FIELD: electricity.
SUBSTANCE: invention relates to the design of electric circuits input into a vacuum chamber. Input comprises housing, insulator and current leads. Bushing is mounted in the housing through a threaded connection and a seal installed in the groove of the said bushing. Bushing is made with the possibility of placing the matrix inside it on the receiving platform through the cylindrical guide; at that, the matrix consists of current leads, dielectric stops and vacuum rubber. Current leads are made with possibility of centring and uniform clamping by stops. Clamp is installed through the internal threaded connection of the above bushing, which provides uniform compression of the matrix and filling in it of microvolume of cavities with vacuum rubber.
EFFECT: obtaining a quick-detachable structure of a sealed lead-in with a high degree of tightness.
