<p>PROBLEM TO BE SOLVED: To provide an insulating clamp for low-voltage service wire which can efficiently clamp two or three service wires or messenger wires. SOLUTION: An insulating clamp for low-voltage service wire is composed of an insulating clamp body 5 having circular arcuated electric wire receiving grooves, which are formed on the internal surface of a frame type clamp main body 1 which is fitted with a U-shaped hanger 12 at the base end and the width of which becomes narrower toward the front end, at three positions on the left, right, and bottom sides in the longitudinal direction of the main body 1, and an opening 4 for guiding a wedge and inserting electric wire is formed on the top side and an insulating wedge body 6 which has recessed circular arcuated electric wire receiving grooves 7, respectively counterposed to the grooves formed in the longitudinal direction and the width of which becomes narrower toward the front end at which a guide neck section 9 with a striking section 8 facing the opening 4 is formed. This clamp clamps two or three service wires or messenger wires guided in three electric wire clamping section 10 formed of the grooves 3 and 7, when the wedge body 6 is put in the clamp body 5.</p> |
