Abstract
The utility model discloses an adaptor connector. The connector is provided with a coiling welded type seal pin; a ceramic tube is sleeved on the external circle at the port part of a pin channel on two ends of the seal pin; an external end of the ceramic tube extends and projects from the port of the pin channel along the axial direction of the seal pin; a glass seal body is integrally sintered in the pin channel between two ceramic tubes, between the external wall of the ceramic insulated tube and the internal wall of the pin channel and between the internal wall of the ceramic insulated tube and the seal pin; and the ceramic insulated tube, the metal casing and the seal pin are fixed together through an integrally sintered glass seal body. The utility model greatly increases the high pressure resistance sealing performance of the connector so that the connector has the high pressure resistance sealing performance of achieving or exceeding 140MPa, completely bears the hydraulic pressure of the high pressure container and guarantees the integral seal performance of the high pressure liquid container when transmitting signals.
Description
Technical field
The utility model relates to a kind of connector, relates to a kind of high pressure resistant switching connector that bears high hydraulic pressure specifically.
Background technology
At present, in the inside and the outside of the comparatively special high-pressure sealed liquid container of a few thing environment electronic equipment is installed all, for guaranteeing the reliability of signal transmission, the electronic equipment of the inside and outside portion of container need directly connect by cable.For guaranteeing the high pressure sealing performance of container, this connected mode need be installed a kind of wall-penetrating type adaptor connector on the shell of high-pressure bottle, and the electronic equipment inside and outside with convenient container connects.But since this high-pressure closed vessel in use its inside and outside pressure all up to 140MPa, and simple glass sintering hermetically-sealed construction is adopted in existing sealing that can high voltage bearing connector, its sealing property only has tens MPa, does not reach the seal request of this high-pressure and hydraulic container.
The utility model content
The purpose of this utility model provides a kind of adaptor connector that can bear s.
The technical solution of the utility model is: a kind of adaptor connector, comprise metal shell, offer the contact pin passage that runs through its two ends end face more than two in this metal shell vertically, be equipped with the sealing-in contact pin that is used for connection cable in each contact pin passage respectively vertically, described sealing-in contact pin is coiling welded type sealing-in contact pin, each sealing-in contact pin is positioned on the cylindrical of contact pin passage two ends port part and is arranged with earthenware respectively, the outer end of two earthenwares extends axially outstanding corresponding contact pin access port along the sealing-in contact pin respectively, between the contact pin vias inner walls and contact between described two earthenwares, the one sintering has the glass capsulation body, described ceramic insulating tube between ceramic insulating tube outer wall and the contact pin vias inner walls and between ceramic insulation inside pipe wall and the sealing-in contact pin, metal shell and sealing-in contact pin are fixed by the glass capsulation body of described one sintering to be one.
Outer circumferential surface at described metal shell also radially offers the closure gasket groove that is used for the suit O-ring seals.
End face center at described metal shell one end offers tapped blind hole.
The utility model adopts technique scheme, all fixed by the glass insulator that is sintered to integrative-structure between its earthenware and metal shell and the sealing-in contact pin is one, simultaneously, sintering is formed with a glass cake structure in the contact pin passage between two earthenwares, this glass cake structure forms the glass insulator that is sintered to integrative-structure between earthenware and metal shell and the sealing-in contact pin and supports, make the whole voltage endurance capability of connector increase substantially, the high voltage resistance sealing property that consolidation structure has improved connector more greatly of mixing of glass capsulation body wherein and ceramic insulating tube particularly, make the high voltage resistance sealing property of this connector meet or exceed 140MPa, can bear the hydraulic pressure of special high-pressure bottle fully, make it when finishing the signal transmission, can guarantee that the integral sealing of highly pressurised liquid container is unaffected.
Description of drawings
