【産業上の利用分野】
この発明は、電柱に装架する被覆電線において、新しく張線および既設電線の取替による接続個所で、高所作業車のバケット内より間接活線用各種接続用工具を用い、被覆電線相互を接続する圧縮スリーブに関する。具体的には、絶縁電線端相互の被覆剥ぎ取り部を接続する圧縮スリーブと、接続部の絶縁処理のための筒状絶縁カバーと、筒状絶縁カバーの水密性を保持する絶縁テープとを一体化させ、被覆電線接続のため筒状絶縁カバー外側より圧縮ダイスにより圧縮して接続することにより、水密可能な構造を有し、作業者が被覆電線の接続部の相互の被覆を剥ぎ取り当該圧縮スリーブに挿入圧縮することにより、被覆電線の接続工事、電線方向への移動作業を効率的、電気的に安全に実施出来る圧縮スリーブの水密機構に関するものである。
【０００２】
【従来の技術】
従来、樹脂被覆した被覆電線の端部同士を接続する場合の接続作業は、以下の如くにしていた。これを図３の正面の下部を半断面にした断面図にて説明すると、まず外周面に連続突起（ｆ）を有する２本の被覆電線（ａ）の端部を所定長さだけ被覆を剥がして露出させ、当該露出導体部（ｂ）を中央にコンパウンド（２）を充填させた圧縮スリーブ（１）の両端から挿入する。次に圧縮スリーブ（１）の外側から、それぞれの導体（ｂ）二箇所ずつ、図示しない圧縮ダイスにより圧縮力である圧縮1（９）を加えて半径方向に圧縮することにより、上記２本の被覆電線（ａ）を図の位置に固定する。次にあらかじめいずれか一方の被覆電線（ａ）の片側に挿通され、両端部が中央部に比べてテーパ状に縮径成形された筒状絶縁カバー（ｄ）を圧縮スリーブ（１）との振り分け位置である図の位置まで移動する。そして、最後に被覆電線（ａ）への絶縁カバー（ｄ）の固定、水密および絶縁処理のため、絶縁カバー（ｄ）の両端部と被覆電線（ａ）との境界部分に絶縁テープ（ｃ）を規定回数巻きつけて、雨水、風水等に対する水密処理をしていた。そして、かかる接続作業は、電気を停電させたうえで、高所作業車のバケット内より作業者が各種道具を用いて、上記接続・絶縁処理作業を実施していた。最近では、電気を通電した状態で上記一連の接続作業が可能な各種間接活線用工具が用いられている。
【０００３】
【発明が解決しようとする課題】
ところが、このような電線同士の接続作業は、作業者がバケット内に上記圧縮スリーブ（１）、コンパウンド（２）、筒状絶縁カバー（ｄ）等の各部品の他、圧縮ダイス等の接続工具をも持込んだうえで上記した被覆電線端の被覆剥ぎ取り、挿入・圧縮、筒状絶縁カバーの移動、絶縁テープの巻付け等の一連の接続作業行なわなければならないが、かかる作業は、作業者にとっては各種接続用工具の持込み、取扱いが負担になる。また、被覆電線（ａ）の連続突起（ｆ）においての絶縁処理が、突起間に絶縁処理が施しにくい空隙部が存在する故に不安定になる。さらに、筒状絶縁カバー（ｄ）の外径が太く、かつ絶縁テープ（ｃ）の巻付部が軟らかい場合には、筒状絶縁カバー（ｄ）全体が軸方向に移動し易くなり、被覆電線（ａ）の外周面が筒状絶縁カバー（ｄ）の両端部によって擦れるため、樹脂被覆部分が損傷し、水密状態が維持できない、などの懸念があった。
【０００４】
また、上記に加えて、最近では作業者への作業軽減、省力化、安全確保、工事の無停電化環境下での作業等の、いわゆる間接活線作業による工事に適応可能な圧縮スリーブや筒状絶縁カバーが要求されている。さらに、外形形状が丸型絶縁電線から上記連続突起（ｆ）のある被覆電線（ａ）の導入を円滑ならしめる絶縁処理が要求され、その水密性、絶縁性を高めた圧縮スリーブの改善が必要になってきている。
【０００５】
この発明は、この様な事情に鑑みてなされたものであり、その目的は、被覆電線に対して、圧縮スリーブ、筒状絶縁カバー等の接続部品をより一層、合理的に一体化することにより、接続作業の省力化を図ると共に、接続部の電気、機械、絶縁性能を高めた圧縮スリーブの水密機構を提供することにある。
【０００６】
【課題を解決するための手段】
この発明の構成は、樹脂被覆を端部から所定長さだけ剥ぎ取って当該端部に露出導体部を設けた２本の樹脂被覆電線と、内部の中央部にコンパウンドが充填され、該コンパウンド位置まで両側から差し入れた前記露出導体部の外周面を包囲する金属性の圧縮スリーブと、前記２本の樹脂被覆電線と圧縮スリーブとを包囲する筒状絶縁カバーとからなり、
それぞれの樹脂被覆電線の露出導体部を、前記圧縮スリーブの両端部からコンパウンド位置まで挿入し、該それぞれの露出導体部を圧縮スリーブの外周面から圧縮し、予めいずれか一方の樹脂被覆電線に挿通しておいた筒状絶縁カバーを前記コンパウンド位置が中央振り分け位置となる位置まで軸方向に移動し、
前記筒状絶縁カバーの両端部と前記それぞれの樹脂被覆電線との境界部を絶縁テープで巻きつけた絶縁電線用圧縮スリーブの水密機構において、
前記絶縁テープに代えて、前記筒状絶縁カバーの両端部近傍の内部であって、前記圧縮スリーブの両端部との間に、ゴム製の防水リングを装着すると共に、
前記それぞれの樹脂被覆電線の露出導体部を、前記圧縮スリーブの両端部からコンパウンド位置まで挿入し、前記それぞれの露出導体部を前記圧縮スリーブの外周面から圧縮するに際し、
前記予めいずれか一方の樹脂被覆電線に挿通しておくべき筒状絶縁カバーを、前記コンパウンド位置が中央振り分け位置となる位置で前記圧縮スリーブの外周面に一体化しておき、
前記筒状絶縁カバーの内側であって、圧縮スリーブの両端部と、防水リングの内側端部との間に、露出導体部の挿入および圧縮後に流出したコンパウンドを貯めて気密性を高めるための空隙部である収容部を、前記圧縮スリーブと該収容部と前記防水リングとが前記筒状絶縁カバーの軸方向に沿って直列状になるように設け、
さらに、前記筒状絶縁カバーの内周面とその外周面の両端部には、それぞれ、樹脂被覆電線の挿入を容易にするためのテーパー状挿入口と、接続後の電線軸方向の移動を容易にするためのテーパー状面取部とを設け、
前記それぞれの樹脂被覆電線の露出導体部に対しては前記圧縮スリーブを介し、前記樹脂被覆部に対しては前記防水リングを介して前記筒状絶縁カバーをその外周面から圧縮してこれら部材を相互に圧着し、一体化させることにより、
前記２本の樹脂被覆電線の接続部の気密性と水密性とを保持させたこと
を特徴とする絶縁電線用圧縮スリーブの水密機構である。
【０００７】
