Abstract
The invention discloses a high pressure resistant switching connector, which is characterized in that ceramic insulating 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; the outer ends of the ceramic insulating tubes axially extend along the contact elements to protrude through the end openings of the 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 insulating tubes and the inner walls of the contact pin channels as well as between the inner walls of the ceramic insulating tubes and the contact elements; and the ceramic insulating 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 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 that container is inside and outside need directly connect through 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.
Summary of the invention
The purpose of this invention is to provide a kind of adaptor connector that can bear s.
Technical scheme of the present invention is: a kind of high pressure resistant switching connector; Comprise metal shell; Axially offer the contact pin passage in this metal shell; Be coated with the contact that is used for connection cable in the contact pin passage; At least be positioned on the contact on the cylindrical of contact pin passage one end port part and be arranged with ceramic insulating tube; The outer end of ceramic insulating tube extends axially the port of outstanding contact pin passage along contact, at one sintering between at least one section vias inner walls and contact between the port of the said contact pin passage other end and the ceramic insulating tube inner face, between ceramic insulating tube outer wall and the contact pin vias inner walls and between ceramic insulation inside pipe wall and the contact glass capsulation body is arranged, and said ceramic insulating tube, metal shell and contact are all fixed through the glass capsulation body of one sintering to be one.
Be positioned at the two ends of said contact on the cylindrical of contact pin tunnel ends oral area and be arranged with ceramic insulating tube respectively.
Said contact is the cup type sealing-in contact pin of weldering.
Outer circumferential surface at said metal shell also radially offers the closure gasket groove that is used for the suit O-ring seals.
On the cylindrical that is positioned at contact pin passage two ends port part on the said contact, be arranged with ceramic insulating tube respectively, the glass capsulation body of said one sintering is arranged between the vias inner walls and contact between the opposing end surface of said two ceramic insulating tubes, between ceramic insulating tube outer wall and the contact pin vias inner walls and between ceramic insulation inside pipe wall and the contact.
The present invention adopts technique scheme; All fixed through 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, particularly wherein the high voltage resistance sealing property that consolidation structure has improved connector more greatly of mixing of glass capsulation body and ceramic insulating tube makes 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 accomplishing the signal transmission, can guarantee that the integral sealing of highly pressurised liquid container is unaffected.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A portion enlarged drawing among Fig. 1.
Embodiment
Like Fig. 1, shown in Figure 2; Adaptor connector of the present invention comprises metal shell 5; Offer connecting thread on the cylindrical of metal shell 5 one ends so that the installation of connector and spacing, the end profiles of the other end is a hexagon so that tool using is installed and clamp connector.On the cylindrical at metal shell 5 middle parts, also radially offer the closure gasket groove that twice are used for the suit O-ring seals, be respectively installed with O-ring seals 4 in two closure gasket grooves.In metal shell 5, be equipped with the cup type switching sealing-in of two root beads contact pin 1 vertically, the two ends of contact pin are respectively equipped with the bonding wire cup that is used to weld cable.The position that on sealing-in contact pin 1, is positioned at metal shell 5 two ends ports is respectively installed with ceramic insulating tube 2; The ceramic insulating tube 2 at sealing-in contact pin two ends extends the port at outstanding metal shell 5 two ends respectively vertically to increase between the sealing-in contact pin and the creepage distance between sealing-in contact pin and the metal shell, increases the interior voltage performance of product.The one sintering has glass capsulation body 3 in the contact pin passage between two ceramic insulating tubes 2, between the outer wall of ceramic insulating tube 2 and the contact pin vias inner walls and between the inwall of ceramic insulating tube 2 and the contact, and all the glass capsulation body through the one sintering 3 is fixed is one for ceramic insulating tube 2, metal shell 5 and sealing-in contact pin 1.Bear inside and outside the high-pressure bottle fluid pressure through the sintering sealing strength between glass capsulation body 3, ceramic insulating tube 2, sealing-in contact pin 1 and the metal shell 5 up to 140MPa.
