Abstract
An insulator core including a rod (20) fitted with a sheath (12) and with insulating fins (2,3) is fixed in a metal cap (10,10') by embedding the end (1) of the rod (20) in an organic embedding substance (9) in a thimble (5,5'), which has undercut zones and a flange (7) which is bonded or crimped to the sheath in a sealed manner, and embedding the thimble (5,5') in the cap (10,10') using a cheap inorganic cement (11). The thimble is coated with an anti-adhesive layer (27) which does not adhere to the embedding cement.
