PROBLEM TO BE SOLVED: To prevent cutting of an element wire of a lead wire, by relieving concentration of flexural stress by a filling member in a compression part port side of the lead wire of a connector metal fitting for an electric car track.SOLUTION: A connector metal fitting comprises a pair of clamps 1 for sandwiching a suspension overhead power line M, a pair of ears 2 for sandwiching a trolley wire T and a lead wire 3 for connecting between the respective clamps 1 and the ears 2. The clamps 1 comprise a connection cylinder part for connecting the lead wire. The ears 2 comprise a connection cylinder part 10. The lead wire 3 inserts both end parts into the connection cylinder parts 6 and 10, and is compressively connected together with a spacer plate 12. The spacer plate 12 is compressively connected on one end side together with the lead wire 3, and the other end side is curved by extending from the connection cylinder parts 6 and 10, so that an interval is formed between the lead wire 3 and itself. A filling member 13 is filled in this interval. The filling member 13 comprises a taper part 13b of becoming a thin wall as it becomes closer to the tail end 13a when the tail end 13a goes over the tail end 12a of the spacer plate 12.SELECTED DRAWING: Figure 1

    【課題】 電車線路用コネクタ金具のリード線の圧縮部口元での充填部材による曲げ応力の集中を緩和させ、リード線の素線切れを防止する。【解決手段】 コネクタ金具は、吊架線Mを挟持する一対のクランプ1と、トロリ線Tを挟持する一対のイヤー2と、各クランプ1とイヤー2との間を接続するリード線3とを具備する。クランプ1は、リード線接続用の接続筒部とを具備する。イヤー2は、接続筒部10を具備する。リード線3は、接続筒部6,10に両端部が挿入され、スペーサ板12と共に圧縮接続される。スペーサ板12は、一端側がリード線3と共に圧縮接続され、他端側が接続筒部6,10から延出して湾曲することにより、リード線3との間に間隔を形成する。この間隔に、充填部材13を充填する。充填部材13は末端13aがスペーサ板12の末端12aを越え、末端13aに近いほど薄肉となるテーパ部13bを備える。【選択図】 図1
