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
The present invention relates to a kind of connector, relate to a kind of sealed 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 elastic rubber structure, embedding fluid sealant structure or setting-in hermetically-sealed construction are adopted in the sealing of existing connector substantially, and its sealing property does not reach the seal request of this high-pressure and hydraulic container.
Summary of the invention
The purpose of this invention is to provide a kind of sealed switching connector that can bear s.
Technical scheme of the present invention is: a kind of sealed switching connector, comprise metal shell, in metal shell, offer the contact pin passage vertically, be coated with the contact that is used for connection cable in the contact pin passage, at least be positioned on the described contact on the cylindrical of contact pin passage one end port part and be arranged with earthenware, between at least one section vias inner walls and contact between the port of the contact pin passage other end and the earthenware inner face, the one sintering has the glass capsulation body, described earthenware between earthenware outer wall and the contact pin vias inner walls and between earthenware inwall and the contact, metal shell and sealing-in contact pin are fixed by the glass capsulation body of described one sintering to be one.
Be provided with in described metal shell correspondence axially to dig on the end end face of ceramic insulating tube and be provided with groove, a corresponding end port that is provided with ceramic insulating tube is opened on the groove bottom of this groove in the described contact pin passage, be provided with the insulating mounting plate in the described groove, described each contact is set in the described insulating mounting plate, and described insulating mounting plate is bonding with metal shell and ceramic insulating tube and sealing-in contact pin respectively by bonding agent.
Described contact is the cup type sealing-in contact pin of weldering, and the two ends of this sealing-in contact pin are respectively arranged with the bonding wire cup.
Outer circumferential surface at described metal shell also radially offers the closure gasket groove that is used for the suit O-ring seals.
On the cylindrical of described metal shell one end, offer connecting thread.
Be arranged with earthenware respectively on the cylindrical that is positioned at contact pin passage two ends port part on the described contact, the glass capsulation body of described one sintering is arranged between the vias inner walls and contact between the opposing end surface of described two ceramic insulating tubes, between earthenware outer wall and the contact pin vias inner walls and between earthenware inwall and the contact.
The present invention adopts technique scheme, all fixed by the glass insulator that is sintered to integrative-structure between its ceramic insulating tube and metal shell and the contact is one, simultaneously, sintering is formed with a glass cake structure to being sintered to the glass insulator formation support of integrative-structure between ceramic insulating tube and metal shell and the contact between contact and the contact pin vias inner walls, 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 signal transmission, can guarantee that the integral sealing of highly pressurised liquid container is unaffected. the insulating mounting plate that the metal shell two ends are provided with not only can the alignment pin direction, and can increase between the sealing-in contact pin and the creepage distance between sealing-in contact pin and the metal shell, strengthen the withstand voltage properties of connector, simultaneously, this insulating mounting plate can also play the effect of dispersion liquid pressure pressure, alleviates the pressure that ceramic insulating tube and glass capsulation insulator bear in the contact pin passage.
