Abstract (en)
[origin: WO2007045635A1] The invention relates to a seal which enables a device, such as a vacuum tube, to be mounted and removed relatively simply and easily, such as to ensure the high dielectric performance of the device. The internal and external contact surfaces of the seal are smooth and can each comprise, for example, two differently-tapered cylindrical parts (31A, 31B and 32A, 32B). At least one of the lateral surfaces comprises an annular hole (35). The invention is suitable for equipment that uses vacuum tubes for medium- and high-voltage operation.
