SEALED PLUG Russian patent published in 2007 - IPC H01R13/52 H01R13/62 

FIELD: instrumentation engineering; space-rocket technology, aeronautical engineering, and advanced radio electronic devices.]

SUBSTANCE: proposed sealed plug has metal shroud that incorporates cylindrical part being jointed, rectangular flange, and cylindrical wiring tail, as well as glass insulator installed within shroud and reinforced by dowel pins. Shroud accommodates intermediate steel ring assembled by tight fit, its inner diameter being equal to outer one of glass insulator. Plug shroud is built of two parts of which first one has cylindrical part being jointed and front end of rectangular flange abutting against the latter and made of light-mass metal alloys whose coefficient of linear expansion is close to that of steel, as well as second end of rectangular flange abutting against cylindrical wiring tail, and cylindrical wiring tail, both made of steel.

EFFECT: reduced size and mass at high degree of plug tightness.
