Abstract
The seal comprises a centre layer (5) of electrically insulating material, two metal outer layers (6, 7) bearing patterns (8, 9) able to be deformed by flattening out on the bearing faces (2, 3) to be sealed, so as to hold the seal while providing a sealing barrier to the connections, and intermediate layers (10, 11) of glassy material to provide connection thereto while absorbing deformations due to differential expansions.
