Description
【０００１】[0001]
本考案は電線接続部の防水処理に使用するカバ−に関し、特に、架空電線の接 続部を間接活線工法により防水処理する場合に有用なものである。 The present invention relates to a cover used for waterproofing an electric wire connecting portion, and is particularly useful when waterproofing a connecting portion of an overhead wire by an indirect live wire construction method.
【０００２】[0002]
電線接続部を防水処理する場合、割りを有する成形カバ−をその両端内部に弾 性シ−ル材（パッキング材）を付設したうえで電線接続部上に被せ、成形カバ− 両端の防水を弾性シ−ル材で行い、成形カバ−の割りを接着剤で封止するものが 公知である。 When waterproofing the wire connection part, a molded cover with a split is attached to the inside of both ends of the elastic seal material (packing material) and then covered on the wire connection part, and the waterproof property of both ends of the molded cover is elastic. It is known to use a seal material and seal the cracks of the molding cover with an adhesive.
【０００３】 この成形カバ−を用いた防水構造においては、伝統的なシ−ルテ−プ巻き付け 構造に比べて作業が簡単であり、架空電線の接続部を間接活線工法により防水処 理する場合に有利である。In the waterproof structure using this molded cover, the work is simpler than that of the traditional seal tape winding structure, and when the connection portion of the overhead wire is waterproofed by the indirect live wire construction method. Is advantageous to.
【０００４】 特に、上端ひんじ部の両側に側片部を有し、各側片部の下端に接合用耳部を設 け、この耳部同志を接着剤により接着する成形カバ−においては、上端ひんじ部 を滑節としてカバ−を開閉できるので、取扱が容易であり、間接活線工法用に有 利である。Particularly, in a molding cover in which side pieces are provided on both sides of the upper end bar and the connecting ears are provided at the lower ends of the side pieces, and the ears are bonded to each other with an adhesive, Since the cover can be opened and closed by using the upper end of the hinge as a joint, it is easy to handle and is useful for the indirect live wire construction method.
【０００５】[0005]
しかしながら、上記ひんじ式の成形カバ−を用い、前記した弾性シ−ル材を介 して電線接続部を防水すると、電線が位置するカバ−内面箇所においてカバ−内 面側から外面側に向け垂直反力が作用し、カバ−の各側片部が外側に凸の曲げ形 状で湾曲し、この結果、弾性シ−ル材に非圧縮部分が生じて隙間が発生し、所定 の防水性を確保し得ないことがある。 However, if the electric wire connecting portion is waterproofed using the above-mentioned hinge type molded cover through the elastic seal material, the electric wire is directed from the inner surface side to the outer surface side at the cover inner surface location where the electric wire is located. The vertical reaction force acts and each side piece of the cover bends in a convex shape that bends outward.As a result, a non-compressed portion is created in the elastic seal material and a gap is created, resulting in the required waterproofness. May not be secured.
【０００６】 本考案の目的は上端ひんじ部の両端に側片部を有し、各側片部の下端に接合用 耳部を有する成形カバ−において、側片部を湾曲させることなくカバ−を電線接 続部上に被せ得て充分な防水性を保証できる電線接続部用防水カバ−を提供する ことにある。An object of the present invention is to provide a molded cover having side pieces at both ends of the upper end of the hinge and a joining ear portion at the lower end of each side piece, without covering the side pieces without bending. It is an object of the present invention to provide a waterproof cover for an electric wire connecting portion which can cover the electric wire connecting portion to ensure sufficient waterproofness.
【０００７】[0007]
本考案の電線接続部用防水カバ−は上端ひんじ部の両側に側片部を有し、各側 片部内面の少なくとも両端部に２５％圧縮歪に対する応力が２ｋｇ／cm2以下の シ-ル材を有し、各側片部の下端に接合用耳部が設けられていることを特徴とす る構成であり、シ−ル材には発泡体を使用することができる。The waterproof cover for electric wire connection of the present invention has side pieces on both sides of the upper end of the elbow, and at least both ends of the inner surface of each side piece have a stress of 2 kg / cm 2 or less against 25% compressive strain. The seal material has a sealing material, and the connecting ears are provided at the lower ends of the side pieces, and a foam can be used as the sealing material.
【０００８】[0008]
シ−ル材に２５％圧縮歪に対する応力が２ｋｇ／cm2以下の低弾性率体を使用 しているから、電線と各側片部との間でのシ−ル材の大なる圧縮歪にもかかわら ず圧縮反力を充分に小にでき、各側片部の湾曲をよく防止できる。従って、側片 部の湾曲変形時に生じるシ−ル材の非圧縮箇所の発生を回避でき、良好なシ−ル 性を保証できる。Since a low elastic modulus material with a stress of 25% compressive strain of 2 kg / cm 2 or less is used for the seal material, a large compressive strain of the seal material between the wire and each side piece is used. Regardless, the compression reaction force can be made sufficiently small, and the bending of each side piece can be prevented well. Therefore, it is possible to avoid the occurrence of the non-compressed portion of the seal material that occurs when the side piece is bent and deformed, and it is possible to ensure good sealability.

