、軸体はさらに屈曲部の内周側へ向かってスライドする。その結果、屈曲部と軸体との間に電線が挟持される。
一方、係止部材と軸体による電線の挟持を解除する際には、前述した方向と逆の方向に間接活線工具を操作して軸体を回動させると、第２の雌ねじ部に対する第２の雄ねじ部の螺合が継続されつつ、軸体は屈曲部の内周側から離隔する方向へスライドする。その結果、屈曲部と軸体との間から電線が自在に取り外される。 In the power distribution tool having such a configuration, the “pitch” of the first and second male screw portions refers to an interval between adjacent screw threads. Similarly, the “pitch” of the first and second female screw portions is the interval between adjacent screw threads, and these are equal to the “pitch” of the first and second male screw portions, respectively.
In the power distribution tool having the above-described configuration, for example, when starting to hold the electric wire between the locking member and the shaft body, the bent portion is first locked from above the electric wire, and then the other end surface of the shaft hole of the cylindrical body When the shaft inserted into the shaft hole is rotated in one direction by rotating the indirect live tool, the shaft is formed on the shaft relative to the first female screw portion formed in the shaft hole. The first male screw part is screwed. Therefore, the shaft body slides along the longitudinal direction of the shaft hole toward the inner peripheral side of the bent portion.
Then, if the slide of the shaft body is continued as it is, the shaft body is formed with respect to the second female screw portion formed in the shaft hole instead of screwing the first male screw portion to the first female screw portion. The second male screw portion is screwed together, and the shaft body slides further toward the inner peripheral side of the bent portion. As a result, the electric wire is sandwiched between the bent portion and the shaft body.
On the other hand, when releasing the holding of the electric wire between the locking member and the shaft body, if the shaft body is rotated by operating the indirect hot wire tool in the direction opposite to the above-described direction, the second female thread portion is The shaft body slides in a direction away from the inner peripheral side of the bent portion while the screwing of the two male screw portions is continued. As a result, the electric wire is freely removed from between the bent portion and the shaft body.

また、第１の雄ねじ部のピッチは、この第２の雄ねじ部のピッチよりも長いことから、１回の回動当たりに軸体がスライドする距離は、第１の雌ねじ部に対し第１の雄ねじ部が螺合する場合の方が、第２の雌ねじ部に対し第２の雄ねじ部が螺合する場合よりも長い。したがって、軸体のスライドを開始した際、軸体は粗動し、屈曲部と軸体との間に電線が挟持される直前及びこの挟持が解除された直後には、軸体は微動する。
さらに、第１の雄ねじ部のピッチが第２の雄ねじ部のピッチよりも長い場合では、第１の雄ねじ部が第１の雌ねじ部に螺合すると同時に、第２の雄ねじ部が第２の雌ねじ部に螺合すると、軸体の回動が不可能となることから、第１の雄ねじ部が第１の雌ねじ部に螺合する場合は、第２の雄ねじ部が第２の雌ねじ部に螺合しないように構成されることが必要となる。 In addition, since the pitch of the first male screw portion is longer than the pitch of the second male screw portion, the distance that the shaft body slides per one rotation is the first distance relative to the first female screw portion. The case where the male screw part is screwed is longer than the case where the second male screw part is screwed to the second female screw part. Accordingly, when the shaft body starts to slide, the shaft body coarsely moves, and the shaft body slightly moves immediately before and after the electric wire is sandwiched between the bent portion and the shaft body.
Further, when the pitch of the first male screw portion is longer than the pitch of the second male screw portion, the first male screw portion is screwed into the first female screw portion, and at the same time, the second male screw portion is the second female screw. When the first male screw portion is screwed to the first female screw portion, the second male screw portion is screwed to the second female screw portion. It is necessary to be configured not to match.

次に、請求項２記載の発明は、請求項１記載の配電用工具において、第２の雄ねじ部のリード角は、第１の雄ねじ部のリード角よりも小であることを特徴とする。
このような構成の配電用工具において、「リード角」とはねじ面の傾斜を表す角度である。
上記構成の配電用工具においては、請求項１記載の発明の作用に加えて、第１及び第２の雄ねじ部の各ねじ面の摩擦係数が同等であり、第１の雄ねじ部にかかる荷重と第２の雄ねじ部にかかる荷重がほぼ同等の場合に、第２の雄ねじ部を締め付けるに必要な力の方が、第１の雄ねじ部を締め付けるに必要な力よりも、小さい。すなわち、第２の雄ねじ部の方が第１の雄ねじ部よりも締め付け易い傾向となる。
また、上記の条件下では、第２の雄ねじ部を緩めるに必要な力の方が、第１の雄ねじ部を緩めるに必要な力よりも、大きい。すなわち、第２の雄ねじ部の方が第１の雄ねじ部よりも緩み難い傾向となる。 Next, according to a second aspect of the present invention, in the power distribution tool according to the first aspect, the lead angle of the second male screw portion is smaller than the lead angle of the first male screw portion.
In the power distribution tool having such a configuration, the “lead angle” is an angle representing the inclination of the thread surface.
In the power distribution tool having the above-described configuration, in addition to the operation of the first aspect of the invention, the friction coefficient of each screw surface of the first and second male screw portions is equivalent, and the load applied to the first male screw portion is When the load applied to the second male screw portion is substantially equal, the force required to tighten the second male screw portion is smaller than the force required to tighten the first male screw portion. That is, the second male screw part tends to be tightened more easily than the first male screw part.
Also, under the above conditions, the force required to loosen the second male screw portion is greater than the force required to loosen the first male screw portion. That is, the second male screw portion tends to be less loose than the first male screw portion.

続いて、請求項３記載の発明は、請求項１又は請求項２記載の配電用工具において、軸孔の長さは、第１の雄ねじ部の末端から第２の雄ねじ部の先端までの長さ以下であることを特徴とする。
このような構成の配電用工具においては、請求項１又は請求項２記載の発明の作用に加えて、軸孔に形成された第１の雌ねじ部に第１の雄ねじ部が螺合すると同時に、第２の雌ねじ部に第２の雄ねじ部が螺合するという状態が回避されるため、第１の雌ねじ部に対する第１の雄ねじ部の螺合と、第２の雌ねじ部に対する第２の雄ねじ部の螺合と、が互いに独立して行われる。したがって、軸体の粗動と微動とが交互に可能となる。 Subsequently, the invention according to claim 3 is the power distribution tool according to claim 1 or 2, wherein the length of the shaft hole is the length from the end of the first male screw portion to the tip of the second male screw portion. Or less.
In the power distribution tool having such a configuration, in addition to the operation of the invention according to claim 1 or 2, the first male screw portion is screwed into the first female screw portion formed in the shaft hole, Since a state in which the second male screw portion is screwed into the second female screw portion is avoided, the first male screw portion is screwed with the first female screw portion, and the second male screw portion is with respect to the second female screw portion. Are screwed in independently of each other. Therefore, coarse movement and fine movement of the shaft body can be alternately performed.

