Embodiment Construction

[0016] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] In the containment of nuclear power plants or in some equipment that is not easy to replace, electrical connectors are required to have a long design life, and at the same time, they need to meet high temperature resistance (the ambient peak temperature is as high as 900 degrees in severe accidents), radiation resistance (cumulative dose 1.56M Gy, γ), flooding resistance (one year under flooding accident conditions), and other environmental indicators. At this time, mineral insulated cables must be used, but the manufacturing process of mineral insulated cables determines that the distance between the cores of the cables is small. It cannot directly match the spacing of the contacts of the matching electrical connector. The spacing between the two can be matched by bending and deforming the wire core, but this will seriously affect the service life...

Abstract

The invention relates to the cable fitting field, in particular a mineral insulation cable wiring structure and a wiring method thereof. The mineral insulation cable wiring method comprises: before connecting with a contact, sleeving a cable core with a stopping member so as to allow the stooping member to locate between the contact and the outgoing line component of a mineral insulation cable after the connection between the cable core and the contact; in addition, two ends of the stopping member form a stopping structure respectively at the contact member and the outgoing line component of a mineral insulation cable. A stooping member is located between an insulator and the outgoing line component of a cable, and two ends of the stopping member form a stopping structure respectively at the contact member and the outgoing line component of a mineral insulation cable, so that when the mineral insulation cable bends, the stopping member can stop the contact to solve the problem of electric connection failure caused by a cable core driving contact fallback.

Description

technical field [0001] The invention relates to the field of cable fittings, in particular to a mineral insulated cable connection structure and a connection method thereof. Background technique [0002] Some equipment in the containment of a nuclear power plant that is not easy to replace requires a design life of 60 years, and needs to meet high temperature resistance (the ambient peak temperature is as high as more than 900 degrees in a severe accident), radiation resistance (cumulative dose 1.56M Gy, γ), For environmental indicators such as flood resistance (one year under flooding accident conditions), mineral insulated cables must be used. There is a cable core inside the mineral insulated cable, and the mineral insulated cable is connected to the matching electrical connector through the contact fixed on the cable core. Under some working conditions, the cable core will drive the contact back along the insertion direction. back, causing the electrical connection betw...
