description The utility model relates to a ceramic outgoing line sealing structure. A conducting rod is sleeved with a ceramic insulation sleeve, a second kovar alloy sleeve is sleeved and fixed on a block platform at the rear part of the conducting rod by brass soldering, the ceramic insulation sleeve is externally sleeved with a stainless steel sleeve, and a first kovar alloy sleeve is sleeved and fixed on the stainless steel sleeve by brass soldering. The sealing structure disclosed by the utility model is characterized in that the contact position between elements is sealed by brass soldering, and the soldering lines are tested in strict hydrostatic test and helium leak test. The ceramic outgoing line sealing structure can prevent the thermal stress between the elements of the outgoing line better, thereby playing a role in long-term sealing. The ceramic outgoing line sealing structure uses brass soldering, thereby effectively solving the service life problems and technical problems of aging and loosening of a sealin