そして、請求項４記載の発明は、請求項１乃至請求項３のいずれか１項に記載の配電用工具において、筒状体は、第１の雌ねじ部と第２の雌ねじ部との境界付近において、軸孔の表面に開口部が開口するとともに、この開口部の反対側に奥部が設けられる複数の孔部と、この複数の孔部にそれぞれ収容される可動部材と、を備え、複数の孔部は、軸孔の長軸を中心として一定角度毎に配置され、可動部材は、開口部を通過して軸体に接近又は軸体から離隔する可動端部と、一端がこの可動端部に連結されるとともに他端が奥部の付近に固着され、可動端部を軸体に接近させる方向に付勢する弾性体と、からなることを特徴とする。
このような構成の配電用工具においては、請求項１乃至請求項３のいずれか１項に記載の発明の作用に加えて、弾性体が可動端部を軸体に接近させる方向に付勢することから、常に、可動端部が軸体に側方から接触することとなる。すなわち、軸体の表面が複数の可動部材によって均等に押圧され、軸孔に対して軸体が傾斜することが防止される。 According to a fourth aspect of the present invention, in the power distribution tool according to any one of the first to third aspects, the cylindrical body is in the vicinity of the boundary between the first female screw portion and the second female screw portion. The surface of the shaft hole has an opening, and a plurality of holes provided on the opposite side of the opening, and movable members respectively accommodated in the holes. The holes are arranged at fixed angles with the long axis of the shaft hole as a center, and the movable member passes through the opening and approaches the shaft body or is separated from the shaft body, and one end of the movable end. And an elastic body that is connected to the portion and has the other end fixed in the vicinity of the back portion and biases the movable end portion in a direction to approach the shaft body.
In the power distribution tool having such a configuration, in addition to the operation of the invention according to any one of claims 1 to 3, the elastic body biases the movable end portion in a direction to approach the shaft body. Therefore, the movable end always comes into contact with the shaft body from the side. That is, the surface of the shaft body is evenly pressed by the plurality of movable members, and the shaft body is prevented from being inclined with respect to the shaft hole.

そして、請求項５記載の発明は、請求項３記載の配電用工具において、筒状体は、第１の雌ねじ部と第２の雌ねじ部との境界付近において、軸孔の表面に開口部が開口するとともに、この開口部の反対側に奥部が設けられる複数の孔部と、この複数の孔部にそれぞれ収容される可動部材と、を備え、複数の孔部は、軸孔の長軸を中心として一定角度毎に配置され、可動部材は、開口部を通過して軸体に接近又は軸体から離隔する可動端部と、一端がこの可動端部に連結されるとともに他端が奥部の付近に固着され、可動端部を軸体に接近させる方向に付勢する弾性体と、からなり、軸体は、第１の雄ねじ部の末端と第２の雄ねじ部の先端の間に体部が形成され、この体部は、可動端部が係合可能な複数の係合溝が、その長手方向に沿って並列して形成されることを特徴とする。
このような構成の配電用工具においては、請求項３，４記載の発明の作用に加えて、複数の係合溝に可動端部が係合されるため、第１の雄ねじ部の第１の雌ねじ部に対する螺合と、第２の雄ねじ部の第２の雌ねじ部に対する螺合と、がそれぞれ緩んで、軸体が係止部材から離れる方向に降下することが防止される。また、第１の雄ねじ部の方が第２の雄ねじ部よりもリード角が大であってより緩み易いため、この降下防止作用はより顕著である。 The invention according to claim 5 is the power distribution tool according to claim 3, wherein the cylindrical body has an opening on the surface of the shaft hole in the vicinity of the boundary between the first female screw portion and the second female screw portion. And a plurality of holes provided at the opposite side of the opening, and movable members respectively accommodated in the plurality of holes, wherein the plurality of holes are long axes of shaft holes. The movable member has a movable end portion that passes through the opening and approaches the shaft body or is separated from the shaft body, and one end connected to the movable end portion and the other end at the back. And an elastic body that is fixed in the vicinity of the portion and urges the movable end in a direction to approach the shaft body. The shaft body is between the end of the first male screw portion and the tip of the second male screw portion. A body part is formed, and the body part has a plurality of engaging grooves that can be engaged with the movable end part in parallel along the longitudinal direction thereof. Characterized in that it is formed Te.
In the power distribution tool having such a configuration, in addition to the effects of the third and fourth aspects of the invention, since the movable end portion is engaged with the plurality of engagement grooves, the first male screw portion has the first The threaded engagement with the female threaded portion and the threaded engagement of the second male threaded portion with the second female threaded portion are each loosened to prevent the shaft body from being lowered in the direction away from the locking member. Further, since the first male screw portion has a larger lead angle and is more easily loosened than the second male screw portion, this descent preventing action is more remarkable.

本発明の請求項１記載の配電用工具によれば、間接活線工具を回動するという簡易な操作によって、軸体を屈曲部の内周側へ向かって接近させたり、内周側から離隔させたりすることができる。したがって、例えば、電線等を容易に把持又は把持を解除することができる。
さらに、軸体のスライドを開始した際、軸体は粗動することから、軸体が比較的短い一定のピッチを有している従来技術と比較して、軸体がそれぞれ同じ距離をスライドする場合に必要な回動数を減少させることが可能である。そのため、作業量が減少し、作業者の疲労を軽減することができる。また、屈曲部と軸体との間に電線が挟持される直前等には、軸体は微動することから、より正確に電線等に対し軸体を当接させることが可能であるとともに、この後の過度の締め付けによる電線等の損傷を防止することができる。
また、本請求項記載の配電用工具は、係止部材と、筒状体と、軸体と、からなる簡易な構成である。したがって、本請求項記載の配電用工具を、比較的容易に、かつ安価に製造することができる。 According to the power distribution tool of the first aspect of the present invention, the shaft body is moved closer to the inner peripheral side of the bent portion or separated from the inner peripheral side by a simple operation of rotating the indirect hot wire tool. You can make it. Therefore, for example, the electric wire or the like can be easily grasped or released.
Furthermore, since the shaft body coarsely moves when the shaft body starts to slide, the shaft body slides the same distance as compared with the prior art in which the shaft body has a relatively short constant pitch. It is possible to reduce the number of rotations required in this case. As a result, the amount of work is reduced, and worker fatigue can be reduced. In addition, the shaft body slightly moves immediately before the electric wire is sandwiched between the bent portion and the shaft body, so that the shaft body can be brought into contact with the electric wire etc. more accurately. It is possible to prevent damage to the electric wire or the like due to excessive tightening later.
Moreover, the power distribution tool according to the present invention has a simple configuration including a locking member, a cylindrical body, and a shaft body. Therefore, the power distribution tool described in the claims can be manufactured relatively easily and inexpensively.

