Abstract
An insulator core made of an organic substance and including a central rod (1) fitted with an insulating covering (4) is fixed in a metal cap (8) which is not machined. The end of the rod has undercut zones such as circumferential channels (10) or double cones (9), and a ductile metal cup (5) whose edges are made integral with the insulating covering (4) in a sealed manner is crimped on the rod. The cup (5) is itself embedded in the cap (8) by means of an organic cement or embedding substance (7) which is reinforced.