そして、前記筒状絶縁カバーの圧縮の際には、例えば半割のリング状の圧縮ダイスを用い、軸方向に「圧縮１」（符号９）、「圧縮２」（符号１０）等と適宜、線状の圧縮位置を表した表示個所を圧縮して被覆電線の接続作業をすることになる。その際、作業者は高所作業車バケット内にて被覆電線端の被覆を剥ぎ取り、圧縮スリーブ両端に挿入し、圧縮ダイスにより圧縮位置への圧縮を行うことにより、被覆電線の接続が可能になり、高所作業車、バケット内での接続部品および各種工具の収納範囲を少なくし、作業者の作業省力化および作業が安全に行えるようになる。
【０００８】
【発明の実施の形態】
次に、この発明に係る圧縮スリーブの水密機構の実施例について、図面を参照しながら以下に説明する。
【０００９】
図１は、圧縮スリーブ（１）の正面の下半分を断面にしたこの発明に係る圧縮スリーブの水密機構の半断面図であり、図２は圧縮後の接続状態を示す半断面図である。図３は、従来から実施されている圧縮スリーブの接続した状態を示す半断面図である。
【００１０】
図１の圧縮スリーブ（１）は、外周部には耐候性、絶縁性、圧縮による変形に優れた筒状の筒状絶縁カバー（３）と、内側中央部には左右から一定長さだけ突き入れた被覆電線（ａ）の露出導体部（ｂ）との電気的性能安定のため、コンパウンド（２）を充填している。そして、電気的性能に優れた圧縮スリーブ（１）を圧入、または圧縮スリーブ（１）と筒状絶縁カバー（３）を一体成形により固定し、筒状絶縁カバー（３）両端の内面は被覆電線（ａ）の端部被覆剥ぎ取りされた露出導体部（ｂ）と被覆電線（ａ）を間接活線用挿入工具等で容易に挿入可能なテーパー状の挿入口（６）を設け、外側には被覆電線（ａ）の接続後、被覆電線（ａ）方向への移動による障害物に対し容易に移動出来るテーパー部（７）を設けている。
【００１１】
また、筒状絶縁カバー（３）の内側には、被覆電線（ａ）挿入後外接し圧縮に依り被覆電線（ａ）の外側と筒状絶縁カバー（３）との内接する隙間に密着し、水密性を保持可能な柔軟な筒状の合成ゴム材料により、筒状絶縁カバー（３）内面の凹部に固定された防水リング（４）を有する。そして、その内側と圧縮スリーブ（１）端部間には、露出導体部（ｂ）挿入および圧縮後に流出コンパウンド（２）を貯めて気密性を高めるための収容部（５）を設けてある。すなわち、この収容部（５）は、図１が示しているように、筒状絶縁カバー（３）の内側において、圧縮スリーブ（１）と、当該収容部（５）と、防水リング（４）とが、筒状絶縁カバー（３）の軸方向に沿って、直列状になるように設けられている。
ここで、被覆電線（ａ）の挿入は、樹脂被覆を剥ぎ取った露出導体部（ｂ）を、筒状絶縁カバー（３）両端の挿入口（６）より挿通し、圧縮スリーブ（１）の中央部に位置する凸部１ａまで挿入することになる。
【００１２】
図２は、圧縮スリーブに被覆電線（ａ）、露出導体部（ｂ）部を筒状絶縁カバー（３）両端側より挿入圧縮位置（８）上を規定の一対の圧縮ダイス（ｅ）により、圧縮スリーブ（１）位置における圧縮１（９）及び防水リング（４）位置は圧縮２（１０）を圧縮することにより、左右の露出導体部（ｂ）は圧縮スリーブ（１）を介して接続され、かつ電気的に導通されることになる。この場合、流出したコンパウンド（２）は左右の収容部（５）へ貯まり、防水リング（４）と被覆電線（ａ）間の水密性は圧縮２（１０）により施されることになり、一対の圧縮ダイス（ｅ）により圧縮１（９）及び圧縮２（１０）を同一に圧縮することが可能になる。
【００１３】
【００１４】
【発明の効果】
この発明は、前述したように、防水リングが内面に固定された筒状絶縁カバー内に圧入、または筒状絶縁カバーと一体成形により固定された圧縮スリーブを使用するので、丸型絶縁電線および連続突起状のある絶縁電線の接続や、高所作業車バケット内の接続部品および各種収納範囲の極小化、作業者の作業省力化、筒状絶縁カバー取付位置、被覆電線の移動による電気的安全性向上、および間接活線工法による電線接続工事の改善に優れた効果を有している。

In this invention, in the covered electric wire mounted on the utility pole, the connecting electric wires are connected to each other by using various connecting tools for indirect live wires from the inside of the bucket of the aerial work vehicle at the connection place by replacement of the extension wire and the existing electric wire. It relates to a compression sleeve to be connected. Specifically, a compression sleeve that connects the stripped portions of insulated wire ends, a cylindrical insulating cover for insulating the connecting portion, and an insulating tape that maintains the watertightness of the cylindrical insulating cover are integrated. By connecting with a compression die from the outside of the cylindrical insulating cover for connecting the covered electric wire, it has a watertight structure, and the operator peels off the mutual covering of the connecting portion of the covered electric wire and compresses it. The present invention relates to a watertight mechanism for a compression sleeve that can be efficiently and electrically safely connected to a covered wire and moved in the direction of the wire by inserting and compressing the sleeve.