次に、本発明の請求項２記載の配電用工具によれば、請求項１記載の発明の効果に加えて、第２の雄ねじ部の方が第１の雄ねじ部よりも締め付け易いと同時に緩み難い傾向となるため、軸体のスライドを開始した際、すなわち、作業者が疲労していない時点では、強い力で軸体を回動させ、屈曲部と軸体との間に電線が挟持される直前、すなわち、作業者が疲労してきた時点では弱い力で軸体を回動させるという作業方法が可能となる。また、作業者が疲労してきたために、軸体をゆっくりと回動させる場合であっても、第２の雄ねじ部が緩み難いので、軸体が下方に降下することを防止することができる。   Next, according to the power distribution tool according to claim 2 of the present invention, in addition to the effect of the invention according to claim 1, the second male screw part is easier to tighten than the first male screw part and loosens at the same time. As the shaft body starts to slide, that is, when the worker is not fatigued, the shaft body is rotated with a strong force, and the electric wire is sandwiched between the bent portion and the shaft body. Immediately before starting, that is, when the worker is tired, a working method of rotating the shaft body with a weak force becomes possible. In addition, since the operator is tired, even if the shaft body is slowly rotated, the second male thread portion is difficult to loosen, so that the shaft body can be prevented from descending downward.

本発明の請求項３記載の配電用工具によれば、請求項１又は請求項２に記載の発明の効果に加えて、第１及び第２の雌ねじ部にそれぞれ第１及び第２の雄ねじ部が同時に螺合する状態が回避されることから、軸体が軸孔に沿ってスライドすることが可能になる。したがって、軸体の粗動及び微動を可能とすることで作業者の疲労防止等を図るという本発明の課題を解決することができる。   According to the power distribution tool according to claim 3 of the present invention, in addition to the effects of the invention according to claim 1 or 2, the first and second male thread portions are respectively provided in the first and second female thread portions. Since the state where both are screwed at the same time is avoided, the shaft body can slide along the shaft hole. Therefore, it is possible to solve the problem of the present invention that prevents the operator from fatigue by enabling coarse and fine movement of the shaft.

本発明の請求項４記載の配電用工具によれば、請求項１乃至請求項３のいずれか１項に記載の発明の効果に加えて、軸孔に対して軸体が傾斜することが防止されるため、第１の雌ねじ部から第１の雄ねじ部が屈曲部へ向かって抜け出した直後に、第２の雌ねじ部に対し第２の雄ねじ部を確実に螺合させることが可能である。   According to the power distribution tool according to claim 4 of the present invention, in addition to the effect of the invention according to any one of claims 1 to 3, the shaft body is prevented from being inclined with respect to the shaft hole. Therefore, immediately after the first male screw portion is pulled out from the first female screw portion toward the bent portion, the second male screw portion can be reliably screwed into the second female screw portion.

本発明の請求項５記載の配電用工具によれば、請求項３，４記載の発明の効果に加えて、第１及び第２の雄ねじ部が緩むことが防止されるので、電線等を把持する場合の作業効率が良好となるとともに、電線等を締め付けた後に軸体が自然に降下し電線等が落下する事態を回避することができる。

According to the power distribution tool of the fifth aspect of the present invention, in addition to the effects of the third and fourth aspects of the invention, the first and second male screw portions are prevented from loosening, so that the electric wire or the like is gripped.

本発明の第１の実施の形態に係る配電用工具について、図１乃至図３を用いて詳細に説明する。図１（ａ）は本発明の第１の実施例に係る配電用工具の側面図であり、図１（ｂ）は図１（ａ）におけるＡ方向矢視図である。
図１（ａ）及び図１（ｂ）に示すように、本発明の第１の実施例に係る配電用工具１は、間接活線工具５０の先端５０ａに取付具５１を介して装着される配電用工具であって、電線５２に対して係止可能な屈曲部３を有する係止部材２と、この係止部材２を端面４ａにおいて支持するとともに、この端面４ａと端面４ｂに開口する軸孔５が穿設される筒状体４と、端部６ａが屈曲部３の内周側３ａへ対向し、端部６ｂが取付具５１に連結されるとともに、軸孔５の内部へ挿入され、この軸孔５の長手方向に沿ってスライドする軸体６と、を備える。
軸孔５は、筒状体４の端面４ａ及び端面４ｂ寄りに、それぞれ雌ねじ部７，８が形成される。雌ねじ部７，８のピッチは、それぞれＰ３，Ｐ４であり、ピッチＰ３はピッチＰ４よりも長い。さらに、ねじ山の高さについては雌ねじ部８の方が雌ねじ部７よりも高く、ねじ山の角度については雌ねじ部８の方が雌ねじ部７よりも小さい。
そして、軸体６は、端部６ａ及び端部６ｂ寄りに、雌ねじ部７，８にそれぞれ螺合する雄ねじ部９，１０が形成される。さらに、端部６ａには、電線５２を押圧する押圧部１１が取り付けられる。この押圧部１１は軸体６と共回りする構成である。
また、軸孔５の長さＬ１は、雄ねじ部９の末端から雄ねじ部１０の先端までの長さＬ２と等しい。
なお、間接活線工具５０と軸体６は、いずれも同一の長手方向に沿った中心軸Ｃを有する。 The power distribution tool according to the first embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1A is a side view of a power distribution tool according to the first embodiment of the present invention, and FIG. 1B is a view in the direction of arrow A in FIG.
As shown in FIGS. 1 (a) and 1 (b), the power distribution tool 1 according to the first embodiment of the present invention is attached to the tip 50a of the indirect hot wire tool 50 via a fixture 51. A locking tool 2 having a bent portion 3 that can be locked to the electric wire 52, and a shaft that supports the locking member 2 on the end face 4a and that opens to the end face 4a and the end face 4b. The cylindrical body 4 in which the hole 5 is drilled, the end 6a faces the inner peripheral side 3a of the bent portion 3, the end 6b is connected to the fixture 51, and is inserted into the shaft hole 5. The shaft body 6 slides along the longitudinal direction of the shaft hole 5.
The shaft hole 5 is formed with female thread portions 7 and 8 near the end surface 4a and the end surface 4b of the cylindrical body 4, respectively. The pitches of the female screw portions 7 and 8 are P 3 and P 4 , respectively, and the pitch P 3 is longer than the pitch P 4 . Further, the female screw portion 8 is higher than the female screw portion 7 with respect to the height of the screw thread, and the female screw portion 8 is smaller than the female screw portion 7 with respect to the angle of the screw thread.
The shaft body 6 is formed with male screw portions 9 and 10 that are respectively screwed into the female screw portions 7 and 8 near the end portion 6a and the end portion 6b. Furthermore, the pressing part 11 which presses the electric wire 52 is attached to the end part 6a. The pressing portion 11 is configured to rotate together with the shaft body 6.
The length L 1 of the shaft hole 5 is equal to the length L 2 from the end of the male screw portion 9 to the tip of the male screw portion 10.
The indirect hot wire tool 50 and the shaft body 6 each have a central axis C along the same longitudinal direction.

