Description

本発明は、電線端末の導電部を覆うことにより電線の端末処理を行う電線端末カバーに関し、特に、線径の異なる電線に対応可能な電線端末カバーに関する。 The present invention relates to a wire end cover that performs wire end processing by covering a conductive portion of a wire end, and more particularly to a wire end cover that can handle wires having different wire diameters.

従来から、引留クランプを用いて電柱に引留固定する高圧絶縁電線の引留部において、引留クランプの把持部より突出する高圧絶縁電線の端末は、電気的絶縁性を確保するために電線端末カバーで覆って保護されている。また、停電作業などで電柱を挟んで両側の引留クランプ間を接続する縁回し線を切断したような際も、その高圧絶縁電線の切断個所の端末は、同じように電線端末カバーで覆って保護されている。 Conventionally, in high-voltage insulated wire holding parts that are fixed to a power pole using a holding clamp, the ends of high-voltage insulated wires protruding from the holding part of the holding clamp are covered with a wire end cover to ensure electrical insulation. Protected. In addition, when cutting off the edge wire that connects between the retaining clamps on both sides with the power pole sandwiched during a power failure, etc., the end of the high-voltage insulated wire is covered with a wire end cover in the same way for protection. Has been.

このような電線端末カバーには、電線を収納可能な収納部を１つ有する電線端末カバー（特許文献１，２参照）や、２以上の異なる電線の線径に対応して複数の収納部を有する電線端末カバー（後述する図１３の例及び特許文献３参照）など様々なものがある。 Such an electric wire terminal cover includes an electric wire terminal cover (see Patent Documents 1 and 2) having one storage portion that can store electric wires, and a plurality of storage portions corresponding to the wire diameters of two or more different electric wires. There are various types such as an electric wire terminal cover (see the example of FIG. 13 and Patent Document 3 described later).

例えば、特許文献１に示す電線端末カバーは、有底筒状の収納部を１つ備え、その収納部の開口部にストッパーが装着されている。特許文献２に示す電線端末カバーは、収納部の内周面に突起が複数中心方向に向けて設けられている。これらの電線端末カバーは、このストッパー又は突起が変位することによって電線の線径に左右されることなく異なる線径の電線に使用できる。 For example, the electric wire terminal cover shown in Patent Document 1 includes one bottomed cylindrical storage portion, and a stopper is attached to the opening of the storage portion. In the electric wire terminal cover shown in Patent Document 2, a plurality of protrusions are provided on the inner peripheral surface of the storage portion toward the center. These electric wire end covers can be used for electric wires having different wire diameters without being influenced by the wire diameter of the electric wires due to displacement of the stoppers or protrusions.

図１３に示す複数の収納部を有する電線端末カバー４００は、有底筒状に形成されており、異なる電線の線径に対応して異なる内径を有する筒状形状の収納部４０１を複数備え、これらの収納部４０１が筒芯方向Ａに沿って開口部４０２から底部４０３に向かって内径が小さくなるように並んで設けられる。このように収納部４０１を配列することにより、電線端末カバー４００は、最も開口部４０２側にある収納部４０１で最も太い線径の電線に対応し、最も底部４０３側の収納部４０１で最も細い線径の電線に対応する。図１３に示す電線端末カバー４００の例は、４つの線径に対応している。また、特許文献３に示す電線端末カバーも同様である。 The wire terminal cover 400 having a plurality of storage portions shown in FIG. 13 is formed in a bottomed cylindrical shape, and includes a plurality of cylindrical storage portions 401 having different inner diameters corresponding to the wire diameters of different wires. These storage portions 401 are provided side by side along the cylinder core direction A so that the inner diameter decreases from the opening 402 toward the bottom 403. By arranging the storage portions 401 in this manner, the wire terminal cover 400 corresponds to the wire having the thickest wire diameter in the storage portion 401 closest to the opening 402 and the thinnest in the storage portion 401 closest to the bottom 403. Corresponds to the wire diameter. The example of the wire end cover 400 shown in FIG. 13 corresponds to four wire diameters. The same applies to the wire terminal cover shown in Patent Document 3.

