METHOD OF HIGH-FREQUENCY SEALED CABLE TERMINAL MANUFACTURING Russian patent published in 2009 - IPC H01B17/26 H01B13/32 

FIELD: electrics.

SUBSTANCE: invention can be applied for conductor insertion to sealed room or space at atomic power stations or other objects. Method of high-frequency sealed cable terminal manufacturing involves connection of flanges to cylindrical metal case and cable placement into flanges, with cable end sealing performed by 22XC oxide ceramic insulators without metal shell ring, blanched at supposed soldering points with CuTi soldering alloy in advance. Soldering is performed in vacuum furnace by eutectic AgCu solution at 850°C, and each five of six conductors around central cable cores are cut off at the level of annular groove in ceramic insulator and then connected to the sixth conductor by AgCu soldering alloy filling annular grooves in the process of soldering thus forming screens which further comprise electric connection to lead-in cable screens. Central cable conductors are sealed by soldering with AgCu soldering alloy into ceramic insulator and connected to central conductors of lead-in cables.

EFFECT: improved quality and reliability of coaxial and symmetrical screened radio frequency cables, simplified construction of end sealings, reduced labour cost of construction manufacturing.