次に、本実施例の配電用工具を構成する軸体について、図２を用いて詳細に説明する。図２は、本発明の第１の実施例に係る配電用工具を構成する軸体の拡大図である。なお、図１で示した構成要素については、図２においても同一の符号を付して、その説明を省略する。
図２に示すように、軸体６に形成された雄ねじ部９のピッチＰ１は、雄ねじ部１０のピッチＰ２よりも長い。そのため、雄ねじ部９が雌ねじ部７に螺合すると同時に、雄ねじ部１０が雌ねじ部８に螺合すると、軸体６の中心軸Ｃを中心とする回動が不可能となることから、雄ねじ部９が雌ねじ部７に螺合する場合は、雄ねじ部１０が雌ねじ部８に螺合しないように構成されることが必要となる。この構成については、図３において詳細に説明する。
また、ねじ山の高さについては雄ねじ部１０の方が雄ねじ部９よりも高く、ねじ山の角度については雄ねじ部１０の方が雄ねじ部９よりも小さく、また雄ねじ部９の長さと雄ねじ部１０の長さはほぼ等しい。
さらに、雄ねじ部１０のリード角θ２は、雄ねじ部９のリード角θ１よりも小である。具体的には、リード角θ２は５度であり、リード角θ１は２５度である。
なお、雄ねじ部９の有効径ｄ１の長さと雄ねじ部１０の有効径ｄ２の長さの関係は、（ｄ１／ｄ２）＝２／３である。なお、有効径とは、ねじ溝の幅がねじ山の幅に等しくなるような仮想的な円筒の直径である。したがって、雄ねじ部１０のピッチＰ２に対する雄ねじ部９のピッチＰ１の比率Ｋは、約３．６となる。ただし、比率Ｋ＝（Ｐ１／Ｐ２）＝（ｄ１／ｄ２）・［（ｔａｎθ１）／（ｔａｎθ２）］によって算出される。したがって、雄ねじ部９，１０がそれぞれ螺合する雌ねじ部７，８におけるピッチの比率（Ｐ３／Ｐ４）も、約３．６である。 Next, the shaft body constituting the power distribution tool of this embodiment will be described in detail with reference to FIG. FIG. 2 is an enlarged view of a shaft body constituting the power distribution tool according to the first embodiment of the present invention. In addition, about the component shown in FIG. 1, the same code | symbol is attached | subjected also in FIG. 2, and the description is abbreviate | omitted.
As shown in FIG. 2, the pitch P 1 of the male screw portion 9 formed on the shaft body 6 is longer than the pitch P 2 of the male screw portion 10. Therefore, when the male screw portion 9 is screwed into the female screw portion 7 and the male screw portion 10 is screwed into the female screw portion 8, it is impossible to rotate the shaft body 6 around the central axis C. When 9 is screwed into the female screw portion 7, the male screw portion 10 needs to be configured not to screw into the female screw portion 8. This configuration will be described in detail with reference to FIG.
The male thread 10 is higher than the male thread 9 in terms of the height of the thread, and the male thread 10 is smaller than the male thread 9 in terms of the angle of the thread, and the length of the male thread 9 and the male thread. The length of 10 is almost equal.
Further, the lead angle θ 2 of the male screw portion 10 is smaller than the lead angle θ 1 of the male screw portion 9. Specifically, the lead angle θ 2 is 5 degrees and the lead angle θ 1 is 25 degrees.
The relationship of the length of the effective diameter d 2 of the effective diameter d 1 of length and the male screw portion 10 of the external thread portion 9 is (d 1 / d 2) = 2/3. The effective diameter is the diameter of a virtual cylinder whose thread groove width is equal to the thread width. Therefore, the ratio K of the pitch P 1 of the external thread portion 9 to the pitch P 2 of the male thread portion 10 is approximately 3.6. However, the ratio K = (P 1 / P 2 ) = (d 1 / d 2 ) · [(tan θ 1 ) / (tan θ 2 )] is calculated. Therefore, the pitch ratio (P 3 / P 4 ) in the female screw parts 7 and 8 into which the male screw parts 9 and 10 are respectively screwed is also about 3.6.