特開平０８−２０５３７１号公報Japanese Patent Laid-Open No. 08-205371 特開平０９−２３３６６６号公報Japanese Patent Laid-Open No. 09-233666 特開２００３−１４３７４５号公報JP 2003-143745 A

しかし、図１３で示した電線端末カバー４００は、最も開口部４０２側の収納部４０１に対応する線径以下の線径の電線に用いる場合、電線の線径に対応した収納部４０１より開口部４０２側の他の収納部４０１と電線との間に隙間ができる。この隙間は、電線の線径に対応した収納部４０１よりも開口部４０２側の他の収納部４０１の方が電線の線径より大きいために発生する。この隙間から電線端末カバー４００の内部に水が浸入しないように、通常は、電線端末カバー４００の開口部４０２と電線とに跨って絶縁テープが巻かれる。電線と開口部４０２側の収納部４０１との間に隙間が開いたままでは、電線の外周面と電線端末カバー４００の開口部４０２の外周面とに段差が形成され、絶縁テープが巻きにくい。このようなときは、電線の線径に対応した収納部４０１より開口部４０２側の他の収納部４０１を切断し、電線の外周面と電線端末カバー４００の開口部４０２の外周面との段差を下げて使用される。 However, when the wire terminal cover 400 shown in FIG. 13 is used for an electric wire having a wire diameter equal to or smaller than the wire diameter corresponding to the storage portion 401 on the most opening portion 402 side, the opening portion is opened from the storage portion 401 corresponding to the wire diameter of the wire. A gap is formed between the other storage portion 401 on the 402 side and the electric wire. This gap is generated because the other storage portion 401 on the opening 402 side is larger than the wire diameter of the electric wire than the storage portion 401 corresponding to the wire diameter of the electric wire. In order to prevent water from entering the inside of the wire end cover 400 from this gap, the insulating tape is usually wound over the opening 402 of the wire end cover 400 and the wire. If a gap is left between the electric wire and the storage portion 401 on the opening 402 side, a step is formed between the outer peripheral surface of the electric wire and the outer peripheral surface of the opening 402 of the electric wire terminal cover 400, and the insulating tape is difficult to wind. In such a case, the other storage portion 401 on the opening 402 side is cut from the storage portion 401 corresponding to the wire diameter of the wire, and the step between the outer peripheral surface of the wire and the outer peripheral surface of the opening portion 402 of the wire terminal cover 400 is cut. Used with lowered.

更に、この電線端末カバー４００は、電線の端末に対して開口部４０２側を向けて収納部４０１に挿入することによって、電線の端末を覆うものである。収納部４０１に電線の端末を挿入する際、電線の線径に対応した収納部４０１よりも開口部４０２側の他の収納部４０１を切断した後の電線端末カバー４００の収納部４０１と電線との間には、ほとんど隙間が空いていない。電線端末カバー４００は、電線の端末を収納部４０１の底部４０３まで挿入するためには、タイスティックを取り付けた共用操作棒やストレーリングトングなどを用いて底部４０３側から叩くなどして挿入しなければならない。他の収納部４０１を切断して用いる電線端末カバー４００は、その切断面が歪になっていることもあり、更に挿入しにくくなる。電線端末カバー４００を電線の端末に装着する作業は、このように手間のかかるものであった。 Furthermore, the electric wire terminal cover 400 covers the electric wire terminal by inserting the electric wire terminal cover 400 into the housing portion 401 with the opening 402 side facing the electric wire terminal. When inserting the end of the electric wire into the accommodating portion 401, the accommodating portion 401 and the electric wire of the electric wire end cover 400 after cutting the other accommodating portion 401 closer to the opening 402 than the accommodating portion 401 corresponding to the wire diameter of the electric wire There is almost no gap between them. In order to insert the end of the electric wire into the bottom portion 403 of the storage portion 401, the electric wire end cover 400 must be inserted by hitting it from the bottom portion 403 side using a common operation rod attached with a tie stick or a trailing tongue. I must. The electric wire terminal cover 400 that is used by cutting the other storage portion 401 may be distorted in its cut surface, and is more difficult to insert. The work of attaching the wire end cover 400 to the end of the wire is time-consuming as described above.

そこで、本発明は、上述した問題に鑑み、電線の端末を装着しやすくすることにより電線の端末処理の作業性を改善することができる電線端末カバーを提供することを課題とする。 Then, this invention makes it a subject to provide the electric wire terminal cover which can improve the workability | operativity of the terminal processing of an electric wire by making it easy to mount | wear with the terminal of an electric wire in view of the problem mentioned above.

