According to the air sealing signal connector, the contact part mounting body comprises the housing, the fixing sleeve, and the glass insulator for integrally sintering and fixing the housing and the fixing sleeve, and moreover, the high temperature resistant contact part is fixedly assembled into the fixing sleeve and is in sealing fitting with the fixing sleeve through the peripheral sealing ring; therefore, the fixing sleeve and the housing can be integrally fixed through the sintered glass, then the high temperature resistant contact part is fixedly assembled into the fixing sleeve, and as a result, the connector with the high temperature resistant contact part is sealed through the glass.
Description
Technical field
The present invention relates to signal connector field, particularly relate to a kind of hermetic seal signal connector and contact fixing body thereof.
Background technology
Sintered glass sealing-in connector is a kind of comparatively common electric signal connector, wherein the housing of connector forms contact fixing body together with glass insulator (sintered glass), by means of features such as gas sealing ability, resistance to elevated temperatures and good electrical properties that glass insulator is good, the highly reliable Aerospace Electric Connector that sintered glass sealing-in connector uses under becoming high pressure, high mechanical stress occasion.But current sintered glass sealing-in connector majority is the glass sintering connector of single transmission low frequency electrical number, trace it to its cause, what contain in the integrated connector then mainly because of transmission multi-signal fears high temperature contact, as light contact, coaxial contact piece etc. comprise pottery, tin bronze, polytetrafluoroethylmaterial material part and optical fiber cable and adhesive structure etc., high temperature during glass sintering cannot be born, once adopt sintered glass to carry out sealing-in, then very easily cause the above-mentioned damage fearing high temperature contact.About the structure of conventional sintering glass sealing connector, be have relevant introduction in the Chinese patent specification of CN203056237U at notification number, no longer repeat herein.
In view of above-mentioned factor, the integrated connector of current transmission multi-signal is all adopt potting structure, namely the encapsulating body formed by encapsulating by fixing for contact in the housing, in this kind of structure, contact fixing body is made up of housing and the encapsulating body that is arranged in housing.Although the problem adopting encapsulating body fixed contact therefor to some extent solve to fear high temperature contact and damage, achieve the multi-signal transmission of signal connector, it but also exists structural instability on the whole, can not one-shot forming, the defects such as environmental performance difference.
Summary of the invention
The object of the present invention is to provide a kind of hermetic seal signal connector, glass-sealed problem can not be adopted to solve the existing connector with fearing high temperature contact.
Meanwhile, the present invention also aims to the contact fixing body that above-mentioned hermetic seal signal connector is provided.
In order to solve the problem, hermetic seal signal connector of the present invention is by the following technical solutions: hermetic seal signal connector, comprise contact fixing body and fear high temperature contact, described contact fixing body to comprise in housing, housing set fixed cover and glass insulator together with being sintered to fix with fixed cover by housing, fears high temperature contact and to be fixedly assemblied in fixed cover and to be sealed and matched by circumferential seal circle and fixed cover.
Describedly fear high temperature contact and comprise optical fiber contact and/or coaxial contact piece.
Describedly fear the step surface that high temperature contact is provided with face forward, edge in the front end of fixed cover is provided with and coordinates with the step surface block fearing high temperature contact.
Contact fixing body is by the following technical solutions: contact fixing body, to comprise in housing, housing set fixed cover and glass insulator together with being sintered to fix with fixed cover by housing, described fixed cover has for fixedly mounting the installing hole fearing high temperature contact, is provided with for by circumferential seal circle and the corresponding hermetically-sealed construction feared high temperature contact and be sealed and matched in described installing hole.
Described hermetically-sealed construction is made up of the corresponding site of the internal face of fixed cover.
Describedly fear the step surface that high temperature contact is provided with face forward, edge in the front end of fixed cover is provided with and coordinates with the step surface block fearing high temperature contact.
Fixed cover set in housing, housing is comprised and glass insulator together with being sintered to fix with fixed cover by housing due to the contact fixing body of hermetic seal signal connector of the present invention, and fearing high temperature contact is fixedly be assemblied in fixed cover, by circumferential seal circle and fixed cover to be sealed and matched, therefore, in the process of producing, first by sintered glass, fixed cover and housing can be fixed together, and then will fear high temperature contact and be fixedly assemblied in fixed cover, thus the connector that can realize with fearing high temperature contact adopts glass sealing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of hermetic seal signal connector;
Fig. 2 is the assembling schematic diagram of optical fiber contact and contact fixing body.
