Embodiment Construction

[0013] Such as figure 1 , figure 2 As shown, the transfer connector of the present invention includes a metal shell 5, and a connecting thread is provided on the outer circle of one end of the metal shell 5 to facilitate the installation and positioning of the connector. There are two sealing ring grooves for fitting O-shaped sealing rings radially. In the metal shell 5, there are several pin passages penetrating the bottom surface of the two grooves in the axial direction. Each pin passage is respectively equipped with solder cup-type sealing pins 1 for connecting cables. The welding ends of the two ends of the pin 1 respectively extend axially and protrude from the end face of the metal shell 5; the ports of each sealed pin 1 located at at least one end of the pin channel are respectively sleeved with a ceramic tube 3, in this embodiment , both ends of the sealing pin 1 are sleeved with ceramic tubes 3, between the two ceramic tubes 3 in the pin channel, between the outer...

Abstract

The invention discloses a sealed switching connector, which is characterized in that ceramic 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; 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 tubes and the inner walls of the contact pin channels as well as between the inner walls of the ceramic tubes and the contact elements; and the ceramic 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 sealed 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 pressure of this high-pressure airtight container is as high as 140 MPa during use, and the existing connectors are basically sealed with elastic rubber structure, potti...
