Problems solved by technology

After the Fukushima accident, the monitoring time required after the serious accident was longer, even more than one year. Traditional connectors are difficult to withstand long-term radiation aging and heat aging due to the sealing of organic materials, which eventually leads to connection failure.

Abstract

The invention belongs to the technical field of a safety-level instrument of a nuclear power plant and specifically relates to a safety-level electrical connector. A plug body is cylindrical-shaped; a main sealing ring is disposed at the lower side of an annular boss at the outer side of the lower portion of the plug body; the upper portion of the plug body is provided with a limit nut; a fastening clamp is a cylinder; the lower side inside the cylinder is provided with a two-step through hole; clamp barbs are uniformly distributed at the lower portion of the through hole; the fastening clamp is sleeved on the plug body; a compacting spring is disposed between the annular boss of the plug body and the fastening clamp; a PEEK insulator A is embedded into the lower side inside the plug body; the plug body is cylindrical-shaped, and the upper portion is sleeved on the lower portion of the plug body; the lower portion of the plug body is disposed on the inner side boss of the plug body; a PEEK insulator B is embedded into the lower portion of the boss inside the plug body; female pin cores penetrate the PEEK insulator B; male pin cores penetrate the PEEK insulator A and are inserted into the female pin cores in a one-to-one correspondence manner; and sealing gaskets are disposed between the inner side boss of the plug body and the plug body.

Description

technical field [0001] The invention belongs to the technical field of safety-level instruments in nuclear power plants, and in particular relates to a safety-level electrical connector. Background technique [0002] In a nuclear power plant, the instrument needs to be connected to the signal cable through the electrical connector, and the instrument and the cable can be freely connected and disassembled through the electrical connector, so as to maintain and replace the instrument. If the instrument is of nuclear safety level, the relevant electrical connectors must also have the same safety level and have passed the relevant certification. Especially for instruments that need to operate after accidents and accidents, their electrical connectors need to continue to work under normal, earthquake, LOCA and irradiation conditions. Especially after the Fukushima accident, higher requirements have been placed on the availability of instruments under serious accidents. [0003]...
