Electrical wire connecting compression sleeve

電線接続用圧縮スリーブ

Abstract

(57)【要約】 【課題】本線寄りの箇所で切断したジャンパ線の接続に も充当できるよう、電線接続用圧縮スリーブの適用範囲 を拡大する。 【解決手段】電線接続用圧縮スリーブ1の長さ方向の一 半側1aの内径と他半側1bの内径とを、大小異なる径 とし、スリーブ1の内径が大きい方の一半側1aの一部 周面に、スリーブ1端面側から中央側へ長さ方向に延び る割溝3aを形成する。
PROBLEM TO BE SOLVED: To apply a compression sleeve even to a connection, when cutting an executed jumper wire in a place close to a main track, and to expand an applying range by forming an inside diameter of an area which reaches one end side from the central part and an inside diameter of an area reaching the other end side from the central part as large/small different diameters, and forming an expanding slot on the partial peripheral surface of an inside diameter large area. SOLUTION: The inside diameter of an area (one-half side) 1a reaching one end side from the central part and an inside diameter of an area (the other half side) 1b reaching the other end side from the central part are formed as large/small different diameters. An expanding slot 3a which extends in the lengthwise direction to the central side from the sleeve end surface side is formed on the partial peripheral surface of one half side 1a of an inside diameter large area of a compression sleeve. Thus, when connecting an executed jumper wire cut in a place close to a main track, the sleeve one half side 1a of an inside diameter large area is assigned to the jumper wire curved end part of the small round part, and the other one half side 1b of an inside diameter small area of the sleeve is assigned to the jumper wire curved end part of the large round part. The expanding slot 3a expands a compressible range width of the sleeve by a quantity, corresponding to the width.
