ABSTRACT:
A connector for clamping one or more electrical conductors has a shackle which cooperates with a screw serving to urge one end portion of a rail toward a bottom wall of the shackle. The bottom wall has a central portion flanked by two convergent lateral portions which guide one or more conductors against the internal surface of the central portion when the screw causes the end portion of the rail to approach the bottom wall. The underside of the end portion of the rail has a centrally located platform whose underside urges the conductor or conductors against the central portion of the bottom wall and which is assisted by two ridges disposed between pairs of recesses in the end portion of the rail. The lateral portions of the bottom wall have notches which receive portions of the platform, and the recesses receive portions of the corresponding lateral wall portions. The undersides of the ridges can constitute concave surfaces to further enhance the gathering, centering and clamping effect of the end portion of the rail when the screw is rotated in a direction to advance the end portion toward the inner side of the bottom wall.