本発明に係る電線端末カバーは、電線の端末を収納可能な略筒形状の収納部を電線の異なる線径ごとに有する電線端末カバーにおいて、第１構成体と、第２構成体と、第１構成体及び第２構成体を開閉自在に連結する連結部とを備え、第１構成体及び第２構成体のそれぞれは、筒芯方向と直交する方向に並んで設けられる複数の分割円筒部であって、それぞれの分割円筒部が第１構成体と第２構成体とが閉じた状態で相手側の対応する分割円筒部と合わさって略筒形状の収納部となる複数の分割円筒部を有し、第１構成体の分割円筒部と第２構成体の分割円筒部の円弧の長さの比率が異なると共に、少なくとも円弧の長さが長い分割円筒部が弾性変形可能に構成されることを特徴とする。 The wire terminal cover according to the present invention includes a first structure, a second structure, and a first structure, each having a substantially cylindrical storage portion that can store the terminal of the wire for each different wire diameter . Bei example a connecting portion for connecting the structure and the second structure openably, each of the first structure and the second structure, the plurality being arranged in the direction orthogonal to the cylinder center direction dividing the cylindrical portion And each of the divided cylindrical portions includes a plurality of divided cylindrical portions that are combined with the corresponding divided cylindrical portions on the other side in a state where the first structural body and the second structural body are closed to form a substantially cylindrical storage portion. And the ratio of the arc lengths of the divided cylindrical portion of the first component and the divided cylindrical portion of the second component is different, and at least the divided cylindrical portion having a long arc length is configured to be elastically deformable. It is characterized by.

かかる構成によれば、収納部が異なる線径の電線に対応して複数設けられており、端末処理が必要な電線の線径に適した収納部を選んで装着することができる。収納部は、第１構成体と第２構成体とが開いた状態では、第１構成体と第２構成体とに分かれて形成される。この第１構成体及び第２構成体のいずれか一方に電線の端末を沿わせる。この状態から、第１構成体と第２構成体とを閉じることにより、電線を沿わせた一方の構成体に他方の構成体が合わさって収納部が形成される。このようにして、電線は、この収納部の内部に収納される。すなわち、従来のように電線端末カバーの筒芯方向から収納部に向けて電線の端末を挿入する必要はなく、電線をその線径に対応した収納部に収納することが容易にできる。よって、電線端末カバーに電線の端末を装着しやすくすることにより電線の端末処理の作業性を改善することができる。
また、第１構成体と第２構成体とに分かれて形成される部分の円弧の長さの比率が異なるため、少なくとも第１構成体及び第２構成体のうち円弧の長さが長い構成体が電線の端末を少なくとも中心角１８０度以上の外周面で覆うことができる。この円弧の長さが長い構成体は、円弧の一端と他端との離間距離が電線の直径より短く形成される。この円弧の長さが長い構成体は、弾性変形可能であるため、この離間距離を拡げる方向に弾性変形させることにより、この円弧の長さが長い構成体に電線の端末を沿わせることができる。円弧の長さの長い構成体がこの状態から弾性変形前に戻ることにより、この円弧の長さの長い構成体に沿わせた電線の端末は、円弧の一端と他端との離間距離が電線の直径より再び短くなるため、電線の端末が抜け落ちるのを防止できる。作業者は、その構成体に電線を沿わせて一方の構成体と他方の構成体とを閉じることによって電線の端末を電線端末カバーに装着するまでの間、電線を保持し続ける必要がなくなる。よって、電線端末カバーに電線の端末を装着しやすくすることにより電線の端末処理の作業性を改善することができる。 According to such a configuration, a plurality of storage units are provided corresponding to electric wires having different wire diameters, and a storage unit suitable for the wire diameter of the electric wires that require terminal processing can be selected and mounted. In the state where the first structure body and the second structure body are opened, the storage portion is formed separately into the first structure body and the second structure body. The terminal of the electric wire is placed along one of the first structure and the second structure. From this state, by closing the first structural body and the second structural body, the other structural body is combined with one structural body along the electric wire to form a storage portion. In this way, the electric wire is stored in the storage unit. That is, it is not necessary to insert the end of the electric wire from the tube core direction of the electric wire end cover toward the accommodating portion as in the conventional case, and the electric wire can be easily accommodated in the accommodating portion corresponding to the wire diameter. Therefore, the workability of the end treatment of the electric wire can be improved by making it easy to attach the end of the electric wire to the electric wire end cover.
Moreover, since the ratio of the length of the arc of the part formed separately in the first structure and the second structure is different, the structure having a long arc length among at least the first structure and the second structure Can cover the end of the electric wire with an outer peripheral surface having a central angle of 180 degrees or more. In the structure having a long arc, the distance between one end and the other end of the arc is shorter than the diameter of the electric wire. Since the structure having a long arc is elastically deformable, the end of the electric wire can be placed along the structure having a long arc by elastically deforming in the direction of increasing the separation distance. . When the long arc-shaped structural body returns from this state before elastic deformation, the end of the electric wire along the long arc-shaped structural body has a separation distance between one end and the other end of the circular arc. Since it becomes shorter than the diameter of the wire, it is possible to prevent the end of the wire from falling off. The operator does not need to keep holding the electric wire until the end of the electric wire is attached to the electric wire end cover by placing the electric wire along the component and closing the one and the other components. Therefore, the workability of the end treatment of the electric wire can be improved by making it easy to attach the end of the electric wire to the electric wire end cover.

