Rubber ceramic skeleton electric connector

Abstract

The invention relates to a rubber ceramic skeleton electric connector. The connector comprises a ceramic skeleton, a support ring and a plurality of inserting pins. The lower portion of the ceramic skeleton is located in the support ring, and the ceramic skeleton and the support ring are coaxially arranged; the inserting pins penetrate through the ceramic skeleton and the support ring in the axialdirection, an upper rubber body is arranged in a cavity defined by the ceramic skeleton and the inserting pins, and a lower rubber body is arranged in a cavity defined by the ceramic skeleton, the support ring and the inserting pins. According to the petroleum connector, the ceramic skeleton and the support ring are used as a pressure bearing structure, and the upper rubber body and the lower rubber body are used as an auxiliary pressure bearing structural part and a sealing part, so the pressure bearing capacity and the temperature resistance of a petroleum connector are increased to 210 MPaand 250 DEG C; the upper rubber body is matched with the internal threads, the upper rubber body is matched with the threaded section, the lower rubber body is matched with the first annular groove to increase the contact area to achieve sealing of the connector, and the ceramic framework is matched with the supporting ring, thereby achieving the extremely high pressure bearing capacity of the connector, thereby avoiding the damage caused by direct contact between ceramic and the outside.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a rubber ceramic skeleton electrical connector. Background technique [0002] At present, the structure of electrical connectors in the oil and gas field is mainly divided into three types: circular pressure-bearing structure, circular non-pressure-bearing structure, and rectangular pressure-bearing structure; among them, circular pressure-bearing connectors are divided into glass sintered connectors, rubber Vulcanized connectors, peek injection molding connectors, and glass sintered connectors have stronger pressure bearing capacity and higher temperature resistance than peek injection molding connectors; the rectangular pressure-bearing structure is mainly formed by peek injection molding. The insulation of circular glass sintered connectors in humid environments will be reduced due to ceramic moisture absorption and dirt; peek injection molded electrical connecto...