次に、本実施例の配電用工具の作用について、図３を用いながら詳細に説明する。図３（ａ）乃至図３（ｃ）は、それぞれ本発明の第１の実施例に係る配電用工具を構成する軸体の作用を説明するための側断面図である。なお、図１及び図２で示した構成要素については、図３においても同一の符号を付して、その説明を省略する。
図３（ａ）乃至図３（ｃ）は、いずれも電線５２に係止部材２の屈曲部３が係止され、筒状体４の軸孔５の内部に軸体６が挿入された状態を示している。
このうち、図３（ａ）に示すように、係止部材２と押圧部１１による電線５２の挟持を開始する際には、筒状体４の雌ねじ部７と軸体６の雄ねじ部９が螺合し、押圧部１１と電線５２との間隔Ｈが最大となっている。このとき、間接活線工具５０の中心軸Ｃを中心としてこれをα方向へ回動させると、軸体６が屈曲部３の内周側３ａの方向に向かって上昇する。 Next, the operation of the power distribution tool of this embodiment will be described in detail with reference to FIG. FIG. 3A to FIG. 3C are side sectional views for explaining the operation of the shaft body constituting the power distribution tool according to the first embodiment of the present invention. 1 and 2 are denoted by the same reference numerals in FIG. 3 and description thereof is omitted.
In each of FIGS. 3A to 3C, the bent portion 3 of the locking member 2 is locked to the electric wire 52, and the shaft body 6 is inserted into the shaft hole 5 of the cylindrical body 4. Is shown.
Among these, as shown in FIG. 3A, when the holding of the electric wire 52 by the locking member 2 and the pressing portion 11 is started, the female screw portion 7 of the cylindrical body 4 and the male screw portion 9 of the shaft body 6 are The distance H between the pressing portion 11 and the electric wire 52 is maximized. At this time, when the center axis C of the indirect hot wire tool 50 is rotated in the α direction, the shaft body 6 rises toward the inner peripheral side 3 a of the bent portion 3.

さらに、間接活線工具５０のα方向への回動を継続すると、図３（ｂ）に示すように、雄ねじ部９が端面４ａを通過して雌ねじ部７から完全に抜け出す。なお、軸孔５の長さＬ１は、雄ねじ部９の末端から雄ねじ部１０の先端までの長さＬ２と等しい（図１参照）ため、これと同時に、雄ねじ部１０が端面４ｂを通過して雌ねじ部８への螺合を開始し始める。すなわち、雄ねじ部９の雌ねじ部７に対する螺合と、雄ねじ部１０の雌ねじ部８に対する螺合が同時に起こることが回避される。 Furthermore, when the indirect hot wire tool 50 continues to rotate in the α direction, the male screw portion 9 passes through the end face 4a and completely comes out of the female screw portion 7 as shown in FIG. The length L 1 of the shaft hole 5, for equal from the end of the external thread portion 9 to the length L 2 to the tip of the male screw portion 10 (see FIG. 1), and at the same time, pass the external thread portion 10 is a face 4b Then, the screwing into the female screw portion 8 is started. That is, it is possible to avoid the simultaneous screwing of the male screw portion 9 to the female screw portion 7 and the screwing of the male screw portion 10 to the female screw portion 8.

以降、間接活線工具５０のα方向への回動によって、図３（ｃ）に示すように、押圧部１１が電線５２に当接するとともに、雄ねじ部１０のほぼ全長が雌ねじ部８へ螺合した状態となる。ここで、間接活線工具５０のα方向への回動を停止すると、係止部材２と押圧部１１による電線５２の挟持が完了する。
また、間接活線工具５０をβ方向へ回動させることで、軸体６が電線５２から離隔する方向へ下降し、係止部材２と押圧部１１による電線５２の挟持が解除される。さらに、間接活線工具５０のβ方向への回動を継続することによって、軸体６は図３（ａ）に示される配置に戻る。 Thereafter, as shown in FIG. 3C, the indirect hot wire tool 50 is rotated in the α direction so that the pressing portion 11 comes into contact with the electric wire 52 and the substantially entire length of the male screw portion 10 is screwed into the female screw portion 8. It will be in the state. Here, when the rotation of the indirect hot wire tool 50 in the α direction is stopped, the holding of the electric wire 52 by the locking member 2 and the pressing portion 11 is completed.
Further, by rotating the indirect hot wire tool 50 in the β direction, the shaft body 6 is lowered in a direction away from the electric wire 52, and the holding of the electric wire 52 by the locking member 2 and the pressing portion 11 is released. Furthermore, the shaft body 6 returns to the arrangement shown in FIG. 3A by continuing the rotation of the indirect hot wire tool 50 in the β direction.

