Abstract

The invention belongs to the technical field of double coaxial signal transmission in a nuclear power industry and concretely relates to a structural member enabling a cable outer shield to be connected with a housing through a sealing joint. A connection structural member has a T-shaped thin walled tube grooved structure, and can telescope circumferentially within the range of the internal diameter. A sealing joint housing and a penetration piece housing are fastened together. A fastening nut, a metal compaction member, a rubber sealing member and the connection structural member are sleevedwith a double coaxial cable in order, and the double coaxial cable is inserted into the sealing joint housing. The rubber sealing member and the connection structural member are pushed into the sealing joint housing and force acts on the connection structural member by fastening the fastening nut, compressing the metal compaction member and fastening the rubber sealing member, so that the wide endface of the connection structural member is in tight connection with the sealing joint housing and the grooved thin walled portion of the connection structural member tightly clings to the double coaxial cable. Through reasonable structural design and assembling, a cable outer shield and the electrical penetration piece housing can be connected reliably through an electrical penetration piece sealing joint.

Description

technical field [0001] The invention belongs to the technical field of dual-coaxial signal transmission in the nuclear power industry, and in particular relates to a structural member for realizing the outer shielding connection of cables through sealing joints. Background technique [0002] The high-temperature gas-cooled reactor demonstration project is based on the fourth-generation nuclear power technology independently developed by Tsinghua University. The electrical penetrations used on the storage tank are imported from Germany, and only provide single-core coaxial cable signal transmission interfaces, without considering the shell connection of the outermost layer of the cable. Here, the outermost shielding of the twin-coaxial cable is used as the signal loop, and a good shielding connection with the shell of the penetration must be achieved, otherwise the level sensor in the storage tank cannot work normally. Therefore, the outer shielding signal is realized accordi...
