The invention relates to a sintered and sealed electric connector resistant to high pressure. The sintered and sealed electric connector comprises a metal shell, wherein a contact element is assembled inside the metal shell by a glass cake; the periphery of the glass cake is sintered and fixed with an internal wall surface of the metal shell; a bearing wall matched with the contact element in an insulating manner is integrally arranged between two ends of the contact element inside the metal shell; a through hole for the contact element to penetrate is formed in the bearing wall; the bearing wall is provided with an interface sealing body on one side adjacent to a plugging end of the electric connector, and the other side of the bearing wall is sintered and fixed with the glass cake; no matter which end of the connector is pressed, the bearing wall can share the pressure, so that the bearable pressure of the connector is not limited by the bonding strength between the glass cake and the shell any more; additionally, the adoption of the glass cake sintering is easier to guarantee the sintering quality in comparison with a glass tube sintering way, thereby solving the problem of poor pressure resistance performance of the prior electric connector adopting a sintered glass insulator on the primise of guaranteeing the sintering quality of the sintered glass insulator.
Description
Technical field
The present invention relates to electric connector field, especially a kind of high pressure resistant sintering sealed electrical connector.
Background technology
Adopt the electric connector of sintered glass insulator to obtain using widely with its excellent sealing performance and compressive property.The combining form of the metal shell of the electric connector of existing employing sintered glass and sintered glass insulator mainly contains two kinds; A kind of is all to adopt same glass cake sintering in metal shell all contacts; Behind the sintering, the sintered glass insulator only combines through the internal face of its outer peripheral face in metal shell, in such cases; The adhesion of glass and metal is limited; And the power F=P*S that the cross section of whole sintered glass insulator receives (P representes pressure, and S representes the cross-sectional area of sintered glass insulator) will lean on the adhesion of sintered glass insulator periphery and housing to bear, so this structure can not be born higher sealing load; A kind of in addition is the contact assembly wall to be set between the two ends of metal shell and the contact installing hole is set on the contact assembly wall; Assemble contact through the sintered glass insulator in the said contact installing hole; The sintered glass insulator adopts glass tube, and its principle is to reduce the pressure that the sintered glass insulator in the single contact installing hole receives through the bearing area that reduces the sintered glass insulator, improves the high-voltage resistance capability of product; This structure can be born big gas, fluid pressure in theory; But because following problem appears in itself fault of construction easily: 1. glass forms around contact and piles up that (glass tube is very thin, because a hair suction phenomenon behind the sintering; The glass of liquefaction is climbed along contact and is moved), make sintered surface rough and uneven in surface; If the raising bearing capacity, increase the thickness of glass, in a contact installing hole, use a plurality of glass tubes; Reach between each glass tube between glass tube and housing, the contact space is all arranged; Gas during sintering in the space is difficult for getting rid of, and forms air entrapment, causes product rejection; During glass sintering in order to make the glass behind the sintering fine and close, be at the two ends of glass pressurizing block, and the glass tube structure is difficult for pressurizing block, it is not fine and close to burn the vitreum that comes out, and is prone to the moisture absorption, causes insulation, connector key index such as withstand voltage defective.
Generally speaking, the electric connector or the compressive property of existing employing sintered glass insulator are poor, or can't guarantee the sintering quality to the sintered glass insulator.
Summary of the invention
The object of the present invention is to provide a kind of high pressure resistant sintering sealed electrical connector, with the problem of the compressive property difference of the electric connector that under the prerequisite that guarantees the sintering quality of sintered glass insulator, solves existing employing sintered glass insulator.
In order to address the above problem; High pressure resistant sintering sealed electrical connector of the present invention adopts following technical scheme: high pressure resistant sintering sealed electrical connector; Comprise metal shell, be equipped with contact through the glass cake in the said metal shell, the outer peripheral face of said glass cake and the internal face of metal shell are sintered to fix together; Locate one between the two ends of the inherent contact of said metal shell at a distance from the pressure-bearing wall that is provided with the contact insulation coordination; Said pressure-bearing wall is provided with the through hole that supplies contact to pass, and the pressure-bearing wall is provided with the interface sealing body near a side of the inserted terminal of electric connector, and opposite side and glass cake are sintered to fix together.
Said glass cake is provided with bulge loop near a side of pressure-bearing wall; Said bulge loop stretches in the through hole of the correspondence on the pressure-bearing wall; The hole wall of the outer peripheral face of bulge loop and the through hole at its place is sintered to fix together, and the contact in the inner peripheral surface of bulge loop and the through hole at its place is sintered to fix together.
Said metal shell is provided with and is used for turning edge with corresponding the outer of installation panel secure fit, and a said outer gusset that turns edge is provided with annular groove and in annular groove, is equipped with around metal shell and is used for the end-face seal ring that is sealed and matched with corresponding installation panel.
Be arranged with on the said metal shell at least one be used for corresponding installation panel on the side face sealing ring that is sealed and matched of the hole wall of installing hole, said side face sealing ring and end-face seal ring are positioned at outer the same side that turns edge.
Be arranged with on the said metal shell at least one be used for corresponding installation panel on the side face sealing ring that is sealed and matched of the hole wall of installing hole.
Offer draw-in groove at the side place that the pressure-bearing wall deviates from the glass cake on the internal face of said metal shell and in this draw-in groove, be installed with and be used for the O-ring seal that is sealed and matched with intermateable connector.
Since high pressure resistant sintering sealed electrical connector of the present invention in its metal shell between two ends at a distance from being provided with the pressure-bearing wall; Said pressure-bearing wall is provided with the through hole that supplies contact to pass; One side of glass cake and a side of pressure-bearing wall are sintered to fix together, therefore, no matter in use which end of connector is under pressure; All can share through said pressure-bearing wall, promptly the connector pressure that can bear no longer receives the restriction of the bond strength between glass cake and the housing; In addition; Owing to be to adopt glass cake sintering; Than the mode of glass tube sintering, guarantee the quality of sintering more easily, under the prerequisite that guarantees the sintering quality of sintered glass insulator, solved the problem of compressive property difference of the electric connector of existing employing sintered glass insulator.