以下、図面により本考案の実施例を説明する。 図１の（イ）は本考案の実施例を示す側面図、図１の（ロ）並びに図１の（ハ ）はそれぞれ図１の（イ）におけるロ−ロ断面図並びにハ−ハ断面図である。 An embodiment of the present invention will be described below with reference to the drawings. 1 (a) is a side view showing an embodiment of the present invention, and FIG. 1 (b) and FIG. 1 (c) are sectional views taken along the line of FIG. 1 (a). Is.
【００１０】 図１の（イ）乃至（ハ）において、Ａはプラスチック又はゴム製の成形カバ− であり、上端ひんじ部１の両側に側片部２を有し、各側片部２の下端には耳部３ を形成してある。４は耳部３の内面に設けた接着剤例えば粘着剤である。５は各 側片部２内面の両端部に設けた弾性シ−ル材であり、２５％圧縮歪に対する圧縮 応力が２ｋｇ／cm2以下、好ましくは５００ｇ／cm2以下の低弾性率体を使用して ある。この弾性シ−ル材５の厚みは側片部内面と耳部内面との間の間隔よりもや や厚いか、ほぼ等しくしてある。In FIGS. 1A to 1C, A is a molded cover made of plastic or rubber, and has side piece portions 2 on both sides of the upper end hinge portion 1, and An ear portion 3 is formed at the lower end. Reference numeral 4 is an adhesive, such as an adhesive, provided on the inner surface of the ear 3. Reference numeral 5 is an elastic seal material provided at both ends of the inner surface of each side piece 2, and a low elastic modulus material having a compressive stress of 2 kg / cm 2 or less for 25% compressive strain, preferably 500 g / cm 2 or less is used. There is. The thickness of the elastic seal material 5 is slightly thicker than or equal to the distance between the inner surface of the side piece portion and the inner surface of the ear portion.
【００１１】 図２は上記防水カバ−を電線の分岐接続部上に被せた状態を示し（Ｗは幹線、 ｗは支線）、開放状態のカバ−で電線接続部を挾み、耳部３，３を接着剤によっ て接着してある。 これらの耳部３，３の接着によってカバ−の各側片部２と電線Ｗ，ｗとの間の シ−ル材部分５０が大きな圧縮歪で圧縮されるが、シ−ル材に２５％圧縮歪に対 する圧縮応力が２ｋｇ／cm2以下、好ましくは５００ｇ／cm2以下といった低弾性 率体を使用しているから、その圧縮反力を充分に小さくでき、各側片部２の湾曲 変形をよく防止できる。 したがって、側片部２が湾曲変形するときに生じるシ−ル材５の非圧縮箇所（ 図において、両シ−ル材と電線外面とが寄り合う箇所Ｐに非圧縮箇所が発生し易 い）の発生を排除でき、良好なシ−ル性を保証できる。FIG. 2 shows a state in which the above-mentioned waterproof cover is covered on the branch connection portion of the electric wire (W is a trunk line, w is a branch line), and the electric wire connection portion is sandwiched by the cover in an open state, and the ear 3, 3 is bonded with an adhesive. Although the sealing material portion 50 between each side piece 2 of the cover and the electric wires W, w is compressed by a large compression strain due to the adhesion of the ears 3, 3, the sealing material is 25%. Since a low elastic modulus material with a compressive stress against compressive strain of 2 kg / cm 2 or less, preferably 500 g / cm 2 or less is used, the compression reaction force can be sufficiently reduced and the curvature of each side piece 2 can be reduced. It can prevent deformation well. Therefore, the non-compressed portion of the seal material 5 that occurs when the side piece 2 is curved and deformed (in the figure, the non-compressed portion is likely to occur at the portion P where both the seal materials and the outer surface of the wire are close to each other). Can be eliminated, and good sealing property can be guaranteed.

It is preferable to use a foam having a closed cell or a semi-closed cell.
【００１３】 上記シ−ル材の低弾性率化は、材質面以外に図３の（イ）又は図３の（ロ）に 示すように、シ−ル材５にスリット５１（スリット幅は電線外径に応じて定めら れるが、通常１〜２０ｍｍである）を設けることによって行うこともできる。In order to reduce the elastic modulus of the seal material, in addition to the material surface, as shown in FIG. Although it is determined according to the outer diameter, it is usually 1 to 20 mm).
