Abstract
The invention relates to a high-pressure resistant sealing connector, which comprises a metal shell. A contact piece is assembled in the metal shell through a glass cake; the external circumference of the glass cake is fixed with the inner wall of the metal shell through sintering; a bearing wall which is in insulated match with the contact piece is integrally arranged between two ends of the contact piece in the metal shell; a through hole which is used for the contact piece to pass through is formed in the bearing wall; and one side of the glass cake is fixed with one side of the bearing wall through sintering. In the using process, no matter which end of the connector bears pressure, the bearing wall can share the pressure, namely the pressure born by the connector is not limited by combination strength between the glass cake and the shell; furthermore, because of glass cake sintering, compared with a glass tube sintering mode, the sintering quality is easily ensured; and the problem that the existing electrical connector using a sintered glass insulator is bad in compression resistance is solved under the condition of ensuring 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 sealed connector.
Background technology
Adopt the electric connector of sintered glass insulator to be widely used with its good sealing property 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, after sintering, sintered glass insulator only passes through its outer peripheral face in the internal face combination of metal shell, in such cases, the adhesion of glass and metal is limited, and the power F=P*S(P that the cross section of whole sintered glass insulator is subject to represents pressure, S represents the cross-sectional area of sintered glass insulator) all to lean on the adhesion of sintered glass insulator periphery and housing to bear, therefore this structure can not be born higher sealing load, another is contact assembly wall to be set between the two ends of metal shell and on contact assembly wall, contact cavity to be set, in described contact cavity, by sintered glass insulator, assemble contact, sintered glass insulator adopts glass tube, its principle is to reduce by reducing the bearing area of sintered glass insulator the pressure that the sintered glass insulator in single contact cavity is subject to, improve the high-voltage resistance capability of product, this structure can be born large gas in theory, fluid pressure, but due to the fault of construction of itself, easily there is following problem: 1. after sintering, glass forms and piles up that (glass tube is very thin at contact around, due to hair suction phenomenon, the glass of liquefaction is climbed and is moved along contact), make sintered surface rough and uneven in surface, if raising bearing capacity, increase the thickness of glass, in a contact cavity, use a plurality of glass tubes, between each glass tube and between glass tube and housing, contact, all there is space, gas during sintering in space is difficult for getting rid of, and forms air entrapment, causes product rejection, during glass sintering in order to make the glass after sintering fine and close, be in the two ends of glass pressurizing block, and glass tube structure is difficult for pressurizing block, the vitreum burning is out not fine and close, the easy moisture absorption causes insulation, the connector key index such as withstand voltage defective.
Generally speaking, electric connector or the compressive property of existing employing sintered glass insulator are poor, or cannot guarantee the sintering quality to sintered glass insulator.
Summary of the invention
The object of the present invention is to provide a kind of high-pressure-resistant sealed connector, to solve the poor problem of compressive property of the electric connector of existing employing sintered glass insulator under guaranteeing the prerequisite of the sintering quality of sintered glass insulator.
In order to address the above problem, high-pressure-resistant sealed connector of the present invention is by the following technical solutions: high-pressure-resistant sealed connector, comprise metal shell, in described metal shell, by glass cake, be equipped with contact, together with the outer peripheral face of described glass cake is sintered to fix with the internal face of metal shell, between the two ends of the inherent contact of described metal shell, locate one every the pressure-bearing wall being provided with contact insulation coordination, described pressure-bearing wall is provided with the through hole passing for contact, together with a side of glass cake is sintered to fix with a side of pressure-bearing wall.
Described glass cake is provided with bulge loop near a side of pressure-bearing wall, described bulge loop stretches in the corresponding through hole on pressure-bearing wall, together with the outer peripheral face of bulge loop is sintered to fix with the hole wall of the through hole at its place, the inner peripheral surface of bulge loop is together with contact in the through hole at its place is sintered to fix.
Described metal shell is provided with for the outer of installation panel secure fit with corresponding and turns edge, and the described outer gusset turning edge is provided with annular groove and in annular groove, is equipped with the end-face seal ring being sealed and matched for the installation panel with corresponding around metal shell.
On described metal shell, be arranged with the side face sealing ring that at least one is sealed and matched for the hole wall of the installing hole with on corresponding installation panel, described side face sealing ring and end-face seal ring are positioned at outer the same side turning edge.
On described metal shell, be arranged with the side face sealing ring that at least one is sealed and matched for the hole wall of the installing hole with on corresponding installation panel.
Because high-pressure-resistant sealed connector of the present invention is interval with pressure-bearing wall in two ends in its metal shell, described pressure-bearing wall is provided with the through hole passing for contact, together with one side of glass cake is sintered to fix with a side of pressure-bearing wall, therefore, no matter in use which end of connector is under pressure, all can share by described pressure-bearing wall, the pressure that connector can bear is no longer subject to the restriction of the bond strength between glass cake and housing; In addition, because being adopts glass cake sintering, than the mode of glass tube sintering, more easily guarantee the quality of sintering, under guaranteeing the prerequisite of the sintering quality of sintered glass insulator, solved the poor problem of compressive property of the electric connector of existing employing sintered glass insulator.
