Abstract
The invention relates to a hermetically-sealed connector and a manufacturing method thereof. The hermetically-sealed connector comprises a shell made of an aluminum alloy; a contact element component is arranged in an inner hole of the shell; the contact element component comprises a circular body in which a plug pin contact element is hermetically arranged through sintered glass; and the contact element component is hermetically arranged in the shell through welding and fixation between the circular body and the shell. The manufacturing method of the hermetically-sealed connector comprises the following steps of: sintering and fixing the plug pin contact element of the connector in the circular body by sintering glass, then inserting the circular body and the plug pin contact element in the circular body into the inner hole of the shell of the connector, and finally hermetically sealing and fixing the circular body in the shell by welding. The shell needs not to withstand the sintering temperature, so that the sealing problem of the connector is solved without causing the shell made of an aluminum alloy to be melted down due to high temperature. In addition, the shell made of an aluminum alloy can lighten the weight of the whole connector and is favorable to lightening of the weight of equipment.

Background technology
In the prior art; The connector that is arranged on the sealed compartment needs excellent sealing performance; To guarantee the sealing property of sealed compartment; In field of connectors; The contact that is provided with in the housing of the connector that sealing property is best and the housing endoporus is to seal through sintered glass; But this sealing technology needs at high temperature glass dust to be melted; The temperature of sealing-in is very high; Therefore; The heat resistance of housing needs, and all is to be formed by the higher made of fusing point so adopt the housing of the connector of glass sealing technology, and the density of this type material is generally bigger; This has just caused the quality of connector bigger, can't realize the lighting of connector.In addition; When connector is applied on the sealed compartment; In order to guarantee sealing property; The housing and the sealed compartment of connector need be welded together; Each parts that carries out melting welding need be that same material is made; There is a kind of sealed compartment to form in the prior art by the aluminium alloy manufacturing; In order to carry out melting welding with the sealed compartment of aluminium alloy manufacturing; The housing that is used in the connector on this sealed compartment also need be made by aluminium alloy; But; The fusing point of aluminium alloy is too low, and the connector shell of aluminium alloy and the contact in it can not be realized being connected and insulating by sintered glass.
Summary of the invention
The object of the present invention is to provide a kind of hermetically sealed connector, the problem so that the connector shell that solves aluminium alloy in the prior art and the contact in it can not be connected and insulate through the sintered glass realization simultaneously, the invention still further relates to the manufacturing approach of this connector.
For realizing above-mentioned purpose; Hermetically sealed connector of the present invention adopts following technical scheme: a kind of hermetically sealed connector; Comprise the housing of processing by aluminium alloy; Be provided with the contact parts in the endoporus of said housing; The contact parts comprise ring body; Be provided with contact pin contacting piece through the sintered glass sealing in the ring body, said contact parts are arranged in the housing through the welding fixing seal between ring body and the housing.
The soldering that is welded as between described ring body and the housing connects.
Welding position between described housing and the ring body is in the rearward end of ring body, has the positioning table terrace towards front end on the outer peripheral face of ring body, has the cooperation step surface that cooperates with the positioning table terrace roof pressure of ring body on the inner hole wall of said housing.
The gap that has the scolder that produces when being installed with welding between the back segment of the outer peripheral face of described ring body and the inner hole wall of housing.
The manufacturing approach of hermetically sealed connector of the present invention adopts following technical scheme:
A kind of manufacturing approach of hermetically sealed connector is sintered to fix in a ring body through the contact pin contacting piece of sintered glass with connector earlier; Then ring body is plugged in together with the contact pin contacting piece in the ring body in the endoporus of housing of connector, adopts the mode of welding the ring body sealing to be weldingly fixed in the housing housing of said housing at last for processing by aluminium alloy.
Described welding fixed form is that soldering connects fixed form.
Described housing and ring body weld together in the rearward end of ring body, and at the positioning table terrace that is provided with on the outer peripheral face of ring body towards front end, simultaneously the cooperation step surface that cooperates with the positioning table terrace roof pressure of ring body are being set on the inner hole wall of housing.
The gap that has the scolder that produces when being installed with welding between the back segment of the outer peripheral face of described ring body and the inner hole wall of housing.
The housing of hermetically sealed connector of the present invention is an aluminium alloy; Be provided with the contact parts in the housing; The contact parts comprise ring body; Through the sintered glass sintering contact pin contacting piece is arranged in the ring body; Sealing welding between ring body and the housing; Because sintered glass has good sealing effectiveness; Therefore; Being sealed and matched between contact pin contacting piece and the ring body is good; Adding ring body is that seal weld is connected in the housing; Therefore; Sealing property of the present invention is fine, in addition, in ring body and then through the welding between ring body and the housing, is implemented in fixing in the housing because contact pin contacting piece is first sintering; So housing need not bear sintering temperature, not only solved the sealing problem of connector but also can not allow housing melt down because of bearing high temperature.In addition, the housing of connector of the present invention is formed by the aluminium alloy manufacturing, because the density of aluminium alloy is less, the housing that adopts aluminium alloy to make connector can alleviate the weight of whole connector, helps the lightweight of equipment.
Welding position between housing of the present invention and the ring body is in the rearward end of ring body; The step surface roof pressure that cooperates on positioning table terrace on the outer peripheral face of ring body and the inner hole wall of housing cooperates; Like this; After being inserted into the contact parts in the housing; The positioning table terrace cooperates the location of realization contact parts in housing with cooperating the step surface roof pressure, conveniently behind ring body, ring body is welded in the housing.