続いて、雌ねじ部７に対する雄ねじ部９の作用とを雌ねじ部８に対する雄ねじ部１０の作用を比較しながら説明すると、前述したように、雄ねじ部１０のピッチＰ２に対する雄ねじ部９のピッチＰ１の比率Ｋは、約３．６となることから、１回の間接活線工具５０の回動当たりに、軸体６が中心軸Ｃに沿って移動する長さは、雄ねじ部９の方が雄ねじ部１０の約３．６倍となる。したがって、雄ねじ部９と雌ねじ部７の組み合わせによって軸体６が粗動し、雄ねじ部１０と雌ねじ部８の組み合わせによって軸体６が微動することとなる。
また、雄ねじ部１０のリード角θ２は、雄ねじ部９のリード角θ１よりも小である（図２参照）ために、雄ねじ部９を締め付ける力の方が雄ねじ部１０を締め付ける力よりも強い力が必要となるが、雄ねじ部１０の方が雄ねじ部９よりもそれぞれ雌ねじ部８及び雌ねじ部７に対して緩み難い。よって、図３（ｃ）に示すように、押圧部１１が電線５２に当接した場合に、軸体６が電線５２から離隔する方向へ下降することが防止される。
一方で、図３（ｃ）から図３（ａ）の配置に戻る際には、雄ねじ部９を緩める力の方が雄ねじ部１０を緩める力よりも弱い力で足りる。すなわち、雄ねじ部９の方が雄ねじ部１０よりもそれぞれ雌ねじ部７及び雌ねじ部８に対して緩み易い。
さらに、有効径ｄ１，ｄ２の長さについては雄ねじ部１０の有効径ｄ２の方が雄ねじ部９の有効径ｄ１よりも長く、ねじ山の高さについても雄ねじ部１０の方が雄ねじ部９よりも高い。加えて、雄ねじ部９の長さと雄ねじ部１０の長さはほぼ等しいことから、雄ねじ部９のねじ山にかかるせん断応力は、雄ねじ部１０のねじ山にかかるせん断応力よりも大きくなる傾向にあると考えられる。
なぜなら、［せん断応力］＝［中心軸Ｃ方向に沿った荷重／（π・おねじの山の径・ねじの全長）］，［おねじの山の径］≒［有効径＋ねじ山の高さ］で表わされるからである。したがって、雄ねじ部１０の方が、雄ねじ部９よりも、中心軸Ｃ方向に沿った荷重に対する強度が高いものと考えられる。なお、電線５２を締め付ける最終段階では、雄ねじ部１０が雌ねじ部８に対して螺合しているので、雄ねじ部１０の方が、雄ねじ部９よりも、中心軸Ｃ方向に沿った荷重に対する強度が高いことは、配電用工具１の破損防止という点で、特に有効である。 Subsequently, the operation of the male screw portion 9 with respect to the female screw portion 7 will be described while comparing the action of the male screw portion 10 with respect to the female screw portion 8. As described above, the pitch P 1 of the male screw portion 9 with respect to the pitch P 2 of the male screw portion 10. Since the ratio K is about 3.6, the length that the shaft body 6 moves along the central axis C per one rotation of the indirect hot tool 50 is greater in the male screw portion 9. This is about 3.6 times the male threaded portion 10. Therefore, the shaft body 6 is coarsely moved by the combination of the male screw portion 9 and the female screw portion 7, and the shaft body 6 is finely moved by the combination of the male screw portion 10 and the female screw portion 8.
In addition, since the lead angle θ 2 of the male screw portion 10 is smaller than the lead angle θ 1 of the male screw portion 9 (see FIG. 2), the force that tightens the male screw portion 9 is greater than the force that tightens the male screw portion 10. Although a strong force is required, the male screw portion 10 is less likely to loosen with respect to the female screw portion 8 and the female screw portion 7 than the male screw portion 9, respectively. Therefore, as shown in FIG. 3C, when the pressing portion 11 comes into contact with the electric wire 52, the shaft body 6 is prevented from descending in a direction away from the electric wire 52.
On the other hand, when returning from the arrangement of FIG. 3C to the arrangement of FIG. 3A, the force for loosening the male screw portion 9 is sufficient to be weaker than the force for loosening the male screw portion 10. That is, the male screw portion 9 is more easily loosened than the male screw portion 10 with respect to the female screw portion 7 and the female screw portion 8, respectively.
Furthermore, the effective diameters d 1 and d 2 are longer than the effective diameter d 1 of the male screw portion 9 in terms of the effective diameter d 2 of the male screw portion 10, and the male screw portion 10 is also higher in terms of the thread height. It is higher than the male screw part 9. In addition, since the length of the male screw portion 9 and the length of the male screw portion 10 are substantially equal, the shear stress applied to the thread of the male screw portion 9 tends to be larger than the shear stress applied to the screw thread of the male screw portion 10. it is conceivable that.
Because [shear stress] = [load in the direction of the central axis C / (π · diameter of male thread / total length of thread)], [diameter of male thread] ≈ [effective diameter + high thread height] This is because it is expressed by Therefore, the male screw portion 10 is considered to have higher strength against the load along the direction of the central axis C than the male screw portion 9. In the final stage of tightening the electric wire 52, the male screw portion 10 is screwed with the female screw portion 8. Therefore, the male screw portion 10 is stronger than the male screw portion 9 with respect to the load along the central axis C direction. High is particularly effective in terms of preventing damage to the power distribution tool 1.

以上説明したように、本実施例に係る配電用工具１によれば、雄ねじ部９と雌ねじ部７、及び雄ねじ部１０と雌ねじ部８を備えることと、軸孔５の長さＬ１が軸体６の長さＬ２と等しいことにより、軸体６の粗動と微動とが交互に可能となる。より詳細には、電線５２の挟持を開始する際には、粗動によって押圧部１１を電線５２に接近させ、押圧部１１が電線５２に当接する直前には、ゆっくりと精密な動きによって電線５２に押圧部１１を当接させることが可能となる。よって、配電用工具１を使用することで、電線５２を損傷させることなく迅速かつ正確に把持することができる。
ただし、雄ねじ部９を締め付ける力の方が雄ねじ部１０を締め付ける力よりも強い力が必要となる。しかし、このような場合は、間接活線工具５０の回動を開始した直後であるため、作業者の疲労がなく、作業者の負担はそれほど重いものではないものと考えられる。また、図３（ｃ）に示すように、電線５２に押圧部１１が当接する直前に、リード角θ２の小さい雄ねじ部１０が雌ねじ部８に螺合しているので、小さい力で雄ねじ部１０を締め付けることができる。このように、配電用工具１によれば、電線５２の把持作業が完了する間際において、作業者の疲労を抑制することが可能である。
また、本実施例に係る配電用工具１は、係止部材２と、筒状体４と、軸体６と、からなる簡易な構成である。このうち、軸体６にはそれぞれピッチの異なる雄ねじ部９，１０を形成し、筒状体４にはこれらがそれぞれ螺合する雌ねじ部７，８を形成することが必要であるが、このような雄ねじ部９，１０や雌ねじ部７，８は、例えばダイスやタップといった金属加工用工具を使用した従来技術により形成される。したがって、配電用工具１を、比較的容易に、かつ安価に製造することができる。 As described above, according to the distribution tool 1 according to the present embodiment, and comprise a male screw portion 9 and the female screw portion 7 and the external thread portion 10 and the internal thread portion 8, the length L 1 of the shaft hole 5 is axial by equal to the length L 2 of the body 6, a fine movement and rough movement of the shaft 6 is made possible alternately. More specifically, when the clamping of the electric wire 52 is started, the pressing portion 11 is brought close to the electric wire 52 by coarse movement, and immediately before the pressing portion 11 contacts the electric wire 52, the electric wire 52 is slowly and precisely moved. It becomes possible to make the pressing part 11 contact. Therefore, by using the power distribution tool 1, the electric wire 52 can be quickly and accurately gripped without being damaged.
However, the force for tightening the male screw portion 9 requires a stronger force than the force for tightening the male screw portion 10. However, in such a case, since it is immediately after the indirect hot wire tool 50 starts to rotate, it is considered that there is no fatigue of the worker and the burden on the worker is not so heavy. Further, as shown in FIG. 3 (c), immediately before the pressing portion 11 abuts against the wire 52, since the smaller external thread portion 10 of the lead angle theta 2 is screwed into the internal thread portion 8, externally threaded portion with a small force 10 can be tightened. Thus, according to the power distribution tool 1, it is possible to suppress the worker's fatigue just before the gripping operation of the electric wire 52 is completed.
Moreover, the power distribution tool 1 according to the present embodiment has a simple configuration including a locking member 2, a cylindrical body 4, and a shaft body 6. Of these, it is necessary to form male threaded portions 9 and 10 having different pitches on the shaft body 6 and to form female threaded portions 7 and 8 into which the cylindrical body 4 is screwed. The male screw portions 9 and 10 and the female screw portions 7 and 8 are formed by a conventional technique using a metal working tool such as a die or a tap. Therefore, the power distribution tool 1 can be manufactured relatively easily and inexpensively.

