PROBLEM TO BE SOLVED: To enable a cylindrical ring body to keep the structural stability and robustness of a flange body, to enable an engagement ring to engage with a contact core a number of times until the need for replacement of the engagement ring arises due to wear or fatigue with time of the engagement ring after the engagement ring is once mounted by screwing a locking screw, and also to enable the engagement ring to be replaced easily and rapidly only by screwing the locking screw.;SOLUTION: In the contact core locking method, the engagement ring 5 having the expandable flange body 52 which is urged in an expanding direction and is expanded upwardly, is mounted on a top end of the contact core insertion attachment means. By expanding the flange body at the lower end of the contact core after the contact core 3 has passed the engagement ring 5 while contracting the flange body from the lower side thereof, the contact core is locked to the top end of the insertion attachment means.;COPYRIGHT: (C)2008,JPO&INPIT
