Problems solved by technology

The sealing of the existing connector is basically a glass sintered sealing structure, but because the pressure in the high pressure area of ​​the downhole in the oil field is as high as 140MPa, the existing connector with a glass sintered sealing structure can only withstand a high pressure of tens of MPa, which cannot withstand 140MPa high pressure, its sealing performance cannot meet the sealing requirements of oil well measurement

Embodiment Construction

[0017] Such as figure 1 , figure 2 , image 3 As shown, the high-pressure resistant sealed connector of the present invention includes an adapter socket 101, and the adapter socket 101 includes a metal shell 5, and two channels are radially opened on the outer peripheral surface of the metal shell 5 for installing an O-shaped seal. ring seal ring groove. In the metal shell 5, there are several pin passages penetrating through its two end faces along the axial direction. Each pin passage is respectively equipped with a pin contact piece 1 along the axial direction, and the two ends of each pin contact piece 1 are respectively The end face of the metal shell protrudes from the axial extension. In the adapter socket 101, glass insulators 3 are provided between each pin contact piece 1 and the inner wall of the corresponding pin channel, and the outer circle of the pin contact piece 1 located in the pin channel and close to its one end port is sleeved with The ceramic insulat...

Abstract

The invention discloses a high pressure resistance sealed connector and an adaptor thereof. the cylinder with at least one end close to the port part of a contact pin channel, on a contact element in the adaptor is sheathed with a porcelain insulation pipe, and an integral glass sealed body is sintered between the inner wall at the port part of the porcelain insulation pipe of the contact pin channel and the contact element, between the outer wall of the porcelain insulation pipe and the inner wall of the contact pin channel and between the inner wall of the porcelain insulation pipe and the contact element, wherein the porcelain insulation pipe, a metal shell and sealing contact pins are fixed together through the integral glass sealed body. The sealed connector of the invention greatly improves the high voltage resistance sealing property of the connector so that the high voltage resistance sealing property of the connector can reach 140MPa or more and the connector can completely bear the hydraulic pressure of a special high-pressure container, and the overall sealing property of the high-pressure fluid container can not be affected while the signal transmission can be finished.

Description

technical field [0001] The invention relates to a connector, in particular to a high-pressure resistant sealed connector and a transfer socket thereof. Background technique [0002] In oil extraction, it is necessary to detect various parameters downhole at any time. The measurement signals of each sensor installed in the downhole are connected to the recorder on the uphole through cables. When connecting the sensors downhole, a high-voltage resistant transfer connector is required for connection. The transfer connector’s One end is in a high pressure area and the other end is in a low pressure area. The sealing of the existing connector is basically a glass sintered sealing structure, but because the pressure in the high pressure area of ​​the downhole in the oil field is as high as 140MPa, the existing connector with a glass sintered sealing structure can only withstand a high pressure of tens of MPa, which cannot withstand 140MPa The high pressure, its sealing performan...
