Abstract

The invention relates to a high-density connector resistant to a nuclear grade environment. The high-density connector comprises a plug and a socket, wherein the plug comprises a connecting screw cap, a spline shell arranged in the connecting screw cap and limited by a check ring and a second limiting mechanism, and an insulator component arranged in the spline shell and limited by a clamp spring and a first limiting mechanism; the insulator component comprises an insulating pressing plate and a high insulator, and a double-head jack contact is arranged in the insulating pressing plate and the high insulator in a penetrating mode; a groove in the insulating pressing plate and a groove in the high insulator are communicated to form an anti-rotation groove, and the anti-rotation groove is matched with a key table in the spline shell to prevent rotation; an O-shaped sealing ring I and a ratchet are arranged outside the spline shell; a shielding strip is further arranged in the connecting screw cap and corresponds to the position of the ratchet; and the socket is composed of a socket shell, a glass cake II and a double-head pin contact which are integrally sintered together through glass. According to the connector, the insulation performance is improved, the properties of being resistant to irradiation, resistant to aging and resistant to saturation and steam, and long in service life can be realized, and the use requirements of K1 nuclear-grade environments can be met.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a high-density connector resistant to nuclear-level environments. Background technique [0002] The nuclear-grade special cables and cable connector assemblies of the CAP series nuclear power plants under the large-scale advanced pressurized water reactor and high-temperature gas-cooled reactor nuclear power plants require that the CAP series electrical connectors need to meet the K1 nuclear-resistant environment requirements, namely: high insulation ( 1TΩ or more), radiation resistance, aging resistance, saturated steam resistance, long life (60 years of service life). However, the performance of the existing common electrical connectors (insulation over 5000MΩ, service life of 14 years) obviously cannot meet the requirements of the use of CAP series electrical connectors in a nuclear environment. [0003] The 60-year service life requirement of CAP series electrical connect...
