線性気密型電気コネクター。1. An airtight connector comprising a tubular metal body, a metal rod-shaped conductive connecting member arranged in a large number therein, and an insulating / sealing member interposed between them for airtight integration. In addition, the inner surface portion of the metal body has a convex step portion by its own processing, and the outer surface portion of the conductive connecting member has an outer diameter increasing portion by its own processing, The insulating / sealing member directly casts a radiation resistant organic material into the metal body to form a surface including a convex step in the metal body and a surface of the outer diameter increasing portion of the conductive connecting member. Is formed by integrally air-tightly coupling to the metal, and the axial length of the outer diameter increasing portion of the conductive connecting member is larger than that of the convex step in the metal body, For insulation and sealing by casting By providing the material for the axial length of the outer diameter increasing portion of the conductive connecting member, the convex step portion is completely embedded in the casting material, and both axial end surface portions of the insulating / sealing member and A radiation resistant airtight electrical connector, characterized in that an additional seal is further provided on both axial end portions of the outer diameter increasing portion.