[0002]
[Prior art]
Conventionally, the connection work for connecting the ends of the resin-coated covered electric wires is as follows. This will be explained with a cross-sectional view of the lower part of the front of FIG. 3. First, the end portions of the two covered electric wires (a) having continuous protrusions (f) on the outer peripheral surface are peeled off by a predetermined length. The exposed conductor (b) is inserted from both ends of the compression sleeve (1) filled with the compound (2) in the center. Next, from the outside of the compression sleeve (1), each of the two conductors (b) is compressed in the radial direction by applying compression 1 (9), which is a compression force, with a compression die (not shown). The covered electric wire (a) is fixed at the position shown in the figure. Next, the cylindrical insulating cover (d), which is inserted in advance on one side of either one of the covered electric wires (a) and whose both end portions are reduced in diameter compared to the central portion, is distributed to the compression sleeve (1).

For the user, bringing and handling various connecting tools becomes a burden. In addition, the insulation treatment at the continuous protrusion (f) of the covered electric wire (a) becomes unstable because there is a gap between the protrusions that is difficult to perform the insulation treatment. Further, when the outer diameter of the cylindrical insulating cover (d) is large and the winding portion of the insulating tape (c) is soft, the entire cylindrical insulating cover (d) is easily moved in the axial direction, and the covered electric wire Since the outer peripheral surface of (a) is rubbed by both ends of the cylindrical insulating cover (d), there is a concern that the resin-coated portion is damaged and the watertight state cannot be maintained.

Furthermore, an insulation treatment is required to smoothly introduce the covered electric wire (a) having the continuous protrusion (f) from the round insulated electric wire, and it is necessary to improve the compression sleeve with improved watertightness and insulation. It is becoming.
[0005]
The present invention has been made in view of such circumstances, and an object thereof is to further rationally integrate connection parts such as a compression sleeve and a cylindrical insulating cover with a covered electric wire. It is another object of the present invention to provide a watertight mechanism for a compression sleeve that saves connection work and enhances the electrical, mechanical, and insulating performance of the connecting portion.
