Claims

[Scope of utility model registration request]

This is a mounting structure in which an arcing horn is attached to a cap fixed to an insulator insulator, wherein a bracket having a flat support part is fixed to the outer surface of the cap, and a support part of the bracket is attached to the base of the arcing horn. A polymerizable flat plate part is provided, and bolt insertion holes are formed in the support part and the flat plate part,
At least one of the insertion holes is an elongated hole, and a plurality of protrusions extending in a direction substantially perpendicular to the length direction of the elongated insertion hole are provided on a surface of the support portion that overlaps with the flat plate portion. An arc horn mounting structure for an insulator, characterized in that a fitting protrusion that fits between the protrusions is provided on a surface of the flat plate part that overlaps with the support part.
