Abstract (en)
[origin: CN104347308A] The invention relates to a vacuum bulb (1) including a sealed chamber (4), two electrical contacts (7, 7') which move relative to one another, wherein the sealed chamber (4) includes a cylindrical body (5) closed at its ends by two metal covers (6, 6'), where each of these covers (6, 6') is connected to one of the electrical contacts (7, 7'); and a dielectric coating (12) which covers the outer surface of the chamber (4). This coating (12) includes at least two layers, an overmoulding layer and an intermediate layer (13) discontinuous and localised on the metal portions of the chamber (4) so as to cover at least partially the outer surface of the metal portions (6, 6'), where the silicone of the intermediate layer (13) includes hollow bodies, where these hollow bodies are compressible, and have a skin made of a thermoplastic material.