なお、本実施例に係る配電用工具１は本実施例に示すものに限定されない。例えば、雄ねじ部９，１０や雌ねじ部７，８のピッチ、リード角及び有効径は、前述したものに限定されない。より詳細には、軸孔５の長さＬ１は、雄ねじ部９の末端から雄ねじ部１０の先端までの長さＬ２より短くても良い。さらに、雄ねじ部９の有効径の長さは、押圧部１１が雌ねじ部７を通過して落下しない程度に、雄ねじ部１０の有効径の長さ以上であっても良い。このほか、押圧部１１が軸体６と共回りしない構成であっても良い。 In addition, the power distribution tool 1 according to the present embodiment is not limited to that shown in the present embodiment. For example, the pitch, lead angle, and effective diameter of the male screw portions 9 and 10 and the female screw portions 7 and 8 are not limited to those described above. More specifically, the length L 1 of the shaft hole 5 may be shorter than the length L 2 from the end of the male screw portion 9 to the tip of the male screw portion 10. Furthermore, the length of the effective diameter of the male screw portion 9 may be equal to or longer than the effective diameter of the male screw portion 10 so that the pressing portion 11 does not fall through the female screw portion 7. In addition, the structure which the press part 11 does not rotate with the shaft body 6 may be sufficient.

本発明の第２の実施の形態に係る配電用工具について、図４乃至図６を用いて詳細に説明する。図４は、本発明の第２の実施例に係る配電用工具を構成する可動部材の側断面図である。なお、図１乃至図３で示した構成要素については、図４においても同一の符号を付して、その説明を省略する。
図４に示すように、本発明の第２の実施例に係る配電用工具１２は、筒状体１３は、雌ねじ部７と雌ねじ部８との境界付近において、軸孔５の表面に開口部１４ａが開口するとともに、この開口部１４ａの反対側に奥部１４ｂが設けられる複数の孔部１４と、この複数の孔部１４にそれぞれ収容される可動部材１５と、を備える。
可動部材１５は、開口部１４ａを通過して軸体６に接近又は軸体６から離隔する球形状の可動端部１６と、一端１７ａがこの可動端部１６に連結されるとともに他端１７ｂが奥部１４ｂの付近に固着され、この可動端部１６を軸体に接近させる方向に付勢する弾性体１７と、からなる。配電用工具１２におけるこれ以外の構成については、実施例１に係る配電用工具１と同様である。 A power distribution tool according to a second embodiment of the present invention will be described in detail with reference to FIGS. FIG. 4 is a side sectional view of a movable member constituting the power distribution tool according to the second embodiment of the present invention. The constituent elements shown in FIGS. 1 to 3 are denoted by the same reference numerals in FIG. 4 and the description thereof is omitted.
As shown in FIG. 4, in the power distribution tool 12 according to the second embodiment of the present invention, the cylindrical body 13 has an opening on the surface of the shaft hole 5 in the vicinity of the boundary between the female screw portion 7 and the female screw portion 8. 14 a has an opening, and includes a plurality of hole portions 14 provided with a back portion 14 b on the opposite side of the opening portion 14 a, and a movable member 15 accommodated in each of the plurality of hole portions 14.
The movable member 15 has a spherical movable end 16 that passes through the opening 14a and approaches or is separated from the shaft body 6, and one end 17a is connected to the movable end 16 and the other end 17b is connected to the movable body 15.

これに対し、図６（ｂ）に示すように、実施例２の第２の変形例に係る配電用工具１２ｂにおいては、軸体６は、雄ねじ部９の末端と雄ねじ部１０の先端の間に体部６ｃが形成される。この体部６ｃは、可動端部１６が係合可能な複数の係合溝１８が、中心軸Ｃに沿って並列して形成される。配電用工具１２ｂにおけるこれ以外の構成については、実施例２に係る配電用工具１２と同様である。 Further, the shaft body 6, the hole 14, and the movable member 15 will be described in more detail with reference to FIG. FIG. 6A is a side sectional view of a cylindrical body and a shaft body constituting a power distribution tool according to a second embodiment of the present invention, and FIG. 6B is a power distribution according to the second modification. It is a sectional side view of the cylindrical body and shaft which comprise the tool for operation. The components shown in FIGS. 1 to 5 are denoted by the same reference numerals in FIG. 6 and the description thereof is omitted.
As shown in FIG. 6A, in the power distribution tool 12 according to the second embodiment, a body portion 6c described later has a columnar shape in which uneven portions and the like are not formed on the surface.
On the other hand, as shown in FIG. 6B, in the power distribution tool 12b according to the second modification of the second embodiment, the shaft body 6 is located between the end of the male screw portion 9 and the tip of the male screw portion 10. The body part 6c is formed. In the body portion 6 c, a plurality of engagement grooves 18 that can be engaged with the movable end portion 16 are formed in parallel along the central axis C. Other configurations of the power distribution tool 12b are the same as those of the power distribution tool 12 according to the second embodiment.

