Electric connector with temperature-resistant voltage-bearing structure

Abstract

The invention discloses an electric connector with a temperature-resistant voltage-bearing structure, and the electric connector comprises a metal housing, a plastic housing, a conductor contact piece, an insulator, and a sealing ring. The metal housing is provided with a stepped hole, and the plastic housing is disposed in the metal housing and formed through injection molding of engineering plastics. The conductor contact piece and the insulator are disposed in the stepped hole of the metal housing and in the plastic housing. According to the invention, the conductor contact piece is disposed in the metal housing, the plastic housing and the insulator, and enables a working environment to be completely isolated at a state of electric signal conduction. Moreover, the electric connector can achieve unidirectional voltage bearing, is simple in structure, is reliable in sealing, is good in temperature-resistant voltage-bearing performances, and is long in service life.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, which are used for the connection of instruments and equipment in high-temperature and high-pressure environments, in particular to an electrical connector with a temperature-resistant and pressure-bearing structure. Background technique [0002] In the fields of oil drilling, well logging and seabed exploration, the operating point of the drilling equipment is often in the deep hole or deep on the seabed, and electronic equipment must be carried near the operating point to realize the transmission of downhole or seabed signals. The working environment of electronic equipment is quite harsh, especially the pressure or temperature environment is far from the ground. It is usually required to work at a temperature of 200°C and a pressure environment of 140MPa. There is a technology to place electronic equipment in a closed container, and install an electrical connector with a temperat...

AI Technical Summary

Problems solved by technology

Most of the existing electrical connectors with temperature-resistant and pressure-resistant structures are ceramic insulators. The problem is that their insulation performance is poor in stability under long-term direct exposure to high temperature and high pressure environments, and ceramic insulators are prone to breakage in vibration environments. , once the above problems occur, it will cause the sealing failure of the electrical connector, directly affect the electrical performance of the connector, cause interference to the transmission of electrical signals, reduce the service life of the connector and even damage the electronic equipment in the container