本発明に係る電線端末カバーは、電線の端末を収納可能な略筒形状の収納部を電線の異なる線径ごとに有する電線端末カバーにおいて、第１構成体と、第２構成体と、第１構成体及び第２構成体を開閉自在に連結する連結部とを備え、第１構成体及び第２構成体のそれぞれは、筒芯方向に並んで設けられる複数の分割円筒部であって、それぞれの分割円筒部が第１構成体と第２構成体とが閉じた状態で相手側の対応する分割円筒部と合わさって略筒形状の収納部となる複数の分割円筒部を有し、第１構成体の分割円筒部と第２構成体の分割円筒部の円弧の長さの比率が異なると共に、少なくとも円弧の長さが長い分割円筒部が弾性変形可能に構成されることを特徴とする。 The wire terminal cover according to the present invention includes a first structure, a second structure, and a first structure, each having a substantially cylindrical storage portion that can store the terminal of the wire for each different wire diameter . e Bei and a connecting portion for connecting the structure and the second structure openably, each of the first structure and the second structure, a plurality of divided cylindrical portion which is arranged in the cylinder core direction, Each of the divided cylindrical portions has a plurality of divided cylindrical portions that are combined with the corresponding divided cylindrical portions on the other side in a state where the first structural body and the second structural body are closed to form a substantially cylindrical storage portion. The ratio of the arc lengths of the divided cylindrical portion of the one component and the divided cylindrical portion of the second component is different, and at least the divided cylindrical portion having a long arc length is configured to be elastically deformable. .

かかる構成によれば、操作部を用いることにより、第１構成体と第２構成体との開閉操作を行うことができ、間接活線作業で導電部を有する電線の端末を覆うことができる。よって、このような間接活線作業においても、電線端末カバーに電線の端末を装着しやすくすることにより、更に、電線の端末処理の作業性を改善することができる。 According to such a configuration, by using the operation unit, the opening and closing operation of the first configuration body and the second configuration body can be performed, and the terminal of the electric wire having the conductive portion can be covered by the indirect hot wire operation. Therefore, also in such indirect hot wire work, the workability of the end treatment of the electric wire can be further improved by making it easy to attach the end of the electric wire to the electric wire end cover.

本発明に係る電線端末カバーの操作部は、第１構成体及び第２構成体に設けられ、且つ、絶縁操作棒の先端に設けられる間接活線把持工具の先端を挿入可能な凹部を有することが好ましい。 The operation part of the electric wire terminal cover according to the present invention has a recess provided in the first component and the second component and capable of inserting the tip of an indirect hot wire gripping tool provided at the tip of the insulating operation rod.

かかる構成によれば、間接活線把持工具の先端を凹部に挿入することにより、間接活線把持工具の開閉と連動して、第１構成体及び第２構成体の開閉を操作することができる。よって、このような間接活線作業においても、電線端末カバーに電線の端末を装着しやすくすることにより、更に、電線の端末処理の作業性を改善することができる。 According to such a configuration, the opening and closing of the first component body and the second component body can be operated in conjunction with the opening and closing of the indirect hot wire gripping tool by inserting the tip of the indirect live wire gripping tool into the recess. . Therefore, also in such indirect hot wire work, the workability of the end treatment of the electric wire can be further improved by making it easy to attach the end of the electric wire to the electric wire end cover.