次に、本実施例の配電用工具１２，１２ａ，１２ｂの作用について、詳細に説明する。
本実施例の配電用工具１２，１２ａ，１２ｂにおいては、可動端部１６を軸体に接近させる方向に付勢する弾性体１７によって、可動端部１６は、軸体６の表面に側方から接触する。なお、図４に示すように、可動端部１６が雄ねじ部９のねじ山に接触する際、弾性体１７が収縮するので、可動端部１６は、軸体６のスライドに伴い移動するねじ山を乗り越えることが可能である。すなわち、軸体６の形状や軸体６が軸孔５に対しスライドしている最中か否かに関わらず、可動端部１６の軸体６に対する接触が継続される。
また、図５に示すように、複数の可動部材１５は、軸孔５の長軸Ｄを中心として一定角度毎に配置される複数の孔部１４にそれぞれ収容されるため、それぞれの可動端部１６が軸体６に側方から接触すると、軸体６の中心軸Ｃと軸孔５の長軸Ｄとが一致した状態が保持されつつ、軸体６の表面が複数の可動部材１５によって均等に押圧される。したがって、軸孔５に対して軸体６が傾斜することが防止される。ただし、軸体６に対する可動端部１６の押圧は、軸体６のスライドや回動を阻害する程度に強いものではない。配電用工具１２，１２ａ，１２ｂにおけるこれ以外の作用については、実施例１に係る配電用工具１と同様である。 Next, the operation of the power distribution tools 12, 12a, 12b of this embodiment will be described in detail.
In the power distribution tools 12, 12 a, and 12 b of the present embodiment, the movable end portion 16 is laterally applied to the surface of the shaft body 6 by the elastic body 17 that biases the movable end portion 16 toward the shaft body. Contact. As shown in FIG. 4, the elastic body 17 contracts when the movable end portion 16 comes into contact with the thread of the male screw portion 9, so that the movable end portion 16 is moved by the slide of the shaft body 6. It is possible to get over. That is, the contact of the movable end 16 with the shaft body 6 is continued regardless of the shape of the shaft body 6 and whether or not the shaft body 6 is in the middle of sliding with respect to the shaft hole 5.
Further, as shown in FIG. 5, the plurality of movable members 15 are respectively accommodated in the plurality of hole portions 14 arranged at fixed angles with the long axis D of the shaft hole 5 as the center. When the shaft 16 contacts the shaft body 6 from the side, the state in which the central axis C of the shaft body 6 and the long axis D of the shaft hole 5 coincide with each other is maintained, and the surface of the shaft body 6 is evenly provided by the plurality of movable members 15. Pressed. Therefore, the shaft body 6 is prevented from being inclined with respect to the shaft hole 5. However, the pressing of the movable end portion 16 against the shaft body 6 is not strong enough to prevent the shaft body 6 from sliding or rotating. Other functions of the power distribution tool 12, 12a, 12b are the same as those of the power distribution tool 1 according to the first embodiment.

さらに、本実施例の配電用工具１２ｂにおいては、軸体６の屈曲部３方向へのスライドに伴い、可動端部１６が順次係合溝１８へ係合する。したがって、雄ねじ部１０の雌ねじ部８に対する螺合が緩むことが防止され、軸体６が屈曲部３から離隔する方向へ下降することが防止される。なお、このような作用は、そもそも雄ねじ部９のリード角θ２が５度と小さいことによって発揮されるものであるが、係合溝１８が設けられることによって、さらにこの作用が補強されるものである。また、前述したように、弾性体１７が収縮するので、可動端部１６は、軸体６のスライドに伴い移動する係合溝１８を乗り越えることが可能である。 Furthermore, in the power distribution tool 12b of the present embodiment, the movable end portion 16 is sequentially engaged with the engagement groove 18 as the shaft body 6 slides in the direction of the bent portion 3. Therefore, the screwing of the male screw portion 10 to the female screw portion 8 is prevented from being loosened, and the shaft body 6 is prevented from descending in a direction away from the bent portion 3. In addition, such an action is exhibited when the lead angle θ 2 of the male screw portion 9 is as small as 5 degrees in the first place, but this action is further reinforced by the provision of the engagement groove 18. It is. Further, as described above, since the elastic body 17 contracts, the movable end portion 16 can get over the engaging groove 18 that moves as the shaft body 6 slides.

以上説明したように、本実施例の配電用工具１２，１２ａ，１２ｂによれば、軸孔５に対して軸体６が傾斜することが防止されることから、雌ねじ部７から雄ねじ部９が屈曲部３へ向かって抜け出した直後に、雌ねじ部８に対し雄ねじ部１０を確実に螺合させることが可能である。したがって、雌ねじ部７に対する雄ねじ部９の螺合と、雌ねじ部８に対する雄ねじ部１０の螺合の切り替えを滑らかに行うことができる。   As described above, according to the power distribution tools 12, 12 a, and 12 b of the present embodiment, the shaft body 6 is prevented from inclining with respect to the shaft hole 5. The male screw portion 10 can be reliably screwed into the female screw portion 8 immediately after it is pulled out toward the bent portion 3. Therefore, it is possible to smoothly switch the screwing of the male screw part 9 to the female screw part 7 and the screwing of the male screw part 10 to the female screw part 8.

さらに、本実施例の配電用工具１２ｂによれば、係合溝１８が設けられることによって、雄ねじ部１０の緩み防止効果が補強されるので、電線５２を把持する場合の作業効率が良好となるとともに、電線５２を締め付けた後に軸体６が自然に降下し電線５２が落下する事態を回避することができる。なお、このような落下防止効果は、電線５２の締め付け過程の最終時点で発揮されるため、作業者の疲労軽減という点で、極めて有効である。配電用工具１２，１２ａ，１２ｂにおけるこれ以外の効果については、実施例１に係る配電用工具１と同様である。   Furthermore, according to the power distribution tool 12b of the present embodiment, since the engagement groove 18 is provided, the effect of preventing the loosening of the male screw portion 10 is reinforced, so that the work efficiency when gripping the electric wire 52 is improved. In addition, it is possible to avoid the situation where the shaft body 6 naturally falls after the electric wire 52 is tightened and the electric wire 52 falls. In addition, since such a fall prevention effect is exhibited at the final point of the tightening process of the electric wire 52, it is extremely effective in terms of reducing the worker's fatigue. The other effects of the power distribution tools 12, 12a, 12b are the same as those of the power distribution tool 1 according to the first embodiment.

なお、本実施例に係る配電用工具１２，１２ａ，１２ｂは本実施例に示すものに限定されない。例えば、孔部１４及び可動部材１５は、軸孔５の長軸Ｄを中心として１８０度や１２０度以外の角度ごとに配置されてもよい。また、係合溝１８は、雄ねじ部９寄りの体部６ｃに設けられても良い。この場合、雄ねじ部９の雌ねじ部７に対する螺合が緩むことが防止される。さらに、体部６ｃの全長に亘って設けられても良い。この場合には、体部６ｃの長さが軸孔５の長さよりも長い場合において、軸孔５に対して軸体６が傾斜することが強く防止される。   The power distribution tools 12, 12a, 12b according to the present embodiment are not limited to those shown in the present embodiment. For example, the hole 14 and the movable member 15 may be arranged at every angle other than 180 degrees or 120 degrees with the long axis D of the shaft hole 5 as the center. Further, the engagement groove 18 may be provided in the body portion 6 c near the male screw portion 9. In this case, the screwing of the male screw portion 9 to the female screw portion 7 is prevented from loosening. Furthermore, you may provide over the full length of the body part 6c. In this case, when the length of the body portion 6 c is longer than the length of the shaft hole 5, the shaft body 6 is strongly prevented from being inclined with respect to the shaft hole 5.
