Abstract: The invention relates to the field of thermonuclear fusion and can be used for securing a blanket module to a vacuum vessel of a fusion reactor. The connecting device comprises a flexible support in the form of rods mounted between an upper flange having a concave spherical surface and a lower flange; a displacement compensator mounted on the upper flange; and a male-threaded locknut. The displacement compensator is fixedly connected to the blanket module and comprises a locking screw and a supporting sleeve, which are pivotally interconnected, a spacer sleeve, and a coupling sleeve with a spherical protuberance. The spacer sleeve is movably connected to the locking screw and pivotally connected to the upper flange of the flexible support and to the spherical protuberance of the coupling sleeve. The coupling sleeve is fixedly connected to a stop surface of the locknut.

Abstract: The invention relates to the field of thermonuclear fusion and can be used in devices for securing a blanket module to the vacuum vessel of a fusion reactor. An illustrative device comprises a flexible support in the form of rods that are mounted between two flanges, a displacement compensator, and a threaded fastening member. The displacement compensator is mounted on the flange of the flexible support, has a concave spherical surface, and is connected to the blanket module, wherein the displacement compensator comprises a locking screw, a supporting sleeve, a spacer sleeve, and a coupling sleeve. The spacer sleeve is connected to the locking screw and has a convex spherical surface and a concave spherical surface, which form a pivot connection to the flange and to the coupling sleeve respectively.