本発明に係る電線端末カバーは、水の浸入を防止すべく、電線の端末の形状に応じて変形可能な防水手段を更に備えることが好ましい。 The wire terminal cover according to the present invention preferably further includes waterproof means that can be deformed according to the shape of the end of the wire in order to prevent water from entering.

収納部８，８，８は、異なる線径の電線に対応してその端末を収納することができるように、それぞれ異なる線径の電線に対応して複数備えている。これらの収納部８，８，８は、それぞれ筒芯方向と直交する幅方向（矢印Ｂの指す方向）に並んで設けられると共に、第１構成体２と第２構成体３とを閉じた状態で電線の端末を収納すべく、第１構成体２と第２構成体３とに分かれて形成される。本実施形態に係る収納部８，８，８は、３つの異なる電線の線径に対応しており、具体的には、公称断面積２００ｍｍ²、５８ｍｍ²、２５ｍｍ²に対応している。なお、ここで挙げる公称断面積（又は線径）は、これに限定されるものではなく、適宜変更することができる。対応可能な電線の種類についても、３つに限定されるものではなく、２つ以上で必要に応じて増減させることも可能である。収納部８の筒芯方向の長さは、これらの公称断面積の違いを明確に示すために、異なる長さに設定されている。具体的には、線径の最も細い２５ｍｍ²の電線を収納する収納部８が最も短くなっており、線径の最も太い２００ｍｍ²の電線を収納する収納部８が最も長くなっている。これは、収納部８，８，８の内面と電線の端末の外周面との接触範囲を線径の太いものほど多くすることにより、自重により抜けにくくすることも考慮したものである。 A plurality of storage portions 8, 8, 8 are provided corresponding to electric wires having different wire diameters so that the terminals can be stored corresponding to electric wires having different wire diameters. These storage portions 8, 8, 8 are provided side by side in the width direction (direction indicated by the arrow B) orthogonal to the cylinder core direction, and the first configuration body 2 and the second configuration body 3 are closed. In order to accommodate the end of the electric wire, the first structural body 2 and the second structural body 3 are formed separately. The storage units 8, 8, and 8 according to the present embodiment correspond to the wire diameters of three different electric wires, and specifically correspond to nominal cross-sectional areas of 200 mm ² , 58 mm ² , and 25 mm ² . In addition, the nominal cross-sectional area (or wire diameter) mentioned here is not limited to this, It can change suitably. The types of electric wires that can be handled are not limited to three, and two or more types can be increased or decreased as necessary. The lengths of the storage portion 8 in the cylinder core direction are set to different lengths in order to clearly show the difference in the nominal cross-sectional areas. Specifically, the storage unit 8 that stores the 25 mm ² electric wire with the smallest wire diameter is the shortest, and the storage unit 8 that stores the thickest 200 mm ² electric wire is the longest. This also takes into account the fact that the contact area between the inner surfaces of the storage portions 8, 8, 8 and the outer peripheral surface of the end of the electric wire is increased as the diameter of the wire increases, thereby making it difficult to remove due to its own weight.

次に、同実施形態に係る電線端末カバー２００の作用・効果について、図９〜１１を参酌しつつ説明する。図１１は、第１構成体２０２及び第２構成体２０３を開いた状態から閉じる過程を表す。電柱に引留固定される高圧絶縁電線の引留部において、引留クランプの把持部より突出する高圧絶縁電線の端末Ｗに電線端末カバー２００を装着する場合において、作業者の一人がこの電線の端末Ｗを絶縁ヤットコなどで把持して、その位置を固定する。２人目の作業者が第１構成体２０２及び第２構成体２０３を開いて、絶縁ヤットコで第２構成体２０３の操作部６を把持し、その電線の端末Ｗまで移動させる。 Next, the operation and effect of the electric wire terminal cover 200 according to the embodiment will be described with reference to FIGS. FIG. 11 shows a process of closing the first structure 202 and the second structure 203 from the opened state. When attaching the wire end cover 200 to the terminal W of the high-voltage insulated wire protruding from the gripping portion of the retaining clamp in the retaining portion of the high-voltage insulated wire secured to the utility pole, one of the workers attaches the terminal W of this wire. Grasp it with an insulating Yatco etc. and fix its position. The second worker opens the first structural body 202 and the second structural body 203, grasps the operation unit 6 of the second structural body 203 with an insulating jacket, and moves it to the terminal W of the electric wire.

