Problems solved by technology

[0003] However, the performance of glass and / or ceramic sintered products in the prior art cannot fully meet the high temperature and high pressure conditions, especially the combination effect of metal materials with glass and ceramic sintering is not ideal, resulting in metal- The sealing performance of glass-ceramics is reduced, and leakage occurs. In addition, the existing through-wall sealed connector needs to be filled with high-temperature-resistant insulating glue to form an insulating protective layer after sintering. However, the high-temperature-resistant insulating glue currently used has high-temperature resistance. It cannot fully meet the high temperature and high pressure conditions, and it is very easy to age and deform after a period of use

Abstract

The invention discloses a preparation method for an electric connector, and the method comprises the steps: assembling a metal housing with a sealing connection hole on a sealing connection die, installing a glass insulating tube and a ceramic insulating tube into the sealing connection hole at an interval, and installing conductor pins into the glass insulating tube and the ceramic insulating tube after compression; sealing the assembled structure through a sealing die box body, carrying out the sintering through a high-temperature sintering furnace, and obtaining an initial electric connector after sintering; carrying out the oxide processing of the initial electric connector; pouring high-temperature-resistant insulating glue into the grooves at two ends of the sealing connection hole of the initial connector, carrying out the room temperature solidification, and forming an insulating protection layer. The high-temperature-resistant insulating glue prepared in the invention can achieve the sealing of two ends of the electric connector, thereby preventing the external moisture and impurities from polluting the glass insulating tube and the ceramic insulating tube. Meanwhile, an insulating protection layer formed by the high-temperature-resistant insulating glue is excellent in high-temperature and high-voltage resistance, and is not liable to be aged after long-time use.

Description

technical field [0001] The invention relates to the field of preparation of electric connectors, in particular to a preparation method of the electric connector. Background technique [0002] In some fields such as the energy industry, geothermal and nuclear explosions, many of them involve high-pressure conditions, even high-temperature and high-pressure conditions. In order to ensure the reliable operation of electronic equipment, an airtight container must be provided to separate the above-mentioned high-pressure or high-temperature and high-pressure environment, and a sealed through-wall connector should be installed on the container partition wall for electrical connection with ground electronic equipment. Among the above-mentioned through-wall sealed connectors, relevant professional manufacturers and institutions at home and abroad have successfully developed many types and structures of products and their manufacturing technologies, among which glass and / or ceramic s...
