PROCEDE DE FIXATION POUR REALISER LA LIAISON ENTRE UNE AME ET UN ELEMENT D'ADAPTATION D'EXTREMITE METALLIQUE DANS UN ISOLATEUR EN MATERIAU POLYMERE

摘要

A securing method including the steps of inserting a core into a depression portion of a metal member having an open end portion, and connecting the metal member to the core by compressing circumferentially the core and metal member by means of a compression die is disclosed. The improvement includes a step of compressing circumferentially the core and metal member in such a manner that an overall compression portion to be compressed by means of the compression die is divided into a plurality of compression regions arranged from the open end portion of the metal member to the other end portion, and a compression pressure is applied to the compression regions successively from the open end portion to the other end portion