装着する電線の端末Ｗの線径を確認し、第２構成体２０３の３つある構成部２３１，…のうちでこの電線の線径に対応する構成部２３１を選択する。その電線の端末Ｗを構成部２３１の底部２３１ｂ側に合わせ、分割円筒部２３１ａの両縁を弾性変形させて、分割円筒部２３１ａ及び防水手段保持部２３３に沿わせる。電線の端末Ｗは、分割円筒部２３１ａの両縁が弾性変形から復帰することによって、分割円筒部２３１ａの両縁の最短直線距離が直径より狭くなり、分割円筒部２３１ａ，…の内部に保持される。この状態で、２人目の作業者が電線の端末Ｗを離して、第２構成体２０３の操作部６若しくは閉止部５を絶縁ヤットコで把持し、可撓部材４を回動中心に第１構成体２０２と第２構成体２０３とを閉じる。閉止部５でこの第１構成体２０２及び第２構成体２０３を閉じた状態を維持させる。 The wire diameter of the terminal W of the electric wire to be attached is confirmed, and the component portion 231 corresponding to the wire diameter of the electric wire is selected from the three component portions 231,. The terminal W of the electric wire is aligned with the bottom portion 231b side of the component portion 231, and both edges of the divided cylindrical portion 231a are elastically deformed so as to be along the divided cylindrical portion 231a and the waterproof means holding portion 233. When the both ends of the divided cylindrical portion 231a are restored from elastic deformation, the shortest linear distance between both ends of the divided cylindrical portion 231a becomes smaller than the diameter of the terminal W of the electric wire, and is held inside the divided cylindrical portions 231a,. The In this state, the second worker separates the terminal W of the electric wire, holds the operation portion 6 or the closing portion 5 of the second structural body 203 with an insulating jacket, and the first configuration with the flexible member 4 as the rotation center. The body 202 and the second structural body 203 are closed. The closed portion 5 maintains the closed state of the first structural body 202 and the second structural body 203.

このように、収納部２０８，…が異なる線径の電線に対応して複数設けられており、端末処理が必要な電線の線径に適した収納部２０８，…を選んで装着することができる。収納部２０８，…は、第１構成体２０２と第２構成体２０３とが開いた状態では、第１構成体２０２と第２構成体２０３とに分かれて形成される。この第１構成体２０２及び第２構成体２０３のいずれか一方に電線の端末Ｗを沿わせる。この状態から、第１構成体２０２と第２構成体２０３とを閉じることにより、電線の端末Ｗを沿わせた第２構成体２０３に第１構成体２０３が合わさって収納部２０８，…が形成される。電線の端末Ｗは、この収納部２０８，…の内部に収納される。すなわち、従来のように電線端末カバー２００の筒芯方向Ａから収納部２０８に向けて電線の端末Ｗを挿入する必要はなく、電線の端末Ｗをその線径に対応した収納部２０８，…に収納することが容易にできる。よって、電線端末カバー２００に電線の端末Ｗを装着しやすくすることにより電線の端末処理の作業性を改善することができる。 In this way, a plurality of storage portions 208,... Are provided corresponding to wires having different wire diameters, and the storage portions 208,... Suitable for the wire diameters of the wires that require terminal processing can be selected and mounted. . In the state where the first structural body 202 and the second structural body 203 are opened, the storage portions 208 are formed separately into the first structural body 202 and the second structural body 203. The terminal W of the electric wire is placed along one of the first structural body 202 and the second structural body 203. From this state, by closing the first structural body 202 and the second structural body 203, the first structural body 203 is combined with the second structural body 203 along the end W of the electric wire to form the storage portions 208,. Is done. The terminal W of the electric wire is accommodated in the accommodating portions 208,. That is, it is not necessary to insert the end W of the electric wire from the tube core direction A of the electric wire end cover 200 toward the storage portion 208 as in the past, and the end W of the electric wire is inserted into the storage portions 208,... Corresponding to the wire diameter. It can be easily stored. Therefore, by making it easy to attach the wire end W to the wire end cover 200, the workability of the wire end processing can be improved.

