Electrical connection device

Abstract

The present invention relates to an electrical connection device. The device comprises: a seat cover, a connection and plugging sleeve and a cable lamp which are inserted and connected to each other in a radial direction from outside to inside in order, wherein a tail cover is connected to the end of the cable clamp. In the insertion matching section of the seat cover and the connection and plugging sleeve, an annular step structure is arranged at the inner wall of the seat cover, a first sealing structure is matched at the insertion end of the seat cover and the connection and plugging sleeve, and a second sealing structure is arranged at the insertion matching section of the seat cover and the connection and plugging sleeve; a housing with a locking structure is matched at the outer sideof the seat cover; a second insulation body limited by the step structure at the inner wall of the seat cover and a first insulation body capable extending to the direction of the seat cover are arranged in the connection and plugging sleeve along an axial direction in order, and a first location structure and a second structure which are matched to each other are respectively arranged on the first insulation body and the second insulation body; and an insulation plugging structure is arranged between the connection and plugging sleeve and the cable clamp. The electrical connection device canrealize more reliable sealing between each component and realize rapid and accurate location and installation.

Description

technical field [0001] The invention relates to a safety-level electrical connection device, which is especially suitable for but not limited to the electrical connection device used in nuclear power plants. Background technique [0002] With the development of measurement technology, equipment such as measuring instruments and meters are used more and more widely, and these devices generally need to be connected to signal cables through electrical connection devices, so electrical connection devices have played a pivotal role in industrial connection technology. Especially in special environmental conditions, such as nuclear power plants, there are usually higher requirements for the performance of electrical connection devices. The connection of electrical connection devices must be fast and effective to prevent operators from being exposed to sensitive areas. At the same time, in addition to working under normal working conditions, the electrical connection devices of nuc...

Problems solved by technology

[0003] Traditional safety-level electrical connection devices generally use a single axial seal. In this structure, the gasket must be replaced every time it is disassembled and reassembled. The gasket is usually made of rubber, which is easily damaged during the installation process, and the installation quality is not easy. Guaranteed, and only one seal, it is difficult to withstand long-term radiation, high temperature and thermal aging after the LOCA accident, and eventually lead to connection failure
