Conveniently disassembled electrical connector having temperature resistance and pressure bearing

Abstract

The invention discloses a conveniently disassembled electrical connector having temperature resistance and pressure bearing. The electrical connector comprises a plastic housing, a conductor contact piece, a crimping sleeve, a pull ring and a sealing ring; the plastic housing is of a cylindrical structure which is provided with a sealing groove on an outer wall; the conductor contact piece is a rod piece; the pull ring and the crimping sleeve are combined together; the plastic housing wraps the conductor contact piece and the crimping sleeve in an injection moulding manner; and the sealing ring is arranged in the sealing groove of the plastic housing. According to the electrical connector disclosed by the invention, through the plastic housing and the sealing ring, a working environment where electrical signals at the two ends of the conductor contact piece are in a conducting state is isolated completely, and the conductor contact piece bears a pressure unidirectionally in the plastic housing; through moulding the crimping sleeve which is crimped with the pull ring in the plastic housing in an injection manner, the electrical connector can be taken out from a container by pulling the pull ring, thereby being convenient to disassemble the electrical connector; and the electrical connector has the advantages of convenience in disassembly, simple in structure, reliability in sealing, and good temperature resistance and pressure bearing properties.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, which are used for the connection of instruments under high-temperature and high-pressure environments, in particular a detachable electrical connector with temperature resistance and pressure resistance. 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 temperature-resistan...

AI Technical Summary

Problems solved by technology

In order to ensure that the connector has good electrical performance, most of the existing electrical connectors with temperature-resistant and pressure-resistant structures are made of heat-resistant insulating materials. Creep deformation will occur, and it is easy to get stuck on the container wall after a long time of work. Due to the relatively poor strength of plastic materials and the effect of creep deformation, it is difficult to disassemble through the traditional tail thread method, which is difficult for the maintenance and replacement of internal electronic instruments. cause inconvenience
