Japanese Patent JP7277330

B2

To provide an arcing horn for insulators by which a pin part of clevis metal fitting of an insulator for supporting electric wires can be visually inspected and falling due to rust can be prevented.SOLUTION: An arcing horn 1 is constituted of a fixed horn 3 with a base end part attached via a mounting fitting metal 7 to a clevis metal fitting G3 of an insulator G and extending in a sideward, and a movable horn 2 that can adjust a gap with the fixed horn 3 via a band metal fitting 4 fixable by adjusting a rotation position around a gap G4. The mounting fitting metal 7 is a pair of fitting blocks 9 respectively engaged so as to discontinue rotation around the bolt hole to a two-legs part G6, and is provided with one in which the base end of the fixed horn 3 is fixed to any one, and a bolt 8a and nut 8b fastening and fixing by penetrating together with an engaging block 9 to the two-leg part G6. A pin portion G4 of the clevis metal fitting G3 is widely exposed by fixing so as to receive the two-legs part G6 in a concave 9a, at a position of a bolt hole with a distance below from a branching point of a shade section G2 and the two-legs part G6.SELECTED DRAWING: Figure 1
