the invention relates to a method of tightly electrically connecting an electric cable to an end member such as an electric contact , it is proposed that the partly bared or stripped end of the cable be introduced into a stepped blind hole formed in a rear connection part of the member . more specifically , the bared cable end is received in two cylindrical sections of the hole , in which have been inserted beforehand a transparent sleeve , capping an inspection hole , and a metal interface ring . the unbared part of the cable is received in a cylindrical entrance section of the hole . then , by wiredrawing , the partly truncated cone - shaped , outer surface of the part is deformed in order to give it a cylindrical shape .
