High pressure resistant switching connector

Abstract

The invention discloses a high pressure resistant switching connector, which is characterized in that ceramic insulating tubes are sleeved on the excircles on contact elements of the contactor, and at least one end of the excircles is positioned at the end openings of contact pin channels; the outer ends of the ceramic insulating tubes axially extend along the contact elements to protrude through the end openings of the contact pin channels; glass sealing members are integrally sintered between the inner walls of the channels at the inner end openings of the ceramic tubes in the contact pin channels and the contact elements, between the outer walls of the ceramic insulating tubes and the inner walls of the contact pin channels as well as between the inner walls of the ceramic insulating tubes and the contact elements; and the ceramic insulating tubes, a metal shell and sealing-in pins are solidified into a whole by the integrally sintered glass sealing members. The invention greatly improves the high pressure sealing property of the connector by or above 140MPa, so that the connector can completely bear the hydraulic pressure of the special high-pressure vessels and ensure overall sealing of the high-pressure fluid vessels not to be affected while finishing signal transmission.

Description

technical field [0001] The invention relates to a connector, in particular to a high-voltage resistant transfer connector capable of withstanding high hydraulic pressure. Background technique [0002] At present, electronic devices are installed inside and outside of some high-pressure airtight liquid containers with special working environments. In order to ensure the reliability of signal transmission, the electronic devices inside and outside the container need to be directly connected through cables. In order to ensure the high-pressure sealing performance of the container, this connection method needs to install a wall-through adapter connector on the outer shell of the high-pressure container to facilitate the connection of electronic equipment inside and outside the container. However, since the internal and external pressures of this high-pressure airtight container are as high as 140MPa during use, and the existing high-pressure-resistant connectors are sealed with ...

Problems solved by technology

However, since the internal and external pressures of this high-pressure airtight container are as high as 140MPa during use, and the existing high-pressure-resistant connectors are sealed with a simple glass sintered sealing structure, the sealing performance is only tens of MPa, which is not as high as To the sealing requirements of such high-pressure hydraulic vessels