また、第１構成体２０２と第２構成体２０３とに分かれて形成される部分の円弧の長さの比率が異なるため、少なくとも第１構成体２０２及び第２構成体２０３のうち円弧の長さが長い第１構成体２０２の分割円筒部２２１ａ，…が電線の端末Ｗを少なくとも中心角１８０度以上の外周面で覆うことができる。この円弧の長さが長い第１構成体２０２の分割円筒部２２１ａ，…は、円弧の一端と他端との離間距離が電線の直径より短く形成される。この円弧の長さが長い第１構成体２０２の分割円筒部２２１ａ，…は、弾性変形可能であるため、この離間距離を拡げる方向に弾性変形させることにより、この円弧の長さが長い第１構成体２０２の分割円筒部２２１ａ，…に電線の端末Ｗを沿わせることができる。円弧の長さの長い第１構成体２０２の分割円筒部２２１ａ，…がこの状態から弾性変形前に戻ることにより、円弧の一端と他端との離間距離が電線の直径より再び短くなるため、この円弧の長さの長い第１構成体２０２の分割円筒部２２１ａ，…に沿わせた電線の端末Ｗが抜け落ちるのを防止できる。作業者は、その第１構成体２０２に電線の端末Ｗを沿わせて一方の第１構成体２０２と他方の第２構成体２０３とを閉じることによって電線の端末Ｗを電線端末カバー２００に装着するまでの間、電線の端末Ｗを保持し続ける必要がなくなる。よって、電線端末カバー２００に電線の端末Ｗを装着しやすくすることにより電線の端末処理の作業性を改善することができる。 In addition, since the ratio of the arc length of the portion formed separately between the first component 202 and the second component 203 is different, at least the length of the arc of the first component 202 and the second component 203 Can divide the terminal W of the electric wire with an outer peripheral surface having a central angle of 180 degrees or more. The divided cylindrical portions 221a,... Of the first structural body 202 having a long arc are formed such that the distance between the one end and the other end of the arc is shorter than the diameter of the electric wire. Since the divided cylindrical portions 221a,... Of the first structural body 202 having a long arc length are elastically deformable, the first arc having a long arc length is obtained by elastically deforming in the direction of widening the separation distance. The terminal W of an electric wire can be along the division | segmentation cylindrical part 221a ... of the structure 202. FIG. Since the divided cylindrical portions 221a of the first structural body 202 having a long arc length return from this state before elastic deformation, the separation distance between one end and the other end of the arc becomes shorter than the diameter of the electric wire again. It is possible to prevent the end W of the electric wire along the divided cylindrical portions 221a,... Of the first structural body 202 having a long arc from falling off. The operator places the terminal W of the electric wire along the first structural body 202 and closes the first first structural body 202 and the other second structural body 203 to attach the terminal W of the electric wire to the electric terminal cover 200. In the meantime, there is no need to keep holding the terminal W of the electric wire. Therefore, by making it easy to attach the wire end W to the wire end cover 200, the workability of the wire end processing can be improved.

なお、同実施形態に係る電線端末カバー２００は、第１構成体２０２及び第２構成体２０３のうち円弧の長さが長い第１構成体２０２の分割円筒部２２１ａが弾性変形可能な材質で成形される例を説明したが、これに限定されるものではない。第１構成体２０２及び第２構成体２０３のうち円弧の長さが長い第１構成体２０２の分割円筒部２２１ａ，…の中心角１８０度以上の円弧の範囲が弾性変形可能な材質で成形されておればよい。また、この第１構成体２２１の分割円筒部２２１ａ，…の弾性変形の際に、隣接する分割円筒部２２１ａ，…とを接続する補強部２２２，…がその妨げとなる場合、この補強部も弾性変形可能な材質で成形してもよく、又は、補強部を設けなくてもよい。 In addition, the electric wire terminal cover 200 according to the embodiment is formed of a material that can elastically deform the divided cylindrical portion 221a of the first structural body 202 having a long arc length among the first structural body 202 and the second structural body 203. Although the example to be described was demonstrated, it is not limited to this. Of the first structural body 202 and the second structural body 203, an arc range having a central angle of 180 degrees or more of the divided cylindrical portion 221a,...
