Embodiment Construction

[0013] A glass sintered high-temperature, high-pressure sealed connector according to the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments:

[0014] by figure 1 A glass sintered electrical connector used in oil well logging is shown as an example for illustration. The high temperature and high pressure index of the connector can reach 175°C and 140MPa, and it can bear pressure at both ends. As shown in the figure, the connector includes a plurality of conductor pins 11 for transmitting current, surrounded by a glass insulator 12 and a ceramic insulator 13, and a metal shell 14 is arranged on the periphery of the glass insulator 12 and the ceramic insulator 13, the above components constitute Glass-metal sintered structure (before glass sintering, there is a sufficient gap between the ceramic insulator 13 and the metal shell 14, and the function of the ceramic insulator 13 is to increase the pressure bear...

Abstract

A glass sintered high temperature and high pressure sealing electric connector comprises conductor pins (11) used for transmitting currents, wherein a glass insulator (12) and a ceramic insulator (13) wrap each conductor pin (11), a metal outer shell (14) is arranged on the peripheries of the glass insulators (12) and on the peripheries of the ceramic insulators (13), the conductor pins (11), the glass insulators (12), the ceramic insulators (13) and the metal outer shell (14) are combined into a whole through the glass sintering process. The conductor pins (11) are made of expansion alloy, the glass insulators (12) are made of electronic seal glass, and the metal outer shell (14) is made of nickel-based superalloy. According to the electric sealing connector, pressure can be more easily produced between glass and a substrate, the micro combination degree of sealing between glass and metal is improved, and accordingly the probability that air leakage occurs in the sintering process or in the use process is greatly lowered.

Description

technical field [0001] The invention relates to a sealed connector, in particular to a glass sintered high temperature and high pressure sealed electrical connector which can be installed on a partition wall to realize high temperature and high pressure at one end, normal pressure at the other end or high temperature and high pressure at both ends. Background technique [0002] In some fields such as energy industry, geothermal and nuclear explosion, many of them involve high-pressure working conditions, even high-temperature and high-pressure working conditions. Typical applications are logging tools in underground oil drilling equipment. 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 eq...
